Abstract

The invention relates to a plug-type connector with a cable, which has at least one line, a contact carrier, which has at least one contact element, which is connected to the at least one line of the cable, and an encapsulation, which is injected around the cable and the contact carrier, wherein a sealing element for sealing the encapsulation off from the outer sheath of the cable is provided.

Claims (32)

1. Plug-type connector comprising:

a cable, which has at least one wire and an outer sheath;

a contact carrier, which has at least one contact element which is connected to the at least one wire of the cable;

an injection-molded encapsulation around a portion of the cable and the contact carrier, wherein materials of the encapsulation and the contact carrier are fused or welded together to define a solid body, and the encapsulation defines an outer surface of the plug-type connector, the plug-type connector lacking a housing over the encapsulation; and

a sealing member abutting the encapsulation at a cable end of the encapsulation opposite from a contact end of the encapsulation with the contact carrier fused or welded thereto, the sealing member forming a fluid-tight seal between the encapsulation at the cable end thereof and the outer sheath of the cable, the sealing member being disposed outside the encapsulation, wherein the sealing member is pressed against the encapsulation and the outer sheath of the cable by means of a cap secured to the encapsulation, and wherein the encapsulation has fastening means at the cable end of the encapsulation formed concomitantly in an injection process for the formation of the encapsulation, said fastening means being adapted to fasten the cap.

2. Plug-type connector according to claim 1 , wherein the plug-type connector is suitable for high-temperature applications or is a high-temperature plug-type connector.

3. Plug-type connector according to claim 1 , in which the cap is secured to the encapsulation by means of a screw connection, plug connection, press fit, locking connection, snap connection or adhesive bond.

4. Plug-type connector according to claim 1 , in which the encapsulation has an outer thread, said thread being formed on a cable side of the encapsulation, and the cap having an inner thread.

5. Plug-type connector according to claim 1 , in which the sealing member is a gasket or a sealing washer made from heat-resistant plastic.

6. Plug-type connector according to claim 1 , further comprising at least one sliding ring being formed from heat-resistant plastic.

7. Plug-type connector according to claim 6 , in which the sealing member or the at least one sliding ring is formed from fluorocarbon plastic, fluorine plastic or a plastic having a high proportion of fluorine.

8. Plug-type connector according to claim 6 , in which the sealing member or the at least one sliding ring is formed from nitrile-butadiene rubber, hydrogenated nitrile rubber (HNBR), ethylene-propylene-diene rubber (EPDM), ethylene-propylene terpolymer rubber, APTK, PTFE, EFTE, MVQ, VMQ, silicone rubber, fluorosilicone rubber, fluorocarbon rubber, fluorosilicone, fluorine rubber, acrylate rubber, perfluororubber, perfluorinated rubber, polychloroprene rubber, chlorine rubber, chlorosulphonyl-polyethylene rubber, polyester-urethane rubber, polyether-urethane rubber, butyl rubber, FEP, PFA, PVDF or from metal, preferably from copper or from a copper alloy or a combination of at least two of these materials.

9. Plug-type connector according to claim 1 , in which the contact carrier, the encapsulation or the cap are formed from heat-resistant plastic.

10. Plug-type connector according to claim 9 , in which the contact carrier, the encapsulation or the cap are formed from fluorocarbon plastic, fluorine plastic or a plastic having a high proportion of fluorine.

11. Plug-type connector according to claim 9 , in which the contact carrier, the encapsulation or the cap are each formed from polytetrafluoroethane (PTFE or Teflon), EFTE, PPS, PEEK, PPE, PSU, PES, PEI, LCP, ECTFE, PCTFE, PAI, PPO or a combination of at least two of these materials.

12. Plug-type connector according to claim 1 , in which at least two of the contact carrier, the encapsulation and the cap are each formed from the same material.

13. Plug-type connector according to claim 1 , in which at least two of the contact carrier, the encapsulation and the cap are formed from different materials.

14. Plug-type connector according to claim 1 , in which the outer sheath of the cable is formed from a heat-resistant plastic, preferably Teflon.

15. Plug-type connector according to claim 1 , in which a number of contact elements which corresponds to a number of conductors of the cable is provided in the contact carrier.

16. Plug-type connector according to claim 1 , in which the plug-type connector is a plug part, and the contact elements are formed in such a way that a contact with a corresponding mating contact element can be formed on their outer surface.

17. Plug-type connector according to claim 1 , in which the plug-type connector is a counter-plug part and the at least one contact element is formed in such a way that a contact on an inner surface of the at least one contact element can be formed with a corresponding mating contact element.

18. Plug-type connector according to claim 1 , in which the at least one contact element is hermaphroditic.

19. Plug-type connector according to claim 1 , in which the plug-type connector comprises a connecting part provided for connecting the plug-type connector to a counter-plug connector.

20. Plug connector part according claim 19 , in which the connecting part, preferably in a sliding ring, is rotatably mounted on the contact carrier.

21. Plug-type connector according to claim 19 , in which a seal for sealing the contact carrier from the connecting part is provided, the seal preferably being an O-ring.

22. Plug-type connector according to claim 1 , wherein the encapsulation forms an outer contour of the plug-type connector, and wherein the encapsulation is provided absent a housing surrounding the totality of the encapsulation.

23. Plug-type connector comprising:

a cable, which has at least one wire and an outer sheath;

a contact carrier, which has at least one contact element which is connected to the at least one wire of the cable;

an encapsulation which is formed around a portion of the cable and the contact carrier; and

a sealing member abutting the encapsulation and forming a fluid-tight seal between the encapsulation and the outer sheath of the cable, the sealing member being disposed outside the encapsulation, wherein the sealing member is pressed against the encapsulation and the outer sheath of the cable by means of a cap secured to the encapsulation, and wherein the encapsulation has fastening means being formed concomitantly in an injection process for the formation of the encapsulation, said fastening means being adapted to fasten the cap, and in which a monitoring device is provided which, in the event of a relative movement between cap and encapsulation, is changed in such a way that the relative movement which has taken place is detectable.

24. Plug-type connector according to claim 23 , in which the monitoring device comprises a protective sticker or a protective seal, which sticker or which seal is torn or destroyed, respectively, in the event of a relative movement between cap and encapsulation.
