[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] A USB connector female head, such as Figure 2 As shown, it includes a terminal head 1, the end of the terminal head 1 is fixedly connected to a connector shell 2, a connector inner shell 3 is fixedly installed inside the connector shell 2, an auxiliary fixing button 4 is rotatably connected to the top of the connector inner shell 3, and a connector 5 is fixedly connected to the inside of the connector inner shell 3.

[0029] The connection of the line is achieved through the wiring head 1, and the connector housing 2 is used to assist the user in holding the connector to avoid the problem of inconvenience caused by the user's hand slipping, and the auxiliary fixing button 4 is used to control the fixation of the USB male and female connectors.

[0030] like Figure 3 As shown, one end of the terminal head 1 away from the terminal housing 2 is fixedly connected with a connecting wire 11 .

[0031] An anti-slip groove 21 is formed on the outer side of the joint housing 2 , and a connection socket 22 is formed on one end of the joint housing 2 away from the wiring head 1 .

[0032] The circuit is connected through the connecting wire 11 at the rear end of the terminal head 1, and the anti-skid groove 21 on the outer side of the connector shell 2 is used to assist the user and prevent the problem of inconvenience caused by hand slipping.

[0033] like Figure 4 As shown, a side fixing plate 31 is provided on the outer side of the connector inner shell 3, fixing grooves 32 are provided on the top and bottom ends of the connector inner shell 3, a connecting fixing plate 33 is fixedly connected to the inner side of the fixing groove 32, and an auxiliary locking plate 34 is fixedly connected to the end of the connecting fixing plate 33 away from the terminal head 1.

[0034] The side fixing plate 31 at the side end of the connector inner shell 3 and the auxiliary locking plate 34 inside are used to assist in fixing the male connector and the female connector to prevent loosening and thus causing failure of the USB connection.

[0035] like Figure 1 and 5 As shown, the end of the auxiliary fixing button 4 close to the joint inner shell 3 is fixedly connected to a button connecting rod 41, the end of the button connecting rod 41 away from the auxiliary fixing button 4 is fixedly connected to an auxiliary locking rod 42, the end of the auxiliary locking rod 42 close to the connector 5 is fixedly connected to a connecting pressure rod 43, the end of the connecting pressure rod 43 close to the connector 5 is fixedly connected to a guide support plate 44, and the end of the guide support plate 44 close to the auxiliary fixing button 4 is fixedly connected to a locking pressure plate 45.

[0036] By controlling the angle of the button connecting rod 41 through the auxiliary fixing button 4, the connecting pressure rod 43 at the bottom end of the auxiliary locking rod 42 controls the guide support plate 44 and the locking pressure plate 45, so that the guide support plate 44 and the locking pressure plate 45 can control and lock the plug plate of the entering male connector, and the plug plate is further fixed under the control of the locking pressure plate 45 and the guide support plate 44, so that the auxiliary fixing hole at the bottom end of the male connector and the auxiliary locking plate 34 inside the bottom fixing groove 32 are fixed to each other to prevent loosening due to slight bumps and impacts, resulting in problems of line connection and disconnection.

[0037] like Figure 6 As shown, a plurality of contact accommodating openings 51 are provided inside the connector 5 , a pin bracket 52 is fixedly connected inside the contact accommodating opening 51 , and a transmission pin 53 is fixedly connected to one end of the pin bracket 52 away from the connector 5 .

[0038] The transmission pin 53 at the top of the pin bracket 52 contacts the signal transmission head inside the male connector, so that the signal between the two is connected, thereby realizing the signal transmission function of the USB.

[0039] When in use, first follow the normal usage method. The user holds the anti-slip groove 21 on the outside of the connector shell 2 with one hand to prevent sliding, and holds the USB male head to be installed with the other hand to plug the USB male head and the female head into each other. During this process, the hole on the outside of the male head and the side fixing plate 31 and the auxiliary locking plate 34 inside the connector inner shell 3 cooperate with each other to plug and fix, so that the male head and the female head can be installed with each other. During the installation process, the outer shell of the male head and the guide support plate 44 and the locking pressure plate 45 at the bottom of the auxiliary fixing button 4 are in contact with each other. The locking pressure plate 45 is used to push the outer shell of the male head to make it more closely contact with the auxiliary locking plate 34 at the bottom, thereby achieving more effective locking.

[0040] During the locking process, since the guide support plate 44 at the bottom of the auxiliary fixing button 4 is pressed by the outer shell of the male head, the auxiliary fixing button 4 will contact the inside of the outer shell of the connecting socket 22, so that the guide support plate 44 and the locking pressure plate 45 are locked with the outer shell of the male head. When unlocking is required, the auxiliary fixing button 4 is pressed manually to cause deformation inside the connecting socket 22, providing space for the movement of the auxiliary fixing button 4, thereby allowing the male and female heads to be unlocked.

[0041] When unlocking is required, the auxiliary fixing button 4 needs to be pressed to flip the auxiliary fixing button 4 toward the bottom, so that the guide support plate 44 and the locking pressure plate 45 move toward the rear end and flip toward the top, so that the outer shell of the male head is no longer locked in contact with the auxiliary locking plate 34, allowing the user to easily pull the male head out of the female head.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
