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 belt-like heating elements are arranged at predetermined intervals and electrically and mechanically connected 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 heating device according to the present invention, a plurality of U-shaped or cylindrical cross sections are provided at predetermined intervals on one side edge along the length direction of the long conductive strip-shaped metal plate 1. The crimp terminals 2 are integrally formed so as to protrude, and the entire peripheral surface of the strip-shaped metal plate 1 except for the crimp terminals 2 is covered with a synthetic resin insulating film 3.

[0006]

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 drawings, reference symbol A denotes a connector according to the present invention, which includes a strip-shaped metal plate 1 formed of a conductor such as a copper plate. This strip-shaped metal plate 1
A plurality of cylindrical crimp terminals 2 are integrally formed at one side edge along the length direction at predetermined intervals to protrude.
The entire peripheral surface of the strip-shaped metal plate 1 except for the crimp terminals 2... Is covered with a synthetic resin insulating film 3. In addition, the thickness of the strip-shaped metal plate 1 and the insulating coating 3 made of synthetic resin which
Is set to a dimension that can maintain the physical strength of the connector A and maintain its shape while maintaining appropriate flexibility. In addition, the length of the connector A and the crimp terminal 2
Is increased or decreased depending on the number of the belt-shaped heating elements B connected to the crimp terminal 2.

The belt-shaped heating element B connected to the crimp terminal 2 is
A large number of heater elements 5 are connected between the two left and right conductors 4, 4 arranged in parallel, and the periphery thereof is a synthetic resin film 6.
, And connecting wires 7, 7 extend from both ends thereof.

FIG. 5 shows an example of the use of the connector according to the present invention. Two connectors A, A are arranged on the left and right sides, and a lead wire 7 of a band-shaped heating element B is attached to each crimp terminal 2. 7 is inserted, and the crimp terminal 2 is crimped with an appropriate tool and connected. The heating device thus composed is embedded in a road or a roof because the intermediate belt-shaped heating elements B are held at predetermined intervals by the left and right connectors A, A having appropriate strength. It is easy to install them on the soil surface of a heat insulating house or at a predetermined location.

In the above embodiment, the crimp terminal 2 of the connector A is formed in a cylindrical shape. Alternatively, the crimp terminal 2 may be formed in a U-shaped cross section as shown in FIG.

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.

[0011]

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.
