Description

  The present invention relates to a wire rod attaching / detaching tool for attaching / detaching a plurality of wire rods to / from a clamp type connector board in which a plurality of clamp type connector portions are arranged.

  FIG. 1 shows an example of a clamp-type connector unit included in a plurality of clamp-type connector boards of this type. The clamp-type connector unit 600 includes two rows including two clamp-type connector portions, and a total of four clamp-type connector portions. In FIG. 1, the inside of the clamp-type connector unit 600 is shown in a perspective manner.

  Referring to FIG. 1, each clamp-type connector portion has a base portion 610 and a shaft portion 620 that are a part of an insulator having an insulating property of the clamp-type connector unit 600, and conductivity disposed adjacent to the base portion 610. A spring piece which is provided with a terminal 630 formed by bending a sheet metal having a substantially L shape and a substantially six shape formed by winding a sheet metal band having elasticity, and is attached to the shaft portion 620 so as to surround it. 640.

  The terminal 630 includes a contact portion 630a on one side of the L shape. The spring piece 640 includes a hole 640a at the end thereof. When there is no restriction, the spring piece 640 operates in a direction in which the winding expands due to elasticity. The wire 700 is inserted into the hole 640 a of the spring piece 640 and is pressed against the contact part 630 a of the terminal 630 by the elasticity of the spring piece 640. As a result, electrical continuity is established between the terminal 630 and the wire 700.

  The wire 700 is removed from and attached to the clamp-type connector board as follows.

  When a plurality of wires 700 are already mounted on the clamp-type connector board, the user inserts a minus driver 60 having a flat bit between the base 610 and the spring piece 640 and tilts the minus driver 60. Thus, the winding of the spring piece 640 is contracted to maintain the state in which the spring piece 640 is not held by the wire 700, and during this time, the wire 700 is removed from the hole 640a of the spring piece 640, and then the minus driver 60 Unplug. Thereafter, the same operation is repeated for each clamp connector portion.

  On the other hand, when attaching a plurality of wires 700 to the clamp-type connector board, the user inserts the minus driver 60 between the base 610 and the spring piece 640 and tilts the minus driver 60 to wind the spring piece 640. The state in which the spring piece 640 is released from the holding of the wire 700 is maintained by shrinking the turn, and the wire 700 is inserted into the hole 640a of the spring piece 640 during this time, and then the minus driver 60 is removed. Thereafter, the same operation is repeated for each clamp connector portion.

  Such a clamp-type connector panel is a one-touch operation in which the spring piece is deformed with a flat-blade screwdriver to release the holding to the wire, compared to a screw-type switchboard that fastens the terminals attached to the ends of the wire with screws. Because it can be attached and detached, it has excellent work efficiency.

  A driver tool for collectively tightening or loosening a plurality of screws of a screw-type switchboard in order to attach and detach a plurality of wire terminals to and from a screw-type switchboard is disclosed in Patent Documents 1 and 2, for example. Is disclosed.
