1. Field of Invention
The present invention relates to a waterproof housing. More particularly, the present invention relates to a waterproof housing of electronic components, which is applicable to an outdoor antenna to prevent the antenna from being wet by external liquid.
2. Related Art
Currently, various antennae are available, which are roughly classified into indoor antennae and outdoor antennae. Taking an outdoor antenna as an example, it must be considered that when the antenna structure is installed outdoors for use, electronic components inside a casing must be protected from being invaded by rain water or other liquid, so as to avoid the damage of the electronic components disposed in the casing. Therefore, for the outdoor antenna, the waterproof function is one of the indispensable and important conditions.
A common conventional outdoor antenna structure has a housing formed by combining an upper casing and a lower casing and locking with screws, such that an accommodation space capable of accommodating the electronic components inside the casings is formed. However, the rain water likely penetrates into the casings through a combination gap between the two casings, and resulting in the damage of the internal parts. Therefore, when assembling a conventional antenna structure, an O ring is generally installed between the upper casing and the lower casing additionally, and a waterproof adhesive is filled into gaps between the O ring and the casings fully to have a waterproof function, so as to protect the internal parts from water. Additionally, a plastic material can be perfused by injection molding, so as to fill the gaps between the external casing and the electronic components fully, such that the electronic components are wrapped in the external casing by the plastic material, thereby achieving the waterproof purpose of the outdoor antenna.
However, regardless the waterproof adhesive wrapping the joint of the housing or the plastic material filled in the casing and wrapping the electronic components, after a long term of using, the materials are likely to be cracked and fall off due to the deterioration, such that the rain water will penetrate into the housing through deteriorated regions and cause undesired influence on the electronic components, thereby reducing the efficacy and working life of the outdoor antenna structure.
Furthermore, in the conventional antenna waterproof structure, a large number of screws are required for locking during assembling and disassembling the antenna, and thus the assembling process is complicated and time-consuming. In addition, a large amount of waterproof adhesive or plastic material is required during the manufacturing process, such that the manufacturing cost is significantly increased, which does not meet the needs of economic benefits.
In view of the above problems, the present invention provides a waterproof housing to solve the problem in the prior art that external liquid, such as rain water, likely penetrates into the inner space of an outdoor antenna and thus damaging electronic components of the antenna device.
The present invention provides a waterproof housing for accommodating an antenna structure having a plurality of electronic components. The waterproof housing includes a casing and a base body. The casing has an accommodation space therein, an opening corresponding to the accommodation space and opened a downward opening, and a plurality of combination holes disposed near to the opening. The base body is selectively disposed on the opening and has a fixing plate and a plurality of combination members corresponding to the combination holes. The fixing plate is used to hold the electronic components of the antenna, and the position of the fixing plate is higher than the positions of the combination members. The combination members further each have an elastic portion and a snapping portion extending from the elastic portion. When the base body is disposed on the opening, the snapping portions of the combination members are combined with the combination holes, and the positions of the electronic components accommodated in the casing are higher than those of the combination holes.
The advantage of the present invention lies in that, the positions of the electronic components accommodated in the casing are higher than those of the combination holes, when external liquid, such as rain water, penetrates into the casing through the combination holes, the rain water will flow down into the base body due to the gravity, such that the electronic components are prevented from being wet and resulting in short circuit, and even being damaged. The casing and the base body are joined by snapping the combination holes and the combination members and can be disassembled without any auxiliary tools, and thus the installation process is fast and simple.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:
The combination members 122 further each have an elastic portion 1221 and a snapping portion 1222 extending from the elastic portion 1221. When the base body 120 is selectively disposed on the opening 111 of the casing 110, the snapping portion 1222 and the combination hole 112 of the casing 110 are snapped together, and the elastic portion 1221 provides an elastic force, such that the snapping portion 1222 is kept in a snapped state. At the same time, the positions of the electronic components 200 accommodated in the casing 110 are higher than those of the combination holes 112. The snapping portion 1222 and the combination holes 112 are closely combined due to the elastic force of the elastic portion 1221. When the rain water is splashed on the outer side of the waterproof housing 100, the snapping portions 1222 snapped in the combination holes 112 prevent the rain water from entering the casing 110. If the rain water flows into the casing 110 through the combination holes 112 accidentally, as the positions of the electronic components 200 are higher than those of the combination holes 112, the electronic components 200 will not be wet by the rain water to be damaged.
Please refer to
When the base body 120 is disposed on the opening 111 of the casing 110, the positions of the baffles 1232 are higher than those of the combination holes 112, such that no combination hole 112 exits at the position of the middle region of the through hole 1233 corresponding to the position of the casing 110. The rain water entering through the combination holes 112 accidentally will flow into the other two regions and then flow to the outside through the drain holes 1231, thus preventing the rain water from penetrating through the combination holes 112 to damage the signal connection line 210. If the rain water accidentally flows into the regions having the through hole 1233, the rain water will be discharged through the through hole 1233.
As shown in
Referring to
The waterproof housing of the present invention is used for dispose an outdoor antenna device, and the positions of the antenna components disposed in the casing are higher than those of the combination holes of the casing, such that the rain water penetrated inside through the combination hole will flow downwards due to the gravity, and thus the electronic components will not be wet by the rain water to be damaged. The casing and the base body of the present invention are combined by snapping the combination members and the combination holes. The combination members not only have the function of water proofing, but also can be assembled or disassembled without using a screwdriver or any auxiliary tools, and thus the manufacturing cost is low, and the use convenience is significant improved.
