Circuit board assembly with built in wire gripper

Claim 2

A circuit board assembly with built-in strain relief, comprising: a housing for a circuit board, the housing including a top cover below which the circuit board may be positioned; a circuit board carrying a plurality of terminals for connecting various points on the circuit board to a corresponding plurality of external wires, said terminals being positioned below the top cover; a plurality of apertures formed in the top cover, each of said apertures being in substantial vertical alignment with a corresponding one of the terminals and being adapted to receive a wire which is to be bonded to the corresponding terminal; a plurality of wire grippers formed in the top cover of the housing, each of said grippers being associated with one of said apertures and each comprising: three fingers integrally formed with the top cover, the fingers extending downwardly from the front cover and spaced apart from each other substantially equally around the perimeter of the associated aperture, the fingers being formed so as to flex outwardly to permit a wire to be inserted through the associated aperture and between the fingers, but holding the inserted wire against removal in the opposite direction and holding the wire in substantial registration with an underlying terminal.

Claim 3

A circuit board assembly as set forth in claim 1 wherein each finger terminates in a wire-gripping edge.

Claim 4

A circuit board assembly as set forth in claim 1 wherein the top cover includes a plurality of spacers which extend downwardly from the top cover for spacing the circuit board a selected distance from the top cover.

Claim 5

A circuit board assembly, comprising: a housing for a circuit board, the housing having a top cover and a base; a circuit board located in the housing between the top cover and the base; a plurality of spacers extending downwardly from the top cover for spacing the circuit board a selected distance from the top cover; a plurality of terminals extending from an edge of the circuit board and located within the housing; a plurality of apertures formed in the top cover, each of said apertures being in substantial vertical alignment with a corresponding one of the terminals and being adapted to receive a wire which is to be bonded to the corresponding terminal; a plurality of wire grippers formed in the top cover of the housing, each of said grippers being associated with one of the apertures and each comprising; three fingers integrally formed with the top cover, extending downwardly therefrom, and spaced apart from each other around the perimeter of the associated aperture, the fingers each terminating in an inwardly protruding, wire-gripping edge and being formed so as to flex outwardly when a wire is inserted into the associated aperture and pushed through the fingers, thereby to hold the inserted wire against removal in the opposite direction and to hold the wire in substantial registration with an underlying terminal.

Claim 6

A circuit board assembly, comprising: a housing for a circuit board, the housing having a top cover and a base; a circuit board located in the housing between the top cover and the base; a plurality of spacers extending downwardly from the top cover for spacing the circuit board a selected distance from the top cover; a plurality of terminals extending from an edge of the circuit board and located within the housing; a plurality of apertures formed in the top cover, each of said apertures being in substantial vertical alignment with a corresponding one of the terminals and being adapted to receive a wire which is to be bonded to the corresponding terminal; a plurality of wire grippers formed in the top cover of the housing, each of said grippers being associated with one of the apertures and each comprising; three fingers integrally formed with the top cover, extending downwardly therefrom, and spaced apart from each other around the perimeter of the associated aperture, the fingers each terminating in an inwardly protruding, wire-gripping edge and being formed so as to flex outwardly when a wire is inserted into the associated aperture and pushed through the fingers, thereby to hold the inserted wire against removal in the opposite direction and to hold the wire in substantial registration with an underlying terminal.
