SU1753500A1 - Multicontact commutation device - Google Patents

Abstract

Usage: electrical engineering, namely in switching devices. Essence: the presence of at least one additional partition allows at least two times increase in the number of magnetically controlled sealed contacts installed in the housing. 3 il.

Description

The invention relates to electrical engineering and may find application in control and communication systems.

A multi-contact switching device is known, comprising a housing, an excitation winding and a series of reed switches of type CEM-1.

In the known device, sealed contacts type KEM-1 are located inside the coil with a winding. Rubber pipes and plastic pads are put on the conclusions of the reed switches, which prevent horizontal movement of the reed switches.

The known structure has limited reliability and low manufacturability during assembly.

The closest in technical essence to the proposed is a multi-contact reed switch.

The known reed switch contains at least two pairs of contact parts, the terminals of which are placed in holes made in the opposite ends of a flat detachable body consisting of a base and a cover.

The base and the lid are made with flanges located along the perimeter in the plane of the section of the housing, and the apertures are formed by grooves formed opposite one another in the flanges of the lid and the base. Magnetically controlled sealed contacts, for example, reed switches of type KEM-1, can be placed in this case.

However, the known device has limited operational capabilities and limited manufacturability.

The purpose of the invention is to expand the operational capabilities and increase manufacturability in production.

This goal is achieved by the fact that in a multi-contact switching device containing a flat detachable case and magnetically controlled sealed contacts located in it, said flat detachable body consisting of a bottom base and a cover, and a non-magnetic sealed contacts are located inside the case so that their leads are located in holes made

opposite ends of the housing, the open hole repeating the shape of the terminals of the agitucated sealed contacts, these holes are formed by grooves made one on the other side of the flat split housing, the case is equipped with at least one partition and additional magnetic contacts sealed contacts, the partition is made in the form of the frame, the perimeter of said partition is chosen to be equal to the perimeter of the lid or the base of the body; that are crowded at its ends, said T-heading is installed between the base and the cover of the flat split housing in such a way that said holes are formed at the ends of the housing. -

The presence of at least one additional barrier allows at least two times the number of magnetically controlled sealed contacts installed in the housing.

Figure 1 shows a multi-contact switching device; Fig 2 - base (and cover); Fig 3 - partition

The multi-contact switching device contains a detachable housing consisting of a base 1, a partition 2 and a cover 3. The housing along the connector lines The base - the partition and the partition - the cover has holes (in opposite ends of the housing). Pins 4 and 5 of the magnetically controlled sealed contacts 6 are placed in these holes.

The base 1, the partition 2 and the cover 3 are made of solid dielectric.

The assembly of the multi-contact switching device is performed as follows. , „-

The grooves of the base 1 are smeared with glue (for example, VK-9 glue), magnetic contacts are sealed into the grooves 6, the glue surface of the base is smeared with glue

Magnetically controlled sealed contacts 6 are tanned into the upper grooves.

The split surface and the grooves of the cover 3, which is mounted on the partition 2, are lubricated with glue. The housing parts are compressed in a special device. In practice, the structure of the switching device provides

sealing (optional).

The device may contain any number of partitions.

In comparison with the known, the proposed multi-contact switching device has extended
