Abstract
The invention relates to a retractable terminal structure of a lead-acid storage battery, which comprises a middle cover of the lead-acid storage battery, a terminal, a polarity hood and a rubber hood, wherein the terminal passes through the middle cover and extends outward; a bush is sleeved on the terminal; the bush is bonded with the terminal through a bonding agent; and a rubber sleeve is arranged between the bush and the middle cover. Because the structure is adopted in the invention, when a plate grid grows and acts on the terminal to extend upward, the bush slides upward with the terminal; in the upward moving process of the terminal, the combined part of the rubber hood and the terminal is simultaneously deformed and stretched, the polarity hood can not move upward to be hung in the air, the force acting on the terminal caused by production of the battery plate grid is digested, and the occurrence of leakage of electrolyte is avoided, thereby achieving the purpose of protecting equipment and environment; and in addition, because the rubber sleeve has elasticity and a certain amount of lubricating oil is smeared on the bush, the bush is still in close contact with the rubber sleeve in the upward moving process of the bush, thus gas and acid can not leak.
Description
Technical field
The present invention relates to a kind of retractable terminal structure of lead acid accumulator.
Background technology
At present, for traditional lead acid accumulator, in order to prevent oozing out of electrolyte, between battery terminal and the middle cover secure bond of carrying out a kind of rigidity by adhesives such as epoxy resin.But lead acid accumulator is in use, the grid distortion of can constantly growing up, and grid directly acts on battery terminal in the growth strength of battery aspect vertical.
The growth of grid is for small-sized lead acid accumulator, and shorter because of the length of growth, the growing power quantity not sufficient of grid to be destroying bonding between battery terminal and the middle cover, thereby uses this rigidity bonding to be fit to.But for large-scale lead acid accumulator, particularly thin type lead acid accumulator (high and wide ratio is greater than 2), the growth of grid aspect vertically is just very important.Growth along with service time of battery, the growth of grid aspect vertically is big more, and the strength that acts on the battery terminal is big more, thereby destroys the rigidity bonding between battery terminal and the middle cover, oozing out of electrolyte will inevitably take place in this, cause the corrosion of equipment and the pollution of environment.
Summary of the invention
The growth that the present invention need fundamentally solve grid destroys the bonding between battery terminal and the middle cover and produces the Lou problem of acid.The growth of grid is along with the growth of battery service time is almost inevitable.Thereby need improve combination between terminal and the middle cover.The production of digestion battery grid is avoided oozing out of electrolyte taken place, thereby is reached the purpose of protection equipment and environment the active force that terminal produced.
For achieving the above object, the invention provides a kind of retractable terminal structure.Make the battery terminal structure that certain upwards activity space be arranged, can not influence the sealing between battery terminal and the middle cover simultaneously again.
Technical scheme of the present invention is achieved in that retractable terminal structure of lead-acid storage battery, comprise lead acid accumulator middle cover, terminal, polarity cover and rubber cover, terminal passes middle cover and protruding, be arranged with lining on the terminal, lining and terminal are provided with rubber sleeve by adhesives between lining and the middle cover.
Lining of the present invention can be annular cup-like structure, the upper end is wide type opening, there is a circular cavity lower end, the diameter in cavity is identical with the diameter of terminal, just can pass terminal and seamless, between hub sections above the circular cavity and terminal, pour into adhesive, make lining and terminal secure bond.
Rubber sleeve outer wall of the present invention is provided with annular groove, and the correspondence position of middle cover is provided with the annular protrusion that cooperates with annular groove, and the annular protrusion tabling of the annular groove of rubber sleeve and middle cover covers rubber sleeve in being fixed in.
Be coated with one deck lubricating oil between lining and the rubber sleeve, so that it is sour to keep closely contact air tight leakage between lining and the rubber sleeve.
The present invention is owing to adopt said structure; when grid growth acts on terminal and protrudes upward; lining is along with terminal upwards slides; terminal is in the process that moves up; the part that rubber cover combines with terminal is out of shape stretching simultaneously, can not cause that the polarity cover moves up and unsettled, and the production of digestion battery grid is to active force that terminal produced; avoid oozing out of electrolyte taken place, thereby reach the purpose of protection equipment and environment.Smeared certain lubricating oil on elasticity and the lining because of rubber sleeve has in addition, lining is still very tight between lining and the rubber sleeve in the process that moves up, the Lou acid of can not leaking gas.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Referring to Fig. 1, the present invention includes terminal 1, lining 2, polarity cover 3, rubber cover 4, sealing ring 5, connect mother Luo 6, adhesive 7, rubber sleeve 8, middle cover 9.Terminal 1 passes middle cover 9 and protruding, rubber cover 4 is fixedlyed connected with polarity cover 3, polarity cover 3 is set in the top, terminal part (rubber cover 4 can be connected with terminal 1 contact) of stretching out middle cover 9 with rubber cover 4, polarity cover 3 is fixedlyed connected with terminal 1, and connection mother Luo 6 (being used for fixing contact conductor) passes rubber cover 4 and is threaded with terminal 1; Be arranged with lining 2 on the terminal 1, lining 2 and terminal 1 are provided with rubber sleeve 8 by adhesives between lining 2 and the middle cover 9.
Be coated with one deck lubricating oil between lining 2 and the rubber sleeve 8, so that it is sour to keep closely contact air tight leakage between lining 2 and the rubber sleeve 8.
The terminal 1 that the present invention links to each other with electrode passes from middle cover 9 terminal holes by compressed rubber sleeve 8 by adhesive 7 and lining 2 firm adhesions.Reach can stretch up and down again can sealed cell purpose.Above-mentioned lining 2 and middle cover 9 are the ABS material.Rubber sleeve 8, rubber cover 4 and sealing ring 5 are the rubber material.Polarity cover 3 is the polypropylene material.
In use can the move up distance of 8mm of above-mentioned lining 2 and terminal 1.
Above-mentioned rubber cover 4 can be out of shape the length of stretching 8mm.
But the present invention is arranged on the lead acid accumulator operate as normal.In use, when the grid distortion of constantly growing up, grid directly acts on battery terminal in the growth strength of battery aspect vertical; When grid growth acts on terminal and protrudes upward; lining is along with terminal upwards slides; terminal is in the process that moves up; the part that rubber cover combines with terminal is out of shape stretching simultaneously; can not cause that the polarity cover moves up and unsettled; the production of digestion battery grid is avoided oozing out of electrolyte taken place, thereby is reached the purpose of protection equipment and environment the active force that terminal produced.Lining of the present invention and middle cover can be the ABS material.Rubber sleeve, rubber cover and sealing ring can be the rubber material.The polarity cover can be the polypropylene material.
