Description

Technical Field

[0001] The utility model relates to the technical field of PIX switch modules, and in particular to an installation structure for a square radio frequency coaxial switch and a PXI switch module. Background Art

[0002] The overall shape of the RF coaxial switch of the PXI switch module can be made into a cylindrical shape or a square shape. For the cylindrical RF coaxial switch, its input and output ports are in a straight line with the axis of the cylinder. In order to save installation space, the axis of the cylindrical RF coaxial switch is parallel to the insertion direction of the PXI switch module into the PXI chassis, that is, the cylindrical RF coaxial switch is vertically fixed on the RF coaxial switch mounting slot plate. When the square RF coaxial switch is installed in the same way (that is, the axis of the square RF coaxial switch is parallel to the insertion direction of the PXI switch module into the PXI chassis), the direction of the fixing hole at the bottom is parallel to the opening of the base, that is, when the RF coaxial switch of the PXI switch module uses a square RF coaxial switch, if the square RF coaxial switch is fixed on the RF coaxial switch mounting slot plate using the fixing hole provided by the square RF coaxial switch, it cannot be fixed. This is because the fixing hole is parallel to the RF coaxial switch mounting slot plate and the square RF coaxial switch cannot be fixed. Utility Model Content

[0026] The following will detail the present utility model by referring to the attached drawings and in conjunction with the embodiments:

[0027] Embodiment 1:

[0028] As Figures 1 to 2As shown in the figure, this embodiment provides an installation structure for a square radio frequency coaxial switch 2, including a fixed base 1, a first fixing member, and a second fixing member. The fixed base 1 is provided with a first mounting hole 4 parallel to the mounting seat 21 of the square radio frequency coaxial switch 2 and a second mounting hole 5 perpendicular to the fixing hole 3 of the square radio frequency coaxial switch 2. The first fixing member passes through the first mounting hole 4 and the fixing hole 3 on the mounting seat 21 to fix the square radio frequency coaxial switch 2 to the fixed base 1. The second fixing member is used to fix the fixed base 1 on the radio frequency coaxial switch mounting slot plate 6 of the PXI module through the second mounting hole 5. And the first mounting hole 4 and the second mounting hole 5 are staggeredly installed. The second mounting hole 5 is opened along the insertion direction of the PXI module.

[0029] It can be seen that the opening directions of the first mounting hole 4 and the fixing hole 3 are on the same straight line. During installation, the first fixing member passes through the first mounting hole 4 and the fixing hole 3 to fix the square radio frequency coaxial switch 2 to the fixed base 1.

[0030] As Figure 2 shown in the figure, each fixed base 1 includes a first fixing block 11 and a second fixing block 12. The first fixing block 11 and the second fixing block 12 are both provided with a first mounting hole 4 and a second mounting hole 5. Each first mounting hole 4 corresponds to a fixing hole 3, and the four first mounting holes 4 are parallel, and the two second mounting holes 5 are arranged in parallel.

[0031] Specifically, both the first fixing member and the second fixing member are fixed by cooperating with screws and nuts. The first mounting hole 4 and the fixing hole 3 are provided with threads in the same direction, and the threads match the screws. After the screws pass through the first mounting hole 4 and the fixing hole 3 in sequence, they are fixed by nuts.

[0032] Embodiment 2

[0033] As Figures 3 - 5 shown in the figure, this embodiment provides a PXI switch module for a square radio frequency coaxial switch 2, including a radio frequency coaxial switch mounting slot plate 6 and a PCB board 8 perpendicular to the radio frequency coaxial switch mounting slot plate 6. The length direction of the PCB board 8 is the insertion direction of the PXI switch module into the PXI chassis. The mounting surface of the radio frequency coaxial switch mounting slot plate 6 is perpendicular to the length direction of the PCB board 8. The square radio frequency coaxial switch 2 is fixedly installed on the radio frequency coaxial switch mounting slot plate 6 through the installation structure of Embodiment 1. The radio frequency coaxial switch mounting slot plate 6 is provided with a fixed mounting hole 7 adapted to the second mounting hole 5. The second fixing member passes through the second mounting hole 5 and the fixed mounting hole 7 to fix the fixed base 1 on the radio frequency coaxial switch mounting slot plate 6. The opening directions of the second mounting hole 5 and the fixed mounting hole 7 are on the same straight line.

[0034] Specifically, as Figure 4As shown, in order to prevent the second fixing member from affecting the installation of the input and output ports of the square radio frequency coaxial switch 2 and for better aesthetics, the fixing mounting hole 7 is a counterbore. Correspondingly, the counterbore and the second mounting hole 5 are provided with threads in the same direction for fixing the screw. Similarly, the second fixing member is fixed by cooperating a screw with a nut. Since the fixing mounting hole 7 is a counterbore, the screw used is a cross recessed countersunk head screw, half countersunk head screw, countersunk head self-tapping screw, half countersunk head self-tapping screw, hexagon socket head cap screw or hexagon socket button head cap screw adapted to the counterbore, etc.

[0035] It can be understood that in this application, the square radio frequency coaxial switch 2 is a radio frequency coaxial switch such as SPDT-RADIALL, presenting an overall square structure. The mounting base 21 is also square, and the opening direction of the fixing hole 3 in the mounting base 21 is set perpendicular to the height direction of the mounting base 21. Generally, the square radio frequency coaxial switch 2 is fixed directly in other required modules through the fixing hole 3 on its mounting base 21. However, in order to miniaturize the PX switch module, it is required that the installation direction of the square radio frequency coaxial switch 2 be set along the insertion direction of the PXI switch module. However, to fix the radio frequency coaxial switch on the radio frequency coaxial switch mounting groove plate 6, since the opening direction of the fixing hole 3 is perpendicular to the insertion direction of the PXI switch module, either the opening direction of the fixing hole 3 of the mounting base 21 needs to be changed, but this will increase the area of the mounting base 21. If the PXI switch module wants to install the same number of square radio frequency coaxial switches, a larger area is required, which is not conducive to the miniaturized design of the PXI module.

[0036] Therefore, in this application, by setting a unilateral fixing base 1 and without changing the opening direction of the fixing hole 3, the square radio frequency coaxial switch 2 is first fixed on the fixing base 1, and then the fixing base 1 is fixed on the radio frequency coaxial switch mounting groove plate 6 of the PXI switch module to realize the fixation of the square radio frequency coaxial switch 2. At the same time, the installation area of the square radio frequency coaxial switch 2 is reduced, which is conducive to the miniaturized design of the PXI switch module.

[0037] It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present utility model, but the present utility model is not limited thereto. For those of ordinary skill in the art, various deformations and improvements can be made without departing from the spirit and essence of the present utility model, and these deformations and improvements are also regarded as the protection scope of the present utility model.
