[0003]

[Problems to be solved by the device]

 However, when the branch sleeve is used to branch and connect an electric wire from the main voltage line to the branch line, it is necessary to insert the connecting pin of the fixing piece into the connecting hole formed separately for each sleeve and bend it. Not only was the time and labor required for the work to be carried out at the time of its implementation, but the sleeve body and fixing piece were not suitable for mass production.

The present invention makes use of the advantages of the branching sleeve of the prior application mentioned above, and also eliminates the drawbacks thereof, so that not only can the branching wire be reliably and quickly connected, but also mass production is possible. It is an object of the present invention to provide a branch sleeve for connecting a low voltage electric wire, which can reduce the cost.

[0005]

Means for Solving the Problems The technical means of the present invention for achieving the above object is to form a sleeve body and a fixing piece separately from each other and to connect them to each other to connect them to each other. In this case, a retaining strip having a vertical groove is formed on the inside of the bottom surface of the sleeve body in a protruding manner, and an upper narrow narrow wide projection is provided at the lower portion of the fixing piece, and the vertical groove of the retaining strip is By inserting the protrusions of the fixing piece, a space for inserting the main voltage line and a space for inserting the connecting electric wire are separately formed on the left and right sides inside the sleeve body, and the bare wire portion of the electric wire is inserted into each space and the sleeve is inserted. By squeezing from the left and right sides of the main body, the sleeve main body and the fixing piece are firmly connected to each other so that both electric wires can be connected.

[0006]

[Action]

 According to the above technical means, the main voltage line and the bare wire portion of the connecting electric wire are inserted into the space portions on both sides of each section formed by the fixing piece mounted inside the sleeve body. By pressing the sleeve body from the left and right sides, the wires on both sides can be connected accurately. If the wires have different thicknesses, the space for inserting the left and right wires can be easily adjusted to the thickness of each wire by simply replacing the prepared fixing pieces with different shapes. No matter what, you can perform a wide range of wire connection work. When manufacturing, a conductive material such as electrolytic copper can be continuously molded by an extrusion method using a die and then cut into a certain length, which makes manufacturing very easy and speedy, and it can be mass-produced to a certain standard. It is possible to produce.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments of the accompanying drawings. As shown in FIGS. 1 to 3, the sleeve body 1 made of a conductive material is curved so that both side portions of the bottom surface project outward in a semicircular shape in a lateral cross section, and the sleeve body 1 is formed on the inner side of the bottom surface along the axial direction. A hook 4 having a vertical groove 3 is formed so as to project. The fixing piece 2 which is formed separately from the sleeve body 1 and is used in combination with the sleeve body 1 has an upper narrow lower wide projection 5 at the lower part thereof.

Then, the protrusion 5 of the fixing piece 2 may be inserted into the vertical groove 3 of the hook 4 of the sleeve body 1 to form a main voltage line insertion space and a connecting wire insertion space separately on the left and right. If the main voltage wire 6 and the bare wire portion of the connecting wire 7 are inserted into each section and squeezed from both the left and right outside of the sleeve body 1, the sleeve body 1 and the bare wire portion fixing piece 2 are deformed and the sleeve body The fixing piece 2 is easily and firmly connected to the first wire 1, and both electric wires are connected.

The branch sleeve having such a structure does not have, for example, the structure of the pin or the structure of the coupling hole in the above-mentioned prior application, and therefore, a semi-solid solution of electrolytic copper is continuously molded by a die extrusion method at the time of production. Since the production is almost completed if cut into a certain length, the production is very easy and quick, mass production of a certain standard is possible, and the manufacturing cost can be greatly reduced.

In order to carry out the work of branching the electric wire with such a branch sleeve, first, as shown in FIGS. 2 (A) and 3 (A), the main groove is mainly formed in the vertical groove 3 of the hook 4 of the sleeve body 1. The ridge 5 of the fixing piece 2 that is suitable for the voltage 6 and the thickness of the connecting wire 7 is inserted and connected. Next, the bare wire portion of the main voltage wire 6 with the coating removed is inserted into one of the space portions on both sides divided by the fixing piece 2, and the distal end portion of the connection electric wire 7 with the coating removed is inserted into the other space portion. To insert. After that, if the sleeve body 1 is squeezed from both sides by a squeezing machine, the electric wires 6 and 7 on both sides can be squeezed firmly and easily connected as shown in FIGS. 2 (B) and 4. At this time, the latching ridge 4 provided with the vertical groove 3 receives a compressive force from the left and right, bends inwardly, and strongly clamps the upper narrow narrow lower wide ridge 5 inserted therein, The sleeve body 1 and the fixing piece 2 do not have to be separated from each other in the vertical direction and can be firmly connected to connect the electric wires 6 and 7 on both sides. As described above, it is not necessary to insert a separate pin and bend each pin as in the previous application, so that a complete branching and connecting work of electric wires can be easily performed.

As another embodiment of the present invention, as shown in FIG. 3 (B), the lower protruding portion 5 of the fixed piece 2 is configured so that the position thereof is deviated to one side deviated from the center, and the left and right spaces are arranged. If the size is different, it is possible to easily and easily connect the thick main voltage wire 6 and the small-diameter connecting electric wire 7. Depending on the thickness of the wire, etc., if only the fixing piece 2 is replaced with a standard in which the position of the ridge 5 is different, it can be easily applied and used regardless of the standard and thickness of the wire.

[0012]

[Effect of device]

 As described above, according to the branch sleeve of the present invention, it is possible to easily and surely connect by simply stripping 5 to 10 cm of the coating of the electrical wire, which was conventionally stripped by 40 cm or more at the time of branching the electrical wire. By preventing waste of electric wires and preventing accidents such as power outages due to complete connection, uninterruptible power transmission is possible and the work is extremely simple, so labor productivity can be significantly improved. In addition, since it is possible to prevent overvoltage transmission, it is possible to prevent accidents with respect to household appliances of consumers, and prevent substituting payments due to their damage, thus preventing economic loss. In addition, maintenance costs can be significantly reduced by reducing the number of personnel required for repairs and repairs. Further, as described above, not only the branch connection work of the electric wire becomes very easy, but also large-scale production becomes possible, so that it can be offered at a cost.
