[0030] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0031] Embodiment 1:

[0032] like Figures 1 to 7As shown, this embodiment provides a protective PXI switch module installation structure, wherein the PXI switch module includes a plurality of RF coaxial switches 5, a first PCB board 6 and a second PCB board 7, the installation structure includes a back plate 1 and a slot plate 2 that are vertically fixedly connected, the first PCB board 6 is fixedly installed at the bottom of the back plate 1, a plurality of RF coaxial switches 5 are fixedly installed above the slot plate 2 parallel to the back plate 1 and located in front of the first PCB board 6, the second PCB board 7 is fixed at the top of the first PCB board 6, and a PCB cover 3 is provided on the first PCB board 6. Studs 8 are provided between the two ends of the bottom of the second PCB board 7 and the first PCB board 6, one end of the stud 8 is threadedly connected and fixed to the second PCB board 7, and the other end is threadedly connected to the first PCB board 6. Threaded holes are provided on both sides of the first PCB board 6, and the first PCB board 65 is bolted to the back plate 11. After all PXI switch modules are fixed to the installation structure, the entire structure is installed on the back plate 11 of the PXI chassis.

[0033] Specifically, Figure 2-Figure 3 As shown, the PCB cover 3 includes a protective plate 31, baffles 32 are arranged around the protective plate 31, and clamping plates 33 are arranged at the connection between adjacent baffles 32. The PCB cover 3 is fixed to the four corners of the first PCB board 6 through the clamping plates 33. Figure 5 As shown, the clamping plate 33 and the adjacent baffle plate 32 may form a clamping groove, which is clamped on the four corners of the first PCB board 6, and then the PCB cover 3 is fixed to the four corners of the first PCB board 6 through the first fixing holes 34 and the second fixing holes 35.

[0034] The clamping plate 33 is an L-shaped plate, and a chamfer is provided at the right angle of the L-shaped plate. The adjacent two sides of the clamping plate 33 abut against the connection between the two adjacent baffles 32, and can be made in one piece. A first fixing hole 34 is provided on the clamping plate 33, and a second fixing hole 35 matching the first fixing hole 34 is provided at a position corresponding to the first fixing hole 34 on the protective plate 31. In this way, the clamping plate 33, the baffle 32 and the protective plate 31 can form a U-shaped groove, which can be buckled at the four right angles of the PCB board.

[0035] like Figure 4 As shown, in order to connect the PCB board to the RF coaxial switch 5, a first opening 36 for wiring to pass through is provided on the protection plate 31 and the baffle plate 32, corresponding to the position of the wiring port of the first PCB board 6. A second opening 37 for the spare wiring to pass through is provided on the protection plate 31 and the baffle plate 32, corresponding to the position of the spare wiring port of the first PCB board 6.

[0036] In order to more clearly identify the model, name or manufacturer of the current PXI switch module, the protection plate 31 may be provided with an identification groove for identifying the name of the PXI switch module by printing or imprinting.

[0037] Specifically, in this embodiment, the back plate 1 and the slot plate 2 are connected vertically by the fixing member 4, wherein Figure 6 As shown, the fixing member 4 includes an integrally formed first mounting block 41 and a second mounting block 42, the first mounting block 41 is fixed to the bottom end of the back plate 1, and the second mounting block is fixed to the end of the slot plate 2. The first mounting block 41 is provided with a threaded hole perpendicular to the plane of the back plate 1, and the first fixing block is fixed to the back plate 1 by bolts, and the second mounting block 42 is provided with a screw hole perpendicular to the slot plate 2 and parallel to the back plate 1, and the second mounting block 42 is fixed to the slot plate 2 by bolts. Since the first mounting block 41 and the second mounting block 42 are integrally formed, the back plate 1 and the slot plate 2 are vertically fixedly connected together. In order to reduce the size of the fixing member 4, the first mounting block 41 and the second mounting block 42 are connected in a Z shape, so that the yield structure formed by the first mounting block 41 and the second mounting block 42 can be just clamped on the square flange of the RF coaxial switch at the end of the slot plate 2.

[0038] In this embodiment, the RF coaxial switch 5 includes a housing 51, and the circuit and components of the RF coaxial switch are installed inside the housing 51. The housing 51 is plugged into the first PCB board 6. The housing 51 is provided with a first port 54 and a second port at both ends. The first port 54 passes through the slot plate 2 and is located below the slot plate 2. The housing 51 is fixedly installed above the slot plate 2, and the second port is connected to the second PCB board 7. A square flange seat 52 is provided between the housing 51 and the slot plate 2. The housing 51 and the flange seat 52 are integrally formed. Mounting bolts are provided at the four corners of the flange seat 52 to fix the housing 51 above the slot plate 2. Optionally, the housing 51 is a cylindrical structure. The axis of the RF coaxial switch 5 is installed parallel to the length direction of the first backplane 1. The slot plate 2 is provided with a through hole slot with the RF coaxial switch 5. The size of the through hole slot is smaller than the flange seat 52, so that the end of the RF coaxial switch 5 can pass through the through hole slot and then be fixed to the slot plate 2 through the flange seat 52.

[0039] In order to avoid the connector 53 used in the second port being too large, which will cause the overall structure to become larger, in the present application, the second port is connected to the second PCB board 7 through the J30J-9ZJ connector 53. In addition, a number of RF coaxial switches are closely arranged and installed along the length direction of the slot board 2. In order to facilitate the entire PXI switch module and its installation structure to be pulled out from the PXI chassis, a pull handle 9 is installed under the slot board 2.

[0040] The focus of this application is on how to install, fix and integrate the various components of the PXI switch module together to make the entire structure compact. The specific circuit composition and working principle of each part of the PXI switch module (such as the RF coaxial switch) use existing technologies. It should be noted that a functional circuit for completing PCI to FPGA communication is arranged on the first PCB board 6, and a functional circuit is arranged on the second PCB board 7. The function of the functional circuit is to output high and low levels under the control of the first PCB board 6 to control the RF coaxial switch. The functional circuit on the first PCB board and the functional circuit on the second PCB are both existing commonly used circuits and will not be described in detail in this article.

[0041] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
