Abstract: An electrical connector (20) has a dielectric housing (22) defining a mating face (26) and a mounting face (58). The housing (22) has a plurality of terminal receiving passages (30) extending from the mating face with terminals (32) secured therein. An eletrically conductive shell (36) has a shroud portion (44) that encircles the mating face (26) to engage shielding of a complementary shielded connector and to shield the terminals (32) secured in the housing (22). A tab (48) extends from the shell (36) to interengage with a ground strap (52) and secure the ground strap (52) to the connector (20). A ground path is thereby completed from the shell (36) through the tab (48) then the ground strap (52), and possibly a securing means (92), to a ground pad (118a;118b) on a printed circuit board (120) on which the connector (20) is mounted.

Abstract: The present invention is directed to a multi-pin coax connector assembly having connector housings made of metal or conductive plastic which serves as a reference ground for all signals. The connectors have passages extending therethrough. Pin and socket terminals are insert molded with insulating material and are positioned in the passages. The insulating material spaces the terminals from the conductive connector housing as well as providing air gaps along most of the length of the terminals. The air gaps cooperate with the insulating material to provide controlled impedance. As the signals travel at a high rate of speed along the terminals, the terminals are bent to minimize the reflection of the signal. The connectors are provided with power and ground busses along the outside surfaces thereof, the busses of the first connector making electrical connection with the respective busses of the second connector.

Abstract: Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more filtered connector inserts releasably mounted within an outer conductive shell. A plurality of filtered contact assemblies are releasably retained within the insert. Each filtered contact assembly includes an electrical contact, a filter electrically coupled to the contact, and a first grounding means electrically coupled to said filter. The filtered contact assemblies are releasably and electrically coupled to the insert when the assemblies are releasably mounted to the insert, and to the outer shell when the insert is mounted within the shell. With the invention, a grounding path is automatically provided from the filter associated with each filtered contact assembly to the outer shell to dissipate filtered interference, while allowing individual removal and replacement of each filtered contact assembly from the insert, and removal and replacement of each insert from the shell.

Abstract: A metal clip is described which retains a modular insert containing an insulator body with contacts thereon, in a shell of a connector, while also providing a ground plane and shield against electromagnetic interference. The clip includes a flat middle portion that extends across most of the width of the connector and a pair of opposite ends bent out of the plane of the middle portion and having edges that abut shoulders formed on the shell and that press against shell surfaces lying adjacent to the shoulders. The flat middle portion lays facewise against a face of the insulator body of the connector to prevent movement of the insulator body and contacts therein. The middle portion of the clip spans most of the area within the shell to provide an electromagnetic shield that is electrically terminated to the shell.

Abstract: A device which supports a shaft rotatably in an electrically grounded frame. The shaft is mounted in bearings in the aperture of an electrically conductive molded member mounted on the frame. A grounding brush is secured to the molded member and electrically connects the shaft with the molded member so as to electrically ground the shaft.

Abstract: A grounding system for cabinets containing electronic equipment is made up from vertical bars (2), horizontal bars (3) and connection bars (11) between the horizontal bars, all the bars being made of aluminum. At the connection points between the bars there are mounted contact-making, spring-biased contact plates (4). The contact plate (4) is rectangular and provided with contact tongues (6) arranged in rows projecting from, both faces of the plate.

Abstract: A pressure sealed grounded potential bushing in cable fittings which is charged with pressurized gas such that the bushing has a lead-through opening in which an access pressure safety device is mounted so as to prevent excessive pressure. A valve includes a seat and spring arrangement such that the valve opens under excess pressure by moving against the bias of the spring.

Abstract: A coaxial cable connector a body of which has, on one surface, a receptacle including first and second terminal members for electric connection thereto of an end plug of a coaxial cable and, on other surfaces, means for mounting the connector, in common, to a generally used mounting frame for house wiring modules, to be contributive to simplification of house wiring works and prevention of any deterioration of the electric connection.

Abstract: An insulating bolt is disclosed herein for use in supporting signs on walls comprising a hollow threaded shaft having a channel disposed on the shaft to receive a grounding strap which is laid in the channel. The end of the grounding strap conforms to the end of the shaft of the bolt for engaging into the end of an armored cable thus providing grounding means from the sign back to the power source. A slide locking nut having a raised shoulder for sliding in the channel is provided for positioning and holding the bolt in place.

Abstract: A grounding mechanism for an electrical connector having a metal generally U-shaped spring contact mounted on a cylindrical rubber or neoprene connector body which is connected directly to the internal ground contact within the connector body. Resilient tips on the body act to bias the free ends of the spring contact outwardly. The free ends of the spring contact stay in contact with a rotatable collar mounted over the body due to the compressed nature of the pre-formed metal spring contact, as well as the radially outward force of the resilient connector body tips acting on the free ends of the spring contact.

Abstract: An electrical connector comprises a dielectric housing having terminal passages in which electrical terminals are secured. A metal shell is secured onto the housing and ground contact means is provided for achieving electrical contact with the metal shell and a ground plate on a circuit board, the ground contact means including spring means for urging contact members of the ground contact means into electrical engagement with the ground plate.

Abstract: Modular electrical connector assemblies and filtered connector inserts therefor. The assembly includes one or more connector inserts removably mounted within an outer shell. The filtered insert comprises a housing means, at least a portion of which is electrically conductive; at least one electrical contact within the housing means; and filter means within the housing electrically coupled to the contact for filtering interference, and electrically coupled to the conductive housing portion for providing a grounding path from the filter means to the conductive housing portion. Means are also provided for electrically coupling the conductive housing portion of the insert to the outer shell automatically when the insert is positioned in and mounted to the shell to provide an external grounding path from the conductive housing portion to the shell.

Abstract: A mechanism for locking the connection between a first electrical connector having a first insulating housing with contacts arranged therein and a conducting connector case surrounding said insulating housing and a second electrical connector having a second insulating housing with contact arranged therein. It comprises a locking member extending along at least one side of said first electrical connector between said insulating housing and said conducting case; a first connection member fitted between said insulating housing and said locking member for protecting said locking member against physical damage and electronic equipment against electrostatic damage; a second connection member provided on the insulating housing side of said second electrical connector corresponding to said first connector side on which said locking member and the connection member are mounted.
