Description

A kind of battery case

Technical field

The utility model relates generally to technical field of electronic components, more particularly to a kind of battery case.

Background technology

In the prior art, existing market upper bracket connection sheet uses point and plane contact with battery case positive and negative electrode connection sheet, If Fig. 1 displayings are a kind of common battery case in the prior art, it includes box body, and battery cavities are formed on box body, Positive strap and negative straps is arranged side by side in the top chamber wall of battery cavities, in the bottom chamber wall of battery cavities also side by side Provided with one group of positive strap and negative straps, after battery is put into battery cavities, the head and bottom of battery respectively with Positive strap and negative straps contact（The contact of point face）, to realize the conducting of circuit.But this structure makes electricity The contact effect in pond is unstable, and it is unreliable with plane contact that watchcase does vibratory test midpoint, will produce separation, ammeter is caused to work Failure.

Utility model content

In view of the deficienciess of the prior art, the utility model is intended to provide a kind of battery case that contact is reliable and stable.

To achieve the above object, the utility model provides the following technical solution：

A kind of battery case includes box body, and battery cavities are formed in the box body, and battery can be mounted on the battery cavities In, prolonged by the fixed holder of holder connection sheet, the top and tail portion of the holder connection sheet on the side wall of the box body It is stretched outside in the battery cavities, the fixed positive strap in the top chamber wall of the battery cavities, the top of the holder connection sheet Portion is connected by holder shrapnel with the positive strap, the fixed negative straps on the bottom surface of the box body, described Be supported with spring on negative straps, the spring be clamped in the negative straps and the holder connection sheet bottom it Between, fixed wiring board on the bracket.

As the preferred of the utility model, there are two columnar holder plugs in the bottom of the holder, described Horizontal step surface is formed on holder plug, the step surface on two holder plugs is located on sustained height, the wiring board It is supported on the step surface.

As the improvement of the utility model, the positive strap bottom is guillotine type connection sheet, the holder bullet Piece includes two reeds, and the bottom of described two reeds is fixed in holder connection sheet, is formed between described two reeds Gap, the guillotine type connection sheet can be caught in the gap, and the width of the guillotine type connection sheet is greater than the gap Width.

Described two reeds are symmetrical arranged as a further improvement of the utility model, and folding is formed on the reed The bending part of turn of bilge, two reeds is mutually drawn close, and the width in the gap is equal to the spacing between two bending parts.

As the specific technical solution of the utility model, the holder connection sheet is made of alloyed copper.

As the preferred of the utility model, the holder connection sheet bottom is pillar, and the pillar is resisted against described Spring.

Compared with prior art, the utility model has the advantage of：Holder connection sheet is used with battery case positive strap Guillotine type contacts, and contact is reliable and stable, and watchcase remains contact during doing experiment, even if can be protected if being subjected to displacement phenomenon It is reliable to hold contact；At two switch jaw contacts, devise bending part, convenient for reduce positive and negative electrode connection sheet be inserted into when insertion force (by Center error between reed and blade of knife switch)；Embedded mode is used when design, so that holder connection sheet is increased pre- Pressure, such holder connection sheet contact between positive and negative electrode connection sheet are closer；Bottom devises the plug for preventing displacement, Reed can be effectively prevented and generate displacement deformation phenomenon；Holder connection sheet is using the preferable alloyed copper of elasticity.

Fig. 3 is the side view of Fig. 2；

Fig. 4 is the close-up schematic view of holder connection sheet in Fig. 2.

Specific implementation mode

The embodiment of battery case in the utility model is described further with reference to attached drawing.

As shown in the picture, the present embodiment is a kind of battery case, includes box body 1, battery cavities have been recessed in box body, Battery can be mounted on battery cavities in, then set one piece of battery cover board in the side wall upper cover of box body, so that it may with by Cell closure in electricity In cell cavity, pass through the 2 fixed holder 3 of holder connection sheet made of alloyed copper, the top of holder connection sheet on the side wall of box body Portion and tail portion extend in battery cavities, the fixed positive strap 4 in the top chamber wall of the battery cavities, with the prior art Unlike, in the present embodiment, positive strap bottom is guillotine type connection sheet 41, and entire positive strap can be around The junction of it and battery cavities cavity wall rotates, and the top of holder connection sheet is connected by holder shrapnel 5 with positive strap 4, is had Body, holder shrapnel includes two reeds 51, and reed is rendered as slanting zigzag, and the bottom of two reeds is separately fixed at The both ends of holder connection sheet top surface, two reeds are symmetrical set, and bending part 511, two springs are formd in the middle part of two reeds Spacing between piece is nearest in bending part position, forms gap between two reed bending parts, the width in the gap is less than The width of guillotine type connection sheet, but since reed is flexible, therefore can exert oneself to squeeze into guillotine type connection sheet in gap, The width support in gap is big, and then under the action of spring-return power, two reeds are close to guillotine type connection sheet, thus will Guillotine type connection sheet securely fixes.Compared with the way of contact of face formula, the connection type of guillotine type due to elastic force effect, The reliability of contact can dramatically be improved（It is less likely to occur to loosen）.

The fixed negative straps 6 on the bottom surface of box body, are supported with spring 8 on the negative straps, and holder connects Contact pin bottom is pillar, and the pillar is resisted against on spring, and spring is clamped in negative straps and holder connection sheet Between bottom, in this way, spring due to being in the state of being pressed, can provide reversed restoring force, this is also improved to holder connection sheet The reliability of contact.There are two columnar holder plugs 31 in the bottom of holder, level is formed on holder plug Step surface 32, the step surface on two holder plugs is located on sustained height, and wiring board 7 is carry on two step surfaces.

The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model Range.
