[0030] Embodiment 1:

[0031] As Figures 1 to 3As shown, the embodiment provides a PXI switch module with installation reinforcing structure, including vertically fixed PCB board 1 and RF coaxial switch installation slot plate 2, and installation reinforcing structure is fixed on both sides of PCB board 1 and bottom near RF coaxial switch installation slot plate 2. RF coaxial switch installation slot plate is used for fixing RF coaxial switch.

[0032] PCB board 1 and RF coaxial switch installation slot plate 2 are fixed together through fixing block, and two vertical holes are opened in fixing block, one hole is used for fixing on PCB board 1, and the other hole is used for fixing RF coaxial switch installation slot plate 2.

[0033] Specifically, the installation reinforcing structure includes reinforcing side plate and reinforcing plate 3, and reinforcing plate 3 is fixed on bottom of PCB board 1 near RF coaxial switch installation slot plate 2, and both sides of the PCB board 1 are provided with clamping groove for fixing reinforcing side plate, and reinforcing side plate slides along guide rail groove of PXI case.

[0034] In order to reinforce the side edge of PCB board 1, each reinforcing side plate includes front side plate 41 and rear side plate 42 fixedly connected, and the width and length of front side plate 41 are smaller than those of rear side plate 42, so that front side plate 41 can be clamped in clamping groove, as shown in Figure 2 As shown, rear side plate 42 is fixed on back of PCB board 1, and screw hole of fixed rear side plate and PCB board penetrates PCB board. When reinforcing plate is fixed, rivet screw can be used to penetrate PCB board, reinforcing plate and rear side plate to stably reinforce PCB board. The two side edges of PCB board 1 are reinforced, and the guide rail groove of PXI case is contacted through reinforcing side plate, so that PXI module is inserted into PXI case.

[0035] As shown in Figure 3 Generally, the upper half of PCB board 1 near case slot is provided with circuit wiring, which is convenient for communication with back plate of PXI case, so that protective cover plate is arranged to shield, and the protective cover plate is fixed on reinforcing plate 3, so that reinforcing plate 3 is fixed on the lower half of PCB board 1 near RF coaxial switch installation slot plate 2, so that reinforcing plate 3 can increase the structural strength of the lower half of PCB board 1, and reinforcing side plate can increase the strength of both sides of PCB board 1, so that PCB board 1 is balancedly reinforced. In order to further increase the structural strength of PCB board 1, a plurality of stud mounting holes 5 for mounting screws can be arranged on reinforcing plate 3, and stud mounting holes 5 penetrate reinforcing plate 3 and PCB board 1 at both ends, so as to fix reinforcing plate 3 and PCB board 1 together, and rivet stud can be prearranged in stud mounting hole 5, and meanwhile, other structures can also be mounted and fixed through stud mounting hole 5 if needed.

[0036] In order to make the stress uniform, a plurality of stud mounting holes 5 can be divided into four groups and fixed on reinforcing plate 3 in rotational symmetry.

[0037] It is understood that in this embodiment, a reinforcing plate 3 is installed on the PCB board 1, and reinforcing side plates are installed on both sides of the PCB board 1. The reinforcing side plates and the reinforcing plate 3 are installed on the bottom and sides of the PCB board 1. In this embodiment, the fixing method can be bolt fixing or screw fixing, and the reinforcing ribs 6, the PCB board 1 and the reinforcing plate 3 are fixed together by bolts. Threaded posts for installing rivet screws are pre-set on the reinforcing plate 3, which can also play a reinforcing role.

[0038] Example 2

[0039] like Figures 3-6 As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 1, when a PXI module with reinforced side plates is directly placed into the guide rail slot of the PXI chassis, the chassis guide rail is made of plastic while the reinforced side plates are made of rigid material. This increases friction when the reinforced side plates, acting as guide rails, contact the guide rail slots, making them prone to damage. In this embodiment, the reinforcing ribs are fixed to the back of the PCB board 1, and the two sides of the PCB board 1 are used directly as guide rails. Because the PCB board 1 is covered with a layer of resin, friction is reduced when the PCB board 1, acting as a guide rail, directly contacts the guide rails.

[0040] Specifically, in this embodiment, the installation reinforcement structure includes a reinforcing rib 6 and a reinforcing plate 3. The reinforcing plate 3 is fixed to the bottom of the PCB board 1 near the RF coaxial switch mounting slot 2, and the reinforcing rib 6 is fixed to the back of the PCB board 1. The two sides of the PCB board 1 slide along the guide rail slots of the PXI chassis.

[0041] The long side of the reinforcing rib 6 is parallel to the direction in which the PCB board 1 is inserted into the PXI chassis, and the reinforcing rib 6 is fixed at a position close to both sides of the PCB board 1.

[0042] Similarly, a threaded post for mounting rivet screws is fixed on the reinforcing plate 3, and the threaded post passes through the PCB board 1 and the reinforcing plate 3 to fix it to the PCB board 1. In order to facilitate the removal of the entire PXI switch module and its mounting structure from the PXI chassis, a pull handle 7 is installed below the RF coaxial switch mounting slot plate 2.

[0043] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model 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 this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
