しかしながら、基底部の長手方向（シールド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。接続部の配置位置に制限があるため、取付対象に対する取付の自由度が低い。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、かしめ保持力が高く、且つ取付対象に対する取付自由度が高い、シールド電線と端子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 shielded wire), it is necessary to arrange the connection portion at a position separated from the pair of crimping pieces. Since there is a restriction on the arrangement position of the connection part, the degree of freedom of attachment to the attachment object is low. In addition, the arm portion is wound only around a part of the outer circumference of the sheath, and the crimping holding force is weak.
SUMMARY OF THE INVENTION An object of the present invention is to provide a connection structure between a shielded wire and a terminal fitting, which has a high crimping holding force and a high degree of mounting freedom with respect to an object to be mounted.

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。 Although alphanumeric characters in parentheses represent corresponding components and the like in embodiments described later, this does not mean that the present invention should be limited to those embodiments. The same shall apply hereinafter in this section.

請求項２に記載の発明のように、前記かしめ固定部と前記スリーブとが、互いに対向する複数の湾曲状のコーナー部であって、前記下側コーナー部を含む複数の湾曲状のコーナー部（５５，４５；５６，４６；５７，４７；５８，４８）を含んでいてもよい。 As in the invention according to claim 2, the crimped fixing portion and the sleeve are a plurality of curved corner portions facing each other, and a plurality of curved corner portions including the lower corner portion ( 55,45; 56,46; 57,47; 58,48) .

請求項１に記載の発明では、巻回始端から巻回終端まで一回りを超えて巻回されたかしめ固定部の重合領域が、内側のスリーブ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、取付対象に取り付けるための被取付部が、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いる。このため、シールド電線の長手方向に関して、かしめ固定部と被取付部とを任意の位置関係に設定することができ、取付の自由度を高くすることができる。 In the invention according to claim 1, the overlapping region of the crimped fixing portion wound more than one turn from the winding start end to the winding end is crimped and fixed to the inner sleeve, so that it is triple overlapped. . For this reason, it is possible to suppress the opening of the crimped fixing portion due to springback and increase the crimping holding force.
Moreover, the to-be-attached part for attaching to an attachment object is connected indirectly via the winding starting end directly or through an intervening part. Therefore, it is possible to set an arbitrary positional relationship between the crimped fixing portion and the attached portion with respect to the longitudinal direction of the shielded wire, thereby increasing the degree of freedom in attachment.

また、外側のかしめ固定部と内側のスリーブ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の締付力と内側のスリーブの反発力を拮抗させて、スプリングバックによる、かしめ固定部の開きを確実に抑制することができる。また、かしめ固定部において、底部の途中部に配置された巻回終端から所定範囲の部分である重合内側部分の外側に、下側コーナー部に配置された券回始端から所定範囲の部分が重合外側部分が、重合されて、互いに重合されるので、スプリングバックによる、かしめ固定部の開きを確実に抑制することができる。
請求項２に記載の発明では、前記かしめ固定部と前記スリーブとのコーナー部どうしのかしめ固定によって、スプリングバックによる、かしめ固定部の開きを確実に抑制することができる。 In addition , in a state in which the outer crimped fixing portion and the inner sleeve form polygonal shapes similar to each other, the tightening force of the outer crimped fixing portion and the repulsive force of the inner sleeve are counterbalanced, It is possible to reliably suppress the opening of the crimped fixing portion. In addition, in the crimped fixing portion, a predetermined range from the winding start end disposed at the lower corner portion is superimposed on the outside of the overlapping inner portion, which is a portion within a predetermined range from the winding end disposed in the middle of the bottom portion. Since the outer portions are overlapped and overlapped with each other, it is possible to reliably suppress the opening of the crimped fixing portion due to springback.
According to the second aspect of the present invention, by caulking and fixing the corner portions of the caulking fixing portion and the sleeve, it is possible to reliably suppress the opening of the caulking fixing portion due to springback.

次いで、図４（ｅ）及び（ｆ）にされる端子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を包囲するように端子金具素材７０を装着する。
具体的には、端子金具素材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。 4(e) and 4(f), the terminal metal material 70 is mounted so as to surround the folded portion 22a in the longitudinal direction X of the shielded wire 20. As shown in FIG.
Specifically, the terminal metal fitting material 70 includes a flat plate-like first plate portion 71 corresponding to the attached portion 60 and an arc plate-like second plate portion 72 corresponding to the outer portion of the first lower corner portion 57 . , a flat plate-like third plate portion 73 corresponding to the outer portion of the lower bottom portion 52 , and an arc plate-like fourth plate portion 74 .

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端子金具素材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 tip end portion 74b that is close to the inside of the second plate portion 72 with a gap therebetween and forms a winding end portion 50e. including. The shield wire 20 is inserted into the insertion space S formed by the flat third plate portion 73 and the arc plate-shaped fourth plate portion 74 .
Next, in the crimping process shown in FIGS. 5A and 5B, the terminal metal fitting material 70 with the shielded wire 20 inserted therein is placed on the lower mold 80 of the crimping mold 100, after which the crimping mold 100 is placed. By lowering the upper mold 90, the inner surface of the cavity C formed between the lower mold 80 and the upper mold 90 crimps into 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。

The lower die 80 also includes a die matching portion 84 and a seat portion 85 that receives the first plate portion 71 corresponding to the attached portion 60 .
The upper mold 90 includes an upper bottom portion forming portion 91, a first leg portion forming portion 92, a second leg portion forming portion 93, and a first upper corner portion forming portion 94, which form part of the inner surface of the cavity C, respectively. and a second upper corner forming portion 95 . In addition, the upper die 90 is positioned between the die-matching portion 96 that contacts the die-matching portion 84 of the lower die 80 in the die-closed state and the seat portion 85 of the lower die 80 in the die-closed state. and a sandwiching portion 97 that sandwiches (mounted 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 changes in the state of the fourth plate portion 74 during the caulking process. 6A to 6D, illustration of the shield wire 20 and the sleeve 40 is omitted for simplification. From the state before crimping shown in FIG. 6( a ), as shown in FIG. The fourth plate portion 74 is pressed downward by the portion forming portion 92 and the second leg portion forming portion 93, the fourth plate portion 74 is deformed into an elliptical shape elongated vertically, and the distal end portion 74b of the fourth plate portion 74 It abuts on the middle portion of the third plate portion 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。 Next, as the upper die 90 is further lowered, as shown in FIG. A second linear portion 74d having a shape similar to that of the portion 54, an apex portion 74e having a curved convex shape between the first linear portion 74c and the second linear portion 74d, and a first straight line having a tip portion 74b as a fulcrum. A bent shape portion 74f that is 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. 6(d) and 5(b), the upper mold 90 is lowered to the clamped state, thereby forming the upper bottom portion 51, the lower bottom portion 52, the first leg portion 53, and the second A leg portion 54, a first upper corner portion 55, a second upper corner portion 56, a first lower corner portion 57, and a second lower corner portion 58 are formed. Further, the overlapped outer portion OL1, which is a portion within a predetermined range from the winding start end 50s corresponding to the base end portion 74a, is outside the overlapped inner portion OL2, which is a portion within a predetermined range from the winding end 50e corresponding to the tip portion 74b. It is polymerized to form a polymerized 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 base portion forming portion 91 of the upper die 90 forms the upper base portion 51 in the final stage of the crimping process, the upper base portion 51 is placed on the overlapping inner portion OL2 corresponding to the bent portion 74f to the overlapping outer portion OL1 side. can be pressed hard. Therefore, it is possible to strongly crimp the overlapping region OL with a high crimping load.
Further, since the first upper corner portion 55 and the second upper corner portion 56 are formed in the final stage of the crimping process, displacement of the winding end 50e in the winding direction R during the crimping process is prevented. There is no Therefore, it is possible to obtain the overlapping region OL having a required length with respect to 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。 Further, during crimping, the central member 24 of the shielded wire 20 functions to prevent the plurality of covered wires 21 around the central member 24 from being biased or twisted. 3 and 5B, illustration of the central member 24 is omitted.
In the present embodiment, the overlapping region OL of the crimping fixing portion 50, which is wound more than once from the winding start end 50s to the winding end 50e, is crimped to the inner sleeve 40 to be triple overlapped. be. Therefore, it is possible to suppress the opening of the crimped fixing portion 50 due to springback and increase the crimped holding force.

また、かしめ固定部５０が一方向（所定の巻き方向Ｒ）に巻回される構造である。このため、取付対象に取り付けるための被取付部６０を、巻回始端５０ｓと直接、接続することが可能である。また、後述する図７に示す第２実施形態や図８に示す第３実施形態のように、被取付部６０を、巻回始端５０ｓに対して介在部６２，６３を介して間接的に接続することも可能である。すなわち、シールド電線２０の長手方向Ｘに関して、かしめ固定部５０と被取付部６０とを任意の位置関係に設定することができ、取付の自由度を高くすることができる。 In addition, the structure is such that the crimped fixing portion 50 is wound in one direction (predetermined winding direction R). Therefore, it is possible to directly connect the attached portion 60 to be attached to the attachment target to the winding start end 50s. Further, as in a second embodiment shown in FIG. 7 and a third embodiment shown in FIG. 8, which will be described later, the attached portion 60 is indirectly connected to the winding start end 50s via intervening portions 62 and 63. It is also possible to That is, the caulking fixing portion 50 and the attached portion 60 can be set to any positional relationship with respect to the longitudinal direction X of the shielded wire 20, and the degree of freedom in attachment can be increased.

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。
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。 In addition, in a state in which the outer crimped fixing portion 50 and the inner sleeve 40 form mutually similar polygonal shapes, the tightening force of the outer crimped fixing portion 50 and the repulsive force of the inner sleeve 40 are counterbalanced, It is possible to reliably suppress the opening of the crimped fixing portion 50 due to springback.
Corresponding corner portions of the crimped fixing portion 50 and the sleeve 40 (first upper corner portions 55 and 45; second upper corner portions 56 and 46; first lower corner portions 57 and 47; 58, 48.), it is possible to reliably suppress the opening of the crimped fixing portion 50 due to springback.

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。
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、シールド電線と端子金具との接続構造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、端子金具３０Ｐにおいて、被取付部６０が、かしめ固定部５０の巻回始端５０ｓから平板状の介在部６２を介して接続されていることである。介在部６２は、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。 In particular, since the first lower corner portion 57 of the overlapping region OL of the crimped fixing portion 50 is crimped and fixed to the first lower corner portion 47 of the sleeve 40, the opening of the crimped fixing portion 50 due to springback is ensured. can be suppressed.
In addition, the crimped fixing portion 50 forms a trapezoidal shape in a state in which it is wound more than once from the winding start end 50s to the winding end 50e. A portion within a predetermined range from the winding start end 50s arranged at the first lower corner portion 57 is the overlapped outer 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 overlapped. As an inner part OL2, the polymerized outer part OL1 and the polymerized inner part OL2 form an overlapped region OL. Therefore, the opening force F (see FIG. 3) that causes the first leg portion 53 to open the lower end side around the upper end due to the springback of the crimped fixing portion 50 is superimposed at the first lower corner portion 57. It works in the direction of pressing and interfering the inner portion OL2 with the overlapping outer portion OL1. Therefore, it is possible to increase the crimping holding force.
