Abstract
The utility model relates to an erect terminal of a valve-controlled closed lead-acid storage battery. The erect terminal comprises a middle cover, an erect terminal extending out of the middle cover, and a soldering terminal fixedly connected with the erect terminal, and is characterized in that a lead sheath for sealing is arranged between the erect terminal and the middle cover, and the contact parts of the lead sheath and the erect terminal are fused into a whole through a welding gun. The erect terminal has the advantage of good sealing effect, and can effectively solve the problem of acid leakage.
Description
Technical field
The utility model relates to a kind of valve control sealed lead-acid battery and directly goes out the formula terminal.
Background technology
Valve control sealed lead-acid battery directly goes out the formula terminal and is widely used in the lead acid accumulator field, because of it more economizes raw material (lead alloy and the glue that seals) than the structure that pole adds terminal, also save the operation of welding pole and terminal, reduced the risk that secondary welding is brought.Its foundation structure is seen Fig. 1, and its basic structure is the rubber ring (2) of putting " O " type in the bottom of middle cover (1), fills as sealing with epoxy resin (5) on the top of the rubber ring of " O " type then, and binding post (4) is fixed in the middle of the epoxy resin.Because filler is different materials with directly going out the formula terminal, their thermal coefficient of expansion difference, along with user's use, regular meeting descends its adhesion, causes infiltration to climb acid.
It is a kind of common form that battery damages that battery terminal is climbed acid, if instantaneously changing is not handled, even can lead to serious accident, as: fire.It is suitable dislike that the user climbs acid to battery, and how avoiding terminal to climb acid is subject matters of the many battery production producers of puzzlement.
The utility model content
The utility model is to overcome the deficiencies in the prior art and a kind of good sealing effect is provided, and a kind of valve control sealed lead-acid battery that can effectively solve the problem of climbing acid directly goes out the formula terminal.
In order to achieve the above object, the utility model is achieved in that it is that a kind of valve control sealed lead-acid battery directly goes out the formula terminal, comprises middle cover, stretch out middle cover directly go out the formula terminal and and directly go out the binding post that the formula terminal is fixedlyed connected; It is characterized in that: directly going out to be provided with the lead cover that seals between formula terminal and the middle cover, plumbous cover is one with the contact position that directly goes out the formula terminal with the welding gun fusion.
Be provided with the convex edge in the described upper end that directly goes out the formula terminal, this convex edge is one with the contact position, upper end of plumbous cover with the welding gun fusion.
Described plumbous cover is pegged graft mutually with the middle cover mating surface and is tightly connected.
The utility model advantage compared with prior art is that good sealing effect can effectively solve the problem of climbing acid.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 2, it is that a kind of valve control sealed lead-acid battery directly goes out the formula terminal, comprises middle cover 1, stretch out middle cover directly go out formula terminal 3 and and directly go out the binding post 4 that the formula terminal is fixedlyed connected; Directly going out the formula terminal processes with lead; Characteristics of the present utility model are: directly going out to be provided with the lead cover 2 that seals between formula terminal 3 and the middle cover 1, plumbous cover is one with the contact position that directly goes out the formula terminal with the welding gun fusion.
In the present embodiment, the upper end that directly goes out formula terminal 3 is provided with convex edge 31, and it is one that the contact position, upper end of this convex edge and plumbous cover 2 is provided with the welding gun fusion, thus better sealing.Plumbous cover 2 is pegged graft mutually with middle cover 1 mating surface and is tightly connected.
When assembling is finished, cooperate plumbous projection 31 that directly goes out formula terminal 3 and lead cover the place, slit lead to be fused together, just blocked the direct channel of climbing acid, promptly block the sour passage that climbs out of along the external diameter of terminal with welding gun.
By technique scheme, directly going out formula terminal 3 and plumbous cover cooperates the place, slit to design plumbous protruding 31, this projection cooperates the slit to play important effect for welded closure, when welding, the heat that welding gun provides almost all accumulates in the position of projection, and making lead that the lead of boss puts and the plumbous projection while scorification that directly goes out the formula terminal is one.The lead of fusion has sealed the cooperation slit of plumbous cover and terminal at once.As everyone knows, plumbous solubility in acid can be ignored, and has cut off with lead sealing and has climbed sour passage, also directly goes out the sour problem of climbing of formula terminal with regard to having solved.So directly going out the plumbous boss at formula terminal and place, plumbous cover cooperation slit is the key of this hermetically-sealed construction.
Claims (3)
1. a valve control sealed lead-acid battery directly goes out the formula terminal, comprises middle cover, stretch out middle cover directly go out the formula terminal and and directly go out the binding post that the formula terminal is fixedlyed connected; It is characterized in that: directly going out to be provided with the lead cover (2) that seals between formula terminal (3) and the middle cover (1), plumbous cover is one with the contact position that directly goes out the formula terminal with the welding gun fusion.
