[0040] In the present embodiment, a mounting cavity is provided on the side wall of the housing 1 on which the output interface 3 is installed, and the mounting cavity is used to install the elastic strip 10 and the sliding block 12. When the sliding blocks 12 at both ends move to the two sides of the mounting cavity respectively, the mounting block 13 will be lifted and the mounting block 13 will be inserted into the socket 401. As shown in the drawings of the specification, the sliding block 12 is a trapezoidal structure, and the input plug 4 is provided with a socket 401, and the socket 401 is used to cooperate with the limit block 5 to fix the relative position between the output connector and the input plug 4. The locking mechanism includes an elastic strip 10, a connecting spring 11, a sliding block 12, a mounting block 13 and a limit spring 14. The elastic strip 10 is made of PVC material, which has good flexibility and elasticity, can be bent and rebounded repeatedly, and is also inexpensive. The elastic strip 10 is symmetrically arranged on both sides of the output interface 3, and the sliding blocks 12 are symmetrical. Arranged on both sides of the elastic strip 10, the connecting spring 11 is a tension spring, and the connecting spring 11 is used to cooperate with the elastic strip 10 to drive the sliding block 12 and the elastic strip 10 to reset when unlocking. As shown in the figure of the specification, the two ends of the connecting spring 11 are respectively connected to different sliding blocks 12, and the elastic strip 10 is pressed by the input plug 4 to drive the sliding blocks 12 to move away from each other, and then the mounting block 13 is pushed out of the mounting cavity through the sliding block 12 and inserted into the socket 401. A part cavity 1301 is opened inside the mounting block 13, and the part cavity 1301 is used to install the pressing rod 15, the limit spring 14 and the limit block 5. The limit spring 14 is arranged in the part cavity 1301, and the limit block 5 is connected to the limit block 5. In this embodiment, the connecting spring 11 and the limit spring 14 are made of PET plastic, which will not affect the operation of the circuit while ensuring elasticity.

[0041] In this embodiment, the part cavity 1301 is symmetrically provided with a slide groove 1302, which is used to install the limit spring 14 and the limit block 5. The slide groove 1302 is also used to limit the movement direction of the limit block 5 so that the limit block 5 can only move along the slide groove 1302. The limit spring 14 and the limit block 5 are symmetrically arranged in the slide groove 1302.

[0042] In this embodiment, the unlocking mechanism includes a pressing rod 15 and a connecting rod 16. As shown in the accompanying drawings of the specification, one end of the pressing rod 15 is arranged on the outside of the part cavity 1301, and the pressing rod 15 is provided with a connecting groove 1501, and the connecting groove 1501 is used to install the connecting rod 16. There are two connecting rods 16. As shown in the accompanying drawings of the specification, the two connecting rods 16 are coaxially connected to the connecting groove 1501, and one end of the two connecting rods 16 away from the pressing rod 15 is respectively connected to different limit blocks 5. By pressing the pressing rod 15 into the part cavity 1301, the connecting rod 16 drives the limit block 5 to enter the part cavity 1301 for unlocking.

[0043] Working principle: When using, install the corresponding interface driver board according to the specific microwave module interface requirements. Then, according to the specific microwave module control protocol, write the corresponding control program and connect the matching control cable to complete the control requirements of the microwave module;

[0044] When the output interface 3 and the input plug 4 of the microwave module are connected to each other, when the input plug 4 is inserted, it will press against the elastic strip 10 and push the sliding block 12 to move in the installation cavity through the elastic strip 10. When the sliding block 12 moves, it will drive the installation block 13 to extend out of the installation cavity, and the installation block 13 will be inserted into the socket 401. When entering the socket 401, since the limit block 5 is a trapezoidal structure, the limit block 5 is first pressed by the input plug 4 and contracts. As the installation block 13 continues to move until the limit block 5 moves to the outside of the socket, the limit spring 14 will drive the limit block 5 to pop out and lock the output interface 3 and the input plug 4 of the microwave module.

[0045] When it is necessary to unlock the output interface 3 and the input plug 4 of the microwave module, it is only necessary to press the pressing rod 15, which will drive the connecting rod 16 to move and then drive the limit block 5 to retract into the part cavity 1301 (the limit spring 14 is compressed). At this time, since there is no restriction of the limit block 5, the connecting spring 11 will reset and drive the sliding blocks 12 to move closer to each other. When the sliding blocks 12 move closer to each other, the elastic strip 10 will bend and then separate the output interface 3 and the input plug 4 of the microwave module, so that the input plug 4 is ejected;

[0046] In the application of microwave modules that require pulse operation of power amplifiers, the required pulse signal is generated by the main control chip 2 and output to the synchronous test instrument through the BNC connector 7 to complete the required automatic test requirements.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
