- This invention relates to an electrical connector for the interconnection of individual conductors of an electrical cable to a printed circuit board.
- Electrical connectors exist in the electronics industry having the capability of interconnecting individual conductors of a multi-conductor flat cable to circuit traces of printed circuit boards.

- the cam surface 56 ( Figure 5) is proximate to the lever portion 84 ( Figure 3) such that downward movement of the actuator 50 causes an outward deflection of the lever portion 84 on the cam surface 56, thereby spreading the opposed contact portions 78 and 82 for insertion of the stripped conductors.
- the actuator 50 moves relative to the housing and relative to the wire receiving openings 20.
- the wire receiving openings are not integrated with the actuator such that the wire receiving openings move upwardly and downwardly with the actuator.
- the wire receiving openings are integrated with the actuator and when the actuator is deflected downwardly and the cable is inserted into the wire receiving openings, the release of the actuator tends to push the cable back out of contact with the electrical contacts.
- the present invention has also been designed to accommodate a range of wire sizes, the wire receiving channels 22 are profiled to receive and align conductors of various diameters, as shown in Figures 7 and 8. This has been accomplished by providing a wire receiving channel 22 extending vertically within the side walls 24a, 24b of the terminal receiving cavity 22 as shown in Figures 5 and 7.
- the wire receiving channel 22 first includes radiused sections 22b which are continuous with planar surfaces 22a. As shown in Figure 7, the worst condition of termination is shown where the electrical terminal 70 is right justified within the terminal receiving cavity 24 whereas the conductor C1 is left justified within the conductor receiving channel 22.
- the planar surface 22a positions the conductor by providing a tangent surface to the conductor C1 to prevent the conductor C1 from moving further to the left.
- planar surfaces 22a provide tangent surfaces which are within the radius of curvature of the path formed by arcs 22b. As shown in Figure 7, even with the worst case condition, the electrical terminal continues to have an overlap from the edge of the terminal to the center of the conductor, of a distance L1. Since there is an offset L1, the conductor C1 is mainly gripped between the two opposed contacts 82, 78; rather than relying on the plastic of the housing for a contact force. The planar surfaces 22a are only used for alignment.
- a small conductor C2 having a diameter D2 can also be terminated within the connector again with the surface 22a positioning the conductor within the wire receiving channel 22 with the overlap of the edge of the terminal and the center of the conductor of a distance L2.
- this electrical connector can terminate electrical conductors having diameters which are larger than the thickness of the electrical terminals (t), which allows for a very dense connection system on very close centerlines. Also, since the contacts are edge stamped, as opposed to stamped and formed, the contacts can also be placed on very close centerlines. Since the contacts are edge stamped, the normal force is much higher than a comparably sized stamped and formed terminal.

Abstract
Description
- This invention relates to an electrical connector for the interconnection of individual conductors of an electrical cable to a printed circuit board.
- Electrical connectors exist in the electronics industry having the capability of interconnecting individual conductors of a multi-conductor flat cable to circuit traces of printed circuit boards. These connectors are mounted to the board having electrical terminals exposed at a lower edge thereof which make electrical contact with the traces on the printed circuit board. The electrical connectors also have electrical terminals which accept the conductors in an electrically conducting manner.
- One electrical connector in particular, includes an electrical terminal housing having through passageways for electrical terminals. The housing has a lower face which mounts proximate to the printed circuit board and an upper face which accepts the multi-conductor cable. The terminals are placed in respective passageways within the connector housing, with printed circuit board posts extending beyond the lower face, and cable receiving portions of the terminals disposed proximate to the upper face. The housing also includes a camming member which is moveable to open the cable receiving portion of the terminal, to accept the wire in a zero insertion force fashion. Release of the camming member returns the spring to an undeflected position and into contact with the wire.
- A disadvantage of the above mentioned connector is that the upper face, which includes the conductor receiving openings, is an integral part of the moveable camming member. Thus, to make the electrical connection, the cable is stripped to expose the conductors, and the cam is actuated to open the conductor receiving portions of the terminals. The actuation of the camming member also moves the upper face and the conductor receiving openings, as the conductor receiving openings are integral with the camming member. When the conductors are inserted within the openings, and the camming member released, the spring force actually forces the camming member, including the upper face and openings, upwardly which drives the cable and conductors upwardly also. This reverse spring force could take the conductors out of contact with the terminals when the upper face is moved.
- In the present invention, the electrical connector is characterized in that the upper face of the housing has a plurality of conductor receiving openings therein, the upper face of the housing and the openings being fixedly rigid relative to the camming member. The camming member is moveable relative to the housing and the upper face, whereby, when the camming member is moved to actuate and release the conductor receiving portions of the terminals, the upper face remains fixed relative to the camming member.
- A further object of the instant invention is to design an electrical connector which can accomodate a range of wire sizes.
- The further object has been accomplished by designing an electrical connector of the type for interconnecting a plurality of electrical conductors to further conductive elements. The connector has an insulating housing retaining a plurality of electrical terminals with terminal passageways of the housing, the connector housing having conductor receiving openings therein which are in alignment with conductor receiving sections of the terminals. The connector is characterized in that the conductor receiving openings comprise axially extending passageways comprising arcuate sections contiguous with further surfaces which extend inwardly of the radius of curvature of the arcuate sections, whereby the conductors are aligned towards the center of the passageway by the further surfaces.
- The preferred embodiment of the electrical connector will now be described with relation to the drawings, where:
- Figure 1 is a front plan view of the connector of the subject invention;
- Figure 2 is a top plan view of the connector shown in Figure 1;
- Figure 3 is a cross-sectional view through lines 3-3 of Figure 2;
- Figure 4 is a side plan view of the electrical terminal shown in Figure 3;
- Figure 5 is similar to the cross-sectional view of Figure 3, absent the electrical terminal;
- Figure 6 is an end view of the electrical connector;
- Figure 7 is a cross-sectional view through lines 7-7 of Figure 3 showing a large diameter wire terminated; and
- Figure 8 is a cross-sectional view similar to that of Figure 6 showing an optional smaller diameter wire terminated to the same electrical connector.
- Figure 9 is a cross-sectional view showing an alternate embodiment of the present invention.
- With reference first to Figure 1, the electrical connector of the instant invention is designed for applications where the electrical connector is mounted to through holes in a printed circuit board for electrical connection with a plurality of circuit traces on a printed circuit board. The electrical connector provides easy installation of a multi-conductor flat cable by stripping an end of the insulation which covers the conductors of the cable, and the stripped ends of the cable can be inserted into the wire receiving openings of the electrical connector.
- The subject connector shown generally as 2 in Figure 1 includes an
insulating housing 4 havingside walls 6 and 8 (Figure 3) andend walls electrical connector 2 further comprises an actuator 50 (Figure 2) which is moveable in a downward direction to open the electrical contacts for insertion of the cable conductors. Theelectrical connector 2 further includes a plurality of electrical terminals 70 (Figure 3) having portions which extend below thelower surface 34 of connector for interconnection with printed circuit boards. - With reference first to Figure 5, the
housing 4 will be described in greater detail. Figure 5 is a cross-sectional view through lines 3-3 of Figure 2 excluding theelectrical terminal 70. Thehousing 4 includes a plurality ofwire receiving openings 20 which extend from the upperwire receiving face 16 and extend into theterminal receiving cavities 24. Also shown in Figure 5 is the fact that the conductor receiving opening 20 merges with aconductor aligning channel 22. - With reference now to Figure 7, the detail of the terminal receiving
cavity 24 and thewire aligning channel 22 are described in greater detail, remembering that Figure 7 is a cross-sectional view through lines 7-7 of Figure 3. The terminal receiving channel is defined generally byopposed surfaces arcs 22b andplanar surfaces 22a. It should be noted that theplanar surfaces 22a are inside of the radius of curvature which is formed by thearcuate surfaces 22b. - With reference now to Figure 4, the electrical terminal includes a
horizontal base section 72 which is continuous with avertical base section 74. Extending from thevertical base portion 74 is a first leg 76 which forms anupper contact portion 78. The leg portion 76 is continuous, through abight section 77, with asecond leg section 80 which extends upwardly to form an opposed andsecond contact portion 82. Extending from thesecond leg portion 80 is alever section 84. Extending from thehorizontal base section 72 is a printedcircuit board post 86. - Finally, with reference to Figures 5 and 6, the actuator includes a
horizontal section 52 andarm sections 62 which extend downwardly from thehorizontal section 52. Anaperture 58 extends from theupper surface 52 of the actuator and extends downwardly to form a stop surface 64 (Figure 6). With reference to Figure 1, thehousing end surfaces recessed section 36 having a downwardly facinglatch 38 along a vertical centerline of therecessed section 36. Thelatches actuator member 50. Thelower surface 54 of the actuator in combination with theupper edge 32 of the housing (Figure 5) provide a maximum deflection for the contacts which prevents overstressing the contacts. - To assemble the connector of the instant invention, the plurality of terminals are positioned within the
housing 4 being inserted through theterminal receiving cavities 24 from the lower surface to the connector housing. Theactuator 50 can then be assembled to the connector housing with thearms 62 being inserted into therecesses 36 on eachend wall stop surface 64 rides up over the latch to abut the downwardly facing shoulder of theramp 38. It should be noted that when in this position, the cam surface 56 (Figure 5) is proximate to the lever portion 84 (Figure 3) such that downward movement of theactuator 50 causes an outward deflection of thelever portion 84 on thecam surface 56, thereby spreading theopposed contact portions - It should be noted that the
actuator 50 moves relative to the housing and relative to thewire receiving openings 20. Said differently, the wire receiving openings are not integrated with the actuator such that the wire receiving openings move upwardly and downwardly with the actuator. In some prior art connectors, the wire receiving openings are integrated with the actuator and when the actuator is deflected downwardly and the cable is inserted into the wire receiving openings, the release of the actuator tends to push the cable back out of contact with the electrical contacts. - The present invention has also been designed to accommodate a range of wire sizes, the
wire receiving channels 22 are profiled to receive and align conductors of various diameters, as shown in Figures 7 and 8. This has been accomplished by providing awire receiving channel 22 extending vertically within theside walls terminal receiving cavity 22 as shown in Figures 5 and 7. Thewire receiving channel 22 first includesradiused sections 22b which are continuous withplanar surfaces 22a. As shown in Figure 7, the worst condition of termination is shown where theelectrical terminal 70 is right justified within theterminal receiving cavity 24 whereas the conductor C₁ is left justified within theconductor receiving channel 22. However, theplanar surface 22a positions the conductor by providing a tangent surface to the conductor C₁ to prevent the conductor C₁ from moving further to the left. Furthermore, theplanar surfaces 22a provide tangent surfaces which are within the radius of curvature of the path formed byarcs 22b. As shown in Figure 7, even with the worst case condition, the electrical terminal continues to have an overlap from the edge of the terminal to the center of the conductor, of a distance L₁. Since there is an offset L₁, the conductor C₁ is mainly gripped between the twoopposed contacts planar surfaces 22a are only used for alignment. - As shown in Figure 8, a small conductor C₂ having a diameter D₂ can also be terminated within the connector again with the
surface 22a positioning the conductor within thewire receiving channel 22 with the overlap of the edge of the terminal and the center of the conductor of a distance L₂. - Other advantages of the above mentioned design should be readily apparent. For example, this electrical connector can terminate electrical conductors having diameters which are larger than the thickness of the electrical terminals (t), which allows for a very dense connection system on very close centerlines. Also, since the contacts are edge stamped, as opposed to stamped and formed, the contacts can also be placed on very close centerlines. Since the contacts are edge stamped, the normal force is much higher than a comparably sized stamped and formed terminal.
- Another advantage of this design of electrical connector is that the conductor receiving openings can be alternately formed as shown in Figure 9 such that every other opening is a mirror of the previous one. This places adjacent
planar surfaces 22a in a parallel manner which allows for a thin web of material to interconnect the two adjacent openings thereby allowing for very close side-by-side spacing.
