Electrical connection device provided with at least one tubular end contact
View Patent ↗An electrical connection device including a socket having at least one axial pressure contact arranged in insulation and at least one annular groove. A plug has at least one tubular contact that is coaxial about a direction of coupling of the plug with the socket. The at least one tubular contact includes a leading end having an end surface. The at least one tubular contact is structured and arranged to co-operate with the at least one axial pressure contact of the socket. The at least one annular groove opens out axially and is structured and arranged to receive therein the at least one tubular contact. At least a portion of the end face of the leading end of the at least one tubular contact presses against the at least one axial pressure contact when the at least one tubular contact is positioned in the at least one annular groove and when the plug is coupled with the socket.

wherein at least a portion of the end surface of the leading end of the at least one tubular contact presses against the at least one axial pressure contact when the at least one tubular contact is positioned in the at least one annular groove and when the plug is coupled with the socket.
2. The electrical connection device of claim 1 , further comprising a pilot contact arranged in an inside space of at least one tubular contact of the plug.
3. The electrical connection device of claim 1 , further comprising a pilot contact arranged in an inside space of at least one of the plug and the socket.
4. The electrical connection device of claim 1 , wherein the electrical connection device comprises a single-pole connection device.
5. The electrical connection device of claim 1 , wherein the at least one tubular contact comprises a single tubular contact.
6. The electrical connection device of claim 1 , wherein the at least one axial pressure contact comprises a single axial pressure contact.
7. The electrical connection device of claim 1 , wherein the plug is adapted to be connected to a cable.
8. The electrical connection device of claim 1 , wherein the socket is adapted to be connected to a cable.
9. The electrical connection device of claim 1 , wherein a thickness and a diameter of said tubular contact respectively corresponds to a thickness and a diameter of said annular groove.
10. An electrical connection system comprising:
a socket comprising an axial pressure contact, insulation, and an annular groove defined by spaced apart inner and outer portions of the insulation;
a plug comprising a coaxially arranged tubular contact having an open leading end; and
the annular groove being structured and arranged to receive therein the coaxially arranged tubular contact,
wherein at least a portion of the leading end of the coaxially arranged tubular contact presses axially against the axial pressure contact when the coaxially arranged tubular contact is positioned in the annular groove and when the plug is coupled with the socket.
11. The electrical connection system of claim 10 , further comprising a pilot contact arranged in an inside space of the plug.
12. The electrical connection system of claim 10 , further comprising a pilot contact arranged in an inside space of the socket.
13. The electrical connection system of claim 10 , wherein the electrical connection system is a single-pole connection device.
14. The electrical connection system of claim 10 , wherein the coaxially arranged tubular contact comprises a single coaxially arranged tubular contact.
15. The electrical connection system of claim 10 , wherein the axial pressure contact comprises a single axial pressure contact.
16. The electrical connection system of claim 10 , wherein the plug is adapted to be connected to a cable.
17. The electrical connection system of claim 10 , wherein the socket is adapted to be connected to a cable.
18. The electrical connection system of claim 10 , wherein a thickness and a diameter of said tubular contact respectively corresponds to a thickness and a diameter of said annular groove.
19. An electrical connection system comprising:
a socket comprising insulation, an annular groove, and an axial pressure contact comprising an annular surface;
the annular groove being defined by spaced apart inner and outer portions of the insulation and being arranged between a front end of the insulation and the annular surface;
a plug comprising a tubular contact having an open leading end; and
the annular groove being structured and arranged to receive therein the tubular contact,
wherein at least a portion of the leading end of the tubular contact presses axially against the annular surface of the axial pressure contact when the tubular contact is positioned in the annular groove.
20. The electrical connection system of claim 19 , wherein the leading end of the tubular contact presses against the annular surface of the axial pressure contact when the plug is coupled with the socket.
21. The electrical connection system of claim 19 , further comprising at least one of:
the plug further comprises a tubular case arranged to surround the tubular contact and a coaxially arranged pilot contact arranged within the tubular contact; and
the socket further comprises a tubular case arranged to surround a front portion of the insulation and a contact arranged within a passage structured and arranged to receive therein a coaxially arranged pilot contact of the plug.
