　本発明は、流体流量を調節するバルブを駆動するバルブ駆動装置に関するものである。 The present invention relates to a valve drive device that drives a valve that adjusts a fluid flow rate.

　特許文献１に記載の弁体駆動装置は、バルブを駆動するモータに電力を供給するコネクタを備えている。弁体駆動装置は、外部装置に取り付けられる下カバー部材と、バルブ本体と、バルブ本体を覆う上カバー部材とを備えている。下カバー部材に上カバー部材を取りつけることで、バルブ本体を挟み込み、固定する。この弁体駆動装置においてコネクタは、上カバー部材に取りつけられている。上カバー部材にキャップ部材を装着することで、コネクタは、上カバー部材とキャップとの間に挟みこまれ、上カバー部材及びキャップ部材に対して固定される。 The valve body drive device described in Patent Document 1 includes a connector that supplies electric power to a motor that drives the valve. The valve body drive device includes a lower cover member that is attached to an external device, a valve body, and an upper cover member that covers the valve body. By attaching the upper cover member to the lower cover member, the valve body is sandwiched and fixed. In this valve body drive device, the connector is attached to the upper cover member. By mounting the cap member on the upper cover member, the connector is sandwiched between the upper cover member and the cap and fixed to the upper cover member and the cap member.
　しかしながら、この構成では、下カバー部材に上カバー部材を取りつけて、バルブ本体を固定する作業を行った上で、キャップ部材を上カバー部材に取りつけてコネクタを固定する作業を行うので、作業工程が増えるとともに部品点数が増加するという問題がある。 However, in this configuration, since the upper cover member is attached to the lower cover member and the valve body is fixed, the cap member is attached to the upper cover member and the connector is fixed. There is a problem that the number of parts increases as the number of parts increases.
　特許文献２に記載のモータのステータ構造では、ケース内に、ステータと、回路基板と、コネクタとを固定する構成を取っている。この構成では、ケース内に、ステータ、回路基板及びコネクタを配置した後、樹脂材料をケース内に充填し、これらの構成を固定する。 In the motor stator structure described in Patent Document 2, the stator, the circuit board, and the connector are fixed in the case. In this configuration, after the stator, the circuit board, and the connector are arranged in the case, a resin material is filled in the case to fix these configurations.
　しかしながら、この構成では、例えば、モータの使用環境が樹脂材料による封止が必要のない場合であっても、コネクタをケースに固定するために封止樹脂が必要であるため、樹脂を封止するための面倒な樹脂充填作業が必要となる。さらに、これらの作業及び封止樹脂により、モータのコストが増加するという問題がある。 However, in this configuration, for example, even when the use environment of the motor does not need to be sealed with the resin material, the sealing resin is required to fix the connector to the case, and thus the resin is sealed. Therefore, a troublesome resin filling work is required. Furthermore, there is a problem that the cost of the motor increases due to these operations and the sealing resin.
　本発明は、上記問題点に鑑みてなされたもので、簡素な構成でコネクタを固定でき、組立作業の作業性を向上させるバルブ駆動装置を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a valve drive device capable of fixing a connector with a simple configuration and improving workability of assembly work.

And a first housing member in which any one of the stator is arranged, and a second housing member in which the other of the valve body and the stator is arranged, and the second housing member is provided in the first housing member.

It is possible to improve the workability of the assembly work. Furthermore, since the connector can be fixed only by sandwiching it between the first housing member and the second housing member, the fixing structure of the connector can be simplified.

As an example, the first direction positioning portion 26f is arranged in the connector positioning portion 26b on the + Y direction side, that is, on the side of the stator housing portion 26a, and is formed at two locations at intervals in the X axis direction. As shown in FIG. 7, the first direction positioning portion 26f is composed of a pair of a first direction position defining surface 26j and a first direction pressing portion 26g. The first direction pressing portions 26g are provided on the −Y direction side in the connector positioning portion 26b, and are formed at two locations so as to face the first direction position defining surface 26j at intervals in the X axis direction.

In the present embodiment, when the connector 28 is attached to the connector positioning portion 26b, a part of the connector 28, specifically, the foot portion 28a and the first direction pressing portion 26g are configured to interfere in the Y-axis direction. A part of the first direction pressing portion 26g elastically deforms in the −Y axis direction to generate an elastic force, and presses the connector 28 toward the + Y axis direction. As a result, the connector 28 is pressed against the first-direction position defining surface 26j, and the position of the connector 28 in the Y-axis direction (first direction) is defined.
　図８に示すように、第２方向位置決め部２６ｈはコネクタ位置決め部２６ｂ内において互いに対向するように配置されている。一例として、一対の第２方向位置決め部２６ｈは、＋Ｘ軸方向又は－Ｘ軸方向に向かってそれぞれ突出し、コネクタ位置決め部２６ｂのＸ軸方向の幅を狭めるように形成されている。 As shown in FIG. 8, the second-direction positioning portions 26h are arranged in the connector positioning portion 26b so as to face each other. As an example, the pair of second direction positioning portions 26h are formed so as to respectively project in the + X axis direction or the −X axis direction and narrow the width of the connector positioning portion 26b in the X axis direction.
　本実施形態において、コネクタ位置決め部２６ｂにコネクタ２８を取り付けると、コネクタ２８のＸ軸方向の両側面にそれぞれ一対の第２方向位置決め部２６ｈが接触する。これにより、コネクタ２８はＸ軸方向における変位を一対の第２方向位置決め部２６ｈにより規制される。したがって、一対の第２方向位置決め部２６ｈは、Ｘ軸方向（第２方向）におけるコネクタ２８の位置を規定する。 In the present embodiment, when the connector 28 is attached to the connector positioning portion 26b, the pair of second direction positioning portions 26h come into contact with both side surfaces of the connector 28 in the X-axis direction. As a result, the connector 28 is restricted from being displaced in the X-axis direction by the pair of second-direction positioning portions 26h. Therefore, the pair of second-direction positioning portions 26h define the position of the connector 28 in the X-axis direction (second direction).

　ここで、符号３は傾斜面であり、該傾斜面３は，第２方向位置規定面２６ｒ及び第２方向押圧部２６ｑのそれぞれの先端に形成されており、コネクタ２８のＺ方向への挿入を受け入れてガイドするためのものである。 When the connector 28 is inserted and attached to the connector positioning portion 26b in the Z direction, one second direction pressing portion 26q is elastically deformed based on its shape, and the repulsive force causes the connector 28 to serve as two positioning surfaces 26p. The second direction position defining surface 26r is pressed. As a result, the connector 28 is positioned with the second direction position defining surface 26r as the reference position.
Here, reference numeral 3 is an inclined surface, and the inclined surface 3 is formed at the tip of each of the second direction position defining surface 26r and the second direction pressing portion 26q, and the connector 28 can be inserted in the Z direction. It is for acceptance and guidance.
