本考案は開閉器等に使用されている締付端子装置の改良
に関する。[Detailed Description of the Invention] The present invention relates to an improvement of a clamping terminal device used in a switch or the like.
この種の従来装置は、開閉器等の接続端子台に端子を重

具で保持しながらナツトを他の工具で徐々に締付は操作
しなければ不便であり、特に高所における作業等ではボ
ルト等を落すことが多分にある。This type of conventional device overlaps the terminals on the connection terminal block of a switch, etc., inserts the bolt into both, and then tightens the bolt using a tool to prevent the head of the bolt from rotating. It is inconvenient to tighten the nut gradually with another tool while holding it with the bolt, and bolts and the like are often dropped, especially when working in high places.
本考案はこれらの点に鑑み、ボルトの廻り止めと、脱落
防止の機能を一体的に形成した締付端子装置を提供せん
とするものである。In view of these points, the present invention aims to provide a tightening terminal device that integrally functions to prevent the bolt from rotating and to prevent it from falling off.
以下本考案実施例を図面にもとづき説明する。Embodiments of the present invention will be described below based on the drawings.
図において、１は開閉器等のブッシング、２は開閉器の

接続端子台、３は外部導線３ａの端末に設けられた端子
で廻り止め金具４を介して複数のボルト５およびナツト
６により前記接続端子台２にねし止めされる。In the figure, 1 is a bushing of a switch, etc., 2 is a connection terminal block that penetrates the bushing 1 from inside the switch and is pulled out to the outside, and 3 is a terminal provided at the end of an external conductor 3a, and a rotation stopper 4 It is screwed to the connection terminal block 2 via a plurality of bolts 5 and nuts 6.
この廻り止め金具４は第２図に示すように略々口字形状

転を防止する角孔４ｂを穿設し、また、両端に舌片４Ｃ
を設はコ字状に折り曲げ、その先端は前記角孔４ｂを覆
うように延長される。As shown in FIG. 2, this rotation stopper 4 has a substantially square shape, and has a square hole 4b in the horizontal part 4a that fits into the head of the tightening bolt 5 to prevent rotation. , tongue piece 4C on both ends
is bent into a U-shape, and its tip is extended to cover the square hole 4b.
水平部４ａと舌片４Ｃとの距離はボルト５の頭の高さに
略々一致させ、ボルト５の頭を抑え脱落を防止するよう
にする。The distance between the horizontal portion 4a and the tongue piece 4C is made to approximately match the height of the head of the bolt 5 to suppress the head of the bolt 5 and prevent it from falling off.
さらに、廻り止め金具４の略中央部に穴４ｄを穿設し、
前記接続端子台２にねじ７にて取付ける。Furthermore, a hole 4d is bored approximately in the center of the rotation stopper 4,
Attach to the connection terminal block 2 using screws 7.
本考案は以上のように廻り止め金具にボルトの頭部が挿
入できる角孔を設けることにより、ボルトの回動を防止
し、さらに、両端部を折り曲げて形成した舌片にてボル
トの脱落も防止でき、締付は作業時にはボルト側を保持
することなく、単にナツト側のみを回動すればよいので
、その締付は作業が極めて容易にでき、しかもこのよう
なことによって緩み止めの効果があり、緩みによる発熱
現象を防止できる。As described above, this invention prevents the bolt from rotating by providing a square hole in the rotation stopper into which the head of the bolt can be inserted, and also prevents the bolt from falling off with the tongue pieces formed by bending both ends. This makes tightening work extremely easy, as you only have to turn the nut side without holding the bolt side during tightening work, and this also increases the loosening prevention effect. This prevents heat generation due to loosening.
さらに、この装置を柱上用開閉器等に用いれば、高所で
の作業が極めて容易でボルトを落すようなことがなく作
業能率を向上することができる。Furthermore, if this device is used in a pole-mounted switch or the like, it is extremely easy to work at high places, and the work efficiency can be improved without dropping bolts.
