At the same time, the block is squeezed by the block to drive the sleeve rod to move in the direction of the limit plate, and the spring is squeezed and elastically deformed. When the notch on the block is clamped on the annular groove, the spring is reset to clamp and fix the block. At the same time, the conductor on one end of the wire is always plugged into the conductive copper sleeve to prevent the terminal seat from being virtual connection with the wire.

[0020] 2. The power terminal block is constructed by removing the cover plate from the connection groove and applying tension to the limit plate sleeved on the sleeve rod. At this time, the limit plate drives the sleeve rod to move in the inner cavity of the limit cylinder and move away from the block. Then the wire is removed from the terminal seat. At this time, the conductor on one end of the wire is detached from the inner cavity of the conductive copper sleeve. During this period, the spring undergoes elastic deformation in the inner cavity of the limit cylinder, thereby facilitating the rapid removal of the wire, and the operation is simple and quick.

[0028] The terminal seat 1 is provided with an anti-loosening structure 14 , and the anti-loosening structure 14 is movably connected to the stopper 3 .

[0029] A connecting groove 11 is provided inside the terminal seat 1, and the inner cavity diameter at one end of the connecting groove 11 is larger than the inner cavity diameter at the other end. A conductive copper sleeve 12 is fixedly installed on the small-diameter inner cavity wall of the connecting groove 11, and the inner cavity of the conductive copper sleeve 12 is electrically connected to the conductor on the wire 2.

[0030] The large diameter inner cavity wall of the connecting groove 11 is movably connected with the cover plate 4 . A fixing hole 13 is provided on the large diameter inner cavity wall of the connecting groove 11 . The inner cavity wall of the fixing hole 13 is fixedly connected with the anti-loosening structure 14 .

[0031] The diameter and size of the large-diameter inner cavity of the connecting groove 11 are matched with the diameter and size of the outer surface of the cover plate 4 .

[0032] The anti-loosening structure 14 includes a limiting cylinder 141, the outer surface of the limiting cylinder 141 is fixedly connected to the inner cavity of the fixing hole 13, a sleeve rod 142 is movably sleeved inside the limiting cylinder 141, a spring 144 is sleeved on the outer surface of the sleeve rod 142, one end of the spring 144 is fixedly connected to the inner cavity wall of the limiting cylinder 141, and the spring 144 is in an extended state;

[0033] A clamping block 145 is fixedly mounted on one end of the sleeve rod 142, and the clamping block 145 is movably connected to the stopper 3. A limiting plate 143 is fixedly sleeved on the outer surface of one end of the sleeve rod 142 away from the stopper 3, and the limiting plate 143 is movably connected to one end of the limiting tube 141.

[0034] A side surface of the clamping block 145 away from the sleeve rod 142 is in the form of an inclined surface 1451 , and a notch 1452 is formed inside the bottom end. The inclined surface 1451 , the notch 1452 and the stopper 3 are all movably connected.

[0035] The outer surface of one end of the stopper 3 is in the form of an arc surface 31 , and the arc surface 31 is movably connected to the inclined surface 1451 .

[0036] An annular groove 32 is formed on the outer surface of the other end of the stopper 3 , and the inner cavity of the annular groove 32 is movably connected to the notch 1452 .

[0037] Working principle: by plugging and assembling the wire 2 onto the terminal seat 1, at this time, the conductor on one end of the wire 2 is plugged into the inner cavity of the conductive copper sleeve 12, and the wire 2 drives the stopper 3 to be clamped in the inner cavity of the connecting groove 11. During this period, the arc surface 31 on the stopper 3 contacts the inclined surface 1451 and moves in a close fit until the notch 1452 on the clamping block 145 contacts the annular groove 32 and is clamped.

[0038] When it is necessary to quickly remove the wire 2, the cover plate 4 is removed from the connecting groove 11, and then a pulling force is applied to the limit plate 143 sleeved on the sleeve rod 142. At this time, the limit plate 143 drives the sleeve rod 142 to move in the inner cavity of the limit cylinder 141 and moves away from the block 3. Then the wire 2 is removed from the terminal seat 1. At this time, the conductor on one end of the wire 2 is detached from the inner cavity of the conductive copper sleeve 12. During this period, the spring 144 undergoes elastic deformation in the inner cavity of the limit cylinder 141, thereby facilitating the rapid removal of the wire 2, and the operation is simple and quick. The device can not only prevent loosening between the terminal and the wire 2, but also facilitate rapid removal, and the operation is simple and quick.
