Description
Technical field
The utility model is related to battery technology field, and in particular to a kind of battery of electric vehicle is with new copper tip and contains
The middle cover of battery of the terminal.
Background technology
Chinese electric car is born for 1985, and 2003 start fast development, by the speed-raising of 5 years, industry size and production and marketing
Amount is per the growth of average annual holding more than 50%, and between particularly 2005,2 years 2006, the development of electric car industry enters well
Spray period.
Lead-acid battery is that positive and negative pole plate interfolded is arranged in battery case, is entered between positive and negative pole plate with insulating barrier
Row isolation.When electrolyte is filled with battery case, electrolyte is chemically reacted with the lead plaster on positive and negative pole plate, when battery charging
When, positive plate lead plaster changes into brown lead oxide, and the sulfuric acid components that the lead plaster on negative plate is changed into spongy lead, lead plaster are discharged into electricity
Solve in liquid, the sulfuric acid concentration in electrolyte is continuously increased, cell voltage rises, put aside energy；When the cell is discharged, positive plate activity
Material changes into lead sulfate, and negative plate active material is also translated into the sulphur in the sulfuric acid in lead sulfate, and Electolyte-absorptive, electrolyte
Acid concentration is constantly reduced, and cell voltage declines, and battery externally exports energy.Therefore the cycle charge-discharge of battery is electric energy and chemical energy
The process constantly changed, finally realizes the storage and release of energy.
Battery is the energy of electric bicycle, is to influence the critical component of electric bicycle performance, is also that restriction is electronic
The key of bicycle development.The need for adapting to electric bicycle, electric bicycle battery have developed rapidly, currently on the market
Electric bicycle more than 95% all use valve-regulated lead-acid battery.According to battery return goods analyze, 6-DZM-20 batteries often because
Copper tip screw stripped thread phenomenon and return goods, found by dissection and analysis, its main cause is that the depth of thread is not enough caused.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of battery of electric vehicle new copper tip, increases spiral shell
Hole depth, it is to avoid copper tip screw stripped thread phenomenon, extends the use time of battery, reduces the return of goods rate of battery.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of new copper tip of battery of electric vehicle, including a copper tip body, in the copper tip centrally along copper tip
Body longitudinal direction is provided with connecting screw hole, and the copper tip bottom is connected with copper tip base, and the copper tip base is cylinder
Shape structure, covers newly-increased copper tip base holes in the battery, so that the copper tip of new construction can be good fit with middle cover of battery,
The copper tip base top is connected with terminal connecting plate with copper tip body connection, and the terminal connecting plate front end is set
There is connection circular hole, the depth of the connecting screw hole is 9mm, screw hole depth is increased into 9mm by original 5mm, so as to improve spiral shell
The occlusion ability of silk, it is to avoid copper tip screw stripped thread phenomenon.
The height of the copper tip is 10.5mm, and meeting battery appearance requirement, (copper tip is higher by " middle capping ", and size is not
Can exceed that 3mm) on the premise of, increase copper tip base, so as to increase copper tip total height.
The screw model M5, screw hole depth is 9mm.
A diameter of 7mm of the copper tip base, is highly 4.5mm.
The terminal connecting plate front end is provided with a projection, plays positioning action.
Another purpose of the present utility model is to provide a kind of middle cover of battery of the above-mentioned copper tip of cooperation, in the battery
Cover and be provided with copper tip base holes, its size matches with copper tip base.
The beneficial effects of the utility model are：The utility model changes copper tip structure, adds screw hole depth, improves
The occlusion ability of screw, it is to avoid copper tip screw stripped thread phenomenon, extends the use time of battery, reduces the return of goods rate of battery.
