SU372596A1 - HERMETIC CHEMICAL SOURCE OF CURRENT - Google Patents

Description

one

Known sealed chemical current source, containing an elastic body with a collar, opposite electrodes with output borny and electrolyte.

They are sealed either by using special gaskets, or by means of various sealants and pastes that do not provide reliable sealing during long periods of operation.

In addition, their disassembly during operation cannot be carried out, which excludes the possibility of replacing individual components.

In the present invention, in order to increase the reliability and simplify the assembly, it is proposed to make the shoulder in the form of semirings connected by straight sections.

FIG. 1 depicts the proposed chemical current source; in fig. 2 - the same, top view.

Sealed chemical current source consists of a single rubber body 1, a pack of plates 2 connected to Born 3, 4. The sealing element consists of two annular shoulder 5 connected by flat shoulder 6 forming the mounting hole 7. The plates are mounted and dismounted through the mounting hole 7 elements, while the sealing bead, due to the elastic properties of the rubber, is able to stretch, which allows the plates to be mounted with a slightly larger size than the hole. The clamp consists of two halves 8, in which two half-ring grooves are made under the sealing shoulder.

The chemical current source is sealed when the two halves of the clamp are tightened with screws 9, which tighten

rubber beads to a certain value, given the design dimensions of the clamp. Due to the deformation of the rubber bead, when the clamp is crimped, contact stresses are created on the sealing surface.

(due to the elastic properties of rubber), which ensure the tightness of the current source.

When operating a chemical current source as an independent cell, it can

be placed in a rigid casing of lightweight material in order to prevent deformation under the action of internal overpressure. Using a chemical source

There is no need for an individual rigid case in the battery because the individual cells in the battery are placed in a common case - a container in which they are pressed against each other, protected from deformation and damage.
