Further, the second outer shell is a ring-shaped shell with decoration and protection functions, and wraps the front part of the inner shell and blocks the front end of the first outer shell.
Preferably, the second shell is a ring-shaped metal shell, and the surface of the second shell is smooth.
More preferably, the second housing is a ring-shaped aluminum housing, and the surface of the second housing is a smooth surface formed by electroplating or oxidation.
Further, the second housing has a surface flush with the surface of the first housing, and the front end surface of the second housing is substantially flush with the front end surface of the limit projection.
Furthermore, the inner shell is fixedly combined with the interface plug in an injection molding mode, the second outer shell is directly sleeved on the limiting convex part, the first outer shell is fixedly combined with the inner shell in an injection molding mode, and the second outer shell is clamped at the front part of the inner shell.
The utility model discloses a set up spacing convex part in the front portion of inner shell and be used for spacing for the aluminum hull only need when the assembly from back forward push to the end can, need not to counterpoint specially, then the plastic shell after through the shaping blocks the aluminum hull from the rear end, just so fixed the aluminum hull completely, assembly efficiency is high, need not to use glue, not only save the cost, and there is not the excessive problem that causes the yields to hang down of glue, no matter high temperature or low temperature simultaneously, the structure of aluminum hull is all very firm, can not drop completely.
