Detailed Description
The utility model will be described in detail with reference to the accompanying drawings and detailed description.
Example 1
The utility model provides a fixing structure of an RRU radio frequency module, which is shown in figures 1 to 3, and comprises a mounting plate 1, wherein a pair of side plates 2 are fixed on the mounting plate 1 in parallel at intervals to form a groove-shaped RRU radio frequency module mounting cavity. The inner wall in installation chamber articulates there is wedge joint piece 9, and the tip of joint piece 9 is articulated with installation chamber inner wall, and the free end of joint piece 9 is connected with the elastic component 10 that the other end is connected to installation chamber inner wall, and through-hole 7 has been seted up to the lateral wall in installation chamber correspondence joint piece 9, is provided with connecting rod 8 in the through-hole 7, and the one end of connecting rod 8 inwards extends to articulate to joint piece 9, and the other end of connecting rod 8 outwards extends to be connected with and draws button 6.
Example 2
The RRU radio frequency module comprises a cylindrical shell 3, and a clamping groove 11 matched and clamped with the wedge-shaped clamping block 9 is formed in the outer side wall of the shell 3. A fixing frame 4 is arranged in the shell 3, and an RRU radio frequency circuit board 5 is arranged on the fixing frame 4.
Example 3
