本発明は、電線と保持金具との接続構造に関する。   The present invention relates to a connection structure between an electric wire and a holding fitting.

特許文献１に記載された端子金具は、所定形状に打ち抜いた金属板材を曲げ加工して形成されおり、長手に延びる基底部と、一対のカシメ片と、接続部と、アーム部とを備えている。
前記一対のカシメ片は、前記基底部の左右両側縁から延設され、シールド電線のシースの外周上に折り返された編組線を介してシースにかしめられる。 The terminal fitting described in Patent Literature 1 is formed by bending a metal plate material punched into a predetermined shape, and includes a base portion extending in a longitudinal direction, a pair of caulking pieces, a connecting portion, and an arm portion.

しかしながら、基底部の長手方向（電線の長手方向に相当）に関して、接続部の位置を、一対のカシメ片から離隔した位置に配置することが必要である。このため、電線を保持する端子金具が、電線の長手方向に大型化する。また、アーム部は、シースの外周の一部にしか巻かれておらず、かしめ保持力が弱い。
本発明の目的は、小型で、かしめ保持力が高い、電線と保持金具の接続構造を提供することである。 However, with respect to the longitudinal direction of the base portion (corresponding to the longitudinal direction of the electric wire), it is necessary to arrange the connection portion at a position separated from the pair of caulking pieces. For this reason, the terminal fitting for holding the electric wire is enlarged in the longitudinal direction of the electric wire. Further, the arm portion is wound around only a part of the outer periphery of the sheath, and has a weak swaging and holding force.
An object of the present invention is to provide a connection structure between an electric wire and a holding fitting, which is small in size and has a high caulking holding force.

請求項１に記載の発明は、長手方向（Ｘ）に延びる電線（２０）と、巻回始端（５０ｓ）から巻回終端（５０ｅ）まで前記電線の周囲に所定の巻き方向に一回りを超えて巻回されて重合領域（ＯＬ）を形成する状態で前記電線にかしめ固定されたかしめ固定部（５０）と、前記巻回始端と直接又は介在部（６２；６３）を介して間接的に接続され、取付対象に取り付けられる被取付部（６０）と、を含む保持金具（３０；３０Ｐ；３０Ｑ）と、を備え、前記かしめ固定部の少なくとも一部と前記被取付部の少なくとも一部とは、前記電線の前記長手方向の位置が重なっている、電線と保持金具との接続構造（１０；１０Ｐ；１０Ｑ）を提供する。   According to the first aspect of the present invention, the electric wire (20) extending in the longitudinal direction (X) and the winding from the winding start end (50s) to the winding end (50e) around the electric wire in the predetermined winding direction exceed one turn. And a crimp fixing portion (50) fixed to the electric wire in a state of being wound to form an overlap region (OL), directly with the winding start end or indirectly through an interposition portion (62; 63). A holding part (30; 30P; 30Q) including a mounting part (60) connected and mounted to the mounting target, and at least a part of the caulking fixing part and at least a part of the mounting part. Provides a connection structure (10; 10P; 10Q) between the electric wire and the holding bracket, wherein the position of the electric wire in the longitudinal direction overlaps.

なお、括弧内の英数字は、後述する実施形態における対応構成要素等を表すが、このことは、むろん、本発明がそれらの実施形態に限定されるべきことを意味するものではない。以下、この項において同じ。
請求項２に記載の発明のように、前記介在部が、前記巻回始端に沿って前記電線の前記長手方向と平行に延びる第１接続縁（６６）を介して前記巻回始端と接続された第１板部（６４）と、第２接続縁（６７）を介して前記第１板部と交差状に接続され第３接続縁（６８）を介して前記被取付部と交差状に接続された第２板部（６５）と、を含んでいてもよい。 The alphanumeric characters in parentheses indicate corresponding components in the embodiments described later, but this does not mean, of course, that the present invention should be limited to those embodiments. Hereinafter, the same applies in this section.
As in the invention according to claim 2, the intervening portion is connected to the winding start end via a first connection edge (66) extending parallel to the longitudinal direction of the electric wire along the winding start end. The first plate portion (64) is connected to the first plate portion via a second connection edge (67) in an intersecting manner, and is connected to the attached portion via a third connection edge (68) in an intersecting manner. A second plate portion (65).

請求項３に記載の発明のように、前記電線の前記長手方向に沿って見て、前記かしめ固定部が、前記重合領域に配置されたコーナー部（５７）を含む多角形形状に形成されていてもよい。   As in the invention according to claim 3, as viewed along the longitudinal direction of the electric wire, the caulking fixing portion is formed in a polygonal shape including a corner portion (57) arranged in the overlap region. You may.

請求項１に記載の発明では、巻回始端から巻回終端まで所定の巻き方向に一回りを超えて巻回されたかしめ固定部が、重合領域を形成する状態で電線にかしめ固定されている。このため、かしめ固定部の開きが抑制されて、かしめ保持力が高くなる。また、被取付部が、巻回始端と直接又は介在部を介して間接的に接続されており、被取付部の少なくとも一部と、かしめ固定部の少なくとも一部とは、電線の長手方向に関する位置が重なっている。このため、小型化を達成することができる。   According to the first aspect of the present invention, the caulked fixing portion wound beyond one turn in the predetermined winding direction from the winding start end to the winding end is swaged and fixed to the electric wire in a state of forming the overlap region. . For this reason, the opening of the caulking fixing portion is suppressed, and the caulking holding force increases. Further, the attached portion is directly or indirectly connected to the winding start end via an interposed portion, and at least a part of the attached portion and at least a portion of the caulking fixing portion are related to the longitudinal direction of the electric wire. Positions overlap. Therefore, downsizing can be achieved.

請求項２に記載の発明では、第１接続縁と第２接続縁との位置関係や、第２接続縁と第３接続縁との位置関係や、第１板部と第２板部との交差角度や、第２板部と被取付部との交差角度の設定により、取付対象に対して所要の取付位置や所要の取付角度を得ることができる。このため、小型化を達成しつつ、取付の自由度を向上することができる。
請求項３に記載の発明では、多角形形状を形成するかしめ固定部において、重合領域に配置されたコーナー部では、重合内側部分の開きが重合外側部分によって抑制される。このため、かしめ保持力を向上することができる。 According to the invention described in claim 2, the positional relationship between the first connecting edge and the second connecting edge, the positional relationship between the second connecting edge and the third connecting edge, and the relationship between the first plate portion and the second plate portion. By setting the crossing angle and the crossing angle between the second plate portion and the mounted portion, a required mounting position and a required mounting angle with respect to the mounting target can be obtained. For this reason, the degree of freedom of attachment can be improved while achieving downsizing.
According to the third aspect of the invention, in the caulking fixing portion that forms the polygonal shape, in the corner portion arranged in the overlapping region, the opening of the overlapping inner portion is suppressed by the overlapping outer portion. For this reason, the caulking holding force can be improved.

Thereby, a predetermined range of the braided wire 22 is exposed from the terminal 20a.
Next, in a braided wire folding step shown in FIG. 4D, the exposed portion of the braided wire 22 is folded out of the sleeve material 400 to form a folded portion 22a of the braided wire 22.

次いで、図４（ｅ）及び（ｆ）にされる保持金具素材装着工程では、シールド電線２０の長手方向Ｘから折り返し部２２ａを包囲するように保持金具素材７０を装着する。
具体的には、保持金具素材７０は、被取付部６０に相当する平板状の第１板部７１と、第１下側コーナー部５７の外側部分に相当する円弧板状の第２板部７２と、下底部５２の外側部分に相当する平板状の第３板部７３と、円弧板状の第４板部７４とを含む。 4E and 4F, the holding metal material 70 is mounted so as to surround the folded portion 22a from the longitudinal direction X of the shielded electric wire 20.
Specifically, the holding member material 70 includes a flat plate-shaped first plate portion 71 corresponding to the attached portion 60 and an arc-shaped plate-shaped second plate portion 72 corresponding to an outer portion of the first lower corner portion 57. And a third plate portion 73 in a flat plate shape corresponding to an outer portion of the lower bottom portion 52, and a fourth plate portion 74 in an arc plate shape.

第４板部７４は、第３板部７３に接続された基端部７４ａと、第２板部７２の内側に隙間を設けて近接され、巻回終端５０ｅを形成するための先端部７４ｂとを含む。平坦な第３板部７３と円弧板状の第４板部７４とによって形成された挿通空間Ｓ内に、シールド電線２０が挿通される。
次いで、図５（ａ）及び（ｂ）に示されるかしめ工程では、シールド電線２０が挿通された状態の保持金具素材７０が、かしめ型１００の下型８０上に配置された後、かしめ型１００の上型９０が下降されることにより、下型８０と上型９０との間に形成されたキャビティＣの内面によって台形状にかしめられる。 The fourth plate portion 74 has a base end portion 74a connected to the third plate portion 73 and a front end portion 74b for forming a winding end 50e which is close to the inside of the second plate portion 72 with a gap therebetween. including. The shielded electric wire 20 is inserted into the insertion space S formed by the flat third plate 73 and the arc-shaped fourth plate 74.
Next, in the caulking step shown in FIGS. 5A and 5B, after the holding member material 70 in which the shielded wire 20 is inserted is placed on the lower mold 80 of the caulking mold 100, the caulking mold 100 When the upper die 90 is lowered, the inner surface of the cavity C formed between the lower die 80 and the upper die 90 caulks in a trapezoidal shape.

具体的には、下型８０は、それぞれキャビティＣの内面の一部を形成する、下底部形成部８１と、第１下側コーナー部形成部８２と、第２下側コーナー部形成部８３とを含む。また、下型８０は、型合わせ部８４と、被取付部６０に相当する第１板部７１を受ける座部８５とを含む。
上型９０は、それぞれキャビティＣの内面の一部を形成する、上底部形成部９１と、第１脚部形成部９２と、第２脚部形成部９３と、第１上側コーナー部形成部９４と、第２上側コーナー部形成部９５とを含む。また、上型９０は、型締め状態で下型８０の型合わせ部８４と当接される型合わせ部９６と、型締め状態で下型８０の座部８５との間で第１板部７１（被取付部６０）を挟持する挟持部９７とを含む。 Specifically, the lower mold 80 includes a lower bottom forming part 81, a first lower corner forming part 82, and a second lower corner forming part 83, each forming a part of the inner surface of the cavity C. including. The lower mold 80 includes a mold matching portion 84 and a seat portion 85 that receives the first plate portion 71 corresponding to the attached portion 60.
The upper die 90 forms a part of the inner surface of the cavity C, and forms an upper bottom part forming part 91, a first leg part forming part 92, a second leg part forming part 93, and a first upper corner part forming part 94. And a second upper corner portion forming portion 95. In addition, the upper die 90 includes a first plate portion 71 between a die matching portion 96 that contacts the die matching portion 84 of the lower die 80 in a clamped state and a seat portion 85 of the lower die 80 in a clamped state. (A mounting portion 60).

ここで、図６（ａ）〜（ｄ）は、かしめ工程中における第４板部７４の状態変化を示す概略図である。図６（ａ）〜（ｄ）においては、簡略化のため、シールド電線２０とスリーブ４０との図示を省略してある。図６（ａ）に示される、かしめ前の状態から、図６（ｂ）に示すように、上型９０が少し下降した初期段階では、第４板部７４が、上型９０の第１脚部形成部９２と第２脚部形成部９３によって下側へ押圧され、且つ、第４板部７４が上下に長い楕円状に変形され、且つ、第４板部７４の先端部７４ｂが、第３板部７３の途中部に当接される。   Here, FIGS. 6A to 6D are schematic diagrams showing a state change of the fourth plate portion 74 during the caulking process. 6A to 6D, illustration of the shielded electric wire 20 and the sleeve 40 is omitted for simplification. In an initial stage in which the upper die 90 is slightly lowered from the state before the caulking shown in FIG. 6A, as shown in FIG. 6B, the fourth plate portion 74 is connected to the first leg of the upper die 90. The lower portion is pressed downward by the portion forming portion 92 and the second leg portion forming portion 93, and the fourth plate portion 74 is deformed into a vertically long elliptical shape, and the tip portion 74b of the fourth plate portion 74 is It is brought into contact with the middle part of the three-plate part 73.

次いで、上型９０がさらに下降することにより、図６（ｃ）に示すように、第４板部７４に、第１脚部５３に近似した形状の第１直線状部７４ｃと、第２脚部５４に近似した形状の第２直線状部７４ｄと、第１直線状部７４ｃと第２直線状部７４ｄとの間の湾曲凸部形状の頂部７４ｅと、先端部７４ｂを支点として第１直線状部に対して折り曲げられた折り曲げ状部７４ｆとが形成される。   Then, as the upper die 90 further descends, as shown in FIG. 6C, the fourth plate portion 74 includes a first linear portion 74c having a shape similar to the first leg portion 53, and a second leg portion. A second straight portion 74d having a shape similar to the portion 54, a top portion 74e having a curved convex shape between the first straight portion 74c and the second straight portion 74d, and a first straight line having the tip portion 74b as a fulcrum. A bent portion 74f bent with respect to the shape portion is formed.

次いで、図６（ｄ）及び図５（ｂ）に示すように、上型９０が型締め状態まで下降することにより、上底部５１と、下底部５２と、第１脚部５３と、第２脚部５４と、第１上側コーナー部５５と、第２上側コーナー部５６と、第１下側コーナー部５７と、第２下側コーナー部５８とが形成される。また、基端部７４ａに相当する巻回始端５０ｓから所定範囲の部分である重合外側部分ＯＬ１が、先端部７４ｂに相当する巻回終端５０ｅから所定範囲の部分である重合内側部分ＯＬ２の外側に重合されて重合領域ＯＬが形成される。   Next, as shown in FIGS. 6D and 5B, the upper die 90 is lowered to the clamped state, so that the upper bottom portion 51, the lower bottom portion 52, the first leg portion 53, and the second A leg 54, a first upper corner 55, a second upper corner 56, a first lower corner 57, and a second lower corner 58 are formed. In addition, the overlapping outer portion OL1 that is a portion within a predetermined range from the winding start end 50s corresponding to the base end portion 74a is outside the overlapping inner portion OL2 that is a portion within a predetermined range from the winding end 50e corresponding to the distal end portion 74b. The polymerization is performed to form a polymerization region OL.

上型９０の上底部形成部９１が、かしめ工程の最終段階で上底部５１を形成するときに、上底部５１を介して、折り曲げ状部７４ｆに相当する重合内側部分ＯＬ２を重合外側部分ＯＬ１側へ強く押圧することができる。このため、重合領域ＯＬを高いかしめ荷重で強くかしめることが可能となる。
また、かしめ工程の最終段階で、第１上側コーナー部５５と第２上側コーナー部５６が形成されるため、かしめ工程の途中において、巻回終端５０ｅの巻き方向Ｒへの変位が阻害されることがない。このため、巻き方向Ｒに関して所要の長さの重合領域ＯＬを得ることができる。 When the upper bottom forming section 91 of the upper die 90 forms the upper bottom 51 in the final stage of the caulking process, the overlapping inner portion OL2 corresponding to the bent portion 74f is connected via the upper bottom 51 to the overlapping outer portion OL1. Can be pressed strongly. For this reason, it is possible to strongly caulk the overlap region OL with a high caulking load.
Further, since the first upper corner portion 55 and the second upper corner portion 56 are formed at the final stage of the caulking process, the displacement of the winding end 50e in the winding direction R is hindered during the caulking process. There is no. For this reason, it is possible to obtain the overlap region OL having a required length in the winding direction R.

また、かしめ時において、シールド電線２０の中心部材２４が、中心部材２４の周囲の複数の被覆電線２１が偏ったり、捩じれたりすることを抑制する機能を果たす。なお、図３及び図５（ｂ）では、中心部材２４の図示を省略してある。
本実施形態では、巻回始端５０ｓから巻回終端５０ｅまで所定の巻き方向Ｒに一回りを超えて巻回されたかしめ固定部５０が、重合領域ＯＬを形成する状態でシールド電線２０にかしめ固定される。重合領域ＯＬによって、かしめ固定部５０の開きが抑制されるため、かしめ保持力を高くすることができる。 Further, at the time of caulking, the central member 24 of the shielded electric wire 20 has a function of preventing the plurality of covered electric wires 21 around the central member 24 from being biased or twisted. 3 and 5B, the illustration of the center member 24 is omitted.
In the present embodiment, the caulking fixing portion 50 wound more than one turn in the predetermined winding direction R from the winding start end 50 s to the winding end 50 e is caulked and fixed to the shielded electric wire 20 in a state where the overlap region OL is formed. Is done. Since the opening of the caulking fixing portion 50 is suppressed by the overlap region OL, the caulking holding force can be increased.

また、被取付部６０が、巻回始端５０ｓと直接、接続されており、かしめ固定部５０と被取付部６０とは、シールド電線２０の長手方向Ｘに関する位置が重なっている。このため、シールド電線２０の長手方向Ｘに関して、保持金具３０の小型化を通じて、接続構造１０の小型化を達成することができる。
また、シールド電線２０の長手方向Ｘに沿って見て、かしめ固定部５０が、重合領域ＯＬに配置されたコーナー部である第１下側コーナー部５７を含む多角形形状に形成さている。重合領域ＯＬに配置された第１下側コーナー部５７では、重合内側部分ＯＬ２の開きが重合外側部分ＯＬ１によって抑制される。このため、かしめ保持力を向上することができる。 Further, the attached portion 60 is directly connected to the winding start end 50 s, and the caulking fixing portion 50 and the attached portion 60 overlap at positions in the longitudinal direction X of the shielded wire 20. For this reason, in the longitudinal direction X of the shielded electric wire 20, it is possible to achieve the miniaturization of the connection structure 10 through the miniaturization of the holding bracket 30.
Further, when viewed along the longitudinal direction X of the shielded electric wire 20, the caulking fixing portion 50 is formed in a polygonal shape including a first lower corner portion 57 which is a corner portion arranged in the overlap region OL. In the first lower corner portion 57 disposed in the overlap region OL, the opening of the overlap inside portion OL2 is suppressed by the overlap outside portion OL1. For this reason, the caulking holding force can be improved.

また、巻回始端５０ｓから巻回終端５０ｅまで一回りを超えて巻回されたかしめ固定部５０の重合領域ＯＬが、内側のスリーブ４０にかしめ固定されることで、三重に重合される。このため、スプリングバックによるかしめ固定部５０の開きを抑制して、かしめ保持力を高くすることができる。
また、外側のかしめ固定部５０と内側のスリーブ４０とが互いに相似の多角形形状を形成する状態で、外側のかしめ固定部５０の締付力と内側のスリーブ４０の反発力を拮抗させて、スプリングバックによる、かしめ固定部５０の開きを確実に抑制することができる。 Further, the overlap region OL of the swaged fixing portion 50 that is wound more than one turn from the winding start end 50s to the winding end 50e is swaged and fixed to the inner sleeve 40, so that the stacking is performed three times. Therefore, it is possible to suppress the opening of the caulking fixing portion 50 due to the springback, and to increase the caulking holding force.
Further, in a state where the outer caulking fixing portion 50 and the inner sleeve 40 form a similar polygonal shape, the tightening force of the outer caulking fixing portion 50 and the repulsive force of the inner sleeve 40 are antagonized, Opening of the caulking fixing portion 50 due to springback can be reliably suppressed.

また、かしめ固定部５０とスリーブ４０との対応するコーナー部どうし（第１上側コーナー部５５，４５。第２上側コーナー部５６，４６。第１下側コーナー部５７，４７。第２下側コーナー部５８，４８。）のかしめ固定によって、スプリングバックによる、かしめ固定部５０の開きを確実に抑制することができる。
特に、かしめ固定部５０の重合領域ＯＬの第１下側コーナー部５７が、スリーブ４０の第１下側コーナー部４７にかしめ固定されるので、スプリングバックによる、かしめ固定部５０の開きを確実に抑制することができる。 Corresponding corner portions of the caulking fixing portion 50 and the sleeve 40 (first upper corner portions 55, 45; second upper corner portions 56, 46; first lower corner portions 57, 47; second lower corner). By caulking and fixing the portions 58 and 48, the opening of the caulking fixing portion 50 due to springback can be reliably suppressed.
In particular, since the first lower corner portion 57 of the overlap region OL of the caulking fixing portion 50 is caulked and fixed to the first lower corner portion 47 of the sleeve 40, the opening of the caulking fixing portion 50 by springback is reliably performed. Can be suppressed.

また、かしめ固定部５０が、巻回始端５０ｓから巻回終端５０ｅまで一回りを超えて巻回された状態で台形形状を形成しており、下底部５２と第１脚部５３との間の第１下側コーナー部５７に配置された巻回始端５０ｓから所定範囲の部分が重合外側部分ＯＬ１とされ、下底部５２の途中部５２Ｐに配置された巻回終端５０ｅから所定範囲の部分が重合内側部分ＯＬ２とされて、重合外側部分ＯＬ１と重合内側部分ＯＬ２とが互いに重合された重合領域ＯＬを形成している。このため、かしめ固定部５０のスプリングバックによって、第１脚部５３が、上端を中心として下端側を開こうとする開き力Ｆ（図３参照）が、第１下側コーナー部５７において、重合内側部分ＯＬ２を重合外側部分ＯＬ１に押圧干渉させる方向に働く。このため、かしめ保持力を高くすることができる。
（第２実施形態）
図７は、本発明の第２実施形態に係る、電線と保持金具との接続構造１０Ｐの概略平面図である。図７の第２実施形態が、図１（ｂ）の第１実施形態と異なるのは、接続構造１０Ｐでは、保持金具３０Ｐにおいて、被取付部６０が、かしめ固定部５０の巻回始端５０ｓに対して平板状の介在部６２を介して接続されていることである。介在部６２は、巻回始端５０ｓに沿ってシールド電線２０の長手方向Ｘに延びる接続縁６２ａを介して巻回始端５０ｓと接続されている。また、かしめ固定部５０の一部と被取付部６０の一部とは、シールド電線２０の長手方向Ｘの位置が重なっている。 Further, the caulking fixing portion 50 forms a trapezoidal shape in a state of being wound more than one turn from the winding start end 50s to the winding end 50e, and is formed between the lower bottom portion 52 and the first leg portion 53. A portion within a predetermined range from the winding start end 50s arranged at the first lower corner portion 57 is an overlapping outside portion OL1, and a portion within a predetermined range from the winding end 50e arranged at the middle portion 52P of the lower bottom portion 52 is overlapping. The inner portion OL2 forms an overlap region OL in which the overlap outer portion OL1 and overlap inner portion OL2 are overlapped with each other. Therefore, due to the springback of the caulking fixing portion 50, the opening force F (see FIG. 3) of the first leg portion 53 to open the lower end side around the upper end is overlapped at the first lower corner portion 57. The inner portion OL2 acts in a direction to cause interference with the overlapping outer portion OL1 by pressing. For this reason, the swaging holding force can be increased.
(2nd Embodiment)
FIG. 7 is a schematic plan view of a connection structure 10P between an electric wire and a holding fitting according to a second embodiment of the present invention. The second embodiment of FIG. 7 is different from the first embodiment of FIG. 1 (b) in the connection structure 10P, in the holding bracket 30P, the mounted portion 60 is located at the winding start end 50s of the caulking fixing portion 50. On the other hand, it is connected via a flat plate-shaped interposition part 62. The interposition part 62 is connected to the winding start end 50s via a connection edge 62a extending in the longitudinal direction X of the shielded electric wire 20 along the winding start end 50s. In addition, a part of the caulking fixing part 50 and a part of the attached part 60 overlap with each other in the longitudinal direction X of the shielded electric wire 20.

介在部６２は、かしめ固定部５０の下底部５２（図７では示さず）に対して平行である。介在部６２と被取付部６０とは、面一に形成されている。矩形状をなす被取付部６０は、矩形状をなす介在部６２に対して階段状に接続されている。
本実施形態では、第１実施形態と同じく、重合領域ＯＬ（図７では示さず）が形成されたかしめ固定部５０の開きが抑制されることにより、かしめ保持力を向上することができる。また、かしめ固定部５０の一部と被取付部６０の一部とが、シールド電線２０の長手方向Ｘに位置を重ねて配置されるので、小型化を達成しつつ、取付対象に対する取付の自由度を向上することができる。
（第３実施形態）
図８は、本発明の第３実施形態に係る、電線と保持金具との接続構造１０Ｑの概略斜視図である。 The interposition part 62 is parallel to the lower bottom part 52 (not shown in FIG. 7) of the caulking fixing part 50. The interposed portion 62 and the mounted portion 60 are formed flush. The mounting portion 60 having a rectangular shape is connected to the intervening portion 62 having a rectangular shape in a stepwise manner.
In the present embodiment, similarly to the first embodiment, the swaging holding force can be improved by suppressing the opening of the swaging fixing portion 50 in which the overlap region OL (not shown in FIG. 7) is formed. In addition, since a part of the caulking fixing part 50 and a part of the part to be mounted 60 are arranged so as to overlap in the longitudinal direction X of the shielded electric wire 20, the size of the shielded wire 20 can be reduced and the mounting of the shielded wire 20 can be freely performed. The degree can be improved.
(Third embodiment)
FIG. 8 is a schematic perspective view of a connection structure 10Q between an electric wire and a holding fitting according to a third embodiment of the present invention.

図８の第３実施形態が、図１（ｂ）の第１実施形態と異なるのは、接続構造１０Ｑでは、保持金具３０Ｑにおいて、被取付部６０が、かしめ固定部５０の巻回始端５０ｓに対してアングル状の介在部６３を介して接続されていることである。
介在部６３は、平板状の第１板部６４と、平板状の第２板部６５とを含む。第１板部６４は、かしめ固定部５０の巻回始端５０ｓに沿ってシールド電線２０の長手方向Ｘに延びる第１接続縁６６を介して巻回始端５０ｓと接続されている。 The third embodiment shown in FIG. 8 differs from the first embodiment shown in FIG. 1B in that, in the connection structure 10Q, in the holding bracket 30Q, the mounted portion 60 is provided at the winding start end 50s of the caulking fixing portion 50. In other words, it is connected via an angle-shaped interposed portion 63.
The interposition portion 63 includes a first plate portion 64 having a flat plate shape and a second plate portion 65 having a flat plate shape. The first plate portion 64 is connected to the winding start end 50s via a first connection edge 66 extending in the longitudinal direction X of the shielded electric wire 20 along the winding start end 50s of the caulking fixing portion 50.

図９は、保持金具３０Ｑの要部の別角度からの一部破断斜視図である。図８及び図９に示すように、第２板部６５は、第２接続縁６７を介して第１板部６４と交差状に接続されている。図９に示すように、第１板部６４と第２板部６５とが形成する交差角度である第１交差角度θ１は、例えば直角である。第１接続縁６６と第２接続縁６７とは、互いに平行である。   FIG. 9 is a partially cutaway perspective view of a main part of the holding metal fitting 30Q from another angle. As shown in FIGS. 8 and 9, the second plate portion 65 is connected to the first plate portion 64 via the second connection edge 67 in an intersecting manner. As shown in FIG. 9, the first intersection angle θ1, which is the intersection angle formed by the first plate portion 64 and the second plate portion 65, is, for example, a right angle. The first connection edge 66 and the second connection edge 67 are parallel to each other.

第２板部６５は、第３接続縁６８を介して被取付部６０と交差状に接続されている。第２接続縁６７と第３接続縁６８とは、互いに傾斜している。第３接続縁６８を介して第２板部６５と被取付部６０とが形成する交差角度である第２交差角度θ２は、鈍角とされている。
図８に示すように、被取付部６０は、シールド電線２０の長手方向Ｘに対して傾斜されている。また、かしめ固定部５０の一部と被取付部６０の一部とは、シールド電線２０の長手方向Ｘの位置が重なるように配置されている。 The second plate portion 65 is connected to the mounted portion 60 in an intersecting manner via the third connection edge 68. The second connection edge 67 and the third connection edge 68 are inclined with respect to each other. The second intersection angle θ2, which is the intersection angle formed between the second plate portion 65 and the attached portion 60 via the third connection edge 68, is an obtuse angle.
As shown in FIG. 8, the mounted portion 60 is inclined with respect to the longitudinal direction X of the shielded electric wire 20. Further, a part of the caulking fixing part 50 and a part of the attached part 60 are arranged such that the positions in the longitudinal direction X of the shielded electric wire 20 overlap.

なお、各接続縁６６〜６８は、保持金具３０Ｑが板金材料で形成されるため、所定の曲げＲを有している。また、第１接続縁６６と第２接続縁６７とは、互いに傾斜していてもよい。また、第２接続縁６７と第３接続縁６８とは、互いに平行であってもよい。また、第１交差角度θ１は、鈍角や鋭角であってもよい。また、第２交差角度θ２は、直角や鋭角であってもよい。また、被取付部６０は、折り返し重合された重合板で形成されていてもよい。   Each of the connection edges 66 to 68 has a predetermined bend R because the holding fitting 30Q is formed of a sheet metal material. Further, the first connection edge 66 and the second connection edge 67 may be inclined with respect to each other. Further, the second connection edge 67 and the third connection edge 68 may be parallel to each other. Further, the first intersection angle θ1 may be an obtuse angle or an acute angle. Further, the second intersection angle θ2 may be a right angle or an acute angle. Further, the attached portion 60 may be formed of a polymerized board that is folded and polymerized.

本実施形態では、第１実施形態と同じく、重合領域ＯＬが形成されたかしめ固定部５０の開きが抑制されることにより、かしめ保持力を向上することができる。また、かしめ固定部５０の一部と被取付部６０の一部とが、シールド電線２０の長手方向Ｘに位置を重ねて配置されるので、小型化を達成しつつ、取付対象に対する取付の自由度を向上することができる。   In the present embodiment, as in the first embodiment, the swaging holding force can be improved by suppressing the swaging of the swaging fixing portion 50 in which the overlap region OL is formed. In addition, since a part of the caulking fixing part 50 and a part of the part to be mounted 60 are arranged so as to overlap in the longitudinal direction X of the shielded electric wire 20, the size of the shielded wire 20 can be reduced and the mounting of the shielded wire 20 can be freely performed. The degree can be improved.
