特に、前記のように電気自動車やハイブリッド自動車においては、ノイズ対策としてシールド付きの電線を用いることが多いが、シールドと接地回路との電気的接続を確実に行うのは難しく、その為の作業も手間のかかるものである。接続を確実にするには、シールド付き電線用のコネクタの構造を複雑化せざるを得ず、これによりコストアップの要因ともなっている。   In particular, in electric vehicles and hybrid vehicles as described above, shielded wires are often used as noise countermeasures, but it is difficult to ensure electrical connection between the shield and the ground circuit, and work for that is also required. It takes time. In order to ensure the connection, the structure of the connector for the shielded electric wire has to be complicated, which causes a cost increase.

この発明の目的は、車載における電線接続強度、防水性を確保し、振動がかかっても電線のシールドと接地回路との接続を確実に行うことが可能となり、シンプルな構造でかつ低コストで製作可能なシールド付き電線用コネクタを提供することである。   The object of the present invention is to secure the wire connection strength and waterproofness in the vehicle, and to make sure the connection between the wire shield and the grounding circuit is possible even when vibration is applied. It is to provide a shielded wire connector that is possible.

The inner diameters of the front hole portion 8aa and the rear hole portion 8ac are the minimum hole diameters into which the insulating coating 4, the conductive sleeve 9, and the waterproof material holder 10 of the shielded electric wire 2 can be inserted without difficulty.

防水材ホルダ10は、コネクタ本体8の中間孔部8abに挿入されて、前側面が導電性スリーブ9に突き当てられ、かつ後側面が前記締め付けホルダ13に突き当てられる。防水材ホルダ10は、電線防水用パッキング11および内部防水用パッキング12を、後側および前側に保持すると共に、締め付けホルダ13の締め付け力を導電性スリーブ9に伝達する部材であって、鋼材等の金属製または合成樹脂製の硬い素材でリング状に形成されている。   The waterproof material holder 10 is inserted into the intermediate hole portion 8ab of the connector main body 8, the front side surface is abutted against the conductive sleeve 9, and the rear side surface is abutted against the tightening holder 13. The waterproof material holder 10 is a member that holds the electric wire waterproof packing 11 and the internal waterproof packing 12 on the rear side and the front side, and transmits the tightening force of the tightening holder 13 to the conductive sleeve 9. It is formed in a ring shape from a hard material made of metal or synthetic resin.

防水材ホルダ10は、図6に示すように、内周面から後側面に渡る内側環状凹部21が設けられ、かつ外周面から前端面に渡る外側環状凹部22が設けられている。内側環状凹部21の内周面21aは、底側が縮径するテーパ状面とされている。外側環状凹部22は断面矩形状とされている。内側環状凹部21および外側環状凹部22にそれぞれ一部または全体が入るように、図1の前記電線防水用パッキング11および内部防水用パッキング12が配置される。   As shown in FIG. 6, the waterproof material holder 10 is provided with an inner annular recess 21 that extends from the inner peripheral surface to the rear side surface, and an outer annular recess 22 that extends from the outer peripheral surface to the front end surface. The inner peripheral surface 21a of the inner annular recess 21 is a tapered surface whose diameter is reduced on the bottom side. The outer annular recess 22 has a rectangular cross section. The wire waterproof packing 11 and the inner waterproof packing 12 shown in FIG. 1 are arranged so that a part or the whole of the inner annular recess 21 and the outer annular recess 22 are inserted.

電線防水用パッキング11は、シールド付き電線2の外周面と防水材ホルダ10との間を密封する部材であり、ゴムまたは合成樹脂製でリング状の部材からなる。電線防水用パッキング11の断面形状は、締め付けホルダ13で防水材ホルダ10の内側環状凹部21内に押し込まれることでシールド付き電線2の外周面と防水材ホルダ10との密で接触圧の高い面接触が得られる形状であることが好ましく、この実施形態では、図7(A)および図4に示すように、外周面の周方向複数箇所における前側部分に、変形部逃がし用凹部11aを有する形状とされている。変形部逃がし用凹部11aは、電線防水用パッキング11の弾性変形した部分を逃がすことによって変形し易くする凹部である。   The wire waterproof packing 11 is a member that seals between the outer peripheral surface of the shielded wire 2 and the waterproof material holder 10, and is made of a ring or a member made of rubber or synthetic resin. The cross-sectional shape of the electric wire waterproofing packing 11 is such that the outer peripheral surface of the shielded electric wire 2 and the waterproof material holder 10 are dense and have a high contact pressure by being pushed into the inner annular recess 21 of the waterproof material holder 10 by the tightening holder 13. In this embodiment, as shown in FIG. 7 (A) and FIG. 4, a shape having deformed portion relief recesses 11a at the front side portions at a plurality of locations in the circumferential direction of the outer peripheral surface is preferable. It is said that. The deformed portion relief recess 11a is a recess that is easily deformed by allowing the elastically deformed portion of the wire waterproof packing 11 to escape.

電線防水用パッキング11の断面形状は、この他に例えば図7(B)〜(D)にそれぞれ示すように、長方形状や、外周面がテーパ状となった円すい台状、円形状等の種々の形状が採用でき、また同図に示すような中空形状としても、また中実形状としてもよい。   In addition to this, for example, as shown in FIGS. 7B to 7D, the cross-sectional shape of the wire waterproof packing 11 is various, such as a rectangular shape, a truncated cone shape having a tapered outer peripheral surface, and a circular shape. The shape may be adopted, and may be a hollow shape as shown in the figure or a solid shape.

シールド接続用ばね14は、導電性スリーブ9の端面とコネクタ本体8との接触性を高めるために介在させる部材であって、導電性とばね製を持つ金属製等の部材である。シールド接続用ばね14は、例えば図8に示す波座金形状、図9に示す菊座金(歯突き座金とも呼ばれる)形状、または図10に示す一つ割りスプリングワッシャ形状とされる。   The shield connection spring 14 is a member interposed to improve the contact between the end face of the conductive sleeve 9 and the connector main body 8, and is a member made of metal having conductivity and spring. The shield connecting spring 14 has, for example, a wave washer shape shown in FIG. 8, a star washer (also referred to as a toothed washer) shape shown in FIG. 9, or a one-part spring washer shape shown in FIG.

図1の締め付けホルダ13は、鋼材等の金属または合成樹脂等の硬い素材で形成され、前部の外周面が雄ねじ部23とされている。締め付けホルダ13は、コネクタ本体8の雌ねじ部17にねじ込まれることで、電線防水用パッキング11を押し付けると共に防水材ホルダ10に突き当てられてこの防水材ホルダ10により導電性スリーブ9をコネクタ本体8の前側の径変化面8adに押し付け状態とする。   The fastening holder 13 of FIG. 1 is formed of a hard material such as a metal such as steel or a synthetic resin, and the outer peripheral surface of the front portion is a male screw portion 23. The tightening holder 13 is screwed into the female thread portion 17 of the connector main body 8, thereby pressing the electric wire waterproofing packing 11 and being abutted against the waterproof material holder 10, so that the conductive sleeve 9 is attached to the connector main body 8 by the waterproof material holder 10. The state is pressed against the front diameter change surface 8ad.

上記構成のシールド付き電線用コネクタ1による接続作業を説明する。シールド付き電線2に、締め付けホルダ13、電線防水用パッキング11、防水材ホルダ10、内部防水用パッキング12、導電性スリーブ9、およびシールド接続用ばね14を順次挿通する。この後、図5に示すようにシールド付き電線2の絶縁被覆4、シールド5および外皮6を剥ぎ、シールド5を折り返してその外周に導電性スリーブ9を前述のように止め付ける。この後、シールド付き電線2をコネクタ本体8に通し(図3の状態)、締め付けホルダ13を図1のように締め付ける。この後、端子7の取付けを行う。   Connection work by the shielded electric wire connector 1 having the above-described configuration will be described. A tightening holder 13, a wire waterproof packing 11, a waterproof material holder 10, an internal waterproof packing 12, a conductive sleeve 9, and a shield connection spring 14 are sequentially inserted into the shielded electric wire 2. After that, as shown in FIG. 5, the insulation coating 4, the shield 5 and the outer skin 6 of the shielded electric wire 2 are peeled off, the shield 5 is folded back, and the conductive sleeve 9 is fastened to the outer periphery thereof as described above. Thereafter, the shielded electric wire 2 is passed through the connector body 8 (the state shown in FIG. 3), and the fastening holder 13 is tightened as shown in FIG. Thereafter, the terminal 7 is attached.

この構成のシールド付き電線用コネクタ1によると、シールド付き電線2のシールド折り返し部分5aに被さってシールド5と導通状態となった導電性スリーブ9が、コネクタ本体8の内周に嵌まっている。この導電性スリーブ9は、締め付けホルダ10の締め付けにより、防水材ホルダ10で前側へ押され、コネクタ本体8の段差状の径変化面8adに押し付けられる。その押し付け箇所で、シールド付き電線2のシールド5とコネクタ本体8とが電気的に接続され、接地回路が接続されることになる。このように軸方向に押し付け状態として接触させるため、車載における電線接続強度が確保され、振動がかかってもシールド付き電線2の接地回路の接続を確実に維持することが可能となる。
この接続箇所では、シールド接続用ばね14が介在するため、締め付けホルダ13の締め込みでのがたつきや、経年結果での緩みが多少あった場合でも、接続が確保される。
According to the shielded electric wire connector 1 having this configuration, the conductive sleeve 9 that is in a conductive state with the shield 5 by covering the shield folded portion 5 a of the shielded electric wire 2 is fitted to the inner periphery of the connector body 8. When the tightening holder 10 is tightened, the conductive sleeve 9 is pushed forward by the waterproof material holder 10 and is pressed against the step-shaped diameter change surface 8ad of the connector body 8. At the pressed portion, the shield 5 of the shielded electric wire 2 and the connector body 8 are electrically connected, and the ground circuit is connected. In this way, since the contact is made in the pressed state in the axial direction, the wire connection strength in the vehicle is ensured, and the connection of the ground circuit of the shielded wire 2 can be reliably maintained even when vibration is applied.
Since the shield connection spring 14 is interposed at this connection location, the connection is ensured even if there is some looseness due to tightening of the tightening holder 13 or some aging.

また、導電性スリーブ9は、その外周面の全周から面的にプレスして全面的に縮径させ、その上でさらにスポット的なかしめにより陥没部19を形成してシールド付き電線2のシールド折り返し部分5aに食い込ませている。そのため、導電性スリーブ9のシールド付き電線2に対する固定強度が向上し、シールド5と導電性スリーブ9との電気的な接触がより一層確実に保たれる。   Further, the conductive sleeve 9 is pressed from the entire circumference of the outer peripheral surface to reduce the diameter of the entire surface, and further, a recessed portion 19 is formed by spot caulking thereon to shield the shielded electric wire 2. It digs into the folded portion 5a. Therefore, the fixing strength of the conductive sleeve 9 to the shielded electric wire 2 is improved, and the electrical contact between the shield 5 and the conductive sleeve 9 is more reliably maintained.

防水については、コネクタ本体8と防水材ホルダ10の間に内部防水用パッキング12を挟み、防水材ホルダ10と締め付けホルダ13の間に電線防水用パッキング11を挟み込んだ状態で締め付けホルダ13を取付けている。そのため、シールド付き電線2とコネクタ本体2との間の防水性が得られる。この場合に、電線防水用パッキング11は、防水材ホルダ10の内周面から後側面に渡って形成された内側環状凹部21に一部が入った状態で締め付けホルダ13に押されるため、シールド付き電線2の外皮6に食い込むように電線防水用パッキング11が変形し、接触面の押し付け圧が強くて、優れた防水性が得られる。前記内側環状凹部21の内周面は底側が縮径するテーパ状面であるため、電線防水用パッキング11は締め付けホルダ13で軸方向に押されることで、縮径状態に弾性変形する。そのため、シールド付き電線2の外周により強く接触し、防水性がさらに向上する。防水材ホルダ10とコネクタ本体8との間についても、防水材ホルダ10の外周面から前側面に渡って形成された外側環状凹部22に内部防水用パッキング12を配置しているため、内部防水用パッキング12がコネクタ本体8の内面に強く押し付けられ、確実な防水性が得られる。   For waterproofing, the inner waterproofing packing 12 is sandwiched between the connector body 8 and the waterproofing material holder 10, and the fastening holder 13 is attached with the electric wire waterproofing packing 11 sandwiched between the waterproofing material holder 10 and the fastening holder 13. Yes. Therefore, waterproofness between the shielded electric wire 2 and the connector main body 2 is obtained. In this case, the wire waterproofing packing 11 is pressed by the tightening holder 13 in a state where a part of the inner annular recess 21 formed from the inner peripheral surface to the rear side surface of the waterproof material holder 10 is inserted, so that the shield is provided. The wire waterproofing packing 11 is deformed so as to bite into the outer skin 6 of the electric wire 2, the pressing pressure on the contact surface is strong, and an excellent waterproof property is obtained. Since the inner peripheral surface of the inner annular recess 21 is a tapered surface whose diameter is reduced on the bottom side, the wire waterproof packing 11 is elastically deformed into a reduced diameter state by being pushed in the axial direction by the tightening holder 13. Therefore, it contacts more strongly with the outer periphery of the shielded electric wire 2 and the waterproofness is further improved. Also between the waterproof material holder 10 and the connector body 8, the internal waterproof packing 12 is disposed in the outer annular recess 22 formed from the outer peripheral surface of the waterproof material holder 10 to the front side surface. The packing 12 is strongly pressed against the inner surface of the connector main body 8, and a certain waterproof property is obtained.

このように、シールド付き電線2のシールド5と接地回路との接続を確実になされ、また確実な防水性が得られるため、接続やシールの確実化のための他の煩雑な構成が不要であり、シンプルな構造となって低コストで製作可能である。また、締め付けホルダ13の締め付け作業で導電性スリーブ9の導電性の確保とコネクタ本体8内の防水性の確保との両方が同時に行え、作業性にも優れる。   In this way, the shield 5 of the shielded electric wire 2 is reliably connected to the ground circuit, and a reliable waterproof property is obtained, so that no other complicated configuration for ensuring connection and sealing is unnecessary. It is simple and can be manufactured at low cost. In addition, it is possible to simultaneously secure the conductivity of the conductive sleeve 9 and ensure the waterproofness in the connector main body 8 by the tightening operation of the tightening holder 13, and the workability is excellent.

締め付けホルダ13は、外周の雄ねじ部23をコネクタ本体8の雌ねじ部17に螺合させて締め付けるようにしているため、簡素な構成で導電性スリーブ9および各パッキング11,12の強い押し付けが得られ、また押し付け力を得るための作業も回転により締め付けるだけでよくて、簡単である。   Since the tightening holder 13 is tightened by screwing the outer peripheral male threaded portion 23 into the female threaded portion 17 of the connector main body 8, strong pressing of the conductive sleeve 9 and the packings 11 and 12 can be obtained with a simple configuration. In addition, the operation for obtaining the pressing force is simple and requires only tightening by rotation.

なお、コネクタ本体8への締め付けホルダ13の取付形態は、上記実施形態では、締め付けホルダ13の外周の雄ねじ部23を用いるようにしたが、前記電線防水用パッキング11および防水材ホルダ10と共に導電性スリーブ9を押し付けることができる形態であればよく、他に種々の構成が採用できる。例えば、図示は省略するが、締め付けホルダ13の前部を二重筒状として、その外側筒部の内周に設けた雌ねじ部をコネクタ本体8の外周に設けられた雄ねじ部にねじ込み内側筒部で防水材ホルダ10を押し付けるようにしてもよく、またコネクタ本体8または締め付けホルダ13をかしめることで締め付けホルダ13をコネクタ本体8に取付けるようにしてもよい。   In addition, in the said embodiment, although the external thread part 23 of the outer periphery of the clamp | tightening holder 13 was used for the attachment form of the clamp | tightening holder 13 to the connector main body 8, it is electroconductive with the said packing 11 for electric wire waterproofing and the waterproof material holder 10. FIG. Any configuration capable of pressing the sleeve 9 may be used, and various other configurations may be employed. For example, although not shown, the front portion of the tightening holder 13 has a double cylindrical shape, and a female screw portion provided on the inner periphery of the outer cylindrical portion is screwed into a male screw portion provided on the outer periphery of the connector body 8. The waterproof material holder 10 may be pressed with the connector body 8 or the tightening holder 13 may be attached to the connector body 8 by caulking the connector body 8 or the tightening holder 13.

今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。   The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
