本考案は、フリーセンター型クランプの改良に
関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a free center type clamp.
フリーセンター型クランプは線溝内に電線を収
納するとともに、ストラツプまたはアダプターが
碍子連などに連結された連結金具に連結される。
そこで、クランプ本体のクレビス部とストラツプ
とは連結軸で連結されているが、その先端はクレ
ビス部の外面より突出するとコロナが発生するた
め外側へ突出させることはできず、また連結軸の
抜け止めのための割りピンなどもコロナ発生の原
因となるため使うことはできなかつた。 A free center type clamp stores the electric wire in the wire groove, and the strap or adapter is connected to a connecting fitting connected to an insulator chain or the like.
Therefore, the clevis part of the clamp body and the strap are connected by a connecting shaft, but if the tip protrudes beyond the outer surface of the clevis part, corona will be generated, so it cannot be made to protrude outward, and it also prevents the connecting shaft from coming off. Cotter pins could not be used as they could cause the spread of coronavirus.
そのため、従来は第１図に示すように連結軸ａ
の抜け止めのためにクランプ本体ｂのクレビス部
ｃから連結軸ａに止めビスｄを螺合させていた。
ところが風圧による横振れや振動でクランプ本体
ｂやストラツプｅは連結軸ａが軸となつて回転す
るが連結軸ａは止めビスｄによつて固定されてい
るため回転できないから、荷重が止めビスｄに加
わり、その結果止めビスｄがせんだんすることが
あつた。また、ストラツプｅの回転によつて連結
軸ａの一部分のみが摩耗するという欠点があつ
た。またクランプが規格値以上の荷重により破壊
する場合は、決まつた所で破壊することがクラン
プの強度に対する安定性から望ましいが、従来の
クランプではクレビス部のビス穴に応力が集中す
る結果、所定の破壊個所の他にクレビス部も破壊
することがあり、破壊個所が安定せず、強度が不
安定になるという欠点があつた。 Therefore, conventionally, as shown in Fig. 1, the connecting shaft a
In order to prevent this from coming off, a set screw d is screwed into the connecting shaft a from the clevis c of the clamp body b.
However, due to lateral vibration and vibration caused by wind pressure, the clamp body b and the strap e rotate around the connecting shaft a, but since the connecting shaft a is fixed by the set screw d and cannot rotate, the load is transferred to the set screw d. As a result, the locking screw d sometimes slipped. Another drawback was that only a portion of the connecting shaft a was worn out due to the rotation of the strap e. In addition, if a clamp breaks due to a load exceeding the standard value, it is desirable for the clamp to break at a predetermined location from the viewpoint of stability with respect to the strength of the clamp. In addition to the fractured part, the clevis part may also be fractured, which has the disadvantage that the fractured part is not stable and the strength is unstable.
また、第１図の他に、実開昭55−62130号公報
に記載されている従来技術もあるが、これは連結
軸に止めビスの突出端部を遊嵌する環状溝を設け
るものであるから、この環状溝の隅部に応力の集
中が発生するという欠点があつた。 In addition to Fig. 1, there is also a conventional technique described in Japanese Utility Model Application Publication No. 55-62130, in which an annular groove is provided in the connecting shaft into which the protruding end of the set screw is loosely fitted. Therefore, there was a drawback that stress concentration occurred at the corners of this annular groove.
本考案は、このような欠点を解決するために考
案したもので、フリーセンター型クランプ本体と

に、フリーセンター型クランプの強度の安定化を
はかることを目的とするものである。 The present invention was devised to solve these drawbacks, and aims to prevent uneven wear of the connecting shaft between the free center type clamp body and the strap, and to stabilize the strength of the free center type clamp. This is the purpose.

である。 Embodiments of the present invention will be described below with reference to FIGS. 2 and 3. In the figure, 1 is a free center type clamp body, 1a is a clevis part provided on both sides, and 2
is a presser metal fitting, 3 is a bolt for fastening the presser metal fitting 2 to the clamp body 1, 4 is a washer, 5 is a nut,
6 is a strap, 7 is a connecting shaft for connecting the lower end of the strap 6 to the clevis portion 1a of the clamp body 1, 8 is an adapter inserted between the upper ends of the straps 6, and 9 is an insulator connecting adapter 8. (not shown) etc., and 10 is a nut.

けないようにする。 In the present invention, as shown in FIG. 2, a collar 7a is provided on the head of the connecting shaft 7, and the connecting shaft 7 is inserted from inside the clevis portion 1a of the clamp body 1 into which the lower end of the strap 6 is fitted. Clamp body 1
and the strap 6 are rotatably connected, and
A pin (or screw) 11 is erected on the clamp body 1 close to the head 7a of the connecting shaft 7 to prevent the connecting shaft 7 from coming off.

にする。 FIG. 3 shows another embodiment of the present invention, in which projections 2a are provided on both sides of the presser metal fitting 2, and the projections 2a prevent the connecting shaft 7 from coming off.

果がある。 Since the present invention is as described above, when the connecting shaft 7 starts to come off, the retaining pin 11 and the protrusion 2 of the presser metal fitting 2
The head 7a of the connecting shaft 7 hits the point a, and the connecting shaft 7 will not come off. In addition, since the connecting shaft 7 of the present invention is rotatable, the contact between the clevis portion 1a of the clamp body 1 and the strap 6 and the connecting shaft 7 is not at one place, so that only a portion of the connecting shaft is contacted as in the conventional case. There is no risk of uneven wear. Further, since no stress concentration occurs on the clevis portion 1a of the clamp body 1, breakage caused by this is eliminated, and the breakage location of the clamp is stabilized. Further, the machining required for screwing the set screw onto the connecting shaft is also unnecessary. Furthermore, unlike the device described in Japanese Utility Model Application Publication No. 55-62130, the present invention does not have an annular groove in which the protruding end of the set screw is loosely fitted into the connecting shaft, so there is no risk of stress concentration, etc. This invention has many effects.
