Description

電磁弁solenoid valve
　本発明は、電磁弁本体と、電磁弁本体の電線引込口に取り付けられる端子箱と、を備えた電磁弁に関するものである。 The present invention relates to a solenoid valve provided with a solenoid valve body and a terminal box attached to a wire inlet of the solenoid valve body.
　流体の流路を開閉する電磁弁として、電磁弁本体と、端子箱と、を備えたものが公知である。電磁弁本体は、弁孔を開閉するプランジャ、該プランジャを電磁駆動するソレノイド、これらを収容したボデー等を備えている。端子箱は、電磁弁本体のボデーの電線引込口に取り付けられる管状の部材であり、ソレノイドに通電を行う外部電線や、電磁弁本体を制御するための信号伝送を行う外部電線を、その内側に通して案内するものである（例えば特許文献１を参照。）。 As an electromagnetic valve for opening and closing a fluid flow path, an electromagnetic valve having a main body of a solenoid valve and a terminal box is known. The electromagnetic valve body includes a plunger that opens and closes a valve hole, a solenoid that electromagnetically drives the plunger, a body that accommodates these, and the like. The terminal box is a tubular member that is attached to the wire inlet of the body of the solenoid valve body, and an external wire that energizes the solenoid and an external wire that performs signal transmission for controlling the solenoid valve body are inside the terminal box. It guides through (for example, refer patent document 1).
　上記電磁弁の一例として、端子箱が、電線引込口に対し回転可能に取り付けられたものがある。当該電磁弁においては、外部電線が接続される端子台が端子箱内に固定されており、この端子台が内部電線によってソレノイド側と接続されている。このような電磁弁においては、ユーザーが端子箱の角度を変更することができるので、外部電線の配線時等に当該外部電線の取り回しを容易にすることができる。 As an example of the electromagnetic valve, there is one in which a terminal box is rotatably attached to a wire inlet. In the solenoid valve, a terminal block to which an external electric wire is connected is fixed in a terminal box, and this terminal block is connected to the solenoid side by an internal electric wire. In such a solenoid valve, since the user can change the angle of the terminal box, it is possible to easily handle the external electric wire when wiring the external electric wire.

　しかしながら、上述した端子箱が回転可能な電磁弁においては、端子台とソレノイド側とを接続した内部電線の過度のねじれによる断線を避けるため、端子箱の回転角度に制限があり、端子箱の回転範囲をさらに拡げるという点において改善の余地があった。 However, in the solenoid valve that can rotate the terminal box described above, the rotation angle of the terminal box is limited in order to avoid disconnection due to excessive twisting of the internal wire connecting the terminal block and the solenoid side. There was room for improvement in terms of further expanding the range.
　そこで、本発明は、電磁弁本体の電線引込口に対し、端子箱の回転自由度を向上させた電磁弁を提供することを目的とする。 Therefore, an object of the present invention is to provide an electromagnetic valve in which the degree of freedom of rotation of the terminal box is improved with respect to the wire inlet of the electromagnetic valve body.
　上記課題を解決するため、本発明の電磁弁は、電磁弁本体と、該電磁弁本体を構成するボデーの電線引込口に取り付けられる端子箱と、を備え、前記端子箱は、一端側が前記電線引込口内に挿入され、他端側が前記電線引込口外に位置付けられる円筒部と、該円筒部の他端側の外周面から延設され、前記電線引込口外に位置付けられる電線案内部と、を備え、前記電磁弁本体は、前記電線案内部内を通されて前記円筒部内に引き込まれた電線と電気的に接続される端子台と、該端子台を支持する支持部材と、を備え、前記端子箱は、前記電線引込口に対し、前記円筒部の周方向に沿って３６０度回転可能に取り付けられていることを特徴とする。 In order to solve the above problems, an electromagnetic valve of the present invention includes an electromagnetic valve main body and a terminal box attached to an electric wire inlet of a body constituting the electromagnetic valve main body, and the terminal box has one end side of the electric wire. A cylindrical portion that is inserted into the inlet, and the other end side is positioned outside the wire inlet, and an electric wire guide that extends from the outer peripheral surface of the other end of the cylindrical portion and is positioned outside the wire inlet, The electromagnetic valve body includes a terminal block that is electrically connected to an electric wire that is passed through the wire guide portion and drawn into the cylindrical portion, and a support member that supports the terminal block, and the terminal box includes: It is characterized by being attached to the wire inlet so as to be capable of rotating 360 degrees along the circumferential direction of the cylindrical portion.
　本発明によれば、電磁弁本体が端子台と該端子台を支持する支持部材とを備えているので、端子箱を回転させても端子台及び該端子台とソレノイド側とを接続した部品（電線等）は回転しない。このように、本発明の電磁弁は、端子箱の回転による前記部品の断線を防止できるので、電磁弁本体の電線引込口に対し、端子箱を３６０度回転させることが可能となり、回転自由度を向上させることができる。 According to the present invention, since the solenoid valve body includes the terminal block and the support member that supports the terminal block, the terminal block and the component that connects the terminal block and the solenoid side even when the terminal box is rotated ( Wires etc.) do not rotate. Thus, since the solenoid valve of the present invention can prevent disconnection of the parts due to the rotation of the terminal box, the terminal box can be rotated 360 degrees with respect to the electric wire inlet of the solenoid valve body, and the degree of freedom of rotation is increased. Can be improved.

In the present example, the second substrate 20 is disposed facing the wire inlet 55, that is, one opening of the body 5.
　図３に示す電線引込口５５に端子箱３が取り付けられた状態において、端子台２２は、電線案内部３１，３２の直下に位置付けられている。より正確には、端子台２２は、円筒部３０内における電線案内部３１，３２の中心軸Ｐの延長線上の位置よりも、少々一端３０ａ側に位置付けられている。また、支持部材１９は、その殆どの部分が円筒部３０内に位置付けられている。すなわち、支持部材１９は、端子台２２を、円筒部３０内における電線案内部３１，３２の中心軸Ｐの延長線上の位置に近付けるように、円筒部３０の一端３０ａ側から他端３０ｂ側に向かって延びている。 In the state where the terminal box 3 is attached to the wire inlet 55 shown in FIG. 3, the terminal block 22 is positioned directly below the wire guide portions 31 and 32. More precisely, the terminal block 22 is positioned slightly closer to the one end 30 a than the position on the extension line of the central axis P of the wire guide portions 31 and 32 in the cylindrical portion 30. Further, most of the support member 19 is positioned in the cylindrical portion 30. That is, the support member 19 moves the terminal block 22 from the one end 30a side to the other end 30b side of the cylindrical portion 30 so as to approach the position on the extension line of the central axis P of the wire guide portions 31 and 32 in the cylindrical portion 30. It extends towards.
　上記構成の電磁弁１は、端子台２２を搭載した第２の基板２０が支持部材１９によって電磁弁本体２のボデー５側に固定されているので、端子箱３を回転させても端子台２２や電線１６は回転しない。これにより、端子箱３の回転による電線１６の断線を防止できるので、電線引込口５５に対し、端子箱３を３６０度回転させることが可能となっている。このような電磁弁１は、電線６の配線時等に当該電線６の取り回しを容易にすることができる。 In the electromagnetic valve 1 having the above configuration, since the second substrate 20 on which the terminal block 22 is mounted is fixed to the body 5 side of the electromagnetic valve main body 2 by the support member 19, the terminal block 22 is rotated even if the terminal box 3 is rotated. And the electric wire 16 does not rotate. Thereby, since the disconnection of the electric wire 16 due to the rotation of the terminal box 3 can be prevented, the terminal box 3 can be rotated 360 degrees with respect to the electric wire inlet 55. Such a solenoid valve 1 can facilitate handling of the electric wire 6 when the electric wire 6 is wired.
　また、電磁弁１は、支持部材１９をボデー５側に固定するために、第１の基板１３と第２の基板２０との間に配置された板１４を用いているので、ボデー５の径方向の肥大化を抑制できている。すなわち、板１４を用いることで、ボデー５を径方向に肥大化させることなく支持部材１９の取付けスペースを確保している。さらに、この板１４を第１の基板１３の近傍に配置したことで、この板１４によって第１の基板１３を保護できるようになっている。 Moreover, since the solenoid valve 1 uses the plate 14 disposed between the first substrate 13 and the second substrate 20 in order to fix the support member 19 to the body 5 side, the diameter of the body 5 The direction of enlargement can be suppressed. That is, by using the plate 14, a space for mounting the support member 19 is ensured without enlarging the body 5 in the radial direction. Furthermore, since the plate 14 is disposed in the vicinity of the first substrate 13, the first substrate 13 can be protected by the plate 14.
　また、電磁弁１は、図３に示すように、電線案内部３１，３２から端子台２２までの電線配索経路をほぼ直線状とすることができ、電線６にかかる負荷を少なくできる。 Further, as shown in FIG. 3, the electromagnetic valve 1 can make the wire routing path from the wire guide portions 31 and 32 to the terminal block 22 substantially linear, and reduce the load applied to the wire 6.
　さらに、ボデー５の外表面５０には、落下物等による耐衝撃性を向上させるための凹凸が設けられている。本例では、図１～３に示すように、ボデー５に、その外表面５０から凹の凹部５１が複数設けられている。 Furthermore, the outer surface 50 of the body 5 is provided with unevenness for improving the impact resistance due to falling objects. In this example, as shown in FIGS. 1 to 3, the body 5 is provided with a plurality of concave portions 51 that are recessed from the outer surface 50 thereof.
　各凹部５１は、図４に示すように、略半円状の第１の平面５２ａ及び第２の平面５２ｂによって構成されている。本例において、これら第１の平面５２ａ及び第２の平面５２ｂは、同一形状かつ同一サイズである。第１の平面５２ａは、弧部５４ａと、弧部５４ａの両端部を結んだ弦部５３ａと、を有している。同様に、第２の平面５２ｂは、弧部５４ｂと、弧部５４ｂの両端部を結んだ弦部５３ｂと、を有している。　第１の平面５２ａの弦部５３ａと第２の平面５２ｂの弦部５３ｂとは重なっており、第１の平面５２ａと第２の平面５３ａとは角度を成している。また、このような複数の凹部５１は、千鳥状に配置されている。 As shown in FIG. 4, each recess 51 is constituted by a substantially semicircular first plane 52 a and a second plane 52 b. In the present example, the first plane 52a and the second plane 52b have the same shape and the same size. The first plane 52a has an arc portion 54a and a string portion 53a that connects both ends of the arc portion 54a. Similarly, the second plane 52b has an arc part 54b and a string part 53b connecting both ends of the arc part 54b. The chord part 53a of the first plane 52a and the chord part 53b of the second plane 52b overlap each other, and the first plane 52a and the second plane 53a form an angle. Moreover, such a plurality of recesses 51 are arranged in a staggered manner.
　本例において、弦部５３ａ，５３ｂの長さは、約２５ｍｍであり、弧部５４ａの中央部から弧部５４ｂの中央部までの長さは、約２０ｍｍである。本発明ではこの数値に限定されず、弦部５３ａ，５３ｂの長さを２０～３０ｍｍの範囲内で適宜変更可能であり、弧部５４ａの中央部から弧部５４ｂの中央部までの長さを１５～２５ｍｍの範囲内で適宜変更可能である。 In this example, the length of the string portions 53a and 53b is about 25 mm, and the length from the central portion of the arc portion 54a to the central portion of the arc portion 54b is about 20 mm. In the present invention, the length of the chord portions 53a and 53b can be appropriately changed within a range of 20 to 30 mm, and the length from the central portion of the arc portion 54a to the central portion of the arc portion 54b can be changed. It can be appropriately changed within the range of 15 to 25 mm.
　凹部５１を上述した形状とすることで、落下物等による耐衝撃性をより向上させることができる。なお、上述した実施形態では、第１の平面５２ａ及び第２の平面５２ｂが略半円状であったが、これら第１の平面５２ａ及び第２の平面５２ｂは、略半楕円状であっても、優れた耐衝撃性を発揮することができる。 By making the recess 51 have the shape described above, it is possible to further improve the impact resistance due to falling objects. In the above-described embodiment, the first plane 52a and the second plane 52b are substantially semicircular. However, the first plane 52a and the second plane 52b are substantially semi-elliptical. Can also exhibit excellent impact resistance.
