[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] like Figures 1 to 4 As shown, the utility model provides a circuit board 100 that is easy to plug in, which includes a mounting base 10 and a circuit board body 20 mounted on the mounting base 10 .

[0017] The mounting base 10 includes a carrier plate 11, a positioning column 12, a buckle ring 13 and a telescopic spring 14, and a mounting hole 21 penetrating from top to bottom is provided on the circuit board body 20. The lower end of the positioning column 12 is fixedly mounted on the upper surface of the carrier plate 11, the circuit board body 20 is attached to the upper surface of the carrier plate 11 and the mounting hole 21 passes through the positioning column 12, the buckle ring 13 and the telescopic spring 14 are both sleeved on the positioning column 12, and the lower end of the buckle ring 13 abuts against the circuit board body 20, and the two ends of the telescopic spring 14 abut against the upper end of the positioning column 12 and the upper end of the buckle ring 13 respectively.

[0018] When the insertion angle of the circuit board needs to be adjusted, the buckle ring 13 only needs to be manually lifted to release the limit fixation on the circuit board body 20, and then the circuit board is rotated. After the adjustment is completed, the buckle ring 13 is restored to the top of the circuit board body 20 to fix the circuit board again.

[0019] The circuit board body 20 includes a main body 22 and a plurality of plug-in ports 23 disposed on the main body 22. The main body 22 is attached to the upper surface of the carrier board 11, and the plurality of plug-in ports 23 are disposed on the left and right sides of the main body 22. The left and right sides of the main body 22 are also provided with sliding adjustment grooves 221, respectively, and the plurality of plug-in ports 23 are respectively engaged and installed in the sliding adjustment grooves 221 and can be slidably adjusted forward and backward. The sliding adjustment grooves 221 can support the forward and backward sliding adjustment position of the plug-in ports 23, so that the positions of the ports and the wire terminals are more corresponding, and the bending operation when the wires are plugged in is further reduced.

[0020] The main body 22 is also provided with a plurality of positioning teeth 222, and the bottom of the buckle ring 13 is correspondingly provided with a plurality of positioning slots 131, and the plurality of positioning teeth 222 are distributed in a ring shape around the periphery of the mounting hole 21, and the plurality of positioning slots 131 are correspondingly engaged with the plurality of positioning teeth 222. The engagement of the positioning teeth 222 with the positioning slots 131 can further enhance the positioning effect between the circuit board body 20 and the mounting base 10, and prevent the circuit board from being deflected or even loosened due to factors such as vibration.

[0021] The circuit board body 20 also includes a fixing clip 24, which is arranged on the outside of the sliding adjustment groove 221 and the plug port 23. When the wire is plugged in, it can first pass through the fixing clip 24 and then connect to the plug port 23. After the connection is completed, the wire can be clamped and fixed by the fixing clip 24, so that the risk of it being pulled and loosened from the plug port 23 is greatly reduced. The bottom of the carrier board 11 is also provided with a plurality of heat dissipation grooves 111 that are crisscrossed and the ends extend to the outside, and the heat dissipation grooves 111 are also provided with a plurality of heat dissipation holes 112 that penetrate the carrier board 11 from top to bottom. The heat dissipation grooves 111 and the heat dissipation holes 112 at the bottom of the carrier board 11 are more convenient for heat dissipation of the circuit board body 20 during operation, reducing the hindering effect of the carrier board 11 body on the heat dissipation capacity of the circuit board.

[0022] In summary, the beneficial effects of the utility model of a circuit board 100 that is easy to plug in are: by designing a circuit board with a rotatable and adjustable installation angle, the angle can be adjusted according to the direction of the wire end when installing the plug-in wire, which greatly improves the problem of excessive bending and winding of the wire when the circuit board is wired; the plug-in port 23 is designed to be slidable and adjustable, which can further match the plug-in position of the wire terminal; the positioning tooth 222 and the positioning groove 131 can strengthen the positioning effect between the carrier plate 11 and the circuit board body 20, and avoid the circuit board from loosening due to vibration and other factors after installation; the fixing clip 24 on the circuit board body 20 can further fix the wire plugged into the circuit board, greatly reducing the risk of the wire being pulled and loosened from the plug-in port 23; the heat dissipation structure on the carrier plate 11 can improve the heat dissipation effect of the circuit board being affected by being blocked by the base; the utility model is highly practical and has a strong promotional significance.
