The inner diameter of such an adjusting member 205 is set to be the same as the outer diameter of the other trunk cable 3 inserted into the bolt fastening portion 15, and the inner peripheral surface of the adjusting member 205 has a plurality of (here, two) bolts. It is arranged so as to face the screw hole 33.

Therefore, by inserting the other trunk cable 3 into the bolt fastening portion 15 with the adjusting member 205 arranged at the bolt fastening portion 15, the outer peripheral surface of the other trunk cable 3 on the opposite side to the bolt screw hole 33. Is arranged on the inner peripheral surface of the adjusting member 205, and the adjusting member 205 is arranged so as to fill the space between the outer circumference of the other trunk cable 3 and the inner circumference of the bolt fastening portion 15.

From this state, by fastening the bolt 13 to the bolt screw hole 33 of the bolt fastening portion 15, the connector main body 5 and the other trunk cable 3 are electrically connected via the adjusting member 205, and the pair of trunk cables 3 are connected. , 3 are electrically connected, and the connector body 5 is fixed to the other trunk cable 3. The head 25 of the bolt 13 is cut by a predetermined fastening force.

By filling the space between the outer circumference of the other trunk cable 3 and the inner circumference of the bolt fastening portion 15 with the adjusting member 205 in this way, the other adjusting member 205 is inserted into the bolt fastening portion 15 in a state where the adjusting member 205 is not arranged. A cross-sectional area equivalent to that in the state where the trunk cable 3 is inserted into the bolt fastening portion 15 can be obtained, the compression ratio of the other trunk cable 3 after fastening the bolt 13 is equalized, and the mechanical and electrical performance is satisfied. be able to.

In addition, since the semicircular adjusting member 205 is arranged so as to face the screw hole 33 for the bolt, when the bolt 13 is fastened, the other trunk cable 3 is prevented from spreading due to the pressing of the bolt 13. It is possible to satisfy the mechanical and electrical performance.

After assembling the connector 1 to the pair of trunk cables 3 and 3, the connector 1 is provided around the connector 1 with an insulating member 37 such as a self-bonding tape or a shrinkable tube in order to ensure insulation and waterproofness. Is covered.

In such a connector 1, the crimping portion 11 and the bolt fastening portion 15 of the connector body 5 are located between the outer circumferences of the pair of trunk cables 3 and 3 and the inner circumference of the crimping portion 11 and the inner circumference of the bolt fastening portion 15, respectively. Since the adjusting members 203 and 205 that fill the above are arranged, one connector body 5 can be used for a pair of trunk line cables 3 and 3 having various outer diameters, and the connector body 5 can be used for general purposes. The sex can be improved.

In the connector according to the embodiment of the present invention, the number of bolts to be fastened to the connector main body or the branch connector main body is two, but the present invention is not limited to this, and the number of bolts to be fastened is three or more or one. May be good.

The polygonal shape of the connector body is hexagonal, but the shape is not limited to this, and any shape may be used as long as it is a polygonal shape such as a triangle, a quadrangle, or a heptagon.

Further, the outer shape of the other end of the connector body to which the bolt is fastened is formed to be polygonal, but the present invention is not limited to this, and the entire outer shape of the connector body may be formed to be polygonal.

Further, the adjusting member arranged at the bolt fastening portion of the connector body is formed in a semicircular shape, but is not limited to this, and the adjusting member is formed in an annular shape and a hole is formed at a position corresponding to the screw hole for the bolt. Or screw holes may be provided.
