Description

A high-frequency filtering module for PCB control board Technical Field

[0001] This utility model belongs to the field of PCB boards, and in particular relates to a high-frequency filtering module for a PCB control board. Background Technology

[0002] With the continuous development of technology, electronic products are increasingly being used in people's production and daily life. PCB control boards are needed in the manufacturing of electronic products. During the operation of the PCB control board, high-frequency interference signals can seriously affect the normal operation of the circuit, leading to signal distortion, unstable equipment operation, and other problems. The high-frequency filtering module of the PCB control board can shield interference signals to ensure normal signal transmission. However, existing high-frequency filtering modules of PCB control boards are easily damaged by collisions with the PCB board during use, which can affect the quality of the product. Summary of the Invention

[0003] The purpose of this invention is to provide a high-frequency filtering module for a PCB control board to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-frequency filtering module for a PCB control board includes a PCB board, an arc-shaped base, a filtering module housing, and support rods. The PCB board has a cuboid design, with arc-shaped bases for screw mounting on both sides. The arc-shaped bases are mounted on the substrate by screws, and grooves are formed in the arc-shaped bases. The filtering module housing is mounted on one side of the top of the PCB board, and a support rod for screw mounting is provided on the arc-shaped base. The support rod has a diagonal brace design, and the other end of the support rod is connected to the bottom of the PCB board. The two support rods are symmetrically arranged along the center line of the PCB board.

[0006] Preferably, the PCB board has mounting holes that penetrate the PCB board. There are three mounting holes arranged in a triangle on the PCB board. The bottom of the filter module housing has pins that connect to the mounting holes. The pins and mounting holes are arranged in a one-to-one correspondence. The pins are electrically connected to the electrical components inside the filter module housing.

[0007] Preferably, the pin includes a post, an upper disk, a lower disk, and a spring. The upper disk is installed at the bottom of the filter module housing and is electrically connected to the electrical components inside the filter module housing. The upper disk has a screw-mounted post connected to a mounting hole, and the length of the post is greater than the depth of the mounting hole. A spring is sleeved below the post, and the top of the spring contacts the bottom of the PCB board. The bottom of the post has a screw-mounted lower disk. Both the lower disk and the spring are located below the PCB board. The upper disk and the post are made of conductive material, and the spring is in a compressed state after installation.

[0008] Preferably, the support rod has an installation groove, in which a reinforcing rod can be installed.

[0009] Compared with the prior art, this utility model has the following advantages: The utility model is reasonably designed; the PCB board is mounted on the substrate through the arc-shaped seat. When the product is impacted, the arc-shaped seat can buffer and protect the PCB board. The groove on the arc-shaped seat can deform under the pressure, thereby protecting the PCB board and the filter module housing. The design of the support rod reduces the deformation of the PCB board due to long-term suspension. The mounting groove reduces the weight of the support rod. If the PCB board and the filter module housing are heavy, a reinforcing rod can be installed to improve the strength of the support rod. The design of the mounting hole and pins facilitates the quick installation of the filter module housing. The spring and lower disc on the pin can generate a downward force to make the filter module housing and the PCB board tightly connected. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] As shown in Figures 1-4, a high-frequency filtering module for a PCB control board includes a PCB board 1, an arc-shaped base 2, a filtering module housing 4, and support rods 5. The PCB board 1 has a cuboid design. Arc-shaped bases 2, which are screw-mounted on both sides of the PCB board 1, are mounted on the substrate by screws. The arc-shaped bases 2 have grooves 3. The filtering module housing 4 is mounted on one side of the top of the PCB board 1. Support rods 5, which are screw-mounted on the arc-shaped bases 2, are of a diagonal brace design. The other end of the support rod 5 is connected to the bottom of the PCB board 1. Two support rods 5 are symmetrically arranged along the centerline of the PCB board 1. Mounting holes 6 are provided on the PCB board 1, penetrating the PCB board 1. There are three mounting holes 6 arranged in a triangle on the PCB board 1. The bottom of the filtering module housing 4 has pins 7, which connect to the mounting holes. 6. The pins 7 and mounting holes 6 are set one-to-one. The pins 7 are electrically connected to the electrical components inside the filter module housing 4. The pins 7 include the post 9, the upper disc 10, the lower disc 12, and the spring 11. The upper disc 10 is installed at the bottom of the filter module housing 4 and is electrically connected to the electrical components inside the filter module housing 4. The upper disc 10 is provided with a screw-mounted post 9. The post 9 is connected to the mounting hole 6, and the length of the post 9 is greater than the depth of the mounting hole 6. The spring 11 is sleeved under the post 9. The top of the spring 11 contacts the bottom of the PCB board 1. The lower disc 12 is provided at the bottom of the post 9. The lower disc 12 and the spring 11 are both located below the PCB board 1. The upper disc 10 and the post 9 are made of conductive material. After installation, the spring is in a compressed state. The support rod 5 is provided with a mounting groove 8, and the mounting groove 8 can be used to install the reinforcing rod.

[0016] The working principle of this utility model is as follows: First, the PCB board is installed in a suitable position using an arc-shaped base. Then, the support rod is installed as needed. If the arc-shaped base and the filter module housing are heavy, a reinforcing rod can be added in the mounting groove of the support rod. After the PCB board is installed, the pins at the bottom of the filter module housing are connected to the mounting holes. The uprights on the pins extend downwards through the mounting holes to the bottom of the PCB board. Then, the spring is fitted onto the uprights, and the lower disc is connected to the uprights, so that the spring is in a compressed state and the top of the spring is in contact with the bottom of the PCB board. The current on the PCB board enters the electrical components inside the filter module housing through the uprights and the upper disc. The electrical components inside the filter module housing filter the current and then transmit the electrical energy through the wires.
