Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit boards, in particular to an embedded PCB circuit board. Background Art

[0002] A PCB is an electronic component, also known as a printed circuit board or printed circuit board. It supports electronic components and serves as the electrical connection mechanism for these components. PCBs are manufactured using electronic printing, hence the name "printed" circuit board.

[0003] There are many types of PCBs, including but not limited to ceramic PCBs, alumina ceramic PCBs, aluminum nitride ceramic PCBs, aluminum substrates, high-frequency PCBs, thick copper PCBs, impedance PCBs, and ultra-thin PCBs. These different types of PCBs play unique roles in electronic devices. For example, flexible printed circuits (FPCs) offer high reliability, excellent flexibility, high wiring density, light weight, thinness, and good bendability. Rigid-flex PCBs, on the other hand, combine the characteristics of flexible and rigid PCBs through lamination and other processes.

[0004] Nowadays, most PCB circuit boards are installed on the housing or board using bolts. This requires manual alignment of the mounting holes on the PCB circuit board with the holes on the mounting board. Otherwise, accurate fixed installation cannot be completed. In this case, the installation operation requires the assistance of multiple people, which is quite troublesome.

[0005] Therefore, it is necessary to design an embedded PCB circuit board to solve the above-mentioned problems. Utility Model Content

[0012] As a preferred solution of the present invention, the diagonal positions of the heat-conducting net and the heat-conducting plate are fastened and fixed with slotted screws, and both the heat-conducting plate and the heat-conducting net are made of heat-conducting material.

[0013] As a preferred solution of the present invention, the heat dissipation mounting cover is fixedly connected to the heat conducting plate by screws and is located outside the heat conducting net. The heat dissipation mesh holes are a plurality of circular holes, and a dustproof net is laid inside.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In the present invention, an embedded PCB circuit board is provided. When the PCB circuit board is installed, the PCB circuit board body is embedded and installed inside the mounting plate body by utilizing the snap-fit ​​structure of the second connecting plate and the first connecting plate bracket to achieve assembly therebetween. After the circuit board is completely inserted into the mounting plate body, the second connecting hole and the first connecting hole maintain a one-to-one correspondence, thereby facilitating subsequent bolt connection.

[0016] 2. In the present invention, an embedded PCB circuit board is provided.
