Abstract
The utility model provides a short-circuit protection structure for a button cell, which is used on the button cell, wherein the structure includes a protection ring arranged on the side surface of the button cell in a sleeving manner; the protection ring is a rubber ring; and a groove for enabling the protection ring to be sleeved on the side surface of the button cell is arranged on the inner ring of the protection ring. Compared with the prior art, the utility model provides the short-circuit protection structure for the button cell, which can be used for preventing the anode and the cathode of the button cell from being contacted with other metal to cause short circuit before the use.
Description
Technical field
The utility model relates to a kind of protection structure, relates in particular to a kind ofly to be applicable to button cell in case the protection structure of battery short circuit.
Background technology
The both positive and negative polarity of button cell is exposed outside, and the spacing between its both positive and negative polarity is very little, and spacing is less than 2 millimeters, and in transportation or installation process, the both positive and negative polarity of button cell is easy to the short circuit because touching other metals.
Summary of the invention
In view of the above problems, the utility model provides a kind of and has been applicable to button cell in case the anti-short-circuit protection structure of the button cell of battery short circuit.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of button cell is prevented short-circuit protection structure, and it is applicable on the button cell, and wherein, this structure comprises the guard circle that is sheathed on this button cell side.
Better, the utility model provides a kind of button cell to prevent short-circuit protection structure, and wherein, described guard circle is rubber ring, and ring is provided with to be sheathed on the groove of this button cell side in the described guard circle, is the through hole of hollow in the described guard circle.
Compared to prior art, the utility model provides a kind of button cell to prevent short-circuit protection structure, prevents from using front button cell both positive and negative polarity to touch other metals and short circuit.
