Patent number: 6190214Abstract: A novel press-fit electrically-conductive contact member, as, for example, an electrically-conductive metal pin, characterized by a conforming section which has an elastically-deformable region which acts as a spring and which is adapted to engage a substrate hole in a press-fitting relationship. The conforming section comprises opposed beam members configured to accommodate a considerably larger hole tolerance yet still provide sufficient retention force to stabilize the pin during a soldering process that such substrates may typically undergo. The beam cross-sections are configured to allow them to occupy a side-by-side position. Contact members with the conforming section can be manufactured by a wire-forming process in which end-to-end connected pins are formed as a continuous strip needing no excess material for carrying the pins, nor are any air gaps formed between the pins, and thus the finished continuous strip of pins can be wound up on a reel.Type: GrantFiled: December 7, 1999Date of Patent: February 20, 2001Assignee: Autosplice Systems, Inc.Inventors: Giuseppe Bianca, Robert M.

A plurality of linking strips (11) engages with each first half (1211). A guiding tape (10) engages with the linking strips (11) so that each linking strip (11) is connected between the first half (1211) and the guiding tape (10). A coining step to round the edge of compliant portions (1223) is to be carried out. The attachment of the guiding tape (10) to the linking strips (11) rather than to the free ends (123) of the compliant pins (122) facilitates such coining step.Type: GrantFiled: December 22, 1998Date of Patent: February 13, 2001Assignee: Hon Hai Precision Ind.

Patent number: 6159049Abstract: An electrical connector having a housing that includes a conductive piece and a plastic piece, electrical contacts mounted to the housing, and a circuit assembly connected to the contacts. The circuit assembly comprises circuit elements and a lead frame. The lead frame is formed from a bandolier used to carry the contacts and the circuit elements prior to insertion into the housing. One portion of the lead frame may form a ground plane and may be joined to the conductive housing piece. Bandolier index holes may be used for attaching the ground plane portion to posts on the conductive housing piece. An uncut section of the lead frame may form a bridge for grounding a contact. The lead frame may also be mounted onto a ferrite block.Type: GrantFiled: December 7, 1998Date of Patent: December 12, 2000Assignee: Framatone Connectors Interlock, Inc.Inventors: Stephan H.
