Claim 15

A tight electric connector formed of at least one pair of connector members each comprising a casing wherein is housed a plug of deformable insulating material, substantially incompressible, comprising a conducting stud protruding from the plug free surface, the stud having a conical shape with an increasing diameter towards the inside of the plug and being extended by a cylindrical portion of a diameter lower than the greater diameter of the conical portion, the electrical connection resulting from the mere application of the connection member studs on each other in a position of closeness of said members, by pressing said deformable plugs against each other, wherein the free surface of the deformable plug of each connection member protrudes from its housing above the edge thereof and wherein a recess is arranged about the plug in its housing, close to the edge thereof, in order to leave a space for the flow of said deformable material which results from the pressing of said two members against each other, thereby ensuring the sealing and electrical insulation about each conducting stud.

Claim 16

A tight electric connector formed of at least one pair of connector members each comprising a casing wherein is housed a plug of deformable insulating material, substantially incompressible, comprising a conducting stud protruding from the plug free surface, the stud having a conical shape with an increasing diameter towards the inside of the plug and being extended by a cylindrical portion of a diameter lower than the greater diameter of the conical portion, the electrical connection resulting from the mere application of the connection member studs on each other in a position of closeness of said members, by pressing said deformable plugs against each other, wherein the free surface of the deformable plug of each connection member protrudes from its housing above the edge thereof and wherein a recess is arranged about the plug in its housing, close to the edge thereof, in order to leave a space for the flow of said deformable material which results from the pressing of said two members against each other, thereby ensuring the sealing and electrical insulation about each conducting stud.

Claim 17

A tight electric connector formed of at least one pair of connector members each comprising a casing wherein is housed a plug of deformable insulating material, substantially incompressible, comprising a conducting stud protruding from the plug free surface, the electrical connection resulting from the mere application of the connection member studs on each other in a position of closeness of said members, by pressing said deformable plugs against each other, the contact surface of the stud of one of said connection members is conical and the contact surface of the stud of the other is flat, wherein the free surface of the deformable plug of each connection member protrudes from its housing above the edge thereof and wherein a recess is arranged about the plug in its housing, close to the edge thereof, in order to leave a space for the flow of said deformable material which results from the pressing of said two members against each other, thereby ensuring the sealing and electrical insulation about each conducting stud.

Claim 18

A tight electric connector formed of at least one pair of connector members each comprising a casing wherein is housed a plug of deformable insulating material, substantially incompressible, comprising a conducting stud protruding from the plug free surface, the electrical connection resulting from the mere application of the connection member studs on each other in a position of closeness of said members, by pressing said deformable plugs against each other, the contact surface of the stud of one of said connection members is conical and the contact surface of the stud of the other is flat, wherein the free surface of the deformable plug of each connection member protrudes from its housing above the edge thereof and wherein a recess is arranged about the plug in its housing, close to the edge thereof, in order to leave a space for the flow of said deformable material which results from the pressing of said two members against each other, thereby ensuring the sealing and electrical insulation about each conducting stud.

Claim 19

A tight electric connector according to claim 15 wherein said stud having a conical contact surface is made of a conducting material of a greater hardness than that of which is made the stud having a plane surface.
