Abstract

The utility model relates to a self-clamping type case of a lead-acid accumulator. The utility model is composed of a shell, and separating plugs which form each single slot (single separation). The utility model is characterized in that separating plug walls on both sides of each single slot are provided with a plurality of vertical elastic clamping convex fins which can clamp pole plate assemblies. The clamping convex fins are symmetrically distributed in a V shape, are in included angles of 25 DEG to 45 DEG with the separating plug walls, and the width from the clamping convex fins to the separating plug walls is 8 to 20 mm. The utility model can be automatically clamped when the utility model is inserted into the pole plate assemblies. The mounting efficiency is raised, filling separator plates are omitted, and the cost is reduced. A flow path of electrolyte fluid can be especially enlarged. The circulating exchange is smoother, the battery capacity is thoroughly displayed, and the service life of cell polar plates can be prolonged.

Description

Self-clamp type lead-acid battery groove

The utility model relates to a kind of storage battery manufacturing technology, particularly a kind of improvement technology of plumbic acid class battery case.

Have the lead acid accumulator that is used for purposes such as motor vehicle now, its structure comprises battery case, pole plate (make and be the positive/negative plate cluster) and the compositions such as dividing plate between the both positive and negative polarity pole plate as shell.Wherein battery case (is made single groove as required, double flute, three-flute, the structure of a plurality of monomer grooves such as six grooves, each groove produces 2 volts voltages) both sides bulkhead (partition wall) wall of each monomer groove (or claim singly every) on must be provided with several long raised lines, so that play the mobile channeling of acid solution (electrolyte), when each monomer groove of pole plate cluster (being stereotype grid clusters) dress insertion is assembled, need to fill up and jam-pack with the space of dividing plate (special-purpose rubber separator or PVC dividing plate etc. are arranged) with pole plate cluster both sides, so just can play and prevent that vibration of stereotype grid cluster or string from moving, avoid electrode column displacement fracture, and effect such as also can reduce that lead powder comes off.But have following defective with dividing plate filling, space, jam-pack pole plate cluster both sides: the formed acid solution aisle space of long raised line on the bulkhead of monomer groove both sides is limited, if the dividing plate plug tightly can not effectively prevent vibration of stereotype grid cluster or string inadequately and move, and after filling up the space, be unfavorable for circulate electrolyte circulation again, and then be unfavorable for that battery capacity gives full play to (not reaching the requirement of voltage electric weight).

The purpose of this utility model is a kind of improved lead-acid battery groove of design, and it is clamping plate plate cluster automatically, and it is more smooth and easy to allow circulate electrolyte flow, and prolongs battery (pole plate) life-span, and giving full play to of agent battery (pole plate) capacity very arranged.

The utility model is to adopt following technical scheme to realize, it still is made up of shell and the bulkhead that constitutes each monomer groove (single every), it is characterized in that being provided with on the both sides of each monomer groove bulkhead (or claiming partition wall) wall some the vertical elasticity that can clamp the pole plate cluster being clamped protruding wing (or title sheet raised line).

Below in conjunction with accompanying drawing concrete structure principle of the present utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model (schematic cross section).

Fig. 2 is user mode schematic diagram of the present utility model (the vertical section schematic diagram of a monomer groove).

Wherein: 1-battery case shell, 2-monomer groove (or claim single every), 3-bulkhead, 4-elasticity clamp protruding wing (sheet raised line), 5-pole plate cluster (stereotype grid cluster), 6-shedding storage tank (be used for storing come off lead powder with), 7-45 ° chamfering shape transition, 8-arc transition, 9-otch.

With reference to accompanying drawing, the utility model also has following technical characterictic when specific design is made.

One, described every pair clamps protruding wing and is in twos " eight " font and is symmetrically distributed, and every clamp protruding wing 4 and be 25 °～55 ° angles with bulkhead 3 walls, and every width that clamps protruding wing 4 is 8～20mm (according to the design of accumulator plate capacity needs).

Two, every upper end system that clamps protruding wing 4 is chamfering shape transition (chamfering can be about 45 °) and arc transition 8, also is provided with otch 9 between the bottom that clamps protruding wing and the monomer bottom land, helps allowing pole plate cluster 5 insertion and clampings smoothly like this.

The utility model is the plastic raw materials manufacturing of available prior art still, as still using the injection mo(u)lding of copolymerization PP material.

The utility model one is changed into the old-fashioned structure that long raised line is set on the septal wall, (is and use the protruding wing of elastic clamping instead The sheet raised line) replaces it, compared with prior art have the following advantages.

A, in the monomer groove, insert polar plate clusters and install in, the polar plate clusters both sides can be subjected to elastic clip The compressing of tight protruding wing and by Automatic-clamping, thereby needn't carry out jam-pack with dividing plate again, and improved installation effectiveness, Save unnecessary dividing plate and fill, reduced again cost.

B, not only play equally and prevent polar plate clusters vibration or vibration and reduce the effect that lead powder comes off, can also increase The flow channel of electrolyte, the circulation exchange that is conducive to electrolyte is unobstructed, makes the pole plate duty keep good, electric Tankage obtains as far as possible performance, also can prolong (pole plate) battery simultaneously.

C, polar plate number used in the pole plate cluster can be adjusted by measure flexibly, thereby the total capacity of battery itself also can be adjusted easily.

Claims

1, a kind of self-clamp type lead-acid battery groove that is used for storage battery, it is made up of shell and the bulkhead that constitutes each monomer groove, it is characterized in that being provided with on the septal wall of the both sides of each monomer groove some the vertical elasticity that can clamp the pole plate cluster being clamped protruding wing (or title sheet raised line).

2, lead-acid battery groove according to claim 1 is characterized in that described every pair clamps protruding wing and is in twos " eight " font and is symmetrically distributed, and every clamp protruding wing and be 25 °～55 ° angles with the bulkhead wall, and the width of the every protruding wing of clamping is designed to 8～20mm.

3, lead-acid battery groove according to claim 1 and 2 is characterized in that every upper end system that clamps protruding wing is transition of chamfering shape and arc transition, clamps between the bottom of protruding wing and the monomer bottom land and also is provided with otch.
