Description

Technical Field

[0001] The utility model relates to the field of electronic engineering, and specifically relates to a spliced circuit board. Background Art

[0002] A circuit board (abbreviation: PCB) is a planar board used to support and connect electronic components, which includes functions such as conduction, insulation, and mechanical support. As a key component of electronic products, by arranging electrical connections on its surface, the connection, communication, and control between electronic components can be realized. In a circuit board, different electrical layers are connected through vias to achieve signal transmission and power distribution. Spliced circuit boards can provide larger wiring space, better electromagnetic compatibility and anti-interference ability, and at the same time can reduce the size and weight of the circuit board and improve the overall system performance.

[0003] When designing the spliced circuit board of the utility model, the function realization, performance requirements, and interface design of the circuit need to be considered, which can achieve rapid replacement, upgrade, and maintenance of components, and improve the flexibility and maintainability of the system. Knowledge in aspects such as mechanical structure design and connector design is also very important in the design of the spliced circuit board, because the connection method, fixing method, and heat dissipation method of the circuit board will all affect the performance and stability of the system. For this reason, we propose a spliced circuit board. Content of the Utility Model

A plurality of groups of electronic components are arranged at the upper end of the substrate. The sliding plates are slidably installed at both ends of the substrate, and a plurality of groups of limiting structures are installed inside both ends of the substrate.

[0006] Preferably, two fixed magnet rods are fixedly installed on one end face of the substrate, and a first magnet block is fixedly installed on the end face of each fixed magnet rod. A positioning groove is opened on the other end face of the substrate, and a second magnet block is fixedly installed inside the positioning groove.

A plurality of groups of limiting holes are opened inside the sliding plates, and a T-shaped sliding block is integrally formed at one end of the sliding plate.

The special-shaped limiting rod is installed inside the placement groove. A second fixing rod is integrally formed on the special-shaped limiting rod. The spring is sleeved on the second fixing rod and the first fixing rod. The upper end of the special-shaped limiting rod penetrates through the first connection hole, and the lower end of the special-shaped limiting rod penetrates through the second connection hole to complete the connection of the limiting structure.

[0010] Compared with the prior art, the utility model provides a spliced circuit board, which has the following beneficial effects:

[0011] 1. For this spliced circuit board, two fixed magnet rods are fixedly installed on one end face of the substrate. A first magnet block is fixedly installed on the end face of each fixed magnet rod. A positioning groove is formed on the other end face of the substrate. A second magnet block is fixedly installed inside the positioning groove. The first magnet block on one substrate penetrates into the positioning groove on another substrate, and then the fixed magnet rod on the first magnet block corresponds to the second magnet block to closely fit the two substrates.

[0012] 2. For this spliced circuit board, sliding grooves are formed inside both sides of the substrate. A placement groove is formed above the sliding groove. A special-shaped limiting rod, a first fixing rod and a spring are installed inside the placement groove.
