[0029] After actual investigation and research, it was found that the multi-channel SMP plug-in devices currently available on the market are not satisfactory when multi-channel plug-in operations are performed on larger PCB boards. Without auxiliary tooling, it is easy for each SMP plug to be unevenly stressed, making it difficult to complete plug-in and pull-out, and even damaging the PCB and SMP plug. In view of this, the present application provides a multi-channel SMP plug-in device to improve plug-in efficiency, reduce operation difficulty, protect connectors, and meet the evolving technical needs.

[0030] The embodiments of the present application are explained below with reference to the accompanying drawings.

[0031] See also Figure 1 and Figure 2 As shown, this embodiment provides a multi-channel SMP plug-in device, including:

[0034] The plug-in assembly 3 is arranged on the mounting plate 1, and the PCB board 4 is arranged on the plug-in assembly 3 through the fixed pressure block 5. The plug-in assembly 3 is used to control the up and down movement of the PCB board 4 to enable the synchronous plugging and unplugging of the SMP interface between the PCB board 4 and multiple microwave components 2.

[0035] Specifically, in this embodiment, a plurality of discrete microwave components 2 are arranged at intervals on the mounting plate 1, with the aid of a plug-in component 3 provided on the mounting plate 1, wherein a PCB board 4 is provided below the plug-in component 3 through a fixed pressure block 5, and the movement of the plug-in component 3 is controlled to realize the up and down movement of the PCB board 4, thereby realizing the synchronous docking and plugging of the PCB board 4 and the multi-channel SMP of the plurality of discrete microwave components 2.

[0036] It should be noted that when the microwave component 2 is fixedly installed on the mounting plate 1, at least two of the several mounting holes provided on the microwave component 2 are used as positioning holes for pre-positioning. Therefore, when installing the microwave component 2, the positioning pins and fastening screws are used to achieve fixed installation between the mounting plate 1 and the microwave component 2.

[0040] Specifically, in this embodiment, a structure formed by the cooperation of fixed legs 31, linear guide rails 32, a control mechanism 33 and a beam arm 34 is designed. The four fixed legs 31 and a fixed plate 35 arranged at the top of the fixed legs 31 provide a support platform for the entire assembly, and a linear guide rail 32 is arranged on the side walls of the four fixed legs 31 to provide guidance for the up and down lifting of the beam arm 34. The control mechanism 33 is arranged on the fixed plate 35, and the telescopic end of the control mechanism 33 is connected to the top of the beam arm 34. By controlling the control mechanism 33, the beam arm 34 is moved along the linear guide rail 32, thereby realizing the up and down lifting of the PCB board 4.

[0041] It should be noted that, in order to save production costs, the control mechanism 33 in this embodiment adopts manual control, that is, a hand wheel, a ball screw and a bearing are used. In addition, an electric control method can also be used, which is bound to increase the cost investment. Therefore, no further details will be given here.

[0042] In some embodiments, Figure 3 and Figure 4 As shown, the edge of the beam arm 34 is provided with extensions 36 corresponding to the number of the microwave components 2, and the extensions 36 cooperate with the beam arm 34 to form an accommodation space, and the PCB board 4 is arranged in the accommodation space through the fixed pressing block 5;

In addition, since the microwave component 2 is equipped with an SMP-KK connector 22, in order to avoid the SMP-KK connector 22, a notch is provided on the fixed pressing block 5 to achieve the docking of the PCB board with the SMP interface of the microwave component 2.

[0047] In some embodiments, Figure 3 As shown, the upper end surface of the microwave component 2 is provided with a plurality of fixing protrusions 23, and the PCB board 4 is provided with through holes corresponding to the fixing protrusions 23, and the PCB board 4 is fixed on the fixing protrusions 23 by fastening screws;

Then, when the PCB board 4 is moved onto the fixing protrusions 23, the PCB board 4 is fixed to the microwave component 2 by tightening screws; at the same time, with the help of the positioning protrusions 24 (with inner holes provided in the positioning protrusions 24) provided on the microwave component 2, the positioning pin 6 penetrates the PCB board 4 and the beam arm 34 and is inserted into the positioning pin 6, so as to ensure the positioning accuracy during disassembly and assembly, and improve the plugging and unplugging efficiency.

[0050] The device works as follows:

[0051] 1. The specific insertion process is as follows:

[0052] First, each microwave component 2 is positioned and installed with the mounting plate 1 by means of positioning pins and fastening screws, then the SMP-KK connector 22 is installed in the SMP socket 21 of each microwave component 2, the beam arm 34 is moved to the upper position by means of a hand wheel, the PCB board 4 is fixed to the beam arm 34 by means of two positioning pins 6 and four PCB fixing blocks 5 with screws, and then the beam arm 34 is positioned as a whole with the positioning protrusion 24 of the microwave component 2 below by means of two positioning pins 6. After positioning, the four mounting legs are installed on the mounting plate 1 by means of four screws.

[0053] Finally, the PCB board 4 can be slowly moved downward as a whole along the positioning pin 6 by rotating the hand wheel to ensure that the eight SMP plugs 41 move downward synchronously, and finally complete the docking assembly of the PCB board 4 and the SMP plug 41 of the microwave component 2. After completion, remove the plug-in device, and then mechanically fix the PCB board 4 to the mounting threaded hole reserved on the top of the microwave component 2 by tightening screws to complete the final overall assembly.

[0054] 2. The specific removal process is as follows:

[0055] First, all the fixing screws on the PCB board 4 need to be removed, and then the plug-in component 3 is installed on the mounting plate 1 by four screws. During the process, two positioning pins 6 can be used for positioning. After the plug-in component 3 is installed, the positioning pins 6 are removed; then, the upper and lower positions of the beam arm 34 are adjusted to fit the PCB board 4 through the lifter, and the PCB board 4 is fixed to the beam arm 34 of the plug-in component 3 through four PCB board 4 fixing blocks 5 and screws. Finally, the hand wheel is manually rotated to slowly raise the beam arm 34 to achieve overall and uniform lifting of the PCB board 4. All SMP plugs 41 on the PCB board 4 are separated from the SMP-KK connector 22, and the removal of the multi-channel SMP is completed. After completion, the PCB board 4 can be removed from the plug-in device.
