Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention directly contacts the stripped insulation part of a foil or sheet-shaped conductor, which has a sandwich-shaped insulation coating of synthetic resin sheet material, with the stripped insulation part of the cable wire. The present invention relates to a connector used for electrically connecting the bare electric wire portion and the insulation-peeling portion in the brought state.

[0002]

[Prior Art]

 The above-mentioned sheet-shaped conductors are mainly used for floor heating, concrete surface heating, etc., but they are not yet in widespread use as general products. There is no suitable means for energizing the conductor and the bare wire. Thus, the conventional means for energizing the sheet-shaped conductor and the bare wire is to solder the bare wire part of the cable wire directly to the stripped part of the sheet-shaped conductor, or to separate the stripped part of the sheet-shaped conductor. Put the bare wire part of the cable wire on the upper part of the cable, put two metal plates on the upper and lower sides, and crimp rivets into the holes that are pre-formed at both sides of the bare wire part of these metal plates. By inserting and inserting and caulking and connecting by using a caulking tool, the bare wire portion and the insulation peeling portion are electrically connected.

[0003]

[Problems to be solved by the device]

 Therefore, in the case of the conventional means of this type, in the former case, the soldering work is very complicated and requires skill and time, and the connection state and the bonding force are unstable, and in the latter case. In this case, the bare wire portion of the cable wire is applied between the metal plate and the sheet-shaped conductor to maintain this state, and rivets are inserted into the rivet holes of the sheet-shaped conductor and the upper and lower metal plates to tighten them. There was a problem that workability was difficult because it required a very troublesome procedure of crimping with tools, and the total cost was high.

In view of this, the present invention solves the problems of such conventional connectors, and uses a metal plate material that can be plastically deformed without using a troublesome connecting means such as a solder or a rivet. However, the main object of the present invention is to provide a connector capable of electrically connecting the sheet-shaped conductor and the bare electric wire portion of the covered electric wire easily and reliably.

The sheet material (B) is provided with connecting portions (3) having narrow widths at both end portions and slightly protruding. Reference numeral (A) is a connector according to the present invention, which is made of a plastically deformable conductive metal plate material such as a copper plate, and the left and right edges of the horizontal board (11) are substantially half-shaped. It is folded back in the shape of a letter, and for inserting the connection part (3) with a narrow width of the sheet material (B) between the folding pieces (12), (12) and the horizontal substrate (11). A space (15) is formed. Further, the folded-back pieces (12), (12) are integrally formed with downward projections (13), (13) having sharp tips. Also, a pair of left and right crimping pieces (14), (14), which are substantially U-shaped, for holding and holding the bare electric wire portion (k) of the cable electric wire (K) on either of the front and rear end portions of the plate material (11) Are integrally connected.
