関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to stationary electronic equipment equipped with electronic circuits, power supply circuits, etc. inside the cabinet, and particularly to equipment having an opening on the top surface. This invention relates to a device for preventing liquid inflow.

ある。Conventional configuration and its problems When an electronic device has an opening on the top, if liquid is accidentally spilled on the top of the electronic device, it will flow inside through the opening on the top and damage the printed wiring board. Because it penetrates into the upper circuit, it may cause short circuits and malfunctions.
従来の電子機器では、この対策として、下方に電子部品
がない場所の天面にのみ開口を開けるか。As a countermeasure for conventional electronic equipment, is it possible to open an opening only on the top surface where there are no electronic components below?

を得ない場合も出てきている。また、機能の追加等によ
り天面に開口部が必要になる場合もある。Alternatively, they tried to eliminate openings on the top as much as possible0 However, as electronic devices have become smaller in recent years, they are at a disadvantage in terms of internal temperature rise9, making it necessary to open heat dissipation holes on the top. There are cases where there is none. Additionally, an opening may be required on the top surface due to additional functions.

とを目的とする。Purpose of the Invention The present invention solves the above-mentioned conventional problems, and prevents malfunctions by preventing liquid from entering electronic circuits, power supply circuits, etc. even if liquid flows in from the opening in the top surface. An object of the present invention is to provide a liquid inflow prevention device that prevents short circuits and the like.
発明の構成
前記目的を達成するため、本発明においては、天面開口

る。FIG. 4 shows an example in which the adjustment hole 2 and signal passing window a of a variable resistor etc. are implemented, and shows a sectional view taken along the line D--D in FIG. 1. The liquid guiding rib 5b is necessary when liquid flows in from the signal passage window 3, and the liquid guide rib 5C is necessary when liquid flows in from the adjustment hole 2 of a variable resistor or the like. Its function is similar to that of the liquid guiding rib 6a.
