Abstract

The utility model belongs to the technical field of valve regulation lead-acid batteries, and particularly discloses a valve regulation lead-acid battery which comprises an upper cover and a connecting terminal, wherein the connecting terminal is embedded into the upper cover through a lead connecting piece and a built-in lead sheath and is directly welded with the upper cover in a sealed mode. Due to the facts that the connecting terminal is internally arranged into the upper cover and the connecting terminal, the connecting piece and the built-in lead sheath are combined and then welded in the upper cover in one-step molding, adhesive sealing leakage of the connecting terminal of the valve regulation sealed lead battery can be effectively prevented, torque resistance of the terminal can be greatly improved, and at the same time production processes of the battery upper cover can be reduced, production time can be shortened and production efficiency can be improved.

Description

A kind of analysing valve control type lead-acid accumulator battery

Technical field

The utility model relates to the Lead-acid Battery Technology field, is specifically related to a kind of analysing valve control type lead-acid accumulator battery.

Background technology

At present, the valve-regulated sealed lead accumulator product on the market is the rubber seal formula, specifically is exactly that cell cover directly is connected circular copper tip by fluid sealant and seals with battery electrode column; Valve-regulated sealed lead accumulator production process like this is many, length consuming time, and the easy leakage of terminal position, and terminal torque resistant power is little, is prone to fracture.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of analysing valve control type lead-acid accumulator battery is provided.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of analysing valve control type lead-acid accumulator battery comprises loam cake and binding post, and described binding post is embedded in the described loam cake by plumbous connector, built-in plumbous cover, and with the direct seal welding of described loam cake together.

The utility model adopts terminal built-in, a welding fabrication, thus effectively stopped the leakage of the round copper tip rubber seal of valve-regulated sealed lead accumulator formula, greatly improved the torque resistance of terminal.

Description of drawings

Fig. 1 is the perspective view of the loam cake of a kind of analysing valve control type lead-acid accumulator battery of providing of the utility model embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that Fig. 2 is along A-A line profile.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.

Shown in Fig. 1-3, a kind of analysing valve control type lead-acid accumulator battery described in the utility model, the cylindrical binding post 1 that includes battery case loam cake 4 and be connected with described loam cake 4, described cylindrical binding post 1 are by plumbous connector 2, built-in plumbous cover 3 and described loam cake 4 direct seal weldings together.

During making, once cylindrical binding post 1, plumbous connector 2, built-in plumbous cover 3 are connected together sequentially by mould, then by the injection moulding mode this combined connection component is embedded in the battery case loam cake 4, and with loam cake 4 direct seal weldings together.

The utility model is owing to inserting in the described loam cake in the employing binding post, and be welded in the described loam cake with one-shot forming after connector, the built-in plumbous cover combination, thereby effectively stopped the leakage of valve-regulated sealed lead accumulator binding post rubber seal formula, and greatly improved the torque resistance of terminal; Also reduce simultaneously the production process of cell cover, shortened the production time, improved production efficiency.

The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.

Claims

1. an analysing valve control type lead-acid accumulator battery comprises loam cake and binding post, it is characterized in that, described binding post is embedded in the described loam cake by plumbous connector, built-in plumbous cover, and with the direct seal welding of described loam cake together.
