Description

Detailed Description of the Invention

[0001]

[0001] The present invention is used as a heat medium for, for example, greenhouses, floor heaters, heater carpets, etc., or for melting snow buried in roads and roofs in heavy snowfall areas. The present invention relates to a connector for connecting a plurality of belt-shaped heating elements in a heating device.

[0002]

2. Description of the Related Art Generally, as a heating element used in this type of heating device, there is a band-shaped heating element having a large number of built-in heating elements. In this strip-shaped heating element, a heater element is covered with a synthetic resin insulating material, and a connecting wire extends at both ends or one end thereof. The plurality of strip-shaped heating elements are arranged at a predetermined interval and electrically and mechanically connected to each other to form a heating device.

[0003]

However, in order to arrange a large number of belt-shaped heating elements at regular intervals, a support sufficient to maintain the shape is provided, and an electric wire is attached to this support, and the electric wire is attached to the wire. The body wires must be connected individually. Therefore, there are problems that the structure becomes complicated, the operation is very troublesome, and the production cost is high.

Accordingly, the present invention provides a connector for a heating device which can connect a number of strip-shaped heating elements by simple means and securely and arrange the strip-shaped heating elements at regular intervals. The main purpose is to solve the conventional problem.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the connector for a heat generating device according to the present invention, a plurality of crimp terminals 2 having a U-shaped or cylindrical cross section are integrally formed at one side edge along the length direction at a predetermined interval. The two electrically conductive strip-shaped metal plates 1 and 1 are polymerized via the insulating plate 3 in a state in which the respective crimp terminals 2 and 2 are in close proximity to each other so as to form a pair, and the strip-shaped strips excluding the crimp terminals 2 ... The structure is such that the entire outer peripheral surfaces of the metal plates 1 and 1 are covered with a synthetic resin insulating coating 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on an embodiment shown in the drawings. In the figure, reference numeral A is a connector according to the present invention, and the connector includes two strip-shaped metal plates 1 and 1 formed of an electric conductor such as a copper plate. The strip-shaped metal plate 1 is integrally formed with a plurality of cylindrical crimp terminals 2 at one side edge thereof along the length direction at predetermined intervals.

The two strip-shaped metal plates 1 and 1 are polymerized via the insulating plate 3 in a state where the respective crimp terminals 2 and 2 are brought close to each other, and the crimp terminals 2 are removed. The entire outer peripheral surfaces of the strip-shaped metal plates 1, 1 are covered with a synthetic resin insulating coating 4. Therefore, one of the strip-shaped metal plates electrically becomes the positive side and the other strip-shaped metal plate electrically forms the negative side. The thickness of the strip-shaped metal plate 1 and the thickness of the synthetic resin insulating coating 3 covering the outer peripheral surface are set to such dimensions that the physical strength of the connector A can be maintained and its shape can be maintained while leaving appropriate flexibility. ing. The space L between the crimp terminals 2 and 2 forming the pair is formed to have the same size as the space between the connecting conductors 8 and 8 (see FIGS. 4 and 5) of the strip-shaped heating element B described later. Further, the length of the connector A and the number of the crimp terminals 2 are increased or decreased depending on the number of the strip-shaped heating elements B connected to the crimp terminals.

A strip-shaped heating element B connected to the crimp terminal 2
Are connected in parallel between two conductors 5 and 5 arranged in parallel, and the heater elements 6 and the conductors 5 and 5 are covered with a synthetic resin film 7. It is configured, and the conducting wires 8, 8 for connection are extended at one end thereof.

FIG. 5 shows an example of the use of the connector according to the present invention, in which the conductors 8, 8 of the strip-shaped heating element B are inserted into the crimp terminals 2, 2 which form a pair of the connector A and are suitable. The crimp terminal 2 is crimped and connected with a tool.
In the heating device thus constructed, the connector A having an appropriate strength holds the intermediate strip-shaped heating elements B at a predetermined interval, so that the heating device can be buried in a road or roof or kept warm. It is easy to work on the soil surface of the house or in a predetermined place.

Although the crimp terminal 2 of the connector A is formed in a tubular shape in the above embodiment, it may be formed in a U-shaped cross section as shown in FIG. 6 instead.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to only the structures of the embodiments, but includes the constituent elements thereof.
In addition, the present invention achieves the object of the present invention and can be appropriately modified and implemented within a range in which the following effects are obtained.

[0012]

As described above in detail, according to the present invention, the heating device can be composed simply by connecting the conductive wire of the linear heating element to the crimp terminal of the connector. It can be manufactured at low cost because it is composed of an extremely simple structure of an integral structure and a synthetic resin insulating film. Since it is possible to hold the apparatus at an interval, there is an excellent effect that construction such as burying on a road or a roof can be easily performed.
