When the conductive terminal 2 is assembled in the holding terminal 3, the conductive terminal 2 is inserted into the receiving space 30, the first resilient piece 221 and the third resilient piece 222 pass through the first channel 333, and the first fixing block 331 and the second fixing block 332 are both pressed against the first fixing portion 21; meanwhile, the second elastic sheet 241 and the fourth elastic sheet 242 pass through the second channel 343, and the third fixed block 341 and the fourth fixed block 342 are both pressed against the second fixing portion 23. When the conductive terminal 2 is mounted in place, the first butt-joint portion 22 and the second butt-joint portion 24 penetrate through the receiving space 30, the first latch arm 311 and the second latch arm 321 are respectively clamped in the upper latch groove and the lower latch groove, and the first limiting protrusion 213 and the second limiting protrusion 214 are used for abutting against the first side wall 31 and the second side wall 32 to prevent the conductive terminal 2 from being excessively mounted in the holding terminal 3.

Referring to fig. 19 and 20, after the connector is mounted, the first fixing portion 21 and the third sidewall 33 are adjacent to each other and spaced apart from each other, and the electrical connector 100 includes a first heat dissipation channel 401 located between the first fixing portion 21 and the third sidewall 33; the second fixing portion 23 is adjacent to and spaced apart from the fourth sidewall 34, and the electrical connector 100 includes a second heat dissipation channel 402 between the second fixing portion 23 and the fourth sidewall 34. The first heat dissipation channel 401 and the second heat dissipation channel 402 are used for allowing air to circulate, so that heat generated during power transmission can be dissipated, and safety is improved.

Referring to fig. 14 to 17, when the conductive terminal 2 is butted with the butted conductive terminal 8, the first butting portion 22 and the second butting portion 24 of the conductive terminal 2 are at least partially inserted into the butting cavity 810, and two ends (for example, upper and lower ends) of the first butting portion 22 and the second butting portion 24 are respectively attached to the first connecting wall 813 and the second connecting wall 814. That is, the first and second connection walls 813 and 814 function to position the first and second docking portions 22 and 24. When the conductive terminal 2 is inserted in place, the first abutting convex strip 8111 abuts against the portions of the first abutting portion 22 located at the two sides of the first elastic sheet 221 and the third elastic sheet 222, the second abutting convex strip 8121 abuts against the portions of the second abutting portion 24 located at the two sides of the second elastic sheet 241 and the fourth elastic sheet 242, the first elastic sheet 221 and the third elastic sheet 222 abut against the inner side of the first contact wall 811, and the second elastic sheet 241 and the fourth elastic sheet 242 abut against the inner side of the second contact wall 812. With such an arrangement, the first docking portion 22 and the second docking portion 24 are accurately positioned in four directions, namely, up, down, left and right, so that the shaking possibly generated when the conductive terminals 2 and the docking conductive terminals 8 are docked is reduced, and the docking reliability is improved.

Compared with the prior art, the first mating portion 22 of the present invention is provided with the first elastic sheet 221, and the first elastic sheet 221 includes the first elastic contact portion 2211 protruding from the first fixing portion 21 along the first direction A1-A1; the second abutting portion 24 is provided with a second elastic piece 241, and the second elastic piece 241 includes a second elastic contact portion 2411 protruding from the second fixing portion 23 along the first direction A1-A1; the first elastic contact portion 2211 extends along a first arc-shaped surface, the second elastic contact portion 2411 extends along a second arc-shaped surface, and the protruding direction of the first arc-shaped surface is opposite to the protruding direction of the second arc-shaped surface along the first direction A1-A1; therefore, the elastic contact part is arranged on the butt joint part, the switching reed is omitted, and the structural reliability and the safety are improved.
