CN201946512U - Inner buckling structure of electromagnetic relay casing - Google Patents

Abstract

The utility model discloses an inner buckling structure of an electromagnetic relay casing, which comprises the casing and a base board. An inner buckle with a triangle slope section is arranged at the lower end of the casing inner wall, a buckle hole is arranged on the lateral side of the base board, the inner buckle and the inner buckle hole are in a snapping fit. The inner buckling structure of the electromagnetic relay casing is capable of effectively fixing the casing and the base board by installing the inner buckle at the lower end of the casing to be snapped with the buckle hole at the lateral side of the base board so as to save glue and create economic benefits for enterprises.

Description

Buckle structure in a kind of electromagnetic relay shell

Technical field:

The utility model relates to the electric equipment field, buckle structure in a kind of specifically electromagnetic relay shell.

Background technology:

Electromagnetic relay mainly partly partly is made up of with output input.This two part mainly comprises: the moving and static contact spring piece of the coil of input, yoke, division board, base plate, iron core, armature, output.When coil adds certain voltage or electric current at the two ends of its terminal pin, the coil of energising will produce magnetic flux, magnetic flux by iron core, yoke be lost, armature and certain working gas gap produce attraction, thereby drive break-make and conversion that movable contact spring is connected the real circuit of static contact spring piece.

Because most for sealing is connected between the base plate of existing product and the shell, the long-time use has situation about coming off, and the cost of glue is higher, so imagine and provide a kind of new structure to replace.

Summary of the invention:

For solving the problem that prior art exists, the utility model spy provides buckle structure in a kind of electromagnetic relay shell, by buckle in install the shell lower end, clamp the frame mode that cooperates with the block button hole of base plate side, can effectively shell and base plate be fixed together, saved and used glue, for enterprise has created economic benefit.

The technical solution adopted in the utility model is:

Buckle structure in a kind of electromagnetic relay shell, comprise shell, base plate: the outer casing inner wall lower end is equipped with interior buckle, and interior buckle is that the cross section is leg-of-mutton slope, and the base plate side is provided with block button hole, and described block button hole clamps with interior buckle and cooperates.

Advantage of the present utility model is:

The utility model clamps the frame mode that cooperates by buckle in install the shell lower end with the block button hole of base plate side, can effectively shell and base plate be fixed together, and has saved and has used glue, for enterprise has created economic benefit.

Fig. 1 is the utility model structural representation;

Embodiment:

Buckle structure in a kind of electromagnetic relay shell, comprise shell 1, base plate 2: shell 1 inwall lower end is equipped with interior buckle 3, and interior buckle 3 is leg-of-mutton slope for the cross section, and base plate 2 sides are provided with block button hole 4, and described block button hole 4 clamps with interior buckle 3 and cooperates.

Claims (1)

1. the interior buckle structure of electromagnetic relay shell comprises shell, base plate, and it is characterized in that: the outer casing inner wall lower end is equipped with interior buckle, and interior buckle is that the cross section is leg-of-mutton slope, and the base plate side is provided with block button hole, and described block button hole clamps with interior buckle and cooperates.
