Abstract

A cooling lance is provided to cool an electrically conductive contact body. The cooling lance includes a lance body, a fluid line extending through the lance body, and a flexible cooling bladder positioned on an end of the lance body and in fluidic communication with the fluid line.

First claim

What is claimed is:

1. A cooling lance for cooling an electrically conductive contact body, comprising:
a lance body;
a fluid line extending through the lance body; and
a flexible cooling bladder positioned on an end of the lance body and in fluidic communication with the fluid line, the flexible cooling bladder is insertable into a cooling bladder receiving chamber of the electrically conductive contact body.

2. The cooling lance according to claim 1 , wherein the lance body is an injection-molded monolithic piece.

3. The cooling lance according to claim 1 , wherein the lance body includes a pair of tubular bodies that are symmetrically arranged in relation to one another.

4. The cooling lance according to claim 3 , wherein the pair of tubular bodies form the fluid line.

5. The cooling lance according to claim 4 , wherein a diameter of the fluid line increases from a diameter D 1 to a diameter D 2 along a longitudinal direction L of the lance body.

6. The cooling lance according to claim 3 , wherein one of the pair of tubular bodies is a fluid inlet and another of the pair of tubular bodies is a fluid outlet.

7. The cooling lance according to claim 6 , wherein the pair of tubular bodies open into the flexible cooling bladder.

8. The cooling lance according to claim 7 , wherein the flexible cooling bladder is coolant-resistant.

9. The cooling lance according to claim 1 , wherein the flexible cooling bladder is coolant-resistant.

10. The cooling lance according to claim 1 , wherein the flexible cooling bladder is rigidly secured to the lance body.

11. The cooling lance according to claim 10 , wherein the flexible cooling bladder is made of a material with dielectric properties.

12. The cooling lance according to claim 10 , wherein the flexible cooling bladder is made from an elastic membrane.

13. The cooling lance according to claim 1 , wherein the flexible cooling bladder has an expansion ratio of 8:1.

14. An electrical connector for connection of electrical conductors, comprising:
an electrically conductive contact body having a cooling bladder receiving chamber;
a cooling lance received by the contact body and having:
a lance body;
a fluid line passing through the lance body; and
a flexible cooling bladder in fluidic communication with the fluid line and positioned in the cooling bladder receiving chamber.

15. The electrical connector according to claim 14 , wherein the contact body includes a lance receiving space extending into the cooling bladder receiving chamber corresponding with the lance body.

16. The electrical connector according to claim 15 , wherein the cooling lance is rigidly secured to the contact body.

17. The electrical connector according to claim 15 , wherein the cooling bladder receiving chamber is occluded by the cooling lance.

18. The electrical connector according to claim 15 , wherein the flexible cooling bladder expands and abuts against a wall of the cooling bladder receiving chamber when filled with a fluid.

19. The electrical connector according to claim 18 , wherein the flexible cooling bladder contracts and is arranged tension-free in the cooling bladder receiving chamber when emptied of the fluid.

20. The electrical connector according to claim 14 , further comprising a battery cell connected to the contact body.

21. The electrical connector according to claim 14 , wherein the lance body includes a pair of tubular bodies that are symmetrically arranged in relation to one another.

22. The electrical connector according to claim 21 , wherein the pair of tubular bodies form the fluid line.

23. The electrical connector according to claim 22 , wherein a diameter of the fluid line increases from a diameter D 1 to a diameter D 2 along a longitudinal direction L of the lance body.

24. The electrical connector according to claim 23 , wherein one of the pair of tubular bodies is a fluid inlet and another of the pair of tubular bodies is a fluid outlet.

25. The electrical connector according to claim 24 , wherein the pair of tubular bodies open into the flexible cooling bladder.

26. The electrical connector according to claim 14 , wherein the flexible cooling bladder is made from an elastic membrane.

27. The electrical connector according to claim 26 , wherein the flexible cooling bladder has an expansion ratio of 8:1.
