    Abstract: An electrical connector (10) wherein fluid pressure (pneumatics or hydraulics) is used to actuate an expandable bladder (23) located within the housing (11) of the connector to exert force against two flexible circuit members (15, 17) which also might be on the surface of circuit boards, also located substantially within the connector's housing to cause these members to move toward each other and for highly dense arrays of electrical contacts thereon to engage each other in a predetermined manner. A first alignment means (51, 55) is used to provide initial alignment of the two flexible circuit members prior to contact being made. Once such contact occurs, and the expandable bladder is expanded further, the bladder is able to provide additional alignment for the engaged contacts so as to prevent movement thereof relative to each other. Such precise alignment is critical in highly dense arrays of large numbers of small contacts as required in many of today's information handling systems (computers). Once connection is initially made, and expansion of the expandable bladders continues, movement of the engaged flexible circuit electrical contacts is substantially prevented, thus assuring precisioned alignment between these contacts in the overall connector assembly. To prevent abrasion of the expandable bladder during actuation thereof, an interface member (73, 74) is used between the bladder and flexible circuit members, the interface having a smooth, abrasion resistant surface for this purpose.

    Abstract: A compliant portion (3) of the tubular body (2) of a compliant pin (1) is configured with an elliptical cross section (4). Preferably, the tubular body (2) is seamless but alternatively may have a seam with the edges of the seam connected together. The configuration is particularly useful for micro-miniature pins. In the preferred method embodiment, on one side of a member to which the pin is to be affixed, the leading end of a blank tubular pin (1) is inserted into the mating receptacle of the member and such that the blank pin provides a protrusion (12) or extension on the opposite side of the member. A compliant section (3) with an elliptical cross section (4) is formed in a predetermined part of the protrusion and thereafter the pin is partially retracted into the receptacle so that the compliant section coacts with the receptacle to affix the pin to the member.

    Abstract: A fiber optic module connector system comprising a quick connect and disconnect optical terminator having several signal channels and an optically terminated module with a built-in retention system for its mating connector. Fiber optic signal lines are rapidly connected directly to light emitting diodes mounted on an integrated circuit chip in the module.A connector housing (14) contains plural optical terminators (11), each encompassing a fiber optic strand (10). A module substrate (25) has a cap (26) with an opening (29). Plural cones (22), each containing a fiber optic strand (24) from a chip in the module, are attached to the substrate and extend partially through the cap opening (29). A retention housing encompasses the connector housing (14) and enables quick latching of the cones (22) to the terminators (11) by manual actuation of arms (20) which in turn move latching arms (21) into and out of engagement with retention ledges (23) on the module cap (26).

    Abstract: An electrical connector (10) for providing electrical connection to a substrate (19) having contact elements (17) thereon (e.g., a printed circuit board) wherein torsional contacts (13) are utilized. The contacts (13), actuated by a vertically moving, slidable member (41) (e.g., a cam plate) and horizontally moving actuator (51) (e.g., a linear cam), resume a normal, twisted configuration to effect such connection with the respective contact elements (17). Each contact, preferably metallic (e.g., beryllium copper), includes a curvilinear edge segment (35) while each contact element (17) (e.g., plated copper wire) in turn includes a curvilinear contacting surface (105), these two members thus providing a single point form of contact while assuring effective wiping motion to remove undesirable contaminants, debris, etc. which may be located thereon. Relatively high contact forces (e.g., 1.4GPa (200,000 PSI)) are possible using the invention.
