Description

絶縁部材、及び、導電性部材の取付構造Insulating member and conductive member mounting structure
この発明は、絶縁部材、及び、導電性部材の取付構造に関する。 The present invention relates to an insulating member and a mounting structure for a conductive member.
従来、ボルト及びナットによって二つの導電性部材を互いに固定する際、二つの導電性部材がボルト及びナットを介して導通することを防ぐために、ボルトが挿入される導電性部材の貫通孔に筒状の絶縁部材を嵌め込むことが知られている。 Conventionally, when two conductive members are fixed to each other with bolts and nuts, a cylindrical shape is formed in the through hole of the conductive member into which the bolts are inserted in order to prevent the two conductive members from being conducted through the bolts and nuts. It is known to fit the insulating member.
特許文献１には、バッテリー端子のうち重なり合う二つの板部（対向端部）をボルト及びナットによって締め付けて固定する構造において、板部の貫通孔（ボルト孔）に、筒状の絶縁部材を嵌め込む事項が開示されている。特許文献１の絶縁部材は、絶縁性を有する樹脂材料からなる樹脂製筒部の内周に、金属材料からなる金属製筒部（補強層）を形成して構成されている。金属製筒部は、ボルトやナットが樹脂製筒部に触れることを防ぎ、ボルトやナットに対する絶縁部材の耐摩耗性の向上を図っている。 In Patent Document 1, in a structure in which two overlapping plate portions (opposing end portions) of battery terminals are fastened and fixed by bolts and nuts, a cylindrical insulating member is fitted into a through hole (bolt hole) of the plate portion. Matters to be disclosed. The insulating member of Patent Document 1 is configured by forming a metal cylinder portion (reinforcing layer) made of a metal material on the inner periphery of a resin cylinder portion made of an insulating resin material. The metal cylinder portion prevents the bolt or nut from touching the resin cylinder portion, and improves the wear resistance of the insulating member against the bolt or nut.

しかしながら、絶縁部材の一部に金属材料を用いる場合、絶縁部材の重量が重くなるため、好ましくない。
また、樹脂材料及び金属材料からなる絶縁部材を製造する際には、樹脂材料を取り扱う加工装置、及び、金属材料を取り扱う加工装置の両方を用いる必要がある。このため、絶縁部材の加工コストが高くなってしまう、という問題がある。 However, when a metal material is used for a part of the insulating member, the weight of the insulating member is increased, which is not preferable.
Further, when manufacturing an insulating member made of a resin material and a metal material, it is necessary to use both a processing device that handles the resin material and a processing device that handles the metal material. For this reason, there exists a problem that the processing cost of an insulating member will become high.
また、樹脂材料と金属材料との密着性は低いため、従来の絶縁部材では樹脂製筒部と金属製筒部とが剥離しやすい、という問題もある。樹脂製筒部と金属製筒部とが剥離すると、ボルト及びナットによって二つの導電性部材を固定できない可能性があり、好ましくない。 Moreover, since the adhesiveness between the resin material and the metal material is low, there is a problem that the resin cylinder portion and the metal cylinder portion are easily peeled off in the conventional insulating member. If the resin tube portion and the metal tube portion are separated, there is a possibility that the two conductive members cannot be fixed by the bolt and the nut, which is not preferable.
本発明は、軽量化及び加工コストを図ることができ、かつ、二つの筒状部同士の密着性を高めることが可能な絶縁部材、及び、導電性部材の取付構造を提供することを目的とする。 An object of the present invention is to provide an insulating member capable of reducing weight and processing cost, and capable of improving the adhesion between two cylindrical portions, and a mounting structure for a conductive member. To do.
本発明の第一の態様は、絶縁性を有する第一樹脂材料からなる第一筒状部と、絶縁性を有すると共に第一樹脂材料よりも剛性の高い第二樹脂材料からなり、前記第一筒状部の内周に一体に形成された第二筒状部と、を備える絶縁部材である。 A first aspect of the present invention includes a first cylindrical portion made of a first resin material having insulation properties, and a second resin material having insulation properties and higher rigidity than the first resin material. And a second cylindrical part integrally formed on the inner periphery of the cylindrical part.
本発明の第二の態様は、二つの導電性部材を互いに固定する導電性部材の取付構造であって、貫通孔を有する第一導電性部材と、前記第一導電性部材に重ねて配され、貫通孔を有する第二導電性部材と、前記第一導電性部材の貫通孔に嵌め込まれた筒状の絶縁部材と、前記絶縁部材及び前記第二導電性部材の貫通孔に挿通された軸部を有するボルトと、前記ボルトの軸部に噛み合い、前記ボルトの頭部と共に前記絶縁部材及び前記第二導電性部材を挟み込むナットと、を備え、前記絶縁部材が、第一樹脂材料からなる第一筒状部と、第一樹脂材料よりも剛性の高い第二樹脂材料からなり、前記第一筒状部の内周に一体に形成された第二筒状部と、を備える導電性部材の取付構造である。 A second aspect of the present invention is a conductive member mounting structure for fixing two conductive members to each other, and the first conductive member having a through hole and the first conductive member are arranged to overlap each other. A second conductive member having a through hole, a cylindrical insulating member fitted in the through hole of the first conductive member, and a shaft inserted into the through hole of the insulating member and the second conductive member And a nut that meshes with the shaft of the bolt and sandwiches the insulating member and the second conductive member together with the head of the bolt, and the insulating member is made of a first resin material. An electrically conductive member comprising: a cylindrical portion; and a second cylindrical portion made of a second resin material having higher rigidity than the first resin material and integrally formed on the inner periphery of the first cylindrical portion. It is a mounting structure.
本発明によれば、絶縁部材を構成する二つの筒状部がいずれも樹脂材料からなるため、絶縁部材の軽量化、及び、絶縁部材の加工コスト削減を図ることができる。また、二つの筒状部がいずれも樹脂材料からなることで、二つの筒状部同士の密着性を高めることができる。すなわち、二つの筒状部が剥離することを好適に抑制できる。
また、本発明によれば、一方の導電性部材の貫通孔に絶縁部材を嵌め込んだ状態で、二つの導電性部材をボルト及びナットで固定する際に、ボルトやナットを剛性の高い第二筒状部に積極的に接触させることで、ボルトやナットが剛性の低い第一筒状部に触れることを抑制できる。これにより、ボルトやナットに対する絶縁部材の耐摩耗性を確保することができる。 According to the present invention, since the two cylindrical portions constituting the insulating member are both made of a resin material, the weight of the insulating member can be reduced and the processing cost of the insulating member can be reduced. Moreover, the adhesiveness of two cylindrical parts can be improved because both two cylindrical parts consist of resin materials. That is, it can suppress suitably that two cylindrical parts peel.
In addition, according to the present invention, when the two conductive members are fixed with the bolt and the nut in a state where the insulating member is fitted in the through hole of the one conductive member, the bolt and the nut are attached to the second high rigidity member. By positively contacting the tubular portion, it is possible to prevent the bolt or nut from touching the first tubular portion having low rigidity. Thereby, the abrasion resistance of the insulation member with respect to a volt | bolt and a nut is securable.

各導電性部材１，２の形状や寸法は任意であってよい。本実施形態では、二つの導電性部材１，２が、いずれも板状に形成され、これらの板厚方向に重ねて配されている。このため、各導電性部材１，２において、貫通孔１１，２１の両端が開口する各導電性部材１，２の一対の開口面１２，１３，２２，２３は、それぞれ平坦に形成されている。 The shapes and dimensions of the conductive members 1 and 2 may be arbitrary. In the present embodiment, the two conductive members 1 and 2 are both formed in a plate shape and are arranged so as to overlap in the plate thickness direction. For this reason, in each conductive member 1, the pair of opening surfaces 12, 13, 22, and 23 of each conductive member 1 and 2 in which both ends of the through holes 11 and 21 open are formed flat. .
絶縁部材３は、筒状に形成され、第一導電性部材１の貫通孔１１に嵌め込まれる。
図１～３に示すように、絶縁部材３は、第一筒状部３１及び第二筒状部３２を備える。本実施形態において、二つの筒状部３１，３２はいずれも固い。各筒状部３１，３２は、例えば弾性率が非常に高く、外力が付与されても弾性変形しない又は微小に弾性変形する程度に固い。 The insulating member 3 is formed in a cylindrical shape and is fitted into the through hole 11 of the first conductive member 1.
As shown in FIGS. 1 to 3, the insulating member 3 includes a first cylindrical portion 31 and a second cylindrical portion 32. In the present embodiment, the two cylindrical portions 31 and 32 are both hard. Each of the cylindrical portions 31 and 32 has, for example, a very high elastic modulus and is hard enough to be not elastically deformed or slightly elastically deformed even when an external force is applied.
第一筒状部３１は、絶縁性を有する樹脂材料（第一樹脂材料）からなる。
第一筒状部３１の外周は、少なくとも第一導電性部材１の貫通孔１１に対応する形状に形成されていればよい。第一筒状部３１の外周は、絶縁部材３の軸方向から見た平面視で、多角形状などの任意の形状に形成されてよい。本実施形態において、第一筒状部３１の外周は平面視で円形状に形成されている。第一筒状部３１の内周は、任意の形状に形成されてよいが、本実施形態では平面視で円形状に形成されている。すなわち、本実施形態の第一筒状部３１は、円筒状に形成されている。 The first cylindrical portion 31 is made of an insulating resin material (first resin material).
The outer periphery of the 1st cylindrical part 31 should just be formed in the shape corresponding to the through-hole 11 of the 1st electroconductive member 1 at least. The outer periphery of the first cylindrical portion 31 may be formed in an arbitrary shape such as a polygonal shape in a plan view viewed from the axial direction of the insulating member 3. In the present embodiment, the outer periphery of the first cylindrical portion 31 is formed in a circular shape in plan view. The inner periphery of the first cylindrical portion 31 may be formed in an arbitrary shape, but in the present embodiment, it is formed in a circular shape in plan view. That is, the first cylindrical portion 31 of the present embodiment is formed in a cylindrical shape.
第一筒状部３１の外周は、例えば絶縁部材３を第一導電性部材１の貫通孔１１に容易に嵌め込むことができるように形成されてもよい。具体的には、第一筒状部３１の外周に、嵌め込み用の突起（不図示）が形成されてもよい。突起は、第一筒状部３１の軸方向に延びて形成されると共に、第一筒状部３１の周方向に間隔をあけて複数配列されているとよい。第一筒状部３１の径方向における各突起の突出高さは、例えば、軸方向における第一筒状部３１の第一端部３３から第二端部３４に向かうにしたがって小さくなっていてもよい。 The outer periphery of the first cylindrical portion 31 may be formed so that, for example, the insulating member 3 can be easily fitted into the through hole 11 of the first conductive member 1. Specifically, a fitting projection (not shown) may be formed on the outer periphery of the first cylindrical portion 31. The protrusions may be formed so as to extend in the axial direction of the first cylindrical portion 31, and a plurality of protrusions may be arranged at intervals in the circumferential direction of the first cylindrical portion 31. Even if the protrusion height of each protrusion in the radial direction of the first cylindrical portion 31 decreases from the first end portion 33 of the first cylindrical portion 31 toward the second end portion 34 in the axial direction, for example. Good.
第一筒状部３１の外周に上記の突起が形成されている場合には、絶縁部材３を第一筒状部３１の第二端部３４側から第一導電性部材１の貫通孔１１に挿入することで、絶縁部材３を第一導電性部材１の貫通孔１１に容易に挿入できると共に、絶縁部材３を第一導電性部材１の貫通孔１１に嵌め込むことができる。 When the projection is formed on the outer periphery of the first cylindrical portion 31, the insulating member 3 is moved from the second end 34 side of the first cylindrical portion 31 to the through hole 11 of the first conductive member 1. By inserting, the insulating member 3 can be easily inserted into the through hole 11 of the first conductive member 1, and the insulating member 3 can be fitted into the through hole 11 of the first conductive member 1.
本実施形態の第一筒状部３１は、上記した形状の第一筒部本体３５に加え、第一フランジ部３６も含む。第一フランジ部３６は、軸方向における第一筒部本体３５の第一端部３３から、径方向において第一筒状部３１本体の外側に延びている。第一フランジ部３６の形状は特に限定されないが、本実施形態の第一フランジ部３６は環状に形成されている。 The first cylindrical portion 31 of the present embodiment includes a first flange portion 36 in addition to the first cylindrical portion main body 35 having the above-described shape. The first flange portion 36 extends from the first end portion 33 of the first cylindrical portion main body 35 in the axial direction to the outside of the first cylindrical portion 31 main body in the radial direction. Although the shape of the 1st flange part 36 is not specifically limited, The 1st flange part 36 of this embodiment is formed in cyclic | annular form.
第二筒状部３２は、絶縁性を有すると共に第一樹脂材料（第一筒状部３１を構成する樹脂材料）よりも剛性の高い第二樹脂材料からなる。第二筒状部３２は、例えば、ボルト４及びナット５による締め付けトルクに耐え得る程度の剛性を有している。
第二筒状部３２は、第一筒状部３１の内周に一体に形成されている。すなわち、第二筒状部３２の外周は第一筒状部３１の内周に対応する形状に形成され、第二筒状部３２の外周が第一筒状部３１の内周に密着している。本実施形態において、第二筒状部３２の外周は平面視で円形状に形成されている。 The second cylindrical portion 32 is made of a second resin material having insulation and higher rigidity than the first resin material (the resin material constituting the first cylindrical portion 31). The second cylindrical portion 32 has a rigidity that can withstand the tightening torque by the bolt 4 and the nut 5, for example.
The second cylindrical part 32 is formed integrally with the inner periphery of the first cylindrical part 31. That is, the outer periphery of the second cylindrical portion 32 is formed in a shape corresponding to the inner periphery of the first cylindrical portion 31, and the outer periphery of the second cylindrical portion 32 is in close contact with the inner periphery of the first cylindrical portion 31. Yes. In the present embodiment, the outer periphery of the second cylindrical portion 32 is formed in a circular shape in plan view.
第二筒状部３２の内周は、少なくともボルト４の軸部４１を挿通可能な形状に形成されていれば、任意の形状に形成されてよい。本実施形態において、第二筒状部３２の内周は平面視で円形状に形成されている。すなわち、本実施形態の第二筒状部３２は、円筒状に形成されている。
本実施形態において、軸方向における第二筒状部３２の両端部は、軸方向における第一筒状部３１の両端から突出している。 The inner circumference of the second cylindrical portion 32 may be formed in an arbitrary shape as long as it is formed in a shape that allows at least the shaft portion 41 of the bolt 4 to be inserted. In the present embodiment, the inner periphery of the second cylindrical portion 32 is formed in a circular shape in plan view. That is, the second cylindrical portion 32 of the present embodiment is formed in a cylindrical shape.
In the present embodiment, both end portions of the second tubular portion 32 in the axial direction protrude from both ends of the first tubular portion 31 in the axial direction.
上記した絶縁部材３は、図１に示すように、第一導電性部材１の貫通孔１１に嵌め込まれている。これにより、絶縁部材３は第一導電性部材１に固定されている。
本実施形態において、絶縁部材３は、第一筒状部３１の第二端部３４側から第一導電性部材１の貫通孔１１に挿入されている。そして、第一筒状部３１の第一フランジ部３６は、貫通孔１１が開口する第一導電性部材１の開口面１２に当接している。 As shown in FIG. 1, the insulating member 3 described above is fitted in the through hole 11 of the first conductive member 1. Thereby, the insulating member 3 is fixed to the first conductive member 1.
In the present embodiment, the insulating member 3 is inserted into the through hole 11 of the first conductive member 1 from the second end 34 side of the first cylindrical portion 31. And the 1st flange part 36 of the 1st cylindrical part 31 is contact | abutted to the opening surface 12 of the 1st electroconductive member 1 in which the through-hole 11 opens.
より具体的に説明すれば、絶縁部材３は、第一導電性部材１の貫通孔１１の両端が開口する第一導電性部材１の一対の開口面１２，１３のうち第二導電性部材２に対向する第一導電性部材１の第一開口面１２側から、第一導電性部材１の貫通孔１１に挿入されている。このため、第一筒状部３１の第一フランジ部３６は第一導電性部材１の第一開口面１２に当接している。
第一フランジ部３６が第一導電性部材１の第一開口面１２に当接することで、貫通孔１１の貫通方向（軸方向）において絶縁部材３を第一導電性部材１に対して容易に位置決めできる。 More specifically, the insulating member 3 includes the second conductive member 2 of the pair of opening surfaces 12 and 13 of the first conductive member 1 in which both ends of the through hole 11 of the first conductive member 1 are open. Is inserted into the through-hole 11 of the first conductive member 1 from the first opening surface 12 side of the first conductive member 1. For this reason, the first flange portion 36 of the first cylindrical portion 31 is in contact with the first opening surface 12 of the first conductive member 1.
Since the first flange portion 36 abuts on the first opening surface 12 of the first conductive member 1, the insulating member 3 can be easily moved with respect to the first conductive member 1 in the through direction (axial direction) of the through hole 11. Can be positioned.
絶縁部材３を第一導電性部材１の貫通孔１１に嵌め込んだ状態では、軸方向における第二筒状部３２の両端が、貫通孔１１の貫通方向（軸方向）における第一導電性部材１の両端から突出している。図示例では、軸方向における第一筒状部３１の両端も、同様にして第一導電性部材１の両端から突出しているが、これに限ることはない。 In a state where the insulating member 3 is fitted in the through hole 11 of the first conductive member 1, both ends of the second cylindrical portion 32 in the axial direction are the first conductive member in the through direction (axial direction) of the through hole 11. 1 protrudes from both ends. In the illustrated example, both ends of the first cylindrical portion 31 in the axial direction also protrude from both ends of the first conductive member 1 in the same manner, but are not limited thereto.
第一導電性部材１の第一開口面１２から突出する絶縁部材３の第二筒状部３２の端部は、第一導電性部材１に対向する第二導電性部材２の第一開口面２２に当接している。このため、二つの導電性部材１，２を重ね合せた状態において、二つの導電性部材１，２は、その配列方向（絶縁部材３の軸方向）互いに間隔をあけて位置している。 The end of the second cylindrical portion 32 of the insulating member 3 protruding from the first opening surface 12 of the first conductive member 1 is the first opening surface of the second conductive member 2 facing the first conductive member 1. 22 abuts. For this reason, in the state where the two conductive members 1 and 2 are overlapped, the two conductive members 1 and 2 are positioned at intervals from each other in the arrangement direction (the axial direction of the insulating member 3).
ボルト４及びナット５は、いずれも導電性を有し、絶縁部材３が取り付けられた第一導電性部材１と、これに重ねて配された第二導電性部材２とを締め付け固定する。以下、この点についてより具体的に説明する。 Both the bolt 4 and the nut 5 have conductivity, and fasten and fix the first conductive member 1 to which the insulating member 3 is attached and the second conductive member 2 disposed so as to overlap therewith. Hereinafter, this point will be described more specifically.
ボルト４の軸部４１は、絶縁部材３及び第二導電性部材２の貫通孔２１に挿通されている。ボルト４の軸部４１は、例えば、第二導電性部材２側から第二導電性部材２の貫通孔２１、絶縁部材３に順番に挿入されてもよい。本実施形態では、第一導電性部材１側から絶縁部材３、第二導電性部材２の貫通孔２１に順番に挿入されている。ボルト４の頭部４２は、第一導電性部材１の第二開口面１３から突出する絶縁部材３の第二筒状部３２の端部に当接している。このため、ボルト４の頭部４２は、第一導電性部材１に対して絶縁部材３の軸方向に間隔をあけて位置し、第一導電性部材１に接触しない。また、本実施形態において、ボルト４の頭部４２は第一筒状部３１にも接触しない。ボルト４の軸部４１の先端部は、第二導電性部材２の第二開口面２３から突出している。 The shaft portion 41 of the bolt 4 is inserted through the through hole 21 of the insulating member 3 and the second conductive member 2. For example, the shaft portion 41 of the bolt 4 may be inserted into the through hole 21 and the insulating member 3 of the second conductive member 2 in this order from the second conductive member 2 side. In the present embodiment, the insulating member 3 and the second conductive member 2 are inserted in order from the first conductive member 1 side into the through hole 21. The head portion 42 of the bolt 4 is in contact with the end portion of the second cylindrical portion 32 of the insulating member 3 protruding from the second opening surface 13 of the first conductive member 1. For this reason, the head portion 42 of the bolt 4 is positioned at an interval in the axial direction of the insulating member 3 with respect to the first conductive member 1, and does not contact the first conductive member 1. In the present embodiment, the head portion 42 of the bolt 4 does not contact the first cylindrical portion 31. The front end portion of the shaft portion 41 of the bolt 4 protrudes from the second opening surface 23 of the second conductive member 2.
ナット５は、ボルト４の軸部４１に噛み合い、ボルト４の頭部４２と共に絶縁部材３及び第二導電性部材２を挟み込む。これにより、二つの導電性部材１，２が互いに固定されている。本実施形態において、ナット５は、第二導電性部材２の第二開口面２３から突出しているボルト４の軸部４１の先端部に噛み合い、第二導電性部材２の第二開口面２３に当接する。 The nut 5 meshes with the shaft portion 41 of the bolt 4 and sandwiches the insulating member 3 and the second conductive member 2 together with the head portion 42 of the bolt 4. Thereby, the two electroconductive members 1 and 2 are mutually fixed. In this embodiment, the nut 5 meshes with the tip end portion of the shaft portion 41 of the bolt 4 protruding from the second opening surface 23 of the second conductive member 2, and engages with the second opening surface 23 of the second conductive member 2. Abut.
以上のように構成される本実施形態の取付構造では、ボルト４及びナット５と第一導電性部材１（特に貫通孔１１）との間に絶縁部材３が介在しているため、二つの導電性部材１，２がボルト４及びナット５を介して導通することを好適に抑制できる。 In the mounting structure of the present embodiment configured as described above, the insulating member 3 is interposed between the bolt 4 and the nut 5 and the first conductive member 1 (particularly, the through hole 11). The conductive members 1 and 2 can be suitably prevented from conducting via the bolt 4 and the nut 5.
本実施形態によれば、絶縁部材３の二つの筒状部３１，３２がいずれも樹脂材料からなる。このため、絶縁部材３の軽量化、及び、絶縁部材３の加工コスト削減を図ることができる。また、剛性が低い第一筒状部３１は、安価な樹脂材料で成形できるため、絶縁部材３の加工コストをさらに削減できる。
また、二つの筒状部３１，３２がいずれも樹脂材料からなることで、二つの筒状部３１，３２同士の密着性を高めることができる。すなわち、二つの筒状部３１，３２が剥離することを好適に抑制できる。したがって、二つの導電性部材１，２の固定不良を好適に抑えることができる。 According to this embodiment, the two cylindrical portions 31 and 32 of the insulating member 3 are both made of a resin material. For this reason, the weight reduction of the insulating member 3 and the processing cost reduction of the insulating member 3 can be aimed at. Moreover, since the 1st cylindrical part 31 with low rigidity can be shape | molded with an inexpensive resin material, the processing cost of the insulating member 3 can further be reduced.
Moreover, the adhesiveness of two cylindrical parts 31 and 32 can be improved because both the cylindrical parts 31 and 32 consist of resin materials. That is, it can suppress suitably that the two cylindrical parts 31 and 32 peel. Therefore, fixing failure of the two conductive members 1 and 2 can be suitably suppressed.
また、本実施形態によれば、第二筒状部３２の剛性が第一筒状部３１よりも高い。このため、ボルト４及び第二導電性部材２に剛性の高い第二筒状部３２に積極的に接触させることで、ボルト４及び第二導電性部材２が剛性の低い第一筒状部３１に触れることを抑制できる。
特に、本実施形態では、第二筒状部３２の両端部が第一筒状部３１の両端から突出している。このため、絶縁部材３のうち剛性の高い第二筒状部３２のみをボルト４及び第二導電性部材２に接触させ、剛性の低い第一筒状部３１がボルト４及び第二導電性部材２に接触することを防止できる。これにより、ボルト４や第二導電性部材２などに対する絶縁部材３の耐摩耗性を確保することができる。 Further, according to the present embodiment, the rigidity of the second cylindrical portion 32 is higher than that of the first cylindrical portion 31. For this reason, the bolt 4 and the second conductive member 2 are positively brought into contact with the second cylindrical portion 32 having high rigidity, so that the bolt 4 and the second conductive member 2 have low rigidity. Touching can be suppressed.
In particular, in the present embodiment, both end portions of the second tubular portion 32 protrude from both ends of the first tubular portion 31. For this reason, only the highly rigid 2nd cylindrical part 32 is made to contact the volt | bolt 4 and the 2nd electroconductive member 2 among the insulating members 3, and the 1st cylindrical part 31 with a low rigidity is the volt | bolt 4 and the 2nd electroconductive member. 2 can be prevented from contacting. Thereby, the abrasion resistance of the insulating member 3 with respect to the volt | bolt 4, the 2nd electroconductive member 2, etc. is securable.
また、第二筒状部３２の両端部が第一筒状部３１の両端から突出していることで、絶縁部材３のうち剛性の高い第二筒状部３２だけが、ボルト４の頭部４２とナット５との間に挟み込まれる。このため、二つの導電性部材１，２をボルト４及びナット５によって締め付け固定しても、絶縁部材３が軸方向に変形することを効果的に抑制できる。したがって、二つの導電性部材１，２をボルト４及びナット５によって締め付け固定する際に生じる軸力を好適に保持できる。 In addition, since both end portions of the second tubular portion 32 protrude from both ends of the first tubular portion 31, only the rigid second tubular portion 32 of the insulating member 3 is the head portion 42 of the bolt 4. And the nut 5. For this reason, even if the two conductive members 1 and 2 are fastened and fixed by the bolt 4 and the nut 5, it is possible to effectively suppress the insulating member 3 from being deformed in the axial direction. Therefore, the axial force generated when the two conductive members 1 and 2 are fastened and fixed by the bolt 4 and the nut 5 can be suitably maintained.
第一実施形態において、絶縁部材３は、例えば、第二導電性部材２に対向しない第一導電性部材１の第二開口面１３側から、第一導電性部材１の貫通孔１１に挿入されてもよい。 In 1st embodiment, the insulating member 3 is inserted in the through-hole 11 of the 1st electroconductive member 1 from the 2nd opening surface 13 side of the 1st electroconductive member 1 which does not oppose the 2nd electroconductive member 2, for example. May be.
