Claim 14

The connector assembly of claim 12, wherein each of said latch and said latch recess has a substantially L-shape.

Claim 15

The connector assembly of claim 13, including a shoulder on said latch and an edge in ssai latch recess, said shoulder and said edge cooperating to close said second plates upon demating of said connectors by an outwardly directed axial force whereby said first and second plates of said receptacle assembly are moved axially forward.

Claim 16

The connector assembly of claim 14, including a plurality of recesses on said second plates located between said apertures.

Claim 17

A connector assembly comprising mating plug and receptacle connectors, each connector comprising a housing terminating in a forward end, a contact support body mounted in said housing, contact elements mounted in said contact support body and extending towards said forward end of said connector, a protective plate assembly including a first plate laterally fixed in said housing and a second plate laterally slidable in said housing, each of said first and second plates having apertures which are offset from one another when said second plate is in a blocking position and the connectors are not mated, so as to protect said contact elements, said second plate being laterally movable upon mating of second connectors to a second position to position said apertures of said plates to be aligned with each other so as to permit coupling of said contact elements with respective contact elements of the other connector, said protective plate assembly of one of said connectors being axially movable in its housing, and at least one latch mounted on said second plate of said one of said connectors and at least one latch recess provided in said other of said connectors for receiving said latch, said latch and latch recess cooperating in moving said protective plate assembly of said one of said connectors axially forward upon an axially outward movement of one of said connectors associated with demating of said connector assembly.

Claim 18

A connector assembly comprising mating plug and receptacle connectors, each connector comprising a housing terminating in a forward end, a contact support body mounted in said housing, contact elements mounted in said contact support body and extending towards said forward end of said connector, a protective plate assembly including a first plate laterally fixed in said housing and a second plate laterally slidable in said housing, each of said first and second plates having apertures which are offset from one another when said second plate is in a blocking position and the connectors are not mated, so as to protect said contact elements, said second plate being laterally movable upon mating of second connectors to a second position to position said apertures of said plates to be aligned with each other so as to permit coupling of said contact elements with respective contact elements of the other connector, said protective plate assembly of one of said connectors being axially movable in its housing, and at least one latch mounted on said second plate of said one of said connectors and at least one latch recess provided in said other of said connectors for receiving said latch, said latch and latch recess cooperating in moving said protective plate assembly of said one of said connectors axially forward upon an axially outward movement of one of said connectors associated with demating of said connector assembly.

Claim 19

The connector assembly of claim 16, wherein each of said latch and said latch recess has a substantially L-shape.

Claim 20

The connector assembly of claim 17, including a shoulder on said latch and an edge in said latch recess, said shoulder and edge cooperating in axially moving said protective plate assembly.
