The male plug 1 and the female plug 2 are provided with a plurality of corresponding wire holes 12, and wires 11 are arranged in the wire holes 12. The wires 11 are fixed in the wire holes 12 through terminals, and the terminals on the male plug 1 and the female plug 2 are connected to each other to achieve the connection of the wires 11 on both sides.

[0022] See also Figure 1 and Figure 2 In one embodiment, the male plug 1 includes an insertion end 13 and a top plate 16, and the insertion end 13 is used to be inserted into the embedding groove 221 of the female plug 2. In one embodiment, the wire hole 12 of the male plug 1 is located on the insertion end 13, and the top plate 16 is located at the end of the male plug 1 away from the embedding groove 221. The top plate 16 is used to abut against the opening of the embedding groove 221 of the female differential head to achieve fixation and position determination between the male plug 1 and the female plug 2.

[0023] In one embodiment, a shrapnel 14 is provided on the insertion end 13. The shrapnel 14 is located at both ends of the insertion end 13 in the length direction. The shrapnel 14 is L-shaped. The horizontal section of the shrapnel 14 is perpendicular to the side surface of the insertion end 13. The vertical section of the shrapnel 14 extends towards the end away from the female plug 2. An inlay block 141 is provided on the side of the vertical section of the shrapnel 14 away from the horizontal section. The end face of the inlay block 141 away from the female plug 2 is perpendicular to the horizontal section. The inlay block 141 is inclined towards the side pointing to the female plug 2, and its inclination direction points downward and outward. In one embodiment, the horizontal section of the shrapnel 14 extends towards the end away from the female plug 2 to form an extension part 142, and when the insertion end 13 is inserted into the embedding groove 221, it protrudes from the embedding groove 221. A pressing part 143 is provided on the protruding part of the extension part 142, and the pressing part 143 is located on the side of the extension part 142 away from the insertion end 13.

[0024] Please refer to Figure 1 and Figure 2 As shown in, a handle 15 is provided on the outside of the shrapnel 14. The handle 15 is U-shaped. The opening of the handle 15 points to the end away from the female plug 2. The bottom of the U-shape of the handle 15 is fixedly arranged with the side of the insertion end 13. The opening of the U-shape of the handle 15 extends towards the end away from the insertion end 13. And, the openings of the handle 15 are connected by a connecting rod 151, thus realizing the stability of the structure.

[0025] Please refer to Figure 1 and Figure 2 As shown in, in one embodiment, the female plug 2 includes a base 21 and an insertion part 22. The insertion part 22 is for the insertion of the insertion end 13. The embedding groove 221 is provided on the insertion part 22;

[0026] A through hole 222 is provided on the outer side wall of the insertion part 22. The through hole 222 is arranged to match the inlay block 141. Through the matching arrangement of the through hole 222 and the inlay block 141, the male plug 1 and the female plug 2 can be stably fixed. In one embodiment, the dimension of the through hole 222 in the direction pointing to the male plug 1 is larger than the dimension of the inlay block 141 in this direction; secondly, through the setting of the pressing part 143, pressing the extension part 142 makes the inlay block 141 slide inwards out of the through hole 222, so that the insertion end 13 can be conveniently disassembled.

[0027] In one embodiment, in order to facilitate the holding of the female plug 2, a plurality of protruding parts 223 are provided on the outer circumference of the insertion part 22 on two opposite sides. The protruding parts 223 are strip-shaped and are arranged in an array along the direction of the insertion part 22 pointing to the male plug 1.

[0028] Please refer to Figure 1and Figure 2 , three protrusions 223 are respectively provided on both sides; in other embodiments, the number of the protrusions 223 can be increased or decreased according to requirements.

[0029] Working principle:

[0030] During the installation process, by inserting the insertion end 13 into the insertion slot, at this time, the insert block 141 slides inward under the action of the inclined surface. When the insert block 141 reaches the position of the through hole 222, the insert block 141 pops out outward and is fixed in the through hole 222. After the insertion is completed, the position fixation between the male plug 1 and the female plug 2 is achieved through the setting of the top plate 16.

[0031] For an electric vehicle line-to-line connector provided by the present application, through the mutual matching setting between the insert block 141 on the elastic piece 14 and the through groove, during use, the relative stability between the male plug 1 and the female plug 2 can be ensured. At the same time, through the setting of the elastic piece 14, the male plug 1 and the female plug 2 can be conveniently disassembled.
