Description

[Technical Field]

[0001] The present invention relates to a wire bending tool. [Background technology]

[0002] In recent years, various proposals have been made regarding wire bending tools for bending electric wires. For example, among conventional tools, there is one that includes a Phillips head screwdriver part, a gripping part, and an electric wire bending tool part (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3244818 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the device disclosed in Patent Document 1, the wire bending tool part is provided on one side of the gripping part, and the screwdriver part is provided on the other side of the gripping part. Therefore, with the conventional device, after holding the gripping part by hand and bending the wire with the wire bending tool part, the user must once again hold the gripping part and then turn the screw with the screwdriver part, which can make the work complicated.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a wire bending tool that can improve workability. [Means for solving the problem]

[0006] In order to solve the above problem, the wire bending tool of the present invention comprises an attachment portion that is attached to a gripping portion, a driver portion that extends axially and is provided on one side of the attachment portion, a protrusion that protrudes radially outward from the outer peripheral surface of the driver portion, and a clamping portion that is provided on the tip side of the protrusion, sandwiching a space for inserting the wire between the outer peripheral surface of the driver portion. [Effects of the Invention]

[0007] According to one or more embodiments of the wire bending tool of the present invention, workability can be improved. [Brief explanation of the drawings]

[0009] [Embodiment] The following embodiments relate to the wire bending tool 10 shown in Figures 1 to 13 and include not only essential configurations but also optional and preferred configurations. Hereinafter, embodiments of the wire bending tool 10 will be described with reference to the accompanying drawings.

[0010] [First embodiment] 1 and 4 is used to bend a solid electric wire. The wire bending tool 10 is a tip tool (Phillips bit) with a cross-shaped tip portion 32 that has the function of tightening a Phillips head screw. In addition, the wire bending tool 10 has the function of bending an electric wire W, as will be described later.

[0011] The wire bending tool 10 includes an attachment portion 21, a driver portion 30, a protrusion portion 40, and a clamping portion 50.

[0012] The mounting portion 21 is formed into a shape that can be attached to the grip portion 20, and is attached to the grip portion 20. The grip portion 20 in this embodiment is formed, for example, in a cylindrical shape and extends in the axial direction. The grip portion 20 is the part that an operator holds in his / her hand. The driver 100 is formed by attaching the mounting portion 21 to the grip portion 20.

[0013] The driver portion 30 is provided on one side of the mounting portion 21 and is formed in a cylindrical shape extending in the axial direction. The driver portion 30 has a main body portion 31 and a tip portion 32. The driver portion 30 is a Phillips head screwdriver, and the tip portion 32 fits into a recess N2 formed in the head N1 of the screw N shown in FIG. 11.

[0014] As shown in FIGS. 2 and 3, the protrusion 40 protrudes outward in the radial direction R (see FIG. 2) relative to the outer circumferential surface 30R of the main body portion 31 of the driver portion 30.

[0015] The clamping portion 50 is provided on the axial tip side of the protrusion 40 with respect to the outer peripheral surface 30R of the driver portion 30, sandwiching a space 30S into which the electric wire W is inserted. The driver portion 30 and the clamping portion 50 are parallel to each other in the axial direction.

[0016] Next, an operation of bending the tip of the electric wire W using the electric wire bending tool 10 will be described with reference to FIGS.

[0017] As shown in FIG. 5, the worker first holds the gripping portion 20 with one hand and places the electric wire W in the space 30S located between the driver portion 30 and the clamping portion 50 with the other hand.

[0018] Next, the worker turns the gripping portion 20 in one circumferential direction (the direction of the arrow F1 in FIGS. 6, 7, 9 and 10) to bend the electric wire W along the outer peripheral surface 30R of the main body portion 31.

[0019] Next, the worker turns the gripping portion 20 in the other circumferential direction (the direction of the arrow F2 in FIGS. 7, 8, 9 and 10) to bend the wire W along the outer circumferential surface 30R of the main body portion 31.

[0020] Then, the worker continues to rotate the gripping portion 20 in the circumferential direction to bend the tip portion of the electric wire W into a "U" shape as shown in FIG.

[0021] Next, while holding the grip portion 20 with one hand, the worker inserts the tip portion 32 of the driver portion 30 into the recess N2 of the head N1 (see FIG. 11) of the screw N with the other hand (see FIG. 10).

[0022] Next, while holding the gripping portion 20 with one hand, the worker inserts the leg portion N3 of the screw into the portion W1 of the electric wire W that is bent into the "U" shape with the other hand.

[0023] Finally, the worker turns the gripping portion 20 in the circumferential direction and screws the wire W into the terminal fitting 61 of the outlet 60 (see FIG. 11).

[0024] Moreover, by repeating the same procedure as necessary, the electric wire W can be bent into an "U" shape. Furthermore, by changing the diameter of the driver part 30 and the diameter of the clamping part 50, it is possible to accommodate two different sizes of electric wires W.

[0025] The wire bending tool 10 according to this embodiment does not require the gripping portion 20 to be re-held when bending the wire W, thereby improving workability.

[0026] On the other hand, conventional wire bending devices include a driver unit provided on one axial end of a gripping unit and a wire bending tool unit provided on the other axial end of the gripping unit, so that with conventional wire bending devices, after bending the wire with the wire bending tool unit, the user must re-hold the gripping unit and then use the driver unit to attach the screw.

[0027] [Second embodiment] Next, a second embodiment of a screwdriver 100A having the wire bending tool 10 will be described with reference to Fig. 12. The attachment portion 21 of the wire bending tool 10 can be attached to the grip portion 29. Then, by attaching the attachment portion 21 to the grip portion 29, an electric screwdriver 100A is formed.

[0028] [Third embodiment] Next, a third embodiment of the wire bending tool 10B will be described with reference to Fig. 13. A groove 38 for arranging the wire W to be bent is formed in the main body portion 31 of the driver part 30 of the wire bending tool 10B according to this embodiment, in a portion facing the clamping part 50.

[0029] The disclosure of the present invention described above can be summarized at least as follows.

[0030] The wire bending tool 10 comprises an attachment portion 21 attached to the gripping portion 20, a driver portion 30 extending in the axial direction and provided on one side of the attachment portion 21, a protrusion portion 40 protruding radially outward from the outer peripheral surface 30R of the driver portion 30, and a clamping portion 50 provided on the tip side of the protrusion portion 40, sandwiching a space portion 30S into which the wire W is inserted, relative to the outer peripheral surface 30R of the driver portion 30.

[0031] The present invention disclosed in the above paragraph 0028 may include at least the following embodiments, which may be adopted separately or in combination with each other.

[0032] (1) The clamping portion 50 is parallel to the driver portion 30. (2) The body portion 31 of the electric wire bending tool 10B has a groove 38 formed in a portion facing the clamping portion 50, in which the electric wire W to be bent is placed. [Explanation of symbols]
