In order to achieve the above object, the electronic device buckle structure of the present invention comprises a circuit board and a connection interface and an actuation interface respectively soldered and fixed on the circuit board, and the outer edge of the connection interface is respectively assembled with an upper and a lower assembly. The first body and the second body are respectively provided with at least one or more pressing portions, and the rear edge of the first body is provided with a buckle protrusion; an outer casing Forming an accommodating space and accommodating the above-mentioned components, wherein the pressing portions of the first body and the second outer peripheral edge are in close contact with the inner edges of the outer casing accommodating space, respectively, and the snap protrusions on the first body are The positioning protrusions in the outer casing are fastened to each other, thereby increasing the buckle strength.

According to the above structure, the connection interface is first assembled and covered by the first body and the second body, and then inserted into the housing space of the outer casing with the circuit board and the actuation interface, and penetrates between the pressing portion and the outer casing. The snap-fit portion is in abutment with the positioning protrusion of the outer casing. When the assembled connection interface is clamped and fixed in the outer casing through the first body and the second body, the connection can be greatly improved. The strength of the plugging and unplugging of the interface ensures the welding stability between the connection interface and the circuit board during the assembly process of the outer casing, which achieves the purpose of the creation.

In order to achieve the other purpose of this creation, the connection interface of the creation is in accordance with the specification of USB TYPE-C, and the actuation interface can be an electrical connector conforming to the USB3.0 specification, so that the creation is a double connection after assembly. The electronic device of the interface; in addition, the actuation interface can also be a storage chip, so that the creation is a portable electronic device after assembly, and the other creation is achieved. purpose.
