[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention incorporates an electric heating element such as a surface heater attached to a floor base such as a concrete slab, a throw-on plywood or a plywood laminated on a joist for floor heating. The present invention relates to a floor heating panel and its electrical connection structure.

[0002]

2. Description of the Related Art As one of the floor heating panels of this type, conventionally, floor heating as shown in FIG. 6 has been performed in order to facilitate electrical connection between floor heating panels to improve efficiency in construction. Panel 50 has been proposed (Actual Kaihei 2-1036).
(See also No. 07, etc.). The floor heating panel 50 of the illustrated example is
Briefly, the surface layer member 51 including the decorative material 52 and the surface layer base plate 53, the surface heater (or line heater) 55 that constitutes an electric heating element, and the back layer member 57, both sides of the laminated body. In addition, a concave conductive connector 60 and a convex conductive connector 70 are provided to electrically connect the floor heating panels 50 to each other.

The concave conductive connector 60 includes a base 61 made of synthetic resin having a recess 66 having an open front surface, and two substantially U-shaped contact fittings 62 fixed in the base 61.
And 62. In addition, the convex conductive connector 70 is
A base 71 made of a synthetic resin fitted in the recess 66 of the concave conductive connector 60 and two rod-shaped or plate-shaped contact metal fittings 72 inserted into the contact fittings 62, 62 of the concave conductive connector 60 and brought into contact with each other; It consists of 72. The concave conductive connector 60 (the contact fitting 62 thereof) and the convex conductive connector 70 (the contact fitting 72 thereof) are connected by a lead wire 64, a wiring cord 65 such as a cabtire cord, and the surface heater 55 and the The wiring cord 65 is connected via a lead wire and an electrode which are not shown.

Such a floor heating panel 50 is usually one shank.
It has a 6-inch rectangular shape, and the required number of sheets are laid side by side on the floor foundation surface to form a so-called floor surface flooring. Floor heating panel 50 located above
By fitting the convex conductive connector 70 of the rear floor heating panel 50 to the concave conductive connector 60 of FIG. To be electrically connected.

[0005]

However, the concave conductive connector 60 and the convex conductive connector 70 as described above are used.
The floor heating panel 50 provided with the above has the following problems. (1) That is, as shown in FIG. 7, floor heating panels 50, 50, ... Are laid side by side in a certain area, and for example, the X-zone and the Y-zone are sectioned at the boundary S (only the X zone is heated , So that the three modes of heating only the Y zone and heating both the X and Y zones can be selected), it is necessary to separate the power supply system for the X zone and the Y zone. The floor heating panels 50 are electrically connected to each other by fitting the concave conductive connector 60 and the convex conductive connector 70 (the fitting portion is indicated by C in FIG. 7).
However, since the electrical connection between the floor heating panels 50 is completed at the same time as the floor construction (laying of the floor heating panel 50), the power supply system cannot be divided and the chamfering is impossible.

(2) As shown in FIG. 8, at least a convex conductive connector 70 is installed adjacent to a floor heating panel 50 'provided so as to project outward, and an electric heating member (heater) and a conductive connector are incorporated therein. When arranging the border panel 80 which is not provided, it is necessary to make a hole 82 for accommodating the convex conductive connector 70 in the border panel 80.
Further, since the contact metal fitting 72 of the convex conductive connector 70 is exposed to the outside, an electrical insulation treatment or the like is required for safety measures, and the construction work is troublesome.

(3) After construction of the floor heating panel 50, it is necessary to supply power to each laid floor heating panel 50. At the time of this power supply, power supply connection as illustrated in FIG. 4 described later is performed. Container, ie, concave conductive connector 60
Connector 40 that can be fitted and connected to the convex conductive connector 7
Two types of connectors, that is, a connector (not shown) that can be fitted and connected to 0 are required. Therefore, it is necessary to prepare two types of connectors in advance, which is disadvantageous in terms of cost, and the connector for power supply cannot be shipped unless it is decided which connector will be used at the construction site. Is likely to occur and management becomes troublesome.

In view of such a point, the present invention has the above-mentioned (1).
To eliminate the problem of (3), specifically, it is possible to carry out chamfering as needed, and it is not necessary to perform troublesome work such as insulation treatment at the time of construction, and power supply is possible. It is an object of the present invention to provide a floor heating panel and an electrical connection structure for the floor heating panel, in which only one type of connector for use is prepared.

[0009]

In order to achieve the above-mentioned object, a floor heating panel according to the present invention is provided with a layered body composed of a surface layer member, an electric heating element, and a back layer member. In order to provide a physical connection, a required number of recessed conductive connectors having the same size and shape are internally provided in such a manner that the whole thereof is located inside the peripheral surface of the laminate.

In the floor heating panel of the present invention, a preferred embodiment of the concave conductive connector is one in which a waterproof sheet is provided to cover the front opening. Further, the electrical connection structure of the floor heating panel according to the present invention, the floor heating panel of the above-mentioned configuration, is installed side by side on the floor foundation surface with the concave conductive connectors facing each other, the said facing. A relay joiner is inserted between a pair of concave conductive connectors that are provided to make them conductive.

In a preferred embodiment of this case, the concave conductive connector includes a base body having a recessed front surface and at least two substantially U-shaped contact fittings fixed in the base body. And the relay joiner is composed of an insulating support and at least two rod-shaped or plate-shaped contact fittings penetrating so as to project in the front and rear thereof, and the pair of concave shapes opposed to each other. An example is one in which both ends of the contact metal fittings of the relay joiner are inserted and brought into contact with the contact metal fittings of the conductive connector.

[0012]

[Operation] When the floor heating panel according to the present invention configured as described above is constructed, for example, a relay joiner is attached to the concave conductive connector of the floor heating panel arranged on the floor foundation surface first. I'll do it. In this case, in a preferred embodiment, the relay joiner has its front half fitted to the concave conductive connector and its rear half projected laterally from its floor heating panel. Then, the rear floor heating panel is juxtaposed with the front floor heating panel so that the concave conductive connector of the rear floor heating panel is fitted to the rear half of the protruding relay joiner. As a result, the floor heating panels are juxtaposed on the floor foundation surface with the concave conductive connectors facing each other, and a relay joiner is provided between the pair of concave conductive connectors facing each other. After being inserted, the two connectors are electrically connected by the relay joiner, and the two panels are electrically connected.

Here, when a predetermined number of floor heating panels are laid in a certain area and the chamfering (see FIG. 2 described above) is performed at a specific position in the area, the chamfering is located at the boundary of the chamfering. No relay joiner is inserted between the concave conductive connectors of the adjacent floor heating panels, and they are not electrically connected.
In this way, the adjacent panels located at the boundary of the chamfer are electrically separated from each other, and the power supply system is divided at the boundary, which enables the chamfering.

In the floor heating panel of the present invention, the required number of concave conductive connectors having the same size and shape are internally provided in such a state that the whole is located inside the peripheral surface of the laminate. There is no protrusion to the outside, so there is no need to make holes in the border panel, and the contact metal fittings of the concave conductive connector are not exposed to the outside (in the recess), so there is no need for electrical insulation treatment. , Construction work is easy.

In particular, by covering the front opening of the concave portion of the base of the concave conductive connector with a waterproof sheet, it is possible to prevent the ingress of moisture and dust into the connector, and to obtain waterproof and dustproof effects. Since the waterproof sheet can be easily broken when the relay joiner is inserted into the concave conductive connector, it does not disturb the connection. Furthermore, when supplying power, it is only necessary to prepare one type of power supply connector, that is, a connector that can be fitted and connected to the concave conductive connector, so that the power supply direction at the construction site (concave and convex Which connector is to be used) does not need to be taken into consideration, and there is no problem in shipping and management.
