Abstract

A sealing structure between terminals and a battery cover, which comprises terminals(11)and a battery cover(12). The terminals(11)are embedded in the battery cover(12). The tail end of the terminals(11)has a projecting part(31)pressing on a battery cover bearing region(21). Furthermore, at least one rubber sealing circle(14)is equipped between the terminals(11)and the battery cover bearing region(21). The utility model separates the procedure of injection molding and that of pressing and sealing terminals, thus avoiding unnecessary waste, and at the same time on this basis adds the sealing of rubber sealing circle which can be placed one or more in different places, thus completely avoiding the problem of not being strictly sealed.

Description

Hermetically-sealed construction between a kind of terminal and the battery cover

Technical field

The utility model relates to the sealing between the sealing of storage battery, particularly terminal and the battery cover.

Background technology

In the structure of lead acid accumulator, as shown in Figure 1, traditional production technology is that terminal 11 is injected in the battery cover 12.Just terminal or middle cover together need be scrapped as middle cover quality problems or terminal quality problems take place when making in the production process, easily be produced bigger waste; Because of traditional handicraft is with plastics and the pressing of metal terminal high pressure or between increases the material of fluid sealant and so on, thereby realize sealing, so still there is poorly sealed possibility in this kind structure.

Summary of the invention

The purpose of this utility model is to avoid the deficiencies in the prior art part and propose hermetically-sealed construction between a kind of terminal and the battery cover, and the injection moulding of this structure separates with the sub-operation of end-blocking, can avoid unnecessary waste; Increase simultaneously the sealing of rubber seal on this basis, sealing ring can be placed one or more at diverse location, thoroughly solves poorly sealed problem.

The utility model is realized by adopting following technical scheme:

Design the hermetically-sealed construction between a kind of terminal and the battery cover, this structure comprises terminal, battery cover, and described terminal is embedded in the battery cover, and especially the relative battery of the tail end of terminal is stamped one section ledge, and this ledge is pressed on the battery cover confined area.

Hermetically-sealed construction between another terminal of the utility model and the battery cover, also comprise terminal, battery cover, described terminal is embedded in the battery cover, the relative battery of the tail end of terminal is stamped one section ledge, this ledge is pressed on the battery cover confined area, especially between terminal ledge and battery cover confined area at least one rubber seal is arranged.

In battery cover confined area and the rectangular joint of terminal ledge, electronics lid confined area has a groove, and the ccontaining area of section of groove is less than the area of section of rubber seal.

Rubber seal is full of groove and is not stayed the gap by the ledge crimp of terminal, thereby realizes good sealing effectiveness.

Further, at the battery cover confined area auxiliary flute can also be arranged, also less than the area of section of auxiliary rubber sealing ring, the auxiliary rubber sealing ring is by pressing for the ccontaining area of section of auxiliary flute, and the sealing property of battery is further strengthened.

Compared with prior art, the utility model injection moulding separates with the sub-operation of pressing end-blocking, can avoid unnecessary waste; Increase simultaneously the sealing of rubber seal on this basis, sealing ring can be placed one or more at diverse location, thoroughly solves poorly sealed problem.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description.

With reference to Fig. 2, Fig. 3 A and Fig. 3 B, design the hermetically-sealed construction between a kind of terminal and the battery cover, comprise terminal 11, battery cover 12, the two is made respectively or is directly injection-moulded in together, and described terminal 11 is embedded in the battery cover 12, especially, the relative battery cover 12 of the tail end of terminal 11 has one section ledge 31, and this ledge 31 is pressed on the battery cover confined area 21.

Second kind of execution mode of the present utility model is shown in Fig. 4 A, Fig. 4 B, described terminal 11 is embedded in the battery cover 12, the relative battery cover 12 of the tail end of terminal 11 has one section ledge 31, this ledge 31 is pressed on the battery cover confined area 21, and at least one rubber seal 14 is especially arranged between terminal ledge 31 and battery cover confined area 21.

In battery cover confined area 21 and terminal ledge 31 rectangular joints, electronics lid confined area 21 has a groove 52, and groove 52 ccontaining areas of section are less than the area of section of rubber seal 14.

Rubber seal 14 is full of groove 52 and is not stayed the gap by ledge 31 crimps of terminal 11, thereby realizes good sealing effectiveness.

As shown in Figure 5, second kind of execution mode of the present utility model can also have auxiliary flute 53 at battery cover confined area 21 when further implementing, and the ccontaining area of section of auxiliary flute 53 is less than the area of section of auxiliary rubber sealing ring 54.Auxiliary rubber sealing ring 54 is by pressing, and the sealing property of battery is further strengthened.

Facts have proved that the utility model injection moulding separates with the sub-operation of pressing end-blocking, can avoid unnecessary waste; Increase simultaneously the sealing of rubber seal on this basis, sealing ring can be placed one or more at diverse location, thoroughly solves poorly sealed problem.
