New description: [New technical field] This is a kind of chassis for communication signal receiving equipment, especially for people who can effectively prevent water or dust from entering the chassis. [Prior Art] In the daily life of our people, the application of various wired communication devices (such as telephones) is extremely rampant, and due to the continuous advancement of technology, the data transmission speed of the letter equipment has also been continuously improved. It is the control of the precision requirements and environmental conditions of the components. In addition to the thermal operation of the product operation, the most basic one is to avoid the invasion of water or dust, so as to avoid the deterioration of internal components caused by the humid and dusty environment. Deteriorating, thus affecting the normal operation of the product and making money; and the signal access equipment used to connect the money transmission of various communication devices, because it is placed outdoors, it will inevitably be exposed to wind, sun and rain. In the environment, the opportunity of water or dust intrusion is increased. Therefore, the design of the housing structure (ie, the outer casing) needs to consider the waterproof and dustproof performance. Figure 1 to Figure 3 are respectively a perspective view of the chassis of the conventional communication signal receiving device, a side view of the cover and a partial enlarged view. As shown in the figure, the chassis of the conventional k-signal receiving device comprises: a box body 10, a cover body 20 and an elastic loop 3〇, wherein the box body 1 is for receiving various related signal transmission devices, and a plurality of signal connections are respectively arranged on the circumferential side of the box body 10. a hole 103 and a latching portion 102 are provided, and a flange 104' is disposed on the outer peripheral edge of the opening of the casing 1 , and an outer protruding portion M378604 abutting portion 105 is disposed on the outer peripheral side of the flange 104, and A first ring groove 106 is disposed on a top side of the first abutting portion 105. The cover body 20 is fastened to the side of the casing 10 by at least one splicing portion 201 for covering the casing. 10, the outer peripheral side of the flange 104 adjacent to the opening, and the cover body 20 is provided with a lock head 202' at a position corresponding to the lock portion 1〇2 for locking the box body 10 and the cover body 2, A second ring portion 204 is disposed on the bottom surface of the cover body 2, and a second ring groove 204 is disposed on the bottom surface of the second abutting portion 203. A ring groove φ 106 ′ and the first ring groove 106 and the second ring groove 204 are oppositely engageable with the elastic washer 30. The signal access holes 103 are used to extend the external signal lines into the casing 10 to facilitate connection of various related signal transmission devices, and are also implemented between various signal lines and signal connection holes 1 and 3. The filling is sealed to prevent moisture and dust from penetrating into the casing 1 by its gap, and the cover 20 can be pivoted by the hinge portion 2〇1 to cover the casing 1〇. The opening 20' is coupled to the locking portion 102 via the locking head 202 to form a locking state with the casing 10. At this time, the second ring groove 204 of the cover 20 can be matched. The first ring groove 106 of the casing 10 presses the elastic washer 30 against each other, so that the elastic washer 3 is elastically deformed and filled at the joint between the casing 1 and the cover 20 to form a seal. It produces a basic waterproof and dustproof effect; however, this structure has the following drawbacks in practical use: '丨, since the casing 10 and the cover 20 are manufactured with manufacturing tolerances, the spliced portion 201 is twisted. There is also a set of tolerances when the casing 10 and the cover are connected, and the accumulation of such tolerances is easy to make. The cassette 10 5 M378604 gap closing body 20 and the rear cover, which is also likely to cause dust or water into the enclosure through the gap side. 2. Since the gap between the joint portion of the casing 10 and the lid body 20 is exposed to the outside, rainwater and wind sand are easily infiltrated by the joint slit and gradually enter the casing. 3. Since the box body 10 and the cover body 20 are subjected to a relative pressing force, distortion deformation occurs, and the elastic washer 30 is mostly made of rubber material, and the deformation amount is not good when compressed, and is often unable to be effectively absorbed. The deformation of the casing 10 and the cover 20 when subjected to a force causes * to have a gap that cannot be filled, thereby providing a space for rain and dust to penetrate. 4. When assembling, since the elastic washer 30 must be disposed in the first ring groove 106 of the case 10 or the second ring groove 204 of the cover body 20, assembly is inconvenient, and due to the elastic washer 30 Lack of effective positioning, it will fall off when it is easy to use, resulting in a lack of application. φ Therefore, how to create a chassis for a communication signal access device to effectively prevent water or dust from entering the chassis will be actively exposed by the author. [New content] In view of the lack of the prior art, one of the aims of the present invention is to provide a chassis for a communication signal receiving device, which forms a first protection structure by a side bank to prevent water or dust from entering the chassis. . 6 M378604 Another object of the present invention is to provide a chassis for a communication signal receiving device, which is formed by a first elastic washer, a second elastic washer or a first elastic washer and a second elastic washer to form a second protective structure to prevent Water or dust enters the chassis.
