Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression branch sleeve used for connecting a high-voltage main wire and a switch lead wire, connecting two main wires with each other by edging or T-branching.

[0002]

2. Description of the Related Art When connecting a high voltage main line B laid over a utility pole A as shown in FIG. 7 and a lead wire D of a switch C attached to the utility pole A, as shown in FIG. The compression branch sleeve F has been used when connecting the high voltage main lines B that are laid orthogonally to each other by the branch line E, or when connecting the high voltage main lines B that are laid on the utility pole by the edging line.

As shown in FIG. 6, a conventional compression branch sleeve F includes a main line sandwiching portion H in which a fitting opening G for covering a stripped main line conductor of an imaginary main line is formed, and a branch line. A branch line holding portion J having an insertion hole I into which the stripped branch line conductor can be inserted is integrally formed of a metal material such as aluminum.

In order to connect the high voltage main line B and the lead wire D of the switch C with the compression branch sleeve F as shown in FIG. 7, the lead wire D is conventionally stripped to expose the conductor to the outside. High pressure main line B
The main line conductor exposed to the outside by peeling off the coating of No. 2 was compressed and held by the main line clamping portion H of the compression branch sleeve F, and the high voltage main line and the switch lead wire D were electrically connected.

In order to connect the high voltage main lines B to each other by the compression branch sleeve F as shown in FIG. 8, the coating of each of the two high voltage main lines B to be connected is peeled off and exposed to the outside. The main line conductors are compressed and held by the main line holding portions H of the respective compression branch sleeves F, and the branch line conductors that are stripped off and exposed to the outside are inserted into the branch line holding portions J and held in compression. Thus, the two high voltage main lines B were electrically connected to each other.

As described above, the connection work is completed by covering the outer circumference of the branch connection portion using the compression branch sleeve F with a cover (not shown) and waterproofing and dustproofing it.

[0007]

When crimping and holding the main wire conductor suspended in the main wire holding portion H of the compression branch sleeve F in the above connecting work, the main wire conductor is opened in a C-shape as shown in FIG. The fitting opening G of the main line sandwiching portion H is pressed against the imaginary main line conductor K, and in this state, the main line sandwiching portion H is compressed by a compression tool to hold the main line conductor K in compression. In this case, the conventional compression branch sleeve F has the following problems.

[0008] Since the fitting opening G is formed in the main wire holding portion H, if the fitting opening G is pressed against the main wire conductor K from the lateral direction, the main wire conductor K is inserted from the fitting opening G into the main wire holding portion H. Is pressed in, but if the frontage of the fitting opening G is not widened, the main line conductor K will not be pressed in easily into the main line holding portion H. Therefore, conventionally, the front opening K is widened so that the main conductor K is easily press-fitted. However, in this case, the main line conductor K press-fitted into the main line holding portion H is likely to come off.

[0009] In order to prevent the main wire conductor K from coming off from the fitting opening G, the main wire sandwiching portion H is compressed to
It was troublesome that the main line had to be held by a human hand, a robot hand, or the like until the sandwiching and holding was completed. In addition, since one hand is restrained to hold it, when a manual compressor is used to compress the main line holding portion H, the compressor must be operated with one hand, which makes the operation difficult. In some cases, it is difficult to work without two people,
It takes a lot of work.

[0010] When the fitting opening G of the main wire sandwiching portion H is a lateral opening, the fitting opening G is opened to the right so that the main wire sandwiching portion H can be covered from the right side of the main wire conductor K. It is necessary to separately prepare a branch sleeve and a left side compression branch sleeve in which the fitting opening G is opened to the left so that the branch sleeve can be covered from the left side. Therefore, the management of the compression branch sleeve F becomes troublesome,
In addition, when mounting the main wire conductor K, it is necessary to check the right one and the left one one by one, which is a troublesome work.

[0011] When connecting work using a manipulator or the like, the work is usually performed remotely from a position 2 to 3 m away, and therefore the main wire holding portion H is fitted to the main wire conductor K at a predetermined position due to an operation error. More than
The covering opening of the main wire is forcibly covered with the fitted opening G, and the covering portion is caught by the compression of the main wire holding portion H, or the fitted angle between the main wire conductor K and the main wire holding portion H is predetermined. The main wire holding portion H may be displaced from the position, and the main wire holding portion H may be compressed from an improper angle to cause a significant burr, and the wire conductor K may further protrude from the main wire holding portion H.
(FIG. 7) Or the electrical connection with the branch line E (FIG. 8) may become insufficient.

The object of the present invention is that the conductor can be temporarily held on the main wire conductor, and even one person can easily perform branching, edging, and other connection work, and there is no directionality for right and left directions, which is easy to work, and there is no deviation in connection position. It is difficult for mistakes such as biting of the main wire coating part,
An object of the present invention is to provide a compression branch sleeve in which working accuracy is improved, electrical connection between a main conductor and a branch conductor is ensured, working efficiency is improved, and working time is shortened.

When the branch line conductor 4 is crimped and held on the branch line sandwiching portion 5, both conductors 1 and 4 are electrically conducted through the compression branch sleeve. Moreover, at this time, since the main line conductor 1 can be temporarily held by the spring 6 provided in the main line holding portion 3, until the main line holding portion 3 is compressed and the main line conductor 1 is finally held.

[0025]

First Embodiment A first embodiment of a compression branch sleeve of the present invention will be described in detail with reference to FIGS. The compression branch sleeve shown in FIGS. 1 and 2 is made of aluminum casting, and the main wire holding portion 3 for crimping and holding the main wire conductor 1 obtained by peeling off the main wire covering portion 8 is attached to the main wire holding portion 3 as shown in FIG. 4a
The branch wire holding portion 5 for crimping and holding the branch wire conductor 4 peeled off is integrally formed at a predetermined angle. A fitting opening 2 is formed on the upper surface of the main line holding portion 3 so as to cover the main line conductor 1 over the entire length in the longitudinal direction, whereby the side surface shape of the main line holding portion 3 is an upward C-shape. It is in the shape of.
Further, the two facing rims 7 of the fitted opening 2 are made thicker than the other portions of the main line holding portion 3 so as not to be easily deformed,
Further, projecting portions 9 are provided at both ends of the mouth edge 7 in the longitudinal direction so as to face each other, and the width between the projecting portions 9 facing each other is made smaller than the outer diameter of the covering portion 8 of the main wire, so that the covering portion 8 is covered by the main wire. It is prevented from being press-fitted into the sandwiching portion 3 so that the covering portion 8 can be prevented from being caught.

At both ends in the longitudinal direction of the main line sandwiching portion 3 whose side surface shape is an upward C-shape, spring mounting portions 20 which are recessed one step along the inner peripheral surface thereof are formed, and the side surface shape is formed there. A C-shaped metal spring 6 is arranged, and a mounting portion 6a at the center of the spring 6 is fixed to the bottom surface of the main line holding portion 3 by a stop pin 21. The spring 6 has elasticity so that it can expand and contract in the radial direction, and its opening 6
The opening width of b is made slightly narrower than the diameter of the main line conductor 1 so that the main line conductor 1 can be press-fitted into the opening 6b, and unless the press-fitted main line conductor 1 is temporarily held by the spring 6 and forcibly pulled out. I try not to come out carelessly. The spring 6 is not fixed to the spring mounting portion 20 so that it does not move at all, but is mounted slightly loosely (with a degree of freedom) so that the direction, inclination, etc. of the spring 6 can be changed, and the main line conductor 1 is press-fitted. I made it easier. Further, the elasticity of the spring 6 is set so that the main conductor 1 can be freely press-fitted or removed by a human.

The main wire sandwiching portion 3 is compressed by a compression tool between two springs 6 at both ends in the longitudinal direction of the main wire conductor 1.
Is provided, and the length of the compression part 10 is made wider than the compression width of the compression tool, and the compression tool is compressed three times by sequentially shifting the position in the longitudinal direction of the compression tool. The whole is compressed. Therefore, in FIG. 1, arc-shaped partition grooves 22 are formed at four locations in the longitudinal direction of the compression section 10 to form the compression section 10 into three compression regions 10a, 1a.
It is divided into 0b and 10c to make it easy to understand one compression region. Further, each compression region of the compression unit 10 is colored directly, colored tape is attached, or the arcuate partition groove 22 is colored to make it easy to see from a distance. is there. Further, an arrow 23 is displayed on the surface of the compression portion 10 when the compression branch sleeve is formed to indicate the moving direction of the compression tool during compression.

Reference numerals 5 in FIGS. 1 and 2 denote branch line holding portions integrally formed with the main line holding portion 3. The branch line holding portions 5 are arranged in the longitudinal direction of the main line holding portion 3 as shown in FIG. About 30 from the bottom
It is projected obliquely downward at an inclination angle of °. This angle can be selected to any angle, but if it is set to about 30 °, the curving of the margin line when connecting the margin line and the main line is relaxed, and excessive stress is applied to the margin line and the main line. It also improves the aesthetics. Also, when connecting the main wires of the branch poles that are wired in a T-shape as shown in FIG. 8, the curvature of the branch wires is similarly relaxed, and the wires are not stressed and the appearance is improved. Further, the branch sleeve can be easily gripped even in an indirect method using a manipulator, a hot switch, or the like.

The branch line holding portion 5 is formed in a cylindrical shape, and the branch line conductor 4 can be inserted from an insertion port 25 formed at one end in the longitudinal direction of the branch line holding portion 5. The branch line conductor 4 inserted into the branch line sandwiching portion 5 is abutted against the bottom face 24 by blocking the connection side with the portion 3 to form a bottom face 24, and is prevented from being further inserted.
Further, a compression portion 26 is formed on the branch line holding portion 5. In FIG. 2, the length of the compression unit 26 is made wider than the compression width of the compression tool, and when the compression tool is sequentially changed in the longitudinal direction and the compression operation is performed twice, the entire compression unit 26 is compressed. is there. Further, in FIG. 1, circular ring-shaped partition grooves 31 are formed at three locations in the longitudinal direction of the compression portion 26 to divide the compression portion 26 into two compression regions 26a and 26b, and the respective compression regions 26 are divided.
It is easy to visually recognize a and 26b even from a distance. Also,
An arrow 27 is displayed on the surface of the compression portion 26 when the compression branch sleeve is formed to indicate the moving direction of the compression tool during compression.

The compression branch sleeve of the present invention comprises a compression section 10,
The length of 26 may be longer or shorter than shown. If the length is made longer, the compression length becomes longer, so that the main wire conductor 1 and the branch wire conductor 4 can be securely held and held, but the compression work becomes complicated because the number of times of compression by the compression tool increases. If the length is shortened, the number of times of compression is reduced, so that the compression work is facilitated. However, since the compression length is shortened, the main wire conductor 1 and the branch line conductor 4 may not be sufficiently held and held. Therefore, the compression unit 1
The lengths of 0 and 26 are selected so that the compression work is easy and the clamping and holding is sure.

Although it is not necessary to color the compression part 26 for visual recognition, the circular ring-shaped partition groove 31 is colored directly or by affixing a coloring tape, and the respective compression regions are confirmed. It can also be made easier.
