特開２０１１−２１０４８１号公報JP, 2011-210481, A

しかしながら、特許文献１の構造では、接続配線を接続対象であるバッテリーや他の装置に対して着脱する際に、接続配線の一方の端部がバッテリーの電極端子に触れ、接続配線の他方の端部が意図しない導体部分（例えば目的としない別の電極端子や、導体からなるバッテリーの筐体部位など）に触れると、バッテリーが短絡してしまう、という問題がある。
また、特許文献１の構造では、接続配線をバッテリーや他の装置等の接続対象から取り外した状態において、接続配線とナットとを別個に管理する必要がある。すなわち、接続対象同士を電気接続するための部品の管理が面倒である、という問題もある。 However, in the structure of Patent Document 1, when the connection wiring is attached to or detached from the battery or other device to be connected, one end of the connection wiring touches the electrode terminal of the battery, and the other end of the connection wiring There is a problem that the battery may be short-circuited when the conductor touches an unintended conductor part (for example, another unintended electrode terminal, a housing part of the battery made of a conductor, etc.).
Further, in the structure of Patent Document 1, it is necessary to manage the connection wiring and the nut separately in a state where the connection wiring is removed from the connection target such as a battery or another device. That is, there is also a problem that management of parts for electrically connecting connection targets is troublesome.

本発明は、上述した事情に鑑みたものであって、接続配線を着脱する際にバッテリーの短絡を抑制できると共に、バッテリーや他の装置等の接続対象同士を電気接続するための部品を容易に管理できる配線ユニットを提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and can prevent a short circuit of a battery when attaching and detaching a connection wiring, and easily facilitates components for electrically connecting connection objects such as a battery and other devices. The purpose is to provide a wiring unit that can be managed.

この課題を解決するために、本発明の配線ユニットは、両端に板状の配線端子部を有する接続配線と、一方向に開口する箱状に形成され、前記配線端子部を収容する電気絶縁性の保護カバーと、前記保護カバーに収容され、前記配線端子部を接続対象の電極端子部にネジ止め固定するためのネジと、を備え、前記配線端子部及び前記ネジが、前記保護カバー内に保持され、前記配線端子部が、前記保護カバーの周壁部に形成された端子挿通孔に挿通されて、前記保護カバー内に配され、前記ネジが、前記配線端子部のネジ挿通孔に挿通され、前記端子挿通孔が、前記ネジ挿通孔に挿通された前記ネジを挿通不能とする形状に形成され、前記ネジ挿通孔の径寸法が、前記ネジの頭部の外径寸法よりも小さく設定され、前記ネジの頭部は、前記ネジの軸部が前記ネジ挿通孔に挿通された状態で、前記配線端子部と前記周壁部の軸方向の一端を閉塞する前記保護カバーの端壁部との間に位置し、前記保護カバーの端壁部に、前記ネジの頭部を前記保護カバーの外側から操作するための操作用孔が形成され、前記操作用孔の径寸法が、前記ネジの頭部の径寸法よりも小さく設定され、前記ネジの軸部は、前記ネジの頭部が前記保護カバーの端壁部に当接した状態で前記ネジ挿通孔に挿通した状態に保持され、前記ネジの頭部が前記端壁部に対向する前記配線端子部の一方の主面に当接した状態で、前記配線端子部の他方の主面から突出する前記ネジの軸部の長さが、前記配線端子部から前記保護カバーの開口端までの距離よりも短いことを特徴とする。 In order to solve this problem, the wiring unit of the present invention is formed into a connection wiring having a plate-like wiring terminal portion at both ends and a box shape opened in one direction, and an electrical insulating property that accommodates the wiring terminal portion. A protective cover, and a screw accommodated in the protective cover for screwing and fixing the wiring terminal portion to an electrode terminal portion to be connected, the wiring terminal portion and the screw being in the protective cover Held , the wiring terminal portion is inserted into the terminal insertion hole formed in the peripheral wall portion of the protective cover and disposed in the protective cover, and the screw is inserted into the screw insertion hole of the wiring terminal portion The terminal insertion hole is formed in a shape that does not allow insertion of the screw inserted into the screw insertion hole, and the diameter of the screw insertion hole is set smaller than the outer diameter of the head of the screw. , The head of the screw is Is located between the wiring terminal and an end wall of the protective cover that closes one end of the peripheral wall in the axial direction, with the shaft of the screw inserted through the screw insertion hole, An operation hole for operating the head of the screw from the outside of the protective cover is formed in the wall portion, and the diameter of the operation hole is set smaller than the diameter of the head of the screw, The shank of the screw is held in a state in which the head of the screw is in contact with the end wall of the protective cover and is inserted through the screw insertion hole, and the head of the screw faces the end wall The length of the axial portion of the screw projecting from the other main surface of the wiring terminal portion in a state of being in contact with one main surface of the wiring terminal portion is the opening end of the protective cover from the wiring terminal portion It is characterized by being shorter than the distance to.

本発明によれば、配線端子部及びネジが保護カバー内に保持されるため、接続配線の一方の配線端子部が接続対象の一種であるバッテリーの電極端子部に触れている状態で、他方の配線端子部が意図しない導体部分に触れてしまうことを抑制できる。すなわち、接続配線をバッテリーの電極端子部に着脱する際に、バッテリーが短絡することを抑制できる。
また、配線端子部及びネジの両方が保護カバー内に保持されるため、接続配線を接続対象の電極端子部から取り外した状態であっても、ネジと接続配線とを別個に管理する必要がない。すなわち、接続対象同士を電気接続するための部品を容易に管理することができる。 According to the present invention, since the wiring terminal portion and the screw are held in the protective cover, one of the wiring terminal portions of the connection wiring is in contact with the electrode terminal portion of the battery which is a kind of connection target. It can suppress that a wiring terminal part touches an unintended conductor part. That is, when attaching and detaching connection wiring to the electrode terminal part of a battery, it can suppress that a battery short-circuits.
Further, since both the wiring terminal portion and the screw are held in the protective cover, it is not necessary to separately manage the screw and the connection wiring even in a state where the connection wiring is removed from the electrode terminal portion to be connected . That is, parts for electrically connecting connection targets can be easily managed.

〔第一実施形態〕
以下、図１〜４を参照して本発明の第一実施形態について説明する。
図１に示すように、本実施形態における配線ユニット１は、例えば正負一対の電極端子部１０２，１０２を有する二つのバッテリー（接続対象）１００同士を電気接続する。 First Embodiment
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the wiring unit 1 in the present embodiment electrically connects two batteries (connection target) 100 having, for example, a pair of positive and negative electrode terminal portions 102.

図１において、各バッテリー１００は、本体部１０１と、本体部１０１から突出する一対の電極端子部１０２，１０２と、を有する。電極端子部１０２が設けられる本体部１０１の設置面１０３は、例えば平坦に形成されてもよいが、本実施形態では段差を有して形成されている。   In FIG. 1, each battery 100 has a main body portion 101 and a pair of electrode terminal portions 102 and 102 protruding from the main body portion 101. The installation surface 103 of the main body portion 101 on which the electrode terminal portion 102 is provided may be formed flat, for example, but in the present embodiment, it is formed with a step.

図１，２に示すように、電極端子部１０２は、導電性を有する帯板からなる端子部本体１０４を備える。
端子部本体１０４には、後述する配線ユニット１の配線端子部５をネジ止めするためのネジ止め用孔１０５が形成されている。ネジ止め用孔１０５は、例えば後述するネジ４を螺着させるように形成されてもよいが、本実施形態のネジ止め用孔１０５は、ネジ４を単に挿通させるように形成されている。このため、本実施形態の電極端子部１０２は、端子部本体１０４に固定され、ネジ止め用孔１０５に挿通されたネジ４を螺着させるナット１０６を備える。 As shown to FIG.1, 2, the electrode terminal part 102 is equipped with the terminal part main body 104 which consists of a strip which has electroconductivity.
In the terminal portion main body 104, a screwing hole 105 for screwing a wiring terminal portion 5 of the wiring unit 1 described later is formed. The screwing hole 105 may be formed, for example, to screw a screw 4 described later, but the screwing hole 105 of the present embodiment is formed to simply insert the screw 4. For this reason, the electrode terminal portion 102 of the present embodiment is provided with a nut 106 which is fixed to the terminal portion main body 104 and which is screwed with the screw 4 inserted into the screw hole 105.

本実施形態において、電極端子部１０２は、設置面１０３のうち低く位置する平坦な下段面１０７から突出している。また、電極端子部１０２は、その突出方向の中途部において折り曲げられ、断面Ｌ字状に形成されている。そして、電極端子部１０２の突出方向先端部は、下段面１０７よりも一段高く位置する平坦な上段面１０８の上方まで延びている。すなわち、本実施形態の電極端子部１０２は、設置面１０３のうち段差部分を含む領域に設けられている。
前述したネジ止め用孔１０５は、電極端子部１０２の突出方向先端部に形成されている。電極端子部１０２の突出方向先端部は、例えば下段面１０７や上段面１０８に平行するように延びてもよいが、これに限ることはない。 In the present embodiment, the electrode terminal portion 102 protrudes from a flat lower surface 107 located lower than the installation surface 103. Further, the electrode terminal portion 102 is bent at a middle portion in the protruding direction, and is formed in an L-shaped cross section. The tip end of the electrode terminal portion 102 in the projecting direction extends above the flat upper surface 108 located one step higher than the lower surface 107. That is, the electrode terminal portion 102 of the present embodiment is provided in the region including the step portion in the installation surface 103.
The screwing hole 105 described above is formed at the tip of the electrode terminal portion 102 in the protruding direction. For example, the tip end of the electrode terminal portion 102 in the projecting direction may extend parallel to the lower surface 107 and the upper surface 108, but the present invention is not limited to this.

本実施形態に係る配線ユニット１は、接続配線２と、保護カバー３と、ネジ４と、を備える。
接続配線２は、二つのバッテリー１００の電極端子部１０２を電気接続するため、導電性を有する。接続配線２は、その長手方向の両端に板状の配線端子部５を有する。各配線端子部５は、ネジ４によってバッテリー１００の電極端子部１０２にネジ止め固定される部位である。各配線端子部５には、ネジ４を挿通させるネジ挿通孔１１が形成されている。ネジ挿通孔１１は配線端子部５の板厚方向に貫通して形成されている。
接続配線２のうち配線端子部５を除く部位は、電気絶縁性を有する絶縁被覆部６によって被覆されている。接続配線２のうち配線端子部５を除く部位は、例えば線材によって構成されてもよいが、本実施形態では、接続配線２全体が帯板状に形成されている。 The wiring unit 1 according to the present embodiment includes a connection wiring 2, a protective cover 3, and a screw 4.
The connection wiring 2 is electrically conductive in order to electrically connect the electrode terminal portions 102 of the two batteries 100. The connection wiring 2 has plate-like wiring terminal portions 5 at both ends in the longitudinal direction. Each wiring terminal portion 5 is a portion screwed and fixed to the electrode terminal portion 102 of the battery 100 by the screw 4. Each wiring terminal portion 5 is formed with a screw insertion hole 11 through which the screw 4 is inserted. The screw insertion hole 11 is formed to penetrate in the thickness direction of the wiring terminal portion 5.
The portion of the connection wiring 2 excluding the wiring terminal portion 5 is covered with an insulating covering portion 6 having electrical insulation. Although the site | part except the wiring terminal part 5 may be comprised with a wire, for example among the connection wiring 2, in this embodiment, the connection wiring 2 whole is formed in band plate shape.

ネジ４は、配線端子部５をバッテリー１００の電極端子部１０２にネジ止め固定するためのものであり、軸部１８及び頭部１９を有する。ネジ４の軸部１８は、配線端子部５のネジ挿通孔１１に挿通された上で、バッテリー１００の電極端子部１０２に螺着される部位である。ネジ４の頭部１９の外径寸法は、頭部１９がネジ挿通孔１１を通らないように、ネジ挿通孔１１の径寸法よりも小さく設定される。
ネジ４の頭部１９の頂面は、例えば平坦面であってもよいが、本実施形態ではネジ４の上方に膨出する球面状に形成されている。ネジ４は、その頭部１９の頂面にドライバー等の工具で回すための溝や穴を形成したものであるとよい。ネジ４は、例えば電気絶縁性を有してもよいが、本実施形態では導電性を有する。 The screw 4 is for screwing and fixing the wiring terminal portion 5 to the electrode terminal portion 102 of the battery 100, and has a shaft portion 18 and a head portion 19. The shaft portion 18 of the screw 4 is a portion inserted into the screw insertion hole 11 of the wiring terminal portion 5 and then screwed to the electrode terminal portion 102 of the battery 100. The outer diameter of the head 19 of the screw 4 is set smaller than the diameter of the screw insertion hole 11 so that the head 19 does not pass through the screw insertion hole 11.
The top surface of the head 19 of the screw 4 may be, for example, a flat surface, but in the present embodiment, it is formed in a spherical shape that bulges above the screw 4. The screw 4 may have a groove or hole formed on the top surface of the head 19 for turning with a tool such as a screwdriver. The screw 4 may have, for example, electrical insulation, but in the present embodiment it has electrical conductivity.

保護カバー３は、電気絶縁性を有する。保護カバー３は、一方向（図２において下方向）に開口する箱状に形成され、配線端子部５及びネジ４を収容する。また、保護カバー３は、その内部に配線端子部５及びネジ４を保持する。以下、本実施形態の保護カバー３について、具体的に説明する。   The protective cover 3 has electrical insulation. The protective cover 3 is formed in a box shape that opens in one direction (downward direction in FIG. 2), and accommodates the wiring terminal portion 5 and the screw 4. In addition, the protective cover 3 holds the wiring terminal portion 5 and the screw 4 inside. Hereinafter, the protective cover 3 of the present embodiment will be specifically described.

保護カバー３は、筒状に形成される周壁部２１と、周壁部２１の軸方向の一端を閉塞する端壁部２２と、を備える。すなわち、保護カバー３は有底筒状に形成されている。
本実施形態の周壁部２１は、角筒状に形成されている。また、本実施形態の端壁部２２は、平板状に形成されている。 The protective cover 3 includes a peripheral wall portion 21 formed in a tubular shape, and an end wall portion 22 that closes one end of the peripheral wall portion 21 in the axial direction. That is, the protective cover 3 is formed in a bottomed cylindrical shape.
The peripheral wall portion 21 of the present embodiment is formed in a square tube shape. Moreover, the end wall part 22 of this embodiment is formed in flat form.

保護カバー３の周壁部２１には、保護カバー３の内外に貫通し、接続配線２の配線端子部５を挿通させる端子挿通孔２３が形成されている。端子挿通孔２３は、周壁部２１のうち、端壁部２２や保護カバー３の開口端２５に対して間隔をあけた位置に形成されている、すなわち、軸方向において周壁部２１の中途部に形成されている。   The peripheral wall portion 21 of the protective cover 3 is formed with a terminal insertion hole 23 which penetrates the inside and the outside of the protective cover 3 and through which the wiring terminal portion 5 of the connection wiring 2 is inserted. The terminal insertion hole 23 is formed in the circumferential wall 21 at a position spaced apart from the end wall 22 and the opening end 25 of the protective cover 3, that is, in the middle of the circumferential wall 21 in the axial direction. It is formed.

また、端子挿通孔２３は、配線端子部５のネジ挿通孔１１に挿通されたネジ４を挿通不能とする形状に形成されている。本実施形態において、端子挿通孔２３は、その貫通方向から見て、接続配線２の長手方向に直交する配線端子部５の断面形状に対応する形状に形成されている。より具体的には、端子挿通孔２３は、配線端子部５の断面形状に対して同等の大きさまたは若干大きい長孔形状に形成されている。このため、配線端子部５のネジ挿通孔１１に挿通されたネジ４は、端子挿通孔２３を通り抜けることができない。これにより、配線端子部５及びネジ４が、保護カバー３内に保持される。   Further, the terminal insertion hole 23 is formed in a shape that can not insert the screw 4 inserted into the screw insertion hole 11 of the wiring terminal portion 5. In the present embodiment, the terminal insertion hole 23 is formed in a shape corresponding to the cross-sectional shape of the wiring terminal portion 5 orthogonal to the longitudinal direction of the connection wiring 2 when viewed from the penetration direction. More specifically, the terminal insertion hole 23 is formed in an elongated hole shape having a size equal to or slightly larger than the cross-sectional shape of the wiring terminal portion 5. Therefore, the screw 4 inserted into the screw insertion hole 11 of the wiring terminal portion 5 can not pass through the terminal insertion hole 23. Thereby, the wiring terminal portion 5 and the screw 4 are held in the protective cover 3.

端子挿通孔２３には、例えば、接続配線２を被覆する絶縁被覆部６が挿入されてもよい。また、絶縁被覆部６で被覆された接続配線２の部位は、例えば端子挿通孔２３に嵌るように形成されてもよい。この場合には、接続配線２が保護カバー３に対して端子挿通孔２３の貫通方向に移動することを効果的に規制できる。   For example, an insulating covering portion 6 that covers the connection wiring 2 may be inserted into the terminal insertion hole 23. In addition, the portion of the connection wiring 2 covered by the insulating covering portion 6 may be formed to fit into the terminal insertion hole 23, for example. In this case, movement of the connection wiring 2 in the penetrating direction of the terminal insertion hole 23 with respect to the protective cover 3 can be effectively restricted.

ネジ４の頭部１９は、保護カバー３内においてネジ４の軸部１８がネジ挿通孔１１に挿通された状態で、配線端子部５と保護カバー３の端壁部２２との間に位置する。保護カバー３の端壁部２２には、端壁部２２の厚さ方向（周壁部２１の軸方向）に貫通し、ネジ４の頭部１９を保護カバー３の外側から操作するための操作用孔２４が形成されている。
操作用孔２４の径寸法は、ネジ４の頭部１９の径寸法よりも小さく設定されている。このため、ネジ４が操作用孔２４を通して保護カバー３の外側に抜け出ることはない。
また、ネジ４の軸部１８は、ネジ４の頭部１９が保護カバー３の端壁部２２に当接した状態でネジ挿通孔１１に挿通した状態に保持される。具体的には、配線端子部５と端壁部２２との間隔が、ネジ４の軸方向長さよりも短く設定されている。 The head 19 of the screw 4 is positioned between the wiring terminal 5 and the end wall 22 of the protective cover 3 in a state where the shaft 18 of the screw 4 is inserted into the screw insertion hole 11 in the protective cover 3. . The end wall portion 22 of the protective cover 3 penetrates in the thickness direction of the end wall portion 22 (axial direction of the peripheral wall portion 21), and is for operation for operating the head 19 of the screw 4 from the outside of the protective cover 3 Holes 24 are formed.
The diameter of the operation hole 24 is set smaller than the diameter of the head 19 of the screw 4. Therefore, the screw 4 does not come out of the protective cover 3 through the operation hole 24.
Further, the shaft portion 18 of the screw 4 is held in a state of being inserted into the screw insertion hole 11 in a state in which the head portion 19 of the screw 4 abuts on the end wall portion 22 of the protective cover 3. Specifically, the distance between the wiring terminal portion 5 and the end wall portion 22 is set shorter than the axial length of the screw 4.

本実施形態において、前述した操作用孔２４の径寸法は、ドライバー等の工具を挿通できる程度に大きく設定されている。
また、操作用孔２４の径寸法や操作用孔２４の貫通方向の寸法（端壁部２２の厚さ）は、ネジ４の頭部１９が端壁部２２に当接した状態でネジ４の頭部１９の一部が操作用孔２４に入り込んでも、ネジ４の頭部１９の一部が保護カバー３の外側に突出しないように設定されている。 In the present embodiment, the diameter of the operation hole 24 described above is set large enough to allow insertion of a tool such as a driver.
Further, the diameter of the operation hole 24 and the dimension in the penetration direction of the operation hole 24 (the thickness of the end wall portion 22) are set in the state where the head 19 of the screw 4 is in contact with the end wall portion 22. Even if a part of the head 19 enters the operation hole 24, a part of the head 19 of the screw 4 is set so as not to protrude to the outside of the protective cover 3.

また、本実施形態の配線ユニット１では、ネジ４の頭部１９が端壁部２２に対向する配線端子部５の一方の主面１２ａに当接した状態で、配線端子部５の他方の主面１２ｂから突出するネジ４の軸部１８の長さが、配線端子部５の他方の主面１２ｂから保護カバー３の開口端２５までの距離よりも短く設定されている。このため、ネジ４の軸部１８は、保護カバー３の開口端２５から外側に突出しない。   Further, in the wiring unit 1 of the present embodiment, the other main portion of the wiring terminal portion 5 is in a state in which the head portion 19 of the screw 4 is in contact with one main surface 12 a of the wiring terminal portion 5 facing the end wall portion 22. The length of the shaft portion 18 of the screw 4 protruding from the surface 12 b is set to be shorter than the distance from the other main surface 12 b of the wiring terminal portion 5 to the opening end 25 of the protective cover 3. Therefore, the shaft 18 of the screw 4 does not protrude outward from the open end 25 of the protective cover 3.

また、本実施形態の配線ユニット１では、前述した端子挿通孔２３が、周壁部２１の周方向に間隔をあけて複数配列されている。本実施形態において、端子挿通孔２３は、角筒状に形成された周壁部２１を構成する四つの平板部に、一つずつ形成されている。   Further, in the wiring unit 1 of the present embodiment, a plurality of the terminal insertion holes 23 described above are arranged at intervals in the circumferential direction of the peripheral wall portion 21. In the present embodiment, the terminal insertion holes 23 are formed one by one in four flat plate portions constituting the peripheral wall portion 21 formed in a square tube shape.

さらに、本実施形態の配線ユニット１では、保護カバー３の開口端２５が、バッテリー１００の設置面１０３に対応する形状に形成されている。本実施形態では、保護カバー３の開口端２５が、設置面１０３に対応する段差を有して形成されている。より具体的には、保護カバー３の開口端２５は、設置面１０３の下段面１０７に接触する第一部位２６と、第一部位２６よりも周壁部２１の軸方向に窪んで位置し、設置面１０３の上段面１０８に接触する第二部位２７と、を有する。   Furthermore, in the wiring unit 1 of the present embodiment, the opening end 25 of the protective cover 3 is formed in a shape corresponding to the installation surface 103 of the battery 100. In the present embodiment, the opening end 25 of the protective cover 3 is formed with a step corresponding to the installation surface 103. More specifically, the open end 25 of the protective cover 3 is located in the axial direction of the peripheral wall 21 with respect to the first portion 26 in contact with the lower surface 107 of the installation surface 103 and the first portion 26 And a second portion 27 in contact with the upper end surface 108 of the surface 103.

次に、上記構成の配線ユニット１をバッテリー１００の電極端子部１０２に対して着脱する方法について説明する。   Next, the method of attaching and detaching the wiring unit 1 of the said structure with respect to the electrode terminal part 102 of the battery 100 is demonstrated.

例えば、配線ユニット１をバッテリー１００の電極端子部１０２に取り付ける場合には、はじめに、図３に示すように、電極端子部１０２が保護カバー３の開口端２５から保護カバー３内に挿入されように、保護カバー３をバッテリー１００の設置面１０３に載置する。また、保護カバー３内に配された配線端子部５の他方の主面１２ｂが電極端子部１０２に対して面接触するように、配線端子部５を電極端子部１０２に対して重ねて配する。
ここで、配線端子部５は保護カバー３によって覆われているため、作業者は配線端子部５に触れることなく、配線端子部５を電極端子部１０２に対して重ねて配することができる。 For example, when the wiring unit 1 is attached to the electrode terminal portion 102 of the battery 100, first, as shown in FIG. 3, the electrode terminal portion 102 is inserted into the protective cover 3 from the opening end 25 of the protective cover 3. The protective cover 3 is placed on the mounting surface 103 of the battery 100. Further, the wiring terminal portion 5 is disposed so as to overlap with the electrode terminal portion 102 so that the other main surface 12 b of the wiring terminal portion 5 disposed in the protective cover 3 is in surface contact with the electrode terminal portion 102. .
Here, since the wiring terminal portion 5 is covered by the protective cover 3, the operator can arrange the wiring terminal portion 5 in an overlapping manner with the electrode terminal portion 102 without touching the wiring terminal portion 5.

上記のように保護カバー３及び配線端子部５を配した状態においては、保護カバー３内のネジ４が電極端子部１０２に螺着していない。このため、ネジ４は、保護カバー３内において配線端子部５の一方の主面１２ａから保護カバー３の端壁部２２に向かって突出するように配される。
ただし、端壁部２２に形成される操作用孔２４の径寸法はネジ４の頭部１９の径寸法よりも小さいため、ネジ４が操作用孔２４を通して保護カバー３の外側に抜け出ることはない。また、ネジ４の頭部１９が保護カバー３の外側に突出することもない。したがって、作業者がネジ４の頭部１９に触れることを抑制できる。 In the state in which the protective cover 3 and the wiring terminal portion 5 are arranged as described above, the screw 4 in the protective cover 3 is not screwed to the electrode terminal portion 102. For this reason, the screw 4 is disposed so as to project toward the end wall 22 of the protective cover 3 from the one main surface 12 a of the wiring terminal 5 in the protective cover 3.
However, since the diameter dimension of the operation hole 24 formed in the end wall portion 22 is smaller than the diameter dimension of the head 19 of the screw 4, the screw 4 does not come out of the protective cover 3 through the operation hole 24 . Also, the head 19 of the screw 4 does not protrude outside the protective cover 3. Therefore, the operator can be prevented from touching the head 19 of the screw 4.

上記のように保護カバー３及び配線端子部５を配した後には、図４に示すように、ネジ４を電極端子部１０２に螺着させることで、配線端子部５をバッテリー１００の電極端子部１０２にネジ止め固定する。これにより、配線ユニット１の取り付けが完了する。
ネジ４を電極端子部１０２に螺着させる際、作業者は、一方の手で保護カバー３または接続配線２のうち絶縁被覆部６によって被覆された部位を掴み、他方の手で掴んだドライバー等の工具を操作用孔２４から保護カバー３内に挿入し、工具によってネジ４を回せばよい。 After arranging the protective cover 3 and the wiring terminal portion 5 as described above, as shown in FIG. 4, the screw 4 is screwed to the electrode terminal portion 102 so that the wiring terminal portion 5 is the electrode terminal portion of the battery 100. Fix screw to 102. Thus, the mounting of the wiring unit 1 is completed.
When screwing the screw 4 to the electrode terminal portion 102, the operator grasps the portion of the protective cover 3 or the connection wiring 2 covered with the insulating coating portion 6 with one hand, and the driver etc. grasped with the other hand The tool is inserted into the protective cover 3 from the operation hole 24 and the screw 4 is turned by the tool.

配線ユニット１をバッテリー１００の電極端子部１０２から取り外す場合には、はじめに、作業者が、ネジ４を電極端子部１０２に螺着させる場合と同様にネジ４を回して、電極端子部１０２に対するネジ４の螺着を解除すればよい。その後、作業者が保護カバー３または絶縁被覆部６によって被覆された接続配線２の部位を掴んで配線ユニット１をバッテリー１００から離脱させることで、配線ユニット１の取り外しが完了する。   When removing the wiring unit 1 from the electrode terminal portion 102 of the battery 100, first, the operator turns the screw 4 similarly to the case where the screw 4 is screwed to the electrode terminal portion 102, and screws for the electrode terminal portion 102. It is sufficient to release the 4 screw connection. Thereafter, the operator grasps the portion of the connection wiring 2 covered by the protective cover 3 or the insulating coating 6 and separates the wiring unit 1 from the battery 100, whereby the removal of the wiring unit 1 is completed.

以上説明したように、本実施形態の配線ユニット１によれば、配線端子部５及びネジ４が保護カバー３内に保持される。このため、接続配線２の一方の配線端子部５がバッテリー１００の電極端子部１０２に触れている状態で、他方の配線端子部５が意図しない導体部分に触れてしまうことを抑制できる。すなわち、接続配線２をバッテリー１００の電極端子部１０２に着脱する際に、バッテリー１００が短絡することを抑制できる。
また、配線端子部５及びネジ４の両方が保護カバー３内に保持されるため、接続配線２をバッテリー１００の電極端子部１０２から取り外した状態であっても、ネジ４と接続配線２とを別個に管理する必要がない。すなわち、バッテリー１００同士を電気接続するための部品を容易に管理することができる。 As described above, according to the wiring unit 1 of the present embodiment, the wiring terminal portion 5 and the screw 4 are held in the protective cover 3. Therefore, in a state where one of the wiring terminal portions 5 of the connection wiring 2 is in contact with the electrode terminal portion 102 of the battery 100, the other wiring terminal portion 5 can be prevented from touching an unintended conductor portion. That is, when attaching and detaching connection wiring 2 to electrode terminal part 102 of battery 100, it can control that battery 100 short-circuits.
Further, since both the wiring terminal portion 5 and the screw 4 are held in the protective cover 3, even when the connection wiring 2 is removed from the electrode terminal portion 102 of the battery 100, the screw 4 and the connection wiring 2 can be There is no need to manage separately. That is, parts for electrically connecting the batteries 100 can be easily managed.

また、本実施形態の配線ユニット１によれば、保護カバー３の端子挿通孔２３が配線端子部５のネジ挿通孔１１に挿通されたネジ４を挿通不能とする形状に形成されている。このため、ネジ挿通孔１１にネジ４が挿通された状態では、配線端子部５が端子挿通孔２３を通して保護カバー３の外側に抜け出ることを防止できる。すなわち、配線端子部５及びネジ４を好適に保護カバー３内に保持できる。   Further, according to the wiring unit 1 of the present embodiment, the terminal insertion hole 23 of the protective cover 3 is formed in a shape that can not insert the screw 4 inserted into the screw insertion hole 11 of the wiring terminal portion 5. For this reason, in a state where the screw 4 is inserted into the screw insertion hole 11, the wiring terminal portion 5 can be prevented from coming out of the protective cover 3 through the terminal insertion hole 23. That is, the wiring terminal portion 5 and the screw 4 can be suitably held in the protective cover 3.

さらに、本実施形態の配線ユニット１によれば、操作用孔２４の径寸法がネジ４の頭部１９の径寸法よりも小さい、また、ネジ４の頭部１９が保護カバー３の端壁部２２に当接した状態であってもネジ４の軸部１８がネジ挿通孔１１に挿通した状態に保持される。このため、保護カバー３に操作用孔２４が形成されていても、ネジ４が操作用孔２４を通して保護カバー３の外側に抜け出ることを防ぎ、ネジ４を安定した状態で保護カバー３内に保持できる。   Furthermore, according to the wiring unit 1 of the present embodiment, the diameter of the operation hole 24 is smaller than the diameter of the head 19 of the screw 4, and the head 19 of the screw 4 is an end wall portion of the protective cover 3 Even in the state of being in contact with the pin 22, the shaft portion 18 of the screw 4 is held in the state of being inserted into the screw insertion hole 11. Therefore, even if the operation hole 24 is formed in the protective cover 3, the screw 4 is prevented from coming out of the protective cover 3 through the operation hole 24, and the screw 4 is held in the protective cover 3 in a stable state. it can.

また、本実施形態の配線ユニット１によれば、接続配線２をバッテリー１００の電極端子部１０２から取り外した状態であっても、ネジ４は配線端子部５のネジ挿通孔１１に挿通された状態に保持される。このため、作業者は配線端子部５をバッテリー１００の電極端子部１０２にネジ止めする際に、ネジ４を掴んでネジ挿通孔１１に挿通させる必要がない。これにより、作業者は、一方の手で保護カバー３または接続配線２を掴み、他方の手でドライバー等の工具を掴んでネジ４を操作することができる。したがって、配線端子部５をバッテリー１００の電極端子部１０２に対して容易にネジ止めすることができる。   Further, according to the wiring unit 1 of the present embodiment, even when the connection wiring 2 is removed from the electrode terminal portion 102 of the battery 100, the screw 4 is inserted into the screw insertion hole 11 of the wiring terminal portion 5. Will be held by Therefore, when screwing the wiring terminal portion 5 to the electrode terminal portion 102 of the battery 100, it is not necessary to hold the screw 4 and insert the screw 4 into the screw insertion hole 11. As a result, the operator can operate the screw 4 by holding the protective cover 3 or the connection wiring 2 with one hand and the tool such as a driver with the other hand. Therefore, the wiring terminal portion 5 can be easily screwed to the electrode terminal portion 102 of the battery 100.

また、本実施形態の配線ユニット１によれば、配線端子部５の他方の主面１２ｂから突出するネジ４の軸部１８の長さが、配線端子部５から保護カバー３の開口端２５までの距離よりも短く設定されている。このため、ネジ４の軸部１８が保護カバー３の外側に突出することを防止できる。これにより、ネジ４の軸部１８が意図しない導体部分に触れてしまうことを抑制できる。したがって、接続配線２をバッテリー１００の電極端子部１０２に着脱する際に、バッテリー１００が短絡することを効果的に抑制できる。   Further, according to the wiring unit 1 of the present embodiment, the length of the shaft 18 of the screw 4 protruding from the other main surface 12 b of the wiring terminal 5 is from the wiring terminal 5 to the opening end 25 of the protective cover 3 It is set shorter than the distance of. For this reason, it can prevent that the axial part 18 of the screw 4 protrudes outside the protective cover 3. Thereby, it can suppress that the axial part 18 of the screw 4 touches the conductor part which is not intended. Therefore, when the connection wiring 2 is attached to and detached from the electrode terminal portion 102 of the battery 100, a short circuit of the battery 100 can be effectively suppressed.

さらに、本実施形態の配線ユニット１によれば、保護カバー３の開口端２５が、バッテリー１００の設置面１０３に対応する形状に形成されている。このため、保護カバー３を設置面１０３に載置した状態で、設置面１０３と保護カバー３との間に隙間が生じることを抑制できる。また、保護カバー３を設置面１０３上に安定して載置することができる。   Furthermore, according to the wiring unit 1 of the present embodiment, the opening end 25 of the protective cover 3 is formed in a shape corresponding to the installation surface 103 of the battery 100. For this reason, in a state where the protective cover 3 is mounted on the installation surface 103, it can be suppressed that a gap is generated between the installation surface 103 and the protective cover 3. Also, the protective cover 3 can be stably placed on the installation surface 103.

また、本実施形態の配線ユニット１によれば、端子挿通孔２３が、保護カバー３の周壁部２１の周方向に間隔をあけて複数配列されている。このため、接続配線２を保護カバー３から様々な方向に延ばすことができる。すなわち、保護カバー３の汎用性を向上できる。この効果は、本実施形態のように、保護カバー３を載置するバッテリー１００の設置面１０３が平坦ではなく、かつ、保護カバー３の開口端２５がバッテリー１００の設置面１０３に対応する形状に形成されている場合に、特に有効である。   Further, according to the wiring unit 1 of the present embodiment, a plurality of terminal insertion holes 23 are arranged at intervals in the circumferential direction of the peripheral wall portion 21 of the protective cover 3. Thus, the connection wiring 2 can be extended from the protective cover 3 in various directions. That is, the versatility of the protective cover 3 can be improved. As in the present embodiment, the effect is that the mounting surface 103 of the battery 100 on which the protective cover 3 is placed is not flat, and the opening end 25 of the protective cover 3 corresponds to the mounting surface 103 of the battery 100. It is particularly effective if it is formed.

さらに、本実施形態の配線ユニット１によれば、端子挿通孔２３が配線端子部５の断面形状に対応する形状に形成されている。このため、端子挿通孔２３に挿通された配線端子部５が端子挿通孔２３の貫通方向を軸として回転することを抑制できる。これにより、配線端子部５やネジ４を安定した状態で保護カバー３内に保持できる。   Furthermore, according to the wiring unit 1 of the present embodiment, the terminal insertion hole 23 is formed in a shape corresponding to the cross-sectional shape of the wiring terminal portion 5. For this reason, it can suppress that the wiring terminal part 5 penetrated by the terminal penetration hole 23 rotates by setting the penetration direction of the terminal penetration hole 23 as an axis. Thereby, the wiring terminal portion 5 and the screw 4 can be held in the protective cover 3 in a stable state.

〔第二実施形態〕
次に、本発明の第二実施形態について、図５を参照して第一実施形態との相違点を中心に説明する。なお、第一実施形態と共通する構成については、同一符号を付し、その説明を省略する。 Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG. 5, focusing on differences from the first embodiment. In addition, about the structure which is common in 1st embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図５に示すように、本実施形態に係る配線ユニット１Ａは、第一実施形態の配線ユニット１と同様の接続配線２、保護カバー３Ａ及びネジ４を備える。その上で、本実施形態の配線ユニット１Ａでは、保護カバー３Ａの端壁部２２Ａが、周壁部２１の軸方向の一端を閉塞する平板状の端壁部本体３１と、端壁部本体３１から保護カバー３Ａ内に突出する筒状のリブ３２と、を備える。
端壁部２２Ａの操作用孔２４Ａは、端壁部本体３１をその板厚方向に貫通する第一孔部２４Ａ１と、リブ３２によって画定され、第一孔部２４Ａ１に連なる第二孔部２４Ａ２と、を備える。すなわち、本実施形態の操作用孔２４Ａは、第一実施形態と比較して、リブ３２によって保護カバー３Ａ内に向けて延長されている。 As shown in FIG. 5, the wiring unit 1A according to the present embodiment includes the connection wiring 2, the protective cover 3A, and the screw 4 similar to the wiring unit 1 of the first embodiment. In addition, in the wiring unit 1A of the present embodiment, the end wall 22A of the protective cover 3A is a flat end wall main body 31 that closes one end in the axial direction of the peripheral wall 21; And a cylindrical rib 32 protruding into the protective cover 3A.
The operation hole 24A of the end wall 22A is defined by a first hole 24A1 penetrating the end wall main body 31 in the thickness direction thereof and a rib 32, and a second hole 24A2 continuing to the first hole 24A1 And. That is, compared to the first embodiment, the operation hole 24A of the present embodiment is extended toward the inside of the protective cover 3A by the rib 32.

操作用孔２４Ａの径寸法は、例えば図５のように一定であってもよいが、例えば保護カバー３Ａの内側に向かうにしたがって小さくなってもよい。この場合、リブ３２の突出方向先端における操作用孔２４Ａの径寸法が、ネジ４の頭部１９の径寸法よりも小さければよい。リブ３２の突出方向先端を除く操作用孔２４Ａの径寸法は、例えばネジ４の頭部１９の径寸法と同等以上であってもよい。   The diameter dimension of the operation hole 24A may be constant, for example, as shown in FIG. 5, but may be smaller toward the inside of the protective cover 3A, for example. In this case, the diameter of the operation hole 24A at the tip of the rib 32 in the protruding direction may be smaller than the diameter of the head 19 of the screw 4. The diameter dimension of the operation hole 24A excluding the tip in the protruding direction of the rib 32 may be equal to or greater than the diameter dimension of the head 19 of the screw 4, for example.

本実施形態の配線ユニット１Ａによれば、第一実施形態と同様の効果を奏する。
さらに、本実施形態の配線ユニット１Ａによれば、仮に端壁部本体３１の板厚が薄くても、ネジ４の頭部１９の形状に関わらず、ネジ４の頭部１９が操作用孔２４Ａから保護カバー３Ａの外側に突出することを防止できる。これにより、ネジ４の頭部１９が意図しない導体部分に触れてしまうことを効果的に抑制できる。したがって、接続配線２をバッテリー１００の電極端子部１０２に着脱する際に、バッテリー１００が短絡することを効果的に抑制できる。 According to the wiring unit 1A of the present embodiment, the same effects as the first embodiment can be obtained.
Furthermore, according to the wiring unit 1A of this embodiment, even if the plate thickness of the end wall main body 31 is thin, the head 19 of the screw 4 is the operation hole 24A regardless of the shape of the head 19 of the screw 4. Can be prevented from protruding outside the protective cover 3A. Thereby, it can be effectively suppressed that the head 19 of the screw 4 touches an unintended conductor portion. Therefore, when the connection wiring 2 is attached to and detached from the electrode terminal portion 102 of the battery 100, a short circuit of the battery 100 can be effectively suppressed.

〔第三実施形態〕
次に、本発明の第三実施形態について、図６，７を参照して第一、第二実施形態との相違点を中心に説明する。なお、第一、第二実施形態と共通する構成については、同一符号を付し、その説明を省略する。 Third Embodiment
Next, a third embodiment of the present invention will be described with reference to FIGS. 6 and 7, focusing on differences from the first and second embodiments. In addition, about the structure which is common in 1st, 2nd embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図６，７に示すように、本実施形態に係る配線ユニット１Ｂは、第一、第二実施形態の配線ユニット１，１Ａと同様の接続配線２、保護カバー３Ｂ及びネジ４を備える。その上で、本実施形態の配線ユニット１Ｂでは、配線端子部５が保護カバー３Ｂに固定される。以下、この点について具体的に説明する。   As shown in FIGS. 6 and 7, the wiring unit 1B according to the present embodiment includes the connection wiring 2, the protective cover 3B, and the screw 4 similar to the wiring units 1 and 1A of the first and second embodiments. Then, in the wiring unit 1B of the present embodiment, the wiring terminal portion 5 is fixed to the protective cover 3B. Hereinafter, this point will be specifically described.

本実施形態の保護カバー３Ｂの周壁部２１の内面には、保護カバー３Ｂ内に配された配線端子部５を板厚方向から挟み込む狭持部３４が設けられている。
狭持部３４は、周壁部２１の内面から突出し、配線端子部５の板厚方向に間隔をあけて配された一対の狭持凸部３５，３５を備える。一対の狭持凸部３５，３５同士の間隔は、例えば配線端子部５の板厚に対して同等または若干小さい。配線端子部５は、一対の狭持凸部３５，３５の間に嵌め入れられることで、保護カバー３Ｂに固定される。 On the inner surface of the peripheral wall portion 21 of the protective cover 3B of the present embodiment, a pinching portion 34 for sandwiching the wiring terminal portion 5 disposed in the protective cover 3B in the thickness direction is provided.
The pinching portion 34 includes a pair of pinching convex portions 35 and 35 which protrude from the inner surface of the peripheral wall portion 21 and are spaced apart in the thickness direction of the wiring terminal portion 5. The distance between the pair of holding convex portions 35, 35 is equal to or slightly smaller than the thickness of the wiring terminal portion 5, for example. The wiring terminal portion 5 is fixed to the protective cover 3B by being fitted between the pair of holding convex portions 35, 35.

狭持部３４は、周壁部２１の内面のうち、例えば端子挿通孔２３から保護カバー３Ｂ内に挿入される配線端子部５の挿入方向（図７において左方向）の前側の領域に設けられてもよい。ただし、本実施形態において、狭持部３４は、保護カバー３Ｂを図６のように配線端子部５の挿入方向から見て、配線端子部５の幅方向（図６における左右方向）において端子挿通孔２３の両側部に隣り合う領域に設けられる。すなわち、本実施形態では、一対の狭持部３４，３４が、互いに対向するように設けられ、保護カバー３Ｂ内に収容された配線端子部５の幅方向の両端部を支持する。   The pinching portion 34 is provided in a region on the front side in the insertion direction (left direction in FIG. 7) of the wiring terminal portion 5 inserted into the protective cover 3B from the terminal insertion hole 23 among the inner surfaces of the peripheral wall portion 21. It is also good. However, in the present embodiment, when the protective cover 3B is viewed from the insertion direction of the wiring terminal portion 5 as shown in FIG. 6, the pinching portion 34 inserts the terminal in the width direction of the wiring terminal portion 5 (horizontal direction in FIG. It is provided in the area adjacent to both sides of the hole 23. That is, in the present embodiment, the pair of sandwiching portions 34, 34 are provided to face each other, and support both end portions in the width direction of the wiring terminal portion 5 accommodated in the protective cover 3B.

また、各狭持部３４は、配線端子部５が安定して保護カバー３Ｂ内に挿入されるように形成されている。各狭持部３４は、例えば配線端子部５の挿入方向に複数に分けて形成されてもよいが、本実施形態では、配線端子部５の挿入方向に延びて形成されている。   Each of the holding portions 34 is formed so that the wiring terminal portion 5 can be stably inserted into the protective cover 3B. The respective holding portions 34 may be formed, for example, in a plurality in the insertion direction of the wiring terminal portion 5, but in the present embodiment, the holding portions 34 are formed extending in the insertion direction of the wiring terminal portion 5.

本実施形態の配線ユニット１Ｂによれば、第一、第二実施形態と同様の効果を奏する。
また、本実施形態の配線ユニット１Ｂによれば、配線端子部５が保護カバー３Ｂに固定される。このため、配線端子部５を安定した状態で保護カバー３Ｂ内に保持できる。 According to the wiring unit 1B of the present embodiment, the same effects as in the first and second embodiments can be obtained.
Further, according to the wiring unit 1B of the present embodiment, the wiring terminal portion 5 is fixed to the protective cover 3B. Therefore, the wiring terminal portion 5 can be held in the protective cover 3B in a stable state.

また、本実施形態の配線ユニット１Ｂでは、保護カバー３Ｂ内に収容された配線端子部５の幅方向の両端部が一対の狭持部３４，３４によって支持される。このため、配線端子部５を特に安定した状態で保護カバー３Ｂ内に保持できる。   Further, in the wiring unit 1B of the present embodiment, both end portions in the width direction of the wiring terminal portion 5 accommodated in the protective cover 3B are supported by the pair of sandwiching portions 34, 34. Therefore, the wiring terminal portion 5 can be held in the protective cover 3B in a particularly stable state.

〔第四実施形態〕
次に、本発明の第四実施形態について、図８を参照して第一〜第三実施形態との相違点を中心に説明する。なお、第一〜第三実施形態と共通する構成については、同一符号を付し、その説明を省略する。 Fourth Embodiment
Next, a fourth embodiment of the present invention will be described with reference to FIG. 8, focusing on differences from the first to third embodiments. In addition, about the structure in common with 1st-3rd embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図８に示すように、本実施形態に係る配線ユニット１Ｃは、第一〜第三実施形態の配線ユニット１，１Ａ，１Ｂと同様の接続配線２、保護カバー３Ｃ及びネジ４を備える。その上で、本実施形態の配線ユニット１Ｃでは、保護カバー３Ｃが互いに着脱可能に固定される複数のカバー分割体４１，４２によって構成される。保護カバー３Ｃは、例えば、端子挿通孔２３（図１〜７参照）が二つ以上のカバー分割体４１，４２を組み合わせることで構成されるように、複数のカバー分割体４１，４２に分けて形成されるとよい。   As shown in FIG. 8, the wiring unit 1C according to the present embodiment includes the connection wiring 2, the protective cover 3 </ b> C and the screw 4 similar to the wiring units 1, 1A and 1B of the first to third embodiments. In addition, in the wiring unit 1C according to the present embodiment, the protective cover 3C is configured by the plurality of cover divisions 41 and 42 to which the protective cover 3C is detachably fixed. The protective cover 3C is divided into a plurality of cover divisions 41 and 42 so that, for example, the terminal insertion hole 23 (see FIGS. 1 to 7) is formed by combining two or more cover divisions 41 and 42. It should be formed.

本実施形態の保護カバー３Ｃは、二つのカバー分割体４１，４２に分けられる。二つのカバー分割体４１，４２は、例えば保護カバー３Ｃの端壁部２２Ａ及び周壁部２１Ｃの両方が二つに分割されるように周壁部２１Ｃの軸方向に直交する方向に配列されてもよいが、本実施形態では、保護カバー３Ｃの周壁部２１Ｃだけが二つに分割されるように、周壁部２１Ｃの軸方向に配列される。
第一カバー分割体４１は、保護カバー３Ｃの端壁部２２Ａと、周壁部２１Ｃのうち軸方向において端壁部２２Ａに連なる部位と、を構成する。一方、第二カバー分割体４２は、周壁部２１Ｃのうち保護カバー３Ｃの開口端２５を含む部位を構成する。これら二つのカバー分割体４１，４２は、第一カバー分割体４１のうち第二カバー分割体４２側の端部が第二カバー分割体４２の内側に入り込むように形成されている。 The protective cover 3C of the present embodiment is divided into two cover divisions 41 and 42. The two cover divisions 41 and 42 may be arranged in a direction perpendicular to the axial direction of the peripheral wall 21C so that, for example, both the end wall 22A and the peripheral wall 21C of the protective cover 3C are divided into two. However, in the present embodiment, only the peripheral wall 21C of the protective cover 3C is arranged in the axial direction of the peripheral wall 21C so as to be divided into two.
The first cover division body 41 constitutes an end wall portion 22A of the protective cover 3C and a portion of the peripheral wall portion 21C that is continuous with the end wall portion 22A in the axial direction. On the other hand, the second cover division body 42 constitutes a portion including the opening end 25 of the protective cover 3C in the peripheral wall portion 21C.

各被係止部４４は、少なくとも係止爪４３の鉤部４５が被係止部４４に引っ掛かることで二つのカバー分割体４１，４２の相互の脱離を防ぐように形成されていればよい。各被係止部４４は、例えば周壁部２１Ｃを径方向に貫通する係止孔であってもよいが、本実施形態では、周壁部２１Ｃの内面から窪む有底の係止凹部である。 The pair of engaged portions 44 is formed at an end portion of the second cover divided body 42 on the first cover divided body 41 side. Similar to the pair of locking claws 43, 43, the pair of locked parts 44, 44 are disposed at positions facing each other in the radial direction of the peripheral wall 21C.
Each locked portion 44 may be formed to prevent mutual detachment of the two cover divisions 41 and 42 by at least the hook portion 45 of the locking claw 43 being hooked on the locked portion 44. . Each locking portion 44 may be, for example, a locking hole penetrating the peripheral wall portion 21C in the radial direction, but in the present embodiment, it is a bottomed locking recess recessed from the inner surface of the peripheral wall portion 21C.

本実施形態において、被係止部４４には、係止爪４３の鉤部４５の他に、後述するように配線端子部５の一部も入り込む。このため、周壁部２１Ｃの軸方向に沿う被係止部４４の寸法（軸方向寸法）は、周壁部２１Ｃの軸方向に沿う鉤部４５の寸法（軸方向寸法）よりも長く設定されている。   In the present embodiment, in addition to the hook portion 45 of the locking claw 43, a part of the wiring terminal portion 5 also enters the locked portion 44 as described later. Therefore, the dimension (axial direction dimension) of the engaged portion 44 along the axial direction of the peripheral wall portion 21C is set longer than the dimension (axial direction dimension) of the flange 45 along the axial direction of the peripheral wall portion 21C. .

さらに、本実施形態の配線ユニット１Ｃでは、配線端子部５が二つのカバー分割体４１，４２の間に挟み込まれることで保護カバー３Ｃに固定される。本実施形態では、配線端子部５の幅方向（図８において左右方向）の両端部が、二つのカバー分割体４１，４２の間に挟み込まれる。
配線端子部５を挟み込むための二つのカバー分割体４１，４２の構成や形状は、任意であってよいが、本実施形態では、第一カバー分割体４１の係止爪４３と、第二カバー分割体４２の被係止部４４とによって構成される。配線端子部５の幅方向の両端部は、第一カバー分割体４１の係止爪４３と、第二カバー分割体４２の被係止部４４との間に挟み込まれる。言い換えれば、配線端子部５は、その幅方向の両端部が係止爪４３の鉤部４５と共に被係止部４４に係止されることで、保護カバー３Ｃに固定される。 Furthermore, in the wiring unit 1C of the present embodiment, the wiring terminal portion 5 is fixed to the protective cover 3C by being sandwiched between the two cover divisions 41 and 42. In the present embodiment, both end portions in the width direction (the left and right direction in FIG. 8) of the wiring terminal portion 5 are sandwiched between the two cover divisions 41 and 42.
The configuration and shape of the two cover divisions 41 and 42 for sandwiching the wiring terminal portion 5 may be arbitrary, but in the present embodiment, the locking claws 43 of the first cover division 41 and the second cover It is comprised by the to-be-locked part 44 of the division body 42. As shown in FIG. Both end portions in the width direction of the wiring terminal portion 5 are sandwiched between the locking claws 43 of the first cover divided body 41 and the locked portions 44 of the second cover divided body 42. In other words, the wiring terminal portion 5 is fixed to the protective cover 3C by the both end portions in the width direction being locked to the locked portion 44 together with the flange portion 45 of the locking claw 43.

次に、上記構成の配線ユニット１Ｃを組み立てる方法、具体的には、配線端子部５及びネジ４を保護カバー３Ｃ内に保持させる方法について説明する。   Next, a method of assembling the wiring unit 1C configured as described above, specifically, a method of holding the wiring terminal portion 5 and the screw 4 in the protective cover 3C will be described.

The screw 4 may be disposed in the second cover division 42.

最後に、二つの分割体を相互に固定する固定工程を実施することで、配線ユニット１Ｃの組み立てが完了する。
本実施形態の固定工程では、二つのカバー分割体４１，４２を相互に固定することで、配線端子部５を二つのカバー分割体４１，４２の間に挟み込み、配線端子部５を保護カバー３Ｃに固定する。より具体的に説明すれば、本実施形態の固定工程では、二つのカバー分割体４１，４２を相互に固定する際に、第一カバー分割体４１の係止爪４３を第二カバー分割体４２の被係止部４４に係止させる。これにより、二つのカバー分割体４１，４２が相互に固定される。また、配線端子部５が、係止爪４３と被係止部４４との間に挟み込まれることで、保護カバー３Ｃに固定される。 Finally, the assembly process of the wiring unit 1C is completed by performing the fixing process of fixing the two divided bodies to each other.
In the fixing step of this embodiment, the two cover divisions 41 and 42 are fixed to each other to sandwich the wiring terminal portion 5 between the two cover divisions 41 and 42, and the wiring terminal portion 5 to the protective cover 3C. Fix to More specifically, in the fixing step of the present embodiment, when the two cover divisions 41 and 42 are fixed to each other, the locking claw 43 of the first cover division 41 is a second cover division 42. Is locked to the locked portion 44 of the Thereby, the two cover divisions 41 and 42 are mutually fixed. Further, the wiring terminal portion 5 is fixed to the protective cover 3C by being sandwiched between the locking claw 43 and the locked portion 44.

上記のように組み立てられる本実施形態の配線ユニット１Ｃにおいて、二つのカバー分割体４１，４２を相互に脱離する場合には、一対の係止爪４３，４３の鉤部４５が相互に近づくように一対の係止爪４３，４３を弾性的に撓み変形させた状態で、二つのカバー分割体４１，４２を相互に離す方向に移動させればよい。   In the wiring unit 1C according to the present embodiment assembled as described above, when the two cover divisions 41 and 42 are detached from each other, the collar portions 45 of the pair of locking claws 43 and 43 may be brought closer to each other The two cover divisions 41 and 42 may be moved in the direction in which they are separated from each other in a state in which the pair of locking claws 43 and 43 are elastically bent and deformed.

本実施形態の配線ユニット１Ｃによれば、第一〜第三実施形態と同様の効果を奏する。
また、本実施形態の配線ユニット１Ｃによれば、保護カバー３Ｃが互いに着脱可能に固定される二つのカバー分割体４１，４２によって構成されている。このため、配線端子部５及びネジ４を二つのカバー分割体４１，４２の一方（本実施形態において第二カバー分割体４２）に配置した後に、二つのカバー分割体４１，４２を互いに固定することで、配線端子部５及びネジ４を容易に保護カバー３Ｃ内に保持させることができる。言い換えれば、配線端子部５にネジ４及び保護カバー３Ｃを容易に取り付けることができる。 According to the wiring unit 1C of the present embodiment, the same effects as in the first to third embodiments can be obtained.
Further, according to the wiring unit 1C of the present embodiment, the protective cover 3C is configured by the two cover divisions 41 and 42, which are detachably fixed to each other. Therefore, after arranging the wiring terminal portion 5 and the screw 4 on one of the two cover divisions 41 and 42 (the second cover division 42 in the present embodiment), the two cover divisions 41 and 42 are fixed to each other. Thus, the wiring terminal portion 5 and the screw 4 can be easily held in the protective cover 3C. In other words, the screw 4 and the protective cover 3C can be easily attached to the wiring terminal portion 5.

さらに、本実施形態の配線ユニット１Ｃによれば、配線端子部５が二つのカバー分割体４１，４２の間に挟み込まれることで、保護カバー３Ｃに固定される。このため、配線端子部５を容易に保護カバー３Ｃに固定することができる。   Furthermore, according to the wiring unit 1C of the present embodiment, the wiring terminal portion 5 is fixed to the protective cover 3C by being sandwiched between the two cover divisions 41 and 42. Therefore, the wiring terminal portion 5 can be easily fixed to the protective cover 3C.

上記第四実施形態において、配線端子部５は、例えば図９に示すように、二つのカバー分割体４１，４２の間に挟み込まれなくてもよい。この場合、被係止部４４の軸方向寸法は、鉤部４５の軸方向寸法と同等に設定されればよい。これにより、一対の係止爪４３，４３が一対の被係止部４４，４４に係止した状態で、二つのカバー分割体４１，４２が周壁部２１Ｃの軸方向に相互に移動することを防止できる。すなわち、二つのカバー分割体４１，４２を相互に固定することができる。
図９に例示する配線ユニット１Ｄにおいては、例えば第三実施形態の狭持部３４をいずれか一方のカバー分割体４１，４２に設けてもよい。 In the fourth embodiment, the wiring terminal portion 5 may not be sandwiched between the two cover divisions 41 and 42 as shown in FIG. 9, for example. In this case, the axial dimension of the engaged portion 44 may be set to be equal to the axial dimension of the collar 45. Thus, with the pair of locking claws 43, 43 being locked to the pair of locked portions 44, 44, the two cover divisions 41, 42 move relative to each other in the axial direction of the peripheral wall 21C. It can prevent. That is, the two cover divisions 41 and 42 can be fixed to each other.
In the wiring unit 1D illustrated in FIG. 9, for example, the pinching portion 34 of the third embodiment may be provided in one of the cover divisions 41 and 42.

また、上記第四実施形態においては、例えば、一対の係止爪４３，４３が第二カバー分割体４２に設けられ、一対の被係止部４４，４４が第一カバー分割体４１に設けられてもよい。   Moreover, in the said 4th embodiment, a pair of latching claws 43 and 43 are provided in the 2nd cover division body 42, and a pair of to-be-locked part 44 and 44 is provided in the 1st cover division body 41, for example.

以上、本発明の詳細について説明したが、本発明は上述した実施形態に限定されるものではなく、本発明の主旨を逸脱しない範囲において種々の変更を加えることができる。   As mentioned above, although the detail of the present invention was explained, the present invention is not limited to the embodiment mentioned above, and various change can be added in the range which does not deviate from the main point of the present invention.

例えば、第三、第四実施形態では、配線端子部５全体が保護カバー３Ｂ，３Ｃに直接固定されるが、例えば図１０（ａ）に示すように、配線端子部５Ｅの一部だけが保護カバー３Ｅに直接固定されてもよい。以下、図１０に例示した構成について説明する。   For example, in the third and fourth embodiments, the entire wiring terminal portion 5 is directly fixed to the protective covers 3B and 3C, but only a part of the wiring terminal portion 5E is protected as shown in, for example, FIG. It may be fixed directly to the cover 3E. Hereinafter, the configuration illustrated in FIG. 10 will be described.

図１０（ａ）に例示する配線ユニット１Ｅは、第一、第二実施形態と同様に、接続配線２Ｅ、保護カバー３Ｅ及びネジ４を備える。図１０（ａ）の構成において、接続配線２Ｅは、導電性を有する線材からなる配線本体（不図示）と、配線本体の長手方向の両端に接続される配線端子部５Ｅと、を備える。配線端子部５Ｅは、中継端子板５１と、中継端子板５１に対して着脱可能に固定される圧着端子５２と、を備える。   A wiring unit 1E illustrated in FIG. 10A includes a connection wiring 2E, a protective cover 3E, and a screw 4 as in the first and second embodiments. In the configuration of FIG. 10A, the connection wiring 2E includes a wiring main body (not shown) made of a conductive wire material and wiring terminal portions 5E connected to both ends in the longitudinal direction of the wiring main body. The wiring terminal portion 5E includes a relay terminal plate 51 and a crimp terminal 52 fixed to the relay terminal plate 51 so as to be removable.

中継端子板５１は、平板状に形成され、保護カバー３Ｅに直接固定される。中継端子板５１を保護カバー３Ｅに固定する手法は、第三、第四実施形態と同様であってよい。
中継端子板５１には、ネジ４を挿通させるネジ挿通孔１１が形成されている。すなわち、図１０（ａ）に示す配線ユニット１Ｅでは、中継端子板５１がネジ４によってバッテリー１００の電極端子部１０２にネジ止め固定される。また、中継端子板５１には、圧着端子５２を中継端子板５１にネジ止めするためのネジ止め部５３が設けられている。ネジ挿通孔１１とネジ止め部５３とは、互いに間隔をあけて位置している。 The relay terminal plate 51 is formed in a flat plate shape, and is directly fixed to the protective cover 3E. The method of fixing the relay terminal plate 51 to the protective cover 3E may be the same as in the third and fourth embodiments.
The relay terminal plate 51 is formed with a screw insertion hole 11 through which the screw 4 is inserted. That is, in the wiring unit 1E shown in FIG. 10A, the relay terminal plate 51 is screwed and fixed to the electrode terminal portion 102 of the battery 100 by the screw 4. Further, the relay terminal plate 51 is provided with a screwing portion 53 for screwing the crimp terminal 52 to the relay terminal plate 51. The screw insertion hole 11 and the screwing portion 53 are positioned spaced apart from each other.

圧着端子５２は、配線本体に対して着脱不能に固定される。圧着端子５２は、中継端子板５１にネジ止め可能な形状に形成されている。圧着端子５２の形状は、図１０（ｂ）に例示する丸形（円環形状）であってもよいが、例えば先開形であってもよい。   The crimp terminal 52 is non-removably fixed to the wiring main body. The crimp terminal 52 is formed in a shape that can be screwed to the relay terminal plate 51. The shape of the crimp terminal 52 may be a round shape (ring shape) illustrated in FIG. 10B, but may be, for example, a front-opened shape.

図１０に例示する配線ユニット１Ｅによれば、同一種類の中継端子板５１に対し、様々な形状や大きさの圧着端子５２をネジ止めすることができる。また、保護カバー３Ｅには、圧着端子５２の形状や大きさに関わらず、同一種類の中継端子板５１を固定できる。すなわち、同一種類の保護カバー３Ｅを用いても、様々な形状や大きさの圧着端子５２を保護カバー３Ｅに固定することができる。したがって、保護カバー３Ｅの汎用性を向上することができる。   According to the wiring unit 1E illustrated in FIG. 10, the crimp terminals 52 of various shapes and sizes can be screwed to the relay terminal plate 51 of the same type. In addition, regardless of the shape and size of the crimp terminal 52, the relay terminal plate 51 of the same type can be fixed to the protective cover 3E. That is, even if protective covers 3E of the same type are used, crimp terminals 52 of various shapes and sizes can be fixed to the protective cover 3E. Therefore, the versatility of the protective cover 3E can be improved.

図１０に例示した配線ユニット１Ｅにおいて、保護カバー３Ｅの端子挿通孔２３は、例えば第一実施形態と同様に配線端子部５Ｅ全体が挿通されるように形成されてもよいが、例えば配線端子部５Ｅのうち圧着端子５２のみが挿通されるように形成されてもよい。このため、貫通方向から見た端子挿通孔２３の形状は、例えば第一実施形態と同様に配線端子部５Ｅ全体の断面形状に相似する形状であってもよいが、例えば圧着端子５２の断面形状に相似する形状に形成されてもよい。   In the wiring unit 1E illustrated in FIG. 10, the terminal insertion hole 23 of the protective cover 3E may be formed, for example, so that the entire wiring terminal portion 5E may be inserted as in the first embodiment. Of the terminals 5E, only the crimp terminal 52 may be inserted. Therefore, the shape of the terminal insertion hole 23 viewed from the penetration direction may be similar to the cross-sectional shape of the entire wiring terminal portion 5E as in the first embodiment, for example. It may be formed in a similar shape.

また、上記した全ての実施形態において、保護カバー３，３Ａ，３Ｂ，３Ｃ，３Ｅの端子挿通孔２３は、その貫通方向から見て、配線端子部５，５Ｅの断面形状（または配線端子部５Ｅの圧着端子５２の断面形状）に相似する形状に形成されているが、少なくとも配線端子部５，５Ｅのネジ挿通孔１１に挿通されたネジ４を挿通不能とする形状に形成されていればよい。したがって、端子挿通孔２３は、例えば配線端子部５，５Ｅの断面形状に相似しない形状に形成されてもよい。   Further, in all the embodiments described above, the terminal insertion holes 23 of the protective covers 3, 3A, 3B, 3C, 3E have the cross-sectional shapes of the wiring terminal portions 5, 5E (or the wiring terminal portions 5E) The cross-sectional shape of the crimp terminal 52 is formed in a shape similar to that of the crimped terminal 52. However, it may be formed in a shape that makes it impossible to insert at least the screw 4 inserted into the screw insertion hole 11 of the wiring terminals 5 and 5E. . Therefore, the terminal insertion hole 23 may be formed, for example, in a shape not similar to the cross-sectional shape of the wiring terminal portions 5 and 5E.

また、本発明の配線ユニットは、バッテリー同士の接続に適用されることに限らず、例えばバッテリーと他の機器との接続に適用されてもよい。他の機器には、例えばバッテリーに電力を供給するための充電機器や、バッテリーの電力が供給されて動作する負荷機器などが含まれる。また、本発明の配線ユニットは、例えば、バッテリー以外の電力供給源と負荷機器との接続に適用されてもよい。   Further, the wiring unit of the present invention is not limited to the connection between the batteries, and may be applied, for example, to the connection between the battery and another device. Other devices include, for example, a charging device for supplying power to a battery, and a load device which operates by being supplied with battery power. In addition, the wiring unit of the present invention may be applied to, for example, connection between a power supply source other than a battery and a load device.
