Abstract

A connector assembly includes a battery pole terminal, a measurement element for a battery sensor, and a ground wire in the battery. The measurement element has two connections for connecting to the battery pole terminal and/or the battery cable, such that an electrically-conductive connection exists between the ground wire and the battery pole terminal by means of the measurement element. At least one of the connections is connected to the battery cable or the battery pole terminal by way of a force-locking or interference connection.

Claims

1. A connector assembly, comprising:

a battery pole terminal;

a battery cable for a battery connection;

a measurement element for a battery sensor, said measurement element having a first connection for connecting to said battery pole terminal and a second connection for connecting to said battery cable, forming an electrically conductive connection between said battery cable and said battery pole terminal via said measurement element;

wherein at least one of said first connection and said second connection is a force-locking connection.

2. The connector assembly according to claim 1, wherein said measuring element is disposed directly adjoining said battery pole terminal.

3. The connector assembly according to claim 1, wherein said battery cable has sections and said measuring element is disposed between two sections of said battery cable.

4. The connector assembly according to claim 1, wherein said force-locking connection is effected by compression between a bore formed in said measuring element and a pin-shaped projection on said battery pole terminal, and wherein said bore is undersized relative to said projection.

5. The connector assembly according to claim 1, wherein said force-locking connection is effected by compression between a bore formed in said measuring element and a connecting bolt for said battery cable, and wherein said bore is undersized relative to said projection.

6. The connector assembly according to claim 1, wherein said force-locking connection is effected by compression between a first bore formed in said measuring element and a pin-shaped projection on said battery pole terminal, and by compression between a second bore formed in said measuring element and a connecting bolt for said battery cable, and wherein said first and second bores are undersized relative to the respective said projections.

7. The connector assembly according to claim 1, wherein said battery pole terminal is formed with a through-opening and said battery cable has a connecting bolt protruding through said through-opening, and said connecting bolt is provided with an insulating sleeve in a region with said connecting bolt passes through said through-opening in said battery pole terminal.

8. The connector assembly according to claim 7, wherein said connecting bolt is formed with a pin-shaped projection at an end facing away from said battery cable, and said pin-shaped projection is compressed with said measurement element.

9. The connector assembly according to claim 1, wherein said measurement element is a measurement resistor.

10. The connector assembly according to claim 1, wherein said measurement element is a precision resistor.

11. The connector assembly according to claim 1, wherein said battery pole terminal is compressed onto said measurement element.
