Embedded line-to-board connection structure

The utility model belongs to the technical field of electrical connection structures, and discloses an embedded wire-to-board connection structure, which is characterized in that a U-shaped wire slot assembly is arranged on a circuit board, and a wire is inserted into the wire slot assembly from an opening of the wire slot assembly and is fixedly connected to one end, connected with a first copper layer, of the wire slot assembly; the thickness of the wire is smaller than or equal to that of the circuit board, so that after the wire is fixedly installed in the wire groove assembly, the two sides of the wire do not exceed the circuit board and can be in the same plane, the wire is embedded into the circuit board, that is, the two sides of the embedded wire-to-board connection structure are not provided with protrusions and lamination, and therefore the space used for wire-to-board connection is reduced, and the wire-to-board connection efficiency is improved. The space utilization rate is improved, and miniatu
