[0028] [The problem this disclosure aims to solve]

[0029] The tray has a body-blocking member (equivalent to the support part in Patent Document 1) that contacts the body of the operator using the welding machine, thereby improving the stability of the tray during welding operations. However, when storing the tray in the storage box, the body-blocking member is sometimes too large to store easily. Therefore, it is desirable to develop a tray that can ensure stability during welding operations and can be easily stored in the storage box.

[0030] The purpose of this disclosure is to provide a welding operation tray that ensures stability during welding operations and can be easily stored in a storage box.

[0031] [The Effects of This Disclosure]

[0032] According to this disclosure, as one aspect, a welding operation tray can be provided that ensures stability during welding operations and can be easily stored in a storage box.

[0033] [Description of embodiments of this disclosure]

[0034] First, embodiments of the present disclosure will be described. One embodiment of the fusion splicing tray of the present disclosure is a tray used in optical fiber fusion splicing operations, comprising a tray body and a first body contact member. The tray body has: a pair of long wall portions, facing each other and extending along a first direction; and a pair of short wall portions, facing each other and extending along a second direction intersecting the first direction. In the tray body, a mounting portion for holding a fusion splicer is provided within a rectangular area defined by the pair of long wall portions and the pair of short wall portions. The first body contact member has an outer surface configured to contact the body of an operator using the fusion splicer, and the first body contact member is mounted to the tray body on one of the long wall portions. The first body contact member can transition between an unfolded state and a retracted state, wherein the unfolded state is a state in which the outer surface is unfolded along a third direction intersecting the first and second directions, and the retracted state is a state in which the first body contact member is retracted from the unfolded state.

[0035] The tray used for welding operations is equipped with a first body-blocking member that can switch between an unfolded state and a retracted state. Therefore, during welding operations, by unfolding the first body-blocking member, the operation can be performed while maintaining the stability of the tray. On the other hand, when storing the tray, by retracting the first body-blocking member, it can be easily stored in a storage box.

[0036] In one embodiment, the tray body may have a first region with a mounting portion and a second region on the opposite side of the first region in a third direction. Alternatively, a first body-blocking member may be connected to the tray body in the second region via a hinge mechanism. According to this embodiment, the first body-blocking member is located in the second region on the opposite side of the first region where the mounting portion for the welding machine is located. This allows the first body-blocking member to be stored along the second region without contacting the welding machine. Consequently, when storing the first body-blocking member, it is not necessary to remove the welding machine from the tray or move it from the mounting portion; it can be stored as is.

[0037] In one embodiment, the first body-blocking member may include: a main body portion that, in the unfolded state, extends along the edge of a long wall portion of the tray body to which the first body-blocking member is mounted in a first direction; and a pair of legs that extend in a third direction away from the tray body, with the two ends of the main body portion in the first direction as base ends. According to this embodiment, when the first body-blocking member is in a stowed state, other components (e.g., the second body-blocking member described later) can be stored in the space between the pair of legs, thereby improving storage efficiency.

[0038] In one implementation, the length of each pair of feet can be greater than the length of the tray body along a third direction. As the length of the feet increases, the outer surface of the first body contact member, which comes into contact with the operator's body using the welding machine, can be further expanded. According to this implementation, the outer surface of the first body contact member can be ensured to be large, thereby improving the stability of the tray during operation.

[0039] Alternatively, in the unfolded state, the width of the main body along a third direction may be less than half the length of each of the two legs. According to this embodiment, a large space between the two legs can be ensured, thereby further improving storage efficiency.

[0040] In one embodiment, the tray body may have a connecting portion for attaching a tripod that supports the tray. Alternatively, in the stowed state, the connecting portion may exist between a pair of legs when viewed from a third-party perspective. According to this embodiment, even with the first body-blocking member stowed, the tripod can be attached to the connecting portion of the tray body without obstructing the first body-blocking member.

[0041] In one embodiment, the outer surface of the first body contact member may include a curved surface that protrudes in a direction from the outside to the inside of the tray body. According to this embodiment, during welding operations, the outer surface of the first body contact member conforms to the operator's body, thereby improving the stability of the tray.

[0042] In one embodiment, a second body-blocking member may also be included. This second body-blocking member is detachably mounted to the tray body on one of the long wall portions of a pair of long wall portions and on the side opposite to the first body-blocking member. According to this embodiment, the tray not only has a first body-blocking member but also a second body-blocking member, thereby further improving the stability of the tray during welding operations. Furthermore, the second body-blocking member can be detached from the tray body, making it easy to store the tray in a storage box.

[0043] In one embodiment, the pallet body may have: a first mounting portion, located on one of a pair of long walls, for mounting a belt that wraps around the operator's waist; and a second mounting portion, located on both of a pair of short walls, for mounting a strap that wraps around the operator's neck. According to this embodiment, by securing the pallet body with the belt, the stability of the pallet during welding operations is improved. Furthermore, by hanging the strap attached to the pallet body around the neck, the operator can keep the pallet near their body while performing the operation even without continuously holding the pallet body with their hands. Therefore, the efficiency of the welding operation is improved.

[0044] Alternatively, at least one of the pair of long walls and the pair of short walls may have a slit recessed into the inside of the tray body. According to this embodiment, when the tray is stored in the storage box, devices respectively disposed in the space separated by the tray can be connected to each other via the slit with cables.

[0045] One embodiment of the welding machine kit disclosed herein includes: a storage box having a welding tray for welding operations as described in any of the above embodiments; and a welding machine mounted on the tray's mounting portion. In this welding machine kit, the welding tray for welding operations can be detached from the storage box. According to this welding machine kit, the same operational effects as those of the described embodiments of the welding tray for welding operations can be obtained.

[0046] [Details of the embodiments of this disclosure]

[0047] Hereinafter, one embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. The invention is not limited to these examples, but is illustrated by the claims, and is intended to include all modifications of the same meaning and scope. In the following description, the same reference numerals are used for the same elements or elements having the same function, and repeated descriptions are omitted.

[0048] Reference Figures 1 to 3 The storage box 1 and the welding machine kit 110 of one embodiment will be described. Figure 1 This is a perspective view of a storage box 1 according to one embodiment. Figure 2 This is a perspective view of the welding machine kit 110 of the storage box 1, including the lid 30 in the open state relative to the box body 10. Figure 3 This is a perspective view of the storage box 1, omitting the illustrations of various equipment such as the welding machine 100 stored inside. The following view shows the box with the lid 30 closed relative to the main body 10. Figure 1 In the state shown, the direction will be along the direction from the box body 10 toward the cover 30. Figure 1 The direction from top to bottom on the paper surface is called the thickness direction of storage box 1.

[0049] First, refer to Figure 2The fusion splicer 100, housed in the storage box 1, will be described. The fusion splicer 100 is a device for splicing optical fibers together. A cover 101 and a heater 102 are provided on the upper part of the fusion splicer 100. The cover 101 is fitted to freely open and close cover the heat-bonding section (not shown) used for thermally bonding the optical fibers together, thereby preventing airflow into the heat-bonding section. The heater 102 is used to heat and shrink the fiber reinforcement sleeve covering the fusion portion of the optical fibers that have been thermally bonded through the heat-bonding section. Furthermore, the fusion splicer 100 includes a monitor 103, which displays the fusion status of the optical fibers as captured by a camera (not shown) located inside. In the fusion splicer kit 110, the fusion splicer 100, other splicing tools, and spare parts are stored in the storage box 1.

[0050] Storage box 1 is a box for storing the fusion splicer 100 for optical fibers. Storage box 1 includes a main body 10, a cover 30, and a tray 40. (The text abruptly ends here.) Figure 2 As shown, the lid 30 is fitted to the box body 10 via a hinge 2 in a manner that allows it to be opened / closed relative to the box body 10. The storage box 1 has a hinge 2, thereby allowing it to be opened / closed from... Figure 1 The state of the closed cover 30 shown is transitioned to Figure 2 The diagram shows the open state of the lid 30. It is also possible to transition from the open state to the closed state. In this embodiment, the lid 30 is configured to open approximately 180° relative to the main body 10, but the angle at which the lid 30 can be opened is not limited. For example, the lid 30 may also be configured to open 90° relative to the main body 10. Furthermore, the lid 30 may be detachable from the storage box 1.

[0051] The storage box 1 has a ring-shaped handle 3. The handle 3 is mounted on the side of the box body 10 opposite to the side where the hinge 2 is located. The operator can easily carry the storage box 1 by holding the handle 3. The handle 3 can also be provided on the lid 30. The storage box 1 has a pair of locking members 4. Each locking member 4 is composed of a pair of fittings respectively provided on the box body 10 and the lid 30. The lid 30 is kept closed by the pair of fittings engaging with each other, thereby preventing accidental opening or closing of the lid 30.

[0052] like Figure 1As shown, the storage box 1 includes a insertion part 5, which is configured to allow a cable extending from the inside of the storage box 1 to be inserted when the cover 30 is closed relative to the box body 10. The cable may be, for example, a power cable used to power the fusion splicer 100. If the cable is a power cable, one end is connected to the fusion splicer 100, and the other end is connected to an external power source. Detailed configuration of the insertion part 5 will be described later. In the following description, the side where the handle 3 is located is designated as the front side of the storage box 1, and the side where the hinge 2 is located is designated as the rear side. Furthermore, in the thickness direction of the storage box 1, the side where the cover 30 is located is designated as the upper side of the storage box 1, and the side where the box body 10 is located is designated as the lower side.

[0053] like Figure 3 As shown, the box body 10 is a box-shaped member with an opening at the top and a bottom. The box body 10 has a bottom plate 11 and a first peripheral wall 12 (first side wall). The bottom plate 11 is a plate-shaped member that is generally rectangular when viewed from above, and is located at the bottom of the box body 10. The inner surface of the bottom plate 11 is provided with a protrusion 11a for use in the organization of equipment, etc., stored in the box body 10. The inner surface of the bottom plate 11 can be a flat surface without the protrusion 11a, or it can be provided with a partition plate with a height greater than the protrusion 11a.

[0054] The first peripheral wall 12 is a wall-like member that rises from the edge of the base plate 11. The first peripheral wall 12 includes: a front peripheral wall 12a with a handle 3; a rear peripheral wall 12b located opposite to the front peripheral wall 12a and equipped with a hinge 2; and a left peripheral wall 12c and a right peripheral wall 12d connecting the front peripheral wall 12a and the rear peripheral wall 12b, respectively. The left peripheral wall 12c is a wall-like member located on the left side of the box body 10 when viewed from the front peripheral wall 12a, and the right peripheral wall 12d is a wall-like member located on the right side of the box body 10. The widths of the front peripheral wall 12a and the rear peripheral wall 12b are slightly larger than the widths of the left peripheral wall 12c and the right peripheral wall 12d. Therefore, the overall shape of the box body 10 is such that its width in the left-right direction is greater than its width in the front-back direction. The shape of the box body 10 is not limited; it can also be a shape where the width in the front-back direction is equal to the width in the left-right direction.

[0055] The base plate 11 and the first peripheral wall 12 can be formed of resins such as polypropylene or polyethylene. The lower portions of the base plate 11 and the first peripheral wall 12 are constructed by laminating components made of the same or different materials, and their thickness is greater than that of the upper portion of the first peripheral wall 12. This allows for more reliable protection of the welding machine 100 from impacts applied to the lower part of the storage box 1 should it fall. Furthermore, a stepped surface 20 is provided at the boundary between the upper and lower portions of the first peripheral wall 12 due to the difference in thickness. The stepped surface 20 is continuously provided along the inner periphery of the first peripheral wall 12. (Tray 40 - see reference) Figure 2The edge of the ) is placed on the step surface 20.

[0056] The cover 30 is a component that blocks the opening of the main body 10 of the box, and has a top plate 31 and a second peripheral wall 32 (second side wall). The top plate 31 is a plate-like component that is roughly rectangular in shape when viewed from above, and is located on the upper part of the cover 30. Figure 2 As shown, the inner surface of the top plate 31 has a protrusion 31a that matches the shape of the welding machine 100. When the cover 30 is closed, the protrusion 31a covers the upper part of the welding machine 100. This prevents the welding machine 100 from shifting position during transport of the storage box 1. The top plate 31 may also be a flat surface without the protrusion 31a.

[0057] The second peripheral wall 32 is a wall-like member that rises from the edge of the top plate 31. The second peripheral wall 32 has a front peripheral wall 32a, a rear peripheral wall 32b, a left peripheral wall 32c, and a right peripheral wall 32d. When the lid 30 is closed, the front peripheral wall 32a is a wall-like member located at the front of the storage box 1, and the rear peripheral wall 32b is a wall-like member located at the rear of the storage box 1. In addition, the left peripheral wall 32c is a wall-like member located on the left side of the storage box 1, and the right peripheral wall 32d is a wall-like member located on the right side of the storage box 1. The widths of the front peripheral wall 32a, the rear peripheral wall 32b, the left peripheral wall 32c, and the right peripheral wall 32d are designed to be approximately the same as the widths of the front peripheral wall 12a, the rear peripheral wall 12b, the left peripheral wall 12c, and the right peripheral wall 12d of the main body 10.

[0058] The top plate 31 and the second peripheral wall 32 can be formed of resins such as polypropylene or polyethylene. The top plate 31 and the second peripheral wall 32 are constructed by laminating components made of the same or different materials, and are made thicker than the upper part of the first peripheral wall 12 of the main body 10. As a result, the welding machine 100 stored inside the storage box 1 can be more reliably protected from external impacts.

[0059] The top plate 31 or the second peripheral wall 32 has a window W formed by a transparent member that transmits visible light. The window W can also be formed, for example, by inserting a transparent resin member into an opening formed in the top plate 31 or the second peripheral wall 32. The window W can be located in a position where the charging status of the welding machine 100 can be visually identified. For example, if the lamp indicating the charging status is located on the right side of the welding machine 100, the window W can also be located on the portion of the top plate 31 near the right peripheral wall 32d or on the right peripheral wall 32d itself. In this embodiment, the window W is located on the right peripheral wall 32d of the second peripheral wall 32. The window W is not limited to being located on the cover 30, but can also be located on the first peripheral wall 12 of the main body 10.

[0060] like Figure 2As shown, the first peripheral wall 12 of the box body 10 has a first edge 13, and the second peripheral wall 32 of the cover 30 has a second edge 33. When the cover 30 is closed relative to the box body 10, the first edge 13 and the second edge 33 are in contact with each other. The first edge 13 has an annular shape that extends continuously along the upper end of the first peripheral wall 12. The second edge 33, like the first edge 13, has an annular shape that extends continuously along the lower end of the second peripheral wall 32. The portions of the first edge 13 and the second edge 33 in which the locking member 4 is fitted are recessed inward toward the box body 10. When the cover 30 is closed, as... Figure 1 As shown, the first edge 13 extends to the entire circumference of the annular shape and contacts the second edge 33. This prevents water droplets, dust, and other particles from entering the storage box 1 through the gap between the box body 10 and the lid 30.

[0061] As described above, the storage box 1 has a insertion part 5 (see reference). Figure 1 The insertion part 5 allows cables extending from the inside of the housing body 10 to be inserted when the cover 30 is closed. The insertion part 5 has cutouts 18 and 38 (see reference 18) respectively provided by the first edge 13 and the second edge 33. Figure 4 , Figure 6 The box is constructed with cuts 18 and 38. Cut 18 forms the first box cut, and cut 38 forms the second box cut. Cut 18 is located at the first edge 13 of the right peripheral wall 12d, and cut 38 is located at the second edge 33 of the right peripheral wall 32d. When the cover 30 is closed, at least a portion of cut 18 coincides with cut 38 in the thickness direction of the first peripheral wall 12 and the second peripheral wall 32. It should be noted that in cuts 18 and 38, the first edge 13 does not contact the second edge 33 to form an opening.

[0062] Reference Figures 4 to 7 The detailed composition of incisions 18 and 38 is explained. Figure 4 and Figure 5 yes Figure 2 The enlarged view shown is of region A, enclosed by a dashed line, which is part of the main body 10 of the box (the part with the cutout 18 in the first edge 13). For ease of explanation, in... Figure 4 The illustration of sealing member 19 is omitted. Figure 5 The middle figure shows sealing component 19. Figure 6 and Figure 7 yes Figure 2 The enlarged view shown is of region B, enclosed by a dashed line, which is part of the cover 30 (the portion with the cutout 38 in the second edge 33). For clarity, in... Figure 6 The illustration of sealing member 39 is omitted. Figure 7 The middle figure shows the sealing component 39.

[0063] like Figure 4 As shown, the first edge 13 has an end face 14 (first end face) and a first thin wall 15. The end face 14 is a flat surface provided along the first edge 13. The first thin wall 15 is a wall-like member erected relative to the end face 14, and most of it is provided along the first edge 13. The first thin wall 15 has a recessed portion 15A in a portion that is recessed toward the inside of the box body 10. The recessed portion 15A is configured to include a pair of transverse wall portions 16 (first transverse wall portions) and an inner wall portion 17. Each transverse wall portion 16 extends toward the inside of the box body 10 in a direction that intersects (orthogonal in this embodiment) the extending direction of the first edge 13. The pair of transverse wall portions 16 are arranged opposite each other. Each transverse wall portion 16 has an upper surface 16a at its respective upper end. The height of each transverse wall portion 16 (the distance from the end face 14 to the upper surface 16a) is the same as the height of the portion of the first thin wall 15 where no recess 15A is provided (hereinafter referred to as the non-recessed portion).

[0064] The inner wall portion 17 is located closer to the inner side of the housing body 10 than the non-recessed portion of the first thin wall 15. The inner wall portion 17 is provided along the opposing direction of the pair of transverse wall portions 16, i.e., the extending direction of the first edge portion 13, and its two ends are connected to the ends of the transverse wall portions 16. The inner wall portion 17 has an upper surface 17a at its upper end. A cutout 18 is provided in the central portion of the inner wall portion 17. The cutout 18 is a portion through which a cable extending from the inside to the outside of the housing body 10 is inserted. The cutout 18 is U-shaped and has a smoothly curved bottom surface 18a. Furthermore, the connection between the end of the cutout 18 and the upper surface 17a is smoothly made by beveling. Therefore, when a cable is placed in the cutout 18, even if the cable comes into contact with the aforementioned connection portion, the cable sheath is less likely to be damaged. The width of the cutout 18 along the extending direction of the inner wall portion 17 is configured to gradually decrease from the upper surface 17a side towards the end face 14 side. The shape of the cut 18 is not limited to the shape described above; for example, it can also be formed as a V-shape with a pointed bottom.

[0065] Compared to the two ends of the inner wall portion 17 that connect to the transverse wall portion 16, the portion near the cutout 18 is configured to have a greater height (distance from the end face 14 to the upper surface 17a). This prevents cables inserted into the cutout 18 from slipping outwards. Furthermore, the inner wall portion 17 is configured such that its thickness decreases from the end face 14 side towards the upper surface 17a side.

[0066] like Figure 5 As shown, a sealing member 19 (first sealing member) is disposed on the end face 14. The sealing member 19 and the sealing member 39 (see reference) of the cover body 30... Figure 7The sealing members 18 and 38 together seal the gap between the cuts 18 and 38 and the cables inserted through them. The sealing member 19 is formed of an elastic material. The material of the sealing member 19 may be, for example, silicone rubber, TPE (Thermoplastic Elastomer), or a microcell polymer sheet. The hardness of the sealing member 19 is preferably 20 or higher and 40 or lower, more preferably 30. The hardness of the sealing member 19 is a value measured based on JIS standard K6253.

[0067] The sealing member 19 is formed in a cuboid shape and is configured such that its longitudinal direction extends along the direction of the first edge 13. The sealing member 19 has a pair of end faces 19a facing each other in the longitudinal direction. In this embodiment, each end face 19a is located slightly away from the wall surface of the transverse wall portion 16. Due to these gaps, the sealing member 19 is easily deformed when a cable is inserted. It should be noted that each end face 19a may contact the wall surface of the transverse wall portion 16 as long as it does not obstruct the retention of the cable passing through the sealing member 19. The sealing member 19 has four sides that connect the pair of end faces 19a to each other. The side that contacts the end face 14 (not shown) is designated as the lower side, and the side facing the lower side is designated as the upper side 19b. Furthermore, the side connecting the lower side and the upper side 19b is designated as the outer side 19c and the inner side 19d. The outer side 19c and the inner side 19d face each other. The outer side 19c is located on the outer side of the housing body 10 compared to the inner side 19d.

[0068] The lower side is bonded to the end face 14 using an adhesive. Thus, the sealing member 19 is fixed to the first edge 13. The method of fixing the sealing member 19 is not limited. For example, if the end face 14 has a protrusion, the sealing member 19 can be fixed by having the protrusion engage with the lower side. The upper side 19b is located further away from the end face 14 than the upper surface 16a. That is, the thickness of the sealing member 19 (the width from the lower side to the upper side 19b) is greater than the height of the transverse wall portion 16. Furthermore, the upper side 19b is located further away from the bottom surface 18a of the cutout 18 (see reference). Figure 4 The sealing member 19 is located away from the end face 14. That is, when the sealing member 19 is visually identified from the outer side 19c, at least a portion of the sealing member 19 overlaps with the cutout 18. Thus, when the cable is inserted into the cutout 18, the cable is configured to slightly recess into the interior of the sealing member 19.

[0069] The outer surface 19c is located on the outer side of the box body 10, relative to the non-recessed portion of the first thin wall 15. Alternatively, the outer surface 19c may be located on the inner side of the box body 10, relative to the non-recessed portion of the first thin wall 15, i.e., within the recessed portion 15A of the first thin wall 15. The inner surface 19d is located slightly away from the wall surface of the inner wall portion 17. Alternatively, the inner surface 19d may be located in contact with the wall surface of the inner wall portion 17. The shape of the sealing member 19 is not limited to the shapes described above. The sealing member 19 may, for example, be cubic. Furthermore, a groove may be provided on the upper surface 19b of the sealing member 19, extending along the direction connecting the outer surface 19c and the inner surface 19d, and a cable may be disposed in this groove.

[0070] like Figure 6 As shown, the second edge 33 has an end face 34 (second end face) and a second thin wall 35. The end face 34 is a flat surface provided along the second edge 33. The second thin wall 35 is a wall-like member erected relative to the end face 34, and most of it is provided along the second edge 33. The second thin wall 35 has a pair of transverse wall portions 36 (second transverse wall portions) and an outer wall portion 37. Each transverse wall portion 36 extends toward the inside of the cover 30 in a direction that intersects (orthogonally in this embodiment) the extending direction of the second edge 33. The pair of transverse wall portions 36 are provided opposite to each other. Each transverse wall portion 36 has an upper surface 36a at its respective upper end. The height of each transverse wall portion 36 (the distance from the end face 34 to the upper surface 36a) is the same as the height of the portion of the second thin wall 35 extending along the second edge 33 (the distance from the end face 34 to the upper surface 35a). The outer wall portion 37 is provided along the second edge 33.

[0071] A cutout 38 is provided in the portion of the outer wall portion 37 corresponding to the area between the pair of transverse wall portions 36 (the portion of the outer wall portion 37 located between the pair of transverse wall portions 36). The cutout 38 allows a cable extending from the inside of the housing body 10 to the outside to pass through. The cutout 38 is formed in a U-shape and has a smoothly curved bottom surface 38a. Furthermore, the end of the cutout 38 is smoothly connected to the upper surface 35a by means of a chamfer. As a result, when a cable is placed in the cutout 38, even if the cable comes into contact with the aforementioned connection portion, the cable sheath is not easily damaged. The width of the cutout 38 along the extending direction of the second edge portion 33 is configured to gradually decrease from the upper surface 35a toward the end face 34. The shape of the cutout 38 is not limited to the shape described above; for example, it may also be formed as a V-shape with a pointed bottom.

[0072] like Figure 7 As shown, a sealing member 39 (second sealing member) is disposed on the end face 34. The sealing member 39 and the sealing member 19 (see reference) of the housing body 10 are also present. Figure 5Commonly, when the cover 30 is closed relative to the housing body 10, the gap between the cutouts 18 and 38 and the cable inserted through the cutouts 18 and 38 is sealed. The sealing member 39, like the sealing member 19 described above, is formed of an elastic material. The material of the sealing member 39 can be, for example, silicone rubber, TPE (Thermoplastic Elastomer), or a microporous polymer sheet. The hardness of the sealing member 39 is preferably 20 or higher and 40 or lower, more preferably 30. The hardness of the sealing member 39 is measured based on the same standard as the hardness measurement of the sealing member 19 described above.

[0073] The sealing member 39 is formed in a cuboid shape and is configured such that its longitudinal direction extends along the direction of the second edge 33. The sealing member 39 has a pair of end faces 39a facing each other in the longitudinal direction. In this embodiment, each end face 39a is slightly separated from the wall surface of the transverse wall portion 36, but may also contact the wall surface of the transverse wall portion 36. The sealing member 39 has four side faces that connect the pair of end faces 39a to each other. The four side faces are connected to the end face 34 (see reference 34). Figure 6 The contact surface (not shown) is designated as the lower side surface, and the surface opposite to the lower side surface is designated as the upper side surface 39b. Furthermore, the side surface connecting the lower side surface and the upper side surface 39b is designated as the outer side surface 39c and the inner side surface 39d. The outer side surface 39c and the inner side surface 39d are opposite to each other. The outer side surface 39c is located on the outer side of the cover 30 compared to the inner side surface 39d.

[0074] The lower side of the sealing member 39 is bonded to the end face 34 using an adhesive. Thus, the sealing member 39 is fixed to the second edge 33. The method of fixing the sealing member 39 is not limited. For example, if the end face 34 has a protrusion, the sealing member 39 can be fixed by biting the protrusion into the lower side. The upper side 39b is located further away from the end face 34 than the upper surface 36a. That is, the thickness of the sealing member 39 (the width from the lower side to the upper side 39b) is greater than the height of the transverse wall portion 36. Furthermore, the upper side 39b is located further away from the end face 34 than the bottom surface 38a of the cutout 38. That is, when the sealing member 39 is visually identified from the inner side 39d, at least a portion of the sealing member 39 overlaps with the cutout 38. When a cable is inserted into the cutout 38, the cable is configured to slightly recess into the interior of the sealing member 39.

[0075] The outer surface 39c is located slightly away from the wall surface of the opposing second thin wall 35. Alternatively, the outer surface 39c may be located in contact with this wall surface. The inner surface 39d is located inside the cover 30, beyond the ends of each transverse wall portion 36. Alternatively, the inner surface 39d may be located outside the cover 30, beyond the ends of each transverse wall portion 36, i.e., within the area sandwiched between the pair of transverse wall portions 36. The shape of the sealing member 39 is not limited to the shape described above. The sealing member 39 may, for example, be cubic. Furthermore, the upper surface 39b of the sealing member 39 may have a groove extending along the direction connecting the outer surface 39c and the inner surface 39d, in which a cable is disposed.

[0076] Figure 8 This diagram shows the state in which cable C is clamped by sealing member 19 and sealing member 39. Figure 8 For ease of explanation, illustrations of the components of the cover 30 other than the sealing member 39 are omitted. The cable C may be a power supply cable used to power the fusion splicer 100. When the cover 30 is closed with the cable C inserted into the cut 18 of the housing body 10, as shown... Figure 8 As shown, sealing member 19 and sealing member 39 are in contact such that they coincide in the thickness direction of the housing body 10. Specifically, the upper side 19b of sealing member 19 (refer to...) Figure 5 ) and the upper side 39b of the sealing member 39 (refer to Figure 7 ) contact. With the cover 30 closed, the second thin wall 35 of the cover 30 (refer to Figure 7 The first thin wall 15 and sealing members 19 and 39 are located on the outer side of the storage box 1, relative to the main body 10. That is, from the inside of the storage box 1 to the outside, the cutout 18, sealing member 19, sealing member 39, and cutout 38 are arranged in sequence. The outer side of the second thin wall 35 becomes the outermost circumferential surface of the first peripheral wall 12 and the second peripheral wall 32.

[0077] Cable C is held between sealing member 19 and sealing member 39. Sealing member 19 and sealing member 39 are formed of an elastic material as described above. Therefore, sealing member 19 and sealing member 39 deform to match the shape of cable C and seal tightly against the cable C. Cable C extends from the inside of the housing 1 through the cut 18, between sealing member 19 and sealing member 39, and through the cut 38 to the outside of the housing 1. As described above, cable C can be a power cable used to power the fusion splicer 100, or a power cable used to power an information terminal (e.g., a smartphone) used to manage the fusion splicing operation of the fusion splicer 100. Two or more cables C may be held between sealing member 19 and sealing member 39.

[0078] Reference Figures 9 to 11The composition of tray 40 will be explained. Figure 9 This is a three-dimensional view of the tray 40 when visually recognizing it from the first area 50 side. Figure 10 This is a three-dimensional view of the tray 40 when visually recognizing it from the second area 60 side. Figure 11 It is along Figure 2 The cross-sectional view shown is taken when the storage box 1 is cut along line XI-XI. Figure 11 For ease of explanation, illustrations of various devices and the cover 30 stored in the main body 10 of the box, excluding the tray 40, are omitted. In the following description, when the tray 40 is stored in the main body 10 of the box (refer to...),... Figure 2 The tray 40 has a tray body 41, a first body-blocking member 70, and a second body-blocking member 80. The side facing the front peripheral wall 12a of the main body 10 is designated as the front side of the tray 40, the side facing the rear peripheral wall 12b is designated as the rear side of the tray 40, the side facing the left peripheral wall 12c is designated as the left side of the tray 40, and the side facing the right peripheral wall 12d is designated as the right side of the tray 40.

[0079] The tray body 41 is a worktable used for fusion splicing operations, where the fusion splicer 100 and the like are organized and stored in the storage box 1. The operator holds the tray body 41 in front of their body (e.g., their abdomen) and performs the fusion splicing operation on it. A pair of long wall portions 42 and a pair of short wall portions 43 are provided on the outer periphery of the tray body 41. The pair of long wall portions 42 are wall-like members that face each other and extend along the left-right direction (first direction) of the tray 40. The pair of short wall portions 43 are wall-like members that face each other and extend along the front-back direction (second direction) of the tray 40. The upper ends of the pair of long wall portions 42 and the pair of short wall portions 43 protrude slightly upwards from the edge of the first region 50 (described later). This prevents tools and other implements used in the fusion splicing operation placed in the first region 50 from falling outside the tray body 41. Of the pair of long wall portions 42, the long wall portion 42 located on the front side of the tray 40 is designated as front long wall portion 42a (one long wall portion), and the long wall portion 42 located on the rear side of the tray 40 is designated as rear long wall portion 42b. In addition, of the pair of short wall portions 43, the short wall portion 43 located on the left side of the tray 40 is designated as left short wall portion 43a, and the short wall portion 43 located on the right side of the tray 40 is designated as right short wall portion 43b.

[0080] The front long wall portion 42a is the part that abuts against the operator's body during the welding operation. The surface of the front long wall portion 42a has a gently curved shape that slightly convexes from the outer side (front side) towards the inner side (rear side) of the tray body 41. As a result, the front long wall portion 42a fits snugly against the operator's body, thereby improving the stability of the tray 40. The front long wall portion 42a has a pair of first mounting portions 44 for mounting a belt that is wrapped around the operator's waist. Each first mounting portion 44 is provided at the left and right ends of the front long wall portion 42a, respectively. Each first mounting portion 44 is formed in a ring shape, through which a belt can be inserted. The operator can pass the belt wrapped around their waist through each first mounting portion 44 and perform the welding operation while the tray 40 is secured.

[0081] The left short wall portion 43a and the right short wall portion 43b each have a second mounting portion 45 for assembling a strap that wraps around the operator's neck. Each second mounting portion 45 is located approximately at the center of the left short wall portion 43a and the right short wall portion 43b in the front-rear direction of the tray 40. Each second mounting portion 45 is formed by two holes that extend through the tray 40 in the left-right direction. During welding operations, the operator first passes the hooks (e.g., loops) at both ends of the strap through the two holes, thereby assembling the strap to the tray body 41. Then, the operator hangs the strap around their neck, thus enabling welding operations to be performed without continuously holding the tray body 41.

[0082] On the right side of the rear long wall portion 42b and the front side of the right short wall portion 43b, there are recesses 46 and 47 that are recessed into the inside of the tray body 41. The recesses 46 and 47 form tray cuts. These recesses 46 and 47 connect the space above the tray 40 to the space below the tray 40 when the tray 40 is stored in the box body 10. Here, refer to... Figure 11 The storage solution for tray 40 is explained.

[0083] like Figure 11 As shown, the tray 40 is retracted inward from the opening of the main body 10. The lower ends of the front long wall portion 42a and the rear long wall portion 42b of the tray body 41 abut against the stepped surface 20 of the main body 10. The internal space of the storage box 1 is divided into an upper storage space S1 and a lower storage space S2 by the tray 40. The upper storage space S1 is the space enclosed by the cover 30 (not shown) and the tray 40. The upper storage space S1 can store welding equipment 100, a remover, and containers for storing medicines. The lower storage space S2 is the space enclosed by the main body 10 and the tray 40. The lower storage space S2 can store AC adapters or batteries used to power the welding machine 100.

[0084] Cutouts 46 and 47 connect the upper storage space S1 to the lower storage space S2. For example, assuming that a power cable with an AC adapter is used to power the fusion splicer 100, the AC adapter is stored in the lower storage space S2. In this case, the portion of the power cable extending from the AC adapter to the fusion splicer 100 is led out from the lower storage space S2 to the upper storage space S1 via cutout 46. On the other hand, the portion extending from the AC adapter to an external power source is led out from the lower storage space S2 to the upper storage space S1 via cutout 47. The portion of the power cable led out from cutout 47 to the upper storage space S1 can also be led out to the outside of the storage box 1 via the insertion portion 5 (cutout 18, cutout 38) of the storage box 1.

[0085] like Figure 9 and Figure 10 As shown, the pallet body 41 has a first region 50 and a second region 60, divided by a pair of long walls 42 and a pair of short walls 43. The first region 50 is located on one side (upper side) of the pallet body 41 in the vertical direction (third direction) of the pallet 40. The second region 60 is located on the opposite side (lower side) of the pallet body 41 in the vertical direction of the pallet 40.

[0086] like Figure 9 As shown, the first region 50 is a roughly rectangular area when viewed from above. Various equipment, such as the welding machine 100 used in the welding operation, are placed in the first region 50. A mounting section 51 for mounting the welding machine 100 is provided in the roughly central part of the first region 50. The mounting section 51 has a shape that is recessed inward toward the tray body 41 and has a bottom surface that is large enough to hold the welding machine 100. The bottom surface is roughly rectangular when viewed from above.

[0087] A front limiting part 52, a pair of side limiting parts 53, and a rear limiting part 54 are provided around the mounting part 51 to restrict the movement of the welding machine 100 mounted on the mounting part 51. The front limiting part 52 is a wall-like member that rises upward from the first region 50 and is configured to surround the front corner of the mounting part 51. Each side limiting part 53 is an arched member having two pillars arranged in the front-rear direction of the tray 40 and a rod-shaped connecting part that extends in the front-rear direction and connects the upper ends of the two pillars. The pair of side limiting parts 53 are configured to sandwich the mounting part 51 in the left-right direction of the tray 40. The rear limiting part 54 is a plate member that connects the rear ends of the pair of side limiting parts 53. A plurality of receiving recesses 55 are provided in the first region 50 that are recessed into the inside of the tray body 41. Containers of medicines used in the welding operation (e.g., hand pump reagent bottles) are received in the receiving recesses 55. Furthermore, a plurality of insertion recesses 56 recessed inward toward the tray body 41 are provided near the front elongated wall portion 42a in the first region 50. These insertion recesses 56 are for the insertion portion 83 of the second body abutment member 80 (described later). Figure 14 )insert.

[0088] like Figure 10 As shown, the second region 60 is a roughly rectangular area when viewed from above, located opposite the first region 50. The second region 60 has multiple recesses 61 that are recessed inwards towards the inside of the tray body 41. By providing the recesses 61, a void is created inside the tray body 41, achieving a lightweight design for the tray body 41. Furthermore, multiple beams 62 extending linearly between the multiple recesses 61 are provided, thereby suppressing any reduction in the strength of the tray body 41. The shape of the second region 60 is not limited to the shape described above; it can also be a flat surface. The first body-blocking member 70 and the second body-blocking member 80 can be housed within the second region 60.

[0089] Reference Figures 12 to 15 The detailed structure of the first body-blocking member 70 and the second body-blocking member 80 will be explained. Figure 12 This is a perspective view representing the first body impact component 70. Figure 13 This is an enlarged view of the recess 72a of the first body contact member 70 and the protrusion 65a of the locking member 65, in the retracted state of the first body contact member 70. Figure 14 This is a perspective view showing the second body-blocking component 80. Figure 15 This is a perspective view of the tray 40 in the unfolded state of the first body-blocking member 70 and the second body-blocking member 80.

[0090] The first body-impact component 70 is a component that comes into contact with the operator's body during the welding operation. For example... Figure 12As shown, the first body-blocking member 70 has a pair of shaft portions 71, a pair of connecting portions 72, a main body portion 73, and a pair of feet 74. The pair of shaft portions 71 are cylindrical members extending in the same direction. The pair of shaft portions 71 are located in a position separated from each other in the extending direction. Each shaft portion 71 is inserted into a recess (not shown) provided in the second region 60 of the tray body 41. The pair of shaft portions 71 and the recess provided in the tray body 41 function as a hinge mechanism. Thus, the first body-blocking member 70 can be in a stowed state arranged along the extending direction of the tray body 41 (see reference). Figure 10 ) and the unfolded state of being erected on the tray body 41 (refer to) Figure 15 Transfer between ) . For example Figure 15 As shown, the first body-blocking member 70 is arranged along the extension direction of the front long wall portion 42a in the unfolded state.

[0091] like Figure 12 As shown, a pair of connecting portions 72 are components that connect a pair of shaft portions 71 and a main body portion 73. Each connecting portion 72 has a recess 72a on its inner surface. This recess 72a is configured to engage with a protrusion 65a of the locking member 65. Here, the locking member 65 will be described. Figure 10 As shown, the locking member 65 is located in the second region 60 of the tray body 41. The locking member 65 is a member that maintains the retracted state of the first body-blocking member 70. Figure 13 As shown in the enlarged view, the locking member 65 has a pair of protrusions 65a on its outer side. In the retracted state of the first body contact member 70, each protrusion 65a of the locking member 65 engages with each recess 72a of the first body contact member 70, thereby locking the first body contact member 70 in place. This maintains the retracted state of the first body contact member 70. When transferring the first body contact member 70 from the retracted state to the unfolded state, the two ends of the locking member 65 are moved inwards (…). Figure 13 Press in (in the direction of arrow D) to release the locking of the first body contact member 70.

[0092] like Figure 12 As shown, the main body 73 and the pair of feet 74 are slender plate-like members. In the deployed state of the first body-blocking member 70, as... Figure 15 As shown, the main body 73 extends along the front long wall 42a in the left-right direction of the tray 40. Furthermore, a pair of feet 74 extend along the vertical direction of the tray 40, with their ends in the left-right direction of the main body 73 as bases, in a direction away from the tray body 41. Figure 12 As shown, each foot 74 has a recess 74a on the inner side of its top portion. Figure 10As shown, in the retracted state of the first body-blocking member 70, the second body-blocking member 80 is housed in the space between the pair of feet 74. At this time, the protrusion 84a of the second body-blocking member 80 (described later) engages with the recess 74a of each foot 74, thereby preventing the second body-blocking member 80 from falling out between the pair of feet 74.

[0093] like Figure 15 As shown, the length Z of each foot 74 is greater than the length (thickness) X of the pallet body 41 along the vertical direction. For example, the length Z of each foot 74 can be more than twice the length X of the pallet body 41. The length X of the pallet body 41 can be, for example, more than 40 mm and less than 80 mm. The length Z of each foot 74 can be, for example, more than 80 mm and less than 120 mm. Furthermore, the width Y of the main body portion 73 along the vertical direction of the pallet body 41 is smaller than the length Z of each foot 74. For example, the width Y of the main body portion 73 can be less than half or less than one-quarter of the length Z of each foot 74.

[0094] In the retracted state of the first body-blocking component 70, such as Figure 10 As shown, the second body-blocking member 80 can be housed in the space between the pair of feet 74. Furthermore, a connecting portion E for connecting a tripod that supports the tray 40 is provided in the second region 60 of the tray 40. Figure 10 In the diagram, the connecting part E coincides with the second body abutment member 80, and is therefore indicated by a dashed line. The connecting part E exists between a pair of legs 74 when viewed from a third-party perspective. The connecting part E is located in the space between the pair of legs 74 in the vertical direction of the tray body 41 (in...). Figure 10 The space where the second body-blocking member 80 is located overlaps with the space where the second body-blocking member 80 is located. That is, the tripod can be connected to the connecting part by removing the second body-blocking member 80.

[0095] like Figure 12 As shown, the main body 73 and the pair of feet 74 have outer surfaces 75 that contact the body of the operator performing the welding operation. The outer surfaces 75 are the surfaces of the main body 73 and the pair of feet 74 in the unfolded state of the first body contact member 70 (see reference). Figure 15 The outer surface 75 is the outermost (frontmost) surface extending from the inner (rear) side of the tray body 41 towards the outer (front) side. The outer surface 75 has a gently sloping curved shape that slightly convexes towards the inner (rear) side of the tray body 41. The outer surface 75 may also be partially curved rather than entirely curved. For example, only the surface of the main body 73 may be curved. Alternatively, the outer surface 75 may be entirely flat without a curved shape.

[0096] The second body-blocking component 80 is a component that comes into contact with the operator's body during the welding operation. For example... Figure 14As shown, the second body-blocking member 80 has a plate portion 81, a pair of insertion portions 83, and a pair of protrusions 84a. The plate portion 81 is a rectangular plate-shaped member when viewed from above. The plate portion 81 has an outer surface 82. The outer surface 82 is in the unfolded state when the second body-blocking member 80 is erected on the tray body 41 (see reference). Figure 15 The outer surface 82 is located on the outer side (front side) of the tray body 41, extending from the inner (rear) side towards the outer (front) side. The outer surface 82 has a gently convex, slightly curved shape that bulges towards the inner (rear) side of the tray body 41. The outer surface 82 may also be partially curved rather than entirely curved. Alternatively, the outer surface 82 may be entirely flat without a curved shape.

[0097] A pair of insertion portions 83 protrude from the lower end of the plate portion 81 toward the outer side of the plate portion 81. Each insertion portion 83 can be inserted into... Figure 9 The first region 50 shown has an insertion recess 56. The insertion portion 83 has a structure that allows the second body contact member 80 to be attached to and detached from the tray body 41. Thus, the second body contact member 80 can be in a stowed state arranged along the extending direction of the tray body 41 (see reference). Figure 10 ) and the unfolded state of being erected on the tray body 41 (refer to) Figure 15 Transfer between ) . For example Figure 15 As shown, the second body-blocking member 80 is arranged along the extension direction of the front long wall portion 42a in the unfolded state.

[0098] A pair of protrusions 84a are provided on the upper part of a pair of lateral sides 84 facing each other in a manner that clamps the outer surface 82. As described above, when the second body-blocking member 80 is housed in the space between a pair of feet 74 (see reference...) Figure 10 Each protrusion 84a fits into a recess 74a respectively provided on a pair of feet 74, thereby preventing the second body impact member 80 from falling out of the space between the pair of feet 74.

[0099] As described above, the tray 40 for welding operations in this embodiment is provided with a first body-blocking member 70, which can move between an unfolded state and a retracted state. Therefore, when performing welding operations, by unfolding the first body-blocking member 70, the operation can be performed while keeping the tray 40 stable. On the other hand, when storing the tray 40, by retracting the first body-blocking member 70, it can be easily stored in the storage box 1.

[0100] In this embodiment, the tray body 41 has a first region 50 where a mounting portion 51 is provided and a second region 60 in the tray body 41 that is opposite to the first region 50 in a third direction. A first body-blocking member 70 is connected to the tray body 41 in the second region 60 via a hinge mechanism. In this case, the first body-blocking member 70 is located in the second region 60 on the side opposite to the first region 50 where the mounting portion 51 of the welding machine 100 is provided. As a result, the first body-blocking member 70 can be stored along the second region 60 without contacting the welding machine 100. Consequently, when storing the first body-blocking member 70, it is not necessary to remove the welding machine 100 from the tray 40 or move it from the mounting portion 51, and it can be stored as is.

[0101] In this embodiment, the first body-blocking member 70 includes: a main body portion 73, which, in the unfolded state, extends in a first direction along the edge of a long wall portion 42 (front long wall portion 42a) of the tray body 41 on which the first body-blocking member 70 is mounted; and a pair of feet 74, which extend in a third direction away from the tray body 41, with the two ends of the main body portion 73 in the first direction as base ends. In this case, when the first body-blocking member 70 is in the stowed state, other components (e.g., the second body-blocking member 80) can be stored in the space between the pair of feet 74, thereby improving storage efficiency.

[0102] In this embodiment, the length Z of each pair of feet 74 is greater than the length X of the tray body 41 along a third direction. As the length of the feet 74 increases, the outer surface 75 of the first body contact member 70, which comes into contact with the body of the operator using the welding machine 100, can be further enlarged. Therefore, according to this embodiment, the outer surface 75 of the first body contact member 70 can be ensured to be large, thereby improving the stability of the tray 40 during operation.

[0103] In this embodiment, the width Y of the main body 73 along the third direction in the unfolded state may be less than half the length of each of the pair of feet 74. In this case, a large space can be ensured between the pair of feet 74, thereby further improving storage efficiency.

[0104] In this embodiment, the tray body 41 has a connecting portion E for connecting a tripod that supports the tray 40. In the stowed state, the connecting portion E is located between a pair of legs 74 when viewed from a third-party perspective. In this case, even when the first body-blocking member 70 is stowed, the tripod can be connected to the connecting portion E of the tray body 41 without obstructing the first body-blocking member 70.

[0105] In this embodiment, the outer surface 75 of the first body contact member 70 includes a curved portion that protrudes in a direction from the outside to the inside of the tray body 41. In this case, during welding operations, the outer surface 75 of the first body contact member 70 conforms to the operator's body, thereby improving the stability of the tray 40.

[0106] In this embodiment, a second body-blocking member 80 is also provided. This second body-blocking member 80 is detachably mounted to the tray body 41 on one of the long wall portions 42 and on the side opposite to the first body-blocking member 70. In this case, the tray 40 not only has the first body-blocking member 70 but also the second body-blocking member 80, thereby further improving the stability of the tray 40 during welding operations. Furthermore, the second body-blocking member 80 can be detached from the tray body 41, thus facilitating the storage of the tray 40 in the storage box 1.

[0107] In this embodiment, the tray body 41 includes: a first mounting portion 44, located on one of a pair of long wall portions 42, for mounting a belt that wraps around the operator's waist; and a second mounting portion 45, located on both sides of a pair of short wall portions 43, for mounting a strap that wraps around the operator's neck. In this case, by securing the tray body 41 with the belt, the stability of the tray 40 during welding operations is improved. Furthermore, by hanging the strap attached to the tray body 41 around the neck, the operator can maintain the tray 40 near their body while performing the operation, even without continuously holding the tray body 41 with their hands. Therefore, the efficiency of the welding operation is improved.

[0108] In this embodiment, at least one of the pair of long wall portions 42 and the pair of short wall portions 43 is provided with a cutout 46 or a cutout 47 that is recessed into the inside of the tray body 41. In this case, when the tray 40 is stored in the storage box 1, devices respectively disposed in the space separated by the tray 40 (upper storage space S1 and lower storage space S2) can be connected to each other by cables via the cutout 46 or the cutout 47.

[0109] The embodiments of this disclosure have been described in detail above, but the present invention is not limited to the above embodiments and can be applied to a variety of embodiments.

[0110] Alternatively, the insertion part 5 for cable insertion can be a through hole provided in the first peripheral wall 12 of the main body 10 or the second peripheral wall 32 of the cover 30, instead of the cutout 18 or cutout 38. In this case, the through hole can also be provided in the bottom plate 11 of the main body 10 or the top plate 31 of the cover 30.

[0111] Alternatively, the first body-blocking member 70 and the second body-blocking member 80 can be detached from the tray body 41. In this case, the state of being detached from the tray body 41 is equivalent to the stored state of the first body-blocking member 70. Furthermore, the first body-blocking member 70 and the second body-blocking member 80 can also have a rectangular plate shape when viewed from above.

[0112] Alternatively, the second body-blocking member 80, like the first body-blocking member 70, can be connected to the tray body 41 via a hinge mechanism and can be stored by folding towards the first region 50 of the tray body 41. In this case, the second body-blocking member 80 may also have a U-shaped central cavity (the same shape as the first body-blocking member 70) so that it does not come into contact with the welding machine 100 or the like in the stored state.

[0113] Alternatively, to facilitate the transition between the unfolded and retracted states, the first body contact member 70 and the second body contact member 80 may be equipped with handles that can be gripped by the operator.
