Description

A kind of novel elastic polarity sheet and battery case

Technical field

This utility model relates to battery spring structure, particularly relates to a kind of novel elastic polarity sheet and battery case.

Background technology

Electronic installation arranges battery containing room at present, is used for loading set of cells, to provide electronic installation Required electric energy.The electric energy of battery is transferred to electrical equipment by battery spring lamination by battery containing room.

In prior art, the battery spring lamination complex manufacturing on market, as it is shown in figure 1, need first to divide Do not produce spring 10 and conducting strip 20, then spring 10 be welded on the pad in conducting strip 20, Need through multiple production technologies, and need substantial amounts of artificial participation, it is impossible to realize machine automatization makeup Join.And electronic installation is when using this type of battery spring lamination, in transport and assembling, easily produce vibrations, Or after a long time use, solder joint easily comes off, be easily caused loose contact problem, and spring easily from Come off on conducting strip, lose electric action.

Utility model content

In order to solve the shortcoming and defect mentioned in above-mentioned prior art, this utility model provides a kind of novel Elastic polarity sheet, including shell fragment and substrate, described shell fragment is one-body molded with described substrate, described shell fragment The subregion die cut of the most described substrate forms, and spiral is cone-shaped from bottom to top.

Further, described substrate edges is provided with pin, and described pin is one-body molded with described substrate.

Further, described shell fragment end is provided with through hole.

Further, described novel elastic polarity sheet is made up of elastic conduction metal material.

This utility model also provides for a kind of battery case, and described battery case is provided with that as above any one is new Type elasticity polarity sheet.

The novel elastic polarity sheet that this utility model provides, battery clamping is used to be difficult to loosen, conductive effect Good, the problem that there is not loose contact.The novel elastic polarity sheet that this utility model provides, was producing Cheng Zhong, one-shot forming, technique is simple, and stock utilization is high.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will The accompanying drawing used required in embodiment or description of the prior art is briefly described, it should be apparent that, Accompanying drawing in describing below is embodiments more of the present utility model, comes for those of ordinary skill in the art Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with Accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, It is fully described by, it is clear that described embodiment is a part of embodiment of this utility model rather than complete The embodiment in portion.Based on the embodiment in this utility model, those of ordinary skill in the art are not making The every other embodiment obtained under creative work premise, broadly falls into the scope of this utility model protection.

This utility model provides a kind of novel elastic polarity sheet, including shell fragment 1 and substrate 2, described shell fragment 1 One-body molded with described substrate 2, the subregion punching press of the most described substrate 2 of described shell fragment 1 is cut Cutting and form, spiral is cone-shaped from bottom to top.

The novel elastic polarity chip architecture schematic diagram that Fig. 2 provides for this utility model, as shown in Figure 2: new In type elasticity polarity sheet, shell fragment 1 and substrate 2 belong to one time punching molded.During punching press, first carry out stamping-out Technique, is punched out swirls by raw material.Next carries out deep-drawing technique, by swirls part drawing. Owing to shell fragment 1 is tapered, so repeatedly load-unload to be carried out, first major diameter outer shroud is carried out drawing, right Minor diameter internal ring drawing, major diameter outer shroud drawing distance is shorter, and minor diameter outer shroud drawing distance is longer.? During use, shell fragment 1 is compressed by battery, and shell fragment 1 is relatively big with the contact area of electrode, and conductive effect is good.

Use the novel elastic polarity sheet that this utility model provides, owing to shell fragment 1 and substrate 2 are one-body molded, Shell fragment 1 will not come off from substrate 2, and conductive effect is good, increases the service life.And avoid existing Battery spring lamination (as shown in Figure 1) welding manner, it is possible to achieve mechanization is assembled automatically, improve batch Production efficiency, saves manpower and cost.

Preferably, described substrate 2 edge is provided with pin 201, described pin 201 and described substrate 2 one Molding, as shown in Figure 3.Pin 201 is set on a substrate 2, it is achieved produce the mechanization of assembling；Another Aspect, pin 201 is welded in electronic equipment, and novel elastic polarity sheet is difficult to come off from electronic equipment, Electronic equipment can life-time service.

Preferably, described shell fragment 1 end is provided with through hole 101, as shown in Figure 3.The mesh of through hole 101 is set Be that being easy to positive and negative limit with battery makees sufficiently to contact, conductive effect is more preferable.It should be noted that The size of through hole 101 does not limits at this, according to when being embodied as, and can be according to the specification using battery And specifically set.

It is preferred that described novel elastic polarity sheet is made up of elastic conduction metal material.Use elastic conduction Metal material, shell fragment 1 is after clamped battery takes out, and shell fragment 1 restores to the original state, it is simple to reuse.

This utility model also provides for a kind of battery case, described battery case be additionally provided with as above any one Novel elastic polarity sheet 30, as shown in Figure 4.Owing to battery case employs the new of this utility model offer Type elasticity polarity sheet 30, it is to avoid existing battery spring structure is owing to, in transport and installation process, producing Shake or use the solder joint caused to come off for a long time so that loose contact between spring and polarity substrate Problem, and owing to this novel elastic polarity sheet 30 belongs to one-body molded, easily realize assembling processing Automatization, improves the efficiency producing assembling.

Although the most more employs the terms such as such as shell fragment, substrate, pin, but is not precluded from making By the probability of other term.Use these terms to be only used to more easily and describe and explain this practicality Novel essence；Being construed as any additional restriction is all to disagree with this utility model spirit The back of the body.

Finally it should be noted that various embodiments above only in order to the technical solution of the utility model to be described, rather than It is limited；Although this utility model being described in detail with reference to foregoing embodiments, this area Those of ordinary skill it is understood that the technical scheme described in foregoing embodiments still can be entered by it Row amendment, or the most some or all of technical characteristic is carried out equivalent；And these amendment or Replace, do not make the essence of appropriate technical solution depart from the scope of this utility model each embodiment technical scheme.
