Abstract

A device for measuring an electrical quantity of a storage battery has a measuring element disposed in a housing. The measuring element is connected in series with a storage battery. The contact elements which are led through the housing are sealed off by way of sealing elements.

Claims

1. A device for measuring an electrical quantity of a storage battery, comprising:

a housing;

a measuring element disposed in said housing and having a first connection and a second connection;

a first contact element electrically connected to said first connection; and

a second contact element electrically connected to said second connection;

said housing having a recess formed therein for allowing at least one of said first and second contact elements to be guided therethrough; and

a sealing element disposed between said housing and said at least one contact element.

2. The device according to claim 1, wherein said sealing element is integrally formed in a single piece with said housing.

3. The device according to claim 2, wherein said sealing element is formed with a bevel facing toward an exterior of said housing.

4. The device according to claim 1, which comprises evaluation electronics disposed in an interior of said housing, and a quantity of potting compound for sealing said evaluation electronics.

5. The device according to claim 1, wherein said first contact element is joined to form a single piece with a pole terminal, and said pole terminal has a recess through which said second contact element is connected to said second connection of said measuring element.

6. The device according to claim 5, which comprises an insulating sleeve disposed between said pole terminal and said second contact element.
