## Abstract

An electrical connector for interconnecting a flexible printed circuit with a printed circuit board comprises a plug connector and a socket connector. The plug connector includes a plug housing having an end portion of the flexible printed circuit fastened thereon. The socket connector includes a socket housing which defines a cavity open through a top of the socket housing and dimensioned to receive the plug connector therein. A flexible film which carries a plurality of conductors is wrapped around an elastomer, and the elastomer is disposed in the cavity with the conductors arrayed for mating engagement with respective circuit paths on the flexible printed circuit. The flexible film is fastened to a bridge part of the socket housing adjacent to the cavity.

## Claims

### Claim 1

An electrical connector for interconnecting a flexible printed circuit with a printed circuit board, the electrical connector comprising:
a plug connector including a plug housing having an end portion of the flexible printed circuit fastened thereon; and
a socket connector including a socket housing which defines a cavity open through a top of the socket housing and dimensioned to receive the plug connector therein, a flexible film which carries a plurality of conductors and is wrapped around so as to be in direct contact with a substantial portion of an elastomer, the elastomer being disposed in the cavity with the conductors being arrayed for mating engagement with respective circuit paths on the flexible printed circuit, and the flexible film being fastened to a bridge part of the socket housing adjacent to the cavity.

### Claim 2 (depends on 1)

The electrical connector according to claim 1, wherein a pair of said elastomers are disposed in the cavity on opposite sides thereof.

### Claim 3 (depends on 2)

The electrical connector according to claim 2, wherein the flexible printed circuit of the plug connector has independent circuit paths on respective opposite sides of the plug housing, and the plug housing is receivable in the cavity between the pair of elastomers.
