Preferably, the side view diameter of first cambered surface is a centimetre, and the radian of first cambered surface is laminated with the side end face radian of forefinger, conveniently pulls out and inserts in-process forefinger card and go into in the second arc wall to make things convenient for the forefinger to exert oneself.

Preferably, the side-looking diameter of the second arc surface is five millimeters, and the fillet structure at the bottom of the second arc groove prevents the forefinger from being scratched by the edge of the arc groove in the holding process.

Preferably, the bottom of the first arc-shaped groove is tangent to the upper end face side of the plug, the top of the second arc-shaped groove is tangent to the lower end face side of the plug, so that a sufficient gap is reserved between the first arc-shaped groove and the second arc-shaped groove to pass through a plug line, and the overall thickness of the shell is not influenced too much.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a structural design of first arc wall and second arc wall makes things convenient for thumb and forefinger cooperation to grip to make things convenient for inserting and extracting of plug, and the design of the different shapes of upper and lower terminal surface conveniently distinguishes the last lower extreme of plug, thereby more makes things convenient for the plug accuracy to insert in the USB slot.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is an isometric view of the present invention;

fig. 3 is a side view of the present invention.

In the figure: 1 shell, 11 first arc-shaped groove, 111 antislip strip, 12 second arc-shaped groove, 121 first arc-shaped surface, 122 second arc-shaped surface, 13 sealing ring and 2 plug.

Detailed Description

Please refer to fig. 1, a novel USB connector includes a plug 2 and a housing 1, the housing 1 is wrapped on the outer end face of the bottom of the plug 2, a sealing ring 13 is glued at the joint of the plug 2 and the housing 1, a first arc-shaped groove 11 is formed on the upper end face of the housing 1, an anti-slip strip 111 is welded on the upper end face of the first arc-shaped groove 11, a second arc-shaped groove 12 is formed on the lower end of the housing 1, the second arc-shaped groove 12 is composed of a first arc-shaped surface 121 and a second arc-shaped surface 122, and the first arc-shaped surface 121 is tangent to the second arc-shaped surface 122.
