At this time, the lower surface of the guide cylinders 52 2 a and 52 2 b of the upper clamper 520 abuts on the upper surface 211 A of the sheet metal 211.

From the above, in this embodiment, since three wires 400 can be arranged side by side and fixed by one wire clamper 500, it is necessary for wire fixing as compared with the method of fixing each wire 400 with an individual wire clamper. Space can be reduced. Further, when fixing each wire 400 with an individual wire clamper, two screws are required to fix one wire, so six screws are required for three wires. In this embodiment, only four screws are required.

Further, since the wire guide portions 513a to 513c are formed in the lower clamper 510, the outer cover 410 of the wire 400 can be guided there, and the wire 400 can be prevented from being displaced from the normal position. , Workability of temporary wire fixing is improved.

Further, the guide cylinders 522a and 522b of the upper clamper 520 are engaged with the guide holes 512a and 512b of the lower clamper 510, and the lower clamper 510 is connected to the locking holes 211a and 211b of the sheet metal 211 by the temporarily fixing locking pieces 515a and 515b. After locking, the upper clamper 520 is locked to the locking holes 212a and 212b of the sheet metal 211 by the temporary fixing locking pieces 527a and 527b.

Therefore, the upper clamper 520 and the lower clamper 510 are temporarily fixed to the sheet metal 211 with the wire 400 sandwiched between the wire guide portions 513a to 513c of the lower clamper 510 and the wire guide portions 523a to 523c of the upper clamper 520. can do. Therefore, it is possible to prevent the upper clamper 520 and the lower clamper 510 from falling when the screws 701 to 704 are tightened or removed, and workability is improved.

Further, in the upper clamper 520, the lower surfaces 520B of the guide cylinders 522a and 522b come into direct contact with the upper surface 211A of the sheet metal 211 of the upper terminal block 210 via the guide holes 512a and 512b of the lower clamper 510, which is excessive to the wire 400. The wire 400 can be securely fixed without applying the pressure of.
