DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer toFIGS.1-4, whereFIG.1is an oblique top elevational view of the present invention,FIG.2is an oblique bottom elevational view of the present invention,FIG.3is a sectional top view of the present invention, andFIG.4is a sectional elevational view of the present invention. As illustrated, the two-stage rear cover structure of integrated female connector of the present invention mainly comprises a core body1, a plurality of terminals2and a shielding shell3. The connection relationship of the aforementioned components is as follows:

The core body1comprises a tongue portion11with a plurality of slits110, a step-shaped stopper portion12extended downward from one side of the tongue portion11, and positioning portion13extended from a bottom side of the stopper portion12for positioning.

The plurality of terminals2are arranged in the core body1. The terminals2each have a butt end21located on one side thereof and respectively extending in one respective slit110of the tongue portion11, and a soldering end22located on an opposite side thereof and extending out of the positioning portion13for electrical connection of a preset electronic device (such as desktop computer, notebook computer, or tablet electronic equipment).

The shielding shell3is a metal shell. The shielding shell3comprises a shell body31, an accommodating space310defined in the shell body31for accommodating the core body1, an opening311pierced through one side of the shell body31to the accommodating space310to accommodate the tongue portion11, a docking port312located on the shell body31opposite to the opening311and penetrating through the accommodating space310, a rear cover portion313extended from one side of the shell body31in the direction of the docking port312, and a fixing portion314extended from an opposite bottom side of the rear cover portion313for accommodating the positioning portion13of the core body1.

Please refer toFIGS.3-6, whereFIG.3is a sectional top view of the present invention,FIG.4is a sectional elevational view of the present invention,FIG.5is a rear side view of the present invention, andFIG.6is a sectional side view of the present invention.

It can be clearly seen from the figures that when the two-stage rear cover structure of integrated female connector of the present invention is to be assembled, the terminals2are first formed in the core body1through the insert molding process, so that the butt ends21of the terminals2are respectively penetrated into the slits110of the tongue portion11, and the soldering ends22of the terminals2penetrate the surface of the positioning portion13of the core body1. Then, pass the assembled core body1in the accommodating space310of the shielding shell3to insert the tongue portion11of the core body1into the opening311on the shell body31of the shielding shell3and to accommodate the step-shaped stopper portion12of the core body1in the docking port312on the shell body31of the shielding shell3and also to accommodate the positioning portion13of the core body1in the fixing portion314of the shell body31of the shielding shell3.

After the positioning of the two-stage rear cover structure of integrated female connector of the present invention is completed, the rear cover portion313of the shielding shell3is processed to provide a plurality of folded portions3131bent downward from the shell body31, a stepped portion3132connected to the folded portions3131and attached to the stepped surface on the step-shaped stopper portion12, and an extension portion3133extending downward from the stepped portion3132and attached to the non-stepped wall surface of the step-shaped stopper portion12. In this way, the shielding shell3completely covers the core body1and the plurality of terminals2to avoid the interference of electromagnetic waves from external parts and achieve the effect of shielding electromagnetic waves. Through the above-mentioned position of the stepped portion3132against the step-shaped stopper portion12, it is possible to prevent the present invention from receiving a thrust force to cause the core body1to retreat and shake during butting when a predetermined male connector (not shown) is inserted and connected.

The rear cover portion313will have a gap portion315in the process of manufacturing, the gap portion315can make the rear cover portion313easier to bend during the process, and a connecting portion3134(as shown inFIG.5) with a reinforcing structure to prevent excessive expansion of the gap portion315is formed between the extension portion3133of the rear cover portion313. After the rear cover portion313is bent and attached to the step-shaped stopper portion12, laser welding can be performed on at least one welding point3135provided on one side of the rear cover portion313to further strengthen the strength and fixation of the rear cover portion313. Both sides of the extension portion3133are respectively bent and extended with a side portion3136that is attached to one respective outer wall surface of the shell body31, and the side portion3136is provided with a button hole3137for a respective Z-shaped buckle block316provided on each of the two opposite outer wall surfaces of the shell body31to be snapped and positioned (as shown inFIGS.3and4), so that the rear cover portion313can more stably locate the position of the core body1.

The present invention mainly utilizes the rear cover portion313integrally formed on the shielding shell3to be bent down and positioned at the step-shaped stopper portion12of the core body1by post-processing. By welding the at least one welding point3135provided on the rear cover portion313of the shell body31to strengthen the structure of the gap portion315arranged on the rear cover portion313, so that the shell body31and the rear cover portion313will not be impacted and displaced by the insertion force of the preset male connector. The position of the step-shaped stopper portion12of the core body1is covered by the stepped portion3132and the extension portion3133of the rear cover portion313in large quantities, so as to avoid the interference of electromagnetic waves from external parts. The invention takes advantage of the one-piece construction of the shielding shell3to save the cost and time of additional assembly.

When the two-stage rear cover structure of integrated female connector of the present invention is applied in practice, the above description is only a preferred embodiment of the present invention, and therefore does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the description and drawings of the present invention shall be similarly5included in the patent scope of the present invention.
