[0022] Example:

[0023] See also Figures 1-6 The utility model provides a technical solution: a power cord plug protection assembly, including a wire 2, a socket male connector 1 is provided at the front end of the wire 2, the socket male connector 1 includes a fixed shell 101, a heat dissipation ring 102 is fixedly connected to the front end of the fixed shell 101, the heat dissipation ring 102 is fixedly connected to the end of the fixed shell 101 away from the fixed shell 101, the male connector fixing plate 103 is fixedly connected to the front side wall of the male connector fixing plate 103, the plug body 104 is fixedly connected to the front side wall of the plug body 104, a circular groove 105 is opened on the front side wall of the circular groove 105, and a contact 107 is fixedly connected to the inner wall of the circular groove 105. A protective component is provided on the outside of the contact 107, and a protective sleeve 4 is provided on the rear side wall of the male connector fixing plate 103. The protective sleeve 4 is sleeved on the outside of the heat dissipation ring 102. When the male connector 1 is not connected to an electronic device, the protective sleeve 4 covers the outside of the heat dissipation ring 102 and the plug body 104 to protect the male connector 1 from damage caused by external forces. The front end of the plug body 104 protects the contact 107 through the protective component, thereby preventing the contact 107 from getting damp or dusty, thereby improving the stability of the power line signal transmission;

[0024] The protective assembly includes a protective plate 106, which is slidably connected to the circular groove 105. A circular hole is opened on the protective plate 106, and a rubber sleeve 108 is provided on the outer wall of the contact 107. The front end of the rubber sleeve 108 passes through the circular hole and extends to the outside of the protective plate 106. The rubber sleeve 108 is sleeved on the outside of the contact 107 to prevent the contact 107 from getting damp or dusty. After the rubber sleeve 108 is sleeved, the protective plate 106 is slid into the inside of the circular groove 105, and the flange at the tail of the rubber sleeve 108 is pressed to prevent the rubber sleeve 108 from loosening and falling off. When the male socket 1 is plugged into the electronic device, the rubber sleeve 108 is squeezed and contracted, causing the contact 107 to leak out, thereby realizing the plugging function;

[0025] The protective sleeve 4 includes a sleeve body 401, the inner wall of the sleeve body 401 is fixedly connected to a spring 402, and one end of the spring 402 away from the sleeve body 401 is fixedly connected to the outer wall of the male head fixing plate 103, the front end of the sleeve body 401 is fixedly connected to a ring 403, and the front side wall of the ring 403 is bonded with a rubber pad 404. When the male socket 1 is plugged into the electronic device, the ring 403 is squeezed, pushing the sleeve body 401 to move backward, so that the circular opening at the rear end of the sleeve body 401 moves to the outside of the wire 2, and because the diameter of the fixed shell 101 is larger than the diameter of the wire 2, a gap will be left between the circular opening at the rear end of the sleeve body 401 and the wire 2, and the gap is used to achieve ventilation and heat dissipation, thereby preventing the connection end of the male socket 1 from overheating, and the spring 402 plays a pulling role, so that the ring 403 can always abut against the outer wall of the electronic device, thereby preventing the male socket 1 from having a gap at the connection between the electronic device and the electronic device, thereby preventing moisture or dust from entering, and further improving the stability of power line signal transmission;

[0026] A socket female 3 is provided at the rear end of the wire 2, and the socket female 3 includes a female fixing plate 301, the inner wall of the female fixing plate 301 is fixedly connected to the female plug 302, and the rear side wall of the female fixing plate 301 is fixedly connected to a fixing ring 303, the fixing ring 303 is located on the outside of the female plug 302, the outer wall of the fixing ring 303 is hinged with a sealing cover 304, and the inner wall of the sealing cover 304 is fixedly connected to a sealing ring 305. The sealing cover 304 is used to protect the socket female 3 from dust and moisture. A sealing ring 305 is provided on the inner side of the sealing cover 304, and the end of the sealing ring 305 protrudes outward, and the protrusion is elastic. When it cooperates with the recessed part of the fixing ring 303, it can be fully squeezed and pressed tightly, thereby enhancing the protective effect of the sealing cover 304 on the female plug 302.

[0027] Working principle: When the male socket 1 is not connected to an electronic device, the protective cover 4 covers the outside of the heat dissipation ring 102 and the plug body 104 to protect the male socket 1 and prevent the male socket 1 from being damaged by external forces. The front end of the plug body 104 protects the contact 107 through the protective component, thereby preventing the contact 107 from getting damp or getting dusty, thereby improving the stability of signal transmission. The rubber cover 108 is put on the outside of the contact 107 to prevent the contact 107 from getting damp or getting dusty. After the rubber cover 108 is put on, the protective plate 106 is slid and embedded into the inside of the circular groove 105, and the flange at the tail of the rubber cover 108 is pressed to prevent the rubber cover 108 from loosening and falling off. When the male socket 1 is plugged into an electronic device, the rubber cover 108 is pressed tightly to prevent the rubber cover 108 from loosening and falling off. The rubber sleeve 108 is squeezed and contracted, causing the contact 107 to leak out, thereby realizing the plug-in function. When the ring 403 is squeezed, it pushes the sleeve 401 to move backward, causing the circular opening at the rear end of the sleeve 401 to move to the outside of the wire 2. Since the diameter of the fixed shell 101 is larger than the diameter of the wire 2, a gap will be left between the circular opening at the rear end of the sleeve 401 and the wire 2. Through this gap, ventilation and heat dissipation effects are achieved to prevent the connection end of the socket male head 1 from overheating, and the spring 402 plays a pulling role, so that the ring 403 can always abut against the outer wall of the electronic device, avoiding the appearance of a gap at the connection between the socket male head 1 and the electronic device, which may cause moisture or dust to enter, further improving the stability of power line signal transmission.
