Description

[Technical field]

[0001] The present invention relates to a lead alignment jig. [Background technology]

[0002] Conventionally, a work process for manually attaching multiple lead wires to a product is known. Here, a worker can attach multiple lead wires to the product without excess or deficiency by considering a preparation process in which a predetermined number of lead wires (necessary for the product) are counted and prepared in advance, and an attachment process in which the prepared lead wires are attached to the product by soldering or the like.

[0003] A conventional method for preparing a predetermined number of lead wires 1 and attaching them to a product will be described with reference to Figures 15 and 16. Figure 15 is a diagram showing a bundle of lead wires. Figure 16 is a diagram showing the lead wires placed on a metal tray.

[0004] As shown in FIG. 15, a plurality of lead wires 1 are bundled together. The worker unties the bundle of lead wires 1U and takes out a predetermined number of lead wires 1 therefrom. Next, the worker spreads out the predetermined number of lead wires 1 on a metal tray T as shown in FIG. 16. In this way, the worker prepares a predetermined number of lead wires 1 (preparation process). Next, the worker takes out the lead wires 1 one by one from the spread out lead wires on the metal tray and attaches them to the product. The worker repeats this process to attach the predetermined number of lead wires 1 to the product (attachment process).

[0005] Meanwhile, Patent Document 1 discloses an automatic wire alignment machine that moves at least one of an alignment plate and a wire supply box by a driving means to store wires dropped from the wire supply box one by one in a groove of the alignment plate. Patent Document 2 discloses a cable alignment jig that has a plurality of grooves for holding cables, and has a portion inside the groove that has a width larger than the width of the groove opening.

[0006] [Patent Document 1] JP 2002-308413 A [Patent Document 2] JP 2020-124011 A Summary of the Invention [Problem to be solved by the invention]

[0007] When multiple lead wires are manually attached to a product, there is a problem that in the preparation process, it is time-consuming for the worker to count the required number of lead wires. In addition, if the worker makes a mistake in counting the lead wires in the preparation process, there is a problem that the worker may make a mistake in the number of lead wires to be attached in the attachment process, which may require rework on the product.

[0008] In particular, manually attaching a plurality of lead wires 1 to a product using the methods shown in Fig. 15 and Fig. 16 may be a burden for the worker. For example, if a worker has a disability in one hand, he or she must remove a predetermined number of lead wires 1 from the lead wire bundle 1U using only the other hand. Therefore, when removing the lead wires 1 from the lead wire bundle 1U and transferring them to a metal tray, there is a possibility that the lead wires 1 may be missed and dropped to the floor. Also, if a worker has an intellectual disability or a visual impairment, there is a possibility that the number of lead wires 1 may not be counted accurately.

[0009] The automatic wire alignment machine disclosed in Patent Document 1 is intended to be a device that automatically prepares wires, and does not take into consideration the smooth manual storage of lead wires in grooves. Even with the cable alignment tool disclosed in Patent Document 2, it is difficult to manually store cables smoothly in grooves. In the first place, lead wires are prone to breakage and need to be handled carefully, so there is also the problem that it is difficult to align lead wires using an alignment machine that automatically aligns wires as described above.

[0010] One aspect of the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a lead alignment jig that can properly prepare a predetermined number of lead wires. [Means for solving the problem]

[0011] In order to solve the above problems, a lead wire alignment jig according to one embodiment of the present invention is a lead wire alignment jig that slides a lead wire on the surface of a substrate, and includes a substrate having a plurality of linear grooves arranged side by side on its surface, each of the plurality of grooves having a storage section that stores one lead wire, and a guide contact section that is located on the opening side of the groove relative to the storage section and that contacts the lead wire while guiding the lead wire from the surface of the substrate to the storage section.

[0012] According to the above configuration, in the preparation process in which a worker manually prepares a predetermined number of lead wires, the worker can easily store one lead wire in the storage section by simply sliding the multiple lead wires on the surface of the substrate.

[0013] In addition, the guiding contact portion and part of the side surface of the first lead wire are designed to form a track that allows the second lead wire that has entered the groove to easily roll over the first lead wire. Therefore, the guiding contact portion can prevent the second lead wire from getting stuck in the groove.

[0014] In addition, the guide contact portion may be formed on one end side in the width direction of the groove portion, and a locking portion for preventing one of the lead wires stored in the storage portion from slipping out may be formed on the other end side in the width direction of the groove portion.

[0015] According to the above configuration, the worker can store the lead wire in the storage section by sliding the lead wire from one end side in the width direction of the groove to the other end side in the width direction of the groove. Therefore, the worker can easily align the lead wire by using the hand corresponding to the one end side. In addition, by providing a locking portion on the other end side of the lead wire, which is the movement direction, the possibility of the lead wire coming out of the storage section can be reduced.

[0016] In addition, in the width direction of the groove, a portion of the guide contact portion on the storage portion side and a portion of the guide contact portion on the front surface side of the substrate may be formed as a substantially flat surface.

[0017] According to the above configuration, a corner is formed between the guide contact portion and the storage portion, so that the worker can feel a clicking sensation when moving the lead wire to the storage portion.

[0018] In addition, at least a portion of the guide contact portion on the housing portion side in the width direction of the groove may be formed by a curved surface.

[0019] According to the above configuration, the lead wire that is guided to the storage section while in contact with the guide contact portion can be smoothly moved to the storage section. In addition, the worker can move the lead wire that has been moved to the storage section downward along the curved portion of the guide contact portion on the storage section side by simply sliding the lead wire from one end side to the other end side, and move the lead wire toward the one end side of the storage section. This makes it possible to prevent a situation in which the second lead wire gets stuck in the groove due to the first lead wire moving toward the other end side of the storage section.

[0020] The locking portion may be a side surface of the other end of the storage portion, and the height of the side surface of the other end may be greater than the height from the bottom surface of the storage portion to the center of gravity of one of the lead wires stored in the storage portion. The height of the side surface of the other end may be approximately the same as or greater than the wire diameter of the lead wire.

[0021] According to the above-mentioned configuration, it is possible to more reliably prevent the lead wires stored in the storage section from coming loose.

[0022] In addition, at least a portion of the guide contact portion on the housing portion side in the width direction of the groove may be concave.

[0023] According to the above configuration, when a second lead wire enters the groove in which a first lead wire is already housed, the second lead wire is urged upward by the portion of the guide contact part on the housing side, which makes it easier for the second lead wire to roll beyond the first lead wire.

[0024] In addition, at least a portion of the guide contact portion on the front surface side of the substrate in the width direction of the groove may be formed by a curved surface.

[0025] According to the above configuration, the lead wire sliding on the surface of the board can be smoothly moved to the guide contact portion.

[0026] The side surface of the other end of the storage portion may be concave in the depth direction of the groove portion.

[0027] According to the above-mentioned configuration, the side surface at the other end of the storage portion stops the lead wire from moving upward, thereby reducing the possibility that the lead wire will come loose from the storage portion.

[0028] Furthermore, at least a portion of a side surface of the other end of the storage section on an opening side of the groove may protrude toward the one end.

[0029] According to the above-mentioned configuration, at least a part of the upper end of the side surface on the other end side of the storage portion stops the lead wire from moving upward, thereby reducing the possibility that the lead wire will come loose from the storage portion.

[0030] The device may further include a depth adjustment portion for adjusting the depth of the groove portion.

[0031] In addition, the substrate may have a through hole penetrating from the rear surface of the substrate to the storage section, and the depth adjustment section may include a movable section that is movable in the depth direction of the groove section and is exposed in the storage section by inserting the through hole from the rear surface of the substrate, and an operating section that moves the movable section in the depth direction of the groove section when a predetermined operation is received from an operator.

[0032] According to the above configuration, the depth of the plurality of grooves can be changed by operating the operating part to move the movable part in the depth direction of the grooves, i.e., the depth of the plurality of grooves can be changed in accordance with the wire diameter of the lead wire.

[0033] In order to solve the above problems, a lead wire alignment jig according to one embodiment of the present invention is a lead wire alignment jig that includes a substrate having a plurality of linear grooves arranged side by side on its surface, and a lead wire is slid across the surface of the substrate to store and align one of the lead wires in each of the plurality of grooves, wherein the groove has a width and depth sufficient to store one of the lead wires, and includes a storage section for the lead wire, and a guide contact section that is located on the opening side of the groove relative to the storage section and that contacts the lead wire as the lead wire is slid across the surface of the substrate while guiding the lead wire from the surface of the substrate to the storage section, and wherein one of the slid lead wires is stored in the storage section by the guide contact section. Effect of the Invention

[0034] According to one aspect of the present invention, a predetermined number of lead wires can be appropriately prepared. [Brief description of the drawings]

[0036] 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 every respect. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In other words, in implementing the present invention, a specific configuration according to the embodiment may be appropriately adopted.

[0037] §1 Examples of application An example of a situation in which the lead wire alignment jig 100 is applied will be described with reference to Figures 1, 2 and 5. Figure 1 is a top view of the lead wire alignment jig 100 according to one embodiment of the present invention. Figure 2 is a diagram showing how the lead wires 1 are stored in the lead wire alignment jig 100. Figure 5 is an example of a cross-sectional view of a plurality of grooves 11 provided in the lead wire alignment jig 100.

[0038] As shown in FIG. 1, the lead wire alignment jig 100 includes a substrate 10 having a plurality of linear grooves 11 arranged side by side on a surface 10a. One end in the longitudinal direction of the grooves 11 is open on a side surface 10b of the substrate 10. As shown in FIG. 5, each of the grooves 11 includes a storage section 111 and a guide contact section 112. The storage section 111 stores one lead wire 1. The guide contact section 112 is located closer to the opening 11c of the groove 11 than the storage section 111, and when the lead wire 1 is slid by tracing it with the finger of an operator on the surface 10a of the substrate 10 as shown in FIG. 2, the guide contact section 112 contacts the lead wire 1 and guides the lead wire 1 from the surface 10a of the substrate 10 to the storage section 111.

[0039] According to this configuration, the guiding contact portion 112 allows one of the slid lead wires 1 to be smoothly dropped into the storage portion 111. Therefore, in a preparation step for preparing a predetermined number of lead wires 1, an operator can easily store one lead wire 1 in the storage portion 111 by simply sliding the multiple lead wires 1 on the front surface 10a of the substrate 10.

[0040] In addition, a track is designed by the guide contact portion 112 and a part of the side surface of the first lead wire so that the second lead wire 1B that has entered the groove can easily roll over the first lead wire 1A. Therefore, the guide contact portion 112 can prevent the second lead wire 1B from getting stuck in the groove portion 11.

[0041] In addition, the worker can quickly and properly prepare the specified number of lead wires 1 by visually confirming that the lead wires are stored in the same number of groove portions 11 as the specified number of lead wires 1.

[0042] Therefore, in the process of manually attaching the multiple lead wires 1 to the product, the lead wires are stored aligned in the multiple grooves, which reduces the labor of the worker to count the required number of lead wires. Also, the possibility of product loss due to miscounting the number of lead wires can be reduced.

[0043] Also, as shown in FIG. 2, a worker can store one lead wire 1 in the storage section 111 with one hand. Therefore, even if a worker has a disability in one hand, the worker can easily align a plurality of lead wires 1 with the other hand. Also, if a worker has an intellectual disability, the worker can visually check that the lead wires are stored in the same number of grooves 11 as the predetermined number of lead wires 1, thereby allowing the worker to properly prepare the predetermined number of lead wires 1. Also, if a worker has a visual disability, the worker can, for example, dig his / her fingernail into the grooves 11 to check that the lead wires 1 are stored in the grooves 11. That is, the range of people who can perform the work can be expanded.

[0044] In addition, one end of each of the grooves 11 in the length direction is open, so that one end of each of the lead wires 1 can be exposed from that end of the groove 11. Therefore, in the attachment process of attaching the prepared lead wires 1 to a product, a worker can easily take out the lead wires 1 one by one by grabbing and pulling the exposed portion 1a of the lead wire 1.

[0045] Furthermore, if a worker has a visual impairment, for example, by touching and tracing the exposed portions 1a of the lead wires 1 with a finger, the worker can check whether a predetermined number of lead wires 1 are inserted in the grooves 11. In particular, when storing the lead wires 1 in all the grooves 11, the worker can use his or her finger's sense of touch to check whether there are any grooves 11 from which a lead wire 1 has fallen out by touching and tracing the exposed portions 1a of the lead wires 1 with a finger.

[0046] §2 Configuration example (1. Schematic configuration of lead wire alignment jig 100) 1, the lead wire alignment jig 100 includes a substrate 10 having a surface 10a on which a plurality of linear grooves 11 are arranged side by side. The substrate 10 is, for example, a substantially rectangular member. In detail, the substrate 10 includes a first substrate portion 17 having a plurality of grooves 11 arranged side by side, and a flat substrate portion 18 located on an extension line of the plurality of grooves 11 in the longitudinal direction and having no grooves 11. In the following description, the side of the substrate 10 on which the plurality of grooves 11 arranged side by side is located is referred to as the front, the opposite side as the rear, the right side facing the front as the right side, and the left side as the left side.

[0047] The grooves 11 each extend in the front-rear direction. The grooves 11 are arranged in parallel at a predetermined pitch in the left-right direction. One end (front end) of the grooves 11 in the length direction (front-rear direction) is open at the side surface 10b of the substrate 10. That is, an opening 11a is formed at one end of the grooves 11 in the length direction. The other end (rear end) of the grooves 11 in the length direction is formed with an abutment surface 11b against which the other ends of the lead wires 1 abut.

[0048] The width and depth of the grooves 11 correspond to the wire diameter of the lead wires 1 so that one lead wire 1 is housed in each of the grooves 11. The length of the grooves 11 corresponds to the wire length of the lead wires 1 so that one end of the lead wire 1 is exposed at one end of the groove 11 (from the opening 11a) when the other end of the lead wire 1 abuts against the other end (abutment surface 11b) of the groove 11. The wire diameter of the lead wire 1 is typically about 1.5 mm. The wire length of the lead wire 1 is typically about 70 to 140 mm.

[0049] By using the lead wire alignment jig 100, an operator can quickly and appropriately prepare a predetermined number of lead wires 1. That is, first, the operator places the multiple lead wires 1 on the surface 10a of the substrate 10. Next, as shown in FIG. 2, the operator slides the multiple lead wires 1 on the surface 10a of the substrate 10. This allows the multiple lead wires 1 to be stored one by one in the multiple grooves 11, as shown in FIG. 1, and the multiple lead wires 1 can be aligned. Therefore, the operator can quickly and appropriately prepare a predetermined number of lead wires 1 by visually checking that the lead wires are stored in the same number of grooves 11 as the predetermined number of lead wires 1.

[0050] The lead wire alignment jig 100 further includes a cover member 30 that covers at least a portion of each of the grooves 11 on the surface 10a of the substrate 10 (see FIG. 4). The cover member 30 covers, for example, each of the grooves 11 from the other end (contact surface 11b) to just before one end (opening 11a), but does not cover the exposed portions 1a of the lead wires 1. With this configuration, the cover member 30 can prevent the lead wires 1, once housed, from coming out of the grooves 11. In addition, in the attachment process of attaching the prepared lead wires 1 to a product, a worker can easily take out the lead wires 1 one by one by grabbing and pulling the exposed portions 1a of the lead wires 1.

[0051] Moreover, the cover member 30 is, for example, a transparent plate-like member. This allows the worker to visually check the multiple grooves 11 even after the cover member 30 is placed on the surface 10a of the substrate. Here, for example, numbers assigned to each of the multiple grooves 11 may be written on the substrate 10 or the cover member 30 at positions corresponding to the multiple grooves 11. Alternatively, the positions corresponding to the multiple grooves 11 may be color-coded for each predetermined number (for example, the number of lead wires required for the product). This makes it easier for the worker to check the number of multiple grooves 11.

[0052] The cover member 30 is fixed at a predetermined position relative to the substrate 10. For example, the substrate 10 and the cover member 30 may each have a magnet at a corresponding position.

[0053] Fig. 3 is a rear perspective view of the lead wire alignment jig 100. Fig. 4 is a perspective view of the lead wire alignment jig 100 whose angle has been adjusted by the adjustment member 20. As shown in Fig. 3, the lead wire alignment jig 100 further includes an adjustment member 20 (installation angle adjustment section). The adjustment member 20 is, for example, a plate-shaped member made of acrylic.

[0054] A linear adjustment groove portion 13 extending in the left-right direction is formed in the front portion of the back surface 10c of the substrate 10. In the example shown in Fig. 3, three adjustment groove portions 13 are arranged side by side in the front-rear direction. The widths of the three adjustment groove portions 13 correspond to the adjustment members 20 so that the adjustment members 20 fit into the three adjustment groove portions 13.

[0055] As shown in FIG. 4, by inserting the adjustment member 20 into any one of the three adjustment grooves 13, the board 10 can be tilted at a predetermined angle with respect to the horizontal plane and installed on a workbench on which an operator works. That is, the adjustment member 20 adjusts the installation angle of the board 10 with respect to the horizontal plane so that one end of the multiple grooves 11 is higher than the other end. As a result, the lead wire 1 stored in the groove 11 is installed so that one end of the lead wire 1 is exposed obliquely upward through the opening 11a. Therefore, in the installation process, the operator can easily grasp the exposed portion 1a of the lead wire 1 exposed obliquely upward, and can easily take out the lead wire 1. In addition, when the board 10 is tilted, the abutting surface 11b of the groove 11 supports the lead wire 1. That is, the abutting surface 11b functions as a suppressing portion that suppresses the lead wire 1 from coming off the groove 11 when the board 10 is tilted. In addition, by installing the cover member 30 on the board 10, it is possible to further suppress the lead wire 1 from coming off the groove 11 when the board 10 is tilted. That is, the cover member 30 also functions as a suppression portion that suppresses the lead wire 1 from coming out of the groove portion 11 when the substrate 10 is tilted.

[0056] Furthermore, the installation angle of the board 10 can be adjusted by appropriately selecting the adjustment groove portion 13 into which the adjustment member 20 is inserted from among the three adjustment groove portions 13. This allows the lead wire alignment jig 100 to be installed at an installation angle desired by each worker. Note that the method for adjusting the installation angle of the board 10 is not limited to this, and for example, the installation angle of the board 10 may be adjusted by appropriately selecting a plurality of adjustment members 20 of different sizes. Furthermore, the lead wire alignment jig 100 may be installed at a predetermined installation angle by being supported by a member such as a clip, a magnet, or a spring.

[0057] (2. Configuration of Groove 11) FIG. 5 is a cross-sectional view of the groove 11 cut along a plane perpendicular to the length direction of the groove 11, and is an example of a cross-sectional view from the rear end to the front end of the lead alignment jig 100 (hereinafter referred to as a cross-sectional view of the groove 11). Hereinafter, one lead 1 housed in the groove 11 is referred to as a first lead 1A, and a lead 1 entering the groove 11 in which the first lead 1A has already been housed is referred to as a second lead 1B. Reference numeral 5001 in FIG. 5 indicates the trajectory of the first lead 1A when the first lead 1A is housed in the groove 11. Reference numeral 5002 in FIG. 5 indicates the trajectory of the second lead 1B when the second lead 1B entering the groove 11 rolls over the first lead 1A. A detailed configuration of the groove 11 will be described below with reference to FIG. 5.

[0058] As shown in Fig. 5, the groove 11 includes a storage portion 111 and a guide contact portion 112. The storage portion 111 stores one lead wire 1. The guide contact portion 112 is located closer to the opening 11c of the groove 11 than the storage portion 111, and when the lead wire 1 is slid on the front surface 10a of the substrate 10, the guide contact portion 112 contacts the lead wire 1 and guides the lead wire 1 from the front surface 10a of the substrate 10 to the storage portion 111. Of the slid lead wires 1, one lead wire 1 is stored in the storage portion 111 so as to fall therein (see reference numeral 5001 in Fig. 5).

[0059] With this configuration, in the preparation process in which a worker manually prepares a predetermined number of lead wires 1, the worker can easily store one lead wire 1 in the storage section 111 by simply sliding the multiple lead wires 1 with the fingers of one hand over the surface 10a of the substrate 10.

[0060] In addition, a track is designed by the guide contact portion 112 and a part of the side surface of the first lead wire 1A so that the second lead wire 1B that has entered the groove portion 11 can easily roll over the first lead wire 1A (see reference numeral 5002 in FIG. 5). Therefore, the guide contact portion 112 can prevent the second lead wire 1B from getting stuck in the groove portion 11.

[0061] In detail, a guide contact portion 112 is formed on one end side (right side) in the width direction (left-right direction) of the groove portion 11. Then, a locking portion that locks one lead wire 1 stored in the storage portion 111 from coming out is formed on the other end side (left side) in the width direction (left-right direction) of the groove portion 11. With this configuration, the worker can store the lead wire 1 in the storage portion 111 by sliding the lead wire 1 from right to left as seen from the worker with the fingers of the right hand. Therefore, the worker can easily align the lead wire 1 by using the right hand. The worker uses the lead wire alignment jig 100 by arranging it so that the first board portion 17 (see FIG. 1) is located further back than the second board portion 18 (see FIG. 1) as seen from the worker. Also, by providing the locking portion on the left side, which is the moving direction of the lead wire 1, the possibility of the lead wire 1 coming out of the storage portion 111 can be reduced.

[0062] The guide contact portion 112 includes, from the right side, a first guide contact portion 1121 and a second guide contact portion 1122. The first guide contact portion 1121 is a portion of the guide contact portion 112 on the front surface 10a side of the substrate 10. The second guide contact portion 1122 is a portion of the guide contact portion 112 on the storage portion 111 side. The first guide contact portion 1121 and the second guide contact portion 1122 are connected.

[0063] The second guide contact portion 1122 may be formed by a substantially flat surface in the width direction of the groove 11. In other words, the cross section of the second guide contact portion 1122 cut by a plane perpendicular to the length direction of the groove 11 may be a straight line. The second guide contact portion 1122 may include minute irregularities. The second guide contact portion 1122 may be formed by a substantially horizontal surface. Similarly, the first guide contact portion 1121 may be formed by a substantially flat surface in the width direction of the groove 11. The first guide contact portion 1121 may be formed so that the width of the groove 11 gradually increases toward the opening 11c of the groove 11. The first guide contact portion 1121 may be formed by an inclined surface that is inclined toward the front surface 10a side of the substrate 10. According to this configuration, an angle is formed between the guide contact portion 112 and the storage portion 111, so that the operator can feel a click when moving the lead wire 1 to the storage portion 111 (see reference numeral 5001 in FIG. 5).

[0064] The storage section 111 has a substantially rectangular cross section. That is, the storage section 111 is a space defined by a right side surface (right side surface 111a), a bottom surface 111b, and a left side surface (left side surface 111c). The bottom surface 111b is a substantially horizontal plane. The right side surface 111a and the left side surface 111c are planes that are substantially perpendicular to the bottom surface 111b. Note that the right side surface 111a and the left side surface 111c do not have to be perpendicular to the bottom surface 111b.

[0065] The storage section 111 has a locking portion that prevents one lead wire 1 stored in the storage section 111 from slipping out. In the example shown in Fig. 5, the locking portion is the left side surface 111c. Here, the left side surface 111c is higher than the right side surface 111a. With this configuration, it is possible to reduce the possibility that the lead wire 1 stored in the storage section 111 will slip out of the storage section 111, at least compared to a case in which the right side surface 111a and the left side surface 111c are at the same height.

[0066] 5, the height of the left side surface 111c is greater than the height from the bottom surface 111b of the storage section 111 to the center of gravity of the lead wire 1. Preferably, the height of the left side surface 111c is approximately the same as or greater than the wire diameter of the lead wire 1. When it is assumed that a plurality of lead wires 1 with different wire diameters will be stored in a plurality of grooves 11, the height of the left side surface 111c is designed for the lead wire 1 with the largest wire diameter. With this configuration, the lead wire 1 stored in the storage section 111 can be more reliably prevented from slipping out.

[0067] Preferably, the plurality of grooves 11 have the following dimensional ratios with respect to the wire diameter R of the lead wire 1. That is, the width d1 of the storage portion 111 is larger than the wire diameter R of the lead wire 1 and smaller than twice the wire diameter R. The width d2 of the opening 11c of the groove portion 11 is larger than the width d1 and is about 1.3 times (1.1 to 1.5 times) the wire diameter R of the lead wire 1. The depth h1 of the storage portion 111 is about 70% (60 to 80%) of the wire diameter R of the lead wire 1. The depth h2 of the guide contact portion 112 is about 40% (20 to 40%) of the wire diameter R of the lead wire 1. The inclination angle θ of the guide contact portion 112 is about 45° (40 to 50°). When it is assumed that a plurality of lead wires 1 with different wire diameters are stored in the plurality of grooves 11, the above dimensional ratios are designed with respect to the wire diameter R of the thinnest lead wire 1.

[0068] Because the width d1 of the storage section 111 is larger than the wire diameter R of the lead wire 1, when a worker stores the lead wire 1 in the groove section 11, the worker can smoothly drop the lead wire 1 into the storage section 111 by gravity without pushing the slid lead wire 1 from above. Also, because the width d1 of the storage section 111 is larger than the wire diameter R of the lead wire 1, a worker can easily take out the lead wires 1 one by one in the installation process.

[0069] 5, the guide contact portion 112 does not necessarily have to be provided on the left side. That is, the left side surface 111c is directly connected to the front surface 10a of the substrate 10. With this configuration, the lead wire 1 stored in the storage portion 111 can be more reliably prevented from coming loose.

[0070] Fig. 6 is another example of a cross-sectional view of the groove portion 11. Reference numeral 6001 in Fig. 6 indicates the trajectory of the first lead wire 1A when the first lead wire 1A is housed in the groove portion 11. Reference numeral 6002 in Fig. 6 indicates the trajectory of the second lead wire 1B when the second lead wire 1B, which has entered the groove portion 11, rolls over the first lead wire 1A. The example shown in Fig. 6 differs from the example shown in Fig. 5 in that a guide contact portion 112a is provided instead of the guide contact portion 112.

[0071] 6, the guide contact portion 112a includes, from the right side, a first guide contact portion 1121a, a second guide contact portion 1122a, and a third guide contact portion 1123a. The first guide contact portion 1121a is a portion of the guide contact portion 112b on the front surface 10a side of the substrate 10. The third guide contact portion 1123a is a portion of the guide contact portion 112a on the storage portion 111 side. The second guide contact portion 1122a is a portion that connects the first guide contact portion 1121a and the third guide contact portion 1123a.

[0072] The third guide contact portion 1123a may be formed by a curved surface in the width direction of the groove portion 11. In other words, the cross section of the third guide contact portion 1123a cut on a plane perpendicular to the length direction of the groove portion 11 may be curved. The third guide contact portion 1123a may be curved so as to be convex toward the opening 11c side (upper side) of the groove portion 11. The third guide contact portion 1123a may be smoothly connected to the storage portion 111. With this configuration, the lead wire 1 guided to the storage portion 111 while contacting the guide contact portion 112a can be moved smoothly to the storage portion 111 (see reference numeral 6001 in FIG. 6). In addition, the lead wire 1 moved to the storage portion 111 can be moved downward along the curved third guide contact portion 1123a by the operator simply sliding the lead wire 1 from the right side to the left side, and can be moved to the right side of the storage portion 111. Therefore, it is possible to prevent a situation in which the first lead wire 1A is shifted to the left side of the storage portion 111 and the second lead wire 1B is clogged in the groove portion 11 (see reference numeral 6002 in FIG. 6).

[0073] Similarly, the first guide contact portion 1121a may be formed by a curved surface in the width direction of the groove portion 11. The first guide contact portion 1121a may be curved so as to be convex toward the opening 11c side of the groove portion 11. The first guide contact portion 1121a may be smoothly connected to the surface 10a of the substrate 10. With this configuration, the lead wire 1 sliding on the surface 10a of the substrate 10 can be smoothly moved to the guide contact portion 112a.

[0074] Similarly, the second guide contact portion 1122a may be formed by a curved surface in the width direction of the groove portion 11. The second guide contact portion 1122a may be curved so as to be convex toward the opposite side (lower side) of the opening 11c of the groove portion 11. The second guide contact portion 1122a may have a shape corresponding to a part of the side surface of the lead wire 1 so that a part of the side surface of the lead wire 1 abuts against the second guide contact portion 1122a. For example, the curvature of the second guide contact portion 1122a may correspond to the curvature of the lead wire 1. Note that at least a part of the second guide contact portion 1122a abuts against a part of the side surface of the lead wire 1, and the remaining part of the second guide contact portion 1122a may not abut against a part of the side surface of the lead wire 1. The second guide contact portion 1122a may be smoothly connected to the first guide contact portion 1121a and the third guide contact portion 1123a.

[0075] Fig. 7 is yet another example of a cross-sectional view of the groove portion 11. Reference numeral 7001 in Fig. 7 indicates the trajectory of the first lead wire 1A when the first lead wire 1A is housed in the groove portion 11. Reference numeral 7002 in Fig. 7 indicates the trajectory of the second lead wire 1B when the second lead wire 1B, which has entered the groove portion 11, rolls over the first lead wire 1A. The example shown in Fig. 7 differs from the example shown in Fig. 5 in that a guide contact portion 112b is provided instead of the guide contact portion 112.

[0076] 7, the guide contact portion 112b includes, from the right side, a first guide contact portion 1121b, a second guide contact portion 1122b, and a third guide contact portion 1123b. The first guide contact portion 1121b is a portion of the guide contact portion 112b on the front surface 10a side of the substrate 10. The third guide contact portion 1123b is a portion of the guide contact portion 112b on the storage portion 111 side. The second guide contact portion 1122b is a portion that connects the first guide contact portion 1121b and the third guide contact portion 1123b.

[0077] The third guide contact portion 1123b may be formed by a substantially flat surface in the width direction of the groove 11. In other words, the cross section of the third guide contact portion 1123b cut along a plane perpendicular to the length direction of the groove 11 may be a straight line. The third guide contact portion 1123b may be formed by a substantially horizontal surface. The third guide contact portion 1123b may include minute irregularities. Similarly, the first guide contact portion 1121b may be formed by a substantially flat surface in the width direction of the groove 11. The first guide contact portion 1121b may be an inclined surface that is inclined toward the front surface 10a of the substrate 10. The second guide contact portion 1122b is similar to the second guide contact portion 1122a. According to this configuration, an angle is formed between the guide contact portion 112b and the storage portion 111, so that the operator can feel a click when moving the lead wire 1 to the storage portion 111 (see reference numeral 7001 in FIG. 7).

[0078] Fig. 8 is yet another example of a cross-sectional view of the groove portion 11. Reference numeral 8001 in Fig. 8 indicates the trajectory of the first lead wire 1A when the first lead wire 1A is housed in the groove portion 11. Reference numeral 8002 in Fig. 8 indicates the trajectory of the second lead wire 1B when the second lead wire 1B, which has entered the groove portion 11, rolls over the first lead wire 1A. The example shown in Fig. 8 differs from the example shown in Fig. 5 in that a guide contact portion 112c is provided instead of the guide contact portion 112.

[0079] The guide contact portion 112c includes, from the right side, a first guide contact portion 1121c and a second guide contact portion 1122c. The first guide contact portion 1121c is a portion of the guide contact portion 112c on the front surface 10a side of the substrate 10. The second guide contact portion 1122c is a portion of the guide contact portion 112c on the storage portion 111 side. The first guide contact portion 1121c and the second guide contact portion 1122c are connected.

[0080] The second guide contact portion 1122c may be concave in the width direction of the groove 11. In other words, the cross section of the second guide contact portion 1122c cut along a plane perpendicular to the length direction of the groove 11 may be concave. The first guide contact portion 1121c may be an inclined surface inclined toward the front surface 10a of the substrate 10. With this configuration, the second lead wire 1B that has entered the groove is urged upward by the second guide contact portion 1122c. This makes it easier for the second lead wire 1B to roll over the first lead wire 1A (see reference numeral 8002 in FIG. 8).

[0081] Fig. 9 is yet another example of a cross-sectional view of the groove 11. The example shown in Fig. 9 differs from the example shown in Fig. 6 in that the left side surface 111c is concave in the depth direction (vertical direction) of the groove 11. With this configuration, the left side surface 111c stops the upward movement of the lead wire 1. This reduces the possibility that the lead wire 1 will come out of the storage portion 111.

[0082] FIG. 10 is yet another example of a cross-sectional view of the groove 11. The example shown in FIG. 10 differs from the example shown in FIG. 6 in that at least a portion of the left side surface 111c on the opening 11c side (upper side) of the groove 11 protrudes toward the right. That is, the groove 11 further includes a protruding portion 113 protruding to the right at the upper end of the left side surface 111c. In the example shown in FIG. 10, the protruding portion 113 may have an inverted triangular cross-sectional shape so that it gradually protrudes to the right as it moves toward the upper side. According to this configuration, the protruding portion 113 stops the upward movement of the lead wire 1. Therefore, the possibility that the lead wire 1 will come out of the storage portion 111 can be reduced. The protruding portion 113 may have a rectangular cross-sectional shape.

[0083] The configuration of the groove 11 is not limited to the configuration shown in Figs. 5 to 10 above, and may be any configuration capable of storing one lead wire 1. For example, the bottom surface 111b of the storage section 111 may be concave (e.g., semi-elliptical). With such a configuration, the position in the left-right direction of the lead wire 1 stored in the storage section 111 is determined. Therefore, it is possible to prevent a situation in which the first lead wire 1A is shifted to the left side of the storage section 111 and the second lead wire is clogged in the groove 11.

[0084] Also, a guide contact portion may be formed not only on the right side but also on the left side. With such a configuration, when the second lead wire 1B enters the groove portion 11 in which the first lead wire 1A is already housed, the second lead wire 1B passing over the first lead wire 1A toward the left side can be guided to the surface 10a of the substrate 10 on the left side.

[0085] 5 to 10 may be formed at least only at the front and rear ends of groove portion 11. In addition, groove portions 11 may have grooves formed in locations other than the front and rear ends that are deeper than the grooves having the cross-sectional structures shown in FIGS.

[0086] Furthermore, the grooves 11 may have a structure obtained by laterally inverting the cross-sectional structure shown in Figures 5 to 10. With this configuration, the worker can store the lead wires 1 in the storage section 111 by sliding the lead wires 1 from the left side to the right side as seen by the worker. Therefore, the worker can easily align the lead wires 1 by using his / her left hand.

[0087] Also, the first substrate portion 17 (see FIG. 1) and the second substrate portion 18 (see FIG. 1) may be separate bodies. The second substrate portion 18 may be detachable from both the front end and the rear end of the first substrate portion 17. Here, when the second substrate portion 18 is provided at the rear end of the first substrate portion 17, the groove portion 11 has the cross-sectional structure shown in FIGS. 5 to 10. At this time, by providing the second substrate portion 18 at the rear end of the first substrate portion 17, the worker can store the lead wire 1 in the storage portion 111 by sliding the lead wire 1 from the right side to the left side as seen from the worker. Also, when the second substrate portion 18 is provided at the front end of the first substrate portion 17, the guide contact portions 112, 112a, 112b, and 112c are located on the left side of the second substrate portion 18 in the direction in which the first substrate portion 17 is located. Therefore, by providing second substrate portion 18 at the front end of first substrate portion 17, the worker can store lead wire 1 in storage portion 111 by sliding lead wire 1 from left to right as seen by the worker. In other words, by providing second substrate portion 18 at either the front end or the rear end of first substrate portion 17, one lead wire alignment jig 100 can provide a lead wire alignment jig for right-handed people and a lead wire alignment jig for left-handed people.

[0088] (3. Structure of Depth Adjustment Part 50) 11 and 12 are a side view and a top view of a lead wire alignment jig 100 including a width adjustment section 40 and a depth adjustment section 50. As shown in FIG. 11 and FIG. 12, the lead wire alignment jig 100 may include a width adjustment section 40 for adjusting the width of the plurality of grooves 11. In this case, the substrate 10 has a comb-tooth structure including a plurality of recesses (groove sections 11) extending in the front-rear direction on the front surface 10a and a plurality of protrusions 12 formed alternately with the plurality of recesses. The lead wire alignment jig 100 may also include a depth adjustment section 50 for adjusting the depth of the plurality of grooves 11. In this case, the substrate 10 includes a plurality of through holes 14 penetrating from the back surface 10c of the substrate 10 to the storage sections 111 of the plurality of grooves 11, respectively. The plurality of through holes 14 may extend in the length direction of the grooves 11. Note that detailed configurations of the grooves 11 are omitted from illustration in FIG. 11 and FIG. 12.

[0089] The width adjustment unit 40 includes a slide unit 41, a plurality of first movable units 42, and a plurality of adjustment cover units 43. The slide unit 41 is provided at the rear of the substrate 10, and slides in the left-right direction by the operation of the operator. Each of the plurality of first movable units 42 is arranged in parallel with the corresponding convex unit 12, and is connected to the slide unit 41. Each of the plurality of adjustment cover units 43 is a member that covers the gap between the corresponding convex unit 12 and the corresponding first movable unit 42, and is connected to the corresponding first movable unit 42. That is, the first movable unit 42 and the adjustment cover unit 43 move in the left-right direction in response to the sliding of the slide unit 41. The groove unit 11 is defined by the area between the convex unit 12 and the first movable unit 42 that is not covered by the adjustment cover unit 43.

[0090] According to this configuration, by sliding the slide portion 41 in the left-right direction, the first movable portion 42 can be moved in the left-right direction to change the width of the plurality of groove portions 11. In other words, the width of the plurality of groove portions 11 can be changed in accordance with the wire diameter of the lead wire 1.

[0091] The depth adjustment unit 50 includes an operation unit 51 and a plurality of second movable parts 52 (movable parts). The operation unit 51 is located below the back surface 10c of the substrate 10. The second movable parts 52 are inserted through corresponding through holes 14 from the back surface 10c of the substrate 10 and exposed in the storage unit 111. That is, the upper surface of the second movable parts 52 becomes the bottom surface 111b of the storage unit 111. The second movable parts 52 are connected to the operation unit 51 directly or via a link mechanism (see Figs. 13 and 14) described later. The second movable parts 52 are movable in the vertical direction. When the operation unit 51 receives a predetermined operation from an operator, it moves the second movable parts 52 in the vertical direction. The predetermined operation is a vertical slide when the second movable parts 52 are directly connected to the operation unit 51, and a horizontal slide when the second movable parts 52 are connected to the operation unit 51 via a link mechanism described later.

[0092] When the second movable parts 52 are directly connected to the operating part 51, the lead wire alignment jig 100 has a holding mechanism for holding the second movable parts 52 at desired positions in the vertical direction. Examples of the holding mechanism include a mechanism capable of adjusting the holding position by rotating a screw, or a mechanism capable of adjusting the holding position by having a claw portion engageable with a groove portion provided at a plurality of positions.

[0093] According to this configuration, by operating the operating part 51, the second movable part 52 can be moved in the vertical direction to change the depth of the plurality of grooves 11. In other words, the depth of the plurality of grooves 11 can be changed in accordance with the wire diameter of the lead wire 1.

[0094] As described above, by using the width adjustment unit 40 and the depth adjustment unit 50, the width and depth of the grooves 11 can be adjusted to correspond to the wire diameter of the lead wire 1. For example, when the lead wire 1A having the wire diameter R1 is to be stored in the grooves 11, the worker operates the slide unit 41 and the operation unit 51 as shown in FIG. 11 to make the width and depth of the grooves 11 correspond to the wire diameter R1. When the lead wire 1B having the wire diameter R2 (R2>R1) is to be stored in the grooves 11 instead of the lead wire 1A having the wire diameter R1, the worker operates the slide unit 41 and the operation unit 51 as shown in FIG. 12 to make the width and depth of the grooves 11 correspond to the wire diameter R2. Specifically, the worker slides the slide unit 41 to the right so as to move the first movable unit 42 to the right, and operates the operation unit 51 so as to move the second movable unit 52 downward. This allows the lead wire alignment jig 100 to correspond to the lead wires 1 having different wire diameters.

[0095] 13 and 14 are schematic diagrams showing an example of a link mechanism of depth adjustment unit 50. Depth adjustment unit 50 further includes a slider 53 and a plurality of link members 54 as a link mechanism that connects operation unit 51 and a plurality of second movable parts 52. The link mechanism will be described below with reference to FIGS. 13 and 14.

[0096] The slider 53 includes a first slider 531 and a plurality of second sliders 532. The first slider 531 is a slider extending in the left-right direction between the substrate 10 and the operation unit 51. The plurality of second sliders 532 are sliders extending upward from positions of the first slider 531 corresponding to the plurality of through holes 14, respectively.

[0097] Each of the multiple link members 54 includes a first slide joint 541, a second slide joint 542, and a drive link 543. The first slide joint 541 slides in the left-right direction on the first slider 531. The first slide joint 541 is fixed to the operation unit 51. The second slide joint 542 slides in the up-down direction on the corresponding second slider 532. The second slide joint 542 is fixed to the corresponding second movable unit 52. The drive link 543 connects the first slide joint 541 and the second slide joint 542.

[0098] According to this configuration, by sliding the operation unit 51 in the left-right direction, the second movable parts 52 can be moved in the up-down direction. For example, when the operation unit 51 is slid to the right from the state shown in Fig. 13, the first slide joint 541 fixed to the operation unit 51 also slides to the right on the first slider 531 as shown in Fig. 14. Therefore, the link member 54 tilts counterclockwise, and the second slide joint 542 slides downward on the second slider 532. Therefore, the second movable parts 52 fixed to the second slide joint 542 also move downward.

[0099] The operation unit 51 may be fixed to the first movable part 42 of the width adjustment unit 40. That is, the first movable part 42 may move left and right in conjunction with the left and right sliding of the operation unit 51. With this configuration, the first movable part 42 can move right (or left) at the same time as the second movable part 52 moves downward (or upward). Therefore, the width and depth of the multiple grooves 11 can be changed simultaneously in accordance with the wire diameter of the lead wire 1.

[0100] 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]
