An electrical bus strip to receive a terminal post comprises (a) an elongated metallic bus strip; (b) a contact integral with and spaced from said strip, said contact protruding toward a plane defined by said strip, and (c) two pairs of arms having first ends integral with said strip and second ends integral with said contact to support the contact for resiliently yieldable movement normal to said planes in response to insertion of a terminal post into position between the arms of each pair and between the contact and said strip. Typically the bus strip defines an H-shaped opening generally in registration with said contact and arms which were stamped from said strip.

A bridging clip used to interconnect a plurality of electrical terminals which are spaced apart in horizontal rows and vertical columns has incorporated therein a novel positioning means or centering tab. The centering tab provides accurate placement and alignment to avoid problems associated with short circuiting or commoning.

A buss bar for electrically coupling a plurality of electrical terminal posts or wires including a generally tubular elongated body formed of electrical conducting material which defines a slot extending substantially along the entire lateral side of the body, a plurality of holes or apertures arranged in pairs such that one of the holes of each pair is positiond in the upper surface of the body and one of the holes of each pair is positioned in the lower surface of the body to allow one of the terminal posts to be positioned through each of the aperture pairs, a groove or other similar indentation along the opposite side of the body from the slot and extending inward into the center of the body such that the interior surface of the groove is in a position of abutment with a terminal post positioned through the upper and lower holes, the amount of lateral pressure exerted by this interior pressure exerting surface upon the terminal posts being variable proportionally in response to the width of the slot located on the opposite side of the terminal post, the electrical communication being provided by the electrical conducting material from which the body is made and by the secure and efficient electrical connection provided between the terminal post and the three points of contact which are the edges of the upper and lower holes and the pressure surface. The body may also have about the outer surface thereof a coating of electrical insulating material to minimize electrical contact with the surrounding environment.

The present invention relates to contact surfaces on contact elements such as found in card edge connectors and the like. More particularly, the invention teaches a clip slideably mounted on the upper end of a contact element and providing a fixed, tin to tin contact area between the trace on a circuit card and the clip and a gold to gold sliding contact area between the clip and the contact element.

An elongate electrical conductor (2) is disclosed that is adapted for electrically connecting with an electrical contact, the conductor (2) includes a longitudinally extending elongate body (61) for defining a first contact surface (62); and a plurality of longitudinally spaced apart ribs (66) that extend from the body (61) to respective free ends (67) that are spaced apart from the first contact surface (62) for allowing the contact to be progressed between the body (61) and one or more of the ribs (66), each rib (66) including a respective second contact surface (68) that is opposed with the first surface (62) wherein, upon progression of the contact between the body (61) and the one or more ribs (66), the first surface (62) and the respective one or more second surfaces (68) are resiliently biased into engagement with the contact.
