Abstract: An electrical connector has a housing and spring contacts. The housing has uniform straight, cross-sectional T-shaped contact receiving slots. The spring contacts have middle sections fixedly mounted to the housing in head sections of the T-shaped slots and top sections. The top sections have contact areas deflectably located in base sections of the T-shaped slots and pre-load tabs movably confined in the head sections of the T-shaped slots.

Abstract: An electrical connector for mechanically and electrically connecting a mother printed circuit board and a removable daughter printed circuit board of the card edge connection type. The connector has a housing with a slot for receiving an edge of the daughter board and two rows of contact chambers for receiving and holding individual contacts therein. The connector also comprises a plurality of a first type of contact having a contact area formed from a bulging bight having a coined contact surface, the curve of the bight and the curve of the crown producing a compound radii.

Abstract: A connector adapted to be attached to a mother printed circuit board and to removably receive a daughter printed circuit board of the edge card type and adapted to mechanically and electrically couple the mother and daughter printed circuit boards, the connector comprising an electrically insulating housing; and a plurality of electrically conductive contacts extending through the housing in rows of spaced pairs for removably receiving an edge of a daughter printed circuit board in a central plane between the rows, each contact including a lower section formed as a solder tail positionable to depend from the housing for coupling with the mother printed circuit board; an intermediate section extending upwardly from the solder tail and inwardly toward the central plane for supporting a received daughter printed circuit board; and an upper section extending upwardly and outwardly to define, at the bight of the upper and intermediate sections, a contact area of compound radii configuration on the radially exterio

Abstract: A receptacle includes a square tubular plastic body member closed at its bottom and open at its top and having formed in the corners of its upper border inwardly projecting locking barbs provided with downwardly inwardly inclined upper cam surfaces and bottom horizontal locking edges. An integrally formed closure assembly includes a square frame having a depending skirt wall telescoping the body member top border and having recesses formed in its corners receiving corresponding barbs and having bottom shoulders engaging the barb bottom edges, the frame having a top peripheral flange abutting the body member top edges. A lid is self hinged to the frame and includes a skirt wall engaging the frame flange in the lid closed position and depending corner elements engaging the frame corner recesses. Cooperating latching elements are provided at the free edges of the frame and lid.

Abstract: This invention relates to tools for installing a connector body on the ends of cable conductors, wherein an indentor head is caused to impinge upon a connector positioned within a compression head to cause connector member to be indented to a desired depth; the device being adaptable to accommodate connector members of varying diameters and to adjust automatically the depth of indentation according to the diameter of the connector being compressed, through operation of differential thread mechanisms connected to a rotatable handle shaft.
