Description
Technical field
The utility model relates to battery structure technical fields, refer in particular to a kind of battery short circuit prevention structure.
Background technique
The anti-short circuit manner of existing band protection circuit battery is that one is socketed on anode with similar in cell diameter
Washer, then the anode pole piece point for protecting circuit is welded on the anode of battery, the battery of this structure is during use, electric
The protection crust in pond is easy by pole piece friction cuttings, and then the insulated hull breakage of battery is made to lead to battery short circuit.
It needs to reform the prior art.
Utility model content
The technical problem to be solved by the utility model is to provide it is a kind of it is low in cost, high reliablity, can effectively prevent electricity
Battery crust is galled in pole leads to the structure of short circuit.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of battery short circuit prevention structure, packet
Battery, insulation spacer and protection circuit plate are included, the protection circuit plate is connect by electrode slice with the battery, the felt pad
Piece is set between the battery and electrode slice.
Further, the insulation spacer is rectangle.
Further, the insulation spacer is equipped with bending impression, one end of the insulation spacer along the bending impression to
Side bending.
Further, the insulation spacer is papery insulation spacer or PP insulation spacer.
Further, the width of the insulation spacer is greater than the width of electrode slice.
Further, the thickness of the insulation spacer is greater than 0.5mm.
Further, adhesive layer is equipped between the insulation spacer and the battery.
The utility model has the beneficial effects that: the utility model has the beneficial effects that: provide it is a kind of low in cost,
Electrode slice is isolated with battery using insulation spacer for the simple battery short circuit prevention structure of structure, the structure, effectively prevents battery
In use, electrode slice is because with battery rubber friction, cutting battery rubber leads to electrode slice and battery short circuit, significantly for a long time
Increase the safety of battery.
Detailed description of the invention
The specific structure of the utility model is described in detail with reference to the accompanying drawing:
Fig. 1 is the overall structure diagram of one embodiment of the utility model；
Fig. 2 is the configuration schematic diagram of one embodiment of the utility model；
Fig. 3 is the overall structure diagram of another embodiment of the utility model；
Fig. 4 is the configuration schematic diagram of another embodiment of the utility model；
1- battery；2- protection circuit plate；3- insulation spacer；4- electrode slice；5- anode washer.
Specific embodiment
For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation
Mode simultaneously cooperates attached drawing to be explained in detail.
Embodiment
A kind of battery short circuit prevention structure referring to FIG. 1 to FIG. 4, including cylindrical battery 1, the insulation spacer being rectangle 3
It is connect with the cathode of protection circuit plate 2, the protection circuit plate 2 with the cathode of battery 1, the anode of protection circuit plate 2 passes through electricity
Pole piece 4 is connect with the anode of the battery 1, and the insulation spacer 3 is set between the battery 1 and electrode slice 4, the insulation
Gasket 3 is equipped with bending impression, and one end of the insulation spacer is bent along the bending impression to side, the portion of insulation spacer bending
Part fits in 5 side of positive washer of battery, and further protection, the insulation spacer can be done to the insulated hull of battery corner
3 width is greater than the width of electrode slice 4, and can effectively prevent electrode slice displacement is more than the protection scope of insulation spacer, the insulation
The thickness of gasket is greater than 0.5mm, can increase the durability of insulation spacer, insulation spacer is between electrode slice and battery in order to prevent
It falls off, the adhesive layer such as Double-face gummed paper is equipped between the insulation spacer and the battery, the insulation spacer is anticorrosive, resistance to
High temperature, it is low temperature resistant, for a long time using will not deformation retract papery insulation spacer, surface cleaning is without greasy dirt, and neat smooth, side
Production cost can be effectively reduced in edge impulse- free robustness, and similarly, insulation spacer may be PP insulation spacer.
In the present embodiment, by the way that electrode slice is isolated with battery with insulation spacer, electrode slice and battery insulation skin are prevented
Friction, cutting cause battery insulation skin damaged, to allow the possibility of electrode slice and battery case contact short circuit, considerably increase electricity
The safety in pond.
As can be seen from the above description, structure is simple the utility model has the beneficial effects that: providing a kind of low in cost
Electrode slice is isolated with battery using insulation spacer for battery short circuit prevention structure, the structure, effectively prevents battery in use process
In, electrode slice is because with battery rubber friction, cutting battery rubber leads to electrode slice and battery short circuit, considerably increases battery for a long time
Safety.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
