Abstract: An electrical component is packaged in an insulator housing which has insulation displacement terminals and operating members to facilitate field assembly to insulated conductors. The operating members are integrally connected to a hinged over of the housing by frangible webs and forced down into the body to connect the insulated conductors to the insulation displacement terminals.

Abstract: An insulation displacement terminal comprises a base having a pair of integrally connected side plates and an integrally connected flex arm disposed between the side plates. The side plates have guide grooves formed in part by inwardly staggered legs. The flex arm has laterally spaced plates which bias an insulated conductor received in the guide grooves against the edges of inwardly staggered legs of the side plates to establish a four point electrical contact with the core of the insulated conductor under the constant pressure of the flex arm.

Abstract: A cooperating primary and secondary lock means used in combination with a pair of matable electrical connector bodies both assures that the connector bodies have reached the fully mated position, and double locks them together. Keeper projections on a cantilevered primary locking arm of the first connector body are engaged by the camming end of a rotatable secondary locking arm on the second connector body. This pulls the connector bodies together, if they were not fully mated, and as the camming end snaps beneath the keeper projections, full mating is indicated. The secondary locking arm thereby also captures the primary locking arm to provide a double lock.

Abstract: A three-piece fuse block assembly for an automotive vehicle comprises a bracket attached behind the front wall of the vehicle instrument panel, a fuse block hinged to the bracket for movement between a horizontally stored position and a vertically access position, and a manually operable latch attached to the fuse block for releasing the fuse block from the stored position and pulling it down to the access position.
