Abstract

The utility model discloses a lead-acid storage battery. The lead-acid storage battery has the beneficial effects that a sealing layer seals a battery case and a battery cover, and an exposed welding part of a pole is electrically communicated with a battery terminal, so that the acid mist generated in a battery using process can not leak out of the battery because of being sealed by epoxy resins near the battery terminal, thus avoiding corrosion of the terminal or a locomotive caused by acid leakage and protecting the lead-acid storage battery and the locomotive.

Description

Lead acid accumulator

Technical field

The application relates to field of batteries, relates in particular to a kind of lead acid accumulator.

Background technology

Lead acid accumulator is that a class is safe, electric performance stablity, low cost of manufacture, application extensively and resource recycling energy products that can low-cost regeneration.In recent years, along with the raising day by day of world energy sources expanding economy and living standards of the people, motorcycle obtained promotion and application widely as recreation tool in the rural area of China, and motorcycle is also progressively increasing sharply to the demand of lead acid accumulator.

In the production process of lead acid accumulator, battery terminal welding is its important component part, the end points that its conduct is connected with the electricity consumption facility, and requirement can be born certain high current charge-discharge, guarantee the battery maximum power, not generate heat, do not corrode and safe and reliable.In traditional lead acid accumulator, because the battery terminal encapsulate is poorly sealed, the acid mist that battery in use produces can be climbed to along the battery terminal surface outside batteries (being commonly referred to as the sour problem of climbing), causes the terminal corrosion, can corrode locomotive when serious.

Summary of the invention

The application provides a kind of lead acid accumulator, to avoid producing the sour problem of climbing in the battery use procedure, protection lead acid accumulator and locomotive.

The application provides a kind of lead acid accumulator, comprise: battery case, be arranged at described battery case inner and have pole battery electrode group, cover at described battery case top and have the battery cover of battery terminal, and the sealant that is wrapped in described battery case and battery cover outside, be exposed to electric connection between the weld part of described sealant outside and battery terminal on described pole.

The application's beneficial effect is:

By a kind of lead acid accumulator is provided; sealant seals battery case and battery cover; and electric connection between the exposed weld part of pole and battery terminal; thereby; the acid mist that produces in the battery use procedure can not climbed to outside batteries because of near the epoxy sealing battery terminal; thereby avoided the terminal or the locomotive etching problem that cause because climbing sour problem, protected lead acid accumulator and locomotive.

Description of drawings

Fig. 1 is the first stereogram of the lead acid accumulator of the embodiment of the present application;

Fig. 2 is the second stereogram of the lead acid accumulator of the embodiment of the present application.

Embodiment

By reference to the accompanying drawings the application is described in further detail below by embodiment.

Please refer to Fig. 1 and Fig. 2, the lead acid accumulator of the embodiment of the present application, comprise: battery case 1, be arranged at battery case 1 inner and have pole battery electrode group 2, cover at battery case 1 top and have the battery cover 3 of battery terminal 31, and the sealant (because of transparent not shown) that is wrapped in battery case 1 and battery cover 3 outsides, be exposed to electric connection between the weld part 21 of sealant outside and battery terminal 31 on pole.

Particularly, sealant can adopt epoxide resin material, thereby can realize sealing effectiveness cheaply.And after sealing, can greatly improve the anti-seismic performance of lead acid accumulator.

Battery electrode group 2 comprise intersecting positive plate 22, negative plate 23, be arranged at dividing plate 24 between positive plate 22 and negative plate 23, with the positive bus 25 of the lug electric connection of positive plate 22, and with the negative bus of the lug electric connection of negative plate 23.

Positive bus 25 and negative bus direct casting are welded with above-mentioned pole.

Battery terminal 31 is placed in the battery cover terminal groove of battery cover 3.Can reduce the crooked of battery terminal 31 like this, greatly promote the aesthetic of storage battery.

Be injected with electrolyte in battery case 1.

The manufacture method of above-mentioned lead acid accumulator is mainly as follows:

At first, negative plate 23, dividing plate 24, positive plate 22 spaces arrangement cast weldings form battery electrode group 2, weld bus-bar on battery electrode group 2;

Secondly, be welded into the type pole at the bus-bar direct casting;

Then, with the battery electrode group of above-mentioned moulding battery case 1 and battery cover 3 assemblings, battery case 1 and battery cover 3 are got up by epoxy sealing, form sealant;

Then, use milling cutter that the weld part 21 of the pole at battery case terminal groove place is milled out, and adopt the flatiron welding manner that the weld part 21 of pole is welded together with battery terminal 31; Mill out the weld part 21 that comes and expose metallic luster, weld together the welding quality that can improve battery terminal 31 with battery terminal 31, guarantee the good heavy-current discharge performance of lead acid accumulator;

At last, inject electrolyte, form lead acid accumulator.

Above content is the further description of the application being done in conjunction with concrete execution mode, can not assert that the application's concrete enforcement is confined to these explanations.For the application person of an ordinary skill in the technical field, under the prerequisite that does not break away from the application's design, can also make some simple deduction or replace.
