Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a combined electronic circuit board. Background Art

[0002] Circuit boards can be divided into three categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards.

[0003] The first is the single-sided board. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires only appear on one side, this kind of PCB is called a single-sided circuit board. Single-sided boards are usually simple to make and low in cost, but the disadvantage is that they cannot be applied to too complex products. Double-sided boards are an extension of single-sided boards. When single-layer wiring cannot meet the needs of electronic products, double-sided boards must be used.

[0004] After searching, the existing Chinese patent announcement number is: CN 218830781 U, which provides a combined electronic circuit board. This patent can realize the rapid splicing of electronic circuit boards by setting a combined splicing component and a fastening component. The combined splicing is simple, the connection is stable and firm, the cost is reduced, and the practicability is strong.

[0005] Although the above patent can quickly splice electronic circuit boards, the above-mentioned combined electronic circuit board still has the following problem: the angle of the spliced ​​circuit board cannot be adjusted, which easily causes the circuit board to be unable to be installed inside the shell.

[0006] In view of the above problems, a combined electronic circuit board is proposed. Utility Model Content

[0014] Preferably, a circuit board is slidably connected inside the first mounting frame.
