It also includes a member for blocking the passages of the grid, which is fixed on said grid and is designed for being pierced selectively for the insertion of contacts into a predetermined group of sockets. The invention also relates to a piercing tool, which is designed for being used with one such connector part, and to a corresponding wiring method. ## Claims ### Claim 1 An electrical connector part designed for being coupled with a matching connector part by a front face, said connector part comprising an insulating housing provided with a plurality of sockets for receiving a contact, which have a rear contact insertion end, a sealing joint, which is provided with a plurality of cable passages corresponding to the sockets and which is placed in said housing behind the sockets, and a grid for guiding the cables, which is fixed in the housing behind the sealing joint, wherein said grid supports the joint, said grid being provided with a plurality of cable passages corresponding to the sockets, wherein the connector part comprises a blocking member of the passages of the grid, which is fixed on said grid, and is designed to be pierced selectively for inserting the contacts into a group of predetermined sockets, wherein said blocking member is adapted for preventing the insertion of a contact into a given passage in the absence of a prior piercing of the blocking member into said given passage by a tool. ### Claim 2 (depends on 1) The electrical connector part according to claim 1, further characterized in that said blocking member is a plastic film covering at least partially one face of the grid. ### Claim 3 (depends on 2) The electrical connector part according to claim 2, further characterized in that the film is fastened adhesively or bonded on the grid. ### Claim 4 (depends on 1) The electrical connector part according to claim 1, further characterized in that said blocking member comprises a plate that is fixed on the grid. ### Claim 5 (depends on 1) The electrical connector part according to claim 1, further characterized in that said blocking member is fixed on a rear face of the grid. ### Claim 6 (depends on 5) The electrical connector part according to claim 5, further characterized in that said blocking member has, on the rear face, markings for identifying the sockets. ### Claim 7 An assembly comprising a connector part and a tool for piercing a blocking member of the connector part, wherein the connector part is designed for being coupled with a matching connector part by a front face, said connector part comprising: an insulating housing provided with a plurality of sockets for receiving a contact, which have a rear contact insertion end, a sealing joint, which is provided with a plurality of cable passages corresponding to the sockets and which is placed in said housing behind the sockets, and a grid for guiding the cables, which is fixed in the housing behind the sealing joint, wherein said grid supports the joint, said grid being provided with a plurality of cable passages corresponding to the sockets, wherein the connector part comprises a blocking member of the passages of the grid, which is fixed on said grid, and is designed to be pierced selectively for inserting the contacts into a group of predetermined sockets, said tool comprising a body and a plurality of pins, which project from said body in a parallel manner and in a same direction and which are designed to pierce the blocking member at points corresponding to a predetermined group of the sockets. ### Claim 8 (depends on 7) The assembly according to claim 7, further characterized in that the pins are tapered at free ends of the pins. ### Claim 9 (depends on 7) The assembly according to claim 7, further characterized in that the body is designed to be engaged at least partially in a form-fitting manner from the rear in an interior of the housing. ### Claim 10 (depends on 1, 7) A method of wiring an electrical connector part according to claim 1, in which the following steps are carried out in succession: piercing the blocking member by means of a tool in accordance with claim 7, and introducing into each socket, the access of which has been freed by the piercing operation, a wired contact designed for this purpose.
