Description

The present invention includes a solder wire holder that holds a solder wire coil formed by winding a solder wire into a cylindrical shape, a solder wire holding mechanism equipped with this solder wire holder, and a solder wire holder. The present invention relates to a soldering device, a soldering method using a solder wire holder, and a method for disassembling a solder wire holder.

2. Description of the Related Art Conventionally, solder used for joining parts of electronic devices and the like has often been a type called wire solder, which is formed into a long and thin linear shape. Such wire solder is generally used in a state where it is wound around a plastic cylindrical body (bobbin) in consideration of handling during soldering. After the solder wire is used up, the above-mentioned bobbin is disposed of as plastic waste, and there is a problem that the environment is polluted by being dumped into the ocean.

Therefore, a cylindrical core member around which a solder wire coil is wound, and two flanges provided at both ends of the core member, at least one of the flange parts is removably screwed onto the core member, and the solder wire A reusable solder wire fixture configured to allow a coil to be attached and detached has been proposed (see, for example, Patent Document 1).

In addition, the present inventors have developed a first shape-retaining member having a cylindrical outer core inserted into a center hole of a solder wire coil and a first flange portion that covers one end surface of the solder wire coil; a second shape-retaining member having an inner core body to be inserted into the solder wire coil and a second flange portion covering the other end surface of the solder wire coil, and the outer core body has a plurality of slits extending in the axial direction from the tip thereof. At the same time, a protrusion extending in the circumferential direction is formed on the inner circumferential surface of the outer core body, and an engagement groove in which the protrusion is engaged is formed on the outer circumference surface of the inner core body. We have developed a solder wire holder (for example, see Patent Document 2).

In the solder wire coil fixture disclosed in Patent Document 1 mentioned above, a new solder wire coil can be attached after the solder wire coil is consumed, so the solder wire coil fixture is discarded as plastic waste. can be prevented. However, the solder wire coil fixture described above is used by sequentially pulling out the solder wire from the fixture while being supported by the support shaft of the solder supply device. As a result, the threaded connection between the core member and the flange portion may be gradually loosened, and the flange portion may come off, making it difficult to stably hold the solder wire coil.

On the other hand, in the solder wire holder disclosed in Patent Document 2, the inner core of the second shape retaining member is inserted into the outer core of the first shape retaining member, and the protrusions of the outer core are inserted into the inner core of the first shape retaining member. Since the flange portion is configured to engage with the engagement groove of the solder wire, the flange portion will not come off when the solder wire is pulled out. However, with the solder wire holder described above, when replacing the solder wire coil held by the solder wire holder, the user manually moves the pair of divided pieces to open and expand the outer core. After the protrusion of the outer core body is operated to disengage from the engagement groove of the inner core body, it is necessary to disassemble the first shape retention member and the second shape retention member, which poses the problem of poor workability. there were.

In particular, when the solder wire coil in use is held in the holder, it is extremely difficult to swing the pair of divided pieces to open and expand the outer core. For this reason, for example, the user can remove the inner core of the second shape-retaining member from the outer core of the first shape-retaining member by providing play between the protrusion of the outer core and the engagement groove of the inner core. It is necessary to configure it so that it can be pulled out by force, and there is a problem in that the protrusions on the outer core body or the engagement grooves on the inner core body are likely to be damaged during this pull-out operation. Moreover, due to the play formed between the protrusions of the outer core body and the engagement grooves of the inner core body, looseness is likely to occur in the connected state of the first shape retaining member and the second shape retaining member, and the solder wire There was a problem that the coil could not be held stably.

This prevents the first shape-retaining member and the second shape-retaining member from separating when soldering is performed by sequentially drawing out the solder wire from the solder wire coil. In addition, the user can push the locking protrusion out of the locking groove by inserting the protrusion of the locking release jig into the communication groove and the locking groove. Since the fixed state of the protrusion can be easily and properly released, simply by pulling the inner core of the second shape retaining member out of the outer core of the first shape retaining member, the first shape retaining member and the second shape retaining member can be released.

The joint portion 24 and the pair of communication grooves 26 are arranged to intersect in a cross shape in a plan view. Therefore, the engaging portion 24 of the inner core body 21 is engaged with the positioning portion 17 of the outer core body 11, and positioning of the first shape retaining member 1 and the second shape retaining member 2 in the circumferential direction is performed. Accordingly, in a plan view of the second shape-retaining member 2 shown in FIG. 16, the communication groove 26 of the inner core body 21 and the locking claw 15 of the outer core body 11 are arranged in an overlapping position.

Like the first flange part 12 of the first shape-retaining member 1, the second flange part 22 has an outer diameter approximately equal to or slightly larger than the outer diameter dimension of the solder wire coil H, for example, an outer diameter d3 of 65 mm. It is formed into a disc shape with a When the solder wire coil H is held by the solder wire holder 10, the other end surface of the solder wire coil H is covered and protected by the second flange portion 22. Further, the plate thickness t (see FIG. 13) of the second flange portion 22 is set to a value slightly larger than that of the first flange portion 12 of the first shape-retaining member 1, for example, about 3 mm.

FIG. 17 is a perspective view of the fixing release jig 3 that constitutes the solder wire holding mechanism 20 according to the first embodiment of the present invention, viewed diagonally from below; FIG. 18 is a front view of the fixing release jig 3; FIG. 19 is a bottom view of the attachment release jig 3, and FIG. 20 is a plan view of the attachment release jig. Note that the rear view of the attachment release jig 3 is the same as the front view of the attachment release jig 3 shown in FIG.

As shown in FIG. 19 etc., the fixing release jig 3 includes a donut-shaped substrate 31, a connecting plate 32 that connects the inner sides of the substrate 31, and one surface of the connecting plate 32. In this embodiment, it has a protrusion 33 provided on a surface located on the bottom side of the fixing release jig 3. The substrate 31 has an outer diameter α1 (see FIG. 19) set to approximately the same value as the outer diameter d3 (about 65 mm) of the second flange portion 22, and an inner diameter α2 of about 45 mm, and the connecting plate 32 The width dimension β is set to about 7 mm.

That is, the plate thickness γ1 (see FIG. 19) of the protrusion 33 is set to be the same as or slightly smaller than the groove width v1 (about 3 mm) of the communication groove 26, for example, about 2.5 mm. Further, the left-right width γ2 of the protrusion 33 is approximately the same as the extension distance v2 (about 35 mm) of the communication groove 26 in a plan view of the second shape-retaining member 2, or a value slightly smaller than this, for example, about 34.5 mm. is formed.

Furthermore, the vertical dimension γ3 (see FIG. 18) of the protrusion 33 protruding in the Y-axis direction in FIG. is set to the value of In addition, in order to facilitate the operation when inserting the protrusion 33 into the communication groove 26 of the second shape retaining member 2 as described later, R is provided on both left and right sides of the protrusion 33. A chamfered portion 34 having a shape is formed.

Then, when the user disassembles the first shape-retaining member 1 and the second shape-retaining member 2 that are in the coupled state, the user inserts the protrusion 33 of the attachment release jig into the communication groove 26 of the second shape-retaining member 2. When inserted, the side surface of the protrusion 33 comes into contact with the locking protrusion 14 of the first shape-retaining member 1 . As a result, as will be described later, the protrusion 33 pushes the locking protrusion 14 to the outside of the locking groove 23 of the second shape-retaining member 2, and the locking protrusion 23 engages the locking groove 23. 14 is released (see FIG. 30).

The above-mentioned first shape retaining member 1, second shape retaining member 2, and attachment releasing jig 3 are made of a material having a predetermined rigidity such as ABS resin, polycarbonate resin, nylon resin, polyurethane resin, fluororesin, vinyl resin, or PTFT. and a material having appropriate elasticity. In addition, in order to form the first shape-retaining member 1 etc. having sufficient strength, it is preferable to form these from ABS resin or polycarbonate resin. Furthermore, in consideration of the colorability when coloring the first shape retaining member 1 etc. in various colors, it is more preferable to form these with ABS resin.

In addition, the first shape retaining member 1, the second shape retaining member 2, and the fixing release jig 3 can be formed by injection molding using an injection molding machine, cutting processing using a cutting machine, or modeling processing using a 3D printer. It is appropriately molded by means such as the above. In addition, it is also possible to form the first shape-retaining member 1 and the second shape-retaining member 2 by cutting a metal material or wood.

Furthermore, the solder wire holder 10 is configured by coloring the first shape retaining member 1, the second shape retaining member 2, etc. in various colors, and selecting and combining colors according to the user's preference. It's okay. Furthermore, the first shape-retaining member 1 and the second shape-retaining member 2, etc. are color-coded to correspond to the type, material, etc. of the solder wire coil H held in the solder wire holder 10. The configuration may be such that the type, material, etc. of the solder wire coil H held by the wire holder 10 can be confirmed at a glance.

21 is a perspective view showing the specific structure of the solder wire coil H, FIG. 22 is a sectional view showing the specific structure of the solder wire coil H, and FIG. 23 is a perspective view showing the specific structure of the solder wire coil H. 24 is a cross-sectional view showing the process of joining the first shape-retaining member 1 and the second shape-retaining member 2, and FIG. It is a sectional view showing an inserted state.

The solder wire coil H includes a coil main body H1 formed into a cylindrical shape by winding the solder wire, a coating film H2 that covers the outer surface of the coil body H1, and a side surface of one end of the solder wire coil H (the upper side surface of FIG. 22). ) is provided with a substantially donut-shaped label H3 attached to the upper surface of a covering film H2 that covers the cover film H2. Openings H21 and H31 corresponding to the upper opening of the center hole H11 formed in the coil main body H1 are formed in the covering film H2 and the label H3, respectively. Further, an opening H32 corresponding to the lower opening of the center hole H11 is formed in the covering film H2.

The covering film H2 is formed of, for example, a heat-shrinkable film material. Specifically, for example, a cylindrical body made of a heat-shrinkable film material is fitted onto the coil main body H1 and heat-shrinked, thereby forming a covering film H2 that covers the outer surface of the coil main body H1. can do.

Heat-shrinkable film materials for the covering film H2 include positive vinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene (PS), polyolefin (PO), polyethylene terephthalate (PET), and polycarbonate (PC). ), ethylene-vinyl alcohol copolymer (EVA), etc., and various heat-shrinkable materials such as two layers such as PET/PET and PP/PE, and combinations of the above-mentioned materials in multiple layers can be used.

As the label H3 of the solder wire coil H, various materials can be used, such as a sheet-like body such as paper or a resin sheet. Various information is written on the surface of the label H3, including the manufacturer's name, symbols indicating the type and material of the solder wire, the thickness of the solder wire, the weight of the solder wire coil H, the lot number, etc. .

To hold the solder wire coil H in the solder wire holder 10, first insert the outer core 11 of the first shape retaining member 1 into the center hole H11 from the lower side of the solder wire coil H, as shown in FIG. insert. Next, as shown in FIG. 24, the inner core 21 of the second shape retaining member 2 is inserted into the outer core 11 of the first shape retaining member 1 from above the solder wire coil H.

At this time, by using the inner tapered surface 27 provided at the tip of the inner core body 21 as a guide surface, the insertion operation of the inner core body 21 into the outer core body 11 can be easily performed. . Further, when the inner core body 21 is inserted into the outer core body 11 beyond the installation part of the tapered surface 27, the outer peripheral surface of the inner core body 21 comes into contact with the locking protrusion 14 of the locking pawl 15 ( (See Figure 24). Then, by sliding the outer peripheral surface of the inner core body 21 along the tapered surface 14a of the locking protrusion 14, the locking protrusion 14 is pushed radially outward of the outer core body 11. As a result, the locking pawl 15 becomes elastically deformed.

At the final stage of the joining process between the first shape retaining member 1 and the second shape retaining member 2, as shown in FIG. 25, when the inner core body 21 is inserted deep into the outer core body 11, the second shape retaining member The engaging portion 24 of the member 2 comes into contact with the outer core body 11 of the first shape-retaining member 1 and the tip of the locking claw 15, thereby preventing the insertion operation of the inner core body 21 into the outer core body 11. As a result, the user confirms that the inner core body 21 has been inserted deeply into the outer core body 11, and at this point the user confirms that the inner core body 21 has been inserted deeply into the outer core body 11. By rotating the flange portion 22, the engaging portion 24 and the positioning portion 17 are aligned.

When the engaging part 24 of the second shape-retaining member 2 reaches the position facing the positioning part 17 of the first shape-retaining member 1 in accordance with the rotation operation of the second flange part 22, as shown by the broken line in FIG. , the engaging part 24 is inserted into the positioning part 17. As a result, the lower surface of the second flange portion 22 comes into contact with the tip of the outer core body 11, and the locking protrusion 14 of the outer core body 11 faces the locking groove 23 of the inner core body 21, The locking protrusion 14 is fitted into the locking groove 23 according to the restoring force of the locking claw 15. At this time, since a "click" operation sound is generated, the user can clearly recognize that the coupling operation between the first shape retaining member 1 and the second shape retaining member 2 has been completed.

By thus joining the first shape retaining member 1 and the second shape retaining member 2, the solder wire coil H is held in the solder wire holder 10 as shown in FIG. Become. Then, with the solder wire holder 10 supported by a support shaft 41 provided in a soldering device 40, which will be described later, the solder wires are sequentially fed out from the solder wire holder 10, thereby performing the soldering work. be able to.

FIG. 26 is a perspective view showing a schematic configuration of a soldering device 40 that performs soldering using the soldering wire holder 10, FIG. 27 is a process diagram showing a soldering method using the soldering device 40, and FIG. , a process diagram showing a specific example of the solder wire holding step K1 carried out in the soldering method of FIG. 27, FIG. 29 is a process diagram showing a method of disassembling the solder wire holder 10, and FIG. 31 is a right side view showing a modified example of the second shape retaining member 2, and FIG. 32 is a bottom view showing a modified example of the fixing release jig 3.

The soldering device 40 generally includes a soldering wire support section 42 equipped with a support shaft 41 that supports the solder wire holder 10 , a soldering section 44 provided with a soldering iron 43 , and a soldering wire holder 10 . A solder wire supply section 46 that supplies the drawn out solder wire 45 to the soldering section 44 is provided.

As shown in FIG. 27, the soldering method using the solder wire holder 10 described above includes a solder wire holding step K1 in which the solder wire coil H is held in the solder wire holder 10, and a solder wire holding step K1 in which the solder wire coil H is held in the solder wire holder 10, and a solder wire coil H is pulled out from the solder wire holder 10. The soldering process K2 includes a soldering process K2 in which the solder wire is supplied to the soldering part 44, and a soldering process K3 in which the soldering wire is melted and soldered in the soldering part 44.

Furthermore, as shown in FIG. 28, the solder wire holding step K1 described above includes a disassembly step K11 in which the solder wire holder 10 is disassembled into a first shape retaining member 1 and a second shape retaining member 2, and an outer core body 11. A first insertion step K12 in which the solder wire coil H is inserted into the center hole H11 of the solder wire coil H, a second insertion step K13 in which the inner core body 21 is inserted into the outer core body 11, and the engaging portion 24 is engaged with the positioning portion 17. and a fastening step K14 in which the locking protrusion 14 is fastened to the fastening groove 23.

As shown in FIG. 29, the method for disassembling the solder wire holder carried out in the above-mentioned disassembly step K11 includes a fixing release step K21 in which the fixing state of the fixing protrusion 14 to the fixing groove 23 is released; It includes a separation step K22 for separating the first shape-retaining member 1 and the second shape-retaining member 2.

In the fastening release step K21, the communication groove 26 and the fastening groove are removed in the solder wire holder 10 (see FIG. 1) in which the first shape-retaining member 1 and the second shape-retaining member 2 are joined together. As shown in FIG. 30, the protrusion 33 of the fixing release jig 3 is inserted into the locking groove 23 to push the locking protrusion 14 out of the fixing groove 23. As a result, the locking state of the locking protrusion 14 with respect to the locking groove 23 is released, and in the above-mentioned separation step K22, the inner core body 21 of the second shape retaining member 2 is removed from the outer core of the first shape retaining member 1. By pulling it out of the body 11, the operation of separating the first shape-retaining member 1 and the second shape-retaining member 2 can be performed smoothly.

After disassembling the first shape-retaining member 1 and the second shape-retaining member 2 as described above, the outer core body 11 is inserted into the center hole H11 of the solder wire coil H in the first insertion step K12 in FIG. (See FIG. 23), and in the second insertion step K13 of FIG. 28, the inner core body 21 is inserted into the outer core body 11 (see FIGS. 24 and 25). 28, the second flange portion 22 is rotated as shown by the arrow A in FIG. 25 to engage the engaging portion 24 with the positioning portion 17 for locking. The protrusion 14 is fastened to the fastening groove 23. As a result, the first shape-retaining member 1 and the second shape-retaining member 2 are joined together, and the solder wire coil H is held by the solder wire holder 10, as shown in FIG.

The cylindrical outer core body 11 inserted into the center hole H11 of the solder wire coil H formed by winding the solder wire in a cylindrical shape as described above and the first flange portion 12 that covers one end surface of the solder wire coil H are provided. a second shape-retaining member 2 having an inner core body 21 inserted into the outer core body 11 and a second flange portion 22 covering the other end surface of the solder wire coil H; The outer core body 11 is formed with a pair of notches 13 extending in the axial direction from its tip, and between the pair of notches 13 is a locking groove that protrudes inward of the outer core body 11. A solder wire holder is provided with a locking pawl 15 having a protrusion 14, and a locking groove 23 in which the locking protrusion 14 is removably locked is formed on the inner peripheral surface of the inner core body 21. According to the tool 10, the inner core body 21 of the second shape retaining member 2 is inserted into the outer core body 11 of the first shape retaining member 1, and the locking protrusion 14 of the outer core body 11 is inserted into the inner core body. 21, the first shape-retaining member 1 and the second shape-retaining member 2 can be joined together, and the solder wire coil H can be easily held.

When the user performs soldering, for example, by sequentially drawing out the solder wire 45 from the solder wire coil H while the solder wire holder 10 is supported by a support shaft 41 provided on the soldering device 40. In addition, separation of the first shape-retaining member 1 and the second shape-retaining member 2 is reliably prevented, and the solder wire coil H can be stably held. That is, according to the solder wire holder 10 according to the present invention, unlike the conventional technology disclosed in Patent Document 1, the threading between the core member and the flange portion is gradually loosened in response to the operation of feeding out the solder wire. Therefore, the supporting state of the solder wire coil H can be stably maintained.

Moreover, as described above, the outer circumferential surface of the inner core body 21 is provided with the engaging part 24 that engages with the positioning part 17 formed of a slit provided in the outer core body 11, and the second flange part 22 and A communication groove 26 communicating with the fastening groove 23 is formed in the inner core body 21 . As a result, when the engaging part 24 is engaged with the positioning part 17, the locking protrusion 14 and the communication groove 26 are arranged so as to overlap in a plan view of the second shape-retaining member 2. When the user inserts the protrusion 33 of the locking release jig 3 into the communication groove 26 and the locking groove 23, the locking protrusion 14 is pushed out of the locking groove 23, and the locking groove 23 is pushed out. The locked state of the locking protrusion 14 can be easily and appropriately released.

That is, in the conventional technology disclosed in Patent Document 2, when the solder wire coil is used up, the user swings a pair of left and right divided pieces through a slit formed in the outer cylinder. Then, manually disengage the locking protrusion on the outer core from the locking groove on the inner core, and then remove the protrusion on the outer core from the engagement groove on the inner core. After that, a complicated operation of separating the first shape-retaining member and the second shape-retaining member was required.

On the other hand, in the solder wire holder 10 according to the present invention, as shown in FIG. By inserting the protrusion 33 of the release jig 3 into the second shape retaining member 2, etc., the fixed state of the locking protrusion 14 to the retaining groove 23 can be released, and the inside of the second shape retaining member 2 can be released. By simply pulling the core body 21 out of the outer core body 11 of the first shape retaining member 1, the first shape retaining member 1 and the second shape retaining member 2 can be easily and smoothly separated.

As a result, there is no need to provide play between the locking protrusion 14 of the outer core body 11 and the locking groove 23 of the inner core body 21, and the inner diameter D2 of the outer core body 11 and the outer diameter of the inner core body 21 d1 to approximately the same value, and the groove depth m1 and groove width m2 of the locking groove 23 to the protrusion amount U1 and axial dimension U2 (approximately 2 mm) of the locking protrusion 14. By setting it to a value, it is possible to effectively prevent the wobbling caused by the above-mentioned play from occurring between the first shape retaining member 1 and the second shape retaining member 2.

In addition, the user can easily disassemble the solder wire holder 10 and install a new one without forcibly pulling out the inner core 21 of the second shape retaining member 2 from the outer core 11 of the first shape retaining member 1. The solder wire coil H can be held. Moreover, when pulling out the inner core body 21 of the second shape retaining member 2 from the outer core body 11 of the first shape retaining member 1, the locking protrusion 14 of the outer core body 11 or the retaining groove of the inner core body 21 There is no risk of damage to the solder wire holder 23, and the solder wire holder 10 can be used any number of times. Therefore, it is possible to effectively prevent the environment from being polluted due to the solder wire holder 10 being dumped into the ocean.

Further, even in a state where the solder wire coil H remains, that is, a state where the outer core body 11 of the first shape retaining member 1 is restrained from the outside by the solder wire coil H, the user can use the fixing release jig 3 By inserting the protrusion 33 into the communication groove 26 of the second shape-retaining member 2, it is possible to release the locking protrusion 14 from the locking groove 23. Therefore, before using up the solder wire coil H, it is necessary to release the bond between the first shape retaining member 1 and the second shape retaining member 2 and replace the solder wire coil H in use with another one. It can be done easily.

In the first embodiment described above, the plate thickness of the locking claw 15 can be reduced by providing the recessed part 16 in which the outer peripheral surface is recessed in the installation part of the locking claw 15 provided on the outer core body 11. It is formed thinner than the plate thickness of the main body portion of the outer core body 11. Therefore, as shown in FIG. 1, a gap is formed between the outer circumferential surface of the locking pawl 15 and the inner circumferential surface of the solder wire coil H, corresponding to the amount of depression of the recessed part 16. The presence of the locking claw 15 allows the locking claw 15 to swing.

Moreover, even if the outer core body 11 of the first shape-retaining member 1 is made of a material having a predetermined rigidity, as shown in FIG. When inserting into the communication groove 26 of the second shape-retaining member 2 to release the locking state of the locking protrusion 14 from the locking groove 23, the locking claw 15 can be easily swung and displaced. The state in which the locking protrusion 14 is fixed to the locking groove 23 can be reliably released.

In addition, in the first embodiment described above, an example is described in which the recessed part 16, which is recessed in the outer peripheral surface of the installation part of the locking claw 15, is formed over the entire length from the distal end to the proximal end of the outer core body 11. However, it is not necessarily necessary to form the recessed part 16 over the entire length from the distal end to the proximal end of the outer core body 11, and the recessed part 16 in the portion located below the locking claw 15 may be omitted. Good too. However, in this case, stress concentration occurs at the base end of the locking pawl 15 and the base end of the locking pawl 15 is likely to be damaged. It is desirable to form the recessed portion 16 over the entire length up to the base end.

Further, in the first embodiment described above, a locking protrusion 14 is formed on the inner circumferential surface of the distal end portion of the outer core body 11, and a locking groove 23 is formed on the outer circumferential surface of the base end portion of the inner core body 21. Instead, for example, a locking protrusion 14 is formed on the inner circumferential surface located at the axially intermediate portion of the outer core body 11, and a locking groove is formed on the outer circumferential surface located at the axially intermediate portion of the inner core body 21. 23 is also possible.

However, in the above configuration, since the locking protrusion 14 and the locking groove 23 are provided at a position away from the second flange portion 22, the locking protrusion 14 and the locking groove 23 are provided through the communication groove 26 formed in the second flange portion 22. It is not possible to easily release the locking state of the locking protrusion 14 from the locking groove 23. For this reason, as shown in the first embodiment described above, by forming the locking protrusion 14 and the locking groove 23 at a position close to the second flange portion 22, the communication formed in the second flange portion 22 is It is desirable that the configuration is such that it is possible to easily release the locking state of the locking protrusion 14 from the locking groove 23 via the groove 26.

Furthermore, in the first embodiment described above, the positioning portions 17 to which the engaging portions 24 of the inner core body 21 are engaged are formed as a pair of positioning portions 17 extending from the distal end of the outer core body 11 toward its proximal end. The outer core body 11 is divided into a pair of left and right dividing pieces 18 each having a semicircular cross-sectional shape by a positioning portion 17 made of the slit. Therefore, even if the inner diameter of the solder wire coil H, that is, the diameter of the center hole H11, is smaller than the outer diameter D1 of the outer core body 11 due to manufacturing error, the outer core body can be attached to the center hole H11 of the solder wire coil H. When inserting the outer core body 11, each divided piece 18 is oscillated to reduce the diameter of the outer core body 11, which has the advantage that the insertion operation of the outer core body 11 can be performed smoothly.

Further, in the first embodiment described above, the connecting portion 17a formed thinner than the main body portion of the outer core body 11 is provided at the base end portion of the positioning portion 17 formed in the outer core body 11. Since the opposing side wall surfaces of each divided piece 18 are connected to each other by the connection part 17a, the base end of the outer core body 11 is reinforced by the connection part 17a, and the strength of the outer core body 11 is sufficiently ensured. can do. Moreover, as shown in the first embodiment described above, when the connecting portion 17a is formed thinner than the main body portion of the outer core 11, the left and right pair separated by the positioning portion 17 consisting of a slit There is an advantage that the base end of the outer core body 11 can be appropriately reinforced while preventing stress concentration from occurring at the base end of the divided piece 18.

Furthermore, in the first embodiment, since the plate thickness t (about 3 mm) of the second flange part 22 is set to a value slightly larger than the plate thickness T (about 2 mm) of the first flange part 12, the second flange part 22 Due to the reinforcing action, the strength of the solder wire holder 10 can be maintained appropriately. Moreover, since the plate thickness T of the first flange part 12 is set smaller than the plate thickness t of the second flange part 22, when inserting the outer core body 11 into the center hole H11 of the solder wire coil H, The first flange portion 12 can be easily elastically deformed. As a result, when inserting the outer core body 11 into the center hole H11 of the solder wire coil H, each divided piece 18 can be more smoothly oscillated and the outer core body 11 can be reduced in diameter. Thereby, the outer core body 11 of the first shape-retaining member 1 can be smoothly inserted into the center hole H11 of the solder wire coil H without damaging the solder wire.

Note that instead of the above-described first embodiment in which the engaging portion 24 consisting of a rectangular protrusion is provided on the outer peripheral surface of the base end of the inner core body 21, as shown in FIG. An engaging portion 24a is provided which is a protrusion extending from the end to the tip thereof, and the axial length l2 of the engaging portion 24a is equal to the axial length of the positioning portion 17 which is a slit. A configuration in which the values are set to substantially equal values may also be used. With this configuration, when inserting the inner core body 21 into the outer core body 11, the engaging portion 24a can be aligned with the positioning portion 17 in advance.

Therefore, in the final stage of the joining process between the first shape-retaining member 1 and the second shape-retaining member 2, the second flange portion 22 of the second shape-retaining member 2 is rotated as shown by arrow A in FIG. There is no need for any operation, and the locking projections 14 of the locking claws 15 can be fitted into the locking grooves 23 by simply inserting the inner core body 21 straight into the outer core body 11. In this case as well, when the locking protrusion 14 is inserted into the locking groove 23, a "click" operation sound is generated, so the user can easily connect the first shape-retaining member 1 and the second shape-retaining member 2. It is possible to clearly recognize that the join operation with has been completed.

Further, the solder wire holding mechanism 20 according to the present invention includes the solder wire holder 10 having the first shape retaining member 1 and the second shape retaining member 2 as described above, and the retaining protrusion 14 for the retaining groove 23. A locking release jig 3 is provided to release the locking state of the locking state. Furthermore, by inserting the protrusion 33 provided on the lock release jig 3 into the communication groove 26, the locking protrusion 14 is pushed in the direction of pushing out the locking groove 23. Even when a plurality of locking pawls 15 are provided on the outer core body 11, the locking state of the locking protrusion 14 with respect to the locking groove 23 can be easily released by pushing and operating these at the same time. Can be done.

That is, in the first embodiment described above, the outer core body 11 is provided with a pair of locking claws 15, the inner core body 21 is provided with a pair of communication grooves 26, and the lock release jig 3 Since the protrusions 33 are arranged at positions corresponding to the respective communication grooves 26, by inserting the right and left side portions of the protrusions 33 into the pair of communication grooves 26, the pair of locking pawls 15 can be simultaneously engaged. There is an advantage that the locking state of each locking protrusion 14 with respect to the locking groove 23 can be easily and reliably released by a pushing operation.

Note that instead of the first embodiment described above in which the outer core body 11 is provided with a pair of locking pawls 15, three or more locking pawls 15 are provided on the outer core body 11, and a corresponding number of locking pawls 15 are provided on the outer core body 11. A configuration may be adopted in which the communication grooves 26 are provided in the inner core body 21 and the protrusions 33 of the fixing release jig 3 are arranged at positions corresponding to each communication groove 26.
