[0023] In this embodiment, the buckle 210 and the handlebar 211 are made of insulating materials, and the handlebar 211 is arranged perpendicular to the penetration direction of the bolt sleeve hole 212 .

[0024] Specifically, the insulating buckle ring 210 is used to control the unlocking and locking operations of the threaded ring 220 and the electrode threaded rod 111, thereby improving safety performance.

[0025] In this embodiment, the center of the eccentric sleeve hole 213 deviates from the center of the buckle 210 , and the outer periphery of the eccentric pressure edge 221 is in sliding contact with the inner side of the eccentric sleeve hole 213 .

[0026] Specifically, during the deflection movement of the retaining ring 210 , the threaded ring 220 is blocked by the electrode threaded rod 111 and remains stationary, so that the threaded ring 220 is engaged with the surface of the electrode threaded rod 111 by utilizing the contact between the eccentric sleeve hole 213 and the eccentric pressure edge 221 .

[0027] In this embodiment, the two-lobed structure of the threaded ring 220 is semi-cylindrical and a spring 240 is provided on the inner side thereof. The spring 240 is arranged perpendicular to the radial direction of the eccentric sleeve hole 213 .

[0028] Specifically, the spring 240 is used to realize the fast unlocking and resetting of the threaded ring 220 and the disengagement from the electrode threaded rod 111 .

[0029] In this embodiment, the wire clamping seat 230 is a metal spring structure, the wire clamping seat 230 is V-shaped and both ends are fixedly connected to the surface of the threaded ring 220 respectively, and a plurality of wire clamping grooves of different sizes are provided on the inner side of the wire clamping seat 230.

[0030] Specifically, the wire clamping seat 230 follows the locking of the threaded ring 220 to perform deformation movement to clamp the wire harness end.

[0031] The working principle and use process of this utility model:

[0032] When using the series reactor, a suitable wiring method can be selected according to the structure of the power connection terminal. The wire harness terminal has fasteners such as copper bars or copper rings, which can be directly sleeved on the surface of the electrode threaded rod 111, and the threaded ring 220 and the buckle ring 210 are synchronously sleeved on the surface of the electrode threaded rod 111. The handle bar 211 is pressed down to deflect the buckle ring 210. Under the action of the eccentric sleeve hole 213 and the eccentric pressure edge 221, the threaded ring 220 is squeezed during the deflection of the buckle ring 210, so that the threaded ring 220 is relatively fitted and connected to the electrode threaded rod 111, so as to realize the combination of the threaded ring 220 and the power connection terminal 110. The buckle ring 210 can be rotated to tighten the thread of the threaded ring 220 to press the end copper bar.

[0033] When connecting the wire harness end, the wire harness end is inserted into the inner side of the wire clamp seat 230, and the handle bar 211 is pressed down to cause the buckle 210 to deflect. Under the action of the eccentric sleeve hole 213 and the eccentric pressure edge 221, the buckle 210 deflects to squeeze the threaded ring 220, and the wire clamp seat 230 deforms synchronously to clamp and fix the wire harness end.
