Detailed Description

Referring to fig. 1-8, the present utility model provides an anti-unplugging USB connector, comprising a male component and a female component.

Referring to fig. 2 to 4, the male assembly described above includes a male metal shell 1 and a mating core 2, and an upper cover 3 and a lower cover 4 for forming a cavity for accommodating the male metal shell 1 and the core 2. The male head assembly is also internally provided with a male head anti-pulling assembly, and the male head anti-pulling assembly comprises a spring plate 6 arranged in an elongated slot at the top of the male head metal shell 1 and a one-way buckle 7 arranged at the free end of the spring plate 6 and forming a buckle structure with a limit hole 5-1 in a USB female port in host equipment. Wherein, the connecting end of the spring plate 6 is positioned in the cavity, and the unidirectional buckle 7 is positioned outside the cavity. By adopting the design of the unidirectional buckle 7, after the male component is inserted into the host device 5, the unidirectional buckle 7 enters the limiting hole 5-1 and is clamped with the limiting hole, and at the moment, the male component cannot be pulled out of the USB female port of the host device 5. The unidirectional buckle 7 is formed by outwards bending the end part of the elastic sheet 6 by 90 degrees, and the bent end part is inwards bent by a certain angle to form a guide part so as to be beneficial to entering the USB female port of the host equipment 5. In the present embodiment, after the male metal shell 1 and the core 2 are installed between the upper cover 3 and the lower cover 4, the upper cover 3 and the lower cover 4 are formed into an integrated structure by ultrasonic welding.

The threaded hole 3-1 is also provided with a plastic cap 9 for closing the threaded hole 3-1. The male component cannot be pulled out after being inserted into the host device 5, when the male component needs to be pulled out, the plastic cap 9 needs to be pulled out, then the screw 8 is screwed down so that the one-way buckle 7 is separated from the limiting hole, and the male component can be pulled out easily. When someone maliciously pulls out the male component, at first will get rid of plastic cap 9, plastic cap 9 will obviously warp after receiving external force to pick out, so can easily distinguish if someone illegally operates.

Referring to fig. 5-8, the female assembly described above includes a female housing 10, a standard USB female port 11 disposed within the female housing 10, and plugs 12 at both ends of the female housing 10. In this embodiment, in order to prevent the USB disk 21 or Ukey from being pulled out of the standard USB female port 11, a female port pulling-preventing component is provided between the female head housing 10 and the standard USB female port 11. The female port anti-pulling assembly comprises an anti-pulling sleeve 13 sleeved on the outer side of the standard USB female port 11, an anti-pulling elastic sheet 15 arranged on the anti-pulling sleeve 13 and positioned on the outer side of a positioning elastic sheet 14 of the standard USB female port 11, and an anti-pulling screw 16 in threaded connection with an anti-pulling hole 10-1 in the female head shell 10 and with an inner end surface positioned on the outer side of the anti-pulling elastic sheet 15. The end of the anti-pulling elastic sheet 15 is provided with a driving part 15-1 bent towards the groove at the end of the positioning elastic sheet 14. An anti-pulling cap 17 for closing the anti-pulling hole 10-1 is arranged in the anti-pulling hole 10-1. When the device with the standard USB male port is inserted into the standard USB female port 11, the positioning spring piece 14 can enter the notch of the standard USB male port so as to realize positioning. At this time, the anti-pulling screw 16 is screwed to drive the driving part 15-1 of the anti-pulling elastic sheet 15 to move downwards into the groove at the end of the positioning elastic sheet 14 so as to prevent the anti-pulling elastic sheet from lifting upwards, thereby realizing the anti-pulling effect; finally, the anti-pulling cap 17 is installed again. When someone maliciously pulls out the device with the standard USB male port, the anti-pulling cap 17 is removed first, and the anti-pulling cap 17 is obviously deformed after being picked out by external force, so that the device is easy to distinguish.

Referring to fig. 1-8, in the embodiment of the present utility model, one end of the male component is provided with a connecting wire, the other end of the connecting wire is provided with a special-shaped male port 18, a special-shaped female port 19 matched with the special-shaped male port 18 is provided in the female head housing 10, and a connecting plate 20 is provided between the special-shaped female port 19 and the standard USB female port 11. The cut-off surface of the shaped male opening 18 may be in the shape of a chamfer, square, etc., while the cut-off surface of the shaped female opening 19 is in the shape of a shape adapted to the shaped male opening 18. In addition, the connection can be realized by directly arranging a connecting wire between the male head component and the female head component.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same; while the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present utility model or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the utility model, it is intended to cover the scope of the utility model as claimed.
