Abstract

The utility model relates to a battery cover for a thermal battery, which comprises a disc-shaped cover body, six binding posts and an asbestos pad, wherein six holes are uniformly formed on the disc-shaped cover body; the six binding posts are fixedly installed on the six holes in an insulating manner; and the asbestos pad penetrates through the fix binding posts and is positioned on the lower surface of the cover body. The six binding posts contain two ignition head binding posts, two positive binding posts and two negative binding posts. The battery cover has the characteristic that a leveling pad is fixedly installed on the lower surface of the asbestos pad corresponding to the two binding posts. The battery cover has the beneficial effects that as the leveling pad is fixed on the lower surface of the asbestos pad corresponding to the two ignition head binding posts of the cover body, the situation that the tight assembly inside an electric pile is not uniform due to the deviation of the positive and negative binding posts of the thermal battery is avoided, so that the deformation caused by the non-uniform tight assembly inside the electric pile is avoided, and the reliability of the battery is ensured; and the operation is simple and convenient, the design cost is low.

Description

A kind of thermal cell is used battery cover

Technical field

The utility model belongs to the thermal cell technical field of structures, especially relates to a kind of thermal cell and uses battery cover.

Background technology

Thermal cell is that the heating component of usefulness itself is ionic conductor to nonconducting solid-state salt electrolyte heating and melting and self gets into a kind of reserve cell of operating state, and safe and convenient to use, environmental suitability is strong, is the ideal source of device for rapidly starting.

Thermal cell has good environment-tolerance performance for the internal electrode material is solid-state all-sealed structure.Along with the continuous upgrading of modernized device, to the also raising day by day of requirement of thermal cell.At present, the thermal cell battery cover is designed to six binding posts that are uniformly distributed with by four original binding posts, and wherein four adjacent binding posts are used to accomplish the output of two-way voltage, and two other binding post is as igniter head binding post; Battery cover after the design can cause the thermal cell positive and negative terminal amesiality, and the tight assembling degree varies under igniter head binding post and the positive and negative terminal is caused, and causes the inner tight assembling of pile inhomogeneous; For general mechanical condition, such wire laying mode can not make battery be affected, but in the big long mechanical test of magnitude, can cause because of the inner tight assembling of pile is inhomogeneous and make battery generation deformation, influences the battery operate as normal when serious.

Summary of the invention

The utility model provides a kind of positive and negative terminal of avoiding on the battery cover amesiality for solving the technical problem that exists in the known technology; Cause because of the inner tight assembling of pile is inhomogeneous and make battery generation deformation, and a kind of thermal cell that influences the battery operate as normal is used battery cover.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of thermal cell is used battery cover, comprises that the disk shape lid that is uniformly distributed with six holes and insulation are installed in six six roots of sensation binding posts on the hole, passes six roots of sensation binding post and is positioned at the asbestos pad below the lid; In said six binding posts two as igniter head binding post 4, two as positive terminal, two as negative terminal, be characterized in: below two binding post asbestos pads, be fixed with the leveling pad.

The utility model can also adopt following technical characterictic:

Said asbestos pad and leveling pad are loaded into one by rope.

Said leveling pad be positioned at two igniter head binding posts below.

Said binding post is fired on six holes of lid through glass insulator.

Said cover materials is a stainless steel substrates.

Said asbestos pad and leveling pad are asbestos paper.

Said rope is the alkali-free glass fibre rope.

Advantage and the good effect that the utlity model has are:

The utility model is through fixing leveling pad below the corresponding asbestos pad of igniter head binding post of lid; Avoided the thermal cell positive and negative terminal inhomogeneous because of the inner tight assembling of the amesiality pile that causes; Thereby avoid battery because of the inhomogeneous deformation that takes place of the inner tight assembling of pile; Guaranteed the reliability of battery, and easy and simple to handle, design cost is low.

Description of drawings

To be the utility model thermal cell look cross-sectional schematic with the master of battery cover to Fig. 1;

Fig. 2 is the schematic top plan view of Fig. 1;

Fig. 3 be among Fig. 1 A to the rotation sketch map.

Label among the figure is respectively: the 1-lid; The 2-asbestos pad; 3-leveling pad hole; 4-igniter head binding post; The 5-glass insulator; 6-asbestos pad hole; 7-leveling pad; The 8-glass cord.

Embodiment

For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:

A kind of thermal cell is used battery cover, comprises that the disk shape lid that is uniformly distributed with six holes and insulation are installed in six six roots of sensation binding posts on the hole, passes six roots of sensation binding post and is positioned at the asbestos pad below the lid; In said six binding posts two as igniter head binding post 4, two as positive terminal, two as negative terminal.

The innovative point of the utility model: below two binding post asbestos pads, be fixed with the leveling pad; Said leveling pad be positioned at two igniter head binding posts below; Said binding post is fired on six holes of lid through glass insulator; Said asbestos pad and leveling pad are asbestos paper; Said rope is the alkali-free glass fibre rope.

Embodiment:

Shown in Fig. 1-3, prepare thermal cell with lid 1, asbestos pad 2, leveling pad 7 and glass cord 8;

The manufacturing process of the utility model:

1, is uniformly distributed with at a stainless steel disk and gets six holes as lid; Employing can be cut down silk and produce six roots of sensation binding post; Through glass insulator 5 six roots of sensation binding post is fired respectively on six holes of lid, in said six binding posts wherein two be respectively two positive terminals, two negative terminals as igniter head binding post 4, other four;

3, on a circular asbestos paper, process six asbestos pad holes 6 corresponding as asbestos pad with binding post;

4, with asbestos paper process profile as shown in Figure 3, and process in the above with asbestos pad on corresponding two leveling pad holes 3, adjacent two asbestos pad holes as the leveling pad;

5, prepare an alkali-free glass fibre rope;

With glass cord adjacent two asbestos pad holes on the asbestos pad are aimed in two leveling pad holes on the leveling pad earlier, passed the hole with glass cord rope is fastened, the rise plain cushion is fixed on the asbestos pad; The binding post as igniter head binding post is aimed on the lids in two asbestos pad holes that will have a leveling pad hole, sticks on the lid after asbestos pad is passed six roots of sensation binding post, accomplishes the making of thermal cell with battery cover, can directly be used for the assembling of thermal cell.
