Waterproof audio socket

The invention relates to a waterproof audio socket, in particular to a waterproof audio socket with an insulating plate body, which can be watertightly coupled to the body side of the waterproof audio socket, so that moisture and moisture cannot pass through the waterproof audio socket. Infiltrated into an electronic product.

According to the advancement of communication technology and electronic technology, electronic products with various functions, such as mobile phones that enable people to communicate at both ends of the world, can accommodate people listening to music anytime, anywhere, and can help people deal with various Personal Computers, etc., have become indispensable tools for modern people, and different types of electronic products can now be integrated into one another, making it possible to use your mobile phone to listen to music or use your personal computer to make calls. It is no longer a distant dream. Investigate that these electronic products are composed of a number of different precision electronic components. Although these precision electronic components have greatly improved the aforementioned performance of each electronic product, they are most likely to be short-circuited when exposed to water. Corrosion damage due to moisture. Take most of the current electronic products as an example. These electronic products are covered with a beautifully designed outer casing, so as to prevent external dust and moisture from contacting the internal precision electronic components. However, on such electronic products. Because there is an audio socket for the user to plug in the speaker and the earphone, the moisture and moisture of the outside can still invade the inside of the electronic product from the gap in the audio socket, and finally the result in the electronic product. When precision electronic components are exposed to water or moisture, they may be short-circuited or eroded. Therefore, users must always be careful when using these electronic products, in addition to the need to pay attention to whether there are water cups and other water objects around them. When the weather is wet, it is also necessary to avoid the use of such electronic products, or after use, it must be dried (for example, placed in a dehumidification cabinet) to protect the performance and life of the electronic products. Convenience.

At present, in order to prevent moisture and moisture from entering the interior of the electronic products from the audio socket to effectively prevent damage to the precision electronic components, most manufacturers will add a protective cover to the audio socket to not use it. In the audio socket, the protective socket is used to block the audio socket, thereby insulating the outside water from invading the electronic products. Please refer to one of the electronic products 10 (such as a mobile phone) shown in FIG. 1 , and an audio socket is arranged thereon. A splicing slot 11 is defined in the audio jack 1 . A protective cover 101 and a matching hole 102 are disposed on the electronic product 10 adjacent to the audio jack 1 . One end of the protective cover 101 is fixed to the electronic product. 10 is adjacent to the insertion slot 11 and has a first insertion portion 101a and a second insertion portion 101b on one side thereof, and the configuration of the first insertion portion 101a and the insertion slot 11 The configuration of the second engaging portion 101b is matched with the fitting hole 102. Thus, when the audio jack 1 is not used, the user can insert the second embedding portion 101b into the fitting hole 102 so that the first embedding portion 101a can be engaged with the mating slot 11. The fitting is completely shielded from the insertion slot 11 and the protective cover 101 can be firmly attached to the surface of the electronic product 10. In this case, if the user accidentally knocks the water cup when using the electronic product 10 When the electronic product 10 is used when the weather is wet, the moisture and moisture of the outside world are blocked by the protective cover 101, and cannot easily flow into the interior of the electronic product 10 through the insertion slot 11, thereby causing the The internal electronic components of the electronic product 10 are damaged, thereby ensuring the service life of the electronic product 10. However, the protective cover 101 of the audio socket 1 still has some defects in use, which are respectively described as follows:

(1) The problem that the protective cover 101 is loosened: Since the protective cover 101 of the audio socket 1 is made of an elastic material (such as rubber), the user is placed adjacent to the end of the protective cover 101 after long-term use. The deformation of the protective cover 101 may not be flatly attached to the surface of the electronic product 10, and the first insertion portion 101a may not be watertightly closed to the insertion slot 11 so that the first cover portion 101a cannot be closed. The moisture and moisture of the outside can still easily penetrate into the electronic product 10.

(2) The insulating ability of the protective cover 101: although the first engaging portion 101a on the protective cover 101 can be inserted into the insertion slot 11 to prevent external moisture and moisture from entering, if the user is extremely humid When the electronic product 10 is used in the weather, moisture is still infiltrated into the electronic product 10 from the insertion slot 11 during the process of opening and closing the protective cover 101, and complete protection cannot be formed.

Therefore, how to design a waterproof audio socket so that the moisture and moisture of the outside world cannot invade the electronic product through the audio socket, so as to effectively prevent the precision electronic components inside the electronic product from being damaged due to moisture. Moreover, the waterproof effect is not degraded due to long-term use, which is an important problem to be solved by the present invention.
