Electric circuit board assembly

Claim 2

An electric circuit board assembly comprising an electric circuit board and an electrical connector mounted thereto, said board comprising a front edge, a centrally located substantially rectangularly shaped cut-out in said front edge, said cut-out being defined by oppositely facing side edge parts and a substantially straight front edge surface, recess means provided on said board adjacent to each of said side edge parts of said cut-out, and a plurality of face contacts on a first surface of said board extending towards said front edge surface and being electrically connected to said connector; said connector having an elongated body including a front surface, a back surface, a top surface, a bottom surface and opposite side edges, a groove in each of said side edges of said body extending from said front surface to said back surface, electrical contacts in said body in electrical connection with said face contacts, said body having a width substantially equal to the length of said substantially straight front edge surface of said cut-out and said side edge parts of said cut-out being received in said grooves of said connector, such that said back surface of said body is substantially flush with said front edge of said board adjacent to said side edge parts, detent means integral with said body and extending downwardly into said grooves and being received in said recess means to retain said board and said connector together, a slot partially separating said detent means from said body whereby said detent means is resiliently deflectable from said body to permit entry of said detent means into the respective recess means in the action of loading said body to said board in a direction planar to said board to provide a snap-together engagement between said board and said connector.

Claim 3

The assembly of claim 1, wherein said slots partially separating said detent means from said body are generally L-shaped.

Claim 4

The assembly of claim 2, werein said body is a unitary molded plastic body.

Claim 5

The assembly of claim 3, wherein said front surface of said body comprises an upper front surface and a lower front surface, said upper front surface extending over and lying against said first surface of said board, and said lower front surface extending over and lying against a second surface of said board opposite to said first surface, and an inner groove extending between said upper front surface and said lower front surface, said inner groove receiving said front edge surface of said cut-out.

Claim 6

The assembly of claim 4, wherein said detent means comprises a detent having a curved surface facing said board.

Claim 7

The assembly of claim 5, wherein said recess means comprises a rectangular aperture in said board.

Claim 8

An electric circuit board assembly comprising an electric circuit board and an electrical connector mounted thereto, said board comprising a front edge, a centrally located substantially rectangularly shaped cut-out in said front edge, said cut-out being defined by oppositely facing side edge parts and a substantially straight front edge surface, recess means provided on said board adjacent to each said side edge parts of said cut-out, said side edge parts including a slot connecting with said recess means and defining a forward part which is partially separated from said board, and a plurality of face contacts on a first surface of said board extending towards said front edge surface and being electrically connected to said connector; said connector having an elongated body including a front surface, a back surface, a top surface, a bottom surface and opposite sides edges, a groove in each of said side edges of said body extending from said front surface to said back surface, electrical contacts in said body in electrical connection with said face contacts, said body having a width substantially equal to the length of said substantially straight front edge surface of said cut-out and said side edge parts of said cut-out being received in said grooves of said connector, such that said back surface of said body is substantially flush with said front edge of said board adjacent to said side edge parts, detent means integral with said body and extending downwardly into said grooves and being received in said recess means to retain said board and said connector together, said forward part being resiliently deflectable from said board to permit entry of said detent means into the respective recess means in the action of loading said body to said board in a direction planar to said board to provide a snap-together engagement between said board and said connector.

Claim 9

An electric circuit board assembly comprising an electric circuit board and an electrical connector mounted thereto, said board comprising a front edge, a centrally located substantially rectangularly shaped cut-out in said front edge, said cut-out being defined by oppositely facing side edge parts and a substantially straight front edge surface, recess means provided on said board adjacent to each said side edge parts of said cut-out, said side edge parts including a slot connecting with said recess means and defining a forward part which is partially separated from said board, and a plurality of face contacts on a first surface of said board extending towards said front edge surface and being electrically connected to said connector; said connector having an elongated body including a front surface, a back surface, a top surface, a bottom surface and opposite sides edges, a groove in each of said side edges of said body extending from said front surface to said back surface, electrical contacts in said body in electrical connection with said face contacts, said body having a width substantially equal to the length of said substantially straight front edge surface of said cut-out and said side edge parts of said cut-out being received in said grooves of said connector, such that said back surface of said body is substantially flush with said front edge of said board adjacent to said side edge parts, detent means integral with said body and extending downwardly into said grooves and being received in said recess means to retain said board and said connector together, said forward part being resiliently deflectable from said board to permit entry of said detent means into the respective recess means in the action of loading said body to said board in a direction planar to said board to provide a snap-together engagement between said board and said connector.

Claim 10

The assembly of claim 7, wherein said slot is substantially parallel to said front edge of said board.

Claim 11

The assembly of claim 8, wherein said body is a unitary molded plastic body.

Claim 12

The assembly of claim 9, wherein said front surface of said body comprises an upper front surface and a lower front surface, said upper front surface extending over and lying against said first surface of said board, and said lower front surface extending over and lying against a second surface of said board opposite to said first surface, and an inner groove extending between said upper front surface and said lower front surface, said inner groove receiving said front edge surface of said cut-out.

Claim 13

The assembly of claim 10, wherein said detent means comprises a rigid detent having a curved surface facing said board.
