DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A grounding cord connecting device for an antistatic mat according to the present invention will be described in detail below with reference to an embodiment shown in the drawings. In the static eliminator mat according to the present invention, the overlock yarns on the mat surface and the peripheral portion of the mat are made to contain the conductive material such as carbon, iron or the like or the fibers, so that the mat surface and the peripheral portion have conductivity, and the entire surface of the mat is It has the function of two conductors. When the human body comes into contact with the static elimination mat, the static electricity charged on the human body flows to the side of the static elimination mat. As shown in FIG. 1, the static elimination mat according to the present embodiment includes a pile 12 on the surface of the mat and an overlock thread 13 forming a peripheral portion of the mat 12 with conductive fibers so that the pile 12 and the overlock 1 can be formed.
3 is electrically connected, and the entire surface of the static elimination mat 11 is made into one conductor. Incidentally, the static elimination mat is not limited to the above example, and may be anything as long as the entire surface of the mat acts as one conductor.

The ground cord connecting device 2 for this static elimination mat
As shown in FIGS. 1 and 2, 0 has a terminal 22 for connecting the conductive plate 21 and the earth cord 14. The conductive plate 21 can be easily bent with a fingertip or other simple means, and after the peripheral edge of the mat 11 is sandwiched and pressed, the conductive plate 21 sandwiches the peripheral edge of the mat 11.
It is preferable that the end portion has a hardness that does not easily open.
In this embodiment, a longitudinal tooth 5 is provided with a wave-shaped tooth 23 at the end.
× An iron plate having a width of about 5 cm was used. In addition to iron, copper, tin plate, stainless steel plate, etc. can be used as the material of the conductive plate 21. Among them, the stainless steel plate is highly corrosive, and thus the rust does not easily impair the conductivity, which is preferable. The terminal 22 is joined to one end of the conductive plate 21.

As the terminal 22, it is possible to use a conventionally known one such as a metallic one, a plastic molded one in which a metal piece is attached to a plug insertion portion. In this embodiment, as shown in FIGS. 1 and 2, the earth cord 1
4 is a thin plate-shaped plug 15 with a concave portion in the center

The plug 15 at the end of the earth cord 14 may be connected from either of the both ends. In addition, the connecting direction of the plug of the earth cord changes depending on the type of the vehicle, the front side, the rear side, and the like. Therefore, in order to cope with this change in the connection direction, for example, one terminal is joined to one side of one end side of the conductive plate, and one terminal is joined in a direction orthogonal to the previous terminal. Good.

The terminal may be bonded to the conductive plate with an adhesive, but the terminal and the conductive plate may be covered with plastic to bond them.
In this embodiment, the terminal 22 and the conductive plate 2 are made of plastic 25.
The terminal 22 and the conductive plate 21 were bonded to each other by covering 1 with each other. In this embodiment, since the terminal 22 and the conductive plate 21 are covered with hard plastic, the terminal 22 is deformed or damaged by the clamping force applied when fixing the connection device to the static elimination mat or the external force applied during use. In addition, the end of the conductive plate 21 will not be caught and injured during handling of the static elimination mat.
