ドを使用した比例制御弁に関するものである。[Detailed description of the invention] This invention is an electrically operated proportional control valve.
The rotor 6 of the motor integrated with the rotor 6 is housed in a case 7 made of a non-magnetic material, and outside the case 7 is a stator coil 3 for applying a rotating magnetic field to the rotor 6.
This invention relates to a proportional control valve that uses a fixing band that is inexpensive and has good workability, which also serves to stop the rotation of the stator coil 3 and protect the lead wire 8. be.
従来の比例制御弁では、第１図に示すように、
非磁性体からなる円筒状のケース７外周に固定子
コイル３をはめ込んでケース７の開放端側の段付
拡大部９に当接させるとともに、固定子コイル３

上に巻き付け、締付部２をねじ１０で締付けるこ
とにより固定子コイル３の軸方向の移動を防止し
ていた。 In the conventional proportional control valve, as shown in Fig. 1,
The stator coil 3 is fitted into the outer periphery of the cylindrical case 7 made of a non-magnetic material and brought into contact with the stepped enlarged part 9 on the open end side of the case 7.
Immediately after, attach the ring-shaped fixing band 1 to the case 7.
The stator coil 3 is prevented from moving in the axial direction by wrapping it around the top and tightening the tightening portion 2 with a screw 10.
このような構造の固定バンドでは、固定子コイ
ル３の周方向の移動防止は不可能であり、振動あ
るいは固定子コイル３へ通電時の回転子６との反
力により固定子コイル３が回転移動したりして、
弁の流量制御機能を損なうという欠点があつた。 With a fixed band having such a structure, it is impossible to prevent the stator coil 3 from moving in the circumferential direction, and the stator coil 3 may rotate due to vibration or a reaction force with the rotor 6 when the stator coil 3 is energized. Or,
This had the disadvantage of impairing the flow control function of the valve.
また、固定子コイル３の絶縁とリード線８の損
傷防止を目的として、固定子コイル３を弾力のあ
る樹脂にて固め（たとえば、エポキシ注型などに
より）、それと同時にリード線を一ケ所にまとめ、
この取出口４を前記樹脂にて固めるということが
行われているが、ある程度以上の力がリード線の
根元にかかると、リード線８を保護していた取出
口４の樹脂がはく離するという問題があつた。 In addition, for the purpose of insulating the stator coil 3 and preventing damage to the lead wire 8, the stator coil 3 is hardened with elastic resin (for example, by epoxy casting), and at the same time, the lead wires are gathered in one place. ,
This outlet 4 is hardened with the resin, but if a certain amount of force is applied to the base of the lead wire, the resin of the outlet 4 that protects the lead wire 8 will peel off. It was hot.
本考案は、これらの問題を解決するために、第
３図、第４図に示すように従来のリング状のバン
ドの締付部２を固定子コイル３のリード線取出口
４の樹脂まで延長して、締付部２の先端で取出口
４部をはさみ込むようにしたものである。 In order to solve these problems, the present invention extends the tightening part 2 of the conventional ring-shaped band to the resin of the lead wire outlet 4 of the stator coil 3, as shown in FIGS. 3 and 4. The distal end of the tightening part 2 is arranged to sandwich the outlet 4 part.
このように構成した固定バンドで、締付部の中

取出口４の樹脂を締付部２で保護、補強する形と
なるため、樹脂がはがれず、リード線を保護する
といつた利点がある。 With the fixing band configured in this way, screw 10 at the center of the tightening part (lower part of lead wire outlet 4).
By tightening the clamping part 2 by means such as the above, the ring part on the case 7 is crimped onto the case 7, preventing the stator coil 3 from moving in the axial direction, and at the same time, the upper end of the clamping part 2 Since the lead wire outlet 4 is sandwiched and crimped, movement of the stator coil 3 in the circumferential direction can be prevented. Furthermore, since the resin at the lead wire outlet 4 is protected and reinforced by the tightening portion 2, there is an advantage that the resin does not come off and the lead wires are protected.
以上のように本考案はリング状のバンドの締付

固定バンドであるから、その実用的効果は大なる
ものである。 As described above, the present invention extends the tightening part 2 of the ring-shaped band to the resin of the lead wire outlet 4 of the stator coil 3, and tightens it by sandwiching the outlet 4 with the tip of the tightening part 2. By tightening the center part of the part with the screw 10, it is an inexpensive and easy-to-work fixing band that prevents the rotation of the stator coil 3 and protects the lead wire 8, so its practical effects are great. be.
