Description

Sleeve for power line branch connection {BRANCH SLEEVE FOR POWER LINE}

The present invention relates to a branch sleeve used to connect and connect a main line (main line) and a branch line of a power line or a jumper wire which is not subject to tension, and more specifically, compresses by completely wrapping the main line and the branch line without any gaps when compressed by a compressor. As described above, the present invention relates to a power line branch connection sleeve that is stably connected and prevents inflow of moisture or foreign substances, thereby preventing corrosion.

In general, the main line and branch line connection and connection part of the power line constituting the transmission and distribution line for power supply cause corrosion and heat when water or foreign matter such as rainwater or dew enters, resulting in power failure due to disconnection of the connection part. Of course, there is a safety problem that the risk of electric shock accidents are several times higher than usual.

Accordingly, the main line and the branch line of the aluminum power line are connected and connected by using a so-called branch sleeve to prevent the inflow of moisture, foreign matters, etc., thereby preventing corrosion.

For example, a branch sleeve for connecting a distribution line is disclosed in Korean Utility Model No. 20-0470445. As shown in FIGS. 1 and 2, the main body 100 includes a first connection portion 101 for connecting the main line 110 and a second connection portion 102 for connecting the branch line 120.

However, the branch sleeve 1 is inserted into the main line 110 and the branch line 120 in a state in which the coating is removed in the first connecting portion 101 and the second connecting portion 102, and then the first connecting portion in the process of compressing with a compressor. A gap is formed in a portion where the edge end portions of the 101 and the second connection portion 102 come into contact with each other as they collide with the corresponding portions of the main body 100, and a foreign material or corrosion such as rainwater, metallic dust, etc. is formed through the gap. The material is permeated to cause corrosion and poor connection, and as a result, the connection part is melted due to an increase in electrical resistance and a rise in temperature, thereby causing disconnection and power failure of the main line 110 and the branch line 120.

In order to solve the problems of the prior art, the Republic of Korea Patent No. 10-1514785 discloses a branch sleeve for power line connection researched and developed by the present inventors.

Outer protrusions 15 and 25 having lengths are formed, respectively, and inner protrusions 16 and 26 having a shorter length than the outer protrusions 15 and 25 at inner edges of the fastening grooves 13 and 23. Are formed respectively.

Therefore, when compressed by a compressor, the other ends 12 and 22 are inserted into the fastening grooves 13 and 23 along the inner surface of the outer protrusions 15 and 25, and the outer protrusions 15 and 25. ) May be deformed while pressing the other ends 12 and 22 toward the inner protrusions 16 and 26 to prevent a gap from being formed in contact with the main line 200 and the branch line 300 of the power line.

However, this is because of the mechanical properties made of aluminum material, the main line inserting groove 10 and the branch line inserting groove 20 are inserted into the main line 200 and the branch line 300, respectively, the main line inserting groove 10 in the process of compressing with a separate compressor And the inner part of the branch line insertion groove 20 is deformed like a dent, which causes poor compression in the base portion between the main line insertion groove 10 and the branch line insertion groove 20, Moisture or foreign matter such as rain water or dew, or the corrosive substance permeates through the main line 200 and the branch line 300 has a problem of causing corrosion and increased resistance.

In addition, due to the length and shape of the outer protrusions 15 and 25 and the inner protrusions 16 and 26, expensive aluminum metal materials enter a lot and have a high defect rate.

Here, the background art or the prior art as described above is merely useful for understanding the technical significance of the present invention as information possessed by the present inventors or acquired in the process of deriving the present invention, and the technical field to which the present invention belongs before the application of the present invention.
