Description

シールド編組線の接続構造およびシールドコネクタShield braided wire connection structure and shield connector
　本発明は、シールド編組線の接続構造およびシールドコネクタに係り、特に、筒状のものによってシールド編組線を保持するものに関する。 The present invention relates to a shield braided wire connection structure and a shield connector, and more particularly, to a shield braided wire held by a cylindrical one.
　第１従来例として、図８に示すような、シールドターミナル３０３とスリーブ３０５とを用いてシールド編組線３０７を固定しているシールド編組線の接続構造３０１が知られている（特許文献１参照）。 As a first conventional example, a shield braided wire connection structure 301 in which a shield braided wire 307 is fixed using a shield terminal 303 and a sleeve 305 as shown in FIG. 8 is known (see Patent Document 1). .
　図８に示す第１従来例のシールド編組線の接続構造３０１を生成するためには、まず、図９（ａ）で示すように、シールド電線３０９の一端部で、外部被覆体３１１を除去して、シールド編組線３０７を露出させ、さらに、シールド編組線３０７と内部被覆体３１３とを除去して芯線３１５を露出させる。 In order to generate the shield braided wire connection structure 301 of the first conventional example shown in FIG. 8, first, the outer covering 311 is removed at one end of the shielded wire 309 as shown in FIG. 9A. Thus, the shield braided wire 307 is exposed, and the shield braided wire 307 and the inner covering 313 are removed to expose the core wire 315.
　続いて、図９（ｂ）で示すように、スリーブ３０５を内部被覆体３１３に嵌めるとともに、シールド編組線３０７を外部被覆体３１１側に寄せる。 Subsequently, as shown in FIG. 9B, the sleeve 305 is fitted into the inner covering 313 and the shield braided wire 307 is moved toward the outer covering 311 side.
　続いて、外部被覆体３１１側に寄せられたシールド編組線３０７を折り返してスリーブ３０５に被せ、さらに、スリーブ３０５に被せられたシールド編組線３０７にシールドターミナル３０３を被せた後、シールドターミナル３０３を圧着して、シールドターミナル３０３とシールド編組線３０７とスリーブ３０５とを内部被覆体３１３に固定している。 Subsequently, the shield braided wire 307 brought close to the outer covering 311 side is folded back and covered with the sleeve 305. Further, after the shield braided wire 307 covered with the sleeve 305 is covered with the shield terminal 303, the shield terminal 303 is crimped. Thus, the shield terminal 303, the shield braided wire 307, and the sleeve 305 are fixed to the inner covering 313.
　また、第２従来例として、図１０、１１に示すように、接続部材３５３とシールド筒３５５とを用いてシールド編組線３５７を接続しているシールド編組線の接続構造３５１が知られている（特許文献２参照）。 As a second conventional example, a shield braided wire connection structure 351 in which a shield braided wire 357 is connected using a connecting member 353 and a shield tube 355 is known as shown in FIGS. Patent Document 2).
　図１０、１１に示す第２従来例のシールド編組線の接続構造３５１では、接続部材３５３に一対の押さえ片３６７を設け、この押さえ片３６７のテコ作用と押さえ受け部３６９とによってシールド編組線３５７を挟み込み固定している。 In the shield braided wire connection structure 351 of the second conventional example shown in FIGS. 10 and 11, a pair of pressing pieces 367 are provided on the connection member 353, and the shield braided wire 357 is formed by the lever action of the pressing pieces 367 and the pressing receiving portion 369. Is sandwiched and fixed.
　なお、図１０、１１に示す参照符号３５９で示すものは、シールド電線３６１の外部被覆体であり、参照符号３６３で示すものは、シールド電線３６１の内部被覆体であり、参照符号３６５で示すものは、シールド電線３６１の芯線である。 10 and 11, the reference numeral 359 is an outer covering of the shielded electric wire 361, and the reference numeral 363 is an inner covering of the shielded electric wire 361, which is indicated by the reference numeral 365.

　第１従来例のシールド編組線の接続構造３０１では、スリーブ３０５を圧着することで、シールド編組線３０７を固定している。このため、シールド編組線の接続構造を容易には得ることができないという問題がある。 In the shield braided wire connection structure 301 of the first conventional example, the shield braided wire 307 is fixed by crimping the sleeve 305. For this reason, there exists a problem that the connection structure of a shield braided wire cannot be obtained easily.
　すなわち、圧着前の準備工程として、シールド編組線３０７の余剰部分を除去して、シールド編組線３０７の折り返しをするので、作業工数が増えてしまう。また、スリーブ３０５を圧着するには、プレス機やアプリケータ（圧着歯型）の設備が必要になり、設備費が発生してしまう。さらに、シールド編組線の接続構造の態様が異なると、圧着に要する圧着力（必要トン数）も変わるものであるが、プレス機で圧着しようとしても、プレス機の能力で必要トン数を発生することができない場合があり、この場合には別途新規な設備が必要になってしまう。 That is, as a preparatory step before crimping, the surplus portion of the shield braided wire 307 is removed and the shield braided wire 307 is folded back, which increases the number of work steps. In addition, in order to crimp the sleeve 305, equipment for a press machine and an applicator (crimping tooth mold) is required, resulting in equipment costs. Furthermore, if the connection structure of the shield braided wire is different, the crimping force (necessary tonnage) required for crimping also changes. In this case, new equipment is required separately.
　また、第２従来例のシールド編組線の接続構造３５１では、圧着をおこなっていないのでプレス機等の設備は不要であるが、テコの作用でシールド編組線３５７を保持している。このため、シールド編組線をスリーブによる圧着で保持している場合と異なり、シールド電線３６１の触れや引張り等によって、接続部材３５３が外れてしまうおそれがあるという問題がある。 Also, in the shield braided wire connection structure 351 of the second conventional example, no crimping is performed, and thus no equipment such as a press machine is required, but the shield braided wire 357 is held by the action of leverage. For this reason, unlike the case where the shield braided wire is held by crimping with a sleeve, there is a problem that the connecting member 353 may be detached due to touching or pulling of the shielded electric wire 361.
　本発明は、上記問題点に鑑みてなされたものであり、シールド編組線がはずれにくいシールド編組線の接続構造を容易に得ることを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to easily obtain a shield braided wire connection structure in which a shield braided wire is difficult to come off.

The shield braided wire inserted into the cylindrical portion and the shield braided wire are formed in a cylindrical shape, and the outer periphery is in contact with the inner periphery of the shield braided wire so that the shield braided wire is sandwiched in cooperation with the outer cylindrical portion. And an inserted sleeve. In order to prevent the shield braided wire from slipping out of the outer tube portion, at least one of the outer tube portion and the sleeve is tapered, and the sleeve is formed from one end side in the longitudinal direction of the shield braided wire. The inside of the.
　外筒部が、テーパ状になっており、スリーブは、一定の外径を有する大径部と、大径部よりも小さい一定の外径を有する小径部とを備え、大径部が、外筒部と協働してシールド編組線を挟み込んでいる構成であってもよい。 The outer cylinder portion is tapered, and the sleeve includes a large diameter portion having a constant outer diameter and a small diameter portion having a constant outer diameter smaller than the large diameter portion. The structure which pinched | interposed the shield braided wire in cooperation with the cylinder part may be sufficient.
　スリーブには、シールド編組線の一端部を収容するシールド編組線収容部が設けられていてもよい。 The sleeve may be provided with a shield braided wire accommodating portion that accommodates one end of the shield braided wire.
　本発明の第２の態様に係るシールドコネクタは、上述のシールド編組線収容部が設けられているシールド編組線の接続構造を有するシールドコネクタであって、ハウジングを備え、シールド編組線は、シールド電線のシールド編組線であり、外筒部は、ハウジングに設置されているシールドターミナルの外筒部であり、シールド電線の長手方向の一端部は、内部被覆体が露出している状態でハウジング内に挿入されており、シールド電線の内部被覆体が露出している部位にシール材が設けられており、スリーブのシールド編組線収容部が、シール材の位置決めをしている構成である。 A shield connector according to a second aspect of the present invention is a shield connector having a shield braided wire connection structure provided with the above-described shield braided wire receiving portion, and includes a housing, and the shield braided wire is a shielded electric wire. Shield braided wire, the outer cylinder part is the outer cylinder part of the shield terminal installed in the housing, and one end part of the shield wire in the longitudinal direction is inside the housing with the inner covering exposed. The sealing material is provided in a portion where the inner covering of the shielded electric wire is exposed, and the shield braided wire receiving portion of the sleeve is positioned in the sealing material.

　［第１実施形態］
　第１実施形態に係るシールド編組線の接続構造１は、たとえば、シールドコネクタ３に適用されるものである。 [First Embodiment]
The shield braided wire connection structure 1 according to the first embodiment is applied to, for example, a shield connector 3.
　シールド編組線の接続構造１を有するシールドコネクタ３は、図１、２で示すように、樹脂等の非導電性材料で構成されたハウジング５と、金属等の導電性材料で構成されたシールドターミナル７と、ゴム等の非導電性の弾性材料で構成されたシール材９とを備える。 As shown in FIGS. 1 and 2, a shield connector 3 having a shield braided wire connection structure 1 includes a housing 5 made of a non-conductive material such as resin, and a shield terminal made of a conductive material such as metal. 7 and a sealing material 9 made of a non-conductive elastic material such as rubber.
　ここで、説明の便宜のために、シールド電線１１の延伸方向（長手方向）を前後方向とし、前後方向に対して直交する所定の一方向を横方向とし、前後方向と横方向とに対して直交する所定の一方向を縦方向とする。 Here, for convenience of explanation, the extending direction (longitudinal direction) of the shielded electric wire 11 is the front-rear direction, the predetermined one direction orthogonal to the front-rear direction is the lateral direction, and the front-rear direction and the lateral direction are A predetermined one direction orthogonal to each other is defined as a vertical direction.
　シールドコネクタ３には、シールド電線１１の一端部（前端部）が一体的に設置される。シールド電線１１が設置されたシールドコネクタ３は、接続相手の筐体１３に一体的に設置される。 The shield connector 3 is integrally provided with one end (front end) of the shielded electric wire 11. The shield connector 3 on which the shielded electric wires 11 are installed is integrally installed on the connection partner casing 13.
　シールド電線１１の前端側の部位は、ハウジング５内に挿入されている。シールド電線１１とハウジング５との間に設けられたシール材９が、シールド電線１１の後側からハウジング内に水等が入ることを防いでいる。 The part of the shield wire 11 on the front end side is inserted into the housing 5. A sealing material 9 provided between the shielded electric wire 11 and the housing 5 prevents water or the like from entering the housing from the rear side of the shielded electric wire 11.
　シールド電線１１の前端には、端子金具１５が設置されている。端子金具１５は、接続相手の筐体１３内に設けられている端子（図示せず）に電気的に接続される。 A terminal fitting 15 is installed at the front end of the shielded electric wire 11. The terminal fitting 15 is electrically connected to a terminal (not shown) provided in the housing 13 to be connected.
　シールドターミナル７は、たとえば、板状の素材を適宜変形した形態である殻状（厚さが一定な立体形状）に形成されており、ハウジング５の後側でハウジング５を覆うようにしてハウジング５に一体的に設置されている。 The shield terminal 7 is formed in, for example, a shell shape (three-dimensional shape having a constant thickness) that is a shape obtained by appropriately deforming a plate-like material, and covers the housing 5 on the rear side of the housing 5. It is installed in one.
　シールド電線１１は、シールドターミナル７の一部である外筒部１７を貫通して、後側に延伸している。 The shielded electric wire 11 passes through the outer cylinder portion 17 which is a part of the shield terminal 7 and extends rearward.
　シールド編組線の接続構造１についてさらに詳しく説明する。シールド編組線の接続構造１は、筒状（たとえば円筒状）に形成された外筒部１７と、シールド電線１１のシールド編組線１９と、筒状（たとえば円筒状）に形成されたスリーブ２１とを備える。 Shield braided wire connection structure 1 will be described in more detail. The shield braided wire connection structure 1 includes an outer tube portion 17 formed in a cylindrical shape (for example, a cylindrical shape), a shield braided wire 19 for the shielded electric wire 11, and a sleeve 21 formed in a cylindrical shape (for example, a cylindrical shape). Is provided.
　シールド電線１１のシールド編組線１９は、同軸ケーブルの外側導体のように、金属等の導電性材料で構成された複数本の素線を編むことで、筒状（たとえば円筒状）に形成されている。 The shield braided wire 19 of the shielded electric wire 11 is formed in a cylindrical shape (for example, a cylindrical shape) by knitting a plurality of strands made of a conductive material such as metal, like the outer conductor of a coaxial cable. Yes.
　シールド編組線１９の前後方向の前端側の部位が、外筒部１７の内部に挿入されている。シールド編組線１９は、前後方向の前側の部位の外周が、外筒部１７の内周に接している。 A portion of the shield braided wire 19 on the front end side in the front-rear direction is inserted into the outer cylinder portion 17. In the shield braided wire 19, the outer periphery of the front side portion in the front-rear direction is in contact with the inner periphery of the outer cylinder portion 17.
　スリーブ２１は、たとえば金属等の導電性材料で筒状（たとえば円筒状）に形成されており、シールド編組線１９および外筒部１７の内部に挿入されている。そして、スリーブ２１の外周がシールド編組線１９の内周に接することで、スリーブ２１が外筒部１７と協働してシールド編組線１９を挟み込み、シールド編組線１９を外筒部１７に固定している。 The sleeve 21 is formed in a cylindrical shape (for example, a cylindrical shape) from a conductive material such as metal, and is inserted into the shield braided wire 19 and the outer cylindrical portion 17. Then, since the outer periphery of the sleeve 21 is in contact with the inner periphery of the shield braided wire 19, the sleeve 21 cooperates with the outer tube portion 17 to sandwich the shield braided wire 19, and the shield braided wire 19 is fixed to the outer tube portion 17. ing.
　外筒部１７に対しシールド編組線１９が後側に移動し外筒部１７から抜けて離れてしまうことを防止するために、外筒部１７とスリーブ２１の少なくとも一方がテーパ状になっている。すなわち、外筒部１７とスリーブ２１との少なくとも一方の径が、シールド編組線１９の長手方向で一端（前）側から他端（後）側に向かうにしたがって次第に小さくなっている。 In order to prevent the shield braided wire 19 from moving to the rear side with respect to the outer tube portion 17 and coming off from the outer tube portion 17, at least one of the outer tube portion 17 and the sleeve 21 is tapered. . That is, the diameter of at least one of the outer cylinder portion 17 and the sleeve 21 gradually decreases in the longitudinal direction of the shield braided wire 19 from one end (front) side to the other end (rear) side.
　シールド編組線１９の長手方向の一端側（前端側）からは、スリーブ２１が外筒部１７の内側に入り込んでいる。そして、シールド編組線１９が、外筒部１７よりも後側の箇所（図２におけるシールド電線１１の右端）で、後側（図２の右方向）への引っ張られたときに、スリーブ２１が外筒部１７とシールド編組線１９とに食い込むように構成されている。 From one end side (front end side) of the shield braided wire 19 in the longitudinal direction, the sleeve 21 enters the inside of the outer cylindrical portion 17. When the shield braided wire 19 is pulled rearward (the right end of the shielded electric wire 11 in FIG. 2) from the outer cylinder portion 17 toward the rear (rightward in FIG. 2), the sleeve 21 is It is configured to bite into the outer tube portion 17 and the shield braided wire 19.
　さらに具体的に説明すると、第１実施形態では、外筒部１７の内径が、テーパ状になっている（図２の左から右に向かうにしたがって縮径している）。 More specifically, in the first embodiment, the inner diameter of the outer cylinder portion 17 is tapered (the diameter is reduced from the left to the right in FIG. 2).
　スリーブ２１は、一定の外径の大径部２３と、一定の外径の小径部２５とを備える。小径部２５の外径の値は、大径部２３の外径の値よりも小さくなっている。小径部２５は、シールド編組線１９の前後方向で大径部２３よりも後側に位置している。 The sleeve 21 includes a large-diameter portion 23 having a constant outer diameter and a small-diameter portion 25 having a constant outer diameter. The value of the outer diameter of the small diameter portion 25 is smaller than the value of the outer diameter of the large diameter portion 23. The small diameter portion 25 is located behind the large diameter portion 23 in the front-rear direction of the shield braided wire 19.
　スリーブ２１は、シールド編組線１９の内側に入り込んでいる。そして、大径部２３が、外筒部１７と協働してシールド編組線１９を挟み込んでいる。 The sleeve 21 enters the inside of the shield braided wire 19. The large-diameter portion 23 sandwiches the shield braided wire 19 in cooperation with the outer tube portion 17.
　小径部２５は、シールド電線１１の屈曲や振れを抑制するために設けられている。 The small-diameter portion 25 is provided in order to suppress bending and vibration of the shielded electric wire 11.
　筒状のシールド編組線１９の中心軸は、前後方向に延伸している。シールド編組線１９の中心軸と、外筒部１７の中心軸と、スリーブ２１の中心軸とはお互いに一致している。 The central axis of the cylindrical shield braided wire 19 extends in the front-rear direction. The central axis of the shield braided wire 19, the central axis of the outer tube portion 17, and the central axis of the sleeve 21 coincide with each other.
　外筒部１７は、たとえば、肉厚が一定なテーパ状である円筒状に形成されており、外筒部１７の内面（内径、外径）は、中心軸の延伸方向の一端（前端）から他端（後端）に向かうにしたがって次第に小さくなっている。 The outer cylinder part 17 is formed in, for example, a cylindrical shape having a constant thickness, and the inner surface (inner diameter, outer diameter) of the outer cylinder part 17 extends from one end (front end) in the extending direction of the central axis. It becomes gradually smaller toward the other end (rear end).
　シールド編組線１９は、たとえば、円筒状に形成されているが、導電性材料の複数本の素線を編むことで構成されていることで、その外径と内径とは、適宜拡張可能となっている。すなわち、シールド電線１１から外部被覆体２７を除去しただけの原始の状態では、シールド編組線１９の外径は、外筒部１７の内径よりも小さい。しかし、外筒部１７に挿入された状態のシールド編組線１９の前端側の部位では、たとえば、スリーブ２１によりシールド編組線１９の外径（内径）が大きくなっており、シールド編組線１９が外筒部１７の円錐台側面形状（テーパ状）の内面に接触している（図４、５（ａ）参照）。 The shield braided wire 19 is formed, for example, in a cylindrical shape, but the outer diameter and the inner diameter of the shield braided wire 19 can be appropriately expanded by knitting a plurality of strands of conductive material. ing. That is, the outer diameter of the shield braided wire 19 is smaller than the inner diameter of the outer cylinder portion 17 in the primitive state where the outer covering 27 is removed from the shielded electric wire 11. However, the outer diameter (inner diameter) of the shield braided wire 19 is increased by, for example, the sleeve 21 at the front end portion of the shield braided wire 19 inserted into the outer cylinder portion 17, and the shield braided wire 19 is outside. It contacts the inner surface of the truncated cone side surface shape (tapered shape) of the cylindrical portion 17 (see FIGS. 4 and 5A).
　スリーブ２１は、たとえば、円筒状の素材を塑性加工することで形成されており、大径部２３の中心軸と小径部２５の中心軸とは互いに一致している。大径部２３と小径部２５とは、中心軸の延伸方向の一端（前端）から他端（後端）に向かいこの順にならんでいる。 The sleeve 21 is formed, for example, by plastic processing of a cylindrical material, and the central axis of the large diameter portion 23 and the central axis of the small diameter portion 25 coincide with each other. The large diameter portion 23 and the small diameter portion 25 are arranged in this order from one end (front end) in the extending direction of the central axis to the other end (rear end).
　大径部２３の内外径は一定の値になっており、小径部の内外径も一定の値になっている。大径部２３の外径の値は、テーパ状の外筒部１７の内径の最大径（図５（ａ）の左端の内径）から所定の値（シールド編組線１９を構成している素線の直径の２倍の値、すなわち、筒状のシールド編組線１９の筒の厚さの値）を引いた値よりも小さくなっている。また、大径部２３の外径の値は、テーパ状の外筒部１７の内径の最小径（図５（ａ）の右端の内径）から所定の値（シールド編組線１９を構成している素線の直径の２倍の値）を引いた値よりも大きくなっている。 The inner and outer diameters of the large diameter portion 23 are constant values, and the inner and outer diameters of the small diameter portions are also constant values. The value of the outer diameter of the large-diameter portion 23 is a predetermined value (the wire constituting the shield braided wire 19) from the maximum inner diameter of the tapered outer cylinder portion 17 (the inner diameter at the left end in FIG. 5A). Is smaller than the value obtained by subtracting the value twice the diameter of the cylinder, that is, the value of the cylinder thickness of the cylindrical shield braided wire 19. Further, the value of the outer diameter of the large diameter portion 23 constitutes a predetermined value (shield braided wire 19) from the minimum inner diameter of the tapered outer cylinder portion 17 (the inner diameter at the right end in FIG. 5A). It is larger than the value obtained by subtracting the value twice the diameter of the strand.
　小径部２５の筒の肉厚は、大径部２３の筒の肉厚と等しくなっている。小径部２５の外径の値は、大径部２３の外径の値よりも小さく、大径部２３の内径の値と同程度か僅かに小さくなっている。また、小径部２５の内径の値は、原始の状態におけるシールド編組線１９の内径の値（シールド電線１１の内部被覆体２９の外径の値）よりもわずかに大きくなっている。 The wall thickness of the cylinder of the small diameter part 25 is equal to the wall thickness of the cylinder of the large diameter part 23. The value of the outer diameter of the small diameter portion 25 is smaller than the value of the outer diameter of the large diameter portion 23, and is the same as or slightly smaller than the value of the inner diameter of the large diameter portion 23. The value of the inner diameter of the small diameter portion 25 is slightly larger than the value of the inner diameter of the shield braided wire 19 in the original state (the value of the outer diameter of the inner covering 29 of the shielded electric wire 11).
　これにより、シールド電線１１が屈曲しもしくは振れようとしても、小径部２５の内周にシールド電線１１の内部被覆体２９の外周が当接し、シールド電線１１の屈曲や振れが抑制されるようになっている。 Thereby, even if the shielded electric wire 11 is bent or shaken, the outer periphery of the inner covering 29 of the shielded electric wire 11 comes into contact with the inner circumference of the small diameter portion 25, and the bent or shaken of the shielded electric wire 11 is suppressed. ing.
　シールド電線１１は、金属等の導電性材料で構成された芯線３１と、合成樹脂等の絶縁性の材料で構成され芯線３１を覆っている内部被覆体２９と、内部被覆体２９を覆っているシールド編組線１９と、合成樹脂等の絶縁性の材料で構成されシールド編組線１９を覆っている外部被覆体２７とを備える。 The shielded electric wire 11 covers a core wire 31 made of a conductive material such as a metal, an inner covering 29 made of an insulating material such as a synthetic resin and covering the core wire 31, and the inner covering 29. A shield braided wire 19 and an outer covering 27 that is made of an insulating material such as a synthetic resin and covers the shield braided wire 19 are provided.
　シールド電線１１の断面（長手方向に対して直交する平面による断面）は、芯線３１がほぼ円形状に配置されており、内部被覆体２９の外周が、芯線３１と同軸の円形状（直径が芯線３１の直径よりも大きい円形状）になっており、シールド編組線１９の外周が、芯線３１と同軸の円形状（直径が内部被覆体２９の外径よりも大きい円形状）になっており、外部被覆体２７の外周が、芯線３１と同軸の円形状（直径がシールド編組線１９の外径よりも大きい円形状）になっている。 In the cross section of the shielded electric wire 11 (cross section by a plane orthogonal to the longitudinal direction), the core wire 31 is arranged in a substantially circular shape, and the outer periphery of the inner covering 29 is a circular shape (the diameter of the core wire is coaxial with the core wire 31). The outer circumference of the shield braided wire 19 is a circular shape coaxial with the core wire 31 (a circular shape having a diameter larger than the outer diameter of the inner covering body 29), The outer periphery of the outer covering body 27 has a circular shape coaxial with the core wire 31 (a circular shape whose diameter is larger than the outer diameter of the shield braided wire 19).
　図２で示すように、シールド電線１１の長手方向の一端（前端）Ｐ０から第１の所定の寸法だけ他端側（後側）に離れているシールド電線１１の部位を第１の部位Ｐ１とし、シールド電線１１の長手方向の一端から第２の所定の寸法だけ他端側に離れているシールド電線１１の部位を第２の部位Ｐ２とし、シールド電線１１の長手方向の一端から第３の所定の寸法だけ他端側に離れているシールド電線１１の部位を第３の部位Ｐ３とする。 As shown in FIG. 2, the part of the shielded electric wire 11 that is separated from the one end (front end) P0 in the longitudinal direction of the shielded electric wire 11 to the other end side (rear side) by the first predetermined dimension is defined as the first part P1. The part of the shielded electric wire 11 that is separated from the one end in the longitudinal direction of the shielded electric wire 11 to the other end side by the second predetermined dimension is defined as the second part P2, and the third predetermined predetermined value from one end in the longitudinal direction of the shielded electric wire 11 A portion of the shielded electric wire 11 that is separated to the other end side by the dimension is defined as a third portion P3.
　ここで、第１の所定の寸法の値、第２の所定の寸法の値、第３の所定の寸法の値の関係は、「第１の所定の寸法の値＜第２の所定の寸法の値＜第３の所定の寸法の値」になっている。 Here, the relationship between the value of the first predetermined dimension, the value of the second predetermined dimension, and the value of the third predetermined dimension is “the value of the first predetermined dimension <the value of the second predetermined dimension. Value <value of third predetermined dimension ”.
　シールド電線１１では、長手方向の一端Ｐ０と第１の部位Ｐ１との間で、外部被覆体２７とシールド編組線１９と内部被覆体２９とが除去されて芯線３１が露出している。第１の部位Ｐ１と第２の部位Ｐ２の間で、外部被覆体２７とシールド編組線１９とが除去されて内部被覆体２９が露出している。第２の部位Ｐ２と第３の部位Ｐ３の間で、外部被覆体２７が除去されてシールド編組線１９が露出している。第３の部位Ｐ３よりも他端側（後側）では、シールド電線１１が、なにも除去されていない初期の状態で存在している。 In the shielded electric wire 11, the outer covering 27, the shield braided wire 19, and the inner covering 29 are removed between the longitudinal end P <b> 0 and the first part P <b> 1 to expose the core 31. Between the first part P1 and the second part P2, the outer covering 27 and the shield braided wire 19 are removed, and the inner covering 29 is exposed. Between the second part P2 and the third part P3, the outer covering 27 is removed, and the shield braided wire 19 is exposed. On the other end side (rear side) with respect to the third portion P3, the shielded electric wire 11 exists in an initial state where nothing is removed.
　シールド編組線１９が、スリーブ２１によって外筒部１７に固定されている状態について詳しく説明する。 The state where the shield braided wire 19 is fixed to the outer cylinder portion 17 by the sleeve 21 will be described in detail.
　シールド電線１１の長手方向（前後方向）では、シールド電線１１の第２の部位Ｐ２と第３の部位Ｐ３との間で露出しているシールド編組線１９の内外径が、前側（図２の左側）で原始状態よりも大きくなっている。 In the longitudinal direction (front-rear direction) of the shielded electric wire 11, the inner and outer diameters of the shield braided wire 19 exposed between the second part P2 and the third part P3 of the shielded electric wire 11 are the front side (left side in FIG. 2). ) Is larger than the original state.
　この内外径が大きくなっているシールド編組線１９の部位のうちの一部の部位（長手方向の中間の所定の長さの部位）が、外筒部１７の内径に接触している。 A part of the shield braided wire 19 having a large inner and outer diameter (a part having a predetermined length in the middle in the longitudinal direction) is in contact with the inner diameter of the outer cylinder part 17.
　スリーブ２１は、大径部２３がシールド電線１１の前側に位置し、小径部２５がシールド電線１１の後側に位置して、外筒部１７の内径に接触しているシールド編組線１９に係合している。 The sleeve 21 has a large-diameter portion 23 located on the front side of the shielded electric wire 11 and a small-diameter portion 25 located on the rear side of the shielded electric wire 11, and is associated with the shield braided wire 19 that is in contact with the inner diameter of the outer cylindrical portion 17. Match.
　さらに説明すると、スリーブ２１は、シールド電線１１の後側に押されて、外筒部１７の内径に接触しているシールド編組線１９内に、前から後に向かう方向で挿入されている（図３の矢印を参照）。これにより、大径部２３の端部（小径部２５側の端部、円形状の部位）が、シールド編組線１９を押圧している。そして、スリーブ２１が外筒部１７と協同して、シールド編組線１９を付勢した状態で挟み込んでいる。これにより、シールド編組線１９とスリーブ２１とが、外筒部１７に一体的に設けられている。 More specifically, the sleeve 21 is pushed to the rear side of the shielded electric wire 11 and inserted in the shield braided wire 19 in contact with the inner diameter of the outer cylinder portion 17 in the direction from the front to the rear (FIG. 3). (See arrow for.) As a result, the end of the large-diameter portion 23 (the end on the small-diameter portion 25 side, a circular portion) presses the shield braided wire 19. The sleeve 21 is sandwiched in cooperation with the outer cylinder portion 17 in a state where the shield braided wire 19 is urged. Thereby, the shield braided wire 19 and the sleeve 21 are integrally provided in the outer cylinder part 17.
　このような状態で、シールド電線１１およびシールド編組線１９が後側に引っ張られると（図４の矢印Ａ１参照）、スリーブ２１とシールド編組線１９との間の摩擦力で、スリーブ２１がシールド電線１１の後側に移動しようとする。そして、いわゆるクサビ効果と同様の効果によってスリーブ２１と外筒部１７とがさらに強い力でシールド編組線１９を挟み込み（図４の矢印Ａ２参照）、スリーブ２１とシールド編組線１９との間の摩擦力と、シールド編組線１９と外筒部１７との間の摩擦力とで、シールド電線１１が、外筒部１７から長手方向他端側（後側）に抜け出ないようになっている。 When the shielded electric wire 11 and the shield braided wire 19 are pulled rearward in this state (see arrow A1 in FIG. 4), the sleeve 21 is shielded by the frictional force between the sleeve 21 and the shield braided wire 19. 11 will try to move to the rear side. The sleeve 21 and the outer cylindrical portion 17 sandwich the shield braided wire 19 with a stronger force by the same effect as the so-called wedge effect (see arrow A2 in FIG. 4), and the friction between the sleeve 21 and the shield braided wire 19 Due to the force and the frictional force between the shield braided wire 19 and the outer cylinder part 17, the shielded electric wire 11 is prevented from coming out from the outer cylinder part 17 to the other end side (rear side) in the longitudinal direction.
　なお、スリーブ２１の大径部２３の前端（小径部２５とは反対側の端）は、シールド電線１１の長手方向で、外筒部１７の前端から前方に突出しているが、シールド電線１１の第２の部位Ｐ２までは届いていない。 The front end of the large-diameter portion 23 of the sleeve 21 (the end opposite to the small-diameter portion 25) protrudes forward from the front end of the outer cylinder portion 17 in the longitudinal direction of the shielded electric wire 11. It has not reached the second site P2.
　また、スリーブ２１の小径部２５の後端（大径部２３とは反対側の端）は、シールド電線１１の長手方向で、外筒部１７の後端から後方に突出しているが、シールド電線１１の第３の部位Ｐ３までは届いていない。さらに、スリーブ２１の小径部２５の後端は、シールド電線１１のシールド編組線１９に接触して、シールド編組線１９の内外径を拡張している。 Further, the rear end (the end opposite to the large diameter portion 23) of the small diameter portion 25 of the sleeve 21 protrudes rearward from the rear end of the outer tube portion 17 in the longitudinal direction of the shield electric wire 11, but the shield electric wire The eleventh third portion P3 has not been reached. Furthermore, the rear end of the small-diameter portion 25 of the sleeve 21 is in contact with the shield braided wire 19 of the shielded electric wire 11 to expand the inner and outer diameters of the shield braided wire 19.
　次に、シールドコネクタ３についてさらに詳しく説明する。 Next, the shield connector 3 will be described in more detail.
　シールドコネクタ３のハウジング５は、円筒状のハウジング本体部３３と、フランジ部３５とを備える。ハウジング本体部３３の内側の空間３７には、シール材設置部３９と端子設置部４１とが形成されている。 The housing 5 of the shield connector 3 includes a cylindrical housing main body portion 33 and a flange portion 35. In the space 37 inside the housing body 33, a seal material installation part 39 and a terminal installation part 41 are formed.
　シール材設置部３９は、円筒状に形成されており、ハウジング本体部３３の後側に設けられている。端子設置部４１は、ハウジング本体部３３の前側に設けられている。ハウジング本体部３３やシール材設置部３９は、シールド電線１１と同軸になっている。シール材設置部３９の内径は、内部被覆体２９やスリーブ２１の外径よりも大きく、シール材９の外径よりも僅かに小さくなっている。シール材設置部３９の底面（端子設置部４１との境界に接する面）４３は、シール材９が当接する平面（前後方向に対して直交する平面）になっている。 The seal material installation part 39 is formed in a cylindrical shape and is provided on the rear side of the housing main body part 33. The terminal installation portion 41 is provided on the front side of the housing main body portion 33. The housing body 33 and the seal material installation part 39 are coaxial with the shielded electric wire 11. The inner diameter of the sealing material installation portion 39 is larger than the outer diameter of the inner covering 29 and the sleeve 21 and slightly smaller than the outer diameter of the sealing material 9. A bottom surface (a surface in contact with the boundary with the terminal installation portion 41) 43 of the sealing material installation portion 39 is a flat surface (a plane orthogonal to the front-rear direction) with which the sealing material 9 abuts.
　フランジ部３５は、前後方向の中間部でハウジング本体部３３の外周から外側に突出している。また、フランジ部３５は、一部の部位の突出量が他の部位の突出量よりも大きくなっている。この突出量が大きくなっている箇所に、金属製のブッシュ４５が一体的に設けられている。 The flange portion 35 protrudes outward from the outer periphery of the housing main body portion 33 at an intermediate portion in the front-rear direction. Further, in the flange portion 35, the protruding amount of some parts is larger than the protruding amount of other parts. A metal bush 45 is integrally provided at a location where the protruding amount is large.
　フランジ部３５の前面は、前後方向に対して直交している平面になっており、ハウジング５（シールドコネクタ３）を接続相手の筐体１３に設置した状態では、フランジ部３５の前面が接続相手の筐体に接触している。また、ハウジング５（シールドコネクタ３）を接続相手の筐体１３に設置した状態では、ブッシュ４５にボルト（図示せず）が挿入され、このボルトの雄ネジが接続相手の筐体１３の雌ネジ（図示せず）に螺号している。 The front surface of the flange portion 35 is a plane orthogonal to the front-rear direction. When the housing 5 (shield connector 3) is installed in the housing 13 to be connected, the front surface of the flange portion 35 is the connection counterpart. In contact with the housing. Further, in a state where the housing 5 (shield connector 3) is installed in the connection partner housing 13, a bolt (not shown) is inserted into the bush 45, and the male screw of this bolt is the female screw of the connection partner housing 13. (Not shown).
　ハウジング本体部３３の前側の部位（フランジ部３５よりも前側の部位）の外周には、パッキン（たとえばＯリング）４７が設けられており、接続相手の筐体１３内に水等が入り込むことを防止している。 A packing (for example, an O-ring) 47 is provided on the outer periphery of the front portion of the housing main body 33 (the front portion of the flange portion 35), so that water or the like enters the casing 13 to be connected. It is preventing.
　シールドターミナル７は、フランジ部３５の側面（外周面）と、フランジ部３５の後側の面と、ハウジング本体部３３の後側の部位（フランジ部３５よりも後側の部位）とを覆うようにして、ハウジング５に一体的に設けられている。シールドターミナル７の外筒部１７が、ハウジング本体部３３から後方に突出している。 The shield terminal 7 covers the side surface (outer peripheral surface) of the flange portion 35, the rear surface of the flange portion 35, and the rear portion of the housing body portion 33 (the rear portion of the flange portion 35). Thus, it is provided integrally with the housing 5. The outer cylinder portion 17 of the shield terminal 7 protrudes rearward from the housing main body portion 33.
　シールド電線１１の芯線３１の前端部には、端子金具１５が一体的に設けられている。そして、シールド電線１１がシールドコネクタ３に設置された状態では、ハウジング本体部３３の前端部に設けられている端子係止部（たとえば弾性を備えた係止爪）４９が、端子金具１５に設けられた端子被係止部（たとえば、貫通孔）５１の係合し、端子金具１５がハウジング５と一体化している。 A terminal fitting 15 is integrally provided at the front end of the core wire 31 of the shielded electric wire 11. In a state where the shielded electric wire 11 is installed on the shield connector 3, a terminal locking portion (for example, a locking claw having elasticity) 49 provided at the front end portion of the housing main body portion 33 is provided on the terminal fitting 15. The terminal locking portion (for example, through hole) 51 thus engaged is engaged, and the terminal fitting 15 is integrated with the housing 5.
　シールド電線１１は、次に示す態様でシールドコネクタ３に設置されている。 The shielded electric wire 11 is installed on the shield connector 3 in the following manner.
　端子金具１５は、前側の部位がシールドコネクタ３の前端から前方に突出しており、芯線３１に係合している後側の部位が、端子設置部４１内に位置している。シールド電線１１の第１の部位Ｐ１は、シール材設置部３９の底面４３よりも、ごく僅かに前方に位置しており、第２の部位Ｐ２は、ハウジング本体部３３よりも、ごく僅かに前方に位置しており、第３の部位Ｐ３は、外筒部１７よりも後方に位置している。 The front part of the terminal fitting 15 protrudes forward from the front end of the shield connector 3, and the rear part engaged with the core wire 31 is located in the terminal installation part 41. The first part P1 of the shielded electric wire 11 is located slightly in front of the bottom surface 43 of the seal material installation part 39, and the second part P2 is slightly in front of the housing body 33. The third part P <b> 3 is located behind the outer cylinder part 17.
　シール材９は、前端が底面４３に接触しており、内周が、シールド電線１１の内部被覆体２９に接触している。なお、非設置の状態では、シール材９の内径が内部被覆体２９の外径よりもごく僅かに小さくなっている。これにより、シールドコネクタ３に設置された状態では、シール材９が内部被覆体２９を付勢している。同様にして、シール材９の外周は、シール材設置部３９の内周面を付勢してシール材設置部３９の内周面に接触している。これにより、ハウジング５の端子設置部４１内に水等が入り込むことを防止している。 The front end of the sealing material 9 is in contact with the bottom surface 43, and the inner periphery is in contact with the inner covering 29 of the shielded electric wire 11. In the non-installed state, the inner diameter of the sealing material 9 is very slightly smaller than the outer diameter of the inner covering body 29. Thereby, in the state installed in the shield connector 3, the sealing material 9 biases the inner covering 29. Similarly, the outer periphery of the sealing material 9 is in contact with the inner peripheral surface of the sealing material installation portion 39 by urging the inner peripheral surface of the sealing material installation portion 39. This prevents water and the like from entering the terminal installation portion 41 of the housing 5.
　また、環状のリヤホルダ５３の前面がシール材９の後面に接触することで、シール材９が、ハウジング５に固定されている。なお、リヤホルダ５３はたとえば、シール材設置部３９内に圧入されていることで、ハウジング５に固定されている。また、リヤホルダ５３の後端は、第２の部位Ｐ２よりも、ごく僅かに前方に位置している。 Further, the seal material 9 is fixed to the housing 5 by the front surface of the annular rear holder 53 coming into contact with the rear surface of the seal material 9. The rear holder 53 is fixed to the housing 5 by being press-fitted into the seal material installation part 39, for example. Further, the rear end of the rear holder 53 is located slightly forward of the second portion P2.
　次に、シールド電線１１のシールドコネクタ３への設置手順について説明する。 Next, the installation procedure of the shielded electric wire 11 to the shield connector 3 will be described.
　まず、シールド電線１１の前端部で、外部被覆体２７、シールド編組線１９、内部被覆体２９を適宜除去し、シールド電線１１を図２で示す状態にする。 First, at the front end of the shielded electric wire 11, the outer covering 27, the shield braided wire 19, and the inner covering 29 are appropriately removed, and the shielded electric wire 11 is brought into the state shown in FIG.
　続いて、シールド編組線１９の前端が外筒部１７よりも若干前方に位置するようにして、外筒部１７にシールド電線１１の一端部を通す。 Subsequently, one end portion of the shielded electric wire 11 is passed through the outer tube portion 17 so that the front end of the shield braided wire 19 is positioned slightly forward of the outer tube portion 17.
　続いて、スリーブ２１にシールド電線１１を通し、スリーブ２１を後方に移動する（図３参照）。そして、スリーブ２１と外筒部１７とで、シールド編組線１９を挟み込んで固定する（図４参照）。 Subsequently, the shield wire 11 is passed through the sleeve 21, and the sleeve 21 is moved backward (see FIG. 3). Then, the shield braided wire 19 is sandwiched and fixed between the sleeve 21 and the outer cylinder portion 17 (see FIG. 4).
　続いて、端子金具１５を芯線３１に設置し、端子金具１５とシールド電線１１とシールドターミナル７とスリーブ２１とを、接続相手の筐体１３に設置されているハウジング５に設置する。 Subsequently, the terminal fitting 15 is installed on the core wire 31, and the terminal fitting 15, the shielded electric wire 11, the shield terminal 7, and the sleeve 21 are installed in the housing 5 installed in the casing 13 to be connected.
　シールド編組線の接続構造１によれば、テーパ状になっている外筒部１７とスリーブ２１とによってシールド編組線１９を保持するように構成されている。このため、圧着作業が不要になり、シールド編組線の接続構造１を容易に得ることができる。また、スリーブ２１が、シールド編組線１９の長手方向の前側から、後側で縮径しているテーパ状の外筒部１７の内側に入り込んでいる。このため、一旦保持されたシールド編組線１９がシールドターミナル７からはずれないようになっている。 According to the shield braided wire connection structure 1, the shield braided wire 19 is held by the tapered outer tube portion 17 and the sleeve 21. For this reason, a crimping operation is not required, and the shield braided wire connection structure 1 can be easily obtained. Further, the sleeve 21 enters the inside of the tapered outer cylinder portion 17 whose diameter is reduced on the rear side from the front side in the longitudinal direction of the shield braided wire 19. For this reason, the shield braided wire 19 once held is prevented from coming off from the shield terminal 7.
　また、シールド編組線の接続構造１によれば、図９（ｂ）で示す第１従来例ようなシールド編組線の折り返しが不要である。このため、シールド編組線の接続構造１を得るための工数を削減することができる。 Further, according to the shield braided wire connection structure 1, the shield braided wire does not need to be folded back as in the first conventional example shown in FIG. 9B. For this reason, the man-hour for obtaining the connection structure 1 of a shield braided wire can be reduced.
　また、シールド編組線の接続構造１によれば、スリーブ２１の外周の円形状の全周と外筒部１７の内周の円形状の全周にて、シールド編組線１９を挟み固定することで、シールド編組線１９がシールドターミナル７にしっかりとバランス良く設置されている。このため、シールド編組線１９のほつれを無くすことができるとともに、シールド電線１１の屈曲をスリーブ２１で抑制することができる。 Further, according to the shield braided wire connection structure 1, the shield braided wire 19 is sandwiched and fixed between the entire circumference of the outer circumference of the sleeve 21 and the entire circumference of the inner circumference of the outer cylindrical portion 17. The shield braided wire 19 is firmly and well installed on the shield terminal 7. For this reason, fraying of the shield braided wire 19 can be eliminated, and bending of the shielded electric wire 11 can be suppressed by the sleeve 21.
　従来のシールド編組線の接続構造の一般的な構造では、シール材を保持するためのリヤホルダでシールド電線をガイドして押さえている。これに対して、第１実施形態に係るシールド編組線の接続構造１では、シール材９を保持するためだけにリヤホルダ５３を用いればよい。このため、リヤホルダ５３の前後方向の寸法を小さくすることができ、シールドコネクタ３を小型化することができる。 In the general structure of the conventional shield braided wire connection structure, the shield wire is guided and held by the rear holder for holding the sealing material. On the other hand, in the shield braided wire connection structure 1 according to the first embodiment, the rear holder 53 may be used only for holding the sealing material 9. For this reason, the dimension of the rear holder 53 in the front-rear direction can be reduced, and the shield connector 3 can be reduced in size.
　また、シールド編組線の接続構造１によれば、外筒部１７が後方に向かうにしたがって縮径したテーパ状となっており、スリーブ２１が外筒部１７の内側で前側から後側に向かって挿入されている。このため、シールド電線１１が後方に引っ張られても、シールド電線１１がシールドターミナル７やハウジング５から抜け出てしまうことが無くなる。 Further, according to the shield braided wire connection structure 1, the outer cylindrical portion 17 has a tapered shape with a diameter reduced toward the rear, and the sleeve 21 is located on the inner side of the outer cylindrical portion 17 from the front side toward the rear side. Has been inserted. For this reason, even if the shielded electric wire 11 is pulled backward, the shielded electric wire 11 does not come out of the shield terminal 7 or the housing 5.
　また、図８―１１に示す従来例の構造では、シールド編組線が折り返されて、二重になって内部被覆体を覆っている。これに対して、シールド編組線の接続構造１では、シールド編組線１９が折り返されておらず二重構造にはなっていない。このため、シールド編組線１９が必要以上に拡径されておらず、これにより、シールド性能の低下が抑制されている。 Also, in the structure of the conventional example shown in FIGS. 8-11, the shield braided wire is folded back to cover the inner covering in a doubled manner. On the other hand, in the shield braided wire connection structure 1, the shield braided wire 19 is not folded back and does not have a double structure. For this reason, the shield braided wire 19 is not expanded more than necessary, thereby suppressing a decrease in shield performance.
　また、シールド編組線の接続構造１によれば、小径部２５によってシールド電線１１の屈曲や振れが抑制されるので、ハウジング５等に対するシールド電線１１（内部被覆体２９）の偏りが抑制され、シール材９のシールド電線１１（内部被覆体２９）に対する片当たり抑制され、シール材９の偏磨耗等を抑制し耐久性を高めることができる。 Further, according to the shield braided wire connection structure 1, the small diameter portion 25 suppresses bending and vibration of the shielded electric wire 11, so that the bias of the shielded electric wire 11 (inner covering 29) with respect to the housing 5 and the like is suppressed, and the seal The contact of the material 9 with respect to the shielded electric wire 11 (inner covering body 29) is suppressed, and uneven wear and the like of the seal material 9 can be suppressed to increase durability.
　また、シールド編組線の接続構造１を、図５（ｂ）、５（ｃ）、６（ａ）―６（ｃ）で示すように適宜変形してもよい。なお、図５（ａ）は、図２で示すシールド編組線の接続構造１を模式的に示している。 Further, the shield braided wire connection structure 1 may be appropriately modified as shown in FIGS. 5 (b), 5 (c), and 6 (a) -6 (c). FIG. 5A schematically shows the shield braided wire connection structure 1 shown in FIG.
　図５（ｂ）、５（ｃ）で示すシールド編組線の接続構造１では、小径部２５をテーパ状にしてある。ただし、図５（ｂ）で示すシールド編組線の接続構造１では、大径部２３と小径部２５との間に段差が形成されている。一方、図５（ｃ）で示すシールド編組線の接続構造１では、大径部２３と小径部２５との間に段差が形成されていない。小径部２５をテーパ状にすることで、シールド編組線１９の内外径を拡大しやすくなり、スリーブ２１の設置が容易になる。 In the shield braided wire connection structure 1 shown in FIGS. 5B and 5C, the small diameter portion 25 is tapered. However, in the shield braided wire connection structure 1 shown in FIG. 5B, a step is formed between the large diameter portion 23 and the small diameter portion 25. On the other hand, in the shield braided wire connection structure 1 shown in FIG. 5C, no step is formed between the large diameter portion 23 and the small diameter portion 25. By making the small diameter portion 25 tapered, the inner and outer diameters of the shield braided wire 19 can be easily enlarged, and the sleeve 21 can be easily installed.
　図６（ａ）で示すシールド編組線の接続構造１では、スリーブ２１の前後方向の中間につば部２２を設けてあり、つば部２２と外筒部１７でシールド編組線１９を挟み込んでいる。図６（ｂ）で示すシールド編組線の接続構造１では、外筒部１７の径を一定にし、代わりに、スリーブ２１をテーパ状にしてある。図６（ｃ）で示すシールド編組線の接続構造１では、外筒部１７とスリーブ２１との両方をテーパ状にしてある。ただし、スリーブ２１の縮径率のほうが、外筒部１７の縮径率よりも大きくなっている。 In the shield braided wire connection structure 1 shown in FIG. 6 (a), a collar portion 22 is provided in the middle of the sleeve 21 in the front-rear direction, and the shield braided wire 19 is sandwiched between the collar portion 22 and the outer cylinder portion 17. In the shield braided wire connection structure 1 shown in FIG. 6B, the diameter of the outer cylindrical portion 17 is made constant, and the sleeve 21 is tapered instead. In the shield braided wire connection structure 1 shown in FIG. 6C, both the outer cylindrical portion 17 and the sleeve 21 are tapered. However, the diameter reduction rate of the sleeve 21 is larger than the diameter reduction rate of the outer cylindrical portion 17.
　さらに、シールド編組線の接続構造１において、スリーブ２１を一定の外径と一定の内径を備えた単なる円筒で構成してもよい。また、第１実施形態に係るシールド編組線の接続構造１では、外筒部１７と協働してシールド編組線１９を挟み込んでいるスリーブ２１の部位が小さな円弧状になっているが（Ｒ部が形成されているが）、Ｒ部を形成することなく、尖ったエッジ状にして、このエッジの部分が、シールド編組線１９に食い込むようにしてもよい。 Furthermore, in the shield braided wire connection structure 1, the sleeve 21 may be formed of a simple cylinder having a constant outer diameter and a constant inner diameter. Further, in the shield braided wire connection structure 1 according to the first embodiment, the portion of the sleeve 21 that sandwiches the shield braided wire 19 in cooperation with the outer cylinder portion 17 has a small arc shape (R portion). However, it is also possible to form a sharp edge without forming the R portion so that the edge portion bites into the shield braided wire 19.
　［第２実施形態］
　第２実施形態に係るシールド編組線の接続構造１ａも、図７で示すように、たとえば、シールドコネクタ３ａに適用される。 [Second Embodiment]
The shield braided wire connection structure 1a according to the second embodiment is also applied to, for example, the shield connector 3a as shown in FIG.
　第２実施形態に係るシールド編組線の接続構造１ａは、スリーブ２１ａに、シールド編組線１９の一端部（前端部）を収容するシールド編組線収容部５５が設けられている点が、第１実施形態に係るシールド編組線の接続構造１とは異なり、その他の点は、第１実施形態に係るシールド編組線の接続構造１と同様に構成され、同様の効果を奏する。ただし、シールドコネクタ３ａには、シール材９を保持するためのリヤホルダが設けられておらず、スリーブ２１ａのシールド編組線収容部５５が、リヤホルダに代わってシール材９を保持している。 The shield braided wire connecting structure 1a according to the second embodiment is that the sleeve 21a is provided with a shield braided wire accommodating portion 55 for accommodating one end (front end) of the shield braided wire 19 in the first implementation. Unlike the shield braided wire connection structure 1 according to the embodiment, other points are configured in the same manner as the shield braided wire connection structure 1 according to the first embodiment, and have the same effects. However, the shield connector 3a is not provided with a rear holder for holding the sealing material 9, and the shield braided wire accommodating portion 55 of the sleeve 21a holds the sealing material 9 instead of the rear holder.
　さらに詳しく説明すると、スリーブ２１ａは、大径部２３と小径部２５とに加えて、リング状部５７と折り返し部５９とを備える。リング状部５７は、中央部に円形状の貫通孔が形成された円板状に形成されている。すなわち、リング状部５７は、円板状の素材に、この素材の中心と中心が一致し径が素材の径よりも小さい貫通孔を設けた形状に形成されている。折り返し部５９は、内径が大径部の外径よりも大きな円筒状に形成されている。 More specifically, the sleeve 21 a includes a ring-shaped portion 57 and a folded portion 59 in addition to the large-diameter portion 23 and the small-diameter portion 25. The ring-shaped part 57 is formed in a disk shape in which a circular through hole is formed in the central part. That is, the ring-shaped part 57 is formed in a shape in which a disc-shaped material is provided with a through hole whose center matches the center of the material and whose diameter is smaller than the diameter of the material. The folded portion 59 is formed in a cylindrical shape whose inner diameter is larger than the outer diameter of the large diameter portion.
　スリーブ２１ａは、第１実施形態のスリーブ２１と同様にして、大径部２３および小径部２５とを備えているともに、たとえば、所定形状の材料を塑性加工等することで形成されている。大径部２３の肉厚と小径部２５の肉厚とリング状部５７の肉厚と折り返し部５９の肉厚とはお互いが等しくなっている。また、リング状部５７の中心軸と折り返し部５９の中心軸と大径部２３の中心軸とは、互いに一致している。 Similarly to the sleeve 21 of the first embodiment, the sleeve 21a includes a large-diameter portion 23 and a small-diameter portion 25, and is formed by plastic processing or the like of a material having a predetermined shape, for example. The thickness of the large-diameter portion 23, the thickness of the small-diameter portion 25, the thickness of the ring-shaped portion 57, and the thickness of the folded portion 59 are equal to each other. Further, the center axis of the ring-shaped portion 57, the center axis of the folded portion 59, and the center axis of the large-diameter portion 23 coincide with each other.
　リング状部５７の内径は、大径部２３の内径と等しくなっており、リング状部５７の外径は、折り返し部５９の外径と等しくなっている。 The inner diameter of the ring-shaped portion 57 is equal to the inner diameter of the large-diameter portion 23, and the outer diameter of the ring-shaped portion 57 is equal to the outer diameter of the folded portion 59.
　リング状部５７は、大径部２３の前端（小径部とは反対側の端）から、フランジ状になって大径部２３の径方向外側に展開している。折返し部５９は、リング状部５７の外周から小径部２５側（後側）に突出している。したがって、外側にリング状部５７が存在している大径部２３のところは、大径部２３と折り返し部５９との２重の円管状になっている。また、折り返し部５９の後端（リング状部５７とは反対側の端）は、前後方向（スリーブ２１ａの長手方向）で、大径部２３の後端よりも前方に位置している。 The ring-shaped portion 57 is formed in a flange shape from the front end (the end opposite to the small-diameter portion) of the large-diameter portion 23 and extends outward in the radial direction of the large-diameter portion 23. The folded portion 59 protrudes from the outer periphery of the ring-shaped portion 57 toward the small diameter portion 25 (rear side). Therefore, the large-diameter portion 23 where the ring-shaped portion 57 exists on the outside is a double circular tube of the large-diameter portion 23 and the folded portion 59. Further, the rear end of the folded portion 59 (the end opposite to the ring-shaped portion 57) is located in front of the rear end of the large-diameter portion 23 in the front-rear direction (longitudinal direction of the sleeve 21a).
　そして、リング状部５７と２重の円管状になっている箇所（大径部２３と折り返し部５９との間の空間）とでシールド編組線収容部５５が形成されている。 And the shield braided wire accommodation part 55 is formed by the ring-shaped part 57 and the location (space between the large diameter part 23 and the folding | turning part 59) which is a double circular tube shape.
　シールドコネクタ３ａでは、シールド電線１１の長手方向一端側の部位（前後方向で第１の部位Ｐ１と第２の部位Ｐ２との間の部位）は、外部被覆体２７とシールド編組線１９とが不存在であることにより、内部被覆体２９が露出している状態でハウジング５内に挿入されている。 In the shield connector 3a, the part on the one end side in the longitudinal direction of the shielded electric wire 11 (the part between the first part P1 and the second part P2 in the front-rear direction) is not connected to the outer covering 27 and the shield braided wire 19. By being present, it is inserted into the housing 5 with the inner covering 29 exposed.
　そして、シールド電線１１の内部被覆体２９が露出している部位にシール材９が設けられており、また、スリーブ２１ａのシールド編組線収容部５５の前面（環状で平面状の前面）６１が、シール材９の位置決めをしている構成になっている。なお、シール材９は底面４３とスリーブ２１ａのシールド編組線収容部５５の前面６１とに挟まれていることで前後方向の圧縮力を受け、僅かに弾性変形している。この弾性変形によるポアソン比に応じて、シール材９の内周が内部被覆体２９を押圧し、シール材９の外周がシール材設置部３９の内面を押圧している。これにより、シール材９のシール性が一層向上する。 And the sealing material 9 is provided in the site | part which the inner coating | covering body 29 of the shield electric wire 11 is exposed, Moreover, the front surface (annular and plane front surface) 61 of the shield braided wire accommodating part 55 of the sleeve 21a is provided. The sealing material 9 is positioned. The sealing material 9 is sandwiched between the bottom surface 43 and the front surface 61 of the shield braided wire receiving portion 55 of the sleeve 21a, so that it receives a compressive force in the front-rear direction and is slightly elastically deformed. In accordance with the Poisson's ratio due to this elastic deformation, the inner periphery of the sealing material 9 presses the inner covering 29, and the outer periphery of the sealing material 9 presses the inner surface of the sealing material installation portion 39. Thereby, the sealing performance of the sealing material 9 is further improved.
　第２実施形態に係るシールド編組線の接続構造１ａによれば、シールド編組線１９の端部を収容するシールド編組線収容部５５がスリーブ２１ａに設けられている。このため、予期せぬなんらかの要因でシールド編組線１９の端部がほつれてしまっても、このほつれによって不具合が発生することを、構成を煩雑にすることなく防止することができる。また、シールド編組線１９の端部によって、シール材９やハウジング５が傷付くおそれを無くすことができる。 According to the shield braided wire connection structure 1a according to the second embodiment, the sleeve 21a is provided with the shield braided wire accommodating portion 55 that accommodates the end of the shield braided wire 19. For this reason, even if the end portion of the shield braided wire 19 is frayed due to some unexpected factor, it is possible to prevent the flaw from being caused by this fraying without complicating the configuration. Further, the end of the shield braided wire 19 can eliminate the risk of the seal material 9 and the housing 5 being damaged.
　また、シールドコネクタ３ａによれば、シールド編組線収容部５５がシール材９の位置決めをしているので、シール材９を保持するためのリヤホルダが不要になる。このため、シールドコネクタ３ａの構成が簡素化されており、シールドコネクタ３ａの前後方向の寸法を小さくすることができる。 Further, according to the shield connector 3a, the shield braided wire accommodating portion 55 positions the seal material 9, so that a rear holder for holding the seal material 9 becomes unnecessary. For this reason, the configuration of the shield connector 3a is simplified, and the size of the shield connector 3a in the front-rear direction can be reduced.
　また、シールドコネクタ３ａによれば、スリーブ２１ａがシール材９の弾性によって後側に付勢されているので、シールド編組線１９を挟み込む力をスリーブ２１ａが常に発生することができ、振動等によって、スリーブ２１ａのシールド編組線１９を挟み込む力が小さくなることを無くすことができる。 Further, according to the shield connector 3a, since the sleeve 21a is urged rearward by the elasticity of the sealing material 9, the sleeve 21a can always generate a force for sandwiching the shield braided wire 19, and by vibration or the like, It is possible to eliminate a reduction in the force for sandwiching the shield braided wire 19 of the sleeve 21a.
　なお、第２実施形態に係るシールド編組線の接続構造１ａにおいても、図５（ｂ）、５（ｃ）、６と同様の変形をすることができる。 Note that the shield braided wire connection structure 1a according to the second embodiment can be modified in the same manner as in FIGS. 5B, 5C, and 6. FIG.
　本発明によれば、シールド編組線がはずれにくいシールド編組線の接続構造を容易に得ることができる。 According to the present invention, it is possible to easily obtain a shield braided wire connection structure in which the shield braided wire is difficult to come off.
