Abstract
The utility model discloses a square polar body of a power battery. The square polar body comprises a polar body fixed in a battery cover plate in a penetrating manner, wherein an insulating sealing structure for separating the polar body from the battery cover plate is arranged between the polar body and the battery cover plate; the appearance of a combined part of the polar body and the battery cover plate is square, so that a square anti-torsion structure is formed. The appearance of the combined part of the polar body of the square polar body disclosed by the utility model and the battery cover plate is square, so that the square polar body is reasonable in structure and high in anti-torsion moment; therefore, the polar body cannot be twisted by virtue of a general outer rotation force, and the anti-torsion performance of the polar body is greatly improved; the insulating sealing structure on the combined part of the polar body and the battery cover plate is stable and reliable in structure; the problems of battery liquid leakage, short circuit and the like which are caused by torsion of the polar body are solved.
Description
Technical field: the utility model relates to the polar body that a kind of electrokinetic cell is used.
Background technology: the polar body of general electrokinetic cell is all to penetrate to be fixed on battery cover board Shang， bearing and to be provided with insulation and sealing structure simultaneously and to separate mutually.Because the shape of polar body and battery cover board junction is normally cylindrical, when polar body and outside line are used screw-nut etc. to be connected like this, polar body is probably reversed by external force, destroyed with the insulation and sealing structure of battery cover board junction, cause the problems such as battery leakage, short circuit and lost efficacy, even may cause safety problem.
Summary of the invention: for the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, the square polar body of electrokinetic cell that anti-twisting property is good.
The utility model comprises and penetrates the polar body being fixed in battery cover board, is provided with insulation and sealing structure and separates mutually between polar body and battery cover board, and the appearance at this polar body and position, battery cover board junction is square, forms square anti-torsion structure.
The appearance at polar body of the present utility model and position, battery cover board junction is square, rational in infrastructure, anti-torsion moment is large, general rotation external force is not enough to reverse polar body, greatly improved the anti-twisting property of polar body, the insulation and sealing structure of polar body and battery cover board junction is reliable and stable, has avoided because problems such as the battery leakage that polar body torsion causes, short circuits.
Below in conjunction with drawings and Examples, further illustrate the utility model.
Accompanying drawing explanation: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the decomposing schematic representation of embodiment.
Fig. 3 is another form figure of Fig. 1.
Fig. 4 is the structural representation of I.S.S polar body.
Fig. 5 is the structural representation of tack screwless polar body.
Embodiment: as depicted in figs. 1 and 2, polar body 1 penetrates and is fixed in battery cover board 2, between polar body 1 and battery cover board 2, be provided with insulation and sealing structure and separate mutually, the appearance at this polar body 1 and battery cover board 2 positions, junction is square, forms square anti-torsion structure.Because the corresponding site of polar body 1 is square, anti-torsion moment is naturally larger, conventionally can not reversed by external force.
In the present embodiment; insulation and sealing structure between polar body 1 and battery cover board 2 comprises the assembled rigid insulation pad 3 of split, soft insulating sealing gasket 4 and lower insulation cushion 5; above rigid insulation pad 3, be also provided with the bayonet lock 6 being connected in polar body 1,7 of outer protective covers cover in the outside of rigid insulation pad 3 and bayonet lock 6.Such structural insulation sealing effectiveness is better, produces assembling and also facilitates.Because the kind of electrokinetic cell is different, it is conductive that small part battery requires between anodal polar body 1 and battery cover board 2 when assembling, adopts metal or semiconductor material to meet on the rigid insulation pad in insulation and sealing structure 3, without changing other structure.
In fact, polar body 1 has various ways, and the top of polar body 1 is as shown in Figure 1 external thread type, or as shown in Figure 3, the external screw thread on polar body 1 top is formed by Stud connection.In addition, according to wiring needs, polar body 1 top can be also I.S.S as shown in Figure 4, or 1 top of polar body is as shown in Figure 5 tack screwless.
Claims (3)
1. the square polar body of electrokinetic cell, comprise and penetrate the polar body being fixed in battery cover board, between polar body and battery cover board, being provided with insulation and sealing structure separates mutually, it is characterized by: the appearance at this polar body (1) and battery cover board (2) position, junction is square, forms square anti-torsion structure.
2. the square polar body of electrokinetic cell according to claim 1; it is characterized by: the insulation and sealing structure between polar body (1) and battery cover board (2) comprises the assembled rigid insulation pad (3) of split, soft insulating sealing gasket (4) and lower insulation cushion (5); in rigid insulation pad (3) top, be also provided with the bayonet lock (6) being connected in polar body (1), outer protective cover (7) covers in the outside of rigid insulation pad (3) and bayonet lock (6).
