An electrical connector has a flexible printed circuit for interconnecting a mother board and two daughter boards. The electrical connector includes a connector housing that is attached to the bottom of a heat frame that holds the two daughter boards. The connector is secured to the mother board. The flexible printed circuit is looped around a compression plate in the housing and attached to the heat frame and daughter boards at each end by compression assemblies that press gold dot contacts of the flexible printed circuit against the daughter boards.

Solderless electrical connector

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. The jackscrew is rotatably secured to the first connector block within a retainer that is held in place by sandwiching a portion of the connector block between a retainer flange and a securing cap that screws on over a threaded portion of the receiver. The jackscrew in turn has a flange that is lodged between the retainer and the cap to secure it against axial movement, while leaving it free to rotate.

Electrical connector assembly with jackscrew coupling

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.
