In the production practice, there are many structural designs that need the assembly winding displacement to intelligent bluetooth speaker is the example, and the winding displacement passes through the winding displacement socket to be fixed on the PCB board, fixes in the upper cover together with the PCB board, and the winding displacement belongs to free state this moment. When the upper cover and the shell are installed next, the flat cable cannot be kept in a free and messy state, and the flat cable needs to be limited and fixed. In the prior art, the flat cable is limited and fixed by arranging a hole structure on the housing, through which the flat cable can pass, and the hole structure is generally called as a cable passing hole by a person skilled in the art. After the flat cable passes through the wire passing hole, the hot melt adhesive is smeared around the wire passing hole, so that the purpose of limiting and fixing the flat cable is achieved, and the flat cable is prevented from being messy or pulled to be loose.

Because of the simplicity and convenience of the fixing method, those skilled in the art have been used to the technical means of the spacing and fixing flat cable.
