図９は、第１従来例として示した制御装置で、前面の意匠面１１にスイッチ操作部１２を有する制御装置となっており、装置ケース１３の内部には、タクトスイッチ１４やＬＥＤ１５などの電気部品を設けたプリント基板１６がねじ止めなどによって配設されている。   FIG. 9 is a control device shown as a first conventional example, which is a control device having a switch operation unit 12 on a front design surface 11. Electricity such as a tact switch 14 and an LED 15 is provided inside the device case 13. A printed circuit board 16 provided with components is disposed by screwing or the like.

そして、この制御装置の内部には、装置ケース１３の裏側から供給されたポッティング剤（封止樹脂）１７を充填させて浸水を防ぐ防水構造となっているが、ポッティング剤の付着によってタクトスイッチ１４が動作不良となったり、ＬＥＤ１５の発光が遮られる等の支障があるため、これら電気部品にポッティング剤の付着を防ぐためのラバー１８が設けられている。   The interior of the control device is filled with a potting agent (sealing resin) 17 supplied from the back side of the device case 13 to prevent water from entering. The tact switch 14 is attached by the adhesion of the potting agent. Therefore, the rubber 18 is provided to prevent the potting agent from adhering to these electrical components.

図１０は、第２従来例として示した制御装置で、装置ケース２１内には、電気部品２２を設けたプリント基板２３が配設され、また、装置ケース２１内がポッティング剤（封止樹脂）２４によって充填されている。

実開昭６１−１２１７８０号Japanese Utility Model Sho 61-121780

上記した第１、第２従来例の制御装置は、装置ケース内の多くの部分にポッティング剤を充填させて防水する構造となっているため、ポッティング剤を大量に使用したものとなっている。
したがって、プリント基板に設けるスイッチやＬＥＤなどの電気部品が多くなったり、各電気部品の間隔が狭くなると、ラバーだけではポッティング剤の付着を防ぐことが困難となる。 The control devices according to the first and second conventional examples have a structure in which many portions in the device case are filled with a potting agent to be waterproof, and therefore a large amount of the potting agent is used.
Therefore, when the number of electrical components such as switches and LEDs provided on the printed circuit board is increased or the interval between the electrical components is reduced, it is difficult to prevent the potting agent from adhering with rubber alone.

さらに、大量のポッティング剤を使用するために、制御装置の重量が増すばかりでなく、ポッティング剤のコストもアップすることになる。
そこで、本発明では、封止樹脂としてのポッティング剤の使用量を可能なる限り少なくして防水性能を高めた制御装置の防水構造を提供することを目的とする。 Furthermore, the use of a large amount of potting agent not only increases the weight of the control device, but also increases the cost of the potting agent.
Therefore, an object of the present invention is to provide a waterproof structure for a control device that has improved waterproof performance by reducing the amount of potting agent used as a sealing resin as much as possible.

上記した目的を達成するため、本発明では、第１の発明として、制御部材である電気部品を設けたプリント基板が内装された装置ケースの防水構造において、 前記装置ケースは、第１ケースと、この第１ケースの開口部を塞ぐ第２ケースとで形成し、さらに、前記第１ケースと第２ケースとの連結部には防水手段を備えると共に、前記第２ケースには、前記プリント基板を外部装置と電気接続する接続部材を引き出すコネクタ部を設け、前記防水手段は、前記第１ケースの開口側となる周側面に圧接させる第２ケースに設けた第１シール部と、前記プリント基板に対する前記コネクタ部の対向面に設けた第２シール部とから形成したことを特徴とする制御装置の防水構造を提案する。   In order to achieve the above-described object, in the present invention, as a first invention, in a waterproof structure of a device case in which a printed circuit board provided with an electrical component as a control member is provided, the device case includes the first case, The second case closes the opening of the first case, and the connecting portion between the first case and the second case is provided with waterproof means, and the second case includes the printed circuit board. A connector portion for pulling out a connection member that is electrically connected to an external device is provided, and the waterproof means is provided with a first seal portion provided in a second case that is pressed against a peripheral side surface that is an opening side of the first case, and the printed circuit board. A waterproof structure for a control device is proposed, which is formed from a second seal portion provided on an opposing surface of the connector portion.

第２の発明としては、上記した第１の発明の防水構造において、前記第２ケースには、その周囲に沿って前記第１ケースの開口側となる周側面を嵌入させる溝状部を形成し、この溝状部の溝面に沿って前記第１シール部を設けたことを特徴とする制御装置の防水構造を提案する。   As a second invention, in the waterproof structure of the first invention described above, a groove-like portion is formed in the second case for fitting a peripheral side surface that becomes the opening side of the first case along the periphery thereof. Then, a waterproof structure for a control device is proposed in which the first seal portion is provided along the groove surface of the groove-like portion.

第３の発明としては、上記した第２の発明の防水構造において、前記防水手段の第１、第２シール部を第２ケースと一体形成するために、シール材を供給するゲート孔を前記溝状部に設けたことを特徴とする制御装置の防水構造を提案する。   As a third invention, in the waterproof structure of the above-described second invention, a gate hole for supplying a sealing material is formed in the groove so as to integrally form the first and second seal portions of the waterproof means with the second case. Proposed is a waterproof structure for a control device, characterized in that it is provided in the shape part.

第４の発明としては、上記した第１〜第３の発明のいずれかの防水構造において、前記第２シール部には、前記プリント基板と前記接続部材との電気接続部を囲って前記プリント基板に圧接させるリブを形成し、さらに、前記電気接続部を覆う封止樹脂を前記コネクタ部の内部に充填させたことを特徴とする制御装置の防水構造を提案する。   As a fourth invention, in the waterproof structure according to any one of the first to third inventions described above, the printed circuit board surrounds an electrical connection portion between the printed circuit board and the connection member in the second seal portion. A waterproof structure for a control device is proposed, in which ribs are formed in pressure contact with each other, and a sealing resin that covers the electrical connection portion is filled in the connector portion.

第１の発明は、プリント基板を内装させた装置ケースが第１ケースと第２ケースとで形成され、第１、第２ケースの接合部には第１シール部からなる防水手段が設けられている。
そして、第１シール部が、第１ケースの開口側となる周側面に圧接させる第２ケースに設けたシール部構成となっているので、装置ケースの周囲からの浸水が防止される。 In the first invention, a device case having a printed circuit board is formed by a first case and a second case, and a waterproof means including a first seal portion is provided at a joint portion of the first and second cases. Yes.
And since the 1st seal | sticker part becomes a seal | sticker part structure provided in the 2nd case press-contacted to the surrounding side surface used as the opening side of a 1st case, the inundation from the circumference | surroundings of an apparatus case is prevented.

また、プリント基板を外部装置と電気接続する接続部材を引き出すコネクタ部については、プリント基板に対するコネクタ部の対向面に第２シール部を設けた防水構造としてある。
したがって、本発明の制御装置は、第１、第２ケースと、第１、第２シール部である防水手段とによって、装置ケース内が閉塞されるので、外部からの浸水が確実に防止される。 In addition, the connector part that pulls out the connection member that electrically connects the printed circuit board to the external device has a waterproof structure in which a second seal part is provided on the surface of the connector part facing the printed circuit board.
Therefore, in the control device of the present invention, the inside of the device case is closed by the first and second cases and the waterproof means that are the first and second seal portions, so that inundation from the outside is reliably prevented. .

このことから、特に、ポッティング剤（封止樹脂）を使用しないで防水が可能になるから、従来例のように、ラバーだけではポッティング剤の付着が困難になったり、また、大量のポッティング剤の使用により制御装置の重量が増したり、ポッティング剤のコストもアップするなどの問題がない。 This makes waterproofing possible without using a potting agent (sealing resin), so that it is difficult to attach the potting agent with rubber alone as in the conventional example, and a large amount of potting agent There is no problem that the weight of the control device increases due to use or the cost of the potting agent increases.

第２の発明は、第２ケースの周囲に沿って第１ケースの開口側となる周側面を嵌入させる溝状部を形成し、この溝状部の溝面に沿って前記したところの第１シール部を設けた構成の防水構造が特徴となっている。   According to a second aspect of the present invention, a groove-like portion is formed along the periphery of the second case to fit a peripheral side surface that is the opening side of the first case, and the first portion described above along the groove surface of the groove-like portion. It is characterized by a waterproof structure with a seal portion.

第３の発明は、第１、第２シール部を第２ケースと一体形成するために、シール材を供給するゲート孔を前記溝状部に設けたことが特徴となっている。
このように構成すれば、第１、第２のシール部を組付ける作業がいらないし、第１、第２のシール部を一回の形成工程で製造できるので、製造工程を簡素化することができる。 The third invention is characterized in that a gate hole for supplying a sealing material is provided in the groove-shaped portion in order to integrally form the first and second seal portions with the second case.
If comprised in this way, the operation | work which assembles a 1st, 2nd seal part is unnecessary, and since a 1st, 2nd seal part can be manufactured in one formation process, a manufacturing process can be simplified. it can.

第４の発明は、第２シール部にリブを設けてプリント基板に圧接させる構成としたので、シール性能を高めることができる他、プリント基板を確実に固定させることができる。
また、コネクタ部内部には封止樹脂を充填するが、上記のリブにより制御装置内への封止樹脂の漏れを防ぐことができる。
さらに、封止樹脂はコネクタ部の内部に充填するだけで足りるので、従来例の制御装置の封止樹脂の使用量に比べ大幅に減少させることができる。 According to the fourth aspect of the invention, since the rib is provided on the second seal portion and pressed against the printed circuit board, the sealing performance can be improved and the printed circuit board can be fixed securely.
Moreover, although sealing resin is filled inside the connector portion, leakage of the sealing resin into the control device can be prevented by the rib.
Furthermore, since the sealing resin only needs to be filled in the connector portion, the amount of the sealing resin used in the control device of the conventional example can be greatly reduced.
