Description

Technical Field

[0001] The present invention relates to a circuit board, and in particular to a circuit board which is convenient for assembly and disassembly. Background Art

[0002] Circuit boards are typically secured with screws, making assembly and disassembly very cumbersome, and can easily cause thread slippage after repeated disassembly and assembly. This is especially true for products like mobile phones, which have extremely compact internal structures. The screws used for circuit boards are very small, further increasing the difficulty of assembly and disassembly, necessitating improvements. Summary of the Invention

[0003] The object of the present invention is to provide a circuit board that is easy to assemble and disassemble. The installation and disassembly of the PCB board are very convenient and no faults such as thread slippage will occur.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circuit board that is easy to disassemble and assemble, comprising a PCB and a base, wherein the PCB is provided with a through hole, and the base is provided with a blind hole opposite to the through hole, and further comprising a frame, wherein the frame is provided with a plurality of columns, each of the columns is arranged opposite to one of the blind holes, and the columns are inserted downward into the blind holes, and the frame and the base clamp the PCB. When installing a circuit board of this structure, the PCB is placed on the base so that the through hole and the blind hole are opposite, and then the frame is placed on the PCB, and each column is pressed into the blind hole, thus achieving installation. When disassembling, it is even simpler, and all the columns can be pulled out of the blind holes by simply pulling up the frame along any end of the frame, thereby completing the disassembly. In this way, the installation and disassembly of the PCB are very convenient, and there will be no problems such as thread slippage.

[0005] As a preferred embodiment of the present invention, a protrusion is provided on the base, the blind hole is provided in the protrusion, and the protrusion abuts against the bottom of the PCB board.

[0006] As a preferred embodiment of the present invention, a shock-absorbing pad is provided on the top of the protrusion to prevent the PCB from being damaged when the product is impacted.

[0007] As a preferred embodiment of the present invention, a cover plate is further included, which is fixed to the base and presses the top of each column. The cover plate can further prevent the column from falling out of the blind hole.

[0008] As a preferred embodiment of the present invention, a handle is provided at one end of the frame. When disassembling, a person can pull the handle upwards to pull out all the columns on the frame from the blind holes.

[0009] As a preferred embodiment of the present invention, the frame is made of a material with good toughness.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When installing a circuit board with this structure, place the PCB on the base so that the through-holes and blind holes are aligned. Then place the frame on the PCB and press each column into the blind hole to complete the installation. Disassembly is even simpler: simply pull up the frame along any end to pull all the columns out of the blind holes, completing the disassembly. This makes installation and removal of the PCB very convenient and prevents problems such as thread slippage. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0018] See also Figure 1-5 , a circuit board that is easy to disassemble and assemble, includes a PCB board 1, a base 2 and a cover board 4. The PCB board 1 is provided with through holes 11, and the through holes are distributed around the circumference of the PCB board.

[0019] The base 2 is provided with a protrusion 21, and a blind hole 22 is provided on the protrusion 21. The blind hole is arranged opposite to the through hole 11. A shock-absorbing pad 23 is provided on the top of the protrusion 21. The shock-absorbing pad plays a role in shock absorption, preventing damage to the PCB board when the product is subjected to impact.

[0020] The device also includes a frame 3 made of a tough material. The frame 3 is provided with multiple columns 31, each of which is positioned opposite a blind hole 22. A handle 32 is provided at one end of the frame 3. During disassembly, the handle can be pulled upward to remove all the columns from the blind holes.

[0021] The column 31 is inserted downward into the blind hole 22. A reinforcement ring 33 is provided on the frame 3 at the column 31, wrapped around the outer circumference of the column. When the column 31 is inserted into the bottom of the blind hole 22, the reinforcement ring 33 presses against the top of the PCB. The protrusion 21 abuts against the bottom of the PCB 1, and the frame 3 and the base 2 clamp the PCB 1.

[0022] The cover plate 4 is fixed to the base 2. Specifically, the base 2 is provided with a circle of panels 24, and the panels 24 are provided with a circle of steps 25. The circumference of the cover plate 4 is glued to the step surface, and the cover plate 3 is pressed against the top of each column 31. The tight pressure of the cover plate can further prevent the column from falling out of the blind hole.

[0023] When installing a circuit board with this structure, place the PCB on the base so that the through-holes and blind holes are aligned. Then place the frame on the PCB and press each column into the blind hole to complete the installation. Disassembly is even simpler: simply pull up the frame along any end to pull all the columns out of the blind holes, completing the disassembly. This makes installation and removal of the PCB very convenient and prevents problems such as thread slippage.
