Circuit board installation includes electronic component installation and welding as well as circuit board installation. There are two main ways to install electronic components: plug-in and patch. Plugin is to insert electronic components into the sockets of the circuit board and then solder them. Patch is to stick electronic components directly on the surface of the circuit board and then reflow soldering. Circuit board installation is to install the circuit board with installed electronic components inside the equipment box and then connect and lead out the lines.

[0003] In the current existing technology, the circuit board with installed electronic components is installed in the equipment box by fixing screws and threaded barrels welded inside the equipment box. It is necessary to first place the circuit board in a specified position in the equipment box, align the threaded barrel with the hole groove on the circuit board, and then install the circuit board in the spare box by tightening the screws. This installation process is relatively complicated, not only requiring the alignment of the hole grooves on the circuit board, but also requiring the tightening of the screws. Therefore, a circuit board that is easy to install quickly is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 In this embodiment, a circuit board that is easy to install quickly includes a device box 1, a circuit board 2 is arranged inside the device box 1, electronic components 3 are arranged on the circuit board 2, a mounting structure and an auxiliary structure are provided on the circuit board 2, the circuit board 2 is installed inside the device box 1, the electronic components 3 are soldered to the circuit board 2, and a support plate for supporting the circuit board 2 is fixedly installed on the inner bottom wall of the device box 1.

[0021] In the embodiment of this example, the mounting structure includes two support frames 41 installed on the bottom of the circuit board 2, and the two support frames 41 are provided with mounting components 42 for connecting the support frames 41 and the circuit board 2. The two mounting components 42 include fixing screws and locking nuts. One end of the two fixing screws passes through the circuit board 2 and extends to the interior of the support frame 41 on the same side. The locking nuts are threadedly installed on the outer surface of the fixing screws and contact the inner top wall of the support frame 41 on the same side, so as to facilitate the pre-installation of the two support frames 41 on the circuit board 2 to form a prefabricated mounting part of the circuit board 2. The inner bottom walls of the two support frames 41 are fixedly installed with positioning blocks 43, and the inner bottom wall of the equipment box 1 is fixedly installed with two connecting frames 44. The interior of the two connecting frames 44 is slidably installed with a connecting rod 45 with one end passing through and extending to the outside thereof. The opposite sides of the two connecting rods 45 are fixedly installed with a plug-in block 46 with one end inserted into the positioning block 43 and used to position the circuit board 2.

[0022] Among them, a V-shaped groove is opened on the opposite side of the two positioning blocks 43, and one end of the two plug-in blocks 46 respectively passes through and extends to the inside of the V-shaped groove. The inner bottom walls of the two connecting frames 44 are installed with mounting bolts for fixing the connecting device box 1, which facilitates the perfect insertion of the plug-in blocks 46 into the interior of the positioning block 43, thereby fixing the position of the two support frames 41.

[0023] By adopting the above technical solution, two support frames 41 are pre-installed on the bottom of the circuit board 2 using the fixing screws and locking nuts in the installation component 42, thereby making a prefabricated installation part of the circuit board 2. Then, when installing the circuit board 2 and the device box 1, the circuit board 2 is pressed downward so that the two support frames 41 at the bottom of the circuit board 2 squeeze the two plug-in blocks 46 to the opposite side until the support frame 41 contacts the inner bottom wall of the device box 1. Then, under the action of the auxiliary structure, the two plug-in blocks 46 are controlled to be inserted into the interior of the two positioning blocks 43 respectively, thereby quickly completing the installation of the circuit board 2.

[0024] In the embodiment of this example, the auxiliary structure includes two telescopic springs 47 respectively sleeved on the outer surface of the connecting rod 45, and the outer surfaces of the two connecting rods 45 are fixedly installed with limit plates 48. The two limit plates 48 are respectively slidably connected to the inner walls of the two connecting frames 44 to limit the connecting rod 45 to move left and right only inside the connecting frame 44. The top of the two connecting frames 44 is equipped with a positioning component 49 for positioning the circuit board 2. The positioning component 49 includes two positioning columns, and the two positioning columns are respectively fixedly installed on the top of the two connecting frames 44. Two positioning grooves are provided on the circuit board 2. One end of the two positioning columns respectively passes through the interior of the two positioning grooves, which is convenient for limiting the placement and pressing position of the circuit board 2, thereby facilitating installation.

[0025] Among them, the opposite sides of the two telescopic springs 47 are fixedly connected to the inner walls of the two connecting frames 44 respectively, and the opposite sides of the two telescopic springs 47 are fixedly connected to the opposite sides of the two limit plates 48 respectively, so as to provide the force for the two limit plates 48 to move toward the opposite sides, thereby completing the control of the plug-in block 46 to be inserted into the interior of the positioning block 43 and achieving the purpose of fixation.

[0026] By adopting the above technical solution, the circuit board 2 is aligned with the positioning column in the positioning component 49 and then pressed downward, so that the two support frames 41 squeeze the two plug-in blocks 46 to the opposite side, thereby compressing the telescopic spring 47 through the connecting rod 45 and the limit plate 48 until the support frame 41 contacts the inner bottom wall of the device box 1. The two limit plates 48 move to the opposite side under the elastic action of the two telescopic springs 47, thereby controlling the two plug-in blocks 46 to be inserted into the interior of the two positioning blocks 43 respectively.

[0027] The working principle of the above embodiment is:

[0028] The circuit board that is easy to install quickly, when in use, pre-installs two support frames 41 on the bottom of the circuit board 2 using the fixing screws and locking nuts in the installation component 42, thereby making a prefabricated installation component of the circuit board 2, and then installs the circuit board 2 on the device box 1, aligns the circuit board 2 with the positioning column in the positioning component 49 and presses downward, so that the two support frames 41 squeeze the two plug-in blocks 46 to the opposite side, thereby compressing the telescopic spring 47 through the connecting rod 45 and the limit plate 48, until the support frame 41 contacts the inner bottom wall of the device box 1, and the two limit plates 48 move to the opposite side under the elastic action of the two telescopic springs 47, thereby controlling the two plug-in blocks 46 to be respectively inserted into the interior of the two positioning blocks 43, thereby quickly completing the installation of the circuit board 2.
