Abstract
The utility model provides a cell-phone special battery including apron and the auxiliary polar plate who is connected with the apron seals the apron, and the apron is equipped with electric energy liquid injection hole, is equipped with the recess on the apron, and the recess makes the apron form a film that can play the relief valve effect, and its breakdown pressure accords with international standard, and this film can be integratively pressed into, compares with prior art, the utility model discloses cell-phone special battery seals the apron and can effectively blast proof.
Description
(1) technical field
The utility model relates to a kind of reserve battery blank cover of mobile phone.
(2) background technology
The mobile phone of selling on the market all adopts the multiple membrane type safety valve cover plate of external production, promptly on the alloy aluminum cover plate, perforate a hole, safety valve is to be compounded in metal film bonding on the aperture by high temperature, when short circuit of mobile phone wiring board or mobile phone extended telephone conversation, when battery produces undue heat, this safety valve plays explosion-proof effect, but when answering film owing to high temperature, easily make metal film hardening at high temperature, and the thickness of metal film becomes inhomogeneous, the actual puncture amount overgauge amount of multiple membrane type safety valve cover plate, therefore, the disruptive pressure of the safety valve of mobile phone reserve battery blank cover does not meet international standard at present.
(3) technology contents
The purpose of this utility model provides a kind of mobile phone reserve battery blank cover that can be effectively explosion-proof.
The utility model is achieved in that a kind of mobile phone reserve battery blank cover, comprises cover plate and the auxiliary pole plate that is connected with cover plate, and cover plate is provided with electric energy liquid hand-hole, on the cover board is provided with groove.
The opening of described groove makes progress, and the bottom of groove and the bottom of cover plate are connected as a single entity.
Open Side Down for described groove, and the top of groove and the top of cover plate are connected as a single entity.
The utility model is owing to adopt said structure, on the cover board form a film that can play the safety valve effect, the disruptive pressure of this film meets international standard, and but this film integraty is pressed into, can realize standardized production, compared with prior art, the utility model mobile phone reserve battery blank cover can be effectively explosion-proof.
(4) description of drawings
The cutaway view of the utility model mobile phone reserve battery blank cover shown in Figure 1;
The floor map of the utility model mobile phone reserve battery blank cover shown in Figure 2.
(5) embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to figure 1,2, the utility model mobile phone reserve battery blank cover comprises cover plate 1 and auxiliary pole plate 3, and auxiliary pole plate 3 is connected with insulator 2 by screw 5 with cover plate, and cover plate 1 is provided with electric energy liquid hand-hole 7, electric energy liquid hand-hole 7 is provided with groove 4 by the screw sealing on cover plate 1.The opening of groove 4 upwards, the bottom of the bottom of groove 4 and cover plate 1 is connected as a single entity, groove 4 makes cover plate 1 form the film 6 that can play the safety valve effect, the disruptive pressure of film 6 is 5-8KG, this disruptive pressure meets international standard, the opening of groove 4 also can be downward, and the top of the top of groove 4 and cover plate 1 is connected as a single entity, and film 6 is positioned at the top of cover plate 1.
The utility model mobile phone reserve battery blank cover has been owing to adopted said structure, but this film integraty be pressed into, therefore can realize standardized production.
