Description

本発明は、電線に取り付けられる環状部材に関する。   The present invention relates to an annular member attached to an electric wire.

例えば、絶縁被覆で覆われた被覆電線の芯線に電気的に接続される端子として、被覆電線を挿入した金属製の筒部から内側に突片を延出させ、絶縁被覆を突き破った突片の先端を被覆電線の内部の芯線に到達させるものが知られている（例えば、特許文献１，２）。   For example, as a terminal that is electrically connected to the core wire of a covered electric wire covered with an insulating coating, a protruding piece is extended inward from a metal cylinder portion into which the covered electric wire is inserted, and the protruding piece that has broken through the insulating coating There are known devices that allow the tip to reach the core wire inside the covered electric wire (for example, Patent Documents 1 and 2).

特開２００１−１２６７８５号公報JP 2001-126785 A 実開昭６０−７５９６８号公報Japanese Utility Model Publication No. 60-75968

上述した端子は、芯線に対する電気的接続を容易に得られる点で優れている。しかし、被覆電線に対する環状部材の位置が被覆電線の中心軸に沿って突片の先端側から基端側に向けてずれると、絶縁被覆を突き破った突片の先端が絶縁被覆から抜け出し、突片と芯線との電気的接続が解消されてしまう。   The terminals described above are excellent in that electrical connection to the core wire can be easily obtained. However, if the position of the annular member with respect to the covered wire is shifted from the distal end side to the proximal end side of the protruding piece along the central axis of the covered wire, the tip of the protruding piece that broke through the insulating coating comes out of the insulating coating, and the protruding piece The electrical connection between the cable and the core wire is eliminated.

このような問題は、被覆電線に芯線の端子を取り付ける場合に限らず、例えば、電線の保護部材（カラー）やストッパリングを取り付ける場合、シールドケーブルの編組線にシールドシェルを取り付ける場合等、電線に環状部材を取り付ける場合にも共通する。   Such problems are not limited to the case where a core wire terminal is attached to a covered electric wire. For example, when attaching a protective member (collar) or stopper ring of an electric wire, attaching a shield shell to a braided wire of a shield cable, etc. This is also common when attaching an annular member.

本発明は前記事情に鑑みなされたもので、本発明の目的は、電線に対する相対位置が電線の挿入方向にずれても、電線に対する取付状態を適切に保持することができる電線取付用環状部材を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an annular member for attaching an electric wire that can appropriately maintain an attachment state with respect to the electric wire even when the relative position to the electric wire is shifted in the insertion direction of the electric wire. It is to provide.

電線が挿入される筒部と、
前記筒部に片持ち支持されて該筒部に対する前記電線の挿入方向における一方側から他方側に延出し、前記筒部の内側に変形させることで前記電線の表面を突き破って該電線の内部に刺し込まれる第１係止部が先端に形成された可撓性の第１突片と、
前記第１突片に片持ち支持されて前記挿入方向における他方側から一方側に延出し、前記筒部の内側に変形させることで前記電線の表面を突き破って該電線の内部に刺し込まれる第２係止部が先端に形成された可撓性の第２突片と、
を備える。 In order to achieve the above object, an annular member for attaching an electric wire according to the first aspect of the present invention comprises:
A cylinder part into which the electric wire is inserted;
Cantilevered by the cylindrical portion, extends from one side to the other side in the insertion direction of the electric wire with respect to the cylindrical portion, and is deformed to the inside of the cylindrical portion to break through the surface of the electric wire and enter the inside of the electric wire. A flexible first protrusion having a first locking portion to be inserted formed at the tip;
The first protrusion is cantilevered and extended from the other side to the one side in the insertion direction, and is deformed to the inside of the cylindrical portion to penetrate the surface of the electric wire and is inserted into the electric wire. 2 flexible second projecting piece formed with a locking portion at the tip;
Is provided.

本発明の第１の態様による電線取付用環状部材によれば、筒部の内側に第１突片を変形させると、筒部に挿入された電線が筒部に対して挿入方向の他方側から一方側に相対移動したときに、第１突片の先端の第１係止部が、電線の表面を突き破って電線の内部に刺し込まれる。電線の内部に第１係止部が刺し込まれると、挿入方向の他方側から一方側への電線に対する筒部のさらなる相対移動が第１突片によって規制される。   According to the annular member for attaching an electric wire according to the first aspect of the present invention, when the first projecting piece is deformed inside the cylindrical portion, the electric wire inserted into the cylindrical portion is from the other side in the insertion direction with respect to the cylindrical portion. When relatively moving to one side, the first locking portion at the tip of the first protruding piece penetrates the surface of the electric wire and is inserted into the electric wire. When the first locking portion is inserted into the electric wire, further relative movement of the tube portion with respect to the electric wire from the other side to the one side in the insertion direction is restricted by the first projecting piece.

但し、筒部に挿入された電線が筒部に対して挿入方向の一方側から他方側に相対移動されると、電線に刺し込まれた第１係止部が電線から引き抜かれる。第１係止部が電線から引き抜かれると、挿入方向の他方側から一方側への電線に対する筒部の相対移動を第１突片によって規制できなくなる。   However, when the electric wire inserted into the cylindrical portion is relatively moved from one side to the other side in the insertion direction with respect to the cylindrical portion, the first locking portion inserted into the electric wire is pulled out from the electric wire. When the first locking portion is pulled out from the electric wire, the first protrusion cannot restrict the relative movement of the tube portion with respect to the electric wire from the other side in the insertion direction to the one side.

ここで、筒部の内側に第２突片を変形させると、筒部に挿入された電線が筒部に対して挿入方向の一方側から他方側に相対移動したときに、第２突片の先端の第２係止部が、電線の表面を突き破って電線の内部に刺し込まれる。電線の内部に第２係止部が刺し込まれると、挿入方向の一方側から他方側への電線に対する筒部のさらなる相対移動が第２突片によって規制される。   Here, when the second projecting piece is deformed inside the tube portion, when the electric wire inserted into the tube portion moves relative to the tube portion from one side to the other side in the insertion direction, the second projecting piece The second locking portion at the tip breaks through the surface of the electric wire and is inserted into the electric wire. When the second locking portion is inserted into the electric wire, further relative movement of the tube portion with respect to the electric wire from one side to the other side in the insertion direction is restricted by the second projecting piece.

このため、第１突片の第１係止部が電線に刺し込まれている状態で、第２突片の第２係止部が電線に刺し込まれていると、挿入方向の一方側から他方側への電線に対する筒部の相対移動が第２突片によって規制されるので、電線に刺し込まれた第１係止部の電線からの引き抜きが規制される。   For this reason, when the 2nd latching part of the 2nd projection piece is stabbed in the electric wire in the state where the 1st latching part of the 1st projection piece is pierced in the electric wire, from one side of the insertion direction Since the relative movement of the cylindrical portion with respect to the electric wire to the other side is restricted by the second projecting piece, the extraction of the first locking portion inserted into the electric wire from the electric wire is restricted.

また、筒部に挿入された電線が筒部に対して挿入方向の他方側から一方側に相対移動されると、電線に刺し込まれた第２係止部が電線から引き抜かれる。第２係止部が電線から引き抜かれると、挿入方向の一方側から他方側への電線に対する筒部の相対移動を第２突片によって規制できなくなる。   In addition, when the electric wire inserted into the cylindrical portion is relatively moved from the other side in the insertion direction to the one side with respect to the cylindrical portion, the second locking portion inserted into the electric wire is pulled out from the electric wire. When the second locking portion is pulled out from the electric wire, the relative movement of the tube portion with respect to the electric wire from one side to the other side in the insertion direction cannot be restricted by the second projecting piece.

しかし、第２突片の第２係止部が電線に刺し込まれている状態で、第１突片の第１係止部が電線に刺し込まれていると、挿入方向の他方側から一方側への電線に対する筒部の相対移動が第１突片によって規制されるので、電線に刺し込まれた第２係止部の電線からの引き抜きが規制される。   However, when the first locking portion of the first protrusion is inserted into the electric wire in the state where the second locking portion of the second protrusion is inserted into the electric wire, Since the relative movement of the tube portion with respect to the electric wire to the side is restricted by the first protrusion, the extraction of the second locking portion inserted into the electric wire from the electric wire is restricted.

したがって、第１の突片及び第２の突片を筒部の内側に変形させて第１の係止部及び第２の係止部を電線の内部に刺し込ませることで、電線に対する筒部の挿入方向における相対移動を一方側から他方側及び他方側から一方側の双方について同時に規制することができる。   Accordingly, the first projecting piece and the second projecting piece are deformed to the inside of the cylindrical portion, and the first engaging portion and the second engaging portion are inserted into the inside of the electric wire, so that the cylindrical portion with respect to the electric wire is obtained. The relative movement in the insertion direction can be restricted simultaneously from one side to the other side and from the other side to the one side.

よって、電線に対する相対位置が電線の挿入方向にずれても、電線に対する取付状態を適切に保持することができる。   Therefore, even if the relative position with respect to the electric wire is shifted in the insertion direction of the electric wire, the attachment state with respect to the electric wire can be appropriately maintained.

また、本発明の第３の態様による電線取付用環状部材のように、本発明の第２の態様による電線取付用環状部材において、前記筒部、前記第１突片及び前記第２突片は金属材料で形成されており、前記絶縁被覆に刺し込まれた前記第１係止部及び前記第２係止部のうち少なくとも一方は、前記絶縁被覆を貫通して前記芯線に電気的に接続される構成としてもよい。   Moreover, like the annular member for electric wire attachment according to the third aspect of the present invention, in the annular member for electric wire attachment according to the second aspect of the present invention, the cylindrical portion, the first protruding piece and the second protruding piece are At least one of the first locking portion and the second locking portion that is formed of a metal material and is inserted into the insulating coating penetrates the insulating coating and is electrically connected to the core wire. It is good also as a structure to be.

The tip of the second projecting piece 13 constitutes a second locking portion 19 that is inserted into the electric wire 3 inserted into the tubular portion 10 by bending the second projecting piece 13 inwardly of the tubular portion 10.

図２の電線３は、図１の電線取付用環状部材１を取り付ける外側部３１と、外側部３１により表面が被覆された内側部３３とを有している。   The electric wire 3 in FIG. 2 has an outer portion 31 to which the electric wire attaching annular member 1 in FIG. 1 is attached, and an inner portion 33 whose surface is covered with the outer portion 31.

図１の電線取付用環状部材１を図２の電線３に取り付ける際には、まず、筒部１０に電線３を挿入する。そして、図３の断面図に示すように、筒部１０の各第１突片１２及び第２突片１３を、電線３を挿入した筒部１０の内側にそれぞれ曲げ変形させる。   When attaching the wire-attaching annular member 1 of FIG. 1 to the wire 3 of FIG. 2, first, the wire 3 is inserted into the cylindrical portion 10. Then, as shown in the cross-sectional view of FIG. 3, the first projecting pieces 12 and the second projecting pieces 13 of the tubular portion 10 are bent and deformed inside the tubular portion 10 in which the electric wires 3 are inserted.

筒部１０の内側に曲げ変形させた第１突片１２の先端の第１係止部１５は、筒部１０に挿入した電線３の外側部３１の表面を突き破って外側部３１の内側に刺し込まれる。外側部３１の内側に刺し込まれた第１係止部１５は、電線３の挿入方向Ｘにおける筒部１０の他端側から一端側（フランジ部２０側）への電線３の筒部１０に対する相対移動を規制する。   The first locking portion 15 at the tip of the first protruding piece 12 bent and deformed inside the tube portion 10 penetrates the surface of the outer portion 31 of the electric wire 3 inserted into the tube portion 10 and pierces the outer portion 31. Is included. The first locking portion 15 inserted inside the outer portion 31 corresponds to the tubular portion 10 of the electric wire 3 from the other end side of the tubular portion 10 in the insertion direction X of the electric wire 3 to one end side (flange portion 20 side). Regulate relative movement.

また、筒部１０の内側に曲げ変形させた第２突片１３の先端の第２係止部１９は、筒部１０に挿入した電線３の外側部３１の表面を突き破って外側部３１の内側に刺し込まれる。外側部３１の内側に刺し込まれた第２係止部１９は、電線３の挿入方向Ｘにおける筒部１０の一端側（フランジ部２０側）から他端側への電線３の筒部１０に対する相対移動を規制する。   Further, the second locking portion 19 at the tip of the second projecting piece 13 that is bent and deformed inside the tube portion 10 breaks through the surface of the outer portion 31 of the electric wire 3 inserted into the tube portion 10 to the inner side of the outer portion 31. Stabbed in. The second locking portion 19 stabbed inside the outer portion 31 corresponds to the tubular portion 10 of the electric wire 3 from the one end side (flange portion 20 side) to the other end side in the inserting direction X of the electric wire 3.

このように電線３の外側部３１に取り付けた電線取付用環状部材１は、筒部１０に対して電線３が挿入方向Ｘにおける筒部１０の一端側（フランジ部２０側）から他端側に相対移動すると、第１係止部１５が電線３の外側部３１から引き抜かれる。   In this way, the wire-attaching annular member 1 attached to the outer portion 31 of the electric wire 3 moves from one end side (flange portion 20 side) to the other end side of the tubular portion 10 in the insertion direction X with respect to the tubular portion 10. When the relative movement is performed, the first locking portion 15 is pulled out from the outer side portion 31 of the electric wire 3.

電線３の外側部３１から第１係止部１５が引き抜かれると、筒部１０の他端側から一端側（フランジ部２０側）への電線３の筒部１０に対する相対移動を、第１突片１２の第１係止部１５によって規制できなくなる。   When the first locking portion 15 is pulled out from the outer side portion 31 of the electric wire 3, the relative movement of the electric wire 3 from the other end side of the cylindrical portion 10 to the one end side (flange portion 20 side) relative to the cylindrical portion 10 is changed to the first protrusion. It cannot be regulated by the first locking portion 15 of the piece 12.

しかし、電線３の挿入方向Ｘにおける筒部１０の一端側（フランジ部２０側）から他端側への電線３の筒部１０に対する相対移動は、電線３の外側部３１に第２係止部１９が刺し込まれた第２突片１３によって規制される。このため、筒部１０に対する電線３の相対移動で第１係止部１５が電線３の外側部３１から引き抜かれることが抑制される。   However, relative movement of the wire 3 from the one end side (flange portion 20 side) to the other end side of the tube portion 10 in the insertion direction X of the wire 3 is caused by the second locking portion on the outer portion 31 of the wire 3. 19 is regulated by the second protruding piece 13 in which 19 is inserted. For this reason, it is suppressed that the 1st latching | locking part 15 is pulled out from the outer side part 31 of the electric wire 3 by the relative movement of the electric wire 3 with respect to the cylinder part 10. FIG.

また、筒部１０に対して電線３が挿入方向Ｘにおける筒部１０の他端側から一端側（フランジ部２０側）に相対移動すると、第２係止部１９が電線３の外側部３１から引き抜かれる。   When the electric wire 3 moves relative to the cylindrical portion 10 from the other end side of the cylindrical portion 10 in the insertion direction X to one end side (flange portion 20 side), the second locking portion 19 moves from the outer portion 31 of the electric wire 3. Pulled out.

電線３の外側部３１から第２係止部１９が引き抜かれると、筒部１０の一端側（フランジ部２０側）から他端側への電線３の筒部１０に対する相対移動を、第２突片１３の第２係止部１９によって規制できなくなる。   When the second locking portion 19 is pulled out from the outer side portion 31 of the electric wire 3, the relative movement of the electric wire 3 relative to the cylindrical portion 10 from one end side (flange portion 20 side) to the other end side of the cylindrical portion 10 is changed to the second protrusion. It cannot be regulated by the second locking portion 19 of the piece 13.

しかし、電線３の挿入方向Ｘにおける筒部１０の他端側から一端側（フランジ部２０側）への電線３の筒部１０に対する相対移動は、電線３の外側部３１に第１係止部１５が刺し込まれた第１突片１２によって規制される。このため、筒部１０に対する電線３の相対移動で第２係止部１９が電線３の外側部３１から引き抜かれることが抑制される。   However, relative movement of the wire 3 from the other end side of the tube portion 10 in the insertion direction X of the wire 3 to the one end side (flange portion 20 side) relative to the tube portion 10 is caused by the first locking portion on the outer portion 31 of the wire 3. 15 is regulated by the first projecting piece 12 in which 15 is inserted. For this reason, it is suppressed that the 2nd latching | locking part 19 is pulled out from the outer side part 31 of the electric wire 3 by the relative movement of the electric wire 3 with respect to the cylinder part 10. FIG.

このように、本実施形態の電線取付用環状部材１によれば、第１突片１２及び第２突片１３を曲げ変形させてそれぞれの先端の第１係止部１５及び第２係止部１９を電線３の外側部３１に刺し込ませることで、筒部１０に対する電線３の挿入方向Ｘにおける相対移動を双方向とも同時に規制することができる。   As described above, according to the annular member 1 for electric wire attachment of the present embodiment, the first protrusions 12 and the second protrusions 13 are bent and deformed, and the first locking portions 15 and the second locking portions at the respective ends. By inserting 19 into the outer portion 31 of the electric wire 3, the relative movement in the insertion direction X of the electric wire 3 with respect to the tube portion 10 can be restricted simultaneously in both directions.

よって、筒部１０に対する電線３の相対位置が挿入方向Ｘにずれても、電線３の外側部３１に対する第１突片１２及び第２突片１３の第１係止部１５及び第２係止部１９の係止状態を保持し、電線３に対する電線取付用環状部材１の取付状態を適切に保持することができる。   Therefore, even if the relative position of the electric wire 3 with respect to the tubular portion 10 is shifted in the insertion direction X, the first locking portion 15 and the second locking portion of the first protruding piece 12 and the second protruding piece 13 with respect to the outer side portion 31 of the electric wire 3. The locking state of the part 19 can be maintained, and the attachment state of the wire attachment annular member 1 with respect to the electric wire 3 can be appropriately maintained.

なお、上述した電線３は、例えば、芯線を絶縁被覆で覆った被覆電線であってもよい。電線３が被覆電線である場合は、外側部３１が絶縁被覆に該当し、内側部３３が芯線に該当する。   In addition, the electric wire 3 mentioned above may be the covered electric wire which covered the core wire with the insulation coating, for example. When the electric wire 3 is a covered electric wire, the outer side part 31 corresponds to an insulation coating, and the inner side part 33 corresponds to a core wire.

そして、本実施形態の電線取付用環状部材１を、電線３を中心軸方向において位置決めするためのストッパ部材として用いる場合は、電線３の外側部３１に対して第１突片１２及び第２突片１３の第１係止部１５及び第２係止部１９を、筒部１０に対する電線３の相対移動を規制できる程度に刺し込めばよい。   And when using the annular member 1 for electric wire attachment of this embodiment as a stopper member for positioning the electric wire 3 in a central-axis direction, it is the 1st protrusion piece 12 and the 2nd protrusion with respect to the outer side part 31 of the electric wire 3. FIG. What is necessary is just to insert the 1st latching | locking part 15 and the 2nd latching | locking part 19 of the piece 13 to such an extent that the relative movement of the electric wire 3 with respect to the cylinder part 10 can be controlled.

また、本実施形態の電線取付用環状部材１を、電線３の芯線に電気的に接続された端子として用いる場合は、電線３の外側部３１に対して第１突片１２及び第２突片１３の第１係止部１５及び第２係止部１９のうち少なくとも一方を、外側部３１を貫通して内側部３３に到達するまで刺し込めばよい。   Moreover, when using the annular member 1 for electric wire attachment of this embodiment as a terminal electrically connected to the core wire of the electric wire 3, the 1st protrusion 12 and the 2nd protrusion with respect to the outer side part 31 of the electric wire 3 At least one of the 13 first locking portions 15 and the second locking portions 19 may be inserted until it penetrates the outer portion 31 and reaches the inner portion 33.

さらに、上述した電線３は、例えば、被覆電線の絶縁被覆の表面をノイズ保護用の編組線で被覆したシールドケーブルであってもよい。電線３がシールドケーブルである場合は、外側部３１が編組線に該当し、内側部３３が被覆電線に該当する。   Furthermore, the above-described electric wire 3 may be a shielded cable in which the surface of the insulation coating of the covered electric wire is covered with a braided wire for noise protection, for example. When the electric wire 3 is a shielded cable, the outer side part 31 corresponds to a braided wire, and the inner side part 33 corresponds to a covered electric wire.

そして、本実施形態の電線取付用環状部材１を、シールドケーブルの編組線をシールドケーブルの接続相手側の接地端子に接続するシールドシェルとして用いる場合は、電線３の外側部３１に対して第１突片１２及び第２突片１３の第１係止部１５及び第２係止部１９を、筒部１０が電線３の外側部３１に加締め固定される程度に刺し込めばよい。   And when using the annular member 1 for electric wire attachment of this embodiment as a shield shell which connects the braided wire of a shield cable to the grounding terminal of the other party of a shield cable, it is 1st with respect to the outer side part 31 of the electric wire 3. What is necessary is just to insert the 1st latching | locking part 15 and the 2nd latching | locking part 19 of the protrusion 12 and the 2nd protrusion 13 to such an extent that the cylinder part 10 is crimped and fixed to the outer side part 31 of the electric wire 3.

これにより、第１係止部１５及び第２係止部１９のうち少なくとも一方を電線３の外側部３１（編組線）に電気的に接続させて、電線取付用環状部材１をシールドシェルとして機能させることができる。   Accordingly, at least one of the first locking portion 15 and the second locking portion 19 is electrically connected to the outer portion 31 (braided wire) of the electric wire 3, and the electric wire attaching annular member 1 functions as a shield shell. Can be made.

また、第１係止部１５及び第２係止部１９の外周面側に、第１突片１２及び第２突片１３の先端に向かうにつれて先細りとなるテーパ面を形成してもよい。   Further, on the outer peripheral surface side of the first locking portion 15 and the second locking portion 19, a tapered surface that tapers toward the tips of the first protruding piece 12 and the second protruding piece 13 may be formed.

そのように形成すれば、筒部１０に対して電線３を挿入方向Ｘにおける筒部１０の他端側から一端側（フランジ部２０側）に相対移動させたときに、筒部１０の内側に曲げ変形させた第１突片１２の第１係止部１５が、電線３の外側部３１の表面を突き破って内側に刺し込まれ易くなるようにすることができる。   If formed in this way, when the electric wire 3 is moved relative to the cylindrical portion 10 from the other end side of the cylindrical portion 10 in the insertion direction X to one end side (flange portion 20 side), The first locking portion 15 of the first projecting piece 12 that has been bent and deformed can break through the surface of the outer portion 31 of the electric wire 3 and be easily inserted into the inner portion.

また、筒部１０に対して電線３を挿入方向Ｘにおける筒部１０の一端側（フランジ部２０側）から他端側に相対移動させたときに、筒部１０の内側に曲げ変形させた第２突片１３の第２係止部１９が、電線３の外側部３１の表面を突き破って内側に刺し込まれ易くなるようにすることができる。   In addition, when the wire 3 is moved relative to the tube portion 10 from the one end side (flange portion 20 side) of the tube portion 10 in the insertion direction X to the other end side, the wire 3 is bent and deformed inside the tube portion 10. The 2nd latching | locking part 19 of the 2 protrusion piece 13 can be made to penetrate the surface of the outer side part 31 of the electric wire 3, and to be easily stabbed inside.

さらに、本実施形態では、第１突片１２内に第２突片１３を形成したが、第２突片１３が第１突片１２から延出されて第１突片１２に片持ち支持されていれば、第１突片１２の外側に第２突片１３を形成して第１突片１２に接続する構成としてもよい。   Further, in the present embodiment, the second projecting piece 13 is formed in the first projecting piece 12, but the second projecting piece 13 extends from the first projecting piece 12 and is cantilevered by the first projecting piece 12.
