The anti-twisting force of the terminal structure is increased by about 50% in comparison with that of a conventional terminal, the twisting resistance of the terminal structure is even superior to that of a matched screw, and the usage requirements of the battery are completely met.
Description
Technical field
The utility model belongs to lead acid accumulator field, particularly the terminal structure of analysing valve control type lead-acid accumulator battery.
Background technology
Controlled lead acid accumulator terminal is generally copper post and lead terminal is combined into, and copper post is responsible for and external electrical equipment connection, and lead terminal is responsible for being connected with inside battery pole plate group.Because bearing various external impacts in terminal position, as the torsion of lock screw generation, urgent power, the tractive effort of connecting line etc. of splicing ear may affect the combination interface of copper post and lead terminal, and then affect conductivity and the sealing effectiveness of terminal, cause battery failure.
With reference to accompanying drawing 1 and accompanying drawing 2, traditional analysing valve control type lead-acid accumulator battery, copper post is generally embedded in and in lead terminal, is wrapped up by lead terminal completely or only expose wiring face, and the gap of terminal and middle cover terminal hole adopts epoxide-resin glue sealing.The shortcoming of this structure is: in the time that external impacts is born at terminal position, this external force transfers to the composition surface for copper post and lead terminal by copper post contact-making surface, causes this composition surface torsional deformation to cause that conduction is bad, and when serious, copper post causes battery failure with plumbous the disengaging.Softer because of lead terminal quality, when stressed, its surface may be out of shape, and lead terminal surface is destroyed because of distortion with the potted line of epoxide-resin glue, causes terminal to climb acid and even leaks acid, the electric equipment of corrosion client.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of terminal structure that improves the torsibility performance of terminal and the analysing valve control type lead-acid accumulator battery of impact resistance is provided.
The utility model is achieved by the following technical programs:
The terminal structure of analysing valve control type lead-acid accumulator battery, comprise lead terminal and copper post, described lead terminal is provided with the cavity of an opening upwards, it is planar that the end face of the head end of described copper post is level, the tail end of described copper post is cone-shaped, described copper post comprises setting up and down and integrated stem and auxiliary section, described stem comprises the cylinder and the multiedge cylinder that set gradually up and down, described cylindrical height is 2～6mm, the inscribed circle of the end face that described cylindrical bottom surface is described multiedge cylinder, the height of described auxiliary section be described copper post height 1/3～3/4, it is interior and mutually adaptive that described auxiliary section is embedded in described cavity.
Preferably, described multiedge cylinder is hexagonal prism.
As another technical scheme, described multiedge cylinder is that cylinder longitudinally cuts through 4 longitudinal sections the rectangle and the spaced cylinder of arc surface that form, and the width of described each rectangle equates with the chord length of described arc surface.
Further, described copper post is built-in with the tapped blind hole of an opening upwards.
Copper post of the present utility model is not wrapped up by lead terminal completely, and the stem that there is no wrapped position is polygon facet, and this polygon facet is wrapped by terminal rubber in the time of concrete use.In the time that copper post is subject to torsion or pulling force, this active force overwhelming majority is born by the composition surface of copper post and terminal rubber, only have small part to put on the composition surface of copper post and lead terminal, and terminal rubber is generally epoxy resin or other unsaturated-resin, its intensity is quite high, therefore can bear larger active force, thereby twisting resistance of the present utility model promotes 50% left and right than traditional terminal, its twisting resistance performance, even higher than supporting screw, can meet the instructions for use of battery completely.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
With reference to accompanying drawing 3 and Fig. 4 and Fig. 5, the terminal structure of analysing valve control type lead-acid accumulator battery, comprise lead terminal 1 and copper post 2, lead terminal 1 comprises shaft 11 and sole 12, lead terminal 1 is provided with the cavity of an opening upwards, copper post 2 is built-in with the tapped blind hole 20 of an opening upwards, it is planar that the end face of the head end 21 of copper post is level, the tail end 22 of copper post 2 is cone-shaped, copper post 2 comprises setting up and down and integrated stem 23 and auxiliary section 24, stem 23 comprises the cylinder 231 and the multiedge cylinder 232 that set gradually up and down, multiedge cylinder 232 is hexagonal prism, the height of cylinder 231 is 2～6mm, cylindrical bottom surface is the inscribed circle of the end face of described multiedge cylinder, the height of described auxiliary section be described copper post height 1/3～3/4, it is interior and mutually adaptive that described auxiliary section is embedded in described cavity.
With reference to accompanying drawing 6, this multiedge cylinder 232 can be also following structure in addition: cylinder is through 4 longitudinal sections rectangle and the spaced cylinder of arc surface that longitudinally cutting forms, and wherein, the width of each rectangle equates with the chord length of arc surface.
In the time producing this terminal structure, the auxiliary section of copper post is placed in the mould of lead terminal, then fills with the plumbous liquid of molten state, after cooled and solidified, copper post forms terminal with plumbous combination.
With reference to accompanying drawing 7, in the time using the terminal structure of this analysing valve control type lead-acid accumulator battery, through after the terminal base of middle cover 3, first adopt sealing ring 4 to seal this terminal structure, then adopt terminal rubber 5 sealings, auxiliary section is wrapped by terminal rubber like this.In the time that copper post is subject to torsion or pulling force, this active force overwhelming majority is born by the composition surface of copper post and terminal rubber, only have small part to put on the composition surface of copper post and lead terminal, because terminal rubber is generally epoxy resin or other unsaturated-resin, its intensity is quite high, therefore can bear larger active force, thereby twisting resistance of the present utility model can effectively be promoted.
Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection range of the present utility model.
