Referring to fig. 3 and 4, when the terminal 300 needs to be inserted between the first and second inserts 100 and 200 or the terminal 300 needs to be removed from between the first and second inserts 100 and 200, the terminal 300 is removed by rotating the first insert 100 to separate the first end 110 from the second end 210. When the terminal 300 needs to be fastened, the terminal 300 is clamped by the first end portion 110 and the second end portion 210 together only by rotating the first insert 100, the operation steps are convenient and fast, and the work efficiency can be greatly improved.

Referring to fig. 2, it should be noted that when the first end portion 110 is located at the first position 111, the cavity 130 is in communication with the outside, that is, the cavity 130 has an opening 131. Therefore, one end of the terminal 300 can be accommodated in the cavity 130, and the other end of the terminal can penetrate out of the cavity 130 through the opening 131, so as to fasten the terminal 300.

It is understood that the first end portion 110 and the second end portion 210 can clamp the terminal 300 to be fastened, and a groove can be further provided on the first end portion 110 and the second end portion 210, thereby achieving more stable fixation of the terminal 300. The recess may be provided in the first insert 100 or the second insert 200. Referring to fig. 3 to 6, grooves may be simultaneously formed on the first insert 100 and the second insert 200.

In some embodiments, a continuous force is required to force the first end 110 toward the second end 210 to clamp the terminal 300 that has penetrated into the first and second inserts 100, 200.

It should be noted that the elastic member 500 is selected according to the actual situation. The elastic member 500 is respectively connected to the first insert 100 and the second insert 200, and the elastic member 500 can generate an elastic force that makes the first end portion 110 close to or away from the second end portion 210, that is, after the terminal 300 is inserted into the cavity 130, the first end portion 110 is close to the second end portion 210 so as to jointly clamp the terminal 300, thereby achieving the fastening of the terminal 300, and this fastening structure is convenient and fast to operate.

In some embodiments, the elastic member 500 may be disposed at different positions according to the specific structure of the insert to generate an elastic force to continuously fix the terminal 300. The elastic member 500 may be disposed between the first end portion 110 and the second end portion 210, and both ends of the elastic member 500 are connected to the first end portion 110 and the second end portion 210, respectively, and the first end portion 110 is moved toward the second end portion 210 by the pulling force of the elastic member 500 itself, thereby fastening the terminal 300 between the first end portion 110 and the second end portion 210. When the terminal 300 needs to be released and demolded, the terminal 300 may be pulled out by pressing one end of the first insert 100 away from the first end 110 with an external force.

Alternatively, a torsion spring may be installed at the rotational connection position, and the torsion force of the torsion spring itself is used to make the first end portion 110 approach the second end portion 210, so as to fix the terminal 300. When the terminal 300 needs to be removed, the terminal 300 clamped between the first insert 100 and the second insert 200 is removed by pressing the end of the first insert 100 away from the end acted by the torsion spring to make the first end 110 away from the second end 210.

The second connection face 244 includes a flat surface 245 and a beveled surface 246. A ramp 246 is provided at the end facing away from the chamber 130 based on the rotational connection, and a flat 245 is connected to the ramp 246. When the first end 110 is in the first position 111, the distance between the inclined surface 246 and the first connecting surface 143 increases in a direction from the rotational connection to the second end 210. The increasing distance refers to a gap between the inclined surface 246 and the first connection surface 143 when the first end portion 110 abuts against the second end portion 210, and the gap can provide a redundant space for the first end portion 110 to move away from the second end portion 210, thereby serving as a space-avoiding function.

It will be appreciated that when the first end portion 110 is in the second position 112, the sloped surface 246 and the first connection surface 143 abut, and the spacing between the flat surface 245 and the first connection surface 143 increases in a direction from the pivot connection to the second end portion 210. The ramp 246 provides for the avoidance of the first insert 100 during rotation to the second position 112.
