JPS599109Y2 - Mounting structure of compressor overload relay - Google Patents

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an improvement in a mounting structure for mounting an overload relay used in a compressor such as an air conditioner in a terminal box.

[Technical background of the invention]

Conventionally, the holder used for this type of mounting structure is made of a single wire shaped like an Ω-shape, and an overload relay is fitted into the circular ring in the center to reduce the distance between the two legs. In this way, it was inserted into the hole of the terminal box and held in the hole using the elastic expansion of both legs.

[Problems with background technology]

However, in such a conventional mounting structure, the bending process of the holder is complicated, the unit cost is high, and the workability of the mounting work is also poor.

[Purpose of invention]

The present invention eliminates the drawbacks of the conventional ones mentioned above,
It is an object of the present invention to provide a mounting structure for an overload relay that can be manufactured at low cost and has good workability.

[Summary of the idea]

The present invention consists of a terminal box that is fixed to the outer wall surface of the compressor and has an open front, and a holder that engages with this terminal box to fix an overload relay. The holder has holes formed in each side wall and a communication hole connected to these holes into which a flathead screwdriver type object can be inserted. It has a hole and a pair of holding parts connected to both sides of the central part, and each of these holding parts is bent outward through a rising edge and engages with the hole of the terminal box. At least one of these joint pieces is inclined upward and has a long groove into which a flathead screwdriver can be fitted, and the entire holder is made of a flexible material. It is characterized by being stamped.

[Example of idea]

The present invention will be explained below with reference to embodiments shown in the drawings.

The holder 1 has an annular shape with a circular hole 3 for an overload relay 2 in the center, and holding parts 4 and 5 on both sides.

Then, this holder 1 is instantly shaped by punching from a flexible material.

The holding portion 4 has an upright portion 6, and a rectangular joining piece 7 that is inclined diagonally upward is connected to the outside of this upright portion 6.

A long groove 9 into which a flathead screwdriver 8 can be fitted is formed in the center of the upper surface of the joint piece 7.

On the other hand, the holding portion 5 also has a rising edge 10, and this rising edge 1
A joining piece 11 extending in the horizontal direction is connected to the outside of 0.

Also, both side walls 13 of the terminal box 12 located on the compressor C. 14 have square holes 15 and 16 formed at opposite positions, respectively, and both square holes 15. 16 is made equal to the distance between both joining pieces 7 and 11 of the holder 1.

A communication hole 17 is provided in the center of each square hole 15, 16 to communicate the square hole 15, 16 with the upper part. 18
is formed.

These communication holes 17 and 18 are insertion holes for the flathead screwdriver 8.

Next, the operation of the above-described embodiment will be explained.

After inserting the overload relay 2 into the circular hole 3 of the holder 1, the rising edge 10 of the holder 1 is bent and retreated, and the joint piece 11 of the holding part 5 is inserted into the square hole 16 of the terminal box 12.
Insert inside.

Thereafter, fit the flathead screwdriver 8 into the long groove 9 of the joint piece 7 of the holding part 4, insert this screwdriver 8 into the communication hole 17 of the terminal box 12 from above, and connect the joint piece 7 of the holder 1 to the terminal. Side wall 13 of box 12
lower it to match the inner surface of the

When the joint piece 7 faces the square hole 15 of the terminal box 12, the joint piece 7 is inserted into the square hole 15 due to its elasticity, and the holder 1 is connected to the terminal box 11 of both the holding parts 4, 5. 12 square holes 15 and 16, the overload relay 2 is held and stabilized.

In addition, in the embodiment described above, two types of holding parts 4 and 5 are used.
Although the holding portions 4 are provided on both sides, the holding portions 4 may be provided on both sides.

[Effect of idea]

Since the mounting structure of the overload relay according to the present invention is constructed as described above, the holder can be joined by simply fitting a flathead screwdriver into the long groove of the holder and pressing it along the communication hole of the terminal box. The piece can be fitted into the hole in the terminal box, making it easy to work with, and since the holder is stamped from a flexible material, it can be manufactured efficiently and at low cost.
