  • Patent number: 5405270
    Abstract: An electrical connector assembly includes two connector blocks that are coupled together by means of a jackscrew on one block that is screwed into a receiver on the other block. The jackscrew and receiver are formed from metal, while the remainder of the connector blocks are formed from a lower cost and lighter weight plastic. The receiver is held in place within a securing member in the second connector block, with the receiver and securing member having complimentary outer and inner polygon surfaces to keep the receiver from rotating. Axial receiver movement is prevented by a boss on the securing member that extends into a recess in the receiver, while the securing member is held against axial movement between a flange on one side and a securing cap on the other.
    Type: Grant

  • Patent number: 5213512
    Abstract: An electrical connector device (10) is provided in which a first member (15) of dielectric material defines a four-sided recess having a bottom wall (20) and side walls (16), and a second member (24) of dielectric material which can fit inside the recess with its edges (25) spaced a predetermined distance from the side walls (16) of the first member (15). Tab portions (31, 32, 44, 45) of one or more flexible circuits (11, 12) are bent around the side walls (16) of the first member (15) and frictionally held between the wall (16) of the first member (15) and the edge (25) of the second member (24). Exposed conductors (29, 49) of the flexible circuit (11, 12) on the outside of the wall (16) can mate with conductors (75) in a socket connector (13). Alignment means (19, 26, 73) are provided to align the flexible circuits (11, 12) with the members ( 15, 24) of dielectric material and to align the latter two members and frictionally hold them together.
