[0021] Figure 3 It is a schematic structural view of another perspective of the split state of the gasket and the sealing plate of the outdoor antenna signal processing device. Specific embodiments

[0022] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0023] As Figure 1 and 2 shown, this embodiment provides an outdoor antenna signal processing device, which includes a housing 1 and an integrated circuit board 2 arranged inside the housing 1. A plurality of antenna connectors are arranged on the integrated circuit board 2, and receiving holes 3 are opened at positions of the housing 1 corresponding to the antenna connectors.

[0024] As Figures 1 to 3 shown, the bottom side wall of the housing 1 is an access end face 11 for the transmission line to access the integrated circuit board 2.

[0025] A plurality of heat dissipation fins 4 for increasing the heat dissipation surface area are provided on both the front side wall and the rear side wall of the housing 1. The areas of the front and rear side walls of the housing 1 are larger than those of other side walls, so that the proportion of the heat dissipation fins 4 is maximized to improve the heat dissipation efficiency of the device.

[0026] As Figure 2 shown, the receiving holes 3 are opened on the front side wall of the housing 1. A plurality of heat dissipation fins 4 are provided with relief grooves 5 at positions corresponding to the receiving holes 3, and the wall surface around the outside of the receiving holes 3 is the groove bottom of the relief grooves 5. An annular shielding plate 31 is fixed on the hole wall of the receiving holes 3. The shielding plate 31 protrudes from the receiving holes 3. The receiving holes 3 are equipped with a sealing plate 6. The sealing plate 6 covers the receiving holes 3 and is fixed in the relief grooves 5. As Figure 3 shown, a circle of abutting rings 61 is fixed on the inner side surface of the sealing plate 6. The abutting rings 61 are matched with the shielding plate 31 and are sleeved outside the shielding plate 31. By providing the shielding plate 31 in the receiving holes 3 and simultaneously providing the abutting rings 61 that can be sleeved outside the shielding plate 31 in the sealing plate 6, the path for rainwater to enter the receiving holes 3 through the sealing plate 6 is increased, and the sealing performance of the sealing plate 6 for the receiving holes 3 is improved. In addition, the device is vertically installed on the support with the access end face 11 facing downwards. Under the action of gravity, rainwater will flow downwards. Therefore, even if rainwater enters the relief grooves 5 and contacts the shielding plate 31, the water flow will flow down along the shielding plate 31. That is, the shielding plate 31 is equivalent to a rainwater guiding plate, which plays a role in guiding the rainwater away from the receiving holes 3 and further improving the waterproof performance of the receiving holes 3.

[0027] Preferably, the sealing plate 6 is a transparent plate, which can facilitate operators to monitor the device, find problems in time, and repair them in time, thereby extending the service life of the device to a certain extent.

[0028] like Figures 1 to 3 As shown, in a preferred embodiment, a circle of integral ring 7 is fixed on the outside of the clearance groove 5, and the sealing plate 6 is located inside the integral ring 7. The outer surface (i.e., the front side) of the integral ring 7 is flush with and connected to the outer side of the sealing plate 6. By providing the integral ring 7 that is flush with and connected to the sealing plate 6, the sealing performance of the sealing plate 6 to the receiving hole 3 is further improved. Moreover, if the integral ring 7 is not provided, rainwater on the upper side may flow along the channel between the adjacent heat dissipation fins 4 to one side of the upper side of the shielding plate 31, forming water accumulation and bringing hidden dangers. The integral ring 7 is wrapped around the entire periphery of the receiving hole 3, which can eliminate such problems from the root. In addition, the integral ring 7 can also locate the installation position of the sealing plate 6, which is convenient for installing the sealing plate 6.

[0029] The outer surface of the integral ring 7 is flush with the outer end surface of the heat dissipation fin 4 .

[0030] Furthermore, a drainage groove 71 is provided at the bottom of the integral ring 7, one end of the drainage groove 71 is connected to the clearance groove 5, and the other end is connected to the channel between adjacent heat dissipation fins 4, that is, the space between the integral ring 7 and the baffle plate 31 is connected to the outside, so that rainwater entering the clearance groove 5 can be discharged. (Specifically, due to the setting of the integral ring 7, there is a storage space between the integral ring 7 and the baffle plate 31. Although the sealing plate 6 is flush with and connected to the integral ring 7, a small amount of rainwater may still enter the storage space. Therefore, by setting the drainage groove 71, the storage space in the integral ring 7 can be opened up, and at the same time, the channel between adjacent heat dissipation fins 4 can be used to discharge rainwater in an orderly manner. Moreover, the heat dissipation fins 4 are used for heat dissipation, and rainwater passing through the channel between adjacent heat dissipation fins 4 is more conducive to the heat loss of the heat dissipation fins 4.

[0031] like Figure 2 and 3 As shown, in a preferred embodiment, a flexible annular sealing gasket 62 is placed between the abutting ring 61 of the sealing plate 6 and the clearance groove 5. During the process of fixing the sealing plate 6 and the clearance groove 5, the flexible sealing gasket 62 can fill the gap between the clearance groove 5 and the sealing plate 6, thereby further increasing the difficulty of rainwater entering the receiving hole 3.

[0032] Regarding the fixing method of the sealing plate 6, Figure 2 and 3As shown, in a specific embodiment: a plurality of fixing holes 51 are provided at the bottom of the give way groove 5. A plurality of connecting holes 63 are provided at positions of the sealing plate 6 corresponding to the fixing holes 51. A plurality of through holes 64 are provided at positions of the sealing gasket 62 corresponding to the fixing holes 51. The fixing holes 51 and the connecting holes 63 are threaded holes. A fixing bolt 65 is threadedly connected to the corresponding fixing holes 51 and the connecting holes 63, and the fixing bolt 65 passes through the corresponding through hole 64. That is, by providing threaded holes on the give way groove 5 and the sealing plate 6, and cooperating with the corresponding fixing bolt 65, the sealing plate 6 is fixed in the give way groove 5. The sealing plate 6 is detachably fixed to the housing 1 by the fixing bolt 65. When the operator needs to inspect the antenna, he only needs to remove the fixing bolt 65 and then remove the sealing plate 6.

[0033] Furthermore, the fixing hole 51 is a non-through hole 64 , and its inner end is arranged in the front side wall of the shell 1 , that is, the fixing hole 51 does not penetrate the front side wall of the shell 1 to avoid the possibility of water entering therethrough and will not affect the sealing of the shell 1 .

[0034] like Figure 1 As shown, the access end face 11 is provided with a waterproof breathable valve 8 connected to the housing 1. Since the entire housing 1 has extremely high sealing performance, temperature changes in the external environment will cause changes in the air pressure in the housing 1, and the changes in the air pressure in the housing 1 will be applied to the integrated circuit board 2, and the provision of the waterproof breathable valve 8 can balance the air pressure in the housing 1.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
