[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Figures 1 to 4The USB connecting line comprises a first connector 10 and a second connector 50. The first connector 10 is provided with a pulling end 101 at one end thereof. The first connector 10 is fixedly connected with the second connector 50 through a connecting line 60 at a middle position of the first connector 10. The first connector 10 is provided with a first plug-in interface 20 at the other end thereof. The second connector 50 is provided with a second plug-in interface 55 at one end thereof. The first plug-in interface 20 is provided with an inclined shell 21 at one end thereof. The inclined shell 21 is preferably made of plastic. The inclined shell 21 is provided with a female seat 30 at the bottom end thereof. The female seat 30 is provided with a first power gold finger 40 and a data gold finger 45 at one end thereof. The second plug-in interface 55 is provided with a plug hole 56. The plug hole 56 is provided with a pressing groove 59 close to the second connector 50.

[0024] The female seat 30 is further provided with a strip-shaped groove 31 at one end thereof. The female seat 30 is provided with a first vertical rib 42 and a second vertical rib 43 at the other end thereof. The first power gold finger 40 and the data gold finger 45 are arranged on the upper side of the strip-shaped groove 31. In order to improve the reliability of the contact, the female seat 30 is provided with a plurality of first elastic sheets 41 arranged on both sides of the first power gold finger 40 or the data gold finger 45. The output voltage of the first power gold finger 40 is 4.75V-5.25V, which is suitable for the PCB interface. The pulling end 101 comprises two U-shaped grooves 12 and a convex column 11. The U-shaped grooves 12 are arranged on both sides of the center line of the first connector 10. The convex column 11 is arranged at one end of the first connector 10. The U-shaped groove 12 is provided with a circular arc corner 121, which is beneficial to automatic clamping and prevents scratching.

[0025] The first connector 10 and the connecting line 60 are provided with a crimping ring 15, which is an integral structure with the first connector 10. The first connector 10 is provided with a reinforcing rib 16 at each of the two sides in the length direction, which improves the connection strength of the end of the connecting line 60. The connecting line 60 is a 4-core wire, which is beneficial to the transmission of power and data.
