BACKGROUND OF THE PRESENT INVENTION
Field of Invention
The present invention relates to a switch waterproof structure, in particular to the blocking portions are formed after a waterproof material is injected into the grooves of the body, the grooves of the plugger and the grooves of the pin, wherein the blocking portions are closely attached to the supporting parts of the body, the supporting parts of the plugger and the supporting parts of the pin, so as to achieve the best waterproof function and prolong the service life of the switch, and the plugger is easy to position, which can save manufacturing time.
Description of Related Arts
It is noted that a general switch 1 (such as a toggle switch), as shown in FIG. 1, mainly includes a body 10, which has a injected part 100 and an inclined surface 101 respectively arranged on a top thereof. The body 10 has a injected hole 102 arranged in the middle thereof, and a threaded portion 103 arranged on a bottom thereof. The threaded portion 103 has pin hole 104 correspondingly arranged on two sides thereof. A pin 11 is fixed in the pin hole 104. The pin 11 extends through a perforation 120 of a plugger 12. The plugger 12 has a connecting end 121 arranged above thereof, and a tip 122 arranged on a bottom thereof. An embossing pattern 123 is provided between the tip 122 and the perforation 120. The plugger 12 is integrally formed. When a hot-melt waterproof material 13 is injected, the waterproof material 13 will cover the injected part 100, the inclined surface 101, the inner wall of the injected hole 102, the outer wall of the plugger 12 and the pin 11 to form a waterproof effect of a membrane. However, the injected part 100, the inclined surface 101, the inner wall of the injected hole 102, the outer wall of the plugger 12 and the pin 11 are not provided with grooves to support the waterproof material 13, so when the switch 1 is in use, the waterproof material 13 is likely to peel off to form a gap, resulting in water leakage and damage. In addition, the plugger 12 is integrally formed, when injecting the hot-melt waterproof material 13, it will be difficult to locate the tip 122 of the plugger 12, which will prolong the manufacturing time and be quite inconvenient.
