The present invention relates to a sleeve for connecting overhead wires, and more particularly, a sleeve for wire connection of overhead wires that can not only facilitate the coupling of jumper wires or branch wires connected to the main wire, but also reduce parts. It is about.

Electric wires are used as a means for supplying electric power for each consumer to the power obtained from the power plant, which are wired in the ground or suspended on the ground by telephone poles.

In this wiring method, the overhead wire is installed by fixing the wire to a support made of an insulator such as insulator on the support object. One example of the facility of such a overhead wire is shown in FIGS. 1 and 2.

As shown in the figure, the support is installed vertically with the pole at the top of the pole, and a plurality of insulators are installed on the support, and the end of the main line 300 is insulated from the insulator, and the main line 300 is not stretched. It is not supported, and the tension between the two main lines (300) means (not shown) is installed to be able to adjust the tension between the two main lines connected to each other.

That is, the main line 300 is divided and divided around the electric pole, and is in an electrically disconnected state, the ends of each main line 300 are coupled to each other by the insulator and the tension control means, to electrically conduct the two main lines The jumper wire 310 is provided by means.

Of course, the branch line (not shown) may be connected to connect the wire from the main line 300 to the customer.

The main wire 300 constituting the overhead wire is configured as an aluminum wire, the jumper wire is composed by connecting the copper wire 312 and the aluminum wire 311, to connect these wires (300, 311, 312) Branch sleeve 100 and the foreign metal sleeve 200 is provided as a means for.

As shown in FIG. 2, the branch sleeve 100 as the wire connecting means connects the main wire and the aluminum wire, and the heterogeneous metal sleeve 200 serves to connect the aluminum wire and the copper wire.

That is, the heterogeneous metal sleeve is a means for connecting the copper wire and the aluminum wire having different properties constituting the jumper wire, and a copper pipe is installed inside the portion where the copper wire is connected to increase the electrical connection ratio between the sleeve and the copper wire. .

However, as described above, since the conventional overhead wires have to use two sleeves to connect the jumper wires, the material cost is high, and a lot of work time is required in performing the work of crimping the two sleeves to connect the wires. There was a downside to this.

The present invention has been developed to solve the problems of the prior art as described above, by integrally forming a sleeve connecting the branch line or jumper wire to the main line to reduce the material cost by enabling the connection of the electric wire or branch line with a single sleeve It is also an object of the present invention to provide a composite sleeve for connecting dissimilar metal wires in overhead wires, which can reduce working time.

The present invention is a sleeve for electrically connecting between the main lines of the overhead wire is suspended in the air by the pole, the main line connection portion is cut one side wall is inserted so that one end of the main line passes through; The present invention relates to a composite sleeve for wire connection of a process wire composed of a branch wire connection part in which holes are formed such that a jumper wire or a branch wire is inserted in the longitudinal direction on the other side of the main wire connection part.

The present invention can connect the main line and the jumper line or branch line to one composite sleeve can reduce the material cost.

In addition, by pressing only one sleeve to connect between the wires there is an effect that can reduce the time required for wiring work.

In addition, the copper wire is integrally formed on one inner side of the composite sleeve, so that two wires made of dissimilar metals can be easily connected.

Hereinafter, with reference to the accompanying drawings the composite sleeve for the connection of the overhead wire according to the present invention will be described in detail. In the following description, the "different metal" wire connection will be mainly described, but it will be obvious that the composite sleeve according to the present invention can be equally used not only for "different metal" but also for "homogeneous metal" wire connection.

Figure 3 is a perspective view showing a composite sleeve for dissimilar metal wire connection according to the invention, Figure 4 is a perspective view of the connection portion connected by a composite sleeve for dissimilar metal wire connection according to the invention, Figure 5 6 and 7 are perspective views showing an example of a processed wire connected by using a composite sleeve for connecting dissimilar metal wires according to the present invention.

The composite sleeve for heterogeneous metal wire connection of overhead wire according to the present invention is characterized in that it is possible to connect two wires composed of dissimilar metal with one sleeve. A sleeve for electrically connecting between main lines of overhead wires suspended in the air by electric poles, comprising: a main line connection part 11 having one side wall cut out to be inserted through one end of the main wire 300; On the other side of the main line connection portion 11 is composed of a branch line connection portion 12 having a hole formed so that the jumper wire or branch line 320 is inserted in the longitudinal direction.

That is, as shown in Figure 3, the composite sleeve for connecting the heterogeneous metal wire of the processed wire of the present invention is formed with a main line connection portion 11 through which the main line 300 is inserted and coupled to one side, the main line connection portion On the other side of (11), the branch line connection part 12 is formed. Although the main connection part 11 and the branch connection part 12 are shown in parallel in the drawing, the relative direction or distance of both connection parts may be appropriately selected according to the environment used.

As shown in FIG. 3, the main line connection part 11 has one side wall cut in the longitudinal direction of the hole (that is, the cross section is hooked) so that the main line 300 is inserted into the main line connection part 11 through this portion. It was.

That is, as described above, the main line 300 is a state in which the ends thereof are already connected to the tension control means or insulator, and thus the main line 300 connects the composite sleeve 10 to the main line 300 connected to the tension control means or the insulator. In order to install, one side of the main connection part 11 should be opened.

If one side of the main line connection part 11 is not opened, the main line connection part 11 may be formed from the end of the main line connection part 11 of the composite sleeve 10 before fixing the end of the main line 300 to the tension adjusting means or the insulator. After installing the composite sleeve 10 to the main line by inserting the main line 300, the main line 300 should be fixed to the tension control means or insulator, and in this case, the composite sleeve 10 of the main line 300 If it is pushed to the middle, it is difficult to pull it to the end, thereby reducing workability.

In addition, when electrically connecting the two main lines (300) already installed, that is, to replace only the jumper wire or branch line (hereinafter referred to as the branch line) to the main line 300 by opening one side of the main line connection portion 11 as described above. The composite sleeve 10 can be easily installed.

As shown in FIG. 4 by inserting the main line 300 through the open portion of the main line connection portion 11 with one side open as described above, by pressing the side wall of the main line connection portion 11 using a pressing means. As the connection part 11 is distorted, the inner wall of the main connection part 11 is in close contact with the main line 300, and the composite sleeve 10 is installed at the main line 300.

As shown in the drawing, the branch line connection part 12 may be formed in the form of a long circular hole or a through hole.

6 and 7, since the branch line 320 is short and the portion connected to the sleeve 10 is at its end, the branch line 320 is pushed in from the end of the branch line connection part 12 so that the wire is connected to the branch line part 12. Since it can be fitted into the branch connection line 12 is to be formed in the form of a circular hole.

On the other hand, when forming a branch line or a jumper wire with wires made of the same metal as the main line 300, the composite sleeve 10 of the present invention can be made of the same material as the main line 300, and the main line 300 and If jumper wires or branch wires are used as other metals, the foreign metals shall be electrically connected. Therefore, unlike the main wire 300 which is an aluminum wire, when the branch wire or the jumper wire is the copper wire, it is preferable to apply a sleeve in which a separate copper pipe 12a is inserted-coupled to the hole of the branch wire connection portion 12. As a result, the electrical connection between the sleeve and the branch line can be made smoothly.

In the above, the use of the composite sleeve according to the present invention has been described taking the case of connecting the overhead wire and the jumper wire or the branch wire, but the composite sleeve according to the present invention may be used for any purpose for combining heterogeneous wire or homogeneous wire. Of course it will be available. For example, it may be used for connecting overhead wires and transformers, connecting overhead wires and G / S, and branching overhead wires.
