DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a PCBA board that is convenient for DIP plug-in, including a PCBA board body 1, two fixed blocks 2 are fixedly connected to the outer right side of the PCBA board body 1, two mounting grooves 4 are opened on the right side of the PCBA board body 1, a limiting groove 3 is opened inside the fixed block 2, a limiting plate 7 is slidably connected inside the limiting groove 3, a push rod 8 is fixedly connected to one side of the limiting plate 7, and a connecting rod 9 is rotatably connected to the other side of the limiting plate 7, a spring 6 is fixedly connected to one side of the limiting groove 3, and a clamping block 10 is fixedly connected to the other end of the spring 6, two mounting blocks 5 are fixedly connected to the outer left side of the PCBA board body 1, a clamping groove 11 is opened on the outer surface of the mounting block 5, and a heat dissipation component 12 is arranged at the bottom of the PCBA board body 1.

[0024] Specifically, electronic components and DIP plug-ins are welded and fixed through the PCBA board body 1 to form an integrated circuit, thereby providing various functions for the electronic device. The two fixing blocks 2 are connected to the PCBA board body 1, so that the fixing blocks 2 can be convenient for the assembly of splicing and installing the board. The limit plate 7 can be pushed to slide inside the limit groove 3 through the push rod 8, so that the connecting rod 9 rotatably connected to one side of the limit plate 7 can be moved, and pressure is applied to the card block 10 through the other end of the connecting rod 9, so that the card block 10 slides toward the inside of the limit groove 3. The spring 6 is fixed through one side of the limit groove 3, so that the spring 6 can drive the card block 10 to move when it is extended and retracted. The card block 10 can be plugged and matched with the card slot 11 through the reset effect of the spring 6, so that the two PCBA boards are connected and fixed. The heat dissipation component 12 can dissipate heat for the PCBA board body 1, thereby ensuring that the electronic components can operate in a stable temperature range and ensuring the operating effect of the electronic components.

[0025] Reference Figure 2 The heat dissipation component 12 includes a heat sink 1202, which is fixedly connected to the bottom of the PCBA board body 1. A plurality of heat dissipation dorsal fins 1203 are fixedly connected to the outer surface of the heat sink 1202. A plurality of heat dissipation holes 1201 are opened on the surface of the PCBA board body 1. The heat sink 1202 is made of copper sheet, and is arranged just below the middle of the PCBA board body 1.

[0026] Specifically, the heat generated by the PCBA board body 1 is transferred through the heat sink 1202, and the heat dissipation area can be increased through multiple heat dissipation dorsal fins 1203, thereby accelerating the heat dissipation efficiency of the PCBA board. The heat sink 1202 is made of copper sheet, which can enhance the thermal conductivity, thereby dissipating the heat of the PCBA board body 1. The multiple heat dissipation holes 1201 can accelerate the air circulation through the board. Under the action of the heat dissipation component 12, it is ensured that the PCBA board and the entire electronic system can dissipate heat well and maintain a suitable working temperature, thereby extending the service life of the equipment.

[0027] Reference Figure 1 and Figure 3 The other end of the connecting rod 9 is externally rotatably connected to one end of the card block 10, the outside of the card block 10 is slidably connected to the inside of the PCBA board body 1, one end of the push rod 8 passes through the outer wall of the fixed block 2, the outside of the push rod 8 is slidably connected to the inside of the fixed block 2, the outside of the mounting block 5 is slidably connected to the inside of the mounting groove 4 corresponding to the same horizontal line, the cross-section of the card block 10 is set to be square, the card block 10 and the card slot 11 are plug-in matched, and the material of the PCBA board body 1 is glass fiber reinforced epoxy resin.

[0028] Specifically, the movement of the connecting rod 9 can cause the card block 10 to slide, so that the card block 10 can slide in the PCBA board body 1 and be inserted into the card slot 11 to complete the plug-in fit, thereby completing the splicing and fixation of the two PCBA boards. The push rod 8 is connected to the internal sliding of the fixing block 2, so that the push rod 8 can move and drive the limit plate 7 to move. The mounting block 5 is engaged with the mounting slot 4 corresponding to the same horizontal line to achieve pre-splicing of the two PCBA boards, and then they can be fixed by the card block 10. The cross-section of the card block 10 is set to a square, so that the card block 10 is more secure when completing the plug-in fit with the card slot 11, and the two PCBA boards will not loosen after being connected. The material used for the PCBA board body 1 is epoxy resin, which has good insulation performance, mechanical strength and high temperature resistance, thereby greatly improving the durability of the board.

[0029] Working principle: When using this PCBA board, if two boards need to be spliced ​​together, the push rod 8 on the fixed block 2 connected to one side of the PCBA board body 1 can be pressed, and the limit plate 7 can be pushed to slide inside the limit groove 3 through the push rod 8. The movement of the limit plate 7 pushes one end of the connecting rod 9 to rotate, and then pressure is applied to the card block 10 through its other end, so that the card block 10 slides toward the inside of the limit groove 3 and the spring 6 contracts. At this time, the two mounting blocks 5 connected to one side of the other PCBA board body 1 can be respectively inserted into the corresponding mounting grooves 4. At this time, the push rod 8 is released, and the spring 6 loses pressure and begins to recover, thereby pushing the card block 10 into the card slot 11 to complete the plug-in fit, thereby fixing the two PCBA boards together and fixing them, which can reduce the space occupied by the board, make the structure more compact, improve the reliability and stability of the system, and at the same time facilitate maintenance and overhaul, reducing maintenance costs. Through the multiple heat dissipation holes 1201 starting from the surface of the PCBA board body 1, the air circulation can be accelerated, the air can pass through the board body, the heat dissipation can be enhanced, and the heat dissipation area can be increased through the cooperation of the heat sink 1202 and the heat dissipation dorsal fin 1203, so that the electronic components on the PCBA board can be maintained at a certain temperature, reducing the impact of temperature and extending the service life of the electronic components.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
