Abstract: Seal retainers for electrical connectors. The seal retainers described herein comprise a retainer plate having one or more slots therein to accommodate a wire or wires leading into a connector. In the retaining position, the retainer plate extends across the connector cavities with the wires passing through the retainer plate slots. A seal and/or secondary lock disposed around the wire in the connector cavities are engaged by the interface of the retainer plate to prevent outward axial movement thereof from the cavities. The retainer plate includes a peripheral flange which fits into a peripheral recess of the connector body and thus lies flush with the connector body surfaces. At least one dovetail tab extends axially from each side of said retainer, said tabs extending from said retainer plate flange. Dovetail recesses in the container body are aligned to receive said dovetail retainer tabs.

Abstract: A combined terminal secondary lock and seal for securing a terminal within a connector cavity in sealed relation comprises a sleeve surrounding the end of the wire and a portion of the terminal and abutting against the widened terminal contact portion. The sleeve includes a plurality of apertures adjacent the insulated portion of the wire, which apertures define a plurality of axially aligned spaced slats sufficient to provide axial rigidity to the sleeve. A resilient seal ring is integrally molded into the apertures and extends outwardly into circumferential sealing engagement with a cavity of the connector and inwardly into circumferential sealing engagement with an insulated portion of the wire. A sleeve retainer is provided on the connector for securing the sleeve and terminal against axial movement.

Abstract: A multi-conductor terminal is disclosed which connects a plurality of discrete electrical connectors without the need for stripping insulation from the conductors.

Abstract: A secondary terminal lock assembly for preventing the removal of an electrical terminal from a terminal block. The lock assembly includes a lock element which is inserted into a terminal block cavity adjacent a conventional female spring locked terminal. The lock element includes a notched locking tongue which engages a locking ear of the terminal block cavity and is held into engagement with the ear by the terminal spring. Shoulders on the locking element prevent withdrawal of the terminal from the terminal cavity. The locking element when properly seated can be seen from the plug side of the terminal block and thus provides a visible indication that the terminal is in a locked condition.

Abstract: A modular construction of an interface board for mounting electrical connectors comprises a plurality of interlocked modular blocks on which the connectors are mounted. Each side face of each block comprises one or more sets of locking elements which engage with a mirror-image set of locking elements on another of said blocks to prevent relative lateral motion between the blocks or structures. Motion of the blocks or structures away from each other, in a direction normal to their mated side faces, is prevented by providing a tapered mortise in each of said side faces, the adjacent mortises of adjacent interlocked blocks or structures being in mutually confronting, aligned relationship to each other so that the tenons of a double dovetail wedge can be inserted into both mortises simultaneously to hold them in fixed position.
