Description

Technical Field

[0001] The utility model relates to the technical field of semi-circuit connection, in particular to a welding-free connection structure of a vehicle-mounted display screen touch control system. Background Art

[0002] Nowadays, in order to meet the general applicability of the majority of users, some functions are not installed in the cars when they leave the factory. If the user needs to meet their own requirements, they need to add them by themselves or buy high-end models. For example, most original cars do not have the 360-degree panoramic monitoring function. If the car owner wants to realize this function, it is necessary to analyze the data of the original car and connect the circuit board of the 360-degree panoramic monitoring function with the circuit board of the original car's on-board touch screen. In the existing technology, when connecting the circuit board of the 360-degree panoramic monitoring function with the circuit board of the original car's on-board touch screen, it is necessary to weld and adjust the circuit of the original car, and it is necessary to use an external welding machine for welding operations, which is not only cumbersome to operate, but also increases the workload.

The thickness of the conductive sheet 53 is less than the height of the solder joint 3, and the outer surface of the solder joint 3 is in contact with the inner wall of the groove 54. The inside of the groove 54 is filled with conductive silicone.
