Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter for cutting a bundle of wire rods, and more particularly to a cutter for cutting a bundle of wire rods such as a wire harness, which can easily cut a tape for binding the bundle of wire rods.

[0002]

2. Description of the Related Art Generally, a wire bundle such as a wire harness mounted on an automobile or an electric device is formed in a harness shape by bundling a plurality of electric wires with a tape. By the way, it is necessary to disassemble the electric wire when re-binding the electric wire harness or reusing the electric wire, and in this case, it is necessary to remove the tape.

In order to perform such work, conventionally,
As shown in FIG. 3, the worker searches for the winding end 2a of the tape 2 wound around the outer peripheral portion of the wire harness 1, and
The tape 2 was unwound from a. However,
In such an operation, it takes a very long time to find the winding end 2a of the tape 2, so that the workability is very poor. To solve such a problem, FIG.
As shown in (a), a bifurcated cutter 3 composed of a long part 3a and an end part 3b is used, and the end part 3b of the cutter 3 is used.
Is inserted between the tapes 2 as shown in FIG. 4 (b), and then the cutter 3 is moved in the direction of arrow B,
The tape 2 was cut.

[0004]

However, in the case of cutting the tape 2 using the cutter 3, the end portion 3b of the cutter 3 is inserted between the tapes 2 and the arrow B is cut.
Since the cutter 3 is moved in the direction, the workability of the cutting operation of the tape 2 can be improved, but there is a possibility that the cutter 3 may damage the electric wire in the tape 2.

Accordingly, an object of the present invention is to provide a tape cutting cutter for a wire bundle that can easily cut a tape without damaging the wire.

[0006]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, a cutter for cutting a wire bundle used when disassembling a wire by removing a tape from a wire bundle in which a plurality of wires are bundled by a tape, comprising: A main body having a curved shape so as to be able to contact a part of the direction, and a cutter member protruding from an inner peripheral surface of the main body, wherein a protruding length of the cutter member is adjustable. It is assumed that.

In this case, the tape can be easily cut by bringing the inner peripheral surface of the main body into contact with the outer peripheral portion of the wire bundle, inserting the cutter portion into the tape, and moving the main body as it is in the extending direction of the wire bundle. Can be. At this time, since the protrusion length of the cutter member is adjustable, by adjusting the length of the cutter portion according to the thickness of the tape, only the tape can be cut without damaging the wire.

According to a second aspect of the present invention, in order to solve the above-mentioned problem, in the first aspect of the present invention, a handle is provided on an outer peripheral surface of the main body. In this case, since the main body can be moved by gripping the handle, the workability of the tape cutting operation can be further improved. According to a third aspect of the present invention, in order to solve the above problem, in the first or second aspect of the present invention, the main body has an elastic force.

In this case, even when the main body is manufactured according to the minimum diameter wire bundle, the main body is deformed along the outer peripheral surface of the wire bundle when the main body is brought into contact with the maximum diameter wire bundle. In addition, it is possible to reliably cut a tape of a wire bundle of any diameter.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing one embodiment of a cutter for cutting a tape of a wire bundle according to the present invention. First, the configuration will be described. In FIGS. 1 and 2, reference numeral 11 denotes a wire harness (wire bundle), and a plurality of electric wires (wires) 12 are bundled by a tape 13 in the wire harness 11.

Reference numeral 14 denotes a cutting cutter. The cutting cutter 14 has a main body 15 having a curved shape so as to be able to contact a part of the wire harness 11 in the circumferential direction. The main body 15 is made of an elastic member and has an elastic force. A cutter 16 having a blade 16a formed at the distal end thereof is screwed into the main body 15, and by rotating a knob 16b formed at the base end of the cutter 16, the main body of the cutter 16a is rotated. The protrusion length of the 15 from the inner peripheral surface is adjustable.

A handle 17 is provided on the outer peripheral surface of the main body 15, and this handle 17 can be gripped by an operator. The tape 13 is cut by such a cutting cutter 14.
In order to cut the tape, first of all,
After adjusting the protruding length of the cutter portion 16 with respect to the inner peripheral surface of the main body 15 (preferably, the length is such that the blade 16a is inserted to about half the thickness of the tape 13), the inner peripheral surface of the main body 15 is wired. The blade 16a is inserted into the tape 13 by making contact with the outer peripheral portion of the harness 11, the handle 17 is gripped, and the main body 15 is moved in the extending direction of the wire harness 11 as a tape.
Cut 13 After this, disassemble the electric wire and wire harness
Re-bundling 11 or reusing wires.

As described above, in this embodiment, the blade 16a is inserted into the tape 13 by bringing the inner peripheral surface of the main body 15 into contact with the outer peripheral portion of the wire harness 11, and the main body 15 is directly connected to the wire harness 11.
By moving the tape 13 in the extending direction, the tape 13 can be easily cut. At this time, since the protrusion length of the cutter member 16 is adjustable, by adjusting the length of the cutter portion 16 according to the thickness of the tape 13, it is possible to cut only the tape 13 without damaging the wire harness 11. Can be.

Further, since the handle 17 is provided on the outer peripheral surface of the main body 15, the main body 15 can be moved by gripping the handle 17, and the workability of the cutting operation of the tape 13 can be further improved. Furthermore, since the main body 15 has elasticity,
Even when the main body 15 is manufactured according to the minimum diameter wire harness 11, when the main body 15 is brought into contact with the maximum diameter wire harness 11, the main body 15 is deformed along the outer peripheral surface of the wire harness 11, Wire harness 11 tape of any diameter
Even 13 can be cut reliably.

[0015]

According to the first aspect of the present invention, the cutter is inserted into the tape by bringing the inner peripheral surface of the main body into contact with the outer peripheral portion of the wire bundle, and the main body is moved in the extending direction of the wire bundle as it is. This makes it easy to cut the tape. At this time, since the protrusion length of the cutter member is adjustable, by adjusting the length of the cutter portion according to the thickness of the tape, only the tape can be cut without damaging the wire.

According to the second aspect of the present invention, since the main body can be moved by gripping the handle, the workability of the tape cutting operation can be further improved. According to the third aspect of the present invention, even when the main body is manufactured according to the wire bundle having the minimum diameter, when the main body is brought into contact with the wire bundle having the maximum diameter, the main body is formed along the outer peripheral surface of the wire bundle. Therefore, it is possible to reliably cut even a tape of a wire bundle of any diameter.
