Abstract
Abstract The present invention relates to an interconnect device to provide electrical connections between printed circuit boards or a supported flexible circuit board and a wire wrap connection or solder tail connection or the like. More specifically the preferred embodiment of the invention includes a device, stamped and formed from a coplanar strip of conductive material and having a double thickness leg on top of which is an elongated spring arm formed into a rectangular shape to reduce the height it occupies in a housing while providing high spring force. Additionally, stress-distribution means is incorporated into the device.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
146 words
A device for providing an electrical interconnect between diverse electronic components, comprising: a. a lower section comprising a leg for insertion into a board or the like or about which a wire may be wrapped; and b. an upper section connected and positioned perpendicularly to the lower section and having a connecting strap and an elongated spring arm which includes a first portion extending obliquely from said strap, a second portion connected to the first portion and extending in a direction parallel to the strap, a third, elongated portion connected to and extending at right angles to the second portion and a fourth portion connected to the third portion and extending back towards the leg, said fourth portion being the free end of the spring arm and having a contact thereon adapted to engage a conductive trace on a generally rigid circuit board or the like.
Claim 2
Independent Claim
146 words
A device for providing an electrical interconnect between diverse electronic components, comprising: a. a lower section comprising a leg for insertion into a board or the like or about which a wire may be wrapped; and b. an upper section connected and positioned perpendicularly to the lower section and having a connecting strap and an elongated spring arm which includes a first portion extending obliquely from said strap, a second portion connected to the first portion and extending in a direction parallel to the strap, a third, elongated portion connected to and extending at right angles to the second portion and a fourth portion connected to the third portion and extending back towards the leg, said fourth portion being the free end of the spring arm and having a contact thereon adapted to engage a conductive trace on a generally rigid circuit board or the like.
Claim 3
Dependent Claim
49 words
The device of claim 1 further including support member extending from the connecting strap towards the free end of the spring arm and preloaded downwardly, said support member adapted to transfer and distribute compressive stresses which may be exerted against a housing in which the device may be placed.
