Description

Technical Field

[0001] The utility model belongs to the technical field of PCBA boards, and in particular relates to an external PCBA board. Background Art

[0002] PCBA motherboard is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. It is also called a printed circuit board, or printed circuit board. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the advent of printed circuit boards, the interconnection between electronic components was done by direct wire connection to form a complete circuit.

[0003] Existing PCBA boards are mostly tightened by four corner screws, and frequent disassembly and assembly will cause a certain degree of damage to the board. In order to facilitate the disassembly and assembly of the PCBA board, some PCBA boards in the prior art are installed by using arc pieces and elastic pieces. When the PCBA board needs to be disassembled, due to the elastic force of the arc pieces and the elastic pieces, the PCBA board needs to be removed with the help of external force, which may cause damage to the PCBA board.

[0004] Reference to the Chinese authorized patent with authorization announcement number: CN220674159U: An external PCBA board. The utility model uses springs, support plates and support columns to reduce the impact force on the PCBA board body in the vertical direction, and uses elastic sheets to reduce the impact force on the PCBA board body in the horizontal direction, so as to prevent the impact force generated by external vibration on the PCBA board from damaging the components on the PCBA board.

[0005] However, it also has the above-mentioned problem that the PCBA board is fixed by the arc sheet and the elastic sheet. When the PCBA board needs to be disassembled, due to the elastic force of the arc sheet and the elastic sheet, the PCBA board needs to be removed with the help of external force, and the external force may cause damage to the PCBA board. Utility Model Content

[0008] The bottom wall of the inner cavity of the mounting seat is symmetrically provided with two mounting holes, and a micro damping buffer for supporting the support plate is installed in the mounting holes of the mounting seat, and fixing holes are provided at the four corners of the bottom wall of the inner cavity of the mounting seat, a fixing sleeve is fixed in the fixing hole of the mounting seat, a buffer spring is provided in the fixing sleeve, a limit block movably connected to the fixing sleeve is provided on the surface of the buffer spring, and a support column fixedly connected to the support plate is fixed on the surface of the limit block.

[0009] In a further embodiment, a reinforcing rod is fixed in the support plate, rotation grooves are provided on the outer walls around the support plate, and limiting balls are rotatably connected in the rotation grooves of the support plate.

[0010] In a further embodiment, positioning sleeves are fixed to the outer walls on both sides of the mounting seat, a positioning rod is movably connected inside the positioning sleeve, and a connecting block fixedly connected to the limiting cover is fixed to the top of the positioning rod.

[0011] In a further embodiment, a guide hole is formed on one side outer wall of the positioning sleeve, and a positioning pin is movably connected in the guide hole of the positioning sleeve, and a positioning hole matching the positioning pin is formed on one side outer wall of the positioning rod.

[0012] In a further embodiment, a limiting ring is fixed to the outer wall of the positioning pin, and a fixing spring for supporting the limiting ring is sleeved on the outer wall of the positioning pin, and a pulling block is fixed to the end surface of the positioning pin outside the positioning box.

[0013] In a further embodiment, a mounting sleeve is fixed to the outer wall of the mounting seat, and threaded holes are formed at four corners of the mounting sleeve.

[0014] Technical effects and advantages of the utility model:

[0015] The external PCBA board is provided with a buffer spring. When the PCBA board body needs to be disassembled, the limit cover is removed, and the buffer spring pushes the limit block and the support column to rise, thereby pushing the support plate and the PCBA board body to rise, and the PCBA board body is pushed out of the mounting seat. The PCBA board body does not need to be disassembled by external force, thereby avoiding damage to the PCBA board body due to external force.

[0016] The PCBA body can be wrapped by the mounting seat and the limit cover, which can protect it during transportation and reduce the probability of damage. The buffer spring and the micro damping buffer can absorb the vibration of the mounting seat, thereby further ensuring the safety of the PCBA body during transportation.

[0017] The PCBA board body is placed in the mounting seat, the protective cover is covered on the surface of the mounting seat, the fixing spring supports the limit ring, and the positioning pin is inserted into the positioning rod, so that the mounting seat and the limit cover can be quickly connected, so that the PCBA board body can be quickly installed.
