DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a high-frequency microwave printed circuit board includes a PTFE substrate 1, a conductor layer 2, a solder pad 3, a fixed block 4, a support column 5, a mounting member 6, a mounting hole 7, a sliding hole 8, a guide rail 9, and a fixed plate structure 10. The conductor layer 2 is fixed to the top of the PTFE substrate 1, the solder pad 3 is distributed on the conductor layer 2, the fixed block 4 is distributed on the front and rear parts of the left and right ends of the PTFE substrate 1, the front and rear ends of the support column 5 are respectively fixed to the inner ends of the left and right fixing blocks 4, the mounting member 6 is distributed on the support column 5, the mounting hole 7 is opened at the bottom of the mounting member 6, the sliding hole 8 is opened at the left and right parts of the mounting member 6, the guide rail 9 is distributed on the bottom of the PTFE substrate 1, and the fixed plate structure 10 is installed on the bottom of the PTFE substrate 1 through the guide rail 9.

[0015] The fixed plate structure 10 includes a limit plate 11, a positioning plate 12, a positioning hole 13, and a positioning column 14. The limit plate 11 is slidably connected to the guide rail 9 in the front and rear direction. The positioning plate 12 is fixed to the middle part of the bottom end of the limit plate 11. The positioning hole 13 is opened at the left and right ends of the positioning plate 12, and the positioning hole 13 corresponds to the sliding hole 8. The positioning column 14 is slidably connected to the positioning hole 13 through the sliding hole 8.

[0016] The fixing plate structure 10 is integrally fixed by the mounting member 6 .

[0017] The working principle of the utility model is as follows: the mounting part 6 is fixed to the equipment housing or bracket through the mounting hole 7 to fix the PTFE substrate 1 through the fixing block 4. When the accessories need to be replaced for plugging and unplugging, the positioning plate 12 is inserted into the bottom end of the PTFE substrate 1 along the slide rail 9 through the limit plate 11 to form a longitudinal support. The positioning column 14 is inserted into the positioning hole 13 through the slide hole 8 to connect all the positioning plates 12, so that the fixed plate structure 10 forms a whole, and the PTFE substrate 1 is fixed as a whole, and deformation caused by the plugging and unplugging of accessories will not cause line breakage.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
