Description

A wire switch housing

[technical field]

The utility model relates to a wire switch shell used for electric lamp flexible wire switch control.

[Background technique]

At present, cord switches are widely used in the control switches of table lamps, bedside lamps, etc. in homes and hotels. The commonly used cord switch housings include bottom shells and face shells, as well as bottom shell connecting columns and faces arranged at the four corners or both ends of the shell. There are corresponding wire grooves and button holes in the shell. The connection between the bottom shell and the front shell is connected by screws from the bottom of the bottom shell connecting pin through the face shell connecting pin. It is very inconvenient to connect. And it is easy to screw the connecting column, the cost is also high, and it is not easy to popularize and use.

[utility model content]

The purpose of the utility model is to overcome the above disadvantages and provide a wire switch housing that is convenient in connection, low in cost and easy to popularize and use.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model relates to a wire switch housing, which includes a shell composed of a bottom shell and a face shell, and bottom shell connecting posts and face shell connecting posts arranged at the four corners of the shell, and there are corresponding wire grooves in the shell And the button hole and the through hole respectively provided at both ends of the housing for the power cord to enter and exit, it is characterized in that: the connecting column of the bottom shell is provided with a hollow hole, and the connecting column of the face shell is an interference fit with the hollow hole Solid column, the connecting column of the face shell is inserted in the above hollow hole;

A wire switch housing as described above is characterized in that the connecting column of the face shell is integrally injection-molded with the face shell, and the connecting column of the bottom shell is integrally injected with the bottom shell;

A wire switch housing as described above is characterized in that the hollow hole on the connecting post of the bottom case is cylindrical, and the outer diameter of the connecting post on the front case is 0.1-0.3 mm larger than the diameter of the hollow hole.

The beneficial effects of the utility model are:

1. There is a cylindrical hollow hole on the connecting column of the bottom shell, and the connecting column of the surface shell is stuck in the above hollow hole, so as to play the role of connecting the bottom shell and the surface shell. The structure is simple and the connection effect is good.

2. The bottom shell and the top shell are made of plastic injection molding. The top shell connection column is injection-molded with the top shell, and the bottom shell connection column is also injection-molded with the bottom shell. When fastening, just put the bottom shell and The face shells are aligned and pressed together to complete the installation, which is very convenient, low in cost and easy to use.

[Detailed ways]

As shown in the figure, a wire switch housing includes a shell composed of a bottom shell 1 and a face shell 2, and bottom shell connecting posts 3 and face shell connecting posts 4 arranged at the four corners of the shell. The wire groove and the button hole 6 and the through holes 7 that are respectively provided at both ends of the housing to supply the power cord in and out, the bottom shell connecting column 3 is provided with a hollow hole 31, and the surface shell connecting column 4 is connected with the hollow hole 31 A solid column with an interference fit, the surface case connection column 4 is inserted into the hollow hole 31 so as to connect the bottom case 1 and the surface case 2 .

Wherein, the hollow hole 31 on the connecting post 3 of the bottom case is cylindrical, and the outer diameter of the connecting post 4 of the surface case is 0.1-0.3 mm larger than the diameter of the hollow hole 31 . In the utility model, the connecting column 3 of the bottom shell and the connecting column 4 of the face shell are all made of plastic, and have a certain resistance to deformation. The connecting column 4 can be closely matched without loosening, and has a simple structure and good practical effect.

In the utility model, the bottom shell 1 and the face shell 2 are formed by injection molding of plastic, the face shell connecting column 4 is integrally injected with the surface shell 2, and the bottom shell connecting column 3 is also connected with the bottom shell. The shell 1 is injection-molded into one body, and when fastening, only the bottom shell 1 and the top shell 2 need to be aligned and pressed together, which is very convenient for installation, low in cost, and convenient for popularization and use.
