Definitions

  • This invention relates to an electrical contact.
  • the majority of known electrical contacts have a mating portion adapted to mate with only a single type of mating contact in a single possible orientation.
  • some pieces of electrical equipment for example automobile headlamp bulbs, have a plurality of contacts, for example male tabs, arranged in different orientations, for example in mutually perpendicular planes, and thus an electrical connector for mating with such an array of contacts must when using known contacts either use two different forms of contact, or use only one form of contact but in different orientations.
  • Patent Specification DE-A-1 465 461 there is disclosed an electrical contact having a contact portion comprising two pairs of opposed cantilever contact arms all extending in the same direction, each arm of each pair presenting a contact projection to a similar projection on the opposed arm, the two pairs of opposed arms defining a common male-contact-receiving slot.
  • This known contact is designed to mate with either a flat tab or a round pin male contact which is engaged by the four contact projections on the arms of the contact, which thereby provide four independent points of contact on the inserted male contact, in known manner.
  • this known contact does not have a slotted-plate conductor connection portion, and thus there is no difficulty in mounting the contact in any desired orientation to receive a male contact.
  • This known contact is therefore not in any way adapted to mate with a male contact in other than one orientation, that is with the male contact being engaged by the contact projections on the arms of the contact.
  • US-A-1 508 474 discloses a plug socket adapted to receive a circular contact member or flat contact member in either of two orthogonal orientations.
  • the socket contact is formed from a blank folded to define opposed slotted arms each of which is arcuately formed in section to define a circular section contact receiving cavity bounded by four contact arms, edges of each arm being reversely curved to define between adjacent arms, flat blade receiving spaces of parallel sided form.
  • This known contact is adapted for wire connection at the folded portion by a wire clamping screw.
  • each arm of each pair presents a second contact projection opposed to a similar contact projection on the adjacent arm of the pair, the two pairs of opposed second contact projection defining, at the aligned slots, a second male-contact-receiving slot, the fold extending transversely of the first contact receiving slot and being formed with a wire receiving slot extending transversely of the fold to define bridging portions at either side of the wire receiving slot and between the cantilever arms, the wire
  • Such a contact portion gives the advantage that a plurality of the contacts of the same form can be mounted in a common housing in the same orientation, this making connection of conductors to the conductor connection portions of the contacts easy when the conductor connection portions are slotted plates, to provide a connector capable of being mated with an array of male tab contacts in which the tabs are arranged in mutually perpendicular planes, such as is found on automobile headlight bulbs.
  • a substrate such as a printed circuit board can be mated with the contacts.
  • the contact shown in Figures 1 and 2 is stamped and formed from sheet metal, and comprises a conductor connection portion 1 and a contact portion 2.
  • the portion 1 comprises two similar plates 3 and 4 arranged in spaced parallel planes, the plates being joined by two bridging strips 5 and 6 extending between the plates 3 and 4 from adjacent edges thereof.
  • Each plate 3 or 4 has a slot 7 therein, and since the slots 7 are similar only one thereof will be described in detail with particular reference to Figure 1.
  • Each slot 7 has a mouth 8 at the edge of the plate from which the bridging strips 5 and 6 extend, the bridging strips 5 and 6 being on opposite sides of the mouth 8.
  • the mouth 8 leads to a first inwardly tapering section 9 having converging straight sides, which in turn leads to a second parallel straight sided section 10.
  • a first inwardly tapering section 9 having converging straight sides, which in turn leads to a second parallel straight sided section 10.
  • the sides of the second section 10 are bevelled to provide relatively sharp cutting edges.
  • the second section 10 leads into a third inwardly tapering section 11 having convex converging sides leading to a throat 12.
  • the throat 12 opens into a short fourth outwardly tapering section 13 the walls of which constitute shoulders facing away from the throat 12.
  • the fourth section 13 leads into a fifth inwardly tapering section 14 having convex converging sides, the maximum width of the fifth section 14 being less than that of the third section 11.
  • the fifth section 14 terminates in an enlarged circular aperture 15 which serves in known manner to determine the resiliency of two arms of the portion 1 defining the slot 7.
  • an insulated conductor having a core formed from a plurality of strands is urged transversely of its axis into the slot 7 through the mouth 8.
  • the first section 9 guides the conductor into the second section 10, the sharp edges of which cut through the insulation of the conductor, possibly up to the core thereof depending upon the size, that is the diameter, of the conductor.
  • the conductor then enters the third section 11 of the slot 7, the walls of which section 11 complete the cutting of the insulation of the conductor if necessary, and also apply a gradually increasing compressive force on to the core of the conductor while guiding the core to the throat 12.
  • the core then at least partially passes through the throat 12 into the fourth and fifth sections 13 and 14 of the slot 7, the walls of the fourth section 13 engaging over some of the strands of the core to retain the core in the slot 7.
  • Figures 3 to 6 diagrammatically illustrate a slot as described above having four different sizes of core therein, the core size increasing from Figure 3 to Figure 6. It can clearly be seen that in each case the core is engaged under the shoulders formed by the sides of the fourth section of the slot, with the strands of the core being compressed between the sides of the third and fifth sections of the slot, thereby to establish an electrical and mechanical connection between the core and the contact member containing the slot.
  • the contact shown in Figures 1 and 2 contains two slots as described above, and for termination a conductor would be urged into the two slots simultaneously thereby to establish connection to the conductor at two spaced locations, in known manner.
  • the conductor is preferably urged into the slots by means of a tool which is preferably part of a connector assembly comprising an insulating housing in which the contact is mounted, and an insulating cover which serves to urge the conductor into the slots and then remain secured to the housing covering the cpnnection between the contact and the conductor.
  • the cover is preferably formed with a stuffer member which serves to engage the conductor to urge it into the slots as necessary, and which remains in contact with the conductor in the final assembly, serving to retain the conductor at the required position in the slots in the contact. Since conductors of different size must be urged to different depths in the slots, the size of the stuffer member would be set. in dependence upon the size of conductor to be terminated.
  • the two slots in the contact are of mutually different width over their second, third and fourth sections 10, 11 and 13, the slot in the rear (in Figure 1) plate being narrower than that in the front plate over these sections.
  • Such a contact is usable with a relatively wide range of conductor sizes since it is ensured that at the ends of the range at least one of the slots will give a satisfactory connection while over most of the range both slots will give a satisfactory connection.
  • the contact portion 2 of the contact shown in Figures 1 and 2 comprises two opposed pairs 20 and 21 of resilient contact arms 22, each arm 22 presenting a first rounded contact surface 23 to the opposed arm 22 of the other pair, and presenting a second rounded contact surface 24 to the other arm 22 of the same pair.
  • the two pairs of opposed first contact surfaces 23 define a first slot into which a substrate such as a printed circuit board or a male tab contact can be inserted for connection to the contact, while the two pairs of opposed second contact surfaces 24 define a second such slot into which a similar substrate or male contact can be inserted, the first and second slots thus defined being mutually perpendicular.
  • the free ends of the arms 22 of each pair 20 or 21 are bent to provide a flared mouth 25 for the first slot defined by the first contact surfaces 23.
