Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch mounting structure for thin heating devices such as electric carpets and other blankets used for floor heating, and is capable of effectively mounting a switch.

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 is equipped with a connector terminal and is formed in a thin shape similar to a thin heating device, so it is not possible to mount the switch so that the switch's operator is exposed upward. Providing the switch so that it protrudes to the side makes it difficult to fix the switch, and also exposes the screw head, which is undesirable.

In view of the above, the present invention is designed to improve the fixing structure of the switch so that the switch can be mounted inside the cord connection port case.One embodiment will be described below with reference to 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 is made up of a synthetic resin lower case 2a and an upper case 2b, and has a connector terminal 3 provided therein, a connection opening 4, and a lid 5 for opening and closing the connection opening 4. ing. An opening 7 for an operator is formed in one side plate 6 of the lower case 2a, and a pair of vertical walls 8, 8 for holding the switch are integrally formed on the back of this one side plate 6 to fit the shape of both sides of the switch. It is set up. The vertical walls 8, 8 for holding the switch are made of the same synthetic resin as the lower case 2a, are formed thinly and have elasticity, and have a recess 9 in part for fitting with the burring protrusion at the end of the switch board. .
Reference numeral 10 denotes a switch whose height is almost equal to the height inside the cord connection port case 2, and has a base plate 11 with protruding ends on both sides, and a sliding type operator 12 protruding from the surface of the base plate 11. The switch 10 has a pair of vertical walls 8, 8 for holding the switch.
inserted in between. In this case, both ends of the board 11 are press-fitted into the switch board end-fitting recesses 9 and are fitted together, with the other parts having some clearance. Moreover, the operator 12 is made to protrude outside from the operator opening 7 of the lower case 2a. The upper case 2b is attached to the lower case 2a holding the switch 10. Therefore, the outer periphery of the switch 10 contacts the switch holding vertical walls 8, 8, the switch board end fitting recess 9, the bottom plate of the lower case 2a, and the top plate of the upper case 2b, and is stably held.

FIG. 5 shows another embodiment of the present invention, in which the section 13 with the 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 its side plate 14
It has an opening 15 for an operator. In addition, in this embodiment, the operator opening 1 is also provided in the upper case 2b.
There are 6.

In the embodiment shown in FIGS. 1 to 4, the switch vertical walls 8, 8 and the recess 9 for fitting the switch board are provided in the lower case 2a, but these are provided in the upper case 2b.
may be provided. Further, the switch 10 is connected to the board 11
In those that do not use the main body, a protrusion is provided integrally 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 switch mounting structure of the thin heating device of the present invention allows the switch to be stably fixed inside the thin cord connection port case, and does not require screws for fixing. It can be fixed in place, making the fixing work easy. Further, the vertical wall for holding the switch has elasticity and clearance with the switch, and since the switch operator protrudes from the case, external force is likely to be applied thereto, but it absorbs some impact force and is highly safe without causing damage to the switch. Moreover, even if there is some variation in the dimensions of the switch, it can be absorbed, and this has a great practical effect.
