Problems solved by technology
For example, the authorized announcement number is CN 1134076C, which is called the battery terminal sealing method and structure patent. By injecting thermoplastics in the middle of the battery terminal and using a sealing ring to seal the upper part of the battery terminal, the sealing effect between the sealing ring and the groove cannot be achieved. Guaranteed and less reliable due to aging etc.
With the advancement of formula and other technologies and the market requirement that the energy storage battery can reach a service life of 10-15 years, the current sealing method cannot reliably meet the demand

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings.
[0027] Such as figure 1 As shown, a battery terminal pole 2 sealing method comprises the following steps:
[0028] Step 1: Cover the outer side of the terminal pole 2 with a layer of plastic to form the rubber coating layer 3, leaving a gap of at least 1 mm between the rubber coating layer 3 and the top of the pole socket of the terminal pole 2;
[0029] Step 2: hot-melt sealing the battery end cover, and hot-melt sealing the relative position of the first protrusion 11 on the battery end cover and the adhesive layer 3;
[0030] Step 3: Use a plastic welding gun to soften the intersection between the adhesive layer 3 and the battery end cover 1, fill with hot-melt plastic and cool;
[0031] Step 4: Fill sealant between the protrusion 11 on the battery end cap and the battery pole.
[0032] The material of the adhesive layer 3 and the battery end c...

The invention provides a method for sealing a battery terminal post, comprising step 1: coating the outer side of the terminal post with a layer of plastic, leaving a gap of at least 1 mm between the rubber coating layer and the top of the post socket of the terminal post; step 2: Hot-melt seal the battery slot cover, and hot-melt seal the relative position between the battery slot cover and the adhesive layer; Step 3: Use a plastic welding gun to soften the intersection position between the adhesive layer and the battery end cover, and fill the intersection position with hot melt Form the plastic and cool it down; step 4: pour sealant between the protrusion on the battery slot cover and the battery pole. Compared with the prior art, the invention can ensure the reliable sealing of the battery terminal pole and improve the service life of the battery.
Description
technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a battery terminal post sealing method and structure. Background technique [0002] Most of the current energy storage batteries use PP plastic casings, which are sealed by welding lead bushings, which can ensure reliable sealing within 5-7 years. For example, the authorized announcement number is CN 1134076C, which is called the battery terminal sealing method and structure patent. By injecting thermoplastics in the middle of the battery terminal and using a sealing ring to seal the upper part of the battery terminal, the sealing effect between the sealing ring and the groove cannot be achieved. Guaranteed and less reliable due to aging etc. With the advancement of formula and other technologies and the market requirement that the energy storage battery can reach a service life of 10-15 years, the current sealing method cannot reliably meet the demand.
