Embodiment 1

[0023] Such as figure 1 , figure 2 , image 3 As shown, the size-adjustable PCB board holder includes a frame frame 1 and a PCB board 2 clamped in the frame frame 1; a groove 3 is opened on the inner wall of the frame frame 1, and the PCB board 2 The two ends are arranged in the grooves 3 on the left and right side walls of the frame 1 respectively; And the sliding rods 7 connected with the fixed rods 5 through springs 6 respectively;

[0024] In this embodiment, the sliding rod 7 is slidingly arranged in the casing 4. When the PCB board 2 is placed in the frame 1, the sliding rod 7 will be pressed by the PCB board 2 to move to the left and right ends until the PCB board 2 It is completely clamped in the groove 3 of the frame 1. In this solution, the frame 1 is adjustable so that the holder can be applied to PCB boards 2 of different sizes. The setting of the spring 6 is used to stretch the sliding rod 7 to prevent the sliding rod 7 from slipping out of the casing 4 . T...

Embodiment 2

[0026] In this embodiment, on the basis of Embodiment 1, the winding post 8 includes a support rod 9 and a snap ring 10 fixed on the upper end of the support rod 9 . The snap ring 10 includes a lower snap ring 11 and an upper snap ring 12 with one end hinged to the lower snap ring 11 and the other end snapped to the lower snap ring 11 . The lower snap ring 11 is fixed on the upper end of the support rod 9 .

[0027] In this embodiment, when the lines are to be collected, the upper snap ring 12 that is engaged with the lower snap ring 11 is opened, and the lines on the PCB 2 are placed in the snap ring 10 for fixing, so that the lines move toward the device in an orderly manner. Arranging in a certain direction not only makes the lines on the PCB 2 neat and beautiful, but also facilitates the heat dissipation of the PCB 2.

Embodiment 3

[0029] In this embodiment, on the basis of Embodiment 1 or Embodiment 2, one end of the frame 1 is open, and further includes extensions 13 respectively arranged on both sides of the opening, and threaded holes 14 are provided at the ends of the extensions 13 .

[0030] In this embodiment, the threaded hole 14 provided at the end of the extension section 13 is used to fix the entire frame 1 on the chassis.

Abstract

The invention discloses a size-adjustable PCB clamp. The size-adjustable PCB clamp comprises a frame and a PCB clamped in the frame. Grooves are formed in the inner side walls of the frame, and the two ends of the PCB are arranged in the grooves in the left and right side walls of the frame respectively. The frame comprises a sleeve, a fixed rod and sliding rods, wherein the sleeve is provided with openings in the two sides and is of a cavity structure, the fixed rod is arranged in an inner cavity of the sleeve, and the sliding rods are connected with the fixed rod through springs. A wrapping post is arranged on the frame. According to the size-adjustable PCB clamp, because the sliding rods are arranged in the sleeve in a sliding mode, the clamp can be adjusted and applied to PCBs of different sizes; the springs are arranged and used for pulling the sliding rods and preventing the sliding rods from sliding out of the sleeve; the wrapping post arranged on the PCB is used for collecting wires scattered on the PCB and guaranteeing that heat dissipation of the PCB is not affected.

Description

technical field [0001] The invention relates to a clamper, in particular to a size-adjustable PCB board clamper. Background technique [0002] The printed circuit board is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because of its powerful functions, it is now widely used. In the assembly process of the existing PCB circuit board, the PCB circuit board is generally fixed on the casing by means of screw fixing, that is, the PCB circuit board is generally provided with mounting holes, and the screws are embedded in the corresponding mounting holes and screwed on during assembly. Installed in the case. However, in actual use, the PCB circuit board fixed by screws is easy to be damaged due to vibration and other reasons. In order to solve this defect, a clamper is mostly used to clamp the PCB board, and then the clamper is fixed on the chassis. However, since the PCB board has vari...
