Background

At present, most of electronic devices such as mobile phones, tablets and digital cameras are charged by connecting a charger through a data line, wherein the data line has two ends, one end of the data line is a connector connected with the charger, and the other end of the data line is a connector connected with the electronic devices. At present, most joints of the data line are all formed by plastic injection molding, the hand feeling experience and the appearance texture are not good enough, the grade is not displayed, and the joints are easy to scratch. In order to solve the problem, it is common practice to sleeve a metal shell (generally made of aluminum alloy) on the plastic shell, and form a plastic shell at the same time, so that the plastic shell is enclosed by the metal shell and the plastic shell, and the metal shell can play a role in decoration, and can play a role in protection of the plastic shell and the plastic shell. At present, the assembly process of a metal shell (or called aluminum shell) generally includes molding a plastic shell (inner shell), then molding a plastic outer shell, and then dispensing a water jacket aluminum shell. The defects of the mode are that the efficiency is low during operation, the glue dispensing water can overflow, the reject ratio is high, and the aluminum shell falls off when meeting high temperature or low temperature at the later stage.

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.
