Definitions

  • the present invention relates to a connector block comprising at least one contact member in at least one cavity, each contact member being integrally made and provided with a first contact terminal for electrical contact to a contact member of a mating electric element, a second contact terminal and a corrugated spring part giving the contact member a resilient capacity in a predetermined axial direction and being provided with at least a substantially flat middle section.
  • Such a connector block is known from US-A-4,773,877, which discloses a contactor for an electronic tester for testing an electronic device such as printed circuit boards.
  • the known contactor is provided with one or several resilient contact pins, each of said pins having a plunger member and a spring, which plunger member and which spring of each of the contact pins are jointly formed in one piece from a portion of metal sheet.
  • the spring has at least a substantially flat middle section. However, parts of the spring may be folded about folding lines.
  • the spring may have an undulating or meander pattern or a zig-zag-shape. More details regarding this prior art connector block will be given below when figure 3 is explained.
  • the known spring contact member is provided with a sharp contact point which makes the known connector unsuitable for many connecting and disconnecting operations: the sharp contact point would destroy the contact terminal of a mating connector within a very short time period.
  • EP-A-0,009,314 discloses an electrical connector suitable for micro-circuit technology.
  • the connector comprises several connecting elements disposed in rows and columns. Each of the connecting elements is stamped and formed in one piece from sheet metal in strip form.
  • Two identical sinuous portions extend from a strap, the end portions of which function as contact terminals for contacting conductors on e.g. printed circuit boards.
  • the sinuous portions render the contact element resilient in an axial direction.
  • Upper and lower spring sections extend from the strap portion. During operation, the entire connecting element is inserted in a corresponding cavity in the connector body in such a way that contact dimples, provided on the contact terminals are electrically contacting the upper and lower spring sections.
  • the spring sections provide a shorter electrical path than that of the sinuous spring portions.
  • both the sinuous spring portions and the spring sections for providing a short circuit are bent relative to the strap portion. Moreover, the end portions of the sinuous portion are bent to form a U-shape. Thus, these known contact members need many bonding steps during manufacturing and are difficult to be made.
  • This object is obtained by a connector block defined at the outset and characterized in that the first contact terminal of said at least one contact member is provided with a bent extremity.
  • Such a bent extremity establishes a less sharp contact member and enhances the possible number of connecting and disconnecting operations between the connector block and a mating connector.
  • each of the extremities is provided with a dimple to further reduce the sharpness of the contacting end of the first contact terminal.
  • each of the extremities is bent relative to the axial direction through about ⁇ /2 radians.
  • the first contact terminal of said at least one contact terminal may be provided with a rill arranged in the axial direction of the first contact terminal.
  • each of the spring parts extend in a substantially flat surface and are provided with U-shaped or V-shaped interconnected parts.
  • the interconnected parts may be provided with legs and base parts interconnecting the legs, the width (x) of the legs differing from the width (y) from the base parts.
  • the connector block comprises a plurality of said contact members arranged along a line and said flat surfaces are inclined relative to said line.
  • each of the spring parts are provided with U-shaped or V-shaped interconnected parts provided with legs and base parts interconnecting the legs, at least some of the spring parts being folded in such a way that they show a substantially C-shaped or U-shaped cross section seen in the axial direction of the contact members.
  • each of the spring parts are provided with U-shaped or V-shaped interconnected parts provided with legs and base parts interconnecting the legs, at least one pair of adjacent spring parts being folded in such a way that they show substantially C-shaped cross sections seen in the axial direction of the contact members, the C-shaped cross sections being interlaced. Interlacing such C-shaped cross sections supports the object of reducing the size of the connector.
  • each of the cavities are provided with a by-pass strip for reducing the electrical resistance between the first terminal and the second terminal of each of the contact members.
  • Each of such by-pass strips may comprise a metal layer on the inside surface of the respective cavity.
  • a metal layer may be made very thin which further supports the object of miniaturization.
  • the spring part is provided with a part close to the first terminal and is designed in such a way that said part is resiliently forced against the by-pass strip.
  • Figure 1 shows, schematically, a hand-held telephone set known per se and comprising a telephone cradle 1 and a separate housing 4.
  • the separate housing 4 may have any convenient shape, e.g. a large U-shape able to entirely accommodate the telephone cradle 1.
  • the housing 4 may be fixed to a wall, a dash board of a car, etc.
  • the housing 4 is made of any suitable material, e.g. plastic.
  • the telephone cradle 1 can be connected to and disconnected from the housing 4.
  • the telephone cradle 1 is provided with a cradle connector 2 and the housing 4 with a connector block 3.
  • a hand-held telephone set must meet very demanding requirements.
  • the force necessary to connect the telephone cradle to the housing 4 must be as low as possible.
  • the electrical connection between the cradle connector 2 and the connector block 3 must be very reliable, even after very many connections and disconnections: the cradle connector 2 and the connector block 3 must be designed for as many connecting and disconnecting operations as at least ten thousand.
  • the cradle connector 2 and the connector block 3 must be designed as small as possible. Sometimes, fifteen or more electrical connections have to be made.
  • the overall dimensions of the telephone cradle 1 are largely dependent on the dimensions of the cradle connector 2 and the connector block 3. Especially, the pitch distance between neighbouring contact members in the cradle connector 2 and the connector block 3 must be as small as possible. Moreover, the thickness and the width of the cradle connector 2 and the connector block 3 have to be as small as possible. Fourthly, any operator of the telephone cradle 1 must be allowed to connect the telephone cradle 1 to the housing 4 from a bevelled position, i.e. from a position in which the length direction of the telephone cradle 1 does not coincide with the axial direction of the contact members of the connector block 3.
  • the cradle connector 2 cannot simply be provided with female type terminals to receive male type contact terminals 10 (figure 2b) of the connector block 3.
  • the contact terminals 6 of the cradle connector 2 have to be designed in such a way that in the connecting state between the cradle connector 2 and the connector block 3 a sliding contact is provided between the respective contact terminals 6 (figure 2a) and the contact terminals 10 (figure 2b). Therefore, the contact terminals 6 of the cradle connector 2 are usually provided with flat extremities, as shown in figure 2a.
  • the cradle connector 2 and the connector block 3 may be provided with at least one switch coax line for guiding signals which have to be shielded from the outside world.
  • each of the contact members of the connector block 3 have to be provided with a spring action in the axial direction of each contact member.
  • Figure 3 shows a cross section through a connector block 3 along one of the contact members 22.
  • a connector block is essentially known from US-A-4,773,877 albeit for purposes of testing electronic components.
  • the contact member 22 is accommodated within a cavity 24 within the insulating housing 11.
  • the contact member 22 is an integral member comprising a contact terminal 10 for electrical contact to a mating contact terminal 6 (figure 2a), a contact pin 9 to be fixed to a printed circuit board in a manner known to any person skilled in the art and a corrugated spring part 13.
  • the contact member shown in figure 3 is substantially flat and may, advantageously, be made by stamping from a sheet of thin metal, e.g. made of phosphor bronze.
  • the connector block 3 may be arranged in a housing as shown in figure 1. However, the connector block 3 shown in figure 3 may also be accommodated within the housing 14 of a connector connected to a cable 15, as shown in figure 4. There is no restriction as to the location where the connector block 3 of figure 3 may be arranged. Moreover, there is no restriction as to the number of spring contact members 22 within the housing 11 of the connector block 3, or their arrangement within the connector block 3. Like the prior art connector block 3, shown in figure 2b, the connector block 3 according to the invention may be provided with one or more switch coax lines 12 or any other kind of contact members.
  • Figure 5a shows a side view of several legs of a corrugated spring part 13 of a spring contact member 22.
  • the corrugated spring part 13 comprises several adjacent U-shapes, adjacent U-shapes being oppositely arranged.
  • R designates a radius of each U-shape base.
  • Figure 5b and 5c show alternative embodiments of the corrugated spring part 13 of a spring contact member 22.
  • Reference signs X and Y designate the same dimensions as in figure 5a. In the embodiment shown in figure 5b the relation Y > X holds, whereas in the embodiment shown in figure 5c the relation Y ⁇ X holds.
  • Figure 6 shows a functional relationship between said force and the compression distance for some selected dimensions of X, Y, and R.
  • the dimensions given are in millimetres.
  • the relationship shown in figure 6 also depends on the material from which the spring contact member 22 is made.
  • the force necessary to compress the spring contact member 22 is constant, and independent of the compression distance. However, in practice this is not possible.
  • the dimensions of X, Y, and R are preferably chosen in such a way that the force necessary to compress the spring contact member 22 is between 0.2 and 0.4 Newton.
  • Figure 7a shows a further embodiment of a connector block 3.
  • Figure 7a shows a top view
  • figure 7b shows a side view in the direction of arrow P1 in figure 7a
  • figure 7c shows another side view in the direction of arrow P2 in figure 7a.
  • Arrows P1 and P2 are perpendicular to each other.
  • each of the contact terminals 10 is provided with a bent extremity 16 in order to establish a less sharp contact member 10 and to enhance the possible number of connecting and disconnecting operations between the connector block 3 and the mating cradle connector 2 (figure 2a).
  • each extremity 16 is bent through substantially ⁇ /2 radians relative to the axial direction of contact members 22.
  • each of the bent extremities 16 is provided with a dimple 17 to further enhance the possible number of connecting and disconnecting operations.
  • This dimple 17 may occupy a relatively large part of the bent extremity 16 to ensure a smooth and reliable contact with a contact member 6 of a mating connector 2 under many different angles of contacting that mating connector 2.
  • a rill 18 arranged in the axial direction of each contact terminal 10 in order to enforce the rigidity of each of the contact terminals 10.
  • Figure 8a and 8b show two different possible orientations of the spring contact members 22.
  • Both figures 8a and 8b show schematical top views of a connector block 3 having contact terminals arranged along one line L1.
  • the spring contact members 22 have an angle of inclination relative to line L1 smaller than ⁇ /2, whereas in the embodiment shown in figure 8b the angle of inclination between the spring contact members 22 and line L1 is substantially ⁇ /2.
  • the advantage of the embodiment according to figure 8a is that the width W1 of the connector block 3 may be smaller than the width W2 of the connector block 3 in the embodiment according to figure 8b.
  • FIG 9 schematically shows a connector block 3 which is provided with a ground conductor 19.
  • the ground conductor 19 is, during operation, connected to ground, e.g. through a contact pin connected to a ground layer on a printed circuit board to which the connector block 3 is connected.
  • the purpose of the ground conductor 19 is to provide a static discharge capability for selected contact members 22, e.g. those contact members 22 which are connected to (C)MOS circuit parts on a printed circuit board.
  • Figure 10a shows a cross section through the connector block 3 according to figure 9 along line X-X
  • figure 11a shows a cross section through the connector block 3 according to figure 9 along line XI-XI
  • Figure 10b shows an enlarged view of the ground conductor 19 from the cross section of figure 10a
  • figure 11b shows an enlarged view of the ground conductor 19 from the cross section of figure 11a.
  • FIGs 10a and 10b show that each of the contact members 22 may be provided with an extension 21 at the extremity part of the corrugated spring part 13 adjacent to the ground conductor 19.
  • the extension 21 is forced to the extremity of the cavity within the insulating housing 11 of the connector block by the spring action of the corrugated spring part 13.
  • the extension 21 shown in figures 10a and 10b is insulated from the ground conductor 19 by a wall part of the insulating housing 11. Consequently, there is no electrical contact between the extension 21 and the ground conductor 19 and no static discharge capability is provided for.
  • the extension 21 of the contact member 22 shown in figures 11a and 11b electrically contacts the ground conductor 19 when the connector block 3 is not connected to a cradle connector 2 and the extension 21 is forced to the extremity of the cavity within the housing 11.
  • No insulating wall is present between the ground conductor 19 and the extension 21 in figures 11a and 11b. Therefore, any static charge on the contact member 22 in figures 11a and 11b will be conducted to ground through the ground conductor 19 when the connector block 3 is disconnected.
  • Static charges on the contact member 22 of figures 11a and 11b are not able to damage (C)MOS circuit parts on a printed circuit board connected to contact pin 9.
  • the ground conductor 19 in the embodiment shown in figures 9, 10a, 10b, 11a, and 11b is made of a small rod from any suitable metal, e.g. phosphor bronze.
  • a ground conductor strip 19' instead of a rod 19: figures 12a, 12b and 12c.
  • the ground conductor strip 19' may be applied to the inside wall of the insulating housing 11 of the connector block 3 by means of a method for selectively metallization of plastic connectors as described and claimed in European patent application 94202140.3.
  • the ground conductor strip 19' is connected to ground, e.g. on a printed circuit board to which the connector block 3 is fixed, by suitable conductor means (not shown).
  • Figure 12b shows a cross section through a cavity 24 in which the ground conductor strip 19' is exposed to electrically contact part 21 of spring part 13 when the connector block 3 is in its disconnected state.
  • Figure 12c shows a cross section through a cavity 24 in which the ground conductor strip 19' is covered by an insulating layer 25 to prevent electrical contact between the strip 19' and the part 21 of the spring part 13 in this cavity 24.
  • Figures 12a and 12b the latter showing an enlarged view of a construction detail of figure 12a, also show by-pass strips 20 provided on the inside wall of the cavity in which the contact member 22 is accommodated.
  • the ground conductor strip 19' and the by-pass strip 20 are separate from each other and do not contact each other directly.
  • the purpose of the by-pass strip 20 is to electrically contact as many U-shaped bases of the spring contact member 22 as possible and therefore to provide a short circuit for any electrical current through the contact member 22.
  • the application of by-pass strip 20 reduces the electrical resistance between the contact terminal 10 and the contact pin 9 from each of the spring contact members 22.
  • a by-pass strip 20 may be provided at both sides of each of the contact members 22, as shown in figure 12a.
  • one by-pass strip 20 may be provided instead.
  • the by-pass strips 20 may be applied on the inside walls of the cavity by the method for selective metallization of plastic connectors described in European patent application 94202140.3, referred to above.
  • any other method for selective metallization may be used.
  • a metal sleeve may be used, surrounding the spring contact member 22.
  • the corrugated structure of the spring part 13 is, preferably, designed in such a way that the extension 21 is resiliently forced against the by-pass strip 20. Then, as little current as possible is flowing through the spring part 13 itself.
  • the surface part of extension 21 contacting the by-pass strip 20 is preferably rounded and free of any burr.
  • the first part of the corrugated structure opposite to extension 21 may be resiliently forced against by-pass strip 20.
  • a ground conductor 19 or a ground conductor strip 19' is also applicable to any other kind of spring contact member, e.g. the ballpen-type of spring members from the prior art described in the introduction.
  • spring contact member e.g. the ballpen-type of spring members from the prior art described in the introduction.
  • those spring contact members 22 which electrically contact either the ground conductor 19 or the ground conductor strip 19' in the disconnected state will have to be at least slightly compressed in the connected state in order to avoid an electrical connection between the ground conductor 19 or the ground conductor strip 19' and the extension 21 during operation.
  • those spring contact members 22 which have such a static discharge capability may extend slightly more from the body of the connector block 3 with their contact terminals 10 than do the other spring contact members 22 which do not have such a static discharge capability.
  • Figure 13a shows an enlarged view of a spring contact member 22, preferably stamped from a thin metal sheet.
  • Figure 13a further shows two folding lines f1, f2.
  • Figure 13b shows the contact member 22' after such a folding operation which clearly shows that the width of the spring contact member is reduced relative to the width of the spring contact member 22 according to figure 13a.
  • Figure 13c shows a side view of the spring contact member 22' according to figure 13b.
  • Figure 13c shows that the gain in width is at the cost of the space needed in a direction perpendicular to the width direction of figure 13b.

  • the angle of inclination between the C-shaped spring contact members 22' and the line L1 may be varied, as required.
  • Figure 14 also shows an alternative way of bending (or folding) a spring contact member 22 in order to produce an U-shaped spring contact member 22'' (when seen from a top view as in figure 14).
  • the distance between the legs of such U-shaped spring contact members 22'' may be varied, as required.
  • the angle of inclination between these U-shaped contact members 22'' and the line L1 may vary in accordance with the requirements. As explained above, the larger this angle of inclination the smaller the width w1 of the connector block 3 may be.

  • each of the contact terminals 10 of the spring contact member 222 may be provided with a rill 18 and with a bent extremity 16, the latter in turn being provided with a dimple 17.
  • Adjacent bent base parts 23 may be bent in opposite directions, as shown in figure 17b which shows a side view of the spring contact member 222 according to figure 17a.
  • the present invention is not restricted to the embodiments shown in the figures and described above.
  • the connector blocks provided with spring contact members according to the invention are not only applicable in hand-held telephone sets.
