Specifically, the movable portion 22 having elasticity may be provided with three pieces, with one end thereof being mounted on one end of the fixed portion 21 and disposed along the circumferential direction of the fixed portion 21. In order to press-contact the terminal having a smaller wire diameter, the terminal is inserted into the fixing sleeve first, and then the fixing sleeve 20 is inserted into the mounting through hole 11. It should be noted that, when the one end of the movable portion 22 is inserted into the mounting through hole 11, and then the first clamping block 12 in the mounting through hole 11 abuts against the guiding portion 221 outside the movable portion 22, so as to squeeze the movable portion 22, and further squeeze the three movable portions 22 inwards, so that the diameter of the one end of the movable portion 22 becomes smaller, and further the whole movable portion 22 passes through the first clamping block 12, after the guiding portion 221 of the movable portion 22 completely passes through the first clamping block 12, the accommodating groove at the rear side of the guiding portion 221 can clamp the first clamping block 12, and the movable portion 22 elastically returns to the original diameter due to itself, so that the whole fixing sleeve 20 is clamped in the mounting through hole 11, and further the terminal with smaller size is fixed, so that the terminal can be applied to the connector.

Further, in some embodiments of the present utility model, the terminal includes a first terminal 31, i.e. a smaller-sized terminal, in order to make the first terminal 31 stably fixed in the fixed sleeve 20, a plurality of elastic pieces 311 are provided at the front end of the first terminal 31, three elastic pieces 311 are shown in fig. 2, the elastic pieces 311 are distributed along the circumference of the first terminal 31, meanwhile, one end of each elastic piece 311 is connected to the first terminal 31, the other end of each elastic piece 311 extends outwards, a limiting block 222 is provided at the inner side of the movable portion 22, so that the movable end of each elastic piece 311 can abut against one end of the limiting block 222, and further one end of each limiting block 222 can be used to clamp the first terminal 31, so as to prevent the terminal from moving backwards.

Specifically, when one end of the first terminal 31 is inserted into the fixed sleeve 20, the stopper 222 on the inner side of the movable portion 22 abuts against the elastic piece 311, so that the elastic piece 311 is pressed, the elastic piece 311 is folded on the outer side of the terminal, when the elastic piece 311 on the front end of the first terminal 31 completely passes through the stopper 222, the elastic piece 311 is immediately released, and the movable end immediately pops onto the front end of the stopper 222, so that the first terminal 31 can be blocked by one end of the stopper 222, and the terminal can be prevented from moving back.

As can be seen from the above embodiment, when the elastic piece 311 at the front end of the first terminal 31 completely passes through the limiting block 222, the elastic piece 311 is released immediately, and the movable end immediately springs onto one end of the limiting block 222, so that the first terminal 31 is prevented from moving back by the first terminal 31 being blocked by one end of the limiting block 222, and the end of the first protrusion 312 can abut against the rear end of the limiting block 222, so that the first terminal 31 can be prevented from being inserted over the head, and the first terminal 31 can be well fixed by the fixing sleeve 20 in cooperation with the abutting of the elastic piece 311, so as to prevent the first terminal 31 from moving back and forth.

Referring to fig. 6 to 8, in some embodiments of the present utility model, the terminals include a second terminal 32, i.e., a terminal having a larger wire diameter, which can be directly crimped onto the mounting through hole 11. An elastic portion 321 is sleeved outside the second terminal 32, one end of the elastic portion 321 is provided with a guiding inclined plane 3211, and the other end of the elastic portion 321 can be abutted against one end of the first clamping block 12.

Specifically, when the front end of the second terminal 32 is inserted into the mounting through hole 11, the first clamping block 12 in the mounting through hole 11 can be abutted against the guide inclined surface 3211 of the elastic portion 321 sleeved outside the second terminal 32, and as the first clamping block 12 is continuously inserted, the elastic portion 321 is extruded along the guide inclined surface 3211 to reduce the diameter of the elastic portion 321, so that the elastic portion 321 passes through the first clamping block 12; when the elastic portion 321 passes through the first clamping block 12, the elastic portion 321 can be restored, and the rear end of the elastic portion can prop against the front end of the first clamping block 12, so that the second terminal 32 can be prevented from moving back to be unfavorable for connection of the connector.

It should be noted that, the elastic portion 321 may be a plastic member with elasticity, or may be a metal collar with an opening and elasticity, the diameter of the collar being extruded is reduced, and the opening is convenient for the collar to be reduced.
