In engine control devices used in small ships,
Some have a built-in buzzer to notify the driver of engine overheating. As shown in FIGS. 4 and 5 as an example, in a conventional control device of this type, a lever 2 for engine control and various switches 3 are attached to a metal housing 1. There are 4 buzzers.
Furthermore, a power transmission mechanism for transmitting the movement of the lever 2 to the control cable 5 is built in the housing 1. control cable 5
The other end is led to the engine, and this cable 5
Mechanical control of the engine is carried out via the Further, electrical control is performed via a wire harness 6 that connects the engine and a power source. The housing 1 is fixed to a substrate 8, that is, to the hull side, by a plurality of screws 7.

The sound is emitted from the front lid side of this buzzer. For this reason, the front lid of the buzzer is provided with a bending process and a sound emitting hole to increase the sound pressure of the buzzer.

性をもたせていた。 Although the housing 1 has some degree of waterproofing, since control devices for small boats mainly used at sea are constantly exposed to seawater, some seawater may enter the housing 1. Intrusion is inevitable. For this reason, it is desirable to wrap the buzzer 4 with a waterproof member such as a rubber cover, but if the front cover of the buzzer is covered with a cover, the sound pressure will decrease, so a cover cannot be attached to the front cover of the buzzer. Therefore, the conventional buzzer front cover has been made of a plated steel plate or coated with a coating to provide rust prevention properties.

However, since the housing 1 is a die-cast product made of aluminum or zinc and is electrically conductive, if even a small amount of seawater enters between the inner surface of the housing 1 and the buzzer 4, a current will flow, which is worse than normal rust. Causes rapid galvanic corrosion. In particular, the lead wire of the buzzer 4 is constantly energized, and the electrical ground of the small ship's engine is the ship's hull, to which the conductive housing 1 is fixed with metal screws 7. For these reasons, when moisture such as seawater adheres between the buzzer 4 and the housing 1, a leakage current flows from the buzzer 4 to the housing 1, causing early loss of function of the buzzer 4 due to electrolytic corrosion. Note that a buzzer with a plated front cover made of steel plate is itself an electrical conductor, so leakage current is likely to flow through it. In addition, even if a steel plate is painted, if a part of the paint peels off even slightly or if there is a defective paint spot near the sound hole, the housing may become damaged due to the presence of moisture.
Leakage current tends to flow between the If even a small amount of leakage current begins to flow, the above-mentioned material itself has a weak anti-corrosion ability, so electrolytic corrosion rapidly progresses, eventually leading to loss of functionality.

In the buzzer assembly having the above configuration, the outer side of the buzzer body case, which does not affect the buzzer sound pressure, is covered with a rubber cover and is therefore waterproof. The front lid of the buzzer, which affects the sound pressure of the buzzer, is made of the non-conductor coated metal plate described above instead of being covered with a rubber cover, thereby making the front lid itself non-conductive and improving rust prevention. enhance In addition, this buzzer assembly is supported by the housing via a rubber cover with the front cover separated from the inner surface of the housing, and the entire circumference of the flange-shaped part that connects the front cover and the buzzer body case, as well as the buzzer The entire circumference of the main body case is watertightly covered by the rubber cover. This prevents leakage current from flowing from the buzzer to the housing even if moisture such as seawater gets into the housing. In this case, the front lid side does not need to be covered with a rubber cover, so the buzzer sound pressure does not decrease.

As described above, according to the present invention, even if moisture such as seawater enters the housing of an engine control device with a built-in buzzer used for small ships, conductors such as water droplets will not adhere to the front cover and the housing. Since direct adhesion to the buzzer body case is avoided, leakage current that causes electrolytic corrosion can be prevented from flowing between the buzzer and the housing, which is highly effective in suppressing the occurrence and progression of corrosion. In addition, the manufacturing process is simple because there is no need for plating or painting after processing or assembling the parts of the buzzer front cover.
