  • Patent number: 4746306
    Abstract: An electrical connector has dielectric connector bodies which are coupled and locked together by a resilient lock member of one connector body which snaps past and engages a lock member of the other connector body.The resilient lock member includes a slot which extends through one end and a lock shoulder which faces the opposite end.The other lock member includes a lock shoulder and a loop which passes through the slot of the resilient lock member and cooperatively forms 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 having a shank of substantially the same predetermined minimum size is disposed in the gauge hole to indicate that the connector bodies are locked together by the lock shoulders.

  • Patent number: 4669798
    Abstract: An electrical terminal is attached to a flexible printed circuit by an attachment means which is in the form of a crimp ferrule which comprises an elongated web which has a plurality of raised convex domes which cooperate with sets of crimp tabs integrally attached at the longitudinal sides of the elongated web. These raised convex domes are set in a pattern with respect to the crimp tabs so that the flexible printed circuit is forced to weave through the crimp ferrule when the crimp tabs are curled or crimped over the flexible printed circuit. This establishes several good and stable electrical contacts between the flexible printed circuit and the crimp ferrule and forces the flexible printed circuit to weave through the attached crimp ferrule to provide a strain relief for the several electrical contacts.
