According to a first aspect of the present invention, a plug-in element for connection to a printed circuit board with plated-through holes is described. The plug-in element has a first plug-in section comprising a first row of (for example highly current-carrying) contact elements, a second plug section comprising a second row of (for example high-current-capable) contact elements, a third plug-in section comprising a third row of (for example highly currentable) contact elements.

The plug element consists in particular of a sheet-like

Metal blank which is bent at least around the first bend line. The plug-in element is in particular divided into plug-in sections which are bent relative to a, in particular central, coupling section. The coupling portion is formed within the ground plane as a reference plane. The coupling portion may be planar and completely within the ground plane. Alternatively, the

A bendline according to the present invention defines a line along which two adjacent sections, such as two adjacent mating sections or a mating section, are connected to the mating section. One Plug-in portion is thus connected, for example by means of an end or an edge on the bending line with the coupling portion. In other words, for example, the end or the edge runs within the ground plane. At each bending line, the adjacent sections run in different planes or two adjacent sections can be bent out of a common plane.

Corresponding contact elements can also be referred to as high-current-capable contact elements. The term "high current capable contact elements" may in particular the

Meaning that the contact elements in dimension, material, mutual spacing, etc., are designed such that they are suitable for carrying a high electric current. In other words, when using high current-capable contact elements, an electric current in the ampere range can be transmitted from the contact elements to the conductor tracks. A high current can be used in particular if the contact elements are specially designed to be able to transport at least 5 amperes per contact element, in particular at least 10 amperes per contact element, without jeopardizing the intended use of the connection arrangement. In other words, the

Contact elements in a high current configuration be designed so that an undesirable heating of the connection arrangement is avoided or suffers any other technical function of the connection assembly damage when such high currents are conducted by means of the contact elements. In particular, the high-current design of the

Contact elements should be designed so that the contact elements together can carry cumulative currents of at least 50 amps, in particular of at least 100 amps. The high current capability of the contact elements can be considered as given when the contact elements are connected to a vehicle battery and smoothly power from the

Vehicle battery can deliver to the connected circuit board.

In particular, the high current capability can be considered as given when contact resistance according to the Einpressnorm meet the requirements of IEC 60512-2.

The term "vibration-resistant mechanical fuse" may in particular have the meaning that an unintentional detachment of the plug element from the printed circuit board is avoided even in the presence of vibrations which act on a connection system between the plug element and the printed circuit board exhibiting technical system. as with a motorized, in particular

combustion engine operated device (especially vehicle) occur in a vibration robust mechanical fuse designed to no adverse effect on the system function. In particular, when installing the connection arrangement between the plug-in element and the circuit board in the engine compartment of an off-road vehicle, the vibrations usually occurring there should not lead to an undesirable loss of

electrical contact between the contact elements and the mating contact in the associated hole of the circuit board lead. Thus, in order to achieve the vibration robustness, the mechanical safety with regard to material, dimensions, fastening forces, etc., can be designed so that the corresponding vibrations do not lead to any undesired detachment of the vibration

Insert plug element from the printed circuit board. The connection arrangement may be for realizing the vibration robustness in accordance with

Industry standard ISO TS 16750, in particular ISO TS 16750-3, be designed. ISO 16750 defines a standard for mechanical

Load requirements for off-road vehicles. To reach the

Vibrations robustness, the connection arrangement can also be designed to meet the standard IEC 60512-4, in particular at least one of

Lower requirements according to IEC 68.2.6 (vibration sinusoidal), IEC 68-2-27 and IEC 68-2-29 (multiple shocking), IEC 68-2-64 (broadband noise), IEC-68-2-64 (Vibration in cold atmosphere) and IEC-68-2-50 and IEC-68-2-51 (vibration in warm atmosphere). The embodiment of devices according to the invention can be described in

 In accordance with ISO 16750, in particular in the versions ISO 16750-1: 2006, ISO 16750-2: 2006, ISO 16750-3: 2007, ISO 16750-4: 2006 and ISO 16750-5: 2003. For example, the mechanical fuse the plug element and the circuit board with a mechanical

Fixing force of at least about 100 Newton, in particular of at least about 200 Newton, more particularly of at least connect about 300 Newton. Such attachment forces can

be sufficient to allow sufficient vibration resistance.

The holes and the insertable into them contact elements can be an electrical load capacity according to ISO 16750-2 (in the am

 Date of filing of the European patent application EP 09163009.5, that is to say on 17.06.2009, valid version). The holes and the plug-in contact elements can in particular an electrical

Load capacity in accordance with ISO 16750-2 in the version ISO 16750-2: 2006. In other words, the contact elements can be configured mechanically and electrotechnically in such a way that the electrical load tests according to the named industrial standard are successfully completed.

In particular, each of the plug-in contact elements can be designed for an electrical load capacity of at least about 5 amperes, in particular of at least about 10 amps, more particularly of at least about 20 amps. When providing a plurality of pins or plug-in elements (which can be operated separately from each other electrically isolated) thus a total current carrying capacity of, for example, 70 amps and more can be achieved.

Each of the male contact elements can be designed with a plug force of at most about 10 Newton for insertion into one of the holes. Thus, for example, by providing five

Contact elements, which are to be inserted by a user simultaneously into a printed circuit board, a plug force of 50 Newton be required, which can still apply a user easily.

The contact elements or pins can be provided elastically and reversibly pluggable and be pluggable, for example, with forces of at most 10 Newton. This can be a reliable contact with the provided on the borehole side Gegenkontaktierung be achieved and good handling can be realized. For example, this is suitable

Plug-in element according to the invention for automotive applications, for example in tractors or buses, according to the invention may require a mechanical attachment of the plug and the board by the mechanical fuse separate from the electrical transmission to the board. such

Connections can transmit high currents and withstand high mechanical loads. At the same time, they can be plugged in several times by hand. Thus, high fastening forces at low introduction and

Pulling forces are achieved, for example when a tractor is to be repaired in the field by a user. If the contact elements have a defined distance from each other, the plug-in element according to the invention can be normalized and thereby made usable for many applications.

The contact elements can at least in the inside of the

through-hole areas to be arranged in a direction transversely to the insertion direction to be resilient. In other words, when inserting the contact elements in the associated holes of the circuit board, a force acting on the contact elements, which this in the

 Contact holes in forces. Thus, the contact elements can be under a slight bias when they dip into the contact hole.

By this bias, a secure electrical contact with the mating contacts in the borehole interior can be made possible. At the same time, such contact forces, which are first to be overcome on the user side during insertion, should be small enough to allow a simultaneous mechanical insertion of several such contacts by a user

Not to endanger manageability, that is, the insertion forces are not too large. Furthermore, the deflection characteristic of, for example, spring-like configured contact elements can be made reversible, that is, when removing the plug element from the circuit board to a lead elastic recoil springs. As a result, the plug-in element can be used several times and is not destroyed by a single use. A plastic deformation can by the yielding training of the

Contact elements and by providing the contact elements are avoided as two curved spring elements with a distance from each other.

Accordingly, it is preferred if the contact elements have two legs which leave a clearance between them. Their outer sides facing away from each other can optionally be designed, for example, convexly curved. By such a curvature, an undesirable spreading of the legs in contact with a flat surface can be avoided. When using fork contacts an elastic pluggability can be achieved.

In the inserted state of the contact elements, the two legs can begin in front of the circuit board. It may remain a portion of the legs outside the borehole, even if the plug-in element and the circuit board are hidden with each other.

The plug element may be a plug arranged at the end of one or more cables, in particular a plug connector of a

Harness. As a harness, a bundling of individual lines can be understood that transmit signals and / or working currents.

According to the invention, it is possible to use such cable harnesses as part of automotive systems, that is to say in vehicle technology or in mechanical engineering.

The plug element can be arranged on a housing containing an electronic component, for example a relay or a fuse. Alternatively, however, a housing-free configuration of the plug element possible, in which this is provided only as a sheet metal element (which can be electrically isolated, for example, with a paint to protect a user from high currents). The plug element may form part of a holder for an electronic component, for example a relay or a fuse. Thus, such an electrical component can be attached to the plug element, designed as a holder. In order to make the applicability of the connection arrangement according to the invention particularly useful for vibration-prone and high-current demanding automotive applications and the like, in addition or as an alternative to the fulfillment of the above-mentioned industrial standards, the

Connection arrangement should also be designed so that it is compatible with the IEC 60512-6 (fast temperature cycles according to Einpressnorm), in particular also according to IEC-68-2-14 (dry heat) is compatible. It is also possible that the connection arrangement in accordance with tests with

different climatic conditions according to the press-in standard IEC-60512-6 and IEC-60512-11-1 (see especially IEC 68-2-1 (coldness), IEC 68-2-2 (dry heat) and IEC 68- 2-30 (damp heat, cyclic)). The connection arrangement can also be consistent with a

Industrial climatic test according to IEC 60512-11-7 (IEC 68-2-52 (salt spray, cyclic) or IEC 68-2-60 (corrosive gas (H2S, N02, S02)) The fixing section of the plug element can be equipped with a conductor A crimped connection enables a stable, flexible connection with a wire or cable which can be realized with reasonable effort., Crimping or crimping is understood as meaning a joining process in which two components are connected to one another by plastic deformation. In the plug element, the contact elements (in particular in

Combination with the circuit board) be configured that when inserting the contact elements by hand into the holes, the contact elements are only (or exclusively) deformed in the elastic range. Thus, when inserting the contact by hand, the contact spring can actually be deformed only in the elastic range. The elastic range can be considered to be the range in which deflection and restoring force are directly proportional to each other. As the elastic range, the range in which no plastic deformation occurs can be considered.

The same or similar components in different figures are provided with the same reference numerals. The illustrations in the figures are schematic.

Fig. 1 shows a plug-in element for connection to a printed circuit board with plated-through holes. The plug element has a first

Plug portion 101 comprising a first row 121 of contact elements 106, a second plug portion having a second row of Contact elements 106, a third plug portion having a third row of contact elements 106. The first plug-in portion 101, the second plug portion and the third plug portion extend from a common ground plane 105, wherein at corresponding formed opposite the ground plane 105 portion ends of the respective first

Plug-in portion 101, the second plug-in portion 102 and the third

Plug portion 103, the corresponding first row 121 of contact elements 106, second row of contact elements 106 and third row of

Contact elements 106 is formed. Furthermore, the plug-in element has a coupling portion 104, which is formed in the ground plane 105, wherein at least the first plug-in portion 101 with the coupling portion 104 forms a common first bending line 111.

The plug element consists in particular of high current capable and bendable material, such. As copper, aluminum, silver, gold or alloys such as brass or bronze. The ohmic resistance of such a plug element or a contact element can be in the range between 10 μΩ and 10 Ω, preferably between 100 μΩ and 1 Ω. The plug element consists in particular of a sheet-like

 Metal blank which is bent at least around the first bending line 111. The plug-in element is in particular subdivided into plug-in sections 101, 102, 103, which are bent relative to the, in particular central, coupling section 104. The coupling portion 104 is formed within the ground plane 105 as a reference plane. The coupling portion 104 is planar and extends completely within the ground plane 105.

The first plug-in section 101 has a (first) bending line 111 with the coupling section 105. A bendline 111, 112, 113 defines a line along which two adjacent ones according to the present invention

Sections, such as the first mating portion 101 with the Coupling section 104 are connected. A plug-in section 101 is thus connected to the coupling section 104, for example by means of an end or an edge on the bending line 111. In other words, for example, the end or the edge of the first plug-in section 101 extends within the ground plane 105. At each bending line, the adjacent sections run in different planes in a finished plug-in element or two adjacent sections can be bent out of a common plane. The coupling section 104 extends within the ground plane 105, the first plug section 101 extending within a first plane, the second plug section 102 extending in a second plane, and the third plug section 103 extending in a third plane. The first level, the second level and / or the third level have an angle to the

Ground plane 105 of particular 90 °. The first plane has an angle of 90 ° to the second plane and the third plane.

At each plug-in section 101, 102, 103, a series of contact elements (eg contact pins) 106 are formed at an end of the respective plug-in section 101, 102, 103 opposite the ground plane. For a better overview, not all illustrated contact elements 106 are shown in the figures with the associated reference numeral 106. The contact elements 106 serve on the one hand for mechanical and in particular vibration-proof fastening of the plug element to a printed circuit board. Accordingly, the first row 121 of contact elements 106 relative to the second row 122 of contact elements 106 and / or the third row 123 of contact elements 106 are arranged at an angle of 90 ° to each other.

The plated-through holes of the circuit board and the plug-in contact elements 106 are matched to one another such that the plug-in element, in particular by hand by plugging his

Connect the contact elements 106 into the holes with the PCB and remove them by hand. By means of the contact elements 106 is the plug-in element with a vibration-resistant mechanical protection against unintentional removal of the plug-in element from the circuit board

fitted. In the exemplary embodiment of FIG. 1, the second forms

 Plug portion 102 with the coupling portion 104 from a common second bending line 112 and the third plug portion 103 forms with the

Coupling 104 a common third bending line 113 from. The first bending line 111, the second bending line 112 and the third bending line 113 are all formed in the ground plane 105. The second bending line 112 runs parallel to the third bending line 113. The first bending line 111 has an angle of 90 ° with the second bending line 112 and with the third bending line 113. The coupling portion 104 forms a rectangular surface shape within the ground plane 105, wherein at three edges of

 Coupling portion 104 each one of the bending line 111, 112, 113 can be formed.

In the illustrated embodiment, the second plug portion 102 and the third plug portion 103 are integrally connected to the coupling portion 104, respectively. Between the first plug-in portion 101, the second

Plug-in portion 102 and the third plug portion 103, a gap is provided in each case. The coupling portion has a connection portion 108 to which a fixing portion 107 for conductive attachment of a conductor is formed. The conductor is for example a current-carrying cable or a contact of another printed circuit board or another electrical device. The conductor is for example by means of a soldered connection or by means of a

Crimped (or clamping connection) fixed to the mounting portion 107. The conductor is fixed to the attachment portion 107 such that a electrically conductive connection between the conductor and the plug element is provided.

Furthermore, the coupling portion 104 has a receiving bore 109 to

Attaching a securing pin 601 (see Fig. 6 and Fig. 7) for securing the male member to the circuit board on.

Fig. 2 shows the plug-in element of Fig. 1 in a side view, in which in particular the contact elements 106 are shown. The contact elements 106 are spring-like contact elements 106 with a reversible

 Deflection characteristic. The contact elements 106 can this

For example, consist of two mutually resilient or elastically deformable legs 201, 202, which are spaced apart by a gap. In this case, the first leg 201 may be formed longer than the second leg 202. Furthermore, a free end of the first projects beyond

Leg 201, the gap between the two legs 201, 202, so that the gap to the free end of the second leg 202 by means of the first

Schenkels 201 is closed. Further, in Fig. 2, the attachment portion 107 is shown in a bent shape. The fastening region 107 may, for example, enclose a conductor in order to fasten it to the plug-in element by means of a crimp fastening. The area for crimping is for example from the

common ground plane 105 bent out, in particular

opposite to the plug-in sections 101, 102, 103.

FIG. 3 shows a semi-finished product from which the plug-in element from FIG. 1 and FIG. 2 can be produced. The semi-finished product consists for example of a flat sheet metal blank, which is formed within the ground plane 105. For example, by punching from the sheet metal blank the first

Plug portion 101 comprising the first row 121 of contact elements 106, the second plug portion 102 comprising the second row 122 of contact elements 106 and the third plug portion 103 comprising the third row 123 of contact elements 106 are formed. Furthermore, the semifinished product has the coupling portion 104, which is formed in the ground plane 105, wherein at least the first plug-in portion 101, the second plug portion 102 and the third plug portion 103 with the

Coupling portion 104, the corresponding bending lines 111, 112, 113 is formed. In other words, at the coupling portion 104 on three sides plug-in portions 101, 102, 103 by means of three different

Bending lines 111, 112, 113 arranged.

Furthermore, recesses 301 are shown which are formed on the corner regions of the coupling section 104, at which corner regions two plug-in sections 101, 102, 103 adjoin. The recesses are

For example, formed by the corresponding outer edges of the coupling portion 104 by about 1.5 mm to 2 mm into the interior of the coupling portion 104. This facilitates the production of the corresponding

Insertion portion 101, 102, 103 bend during the mutual, since a wedging of the mutually adjacent plug-in portions 101, 102, 103 directed side edges can be avoided in particular in the region of the coupling portion 104.

4 shows a plug-in element with three outer plug-in sections 101, 102, 103, in which three inner plug-in sections 104, 105, 106 are arranged in a nested manner.

The first plug-in section 101 forms with the coupling section 104 a first bending line, which runs in the ground plane 105. The first

Plug portion 101 and the second plug portion 102 further form a common fourth bending line 414, which fourth bending line 414, the first plug portion 101 and the second plug portion 102 to each other are bent. In the described embodiment, the first one

Plug-in portion 101 integrally formed with the second plug portion 102 and bent around a common fourth bending line 414 to each other. The fourth bending line 414 extends, for example, parallel to a normal of the ground plane 105. The second plug section 102 is in this

 Example, for example, separated from the coupling portion 104 or spaced.

Furthermore, the first plug-in section 101 and the third plug-in section 103 form a common fifth bending line 415 about which fifth bending line 415 the first plug-in section 101 and the third plug section 103 are bent relative to one another. In the described embodiment, the first one

Plug portion 101 integrally formed with the third plug portion 103 and bent around a common fifth bending line 415 to each other. The fifth bending line 415 runs, for example, parallel to a normal of the ground plane 105. The third plug section 103 is in this

Example, for example, separated from the coupling portion 104 or spaced. The second row 122 of contact elements 106 and the third row 123 of contact elements 106 are parallel to each other. The first row 121 of contact elements 106 extends at right angles to the second row 122 of contact elements 106 and to the third row 123 of contact elements 106.

In addition, the plug-in element has a fourth plug-in section 404 having a fourth row of contact elements 106. The fourth plug portion 404 extends from the common ground plane 105. At a section end of the fourth plug-in section 404 formed opposite the base plane 105, the corresponding fourth row of contact elements 106 is formed. The fourth plug portion 404 forms with the

Coupling 104 a common sixth bend line 416 from. In the described embodiment, the coupling portion 105 is connected to the fourth plug portion 404 integrally formed and bent around a common sixth bend line 416 to each other. For example, the sixth bendline 416 extends within the ground plane 105 and parallel to the first bendline 111.

In particular, the sixth bendline 416 is at one edge of the

Coupling portion 104 is formed, which is opposite to another edge of the coupling portion 104, on which the first bending line 111 is formed, opposite. The first plug portion 101 and the fourth plug portion 404 are thus opposite. The first plug-in portion 101 is located

for example, in the first plane and the fourth mating portion 404 in a fourth plane, wherein the first plane and the fourth plane are formed parallel to each other and spaced from each other. The first bending line 111 is formed longer than the sixth

 Bend line 416, wherein the first bending line 111 is formed in particular parallel to the sixth bending line 416. If the first bending line 111 and the sixth bending line 416 run parallel, the first bending line 111 projects beyond the ends of the sixth bending line 416. Furthermore, the extension of the first insertion section 101 along the first bending line 111 is longer than the first bending line 111

 Extension or width of the fourth plug portion 404 along the sixth bending line 416. This embodiment has the advantage that, for example, arranged on the first plug portion 101 and bent around the corresponding second and third bending lines 112, 113 second and third

Plug sections 102, 103 can wrap the fourth plug portion 404.

The plug-in element of a fifth plug-in section 405 comprises a fifth row of contact elements 106. The fifth plug-in section 405 extends from the common ground plane 105. At one, opposite to the

Ground plane 105 formed section end of the fifth plug-in section 405 is the corresponding fifth row of contact elements 106th educated. The fifth plug-in section 405 forms with the fourth plug-in section 404 a common seventh bending line 417. In the described embodiment, the fourth mating portion 404 is integrally formed with the fifth mating portion 405 and bent around a common seventh bending line 417 to each other. The seventh bending line 417 extends, for example, parallel to a normal of the ground plane 105.

Correspondingly, a sixth plug-in section 406 has a sixth row of contact elements 106 on the fourth plug-in section 404

arranged and opposite these bendable by an eighth bend line 418.

The first plug-in portion 101, the second plug-in portion 102, and the third plug-in portion 103 are formed to be the fourth

Plug portion 404, the fifth plug portion 405 and the sixth

Envelope portion 406 at least partially envelop. In other words, the fourth plug portion 404, the fifth plug portion 405 and the sixth plug portion 406 are within a space which is initially partially bounded and surrounded by the first plug portion 101, the second plug portion 102 and the third plug portion 103.

With this embodiment, the rows of contact elements 106 form rows and columns in a kind of matrix. Thus, a large number of contact elements 106 are created in a confined space, so that the mechanical connection to a circuit board is improved and at the same time an electrical connection between the contact elements 106 and the circuit board can be provided with less loss. Furthermore, a larger number of contact elements 106 can be arranged in a small space, which form a high high current carrying capacity in their entirety.

The plug element in Fig. 4 can be formed from a sheet metal blank or

be bent. For example, below the attachment portion 108 a material portion 401 may be provided, which is designed for easier handling by means of a handling or forming machine. After completion of the plug-in element, the material section 401 can be removed, for example.

5 shows a semifinished product or a sheet metal blank from which the

Plug-in element in Fig. 4 can be made. In the initial state, the respective sections 101, 102, 103, 104, 404, 405, 406 are within the ground plane 105. The fourth, fifth, seventh, and eighth bend lines 414, 415, 417, 418 are in the exemplary embodiment in FIG in particular at right angles to the first and sixth bending lines 111, 416. The first bending line 111 and the sixth bending line 416 are in particular formed parallel to one another.

 The width of the fourth plug-in section 404 along the sixth bending line 416 is shorter than the width of the first plug-in section 101 along the first bending line 111. For example, in a bending process, the fourth plug-in section 404 is first bent around the sixth bending line 416.

Subsequently, the fifth plug portion 405 is bent around the seventh bend line 417 and the sixth plug portion 406 bent around the eighth bend line 418. Subsequently, the first plug-in portion 101 becomes the first one

Bend line 111 bent and accordingly the second and third

Plug sections 102, 103 bent around the respective fourth and fifth bending lines 414, 415. After completion of the bending process, the first, second and third plug portions 101, 102, 103 surround the inner ones

Plug-in sections 404, 405, 406. In other words, on the

Coupling portion 104 on two opposite sides plug portions 101, 404 arranged by means of two different bending lines 111, 416 or formed. FIGS. 6 and 7 show a securing pin 601 as a securing element according to an exemplary embodiment of the present invention. Of the Locking pin 601 is adapted to be performed by the receiving bore 109 of the male member and by a fixing hole in a printed circuit board in and releasably secured to the printed circuit board to fix the male member to the printed circuit board.

The securing pin 601 has an end portion 602 on a fixing portion to which the securing pin is fixed to the circuit board, which end portion can protrude from the fixing hole of the circuit board. The securing pin 601 is rotatable between a mounting position and a fixing position. The end region 602 has a projection 603, which is designed such that the projection 603 can be guided through the fixing opening in the assembly position of the securing pin and prevents the projection 603 from being pulled out of the fixing opening in the fixing position. The securing pin 601 thus forms, for example, a fastening lever or a male closure part with barbs.

The fixing opening of the circuit board may be formed, for example, as a slot. The end portion 602 of the fuse pin 601 may

For example, from a cylindrical portion which extends along a cylinder axis exist. At its free end, the

End portion 602 on the projection 603, which extends in the radial direction. With respect to the cylinder axis. In other words, the free end with the projection 603 forms an elliptical or rectangular cross section. The fuse pin 601 can thus be inserted through the slot of the circuit board in the mounting position. After rotation of the securing pin 601 in the fixing position, for example, during a rotation of the securing pin 601 by 90 ° between the fixing position and the mounting position, the projection 603 wedged with the circuit board, so that pulling out the

Backup pins 601 is prevented. At an opposite end of the securing pin 601, which end is opposite the end with the projection, the securing pin may have a preparation 604 or a head, which has a larger

Diameter or larger dimensioned as the receiving opening 109 of the plug element. At the same time, the receiving opening 109 is larger

formed as the end portion 602 of the securing pin, on which end the projection 603 is formed. Thus, the locking pin 601 can be inserted with the end having the projection 603 through the receiving opening 109 and further through the fixing hole of the circuit board until the preparation 604 or the head of the securing pin 601 on the

 Coupling 104 abuts. The securing pin 601 is dimensioned in its length such that in this position the end with the projection 603 is inserted through the printed circuit board and projects out of the fixing opening. Subsequently, the securing pin 601 can be rotated for example by 90 ° about the cylinder axis, so that the projection 601 wedged with the circuit board and the plug-in element is additionally secured to the circuit board.
