Description

[Detailed description of the invention] The present invention is an electric carpet used for floor heating, etc.

Regarding the switch mounting structure of thin heating devices such as thin blankets, the switch can be mounted effectively.

In general, electric carpets or blankets are thin as a whole, so it is difficult to install a power switch inside a thin heating device such as an electric carpet. was established. However, for operational reasons, it may be more convenient to install the switch in a part of the thin heating device.For this reason, it is recommended to install the switch inside the cord connection port case provided at the edge of the thin heating device. I've been thinking about it. By the way, the cord connection port case has one connector terminal.

It is formed in a thin shape similar to a thin heating device.

It is not possible to mount the switch so that the switch operator protrudes upward, and on the other hand, simply installing the switch operator so that it protrudes to the side makes it difficult to fix the switch and also exposes the screw heads, etc., which is not desirable. do not have.

In view of the above, the present invention has been devised to fix the switch so that the switch can be attached inside the cord connection port case.Hereinafter, one embodiment will be described based on the drawings.

In Figures 1 to 4, 1 is an electric carpet.

Reference numeral 2 denotes a thin cord connection port case provided at a corner of the electric carpet 1. The cord connection port case 2 consists of a synthetic resin lower case 2a and an upper case 2b, and is provided with a connector terminal 3 inside, a connection opening 4,
It has a lid 5 that opens and closes this connection opening 4. One side plate 6 of the lower case 2a is formed with a lower part for an operator, and a pair of switch holding vertical walls 8, 8, which fit the shape of both sides of the switch, are integrally formed on the back of this side plate 6. It is set up. These vertical walls 8, 8 for holding the switch are the lower case 2.
It is made of the same synthetic resin as a, is formed thinly and has elasticity, and has a recess 9 for fitting the end of the switch board in a part. 1
0 is a switch whose height is almost equal to the height inside the cord connection port case 2, and has a board 11 with protruding ends on both sides, and a sliding type operator 12 protruding from the surface of the board 11. The switch 1o is inserted between a pair of switch holding vertical walls 8, 8. in this case.

Both ends of the board 11 fit into the switch board end fitting recesses 9. Further, the operator 12 is made to protrude to the outside from the operator lower part of the lower case 2fL. The lower case 2a holding this switch 10 is covered with the upper case 2b. Therefore, the outer circumference of the switch 10 is in contact with the switch holding vertical walls 8, 8, the bottom plate of the lower case 2&, and the top plate of the upper case 2b,
Maintained stably.

FIG. 5 shows another embodiment of the present invention, in which a member 13 having switch holding vertical walls 8, 8 is made independent from the lower case 2a and the upper case 2b. In this case, the member 13 has an operator opening 15 in its side plate 14. Further, in this embodiment, the upper case 2b is also provided with an opening 16 for the operator.

In the embodiment shown in FIGS. 1 to 4, the switch holding vertical walls 8, 8 are provided on the lower case 2a, but they may be provided on the upper case 2b. Also.

The switch 1o that does not use the substrate 11 is provided with a protrusion integral with the main body. In this case, the switch holding vertical walls 8, 8 are provided with recesses that fit into the protrusions.

As explained above, the thin heater switch mounting structure of the present invention can stably fix the switch inside the thin cord connection port case, and does not require screws for fixing, making the fixing work easy. In addition, the vertical wall for holding the switch has elasticity.
Even if there is some variation in the dimensions of the switch, it can be absorbed and has a great practical effect.
