回路基板に電気的に接続された端子台を持つ送風装置では、外部配線との接続は端子台において施工業者により行われる。この接続作業において回路基板及び回路基板と端子台との配線は操作又は破損されては困るものである。回路基板には配線作業に伴う鉄線屑等が混入してもトラブルの原因になり、鉄線屑等の混入は回避しなければならない。こうしたことを回避するには従来のカバーでははなはだ不完全である。即ち、回路基板や端子台を一括して覆うカバーは、カバーを外せば回路基板も露出してしまい、破損や配線作業に伴う鉄線屑等の混入は阻めない。カバーにカバーを設け、端子台を呈出させても回路基板はもう一つのカバーで被覆されているものでも、回路基板を収めている空間と端子台を収めている空間は連なっていて、やはり回路基板の破損や配線作業に伴う鉄線屑等の混入の回避は不完全である。   In an air blower having a terminal block electrically connected to a circuit board, connection with external wiring is performed by a contractor at the terminal block. In this connection operation, the circuit board and the wiring between the circuit board and the terminal block are troublesome if operated or damaged. Even if iron wire scraps or the like due to wiring work are mixed in the circuit board, it may cause trouble, and mixing of iron wire scraps or the like must be avoided. To avoid this, conventional covers are incomplete. That is, if the cover that covers the circuit board and the terminal block is removed, the circuit board is also exposed if the cover is removed. Even if the cover is provided on the cover and the terminal block is presented, even if the circuit board is covered with another cover, the space containing the circuit board and the space containing the terminal block are connected. Avoiding the breakage of circuit boards and the mixing of iron wire scraps associated with wiring work is incomplete.

本発明は、上記した従来の問題点を解決するためになされたもので、端子台を使って外部配線との接続作業をする場合でも、回路基板は全体が被覆されたままで呈出しない保護機能の優れた、回路基板に電気的に接続された端子台を備えた送風装置を得ることであり、回路基板の保護に関する構成の簡素化や操作性の向上を図ることである。   The present invention has been made in order to solve the above-described conventional problems, and even when a connection work with external wiring is performed using a terminal block, the circuit board is not covered and is not exposed as a whole. It is to obtain a blower provided with a terminal block electrically connected to a circuit board, and to simplify the configuration relating to protection of the circuit board and improve operability.

上記目的を達成するために本発明は、送風装置の電気部品に電気的に接続された回路基板とこの回路基板に電気的に接続された端子台の少なくとも回路基板を送風装置の外郭に取付け、回路基板と端子台を端子台の外部配線との接続部を除いて外郭に固定手段で固定される第１のカバーで前記回路基板を露出することなく全体を覆い、第１のカバーの端子台の外部配線の接続部の臨む部分を別に覆う第２のカバーを着脱可能に取付ける手段を採用する。 In order to achieve the above object, the present invention attaches at least a circuit board of a circuit board electrically connected to an electrical component of the blower and a terminal block electrically connected to the circuit board to the outer shell of the blower, The circuit board and the terminal block are covered with a first cover that is fixed to the outer shell by fixing means except for a connection part between the terminal board and external wiring, and the terminal board of the first cover is covered without exposing the circuit board. A means for detachably attaching a second cover that separately covers a portion facing the connection portion of the external wiring is employed.

本発明によれば、外部配線との接続は第２のカバーを外して端子台の接続部を呈出させて行うことができる。このとき、回路基板全体及び回路基板と端子台との接続も全体が第１のカバーで覆われたままで露出することがなく、破損や配線作業に伴う鉄線屑等の混入は事実上略完全に回避される。   According to the present invention, the connection with the external wiring can be performed by removing the second cover and presenting the connection portion of the terminal block. At this time, the entire circuit board and the connection between the circuit board and the terminal block are not exposed while the entire cover is covered with the first cover, and the inclusion of iron wire scraps and the like due to breakage and wiring work is virtually completely completed. Avoided.

本発明の送風装置は、据付け時や取外してメンテナンスを行い再度据付ける際に、操作されたり、異物が混入したり、破損されては困る装置外郭に取付けられた回路基板を確り保護する対策を講じたものである。この送風装置は、送風機等の電気部品に電気的に接続された回路基板と回路基板に電気的に接続された端子台が装置の外郭の一面に近接して取付けられている。回路基板と端子台は、端子台の外部配線との接続部を除いて外郭にネジ等の固定手段で固定される第１のカバーで全体が覆われている。この第１のカバーの端子台の外部配線の接続部の臨む部分は、別の第２のカバーで覆われている。第２のカバーは、ネジ等の固定手段で独自に着脱可能に外郭や第１のカバーに取付けられている。第１のカバーの固定手段は第２のカバーで覆われ、第２のカバーを外さない限りその固定手段を操作することはできないようになっている。端子台に接続された外部配線は第２のカバーに設けられた、難燃性ブッシュの装着された引出口から外部に引出されている。本発明の送風装置によれば、外部配線との接続操作及び接続解除操作は第２のカバーを外して端子台の接続部を呈出させて行うことができる。このとき、回路基板全体及び回路基板と端子台との接続構成も全体が第１のカバーで覆われたままで露出することがなく、操作されたり破損を招いたり、配線作業に伴う鉄線屑等の混入も事実上略完全に回避される。   The blower of the present invention is a measure to ensure and protect the circuit board attached to the outer shell of the device that is troubled when it is installed or removed and maintenance is performed and then re-installed. It was taken. In this blower device, a circuit board electrically connected to an electrical component such as a blower and a terminal block electrically connected to the circuit board are attached in close proximity to one surface of the outer shell of the device. The circuit board and the terminal block are entirely covered with a first cover that is fixed to the outer periphery by a fixing means such as a screw except for a connection portion with the external wiring of the terminal block. The portion of the terminal block of the first cover that faces the connection portion of the external wiring is covered with another second cover. The second cover is attached to the outer shell and the first cover so as to be detachable independently by fixing means such as screws. The fixing means of the first cover is covered with the second cover, and the fixing means cannot be operated unless the second cover is removed. The external wiring connected to the terminal block is led out to the outside from an outlet provided in the second cover and equipped with a flame retardant bush. According to the blower of the present invention, the connection operation and the connection release operation with the external wiring can be performed by removing the second cover and presenting the connection portion of the terminal block.

実施の形態１．
図１は、本実施の形態の送風装置の正面図、図２は、他の形態の送風装置の正面図、図３は、回路基板と端子台のカバーを示す断面図、図４は、端子台のカバーを示す斜視図、図５は、回路基板と端子台の他の形態のカバーを示す断面図である。 Embodiment 1 FIG.
1 is a front view of a blower device according to the present embodiment, FIG. 2 is a front view of a blower device according to another embodiment, FIG. 3 is a cross-sectional view showing a cover of a circuit board and a terminal block, and FIG. FIG. 5 is a cross-sectional view showing a cover of another form of the circuit board and the terminal block.

本実施の形態は、据付け時や取外してメンテナンスを行い再度据付ける際に、操作されたり、異物が混入したり、破損されては困る装置外郭に取付けられた回路基板を確り保護する対策を講じた図１や図２に全体を示すような送風装置に関するものである。この送風装置は、送風機等の電気部品１に電気的に接続された回路基板２と回路基板２に配線３で接続された端子台４が装置の外郭５の一面に近接して取付けられている（図１，図３参照）。端子台４に関しては、図２や図５に示すように装置の外郭５に取付けなくても、後述する第１のカバー６に取付けてもよい。回路基板２と端子台４は、端子台４の外部配線７との接続部８である挿入孔の有る部分を除いて、外郭５にネジ等の固定手段９で固定される第１のカバー６で全体が覆われている。   In this embodiment, measures are taken to ensure and protect the circuit board mounted on the outer shell of the device that is in trouble when it is installed, removed, maintained, and re-installed. The present invention relates to a blower as shown in FIG. In this blower device, a circuit board 2 electrically connected to an electrical component 1 such as a blower and a terminal block 4 connected to the circuit board 2 by wiring 3 are attached in close proximity to one surface of the outer shell 5 of the device. (See FIGS. 1 and 3). As shown in FIGS. 2 and 5, the terminal block 4 may be attached to the first cover 6 described later without being attached to the outer shell 5 of the apparatus. The circuit board 2 and the terminal block 4 are fixed to the outer shell 5 by fixing means 9 such as screws, except for a portion having an insertion hole which is a connection portion 8 to the external wiring 7 of the terminal block 4. The whole is covered with.

この第１のカバー６の端子台４の外部配線７との接続部８の臨む部分は、開口部１０となっていて、端子台４を装置の外郭５に取付けるもの（図３に示すもの）では第１のカバー６は、底の開放した板金製の六面体の箱形に構成され、固定手段９による固定部は開放した底の端縁に曲げ形成されたフランジ１１である。端子台４を第１のカバー６に取付けるもの（図５に示すもの）では、第１のカバー６は底の開放した板金製の六面体の箱形であるが、その一側は別部品の、内側に曲げ形成された取付け用のフランジ１２を備えた側板１３で構成されている。この第１のカバー６の端子台４の外部配線７との接続部８の臨む部分は、板金製の箱形に構成された別の第２のカバー１４で覆われている。   The portion of the first cover 6 facing the connecting portion 8 with the external wiring 7 of the terminal block 4 is an opening 10 for attaching the terminal block 4 to the outer shell 5 of the apparatus (as shown in FIG. 3). The first cover 6 is configured as a hexahedron box made of sheet metal having an open bottom, and a fixing portion by the fixing means 9 is a flange 11 formed by bending at an edge of the open bottom. In the case where the terminal block 4 is attached to the first cover 6 (shown in FIG. 5), the first cover 6 is a hexahedral box made of sheet metal with an open bottom, but one side is a separate part, The side plate 13 is provided with a mounting flange 12 bent inward. A portion of the first cover 6 facing the connection portion 8 with the external wiring 7 of the terminal block 4 is covered with another second cover 14 configured in a sheet metal box shape.

第２のカバー１４は、ネジ等の固定手段９で独自に着脱可能で、外郭５或いは第１のカバー６に取付けられている。第２のカバー１４は上述したいずれのタイプも、第１のカバー６の固定手段９の少なくとも一つを外から覆い、第２のカバー１４を完全に外さない限り覆われた第１のカバー６の固定手段９を操作することはできないようになっている。第１のカバー６に階層状に第２のカバー１４を取付ける図５に示す省スペースタイプでは、底面は開放していて、端子台４を取付ける面に臨む第２のカバー１４の開放部分の辺縁は、少なくとも直交する二方向、二面にわたって第１のカバー６の外面を外側から抱き込むフラップ状ないしはスカート状のラップ部１５が延ばし出されている。そして、ラップ部１５の一つが第１のカバー６に対する取付部になっている。端子台４に接続された外部配線７は第２のカバー１４に設けられた、難燃性ブッシュの装着された引出口１６から外部に引出される。   The second cover 14 can be attached and detached independently by a fixing means 9 such as a screw, and is attached to the outer shell 5 or the first cover 6. In any of the types described above, the second cover 14 covers at least one of the fixing means 9 of the first cover 6 from the outside, and is covered unless the second cover 14 is completely removed. The fixing means 9 cannot be operated. In the space-saving type shown in FIG. 5 in which the second cover 14 is attached to the first cover 6 in a hierarchical manner, the bottom surface is open and the edge of the open portion of the second cover 14 facing the surface to which the terminal block 4 is attached A flap-shaped or skirt-shaped wrap portion 15 for extending the outer surface of the first cover 6 from the outside extends in at least two directions perpendicular to each other. One of the wrap portions 15 is an attachment portion for the first cover 6. The external wiring 7 connected to the terminal block 4 is drawn out from an outlet 16 provided in the second cover 14 and equipped with a flame retardant bush.

この送風装置によれば、外部配線７との接続操作及び接続解除操作は、第２のカバー１４を外して端子台４の接続部８を呈出させて行うことができる。このとき、回路基板２全体及び回路基板２と端子台４との配線３も全体が第１のカバー６で覆われたままで露出することがなく、操作されたり破損を招いたり、配線作業に伴う鉄線屑等の混入も事実上略完全に回避される。第１のカバー６は、単独では外すことができないため、誤って回路基板２が露呈されてしまうような不具合も回避することができる。第２のカバー１４にラップ部１５を備えたものでは、第１のカバー６への取付けがラップ部１５による位置決め作用により簡単にできる効果もある。また、第１のカバー６と第２のカバー１４の重合する部分については一方の構成を除いて、一重にしたのでその分、材料の低減を図ることができる。   According to this blower, the connection operation and the connection release operation with the external wiring 7 can be performed by removing the second cover 14 and presenting the connection portion 8 of the terminal block 4. At this time, the entire circuit board 2 and the wiring 3 between the circuit board 2 and the terminal block 4 are not exposed while being entirely covered with the first cover 6, and are manipulated, damaged, or accompanied by wiring work. Incorporation of iron wire scraps is virtually completely avoided. Since the 1st cover 6 cannot be removed independently, the malfunction that the circuit board 2 is accidentally exposed can also be avoided. In the case where the second cover 14 is provided with the wrap portion 15, there is an effect that the attachment to the first cover 6 can be easily performed by the positioning action by the wrap portion 15. Further, since the overlapping portion of the first cover 6 and the second cover 14 is made a single layer except for one configuration, the material can be reduced correspondingly.
