Abstract: An improved shielded and insulated electrical connector for terminating shielded multiconductor cable is formed by a pair of mating metal shield members which engage a peripheral metal shell means on a standard connector and enclose the rear conductor exiting portion thereof. The shield members each include embossed strengthening means as well as interengaging side walls to completely enclose the rear of an electrical connector. At least one shield member is provided with at least one overmolding pressure relief means which opens at a predetermined pressure and allows a limited amount of overmolding insulating material to enter the cavity defined by the shield members while equalizing the inner and outer shield member pressures. The shield members also include gripping means which allow overmolding insulative material to enter and harden thereby becoming fixedly attached to the shield members to prevent withdrawal due to shrinking as the overmold insulative material cools.

Abstract: An improved shielding assembly for an overmolded electrical connector is formed by a pair of mating metal shell members which engage a peripheral metal housing of a standard connector and enclose the rear conductor exiting portion thereof. The shell members each include embossed strengthening means as well as interengaging side walls to completely enclose the rear of an electrical connector. The shell members are each further provided with overmolding pressure release means which opens at a predetermined pressure and allows a limited amount of overmolding material to enter the shell members while equalizing the inner and outer shell member pressures. The shell members also include gripping apertures which allow overmolding material to enter and harden thereby becoming fixedly attached to the shell members to prevent withdrawal due to shrinking as the overmold material cools.

Abstract: Stamped and formed electrical terminal has a conductor-receiving portion comprising parallel plate-like members having aligned conductor-receiving slots. The terminal has a transition portion intermediate the ends thereof and has a contact portion extending from the transition portion. The transition portion comprises first and second sections which extend from the plate-like members. Each section has an arcuate cross section part adjacent to the plate-like member which fairs into a part having a U-shaped cross section. The contact portion comprises one or more arms that extend from at least one of the U-shaped parts. In one embodiment, each U-shaped part has two contact arms extending therefrom which are resiliently biased against each other to provide contact force on a complementary terminal when the two terminals are coupled.

Abstract: A connector of a type used with dry cell batteries comprises an insulating support having a snap fastener plug terminal and a snap fastener socket terminal on one surface thereof. The support has terminal supporting projections on its one surface and the terminals are stamped and formed sheet metal members. The terminals are partially inserted through the support so that the external contact portions of the terminals are against the terminal supporting projections and the internal or second contact portions of the terminals are on the reverse surface of the support. The connector can be used as a closure for the jacket of a 9-volt battery. A manufacturing method for the connector is also disclosed.

Abstract: Zero insertion force connector clip assembly for connecting conductors on a flexible film to conductors on a circuit board comprises a stamped and formed metallic clip and a lifting tool mounted on the clip. The clip has cantilever springs extending from one of its side edges towards the surface of the circuit board. The springs are arcuately formed to define bearing portions which bear against the circuit board conductors and each spring has a portion extending from the bearing portion towards the clip bar. Each spring also has a tool engageable section which extends substantially parallel to the clip bar. The lifting tool comprises a platelike member mounted against the clip bar having edge portions disposed between the end portions of the spring and the clip bar. The springs can be raised from the surface of the circuit board by manipulating the tool as a lever to raise the bearing portions of the springs so that a cable can be inserted beneath the bearing portions.

Abstract: Slotted plate terminal comprises two wire-receiving portions, each having an inner plate-like member with a wire contacting slot therein and an outer plate-like member with a strain relief slot therein. Slots extend inwardly from bights which connect each inner plate-like member to an adjacent outer plate-like member at the wire receiving end. Inner plate-like members are connected by a web opposite the wire receiving end. Outer plate-like members have extensions which extend toward each other then laterally of the web to form a mounting portion. The terminal may be mass produced in strip form. Means for mounting and wire insertion are disclosed.

Abstract: Connecting means comprises an electrical terminal and a housing having a terminal-receiving cavity therein. The terminal is a flat one-piece sheet metal device having two integral four-bar linkage mechanisms thereon arranged symmetrically with respect to an axis extending medially through the terminal. The connecting or floating links of the linkages are adjacent to the axis, the fixed links are relatively remote from the axis, and the crank links extend diagonally between the fixed and connecting links. When a wire is positioned between the connecting links and the two four-bar linkages are deformed by applying deforming forces to the ends of the connecting links, the connecting links move laterally towards each other and clamp the wire between their opposed surfaces.

Abstract: A method of terminating coil windings is disclosed in which the ends of the coil wire are wound around posts which are integral with the bobbin prior to and, at the conclusion of, the coil winding process. The bobbin is provided with terminal-receiving cavities located such that the ends of the coil wire extend from the posts across these cavities. Electrical connections to the ends of the coil wire are made by cutting off the posts and thereby severing the wire at a location adjacent to the post and inserting terminals into the cavities which establish contact with the ends of the coil wire. The lead wires can then be connected to the same terminals.

Abstract: A crimped electrical connection between a stamped and formed metallic connecting device and a conductor on an insulating film comprises a pair of opposed cantilever beams connected by an arcuate bight with the film being between the beams. The beams are in a flexed condition against the film and are therefore maintained against, and in electrical contact with, the conductor on the film. The crimped connection can be used under a wide variety of circumstances.

Abstract: Electrical connections for conductors on two spaced apart films are provided by means of a strip of connecting devices. The strip comprises a carrier strip with the connecting devices extending therefrom at spaced intervals. Each connecting device has first and second side-by-side crimp portions, each crimp portion being generally U-shaped. The connecting devices are crimped onto the two films by positioning one film between the arms of the first connecting devices of a section of the strip and the second film between the arms of the second connecting devices. The connecting devices are then crimped onto the film and the carrier strip is removed. A housing for the connecting devices is also disclosed.

Abstract: A coil bobbin is disclosed which has means for facilitating electrical connections of the coil wire to external conductors. Improved coil winding and manufacturing methods are also disclosed. The coil bobbin has two contact receiving cavities extending into one of its flanges and has integral binding posts for the wire extending from the flange. Wire positioning means are provided for locating the coil wire with its axis extending from the binding posts in crossing relationship to the cavities and then to the coil supporting surface. In use, the wire is wrapped around one of the posts, passed through one of the cavities, and is then wound on the coil supporting surface. After the required number of turns have been wound, the wire is passed through the other cavity and wrapped around the remaining post. Terminals are inserted into the cavities to establish contact with the wire and the posts are cut away from the bobbin flange.

Abstract: Stamped and formed connecting device for splicing a small diameter lead wire to a larger diameter resistor core comprises a U-shaped connecting member having a web and sidewalls. The web has a semicylindrical central depression for the lead wire and has arcuate portions on each side of the depression which conform to the resistor core. The sidewalls are reversely folded at their outer ends to provide inner and outer layers. The ends of the inner layers are located adjacent to the depression. In use, the lead wire is located in the depression, the resistor core is positioned between the sidewalls, and the sidewalls are crimped onto the resistor. The ends of the inner layers move relatively towards, and against, the lead wire during crimping and establish contact with the lead wire. Contact with the resistor core is established by the inner surfaces of the inner layers of the sidewalls.
