摘要:
An interface for connecting coplanar printed circuit ("PC") boards (10, 20) using a flexible jumper circuit (50) for bridging the PC boards (10, 20), a base (80) underlying the second PC board and integrally attached thereto, and a support housing (30) with compression plugs (60) which may be tightened against base (80) for securing the two PC boards (10, 20) and for compressing the flexible jumper circuit (50) against the two PC boards (10, 20). The interface is precision aligned by a plurality of guide pins (34) which protrude from support housing (30) and conform to guide holes in the two PC boards (10, 20) and the flexible jumper circuit (50). Guide pins (34) fix the relative positions of the boards (10, 20) and circuit (50) within their respective planes. The resilient compression plugs (60) maintain contact between the flexible jumper circuit (50) and the two PC boards (10, 20) despite irregularities in thickness, and the guide pins 34 maintain precision horizontal alignment between the contact pads (12, 22) on the two PC boards (10, 20) and the conductive traces (52) on the flexible jumper circuit (50).
摘要:
The invention is directed to an electronic docking connector for edge mounting an electronic device, such as a daughter board, to a mother board. The connector comprises a pair of housing members assembled to define an elongated slot planarly aligned with the edge of the mother board. Mounted therein is a pair of opposed force applying, resilient spring members operatively mounted for receiving and applying a compressive force against the electronic device. A flexible film member, containing electrical circuitry thereon, is also mounted within said housing members for electrically interconnecting corresponding circuitry on the mother board, and the electronic device. As an alternative, a dielectric insert is disposed between each spring member and its corresponding flexible film to reduce or eliminate cross talk therein.

A unitary heat sink and connector housing (10, 10', 10", 10"') is disposed between a pair of electrical members, such as printed circuit boards (11, 12, 31) and/or flexible etched circuits (32) in an overall assembly used in a variety of high-performance miniaturized electronic products. One or more flexible electrical connectors (21, 25, 26, 29, 30) are mounted within the unitary heat sink and connector housing (10, 10', 10", 10"') and provide a circuit interface between respective circuit elements or pads (13, 14) on the printed circuit boards (11, 12, 31) and/or flexible etched circuits (32), respectively. The unitary heat sink and connector housing (10, 10', 10", 10"'), which preferably has heat-radiating fins (20), is made from a material which is thermally conductive but electrically non-conductive. Examples of such a material are anodized aluminum, silicon dioxide and beryllium oxide. Any suitable ceramic material could be used.

A flexible electrical connector (16) provides a circuit interface between the bent leads (12) of an integrated circuit package (10) and the respective circuit pads (14) of a printed circuit board (15). The integrated circuit package (10) is mounted on the surface of the printed circuit board (15), and the circuit interface has a substantially zero insertion force therebetween. The flexible electrical connector (16) has closely-spaced circuit traces (17) carried by an elastomeric core (18). The traces (17) accommodate the fine pitch of the leads (12) on the integrated circuit package (10); and the elastomeric core (18) provides a resilient "cushion" which compensates for irregularities or tolerance accumulations in the bent leads (12) as well as the different lead-bending specifications of the respective integrated circuit manufacturers.
摘要:
The invention hereof relates to electronic apparatus, such as a computer docking connector. More particularly, the invention relates to a docking connector for edge mounting to a "mother" board, where a "daughter" board, memory card, or similar device is inserted into said connector to electrically interconnect the mother board to the inserted device. The apparatus comprises a pair of spring biased, hermaphroditic, resilient housing members, which when assembled define an elongated slot planarly aligned with an edge of the mother board. Opposed camming surfaces are provided with the slot to operatively spread the housing members upon insertion of the electronic device int the slot. Finally a flexible film member containing electrical circuitry thereon is mounted within the housing members for electrically interconnecting corresponding circuitry on the mother board and the electronic device.

A connector body (10 10', 10") is mounted on a mother board (11) and has a compressible electrical connector (15). A daughter board (22) is slidably inserted into the connector body (10, 10', 10") perpendicularly of the mother board (11). A deflection means (34, 56) engages a side of the daughter board (22) and deflects the daughter board (22) away from the compressible electrical connector (15) to prevent damage thereto after the daughter board (22) is slidably inserted. When the daughter board (22) is fully inserted, a retaining means 28, 43, 69) exerts a lateral clamping force on the daughter board (22).
摘要:
A docking assembly including a guide housing (2) and camming assembly (38, 54 and 40) for mechanically interfacing a modular component (46) with a circuit board to thereby complete and protect multiple electrical connections therebetween. An interfacing connector (80) is also disclosed for providing an electrical and mechanical interface between a circuit board and a disk drive (82). The interfacing connector (80) allows high-density multiple electrical interconnections to the circuit board by the use of canted coil springs (100) for direct electrical contact with individual traces and/or contact pads on the circuit board. The interfacing connector (80) may also include a docking assembly (130) with guide channels (136) for guiding insertion of a circuit board to thereby insure the integrity of the electrical interconnections therebetween.

An anisotropic interposer pad (10) disposed between a first surface (11) and a second surface (12) in an electrical interface wherein the interface surfaces (11, 12) are non-compatible metals. The interposer pad (10) is a plastic layer (20) and a plurality of spaced-apart electrically conducting particles (21) are disposed in a random pattern throughout the plastic layer (20). The particles (21) extend between the first side (22) of the plastic layer (20) and the second side (23) of the plastic layer (20). There is no lateral contact between any of the particles (21). The particles (21) are electrically conductive in a direction oriented between the first side (22) and the second side (23) of the plastic layer (20). The particles (21) act as an electrical connection between the first surface (11) and the second surface (12).

In one embodiment, the wires (14) are solder coated (16) with a solder reflow effecting a tab to wire connection and in another embodiment, precious metal coatings are employed to allow pressure connection between wire and traces. Alternatively, coatings of conductive inks or conductive adhesives may be used. The conductive traces may be placed on centers appropriate to the particular centers in the array of conductive pads and in the array of wires, such centers being selectively varied.
