接触圧が得られないという問題点がある。 As shown in Fig. 1, the retaining clamp consists of a steel sleeve 1 that is compressively connected to the end of the electric wire W, and an aluminum sleeve 2 that is compressively connected to the outside of this steel sleeve 1.
and a jumper socket 3 connected to this aluminum sleeve 2. When installing this retaining clamp, first attach the steel sleeve to the end of the wire W.
are compression-connected, and then an aluminum sleeve 2 is compression-connected to the outside thereof. This compression of the aluminum sleeve 2 is performed sequentially from the wire W side toward the end side of the steel sleeve 1 in order to prevent untwisting phenomenon caused by elongation of the aluminum strands of the wire W. Aluminum sleeve 2 and steel sleeve 1 have holes 1 for inserting bolts.
a and 2a are formed, but when connecting the two, it is necessary to match them. The aluminum sleeve 2 expands toward the end of the steel sleeve 1 due to compression, so in order to align the holes 1a and 2a, take this expansion into account in advance when adjusting the aluminum sleeve 2.
determine the position. However, the aluminum sleeve 2 has different degrees of elongation due to variations in material quality. Therefore, the holes 1a and 2a are elongated holes extending in the direction of extension. However, in the case of using a long hole, there is a problem that distortion occurs in the aluminum sleeve 2 when tightened with a bolt, and good contact pressure against the steel sleeve 1 cannot be obtained.

Attach one contact 8 to the end of the aluminum sleeve 2,
The other contacts 9 are applied to the flanges 1b of the steel sleeve 1, respectively, and the compressor 4 is operated. The aluminum sleeve 2 is expanded by compression by the compressor 4, and the distance between the end thereof and the collar 1b of the steel sleeve 1 is narrowed. At the same time, the contacts 8 and 9 move, and when a predetermined distance between the holes 1a and 2a is reached, the measuring device 7 emits an electric signal. This signal causes the solenoid valve 11 to operate, cutting off the oil supply from the pump device 5 to the compressor 4 and ending the compression operation.

A measuring device 7 has a pair of measuring contacts 8 and 9 applied to the collar 1b and the end of the aluminum sleeve 2, respectively, and emits an electric signal when the measuring contacts 8 and 9 reach a certain distance. , and a solenoid valve 11 that is attached to the hydraulic pump device 5 and cuts off the oil supply from the hydraulic pump device 5 to the compressor 4 in response to a signal from the measuring device 7, so that the end of the aluminum sleeve 2 is in a predetermined position. The compression operation can be terminated when it is reached.
For this reason, it is sufficient to drill a round hole in the aluminum sleeve 2 instead of the long hole 2a for bolt insertion, and the presence of the long hole can eliminate the strain that occurs in the aluminum sleeve 2. A reliable contact state with the sleeve 1 can be obtained.
