Definitions
- the invention is based on a connector insert for an electrical connector according to the preamble of independent claim 1.
- the invention is based on an electrical connector comprising the connector insert according to claim 8 and a connector housing.
- the invention is based on a method for assembling a connector insert according to claim 1.
- the invention is based on a method for assembling an electrical connector according to claim 12.
- Such connector inserts are used to be inserted into a metal connector housing and to electrically ground it in order to produce a connector that is used for plug-in electrical connection with a mating connector.
- a plug-in insert has a contact carrier that is designed in two parts for constructional reasons - in particular injection molding reasons - and can be formed, for example, from an insulating body and a holding plate.
- the electrical cables connected to a cable connection area of the respective plug contact and the respective mating plug contact of a plug contact pair are electrically connected to one another in pairs in order to transmit electrical signals and/or energy between the two cables.
- the protective earthing of the metal connector housing in accordance with regulations can also serve to electrically and/or magnetically shield the electrical signals within the connector.
- the publication DE 10 2010 022 690 B4 discloses an electrical connector having a connector housing and an insulating body. At least one contact element and one ground connection contact element can be inserted into the insulating body and locked therein. It is also disclosed that the ground connection contact element is designed as a crimp contact.
- a laterally attachable contact plate is provided, which can be inserted and locked via lateral slots within a recess in the insulating body and, when inserted, is in electrically conductive contact with the ground connection contact element.
- the contact plate has a threaded hole in its base and can thus be electrically conductively connected to the connector housing via a screw connection.
- the contact plate is designed as a U-shaped component such that the lateral flanks of the contact plate have guide arms and locking arms, the guide arms locking on an undercut of the insulating body and the locking arms engaging in notches in the insulating body.
- a disadvantage of this state of the art is the high manufacturing and assembly effort of the connector, since the assembly of the contact plate requires a separate assembly step from a separate assembly direction and its lateral insertion by means of the guide and locking arms, which require a certain level of skill due to undercuts and notches. Such assembly must therefore be carried out manually and cannot be automated - or at least not with reasonable effort.
- German Patent and Trademark Office has searched the following prior art in the priority application for the present application: DE 100 09 750 A1, DE 202006 003204 U1, WO 2022/171241 A1 and WO 2022/171242 A1.
- the object of the invention is to provide a design and an assembly method for a connector insert, by means of which the connector insert can be manufactured with as little assembly effort as possible.
- the plug insert, and preferably also the entire connector should be able to be manufactured automatically.
- a connector insert serves as a component of an electrical connector and is designed to be inserted into a metallic connector housing and for PE (“Protective Earth”) grounding of the same.
- the connector insert has several one-piece plug contacts.
- the plug contacts each have a plug-in area, a retaining collar and a cable connection area separated from the plug-in area by the retaining collar.
- the cable connection area of the Plug contacts are designed as crimp connections, so that the plug contacts are crimp contacts.
- One of these plug contacts is used on the cable connection side for connection to a PE (“Protective Earth”) line and on the plug side for PE transfer to a mating connector, so that this plug contact is a PE contact.
- PE Protected Earth
- the connector insert also has an electrically conductive, separate PE connecting element.
- This PE connecting element is used on the one hand for mechanical and electrically conductive contacting of the PE contact and on the other hand for electrical and mechanical contacting of the metallic connector housing and for fastening the connector insert in the metallic connector housing.
- the PE connecting element has a cylindrical screw opening for this purpose. This screw opening has an internal thread for screwing onto the connector housing.
- the connector insert also has a contact carrier.
- the contact carrier has an insulating body with a plug-in side and a cable connection side opposite the plug-in side.
- the connector insert also has a retaining plate that can be locked onto the insulating body on the cable connection side.
- the holding plate has an insertion opening for each contact chamber for inserting the plug contact into the respective contact chamber.
- the cable connection side and the plug-in side are connected to each other via four outer surfaces of the essentially cuboid-shaped insulating body that are arranged perpendicular to each other.
- One of these outer surfaces is a PE outer surface.
- the insulating body has several contact chambers designed as through-openings, each of which accommodates a plug contact. The contact chambers are aligned in a plug-in direction that runs parallel to the outer surfaces, thus connecting the cable connection side and the plug-in side of the insulating body to one another.
- One of the contact chambers is arranged on the PE outer surface and serves to accommodate the PE contact. This contact chamber is therefore a PE contact chamber.
- the PE contact chamber is open towards the PE outer surface. This creates a PE opening in the PE outer surface. This PE opening enables the electrical and mechanical contact of the PE connecting element with the connector housing.
- the insulating body and the holding plate are designed to hold the plug contacts to be inserted and/or already inserted in the contact carrier when they are rusted together. This can be done, for example, by means of locking arms that are molded onto the holding plate and protrude into the contact chambers.
- the PE connecting element When assembling the connector insert, the PE connecting element can first be inserted into the PE contact chamber of the insulating body on the cable connection side, held in place in a form-fitting manner and initially movable in the plug-in direction, and can then be finally fixed in the contact carrier by subsequent rusting of the retaining plate on the insulating body.
- the connector insert can be assembled according to a procedure with the following steps:
- process steps are largely carried out in the specified order A; B; C and D, whereby the order of process steps C and D in relation to one another is not precisely defined, because ultimately several plug contacts are inserted into their respective contact chambers and the specified order can only be meaningfully determined for each individual plug contact.
- An electrical connector has a metallic connector housing and a connector insert of the aforementioned type inserted therein, wherein the connector insert with its PE connecting element is screwed to the connector housing by means of a screw.
- the connector can be manufactured according to the above-mentioned method with the said process steps A, B, C and D and with the following subsequent steps:
- process step F Fixing the connector insert by means of its cylindrical screw opening and the said screw to the connector housing and thereby electrically connecting the PE connecting element to the connector housing.
- process step F is particularly advantageous because the PE connecting element, in particular with its base surface, can be pulled flat against the inside of the connector housing by the screw connection and with a high pressure force, and this ensures a particularly high-quality electrically conductive connection.
- the electrically conductive connection of the PE connecting element to the connector housing in process step F can take place in that the base surface of the PE connecting element is pulled against the connector housing from the inside by the said fixing screwing, while the PE connecting element with its contact tabs simultaneously makes electrical contact with the PE contact on both sides. This creates a particularly reliable and particularly well-conductive electrically conductive connection between the PE contact and the connector housing.
- plug contacts are crimp contacts
- crimp contacts is, in addition to the high stability and excellent electrical conductivity that crimp connections generally have, particularly advantageous because in this way the plug contacts can be inserted into the contact carrier of the connector insert in a so-called "prefabricated" state - i.e. already connected to their respective electrical line.
- the crimping therefore takes place before the assembly of the connector insert described above begins.
- pre-assembled contacts can already be used, i.e. that, for example, a cable with several electrical lines and plug contacts already crimped to them in high and consistent guaranteed quality can be purchased before assembly and used during assembly.
- the PE contact is also a crimp contact. This also facilitates quality assurance and assembly, since only plug contacts of a connection type must be used in a similar way, i.e. crimp contacts by crimping.
- Another particular advantage is that both the PE connecting element and the plug contacts are only inserted into the insulating body/contact carrier from the cable connection side.
- the retaining plate is also locked to the insulating body from the cable connection side, so that there is only one assembly direction for the connector insert. This makes the assembly of the connector insert much easier and also improves its automation.
- the connector insert has the advantage of being particularly compact, i.e. it has small geometric dimensions in relation to the cable cross-sections used. This is made possible by the compact PE connection element and the one-piece, particularly compact crimp contacts. As a result, the clearance and creepage distances are small in relation to the given installation space, so that comparatively high electrical voltages can be applied to the plug contacts.
- This connector insert and the connector equipped with it therefore have both a particularly high current-carrying capacity and a particularly high dielectric strength.
- the retaining plate has a locking arm that extends into the respective contact chamber to prevent rusting of each plug contact inserted into the contact carrier.
- a plug contact inserted into the contact carrier on the cable connection side through the respective insertion opening of the retaining plate can rust in the respective contact chamber on the respective locking arm with its retaining collar.
- the PE connecting element has at least one fixing pin on the plug side for stabilizing engagement in a holding pocket of the insulating body arranged at a plug-side end of the PE contact chamber.
- the PE connecting element is held in the PE contact chamber of the insulating body in a non-rusted state of the holding plate so that it can move in the plug-in direction.
- the PE connecting element can advantageously be pushed into the contact carrier from the cable connection direction, moved into its final position and finally fixed in place using the holding plate.
- the PE connecting element can be formed inexpensively and inexpensively as a stamped and bent part from a spring-elastic sheet metal part.
- the PE connecting element can mechanically and electrically contact the PE contact on both sides.
- the PE connecting element can have two contact tabs of the PE contact that point in the plugging direction and are free-standing at the end.
- the PE connecting element can have two side walls and a base surface as a contact surface.
- the screw opening can then be arranged in the base surface.
- the base surface of the PE connecting element can be pulled against the connector housing by the screwing force and thus electrically contact the connector housing over a large area, which makes for a particularly good and safe electrical connection.
- the two side walls can be bent at right angles from the base of the PE element so that the PE connecting element has a substantially egg-shaped cross-section.
- Each of the two contact tabs can be punched out of one of these side walls and bent inwards in order to mechanically and electrically contact the plug contact inserted along these contact tabs on the cable connection side on both sides.
- the PE connecting element can have at least one outward-facing sliding runner on each of its two side walls for engaging behind a sliding edge of the insulating body. This serves to facilitate the insertion of the PE connecting element into the insulating body and to keep the PE connecting element movable in the plug-in direction in the insulating body until the retaining plate snaps into place. At the same time, these features can advantageously be implemented with very little manufacturing effort.
- Each of these two sliding edges of the insulating body can be part of one of two guide slots of the insulating body that are aligned parallel to the PE outer surface. These two guide slots can be arranged on two opposite sides of the PE contact chamber. The two guide slots can start on the cable connection side and run from there in the plug-in direction. Each of the sliding skids of the PE connecting element inserted into the insulating body can thus engage in one of the guide slots in order to initially hold the PE connecting element in the insulating body so that it can be moved in the plug-in direction.
- the holding plate has locking means for locking onto counter-locking means of the insulating body.
- the holding plate can have locking tabs with locking windows as locking means, which can be locked onto counter-locking means of the insulating body, which are designed as locking formations.
- Insulating body which are designed, for example, as ramp-shaped locking hooks, each with a sliding slope and a holding surface.
- the anti-rust means can be arranged on two opposing outer surfaces of the insulating body. Preferably, these are the two opposing outer surfaces, neither of which is the PE outer surface. This is particularly advantageous because otherwise the PE recess would make the presence of the anti-rust means difficult or impossible.
- grooved nails which are well known to those skilled in the art, can also be used to attach the retaining plate to the contact carrier.
- the metallic connector housing has a contact web on the inside.
- the connector housing can have a cylindrical through-opening in the contact web for passing through the screw to be screwed into the screw opening of the PE connecting element.
- the inside contact web of the connector housing can thus partially engage in the PE opening of the contact carrier in order to be pressed against the contact surface of the PE connecting element by means of the said screw connection and thus to connect the connector housing to the PE connecting element in a mechanical and electrically conductive manner.
- the contact web can be used as polarization protection to ensure the correct alignment of the connector insert to the connector housing.
- the holding plate can have at least one holding web which, when the holding plate is rusted, strikes against the PE connecting element inserted into the PE contact chamber on the cable connection side in order to permanently fix the PE connecting element in the contact carrier.
- the holding plate can have two holding webs, of which one each strikes against one of the two side walls of the PE connecting element. These two retaining webs can be arranged on either side of the locking arm, which serves to fix the PE contact and is therefore referred to as the PE locking arm.

- Fig. 5 the connector insert, comprising the insulating body, the PE connecting element, the holding plate and the PE contact, in an exploded view;
- Fig. 6 the connector housing with the connector insert inserted and screwed in without the PE contact in a sectional view.
- Fig. 1a and 1b show a PE connecting element 1 of a connector insert from two different views.
- the PE connecting element 1 is designed in one piece and can be manufactured inexpensively and easily as a stamped and bent part from a spring-elastic sheet metal part.
- the PE connecting element 1 has two side walls 12 and a base surface 11 connecting these two side walls 12 as a contact surface for electrical and mechanical contacting of a metallic connector housing 5 shown in Fig. 6.
- a screw opening 10 is arranged in the base surface 11.
- the screw opening 10 has an internal thread, not explicitly shown here, for screwing and fastening in the connector housing 5 by means of a screw 6 shown in Fig. 6.
- the two side walls 12 of the PE connecting element 1 are angled at right angles from the base surface 11, so that the PE connecting element 1 has a substantially U-shaped cross section in the area of the base surface 11.
- a contact tab 122 is punched out of each of these side walls 12 and bent slightly inwards.
- the PE connecting element 1 has on each of its two side walls 12 an outwardly directed sliding skid 124 for engaging behind a sliding edge 314 of an insulating body 3 shown in Fig. 3.
- Fig. 2a and 2b show the PE connection element 1 with a PE contact 2 arranged therein. It is clear that the two contact tabs 122 of the PE connection element 1 contact the PE contact 2 on both sides mechanically - and thus also electrically.
- the PE contact 2 has a plug-in area 21, a retaining collar 23 and a cable connection area 22 separated from the plug-in area 21 by the retaining collar 23.
- the cable connection area 22 of the PE contact 2 is designed as a crimp connection and thus has a crimp opening 20 for inserting and crimping an earthing line (not shown), so that the PE contact 2 is a crimp contact.
- the PE connecting element 1 is designed to electrically connect the PE contact 2, and thus the said grounding line connected to the PE contact 2 by crimping, to the connector housing 5.
- the PE connecting element 1 further comprises a plug-side fixing pin 126 on each of its two side walls 12.
- Fig. 3 shows an insulating body 3 with a view of its cable connection side and a holding plate 4 that can be locked onto the insulating body 3 on the cable connection side.
- the insulating body 3 Opposite the cable connection side, the insulating body 3 has a plug-in side that is optically concealed in the drawing by the insulating body 3 itself and thus not visible.
- the cable connection side and the plug-in side of the insulating body 3 are connected to one another via four outer surfaces 34, 31 of the essentially cuboid-shaped insulating body 3 arranged perpendicular to one another, one of these outer surfaces 34, 31 being a PE outer surface 31.
- the insulating body 3 has several contact chambers 32 designed as through-openings for accommodating one of the plug contacts each.
- the contact chambers 32 and the other plug contacts can be of different sizes. Essentially, the other plug contacts - apart from the partially different size - comparable to the PE contact 2 shown previously. The PE contact 2 is therefore one of these plug contacts.
- the contact chambers 32 are aligned in a plug-in direction parallel to the outer surfaces 31, 34 and thus connect the cable connection side and the plug-in side of the insulating body 3 to one another.
- One of the contact chambers 32 is arranged on the PE outer surface 31 of the insulating body 3 and serves to accommodate the PE contact, so that this contact chamber is a PE contact chamber 321.
- the PE contact chamber 321 is open towards the PE outer surface 31 and thus has a PE opening 310 arranged in the PE outer surface 31.
- This PE opening 310 enables the electrical and mechanical contacting of the PE connecting element 1 with the connector housing 5.
- the holding plate 4 has locking means, which are explained in more detail below, for locking onto the insulating body 3.
- the holding plate 4 can have grooved nails.
- the holding plate 4 has an insertion opening 40, 410 for each contact chamber 32, which is arranged on the respective contact chamber 32 for inserting the plug contact into the respective contact chamber 32, 321 when the holding plate 4 is rusted.
- the holding plate has a PE insertion opening 410, which is arranged on the PE contact chamber 321.
- the retaining plate 4 has a locking arm 43 for each plug contact inserted into the contact carrier to prevent rusting of each plug contact, including the PE contact 2. If the retaining plate 4 is rusted on the insulating body 3, the respective locking arm 43 protrudes into the respective contact chamber 32. This allows a cable connection to be inserted into the contact carrier through the respective insertion opening 40 of the retaining plate 4. inserted plug contact in the respective contact chamber 32 on the respective locking arm 43 with its holding collar 23 ver. In particular, the PE contact 2 can rust on its PE locking arm 432 of the holding plate 4 in the PE contact chamber 321.
- the contact carrier consisting of the insulating body 3 and the holding plate 4, is designed to hold the plug contacts to be inserted and/or already inserted in the contact carrier.
- the holding plate 4 and the insulating body 3, when rusted together, are able to hold the plug contacts to be inserted and/or already inserted, in particular the PE contact 2, in the insulating body 3.
- the sliding skids 124 of the inserted PE connecting element 1 engage in these guide slots 3140 and slide along the sliding edge 314 as the PE connecting element 1 slides deeper into the contact chamber. This prevents the PE connecting element 1 from falling out of the insulating body s through the PE opening 310.
- a holding pocket 3260 is arranged on both sides of the plug-side end section of the PE contact chamber 321, which is formed by a holding molding 326 shown above it in the drawing.
- Holding bars 42 pointing in the direction of plugging are arranged. These serve to hold the PE- Connecting element 1 is to be permanently fixed in the PE contact chamber 321 by the retaining webs 42 striking the side walls 12 of the PE connecting element 1 when the retaining plate 4 is secured to the insulating body 3.
- Fig. 4 a and 4 b show the insulating body 3 with the PE connecting element 1 to be inserted from two different perspectives. It is particularly easy to see how the sliding skids 124 engage in the guide slots 3140 and the fixing pins 126 engage in the holding pockets 3260 as soon as the PE connecting element 1 is inserted into the PE contact chamber 321.
- the sliding skids 124 therefore serve to facilitate the insertion of the PE connecting element 1 into the insulating body 3 and to keep the PE connecting element 1 movable in the plug-in direction in the insulating body 3 until the holding plate 4 rusts.
- the sliding skids 124 and the guide slots 3140 can be implemented with very little additional manufacturing effort.
- the PE contact opening 321 has a contact pin opening 3210 for receiving the plug-in area 21 of the PE contact 2.
- Fig. 5 shows the aforementioned parts of the connector insert again in an exploded view, namely the insulating body 3, the PE connecting element 1, the holding plate 4 and the PE contact 2, whereby the PE contact 2 also represents the other plug contacts of the connector insert, which are not explicitly shown here for reasons of clarity.
- the locking means of the holding plate 4 namely the locking tabs 44 with their locking windows 440, can also be clearly seen.
- These serve to rust on the anti-rust means of the insulating body 3, which are designed as locking formations 344.
- These anti-rust means are designed as ramp-shaped locking hooks 344, each with a sliding slope and a holding surface, and are attached to two mutually parallel opposite Outer surfaces 34 of the insulating body 3 are arranged, which are connected to one another via the PE outer surface 31.
- these two outer surfaces 34 with the locking hook 344 formed thereon can be seen, because the other is covered by the insulating body 3.
- This illustration also clearly shows the assembly sequence, in which first the PE connecting element 1 is pushed into the contact chamber 321 of the insulating body 3, then the holding plate 4 is snapped onto the insulating body 3, whereby the PE connecting element 1 is finally fixed in the PE contact chamber 321 of the insulating body 3, and finally the PE contact 2 and the other plug contacts (not shown) with electrical lines connected to them (also not shown), namely crimped, are inserted through the insertion openings 40 of the holding plate 4 into the contact carrier and locked in their respective contact chambers 32.
- FIG. 6 shows a connector having a metallic connector housing 5 with a housing wall 51 and the connector insert in a cross section through the PE connecting element 1.
- the PE contact 2 is not shown in order to allow a clear view of the other components.
- the screw 6 is shown here for the first time, which is screwed from the outside through the connector housing 5 through a threadless through-opening in the housing wall 51 of the connector housing 5 into the screw opening 10 of the PE connecting element 1.
- the screw 6 pulls the base surface 11 of the PE connecting element 1 against the housing wall 51 of the connector housing 5 from the inside with the appropriate screwing force, so that the PE connecting element 1 is mechanically and electrically connected to the connector housing 5 reliably and over a large area.
- the PE contact 2 (not shown here) is secured to the PE locking arm 432 of the holding plate 4 with its retaining collar 23 when it is introduced into the PE contact chamber 321 - coming from the right in the drawing - and is also mechanically and electrically contacted on both sides with the two contact tabs 122 of the PE connecting element 1.
- the arrangement shown is therefore capable of reliably electrically connecting an earthing line crimped to the PE contact 2 both for earthing transfer to a mating connector and to the metal connector housing 5 with only minimal assembly effort.
