Description

Novel plug-in type circuit board Technical Field The utility model belongs to the technical field of electronic equipment, and particularly relates to a novel plug-in type circuit board. Background In electronic devices, the plug connection of a circuit board to an electrical appliance is a common assembly. However, the conventional plug-in circuit board has the following problems: 1. The plug lacks guide structure with the joint, easily leads to the contact failure because of the angle deviation when pegging graft by the manual work, damages the pin even. 2. The contact between the plug-in parts is prone to heat build-up, which can lead to component aging or failure, especially during high-power operation. 3. Only rely on the mechanical connection of plug and joint, easily become flexible under vibration or external force effect influences equipment reliability. Therefore, a novel plug-in type circuit board is provided to solve the above problems. Disclosure of utility model The utility model aims to solve the technical problems of inconvenient plugging, insufficient heat dissipation and unstable connection of the traditional plug-in type circuit board. In order to achieve the functions, the novel plug-in type circuit board comprises an electric appliance and a circuit board body arranged on one side of the electric appliance, wherein a plug is fixedly arranged at one end of the electric appliance, a connector matched with the plug is arranged on the circuit board body, a guide assembly is arranged at one end of the electric appliance, the guide assembly comprises a guide shell sleeved on the outer side of the plug and connected to one end of the electric appliance in a sliding mode, and a refrigerating assembly is arranged at the lower end of the guide shell. Further, the guide assembly comprises two magnetic blocks fixedly arranged at one end of the guide shell, and a magnetic hole for sucking the magnetic blocks is fixedly formed in one end of the circuit board body. Further, the two magnetic blocks and the magnetic holes are diagonally arranged. Further, the refrigerating assembly comprises two refrigerating sheets which are fixedly embedded and oppositely arranged at the lower end of the guiding shell, and a plurality of round holes matched with the refrigerating sheets are formed in the upper end of the guiding shell. Further, connecting strips are fixedly connected to two sides of the plug, sliding blocks are fixedly connected to the connecting strips, a plurality of groups of rectangular grooves are formed in two side walls of the guide shell, and the sliding blocks horizontally slide at the rectangular grooves in the center.
