Description

[Detailed Description of the Invention] The present invention relates to a plug receiving device for a magnetic plug that connects an electric heating appliance to a power source via a magnetic plug.

Conventionally, the suction plate attached to the plug holder in a plug holder for a magnetic plug is a simple rectangular plate that does not waste material, but it can only be inserted if the plug holder is reversed during assembly work. There is a drawback that it can be easily removed. In addition, to solve this problem, there is a structure in which a notched claw part provided at one end of the suction plate is bent and fixed in a part of the gap in the plug holder, but there is enough room in this gap and the claw part cannot be bent too much. It had some defects such as breakage.

The present invention was devised to eliminate the above-mentioned drawbacks, and includes a suction plate having a hook-shaped claw portion on the end face of a rectangular metal plate, and a plug holder that is perpendicular to the bottom face of the magnetic plug insertion opening. A slit groove for inserting the suction plate is drilled so as to expose one side, and at the bottom of the slit groove, where the end surface of the suction plate comes into contact, there is a shallow recess facing the front side of the plug holder that fits the claw, and a shallow recess that fits the claw part, and a shallow recess that fits the claw part, and a shallow recess that fits the claw part at the bottom of the slit groove where the end surface of the suction plate comes into contact. By providing an operation hole that communicates with the slit groove from the rear side, when the claw part of the suction plate is bent and fixed to the plug holder, the degree of bending is regulated by the shallow recess, preventing breakage.
Another object of the present invention is to provide a structure that improves workability and prevents the suction plate from coming off the plug receiver during assembly.

An embodiment of the present invention will be described above with reference to the drawings.

The structure of the embodiment is as shown in FIGS. 1, 2, and 3, in which 1 is a magnetic plug, and a yoke 5 is provided between two contact pieces 11. 2 is a plug receptacle, and 3 is a suction plate, which is made of a rectangular metal plate and has a hook-shaped claw portion 6 on its end surface. The plug receiver 2 has a slit groove 7 for inserting the suction plate 3, which is perpendicular to the bottom surface of the insertion opening 9 of the magnetic plug 1 and exposed on one side, and a claw portion of the suction plate 3 in the slit groove 7. A shallow recess 8 that fits the claw 6 toward the front side of the plug receiver 2 is provided at the bottom where the end face 6 comes into contact, and an operation hole 12 that communicates with the slit groove 7 from the rear side 12 facing the recess 8. It was established.

The operation of this embodiment will be explained below. To assemble the suction plate 3 to the plug receiver 2, when the suction plate 3 is inserted into the slit groove 7 of the plug receiver 2 in the direction of the arrow A shown in the figure with the claw portion 6 of the suction plate 3 facing down, its end surface will come into contact with the bottom of the slit groove 7. Then, the rear part 1 of the plug receiver 2
When the claw part 6 is pressed and bent in the P direction as shown in the figure with a flat-tipped object such as a flat-tip screwdriver through the operation hole 12 of 1, the tip of the bent claw part 6 comes into contact with the shallow recess 8 and the degree of bending is regulated. be done. In this way, the suction plate 3 is fixed to the plug receiver 2 simply by pressing and bending it, and since the degree of bending is regulated, it will not be bent too much, and the suction plate 3 will be attached to the plug receiver 2 in any direction. It will be less likely to come off. In addition, the insertion port 9 of the magnetic plug 1
One surface of the suction plate 2 inserted through the slit groove 7 which is partially exposed is exposed at the bottom of the insertion opening 9 and comes into close contact with the yoke 5 when the magnetic plug 1 is inserted.

According to the present invention, there is provided a suction plate having a hook-shaped claw portion on the end face of a rectangular metal plate, and a hole in the plug receptacle that is perpendicular to the bottom face of the insertion opening for the magnetic plug and is perforated so as to expose one side thereof. A slit groove for inserting the suction plate, a shallow recess facing the front side of the plug receiver that fits the claw part at the bottom of the slit groove where the end surface of the suction plate comes into contact, and a slit groove facing the recess from the rear side. By providing an operation hole that communicates with the suction plate, when the claw part of the suction plate is easily bent and fixed to the plug holder, the degree of bending is regulated by the shallow recess, and there is no possibility of breakage. It does not come off from the receiver and has the effect of improving work efficiency.
