Specific embodiment

Technical solutions of the utility model are further described below by embodiment:

The utility model provides a kind of Novel pin of USB charging plug, as shown in Figure 1, pin includes: 1 He of insulating part Conduct piece 2, insulating part 1 are fixed on the rear end of conduct piece 2.When pin is installed into the shell of USB charging plug, insulating part 1 It is fixed in the shell of USB charging plug, the front end of conduct piece 2 extends to the outside of the shell of USB charging plug, conduct piece 2 For being electrically connected with the formation of the conductive sheet of socket.

As shown in Fig. 2, insulating part 1 includes: main body 11, sheath 12 and isolation board 13, main body 11 and sheath 12 are all hollow Body, sheath 12 are located at from the rear end of main body 11 protrusion, isolation board 13 close to main body 11 from the front end of main body 11 protrusion, isolation board 13 The position of inside.The outside of main body 11 has rectangular recess 14, a rectangle of rectangular recess 14 and the shell of USB charging plug Column engagement, to prevent pin relative to the swing or rotation of above-mentioned shell generation up and down direction.The top and bottom of main body 11 are all Raised bolt 15, bolt 15 are engaged with the pin hole of above-mentioned shell, so that it is left to prevent the relatively above-mentioned shell of pin from occurring The swing or rotation of right direction.

As shown in figure 3, conduct piece 2 includes: plugboard 21 and electrode 22, electrode 22 is inserted from the rear end of plugboard 21 protrusion The front end of fishplate bar 21 has spliced eye 23.Main body 11 and sheath 12 all surround the rear end of plugboard 21, isolation board 13 and electrode 22 Alignment.Wherein, main body 11 is located at the inside of the shell of USB charging plug, for fixing conduct piece 2；Sheath 12 is located at USB charging The outside of the shell of plug, sheath 12 can play a protective role to user；Isolation board 13 can reduce to be sent out between two pins A possibility that raw short circuit, to be effectively protected USB charging plug.

Specifically, the width (size in left-right direction) of main body 11 is greater than the width of plugboard 21, the height of main body 11 (size along the vertical direction) is greater than the height of plugboard 21.To make insulating part 1 play position-limiting action, pin is prevented to be inserted into Too deep position.

Specifically, insulating part 1 is formed by plastic material, and conduct piece 2 is formed by copper product.Insulating part 1 can be by mould The mode of injection molding is formed in the rear end of conduct piece 2, simplifies manufacturing process, improves efficiency.

More specifically, the rear end of plugboard 21 has multiple locating slots 24, multiple locating slots 24 are after plugboard 21 Hold evenly distributed, the inside of main body 11 has multiple positioning bars, and multiple positioning bars are evenly distributed around the inside of main body 11, positioning Muscle is inserted into locating slot 24.By the cooperation of positioning bar and locating slot 24, it can prevent 2 opposing insulation part 1 of conduct piece from revolving Turn, it is user-friendly.Wherein, positioning bar synchronizes to be formed when carrying out the in-mould injection of insulating part 1.

Specifically, in the present embodiment, rectangular recess 14 is square, and the length and height of rectangular recess 14 are all 2- 3mm.Bolt 15 is cylindrical body, and the height of bolt 15 is 0.6-0.9mm, radius 0.8-1.0mm.

As it can be seen that the Novel pin of the USB charging plug with above structure, it not only can be to avoid random in use It swings or rotates, it is user-friendly, and also conduct piece is independently arranged, and can be effectively reduced between two conduct pieces and short circuit occurs Possibility.
