Abstract
The invention provides a copper core terminal of a lead-acid storage battery, and relates to the lead-acid storage battery structure. The terminal comprises a main body and an upper cap which are arranged along the same coaxial line; the top parts of the main body and the upper cap are connected; an annular cavity is formed below the connecting position; notches are formed in the side wall of the periphery of the cavity; side ears are arranged outside the main body; and a base plate is arranged at the bottom. By adoption of the copper core terminal provided by the invention, the usage amount of the copper material is reduced, so that the cost is lowered; meanwhile, the contact area between the copper core and a lead polar column is enlarged, so that torsion resistance and tensile strength are improved; and in addition, air exhausting in the casting and welding processes is facilitated, and burn down of the terminal is prevented, so that the product quality is ensured.
Description
Technical field
The present invention relates to a kind of lead-acid accumulator copper core terminal, belong to lead-acid accumulator field.
Background technology
Development along with the communications industry, the granting of 4G operation licence plate, the construction of communication base station is being accelerated in each big communication operation commercial city, meanwhile, the standby electricity lead-acid accumulator demand in base station is increasing, requiring more and more higher, especially the performance of battery and price, this is a great challenge to the manufacturing cost of accumulator.The terminal major part of communication lead-acid accumulator is copper tip at present, and existing integrally-built copper tip copper consumption is relatively big, and price is the most of a relatively high.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of reduction copper core material cost, increase the most again the contact area of copper core and lead terminal post, improve the lead-acid accumulator copper core terminal of battery serviceability.
The technical scheme is that lead-acid accumulator copper core terminal, cylindric, there is threaded endoporus at center, its improvements are that copper core terminal is made up of trunk and the upper cap of coaxial line, upper cap is connected with trunk top, has the toroidal cavity between upper cap and trunk below coupling part, and the sidewall that cavity is peripheral has gap, pick up the ears outside trunk, bottom trunk, have chassis.
Described upper cap and trunk top coupling portion thickness a=3～5mm, sidewall thickness b=1～1.5mm that cavity is peripheral.
The present invention is applicable to communication lead-acid accumulator, copper piece die casting form, and has cavity between copper core top and upper cap, reduces copper material consumption, reduces cost.Copper core and lead terminal post contact area increase, and improve antitorque resistance to tension, reduce the voltage drop of copper core electrode post, decrease the heating of copper core during battery high-multiplying power discharge, it is ensured that the reliability that battery uses.The architectural feature of the present invention and relative dimensions can guarantee that the intensity of copper core, the aerofluxus during facilitating copper core electrode post to water casting, protect the lead of inside not subsided by scorification, it is ensured that product quality during pole freezes.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Referring to the drawings, the present invention is formed by copper piece die casting, and upper cap 1 and trunk 3 by coaxial line are constituted, and upper cap is connected with trunk top, have the toroidal cavity 6 between upper cap and trunk below coupling part, and cavity outer wall is provided with the gap 2 of two aerofluxuss.Trunk is hollow-core construction, is internally threaded, it is simple to connecting line connects, and is symmetrically arranged on two with 2 pick up the ears 4, in embedding lead terminal post, the moment of torsion that increase copper core horizontally rotates, and the chassis 5 bottom trunk embeds in lead terminal post, increases longitudinal tensile strength of copper core.Upper cap and trunk top coupling portion thickness a=4mm, the sidewall thickness b=1.2mm that cavity is peripheral.
Claims (2)
1. a lead-acid accumulator copper core terminal, cylindric, there is threaded endoporus at center, it is characterized in that copper core terminal is made up of trunk and the upper cap of coaxial line, upper cap is connected with trunk top, has the toroidal cavity between upper cap and trunk below coupling part, and the sidewall that cavity is peripheral has gap, pick up the ears outside trunk, bottom trunk, have chassis.
2. lead-acid accumulator copper core terminal as described in claim 1, is characterized in that described upper cap and trunk top coupling portion thickness a=3～5mm, sidewall thickness b=1～1.5mm that cavity is peripheral.
