  • a hooked latch projects inwardly from cross portion 58, and a pair of outwardly opening locking grooves 58b are formed in the outside surface of cross portion 58 to form locking shoulders.
  • a pivot hole 60 is formed in each latch or lever arm 56 for receiving a respective latch post 52 projecting outwardly from housing 32.
  • the hole has a radially extending cut-out portion 60a for receiving hook 52a of pivot post 52. Therefore, latching lever 14 can be mounted to housing 32 only by aligning hooks 52a of pivot post 52 with the cut-out areas 60a of pivot holes 60.
  • FIG. 5 shows that latching lever 14 is pivotable in the direction of double-headed arrow "C" about pivot posts 52 from a preliminary mating position shown by full lines and a latched or fully mated position shown in phantom, as will be described in greater detail hereinafter.
  • plug connector 16 includes a dielectric housing, generally designated 66, which may be a one-piece structure molded of plastic material.
  • the housing includes the terminal-receiving passages 26 which receive socket terminals 22 (Fig. 3).
  • a pair of first guide grooves 70 in a top portion of the housing receive the first guide ribs 42 of the receptacle connector.
  • a pair of second guide grooves 72 in a bottom portion of housing 66 receive the second guide ribs 44 of the receptacle connector.
  • An enlarged third guide groove 74 receives the third guide rib 36 of the receptacle connector.
  • a cam follower projection or latch post 76 projects outwardly from each opposite side of housing 66.
  • Each latch post has a shank portion 76a and an enlarged head 76b.
  • a locating detent notch 76c is formed in the latch post and faces in the mating direction of the connector.
  • An elongated guide rib 78 extends rearwardly from latch post 76 in the mating direction.
  • a pair of locking member locating walls 80 project upwardly from housing 66 of plug connector 16 for receiving or locating locking member 18 (Fig. 6) in a position shown in FIG. 8.
  • a locking member coupling structure is disposed between locating walls 80.
  • the coupling structure includes a locking hole 84 having chamfered first locking shoulders 84a at opposite sides thereof. Another side of the hole defines a latching shoulder 84b. Second locking shoulders 86 are formed near the bottom of locating walls 80.
  • locking member 18 includes a body 90 which may be a one-piece structure molded of plastic material.
  • the body includes a pair of locking projections 92 which extend forwardly in the mating direction.
  • a pair of first mounting hooks 94 project downwardly from the body, and a pair of second mounting hooks 96 also project downwardly from the body but outside first mounting hooks 94.
  • a pair of coupling grooves 98 are formed on the underside of body 90, one groove 98 being disposed outside each first mounting hook 94 and inside the respective second mounting hook 96.
  • Locking member 18 is mounted to the top of plug connector 16 in the direction of arrow "D" in FIG. 8.
  • first mounting hooks 94 on the underside of the locking member snap into latching engagement with the chamfered first locking shoulders 84a (Fig. 7A) of coupling structure 82.
  • Second mounting hooks 96 snap into locking engagement with second locking shoulders 84.
  • Grooves 98 on the underside of the locking member receive coupling projections 100 which project upwardly from coupling structure 82.
  • the plug connector is inserted into receptacle 40 of the receptacle connector, as the cam follower projections or latch posts 76 on the outsides of the plug connector are inserted into guide slots 48 in side walls 50 of the receptacle connector.
  • Precise guiding of the plug connector into the receptacle connector is effected as follows: (1) first guide ribs 42 of the receptacle connector move into first guide grooves 70 of the plug connector, (2) second guide ribs 44 of the receptacle connector move into second guide grooves 72 of the plug connector, (3) third guide rib 46 of the receptacle connector moves into third guide groove 74 of the plug connector and (4) elongated guide ribs 78 which trial behind latch post 76 on the plug connector ride into guide slots 48 of the receptacle connector.
  • the elongated guide ribs 78 prevent the two connectors from relative movement in a vertical direction and prevent relative pivoting movement about horizontal axes generally perpendicular to the mating direction. This entire guide means system ensures that the connectors are aligned precisely and, in turn, precisely aligns socket terminals 22 of the plug connector with pin terminals 20 of the receptacle connector.
  • Separate locking member 18 then is used to completely lock the latching lever in its mated position. This is accomplished by mounting the locking member onto the plug connector in the direction of arrow "D" in FIG. 8, and as described above. When the locking member is so mounted, locking projections 92 of the locking member are positioned in locking grooves 58b of the latching lever so that the latching lever cannot move back out of its final position of mating of the connectors.
  • hooked latch 58a and latching shoulder 84b form a preliminary latch means for mating assist lever 14.
  • Locking member 18 forms a final locking means for the mating assist lever.
  • the preliminary latch means is engaged automatically when the mating assist lever reaches its fully mated position.
