Abstract
The utility model relates to a battery terminal with a groove structure, applied in the accumulator terminal sealing. Most battery manufacturers currently use two types of conventional terminals: L-type terminals and pole straight-out type terminals. The electrolyte of batteries of the two terminal structures will climb upwards along the battery terminal under the long-term floating charge state, breaks the seal, so that the battery terminal leaks. While the battery terminal of the utility model has a groove structure, namely increasing a plurality of grooves on the external surface of the battery terminal, thereby extending the acid-resistant route of the electrolyte along the battery terminal so that it is not easy for the electrolyte to climb out from the battery terminal; simultaneously sealant is embedded in the groove, which further increasing the resistance force for the climbing of electrolyte along the battery terminal. The battery terminal with a groove structure effectively prevents the climbing out of the electrolyte along the battery terminal and resolves the leaky problem of batteries.
Description
Affiliated technical field
The utility model relates to the accumulator terminal structure, is applicable to valve-control sealed lead acid battery terminal sealing device.
Background technology
The battery manufacturer man adopts two kinds of conventional terminals mostly at present: the straight removing from mould terminal of L type terminal and pole.The battery of these two kinds of terminal structures is under long-term floating charge state, and electrolyte can be climb along terminal, break through sealing after, cause the battery terminal leakage.Although the electrolyte that accumulator terminal spills is considerably less, initial stage does not influence battery capacity, but it may influence the battery outward appearance, and corrosion cell frame, battery connecting line, copper bar and user's various power-supply devices, if can not get for a long time handling, be very easy to cause the accident.Concerning many battery manufacturer men, the terminal sealing problem of valve-control sealed lead acid battery is a problem that urgency is to be solved.
Summary of the invention
At the technology status of present accumulator terminal sealing, for solving terminal leakage problem, the utility model provides a kind of battery terminal.This battery terminal is applied in the terminal sealing device, has prevented that effectively electrolyte from climbing out of along terminal, has solved the problem of storage battery leakage.
The technical scheme that its technical problem that solves the utility model adopts is: battery terminal is designed to groove structure, is exactly to increase the multiple tracks groove at the battery terminal outer surface.This battery terminal with groove structure passes the terminal hole on the battery cover, the electrode column sealing snare is on this battery terminal, spiral hold-down ring compression stage column sealing circle, make sealing ring seal tight terminal, fill the space that terminal, sealing ring, hold-down ring and terminal hole form with fluid sealant, so just constituted the sealing device of battery terminal.Because this battery terminal has groove structure, fluid sealant can be penetrated into inside grooves, has so just prolonged electrolyte along the sour path of climbing of battery terminal, has also increased the resistance that electrolyte climbs out of along battery terminal simultaneously, and electrolyte is not easy to climb out of.Adopt this battery to reach the purpose that prevents the storage battery leakage with groove structure terminal.
The beneficial effects of the utility model are, at the seal aspect of accumulator terminal, have prevented that effectively electrolyte from climbing out of along terminal, have solved the problem of storage battery leakage.And the battery terminal with groove structure is simple in structure, realizes easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a battery terminal sealed structure chart of the present utility model.
1. electrode column sealing circles among Fig. 1 2. have the battery terminal of groove structure, 3. spiral hold-down ring, 4. fluid sealant, 5. battery cover.
Fig. 2 is conventional type terminal sealing structure figure.
1,3,4,5 same Fig. 1,6. conventional type terminal among Fig. 2
Embodiment
In Fig. 1, the sealing device of battery terminal is made up of five parts among the figure, battery terminal (2) with groove structure passes the terminal hole on the battery cover (5), electrode column sealing circle (1) is enclosed within on the battery terminal (2) with groove structure, spiral hold-down ring (3) compression stage column sealing circle (1), sealing ring has just sealed tight terminal (2) like this, fill the space that terminal (2), sealing ring (1), hold-down ring (3) and terminal hole form with fluid sealant (4), so just constituted the sealing device of battery terminal.Because this battery terminal (2) has groove structure, fluid sealant (4) can be penetrated into inside grooves, so just prolonged the climb sour path of electrolyte along battery terminal (2), also increased simultaneously the resistance that electrolyte climbs out of along terminal (2), electrolyte is not easy to climb out of, thereby has solved the leakage problem of battery terminal.
In Fig. 2, different among the structure of terminal and Fig. 1 just, identical among other hermetically-sealed construction and Fig. 1.Terminal among Fig. 2 is conventional type terminal (6), and groove is not with on the surface, and like this, electrolyte can directly climb out of along terminal surfaces, and it is short to climb sour path, and electrolyte is easy to climb out of, thereby causes battery leakage.
This shows that the battery terminal with groove structure of the present utility model is better than the conventional type terminal among Fig. 2 fully among Fig. 1 in the sealing device of accumulator terminal, has prevented that effectively electrolyte from climbing out of along terminal, has solved the problem of storage battery leakage.
Claims (1)
1, a kind of battery terminal, battery terminal passes the terminal hole on the battery cover, the electrode column sealing snare is on battery terminal, spiral hold-down ring compression stage column sealing circle, make sealing ring seal tight terminal, fill the space that terminal, sealing ring, hold-down ring and terminal hole form with fluid sealant, constituted the sealing device of battery terminal, it is characterized in that: battery terminal has groove structure.
