Preferably, the included angle is in the range of 30 ° to 60 °.
Preferably, the first side wall and the second side wall are provided with a plurality of fixing holes.
Preferably, the second side wall is provided with a gap in the extending direction of the metal sleeve, and two sides of the gap are respectively provided with a notch and a protrusion which are matched with each other.
Preferably, the first side wall is provided with a through hole, and a spring plate is fixed on one side wall of the through hole far away from the inclined plane.
Preferably, the first side wall and the elastic sheet are integrally formed.
Preferably, one end of the inclined surface of the first side wall is provided with one or more supporting plates, and a plane defined by the end parts of the supporting plates and the end parts of the second side wall is perpendicular to the extending direction of the metal sleeve.
The technical scheme also provides a USB connector which comprises the USB metal shell.
The USB metal shell disclosed by the invention has the beneficial effects that: a rectangular metal sleeve formed by crimping. The metal sleeve comprises a first side wall and a second side wall which are opposite, the length of the first side wall is smaller than that of the second side wall, an inclined surface is formed, and an included angle is formed between the inclined surface and the extending direction of the metal sleeve. When a user holds the USB connector, the direction can be distinguished by touching the inclined plane formed by the end part of the first side wall and the end part of the second side wall by a finger. Therefore, a user can accurately insert the USB metal shell of the USB connector into the USB female seat without checking.
Drawings
FIG. 1 is a schematic diagram of a USB metal shell according to an embodiment of the invention.
Fig. 2 is a schematic structural diagram of a USB metal shell according to an embodiment of the present invention.
Detailed Description
The invention is further illustrated and described below in conjunction with the specific embodiments and the accompanying drawings:
example 1
Referring to fig. 1, a rectangular metal sleeve 10 is formed by crimping a USB metal case. The metal sleeve 10 includes a first side wall 11 and a second side wall 12 opposite to each other, the length of the first side wall 11 is smaller than that of the second side wall 12, and an inclined surface 13 is formed, and the inclined surface 13 forms an included angle with the extending direction of the metal sleeve 10.
When the user holds the USB connector, the direction can be distinguished by touching the inclined surface 13 formed by the end of the first side wall 11 and the end of the second side wall 12 with a finger. Therefore, a user can accurately insert the USB metal shell of the USB connector into the USB female seat without checking.
In this embodiment, the included angle ranges from 30 ° to 60 °, and the user can obviously feel the drop feeling while avoiding the first sidewall 11 from being too short in length to expose the subsequently inserted stitch.
The first side wall 11 and the second side wall 12 are provided with a plurality of fixing holes 14. The USB socket is used for being matched with a fixed elastic sheet arranged inside the USB socket to be fixed. In order to ensure the stability of insertion, the design that the first side wall 11 and the second side wall 12 are respectively provided with two fixing holes 14 is adopted in the embodiment, and the fixing holes 14 formed in the first side wall 11 and the fixing holes 14 formed in the second side wall 12 are symmetrically arranged.
The first side wall 11 is provided with a through hole 111, and a spring plate 112 is fixed on a side wall of the through hole 111 away from the inclined surface 13. When the USB metal shell of the USB connector is inserted into the USB female seat, the elastic sheet 112 can abut against a nonmetal area in the USB female seat, so that secondary fixation is realized.
The first side wall 11 and the elastic sheet 112 are integrally formed. Its elasticity can be enhanced.
The second side wall 12 is provided with a slit 121 along the extending direction of the metal sleeve 10, and two sides of the slit 121 are respectively provided with a notch 1211 and a protrusion 1212 which are matched with each other. For locking the crimp of the metal sleeve 10.
The end of the second side wall 12 away from the inclined surface 13 is provided with an extension plate 122, and a plurality of grooves 1221 are formed in the extension plate 122. When the stitch and the core wire are welded, the core wire can be clamped into the groove 1221 for fixed welding
The embodiment also provides a USB connector, including a USB metal case as described above.
Example two
Referring to fig. 2, in the present embodiment, one or more support plates 213 are provided at one end of the inclined surface 23 of the first sidewall 21 on the basis of the first embodiment. The plane defined by the end of the support plate 213 and the end of the second side wall 22 is perpendicular to the extending direction of the metal sleeve 20. While not affecting the touch, the first side wall 21 is propped against the bottom of the USB female seat through the supporting plate 213, so that the whole inclination caused by bottom contact of one side is avoided.
The invention provides a USB metal shell and a rectangular metal sleeve formed by crimping. The metal sleeve comprises a first side wall and a second side wall which are opposite, the length of the first side wall is smaller than that of the second side wall, an inclined surface is formed, and an included angle is formed between the inclined surface and the extending direction of the metal sleeve. When a user holds the USB connector, the direction can be distinguished by touching the inclined plane formed by the end part of the first side wall and the end part of the second side wall by a finger. Therefore, a user can accurately insert the USB metal shell of the USB connector into the USB female seat without checking.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
