Description

TECHNICAL FIELD

[0001] The present application relates to a connecting member and a connecting structure. BACKGROUND

[0002] A window glass for a vehicle provided with a vehicle-mounted device such as a defroster and a defogger, forms a power supply portion including a conductive layer on a glass plate, and the vehicle-mounted device is caused to function by supplying power to the power supply portion. In order to cause the vehicle-mounted device to function, a terminal for supplying power to the power supply portion is required, and a connecting member which can be fixed to the power supply portion is connected. In the past, lead solder has been widely used for the connection of the connecting member to the power supply portion, but due to the expansion of lead restrictions, it is required to be replaced with lead-free solder. However, the melting point of lead-free solder is 20 to 45°C higher than that of lead solder, and there is a problem that peeling easily occurs due to insufficient fixation.

[0003] As a substitute for lead-free solder, the use of a connecting member having a conductive rubber or the like is being studied (for example, refer to Patent Document 1). In the case of using a connecting member having a conductive rubber, in order to prevent the conductive rubber from becoming a high temperature state when a large current flows, it is necessary to bring the conductive rubber into close contact (intimate contact) with the power supply portion to reduce the resistance. Therefore, the connecting member is joined to the joined member including the power supply portion by a fixing member such as a heat-curing adhesive in a state in which the conductive rubber is compressed so as to be in abutment with the power supply portion.

[0004] PRIOR ART DOCUMENT

[0005] Patent Document 1: Japanese Patent No. 6070707 SUMMARY

[0006] However, as described above, in the case of fixing the connecting member and the connected member by the fixing member such as an adhesive in a state in which the conductive member such as a conductive rubber is compressed, the bubbles generated when the conductive member is compressed are likely to remain on the fixing member. If the bubbles remain on the fixing member, the fixation area decreases and the intimate contact property deteriorates. In addition, if it becomes high temperature in a state in which the bubbles remain on the fixing member, the bubbles expand, it is difficult to maintain the compressed state, and problems such as peeling and detachment occur.

[0007] Therefore, an object of the present application is to provide a connecting member and a connecting structure which can prevent bubbles from remaining on a fixing member, and can firmly fix a connecting member to a joined member in a state in which a conductive member is compressed.

[0067] Hereinafter, the present application will be described using embodiments.

[0068] [1st Embodiment]

[0069] [Connection Member]

[0070] As shown in Figure 1 , the connection member 1a of the 1st embodiment of the present application has a metal terminal 10, a conductive member 20 provided on one face (hereinafter also referred to as a 1st main face 11) of the metal terminal 10 and capable of compressive deformation, a fixing member engaged with the 1st main face 11 of the metal terminal 10, and an exhaust passage 40 provided on the metal terminal 10.

[0071] As shown in Figure 2 , the connection member 1a is a connection member connected to a connected member 100.

[0072] The connection member 1a makes the metal terminal 10 and the connected member 100 conductive by bringing the conductive member 20 into abutment with the metal terminal 10 and the connected member 100 in a state of being compressed in the thickness direction Z. By being in a state of being compressed in the thickness direction Z, the conductive member 20 is sufficiently in close contact with the metal terminal 10 and the connected member 100, and it is possible to suppress the electric resistance of the conductive member 20 to be low. By suppressing the electric resistance of the conductive member 20 to be low, it is possible to avoid the conductive member 20 from becoming in a high-temperature state even in an environment in which a large current flows.

[0073] (Metal Terminal)

[0074] The metal terminal 10 has a 1st main face 11 engaged with the fixing member 30 and a 2nd main face 12 which is the opposite face of the 1st main face 11. The metal terminal 10 is in abutment with and conductive with the conductive member 20 at the 1st main face 11. Further, the metal terminal 10 is, for example, a flat plate, and the 1st main face 11 and the 2nd main face 12 are generally faces (XY faces) perpendicular to the thickness direction Z, but do not necessarily have to be XY faces. In addition, the thickness direction Z is the thickness direction of the conductive member 20, and a current flows through the conductive member 20 in the thickness direction Z.

[0075] The metal terminal 10 may have a connector terminal 13 for cable connection. The connector terminal 13 may be formed, for example, according to JIS C2809. The connector terminal 13 is, for example, a... Figure 2 In the case of the convex terminal shown, by inserting and engaging the concave terminal on the target side, it is easy to establish a connection with the terminal on the target side. Of course, the connector terminal 13 can also be a concave terminal.

[0076] The material of the metal terminal 10 is not particularly limited; it can be any conductive metal or alloy, such as gold, silver, platinum, aluminum, copper, iron, nickel, palladium, chromium, or stainless steel. Similarly, the material of the connector terminal 13 is also not particularly limited; it can also be any conductive metal or alloy, such as gold, silver, platinum, aluminum, copper, iron, nickel, palladium, chromium, or stainless steel.

[0077] (Conductive component)

[0078] The conductive component 20 can be one, but if Figure 1 As shown, it is preferable to provide multiple conductive members 20. When multiple conductive members 20 are provided, the metal terminal 10 and the connected component 100 are electrically connected via multiple conductive members 20. Therefore, even if a large current flows between the metal terminal 10 and the connected component 100, the resistance of each conductive member 20 is suppressed to be low, thereby suppressing the temperature rise of the conductive member 20.

[0079] In addition, compared to setting a single conductive member 20 over a large area, setting multiple small conductive members 20 can reduce the load when compressing multiple conductive members 20, thus preventing the connecting part 1a from peeling off due to the repulsive force of the conductive member 20.

[0080] The diameter of the conductive member 20 is not particularly limited, for example, it is 0.4 to 5.0 mm, preferably 0.8 to 4.0 mm. Furthermore, the diameter refers to the distance between the two furthest points on the cross-section of each component (e.g., the conductive member). Additionally, the thickness of the conductive member 20 is not particularly limited, for example, it is 0.5 to 4.0 mm, preferably 0.6 to 3.0 mm.

[0081] The conductive member 20 is not particularly limited as long as it is a component capable of maintaining a compressed state and possessing conductivity; for example, a component using conductive rubber containing conductive fillers can be cited. The conductive member 20 may be entirely made of conductive rubber or partially made of conductive rubber. As a component partially made of conductive rubber, examples include a component with a conductive portion containing conductive rubber disposed at the center and an insulating portion disposed around the periphery of the conductive portion.

[0082] In addition to conductive rubber, other examples include components in which fine metal wires are arranged inside a rubber-like elastomer, components in which metal foil or metal cloth is wrapped around the outside of a rubber-like elastomer, and metal springs.

[0083] The conductive component, which is made entirely of conductive rubber, is obtained by uniformly combining conductive fillers in a rubber-like elastomer.

[0084] As conductive fillers incorporated into conductive rubber, conductive carbon black, carbon fiber, and graphite, as well as metal or alloy fillers such as silver, copper, nickel, gold, tin, zinc, platinum, palladium, iron, tungsten, molybdenum, and brazing fillers, can be used. Conductive fillers prepared by coating the surface of these particles with a conductive coating such as a metal can also be used. Alternatively, non-conductive polymer particles composed of polyethylene, polystyrene, phenolic resin, epoxy resin, acrylic resin, or benzoguanamine resin can also be used, or conductive fillers obtained by applying a conductive coating such as a metal to the surface of inorganic particles composed of glass beads, silica, graphite, or ceramics. Examples of conductive filler shapes include granular, fibrous, flake, and thread-like forms. One type of conductive filler can be used alone, or two or more types can be used in combination.

[0085] Examples of rubber-like elastomers include thermosetting rubbers and thermoplastic elastomers. Examples of thermosetting rubbers include silicone rubber, natural rubber, isoprene rubber, butadiene rubber, acrylonitrile-butadiene rubber, styrene-butadiene rubber, chloroprene rubber, nitrile rubber, butyl rubber, ethylene-propylene rubber, acrylic rubber, fluororubber, and polyurethane rubber. Silicone rubber, with its excellent processability, electrical insulation, and weather resistance, is preferred. Examples of thermoplastic elastomers include styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, ester-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, vinyl chloride-based thermoplastic elastomers, fluorinated thermoplastic elastomers, and ion-crosslinked thermoplastic elastomers. One type of rubber-like elastomer can be used alone, or two or more types can be used in combination.

[0086] like Figure 3 As shown, a conductive member 20 with conductive rubber disposed at its center has a conductive portion 21 formed by incorporating conductive filler into a rubber-like elastomer inside, and is surrounded by an insulating portion 22 made of a rubber-like elastomer around the outer periphery of the conductive portion. Furthermore, Figure 3 Although the description of the fixing member 30 is omitted here, as will be described later, it is preferable to set the fixing member 30 to surround the conductive member 20 (i.e., the insulating part 22).

[0087] The electrically conductive filler incorporated into the electrically conductive portion 21 is preferably arranged in a continuous manner in the thickness direction Z. By thus arranging the electrically conductive filler in a continuous manner in the thickness direction Z, a low resistance can be formed even under a low compression load. The same filler as the above-described electrically conductive filler can be used as the filler arranged in the thickness direction Z of the connecting member la.

[0088] Further, the electrically conductive filler incorporated into the electrically conductive portion 21 is more preferably chain-arranged in the thickness direction Z by applying a magnetic field. By thus chain-arranging the electrically conductive filler in the thickness direction Z, a lower resistance can be formed even under a low compression load. The electrically conductive filler chain-arranged in the thickness direction Z by applying a magnetic field is preferably a magnetic electrically conductive filler having magnetism and chain-arranged locally using a magnetic field or the like.

[0089] As the magnetic electrically conductive filler, for example, nickel, cobalt, iron, ferrite, and alloys thereof can be cited. The magnetic electrically conductive filler can be used singly or in combination of two or more.

[0090] As the rubber-like elastic body constituting the electrically conductive portion 21, the above-described thermosetting rubber, thermoplastic elastomer, or the like can be cited. The rubber-like elastic body constituting the electrically conductive portion 21 is preferably a material in which a liquid rubber as a liquid is cured at normal temperature (23°C) and normal pressure (1 atm) before curing, or a material capable of being heated and melted, from the viewpoint of easily arranging the electrically conductive filler in the thickness direction by applying a magnetic field or the like. The rubber-like elastic body constituting the electrically conductive portion can be used singly or in combination of two or more from among the above-described materials.

[0091] As the rubber-like elastic body constituting the insulating portion 22, the above-described thermosetting rubber, thermoplastic elastomer, or the like can be cited. The rubber-like elastic body constituting the insulating portion can likewise be used singly or in combination of two or more.

[0092] The rubber-like elastic bodies constituting the electrically conductive portion 21 and the insulating portion 22 are preferably formed integrally. Therefore, the rubber-like elastic bodies constituting the electrically conductive portion 21 and the insulating portion 22 preferably use the same kind of elastic body, and the rubber-like elastic bodies constituting the electrically conductive portion 21 and the insulating portion 22 are preferably both silicon rubber.

[0093] The electrically conductive member 20 in which the metal fine wires are arranged inside the rubber-like elastic body has a plurality of metal fine wires arranged inside the rubber-like elastic body in the thickness direction Z. The metal constituting the metal fine wires can cite gold, silver, platinum, aluminum, copper, iron, nickel, palladium, chromium, stainless steel, and the like, and alloys thereof, which have electrical conductivity. From the viewpoint of having moderate elasticity and having suitable electrical conductivity, the diameter of the metal fine wires is preferably 0.01 to 0.2 mm, and more preferably 0.02 to 0.1 mm.

[0094] The conductive member 20, which is a metal foil or metal cloth surrounding a rubber-like elastomer, is formed by wrapping a metal foil or metal cloth of conductive metals such as gold, silver, platinum, aluminum, copper, iron, nickel, palladium, chromium, and stainless steel, or their alloys, along the thickness direction Z of the conductive member 20 onto the rubber-like elastomer. From the viewpoint of having moderate elasticity and suitable conductivity, the thickness of the metal foil or metal cloth is preferably 0.001 to 0.1 mm.

[0095] The conductive component 20, which is a metal spring, is made of conductive metals such as gold, silver, platinum, aluminum, copper, iron, nickel, palladium, chromium, and stainless steel, as well as their alloys. Examples of metal springs include helical springs and leaf springs.

[0096] (Fixed components and connecting components)

[0097] like Figure 2 As shown, the fixing member 30 is a member that engages with both the metal terminal 10 and the connected component 100 to fix the metal terminal 10 and the connected component 100. Because the connecting member 1a has the fixing member 30, the metal terminal 10 and the connected component 100 can be electrically connected via the conductive member 20, and the metal terminal 10 is reliably and easily fixed to the connected component 100. Therefore, even if the conductive member 20 is fixed in the compressed state as described above, the connecting member 1a is not easily detached from the connected component 100.

[0098] The fixing member 30 of this embodiment has a first fixing surface 31 and a second fixing surface 32 opposite to the first fixing surface 31. Both the first fixing surface 31 and the second fixing surface 32 are surfaces that can be engaged. The first fixing surface 31 and the second fixing surface 32 are generally XY surfaces perpendicular to the Z direction, but they may not be XY surfaces. The first fixing surface 31 is engaged with the metal terminal 10, and the second fixing surface 32 is engaged with the connected component 100.

[0099] From the viewpoint of stabilizing and fixing the conductive member 20 under compressed conditions, it is preferable to form the fixing member 30 in a manner that surrounds the conductive member 20. When the fixing member 30 surrounds the conductive member 20, it can be joined to the entire surface of the first main surface 11 of the metal terminal 10, or it can be joined to a portion thereof. Of course, if the fixing member 30 is formed around the conductive member 20, it is not necessary to surround it.

[0100] like Figure 1As shown, the thickness of the fixing member 30 is preferably smaller than the thickness of the conductive member 20. Further, the thickness of the fixing member 30 is the distance in the thickness direction Z of the first fixing surface 31 and the second fixing surface 32. By making the thickness of the fixing member 30 smaller than the thickness of the conductive member 20, the connecting member la can be fixed to the connected member 100 in a state where the conductive member 20 is compressed. The thickness of the fixing member 30 is not particularly limited, and is, for example, 0.1 to 3.0 mm, and is preferably 0.3 to 2.7 mm.

[0101] As shown, the connecting member la in the present embodiment can further include a connecting member 50 that links the conductive member 20 and the fixing member 30. Figure 1

[0102] The connecting member 50 is a planar sheet member, and is, for example, composed of a resin sheet. The resin sheet is not particularly limited as long as it has a certain strength that enables the conductive member 20 and the fixing member 30 to be linked. In addition, the resin sheet can use a resin sheet having flexibility. As the resin sheet, for example, a polyethylene terephthalate (PET) sheet, a polyethylene naphthalate sheet, a polycarbonate sheet, a polyether ether ketone sheet, a polyimide sheet, a polyamide sheet, a polyethylene sheet, a polypropylene sheet, a polyurethane sheet, or the like can be used. Among them, from the viewpoint of durability, heat resistance, and the like, a PET sheet and a polyimide sheet are preferable, and from the viewpoint of improving the positional accuracy of the conductive member 20, a polyimide sheet is preferable.

[0103] The thickness of the connecting member 50 (resin sheet) is not particularly limited, and is, for example, 30 to 500 μm, and is preferably 50 to 350 μm.

[0104] In the case where a plurality of conductive members 20 are provided, the connecting member 50 can link the plurality of conductive members 20 together. For example, through holes can be provided in the connecting member 50, and each conductive member 20 can be inserted into the inside of each through hole and fixed to the connecting member 50.

[0105] The fixing member 30 uses an adhesive and a bonding agent, or the like. The adhesive is a pressure-sensitive bonding agent that is bonded only by applying pressure at normal temperature. As the adhesive, a publicly known adhesive can be used, and for example, an acrylic adhesive, a polyurethane adhesive, a silicone adhesive, a rubber adhesive, or the like can be cited. As the bonding agent, there is no particular limitation as long as it has a bonding property that enables the metal terminal 10 and the connected member 100 to be bonded, and for example, a hot melt bonding agent, a thermosetting bonding agent, an ultraviolet curing bonding agent, a moisture curing bonding agent, or the like can be cited.

[0106] ​The first fixing surface 31 and the second fixing surface 32 of the fixing member 30 can be composed of any one of an adhesive and a bonding agent, but are preferably composed of the bonding agent. By the fixing surfaces being composed of the bonding agent, the connection member 1a provided with the fixing member 30 can be brought into contact with the connected member 100, and the connection member 1a and the connected member 100 can be fixed by pressing alone.

[0107] As shown in FIG. 1, the fixing member 30 can be provided with a first fixing portion 33 and a second fixing portion 34 provided on both surfaces of the sheet-shaped connection member 50, respectively. The first fixing portion 33 and the second fixing portion 34 can be separate bonding agent layers, or can be double-sided adhesive tapes. The double-sided adhesive tape is provided with a base material and bonding agent layers provided on both surfaces of the base material. The bonding agent layer is a layer composed of the above-described bonding agent. Figure 1

[0108] In the case of using the bonding agent layer alone, the bonding agent layer can be laminated onto the surface of the sheet-shaped connection member 50. In the case of laminating the bonding agent layer, the bonding agent can be applied to the connection member 50 or the like by a publicly known method.

[0109] In the case of the double-sided adhesive tape, the bonding agent layer on one side is joined to the connection member 50, and the surface of the bonding agent layer on the other side can be used as the first fixing surface or the second fixing surface.

[0110] As the base material of the double-sided adhesive tape, a publicly known base material used as the base material of the double-sided adhesive tape can be used, and examples thereof include a resin film, a nonwoven fabric, and a foamed sheet.

[0111] (Vent passage)

[0112] In the present embodiment, the vent passage 40 is a first vent groove 40a provided on the metal terminal 10, more specifically, on the first main surface 11 of the metal terminal 10. The first vent groove 40a can be provided on at least the surface to which the fixing member 30 is joined.

[0113] The first vent passage 40a is connected to the first fixing surface 31, and can discharge air bubbles generated on the first fixing surface 31, more specifically, at the interface between the first fixing surface 31 and the first main surface 11. That is, when the fixing member 30 is joined to the metal terminal 10, the vent passage 40a can discharge air bubbles generated on the first fixing surface 31, that is, at the above-described interface.

[0114] As shown in FIG. 1, the fixing member 30 can be provided with a first fixing portion 33 and a second fixing portion 34 provided on both surfaces of the sheet-shaped connection member 50, respectively. The first fixing portion 33 and the second fixing portion 34 can be separate bonding agent layers, or can be double-sided adhesive tapes. The double-sided adhesive tape is provided with a base material and bonding agent layers provided on both surfaces of the base material. The bonding agent layer is a layer composed of the above-described bonding agent. Figure 1 ​As shown, the first venting channel 40a can have a structure that extends to the end of the metal terminal 10. When connected to the end, the venting passage 40 is connected to the outside and is not covered by the first fixing surface 31, so air bubbles at the interface can be effectively discharged to the outside. However, the first venting channel 40a does not necessarily have to be connected to the end of the metal terminal 10; it is sufficient to connect it to the ends 30a and 30b of the fixing member 30. When connected to the ends 30a and 30b of the fixing member 30, the venting passage 40 is connected to the outside at the ends 30a and 30b of the fixing member 30, allowing air bubbles generated at the first fixing surface 31 to be discharged to the outside from the ends 30a and 30b.

[0115] The first venting groove 40a can be formed by general metal processing such as milling and laser processing.

[0116] The first venting groove 40a can be of various shapes as long as it is a structure capable of venting bubbles to the outside; for example, it can be straight or curved. In addition, the linear grooves can intersect each other or not.

[0117] like Figure 4 As shown, the first venting groove 40a is preferably disposed around the conductive member 20. When the metal terminal 10 and the fixing member 30 are joined while the conductive member 20 is compressed, air bubbles are easily generated around the conductive member 20. Therefore, by disposing the first venting groove 40a around the conductive member 20, air bubbles generated at the interface between the metal terminal 10 and the fixing member 30 can be effectively discharged. When the first venting groove 40a (venting passage 40) is disposed around the conductive member 20, the shortest distance D1 between the first venting groove 40a (venting passage 40) and the conductive member 20 is preferably 15 mm or less, more preferably 10 mm or less, and most preferably 0 mm. That is, it is most preferably disposed such that the first venting groove 40a is in contact with the conductive member 20.

[0118] In addition, the width of the first exhaust groove 40a is, for example, 0.1 to 5.0 mm, preferably 0.2 to 3.0 mm, and the depth is, for example, 0.01 to 2.0 mm, preferably 0.02 to 1.0 mm.

[0119] Furthermore, when multiple conductive members 20 are provided in the first exhaust groove 40a (exhaust passage 40), it is preferable to arrange them between the conductive members 20, 20. By arranging the first exhaust groove 40a between the multiple conductive members 20, air bubbles that are easily generated between the conductive members 20 can be effectively discharged.

[0120] Regarding the first vent groove 40a provided on the first main surface 11 of the metal terminal 10, refer to Figure 4 To explain in more detail its positional relationship with the conductive component 20.

[0121] Figure 4 (a) The first air vent 40a is arranged in a lattice pattern on the first main surface 11. Figure 4 (b) The first air vent 40a is arranged in an X pattern on the first main surface 11. Figure 4 (c) The first air vent 40a is arranged in a zigzag pattern on the first main surface 11. Figure 4 (d) The first air vent 40a is arranged in two parallel lines.

[0122] Figure 4 The first air vent 40a is arranged to contact the position where the conductive member 20 is connected to the first main surface 11 in (a) to (c). In addition, Figure 4 The first air vent 40a is arranged in a position close to the conductive member 20 in (d). That is, in (d), Figure 4 In (a) to (d), the first air vent 40a is arranged around the conductive member 20, so that the bubbles generated around the conductive member 20 can be effectively discharged by the first air vent 40a.

[0123] Further, in (a) to (c), Figure 4 In (a) to (c), the first air vent 40a is arranged to contact the conductive member 20, so that the shortest distance between the first air vent 40a and the conductive member 20 is 0 mm.

[0124] Figure 4 The first air vent 40a is arranged in a position away from the position where the conductive member 20 is connected to the first main surface 11 in (d). In Figure 4 In (d), the shortest distance Dl between the first air vent 40a and the conductive member 20 is indicated. As described above, the shortest distance Dl is 15 mm or less. As Figure 4 As shown in (d), even if the first air vent 40a does not contact the conductive member 20, when the first fixed surface 31 is joined to the metal terminal 10, the bubbles generated around the conductive member 20 can be effectively discharged.

[0125] Further, as shown in (a) to (d), Figure 4 As shown in (a) to (d), each conductive member 20 can be sandwiched or surrounded by two or more first air vents 40a. According to this manner, the bubbles generated around the conductive member 20 can be more effectively discharged.

[0126] Furthermore, the first vent groove 40a (vent passage 40) can serve as a positioning element when the conductive member 20 is fixed to the metal terminal 10 by the fixing member 30. For example, when the conductive member 20 is configured as described above to be clamped or surrounded by the first vent groove 40a, the first vent groove 40a suitably functions as a positioning element. In this case, when the first vent groove 40a is configured to contact the conductive member 20, the first vent groove 40a more suitably functions as a positioning element.

[0127] (Connection structure)

[0128] like Figure 2 As shown, the connection structure 2a of the first embodiment of the present invention includes the connection member 1a and the connected member 100 described above. That is, the connection structure 2a includes the connected member 100, the metal terminal 10, the conductive member 20, and the fixing member 30.

[0129] The conductive member 20 and the fixing member 30 are disposed between the metal terminal 10 and the connected component 100. In the fixing member 30, the first fixing surface 31 and the second fixing surface 32 respectively engage with the metal terminal 10 and the connected component 100. The fixing member 30 fixes the metal terminal 10 and the connected component 100 in a state where the conductive member 20 is in contact with and compressed against both the metal terminal 10 and the connected component 100. Thus, a state in which the metal terminal 10 is electrically connected to the connected component 100 through the conductive member 20 is maintained.

[0130] The connected component 100 includes, for example, a connected component 110 such as a glass plate and a power supply section 111 formed on the surface of the connected component 110. The power supply section 111 is a portion formed in a linear shape on the surface of the connected component 110 for supplying power to linear conductors such as defrosters, demisters, and antenna elements. The conductive member 20 abuts against the power supply section 111, thereby making the metal terminal 10 and the connected component 110 conductive.

[0131] In the fabrication of the connection structure 2a according to the first embodiment of the present invention, firstly, a conductive member 20 and a fixing member 30 connected by a connecting member 50 are prepared. Next, the first fixing surface 31 of the fixing member 30 is joined to the first main surface 11 of the metal terminal 10, thereby obtaining the connection member 1a. The obtained connection member 1a can be fixed to the connected member 100 via the second fixing surface 32 of the fixing member 30 to obtain the connection structure 2a.

[0132] However, the connection structure 2a can also be obtained by first fixing the conductive member 20 and the fixing member 30 connected by the connecting member 50 to the connected member 100 via the second fixing surface 32, and then installing the metal terminal 10 on the first fixing surface 31.

[0133] According to the first embodiment of the present invention, the connecting member 1a and the connecting structure 2a, by providing a first venting groove 40a on the first main surface 11 of the metal terminal 10 as a venting passage 40, can effectively discharge air bubbles generated on the first fixing surface 31 of the fixing member 30. In the connecting member 1a and the connecting structure 2a, by effectively discharging air bubbles, air bubbles will not remain on the fixing member 30, and the metal terminal 10 can be reliably and easily fixed to the connected member 100 while the conductive member 20 is compressed.

[0134] [Second Implementation]

[0135] like Figure 5 As shown, the connection member 1b and connection structure 2b of the second embodiment are different from the connection member 1a and connection structure 2b of the first embodiment in that the exhaust passage 40 is provided on the first fixing surface 31 of the fixing member 30 that engages with the metal terminal 10.

[0136] The differences between the second embodiment and the first embodiment will be described below. Furthermore, in the following descriptions of different embodiments, components having the same structure will be labeled with the same reference numerals.

[0137] Figure 5 The exhaust passage 40 is provided on the first fixing surface 31, and the second exhaust groove 40b is provided to discharge bubbles generated on the first fixing surface 31. The second exhaust groove 40b is preferably a structure that connects to the ends 30a and 30b of the fixing member 30. By forming the structure of the second exhaust groove 40b connecting to the ends 30a and 30b, bubbles generated on the first fixing surface 31 (more specifically, the interface between the first fixing surface 31 and the first main surface 11) can be discharged to the outside gas from the ends 30a and 30b. The second exhaust groove 40b, which is the exhaust passage 40, can be formed by general resin processing such as laser processing. In addition, by peeling the fixing member 30 provided on the grooved and uneven release sheet from the release sheet, the fixing member 30 having the second exhaust groove 40b can be formed.

[0138] Reference Figure 6 The second exhaust groove 40b, located on the first fixing surface 31 of the fixing member 30, will be described in more detail. The structure of the second exhaust groove 40b is the same as that of the first exhaust groove 40a, and it can form a shape similar to... Figure 4The positional relationship of the first exhaust groove 40a provided on the first main surface 11 of the metal terminal 10 and the conductive member 20 is the same as the positional relationship described above. That is, the second exhaust groove 40b is preferably provided around the conductive member 20, and the shortest distance D2 from the conductive member 20 is preferably 15 mm or less, more preferably 10 mm or less, and most preferably 0 mm, as described above. In addition, in the case where a plurality of conductive members 20 are provided in the second exhaust groove 40a (exhaust passage 40), the second exhaust groove 40b is preferably provided so as to be positioned between the conductive members 20, 20.

[0139] In addition, the width of the second exhaust groove 40b is, for example, 0.05 to 5.0 mm, and is preferably 0.2 to 3.0 mm, and the depth is, for example, 0.01 to 2.0 mm, and is preferably 0.02 to 1.0 mm.

[0140] In addition, more specifically, Figure 6 (a) The second exhaust groove 40b is provided on the first fixing surface 31 in a lattice shape. Figure 6 (b) The second exhaust groove 40b is provided on the first fixing surface 31 in an X shape. Figure 6 (c) and Figure 6 (d) Two second exhaust grooves 40b are provided, and are provided in parallel to each other. Figure 6 (e) A plurality of second exhaust grooves 40b are provided on the first fixing surface 31, and are provided so as to cross each other, thereby forming a plurality of crossing grooves. In Figure 6 (e) In the second exhaust groove 40b, the pitch between adjacent second exhaust grooves 40b is, for example, 0.2 to 1.5 mm, and is preferably 0.5 to 1.0 mm.

[0141] According to the connection member 1b and the connection structure 2b of the second embodiment of the present application, by providing the second exhaust groove 40b as the exhaust passage 40 on the first fixing surface 31 of the fixing member 30, the bubbles generated on the first fixing surface 31 of the fixing member 30 can be discharged well. By discharging the bubbles well by the connection member 1b and the connection structure 2b, the bubbles do not remain in the fixing member 30, and the metal terminal 10 can be surely and easily prepositioned to the connected member 100 in a state where the conductive member 20 is compressed.

[0142] [Third Embodiment]

[0143] As Figure 7 indicated, the connection member 1c and the connection structure 2c of the third embodiment differ from the connection member 1a and the connection structure 2a of the first embodiment in that the exhaust passage 40 is provided on the second fixing surface 32 of the fixing member 30.

[0144] The differences between the third embodiment and the first embodiment will be described below. Furthermore, in the following descriptions of different embodiments, components having the same structure will be labeled with the same reference numerals.

[0145] Figure 7 The exhaust passage 40 is provided on the second fixing surface 32 of the fixing member 30, which engages with the connected component 100, and a third exhaust groove 40c is provided to discharge bubbles generated on the second fixing surface 32. The third exhaust groove 40c is preferably a structure that extends to the ends 30a and 30b of the fixing member 30. By forming the third exhaust groove 40c that extends to the ends 30a and 30b, bubbles generated on the second fixing surface 32 can be discharged from the ends 30a and 30b to the outside gas.

[0146] The third exhaust groove 40c, which serves as the exhaust passage 40, can be formed by conventional resin processing such as laser processing. Alternatively, by peeling the fixing member 30, which is provided on a release sheet with a grooved and uneven shape, from the release sheet, a fixing member 30 having the third exhaust groove 40c can be formed.

[0147] Reference Figure 8 The third vent groove 40c provided on the second fixing surface 32 of the fixing member 30 will be described in more detail.

[0148] The structure of the third exhaust groove 40c is the same as that of the first exhaust groove 40a, and it can form with Figure 4 The first venting groove 40a, provided on the first main surface 11 of the metal terminal 10, and the conductive member 20 are positioned in the same manner. That is, the third venting groove 40c is preferably disposed around the conductive member 20, and its shortest distance D3 from the conductive member 20, as described above, is preferably 15 mm or less, more preferably 10 mm or less, and most preferably 0 mm. Furthermore, when multiple conductive members 20 are provided, the third venting groove 40c is preferably disposed between the conductive members 20, 20. Additionally, the width of the third venting groove 40c is, for example, 0.05 to 5.0 mm, preferably 0.2 to 3.0 mm, and the depth is, for example, 0.01 to 2.0 mm, preferably 0.02 to 1.0 mm.

[0149] More specifically, such as Figure 8 As shown in (a) to (d), the third exhaust groove 40c can be arranged in a grid pattern, an X-shape, or two parallel grooves on the second fixed surface 32. Additionally, as... Figure 8 As shown in (e), multiple third exhaust channels 40c are provided on the second fixed surface 32 and are arranged intersectingly to form multiple intersecting channels. Figure 8(e) In the illustrated third row of air grooves 40c, the pitch between adjacent third row of air grooves 40c is, for example, 0.2 to 1.5 mm, and preferably 0.5 to 1.0 mm.

[0150] According to the connection member 1c and the connection structure 2c of the third embodiment of the present application, by providing the third row of air grooves 40c as the air escape passage 40 on the second fixing surface 32 of the fixing member 30, the air bubbles generated at the second fixing surface 32 (i.e., the interface between the second fixing surface 32 and the connected member 100) can be favorably escaped. By the connection member 1c and the connection structure 2c favorably escaping the air bubbles, the air bubbles do not remain in the fixing member 30, and the metal terminal 10 can be favorably and easily fixed to the connected member 100 in a state where the conductive member 20 is compressed.

[0151] [Fourth Embodiment]

[0152] As illustrated in Figure 9 , in the connection member 1d of the fourth embodiment, the air escape passage 40 includes a first air escape hole 40d that penetrates from the first main surface 11 to the second main surface 12 of the metal terminal 10. In this respect, the connection member 1d of the fourth embodiment is different from the connection member 1a of the first embodiment. Hereinafter, the differences between the fourth embodiment and the first embodiment will be described. Also, hereinafter, in the description of the different embodiments, the same reference numerals are attached to the members having the same structure.

[0153] Figure 9 The air escape passage 40 in the fourth embodiment is the first air escape hole 40d that penetrates from the first main surface 11 to the second main surface 12 of the metal terminal 10. By forming a structure that penetrates from the first main surface 11 to the second main surface 12 of the metal terminal 10 through the first air escape hole 40d, the air bubbles generated at the first fixing surface 31 can be escaped to the outside air from the second main surface 12 side.

[0154] The first air escape hole 40d as the air escape passage 40 can be formed by general metal processing such as milling, drilling, and laser processing.

[0155] As illustrated in Figure 9 and Figure 10 , the first air escape hole 40d is preferably provided around the position on the first main surface 11 where the conductive member 20 is connected. By providing the first air escape hole 40d around the conductive member 20, the air bubbles generated at the first fixing surface 31 around the conductive member 20 can be escaped through the first air escape hole 40d. As described above, the shortest distance D4 between the first air escape hole 40d and the conductive member 20 is preferably 15 mm or less, more preferably 10 mm or less, and most preferably 0 mm. That is, as illustrated in Figure 10 (a), most preferably, the first air escape hole 40a is in contact with the conductive member 20 on the first main surface 11.

[0156] Further, in the case where a plurality of conductive members 20 are provided, as shown in Figure 10 (a), (b), the first exhaust hole 40d (exhaust passage 40) is preferably provided so as to be positioned between the conductive members 20, 20.

[0157] The first exhaust hole 40d is not particularly limited, and can have a larger diameter than the conductive members 20, can have the same diameter, or can have a smaller diameter, but from the viewpoint of the strength of the metal terminal 10 and the like, it is preferable to have a smaller diameter than the conductive members 20. The diameter of the first exhaust hole 40d is not particularly limited, and is, for example, 0.01 to 5.0 mm, and is preferably 0.02 to 4.0 mm.

[0158] As shown in Figure 11 , the first exhaust hole 40d can be formed so as to communicate with the first exhaust groove 40a shown in the first embodiment. By forming the first exhaust hole 40d so as to communicate with the first exhaust groove 40a, the bubbles generated at the first fixing surface 31 of the fixing member 30 can be more favorably exhausted. Further, in the case where the first exhaust hole 40d and the first exhaust groove 40a are provided, either one of the shortest distance Dl of the first exhaust groove 40a from the conductive member 20 and the shortest distance D4 of the first exhaust hole 40d from the conductive member 20 can be within the above range (i.e., the distance of the exhaust passage 40 from the conductive member 20 can be 15 mm or less), but it is preferable that both be within the above range. As described below, the same applies to other modes in which two or more exhaust passages are provided.

[0159] In addition, as shown in Figure 12 , the first exhaust hole 40d can also be formed so as to communicate with the second exhaust groove 40b shown in the second embodiment. By forming the first exhaust hole 40d so as to communicate with the second exhaust groove 40b, the bubbles generated at the first fixing surface 31 of the fixing member 30 can be more favorably exhausted.

[0160] In order to communicate with the first exhaust groove 40a or the second exhaust groove 40b, the first exhaust hole 40d can be formed so as to overlap the position at which the first exhaust groove 40a or the second exhaust groove 40b is provided.

[0161] According to the connection member 1d and the connection structure 2d of the fourth embodiment of the present application, by providing the first exhaust hole 40d that penetrates from the first main surface 11 to the second main surface 12 of the metal terminal 10, the bubbles generated at the first fixing surface 31 of the fixing member 30 can be favorably exhausted. By the connection member 1d and the connection structure 2d favorably exhausting the bubbles, the bubbles do not remain in the fixing member 30, and the metal terminal 10 can be fixed to the connected member 100 in a state in which the conductive members 20 are compressed with certainty and easily.

[0162] [5th Embodiment]

[0163] As shown in FIG. 5, the exhaust passage 40 of the connecting member 1e of the fifth embodiment includes a second exhaust hole 40e that penetrates from the first fixing surface 31 to the second fixing surface 32 of the fixing member 30, unlike the connecting member 1a of the first embodiment. Hereinafter, the differences between the fifth embodiment and the first embodiment will be described. In addition, hereinafter, the same reference numerals are attached to members having the same structure in the description of different embodiments. Figure 13 The second exhaust hole 40e penetrates the connecting member 50 in addition to the fixing member 30. That is, the second exhaust hole 40e is a through hole that penetrates the first fixing portion 33, the connecting member 50, and the second fixing portion 34. As shown in FIG. 5, the second exhaust hole 40e can be formed to communicate with the first exhaust groove 40a shown in the first embodiment. By forming the structure in which the second exhaust hole 40e communicates with the first exhaust groove 40a, the air bubbles generated at the second fixing surface 32 (the interface of the second fixing surface 32 and the joined member 100) can also be discharged to the outside via the second exhaust hole 40e and the first exhaust groove 40a. In addition, the air bubbles generated at the first fixing surface 31 (the interface of the first fixing surface 31 and the first main surface 11X) can also be favorably discharged via the first exhaust groove 40a.

[0164] Figure 13 As shown in FIG. 6, the second exhaust hole 40e can be formed to communicate with the second exhaust groove 40b shown in the second embodiment. By forming the structure in which the second exhaust hole 40e communicates with the second exhaust groove 40b, the air bubbles generated at the second fixing surface 32 can be discharged to the outside via the second exhaust hole 40e and the second exhaust groove 40a. In addition, the air bubbles generated at the first fixing surface 31 can be discharged to the outside via the second exhaust groove 40a.

[0165] As shown in FIG. 7, the second exhaust hole 40e can be formed to communicate with the third exhaust groove 40c shown in the third embodiment. By forming the structure in which the second exhaust hole 40e communicates with the third exhaust groove 40e, the air bubbles generated at the second fixing surface 32 (the interface of the second fixing surface 32 and the joined member 100) can be discharged to the outside via the third exhaust groove 40c. In addition, the air bubbles generated at the first fixing surface 31 (the interface of the first fixing surface 31 and the first main surface 11X) of the fixing member 30 can be favorably discharged via the second exhaust hole 40e or the like. Figure 14 As shown in FIG. 8, the second exhaust hole 40e can be formed to communicate with the fourth exhaust groove 40d shown in the fourth embodiment. By forming the structure in which the second exhaust hole 40e communicates with the fourth exhaust groove 40d, the air bubbles generated at the second fixing surface 32 can be discharged to the outside via the second exhaust hole 40e and the fourth exhaust groove 40d. In addition, the air bubbles generated at the first fixing surface 31 can be discharged to the outside via the fourth exhaust groove 40d.

[0166] Figure 15 In addition, as shown in FIG. 9, the second exhaust hole 40e can be formed to communicate with the fifth exhaust groove 40e shown in the fifth embodiment. By forming the structure in which the second exhaust hole 40e communicates with the fifth exhaust groove 40e, the air bubbles generated at the second fixing surface 32 (the interface of the second fixing surface 32 and the joined member 100) can be discharged to the outside via the fifth exhaust groove 40e. In addition, the air bubbles generated at the first fixing surface 31 (the interface of the first fixing surface 31 and the first main surface 11X) of the fixing member 30 can be favorably discharged via the second exhaust hole 40e or the like.

[0167] In addition, as shown in FIG. 10, the second exhaust hole 40e can be formed to communicate with the sixth exhaust groove 40f shown in the sixth embodiment. By forming the structure in which the second exhaust hole 40e communicates with the sixth exhaust groove 40f, the air bubbles generated at the second fixing surface 32 can be discharged to the outside via the second exhaust hole 40e and the sixth exhaust groove 40f. In addition, the air bubbles generated at the first fixing surface 31 can be discharged to the outside via the sixth exhaust groove 40f. Figure 16 ​​As shown, the second vent hole 40e can form a structure that communicates with the first vent hole 40d shown in the fourth embodiment. By forming the structure in which the second vent hole 40e communicates with the first vent hole 40d, the air bubbles generated at the first fixing surface 31 of the fixing member 30 can be discharged to the outside via the first vent hole 40d or the like. In addition, the air bubbles generated at the second fixing surface 32 can be favorably discharged to the outside via the first vent hole 40d and the second vent hole 40e or the like.

[0168] Referring to Figure 17 The second vent hole 40e provided from the first fixing surface 31 to the second fixing surface 32 of the fixing member 30 will be described in more detail.

[0169] As Figure 17 shown, the second vent hole 40e is preferably provided around the position on the first main surface 11 at which the conductive member 20 is connected. The second vent hole 40e is provided around the conductive member 20, so that the air bubbles generated at the first fixing surface 31 and the second fixing surface 32 around the conductive member 20 can be discharged through the second vent hole 40e. As described above, the shortest distance D5 from the second vent hole 40e to the conductive member 20 is preferably 15 mm or less, and more preferably 10 mm or less. In addition, from the viewpoint of appropriately fixing the conductive member 20 by the fixing member 30, it is preferable that the second vent hole 40e does not contact the conductive member 20. Therefore, the shortest distance D5 is preferably 0.1 mm or more, and more preferably 0.5 mm or more.

[0170] Further, in the case where a plurality of conductive members 20 are provided, the second vent hole 40e is preferably provided so as to be positioned between the conductive members 20, 20. The second vent hole 40e is not particularly limited, and can have a larger diameter than the conductive member 20, can have the same diameter, or can have a smaller diameter. However, from the viewpoint of not reducing the joining force of the fixing member 30, the second vent hole 40e preferably has a smaller diameter than the conductive member 20. The diameter of the second vent hole 40e is not particularly limited, and is, for example, 0.01 to 5 mm, and is preferably 0.02 to 4 mm.

[0171] More specifically, the second vent hole 40e can be provided as shown in Figure 17 (a), (d) so as to have a larger diameter than the diameter of the conductive member 20 between the conductive members 20, can be provided as shown in Figure 17 (b) so as to be a plurality of holes between the conductive members 20. In addition, the second vent hole 40e can be provided as shown in Figure 17 (c) so as to be a plurality of holes so as to surround the conductive member 20.

[0172] To communicate with the first air vent groove 40a, the second air vent groove 40b, the third air vent groove 40c, or the first air vent hole 40d, the second air vent hole 40e can be formed so as to overlap the position where they are provided. For example, by combining Figure 17 the second air vent hole 40e shown in (d) and Figure 10 the first air vent hole 40d shown in (c), the first air vent hole 40e and the second air vent hole 40d can be communicated.

[0173] According to the connecting member 1e and the connecting structure 2e of the fifth embodiment of the present application, by providing the second air vent hole 40e that penetrates from the first fixing surface 31 to the second fixing surface 32 of the fixing member 30, the air bubbles generated in at least one of the first fixing surface 31 and the second fixing surface 32 of the fixing member 30 can be well discharged. By well discharging the air bubbles by the connecting member 1e and the connecting structure 2e, the air bubbles do not remain in the fixing member 30, and the metal terminal 10 can be fixed to the connected member 100 in a state where the conductive member 20 is compressed, with certainty and easily.

[0174] Further, in the above description of the fifth embodiment, the structure in which the air vent passage 40 has any of the first air vent groove 40a, the second air vent groove 40b, the third air vent groove 40c, and the first air vent hole 40d in addition to the second air vent hole 40e is described. However, the first air vent groove 40a, the second air vent groove 40b, the third air vent groove 40c, and the first air vent hole 40d can not be provided, and the air vent passage 40 can be composed of the second air vent hole 40e alone.

[0175] Even in the case where the second air vent hole 40e is alone, for example, in the case where the fixing member 30 and the conductive member 20 are attached to the metal terminal 10 before being fixed to the connected terminal 100, the air bubbles generated in the first fixing surface 31 (i.e., the interface of the first fixing surface 31 and the metal terminal 10) can be discharged to the outside via the second air vent hole 40e.

[0176] Further, after the fixing member 30 and the conductive member 20 are attached to the metal terminal 10, when the fixing member 30 and the conductive member 20 are attached to the connected terminal 100, the second air vent hole 40e is not communicated with the outside. However, as described in the sixth embodiment described later, by the difference in volume of the gas accompanying the change in temperature, the gas of the first fixing surface 31 and the second fixing surface 32 can escape to the inside of the second air vent hole 40e.

[0177] Furthermore, the second vent 40e is not limited to a hole with a hollow interior; it can also be a cut from the first fixing surface 31 to the second fixing surface 32, and the second vent 40e also includes such a cut. Similarly, the first vent 40d can also be a cut. The cut forms a generally uniform amplitude, and can also be, for example, an elliptical shape with varying amplitude. The length of the cut can be longer than the diameter of the aforementioned first vent 40d and second vent 40e. For example, it can be about 4mm to 10mm long, or it can reach the outer edge of the metal terminal 10 or the fixing member 30.

[0178] [Sixth Implementation]

[0179] like Figures 18-20 As shown, the exhaust passage 40 of the connecting member 1f in the sixth embodiment has a bottom hole 40f, which differs from the connecting member 1a in the first embodiment. The differences between the sixth embodiment and the first embodiment will be described below. Furthermore, in the following descriptions of different embodiments, components with the same structure will be labeled with the same reference numerals.

[0180] Figure 18 The exhaust passage 40 is a bottom hole 40f provided on the first main surface 11 of the metal terminal 10. Figure 19 The exhaust passage 40 is a bottom hole 40f provided on the first fixed surface 31 of the fixed member 30. Figure 18 and Figure 19 The bottom hole 40f in the middle can contain the air bubbles generated on the first fixed surface 31 (i.e., the interface between the first fixed surface 31 and the first main surface 11).

[0181] Figure 20 The exhaust passage 40 is a bottom hole 40f located on the second fixing surface 32 of the fixing member 30. Figure 20 The bottom hole 40f can contain air bubbles generated on the second fixing surface 32 (i.e., the interface between the second fixing surface 32 and the connected component 100).

[0182] Furthermore, the bottom hole 40f provided on the fixing member 30 may penetrate the connecting member 50, or it may not penetrate it, or it may penetrate to the middle of the connecting member 50. In addition, the surface of the connecting member 50 may form the bottom surface of the bottom hole 40f.

[0183] Gas is pre-existing inside the bottom hole 40f, so the volume difference of the gas is utilized to contain the bubble inside. Specifically, when the fixing member 30 is joined to the metal terminal 10 or the connected part 100, the gas inside the bottom hole 40f is expanded by heating, and then the gas inside the bottom hole 40f is contracted by cooling to room temperature, leaving room inside the bottom hole 40f so that the bubble can be contained inside.

[0184] The bottom hole 40f, which serves as the exhaust passage 40, can be formed by general metal processing such as milling and laser processing, as well as general resin processing such as laser processing. Alternatively, the fixing member 30 with the bottom hole 40f can be formed by peeling the fixing member 30, which is provided on a release tab with a hole and an uneven shape, from the release tab.

[0185] According to the sixth embodiment of the present invention, the connecting member 1f and the connecting structure 2f, by providing a bottom hole 40f on at least one of the metal terminal 10 and the fixing member 30, can effectively accommodate air bubbles generated on at least one of the first fixing surface 31 and the second fixing surface 32 of the fixing member 30. Because the connecting member 1f and the connecting structure 2f effectively accommodate air bubbles, preventing them from remaining on the fixing member 30, the metal terminal 10 can be reliably and easily fixed to the connected member 100 while the conductive member 20 is compressed.

[0186] [Seventh Implementation]

[0187] like Figure 21 As shown, in the connecting member 1g of the seventh embodiment, the second main surface 12 of the metal terminal 10 has a protrusion 60, which differs from the connecting member 1a of the first embodiment. Hereinafter, the differences between the seventh embodiment and the first embodiment will be described. Furthermore, in the following descriptions of different embodiments, components having the same structure will be labeled with the same reference numerals.

[0188] like Figure 21 As shown, in this embodiment, a protrusion 60 may be provided in the connecting member 1g, and an exhaust groove 40g (first exhaust groove) may be provided inside the protrusion 60. The exhaust groove 40g may constitute at least a portion of the first exhaust groove provided on the first main surface 11 of the metal terminal 10.

[0189] If a protrusion 60 is provided on the metal terminal 10, when the conductive member 20 is fixed to the metal terminal 10 by the fixing member 30 while supporting the protrusion 60, pressure is applied to the protrusion 60 and its vicinity. Therefore, air bubbles generated when the fixing member 30 is joined to the metal terminal 10 can be effectively discharged to the outside through an exhaust passage such as the exhaust groove 40g.

[0190] Further, in the case where the protrusion 60 is provided, the exhaust groove provided in the metal terminal 10 can be only the exhaust groove 40g provided inside the protrusion 60 as shown in Figure 21 , or can be provided also outside the protrusion 60 (first exhaust groove) as shown in Figure 22 . The exhaust groove (exhaust groove 40a) outside the protrusion 60 can be configured as shown in Figure 4 . Further, Figure 23 , for example, the exhaust groove 40a is configured in a lattice shape as shown in Figure 4 (a). By providing the exhaust groove at an arbitrary position inside the protrusion 60 and outside the protrusion 60, the bubbles formed on the first fixing surface 31 of the fixing member 30 can be more effectively exhausted to the outside.

[0191] The protrusion 60 is preferably provided at a position corresponding to a position where bubbles are easily generated in the fixing member 30. That is, as a position where the protrusion 60 is provided, it is preferable to be provided near a position where the conductive member 20 is disposed, that is, a position where bubbles are easily generated. Specifically, the shortest distance D6 (see Figure 21 ) between the protrusion 60 and the conductive member 20 when viewed in the thickness direction is preferably 10 mm or less, and more preferably 5 mm or less. In addition, the protrusion 60 and the conductive member 20 are preferably separated, and for example, the shortest distance D6 can be 0.01 mm or more, and preferably 0.1 mm or more.

[0192] In addition, in the case where the protrusion 60 is provided, instead of the first exhaust groove, the second exhaust groove 40b (see Figure 6 ) formed on the first fixing surface can be formed, and the exhaust passage such as the first exhaust hole 40d (see Figure 10 ), the second exhaust hole 40e (see Figure 17 ) can be appropriately formed. Of course, two or more of the first exhaust groove 40a, the second exhaust groove 40b, the third exhaust groove 40c, the first exhaust hole 40d, and the second exhaust hole 40e can be appropriately combined, and for example, as shown in Figure 24 , the first exhaust groove 40a and the second exhaust hole 40e can be combined. In this case, the second exhaust hole 40e can communicate with the exhaust groove 40g provided inside the protrusion 60.

[0193] The number of protrusions 60 can be one as shown in Figures 21-24 , or can be a plurality as shown in Figure 25 . From the viewpoint of effectively exhausting the bubbles generated around the conductive member 20, the number of protrusions 60 is preferably set in cooperation with the number of the conductive member 20 according to the disposition position of the conductive member 20. In addition, in the case where the protrusions are a plurality, as shown in Figure 25As shown, the protrusions are connected to each other by connecting member 61. By connecting them by connecting member 61, the fixing member 30 is engaged with the metal terminal 10 while the connecting member 61 is supported, thereby allowing pressure to be applied collectively to the vicinity of the multiple protrusions 60.

[0194] Furthermore, the metal terminal 10 does not necessarily have to be flat; for example, it can also be a combination of inclined surfaces forming a second main surface 12, which is the opposite side of the first main surface 11. For example... Figure 26 As shown, the second main surface 12 may have a first inclined surface 12A and a second inclined surface 12B, and the first inclined surface 12A and the second inclined surface 12B are moved away from the first main surface 11X along with the central protrusion 60. Furthermore, in the above-described embodiments 1 to 6, the metal terminal 10 does not necessarily have to be flat; for example, the second main surface 12 may also be composed of a combination of inclined surfaces.

[0195] The metal terminal 10 having the protrusion 60 can be formed by bending and casting. For example, in bending, it is possible to bend the plate used to form the metal terminal. Figures 21-25 As shown, an venting groove 40g is formed inside the protrusion 60, connecting to the end of the metal terminal 10. Additionally, according to casting forming, as... Figure 26 As shown, the metal terminal 10 can be easily formed in shapes other than flat plates.

[0196] According to the seventh embodiment of the present invention, the connecting member 1g and the connecting structure 2g have a protrusion 60 on the second main surface 12 of the metal terminal 10, which effectively discharges air bubbles generated on the fixing member 30. Because the connecting member 1g and the connecting structure 2g effectively discharge air bubbles, the air bubbles will not remain on the fixing member 30, and the metal terminal 10 can be reliably and easily fixed to the connected member 100 while the conductive member 20 is compressed.

[0197] [Eighth Implementation]

[0198] like Figure 27 As shown, in the connecting member 1h of the eighth embodiment, the portion where the first main surface 11 of the metal terminal 10 contacts the conductive member 20 is convex 70, which differs from the connecting members of the above embodiments. Hereinafter, the differences between the eighth embodiment and the first embodiment will be described. Furthermore, in the following descriptions of different embodiments, members having the same structure will be marked with the same reference numerals.

[0199] The convex 70 is a convex portion having a portion on the first main surface 11 of the metal terminal 10, which contacts the conductive member 20, as an apex. When the connecting member 1h is attached to the connected member 100, the convex portion 70 becomes a starting point of pressing the conductive member 20. Therefore, by pressing from the second main surface 12 side by the connecting member 1h, the pressure is concentrated on the convex portion 70, and the conductive member 20 is easily pressed to the connected member 100. Therefore, by appropriately compressing the conductive member 20, the connecting member 1h is easily fixed to the connected member 100.

[0200] The number of the convex portions 70 can be one or plural. From the viewpoint of forming a state in which the conductive member 20 is effectively compressed, the number of the convex portions 70 is preferably set in correspondence with the number of the conductive members 20, according to the arrangement positions of the conductive members 20.

[0201] The shape of the convex portion 70 is not particularly limited, and as shown in FIG. 6, the apex can be flat, but the apex can also be curved. The convex portion 70 can be formed by bending and molding, or the like. Figure 27

[0202] In the case where the convex 70 is provided, any of the above-described exhaust passages 40 can be provided, and for example, as shown in FIG. 5, a structure in which the first exhaust hole 40d is provided in the metal terminal 10 is shown, but as long as at least one of the first exhaust hole 40d, the second exhaust hole 40e, and the first to third exhaust grooves 40a, 40b, and 40c is provided, various forms can be adopted. Figure 27

[0203] According to the connecting member 1h and the connecting structure 2h of the eighth embodiment of the present application, by having the convex portion 70 on the first main surface 11 of the metal terminal 10, a state in which the conductive member 20 is compressed can be easily formed. In addition, bubbles can be exhausted by the exhaust passage 40 without remaining on the fixing member 30.

[0204] [Other Embodiments]

[0205] In the above description, as the exhaust passage 40, examples in which the first exhaust groove 40a (first embodiment), the second exhaust groove 40b (second embodiment), the third exhaust groove 40c (third embodiment), the first exhaust hole 40d (fourth embodiment), the second exhaust hole 40e (fifth embodiment), and the bottomed hole 40f (sixth embodiment) are provided are shown, and they can be appropriately combined. For example, as shown in FIG. 7, a connecting member 1i and a connecting structure 2i in which the first exhaust groove 40a (first embodiment) and the second exhaust groove 40b (second embodiment) are combined can be adopted. In addition, as shown in FIG. 8, a connecting member 1j and a connecting structure 2j in which the first exhaust groove 40a (first embodiment), the second exhaust groove 40b (second embodiment), and the third exhaust groove 40c (third embodiment) are combined can be adopted. Figure 28 Figure 29 ​​​As the connection member 1j and the connection structure 2j shown, a mode in which the second exhaust groove 40b (second embodiment) and the third exhaust groove 40c (third embodiment) are combined can be adopted.

[0206] In addition, a mode in which the protrusion 60 is provided on the second main surface 12 of the metal terminal 10 (seventh embodiment) and a mode in which the protrusion 70 is provided on the first main surface 11 of the metal terminal 10 (eighth embodiment) are shown separately, but a mode in which they are combined can also be adopted.

[0207] That is, each of the embodiments shown in the above description can be appropriately combined, and all can be combined.

[0208] Further, in each of the embodiments described above, the fixing member 30 and the conductive member 20 are joined by the connection member 50, but the connection member 50 can be omitted. In the case where the connection member 50 is omitted, the fixing member 30 is directly joined to the conductive member 20, whereby the conductive member 20 and the fixing member 30 can be integrated. However, the fixing member 30 and the conductive member 20 are not necessarily integrated, and for example, the conductive member 20 and the fixing member 30 can be separately attached to the metal terminal 10 to produce the connection member.

[0209] Embodiments

[0210] The present application will be described in more detail by embodiments, but the present application is in no way limited by these examples.
