Problems solved by technology

Relatively speaking, the corrosion rate is relatively slow, so it takes a long period of time to produce leakage, and the corrosion rate of the positive electrode is greater than that of the negative electrode, so the leakage of the positive electrode is serious

Embodiment Construction

[0017] The method for preventing the acid seepage of the terminal of the valve-regulated lead-acid battery includes the following steps:

[0018] (1) For the battery that is ready to be plugged with a rubber "O" ring, use a special tool "pressor" to dip the special epoxy resin glue for the battery, drop a drop on the junction of the pole and the battery cover, and then insert the rubber "O" ring. O" ring seal, so that the pole, battery cover, "O" ring and epoxy resin are tightly bonded to form the first sealing barrier;

[0019] (2) Then weld the wire terminal; after the welding is completed, inject epoxy resin glue into the terminal glue groove, the injection amount is roughly 1 / 2 of the volume of the terminal glue groove, forming a second sealing barrier;

[0020] (3) Fill the battery with epoxy resin glue into the terminal glue tank in step (2), put it in an oven at a temperature of 50-60°C for about 30 minutes (accelerate curing), and inject it into the terminal glue tank ...

Abstract

The invention discloses a method for preventing acid seepage of a wiring terminal of a valve-controlled lead acid storage battery, which comprises the following steps: (1) dripping 1 to 2 drops of epoxy resin glue at the combination position of the terminal and a cover of the storage battery ready for the plugging of a rubber 'O'-shaped ring, plugging the rubber 'O'-shaped ring for sealing and making the 'O'-shaped ring tightly contacted with the epoxy resin glue; (2) welding the wiring terminal, filling the epoxy resin glue in a terminal rubber groove till the epoxy resin glue fills half of the volume of the terminal rubber groove after the welding is finished; and (3) placing the storage battery made by the step (1) in an oven at 50 to 60 DEG C for 20 to 40 minutes, and after taking the storage battery out of the oven, filling red and blue or black epoxy resin glue for distinguishing positive and negative poles in the terminal rubber groove till the epoxy resin glue fills the rubber groove up. Production proves that the method can reduce the acid seepage (excluding acid seepage occurring after a period of use by users) rate to zero from the 1.18 percent of the prior wiring terminal not treated by the process.

Description

technical field [0001] The invention relates to a valve-regulated lead-acid battery, in particular to a terminal for a valve-regulated lead-acid battery. technical background [0002] The valve-regulated lead-acid battery is a new type of battery developed in the late 1970s. It is widely used as a backup power source in the communication and electric power industries. It has a history of more than ten years in our country. Due to its low maintenance and no corrosion , No pollution and other advantages, favored by more and more customers, has basically replaced the acid-proof explosion-proof and nickel-cadmium fixed batteries. However, some problems have also been exposed during use, such as the short life of individual batteries, low floating charge voltage and liquid leakage, etc., especially the phenomenon of acid seepage in the terminal is very common. [0003] The common method of sealing the terminal is: first seal the pole and the pole hole on the battery cover with a...
