【考案の詳細な説明】 〔産業上の利用分野〕 本考案は発変電所などにおける母線などの分岐に使用
するスプリング式クランプに関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a spring clamp used for branching a bus bar or the like in a power substation or the like.
従来のスプリング式クランプは第２図および第３図に
示すようなものであった。The conventional spring type clamp was as shown in FIG. 2 and FIG.
すなわち、１は本線、２は凹型で内面に本線１を嵌合

ルト部に螺着されたナットである。That is, 1 is a main line, 2 is a main body having a concave shape and a groove for fitting the main line 1 on the inner surface, 3 is a branch portion protruding from the outer surface of the main body 4, 4 is a branch line inserted and compressed in the branch portion 3, and 5 is a branch line. A box-shaped housing fitted to the main body 2, 6 is a saddle having a groove having a substantially T-shaped cross section and a bolt for fitting the main wire 1, and 7
Is a spring for pressing the saddle 6, and 8 is a nut screwed to the bolt portion of the saddle 6.
上記のようなスプリング式クランプを本線に取付ける

嵌合する。最後にナット８を緩めることによりサドル６
とスプリング７とで電線を押し付け固定する。To attach the above spring type clamp to the main line, proceed as follows. First, the branch line 4 is compression-connected to the branch part 3, and then the main line 1 is fitted into the groove provided in the main body 2. Next, the housing 5 containing the saddle 6 and the spring 7
After tightening the nut 8 screwed to the bolt portion of the saddle 6 to bring the spring 7 into the accommodated state, the nut is inserted into the main body 2 and fitted therein. Finally, by loosening the nut 8, the saddle 6
And the spring 7 press the wire and fix it.
〔考案が解決しようとする課題〕 上記のスプリング式クランプにおいて、電流は本線１
から本体２を通り、本体２の外面から突出した分岐部３
を通って分岐線４へ流れることになっている。[Problems to be Solved by the Invention] In the above spring type clamp, the current is 1
From the outer surface of the main body 2 through the main body 2 from the branch portion 3
It is supposed to flow to the branch line 4 through.
しかしながら、本線１を本体２に押し付けて固定する
ためのサドル６、スプリング７及びハウジング５はいず

リング７が発熱してへたるため、本線１と本体２間の抵
抗がさらに増大し、ついには本線１が破断するという問
題が生ずる。However, since the saddle 6, the spring 7 and the housing 5 for pressing and fixing the main line 1 to the main body 2 are all made of metal, there is a shunt of the current flowing through the main body 2 through them. Normally, since the electric resistance of the spring 7 is large, this shunt current is small, but if the surface treatment of the main line 1 is insufficient, or if the main line 1 becomes soiled or corroded due to long-term use, the main line 1 and the main body 2 will be separated. The electric resistance increases and the shunt current to the spring 7 increases. As a result, the spring 7 generates heat and sags, so that the resistance between the main line 1 and the main body 2 further increases, and finally the main line 1 breaks.

において、電線からスプリングを通って流れる電流の分
流回路が電気的に遮断されていることを特徴とする。The present invention provides a spring-type clamp that solves the above-mentioned problems. In a spring-type clamp in which an electric wire, a saddle and a spring are housed inside a main body and a housing, and the electric wire is pressed and fixed by the saddle and the spring. The shunt circuit for the current flowing from the electric wire through the spring is electrically cut off.

て、過熱により本線破断に至ることはなくなる。In the spring type clamp with the above structure,
The current shunt circuit consisting of the saddle-spring-housing-body-branch-branch line is cut off, so that the spring does not generate heat when energized. Therefore, even if the surface treatment of the main line is slightly insufficient or the resistance of the electrical contact surface between the main line and the main body increases due to deterioration, the spring does not sag and the main line pressing force is not lost in a short time. The main line will not be broken due to overheating.
以下、図面に示した実施例に基づいて本考案を説明す

到り、スプリング７には電流が流れない。FIG. 1 is a side view of an embodiment of a spring type clamp according to the present invention, in which 1 is a main line, 2 is a concave main body having a groove for fitting the main line 1 on an inner surface, and 3 is a protrusion from an outer surface of the main body 2. The branch part integrated with the main body, 4 is a branch line inserted into the branch part 3 and compressed, 5 is a box-shaped housing fitted to the main body 2, 6 is a substantially T-shaped cross section, and the main line 1 is fitted A saddle having a groove and a bolt portion, 7 is a spring that presses the main wire 1 against the main body 2 through the saddle 6, and 8 is a nut screwed to the bolt portion of the saddle 6, which is used when mounting the device, and is usually Removed. Reference numeral 9 is an insulating plate that electrically insulates between the spring 7 and the housing 5. In the spring type clamp having such a structure, since the spring 7 and the housing 5 are electrically insulated, the shunted current flows from the main line 1 through the saddle 6 and the housing 5 to the main body, and then to the spring 7. Does not flow current.

がなくなり、スプリングには電流が流れない。The present invention is not limited to the above embodiment, an insulating plate may be inserted between the saddle and the spring, and even if the spring itself is coated with an insulating material, the current can be prevented from flowing through the spring. . Further, if the saddle or the housing is made of an insulating material, the shunting itself disappears and no current flows through the spring.
以上説明したように本考案によれば、電線からスプリ

止できるという優れた効果がある。As described above, according to the present invention, since the shunt circuit for the current flowing from the wire through the spring is electrically cut off, the current does not flow in the spring, and the electric contact surface between the wire and the main body should be prevented. Insufficient treatment, pollution due to long-term use,
Even if the electric resistance between the electric wire and the main body increases due to corrosion or the like, there is an excellent effect that it is possible to prevent a main line breakage accident due to sudden abnormal heating in a short time.
