Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to a circuit board with a shielding structure. Background Art

[0002] Circuit boards are important electronic components. They are the support for electronic components and the carrier for the electrical connection between electronic components. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as they have electronic components such as integrated circuits, must use circuit boards to make electrical interconnections between the various components.

[0003] During the use of existing circuit boards, any interference signal may affect the normal operation of the circuit boards, and the shielding structure installed on the circuit boards is not convenient to disassemble. When the circuit boards are damaged, the shielding structure is also abandoned, which reduces the use cost of the circuit boards. Therefore, a circuit board with a shielding structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a circuit board with a shielding structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a circuit board with a shielding structure, comprising a circuit board, wherein two clamping components are arranged on the circuit board, and the same shielding component is arranged in the two clamping components, and the shielding component is arranged on the circuit board.

[0006] As a preferred embodiment, the circuit board includes a main body, a circuit component is provided on the main body, the main body is connected to two clamping components, and the main body is overlapped with a shielding component.

[0007] As a preferred implementation, the snap-on assembly includes a fixing frame connected to the main body, a first rubber pad is connected inside the fixing frame, and both the fixing frame and the first rubber pad are overlapped with the shielding assembly.

[0008] As a preferred embodiment, the shielding assembly includes a shielding shell, two second rubber pads are connected to the shielding shell, the adjacent sides of the two second rubber pads are overlapped with the first rubber pad, and the shielding shell and the two second rubber pads are overlapped on the main body.

[0009] As a preferred implementation, the shape of the fixing frame is set to be L-shaped, and the shape of the shielding shell is set to be U-shaped.

[0010] As a preferred implementation, the front side of the first rubber pad is in a wedge shape, and the back side of the second rubber pad is in a wedge shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a clamping assembly, a shielding assembly and a circuit board, and the shielding assembly is moved, and the shielding assembly moves into two clamping assemblies, so that the shielding assembly can be quickly installed in a suitable position and then the working circuit board is shielded. At the same time, when the circuit board is damaged, it can be disassembled by only pulling the shielding assembly to remove it from above the circuit board, and then it can be installed on a new circuit board to reuse it, thereby reducing the use cost of the circuit board;

[0013] The utility model is provided with a first rubber pad and a second rubber pad. When the shielding shell drives the two second rubber pads to contact the two first rubber pads respectively, the inclined surface of the first rubber pad contacts the inclined surface of the second rubber pad. The two second rubber pads moving backwards can squeeze the two first rubber pads, so that the first rubber pad and the second rubber pad are deformed. The deformed first rubber pad and the second rubber pad can firmly fix the shielding shell between the two fixing frames. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with embodiments.

[0021] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] See also Figure 1-5 The utility model provides a circuit board with a shielding structure, including a circuit board 1, two clamping components 2 are arranged on the circuit board 1, the circuit board 1 includes a main body 11, a circuit component 12 is arranged on the main body 11, the main body 11 is connected with the two clamping components 2, the main body 11 is overlapped with the shielding component 3, the two clamping components 2 are provided with the same shielding component 3, the clamping component 2 includes a fixing frame 21, the fixing frame 21 is connected to the main body 11, a first rubber pad 22 is connected in the fixing frame 21, and a shielding shell 31 is arranged, and the shielding shell 31 can shield the components for signals;

[0023] The fixing frame 21 and the first rubber pad 22 are both overlapped with the shielding component 3. The shielding component 3 is arranged on the circuit board 1. The shielding component 3 includes a shielding shell 31. Two second rubber pads 32 are connected inside the shielding shell 31. The adjacent sides of the two second rubber pads 32 are overlapped with the first rubber pad 22. The shielding shell 31 and the two second rubber pads 32 are overlapped on the main body 11. By providing the first rubber pad 22 and the second rubber pad 32, the deformed first rubber pad 22 and the second rubber pad 32 can firmly fix the shielding shell 31 between the two fixing frames 21.

[0024] The shape of the fixing frame 21 is set to be L-shaped, and the shape of the shielding shell 31 is set to be U-shaped. By setting the fixing frame 21, since the shielding shell 31 is slidably connected in the two fixing frames 21, the two fixing frames 21 cooperate with each other to limit the shielding shell 31;

[0025] The front surface of the first rubber pad 22 is configured in a wedge shape, and the back surface of the second rubber pad 32 is configured in a wedge shape.

[0026] The working principle and use process of the utility model are as follows: the shielding shell 31 is pushed, and the shielding shell 31 moves into the two fixing frames 21. At the same time, the moving shielding shell 31 drives the two second rubber pads 32 to contact the two first rubber pads 22 respectively. The two second rubber pads 32 squeeze the two first rubber pads 22, and the first rubber pads 22 and the second rubber pads 32 are deformed. When the shielding shell 31 completely moves above the circuit component 12, the deformed first rubber pads 22 and the second rubber pads 32 fix the shielding shell 31 on the circuit board 1.
