Abstract: A protector for use with a circuit board connector having exposed terminals to be electrically connected to terminal pads on an inserted circuit board, the protector partially housing the individual terminals of the connector, thereby to maintain them separated and properly located and insulate them against distortion and damage during handling, shipping, soldering and inserting the circuit board. The protector has walls inserted between contacts, and preferably two cooperating protector halves are utilized, one inserted from each side of the connector.

Abstract: A compliant conductive pin for insertion in and making electrical connection with an internally conductively lined aperture is formed from a screw machine component by conventional machine tool operations; an axial bore is formed in the portion of the terminal to be received in the hole and material is removed from the sides of that portion sufficient to expose the internal aperture, thereby producing a fixed compliant beam in that portion.

Abstract: Either one or two separate skirts may be used as an accessory with an electrical connector part designed to be mounted on a circuit board by a screw or the like. The skirts protect the pins extending from the connector part and facilitate mounting of the connector part to the board. The skirt, designed for mounting on the far side of the connector part, has protruding bushings situated to be received in openings in the connector part and to engage the screws extending from the board such that the skirt and connector part can be mounted to the board as a unit. The second skirt, designed to be interposed between the connector part and the board, may be utilized if pin protection from both sides is required. In this case, both skirts and the connector part are mounted as a unit on the board.

Abstract: A connector block having at least one internally bussed section comprises an electrically insulating housing having top and bottom faces and an electrically conductive buss contact. The housing has exposed on one face a plurality of apertures adapted to receive leads and exposed on an opposite face a plurality of first openings in line and communicating with the apertures respectively and a second opening bridging sides of and communicating with the plurality of first openings. The electrically conductive buss contact is disposed in the second opening and insertable thereinto through the opposite face. The buss contact comprises a body portion disposed in the second opening, a plurality of contact portions resiliently extending from the body portion and into the associated first openings respectively for contact with leads inserted through the associated apertures and associated first openings.

Abstract: A receptacle for a circuit chip having a plurality of exposed connection pads spaced from one another comprises a support body, a plurality of contact members adapted to be associated with the receptacle, a contact-holding element, and a contact-retaining element. Each contact member has a first stop part engaging the receptacle from one direction, thereby limiting the degree to which the contact member can move in that direction, and a second stop part engaging the contact-retaining element from the opposite direction, thereby limiting the degree to which the contact member can move in that direction. The contact-retaining element is removably mounted on the support body so that, after removal thereof, a single defective contact member may be removed from the support body for replacement without disturbing the other contact members.
