The utility model discloses it is provided with a plurality of reference columns to set up to be provided with in the lower cover, just forms the erection column to the position of reference column in the upper cover, the upper cover passes reference column and erection column in proper order through the screw and fixes under covering.

The utility model discloses further set up to be connected with the division board between the lateral wall of erection column and upper cover, the lateral wall of erection column, upper cover, division board surround and form the compartment, the barb is connected at the compartment intracavity.

The positioning column and the mounting column are used for fixing the upper cover and the lower cover, the separation cavity is formed by the mounting column, the side wall of the upper cover and the partition plate in a surrounding mode, the barb of the U-shaped wire frame can be independently arranged in the separation cavity, and the problem of electric leakage caused by error connection of an internal electric wire and the U-shaped wire frame is avoided.

This practicality further sets up to the inside sunken interface lateral wall that forms of one side lateral wall of lower cover, be provided with net twine interface, USB interface, antenna connection terminal, DB interface and contact pin connection terminal on the interface lateral wall respectively.

The concave interface side wall is convenient for the touch screen to wire, and is provided with various interfaces, so that the requirements of various occasions can be met.

The utility model discloses further set up to be provided with the clamp plate for the symmetry on the PCB board subassembly, the touch-sensitive screen subassembly is connected on the clamp plate.

The pressing plate is used for fixing the PCB assembly and the touch screen assembly, and the positioning reliability of electronic devices in the touch screen is guaranteed.
