Abstract
The utility model relates to a protective plate hood for a pole terminal type lithium ion power cell. The cell protective plates are sheathed on the two pole terminals of the pole terminal type lithium ion power cell through the two double-faced conduction holes that have metal discs and are arranged on the cell protective plates respectively, and the cell protective plates are electronically connected with the pole terminals through tight nuts. The protective plate hood is characterized in that two grooves for mounting the tight nuts are formed on the top surface of the hood and concentrically arranged with the two pole terminals respectively, pole terminal through holes are formed at the centers of the grooves, and the hood is sheathed on the protective plates to encase and buckle with the protective plates and is fixed together with the protective plates on the body of the pole terminal type lithium ion power cell through the tight nuts that are mounted into the grooves and screwed onto the pole terminals; and pole terminal caps are covered on the openings of the grooves. The hood is injection molded in one time. The protective plate hood can effectively ensure the use safety of cells, and has simple structure, good mechanical properties and convenient assembly and disassembly.
Description
Technical field
The utility model relates to the lithium-ion-power cell accessory, relates in particular to a kind of pole type lithium-ion-power cell baffle protective cover.
Background technology
Lithium ion battery is owing to have the voltage height, the specific energy height, recycle often, volume is little, advantages such as light weight, at mobile phone, be used widely on the portable electric appts such as Digital Video and laptop computer, especially lithium-ion-power cell is a kind of novel high-energy battery, because of its voltage height, capacity is big, high power, flying power is strong, operating temperature range is wide, advantages such as storage life is long and be widely used in electric automobile, electric bicycle, electric tool, electrical equipment field such as accumulation power supply and other need the occasion of high current charge-discharge, and towards artificial satellite and the development of aerospace applications aspect.Pole type lithium-ion-power cell is a kind of electrokinetic cell of widespread usage; for strengthening the fail safe in its use; on the pole face of battery container, baffle is set; baffle is provided with electronic protection circuit; baffle is sleeved on the pole by the conductive hole of the double-sided belt metal dish of setting on it; and is connected by clamp nut and pole conduction, be used to prevent over-charging of battery, cross put, overcurrent, short circuit be so that the generation of unsafe conditions such as blast, the work of assurance cell safety.Therefore baffle is being undertaken important mission to the safety of pole type lithium-ion-power cell.But at present baffle is still for exposed parts, under the operating position of different occasions, is easy to damage, directly jeopardize the safety in utilization and the battery life of lithium-ion-power cell owing to foreign impacts or improper use cause plate breaking strain or device to come off.
The utility model content
Main purpose of the present utility model is at the problems referred to above, provide a kind of simple in structure, barrier propterty can be good, the pole type lithium-ion-power cell baffle protective cover of easy accessibility.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pole type lithium-ion-power cell baffle protective cover; described battery protecting plate is set on two poles of described pole type lithium-ion-power cell by the conductive hole of two double-sided belt metal dish of setting on it; and be connected with described pole conduction by clamp nut; it is characterized in that this protective cover end face respectively with two poles concentric be provided for crouching adorn the groove of described clamp nut; described groove center has the pole via hole; described protective cover coats the baffle spiral-lock on it by the described pole of described pole via hole suit, and the clamp nut and the baffle of packing groove by crouching into and being screwed into pole are fixed on the cell body of described pole type lithium-ion-power cell jointly.
Described groove flap has the pole cap.
This protective cover is the integrated through injection molding part.
The beneficial effects of the utility model are: owing to set up protective cover on the pole type lithium-ion-power cell of existing installation baffle; baffle is placed in the protective cover fully by Global Macros; therefore; baffle can be because of not coming off owing to reasons such as foreign impacts or improper use cause plate breaking strain or device in the battery use; guarantee to bring into play defencive function; effectively guarantee the safety in utilization of battery; extending battery life; the protective cover structure adopts the integrated through injection molding part; be easy to produce in batches; its good mechanical property; protective is strong; assembly and disassembly is convenient; maintenance cost is low, is particularly useful for GPS; fields such as stand-by power supply.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the package assembly intention that the utility model is applied to pole type lithium-ion-power cell.
Among the figure: 1 protective cover, 2 grooves, 3 pole via holes, 4 pole caps, 5 clamp nuts, 6 baffles, 7 conductive holes, 8 poles, 9 pole type lithium-ion-power cells.
Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in detail.
Embodiment
Fig. 1～Fig. 3 illustrates a kind of pole type lithium-ion-power cell baffle protective cover 1 and the application in pole type lithium-ion-power cell 9 thereof; in the prior art; the conductive hole 7 of 6 two double-sided belt metal dish of above-mentioned battery protecting plate is set on two poles 8 of above-mentioned pole type lithium-ion-power cell; and is connected with above-mentioned pole 8 conductions by clamp nut 5, play over-charging of battery, cross put, overcurrent, short circuit be down to the protective action of exploding etc.The effect of double-sided metal dish is thereby battery protecting plate 6 to be connected with pole 8 conductions with clamp nut 5 conductions be connected.The end face that is characterised in that this protective cover 1 of the present utility model respectively with two poles 8 concentric be provided for crouching load the groove 2 of solid nut; above-mentioned groove 2 centers have pole via hole 3; above-mentioned protective cover 1 coats baffles 6 and spiral-lock on it by pole via hole 3 suit poles 8, and the clamp nut 5 of packing groove 2 by crouching into and being screwed into pole 8 is fixed on the cell body of above-mentioned pole type lithium-ion-power cell 9 jointly with baffle 6.Because protective cover 1 covers fully and is buckled on the baffle 6, and baffle 6 can not come off because of reasons such as foreign impacts or improper use cause plate breaking strain or device, reliably brings into play protective effect.Also be stamped pole cap 4 on 2 mouthfuls of above-mentioned grooves, in the use, pole cap 4 need only be filled in the groove mouth, pole 8 can be hidden protection.Above-mentioned protective cover 1 on the make adopts the integrated through injection molding part, and structure is simple and direct, be easy to produce in batches and satisfactory mechanical property.
