Abstract:
A card connector is provided for receiving an integrated circuit card. The connector has a connector housing including a metal shell with a slot for receiving the card. A side wall of the shell defines at least a portion of the slot. A spring contact protrudes from the side wall into the slot for engaging an appropriate conductive portion of the integrated circuit card when inserted into the slot. The spring contact includes a proximal bent portion extending angularly from the side wall outwardly beyond the slot. A distal bent portion extends angularly from the proximal bent portion back into the slot for engaging the conductive portion of the inserted circuit card.
Abstract:
An improved termination assembly for multiple grounds of a multi-wire cable is disclosed. The assembly includes a U-shaped retention clip that engages with a termination portion of a ground terminal housed in a connector housing. The clip has at least one notch formed in an edge thereof which is used to locate a drain, or ground, wire in place on the clip in position for soldering the drain wire to the clip. The termination portion may be provided with an opening aligned with one of the notches of the clip so that two drain wires of the cable may be oriented above the signal wires of the cables in similar positions to impose a measure of mechanical uniformity on the termination.
Abstract:
An Improved EMI shield assembly for transceivers is provided in the form of a metal shielding cage that has interengaging cover and base portions. The cover portion has two sidewalls that include leading edges that flare outwardly so that the cover portion sidewalls ride up and over the sidewalls of the base portion. Catches are formed in the base portion sidewalls that have curved surfaces which engage the flared portions to further facilitate the assembly of the shielding cage assembly.
Abstract:
A board to board connector for use in high speed signal transmission applications includes male and female connector components that interengage with each other. Each of the male and female parts has an insulative housing that holds a plurality of individual terminal assemblies in cavities defined by corresponding walls of each connector compenent. The exterior surfaces of the connector components are plated with a metal so as to provide a unitary grounding datum around each of the individual terminal assemblies. Each of the connector components may utilize a center engagement member that runs lengthwise through the connector components, one of the center engagement members having a contact blade formed integrally therewith and the other of the center engagement members including a plurality of spring arms, also integrally formed with the connector component so that the grounding shield portions of the two connectors make contact with each other first before the terminals of the connector make contact.
Abstract:
A shielded floating panel mounted electrical connector includes a dielectric housing having a front mating end and a rear terminating end. The front mating end is designed for mating with a complementary mating connector in a mating direction. A metal shell is mounted about at least the rear terminating end of the dielectric housing. The shell mounts the electrical connector in an opening in and rigidly fixed to a panel. The housing is complementarily engaged within the shell to provide for relative floating movement therebetween in a direction transversely of the mating direction.
Abstract:
A shielded electrical connector is provided for mounting on a printed circuit board. The connector includes a dielectric housing having a plurality of terminal-receiving cavities and a plurality of board-engaging pads projecting from the bottom of the housing. A plurality of terminals are received in the cavities. Portions of the housing between the terminals are plated with conductive metal material to electrically shield the terminals from each other. The plating is continuous onto the pads for connection to appropriate ground circuit means on the printed circuit board. In an alternative embodiment, a shielded electrical connector assembly includes a pair of connectors both of which have plated housings with interengaging plated portions.
Abstract:
The invention relates to a cable connector for shielded data and/or telecommunication cables (10) comprising a shielded housing (20, 48) which shields and surrounds the connector contact (60) for the cable connector and the connector contacts (62) for the leads of the cable (10). The shielding of the cable (10) is extended by means of a single-piece shielding metal sheet (64) on the contact bridge (74) of the cable connector. The screen cover (64) comes into contact with the shielding of the cable (10) by resilient shielding receiving elastic (80).
Abstract:
A connector is formed with a metal shell for use as a shield of the connector. The shell has a pair of tab members formed along its front face that are stamped to provide two metal contact points. These tabs are engaged by metal contact arms formed on a shield of an opposing connector. The metal to metal contact that results from the tab members decreases wear and abrasion and also serves as a conductive connection between the two connector shields.
Abstract:
Disclosed is a plug that comprises: a short current cutoff circuit installed in an electric device and including a cutoff capacitor having a grounded first terminal for restricting the short current; a first plug terminal for receiving AC electricity and supplying electrical energy to the electric device via a wire; a second plug terminal connected to a second terminal of the cutoff capacitor; and a ground check circuit for checking connection states of a ground terminal of an electric outlet with the second plug terminal and including a luminescent element haivng a first terminal connected to the second plug terminal; and a contact terminal connected to a second terminal of to the second plug terminal; and a contact terminal connected to a second terminal of the luminescent element and to be connectable with a human body. Therefore, the plug can remove the EMI via the ground, prevent short states, and checke the connection states of an electric outlet with the plug.
Abstract:
A method for improving the line or point-to-point surface contact resistance of an electrically conductive fiber filled polymer composite (10) includes the laser evaporating of a thin polymer layer from the surface (12) of the composite and exposing of the electrically conductive fiber/particle network (14) underneath. The surface of the composite laser is etched to a depth between about 1 to about 250 microns (about 0.001 mm to about 0.250 mm).
