Definitions

  • An electrical conductor assembly which includes a pair of mating members which have an open first position and a closed second position; a pair of passageways in the assembly; a pair of cam surfaces in the assembly and a chamber adjacent the cam surfaces when the members are in the second position; a flexible conductor mounted in each of the passageways and extending a distance beyond the end of its passageway greater than the length of the cam surface; the flexible conductors when the mating members are in closed position extending into the chamber and having a primary and a secondary axis; the cam surfaces being in line with the primary axis of the conductors when the mating members are in the first and second positions; and said conductors being in engagement with each other when the mating members are in the second position; and the end of each conductor when the mating members are in the second position having their secondary axis different from their primary axis and parallel to and spaced from the primary axis.
  • This invention relates to electrical connectors and more particularly to electrical connectors of the hermaphroditic and cam type having positive pressure connector means therein.
  • Another object of this invention is to provide a connector which uses a double wipe and double contact connection.
  • a further object of this invention is to provide a connector assembly which has improved vibration and shock reliability.
  • Still another object of this invention is to provide an electrical assembly in which the parts which mate are identical requiring therefore only one master die to produce both mating parts.
  • Yet a further object of this invention is to provide an electrical assembly which can be used to simultaneously cause connection of a number of pairs of conductors.
  • Another object of this invention is to provide an as- United States Patent 3,461,258 Patented Aug. 12, 1969 'ice sembly having a reciprocating member which permits ready connection and disconnection.
  • Still a further object of this invention is to provide a connector assembly having cam surfaces which individually cause connection between twoor more conductors.

  • FIGURES 7, 8 and 9 illustrate additional modifications of this invention in cross section showing various cam surface assemblies
  • FIGURES 10 and 11 illustrate in cross section still further modifications of the invention showing hermaphroditic assemblies.
  • FIGURE 12 is a sectional view illustrating another modification of this invention.
  • FIGURES 1 THROUGH 3 The assembly as generally shown in FIGURE 1 is comprised of a pair of hermaphroditic housings 10 and 12 which as illustrated in FIGURE 1 are generally rectangular in configuration.
  • the housings are made of some nonconductive material which may be molded or cast or otherwise formed as illustrated.
  • Coupling members 14, 16, 18 and 20 project forwardly of the housing and have locking ribs or beads 22, 24, 26' and 28.
  • the coupling members 14 and 16 and 18 and 20 are laterally spaced relative to each other as best illustrated in FIGURE 1.
  • the locking ribs 22, 24, 26 and 28 engage in slots such as 30 and 32.
  • Leads 34 and leads 36 are crimped to conductors 38 and 40.
  • a conductor 38 which is identical with conductors 40 shown in FIGURE 2 is provided with clamping members 42 which are crimped or otherwise formed around the leads 34 and 36 to insure positive electrical connection.
  • the leads 34 and 36 would be stripped if necessary.
  • the method of connecting the leads to the conductor 38 does not form a part of this invention as this may be done by any means such as crimping, soldering, and the like.
  • the conductor 38 includes a smooth flat blade 44 which is quite flexible so that the blade may be bent or flexed in various planes.
  • the blade 44 has struck from it a tine 46 for purposes of locking the conductor in the housing 10 or the housing 12 as the case may be.
  • the conductor 38 is also provided with centering arms 48 for positioning the conductor in the passageways 50 and 52 of the blocks or housings 10 and 12 respectively.
  • the passageways 50 and 52 are relieved as at 54 and 56 to provide clearance means for the locking tine 46.
  • the passageways are further relieved by clearance spaces 58 and 60 which receive the ends of the blades 44.
  • the housings 10 and 12 are provided with cam surfaces 62 and 64 respectively.
  • the flexible conductors extend a distance beyond the end of their respective passageways greater than the length of the cam surfaces 62 and 64. It should be further noticed that the flexible conductors when in mated position have primary and secondary axes. The main body of the conductor lies along the primary axis and the end of the conductor lies along the secondary axis. The two axes are parallel and spaced from each other in the configuration illustrated in FIGURE 2. The intermediate portions of the conductors in the areas of a cam surfaces 62 and 64 show gaps 66. It will be obvious that the action in the closing of the two housings and 12 causes a double wiping action of the conductors by the ends of the conductors resulting in a two point contact connection.
  • One point of contact for a pair of conductors is in one housing and the other point of contact for the same pair of conductors is in the other housing. Due to the action of the earns 62 and 64, a bowing occurs in the conductors towards each other as will be obvious from a study of FIGURE 2. This bowing action is possible due to the flexing of the blades of the conductors 38 and 40. In the device illustrated in FIGURES 1 through 3, the relieved portions or clearance spaces 58 and 60 are slightly larger than the thickness of the blade 44 of the conductors 38 and 40. This insures a good firm contact between the conductors.
  • the blades 44 of the conductors 38 and 40 are non-configured and lie flat. As aforementioned, the blades when the housings 10 and 12 are in mating position assume an S-shaped configuration.
  • FIGURES 4, 5 AND 6 the housing 68 is provided with a plurality of parallel conductors 70 mounted in passageways 71 therein in spaced relation.
  • a mating housing 72 is provided with a series of outer tines 74 and inner tines 76. All of the tines are provided with cam surfaces 78.
  • a spaced pair of conductors 70 which are aligned with two face to face cams 78 will come together as best shown in FIGURE 5 when the housing 68 is mated with the mated housing 72.
  • a pressure contact 80 is made by the two conductors being cammed together when the housings are mated.
  • the conductors may be mounted in the housing 68 in any conventional fashion. The spacing between the tines should be sufficient to permit a contacting pair of conductors 70 to slide thereinto Without difficulty.
  • Locking snaps 82 are provided to engage recesses 84 for maintaining the housings 68 and 72 in mating position.
  • the housing 86 holds a button or plunger 88.
  • a spring member 90 is provided for maintaining the button or plunger in extended position within the housing 86.
  • the spring member 90 may be of resilient material such as plastic or may be a coil spring or the like.
  • Outer tines 92 and inner tines 94 are provided on the button 88 and have cam surfaces 96 which operate on the conductors 98 in a manner similar to that illustrated in FIG- URE 4.
  • the conductors 98 are mounted in passageways 99 in housing 86.
  • the button or plunger 88 may be positioned in the housing 86 by snapping the button therein around the shoulders 100 of the housing 86. Any other conventional arrangement for insertion of the plunger 88 in the housing 86 may be provided.
  • the pairs of conductors 98 will have primary and secondary axes similar to the structure shown in FIGURE 2 when in mating position.
  • FIGURE 7 is a slightly different modification of the invention in which the conductors 102 are mounted in passageways 103 in the housing 104 and are cammed in the same direction by a cam surface 106 in the mating housing 108.
  • the conductors 102 have their ends in overlapping relationship as illustrated in FIGURE 7.
  • the cam surface 106 is in line with the primary axis of the conductors 102.
  • FIGURE 8 shows a slightly different modification of the invention illustrated in FIGURE 7 and includes two cam surfaces 110 and 112 in the mating housing 114 which abut each other and run in opposite directions. Certain of the conductors 116 will run in one direction Whereas others will run in the opposite direction as noted in FIGURE 8.
  • the mating housing 120 is shown with three cam surfaces 122, 124 and 126.
  • Cam surfaces 122 and 124 run in the same direction whereas cam surface 126 runs in the reverse direction. It is noted that cam surfaces 124 and 126 form a depression rather than an apex as in FIGURE 8.
  • the conductors 128 overlap each other in a manner similar to that described with regard to FIGURE 7.
  • the conductors 102, 116, and 128, have a primary and secondary axes when the housings are mated.
  • the secondary axis in FIGURES 7 through 9 of the conductors is at a diagonal with the primary axes.
  • the conductors In order to function properly, the conductors must be quite flexible, relatively thin, smooth and unconfigured when in non-mating position. This provides the best possible pressure contact action when the housings are mated.
  • FIGURES l0 and 11 In FIGURE 10, the hermaphroditic housings 130 and 132 are provided with cam surfaces 134 and 136. The cam surfaces, run rearwardly from the passageways 138 and 140. It is to be noted that the bows 142 and 144 of the conductors 146 and 148 respectively extend back only to the forward edge of the mounting passageway cam surface.
  • FIGURE 11 is substantially similar to FIGURE 10 but includes recessed areas 150 and 152 which permit the bow of the conductors 154 and 156, mounted in passageways 153, to extend back into the mounting passageway beyond the forward edge of the passageway cam surfaces 158 and 160.
  • stops 162 in FIGURE 10 and 164 in FIGURE 11 are provided to prevent further forward travel of the conductors when the housings are mated.
  • the conductors 142, 144 and 154 and 156 extend beyond the end of their respective housings a distance farther than the greatest depth of the passageways in the opposite conductor in the areas of their cam surfaces. This causes buckling of the conductors toward each other as illustrated in FIGURES 10 and 11, in order to provide a good pressure contact between conductors. It will be obvious, from a review of the material, that multiple pairs of conductors can be used in housings provided with multiple passageways operating in a manner similar to the structures shown in FIGURES l0 and 11.
  • FIGURE 12 the housing 166 receives the housing 168.
  • a chamber 170 is formed by the housings when in closed position.
  • Blades 172 are mounted in passageway 174 and are shown flexed inwardly by cam surfaces 176 against blades 178 which at all times lie in a single plane and have only one axis in open or closed position as compared to the blades 172 which in open position have a single axis but in closed position have two spaced and parallel axis A and B with a diagonal axis C.
  • a separator 1'80 separates conductors or blades 178.
  • Latches 182 maintain the housings in mating position.
  • a hermaphroditic electrical assembly comprising:
  • each housing having a flexible conductor mounted in its passageway and when assembled extending into the passageway of the other housing and having a primary and an offset secondary axis
  • each housing having a cam surface on its passageway in line with the primary axis of the conductor mounted in the other housing and deflecting the end of the conductor mounted in the other housing in a direction toward and into engagement with its own conductor, and
