Abstract

A modular high-current connector (1) has a first housing part (7) and a second housing part (8) connected thereto. The high-current connector (1) has a pin contact (9), the pin contact (9) being substantially cylindrical and having a connection region (A′) and a contact region (K′) for making electrical contact with a device socket or a mating connector. The contact region (K′) of the pin contact (9) projects out of the high-current connector (1) on the plug-in side.

First claim

The invention claimed is:

1. A modular high-current connector ( 1 ), comprising:
a first housing part ( 7 );
an insulating body ( 19 ) which is arranged in part in the first housing part ( 7 ) and which protrudes from the first housing part ( 7 ) on a plug-in side;
a second housing part ( 8 ) connected to the first housing part ( 7 ); and
a substantially cylindrical pin contact ( 9 ),
wherein the pin contact ( 9 ) has
a connection region (A′) and
a contact region (K′),

wherein the contact region (K′) of the pin contact ( 9 ) protrudes from the high-current connector ( 1 ) on the plug-in side for establishing electrical contact with a device socket or a mating connector.

2. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the contact region (K′) of the pin contact ( 9 ) has
a circumferential ring ( 15 ) and
a circumferential thread ( 18 ), and

wherein the circumferential thread ( 18 ) runs in a plug-in direction (SR) of the pin contact ( 9 ) starting from the circumferential ring ( 15 ).

3. The modular high-current connector ( 1 ) as claimed in claim 2 ,
wherein the insulating body ( 19 ) encloses the pin contact ( 9 ) against the plug-in direction (SR) starting from the circumferential ring ( 15 ).

4. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the connection region (A′) of the pin contact ( 9 ) is at least partially enclosed by the insulating body ( 19 ).

5. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the pin contact ( 9 ) has two circumferential grooves ( 20 , 20 ′), in each of which there is arranged a ring seal ( 21 ) for sealing the pin contact ( 9 ) within the insulating body ( 19 ).

6. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the high-current connector has at least one connection contact element ( 5 ) for establishing an electrical connection to a line to be connected, and
wherein the connection contact element ( 5 ) or the connection contact elements ( 5 ) are each electrically conductively connected to the pin contact ( 9 ).

7. The modular high-current connector ( 1 ) as claimed in claim 6 ,
wherein the connection contact element or the connection contact elements consist of pure copper.

8. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the second housing part ( 8 ) has an open housing wall ( 10 ) which is closable by means of a housing cover ( 12 ) or to which a further housing part is fixable.

9. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the modular high-current connector ( 1 ) has a third housing part ( 13 ).

10. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein all housing parts consist of an aluminum die-cast material.

11. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the insulating body ( 19 ) consists of polyamide.

12. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the pin contact ( 9 ) consists of pure copper.

13. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the first housing part ( 7 ) and the second housing part ( 8 ) connected thereto are embodied in one part.

14. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein at least one housing part has a thermochromic element.

15. The modular high-current connector ( 1 ) as claimed in claim 14 ,
wherein the thermochromic element is designed to visually indicate an overloading of the high-current connector ( 1 ).

16. The modular high-current connector ( 1 ) as claimed in claim 1 ,
wherein the pin contact ( 9 ) has an axial opening in an end face of the contact region (K′), the axial opening being configured to receive an Allen key.

17. A modular high-current connector ( 1 ), comprising:
a first housing part ( 7 );
a second housing part ( 8 ) connected to the first housing part ( 7 );
a third housing part ( 13 ); and
a substantially cylindrical pin contact ( 9 ), wherein the substantially cylindrical pin contact ( 9 ) has
a connection region (A′) and
a contact region (K′),

wherein the contact region (K′) of the substantially cylindrical pin contact ( 9 ) protrudes from the high-current connector ( 1 ) on a plug-in side for establishing electrical contact with a device socket or a mating connector
wherein the modular high-current connector ( 1 ) has further housing parts comprising a fourth housing part, a fifth housing part, and a sixth housing part, and
wherein the further housing parts are embodied similarly to the third housing part ( 13 ).

18. The modular high-current connector ( 1 ) as claimed in claim 17 ,
wherein a connection contact element ( 5 ) is arranged in each case in the second housing part ( 8 ) and/or in the third housing part ( 13 ) and/or in the fourth housing part and/or in the fifth housing part and/or in the sixth housing part.
