Some devices can replace the antenna inside the device, but the antenna is easily scratched and damaged by other devices inside the device during the process of mounting and dismounting the antenna.

In order to solve the above problems, the present utility model provides a network device, as shown in fig. 1 to 12, which can conveniently replace an antenna so that the device can be adapted to different scenes, and which can also protect the antenna from damage during the replacement process.

As shown in fig. 1, 2 and 4, specifically, the network device includes a housing 1, a circuit board 2, a support assembly 3 and an antenna assembly 4, wherein: the housing 1 is provided with a mounting cavity 111 and an opening 112 communicated with the mounting cavity 111; the circuit board 2 is arranged on the inner wall of the mounting cavity 111; the support assembly 3 comprises a mounting seat 31 which can be inserted into the mounting cavity 111 through the opening 112, and the mounting seat 31 is provided with an avoidance hole 311; the antenna assembly 4 is disposed on one side of the mounting seat 31 away from the circuit board 2, and the antenna assembly 4 can be synchronously inserted into the mounting cavity 111 along with the mounting seat 31 and electrically connected with the circuit board 2 through the avoidance hole 311.

In the network device provided by the embodiment of the utility model, the antenna component 4 can be independently replaced, so that the replacement cost can be reduced, the network device can be suitable for various different environments, and the application range is wide. When the antenna assembly 4 needs to be replaced, the mounting seat 31 is controlled to be separated from the mounting cavity 111 along the-X axis direction from the opening 112, the old antenna assembly 4 in the network equipment can be synchronously separated from the mounting cavity 111 along with the mounting seat 31 and disconnected with the circuit board 2, then a new antenna assembly 4 is synchronously inserted into the mounting cavity 111 along the +X axis direction along with the mounting seat 31 through the opening 112, so that the new antenna assembly 4 is electrically connected with the circuit board 2 through the avoiding opening 311, and when the antenna assembly 4 is installed or detached, only the mounting seat 31 needs to be controlled to be inserted into or separated from the mounting cavity 111, no extra step is needed, and the operation is simple and convenient. In addition, since the antenna assembly 4 is located at one side of the mounting seat 31 away from the circuit board 2, other elements on the circuit board 2 can not be in direct contact with the antenna assembly 4 except that the circuit board 2 can be electrically connected with the antenna assembly 4 through the avoiding opening 311, so that the mounting seat 31 can also play a role in protecting the antenna assembly 4, and the problems of falling off or short circuit of the elements and the like caused by scratch damage of the antenna assembly 4 are avoided.

The mounting seat 31 may be a hard insulating member such as a plastic member, so that the supporting strength of the antenna assembly 4 is ensured, and meanwhile, the phenomenon of short circuit and the like of the antenna assembly 4 can be avoided.

When the antenna assembly 4 needs to be replaced, the cover 12 is detached from the housing 11, so that the opening 112 is exposed; after the replacement, the cover 12 is mounted on the housing 11 and covers the opening 112. The cover body 12 can protect other elements in the housing 1 such as the antenna assembly 4 and the support assembly 3, and the like, so as to prevent the antenna assembly 4 and the support assembly 3 from accidentally falling out of the mounting cavity 111; and meanwhile, the influence of external water vapor or dust and the like entering the mounting cavity 111 on the normal operation of other elements inside the shell 1 such as the antenna assembly 4 and the circuit board 2 can be avoided.

And the antenna assembly 4 is assembled and disassembled without external tools through the limit of the slot, so that the operation is simple and convenient. Of course, in other embodiments, the limiting structure 32 may be other structures such as a buckle, a screw, etc. capable of detachably fixing the antenna assembly 4 on the mounting seat 31, so long as the contact 411 of the antenna assembly 4 is guaranteed to be capable of corresponding to the avoiding opening 311, and the embodiment of the present utility model is not limited in particular herein.

When the antenna assembly 4 on the mounting seat 31 needs to be replaced, the old antenna assembly 4 on the mounting seat 31 slides along the-Y axis direction to be separated from the slot, then a new antenna assembly 4 slides along the +Y axis direction to be inserted into the slot, at this time, the antenna assembly 4 can be propped against the first limiting piece 321 to limit the insertion position of the antenna assembly 4 on the mounting seat 31, so that the antenna assembly 4 is prevented from sliding further along the +Y axis direction, and the contact 411 can correspond to the avoidance port 311 after the antenna assembly 4 is inserted, so that a user can conveniently install the antenna assembly 4.

The first limiting part 321 may be a U-shaped structure, which can limit the sliding of the antenna assembly 4 along the +y axis direction, and limit the sliding of the antenna assembly 4 along the +z axis direction. In this way, in the assembled state, the limiting structure 32 can avoid the antenna assembly 4 from shifting relative to the mounting seat 31 along the directions except the-Y axis, and ensure the stability of the antenna assembly 4 on the mounting seat 31.

As shown in fig. 7 to 8, the limiting structure 32 can limit the antenna assemblies 4 having different transmit/receive powers or different sizes along the ±y axis directions, so that the range of use of the network device can be enlarged.

The pin header 43 is used to fix the first antenna 41 and the second antenna 42, and enables communication connection of both. The first antenna 41 and the second antenna 42 are arranged in a stacked manner with the mounting seat 31, so that the mounting seat 31 can cover the antenna assembly 4 as much as possible, the problems that the antenna assembly 4 is scratched and damaged by the circuit board 2 or other elements in the mounting cavity 111 to cause the elements to fall off or short circuit and the like are avoided, the whole volumes of the support assembly 3 and the antenna assembly 4 can be prevented from being increased, and the support assembly 3 and the antenna assembly 4 are prevented from occupying a larger space in the housing 1. Of course, the antenna assembly 4 may also include an antenna or multiple antennas, as desired, stacked or side-by-side, and secured by the pin header 43.

The number of the pins 43 may be four as shown, and the four pins 43 are disposed at four corners of the antenna assembly 4 and welded to the first antenna 41 and the second antenna 42, so as to ensure stability and reliability of connection between the first antenna 41 and the second antenna 42. Of course, the number of pins 43 may be one, two or more, as long as the communication between the first antenna 41 and the second antenna 42 is enabled and the stability of the connection between the two is ensured.
