Abstract

The present invention provides a circuit board floating interconnection method, belonging to the technical field of displays. One of two circuit boards is set in floating installation through a mechanical structure, so that the degree of freedom of the circuit board in a certain direction is limited, and the circuit board moves only within a certain range of the other two degrees of freedom. In addition, an oriented positioning mechanism is arranged. Before the other circuit board and the floating circuit board are interconnected, blind interconnection between the two circuit boards is carried out safely and accurately through conduction of the oriented positioning mechanism. Compared with hard interconnection of traditional circuit boards, floating interconnection of the circuit board eliminates size errors caused by machining, so that connectors are interconnected accurately, a plug pin of the connector is not damaged, a connection stress between the circuit boards is eliminated, signal transmission between the circuit boards is more stable, and risks of damage and falling of the connector caused by stress are lowered.

Description

technical field [0001] The invention relates to a method for floating and inserting circuit boards, which belongs to the technical field of displays. Background technique [0002] The connection between the circuit boards inside the existing display usually adopts a cable connection or a hard plug-in connection of the circuit boards to realize the intercommunication of the internal circuit boards. The cable connection method takes up a lot of space inside the display, and it is not convenient for the reasonable layout of the internal structure of the display. When using cable connection, the cable needs to be fixed, and there is a certain risk of failure of the cable after working for a certain period of time; the circuit board The hard mating of the connectors avoids the disadvantages caused by the cable connection. However, when the circuit board is connected blindly, due to the unavoidable machining error, the connectors on the circuit board cannot be completely aligned. ...
