Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electric heating device whose main body is in the form of a sheet, such as an electric carpet, and in particular to a control box with a switch etc. attached to a connector attached to the main body. This invention relates to an electric heating device that has been improved so that it can be attached and detached.

[Technical background of the invention and its problems]

For electric heating devices such as electric carpets,
A case-like control box including a power switch and the like is attached to the main body of the carpet. Conventionally, there are two types of control boxes: one in which the control box is removably connected to an outlet on the carpet side via a connection cord, and the other in which the control box is fixedly attached directly to the carpet without the connection cord.

However, in the former case, since there is a connection cord that connects the control box to the carpet side, this connection cord gets in the way of pedestrians and is an eyesore, and if the control box is placed outside the carpet, it is difficult to move away from the carpet. Therefore, there is a problem in that it is difficult for users who are on the carpet to operate the power switch, etc. In the latter case, when the user wants to use the carpet as a simple carpet without a heating function in the summer, etc., a relatively large control box is installed on the carpet. There is a problem that the control box becomes unsightly or gets in the way.

In order to solve these problems, modern connectors are installed on the carpet, and a connecting piece is provided on the control box, and this connecting piece is inserted and removed from the side of the connector horizontally, so that the control box can be attached to the carpet. It is being considered to have a structure that can be directly attached to and detached from the body.

However, in this case, when the control box is attached to the connector, the control box floats up and its bottom surface becomes separated from the installation surface of the connector, so the control box is difficult to maintain in a horizontal state due to its own weight and tilts downward. As a result, the connection piece of the control box tends to be pulled out from the connection insertion opening of the connector. For this reason, there is a risk that the connection between the control box and the connector may become uncertain, and furthermore, if the control box is accidentally stepped on, the connection piece may become deformed or fall out of the connection insertion hole. be.

[Purpose of invention]

Therefore, the object of the present invention is to provide a connector which is provided at the peripheral edge of a sheet-like main body by sandwiching this edge and has a connection insertion opening on one side, and a connector which is formed thinner than this connector and has a connection insertion opening on one side. In a device equipped with a control box that has connecting pieces and switches to be inserted and is attached and detached from the outside of the main body, the control box does not tilt with respect to the connector, and even if the control box is accidentally stepped on. To provide an electric heating device that can secure a reliable connection between a control box and a connector without deforming a connecting piece, and allows easy connection of the control box to the connector.

[Summary of the idea]

The present invention provides a connector with a recessed receiving part that is parallel to the connection insertion opening formed on one side of the connector and is deeper than the insertion opening and is open on the lower surface and the one side of the connector. A control box having a switch etc. is provided with a connecting piece and an auxiliary protruding piece in parallel with each other, the auxiliary protruding piece is formed longer than the connecting piece, and legs are provided protruding from the lower surface of the control box,
When attaching the control box to the connector, before inserting the connection piece of the control box into the connection insertion hole of the connector, insert the auxiliary protrusion into the receiving part to position the connection piece and the insertion hole, and to prevent the control box from tilting relative to the connector due to its own weight, etc., and to ensure that the connector and control box are securely connected and that the control box is not accidentally stepped on. It is designed to be able to deal with any situation.
