Background technology
At present, there is following problem in existing electrokinetic cell cap assembly: one, when electrokinetic cell internal short-circuit, and pole position temperature is very high and under vibrating conditions, positive and negative terminals easily conducts, and causes second short circuit, causes safety problem; Two, when pole is subject to external force, easily rotate, cause positive and negative terminals and battery case to come in contact, thus cause external short circuit, bring safety problem; Three, when battery is subject to external force extruding, cause internal short-circuit of battery, there is no split channel, inside can be caused to form very big current.Four, when pole is subject to external force or under Vibration Condition, insulating trip between coping plate and jump ring or the insulator between pole and coping plate (comprising insulating trip and insulated column) easily breaks, causes the poorly sealed or potsherd broken to fall into battery core inside and easily causes safety problem.
Utility model content
The purpose of this utility model is to overcome above shortcoming, provides a kind of good seal performance, and connect reliable, security performance is good; When battery is subject to external compression, positive and negative terminals can be realized and conduct, form split channel, avoid the inner a kind of battery cap assembly forming super-high-current.
For achieving the above object, concrete scheme of the present utility model is as follows: a kind of battery cap assembly, includes coping plate, is located at the first pole of coping plate both sides and the second pole; First pole insulate with coping plate and is connected, and the second pole and coping plate are electrically connected; The conducting strip that a undercut shape is arranged also is provided with bottom first pole.
Wherein, the first pole and the second pole have included a substrate; The substrate of the first pole and the second pole is equipped with main pillar; Coping plate is provided with two pits corresponding with main pillar, is provided with installing hole in pit; The main pillar of the sheathed correspondence of installing hole;
Battery cap assembly also includes for the first pole and the second pole and the fixing jump ring of coping plate, and each main pillar is also provided with the groove coordinated with jump ring;
Also insulating trip is provided with between jump ring on first pole and coping plate.
Wherein, the substrate of the first pole and the second pole is equipped with the insulation column of at least one.
Wherein, sealing ring is equipped with between each main pillar and coping plate.
Wherein, the moulding being located at each main pillar end face is also included.
Wherein, moulding, coping plate, conducting strip, insulating trip, the space mould filling between insulation column, jump ring and sealing ring has plastics.
The beneficial effects of the utility model are: the utility model good seal performance, and connect reliable, security performance is good; When battery is subject to external compression, positive and negative terminals can be realized and conduct, form split channel, avoid inner formation super-high-current, improve electrokinetic cell security performance; Under vibration environment, the insulating part between coping plate and pole can not cause the safe phenomenons such as poorly sealed because breaking; When pole is subject to external force, can not relatively rotate between pole, moulding, coping plate, prevent pole from rotating and battery container short circuit.When there is internal short-circuit, when pole position temperature is very high, pole is connected reliably with coping plate.

Embodiment
Being described in further detail the utility model below in conjunction with the drawings and specific embodiments, is not that practical range of the present utility model is confined to this.
As shown in Figure 1 to Figure 2, a kind of battery cap assembly of the present embodiment, includes coping plate 1, is located at the first pole 2 and the second pole 3 of coping plate 1 both sides; First pole 2 insulate with coping plate 1 and is connected, and the second pole 3 is electrically connected with coping plate 1; The conducting strip 8 that a undercut shape is arranged also is provided with bottom first pole 2.A kind of battery cap assembly of the present embodiment, the first pole 2 and the second pole 3 have included a substrate; The substrate of the first pole 2 and the second pole 3 is equipped with main pillar; Coping plate 1 is provided with two pits corresponding with main pillar, is provided with installing hole in pit; The main pillar of the sheathed correspondence of installing hole; Battery cap assembly also includes the jump ring 6 fixed with coping plate 1 for the first pole 2 and the second pole 3, each main pillar is also provided with the groove coordinated with jump ring 6; Insulating trip 4 is also provided with between jump ring 6 on first pole 2 and coping plate 1.When battery receives external compression, battery case produces excessive deformation, battery core inside can produce internal short-circuit, conducting strip 8 now on the first pole 2 can produce with the battery case after distortion and contact, thus the first pole 2 and the second pole 3 i.e. positive and negative terminals conducting forms external short circuit electric current, battery core inside is avoided to produce super-high-current; When battery battery core generation internal short-circuit, pole position produces higher temperature, and owing to being that what to adopt is high-temperature insulation material between pole and coping plate 1, and what adopt is fixing anti-rotation connection, and pole and coping plate 1 therefore can not be caused to come in contact; Owing to have employed the injection forming process, the sealing property between coping plate 1 and pole is improved, simultaneously under vibrating conditions and pole is subject to external force time, protection insulating material is not subject to breakage.
The utility model good seal performance, connect reliable, security performance is good; When battery is subject to external compression, positive and negative terminals can be realized and conduct, form split channel, avoid inner formation super-high-current, improve electrokinetic cell security performance; Under vibration environment, the insulating part between coping plate 1 and pole can not cause the safe phenomenons such as poorly sealed because breaking; When pole is subject to external force, can not relatively rotate between pole, moulding 9, coping plate 1, prevent pole from rotating and battery container short circuit.When there is internal short-circuit, when pole position temperature is very high, pole is connected reliably with coping plate 1.
A kind of battery cap assembly of the present embodiment, the substrate of the first pole 2 and the second pole 3 is equipped with the insulation column 5 of at least one, and its substrate for the first pole 2 and the second pole 3 and coping plate 1 insulate and isolate.A kind of battery cap assembly of the present embodiment, is equipped with sealing ring 7 between each main pillar and coping plate 1.A kind of battery cap assembly of the present embodiment, also includes the moulding 9 being located at each main pillar end face.A kind of battery cap assembly of the present embodiment, moulding 9, coping plate 1, conducting strip 8, insulating trip 4, the space mould filling between insulation column 5, jump ring 6 and sealing ring 7 has plastics.
Below be only a preferred embodiment of the present utility model, therefore the equivalence that all structures according to the utility model patent claim, feature and principle are done change or modify, and is included in the protection range of the utility model patent application.
