The contact is supported by a mounting that is translatably mobile inside the body. ## Claims ### Claim 1 A plug including: at least one contact connected to a cable, and a body extending along a longitudinal axis and inside which the contact is received, wherein the contact is carried by a support mobile in translation in the body, in that the contact includes a lug mounted to pivot relative to a remainder of the contact and the support includes a lug mounted to pivot relative to a remainder of the support, the lug of the contact and the lug of the support being adapted to come into contact with each other when the contact is mounted in the support, and the body has at one longitudinal end an area including at least one raised portion projecting toward an interior of the body, said raised portion and the lug of the support being adapted to come into contact with each other in at least one position of the support in the body. ### Claim 2 (depends on 1) The plug according to claim 1, further including means inside the body exerting a return force adapted to move the contact along the axis of the body. ### Claim 3 (depends on 2) The plug according to claim 2, wherein the support includes at least one arm extending along the axis of the body and having an end surface cooperating with guides produced in an interior wall of the body. ### Claim 4 (depends on 2) The plug according to claim 2, wherein said means include a spring having one end connected to the body and another end connected to the support. ### Claim 5 (depends on 1) The plug according to claim 1, further including a gland holding the plug on the cable. ### Claim 6 (depends on 5) The plug according to claim 5, wherein the gland includes on the cable: two retaining members of complementary shape, a member for clamping said two members, and a split seal. ### Claim 7 (depends on 1) An assembly configured to be connected to the plug according to claim 1, the assembly including: a customer equipment including a chassis and a casing adapted to receive an electronic component, said casing being carried by the chassis, defining a housing, and being disposed facing an opening of the chassis, and a socket including a tubular portion, a plate for fixing the socket to the chassis, and a cover adapted to obstruct the tubular portion, wherein the cover includes a peg adapted to extend toward the tubular portion when the cover is in place thereon, the peg being configured to cooperate with the housing of the casing to allow centring of the socket relative to the casing. ### Claim 8 (depends on 7) The assembly according to claim 7, wherein the peg is configured to be received inside the housing of the casing. ### Claim 9 (depends on 7) The assembly according to claim 7, wherein the peg is removably mounted on a remainder of the cover. ### Claim 10 (depends on 7) A method for mounting a socket on a chassis of a customer equipment to form the assembly according to claim 7, the method comprising: disposing the socket against the chassis in such a way that the peg cooperates with the housing of the casing, and the socket thus disposed is fixed to the chassis. ### Claim 11 (depends on 1) An interconnection system including: a plug according to claim 1; and an assembly configured to be connected to the plug, the assembly including: a customer equipment including a chassis and a casing adapted to receive an electronic component, said casing being carried by the chassis, defining a housing, and being disposed facing an opening of the chassis, and a socket including a tubular portion, a plate for fixing the socket to the chassis, and a cover adapted to obstruct the tubular portion, wherein the cover includes a peg adapted to extend toward the tubular portion when the cover is in place thereon, the peg being configured to cooperate with the housing of the casing to allow centring of the socket relative to the casing. ### Claim 12 (depends on 11) The system according to claim 11, wherein: an area of the body of the plug including at least one raised portion projecting toward the interior of the body includes at least one raised portion projecting towards an exterior of the body and the tubular portion of the socket includes a groove into which said raised portion may clip on connecting the plug and the socket. ### Claim 13 (depends on 11) The system according to claim 11, wherein: once a connection has been made the support is inside the body in a position in which the lug of the contact is released. ### Claim 14 (depends on 11) The system according to claim 11, wherein: an area of the body including the raised portion, the lug of the support, the lug of the contact, and a means exerting a return force adapted to move the contact along the axis of the body are configured so that when a traction force is applied to the plug to disconnect it from the assembly, the support moves in the body to a position in which, via the lug of the support, said raised portion holds the lug of the contact in a position allowing its disconnection from the assembly. ### Claim 15 (depends on 11) The system according to claim 11, wherein the body of the plug, respectively the socket, includes at least one rib and the socket, respectively the body of the plug, includes at least one groove, the groove and the rib being configured to provide polarization on connecting the plug to the socket. ### Claim 16 (depends on 15) The system according to claim 15, wherein the groove extends over only a portion of the body of the plug or the socket, the closed end of the groove defining an abutment position on connecting the plug to the socket.
