[0001] Slim type metal housing of usb connector [

More particularly, the present invention relates to a metal housing of a slim type USB connector, and more particularly, to a slim-type USB connector metal housing having an upper shield and an upper shield which are hermetically sealed, a front portion thereof is connected to a rear portion, The outer surface of the wire mold to be molded at the rear end portion of the metal housing can be protruded from the outer surface of the front end portion of the metal housing by the same or finely protruded, The present invention relates to a slim-type USB connector metal housing which can reduce the manufacturing cost of the USB connector by reducing the molding material used for molding while manufacturing the USB connector in a slim form.

In general, with the miniaturization and the multifunctionalization of the electronic equipment, the demand for the electrical connector becomes strict, the signal transmission ability is further improved, and the miniaturization and simplification of the structure are required.

Therefore, a universal serial bus (USB) connector (hereinafter referred to as USB connector) is commonly used as an input / output interface.

These USB connectors are available in various specifications such as A type, B type, and MINI type.

In addition, the USB connector as described above is a wire connector, which is used to be connected to one end of a wire.

FIG. 1A is an exemplary view showing a USB connector including a USB connector metal housing according to the prior art, FIG. 1B is a view illustrating a use state of the USB connector metal housing according to the related art, FIG. And FIG. 5 is a view illustrating a state in which a molding process is performed on a rear end portion to which a wire connector is connected, to which a USB connector metal housing according to FIG.

1A and 2B, a conventional USB connector includes a connection mold 10 and a plurality of contact terminals and a metal housing 50, to which a downward wire connection cap is coupled from the upper side to the rear side.

In the conventional USB connector having the above configuration, the plurality of contact terminals are mounted on the connection mold 10, and the metal housing 50 is coupled to surround the outside of the connection mold 10 , And an effect of electromagnetic shielding and the like can be obtained.

In the USB connector as described above, in particular, the metal housing 50 includes the main housing 51 surrounding the connection portion 15 of the connection mold 10, the main housing 51 surrounding the lower portion of the main body of the connection mold 10, And a variable housing 55 connected to the upper portion of the rear portion of the housing 51 so as to be rotatable at a predetermined angle.

In other words, in the conventional metal housing 50 for USB connector, the connection housing 15 is provided with the connecting portion 15 on the inside of the main housing 51 and the lower portion of the body portion on the inside of the main housing 51, And the variable housing 55 is rotated so as to be horizontal with respect to the main housing 51 so as to surround the upper portion of the body of the connection mold 10.

The conventional metal housing 50 for a USB connector as described above is assembled so as to enclose the outside of the connection mold 10 and then the outer surface of the rear end of the main housing 51 of the metal housing 50 and the outer surface of the variable housing 55 The wire mold 70 is molded and used to wrap it.

However, the USB connector connector metal housing according to the related art as described above has a problem in that, compared to the front end of the main housing 51 connected to the USB connector socket of the metal housing 50 after the wire mold 70 is molded, The outer surface of the wire mold 70, which is the rear end portion of the wire 50, protrudes greatly with a step, so that the appearance of the wire is not good, and the wire can not be slimmed with respect to the molding portion.

In addition, since the wire mold 70, which is the rear end portion of the metal housing 50, is not slimmed with respect to the molded portion, there is a problem that the USB connector can not be manufactured in a slim form.

Therefore, the outer surface of the wire mold to be molded at the rear end of the metal housing can be made to be the same as the outer surface of the front end portion of the metal housing, or can be protruded finely, thereby realizing a slimness in the molding process portion. Research and development of a slim type USB connector metal housing that can manufacture a USB connector is required.

Korea public utility model 2008-1197 2008.05.20 open to the public.

In order to solve the above-mentioned problems, the present invention provides an air conditioner comprising: an upper shield which is hermetically sealed at a front portion thereof and a rear portion, The outer surface of the wire mold to be molded at the rear end portion of the metal housing can be protruded from the outer surface of the front end portion of the metal housing by the same or finely protruded, And it is an object of the present invention to provide a slim type USB connector metal housing that can realize slimming.

In addition, according to the present invention, the outer surface of the wire mold, which is molded at the rear end of the metal housing, can be protruded from the outer surface of the front end of the metal housing, So that the USB connector can be manufactured in a slim form.

In addition, according to the present invention, the outer surface of the wire mold, which is molded at the rear end of the metal housing, can be protruded from the outer surface of the front end of the metal housing by finely protruding, And it is an object of the present invention to reduce molding material used for molding a USB connector and to reduce manufacturing cost for manufacturing a USB connector.

The present invention for achieving the above-mentioned objects is as follows.
