Abstract

A modular high-current connector ( 1 ) has a first housing part ( 7 ) and a second housing part ( 8 ) connected thereto. The second housing part ( 8 ) has an open housing wall ( 10 ). The open housing wall ( 10 ) can be added to by an unlimited number of additional housing parts.

First claim

The invention claimed is:

1. 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 ) arranged on top of the second housing part ( 8 );
a pin contact ( 9 ) having a contact region (K′) and a connection region (A′),
wherein the contact region (K′) of the pin contact ( 9 ) protrudes from the first housing part ( 7 ) on a plug-in side thereof and is adapted to form an electrical contact for plugging into a device socket, and
wherein the connection region (A′) of the pin contact ( 9 ) extends through the first housing part ( 7 ) through the second housing part ( 8 ) into the third housing part ( 13 ); and

a first connection contact element ( 5 ) arranged in the second housing part ( 8 ), the first connection contact element ( 5 ) having a connection region (A) for connecting an electrical line and a contact region (K) with a cylindrical through-opening ( 3 ) for receiving the pin contact ( 9 ),
a second connection contact element ( 5 ) arranged in the third housing part ( 13 ), the second connection contact element ( 5 ) having a further connection region (A) for connecting a further electrical line and a further contact region (K) with a further cylindrical through-opening ( 3 ) for receiving the pin contact ( 9 ),
wherein the second housing part ( 8 ) has an open housing wall ( 10 ), and
wherein the third housing part is fixed to the open housing wall ( 10 ), and
wherein the first connection contact element ( 5 ) includes grooves ( 16 ) into which ribs ( 17 ) of the second housing part ( 8 ) engage, whereby the first connection contact element ( 5 ) is prevented from rotating within the second housing part ( 8 ).

2. The modular high-current connector ( 1 ) as in claim 1 ,
wherein the pin contact ( 9 ) comprises an encircling ring ( 15 ) within the contact region (K′) of the pin contact ( 9 ) that protrudes from the first housing part ( 7 ).

3. The modular high-current connector ( 1 ) as in claim 1 ,
wherein the connection region (A) of the first connection contact element ( 5 ) comprises a cylindrical opening ( 2 ) configured as a crimp connection to the electrical line, and
wherein the further connection region (A) of the second connection contact element ( 5 ) comprises a further cylindrical opening ( 2 ) configured as a further crimp connection to the further electrical line.

4. The modular high-current connector ( 1 ) as in claim 1 ,
further comprising a fixing means ( 14 ) for fixing the first connection contact element ( 5 ) in the second housing part ( 8 ).
