Abstract

A current detection electrode comprises a fixed rear cover, an insulating spacer, a thrust spring, a guide sleeve and a detection electrode head, and is characterized in that: the guide sleeve is cylindrical, a guide shaft is arranged along the axial direction in the front end of the guide sleeve, the detection electrode head is arranged on the front end of the guide shaft, the fixed rear cover is arranged on the rear end of the guide sleeve, the insulating spacer is arranged in the guide sleeve and on the front end of the fixed rear cover, and the thrust spring is arranged between the insulating spacer and the guide shaft. The current detection electrode has the advantages that: since the current detection electrode is provided with the thrust spring, the guide shaft can be pushed by the thrust spring to move forward, so that the detection electrode head is in tighter contact with a detected storage battery electrode in the process of detection, the detection electrode head does not need to be frequently replaced, the production cost of storage batteries is reduced, and meanwhile, and detection data are more accurate.

Description

The current detecting electrode

Technical field

The utility model relates to accumulator detection technique field, the current detecting electrode that a kind of accumulator of more specifically saying so adopts when carrying out current detecting.

Background technology

At present, the battery current detecting electrode of prior art, in use; The detecting electrode head usually can produce spark; The front end of detecting electrode head will be melted and shorten, and the data that detect first are inaccurate, thereby has influenced the current detecting work of accumulator; Second will frequent change detecting electrode head in order to obtain precise information, increased the manufacturing cost of accumulator simultaneously.

Summary of the invention

For addressing the above problem; The utility model has designed a kind of accumulator and has used the electric current detecting electrode; Described current detecting electrode is made up of fixedly bonnet, insulation spacer, thrust spring, guide pin bushing, guide shaft, detecting electrode head, it is characterized in that guide pin bushing is set to cylindrical shape, on the inner axis direction of the front end of guide pin bushing guide shaft is set; The front end of guide shaft is provided with the detecting electrode head; The rear end of guide pin bushing is provided with fixedly bonnet, and fixedly the set inside insulation spacer of the front end guide pin bushing of bonnet is provided with thrust spring between insulation spacer and the guide shaft.

The beneficial effect of the utility model thrust spring that has been the current detecting electrode design; Guide shaft promotes forward under the promotion of thrust spring; In the testing process, tightr between detecting electrode head and the battery terminal to be detected, need not frequent change detecting electrode head; Not only reduced the production cost of accumulator, the data that detect simultaneously are more accurate.

Description of drawings:

Accompanying drawing is the structural representation of the utility model, in the accompanying drawing:

1. fixedly bonnet, 2. insulation spacer, 3. thrust spring, 4. guide pin bushing, 5. guide shaft, 6. detecting electrode head.

Embodiment:

In conjunction with accompanying drawing the utility model is described in further detail; So that the public grasps the implementation method of the utility model better; The concrete embodiment of the utility model is: described current detecting electrode is made up of fixedly bonnet 1, insulation spacer 2, thrust spring 3, guide pin bushing 4, guide shaft 5, detecting electrode head 6, it is characterized in that guide pin bushing 4 is set to cylindrical shape, on the inner axis direction of the front end of guide pin bushing 4 guide shaft 5 is set; The front end of guide shaft 5 is provided with detecting electrode head 6; The rear end of guide pin bushing 4 is provided with fixedly bonnet 1, and fixedly the set inside insulation spacer 2 of the front end guide pin bushing 4 of bonnet 1 is provided with thrust spring 3 between insulation spacer 2 and the guide shaft 5.

The beneficial effect of the utility model has been current detecting electrode design thrust spring 3; Guide shaft 5 promotes forward under the promotion of thrust spring 3; In the testing process, tightr between detecting electrode head 6 and the battery terminal to be detected, need not frequent change detecting electrode head; Not only reduced the production cost of accumulator, the data that detect simultaneously are more accurate.
