Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit boards, in particular to a splicable PCB board. Background Art
[0002] PCB (Printed Circuit Board), whose Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components.
[0003] The existing referenceable Chinese utility model patent has a publication number of CN2213847140U, which discloses a spliced PCB board, which relates to a circuit board and aims to solve the problem that PCB boards cannot be spliced together, resulting in a small scope of application of the PCB board. The key points of its technical solution are: it includes a board body, a long side and a wide side of the board body are fixedly connected with a connector, the connector is I-shaped and its recess is used to accommodate the board body to be embedded, a plurality of tooth blocks are fixedly connected in the recess of the connector away from the board body, the tooth block is in the shape of a right-angled triangle, the right-angled side of the tooth block is arranged toward the board body, and the other long side and the wide side of the board body are provided with a plurality of tooth grooves for accommodating the tooth blocks. When people splice PCB boards, the utility model embeds the long side or wide side of the board body into the recessed part of the connecting piece of another board body, the edge of the board body presses the tooth block, so that the connecting piece is deformed, the recessed part of the connecting piece is opened by the edge of the board body, and then the tooth block is embedded in the tooth groove, thereby fixing the two board bodies, improving the application range of the PCB board. When people splice PCB boards, the long side or wide side of the board body is embedded in the recessed part of the connecting piece of another board body, so that the edge of the board body presses the tooth block, thereby causing the connecting piece to be deformed, the recessed part of the connecting piece is opened by the edge of the board body, and then the tooth block is embedded in the tooth groove, thereby fixing the two board bodies, so that both the long side and the wide side of the board body can be fixed, thereby improving the application range of the PCB board. Since the tooth block is in a right-angled triangle, when the board is away from the connecting piece, the inner wall of the tooth groove conflicts with the right-angled side of the tooth block, thereby limiting the movement of the board body, and improving the connection strength between the tooth block and the tooth groove.
[0004] The above-mentioned spliced PCB board solves the problem that more and more functions are required to be achieved in the current design of PCB boards by embedding the long side or wide side of the board body into the recessed part of the connecting piece of another board body. For PCB boards with multiple functions, there are many PCB boards arranged. Currently, the boards cannot be spliced with each other, resulting in the PCB boards occupying more area, increasing the occupied space, and being inconvenient to store and adjust the position of the PCB boards. However, the connection between the boards of the above-mentioned device is relatively weak and is prone to breakage, which affects the use. At the same time, the splicing effect of the above-mentioned device is not good. Utility Model Content
