Electrical connector lock with gauge pin

Claim 2

In an electrical connector having dielectric conenctor bodies which are coupled and locked together by a deflectable lock member of one connector body which snaps past and engages a rigid lock member of the other connector body, the combination comprising: said deflectable lock member including a cantilevered arm having a slot which extends through a fire end of the cantilevered arm and a lock shoulder which is in the slot and faces toward an opposite end of the cantilevered arm, said rigid lock member including a loop which has one end insertable into the slot of the cantilevered arm and a lock shoulder which faces an opposite end of the loop, said loop having a portion disposed in the slot of the cantilevered arm and cooperatively forming a gauge hole of predetermined minimum size with the deflectable lock member when the connector bodies are coupled and locked together by the lock shoulders, and a gauge pin having a shank of substantially the same predetermined minimum size disposed in the gauge hole, to indicate that the connector bodies are locked together by the lock shoulders and to prevent deflection of the deflectable lock member and consequent disengagement of the lock shoulders.

Claim 3

In an electrical connector having dielectric connector bodies which are coupled and locked together by a deflectable lock member of one connector body which snaps past and engages a rigid lock member of the other connector body, the combination comprising: said deflectable lock member including a cantilevered latch arm and a sloping tab at a free end of the cantilevered latch arm, said latch arm having a slot which extends through the free end of the latch arm and which has a narrow portion extending from the free end to provide a lock shoulder which is in the plane of the latch arm, said tab having a slot which communicates with the narrow portion of the slot in the latch arm, said rigid lock member including a lock projection and a loop which extends outwardly of the lock projection, said loop having a narrow end portion which is insertable into the narrow portion of the slot in the arm and the slot in the tab and a wide end portion which provides an abutment for the tab of the cantilevered arm and a lock shoulder which faces an opposite end of the lock member, said lock projection having a lock shoulder which faces the wide portion of the loop, said narrow end portion of the loop passing through the slots of the arm and the tab and cooperatively forming a gauge hole of predertermined minimum size with the resilient lock member when the connector bodies are coupled and locked together by the lock shoulders, a gauge pin having a shank of substantially the same predetermined minimum size disposed in the gauge hole to indicate that the connector bodies are locked together by the lock shoulders, and said gauge pin having means for retaining the shank in the gauge hole.

Claim 4

In an electrical connector having dielectric connector bodies which are coupled and locked together by a deflectable lock member of one connector body which snaps past and engages a rigid lock member of the other connector body, the combination comprising: said deflectable lock member including a cantilevered latch arm and a sloping tab at a free end of the cantilevered latch arm, said latch arm having a slot which extends through the free end of the latch arm and which has a narrow portion extending from the free end to provide a lock shoulder which is in the plane of the latch arm, said tab having a slot which communicates with the narrow portion of the slot in the latch arm, said rigid lock member including a lock projection and a loop which extends outwardly of the lock projection, said loop having a narrow end portion which is insertable into the narrow portion of the slot in the arm and the slot in the tab and a wide end portion which provides an abutment for the tab of the cantilevered arm and a lock shoulder which faces an opposite end of the lock member, said lock projection having a lock shoulder which faces the wide portion of the loop, said narrow end portion of the loop passing through the slots of the arm and the tab and cooperatively forming a gauge hole of predertermined minimum size with the resilient lock member when the connector bodies are coupled and locked together by the lock shoulders, a gauge pin having a shank of substantially the same predetermined minimum size disposed in the gauge hole to indicate that the connector bodies are locked together by the lock shoulders, and said gauge pin having means for retaining the shank in the gauge hole.

Claim 5

In an electrical connector having dielectric connector bodies which are coupled and locked together by a deflectable lock member of one connecotr body which snaps past and engages a rigid lock member of the other connector body, the combination comprising: said deflectable lock member including a cantilevered latch arm and a sloping tab at a free end of the cantilevered latch arm, said latch arm having a slot which extends through the free end of the latch arm and which has a narrow portion extending from the free end to provide a lock shoulder which is in the plane of the latch arm, said tab having a slot which communicates with the narrow portion extending of the slot in the latch arm, said rigid lock member including a lock projection and a loop which extends outwardly of the lock projection, said loop having a narrow end portion which is insertable into the narrow portion of the slot in the arm and the slot in the tab and a wide end portion which provides an abutment for the tab of the cantilevered arm and a lock shoulder which faces an opposite end of the lock member, said lock projection having a lock shoulder which faces the wide portion of the loop, said narrow end portion of the loop passing through the slots of the arm and the tab and cooperatively forming a gauge hole of predetermined minimum size with the resilient lock member when the connector bodies are coupled and locked together by the lock shoulders, a gauge pin haivng a shank of substantially the same predetermined minimum size disposed in the gauge hole to indicate that the connector bodies are locked together by the lock shoulders, and means for guarding against jamming and locking the shank in spaces other than the gauge hole,

Claim 6

In an electrical connector having dielectric connector bodies which are coupled and locked together by a deflectable lock member of one connecotr body which snaps past and engages a rigid lock member of the other connector body, the combination comprising: said deflectable lock member including a cantilevered latch arm and a sloping tab at a free end of the cantilevered latch arm, said latch arm having a slot which extends through the free end of the latch arm and which has a narrow portion extending from the free end to provide a lock shoulder which is in the plane of the latch arm, said tab having a slot which communicates with the narrow portion extending of the slot in the latch arm, said rigid lock member including a lock projection and a loop which extends outwardly of the lock projection, said loop having a narrow end portion which is insertable into the narrow portion of the slot in the arm and the slot in the tab and a wide end portion which provides an abutment for the tab of the cantilevered arm and a lock shoulder which faces an opposite end of the lock member, said lock projection having a lock shoulder which faces the wide portion of the loop, said narrow end portion of the loop passing through the slots of the arm and the tab and cooperatively forming a gauge hole of predetermined minimum size with the resilient lock member when the connector bodies are coupled and locked together by the lock shoulders, a gauge pin haivng a shank of substantially the same predetermined minimum size disposed in the gauge hole to indicate that the connector bodies are locked together by the lock shoulders, and means for guarding against jamming and locking the shank in spaces other than the gauge hole,

Claim 7

said means comprising integral wings spaced from the cantilevered latch arm near its attachment end, a forwardly projecting, U-shaped flange on the sloping tab, and an integral narrow rib behind the lock projection.

Claim 8

said means comprising integral wings spaced from the cantilevered latch arm near its attachment end, a forwardly projecting, U-shaped flange on the sloping tab, and an integral narrow rib behind the lock projection.
