Description

[Technical Field]

[0001] The present invention relates to a wire bending jig for making, for example, jumper wires. [Background technology]

[0002] Conventionally, to make a jumper wire, a worker would cut the conductor with nippers or the like, and then bend the left and right ends of the wire using pliers.

[0003] Patent document 1 also discloses a lead wire bending jig that includes a two-plate block having a plate-shaped hinged portion that bends from the center in the longitudinal direction and has grooves of the same dimensions on both sides in several places centered on the point where it bends on the longitudinal side, and a fixing bracket for fixing the two-plate block when it is bent at a fixed angle from a part of the block. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 63-114100 Summary of the Invention [Problem to be solved by the invention]

[0005] When workers create jumper wires by hand using nippers or pliers, there is variation in the length of the cut, the length of the bend, the direction, and the angle depending on the worker, which can lead to problems such as improper installation when attaching the jumper wire to a wiring board, etc.

[0006] Even if the jig disclosed in Patent Document 1 is used, the ends of the lead wires are cut according to the worker's guide after bending, resulting in variations in the lengths of the bent ends of the lead wires. Also, with the jig disclosed in Patent Document 1, the two ends of the lead wires may be bent in different directions, making it difficult to form them into the desired shape.

[0007] An object of one aspect of the present invention is to provide a conductor bending jig that can efficiently manually produce a conductor bent at two points. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the conductor bending jig of the present invention is a conductor bending jig for bending a conductor, and comprises: a main body having a first main body surface; a first lid surface that can face the first main body surface at a predetermined distance; and a lid having a second lid surface that forms a predetermined angle with the first lid surface. The main body comprises: a conductor end holding portion that is provided at a predetermined position on the first main body surface and holds one end of the conductor inside the main body; a first bending portion that is provided at the predetermined position on a surface that includes the first main body surface; and a second bending portion that is provided at a predetermined distance from the first bending portion on the surface that includes the first main body surface. When the first lid surface faces the first main body surface, the second lid surface is configured to be spaced a predetermined distance from the second bending portion.

[0009] In the above configuration, a conductor whose end is held by the conductor end holder is first bent by the user at the first bending portion of the main body. Then, when the lid is placed in the opposing position, the conductor is pressed against the first and second lid surfaces and bent at the second bending portion. That is, with the above configuration, the conductor can be bent in a predetermined direction and at a predetermined angle at two locations: a position at a first length from one end of the conductor, and a position at a second length from the first length. This provides a conductor bending jig that can efficiently manually create conductors bent at two locations, such as jumper wires.

[0010] Furthermore, in the above-described configuration, the conductor bending jig according to the present invention may be configured such that the first body side surface and the second lid side surface are flat, the angle between the first lid side surface and the second lid side surface is approximately 90 degrees, and the angle between a line connecting the conductor end holding portion and the first bending portion and a plane including the first body side surface is approximately 90 degrees.

[0011] According to the above configuration, the conductor can be bent at approximately 90 degrees at a position where the conductor is a first length from one end of the conductor, and at a position where the conductor is a second length from the first length, thereby providing a conductor bending jig that can efficiently manually create a conductor having three sides of a rectangle, such as a jumper wire. Furthermore, in the above-described configuration of the wire bending jig according to the present invention, the main body may further include a main body side surface at the location where the second bending portion is formed, the main body side surface having a planar shape and a height from a plane including the main body first surface equal to the depth to a plane including the main body first surface of the wire end holding portion. According to the above configuration, when the first cover surface is disposed in the opposing position, the conductive wire can be securely sandwiched and bent, while the shape of the portion other than the bent portion can be straightened. Furthermore, in the above-described configuration of the conductor bending jig according to the present invention, the main body may have a groove portion located between the first bending portion and the second bending portion, the groove portion extending in a direction connecting the first bending portion and the second bending portion.

[0012] According to the above configuration, after bending the conductor at the first bending portion, the user can easily guide the conductor to the second bending portion. This improves user operability. Furthermore, when the conductor arranged between the first bending portion and the second bending portion is pressed by the first surface of the cover, displacement of the conductor can be suppressed.

[0013] In the conductor bending jig according to the present invention, in the above configuration, the groove may extend from the first bent portion to the second bent portion.

[0014] According to the above configuration, the conductor wire can be easily guided along the groove extending from the first bent portion to the second bent portion.

[0015] Furthermore, in the above-described configuration of the conductor bending jig according to the present invention, the groove may be provided in a groove laying member that is movable in a direction perpendicular to the first surface of the main body, and the groove laying member may be provided with a biasing member that biases the groove laying member in a direction protruding from a surface that includes the first surface of the main body.

[0016] With the above configuration, when the cover is placed in the opposing position, the groove laying member can be configured to sink into the main body appropriately depending on the thickness of the conductor, thereby making it possible to increase the size and depth of the groove to some extent, making it easier to guide the conductor into the groove.

[0017] In addition, in the above-described configuration of the conductor bending jig according to the present invention, the conductor end holding portion may be a hole portion, the inner diameter of the hole near the bottom surface may be approximately the same as the outer diameter of the conductor, and the spacing may be approximately the same as the outer diameter of the conductor.

[0018] With the above configuration, one end of the conductor is fixed at a predetermined position near the bottom surface of the hole, and the conductor can be fixed between the first lid surface and the first body surface when the first lid surface is positioned opposite to the hole, thereby making it possible to straighten the shape of the conductor other than the bent portion.

[0019] In addition, the conductor bending jig of the present invention may be configured in the above-mentioned manner to include a cutting member that cuts the conductor protruding from the end of the second surface of the lid in the extension direction when the first surface of the lid is facing the first surface of the main body.

[0020] According to the above configuration, when the first cover surface is positioned in the opposing position, the conductor protruding from the end of the second cover surface in the extension direction can be cut off, and the bent conductor can be cut and shaped into a predetermined shape such as a jumper wire.

[0021] In addition, in the above-described configuration of the conductor bending jig of the present invention, the cutting member may be configured to cut the conductor at a position where the distance from the second bending portion is equal to the depth from a plane including the first main body surface of the conductor end holding portion.

[0022] According to the above configuration, it is possible to create a conductor having a shape in which the length from one end of the conductor to the point where it is bent by the first bending portion is equal to the length from the other end of the conductor to the point where it is bent by the second bending portion.

[0023] In addition, in the above-mentioned configuration, the conductor bending jig of the present invention may be configured so that the conductor end holding portion and the first bending portion are provided on a main body movable portion that is movable in a direction connecting the first bending portion and the second bending portion.

[0024] According to the above configuration, the positions of the conductor end holder and the first bending portion can be moved, and therefore the distance between the first bending portion and the second bending portion can be changed, thereby providing a conductor bending jig that can variably change the second length of the conductor. [Effects of the Invention]

[0025] The present invention has the effect of providing a conductor bending jig that can efficiently manually produce a conductor such as a jumper wire that is bent at two points. [Brief explanation of the drawings]

[0027] [Embodiment 1] Hereinafter, an embodiment according to one aspect of the present invention (hereinafter also referred to as "the present embodiment") will be described with reference to the drawings. However, the present embodiment described below is merely an example of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In other words, when implementing the present invention, specific configurations according to the embodiment may be appropriately adopted.

[0028] §1 Application Examples First, we will explain an outline of an application example of the conductor bending jig 1. As shown in Fig. 1, the conductor bending jig 1 includes a main body 2 having a main body first surface 21, a lid 3 having a lid first surface 31 that can be arranged in an opposing position facing the main body first surface 21 at a predetermined distance, and a lid second surface 32 that is provided at a predetermined angle relative to the lid first surface 31.

[0029] The main body 2 includes a first bending portion 22 provided at a predetermined position on a surface including the first main body surface 21, a hole (conductor end holder) 24 for holding one end of a conductor at a position in the first bending portion 22 that is a predetermined first length from the surface including the first main body surface 21, and a second bending portion 23 provided at a position a predetermined second length from the first bending portion 22 on the surface including the first main body surface 21. Note that the "end of the conductor" here refers to the portion between one tip of the conductor and the predetermined position where it is to be bent by the first bending portion 22. The shape of the conductor end holder 24 is not particularly limited to a hole, and may be any shape that can hold one end of the conductor at a predetermined angle with respect to the first main body surface 21. As another example, the conductor end holding portion 24 may be a groove portion that is arranged on a surface including the first main body surface 21 so as to be perpendicular to the straight line connecting the first bent portion 22 and the second bent portion 23, and has a depth equal to the first length of the conductor that is expected to be used, and a width approximately the same as the outer diameter of the conductor.

[0030] When the lid body side first surface 31 is positioned in an opposing position, the lid body side second surface 32 extends outside the second bending portion 23 relative to the main body 2, in a direction from the plane including the main body side first surface 21 toward the main body side, i.e., vertically downward.

[0031] In the above configuration, as shown in FIG. 3 , the user first bends the conductor 5, whose end is held by the hole 24, at the first bending portion 22 of the main body. Then, when the lid 3 is placed in the opposing position, the conductor 5 is pressed by the first lid surface 31 and the second lid surface 32 and bent at the second bending portion 23. That is, with the above configuration, the conductor 5 can be bent in a predetermined direction and at a predetermined angle at two positions: a position at a first length from one end of the conductor 5, and a position at a second length from the first length. This makes it possible to efficiently manually create conductors 5 bent at two positions, such as jumper wires.

[0032] §2 Configuration example [Embodiment 1] The structure of a conductor bending jig 1 according to one embodiment of the present invention will be described in more detail below. FIG. 1 is a side cross-sectional view showing a schematic configuration of the conductor bending jig 1. As shown in the figure, the conductor bending jig 1 has a main body 2 and a lid 3 connected by a pivot shaft 33. That is, the lid 3 is rotatable relative to the main body 2 around the pivot shaft 33. As an example of the pivot shaft 33, the main body 2 and the lid 3 may be connected by a hinge. As another example, the main body 2 and the lid 3 may be connected by a single shaft member passing through them. Furthermore, the pivot shaft 33 may be a member having elasticity, such as a spring hinge, which may be used to connect the lid 3 so as to bias the main body 2 upward.

[0033] A flat main body-side first surface 21 is provided on the top surface of the main body 2. A hole 24 is provided in the main body-side first surface 21. A first bent portion 22 is provided on the opening of the hole 24 on the side farther from the pivot shaft 33. In other words, the first bent portion 22 is the apex of the angle formed by the side surface of the hole 24 and the main body-side first surface. Because the first bent portion 22 is a location where force is applied when the conductive wire 5 is bent, it is preferably made of a wear-resistant material such as metal, but the material is not particularly limited.

[0034] The angle formed by the side surface of hole 24 on the first bent portion 22 side and the first body-side surface, i.e., the angle formed by the line connecting the side surface near the bottom surface of hole 24 serving as the conductor end holder on the first bent portion 22 side and first bent portion 22 and the plane including the first body-side surface, is 90 degrees. Note that the angle formed by the side surface of hole 24 and the first body-side surface may be approximately 90 degrees, i.e., may include an error of a few degrees from 90 degrees. Furthermore, even if the error is greater than a few degrees, it is sufficient as long as the angle is large enough to allow the end of the bent conductor to be inserted into the hole in the wiring board.

[0035] The side surface of hole 24 is perpendicular to first body-side surface 21. However, the side surface facing in a direction different from the first bent portion 22 side may be inclined with respect to first body-side surface 21. In other words, hole 24 may be cone-shaped on a side other than the side facing first bent portion 22. In this shape, the opening shape of hole 24 can be widened, making it easier to insert conductive wire 5.

[0036] A second bent portion 23 is provided at one end of the first main body surface 21. Because second bent portion 23 is the location where force is applied when conducting wire 5 is bent, it is preferably made of a material that is resistant to wear, such as metal, but the material is not particularly limited.

[0037] Furthermore, where the second bent portion 23 is formed, a body-side side surface 25 is provided that has a planar shape perpendicular to the body-side first surface 21. In other words, the second bent portion 23 is the vertex of the angle formed by the body-side first surface 21 and the body-side side surface 25. The angle formed by the body-side first surface 21 and the body-side side surface 25 is 90 degrees. Note that the angle formed by the body-side first surface 21 and the body-side side surface 25 may be approximately 90 degrees, that is, may include an error of a few degrees from 90 degrees. Furthermore, even if the error is greater than a few degrees, it is sufficient that the angle is such that the end of the bent conductor can be inserted into a hole in the wiring board.

[0038] In addition, the angle formed by the first lid-side surface 31 and the second lid-side surface 32 of the lid 3 is 90 degrees. When the lid 3 is placed in the opposing position, that is, at a position where the first lid-side surface 31 faces the first body-side surface 21 at a predetermined distance, the second lid-side surface 32 and the body-side side surface 25 face each other at a predetermined distance.

[0039] It is preferable that the first surface 31 on the lid side and the second surface 32 on the lid side, particularly the area that comes into contact with the conductive wire 5, be made of a material that is resistant to wear, such as metal, but the material is not particularly limited.

[0040] The depth of hole 24 is a predetermined first length. The inner diameter of hole 24 near the bottom is approximately the same as the outer diameter of conductor 5 that is expected to be used. This allows the end of conductor 5 inserted into hole 24 to be fixed at a predetermined position near the bottom of hole 24.

[0041] Furthermore, when the lids 3 are disposed in the opposing position, the distance between the lid-side first surface 31 and the body-side first surface 21 is approximately the same as the outer diameter of the conductor 5. Similarly, when the lids 3 are disposed in the opposing position, the distance between the lid-side second surface 32 and the body-side side surface 25 is approximately the same as the outer diameter of the conductor 5. This allows the conductor 5 to be fixed between the lid-side first surface 31 and the body-side first surface 21, and between the lid-side second surface 32 and the body-side side surface 25, when the lids 3 are disposed in the opposing position. Therefore, the conductor 5 can be securely sandwiched and bent, while the shape of the parts other than the bent parts can be straightened.

[0042] The lower end of body-side side surface 25 is formed up to a position where the distance from second bent portion 23 is a predetermined third length, and a lower body-side side surface is formed inward from the lower end of body-side side surface 25. In other words, the portion where second bent portion 23 is formed has a shape that protrudes laterally by the width of body-side side surface 25. Due to this shape, conductive wire 5 that is bent at second bent portion 23 and thus protrudes downward from the lower end of body-side side surface 25 can be easily cut at a position where the distance from second bent portion 23 is the predetermined third length.

[0043] Further, groove 26 is provided on first main body surface 21 so as to connect first bent portion 22 and second bent portion 23 in a straight line. Groove 26 is formed so that its depth is shorter than the outer diameter of conductor 5. For example, groove 26 is preferably formed to be approximately 0.1 to 0.3 times the outer diameter of conductor 5 expected to be used. The cross-sectional shape of groove 26 is not particularly limited, and examples include an arc shape, a triangle shape, and a rectangle shape. The provision of groove 26 in this manner allows the user to easily guide conductor 5 to second bending portion 23 after bending conductor 5 at first bending portion 22. This improves user operability. Furthermore, when conductor 5 arranged between first bending portion 22 and second bending portion 23 is pressed by first cover-side surface 31, displacement of conductor 5 can be suppressed.

[0044] 1, groove 26 is formed extending from first bent portion 22 to second bent portion 23. This allows conductor 5 to be accurately guided and positioned from first bent portion 22 to second bent portion 23. Groove 26 may be formed only in a partial region between first bent portion 22 and second bent portion 23. Groove 26 may also be provided on main body side surface 25. Furthermore, grooves may also be provided on cover body first surface 31 and cover body second surface 32.

[0045] 2 is a plan view of the first main body surface 21 as viewed from above. In the example shown in the figure, the groove 26 is formed as two grooves 26A and 26B of different lengths. Also, the hole 24, the first bent portion 22, and the second bent portion 23 are each provided in pairs, i.e., hole 24A and 24B, first bent portion 22A and 22B, and second bent portion 23A and 23B. In other words, this configuration example allows the conductive wire 5 to be bent to two different second lengths.

[0046] In the example shown in Figure 2, there are two sets of hole portion 24, first bent portion 22, second bent portion 23, and groove portion 26, but the number of these sets is not limited and may be one set or three or more sets.

[0047] The sets of grooves 26 are not limited to sets of different lengths, but may be sets of the same length. According to this configuration example, it is possible to simultaneously bend a plurality of conductive wires 5 to correspond to one type of second length.

[0048] 3 is a diagram showing the process of bending the conductor 5. First, as shown in 3001, the user lifts the lid 3 to open the upper part of the first main body surface 21, and inserts one end of the conductor 5 into the hole 24. Next, as shown in 3002, the user bends the conductor 5 at the first bending portion 22 and arranges it along the groove 26 until it contacts the second bending portion 23.

[0049] Next, as shown in 3003, the user rotates the lid 3 to the facing position, i.e., to a position where the lid first surface 31 faces the body first surface 21 at a predetermined distance. As a result, the lid second surface 32 comes into contact with the conductor 5, and the conductor 5 is bent at the second bending portion 23. In this state, the conductor 5 is sandwiched between the lid first surface 31 and the body first surface 21, and also sandwiched between the lid second surface 32 and the body side surface 25. That is, this bending process keeps the portions of the conductor 5 other than the bent portions straight, and the conductor 5 can be bent into a desired neat shape.

[0050] Then, as shown in 3004, the conductor 5, which protrudes downward from the lower end of the second surface 32 on the lid side and the lower end of the side surface 25 on the main body side, is cut by the user using any cutting means such as nippers at a position where the distance from the second bending portion 23 is a predetermined third length.

[0051] Through the above process, a conductor 5 can be efficiently produced manually, having a shape that forms three sides of a rectangle, bent 90 degrees at a first length from one end and bent 90 degrees at a third length from the other end, and having a predetermined second length.

[0052] In this embodiment, the length from the first bent portion 22 to the bottom surface of the hole 24 and the length from the lid-side first surface 31 to the lower end of the lid-side second surface 32 are set so that the first length and the third length are the same. However, this is not limited to this, and the length from the first bent portion 22 to the bottom surface of the hole 24 and the length from the lid-side first surface 31 to the lower end of the lid-side second surface 32 may be set so that the first length and the third length are different lengths.

[0053] Furthermore, in this embodiment, as shown in 3001, when the user lifts the lid 3, the upper part of the first main body surface 21 is opened. However, this is not limited to this, and the lid 3 may be held in a lifted state by a mechanism of the pivot shaft 33. For example, the pivot shaft 33 may be a member having elastic force such as a spring hinge, which may bias the lid 3 upward relative to the main body 2 and hold it in a lifted state. This can eliminate the need to lift the lid 3 at the start of the folding process. Furthermore, when the cover 3 is urged upward and lifted relative to the main body 2, the end of the cover 3 farther from the pivot shaft 33 may be closer to the pivot shaft 33 than the conductor end holder 24 in the direction parallel to the direction connecting the first bending portion 22 and the second bending portion 24. This allows for easy insertion of the conductor 5 into the conductor end holder 24 before the start of the bending process without getting in the way.

[0054] Furthermore, when the lid 3 is disposed in the opposing position, the opposing distance between the lid first surface 31 and the main body first surface 21 and the opposing distance between the lid second surface 32 and the main body side surface 25 may be adjustable. For example, the pivot shaft 33 may be configured to be movable in the vertical direction and / or in a direction parallel to the direction connecting the first bent portion 22 and the second bent portion 23 by a structural member such as a screw. This makes it possible to change the opposing distance depending on the outer diameter of the conductive wire 5. Furthermore, a return spring that biases the lid 3 to the raised state may be provided on the pivot shaft 33. In this way, after the user presses down on the lid 3 to bend the conductor 5, the lid 3 is returned to the raised state simply by releasing the user's hand, improving operability.

[0055] [Embodiment 2] Next, another embodiment of the present invention will be described below. For the sake of convenience, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0056] Fig. 4 is a side cross-sectional view showing a schematic configuration of the conductor bending jig 1 according to this embodiment. Fig. 5 is a plan view of the first main body surface 21 as viewed from above. As shown in these figures, the main body 2 has a main body movable part 27. The main body movable part 27 is movable in a direction parallel to the direction connecting the first bending part 22 and the second bending part 23. The main body movable part 27 is provided with a hole part 24 and the first bending part 22.

[0057] With this configuration, the positions of the hole 24 and the first bent portion 22 can be moved, and therefore the distance between the first bent portion 22 and the second bent portion 23 can be changed. Therefore, the second length of the conducting wire 5 can be changed in various ways.

[0058] In other words, the main body movable portion 27 can also be said to function as a second length adjustment member that moves the position of the hole portion 24 and the first bending portion 22 as the conductor end holding portion along the direction connecting the first bending portion 22 and the second bending portion 23.

[0059] The position of the main body movable part 27 is adjusted by the position adjustment part 45. The position adjustment part 45 has a screw part that extends in a direction parallel to the direction connecting the first bent part 22 and the second bent part 23. The screw part of the position adjustment part 45 is fitted into a female screw part that is provided in the main body movable part 27 and extends in a direction parallel to the direction connecting the first bent part 22 and the second bent part 23. The position of the main body movable part 27 is moved by rotating the position adjustment part 45 around its axis.

[0060] FIG. 6 is a cross-sectional view of the main body movable part 27, taken perpendicular to the direction connecting the first bending part 22 and the second bending part 23. As shown in the figure, sliders 46A and 46B are provided on two side surfaces parallel to the direction of movement of the main body movable part 27. The sliders 46A and 46B are cylindrical, and their axial directions are parallel to the direction of movement of the main body movable part 27. As the position adjustment part 45 rotates, the main body movable part 27 is guided by the sliders 46A and 46B, allowing it to move smoothly in a direction parallel to the direction connecting the first bending part 22 and the second bending part 23. The shape of the sliders 46A and 46B is not limited to a cylindrical shape, and any shape that can guide the linear movement of the main body movable part 27 may be used.

[0061] In the above configuration, a scale indicating the distance between the first bending portion 22 and the second bending portion 23 may be provided on the main body 2. For example, a distance indicator member indicating a distance scale in a state not linked to the movement of the main body movable portion 27 may be provided on the first main body surface 21, so that the distance between the first bending portion 22 and the second bending portion 23 can be visually confirmed.

[0062] Further, a groove laying member 41 having a groove 26 provided on its upper surface is provided on the main body movable part 27. The groove 26 provided on the upper surface of the groove laying member 41, the groove 26 provided on the upper surface of the main body movable part 27, and the groove 26 provided on the upper surface of the main body 2 in the vicinity of the second bent part 23 are all arranged in the same straight line.

[0063] The groove structuring member 41 is movable in a direction perpendicular to the first main body surface 21. The groove structuring member 41 also includes a biasing member 42 that biases the groove structuring member 41 in a direction that protrudes from a plane that includes the first main body surface 21.

[0064] 7 is a side view of groove maker 41 as viewed from a direction parallel to the direction connecting first bent portion 22 and second bent portion 23. As shown in the figure, groove 26 is provided on the upper surface of groove maker 41. Groove 26 on groove maker 41 is deeper and larger than groove 26 provided on the upper surface of main body movable portion 27 and groove 26 provided on the upper surface of main body 2 in the vicinity of second bent portion 23.

[0065] 8 is a diagram showing a state in which the lid-side first surfaces 31 are positioned opposite each other and the conductor 5 is sandwiched between the main body 2 and the lid 3, as viewed from a direction parallel to the direction connecting the first bent portion 22 and the second bent portion 23. The lid-side first surfaces 31 press down on the conductor 5 placed in the grooves 26 on the groove liner 41, thereby indirectly pressing down the groove liner 41. As a result, the conductor 5 is pressed against the grooves 26 provided on the upper surface of the main body movable part 27.

[0066] The underside of the lid 3 (the first lid surface 31) is provided with a space for accommodating the upper part of the groove laying member 41. As a result, in the state shown in Fig. 8, the first lid surface 31 does not directly press down on the groove laying member 41. On the other hand, the first lid surface 31 other than the space for accommodating the upper part of the groove laying member 41 presses down on the conducting wire 5.

[0067] According to the above configuration, when the cover 3 is placed in the opposing position, the groove maker 41 can be configured to sink appropriately into the inside of the main body 2 depending on the thickness of the conductor 5. Therefore, the size and depth of the groove 26 in the groove maker 41 can be increased to a certain extent, making it easier to guide the conductor 5 into the groove 26.

[0068] In this embodiment, the groove laying member 41 is provided on the main body movable part 27, but this is not limiting and it may be disposed on a line connecting the first bent part 22 and the second bent part 23. For example, the groove laying member 41 may be provided on a member constituting the main body 2 near the second bent part 23. Alternatively, the groove laying member 41 may be provided on the top surface of the main body 2 configured as shown in the first embodiment. (Example of a configuration equipped with a cutting member) Fig. 9 is a side cross-sectional view showing a configuration in which a cutting member 47 is provided in the conductor bending jig 1 according to this embodiment. Fig. 10 is a plan view of the main body first surface 21 as viewed from above. In the above-described first embodiment, as shown by 3004 in Fig. 3, the conductor 5 that protrudes downward from the lower end of the cover body second surface 32 and the lower end of the main body side surface 25 is cut by the user using any cutting means such as nippers. In contrast, in this embodiment, the conductor bending jig 1 is provided with the cutting member 47.

[0069] With the lid first surface 31 positioned opposite, the cutting member 47 cuts the conductor 5 protruding from the end in the extension direction of the lid second surface 32. Thus, the cutting member 47 can cut the portion of the bent conductor 5 protruding from the end in the extension direction of the lid second surface. Thus, the bent conductor can be cut and shaped into a predetermined shape such as a jumper wire.

[0070] Furthermore, cutting member 47 cuts conductor 5 at a position where the distance from second bending portion 23 is a predetermined third length. Here, third length is set to be equal to first length, which corresponds to the depth of hole 24. This makes it possible to produce conductor 5 having a shape in which the length from one end of conductor 5 to the point where it is bent by first bending portion 22 is equal to the length from the other end of conductor 5 to the point where it is bent by second bending portion 23.

[0071] The cutting member 47 is composed of an elastic surface member provided on the side surface of the main body 2. When the cutting member 47 is elastically deformed by the user, the conducting wire 5 protruding from the end in the extension direction of the lid-side second surface 32 is cut by a shear force generated between the cutting member 47 and the lower end of the main body-side surface 25. The cutting member 47 may also be provided on the lid 3 side.

[0072] The cutting member 47 and the lower end of the main body side surface 25 are preferably made of a metal material, but may be made of any material that can withstand the wear caused by cutting the conductor 5. The cutting member 47 is not limited to the above-described configuration, and may have any configuration that can cut the conductor 5 protruding from the end of the lid body second surface 32 in the extension direction at a predetermined position.

[0073] (Another configuration example of the main body movable part 27) FIG. 11 is a side cross-sectional view showing another example of the configuration of the main body movable part 27. As shown in the figure, the main body movable part 27 is provided with a hole unit insertion part 271, a hole unit fixing member insertion part 272, and a groove lining member insertion part 273. The hole unit insertion part 271 forms a wall surface of a space into which a hole unit 241 (described later) is inserted. The hole unit fixing member insertion part 272 forms a wall surface of the space into which a hole unit fixing member (not shown) is inserted. The hole unit fixing member fixes the hole unit 241 by pressing the hole unit 241 inserted into the hole unit insertion part 271 from the side. The hole unit fixing member may be formed, for example, by a screw, and may be configured to press the hole unit 241 from the side by engaging with a female thread formed in the hole unit insertion part 271. Pressing the hole unit 241 from the side by the hole unit fixing member prevents the hole unit 241 from slipping out of the hole unit insertion part 271.

[0074] The groove maker insertion section 273 forms the wall surface of the space into which the groove maker 41, which will be described later, is inserted. The groove maker insertion section 273 has a shape that penetrates the main body movable section 27 from the top surface to the bottom surface.

[0075] 12 shows an external perspective view of the hole unit 241 at 1201, and a cross-sectional view of the hole unit 241 at 1202. As shown in the figure, the hole unit 241 has a cylindrical shape in which the hole 24 is formed, and is composed of an upper cylindrical shape near the opening of the hole 24 and a lower cylindrical shape whose outer diameter is smaller than that of the upper cylindrical shape. The hole unit insertion portion 271 is formed in a shape that follows the outer diameter of the hole unit 241. When the hole unit 241 is inserted into the hole unit insertion portion 271, the insertion depth of the hole unit 241 is determined by the step at the boundary between the upper and lower cylindrical shapes of the hole unit 241.

[0076] As shown in 1202, the hole unit 241 has a structure in which the cylindrical inner wall surface in which the hole 24 is formed penetrates all the way to the bottom end. A cylindrical bottom member 242 that forms the bottom surface of the hole 24 is provided inside the cylindrical inner wall surface. A screw groove is formed on the cylindrical inner wall surface, and a screw groove is also formed on the cylindrical surface of the bottom member 242, so that the position of the bottom member 242 can be changed by rotating the bottom member 242. For example, a screw hole into which a screwdriver can be inserted may be formed on the lower surface of the bottom member 242, so that the position of the bottom member 242 can be changed by rotating the bottom member 242 from below with the screwdriver.

[0077] In this way, the hole unit 241 is configured to be able to change the depth of the hole 24. Therefore, the length from one end of the conductor 5 to the point where it is bent by the first bending unit 22 can be changed, making it possible to create conductors 5 bent in various shapes.

[0078] In addition, by preparing a plurality of types of hole units 241 each having a different inner diameter of hole 24 and changing the hole unit 241 to be used, the inner diameter of hole 24 can also be changed. This makes it possible to accommodate conductors 5 with various outer diameters.

[0079] FIG. 13 is a side view showing the configuration of the groove laying member 41 inserted into the groove laying member insertion section 273. As shown in the figure, the groove laying member 41 has a groove laying member fixing section 411 that passes through the center of the biasing member 42. The groove laying member fixing section 411 is connected to the groove laying member 41 with a screw. That is, when attaching the groove laying member 41 to the movable main body section 27, the groove laying member 41 and biasing member 42 are placed in the space above the groove laying member insertion section 273, and the groove laying member fixing section 411 is inserted from the space below the groove laying member insertion section 273. The groove laying member fixing section 411 is then rotated to fasten the groove laying member fixing section 411 and the groove laying member 41 with the screw. This allows for a simple and easy-to-install structure for attaching the groove laying member 41 to the movable main body section 27 in a vertically movable manner.

[0080] (Position adjustment of the main body side surface 25 and the lid side second surface 32) Next, a configuration example that allows the positions of the main body-side side surface 25 and the lid-side second surface 32 to be adjusted will be described. Fig. 14 is a side view showing the configuration of the main body 2 near the main body-side side surface 25 in this configuration example. As shown in the figure, the main body-side side surface 25 is made up of an upper main body-side side surface 251 and a lower main body-side side surface 252.

[0081] The upper main body side surface 251 is provided on the upper side surface holding portion 281, and the upper end portion of the upper main body side surface 251 forms the second folded portion 23. The upper side surface holding portion 281 is arranged in a fixed state on the side surface of the main body 2.

[0082] The lower main body-side side surface 252 is provided on a lower side surface holding portion 282. The lower side surface holding portion 282 is provided so as to be movable up and down while in contact with the side surface of the main body 2. Specifically, the lower side surface holding portion 282 is provided with a pair of holding portion sliders 283, and the holding portion sliders 283 slide in slider movement grooves 29 provided on the main body 2 so as to extend in the up and down direction, thereby allowing the lower side surface holding portion 282 to move up and down. This makes it possible to adjust the distance between the upper end of the upper main body-side side surface 251 and the lower end of the lower main body-side side surface 252, i.e., the distance from the second bent portion 23 to the lower end of the main body-side side surface 25.

[0083] 15 is a diagram showing the configuration of the upper side holding part 281, where 1501 is a front view as seen from the direction connecting the first bent part 22 and the second bent part 23, 1502 is a top view, and 1503 is a side view. As shown in 1501 and 1502, grooves 26 are provided on the upper surface of the upper side holding part 281. Also, in 1501, fixing holes 285 are provided on the left and right sides of the upper side holding part 281, and as shown in 1503, the fixing holes 285 penetrate all the way to the connection part with the main body 2. By inserting screws into these fixing holes 285, the upper side holding part 281 and the main body 2 can be connected in a fixed state.

[0084] 14, the upper surface of the upper side holding part 281 is located at a position that is higher than the upper surface of the main body 2 by a height that is approximately the depth of the groove part 26. This allows the conductive wire 5 placed in the groove part 26 of the upper side holding part 281 to be in contact with the upper surface of the main body 2, and the conductive wire 5 can be kept linear while being sandwiched between the first cover-side surface 31.

[0085] 16 is a diagram showing the configuration of the lower side holding part 282, with 1601 being a front view as seen from the direction connecting the first bent part 22 and the second bent part 23, 1602 being a top view, and 1603 being a side view. As shown in the figure, the lower side holding part 282 has a pair of slider insertion holes 286, 286 formed on its side. A holding part slider 283 is inserted into this slider insertion hole 286. Thread grooves are formed on the outer surface of the holding part slider 283 and on the inner surface of the slider insertion hole 286, and the holding part slider 283 is fixed to the lower side holding part 282 by screwing.

[0086] 17 shows the configuration of the lid body 3 in this configuration example, with 1701 being a side view and 1702 being a front view as seen from the direction connecting the first bent portion 22 and the second bent portion 23. As shown in the figure, the lid body 3 has a lid body side movable part 35 including a lid body side second surface 32. As shown in 1702, the lid body side movable part 35 is provided with lid body side movement grooves 351 extending in the vertical direction at positions on the left and right as seen from the direction perpendicular to the lid body side second surface 32. In addition, a lid body side slider 36 is provided that penetrates the lid body side movement groove 351 and connects the lid body side movable part 35 and the lid body 3.

[0087] The lid side slider 36 is screwed to the lid 3. When the screws connecting the lid side slider 36 to the lid 3 are loose, the lid side movable part 35 can move up and down relative to the lid 3, and the position of the lid side movable part 35 relative to the lid 3 is fixed by tightening the screws connecting the lid side slider 36 to the lid 3. This makes it possible to adjust the distance between the bottom end of the lid side second surface 32 and the plane including the lid side first surface 31.

[0088] In 1701, a retraction surface 311 is provided in the area of ​​the lid side first surface 31 near the lid side movable part 35, which forms a space capable of accommodating the vicinity of the upper surface of the upper side holding part 281 when the lid side first surface 31 is arranged in the opposing position. This makes it possible to prevent interference between the upper surface of the upper side holding part 281 and the lid side first surface 31 when the lid side first surface 31 is arranged in the opposing position.

[0089] As described above, according to this configuration example, it is possible to adjust the distance from second bending portion 23 to the lower end of main body side surface 25, and the distance between the lower end of lid body second surface 32 and the surface including lid body first surface 31. Therefore, it is possible to change the length from one end of conductive wire 5 to the point where it is bent by second bending portion 23, making it possible to create conductive wires 5 bent in various shapes.

[0090] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
