Description

Technical Field

[0001] The utility model belongs to the field of circuit boards, and in particular relates to a spliced ​​circuit board. Background Art

[0002] A circuit board, also known as a printed circuit board, is a support that connects electronic components and circuits together. It is used to realize the layout design of complex circuits and electrical signal transmission in electrical and electronic equipment. It usually uses glass fiber as the base material and is processed through copper cladding, gold plating, etching and other processes. A circuit board is a basic electronic device used to build and arrange circuit components with a circuit diagram. It consists of a multi-layer printed circuit board, including one or more metal layers, plastic layers, insulation layers and control layers.

[0003] According to a Chinese patent with publication number "CN216673384U", a spliced ​​flexible circuit board is disclosed, which includes a base, a moving mechanism and a connecting mechanism. A first circuit board and a second circuit board are respectively arranged on the top of the base; the moving mechanism is located on one side of the second circuit board, and the moving mechanism includes a moving box, a connecting plate and a card plate. The outer sides of the connecting plate and the card plate are both slidably connected to the inside of the moving box; the connecting mechanism is located on one side of the first circuit board, and the connecting mechanism includes a fixed box.

Although a certain splicing effect is achieved through the above, the splicing convenience of the above-mentioned rotating shaft is single, and the circuit boards can only be spliced ​​horizontally, which reduces the practicality of the device. For this reason, a circuit board that can be spliced ​​vertically is proposed. Utility Model Content
