Abstract

A measuring assembly for measuring a temperature of a test body is provided, wherein at least two separate wires suitable for thermal conduction are led away from a test body and combined into a wire bundle at a distance from the test body, and wherein a temperature sensor is attached to the wire bundle by clamping action by means of a holder. Preferably, the holder comprises a holder base having an inner side and an outer side, and spring clips connected thereto, wherein a recess for receiving a temperature sensor is arranged on the inner side of the holder base, and wherein two of the spring clips are arranged opposite each other with respect to the holder base and are adapted to generate a clamping force towards the inner side of the holder base.

First claim

1 . A measuring assembly for measuring a temperature of a test body, wherein
at least two wires which are separated from one another and which are suitable for thermal conduction are led away from a test body and which are combined at a distance from the test body to form a wire bundle, and a temperature sensor being fastened by means of a holder to the wire bundle by a clamping effect.

2 . The measuring assembly according to claim 1 , wherein all wires are fixed to the test body at different points.

3 . The measuring assembly according to claim 1 , wherein the wires are combined in the region of the wire bundle by a bundling means and the temperature sensor is pressed against the bundling means by the holder.

4 . The measuring assembly according to claim 3 , wherein the bundling means is a hot crimp.

5 . The measuring assembly according to claim 1 , wherein the wires serve as supply lines of electric current to the test body.

6 . The measuring assembly according to claim 1 , wherein the test body is an electric motor.

7 . A holder comprising a holder base having an inner side and an outer side and spring clips connected thereto, wherein a recess for receiving a temperature sensor is arranged on the inner side of the holder base, and wherein two of the spring clips are arranged opposite each other with respect to the holder base and are configured to generate a clamping force towards the inner side of the holder base.

8 . The holder according to claim 7 , wherein the recess comprises a stop for inhibiting a movement of a temperature sensor to be inserted into the recess out of the recess.

9 . The holder according to claim 7 , wherein a clamping tab is provided and suitable for fixing a temperature sensor to be inserted in the recess.

10 . The holder according to claim 8 , wherein the recess comprises an opening that allows electrical cables to be guided into the recess.

11 . The holder according to claim 7 , wherein the recess is shaped in such a way that a temperature sensor to be inserted can be inserted in an at least partially form-fitting manner into the recess.

12 . The holder according to claim 7 , wherein two additional spring clips are arranged opposite each other with respect to the holder base and are adapted to generate a clamping force towards the inner side of the holder base.

13 . The holder according to claim 7 , wherein the spring clips are adapted to at least partially embrace an oval-shaped measuring body to produce a clamping effect and thus effect attachment to the measuring body, wherein the spring clips bear against the measuring body substantially in a form-fitting manner but in an undersized manner.

14 . The holder according to claim 7 , wherein the material of the spring clips is spring-elastic at a temperature load of 100° C. to 200° C.
