  • Intrinsic certification assembly technique for wiring components into an electrical apparatus
    Patent number: 4050764
    Abstract: A technique is described for completely and positively wiring components into mass produced machines, such as washing machines, dryers and the like. The subject technique encompasses improved contacts, connectors and a wiring harness all of which are individually and collectively adopted to provide a readily ascertainable positive visual indication of a full mating condition and which will prevent further assembly of components if not initially fully assembled in the proper relationship. Each subassembly of a connector and related component includes keying means allowing only correct assembly and mounting in the machine plus visual indicators which verify correct assembly at each step. The connectors preferably have housings which can be produced in great lengths and cut to the desired shorter lengths. These housings also include strain relief means for the associated conductors and may be hermaphroditic.

  • Corrosion-proof electrical connector assembly
    Patent number: 4050766
    Abstract: A housing enclosing an electrical connector has a capable open end through which the connector is received and a closed end having a passage that is sealably mounted in alignment with a through opening in a pressure hull. The connector is isolated from a marine environment by a dielectric liquid that fills the housing and immerses the connector. An end cap closes the open end of the housing to prevent loss and contamination of the liquid and includes a sealable opening through which a first member of the connector is admitted and locked to the housing. A feed-through portion of the connector mates with the cable end portion and is sealably fitted within the passage to provide an electrical connection through the hull. In an embodiment for in-line cable connections, the closed end carries a second member of the connector, corresponding to the first member, which is locked and sealed in the passage.

  • Grip assembly for attaching an electric cord to an electric appliance, and the like
    Patent number: 4036548
    Abstract: A grip assembly is provided for locking an electric cord or cable to an electric appliance, such as a telephone receiver, electric drill, lamp base, or the like. The grip assembly in one embodiment comprises a threaded split bushing which is threaded into the appliance and which surrounds a molded sleeve on the electric cord or cable. The bore of the nut has a surface complementing the outer shape of the sleeve, thereby assuring that the cord will not pull out of the appliance and thus exert a strain on the electrical connections between the wires of the cord and the internal electric elements within the appliance. In a second embodiment the threaded split bushing is supported on the base of an appliance by a nut. The electric cord extends through the sleeve, and when the nut is tightened, the sleeve closes, as a vise, around the cord in a clamping engagement therewith.

  • Adjustable molded hood assembly for a cable connector plug
    Patent number: 4035051
    Abstract: Two protective molded plastic hood embodiments are disclosed that are particularly adapted for use in securing multi-conductor cables to connector plugs of the type typically having one or more arrays of terminals of either the soldered or solderless type associated therewith. Each plastic hood, by having a pressure pad integrally connected to a pressure pad-receiving hood extension formed as an integral rearward portion of the main body of the hood, advantageously allows the composite hood not only to be of one-piece construction, but allows the pressure pad to be key-way guided in a telescopic manner into the hood extension. This insures that reliable, diametrically opposed clamping forces, provided by a cable tie, will always be imparted against a section of cable when positioned between the pad and hood extension, regardless of the diameter of the cable (or cables).

  • Connector cap with cord grip
    Patent number: 4030800
    Abstract: One end of a dead front is nested in and covered by a back plate. The end of a cord may be threaded through a hole in the back plate for connection of its conductors to terminal plates housed in the dead front. Integral with the back plate is means for clamping the cord to the back plate thereby to relieve strain on the connections of the conductors to the terminal plates.The hole in the back plate is defined by an area of the back plate which is segmented and thereby made flexible. Within limits, a cord of a diameter larger than that of the normal size of the hole may be accommodated by forcing the same past the segments and thereby enlarging the hole as required for passage of the cord therethrough.
