<導電部材について>
以下、実施形態に係る導電部材について説明する。図1は第1導電部材22Aと第2導電部材22Bとを開いた状態を示す分解図であり、図2は第1導電部材22Aと第2導電部材22Bとを組合わせた状態を示す正面図であり、図3は第1導電部材22Aと第2導電部材22Bとを組合わせた状態を示す側面図である。
<About conductive members>
Hereinafter, the conductive member according to the embodiment will be described. FIG. 1 is an exploded view showing a state where the first conductive member 22A and the second conductive member 22B are opened, and FIG. 2 is a front view showing a state where the first conductive member 22A and the second conductive member 22B are combined. FIG. 3 is a side view showing a state in which the first conductive member 22A and the second conductive member 22B are combined.

この第1導電部材22Aと第2導電部材22Bは、それぞれ相手側接続部材に電気的及び機械的に接続される導電部材としての電気部品である。ここで、第1導電部材22Aと第2導電部材22Bが相手側接続部材に機械的に接続されるとは、それらの部材が相手側接続部材に対して離れることなく接触した状態に維持されることをいい、好ましくは、それらの部材が相手側接続部材に対して一定位置において接した状態に維持されることをいう。   The first conductive member 22A and the second conductive member 22B are electrical components as conductive members that are electrically and mechanically connected to the mating connection member. Here, when the first conductive member 22A and the second conductive member 22B are mechanically connected to the mating connection member, the members are maintained in contact with the mating connection member without leaving. Preferably, it means that those members are kept in contact with the mating connection member at a fixed position.

例えば、第1導電部材22Aと第2導電部材22Bは、自動車等の車両に搭載される部品である。例えば、車両に搭載された状態で、本第1導電部材22Aと第2導電部材22Bとは、被覆電線を覆うと共に、車両に搭載された相手側接続部材(金属筐体等)に電気的及び機械的に接続される。相手側接続部材が、車両ボディ又は電気機器の筐体であり、基準電位体である場合、本第1導電部材22Aと第2導電部材22Bは、接地される。これにより、被覆電線を電磁シールドすることができる。また、例えば、本第1導電部材22Aと第2導電部材22Bが、2つの相手側接続部材のそれぞれに接続される。これにより、本第1導電部材22Aと第2導電部材22Bは、2つの相手側接続部材を電気的に接続することができる。   For example, the first conductive member 22A and the second conductive member 22B are components mounted on a vehicle such as an automobile. For example, the first conductive member 22A and the second conductive member 22B cover the covered electric wire and are electrically connected to a mating connection member (such as a metal housing) mounted on the vehicle while mounted on the vehicle. Mechanically connected. When the counterpart connection member is a vehicle body or a housing of an electric device and is a reference potential body, the first conductive member 22A and the second conductive member 22B are grounded. Thereby, the covered electric wire can be electromagnetically shielded. Further, for example, the first conductive member 22A and the second conductive member 22B are connected to each of the two mating connection members. Thus, the first conductive member 22A and the second conductive member 22B can electrically connect the two mating connection members.

本実施形態では、第1導電部材22Aと第2導電部材22Bとが、被覆電線を覆った状態で、2つの相手側接続部材に電気的及び機械的に接続される例、すなわち、電磁シールド具及び配線材として用いられる例で説明する。もっとも、第1導電部材22Aと第2導電部材22Bは、電磁シールドの用途のみ、或は、配線材の用途のみで用いられてもよい。また、第1導電部材22Aと第2導電部材22Bとは、それぞれが被覆電線の周りの一方を覆うことができる。このため、第1導電部材22Aと第2導電部材22Bとは、それぞれ単独で、電磁シールドの用途のみ、配線材の用途のみ、或は、それらの両用途で用いることができる。   In the present embodiment, an example in which the first conductive member 22A and the second conductive member 22B are electrically and mechanically connected to the two mating connection members in a state where the covered electric wire is covered, that is, an electromagnetic shielding tool. An example used as a wiring material will be described. However, the first conductive member 22A and the second conductive member 22B may be used only for electromagnetic shielding or only for wiring material. Further, each of the first conductive member 22A and the second conductive member 22B can cover one around the covered electric wire. For this reason, the first conductive member 22A and the second conductive member 22B can each be used alone, only for electromagnetic shielding, only for wiring, or both.

第1導電部材22Aは、1枚の金属板を加工することによって形成された導電部材である。   The first conductive member 22A is a conductive member formed by processing one metal plate.

金属板30(図4参照)は、ステンレス、アルミニウム、アルミニウム合金、銅、銅合金等の板材である。当所の厚みは、接続部26A及び形状維持部28Aを形成するのに適した厚み寸法に形成されている。金属板30には、錫メッキ、亜鉛メッキ等が施されていてもよい。   The metal plate 30 (see FIG. 4) is a plate material such as stainless steel, aluminum, aluminum alloy, copper, or copper alloy. The thickness of this place is formed in a thickness dimension suitable for forming the connecting portion 26A and the shape maintaining portion 28A. The metal plate 30 may be subjected to tin plating, zinc plating, or the like.

第1導電部材22Aは、方形状部分22A1と、方形状部分22A1の両側部にその一方主面側に立上がるように形成された一対の側壁部22A2と、当該一対の側壁部のそれぞれの先端部から外方に向けて延出する一対の縁部22A3とを備えた構成とされている。なお、側壁部22A2、縁部22A3の一方又は両方が省略されてもよい。   The first conductive member 22A includes a rectangular portion 22A1, a pair of side wall portions 22A2 formed on both side portions of the rectangular portion 22A1 so as to rise to one main surface side thereof, and respective tips of the pair of side wall portions. It is set as the structure provided with a pair of edge part 22A3 extended toward the outward from a part. One or both of the side wall portion 22A2 and the edge portion 22A3 may be omitted.

第1導電部材22Aのうち両端部間の領域(図1の上側端部と下側端部との間の領域)が、面状導電部24Aであり、曲げ可能に形成されている。面状導電部24Aは、縁部22A3を除き、他と重ね合されず、単層の状態のままとされる。   A region between both end portions of the first conductive member 22A (a region between the upper end portion and the lower end portion in FIG. 1) is a planar conductive portion 24A and is formed to be bendable. The planar conductive portion 24A is not overlapped with the others except the edge portion 22A3, and remains in a single layer state.

この面状導電部24Aは、上記金属板30の一部にその厚み方向に沿った圧力を加えることによって、その他の接続部26A及び形状維持部28Aの厚み寸法よりも小さく厚み寸法となるように形成されており、これにより、曲げ可能とされている。   The planar conductive portion 24A has a thickness dimension smaller than the thickness dimensions of the other connecting portions 26A and the shape maintaining portions 28A by applying pressure along the thickness direction to a part of the metal plate 30. It is formed so that it can be bent.

面状導電部24Aの厚みは、用いられる金属によって異なるが、手作業によって曲げ可能な程度の大きさに形成されることが好ましい。また、本実施形態では、第1導電部材22Aと第2導電部材22Bとが組合わされた状態で使用され、それらが部分的に2層に重ね合される。このため、面状導電部24Aの厚み寸法は、2層に重ね合された状態でも、手作業によって曲げ可能な程度の大きさに設定されていることが好ましい。   The thickness of the planar conductive portion 24A varies depending on the metal used, but is preferably formed to a size that can be bent manually. In the present embodiment, the first conductive member 22A and the second conductive member 22B are used in a combined state, and they are partially overlapped in two layers. For this reason, it is preferable that the thickness dimension of the planar conductive portion 24A is set to such a size that it can be bent manually even in the state of being overlapped on two layers.

さらに、第1導電部材22Aのうち方形状部分22A1及び一対の側壁部22A2の両端部が、形状維持部28Aに形成されている。形状維持部28Aは、上記方形状部分22A1の端部に連なる帯状部分と、上記一対の側壁部22A2の両端部に連なり、前記帯状部分の両端部からその一方主面側に立上がる立上部とを有する。この形状維持部28Aによって、面状導電部24Aが被覆電線を収容可能な形状、すなわち、方形状部分22A1の両側部から一対の側壁部22A2が立上がる形状が維持されている。   Furthermore, both ends of the rectangular portion 22A1 and the pair of side wall portions 22A2 of the first conductive member 22A are formed in the shape maintaining portion 28A. The shape maintaining portion 28A includes a belt-like portion that is continuous with the end portion of the rectangular portion 22A1, a rising portion that is continuous with both end portions of the pair of side wall portions 22A2, and rises from the both end portions of the belt-like portion toward one main surface side. Have The shape maintaining portion 28A maintains the shape in which the planar conductive portion 24A can accommodate the covered electric wire, that is, the shape in which the pair of side wall portions 22A2 rises from both sides of the rectangular portion 22A1.

また、第1導電部材22Aのうち一対の縁部22A3のそれぞれの両端部が一対の接続部26Aに形成されている。この一対の接続部26Aは、形状維持部28Aの上記一対の立上部の先端部から外方に延出するようにして接続部26Aが繋がっている。この接続部26Aによって、縁部22A3が側壁部22A2の外方に向う姿勢に維持されている。   Further, both end portions of the pair of edge portions 22A3 of the first conductive member 22A are formed in the pair of connection portions 26A. The pair of connection portions 26A is connected to the connection portion 26A so as to extend outward from the tip ends of the pair of upright portions of the shape maintaining portion 28A. By this connecting portion 26A, the edge portion 22A3 is maintained in a posture toward the outside of the side wall portion 22A2.

ここでは、接続部26Aは、縁部22A3の端部に連続する方形板状部分に形成されている。この接続部26Aには、その表裏に貫通する孔26Ahが形成されている。ここでは、孔26Ahは、円形状の孔であり、後述するネジSを挿通可能とされている。   Here, the connecting portion 26A is formed in a rectangular plate-like portion that is continuous with the end portion of the edge portion 22A3. The connecting portion 26A is formed with a hole 26Ah penetrating the front and back. Here, the hole 26Ah is a circular hole through which a screw S described later can be inserted.

上記一対の接続部26A及び形状維持部28Aは、金属板30の外周部に形成され、面状導電部24Aの厚み寸法よりも大きい厚み寸法に形成された部分である。接続部26Aが比較的大きい厚み寸法に形成されることによって、当該接続部26Aに相手側接続部材に接続するのに適した強度を持たせることができる。また、形状維持部28Aが比較的大きい厚み寸法に形成されることによって、面状導電部24Aを、被覆電線を覆うのに適した形状に維持することができる。   The pair of connection portions 26A and the shape maintaining portion 28A are portions formed on the outer peripheral portion of the metal plate 30 and having a thickness dimension larger than the thickness dimension of the planar conductive portion 24A. By forming the connecting portion 26A to have a relatively large thickness dimension, the connecting portion 26A can have strength suitable for connecting to the counterpart connecting member. Further, the shape maintaining portion 28A is formed to have a relatively large thickness, whereby the planar conductive portion 24A can be maintained in a shape suitable for covering the covered electric wire.

第2導電部材22Bは、上記第1導電部材22Aと同様構成とされている。   The second conductive member 22B has the same configuration as the first conductive member 22A.

すなわち、第2導電部材22Bは、方形状部分22B1と、方形状部分22B1の両側部にその一方主面側に立上がるように形成された一対の側壁部22B2と、当該一対の側壁部のそれぞれの先端部から外方に向けて延出する一対の縁部22B3とを備えた構成とされている。なお、側壁部22B2、縁部22B3の一方又は両方が省略されてもよい。   That is, the second conductive member 22B includes a rectangular portion 22B1, a pair of side wall portions 22B2 formed on both side portions of the rectangular portion 22B1 so as to rise on the one main surface side, and each of the pair of side wall portions. It is set as the structure provided with a pair of edge part 22B3 extended toward the outward from the front-end | tip part. One or both of the side wall portion 22B2 and the edge portion 22B3 may be omitted.

第2導電部材22Bのうち両端部間の領域(図1の上側端部と下側端部との間の領域)が、面状導電部24Bであり、曲げ可能に形成されている。面状導電部24Aは、縁部22B3を除き、他と重ね合されず、単層の状態のままとされる。   A region between both end portions of the second conductive member 22B (a region between the upper end portion and the lower end portion in FIG. 1) is a planar conductive portion 24B and is formed to be bendable. The planar conductive portion 24A is not overlapped with the others except the edge portion 22B3, and remains in a single layer state.

また、第2導電部材22Bのうち方形状部分22B1及び一対の側壁部22B2の両端部が、形状維持部28Bに形成されている。形状維持部28Bは、上記方形状部分22B1の端部に連なる帯状部分と、上記一対の側壁部22B2の両端部に連なり、前記帯状部分の両端部からその一方主面側に立上がる立上部とを有する。この形状維持部28Bによって、面状導電部24Aが被覆電線を収容可能な形状、すなわち、方形状部分22B1の両側部から一対の側壁部22B2が立上がる形状が維持されている。   Further, both ends of the rectangular portion 22B1 and the pair of side wall portions 22B2 of the second conductive member 22B are formed in the shape maintaining portion 28B. The shape maintaining portion 28B includes a band-shaped portion that is continuous with the end portion of the rectangular portion 22B1, a rising portion that is continuous with both end portions of the pair of side wall portions 22B2, and rises from the both end portions of the band-shaped portion toward one main surface thereof. Have The shape maintaining portion 28B maintains the shape in which the planar conductive portion 24A can accommodate the covered electric wire, that is, the shape in which the pair of side wall portions 22B2 rises from both side portions of the rectangular portion 22B1.

また、第2導電部材22Bのうち一対の縁部22B3のそれぞれの両端部が一対の接続部26Bに形成されている。この一対の接続部26Bは、形状維持部28Bの上記一対の立上部の先端部から外方に延出するようにして接続部26Bが繋がっている。この接続部26Bによって、縁部22B3が側壁部22B2の外方に向う姿勢に維持されている。   Further, both ends of the pair of edge portions 22B3 of the second conductive member 22B are formed in the pair of connection portions 26B. The pair of connection portions 26B are connected to the connection portions 26B so as to extend outward from the tip portions of the pair of upright portions of the shape maintaining portion 28B. By this connection portion 26B, the edge portion 22B3 is maintained in a posture toward the outside of the side wall portion 22B2.

ここでは、接続部26Bは、縁部22B3の端部に連続する方形板状部分に形成されている。この接続部26Bには、その表裏に貫通する孔26Bhが形成されている。ここでは、孔26Bhは、円形状の孔であり、後述するネジSを挿通可能とされている。   Here, the connecting portion 26B is formed in a rectangular plate-like portion that is continuous with the end portion of the edge portion 22B3. The connecting portion 26B is formed with a hole 26Bh penetrating the front and back. Here, the hole 26Bh is a circular hole through which a screw S described later can be inserted.

上記一対の接続部26B及び形状維持部28Bは、金属板30の外周部に形成され、面状導電部24Bの厚み寸法よりも大きい厚み寸法に形成された部分である。接続部26Bが比較的大きい厚み寸法に形成されることによって、当該接続部26Bに相手側接続部材に接続するのに適した強度を持たせることができる。また、形状維持部28Bが比較的大きい厚み寸法に形成されることによって、面状導電部24Bが被覆電線を覆うのに適した形状に維持することができる。   The pair of connection portions 26B and the shape maintaining portion 28B are portions formed on the outer peripheral portion of the metal plate 30 and having a thickness dimension larger than the thickness dimension of the planar conductive portion 24B. By forming the connecting portion 26B to have a relatively large thickness dimension, the connecting portion 26B can have a strength suitable for connecting to the counterpart connecting member. Further, the shape maintaining portion 28B is formed to have a relatively large thickness, whereby the planar conductive portion 24B can be maintained in a shape suitable for covering the covered electric wire.

<About usage examples of conductive members>
A usage example of the first conductive member 22A and the second conductive member 22B will be described. FIG. 4 is an explanatory view showing a state in the middle of attaching the connector-attached electric wire 50 to the first conductive member 22A and the second conductive member 22B, and FIG. It is explanatory drawing which shows the state by which 2 conductive member 22B was electrically and mechanically connected to the other party connection member 70. FIG.

コネクタ付電線50は、被覆電線52と、コネクタ60とを備えている。   The electric wire with connector 50 includes a covered electric wire 52 and a connector 60.

ここでは、コネクタ付電線50は、複数(ここでは3つ)の被覆電線52備える。各被覆電線52の両端部では、被覆部が除去され、芯線部が露出している。各芯線部に端子54が接続されている。芯線部と端子54との接続は、圧着、超音波溶接、半田付等により行われる。コネクタ付電線は、被覆電線を1つのみの備えていてもよい。   Here, the electric wire with connector 50 includes a plurality (here, three) of covered electric wires 52. At both end portions of each covered electric wire 52, the covering portion is removed and the core wire portion is exposed. A terminal 54 is connected to each core part. The connection between the core wire portion and the terminal 54 is performed by crimping, ultrasonic welding, soldering, or the like. The electric wire with connector may include only one covered electric wire.

コネクタ60は、上記複数の被覆電線52の両端部において、それぞれ被覆電線52の端部及び端子54を並列状態に保持する部分である。コネクタ60は、被覆電線52の端部及び端子54をインサート部品とする金型成形によって形成された合成樹脂製の部分である。   The connector 60 is a portion that holds the end portions of the covered electric wires 52 and the terminals 54 in parallel at both ends of the plurality of covered electric wires 52. The connector 60 is a synthetic resin portion formed by molding using the end portion of the covered electric wire 52 and the terminal 54 as an insert part.

コネクタ60は、電線保持部62と、端子囲部64とを備えている。   The connector 60 includes an electric wire holding part 62 and a terminal surrounding part 64.

電線保持部62は、長尺状部分に形成されており、この内部に被覆電線52の端部及び端子54の基端部がインサートされている。電線保持部62の一方面側から複数の被覆電線52が並列状に延出しており、この反対側の面から複数の端子54の先端部が並列状に延出している。   The electric wire holding part 62 is formed in an elongated portion, and the end of the covered electric wire 52 and the base end of the terminal 54 are inserted therein. A plurality of covered electric wires 52 extend in parallel from one surface side of the electric wire holding portion 62, and tip portions of the plurality of terminals 54 extend in parallel from the opposite surface.

端子囲部64は、電線保持部62に対して一体形成され、並列状態で保持された端子54の先端部を囲む長円筒状の部分である。   The terminal surrounding portion 64 is a long cylindrical portion that is integrally formed with the electric wire holding portion 62 and surrounds the distal end portion of the terminal 54 held in parallel.

端子囲部64は、その軸方向の両端部で開口している。そして、コネクタ60の端子囲部64の一端部が相手側接続部材70側の接続口70hに嵌め込まれると共に、重ね合された接続部26A、26Bが、端子囲部64の一方側の開口を通じて、接続口70h内にある電線用端子72の先端部に重ね合される。この状態で、端子囲部64の他方側開口を利用して、端子54の先端部の孔に通されたネジSが、電線用端子72にネジ締めされる。この後、端子囲部64の他方側開口が別途蓋部材によって塞がれる。   The terminal surrounding portion 64 is open at both ends in the axial direction. Then, one end of the terminal enclosure 64 of the connector 60 is fitted into the connection port 70h on the counterpart connection member 70 side, and the overlapped connection sections 26A and 26B pass through the opening on one side of the terminal enclosure 64, It overlaps with the front-end | tip part of the terminal 72 for electric wires in the connection port 70h. In this state, the screw S passed through the hole at the tip of the terminal 54 is screwed to the wire terminal 72 using the other side opening of the terminal surrounding portion 64. Thereafter, the other side opening of the terminal surrounding portion 64 is separately closed by a lid member.

上記第1導電部材22Aと第2導電部材22Bとは、それぞれの凹部を対向させるようにして組合わされる。これにより、第1導電部材22Aと第2導電部材22Bとは、扁平な角筒状をなす。   The first conductive member 22A and the second conductive member 22B are combined so that the respective concave portions are opposed to each other. Accordingly, the first conductive member 22A and the second conductive member 22B form a flat rectangular tube shape.

この状態で、被覆電線52の延在方向中間部は、扁平な角筒状をなす面状導電部24A、24Bの間の空間に収容される。これにより、被覆電線52の延在方向中間部が、面状導電部24A、24Bによって囲まれる。   In this state, the intermediate portion in the extending direction of the covered electric wire 52 is accommodated in a space between the planar conductive portions 24A and 24B having a flat rectangular tube shape. Thereby, the extending direction intermediate part of the covered electric wire 52 is surrounded by the planar conductive parts 24A and 24B.

また、複数の被覆電線52の両端部の2つのコネクタ60のそれぞれの電線保持部62の一部が、扁平な角筒状をなすように組合わされた形状維持部28A、28B内に収容される。好ましくは、形状維持部28A、28Bは、電線保持部62の一部を挟込むように保持する。これにより、コネクタ付電線50に対して第1導電部材22Aと第2導電部材22Bとが取付けられる。   Moreover, a part of each electric wire holding | maintenance part 62 of the two connectors 60 of the both ends of the some covered electric wire 52 is accommodated in the shape maintenance parts 28A and 28B combined so that flat rectangular tube shape may be made. . Preferably, the shape maintaining portions 28A and 28B hold the electric wire holding portion 62 so as to sandwich a part thereof. Thus, the first conductive member 22A and the second conductive member 22B are attached to the connector-attached electric wire 50.

また、上記のように第1導電部材22Aと第2導電部材22Bとが組合わされた状態で、それぞれの接続部26A、26Bが重ね合される。そして、重ね合された接続部26A、26Bの孔26Ah、26BhにネジSが挿通され、当該ネジSが相手側接続部材70に締結される。これにより、本第1導電部材22Aと第2導電部材22Bとが、コネクタ付電線50と共に、相手側接続部材70に電気的及び機械的に接続される。なお、相手側接続部材70は、例えば、上記電線用端子72が組込まれた金属製の筐体である。これにより、第1導電部材22Aと第2導電部材22Bとが相手側接続部材70を通じて接地され、もって、電磁シールドとして機能することができる。また、第1導電部材22Aと第2導電部材22Bのそれぞれの両端側で上記接続が行われることで、2つの相手側接続部材70同士を電気的に接続することができる。   Further, in the state where the first conductive member 22A and the second conductive member 22B are combined as described above, the respective connection portions 26A and 26B are overlapped. Then, the screw S is inserted into the holes 26 </ b> Ah and 26 </ b> Bh of the overlapped connection portions 26 </ b> A and 26 </ b> B, and the screw S is fastened to the mating connection member 70. Thus, the first conductive member 22A and the second conductive member 22B are electrically and mechanically connected to the mating connection member 70 together with the connector-attached electric wire 50. In addition, the other party connection member 70 is a metal housing | casing in which the said terminal 72 for electric wires was integrated, for example. Accordingly, the first conductive member 22A and the second conductive member 22B are grounded through the mating connection member 70, and can function as an electromagnetic shield. Moreover, the said other connection member 70 can be electrically connected by the said connection being performed by each both-ends side of 22 A of 1st conductive members, and the 2nd conductive member 22B.

<導電部材の製造方法について>
上記第1導電部材22Aの製造方法例について説明する。なお、第2導電部材22Bについては、第1導電部材22Aと同様の製造方法によって製造することができる。
<About manufacturing method of conductive member>
A method for manufacturing the first conductive member 22A will be described. The second conductive member 22B can be manufactured by the same manufacturing method as the first conductive member 22A.

まず、図6に示すように、金属板30を準備する。金属板30は、方形状に形成されている。   First, as shown in FIG. 6, a metal plate 30 is prepared. The metal plate 30 is formed in a square shape.

そして、図7に示すように、金属板30のうち対向する2つの辺部分を残して、その中間領域にその厚み方向に沿った圧力を加えて延す。この際、金属板30の中間領域を一対の加圧ローラ38によって挟むことが好ましい。一対の加圧ローラ38の軸方向は、金属板30の上記対向する2つの辺部分に対して平行姿勢であり、一対の加圧ローラ38は、金属板30の中間領域を挟込んだ状態で、上記2つの辺部分の一方側から他方側に向けて移動する。これにより、金属板30は、主として上記2つの辺部分を結ぶ方向に沿って押し延され、当該方向において初期寸法よりも長く仕上げられる。   Then, as shown in FIG. 7, the two side portions facing each other out of the metal plate 30 are left, and a pressure along the thickness direction is applied to the intermediate region to extend. At this time, the intermediate region of the metal plate 30 is preferably sandwiched between the pair of pressure rollers 38. The axial direction of the pair of pressure rollers 38 is parallel to the two opposing side portions of the metal plate 30, and the pair of pressure rollers 38 is in a state of sandwiching the intermediate region of the metal plate 30. , And moves from one side of the two side portions toward the other side. Thereby, the metal plate 30 is mainly extended along the direction which connects the said 2 side part, and is finished longer than an initial dimension in the said direction.

すると、図8に示すように、対向する2つの辺部分30Baが初期の厚み寸法に維持されると共に、その中間領域30Bbが薄く圧延された金属板30Bが得られる。   Then, as shown in FIG. 8, a metal plate 30 </ b> B is obtained in which the two opposing side portions 30 </ b> Ba are maintained at the initial thickness dimension and the intermediate region 30 </ b> Bb is rolled thin.

なお、金属板30の中間領域にその厚み方向に沿った圧力を加えて薄くする加工は、上記のように一対の加圧ローラ38によるものの他、プレス加工により行われてもよいし、切削加工等により行われてもよい。   In addition, the process which applies the pressure along the thickness direction to the intermediate | middle area | region of the metal plate 30 and makes it thin may be performed by press work other than by the pair of pressure rollers 38 as described above, or cutting work. Etc. may be performed.

もっとも、上記のように一対の加圧ローラ38を用いて金属板30の中間領域を押し延すことによって、金属板30の無駄を無くして有効利用できる。   However, by using the pair of pressure rollers 38 as described above and extending the intermediate region of the metal plate 30, the metal plate 30 can be effectively used without being wasted.

なお、上記加工後、金属板30Bの外縁形状を整えるため、プレス加工等による周囲の切除加工等が行われてもよい。   In addition, after the said process, in order to arrange the outer edge shape of the metal plate 30B, the surrounding excision process etc. by press work etc. may be performed.

この後、図9に示すように、金属板30Bの辺部分30Baを、プレス型40に挟込んで、接続部26A、26B及び形状維持部28A、28Bを形成する。このプレス型40は、下型42及び上型46を備える。下型42は、接続部26A、26B及び形状維持部28A、28Bの外側部分を形作るための凹状の加工面43を有している。上型46は、接続部26A、26B及び形状維持部28A、28Bの内側部分を形作るための凸状の加工面47を有している。そして、上記辺部分30Baを、加工面43、47の間に挟み込むことで、上記形状維持部28A、28B及び接続部26A、26Bがプレス成形される。   Thereafter, as shown in FIG. 9, the side portions 30Ba of the metal plate 30B are sandwiched between the press dies 40 to form the connection portions 26A and 26B and the shape maintaining portions 28A and 28B. The press die 40 includes a lower die 42 and an upper die 46. The lower mold 42 has a concave processed surface 43 for forming the outer portions of the connecting portions 26A and 26B and the shape maintaining portions 28A and 28B. The upper mold 46 has a convex processed surface 47 for forming the inner portions of the connecting portions 26A and 26B and the shape maintaining portions 28A and 28B. The shape maintaining portions 28A and 28B and the connecting portions 26A and 26B are press-molded by sandwiching the side portion 30Ba between the processed surfaces 43 and 47.

また、上記下型42及び上型46の一方(ここでは上型46)に、孔26Ah、26Bhを形成するための円柱状の加工突部48が形成されており、他方(ここでは下型42)に上記加工突部48を挿入可能な孔44が形成されている。そして、上記辺部分30Baを、加工面43、47の間に挟み込む際、加工突部48が接続部26A、26Bを形成する部分に当接し、この部分に剪断等によって孔26Ah、26Bhを形成できるようになっている。これにより、形状維持部28A等を形成するためのプレス加工と孔開け加工とを同時に実施でき、製造コスト削減が可能となる。   Further, one of the lower mold 42 and the upper mold 46 (here, the upper mold 46) is provided with a cylindrical processing protrusion 48 for forming the holes 26Ah and 26Bh, and the other (here, the lower mold 42). ) Is formed with a hole 44 into which the machining protrusion 48 can be inserted. When the side portion 30Ba is sandwiched between the processing surfaces 43 and 47, the processing projection 48 comes into contact with a portion where the connection portions 26A and 26B are formed, and holes 26Ah and 26Bh can be formed in this portion by shearing or the like. It is like that. Thereby, it is possible to simultaneously perform the pressing process and the drilling process for forming the shape maintaining portion 28A and the like, and the manufacturing cost can be reduced.

図9に示す加工が、一対の辺部分30Baそれぞれに対して行われる。これにより、第1導電部材22Aが製造される。   The processing shown in FIG. 9 is performed on each of the pair of side portions 30Ba. Thereby, the first conductive member 22A is manufactured.

なお、第1導電部材22Aと第2導電部材22Bとが曲げ可能な薄さの連結部を介して繋がった状態で、一体形成されていてもよい。   Note that the first conductive member 22A and the second conductive member 22B may be integrally formed in a state where the first conductive member 22A and the second conductive member 22B are connected via a thin connecting portion that can be bent.

<効果等>
以上のように構成された第1導電部材22A及び第2導電部材22Bによると、面状導電部24Aは曲げ可能であるため、面状導電部24Aを曲った経路に沿って容易に配設することができる。例えば、第1導電部材22A及び第2導電部材22Bの一端部に接続される相手側接続部材70と、その他端部に接続される相手側接続部材70とが対向する位置関係になく、左右又は上下に位置ずれして設けられているような場合、或は、それらの間で被覆電線52が曲って配設されるような場合において、面状導電部24A、24Bを曲げつつ、第1導電部材22A及び第2導電部材22Bの両端部の接続部26A、26Bをそれぞれ相手側接続部材70に電気的及び機械的に接続することができる。また、面状導電部24A、24Bと接続部26A、26Bとが同じ金属材料によって形成されているため、異種金属接触による腐食も生じ難い。
<Effects>
According to the first conductive member 22A and the second conductive member 22B configured as described above, since the planar conductive portion 24A can be bent, the planar conductive portion 24A is easily disposed along a curved path. be able to. For example, the mating connection member 70 connected to one end of the first conductive member 22A and the second conductive member 22B and the mating connection member 70 connected to the other end are not in a positional relationship facing each other. In the case where the upper and lower positions are shifted, or in the case where the covered electric wire 52 is bent between them, the first conductive member is bent while bending the planar conductive portions 24A and 24B. The connection portions 26A and 26B at both ends of the member 22A and the second conductive member 22B can be electrically and mechanically connected to the mating connection member 70, respectively. In addition, since the planar conductive portions 24A and 24B and the connection portions 26A and 26B are formed of the same metal material, corrosion due to contact with different metals hardly occurs.

また、接続部26A、26Bは、金属板30の外周部の少なくとも一部に形成され、面状導電部24A、24Bの厚み寸法よりも大きい厚み寸法を有するため、面状導電部24A、24Bよりも高強度である。このため、接続部26A、26Bを、相手側接続部材70への電気的及び機械的な接続に適した構成とすることができる。   Further, since the connecting portions 26A and 26B are formed on at least a part of the outer peripheral portion of the metal plate 30 and have a thickness dimension larger than the thickness dimension of the planar conductive portions 24A and 24B, the connecting portions 26A and 26B are more than the planar conductive portions 24A and 24B. Is also high strength. For this reason, the connection portions 26 </ b> A and 26 </ b> B can be configured to be suitable for electrical and mechanical connection to the mating connection member 70.

また、面状導電部24A、24B及び接続部26A、26Bは、元々1つの金属板によって形成されているため、第1導電部材22A及び第2導電部材22Bそれぞれの構成部品点数の削減を図ることが可能となる。また、面状導電部24A、24Bと、接続部26A、26Bとは、金属板によって一体形成されているため、低抵抗化でき、それらの間での電気的な接続信頼性向上を図ることもできる。   Further, since the planar conductive portions 24A and 24B and the connection portions 26A and 26B are originally formed of one metal plate, the number of component parts of each of the first conductive member 22A and the second conductive member 22B is reduced. Is possible. Further, since the planar conductive portions 24A and 24B and the connecting portions 26A and 26B are integrally formed of a metal plate, the resistance can be reduced, and the electrical connection reliability between them can be improved. it can.

また、金属板30の外周部の少なくとも一部に、接続部26A、26Bと繋がった状態で形成される形状維持部28A、28Bをさらに備えるため、接続部26A、26Bを相手側接続部材に接続すると、形状維持部28A、28Bを一定位置に支持することができる。この形状維持部28A、28Bによって、面状導電部24A、24Bの一部を一定位置に支持することができる。また、ここでは、形状維持部28A、28Bによって、コネクタ付電線50のコネクタ60を支持しているため、当該コネクタ60を一定位置に支持することも可能となる。   Further, at least part of the outer peripheral portion of the metal plate 30 is further provided with shape maintaining portions 28A and 28B formed in a state of being connected to the connection portions 26A and 26B, so that the connection portions 26A and 26B are connected to the counterpart connection member. Then, the shape maintaining portions 28A and 28B can be supported at a fixed position. A part of the planar conductive portions 24A and 24B can be supported at a fixed position by the shape maintaining portions 28A and 28B. Moreover, since the connector 60 of the electric wire 50 with a connector is supported by the shape maintaining portions 28A and 28B here, the connector 60 can be supported at a fixed position.

また、面状導電部24A、24Bは、金属板30を薄く加工したものであるため、第1導電部材22A、第2導電部材22Bがばらばらな状態になり難いという利点もある。   Further, since the planar conductive portions 24A and 24B are formed by thinly processing the metal plate 30, there is an advantage that the first conductive member 22A and the second conductive member 22B are not easily separated.

また、接続部26A、26Bに孔26Ah、26Bhが形成されているため、その孔26Ah、26Bhを利用して、接続部26A、26Bを相手側接続部材70に容易に電気的及び機械的に接続できる。例えば、ネジ止固定等が可能になり、容易かつ確実な接続が可能となる。   Further, since the holes 26Ah and 26Bh are formed in the connection portions 26A and 26B, the connection portions 26A and 26B can be easily and electrically connected to the mating connection member 70 using the holes 26Ah and 26Bh. it can. For example, fixing with screws can be performed, and easy and reliable connection is possible.

また、接続部26A、26Bは、相手側接続部材70に機械的に接続された状態で、面状導電部24A、24Bが被覆電線52の外周を覆っている。このため、面状導電部24A、24Bによって、被覆電線52に対する電磁シールドが可能となる。   In addition, the connection portions 26 </ b> A and 26 </ b> B are mechanically connected to the mating connection member 70, and the planar conductive portions 24 </ b> A and 24 </ b> B cover the outer periphery of the covered electric wire 52. For this reason, electromagnetic shielding with respect to the covered electric wire 52 is attained by the planar conductive portions 24A and 24B.

<実施形態を前提とする変形例について>
上記実施形態を前提とする各種変形例について説明する。
<Modifications based on the embodiment>
Various modifications based on the above embodiment will be described.

図10に示す第1変形例に係る第1導電部材122A及び第2導電部材122Bでは、面状導電部24A、24Bに対応する面状導電部124A、124Bのそれぞれに孔125A、125Bが形成されている。   In the first conductive member 122A and the second conductive member 122B according to the first modification shown in FIG. 10, holes 125A and 125B are formed in the planar conductive portions 124A and 124B corresponding to the planar conductive portions 24A and 24B, respectively. ing.

ここでは、孔125A、125Bは、それぞれ菱形に形成されている。菱形をなす孔125A、125Bの対向する一組の頂点は、面状導電部124A、124Bの両端側の接続部26A、26Bを結ぶ方向に沿って配設され、他の一組の頂点は、面状導電部124A、124Bの両端側の接続部26A、26Bを結ぶ方向に対して直交する方向に沿って配設されている。   Here, the holes 125A and 125B are each formed in a diamond shape. The pair of opposing vertices of the rhomboid holes 125A and 125B are arranged along the direction connecting the connecting portions 26A and 26B on both ends of the planar conductive portions 124A and 124B, and the other set of vertices are The planar conductive portions 124A and 124B are disposed along a direction orthogonal to the direction connecting the connecting portions 26A and 26B on both ends.

また、ここでは、面状導電部124A、124Bのそれぞれに孔125A、125Bが複数形成されている。各孔125A、125Bは、面状導電部124A、124Bの両端側の接続部26A、26Bを結ぶ方向、及び、これに直交する方向のそれぞれにおいて、均等間隔で形成されている。   Here, a plurality of holes 125A and 125B are formed in the planar conductive portions 124A and 124B, respectively. The holes 125A and 125B are formed at equal intervals in the direction connecting the connecting portions 26A and 26B on both ends of the planar conductive portions 124A and 124B and in the direction orthogonal thereto.

上記のような孔125A、125Bは、上記金属板30、30Bに対して打抜き加工等することによって形成することができる。   The holes 125A and 125B as described above can be formed by punching the metal plates 30 and 30B.

この第1変形例によると、面状導電部124A、124Bに孔125A、125Bが形成されているため、当該面状導電部124A、124Bが曲り易くなり、従って、曲った経路に沿って容易に配設することができるという利点がある。特に、孔125A、125Bが複数形成されているため、面状導電部124A、124Bは、より容易に曲ることができる。   According to the first modification, since the holes 125A and 125B are formed in the planar conductive portions 124A and 124B, the planar conductive portions 124A and 124B are easily bent, and therefore easily along the curved path. There is an advantage that it can be arranged. In particular, since a plurality of holes 125A and 125B are formed, the planar conductive portions 124A and 124B can be bent more easily.

また、孔125A、125Bが菱形に形成されているため、当該孔125A、125Bを、面状導電部124A、124Bの両端側の接続部26A、26Bを結ぶ方向に沿って延すように変形させることによって、面状導電部124A、124Bを容易に伸縮変形させることができるという利点がある。   Further, since the holes 125A and 125B are formed in a diamond shape, the holes 125A and 125B are deformed so as to extend along the direction connecting the connecting portions 26A and 26B on both ends of the planar conductive portions 124A and 124B. Accordingly, there is an advantage that the planar conductive portions 124A and 124B can be easily stretched and deformed.

もっとも、面状導電部には、複数の孔が形成されている必要はない。面状導電部に少なくとも1つの孔が形成されていれば、面状導電部は変形容易となる。また、孔の形状は、菱形に限られず、円形状、長円形状、多角形状等、或はスリット形状であってもよい。   However, a plurality of holes need not be formed in the planar conductive portion. If at least one hole is formed in the planar conductive portion, the planar conductive portion can be easily deformed. Further, the shape of the hole is not limited to a rhombus, and may be a circular shape, an oval shape, a polygonal shape, or a slit shape.

図11に示す第2変形例に係る第1導電部材222A及び第2導電部材222Bでは、上記実施形態において形状維持部28A、28Bが省略されており、面状導電部24A、24Bに対応する面状導電部224A、224Bに対して接続部26A、26Bだけが繋がっている。この場合でも、接続部26A、26Bを相手側接続部材に電気的及び機械的に接続することによって、面状導電部224A、224Bを相手側接続部材に電気的に接続することができる。なお、ここでは、面状導電部224A、224Bは、実施形態で説明した形状維持部28A、28Bによって所定形状に維持されていないため、接続部26A、26Bを相手側接続部材に電気的及び機械的に接続する前の状態では、平面状に延在している。接続部26A、26Bを相手側接続部材に電気的及び機械的に接続する際に、面状導電部224A、224Bは、被覆電線を囲うことが可能な形状に適宜変形されればよい。   In the first conductive member 222A and the second conductive member 222B according to the second modification shown in FIG. 11, the shape maintaining portions 28A and 28B are omitted in the above embodiment, and the surfaces corresponding to the planar conductive portions 24A and 24B. Only the connecting portions 26A and 26B are connected to the conductive portions 224A and 224B. Even in this case, the planar conductive portions 224A and 224B can be electrically connected to the counterpart connection member by electrically and mechanically connecting the connection portions 26A and 26B to the counterpart connection member. Here, since the planar conductive portions 224A and 224B are not maintained in a predetermined shape by the shape maintaining portions 28A and 28B described in the embodiment, the connection portions 26A and 26B are electrically and mechanically connected to the mating connection member. In a state before the connection, it extends in a planar shape. When electrically connecting the connecting portions 26A and 26B to the counterpart connecting member electrically and mechanically, the planar conductive portions 224A and 224B may be appropriately modified into a shape that can surround the covered electric wire.

図12に示す第3変形例に係る第1導電部材322A(第2導電部材322B)は、上記第2変形例を前提として、面状導電部224A、224Bに対応する面状導電部324A、324Bが、面状導電部324A、324Bの両端の接続部26A、26Bを結ぶ方向に対して直交する複数の平行線に沿った線で折曲げられることで、蛇腹状に折られている。このため、面状導電部324A、324Bは、折られた部分の角度を変更するようにして、容易に曲ること、及び、伸縮することができる。これにより、配設対象となる経路に沿って、面状導電部324A、324Bをより容易に曲げることができる。   The first conductive member 322A (second conductive member 322B) according to the third modification shown in FIG. 12 is based on the second modification, and the planar conductive portions 324A and 324B corresponding to the planar conductive portions 224A and 224B. Is folded in a bellows shape by being bent along a plurality of parallel lines perpendicular to the direction connecting the connecting portions 26A and 26B at both ends of the planar conductive portions 324A and 324B. Therefore, the planar conductive portions 324A and 324B can be easily bent and expanded and contracted so as to change the angle of the folded portion. Thereby, the planar conductive portions 324A and 324B can be more easily bent along the path to be arranged.

図13に示す第4変形例に係る第1導電部材422A及び第2導電部材422Bでは、面状導電部24A、24Bに対応する面状導電部424A、424Bが、その両端の接続部26A、26B及び形状維持部28A、28Bに対して斜め方向に傾斜(図13ではその内側から観察して下側に向けて左側傾斜)する形状に形成されている。   In the first conductive member 422A and the second conductive member 422B according to the fourth modification shown in FIG. 13, the planar conductive portions 424A and 424B corresponding to the planar conductive portions 24A and 24B are connected to the connecting portions 26A and 26B at both ends. In addition, the shape maintaining portions 28A and 28B are formed in a shape that is inclined in an oblique direction (in FIG. 13, it is observed from the inner side and is inclined leftward toward the lower side).

このため、第1導電部材422A及び第2導電部材422Bとを、扁平な角筒状をなすように組合わせると、面状導電部424A及び面状導電部424Bによって構成される扁平な角筒状部分が、その一端側開口部及び他端側開口部に対して傾く方向に延在する。   Therefore, when the first conductive member 422A and the second conductive member 422B are combined so as to form a flat rectangular tube shape, a flat rectangular tube shape constituted by the planar conductive portion 424A and the planar conductive portion 424B. The portion extends in a direction inclined with respect to the one end side opening and the other end side opening.

本変形例は、接続対象となる相手側接続部材が互いに対向する位置から横方向にずれて配設されるような場合に有効である。   This modification is effective in the case where the counterpart connection members to be connected are arranged so as to be shifted laterally from positions facing each other.

例えば、上記実施形態のように、第1導電部材22A及び第2導電部材22Bとが扁平な角筒状をなすように組合わされると、その第1導電部材22A及び第2導電部材22Bは、厚み方向には比較的容易に曲ることができるが、幅広となる幅方向には相対的に曲り難くなる。そこで、本変形例のように、第1導電部材422A及び第2導電部材422Bとが扁平な角筒状をなすように組合わされる場合において、面状導電部424A、424Bを、その両端部を結ぶ方向においてその幅方向に傾くように形成しておくことで、接続対象となる相手側接続部材がその第1導電部材422A及び第2導電部材422Bの幅方向に位置ずれした位置関係にある場合でも、第1導電部材422A及び第2導電部材422Bの両端部を容易に相手側接続部材に接続して配設することが容易となる。   For example, as in the above embodiment, when the first conductive member 22A and the second conductive member 22B are combined so as to form a flat rectangular tube, the first conductive member 22A and the second conductive member 22B are Although it can bend comparatively easily in the thickness direction, it is relatively difficult to bend in the wide width direction. Therefore, when the first conductive member 422A and the second conductive member 422B are combined so as to form a flat rectangular tube as in this modification, the planar conductive portions 424A and 424B are attached to both ends. In the case where the mating connection member to be connected is in a positional relationship shifted in the width direction of the first conductive member 422A and the second conductive member 422B by forming it so as to be inclined in the width direction in the connecting direction. However, it becomes easy to easily connect both ends of the first conductive member 422A and the second conductive member 422B to the mating connection member.
