Abstract

The utility model discloses a lead-acid storage battery pole hole which comprises a cover body, wherein a groove is formed in the cover body, a through hole for a pole to pass through is formed in the center of the groove, a step is formed in the bottom of the pole, a foam gasket is sleeved on the step, and a gap between the pole and the through hole is sealed through high-temperature hot melting of the foam gasket. The top welding of utmost point post has binding post, and utmost point post bottom is equipped with the step, and fenestrate bottom is equipped with the slant opening, and the size in clearance between opening and the utmost point post is 0.1mm-0.5mm, the edge tilt up of step, the diameter of foam gasket is less than the diameter of step, and utmost point post and fenestrate clearance are sealed through foam gasket high temperature hot melt. When the wiring terminal is welded, the foam gasket can be melted and flow into a gap between the rubber groove and the pole by high temperature generated by welding, so that sealing is realized; through the trapezoidal perforation of cross section, make things convenient for utmost point post to pass, and because there is the slope at the step edge during the welding for the foam gasket card is gone into in the clearance of gluing groove and utmost point post.

Description

Pole column hole of lead-acid storage battery

Technical Field

The utility model relates to the technical field of storage battery production, in particular to a lead-acid storage battery pole column hole.

Background

In order to prevent the electrolyte in the battery jar from leaking outwards, the existing method is to sleeve an O-shaped sealing ring on the pole, compress and flatten the O-shaped sealing ring, inject sealant, and further seal, which is easy to cause the sealing ring to be assembled in place or deformed during assembly, so that the sealing effect is poor, and the phenomena of glue leakage and acid leakage are generated.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a lead-acid storage battery pole hole to solve the problems in the background technology.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a lead acid battery utmost point post hole, includes the lid, be equipped with the recess on the lid, recess center department is equipped with the perforation that is used for utmost point post to pass, utmost point post bottom is equipped with the step, the cover is equipped with the foam gasket on the step, utmost point post and perforated clearance are sealed through foam gasket high temperature hot melt.

Preferably, the top of the pole is welded with a wiring terminal.

Preferably, the bottom of the pole is provided with a step.

Preferably, the bottom of the through hole is provided with an oblique opening.

Preferably, the size of the gap between the opening and the pole is 0.1mm-0.5 mm.

Preferably, the edge of the step is inclined upward.

Preferably, the diameter of the foam pad is smaller than the diameter of the step.

Preferably, the clearance between the pole and the through hole is sealed by a foam gasket through high-temperature hot melting.

Compared with the prior art, the utility model has the following beneficial effects:

firstly, when the wiring terminal is welded, the foam gasket can be melted and flows into a gap between the rubber groove and the pole by high temperature generated by welding, so that sealing is realized.

The utility model further provides a welding method for the pole, and the welding method is characterized in that the through hole with the trapezoidal cross section is convenient for the pole to pass through, and the foam gasket is clamped into a gap between the rubber groove and the pole due to the fact that the edge of the step is inclined during welding.

Drawings

FIG. 1 is a schematic structural view of the present invention;

shown in the figure: 1. a cover body; 2. a groove; 3. a pole column; 4. a foam gasket; 5. a wiring terminal; 6. perforating; 7. and (4) opening.

Detailed Description

To further illustrate the technical means and effects of the present invention for achieving the intended purpose of the utility model, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

The lead-acid storage battery pole hole as shown in fig. 1 comprises a cover body 1 (only one end related to the utility model is cut out in the drawing, and not all ends are shown), a groove 2 is arranged on the cover body 1, a through hole 6 for a pole 3 to pass through is arranged in the center of the groove 2, an oblique opening 7 is arranged at the bottom of the through hole 6, and the size of a gap between the opening 7 and the pole 3 is 0.1mm-0.5 mm. The welding of the top of utmost point post 3 has binding

post

5, 3 bottoms of utmost point post are equipped with step 31, the edge tilt up of step 31, the cover is equipped with foam gasket 4 on the utmost point post 3 on the step 31, the diameter of foam gasket 4 slightly is less than the diameter of step 31, utmost point post 3 and opening 7's clearance are sealed through 4 high temperature hot melts of foam gasket.

The use principle is as follows:

the cover body is pressed down, the pole column penetrates through the through hole, the foam gasket on the step at the bottom of the pole column is tightly connected with the through hole, at the moment, the wiring terminal is welded, the foam gasket is melted at high temperature when the wiring terminal is welded, the foam gasket is converged towards the middle part and is clamped into the through hole and an opening gap of the pole column, sealing is achieved, the sealing effect is good, an O-shaped ring is omitted, and the cost is further reduced.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
