しかしながら、外部配線５３を防水ケース等に引き込むため、現場で用意された外部配線５３の種類やサイズおよび施工品質レベルにより、引き込み口における防水性能が保たれないことがあり、防水ケースが浸水し不具合を引き起す可能性があった。また上記別の従来例では結線ボックスが地中に埋設されているため、結線部分での電気特性の確認が困難である。   However, since the external wiring 53 is drawn into the waterproof case or the like, the waterproof performance at the drawing-in port may not be maintained depending on the type and size of the external wiring 53 prepared at the site and the construction quality level. Could cause. In the other conventional example, since the connection box is buried in the ground, it is difficult to confirm the electrical characteristics at the connection portion.

したがって、この発明の目的は、外部配線にかかわらず安定した防水性能を確保することができるとともに防水ケースの内部で電気配線および電気特性の点検を行うことができる防水器具を提供することである。   Accordingly, an object of the present invention is to provide a waterproof device that can ensure stable waterproof performance regardless of external wiring and can check electrical wiring and electrical characteristics inside the waterproof case.

この発明の防水器具は、防水ケースが点検口を有するとともに防水処理された電線引き出し口を有する。カバーは前記点検口を着脱自在に密閉する。電線は前記電線引き出し口より外部に引き出されて外部配線と防水結線される。点検用端子は前記防水ケース内で前記電線に接続されて前記点検口より点検可能である。   In the waterproof device of the present invention, the waterproof case has an inspection opening and a wire drawing opening that is waterproof. A cover detachably seals the inspection port. The electric wire is drawn out from the electric wire outlet and is waterproofly connected to the external wiring. The inspection terminal is connected to the electric wire in the waterproof case and can be inspected from the inspection port.

上記構成において、前記電線は絶縁被覆を有し、前記防水ケース内で前記電線の心線が露出した前記絶縁被覆の端部に防水性絶縁材を含浸している。   The said structure WHEREIN: The said electric wire has insulation coating and the waterproof insulation material is impregnated in the edge part of the said insulation coating in which the core wire of the said electric wire was exposed in the said waterproof case.

この発明の防水器具によれば、防水ケースの電線引き出し口は特定の電線のみが引き出され、その外部で外部配線と接続するため、電線引き出し口での防水性能を安定して保つことができ、外部配線の種類やサイズおよび施工品質レベル等の影響を受けない。しかも施工後に防水ケースの内部で防水ケースを取り出すことなく配線の電気特性を確認する作業が行える。   According to the waterproof device of the present invention, only a specific electric wire is drawn out from the wire outlet of the waterproof case, and since it is connected to the external wiring outside thereof, the waterproof performance at the wire outlet can be stably maintained. Not affected by the type and size of external wiring and construction quality level. Moreover, it is possible to check the electrical characteristics of the wiring without taking out the waterproof case inside the waterproof case after construction.

電線の絶縁被覆の内端部を防水性絶縁材料で含浸することにより心線の内部を伝って防水ケース内が浸水することを防止することができる。   By impregnating the inner end portion of the insulating coating of the electric wire with a waterproof insulating material, it is possible to prevent the inside of the waterproof case from being flooded through the inside of the core wire.

この発明の一実施の形態を図１から図６により説明する。この防水器具は、地中に埋設する地中埋設器具であり、防水ケース１内にはソケット台１３に取付けられたランプソケット２および反射板４を配置し、ランプソケット２にランプ３を装着し、またランプソケット２の接続線２ａが接続された点検用端子６を防水ケース１内に配置している。   An embodiment of the present invention will be described with reference to FIGS. This waterproof device is an underground device embedded in the ground. In the waterproof case 1, a lamp socket 2 and a reflector 4 attached to a socket base 13 are arranged, and a lamp 3 is attached to the lamp socket 2. The inspection terminal 6 to which the connecting wire 2a of the lamp socket 2 is connected is arranged in the waterproof case 1.

防水ケース１の上面の地面５に露出する部分は射光穴を兼ねた点検口７を設け、点検口７を透光カバー８で着脱自在に密閉している。防水ケース１の外殻の側部には防水パッキン２２により防水処理された電線引き出し口９を設け、この電線引き出し口９を覆うように外殻の外側に補助ケース１０を設け、補助ケース１０に外部配線引き込み口１１を設けている。補助ケース１０は防水ケース１とともに地中に埋設される。外部配線引き込み口１１には外部配線１４を通す電線管１６の端部が接続され、外部配線１４が補助ケース１０の内部に通される。   A portion exposed to the ground surface 5 on the upper surface of the waterproof case 1 is provided with an inspection port 7 that also serves as a light emitting hole, and the inspection port 7 is detachably sealed with a translucent cover 8. A wire lead-out port 9 waterproofed by a waterproof packing 22 is provided on the side of the outer shell of the waterproof case 1, and an auxiliary case 10 is provided outside the outer shell so as to cover the wire lead-out port 9. An external wiring lead-in port 11 is provided. The auxiliary case 10 is buried in the ground together with the waterproof case 1. An end of a conduit 16 through which the external wiring 14 is passed is connected to the external wiring drawing port 11, and the external wiring 14 is passed through the auxiliary case 10.

防水処理された電線引き出し口９には電線１２が挿通される。電線１２は絶縁被覆１２ａを有し、外端部が補助ケース１０内で外部配線１４と防水結線部１５で防水結線される。このため、補助ケース１０は防水構造としてもしなくてもよい。防水ケース１内の電線１２の心線１２ｂが露出した絶縁被覆１２ａの端部に防水性絶縁材を含浸し、この含浸部１２ｃにより、結露等によって心線１２ｂを伝って外部から浸水するのを防止することができる。外部配線１４と電線１２の各３本のうち１本はアース線であり、点検用端子５とランプソケット２間では１本の接続線２ｂがソケット台１３と接続されている。   An electric wire 12 is inserted into the waterproof wire outlet 9. The electric wire 12 has an insulating coating 12a, and the outer end portion is waterproof-connected in the auxiliary case 10 by the external wiring 14 and the waterproof connection portion 15. For this reason, the auxiliary case 10 may or may not have a waterproof structure. The end portion of the insulation coating 12a where the core wire 12b of the electric wire 12 in the waterproof case 1 is exposed is impregnated with a waterproof insulating material. Can be prevented. One of the three wires of the external wiring 14 and the electric wire 12 is a ground wire, and one connecting wire 2 b is connected to the socket base 13 between the inspection terminal 5 and the lamp socket 2.

点検用端子６は充電部が露出しており、端子台１８に取付けられている。この場合、点検用端子６を絶縁カバーで覆って充電部を露出可能にしてもよい。   The charging terminal of the inspection terminal 6 is exposed and is attached to the terminal block 18. In this case, the charging terminal may be exposed by covering the inspection terminal 6 with an insulating cover.

図４から図６は防水器具の詳細図であり、ランプソケット２を支持するソケット台１３および反射板４はフレーム２０に取付けられて、透部カバー８を開いた点検口７から反射板４等の付いたフレーム２０を取り出すことができ、これにより点検口７から点検用端子６を用いて電気特性の確認を容易に行うことができる。また補助ケース１０は外部配線引き込み口を両側に形成し、これらに外部配線１４の電線管１６を接続し、外部配線１４の一方を電源入力側とし、他方を電源送り側としている。   4 to 6 are detailed views of the waterproof device. The socket base 13 and the reflecting plate 4 that support the lamp socket 2 are attached to the frame 20, and the reflecting plate 4 and the like are opened from the inspection port 7 in which the transparent cover 8 is opened. The frame 20 with the mark can be taken out, whereby the electrical characteristics can be easily confirmed from the inspection port 7 using the inspection terminal 6. Further, the auxiliary case 10 has external wiring lead-in ports formed on both sides thereof, and the conduit 16 of the external wiring 14 is connected to them, and one of the external wirings 14 is a power input side and the other is a power supply side.

この実施の形態によれば、防水ケース１の埋設後は防水接続部１５が地中に埋設されているため、この部位での電気特性確認作業は困難であるが、防水ケース１内に点検用端子６を設けているため、施工後や運用中において透光カバー８を開き電気特性を容易に確認することができる。また防水ケース１内に外部配線１４が引き込まれていないため防水性の高い器具構造が実現される。   According to this embodiment, after the waterproof case 1 is embedded, the waterproof connection portion 15 is embedded in the ground, so that it is difficult to check the electrical characteristics at this site. Since the terminal 6 is provided, the translucent cover 8 can be opened and the electrical characteristics can be easily confirmed after construction or during operation. Moreover, since the external wiring 14 is not drawn into the waterproof case 1, a highly waterproof instrument structure is realized.

さらに、点検用端子６の電線接続を着脱可能にすると、万一施工時に電線１２と外部配線１４と防水結線において、誤結線が生じても施工後に点検用端子６で電線１２を振り替え接続することができるため、容易に正常な配線に修正することができる。   Furthermore, if the wire connection of the inspection terminal 6 is made detachable, even if an incorrect connection occurs in the waterproof connection between the electric wire 12 and the external wiring 14 at the time of construction, the electric wire 12 can be transferred and connected by the inspection terminal 6 after the construction. Therefore, it can be easily corrected to normal wiring.
