Abstract:
A flat flexible cable (1) includes an elongated flexible insulating substrate (2). A plurality of signal conductors (3) extend longitudinally along at one side of the substrate. A grounding grid (4) is disposed on the opposite side of the substrate. The grounding grid (4) has a random geometric pattern.
Abstract:
An electrical connector for a PGA package is provided for reduction of the height thereof. An electrical connector for a PGA package includes a base housing and a plurality of terminals mounted to the base housing. A cover having through holes adapted for insertion of the PGA pins is provided on the upper side of the base housing. The terminals have a very low profile to reduce the height of the connector.
Abstract:
An electrical connector for a PGA package is provided including structure to permit inspection of solder joints. An electrical connector for a PGA package includes a base housing and a plurality of terminals mounted to the base housing. A cover having through holes adapted for insertion of the PGA pins is slidably provided on the upper side of the base housing. Holes are provided in the terminals to permit inspection of the solder joints.
Abstract:
Disclosed is an improved receptacle contact 1 having first and second contact springs 2 and 3 defining a plug-insertion space 4 therebetween. In the stamped blank the first contact spring 2 includes a straight piece integrally connected to an elongated stem piece 8 and the second contact spring 3 is the handle portion of a crank-like piece 5 whose rod-like piece 10 is integrally connected to the elongated stem piece 8 extending parallel to the first contact spring 2. The arrangement permits a significant reduction of contact-to-contact intervals and results in reduction of punching and assembling operations.

Abstract:
Disclosed is an improvement in a press-fit pin 1 having an elastically deformable area 6 to be press-fitted in a selected through hole in a printed circuit board, the elastically deformable area 6 comprising two parallel, opposite beams 8 connected by an connecting deformable bridge 9, thereby permitting the outer corners 8a of each beam 8 to engage the inner wall of the plated through hole while permitting the connecting deformable bridge 9 to be deformed. The connecting deformable bridge 9 comprises, in cross-section, an connecting flat section 10 extending perpendicular to the opposite beams 8, and two oblique sections 11 extending outward from the opposite ends of the upper flat 10a of the connecting flat section 10 to be contiguous to the opposite beams 8. The press-fit pin has such an connecting flat section in its pressure-deformable area in place of the "V"-shaped area of a conventional press-fit pin, thus eliminating the necessity of forming acute angles in the die-and-punch.
