Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coupling device for bendably mechanically and electrically coupling the ends of electric heating mats such as hot carpets.

When connecting a plurality of electric heating mats such as hot carpets mechanically and electrically, it is easy to connect the end faces with electrodes made of pins and jacks.

When hot carpets, etc. are joined together in this way, the pins are inserted between the end faces of the hot carpets, so it is impossible to fold them as they are, and there is the hassle of having to remove the electrodes each time. However, the pin is also easy to come out of the jack, and improvements in this respect are desired.

In view of the above points, the present invention provides a connecting device for hot carpets, etc., which mechanically and electrically connects the ends of hot carpets, etc. so that they can be bent, and which can be folded while being connected. With the goal.

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

A step recess 2 is provided on one surface of the edge where the ends of the hot carpets 1 and 1 are joined, and a female electrode 4 is provided on the step surface 3 on the end side of the hot carpets 1 and 1 that forms this step recess 2 (FIG. 2). .

As shown in FIG. 1, the connector 5 has locking blocks 8, 8 integrally provided at both ends of one surface of a plate 7 having a hinge portion 6 in the middle.
Male side electrodes 9, 9 for electrical connection are provided on opposing surfaces of the connector, and the electrodes 9, 9 on both sides are electrically connected by a flexible wire passing through the hinge portion 6, a copper foil 10, or the like.

As shown in FIGS. 2 and 3, the plate pieces 7 of this connector 5 are placed back to back from the hinge part 6,
The connector 5 with the plate pieces 7 placed back to back is fitted into the step recesses 2, 2 of the hot carpets 1, 1 with their end surfaces aligned and the step recesses 2, 2 sides facing each other. 1, the male side electrodes 9, 9 of the connector 5 were inserted into the female side electrodes 4, 4 on the step surfaces 3, 3 of the step recesses 2, 2, and the connectors were placed back to back. By opening the ends of the hot carpets 1, 1 around the hinge part 6 of the connector 5, the hot carpets 1, 1 are mechanically and electrically connected, and can be laid on the floor (the fourth figure).

To separate the hot carpets 1, 1, lift the connection between the hot carpets 1, 1 and return the connector 5 to the inside, and the electrodes 9, 9 of the connector 5 and the electrodes 4,
4 are removed, and the connector 5 can be easily removed from the stepped recesses 2, 2 of the hot carpet 1, 1.

As described above, the present invention can provide a coupling device for electric heating mats that has a simple structure, is easy to attach and detach, and does not apply excessive force to the electrical connection portions. Furthermore, with this configuration, when the electric heating mats are laid on the floor, the connector restricts the individual movement of the electric heating mats, so that mechanical connection is also possible.
