摘要:
A seal processing station for a modular harness making machine comprises a seal sorting and feeding unit (10) and a seal insertion unit (8). The seal sorting and feeding station comprises a container (20) that has top and bottom chambers (22, 24) where seals provided in a loose form are blown by means of an air channel (28) from a bottom of the container to a top of the container. The seals fall through a cutout (44) that separates the chambers onto a vibrating feed track (14). The seals are fed to a seal insertion unit (8) that has an insertion device (66) comprising concentric axially movable pins (70, 72, 74) that insert the seal (S) over a wire end (W) that remains stationary and clamped to the seal insertion unit by grippers (60, 62). The seal sorter is particularly slim and has a simple and reliable seal feeding device for compact installation in a modular harness making machine. The seal insertion unit (8) avoids axial movement of the wire during insertion of seals. The wires can be conveyed along a conveyor system by grippers (90) that may have a relatively simple construction because the wires do not need to be moved in the axial direction by the grippers (90).

A cable connection arrangement is provided wherein the braids (108) of a plurality of coaxial cables (100) are soldered to a grounding member (30), and the signal conductors are covered by inner insulators (110) and which extend forward beneath the grounding member (30). Ground plates (32) are formed on the grounding member (30) so that these ground plates (32) protrude from one edge of the ground member (30). The ground plates (32) and inner insulators (110) are offset from each other by approximately one-half pitch. The ground plates (32) and the signal conductors are connected at the same time by press fitting into terminals (20a and 20b).

摘要:
An electrical receptacle connector assembly (4) for application to a printed circuit board consists of an insulating housing (6) and spring contacts (8) received in cavities (9) in the housing. The cavities are T-shaped having a portion that is substantially rectangular, constant cross section from a contact receiving face (12) of the housing (6) up to a position proximate to a mating face (10) of the housing and a contact retention slot (15) along one side thereof. Each spring contact (8) consists of a forward leaf contact spring (32), an intermediate retention portion (33) with retention ears (48), and a rearward contact tail (34) for soldering to a conductor on the circuit board. In each cavity (9) the retention portion (33) and a flat end portion of the leaf spring (32) lie flat against one face (24) of the cavity (9), the leaf spring being bowed towards the opposite face (26) of the cavity, with the retention ears (48) biting into surfaces of slots (15) and the contact tail (34) projecting from the contact receiving face (12) of the housing (6). The housing and the spring contacts are simple and economical to manufacture and the spring contacts are easy to load into the cavities. The contact tails can be configured for various modes of mounting the assembly on the circuit board.
