KR910002047A - Circuit panel sockets with clover contacts - Google Patents

Abstract

A single in-line memory module socket employing edge stamped contacts positioned within an insulative housing is disclosed. Each terminal has opposed beams with a loop section intermediate the ends of upwardly extending portions of those beams. Inwardly inclined arms extend downwardly from the top of the opposed beams and the contacts are configured so that majority of the deflection of the beams occurs in these inwardly inclined arms. A central post extends upwardly from the base of the terminals and engages housing ribs located within a central spine located along the bottom of a panel receiving slot in the insulative housing. Cavities intersect the slots receiving the circuit panels and the terminals can be inserted into the respective cavities from the bottom, with the posts extending upwardly from the base securing the terminals by engagement with the central spine. Panel support guides extend upwardly at either end of the housing and ridges on flexible walls in the housing stabilize the modules in the sockets.

Description

Circuit panel sockets with clover contacts

Since this is an open matter, no full text was included.

1 is a perspective view of a socket provided in a preferred embodiment of the present invention at the end of a circuit panel of a single in-line memory module showing an exploded view of the upper portion of the panel receiving slot;

2 is a diagram showing a deflection (in dashed lines) as determined by analysis of a finite element of a terminal when the terminal used in the socket and the circuit panel are inserted between both beams.

3 is a cross-sectional view taken along line 3-3 of FIG. 1 showing the position of the terminal in the housing and showing the contact surface of a panel support member located at the housing end,

Claims (11)

In a terminal 10 used to ensure electrical contact with the trace 6 on at least one side of the circuit panel 4, it extends upwards from the base 14 between the beam and the member end stamped from the spring metal blank.

Terminal having a. The terminal of claim 1, wherein the portion of the upward extension (12a) above the loop (12d) is inclined inward. The terminal according to claim 2, wherein the downward extension (12d) is spaced apart from the inwardly inclined portion of the upward extension (12a). 4. Terminal according to claim 3, wherein the contact (12e) in the deepest region of the downward extension (12b) is arranged adjacent to the end of each beam. The terminal according to claim 2, wherein the loop portion (12d) is disposed below the downward extension portion. Terminal according to claim 1, characterized in that the terminal (10) has a barb (16) extending upwardly from the base between both beams (12). The terminal as claimed in claim 6, wherein the upper portion of the barb has substantially the same height as the loop portion. Terminal according to claim 7, characterized in that the downwardly extending contact tail (18) extends from the bottom of the base (14). 9. Terminal according to claim 8, characterized in that the contact tail (18) is aligned with the barb (16). The loop 12d is positioned such that most of the deflection of the terminal occurs within the portion of the terminal between the loop portion 12d, the base 14 and the base 14 and the loop portion 12d. Terminal characterized in that. In an electrical connector for use in securing electrical contact to an adjacent end of a trace 6 on at least one side of a circuit panel 4, the connector has a plurality of terminals having both beams 12 with an inwardly inclined arm ( 10), an insulating housing 22 having at least one upward slot 22, a plurality of upwardly open cavities 24 in communication with the slot 22, and inwardly inclined projections into the slot 22 from both sides; The terminal 10 disposed in the cavity 24 having the arms, the contact 12e positioned adjacent to the lower end of each inwardly inclined arm, and the panel support members disposed at both ends of the insulating housing 20. 30, each panel support member 30 comprising opposed grooves 32 inwardly in communication with each slot 22 and extending on the bowl 22, and a panel spaced above the open upper end of the slot. A relief slot 36 comprising a respective groove 32 comprising a clamping means 34 Disposed in the vicinity of the groove 32 to form a bending wall 38 on one side of each groove, the bending wall 38 being coupled as a part of the panel support member 30 to each end of the bending wall, the panel clamping means (34) is located on the flexure wall, so that the circuit panel can be inserted into the slot (22) so that the contacts engage with the trace adjacent the end. ※ Note: The disclosure is based on the initial application.
