本考案は、コードの芯線同士を結合した結線部分を絶縁保護する結線絶縁保護 チューブに係り、特に結線部分を確実に絶縁保護することができる結線絶縁保護 チューブに関するものである。 The present invention relates to a wire connection insulation protection tube that insulates and protects a wire connection part connecting core wires of a cord, and particularly to a wire connection insulation protection tube that can reliably insulate and protect a wire connection part.
【０００２】[0002]
従来、コードの芯線同士を結合した結線部分を絶縁保護する手段としては絶縁 性テープがある。その詳細を図３を参照して説明する。 図において、１はコードである。このコート１は、芯線１０と、その芯線１０ を被覆する絶縁性の絶縁被覆管１１とからなる。このコード１の結線する端部の 絶縁被覆管１１を切除して芯線１０を裸線にする。 図において、２は圧着端子（スプライス端子）である。この圧着端子２は、例 えば導電性の柔らかい金属製からなり、円筒形状をなす。この圧着端子２の中に 前記コート１の裸線の芯線１０を、この図示の例では一方（左側）から１本のコ ード１の芯線１０を、また他方（右側）から２本のコード１の芯線１０を、それ ぞれ挿入し、その圧着端子２を外部から工具等で強く圧接して、３本のコードの 芯線１０を圧着結線する。 図において、３は絶縁性のテープである。この絶縁性テープ３を上述の３本の コード１の結線部分、すなわち３本のコード１の端部の絶縁被覆管１１及び裸線 の芯線１０及び圧着端子２の外側に巻装する。この結果、コード１の結線部分の 絶縁性を保つ。 Conventionally, an insulating tape has been used as a means for insulating and protecting the connecting portion where the core wires of the cord are connected to each other. The details will be described with reference to FIG. In the figure, 1 is a code. The coat 1 is composed of a core wire 10 and an insulating insulation coating tube 11 that covers the core wire 10. The insulation coating pipe 11 at the end of the cord 1 to be connected is cut off to leave the core wire 10 as a bare wire. In the figure, 2 is a crimp terminal (splice terminal). The crimp terminal 2 is made of, for example, a conductive soft metal and has a cylindrical shape. In this crimp terminal 2, a bare core wire 10 of the coat 1 is used, in this example, one core wire 10 of the cord 1 is provided from one side (left side), and two core wires are provided from the other side (right side). One core wire 10 is inserted into each core wire, and the crimp terminal 2 is strongly pressed from the outside with a tool or the like to crimp-connect the core wires 10 of the three cords. In the figure, 3 is an insulating tape. The insulating tape 3 is wound around the connecting portions of the above-mentioned three cords 1, that is, the insulating coated tube 11 at the ends of the three cords 1, the bare core wire 10 and the crimp terminal 2. As a result, the insulation of the connection part of the cord 1 is maintained.
【０００３】[0003]
ところが、上述の従来の絶縁性テープ３巻の場合では、絶縁性テープ３を巻く 必要があるので、その絶縁性テープ３を巻く作業が面倒である。また、コード１ の芯線１０と絶縁被覆管１１との境を絶縁性テープ３で確実に巻装して絶縁性を 確保する必要がある。さらに、絶縁テープ３を結線部分の芯線１０にも直接巻装 するので、強度的に弱い芯線１０に外力がかかり、その芯線１０が切断すること がある。その上、芯線１０が切断すると、その切断された芯線１０が絶縁テープ ３を突き破ることがあり、するとショートする虞がある。 However, in the case of three windings of the above-mentioned conventional insulating tape, it is necessary to wind the insulating tape 3, so that the work of winding the insulating tape 3 is troublesome. Further, it is necessary to securely wind the boundary between the core wire 10 of the cord 1 and the insulating coating tube 11 with the insulating tape 3 to ensure the insulating property. Further, since the insulating tape 3 is also directly wound around the core wire 10 at the connecting portion, an external force may be applied to the core wire 10 which is weak in strength and the core wire 10 may be cut. Moreover, when the core wire 10 is cut, the cut core wire 10 may break through the insulating tape 3, which may cause a short circuit.
【０００４】 そこで、作業性が良く、絶縁性が確実で、結線部分を保護することができる結 線絶縁保護チューブが開発された。この結線絶縁保護チューブは、絶縁性のかつ 熱収縮性のチューブ本体からなる。このチューブ本体中にコード１の芯線１０同 士を結合した結線部分を挿入圧入して、その結線部分を確実に絶縁しかつ保護す るものである。Therefore, a wire-insulating protective tube has been developed which has good workability, has a reliable insulating property, and can protect the wire-bonding portion. This connection insulation protection tube is composed of an insulating and heat-shrinkable tube body. The connecting portion, in which the core wire 10 of the cord 1 is connected, is inserted and press-fitted into this tube body to securely insulate and protect the connecting portion.
【０００５】 本考案は、上述の結線絶縁保護チューブの改良に係り、さらに確実に結線部分 を絶縁保護することができる結線絶縁保護チューブを提供することにある。The present invention relates to an improvement of the above-described wire insulation protection tube, and further provides a wire insulation protection tube capable of reliably insulating the wire connection portion.
【０００６】[0006]
本考案は、上記の目的を達成するために、コードの結線部分を外嵌するチュー ブ本体の内面に凸部を設けたことを特徴とする。 In order to achieve the above object, the present invention is characterized in that a convex portion is provided on the inner surface of the tube body to which the wire connecting portion of the cord is fitted.
【０００７】[0007]
本考案は、チューブ本体の内面に設けた凸部により、チューブ本体中に挿入し たコードの結線部分がそのチューブ本体から抜けるのを防ぐことができる。また 、上述のチューブ本体を透明乃至半透明となすことにより、上述の凸部がコード の結線部分をチューブ本体中に挿入する際の位置決めとなる。この結果、コード の結線部分をさらに確実に絶縁保護することができる。 According to the present invention, the convex portion provided on the inner surface of the tube body can prevent the connecting portion of the cord inserted into the tube body from coming off the tube body. Further, by making the above-mentioned tube body transparent or semi-transparent, the above-mentioned convex portion serves as positioning when inserting the wire connection portion of the cord into the tube body. As a result, the wire connection portion of the cord can be more reliably insulated and protected.

以下、本考案に係る結線絶縁保護チューブの一実施例を図１及び図２を参照し て説明する。図中、図３と同符号は同一のものを示す。 図において、４はチューブ本体である。このチューブ本体４は、例えば透明乃 至半透明の合成樹脂製からなり、絶縁性及び熱収縮性を有する。このチューブ本 体４は、一端側（左端側）の１本のコード１を挿入圧入する小径部４０と、他端 側（右端側）の複数本（図示の例では２本）のコード１を挿入圧入する大径部４ １とからなる。すなわち、小径部４０の内径は１本のコード１の絶縁被覆管１１ の外径とほぼ等しいか若干小さい。また、大径部４１の内径は２本のコード１を まとめた絶縁被覆管１１の外径とほぼ等しいか若干小さい。 このチューブ４本体の内周面に抜け止用の凸部４２と位置決め用の凸部４３と をそれぞれ一体に突設する。この抜け止用の凸部４２及び位置決め用の凸部４３ は、チューブ本体４の内周面に環状に設けても良いし、又は部分的に設けても良 い。なお、凸部４２を環状に設けた場合防水効果がある。 この抜け止用の凸部４２は、小径部４０側の端部に１個、大径部４１側の端部 に２個それぞれ設ける。なお、この抜け止用の凸部４２は、チューブ本体４の長 さに応じて、適宜個数設ける。また、位置決め用の凸部４３は、小径部４０と大 径部４１との間に２個、圧着端子２の長さ分の距離をおいて設ける。 An embodiment of the wire-insulating protective tube according to the present invention will be described below with reference to FIGS. 1 and 2. In the figure, the same symbols as those in FIG. 3 indicate the same components. In the figure, 4 is a tube body. The tube body 4 is made of, for example, a transparent or translucent synthetic resin, and has insulating properties and heat shrinkability. The tube main body 4 includes a small diameter portion 40 into which one cord 1 on one end side (left end side) is inserted and press-fitted, and a plurality of cords 1 (two cords in the illustrated example) on the other end side (right end side). It is composed of a large-diameter portion 41 which is inserted and press-fitted. That is, the inner diameter of the small diameter portion 40 is substantially equal to or slightly smaller than the outer diameter of the insulating coating tube 11 of one cord 1. Further, the inner diameter of the large diameter portion 41 is substantially equal to or slightly smaller than the outer diameter of the insulating coating tube 11 in which the two cords 1 are put together. On the inner peripheral surface of the main body of the tube 4, a retaining projection 42 and a positioning projection 43 are integrally projected. The retaining projection 42 and the positioning projection 43 may be annularly provided on the inner peripheral surface of the tube body 4 or may be partially provided. In addition, when the convex portion 42 is provided in an annular shape, it has a waterproof effect. One protrusion 42 for preventing the slip-out is provided at the end on the small diameter portion 40 side, and two at the end on the large diameter portion 41 side. It should be noted that the number of the protrusions 42 for preventing the slip-out is appropriately provided according to the length of the tube body 4. Further, two positioning convex portions 43 are provided between the small diameter portion 40 and the large diameter portion 41 with a distance corresponding to the length of the crimp terminal 2.
【０００９】 かくして、図１及び図２中の矢印に示すように、チューブ本体４の大径部４１ を結線部分の１本のコード１側から外嵌して、そのチューブ本体４の大径部４１ 中に２本のコード１側を挿入圧入し、かつそのチューブ本体４の小径部４０中に １本のコード１側を挿入圧入し、その結果３本のコード１の結線部分、すなわち ３本のコード１の端部の絶縁被覆管１１及び裸線の芯線１０及び圧着端子２をチ ューブ本体４で外嵌する。Thus, as shown by the arrows in FIGS. 1 and 2, the large diameter portion 41 of the tube body 4 is externally fitted from the one cord 1 side of the connecting portion, and the large diameter portion of the tube body 4 is fitted. Two cords 1 side are inserted and press-fitted into 41, and one cord 1 side is inserted and press-fitted into the small diameter portion 40 of the tube body 4, and as a result, three cord 1 connection parts, that is, three The insulation coating tube 11 at the end of the cord 1, the core wire 10 of the bare wire, and the crimp terminal 2 are externally fitted on the tube body 4.
【００１０】 このとき、チューブ本体４の小径部４０及び大径部４１の内面にそれぞれ設け た抜け止用凸部４２が、チューブ本体４の小径部４０及び大径部４１中にそれぞ れ挿入圧入した３本のコード１の絶縁被覆管１１に強く圧接するので、その３本 のコード１の結線部分が上述のチューブ本体４から抜けるのを防ぐことができる 。さらに、位置決め用の凸部４３が前記圧着端子２の両端に係合するので、上述 のコード１の結線部分が上述のチューブ本体４から抜けるのをさらに確実に防ぐ ことができる。 また、上述のチューブ本体４の小径部４０と大径部４１との間の内面に設けた 位置決め用の凸部４３が、コード１の結線部分をチューブ本体４中に挿入する際 の位置決めとなる。すなわち、２個の位置決め用の凸部４３が圧着端子２の両端 にそれぞれ位置したところで、チューブ本体４の小径部４０が１本のコード１の 絶縁被覆管１１の端部を密着外嵌し、かつチューブ本体４の大径部４１が２本の コード１の絶縁被覆管１１の端部を密着外嵌することとなる。 このように、この実施例における本考案の結線絶縁保護チューブは、コード１ の結線部分をさらに確実に絶縁保護することができる。At this time, the retaining projections 42 provided on the inner surfaces of the small diameter portion 40 and the large diameter portion 41 of the tube body 4 are inserted into the small diameter portion 40 and the large diameter portion 41 of the tube body 4, respectively. Since the insulation coating pipes 11 of the three cords 1 press-fitted are strongly pressed, it is possible to prevent the connecting portions of the three cords 1 from coming off from the tube body 4. Further, since the positioning convex portion 43 engages with both ends of the crimp terminal 2, it is possible to more reliably prevent the connecting portion of the cord 1 from coming off from the tube body 4. Further, the positioning convex portion 43 provided on the inner surface between the small diameter portion 40 and the large diameter portion 41 of the tube body 4 described above serves as positioning when the connecting portion of the cord 1 is inserted into the tube body 4. . That is, when the two positioning projections 43 are located at both ends of the crimp terminal 2, the small diameter portion 40 of the tube body 4 closely fits the end portion of the insulation coating tube 11 of one cord 1 onto the outside. Moreover, the large-diameter portion 41 of the tube body 4 closely fits the ends of the insulating coated pipes 11 of the two cords 1. As described above, the wire connection insulation protection tube of the present invention in this embodiment can further securely insulate and protect the wire connection portion of the cord 1.
【００１１】 しかも、チューブ本体４の小径部４０及び大径部４１の内面の抜け止用凸部４ ２がコード１の絶縁被覆管１１に強く圧接し、チューブ本体４がコード１の芯線 １０に直接当接しないので、外力がチューブ本体４を介してコード１の強度的に 弱い芯線１０に直接かからない。この結果、コード１の芯線１０の断線を防ぐこ とができ、かつ断線によるショートを防ぐことができ、コード１の結線部分の保 護を図ることができる。Moreover, the retaining projections 42 on the inner surfaces of the small-diameter portion 40 and the large-diameter portion 41 of the tube body 4 strongly press-contact with the insulating coating tube 11 of the cord 1, and the tube body 4 contacts the core wire 10 of the cord 1. Since they do not come into direct contact with each other, the external force is not directly applied to the core wire 10 of the cord 1 which is weak in strength via the tube body 4. As a result, disconnection of the core wire 10 of the cord 1 can be prevented, a short circuit due to disconnection can be prevented, and the connection portion of the cord 1 can be protected.
【００１２】 なお、上述の実施例においては、１本のコード１と２本（複数本）のコード１ とを結線したものを絶縁保護するものであるが、本考案は、１本のコードと１本 のコードとを結線したもの、あるいは複数本のコードと複数本のコードとを結線 したもの、を絶縁保護するものにも適用することができる。In the above-described embodiment, the one cord 1 and the two (plurality) cords 1 connected to each other are insulated and protected. However, the present invention uses one cord. It can also be applied to the one in which one cord is connected, or the one in which a plurality of cords and a plurality of cords are connected, for insulation protection.
【００１３】[0013]
以上から明らかなように、本考案の結線絶縁保護チューブは、チューブ本体の 内面に設けた凸部により、チューブ本体中に挿入したコードの結線部分がそのチ ューブ本体から抜けるのを防ぐことができる。また、上述のチューブ本体を透明 乃至半透明となすことにより、上述の凸部がコードの結線部分をチューブ本体中 に挿入する際の位置決めとなる。この結果、コードの結線部分をさらに確実に絶 縁保護することができる。 As is apparent from the above, the wire-insulating protective tube of the present invention can prevent the wire connecting portion of the cord inserted into the tube body from coming off from the tube body by the convex portion provided on the inner surface of the tube body. . Further, by making the above-mentioned tube body transparent or semi-transparent, the above-mentioned convex portion serves as positioning when inserting the wire connection portion of the cord into the tube body. As a result, the wire connection portion of the cord can be more reliably insulated and protected.
