〈産業上の利用分野〉
本考案は被覆電線を直列的に接続するために用

た。<Prior Art> Conventionally, a wide variety of sleeves for connecting electric wires of this type have already been commercialized. However, in these products, the resin coating containing the metal sleeve for wire connection caulking is usually made of polyvinyl chloride, and the degree of heat shrinkage is poor.

きないという欠点があつた。<Problem to be solved by the invention> Therefore, in the conventional sleeve for connecting electric wires, a gap is created between the large diameter part into which the sheathing part of the electric wire to be connected is inserted and the sheathing part of the electric wire, and the sheathing is peeled off. The disadvantage was that it was not possible to maintain the watertightness of the connections made with bare electric wires, and that they could not be used in humid locations with a lot of water droplets due to the risk of electrical leakage.

提案するものである。 The purpose of the present invention is to solve this problem, and although the sheathing part of the connecting wire is formed to have a large diameter part that can be easily inserted when connecting the wires, it is difficult to avoid this large diameter part after the wires are connected. It is possible to reduce and deform the structure so that the diameter part is in close contact with the wire sheathing, and to make a watertight contact, and furthermore, the watertightness will not be destroyed even if the metal sleeve is roughly crimped and deformed with a crimping tool. We propose a sleeve for connecting electric wires.

This embodiment relates to a metal sleeve 1 for connecting and caulking electric wires, in which the central part of the cylinder has a small diameter 1a for a stopper, and both left and right ends have tubes for inserting bare electric wires. The metal sleeve 1 is made of copper, the outer sheathing sleeve 4 that encases it is made of polyvinyl chloride, and the outer heat-shrinkable tube 2 is made of lightly colored transparent nylon, and its entire inner surface is coated with polyamide. It is made into a double tube in which a hot melt layer 3 of material is formed. The covering sleeve 4 is formed into a cylindrical shape with the same diameter over the entire length, and the copper sleeve 1 is housed in the middle part thereof, and the double tube 2 is heated and shrunk only in its central part to become a small diameter part 2a. As shown in FIG. 1, it has a structure in which it is closely attached to the outer peripheral surface of the covering sleeve 4. By doing so, the unshrinked large diameter portions 2b, 2b of the heat-shrinkable tube 2 are formed on the outer side of both ends of the covering sleeve 4.

て使用することができる。<Effects of the invention> As is already clear from the above explanation, the invention has the following effects:
In a sleeve for connecting electric wires, the outer periphery of the part where the metal sleeve is deformed by pressure is covered with a heat-resistant covering sleeve and a covering tube, and the outer covering tube is made of a heat-shrinkable resin material to cover both ends of the covering sleeve. Since it is formed so as to protrude outward, the outer periphery where the pressure connection of the wire is deformed by pressure with the pressure tool is doubly protected by the covering sleeve and the covering tube, so that it cannot be violently deformed by the pressure tool. It is safe because it does not break even when pressurized, there is no risk of electrical leakage, and the heat-shrinkable tube can be made into a thin film that does not inhibit the flexibility of the wire. Since it can be easily attached to the electric wire and the watertightness of the electric wire connection part can be maintained reliably, it has the advantage that it can be used as a connection sleeve without the risk of electric leakage even in humid areas. In particular, since an adhesive layer is formed on the inner surface of the sheathing tube using a heat-melting resin or adhesive, there is no risk of water droplets entering the connection sleeve from the wire sheathing, making it a safe wire connection. Can be used as a sleeve.
