[0038] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0039] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0040] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0041] See Figures 1 to 3The embodiment of the present invention provides a circuit board vertical support structure, comprising: a chassis shell 10, a main circuit board 20, a vertical circuit board 30 and a limit block 40, wherein the main circuit board 20 is installed in the chassis shell 10; one end of the vertical circuit board 30 is plugged into the main circuit board 20 and is vertically arranged between the main circuit board; the limit block 40 is installed on the chassis shell 10 and clamps the other end of the vertical circuit board 30. Figure 1 As shown in , the main circuit board 20 can be installed and fixed in the chassis shell 10 by screws or other means. Since one end of the vertical circuit board 30 is plugged into the main circuit board 20 and is arranged perpendicular to the main circuit board, a limit block 40 is set above the vertical circuit board 30. In conjunction with the plug-in connection method below the vertical circuit board 30, the two ends of the vertical circuit board 30 can be relatively fixed, so that the vertical circuit board 30 cannot move forward and backward, up and down, or rotate. It is restricted by the limit block 40 and does not tilt left and right. This solves the problem in the prior art that the vertical circuit board 30 tilts when it is fixed only by plug-ins, resulting in poor fit of the switch panel and instability of the vertical circuit board 30 during the drop test.
[0042] See Figures 1 to 3 , a clamping groove 401 is provided on the limiting block 40, and the other end of the vertical circuit board 30 is arranged in the clamping groove 401 so as to be clamped and fixed by the clamping groove 401. A limiting groove 301 is provided at the opposite position of the vertical circuit board 30 and the clamping groove 401, and the vertical circuit board 30 is arranged in the clamping groove 401 through the limiting groove 301. The width a of the cross section of the clamping groove 401 is adapted to the thickness of the vertical circuit board 30. The length b of the cross section of the clamping groove 401 is adapted to the length of the limiting groove 301. The limiting block 40 is in the shape of an irregular ear plate. Since the distance between the ear plates is slightly larger than the thickness of the vertical circuit board 30 or at least equal to the thickness of the vertical circuit board 30, the limiting block 40 can clamp the vertical circuit board 30 tightly through the clamping groove 401 to prevent the vertical circuit board 30 from tilting. In addition, since the length b of the cross section of the clamping groove 401 is adapted to the length of the limiting groove 301, the clamping groove 401 is completely adapted to the limiting groove 301, so that the limiting block 40 completely clamps and fixes the vertical circuit board 30 in the left, right, front and back directions, making it less likely that the vertical circuit board 30 will become unstable during a drop test.
[0043] See Figure 1 and Figure 3The circuit board vertical support structure further comprises a fixing screw 50, one side of the limiting block 40 is provided with a mounting hole 402, the cabinet shell 10 is provided with a fixing hole 1011, and the fixing screw 50 is in threaded connection with the mounting hole 402 on the limiting block 40 in a penetrating mode of the fixing hole 1011, so that the limiting block 40 is mounted and fixed into the cabinet shell 10. The limiting block 40 is provided with an M3 screw hole, and the limiting block 40 is mounted on the switch side wall through the fixing screw 50. During installation, the vertical circuit board 30 can be first connected to the main circuit board 20 through SMT plug-in, then the main circuit board 20 and the vertical circuit board 30 are loaded into the switch shell, at this time, the vertical circuit board 30 is not supported in the left-right direction, and the vertical circuit board 30 is inserted into the limiting block 40, at this time, the vertical circuit board 30 is limited by the limiting block 40, the switch side wall and the limiting block 40 are tightened through the fixing screw 50, at this time, the limiting block 40 is fixed in the switch shell and limits the vertical circuit board 30. The ear plate of the limiting block 40 is inserted into the limiting groove 301 of the vertical circuit board 30, so that the vertical circuit board 30 can be locked and fixed. The main circuit board 20 and the bottom plate of the cabinet shell 10 are fixedly connected; and the limiting block 40 and the side plate of the cabinet shell 10 are fixedly connected.
[0044] When the switch needs to be disassembled, the fixing screw 50 of the switch side edge is disassembled by using an electric screwdriver, the limiting block 40 is removed, and then the vertical circuit board 30 and the main circuit board 20 can be taken out. The disassembly and assembly are convenient, fast, time-saving and labor-saving.
[0045] Referring to Figure 2 and Figure 3 The circuit board vertical support structure further comprises a connector 60, and the one end of the vertical circuit board 30 is inserted on the main circuit board 20 in a plug-in mode of the connector 60. In an embodiment of the utility model, the connector 60 is an STM plug-in connector 60. After the vertical circuit board 30 with the mounting hole 402 is fixed on the main circuit board 20 in a plug-in mode, the vertical circuit board 30 is fixed to the side edge of the switch shell through the limiting structure of the limiting groove 301, and is inserted in a plug-in mode of the STM plug-in connector 60, so that installation and disassembly are facilitated.
[0046] The circuit board vertical support structure provided by the embodiment of the utility model, through the increase of vertical circuit board 30 limiting block 40 and positioning screw, limiting block 40 is fixed on the switch box through screw, vertical circuit board 30 is limited in limiting block 40, the position of vertical circuit board 30 in the switch is fixed, perpendicular to main circuit board 20. Because vertical circuit board 30 is limited by space condition in the switch, the method of fixing vertical circuit board 30 by conventional inside screw is not conducive to the disassembly of PCB circuit board with electric screwdriver. When vertical circuit board 30 is only fixed by plug-in, there will be the situation of left and right inclination of vertical circuit board 30. Therefore, the limiting structure of vertical circuit board 30 is increased, and the screw and limiting block 40 are directly installed on the side of the switch with the electric screwdriver, so that the perpendicularity of the PCB board can be maintained when the vertical circuit board 30 is assembled in the switch. When the switch needs to be disassembled, the side screw of the switch is disassembled with the electric screwdriver, the limiting block 40 is removed, and then the vertical circuit board 30 can be taken out. The disassembly is convenient and fast, time and labor are saved, and the conventional electric screwdriver can meet the requirements.
