Description
【0001】[0001]
本考案は、ケーシング内に電気機器を配備した車両用自動変速機のような密封 型電気装置において、内外を接続する導電線のシール構造の改良に関するもので ある。 The present invention relates to an improvement in a seal structure of a conductive wire that connects the inside and the outside of a sealed electric device such as an automatic transmission for a vehicle in which an electric device is arranged in a casing.

従来、この種の導電線のシール構造としては、実開昭60−183532号や 実開昭63−20317号の各公報に係る技術のように、導電線の途中の皮膜を 剥離し、この部分に半田を流し込むことにより、導電線内の芯線間等の空隙を遮 断する構成である。これにより、導電線内の密封効果が向上する。 Conventionally, as a sealing structure for this type of conductive wire, as in the techniques disclosed in Japanese Utility Model Publication No. 60-183532 and Japanese Utility Model Publication No. 63-20317, the coating in the middle of the conductive wire is peeled off and this portion is removed. By pouring the solder into, the gap between the core wires in the conductive wire is blocked. This improves the sealing effect in the conductive wire.

しかしながら、導電線の途中における皮膜を単に剥離しただけでは、芯線間の 空隙に粘性の高いエポキシ樹脂等の樹脂溶液が浸透せず、空隙が残ってシール効 果が低下するため、上記従来技術のごとく半田を流し込む作業を必要としていた 。 本考案は、上記問題点に鑑み考案したものであり、容易に導電線内の密封作業 が可能な、導電線のシール構造を提供することを目的とする。 However, simply peeling off the film in the middle of the conductive wire does not allow the resin solution such as highly viscous epoxy resin to penetrate into the voids between the core wires, leaving voids and reducing the sealing effect. It required the work of pouring in the solder. The present invention has been made in view of the above problems, and an object of the present invention is to provide a conductive wire sealing structure capable of easily performing a sealing operation in a conductive wire.

本考案は上記目的を達成するために、密封型電気装置の内外を接続する導電線 の皮膜の一部を剥離して露出した芯線の撚り戻し部と、該撚り戻し部を密封した シール部とを具備したことを特徴とする導電線のシール構造を構成する。 In order to achieve the above object, the present invention provides a twisted-back portion of a core wire that is exposed by peeling off a part of a coating of a conductive wire that connects the inside and outside of a sealed electric device, and a seal portion that seals the twisted-back portion. A seal structure of a conductive wire is provided.

本考案に係る好適な一実施例を、添付図面に基づき詳述する。 図1は、車両の自動変速機に適用した実施例であり、自動変速機のケーシング 1に電気接続装置を取付けた状態を示す。電気接続装置のボディ2は略円筒状の 形状をしており、ケーシング1の穴1aに嵌合可能な円筒状のはめ合い部2aは 、シール用のOリング3を配置するための環状の溝2bを有している。また、ボ ディ2は図1において右端部側に4本の脚部2cを有しており、脚部2cの先端 にストッパ部2dを設けている。ストッパ部2dの外径部はケーシング1の穴1 aへの挿入を容易にするためにテーパ面としてある。また、ボディ2の図1中左 端部側にボディ2の挿入方向へのストッパとなるストッパ部2eを設けている。 ボディ2の内径部に小径部2fを設けており、この小径部2fは、これに嵌合す ると共に段差部2gによって停止するよう拡径部付きの円柱状の弾性部材4を設 けている。弾性部材4は、これを軸方向に貫通する複数の貫通穴4aを設けてお り、この貫通穴4aの端部に、弾性部材4の端面4bまで延びる拡大した大径部 4cを形成している。 A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment applied to an automatic transmission of a vehicle, and shows a state in which an electric connection device is attached to a casing 1 of the automatic transmission. The body 2 of the electrical connection device has a substantially cylindrical shape, and the cylindrical fitting portion 2a that can be fitted into the hole 1a of the casing 1 is an annular groove for arranging the O-ring 3 for sealing. 2b. The body 2 has four leg portions 2c on the right end side in FIG. 1, and a stopper portion 2d is provided at the tip of the leg portion 2c. The outer diameter portion of the stopper portion 2d has a tapered surface to facilitate insertion into the hole 1a of the casing 1. Further, a stopper portion 2e serving as a stopper in the insertion direction of the body 2 is provided on the left end side of the body 2 in FIG. A small diameter portion 2f is provided on the inner diameter portion of the body 2, and the small diameter portion 2f is provided with a columnar elastic member 4 with a diameter increasing portion so as to be fitted into the small diameter portion 2f and stopped by the step portion 2g. . The elastic member 4 is provided with a plurality of through holes 4a penetrating the elastic member 4 in the axial direction, and an enlarged large diameter portion 4c extending to the end surface 4b of the elastic member 4 is formed at the end of the through hole 4a. There is.
【0006】 各貫通穴4aは、ケーシング1の内外を接続する導電線5を密着状態で挿通し ている。この導電線5は、耐熱性及び耐油性を有し、図2で示すように多数の芯 線5aを皮膜5bで被覆している。そして、導電線5は、一端をケーシング1内 部のソレノイドなどの電気機器(図示せず)と接続し、他端をケーシング1外部 のコントロールユニットなどの制御機器(図示せず)と接続する。なお、複数の 導電線5は束ねた状態で樹脂管6内に配置する。Each of the through holes 4 a has a conductive wire 5 that connects the inside and the outside of the casing 1 inserted therein in a close contact manner. This conductive wire 5 has heat resistance and oil resistance, and as shown in FIG. 2, a large number of core wires 5a are covered with a film 5b. The conductive wire 5 has one end connected to an electric device (not shown) such as a solenoid inside the casing 1, and the other end connected to a control device (not shown) such as a control unit outside the casing 1. The plurality of conductive wires 5 are arranged in the resin pipe 6 in a bundled state.
【0007】 導電線5は、貫通穴4aの大径部4c内において、皮膜5bの一部を剥離した 剥離部5cから芯線5aを露出させ、該芯線5aを図1及び図2で示すごとく長 さ方向に撚り戻して撚り戻し部5dを形成している。該撚り戻し部5dに於いて 、各芯線5a間の空隙は大きく広がり、後述するシール部7の樹脂溶液が上記芯 線5a間の空隙に万遍無く行き渡る。このため、シール部7の樹脂溶液が硬化し た後はケーシング1内部の油などが、導電線5内を浸透して外部に漏洩しない。 また、該撚り戻し部5dは図1で示す大径部4cの段差面と当接することにより 、導電線5の長さ方向の位置決めの機能を有する。In the conductive wire 5, the core wire 5a is exposed from the peeled portion 5c where a part of the film 5b is peeled off in the large diameter portion 4c of the through hole 4a, and the core wire 5a is elongated as shown in FIGS. 1 and 2. The untwisted portion 5d is formed by untwisting in the vertical direction. In the untwisted portion 5d, the voids between the core wires 5a greatly expand, and the resin solution of the seal portion 7 described later spreads evenly over the voids between the core wires 5a. Therefore, after the resin solution in the seal portion 7 is hardened, oil or the like in the casing 1 does not penetrate into the conductive wire 5 and leak to the outside. Further, the untwisted portion 5d has a function of positioning the conductive wire 5 in the longitudinal direction by abutting on the step surface of the large diameter portion 4c shown in FIG.
【0008】 ボディ2内及び大径部4c内は、エポキシ樹脂などの樹脂溶液を注入しかつ硬 化させることによりシール部7を形成し、密封している。これに伴い、前記した ごとく導電線5の撚り戻し部5cも、シール部7で密封されている。A seal portion 7 is formed and sealed in the body 2 and the large diameter portion 4 c by injecting a resin solution such as an epoxy resin and hardening the resin solution. Along with this, the untwisted portion 5c of the conductive wire 5 is also sealed by the seal portion 7 as described above.

以上詳述したように本考案の構成によれば、導電線の皮膜の一部を剥離して露 出した芯線を撚り戻し、該撚り戻し部をシール部で密封するだけで、半田を流し 込む作業や圧着部品のごとき余計な部品を必要とせず、極めて容易に導電線内を 密封することができる。 As described in detail above, according to the configuration of the present invention, the solder is poured by simply peeling off a part of the film of the conductive wire and untwisting the exposed core wire and sealing the untwisted portion with the seal portion. It is possible to seal the inside of the conductive wire very easily without the need for work and extra parts such as crimp parts.
