{Embodiment}
Hereinafter, the manufacturing method of the anticorrosive agent supply apparatus and electric wire with a terminal concerning an embodiment is explained.

<Wire with terminal>
First, a terminal-attached electric wire to be manufactured will be described with reference to FIGS. 1 to 3. Drawing 1 is an outline side view showing electric wire 10 with a terminal used as manufacture object. FIG. 2 is a schematic plan view showing the terminal-attached electric wire 10 to be manufactured. FIG. 3 is a schematic perspective view showing the terminal 20.

  The terminal-attached electric wire 10 includes an electric wire 12, a terminal 20, and an anticorrosion coating 18.

  The electric wire 12 includes a core wire 13 and a coating 14 that covers the core wire 13. The core wire 13 is a linear conductor, and here, the core wire 13 is formed by twisting a plurality of strands. The coating 14 is made of an insulating material such as resin. The coating 14 is formed, for example, by extrusion-coating a softened resin around the core wire 13.

  Further, a coating 14 having a predetermined length is peeled off from the core wire 13 at the end of the electric wire 12. Thereby, the exposed core wire part 13a which the core wire 13 exposes over predetermined length is provided in the edge part of the electric wire 12. FIG.

  The terminal 20 is a member formed by, for example, pressing a metal plate material that is a conductive plate material, and is connected to a mating connection portion 28 that directly contacts a mating conductor C as a mating electrical connection element and its mating member. The electric wire connection part 22 connected with the side connection part 28 is provided.

  The wire connecting portion 22 includes a distal end side connecting portion 23, a core wire crimping portion 24, an intermediate connecting portion 25, and a covering crimping portion 26. The distal end side connecting portion 23, the core wire crimping portion 24, the intermediate connecting portion 25, and the covering crimping portion 26 are formed in a line along the linear direction. In the present embodiment, in the present terminal 20, the counterpart connection portion 28 side is described as the distal end side of the terminal 20, and the wire connection portion 22 side is described as the proximal end side of the terminal 20.

  The covering crimping part 26 is a part that is crimped to the end of the covering 14 of the electric wire 12 by being caulked. The covering crimping portion 26 includes a bottom plate portion 26a and a pair of covering crimping pieces 26b that are erected on both sides of the bottom plate portion 26a and face each other. In the example shown in FIG. 3, the pair of coated crimping pieces 26 b are erected vertically to the bottom plate portion 26 a, but this is not always necessary. For example, of the pair of coated crimping pieces 26b, the edge portion on the distal end side of the terminal 20 is formed in a shape inclined toward the proximal end side of the terminal 20 toward the distal end side in the standing direction of each coated crimped piece 26b. It is also possible.

  The intermediate connecting portion 25 is a portion that connects the coated crimping portion 26 and the core wire crimping portion 24. The intermediate connecting portion 25 includes a bottom plate portion 25a and a pair of side wall portions 25b that are erected on both sides of the bottom plate portion 25a and face each other.

  The core wire crimping portion 24 is a portion that is crimped to the exposed core wire portion 13a by being caulked. The core wire crimping portion 24 includes a bottom plate portion 24a and a pair of core wire crimping pieces 24b that are erected on both sides of the bottom plate portion 24a and face each other. In the present embodiment, the description will be made assuming that the direction in which the pair of core wire crimping pieces 24 b face each other is the width direction of the terminal 20. In addition, a description will be given assuming that the direction in which the pair of core wire crimping pieces 24 b is erected with respect to the bottom plate portion 24 a is the height direction of the terminal 20.

  The distal end side connecting portion 23 is a portion that connects the core wire crimping portion 24 and the counterpart connecting portion 28. The distal end side connecting portion 23 includes a bottom plate portion 23a and a pair of side wall portions 23b that are erected on both sides of the bottom plate portion 23a and face each other.

  Each bottom plate part 23a, 24a, 25a, 26a in the electric wire connection part 22 is formed in the shape connected as a plate shape as a whole. Moreover, the side wall part 23b, the core wire crimping piece 24b, the side wall part 25b, and the covering crimping piece 26b on one side in the width direction of the electric wire connection part 22 are formed in a shape that is continuous in a plate shape as a whole. Similarly, the side wall part 23b, the core wire crimping piece 24b, the side wall part 25b, and the covering crimping piece 26b on the other side in the width direction in the electric wire connection part 22 are also formed in a shape that is continuous in a plate shape as a whole. Further, the coated crimping piece 26b of the coated crimping portion 26 and the core crimping piece 24b of the core wire crimping portion 24 that are caulked (bent) portions with respect to the electric wire 12 are respectively connected to the intermediate coupling portion 25 and the distal end side coupling portion 23. It is formed longer in the height direction than the side walls 25b, 23b.

  In addition, the counterpart connection portion 28 is a portion (terminal connection portion) that is in direct contact with the counterpart conductor C as the counterpart electrical connection element and connected to the counterpart conductor C. Here, the counterpart connection portion 28 is a cylindrical portion in which a terminal insertion hole 28h, which is a hole into which the counterpart terminal C1 is fitted, is formed. In the present embodiment, the mating connection portion 28 is formed in a rectangular tube shape, and a contact piece 29 that contacts the mating terminal C1 and elastically deforms is provided inside.

  Here, an example in which the mating side connection portion 28 is formed in a cylindrical terminal shape (so-called female terminal shape) will be described. However, the mating side connection portion 28 has an elongated rod-like or elongated plate-like terminal shape (so-called male terminal). (Shape) may be formed. Moreover, the other party connection part 28 may be formed in the shape which can be bolted, ie, the shape by which the through-hole was formed in the flat main body part.

  The terminal 20 is connected to the end of the electric wire 12 as follows. That is, the end portion of the coating 14 is positioned between the pair of coated crimping pieces 26 b in the coated crimping portion 26, and the exposed core wire portion 13 a is positioned between the pair of core crimping pieces 24 b in the core wire crimping portion 24. The In this state, the coated crimping piece 26b of the coated crimping portion 26 is bent (caulked) toward the coating 14 (inside) on the bottom plate portion 26a. Furthermore, the core wire crimping piece 24b of the core wire crimping portion 24 is bent (caulked) to the exposed core wire portion 13a side (inner side) on the bottom plate portion 24a. Thereby, in the covering crimping portion 26, the bottom plate portion 26a and the two covering crimping pieces 26b are held in a state where they are crimped to the end portion of the covering 14, and in the core wire crimping portion 24, the bottom plate portion 24a and the two core wires are held. The crimping piece 24b is held in a state of being crimped to the exposed core part 13a. At this time, the front end side edge portion of the covering 14 is located at the position of the intermediate connecting portion 25, and a part thereof is exposed between the side wall portions 25 b. Similarly, the distal end side edge portion of the exposed core portion 13a is located at the position of the distal end side connecting portion 23, and a part thereof is exposed between the side wall portions 23b.

  Here, the core wire 13 (element wire) of the electric wire 12 and the terminal 20 are made of different kinds of metals. For example, the core wire 13 is made of aluminum or an aluminum alloy containing aluminum as a main component. On the other hand, the terminal 20 is made of copper or a copper alloy containing copper as a main component (brass, etc.), or tin (Sn) plating on these members, or silver (Ag), copper (Cu), bismuth on tin. This is a member plated with a tin alloy to which (Bi) or the like is added. Therefore, the dissimilar metal is in contact with the connecting portion between the core wire 13 and the terminal 20, and when an electrolyte such as salt water adheres to this portion, dissimilar metal contact corrosion may occur.

  Moreover, in the connection part of the terminal 20 and the electric wire 12, the exposed core part 13a is exposed outside at the following each part. That is, the base end portion of the exposed core wire portion 13a is exposed between the core wire crimp portion 24 and the coating crimp portion 26. Moreover, the front-end | tip part of the exposed core wire part 13a is exposed between the core wire crimping part 24 and the other party connection part 28. FIG. Further, a gap may be generated between the tip ends of the pair of core wire crimping pieces 24b in a state where the pair of core wire crimping pieces 24b of the core wire crimping portion 24 is caulked to the exposed core wire crimping portion 13a. In between, the intermediate part of the exposed core part 13a can be exposed.

  Therefore, the anticorrosive 18B in a fluidized state is between the proximal end side portion Q1 exposed to the covering crimping portion 26 with respect to the core wire crimping portion 24 in the exposed core wire portion 13a and the pair of core wire crimping pieces 24b of the core wire crimping portion 24. Of the exposed core wire portion 13a and the distal end side portion Q3 exposed on the opposite side of the coated crimp portion 26 to the core crimp portion 24a. Then, the anticorrosive 18B in a fluid state spreads on the surface of each of the portions Q1, Q2, and Q3 to form a coating, and the coating is cured (in this case, the viscosity is increased) to form the anticorrosion coating 18. Then, since each of those portions Q1, Q2, and Q3 is covered with the anticorrosion coating 18, even if the electrolytic solution adheres to the connection portion between the terminal 20 and the electric wire 12, the electrolytic solution remains on the exposed core portion 13a. Do not touch. For this reason, it will be suppressed that it will be in the state where electrolyte solution adhered to a dissimilar metal, and a dissimilar metal contact corrosion will be suppressed. The anticorrosion coating 18 is transparent or translucent, but this is not essential. Further, the anticorrosion coating 18 may be colored or colorless.

  But in order to suppress the enlargement of the connection part of the terminal 20 and the electric wire 12, and to suppress the usage-amount of the anticorrosive 18B, it is possible to supply a trace amount anticorrosive 18B as widely as possible. preferable. Therefore, here, when the fluidized anticorrosive 18B is supplied to each of the portions Q1 and Q2Q3, the fluidized anticorrosive 18B is supplied in a dotted manner in at least one of those portions. That is, the anticorrosive 18B in a fluid state is not continuously supplied, but is intermittently and partially supplied onto each of the parts Q1, Q2, and Q3. The anticorrosive agent 18B in a fluid state supplied in the form of dots spreads on the surface of the exposed core portion 13a according to its own viscosity, the wettability of the anticorrosive agent 18B with respect to the exposed core portion 13a, and the like. And the anticorrosive 18B supplied in the shape of a dot in a different location connects, and forms the continuous film. When the coating is cured (viscosity is increased), the anticorrosion coating 18 can be formed on portions Q1, Q2, and Q3 exposed from the connection portion of the exposed core portion 13a.

  In addition, the anticorrosive 18B may spread on the surface of the electric wire connection part 22 around Q1, Q2, and Q3. But it is preferable that the area | region where the anticorrosive 18B spreads on the surface of the electric wire connection part 22 is as small as possible.

  Here, it demonstrates as what uses the anticorrosive 18B which the magnitude | size change of a viscosity changes with temperature as the anticorrosive 18B. In particular, here, the description will be made assuming that the anticorrosive 18B whose viscosity is sufficiently lowered to be spread at about 137 degrees Celsius is used. In the graph showing the relationship between the temperature and the viscosity in the anticorrosive 18B, the slope of the curve between 120 degrees Celsius and 137 degrees Celsius is greater than the slope of the curve in an area less than 120 degrees Celsius or an area greater than 137 degrees Celsius. Is also big.

  As described above, when the anticorrosive agent 18B that causes a change in the magnitude of viscosity or a phase change between the solid and liquid phases is used as the anticorrosive agent 18B, the anticorrosion during the supply compared to the photocurable anticorrosive 18B or the like. The agent 18B tends to cure or increase in viscosity. In particular, when the anticorrosive agent 18B is supplied in the form of dots as described above, the temperature of the anticorrosive agent 18B is likely to change, and thus the anticorrosive agent 18B is likely to be cured or increased in viscosity during supply. And if the anticorrosive 18B hardens | cures or a viscosity rise during supply, it will become difficult to form the continuous coating by connecting the anticorrosive 18B supplied in the point form in a different location. Therefore, the anticorrosive agent supply apparatus according to the present embodiment makes it possible to obtain the terminal-attached electric wire 10 on which the anticorrosion coating 18 is well formed by making the anticorrosive agent 18B difficult to cure or increase in viscosity during supply. It has become.

Next, the anticorrosive agent supply apparatus will be described with reference to FIGS. FIG. 4 is a schematic perspective view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 5 is a schematic side view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 6 is a partial schematic plan view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 7 is an explanatory diagram showing the supply unit 40 and the detection unit 100. FIG. 8 is a perspective view showing a state in which a part of the suction mechanism 70 is disassembled.

  The anticorrosive agent supply device 30 includes a first mechanism 32, a second mechanism 50, and an electric wire transport unit 90. Furthermore, the anticorrosive agent supply device 30 includes a control unit 110 that performs operation control of each of the first mechanism 32, the second mechanism 50, and the electric wire conveyance unit 90.

  Below, in the anticorrosive agent supply apparatus 30, the direction where the some electric wire 10 with a terminal is conveyed by the electric wire conveyance part 90 is set to x-axis direction. At this time, the electric wire with terminal 10 extends in a direction orthogonal to the x-axis direction, and this direction is defined as a y-axis direction. A direction orthogonal to the x-axis direction and the y-axis direction is taken as a z-axis direction. Here, the z-axis direction is a direction along the vertical direction.

  The first mechanism 32 includes a conveyance chuck 34, an imaging unit 38, and a supply unit 40, which are movable together. Here, the 1st mechanism 32 contains the y-axis direction moving mechanism 33 provided so that the said each part was integrally movable to a y-axis direction. Accordingly, the transport chuck portion 34, the imaging portion 38, and the supply portion 40 are connected to the y-axis direction moving mechanism 33. The conveyance chuck unit 34, the imaging unit 38, and the supply unit 40 are arranged in this order along the y-axis direction.

  The conveyance chuck portion 34 is a portion that transfers the electric wire 12 between the electric wire conveyance portion 90 and an electric wire setting portion 52 described later. Here, the conveyance chuck portion 34 includes a chuck portion 35 and a z-axis direction moving mechanism 36. A z-axis direction moving mechanism 36 is connected to the y-axis direction moving mechanism 33, and a chuck portion 35 is provided at the tip of the z-axis direction moving mechanism 36.

  Here, the z-axis direction moving mechanism 36 is formed so that the chuck portion 35 can be moved to three different positions along the z-axis direction. The first position among the three positions is a standard position of the transport chuck section 34. When the transport chuck section 34 does not operate, the chuck section 35 is positioned at the first position. Also, when the y-axis direction moving mechanism 33 operates, the chuck portion 35 is located at the first position, and the y-axis direction moving mechanism 33 prevents the moving chuck portion 35 from interfering with other members. Yes. Of the three positions, the second position is a position when the chuck portion 35 delivers the electric wire 12 to and from a covering chuck portion 58 of the electric wire setting portion 52 described later. The third position among the three positions is a position when the chuck unit 35 delivers the electric wire 12 to and from the electric wire transport unit 90. Here, the first position, the second position, and the third position are set in this order from the positive side to the negative side along the z-axis direction. That is, here, the electric wire 12 set in the electric wire setting unit 52 is positioned higher in the z-axis direction than the electric wire 12 being conveyed by the electric wire conveyance unit 90.

  Here, the chuck portion 35 includes a pair of sandwiching claws 35a and a drive unit (not shown) that opens and closes the pair of sandwiching claws 35a, and is formed so that the electric wire 12 can be chucked. The pair of sandwiching claws 35 a are formed in a shape in which an intermediate portion is recessed, and the wire 12 can be sandwiched at two different locations along the extending direction of the wire 12. Thereby, rotation of the electric wire 12 when the electric wire 12 is chucked by the chuck portion 35 is suppressed.

  The electric wire 12 is transferred between the electric wire conveyance part 90 or the electric wire setting part 52 as follows using the conveyance chuck part 34. That is, the y-axis direction moving mechanism 33 moves the conveyance chuck unit 34 along the y-axis direction to a position corresponding to the electric wire conveyance unit 90 or the electric wire set unit 52. In this state, the z-axis direction moving mechanism 36 moves the chuck portion 35 to a position corresponding to the electric wire 12 along the z-axis direction. In this state, the chuck unit 35 is driven to open and close, so that the electric wire 12 is delivered to and from the electric wire transport unit 90 or the electric wire set unit 52.

  The imaging part 38 is provided so that the connection part of the electric wire 10 with a terminal can be imaged. Here, the imaging unit 38 is an imaging camera configured by a CCD camera or the like. As the imaging unit 38, a two-dimensional camera may be used, or a stereo camera may be used. Here, the former example will be described. Here, the imaging unit 38 moves to a position corresponding to the wire setting unit 52 along the y-axis direction by the y-axis direction moving mechanism 33. In this state, the imaging unit 38 images the terminal-attached electric wire 10 set in the electric wire setting unit 52, whereby the connection portion is imaged.

  The supply part 40 is provided so that the anticorrosive 18B can be supplied. The supply unit 40 includes a discharge mechanism 41 and a discharge mechanism moving mechanism 46. Further, here, a detection unit 100 and a supply unit heating unit 82 are provided around the supply unit 40.

  The discharge mechanism 41 is a part that stores the anticorrosive 18B and discharges the stored anticorrosive 18B. The discharge mechanism 41 includes a discharge unit 42 and a storage unit 44.

  The discharge part 42 is a part from which the anticorrosive 18B is discharged. Here, a description will be given assuming that a dispenser is provided as the discharge unit 42. Here, the dispenser can discharge a certain amount of the anticorrosive 18B with pressurization by air. In particular, here, the dispenser can eject the anticorrosive 18B drop by drop. The size of the discharged anticorrosive agent 18B is not particularly limited, but is preferably smaller than the width of the terminal 20. The size of the droplet of the anticorrosive agent 18B to be discharged is determined by, for example, the viscosity of the anticorrosive agent 18B, the size of the opening of the discharge portion 42, the degree of pressurization, and the like.

  The accommodating portion 44 is a portion that is formed in a cylindrical shape and accommodates the anticorrosive agent 18 </ b> B that is discharged by the discharge portion 42. The accommodating portion 44 and the discharge portion 42 are communicated with each other through a communication passage 45. Accordingly, here, the anticorrosive 18B accommodated in the accommodating portion 44 is sent to the discharge portion 42 through the communication passage 45, and is pressurized and discharged by the discharge portion 42.

  The discharge mechanism moving mechanism 46 is provided so that the discharge mechanism 41 can be moved. Here, the discharge mechanism moving mechanism 46 includes an x-axis direction discharge mechanism moving mechanism that moves the discharge mechanism 41 along the x-axis direction, and a y-axis direction discharge mechanism movement mechanism that moves the discharge mechanism 41 along the y-axis direction. Including. The discharge mechanism moving mechanism 46 adjusts the position of the discharge position when discharging the anticorrosive 18B in a dot shape. Therefore, the discharge mechanism moving mechanism 46 only needs to be able to move the discharge mechanism 41 within a narrow range that can cover the connection portion. For example, the movable range of the x-axis direction discharge mechanism moving mechanism may be approximately the same as the width dimension of the terminal 20. Further, for example, the movable range of the y-axis direction discharge mechanism moving mechanism may be approximately the same as the dimension from the distal end side connecting portion 23 to the cover crimping portion 26 in the terminal 20, compared with the y-axis direction moving mechanism 33. The movable range is narrow.

  The detection part 100 is provided so that the anticorrosive 18B discharged by the discharge part 42 can be detected. In the example illustrated in FIG. 7, the detection unit 100 includes an optical sensor having a light projecting unit 102 and a light receiving unit 104.

It is preferable. Thereby, before the anticorrosive 18B spreads sufficiently, it can suppress that the viscosity of the anticorrosive 18B rises and the situation where the anticorrosive 18B cannot fully spread arises. For example, the desired ultimate temperature of the terminal 20 is set to 150 degrees Celsius to 170 degrees Celsius. However, the desired ultimate temperature of the terminal 20 is not limited to the above. The desired ultimate temperature of the terminal 20 is a value set experimentally and empirically based on the temperature of the anticorrosive 18B immediately before supply, and the thermal conductivity and melting point of each part of the anticorrosive 18B, the terminal 20, and the wire 12.

In addition, here, the suction part 72 sucks the excess of the anticorrosive 18B between the covering presser part 64 and the support part 68 along the extending direction of the terminal-attached electric wire 10. Here, the suction portion 72 includes a suction body portion 73 including a suction port 73a and a suction contact portion 77 provided in the suction port 73a.

  For example, the suction main body 73 is formed in a cylindrical shape and is open at both ends. One of the openings at both ends of the suction body 73 forms a suction port 73a. The suction port 73a faces upward. Since the suction main body 73 is located below the connection portion, the suction port 73a faces the connection portion. Therefore, here, the suction part 72 sucks the surplus of the anticorrosive 18B from below the connection part. More specifically, the suction main body portion 73 includes a first main body portion 74a and a second main body portion 74b.

  The first main body portion 74a is located on the connection portion side with respect to the second main body portion 74b, that is, on the positive side in the z-axis direction here. The first main body 74a is formed in a rectangular parallelepiped shape. The first main body portion 74a is formed with a through hole 74ah that penetrates a pair of main surfaces facing each other. The axial center direction of the through hole 74ah is along the z-axis direction. The through hole 74ah is formed in an H shape in plan view (viewed from the positive side in the z-axis direction). One opening (here, facing the positive side in the z-axis direction) of the through hole 74ah forms the suction port 73a. A pair of leg portions 77b (to be described later) of the suction contact portion 77 are accommodated in a pair of sides of the H-shaped parallel to each other. That is, the first main body portion 74 a accommodates a part of the suction contact portion 77.

  In addition, a suction drive unit 75 is connected to the first main body 74a. The suction drive unit 75 is connected to the first main body 74a through the pipe 76. At this time, the pipe 76 is connected to an opening 74ab formed on the side surface of the first main body 74a. The side opening 74ab communicates with the through hole 74ah of the first main body 74a.

  The second main body portion 74b is located on the opposite side to the connection portion with respect to the first main body portion 74a, that is, on the negative side in the z-axis direction here. The 2nd main-body part 74a is formed in the shape where the rectangular parallelepiped of two different magnitude | sizes continued on the side surface. In each rectangular parallelepiped of the second main body portion 74b, through holes 74bg and 74bh penetrating a pair of main surfaces facing each other are formed. The axial center direction of the through holes 74bg and 74bh is along the z-axis direction. The through holes 74bg and 74bh are formed in a circular shape in plan view.

  The through hole 74bh communicates with the through hole 74ah. At this time, the through hole 74bh is formed to be slightly smaller than the through hole 74ah, and is formed so as not to overlap the H-shaped pair of side portions of the through hole 74ah that are parallel to each other. Therefore, here, when the through holes 74ah and 74bh are viewed from the positive side in the z-axis direction, the peripheral portion of the through hole 74bh can be confirmed through a pair of mutually parallel sides of the H shape of the through hole 74ah. it can. Accordingly, the pair of leg portions 77b of the suction contact portion 77 accommodated in the pair of H-shaped parallel sides of the through hole 74ah is supported by the peripheral portion of the through hole 74bh of the second main body portion 74b. Is done. Further, a suction main body heating section 86 described later is accommodated in the through hole 74bg.

  The suction drive unit 75 sends compressed air toward the first main body 74a. The compressed air is discharged from the pipe 76 toward the opening 74ac facing downward in the opening at both ends of the through hole 74ah of the first main body 74a. Due to the influence of the flow of compressed air, the surplus of the anticorrosive 18B in the vicinity of the suction port 73a is sucked into the first main body 74a. The surplus of the anticorrosive 18B sucked into the first main body 74a from the suction port 73a is discharged downward from the opening 74ac facing downward. The surplus of the anticorrosive 18B discharged from the opening 74ac passes through the through hole 74bg of the second main body 74b and is discharged downward. In addition, the collection | recovery part 120 which collect | recovers the excess of the discharged | emitted anticorrosive 18B is good below the 2nd main-body part 74b. The surplus of the anticorrosive 18B collected by the collection unit 120 may be discarded or reused.

  The suction body part 73 is heated by the suction body part heating part 86. Here, a heater that abuts on and heats the suction main body 73 as the suction main body heating section 86 is provided. For example, a rod-shaped heater is stored in the through hole 74bg of the second main body portion 74b. The suction body heating unit 86 is an example of a heat mechanism that heats the suction port 73a. When the suction main body 73 is heated by the suction main body heating section 86, the surplus of the anticorrosive 18B sucked into the suction main body 73 becomes difficult to stay on the inner peripheral surface of the suction main body 73, and the lower part It becomes easy to discharge downward from the opening that faces. But the suction main-body part heating part 86 does not need to be provided.

  The suction contact portion 77 is provided in the suction port 73a. The suction contact portion 77 can contact the connection portion when sucking the surplus of the anticorrosive 18B. Here, the suction contact portion 77 contacts the lower surface of the wire connection portion 22, that is, the lower surface of at least a part of the bottom plate portions 23a, 24a, 25a, and 26a. Particularly, here, the suction contact portion 77 is provided so as to contact a portion including the lower surface of the bottom plate portion 24a. The suction contact portion 77 is formed in a leaf spring shape. The suction contact portion 77 is formed in a curved surface shape in which a part of a plane protrudes in the z-axis direction. The suction contact portion 77 is provided so as to be elastically deformable in the z-axis direction. The suction contact portion 77 is provided above the suction port 73a so as to protrude in the z-axis direction with respect to the suction port 73a. More specifically, the suction contact portion 77 includes a contact portion 77a and a pair of leg portions 77b. The suction contact portion 77 is formed with a through hole 77h.

  The contact portion 77a is formed in a curved surface shape in which a part of the plane protrudes in the z-axis direction. Here, the contact portion 77a is formed in a rectangular flat plate shape, and the intermediate portion protrudes toward the positive side in the z-axis direction while curving from both edges toward the intermediate portion. The contact portion 77a is provided to be elastically deformable in the z-axis direction. In a state where the pair of leg portions 77b is housed in the through hole 74ah, the contact portion 77a projects in the z-axis direction with respect to the suction port 73a.

  The pair of leg portions 77b are formed in a rectangular flat plate shape. The pair of leg portions extend in parallel with each other from both edges of the contact portion 77a toward the negative side in the z-axis direction. Here, the pair of leg portions 77b are located apart in the y-axis direction. For this reason, the contact portion 77a extends while being curved along the y-axis direction. As a result, the portion of the contact portion 77a that protrudes most in the z-axis direction is reliably contacted by the terminal 20. In addition, a recess 77c is formed in one of the pair of leg portions 77b. The recess 77c is recessed from the edge on the side opposite to the side continuous with the contact portion 77a toward the edge on the side continuous with the contact portion 77a. The concave portion 77c is provided in order to prevent the leg portion 77b from closing the opening 74ab when the leg portion 77b is stored inside the surface of the first main body portion 74a where the opening 74ab is formed. is there.

  The through hole 77h is formed in the contact portion 77a. In particular, here, the through hole 77h is formed in a region including a portion of the contact portion 77a that protrudes most in the z-axis direction. The through hole 77h is formed in a size that allows the anticorrosive 18B to pass therethrough. By forming the through hole 77h in the contact portion 77a, when the surplus of the anticorrosive 18B is transmitted through the contact portion 77a, it is difficult to stay in the contact portion 77a. But the through-hole 77h does not need to be formed.

  The suction body part 73 and the suction contact part 77 heated by the suction body part heating part 86 are preferably formed of a member having good thermal conductivity, such as metal.

  The suction part moving mechanism 78 is composed of, for example, a cylinder or a linear motor, and reciprocates the suction part 72 along the z-axis direction. In the example shown in FIG. 8, the suction part moving mechanism 78 is connected to the second main body part 74b and reciprocates along the z-axis direction. For example, when the suction part moving mechanism 78 is not driven, the suction part 72 is located at a position where the suction contact part 77 is below the terminal 20 and does not contact the terminal 20. Then, when the surplus of the anticorrosive 18B supplied to the connection portion is sucked, the suction portion 72 is driven to the position where the suction contact portion 77 contacts the lower side of the terminal 20 by driving the suction portion moving mechanism 78. To position. Therefore, here, the suction part moving mechanism 78 reciprocates the suction part 72 between the two points. That is, the suction part moving mechanism 78 is an example of a reciprocating mechanism that reciprocates the suction contact part 77 between a position where the suction contact part 77 is in contact with the connection portion and a retracted position.

The set bar 93 is conveyed in the x-axis direction such that the longitudinal direction of the support block 93a is along the x-axis direction. Each pair of support claws 93 b is formed in a shape that can be received in the recess of the chuck portion 35 in a state where the longitudinal direction of the support block 93 a is along the x-axis direction. Therefore, the chuck portion 35 can sandwich the front and rear portions along the y-axis direction with respect to the portion sandwiched between the pair of support claws 93b. The support claw 93b grips the electric wire 12 by an elastic force. More specifically, the support claw 93b is provided to be openable and closable by pressing the electric wire 12 along a standing direction (here, the z-axis direction) with respect to the support block 93a.

One end and the other end of the link mechanism 94a are provided at positions separated from each other in the z-axis direction, extend from the one end and the other end in the same direction along the x-axis direction, and are bent at an intermediate portion in the extending direction. Therefore, the link mechanism 94a has a U shape or a J shape when viewed from the y-axis direction. The set bar 93 is conveyed in the x-axis direction with respect to the fixed frame by changing the distance from one end (the other end) of the link mechanism 94a to the bent portion. It is conceivable that the set bar 93 is detachably provided on a member that supports the set bar 93, for example. Thereby, the electric wire 12 can be supplied or discharged together with the set bar 93 to the electric wire conveying unit 90. The electric wire conveyance part 90 is good to be able to send the set bar 93 by the integral multiple of the space | interval of a pair of support nail | claw 93b.

It is also conceivable that a temperature sensor capable of measuring the temperature of the terminal 20 is provided. In this case, the operations of the terminal heating unit 84 and the terminal chuck unit 54 may be controlled based on the measured temperature of the temperature sensor.

  Moreover, the set state detection part 106 which can detect that the electric wire 10 with a terminal was set to the electric wire set part 52 may be provided. The set state detection part 106 is provided in the rear end side support part 108 which supports the part extended back from the electric wire set part 52 among the electric wires 10 with a terminal, for example. In the example illustrated in FIG. 4, the set state detection unit 106 includes an optical sensor including a light projecting unit and a light receiving unit, and determines whether or not the terminal-attached electric wire 10 supported by the rear end side support unit 108 exists. Detect. In this case, when the set state detection part 106 detects the electric wire 10 with a terminal, the control part 110 can consider giving the operation command which concerns on supply of the anticorrosive 18B to each part.

<Manufacturing method>
Next, the manufacturing method of the electric wire 10 with a terminal using the said anticorrosive agent supply apparatus 30 is demonstrated, referring FIG. 9 thru | or FIG. FIG. 9 is a diagram for explaining the flow of the manufacturing process of the terminal-attached electric wire 10 using the anticorrosive agent supply device 30. 10, FIG. 11 and FIGS. 14 to 18 are explanatory views showing a manufacturing process of the terminal-attached electric wire 10. FIG. 12 is an explanatory diagram illustrating an example of a supply position of the anticorrosive agent 18 </ b> B with respect to the terminal-attached electric wire 10. FIG. 13 is an explanatory diagram illustrating another example of the supply position of the anticorrosive agent 18 </ b> B with respect to the terminal-attached electric wire 10.

  First, as step S01, the electric wire 12 is supplied. Here, the electric wire conveyance part 90 conveys the electric wire 12 to be supplied to a predetermined position along the x-axis direction. In this state, as shown in FIG. 10, the electric wire 12 supported by the electric wire conveying portion 90 by the conveying chuck portion 34 is conveyed and set to the electric wire setting portion 52.

  More specifically, by driving the y-axis direction moving mechanism 33, the conveyance chuck portion 34 is positioned above the support claw 93 b of the set bar 93 of the electric wire conveyance unit 90. In this state, by driving the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit, the transfer chuck unit 34 receives the wire 12 from the wire transfer unit 90. Next, by driving the y-axis direction moving mechanism 33, the conveyance chuck portion 34 that has received the electric wire 12 from the electric wire conveyance portion 90 is positioned above the covering chuck portion 58. In this state, by driving the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit, the electric wire 12 is transferred from the transfer chuck unit 34 to the covering chuck unit 58. At this time, the terminal 20 is supported by the support portion 68. Further, before this delivery operation, more specifically, immediately before the conveying chuck portion 34 is positioned above the covering chuck portion 58, the terminal pressing portion 61 is rotated so as to be temporarily located at a position where it does not interfere with delivery. Move. More specifically, after or during the delivery operation, the z-axis direction moving mechanism 36 is driven so that the sandwiching claw 58a of the covering chuck portion 58 is positioned at a position where the sandwiching claw 35a of the chuck portion 35 fits in the recess. Immediately after the chuck portion 35 is moved, the terminal 20 is rotated so as to return to a position where the terminal 20 can be pressed.

  When the covering chuck portion 58 chucks the covering 14, the terminal chuck portion 54 chucks the terminal 20. Here, the mating side connection portion chuck portion 55 chucks the mating side connection portion 28, and the core wire crimping portion 24 chuck portion chucks the core wire crimping portion 24. Here, it is described that the wire connection portion chuck portion 55 chucks the wire connection portion 22 after the counterpart connection portion chuck portion 55 chucks the counterpart connection portion 28. However, the order of chucking is as described above. The reverse may be sufficient, and simultaneous may be sufficient. The terminal chuck 54 is heated to a predetermined temperature by the terminal heating unit 84 before chucking the terminal 20.

  As described above, when the electric wire 12 is set in the electric wire setting unit 52, the supply position of the anticorrosive 18B is detected as step S02. More specifically, here, as shown in FIG. 11, by driving the y-axis direction moving mechanism 33, the imaging unit 38 is positioned above the connection part, and then the connection part is imaged by the imaging unit 38. To do. Then, the supply position is detected from the imaging data of the imaging unit 38. For example, it is considered that the dimensional tolerance in the shape of the terminal 20 is relatively small as compared with the dimensional tolerance of the crimping position of the electric wire 12 with respect to the terminal 20 or the variation tolerance of the setting position of the electric wire 12 with respect to the electric wire set portion 52. For this reason, for example, the predetermined position of the terminal 20 is determined from the obtained imaging data, and the anticorrosive 18B is supplied in accordance with a predetermined supply program with reference to the determined predetermined position, so that the anticorrosive is relatively accurate. 18B can be supplied.

  At this time, it is also conceivable to change the conditions such as the supply range or supply amount of the anticorrosive 18B from the obtained imaging data. For example, the position of the edge part of the coating | cover 14 along the extension direction of the electric wire 12 is calculated | required from the acquired imaging data. And according to the position of the edge part of the coating | coated 14, the supply range of the anticorrosive 18B is changed as shown in FIG. 12 or FIG. In the example shown in FIGS. 12 and 13, the position where the droplet of the anticorrosive 18 </ b> B is supplied is indicated by a black dot. More specifically, comparing FIG. 12 with FIG. 13, in the example shown in FIG. 12, the edge portion of the coating 14 is in the rear end side (along the y-axis direction) along the extending direction of the electric wire 12 with respect to the terminal 20. In the example shown in FIG. 13, the edge of the coating 14 is on the tip side (the positive side along the y-axis direction) along the extending direction of the electric wire 12 with respect to the terminal 20. To position. Even when there is such a difference in the position of the edge of the coating 14, the anticorrosion agent 18 </ b> B only up to a position a predetermined distance away from the edge of the coating 14 to the rear end side regardless of the position of the edge of the coating 14 with respect to the terminal 20. If not set, the range in which the anticorrosive 18B is supplied changes as shown in FIGS.

  Here, the intention of changing the supply range of the anticorrosive 18B as described above is as follows. That is, since the coating 14 is made of, for example, a resin or the like, it is inferior in thermal conductivity as compared with the core wire 13 and the terminal 20 that are made of a metal. For this reason, when the range of the anticorrosive agent 18 </ b> B supplied to the coating 14 is wide, it takes time to heat the coating 14 corresponding to the range via the terminal chuck portion 54. Moreover, when the coating 14 is not sufficiently heated, the anticorrosive 18B may not be sufficiently spread and collected, and the thickness of the terminal-attached electric wire 10 may be increased. On the other hand, from the viewpoint of the anticorrosive property, the necessity of supplying the anticorrosive agent 18B from the front edge of the coating 14 to a position far along the extending direction is not so high. Therefore, the anticorrosive 18B is supplied in accordance with the position of the coating 14 with respect to the terminal 20 in order to obtain the terminal-equipped electric wire 10 that has the necessary anticorrosion properties and does not become so thick even if the anticorrosion coating 18 is formed. The range to be changed is changed.

  In addition, the supply conditions of the anticorrosive 18B changed from the obtained imaging data are not restricted to what was mentioned above.

  For example, even when the position of the edge of the coating 14 with respect to the terminal 20 is different, when the same amount of the anticorrosive 18B is supplied to the same position, it is conceivable to change the heating time by the terminal heating unit 84. Specifically, the coating 14 is inferior in thermal conductivity as compared with the terminal 20 and the core wire 13 as described above. Therefore, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is large, the heating time by the terminal heating unit 84 is lengthened. Conversely, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is small, the heating for the terminal is performed. It is conceivable to shorten the heating time by the part 84. Thereby, the anticorrosive agent 18B supplied to the coating 14 is surely easily spread to a desired range before being cured.

  For example, even when the position of the edge of the coating 14 with respect to the terminal 20 is different, when the anticorrosive 18B is supplied to the same position, it is conceivable to reduce the anticorrosive 18B supplied to the coating 14. Specifically, the coating 14 is inferior in thermal conductivity as compared with the terminal 20 and the core wire 13 as described above. Therefore, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is large, it is conceivable to reduce the amount of one drop of the anticorrosive 18B supplied to the coating 14. Thereby, the anticorrosive agent 18B supplied to the coating 14 is surely easily spread to a desired range before being cured. In this case, in the case where the ratio of the coating 14 in the supply range of the anticorrosive 18B is large and the case where the ratio is small, it is considered that the supply amount of the anticorrosive 18B when viewed from the whole terminal-attached electric wire is increased. .

  As shown in FIG. 14, when the terminal chuck 54 chucks the terminal 20, the temperature of the terminal 20 is raised as the next step S03. Here, the terminal 20 is heated for a predetermined period of time with the terminal chuck 54 chucking the terminal 20 including the time when the imaging unit 38 images the connection portion. The heating time of the terminal 20, that is, the chucking time of the terminal 20 by the terminal chuck portion 54 is comprehensively determined and determined based on experimental and empirical viewpoints.

  When the temperature of the terminal 20 is sufficiently raised, the anticorrosive 18B is supplied as the next step S04. More specifically, as shown in FIG. 15, the y-axis direction moving mechanism 33 is driven to position the supply unit 40 above the connection portion. At this time, the supply unit 40 may be positioned at a position corresponding to the supply position detected in step S02. And the anticorrosive 18B is discharged by the discharge mechanism 41, and is supplied to a connection part. At this time, the discharge mechanism moving mechanism 46 is driven to supply the anticorrosive 18B drop by drop to a preset position, here a position indicated by a black dot in FIGS. At this time, the ejection mechanism 41 moves along the trajectory corresponding to the line connecting the black dots in FIGS. 12 and 13 in each part of Q1, Q2, and Q3 by driving the ejection mechanism moving mechanism 46. In the example shown in FIG. 12 and FIG. 13, after discharging the anticorrosive 18B to the discharge position along this direction while moving from one end side to the other end side along the x-axis direction, it moves in the y-axis direction, The anticorrosive 18B is discharged to a discharge position along this direction while moving from the other end side to the one end side along the x-axis direction. However, the movement of the discharge mechanism 41 by the discharge mechanism moving mechanism 46 is not limited to the above. For example, it may move along the y-axis direction while moving from one end side to the other end side along the x-axis direction, or always move from one end side to the other end along the x-axis direction. You may move toward the side.

  Here, before the supply of the anticorrosive 18B is started, the wire connection portion chuck portion 56 is opened as shown in FIG. 16, and the state where the connection portion is chucked is eliminated. Thereby, it is suppressed that the electric wire connection part chuck | zipper part 56 obstructs supply operation | work, and that the anticorrosive 18B supplied to the circumference | surroundings of the electric wire connection part 22 adheres to the electric wire connection part chuck | zipper part 56. Further, the mating connector chuck 55 maintains the chucked mating connector 28 during the supply of the anticorrosive 18B. As a result, the degree of temperature drop of the terminal 20 due to changes over time and the supply of the anticorrosive agent 18B is reduced, and the supplied anticorrosive agent 18B is less likely to spread.

  When the supply of the anticorrosive 18B is completed, the supply state is inspected as the next step S05. Here, each drop is detected by the detection unit 100 when the anticorrosive 18B is supplied. Therefore, data that associates the detection result of the detection unit 100 with the position of the discharge mechanism 41 with respect to the connection portion at that time is formed, and this is compared with a predetermined supply position of the anticorrosive 18B that is set in advance. It is inspected whether the anticorrosive 18B has been supplied to the position.

  In addition to the above inspection, an image inspection may be performed. In this case, as illustrated in FIG. 17, the connection portion is imaged by the imaging unit 38 in a state where the y-axis moving mechanism is driven and the imaging unit 38 is positioned above the connection portion. And the supply state of anticorrosive 18B is test | inspected from the acquired imaging data.

  When the inspection of the supply state is completed, the surplus of the anticorrosive 18B is sucked as the next step S06. Here, first, as shown in FIG. 18, the covering presser piece moving mechanism 66 is driven and the covering 14 is pressed by the covering presser piece 65. Then, the suction part moving mechanism 78 is driven to bring the suction part 72 closer to the wire connection part 22. Here, as shown in FIG. 17, the suction contact portion 77 is brought into contact with the lower surface of the wire connection portion 22. Here, since the suction contact portion 77 is formed in a leaf spring shape, it can absorb the difference in the size of the connecting portion of the terminal-attached electric wire 10 and can be contacted in an elastically deformed state. The contact state can be maintained more reliably. Then, the suction drive part 75 is driven and the excess part of the anticorrosive 18B which exists in a connection part is attracted | sucked. However, the driving of the suction driving unit 75 may be started before or during the driving of the suction unit moving mechanism 78. At this time, since the suction part 72 is heated by the suction part heating part 86, the anticorrosive 18B is hard to be hardened during suction. However, the step S05 may be performed before the supply state inspection or in parallel with the inspection as long as the supply is completed.

  When the suction of the surplus is completed, the electric wire 12 is discharged from the electric wire setting unit 52 as the next step S07. More specifically, the covering presser piece 65 and the suction part 72 are retracted, and the mating connection part chuck part 55 is opened. Then, the y-axis direction moving mechanism 33 is driven to position the transport chuck portion 34 above the covering chuck portion 58. In this state, the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit are driven to deliver the electric wire 12 from the covering chuck unit 58 to the conveying chuck unit 34. Before and after this delivery operation, the terminal presser 61 also rotates so as not to obstruct the delivery operation, as in step S01.

  When the conveyance chuck unit 34 receives the electric wire 12, the y-axis moving mechanism is driven to position the conveyance chuck unit 34 above the support claw 93 b of the set bar 93. In this state, the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit are driven to deliver the electric wire 12 from the transfer chuck unit 34 to the support claw 93b. Thereby, it will be in the state where the electric wire 12 was discharged | emitted from the electric wire set part 52 to the electric wire conveyance part 90. FIG.

  If the electric wire 12 is discharged | emitted from the electric wire setting part 52 to the electric wire conveyance part 90, the electric wire 12 of the electric wire conveyance part 90 will be sent as next step S08. For example, the set bar 93 is sent by an interval between two adjacent pairs of support claws 93b. As a result, the next electric wire 12 to be processed is supplied to a position where it can be chucked by the conveyance chuck portion 34.

  Thereafter, returning to step S01, by repeating steps S01 to S08, the anticorrosive agent 18B is sequentially supplied to the plurality of electric wires with terminals 10 supported by the set bar 93, and the anticorrosive coating 18 is formed. The electric wire 10 is manufactured continuously. Here, the anticorrosive agent 18 </ b> B supplied to the connection portion is naturally cooled to increase the viscosity, thereby forming the anticorrosion coating 18. But the anticorrosive 18B supplied to the connection part may be cooled by cooling means, such as air cooling or water cooling. In this case, the cooling means may or may not be incorporated in the anticorrosive supply device 30.

  In addition, the operation | work which discharges the electric wire 10 with a terminal in which the anticorrosion coating 18 was formed from the anticorrosive agent supply apparatus 30, and the operation | work which supplies the electric wire with a terminal 10 to which the anticorrosive agent 18B is not supplied to the anticorrosive agent supply apparatus 30 are The anticorrosive agent 18B may be supplied during the supply operation, or may be performed collectively after supplying the anticorrosive agent 18B to all the electric wires with terminals 10 supported by the set bar 93.

  According to the anticorrosive agent supply apparatus 30 configured as described above, since the surplus portion of the anticorrosive agent 18B is sucked and removed by the suction mechanism 70, the surplus portion of the anticorrosive agent 18B can be easily removed. Thereby, it can suppress more easily that the connection part of the electric wire 12 and the terminal 20 in the electric wire 10 with a terminal becomes thick.

  In addition, the suction port 73a of the suction mechanism 70 is provided with a suction contact portion 77 that can contact the connection portion when suctioning the surplus of the anticorrosive agent 18B. The surplus can be sucked more reliably.

  The suction mechanism 70 further includes a suction part moving mechanism 78 that reciprocates between the position where the suction contact part 77 is in contact with the connection part and the retracted position, so that the suction mechanism 70 supplies the anticorrosive agent. Can be prevented from getting in the way.

  In addition, the suction contact portion 77 is in contact with the connection portion from below in a state where the exposed wire 10 is supported in such a manner that the exposed core portion 13a in the connection portion faces upward. 77 can abut on the surface without the core wire 13 with respect to the connecting portion. Thereby, inhalation to the required anticorrosive 18B can be suppressed. Moreover, the surplus part tends to flow downward by its own weight. Even in this case, by sucking from below, it is possible to suck without surplus as much as possible.

  Further, since the suction contact portion 77 is formed in a leaf spring shape, it is easy to maintain the contact state with a simple configuration. In addition, the difference in size of the terminal-attached electric wire 10 can be easily absorbed by forming the suction contact portion 77 in a leaf spring shape.

  Moreover, since the through hole 77h through which the anticorrosive agent 18B can pass is formed in the suction contact portion 77, the anticorrosive agent 18B can be prevented from accumulating in the suction contact portion 77.

  Further, when the suction mechanism 70 sucks the surplus of the anticorrosive 18B, the support portion 68 that supports the terminal-attached electric wire 10 from below, and when the suction mechanism 70 sucks the surplus of the anticorrosive 18B, the terminal-attached electric wire 10 is supported. Since the press part 60 which presses from above is further provided, the position shift at the time of suction can be suppressed.

  The holding portion 60 includes a covering holding portion 64 that holds the covering 14 of the electric wire 12 from above, and a terminal holding portion 61 that holds the terminal 20 from above. The suction mechanism 70 extends in the extending direction of the electric wire 10 with terminal 10. Since the surplus part of the anticorrosive 18B is sucked between the covering presser part 64 and the terminal presser part 61, the positional deviation at the time of suction can be more reliably suppressed.

  Moreover, since the suction body 73 heating part 86 for heating the suction port 73a is further provided, even when the anticorrosive 18B is an anticorrosive that causes a change in the magnitude of the viscosity depending on the temperature, the anticorrosive is cured during the removal. Can be suppressed.

{Modifications}

In the anticorrosive agent supply apparatus 130 according to the modification, two processing units 131 having the first mechanism 32 and the second mechanism 50 are provided for one electric wire transport unit 90. Thus, by providing the some process part 131 with respect to the one electric wire conveyance part 90, the production efficiency in the one anticorrosive agent supply apparatus 130 can be improved. In addition, when the two process parts 131 are provided with respect to one electric wire conveyance part 90, as the method of sending the electric wire 12 by the electric wire conveyance part 90, the following two types can be considered, for example. The first case is a case where the terminal-attached electric wires 10 processed by the two processing units 131 are alternately arranged along the conveyance direction of the electric wire conveyance unit 90. In this case, the set bar 93 may be fed by a size twice as large as the interval between the adjacent support claws 93b in one feed. Secondly, the terminal-attached electric wires 10 to be processed by one processing unit 131 are collected on one side along the conveyance direction of the electric wire conveyance unit 90 and the other side along the conveyance direction of the electric wire conveyance unit 90 is the other. This is a case where the terminal-attached electric wires 10 to be processed by the processed portion 131 are collected. In this case, as in the embodiment, the set bar 93 may be fed by the size of the interval between the pair of adjacent support claws 93b in one feed.

  In the embodiment, the suction mechanism 70 is described as including the suction contact portion 77, but this is not essential. The suction mechanism 70 may suck the surplus of the anticorrosive 18B without contacting the connection portion.

  In the embodiment, the suction mechanism 70 has been described as including the suction part moving mechanism 78, but this is not essential.

  In the embodiment, the suction contact portion 77 is described as being in contact with the connection portion from below, but this is not essential. The suction contact portion may contact the connection portion from above or from the side. In the embodiment, the suction contact portion 77 is described as being in contact with the outward surfaces of the bottom plate portions 23a, 24a, 25a, and 26a of the terminal 20, but this is not essential.

  In the embodiment, the anticorrosive 18B has been described as a member that has viscosity at a temperature in a vehicle use environment and decreases in viscosity by heating, but this is not essential. For example, the anticorrosive 18B may include a thermoplastic resin such as hot melt. Even in this case, the anticorrosive supply device 30 can be used by changing the heating temperature or the like. Further, for example, the anticorrosive 18B may include a thermosetting resin. In this case, in the anticorrosive agent supply device 30, a cooling unit provided in place of the heating units 82, 84, 86 can be used. In this case, a heating unit for curing the thermosetting resin may or may not be incorporated in the anticorrosive agent supply device. When the heating unit for curing the thermosetting resin is incorporated in the anticorrosive agent supply apparatus, the anticorrosion before the heat of the heating unit spreads before or after the supply by providing the cooling unit. It can suppress that the anticorrosive 18B becomes difficult to spread in a desired range resulting from extending to the agent 18B. For example, the anticorrosive 18B may contain a photocurable resin. In this case, it is not necessary to provide each heating part 82, 84, 86.
