JP-A-8-287979

しかしながら、特許文献１はインシュロックのベルト体によって、通電部分を上から押さえて固定するものであり、インシュロックには通電の機能はない。このため、通電部分は別途に設ける必要があり、通電部分を施工するための施工作業が別途に必要になる。 However, in Patent Document 1, an energized portion is pressed and fixed from above by an insulating belt member, and the insulating lock does not have an energizing function. For this reason, it is necessary to provide an energization part separately, and the construction work for constructing an energization part is needed separately.

この発明は、以上の問題点を解決するために、通電部分を別途に設ける必要がなく、さらには、通電のための施工作業が別途に必要でなく、安定した通電構造を得られる通電用インシュロックを提供することを目的とする。 In order to solve the above-described problems, the present invention does not require a separate energization portion, and further does not require a separate construction work for energization, and can provide a stable energization structure. The purpose is to provide.

以上の課題を解決するために、第一発明は、ベース部と、このベース部から延設される可撓性のベルト体と、このベルト体に所定ピッチで形成される複数の係止突起と、前記ベース部に形成されて前記ベルト体の先端が挿通される挿通孔と、この挿通孔の内部又は縁部に形成されて前記係止突起が係止する係止部と、を有することで、前記ベルト体を前記挿通孔に通してループ状にし電線を結束できるインシュロックにおいて、前記ベース部に、複数の前記結束された電線を通電させる金属部を備えたことを特徴とする通電用インシュロックである。 In order to solve the above-described problems, a first invention includes a base portion, a flexible belt body extending from the base portion, and a plurality of locking protrusions formed on the belt body at a predetermined pitch. An insertion hole formed in the base portion through which the tip of the belt body is inserted, and a locking portion formed in or on the edge of the insertion hole and locked by the locking protrusion. An insulating lock that can pass the belt body through the insertion hole into a loop shape to bind electric wires, wherein the base portion is provided with a metal portion that supplies electric power to the plurality of electric wires that are bound. is there.

第二発明は、さらに、前記金属部は、電線の被服を貫通するに十分なほど先端が鋭利な突起を形成することを特徴とする通電用インシュロックである。
第三発明は、さらに、前記突起は、円錐、または多角錐であることを特徴とする通電用インシュロックである。 According to a second aspect of the present invention, there is provided an energizing insulation lock characterized in that the metal portion has a protrusion with a sharp tip sufficient to penetrate the clothing of the electric wire.
According to a third aspect of the present invention, there is provided an energizing insulation lock, wherein the protrusion is a cone or a polygonal pyramid.

第一発明によれば、複数の電線の通電部分を露出させ、この露出部分に、ベース部の金属部を接触させた状態で、ベルト体による結束を行えば、通電部分を別途に設けなくても、安定した通電構造を得られる。
第二発明によれば、複数の電線をそのままの状態で、ベルト体による結束を行えば、金属部の突起が強く電線に押圧され、この突起が電線の被服を貫通するので、通電部分を別途に設けなくても、さらには、通電部分を露出させるなどの通電のための施工作業を行わなくても、安定した通電構造を得られる。 According to the first aspect of the present invention, if the conductive portion of the plurality of electric wires is exposed, and the belt portion is bound with the exposed portion in contact with the metal portion of the base portion, the conductive portion need not be provided separately. In addition, a stable energization structure can be obtained.
According to the second invention, when the plurality of electric wires are left as they are and bound by the belt body, the protrusion of the metal part is strongly pressed against the electric wire, and this protrusion penetrates the clothes of the electric wire. Even if it does not provide, even if it does not perform construction work for energization, such as exposing an energization part, a stable energization structure can be obtained.

この発明の実施形態を、図１及び図２に示す。
樹脂製のベース部１は略立方体形状をなし、このベース部１の上面３の端から一体的に可撓性のベルト体５が延設される。このベルト体５の片面７、すなわちベース部１に対抗する面には、所定ピッチで複数の係止突起９が、波状に形成される。各係止突起９の断面は、垂直面を有する直角三角形である。 An embodiment of the present invention is shown in FIGS.
The base portion 1 made of resin has a substantially cubic shape, and a flexible belt body 5 is integrally extended from the end of the upper surface 3 of the base portion 1. A plurality of locking projections 9 are formed in a wave shape at a predetermined pitch on one surface 7 of the belt body 5, that is, the surface facing the base portion 1. The cross section of each locking projection 9 is a right triangle having a vertical surface.

ベース部１の上面３には、前記ベルト体５が延設される端とは反対側の端に、このベルト体５の先端が挿通される挿通孔１１が形成される。この挿通孔１１の内部には、挿通孔１１の内壁に沿ってベルト体５の係止突起９が係止する係止部１３が、複数形成される。この複数の係止部１３は、ベルト体５の係止突起９の波状とは、反対向きの形状を有する波状となっている。 In the upper surface 3 of the base portion 1, an insertion hole 11 through which the tip of the belt body 5 is inserted is formed at the end opposite to the end where the belt body 5 is extended. Inside the insertion hole 11, a plurality of locking portions 13 are formed along which the locking protrusions 9 of the belt body 5 are locked along the inner wall of the insertion hole 11. The plurality of locking portions 13 have a wave shape having a shape opposite to the wave shape of the locking protrusion 9 of the belt body 5.

これにより、ベルト体５に引き抜く力がかかったときに、両波状の部分は、垂直面でしっかり係止する。のみならず、ベルト体５が挿通される方向に力がかかったときは、波状の直角三角形の斜辺に相当する斜面で、両波状の部分は滑り、容易に挿通がなされる。
ベルト体５は挿通孔１１に挿通されることでループ状になり、このループ状の部分で、電線１５を強く結束できる。 Thereby, when the pulling-out force is applied to the belt body 5, both wave-like portions are firmly locked on the vertical surface. In addition, when a force is applied in the direction in which the belt body 5 is inserted, both the wavy portions slide on the inclined surface corresponding to the hypotenuse of the wavy right triangle, and are easily inserted.
The belt body 5 is looped by being inserted into the insertion hole 11, and the electric wire 15 can be strongly bound at the loop-shaped portion.

そして、ベース部１の上面３には、導電性を有する金属部１７により複数の突起１９が形成される。各突起１９は、円錐の形状を有し、電線１５のビニールなどの被服１５Ａを貫通するに十分なほど先端が鋭利に形成される。また、各突起１９は、金属部１７の板状部分２１の上に形成され、よって底部の部分が連続しているので、互いに通電する。 A plurality of protrusions 19 are formed on the upper surface 3 of the base portion 1 by the conductive metal portion 17. Each protrusion 19 has a conical shape, and the tip is sharply formed enough to penetrate the clothes 15 A such as vinyl of the electric wire 15. In addition, each protrusion 19 is formed on the plate-like portion 21 of the metal portion 17, and thus the bottom portion is continuous, so that they are energized with each other.

「実施形態の効果」
この実施形態によれば、複数の電線１５、通常は２本の電線１５を、被服１５Ａで覆われた通常のままの状態で、ループ状のベルト体５に通し、ベルト体５の先端を挿通孔１１の反対側から引っ張れば、ベルト体５により２本の電線１５は強く結束され、同時に、金属部１７の突起１９が強く電線１５に押圧される。この押圧により、突起１９が電線１５の被服１５Ａを貫通するので、電線１５の内部の金属１５Ｂに強く接触する。また、この強い接触は、ベルト体５により耐久性を有して、維持される。 "Effect of the embodiment"
According to this embodiment, a plurality of electric wires 15, usually two electric wires 15, are passed through the loop-shaped belt body 5 in the normal state covered with the clothing 15 A, and the tip of the belt body 5 is inserted. When pulled from the opposite side of the hole 11, the two electric wires 15 are strongly bound by the belt body 5, and at the same time, the protrusion 19 of the metal portion 17 is strongly pressed against the electric wire 15. Due to this pressing, the protrusion 19 penetrates the clothing 15 A of the electric wire 15, so that it strongly contacts the metal 15 B inside the electric wire 15. Moreover, this strong contact has durability with the belt body 5 and is maintained.

電線１５の金属１５Ｂは、銅製であること、あるいは細線の束であること、などから柔らかな性質を有するので、鋭利な突起１９は、この電線１５の金属１５Ｂにまで容易に貫通し、食い込んで、しっかり電通を確保する。
このため、通電部分を別途に設けなくてもよい。さらには、通電部分を露出させるなどの通電のための施工作業を行わなくてもよい。そして、インシュロックの耐久性により、安定した通電構造を得られる。 Since the metal 15B of the electric wire 15 is made of copper or is a bundle of fine wires, it has a soft property. Therefore, the sharp protrusion 19 can easily penetrate and bite into the metal 15B of the electric wire 15. Secure the Dentsu.
For this reason, it is not necessary to provide an electricity supply part separately. Furthermore, it is not necessary to perform construction work for energization such as exposing the energized portion. A stable energization structure can be obtained due to the durability of the insulation lock.

「他の実施形態」
以上の実施形態では、金属部分の突起１９は、円錐形状であったが、他の実施形態では、他の形状、たとえば多角錐であっても良い。貫通性を高めるために、針状にすることも可能である。 "Other embodiments"
In the above embodiment, the protrusion 19 of the metal portion has a conical shape, but in other embodiments, it may have another shape, for example, a polygonal pyramid. In order to improve penetrability, it is also possible to make it needle-shaped.

以上の実施形態では、通電を行う金属部１７は、電線１５の被服１５Ａを貫通するに十分なほど先端が鋭利な突起１９を形成するものであったが、他の実施形態では、貫通する突起１９を形成せず、複数の電線１５の通電部分を露出させ、この露出部分に、ベース部１の金属部１７を接触させた状態で、ベルト体５による結束を行うこともできる。この場合には、貫通はないので、通電部分を露出させるなどの作業は必要であるが、通電部分を別途に設けなくても良いという効果を得られる。また、インシュロックの耐久性により、安定した通電構造を得られる。 In the above embodiment, the metal part 17 that conducts electricity forms the protrusion 19 having a sharp tip enough to penetrate the clothing 15A of the electric wire 15, but in other embodiments, the protrusion that penetrates. It is also possible to perform the bundling by the belt body 5 in a state where the energized portions of the plurality of electric wires 15 are exposed without forming 19 and the metal portion 17 of the base portion 1 is in contact with the exposed portions. In this case, since there is no penetration, an operation such as exposing the energized portion is necessary, but there is an effect that it is not necessary to separately provide the energized portion. Further, a stable energization structure can be obtained due to the durability of the insulation lock.
