Description

Technical Field

[0001] The invention relates to the technical field of drive circuit boards, in particular to a serial port screen drive circuit board with a shielding cover. Background Art

[0002] Serial port screen, an intelligent serial port controlled display screen that can be redeveloped in a configurable manner, refers to a TFT color LCD display control module with serial port communication. It can be connected to external devices such as PLC, frequency converter, temperature control instrument, data acquisition module, etc., and use the display screen to display relevant data. Parameters are written or operation instructions are input through input units such as touch screen, buttons, mouse, etc., so as to realize information interaction between users and machines. It is widely used in various display fields such as industrial automation, smart home appliances, transportation tracks, data rooms, charging piles, power medical, national defense security, shared equipment, etc. Among them, the driver circuit board in the serial port screen is an important component of electronic equipment for controlling and driving various electronic components. Its main functions include controlling the work of LED lamp beads, motors, LCD screens and other components.

[0003] In order to adapt to screens of various sizes and shapes, a serial port screen driver circuit board with a shielding cover is provided (see patent number: 202122762448.5 for details), including: a core substrate, serving as an installation platform and support carrier for the entire circuit board; a CPU, connected to the serial port screen, for driving the interface program of the serial port screen; a general memory, connected to the CPU, for storing the CPU's startup configuration file, user font file, and some user UI icons; a power conversion circuit, placed on the core substrate and connected to the CPU, for powering the entire circuit board; a shielding cover, for monitoring and reducing the interference of external electromagnetic waves on the entire circuit board. The serial port screen driver circuit board described in the present invention separates the core driver circuit part on the serial port screen and is designed into a small core driver circuit board, which changes the problem that the traditional serial port screen needs to match a relatively large PCB board and cannot integrate the serial port board driver into the customer's mainboard, and is easy to use.

[0004] However, the existing shielding cover is generally directly fixed on the serial port screen driver circuit board. If there is a problem with the components inside the shielding cover, it is difficult to remove it and perform maintenance operations on the components located there, thereby reducing the utilization rate. Summary of the invention

[0005] The purpose of the present invention is to provide a serial port screen driver circuit board with a shielding cover in order to solve the problem that the existing shielding cover is generally directly fixed on the serial port screen driver circuit board. If there is a problem with the components located inside the shielding cover, it is difficult to remove it and perform maintenance operations on the components located there, thereby reducing the utilization rate.

[0006] To achieve the above object, the present invention provides the following technical solution: a serial port screen driver circuit board with a shielding cover, comprising:

[0007] Circuit board, used to control and drive the various components of the serial port screen and ensure their normal operation;

[0008] A protection component is located on the top of the circuit board and is detachably connected to the circuit board;

[0009] Holes are provided on both sides of the top of the circuit board, and sockets are provided on both sides of the top of the circuit board and at the end faces of the holes. The holes and one end of the sockets are provided with continuous movable holes. The protective component includes a shielding cover, and first clamps matching the holes are provided at the middle positions on both sides of the bottom of the shielding cover, and second clamps matching the sockets are provided on both sides of one end of the bottom of the shielding cover.

[0010] As a further solution of the present invention: the hole and the movable hole as well as the plug hole and the movable hole are all L-shaped structures.

[0011] As a further solution of the present invention: the shielding cover is engaged and connected with the circuit board through the cooperation of the first clamping member, the hole, the second clamping member and the jack.

[0012] As a further solution of the present invention: the first clamping member and the second clamping member are both detachably connected to the hole and the socket respectively through the movable hole.

[0013] As a further solution of the present invention: a heat dissipation hole is provided on one side of the shielding cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the provided circuit board and protective assembly, when in use, the shielding cover is brought into contact with the circuit board, and the first clamp and the second clamp on the shielding cover are respectively extended to the bottom of the circuit board through the hole and the jack, and the first clamp and the second clamp are both staggered with the movable hole, and then the first clamp and the second clamp are bent by applying force using an external tool (pliers) to bend them into an L-shaped structure, so that they can be clamped on the circuit board. When the shielding cover needs to be removed, it is only necessary to apply force to push the shielding cover toward the position of the movable hole, so that the first clamp and the second clamp are moved to the position of the movable hole, so that a gap is created between the first clamp and the second clamp moved to the position of the movable hole and the movable hole, so that it is convenient to use pliers to pry the first clamp and the second clamp later, which provides convenience for the subsequent removal of the shielding cover, thereby improving the utilization rate.
