Description

Technical Field

[0001] This utility model relates to the field of PCBA electronic circuit board technology, specifically a combined PCBA electronic circuit board. Background Technology

[0002] PCBA is a circuit board that is made by printing solder paste onto a PCB and then installing various components such as resistors, integrated circuits, capacitors and transformers according to the purpose and required characteristics of the circuit board. In the process of PCBA electronic circuit board assembly, multiple PCBA electronic circuit boards are assembled.

[0003] In the "A Combined Electronic Circuit Board" authorized by publication number "CN222339800U", two PCBA electronic circuit boards are assembled and fixed by two first mounting brackets and two second mounting brackets. However, the two first mounting brackets and the two second mounting brackets cannot be connected to each other. They are only indirectly connected by the compression of the circuit boards by the first and second mounting brackets, resulting in poor installation stability of the entire device. At the same time, when the first and second mounting brackets on the same side are connected, they are only connected by the first sliding rod and the second mounting bracket sliding rod. This can cause bending at the connection between the first sliding rod and the second mounting bracket sliding rod. Furthermore, when the circuit board is installed between the two first mounting brackets and the two second mounting brackets, the compression fixing method on the first and second mounting brackets can cause compression damage to the circuit board.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a combined PCBA electronic circuit board includes two first mounting brackets 1 and two second mounting brackets 2. The first mounting brackets 1 and second mounting brackets 2 are rotatably connected. PCBA electronic circuit boards are mounted between the two first mounting brackets 1 and between the two second mounting brackets 2. Connecting rods 3 are mounted on the upper surfaces between the two first mounting brackets 1 and between the two second mounting brackets 2. Positioning blocks 4 are symmetrically mounted on the middle of one side of each of the first mounting brackets 1 and the second mounting bracket 2. A positioning groove 16 is formed at one corner of each positioning block 4. The PCBA electronic circuit board is positioned between the four positioning blocks 4, with its four corners located inside the positioning grooves 16. Positioning rods 5 are mounted between the sides of the first mounting brackets 1 and the second mounting brackets 2 on the same side to hold the PCBA electronic circuit board in place. The four corners of the board are installed inside the positioning grooves 16 of the four positioning blocks 4 between the two first mounting brackets 1 and the two second mounting brackets 2. The position of the PCBA electronic circuit board can be fixed by the four positioning blocks 4 to prevent squeezing damage to the PCBA electronic circuit board. When the PCBA electronic circuit board is installed between the two first mounting brackets 1 and the two second mounting brackets 2, the two first mounting brackets 1 and the two second mounting brackets 2 are connected by the connecting rod 3. The position between the two first mounting brackets 1 and the two second mounting brackets 2 is fixed by the connecting rod 3, which can improve the stability of the connection between the two first mounting brackets 1 and the two second mounting brackets 2. When the first mounting brackets 1 and the second mounting brackets 2 are bent, the bending angle of the first mounting brackets 1 and the second mounting brackets 2 is fixed by the positioning rod 5, which improves the stability of the connection when the first mounting brackets 1 and the second mounting brackets 2 are bent.

[0024] like Figures 1 to 5 As shown, the connecting rod 3 includes a first mounting rod 31 and a second mounting rod 32. One end of the first mounting rod 31 and the second mounting rod 32 are respectively mounted on the surface of one of the two first mounting brackets 1. A first fixing bolt 6 is installed in the middle of the first mounting rod 31 and the second mounting rod 32. The first fixing bolt 6 passes through the first mounting rod 31 and the second mounting rod 32 and is fixed to the first mounting rod 31 and the second mounting rod 32. Bolt holes 7 are provided at equal intervals on the surface of the first mounting bracket 1. Mounting bolts 8 are installed at the ends of the first mounting rod 31 and the second mounting rod 32. The mounting bolts 8 pass through the first mounting rod 31 and the second mounting rod 32 and are threadedly connected to the bolt holes 7.

[0025] When a PCBA electronic circuit board is installed between two first mounting brackets 1 and two second mounting brackets 2, a connecting rod 3 connects the two first mounting brackets 1 and the two second mounting brackets 2. The first mounting rod 31 and the second mounting rod 32 are crossed and kept at one point of overlap. The first fixing bolt 6 can control the first mounting rod 31 and the second mounting rod 32 to fix the position between the two first mounting brackets 1 and the two second mounting brackets 2. The ends of the first mounting rod 31 and the second mounting rod 32 can be installed at different bolt holes 7 on the first mounting brackets 1 and the second mounting brackets 2. The first mounting rod 31 and the second mounting rod 32 are fixed at different bolt holes 7 on the first mounting brackets 1 and the second mounting brackets 2 by mounting bolts 8. This ensures that the connecting rod 3 can effectively fix the two first mounting brackets 1 and the two second mounting brackets 2 when installing PCBA electronic circuit boards of different sizes.

[0026] like Figures 1 to 5 As shown, the positioning block 4 is slidably installed on one side of the first mounting bracket 1 and the second mounting bracket 2. A second fixing bolt 9 is installed inside the positioning block 4. The second fixing bolt 9 passes through the positioning block 4 and the first mounting bracket 1 or the positioning block 4 and the second mounting bracket 2.

[0027] Adjust the distance between the two positioning blocks 4 in the middle of the first mounting bracket 1 and the second mounting bracket 2 according to the length and width of the PCBA electronic circuit board, and adjust the distance between the two first mounting brackets 1 and the distance between the two second mounting brackets 2. The positioning blocks 4 can be fixed to the middle of one side of the first mounting bracket 1 and the second mounting bracket 2 by the second fixing bolt 9, so that PCBA electronic circuit boards of different sizes can be installed.

[0028] like Figures 1 to 5 As shown, a first connecting block 10 is integrally provided at one end of the second mounting bracket 2, and a second connecting block 11 is installed at one end of the first mounting bracket 1. A third fixing bolt 12 is provided between the ends of the first connecting block 10 and the second connecting block 11. The third fixing bolt 12 is used to fix the ends of the first connecting block 10 and the second connecting block 11. A movable groove 13 is provided inside one end of the first mounting bracket 1, and one end of the second connecting block 11 is slidably installed inside the movable groove 13.

[0029] The first connecting block 10 on the second mounting bracket 2 and the second connecting block 11 on the first mounting bracket 1 can be fixed by the third fixing bolt 12.

[0030] like Figures 1 to 5As shown, the outer sides of the first mounting bracket 1 and the second mounting bracket 2 are both provided with nut grooves 14. The nut grooves 14 on the first mounting bracket 1 and the second mounting bracket 2 are slidably installed with fourth fixing bolts 15. The fourth fixing bolts 15 on the first mounting bracket 1 and the second mounting bracket 2 are respectively provided to pass through the end of the positioning rod 5.

[0031] The nuts on the fourth fixing bolts 15 on the first mounting bracket 1 and the second mounting bracket 2 slide inside the nut groove 14, and the two ends of the positioning rod 5 are fixed on the first mounting bracket 1 and the second mounting bracket 2 by the fourth fixing bolts 15. The bending angle of the first mounting bracket 1 and the second mounting bracket 2 can be effectively fixed by the positioning rod 5, thereby improving the stability of the connection when the first mounting bracket 1 and the second mounting bracket 2 are bent.

[0032] This utility model provides a combined PCBA electronic circuit board, the specific working principle of which is as follows:

[0033] When using the device, the distance between the two positioning blocks 4 in the middle of the first mounting bracket 1 and the second mounting bracket 2 is adjusted according to the length and width of the PCBA electronic circuit board. The distance between the two first mounting brackets 1 and the distance between the two second mounting brackets 2 are also adjusted. The four corners of the PCBA electronic circuit board are installed in the positioning grooves 16 of the four positioning blocks 4 between the two first mounting brackets 1 and the two second mounting brackets 2. Then, the positioning blocks 4 are fixed in the middle of one side of the first mounting bracket 1 and the second mounting bracket 2 by the second fixing bolts 9. PCBA electronic circuit boards of different sizes can be installed, and the position of the PCBA electronic circuit board can be fixed by the four positioning blocks 4 to prevent the PCBA electronic circuit board from being squeezed and damaged.

[0034] When installing PCBA electronic circuit boards between two first mounting brackets 1 and two second mounting brackets 2, connecting rods 3 connect the two first mounting brackets 1 and the two second mounting brackets 2. The first mounting rods 31 and the second mounting rods 32 are crossed and kept at one point of overlap. The first fixing bolts 6 can control the first mounting rods 31 and the second mounting rods 32 to fix the first mounting rods 31 and the second mounting brackets 2. The connecting rods 3 formed by the first mounting rods 31 and the second mounting rods 32 fix the position between the two first mounting brackets 1 and the two second mounting brackets 2, which can improve the stability of the connection between the two first mounting brackets 1 and the two second mounting brackets 2. The ends of the first mounting rods 31 and the second mounting rods 32 can be installed at different bolt holes 7 on the first mounting brackets 1 and the second mounting brackets 2. The first mounting rods 31 and the second mounting rods 32 are fixed at different bolt holes 7 on the first mounting brackets 1 and the second mounting brackets 2 by mounting bolts 8. When installing PCBA electronic circuit boards of different sizes, the connecting rods 3 can effectively fix the two first mounting brackets 1 and the two second mounting brackets 2.

[0035] When bending between the first mounting bracket 1 and the second mounting bracket 2, the first connecting block 10 on the second mounting bracket 2 and the second connecting block 11 on the first mounting bracket 1 can be fixed by the third fixing bolt 12. At the same time, the positioning rod 5 can be adjusted to rotate by the nut on the fourth fixing bolt 15 on the first mounting bracket 1 and the second mounting bracket 2 sliding inside the nut groove 14. The two ends of the positioning rod 5 are fixed on the first mounting bracket 1 and the second mounting bracket 2 by the fourth fixing bolt 15. The bending angle of the first mounting bracket 1 and the second mounting bracket 2 can be effectively fixed by the positioning rod 5, thereby improving the stability of the connection when the first mounting bracket 1 and the second mounting bracket 2 are bent.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
