挿入する構造の改良に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in the structure of a conduit terminal member of a control cable used for remotely controlling a driven device by an operating means in various industrial equipment. More specifically, the present invention relates to an improvement in a structure in which a washer is inserted into the bottom of a conduit insertion hole of a conduit end member of a control cable.
［従来技術］
コントロールケーブル（以下単にケーブルとい

えて遠隔操作を行うのに用いられる。[Prior Art] A control cable (hereinafter simply referred to as a cable) generally consists of a flexible conduit and an inner cable slidably inserted into the conduit, and an operating means connected to one end of the inner cable. It is used to perform remote control by transmitting the push or pull force of the cable to the driven device connected to the other end of the inner cable.
かかる一方の操作力を他方に正確に伝えるため
導管の夫々の端部は操作手段側付近と、従動機器
側付近に固定しなければならない。 In order to accurately transmit such operating force from one to the other, each end of the conduit must be fixed near the operating means side and near the driven device side.
このような端末部材は、第２図で示したように
一方に導管１を挿入固着するための導管挿入孔４
と、これに連設され他方に貫通した内索挿通孔５
が設けられており、前記導管挿入孔４と、内索挿
通孔５との境目が底部６となつており、該底部６
は、一般に切削工具の関係上第２図で示している
ように擂鉢形になつているのが普通である。 Such an end member has a conduit insertion hole 4 for inserting and fixing the conduit 1 into one side as shown in FIG.
and an inner cable insertion hole 5 which is connected to this and penetrates through the other.
The boundary between the conduit insertion hole 4 and the inner cable insertion hole 5 is a bottom portion 6.
Due to the nature of the cutting tool, it is generally shaped like a mortar, as shown in Figure 2.
［考案が解決しようとする問題点］
上述のような導管の端末構造においては、特に
引き操作が行われた場合、導管にはＡ方向の圧縮
の力が加わるために、固定されている端末部材３
の擂鉢形の底部６に、フラツトに切断された導管
１を構成する螺旋管２の端部が強力に押し付けら
れるので、比較的短期間で底部６の擂鉢形状に沿
つて螺旋管２の端部が変形を始め、最後には二点
破線で示した内索８に当接するようになり、内索
の円滑な摺動を阻害する原因となつている。[Problems to be solved by the invention] In the conduit terminal structure as described above, especially when a pulling operation is performed, compressive force in the A direction is applied to the conduit, so that the fixed terminal member 3
Since the end of the helical tube 2 constituting the flat-cut conduit 1 is strongly pressed against the mortar-shaped bottom 6, the end of the helical tube 2 will be cut along the mortar-shaped bottom 6 in a relatively short period of time. begins to deform, and eventually comes into contact with the inner cable 8 shown by the two-dot broken line, causing a disturbance in the smooth sliding of the inner cable.
かかる従来の欠点に鑑み、第３図で示したよう
に底部６に平ワツシヤ９を挿入し、フラツトな導
管の端部をワツシヤのフラツトな面で受けるよう
にしたり、又図示しないが底部をフラツトな形状

第４図で示したように導管１に加わるＡ方向の圧
力によつて螺旋管の端部が半径方向内向きに変形
し、やがて内索８に当接して内索の円滑な摺動を
阻害することは避けられなかつた。 In view of these conventional drawbacks, as shown in FIG. 3, a flat washer 9 is inserted into the bottom 6 so that the flat end of the conduit is received by the flat surface of the washer, or the bottom is made flat (not shown). However, as shown in Fig. 4, the end of the spiral tube deforms inward in the radial direction due to the pressure in the A direction applied to the conduit 1, and eventually It was inevitable that it would come into contact with the inner cable 8 and impede smooth sliding of the inner cable.

されている。[Means for solving the problems] The structure of the cable conduit terminal member of the present invention is as follows:
A conduit end member that is cylindrical and has a conduit insertion hole bored in one side for inserting and fixing the conduit, and an inner cable insertion hole connected to the conduit insertion hole and passed through the other side. In this method, a structure is adopted in which an inverted mortar-shaped washer is fitted into the bottom of the conduit insertion hole.
［作用］
本考案のケーブルの導管用端末部材に於いては
導管挿入孔の底部に、逆擂鉢形のワツシヤーを挿

方向に力が加わるので半径方向内向きには変形し
ないようになつている。[Function] In the cable conduit terminal member of the present invention, an inverted mortar-shaped washer is inserted into the bottom of the conduit insertion hole, so that compressive force is not applied to the end of the conduit that is in contact with the bottom. When a force is applied to the end portion of the spiral tube, the force is applied in a direction in which the end portion of the spiral tube expands radially outward according to the shape of the washer, so that it is not deformed radially inwardly.
［実施例］
つぎに図面を参照しながら本考案のケーブルの
導管用端末部材の構造について説明する。[Example] Next, the structure of the cable conduit terminal member of the present invention will be described with reference to the drawings.
第１図は、本考案の一実施例を示す要部の一部

が設けられている。 FIG. 1 is a partially cutaway side view of the main parts showing an embodiment of the present invention (the same parts as the conventional example are
Assign the same number. ) 1 is a conduit, which is composed of a spiral tube 2 made of a spirally wound metal plate; 3 is an end member, and one side has a conduit insertion hole 4;
An inverted mortar-shaped washer 9a is fitted into the bottom 6 of the conduit insertion hole 4, and an inner cable insertion hole 5 is connected to the bottom 6 and penetrated through the other side.
is provided.
かかる構造の端末部材３は一般に、操作手段側

に強く押圧されるが、ワツシヤ９ａは逆擂鉢形に
なつているため、螺旋管の端部はワツシヤの逆擂
鉢形の形状に沿つて半径方向外向きに拡がろうと

向きには変形することがなく、従つて内索の円滑
な摺動を阻害することがない。 The terminal member 3 having such a structure is generally fixed near the operating means side or near the driven equipment side and the cable is routed, and when the inner cable is pulled by the operating means, the terminal member 3 in FIG. Since a force in the direction A is applied to the conduit 1 with respect to the member 3, the end of the spiral tube 2 is attached to the washer 9a fitted into the bottom 6.
However, since the washer 9a has an inverted mortar shape, a force acts on the end of the spiral tube to expand radially outward along the inverted mortar shape of the washer. The end of the helical tube does not deform inward in the radial direction, and therefore does not impede smooth sliding of the inner cable.
