Definitions

  • This invention generally relates to the art of electrical connectors and, particularly, to a connector housing being adapted to a position assurance system in an electrical connector assembly.
  • the present invention is directed to providing a simple, efficient and cost effective connector housing adapted to an assurance system for electrical connectors of the character described above.
  • a connector housing having only a small number of parts and facilitating mounting of a position assurance system to an electrical connector assembly.
  • An object, therefore, of the invention is to provide a new and improved connector housing adapted to a connector position assurance system in an electrical connector assembly.
  • the invention is defined in claim 1.
  • the housing (24) of the invention being adapted to a connector position assurance system is embodied in an electrical connector assembly, generally designated 10 which includes a first connector, generally designated 12, and a second connector, generally designated 14.
  • the connectors are mateable in the direction of arrows "A".
  • First connector 12 includes a housing 16 defining a receptacle 18.
  • the housing/receptacle is generally rectangular and includes a top wall 16a.
  • a latch boss 20 having a forwardly facing chamfered surface 20a is located generally centrally of and projects upwardly from top wall 16a.
  • a pair of activating bosses 22 also project upwardly on opposite sides of latch boss 20.
  • Each activating boss 22 includes a forwardly facing chamfered surface 22a and a rearwardly facing chamfered surface 22b.
  • a plurality of pin terminals project forwardly within receptacle 18 of first connector 12.
  • Second connector 14 is a plug connector having a portion receivable in receptacle 18 of connector 12.
  • the second connector includes the housing 24 having a plurality of terminal-receiving passages 26 within which are mounted a plurality of female terminals for interengagement with the pin terminals within receptacle 18 of the first connector.
  • a connector position assurance device (CPA), generally designated 28, is slidably mounted on a latching member, generally designated 30, on top of second connector 14. The CPA is movable relative to the latching member in the direction of double-headed arrow "B".
  • housing 24 of second connector 14 is unitarily molded of dielectric material, such as plastic or the like, and latching member 30 is mounted to the top of the housing by a pair of integral pivots 32 which define fulcrums about which the latch member is pivotable in the direction of double-headed arrow "C".
  • a rear end 34 of latching member 30 is accessible by an operators finger so that pushing down on rear end 34 will cause a front end 36 of the latch member to pivot upwardly.
  • a pair of arms 38 extend front-to-rear of latching member 30 and a latch shoulder 40 spans the arms at the front of a slot 42.
  • the latch shoulder is at an elevation below the tops of arms 38.
  • a pair of stop wings 44 project outwardly from arms 38 of latch member 30.
  • CPA 28 includes a central body portion 46 cantilevered from a cross base portion 48.
  • the central body portion has a distal end 50 which defines a blocking tongue, for purposes described hereinafter.
  • a pair of stop arms 52 also project forwardly from cross base portion 48 on opposite sides of central body portion 46.
  • four hooked mounting tabs 54 project downwardly from central body portion 46.
  • hooked mounting tabs project through slot 42 (Fig. 2) in latching member 30 and the hooked portions of the mounting tabs snap beneath the underside of the latching member. Therefore, hooked mounting tabs 54 of CPA 28 received in slot 42 of latching member 30 provide a means for slidably mounting the CPA on the latching member for movement relative to the latching member in the direction of double-headed arrow "B" (Fig. 1).
  • the rear end 34 of the latching member 30 closes off the slot 42 providing a stop for the CPA.
  • Figure 1 shows that the top of the CPA is provided with a serrated ramp 56 to facilitate movement of the CPA, as by an operators thumb or finger.
  • FIGs 4-8 show various sequential positions of first connector 12.
  • second connector 14 latching member 30 and CPA 28 during a mating operation of the connectors.
  • each stop arm 52 of CPA 28 is provided with a downwardly projecting hook 58 at the forward distal end thereof.
  • the hook defines a forwardly facing stop surface 58a, a forwardly and downwardly chamfered surface 58b and a rearwardly facing chamfered surface 58c.
  • Figure 1 shows first connector 12 and second connector 14 in completely unmated condition.
  • Latching member 30 is in its static or inoperative position, and CPA 28 is in its retracted or rear initial inactive position.
  • Figure 5 shows first connector 12 and second connector 14 only partially mated.
  • front end 36 of latching member 30 has moved up chamfered surface 20a of latch boss 20 and is resting on top of the boss.
  • stop wings 44 (Fig. 2) at the sides of the latching member (which are not visible in Figure 5) clear activating bosses 22 of first connector 12 and are not interfered thereby.
  • CPA 28 still is in its rearward or initial inactive position. It should be noted in Figures 4 and 5 that CPA 20 cannot move forwardly because stop surfaces 58a of stop arms 52 will abut against the rear edges of stop wings 44 of latching member 30.
  • This provides a complementary interengaging stop means between the CPA and the latching member to prevent the CPA from moving from its initial position to its final position when the connectors are not mated.
  • FIG. 6 shows first and second connectors 12 and 14 respectively, in their fully mated position.
  • Front end 37 of latching member 30 now has dropped downwardly in the direction of arrow "D”
  • latch shoulder 40 now has dropped behind the abrupt front end of latch boss 20.
  • Figure 7 shows first and second connectors 12 and 14, respectively, still in fully mated condition, and with front end 36 of latching member 30 latched behind latch boss 20 of the first connector.
  • CPA 28 has been moved forwardly in the direction of arrow "E" away from its initial position and to an intermediate position whereat chamfered surfaces 58b at the front end of stop arms 52 have moved over stop wings 44 of the latching member until the hook portions 58 of stop arms 52 have moved onto the tops of stop wings 44.
  • FIG 8 again shows the fully mated condition of first and second connectors 12 and 14, respectively, but CPA 28 has now been moved completely forwardly in the direction of arrow "F” to its final indicating position which indicates that the connectors are fully mated.
  • Stop arms 52 have dropped downwardly in the direction of arrow "G", as hook portions 58 of the stop arms move forwardly of and clear stop wings 44 of latching member 30.
  • CPA 28 In order to unlatch the connectors, CPA 28 is moved back rearwardly opposite the direction of arrow "F" (Fig. 8) to cause rearwardly facing chamfered surfaces 58c of hook portions 58 of the CPA to ride over the tops of stop wings 44 and allow the CPA to move back to its initial position.
  • the front blocking tongue 50 of the CPA moves out of engagement beneath ledge 60, whereby latching member 30 can be pivoted away from its latched position, and the connectors can be unmated.
