Description

  The present invention relates to a wire sleeve for connecting two wires.

  Conventionally, an electric wire sleeve for electrically and mechanically connecting two electric wires has been provided. The electric wire sleeve includes a cylindrical sleeve body having both ends opened.

  In this type of wire sleeve, the conductor of one of the two wires is inserted into the opening at one end of both ends of the sleeve body. And the area | region where a conductor exists in the inside in one edge part of a sleeve main body is compressed, and an electric wire sleeve is compressed by the conductor of one electric wire. Furthermore, the conductor of the other electric wire is inserted into the opening at the other end of the sleeve body. And the area | region where a conductor exists in the inside in the other edge part of a sleeve main body is compressed, and an electric wire sleeve is compressed by the conductor of the other electric wire. In this way, the two electric wires are connected by the electric wire sleeve (see, for example, Patent Document 1).

  In general, the opening of the wire sleeve is formed to be substantially the same or slightly larger than the conductor of the wire. For this reason, when the conductor of the electric wire is inserted into the opening of the electric wire sleeve, unless the conductor is brought close to the opening accurately so that the central position of the electric conductor of the electric wire matches or substantially coincides with the central position of the opening of the electric wire sleeve, The tip of the conductor may be out of the opening of the wire sleeve and cannot be inserted into the opening.

  In particular, when connecting two electric wires by an indirect hot wire operation, an operator must remotely operate the positions of the conductors of the two electric wires. For this reason, the position of the conductor is likely to deviate from the position of the opening of the electric wire sleeve, and the tip of the conductor is easily detached from the opening.

  Thus, the operator must bring the conductor close to the opening of the wire sleeve so that the center position of the conductor of the wire does not deviate from the center position of the opening of the wire sleeve. It was difficult to insert into the opening of the wire sleeve.

  Next, the process of inserting the conductor 41 of the electric wire 4 into the electric wire sleeve 1 according to the embodiment will be described with reference to FIG.

  First, as shown to Fig.3 (a), the front-end | tip of the conductor 41 of the electric wire 4 is made to approach toward the guide surface 33 of the extension part 31 of one receiving part 3. As shown in FIG. As shown in FIG. 5B, after the tip of the conductor 41 is placed on the guide surface 33 of the extension portion 31, the tip of the conductor 41 is moved along the guide surface 33 of the extension portion 31 to the center C of the sleeve body 2. Slide toward the inside from the outside in the direction to approach the opening 22. Then, as shown in FIG. 4C, after the tip of the conductor 41 reaches the opening 22 of the hole 21, the tip of the conductor 41 is pushed into the hole 21 as it is, as shown in FIG. The conductor 41 of the electric wire 4 is easily inserted into the hole 21 of the sleeve body 2. In this manner, the conductor 41 of the other electric wire 4 can also be inserted into the other hole 21 of the sleeve body 2.

  Thus, since the receiving part 3 is extended from the edge part of the sleeve main body 2, the conductor 41 of the electric wire 4 can be mounted on the extending part 31 of the receiving part 3. FIG. As a result, if the electric wire 4 is moved in a state where the tip end portion of the conductor 41 is left in the receiving portion 3 and the tip end portion of the conductor 41 is along the receiving portion 3, the tip end portion of the conductor 41 becomes the receiving portion 3. Is guided into the sleeve body 2 through the opening 22 of the hole 21.

  In addition, the extending portion 31 of the receiving portion 3 has a gap between the radial end portions of the extending portion 31. Therefore, the extension part 31 is easy to put the conductor of an electric wire.

  Further, the extending portion 31 of the receiving portion 3 is formed along the circumferential direction of the conductor 41 of the electric wire 4. Therefore, the conductor 41 of the electric wire 4 is not easily displaced in the radial direction, and can be moved straight without moving up to the opening 22 of the hole 21. Therefore, the operator can easily move the conductor 41 of the electric wire 4 without dropping from the receiving portion 3 to the opening 22.

  Further, when the conductor 41 of the electric wire 4 is inserted into the hole portion 21 of the sleeve body 2, the extending portion 31 of the receiving portion 3 is arranged so as to cover the semicircular portion of the conductor 41, and the conductor 41 hardly protrudes in the radial direction. Therefore, when the conductor 41 of the electric wire 4 is inserted into the opening 22 of the hole portion 21 of the sleeve main body 2 and the outer peripheral portion of the electric wire 4 and the electric wire sleeve 1 is covered with an insulating tape or the like, the extending portion of the receiving portion 3 31 does not easily get in the way, and an insulating tape or the like is easily attached to the electric wire 4 and the electric wire sleeve 1.

  Further, the guide surface 33 of the extending portion 31 of the receiving portion 3 is continuous from the inner peripheral surface of the hole portion 21 of the sleeve main body 2, and no step is formed between the receiving portion 3 and the sleeve main body 2. Accordingly, when the tip end portion of the conductor 41 of the electric wire 4 is inserted into the opening of the sleeve body 2 from the guide surface 33 of the receiving portion 3, the tip end portion of the conductor 41 is not caught by the end portion of the sleeve body 2. Slide into the inner peripheral surface of the main body 2. Therefore, the operator can insert the conductor 41 from the guide surface 33 of the extending portion 31 of the receiving portion 3 into the opening of the hole portion 21 without receiving resistance.

  Further, the opening 22 of the hole 21 in the sleeve body 2 is larger than the inner diameter of the sleeve body 2. Therefore, the tip of the conductor 41 of the electric wire 4 can be easily inserted into the opening 22 of the hole 21 of the sleeve body 2.

  Moreover, since the receiving part 3 is provided in each of the both ends of the center C direction in the sleeve main body 2, either of the conductors 41 of the two electric wires 4 can be easily inserted into the hole 21 of the sleeve main body 2.

  Therefore, according to the electric wire sleeve 1 of this embodiment, there exists an outstanding effect that the conductor 41 of an electric wire can be inserted in the hole part 21 easily.
