SU402095A1 - CASE FOR PRIMARY BATTERY - Google Patents

Description

one

The invention relates to chemical current sources, namely, a reusable case for a primary battery, for example, a flashlight, the individual elements of which can be replaced with new ones as they fail.

A case for a primary battery is known, comprising a housing with cells for cells and a lid with fixed terminal contacts and inter-element connections made of a spring metal strip.

The disadvantages of the known case are the laboriousness of its manufacture and the lack of reliability of the electrical contacts formed by the inter-element connections fixed in the lid.

The purpose of the invention is to simplify the design and manufacturing technology and to increase the reliability of the connection of elements into a battery.

This goal is achieved by the fact that the inter-element joint is curved at a right angle, the vertical part of which serves as a knife contact, and is horizontal fixed in the lid and provided with a contact tongue bent inwards by 25-30 ° relative to the plane of the lid.

FIG. Figure 1 shows the case for the primary battery with the cover removed and the primary cells installed in the housing;

in fig. 2 - section cover of the case; in fig. 3 - case cover, bottom view; in fig. 4 - mellement compound.

The case is made of an insulating material and consists of a housing 1 with cells for placing the primary elements 2 and the cover 3 with the output contacts 4, 5 fixed on it and the inter-element connections 6.

The inter-element connection 6 is made of a spring metal strip, for example, steel grade X-13, bent at a right angle, with one end, which serves as a blade contact, rounded off and enters the gap between the cell wall of the case and the body of the element 2, and in the center of the other of the end rigidly fixed in the lid, a pin tongue 7 is carved, bent inwards by 25-30 ° with respect to the lid plane.

When the housing 1 is closed with the cover 3, the individual elements 2 are switched into a series-connected battery.

Subject invention
