[0024] like Figures 1-5 As shown: A locking structure includes: a mounting base 10, with cable placement slots 13 on both the front and rear sides of the mounting base 10; a cover plate 11, located above the mounting base 10, with the cover plate 11 and the mounting base 10 in a movable engaging relationship; a limiting unit for pressing the wire is provided below the cover plate 11, the limiting unit including a connecting post 15 and an insulating ring 22, the top end of the connecting post 15 movably passing through the cover plate 11, and a sleeve 14 fixedly installed at the top end of the cover plate 11 at the position corresponding to the connecting post 15, with one end of the connecting post 15 elastically moving within the cavity of the sleeve 14.

[0025] An electrical connector includes a copper plate 20 fixedly installed in the cavity of a mounting base 10 and the aforementioned locking structure. A copper post 21 is fixedly installed on the top of the copper plate 20. The cross-section of the copper post 21 is T-shaped. The insulating ring 22 can be movably engaged with the copper post 21 during the descent process.

[0026] Specifically, when connecting two sets of wires, wire connectors are usually required. If the connection between the wire and the connector is not tight, pulling the wire can easily cause the wire to separate from the connector, resulting in a circuit break and potentially causing a sudden power outage and damage to the appliance. This application solves this problem by setting a movable locking mechanism between the mounting base 10 and the cover plate 11 and fixing it with bolts 12, ensuring a firm connection between the cover plate 11 and the mounting base 10. The exposed end of the wire is wrapped around the outer wall of the copper column 21. During the descent of the insulating ring 22, it can be movablely locked with the copper column 21, thereby pressing the wire down. When the end of the wire is pulled, it is not easy to separate from the copper column 21. This device is easy to install and disassemble and has high installation efficiency.

[0027] The bottom end of the cover plate 11 is fixedly provided with a plurality of clamping blocks 17, the opposite side walls of the cable placing groove 13 are both provided with clamping grooves 19, and the clamping blocks 17 are movably clamped in the corresponding clamping grooves 19. A through hole 16 is formed in the middle of the cover plate 11, a threaded groove 18 is formed in the middle of the top end of the mounting seat 10, a bolt 12 movably penetrates the through hole 16, and the bolt 12 is movably clamped in the threaded groove 18 in a threaded connection mode.

[0028] Specifically, the cover plate 11 is clamped and placed above the mounting seat 10 by fixing a plurality of clamping blocks 17 at the bottom end of the cover plate 11, forming clamping grooves 19 on the opposite side walls of the cable placing groove 13, and movably clamping the clamping blocks 17 in the corresponding clamping grooves 19. The mounting seat 10 and the cover plate 11 are fixed and limited by forming a through hole 16 at the top end of the cover plate 11, forming a threaded groove 18 at the top end of the mounting seat 10, movably penetrating the through hole 16 by the bolt 12, and screwing the bolt 12 with the threaded groove 18.

[0029] The insulating ring 22 is fixedly installed at the bottom end of the connecting column 15, the connecting column 15 is fixedly connected with a anti-disengagement plate 23 at one end in the cavity of the sleeve 14, the anti-disengagement plate 23 is movably clamped in the cavity of the sleeve 14, and a compression spring 24 is arranged between the anti-disengagement plate 23 and the top end of the inner wall of the sleeve 14.

[0030] Specifically, the insulating ring 22 is fixedly connected with the connecting column 15, the anti-disengagement plate 23 is fixedly connected with the connecting column 15 at one end in the cavity of the sleeve 14, and the compression spring 24 is arranged between the anti-disengagement plate 23 and the top end of the inner wall of the sleeve 14. When the insulating ring 22 presses one end of the wire, the anti-disengagement plate 23 compresses the compression spring 24, so that the compression spring 24 provides a downward pressure on the insulating ring 22.

[0031] The working principle of the locking structure and the wire connector thereof is as follows: when two groups of wires are connected, a wire connector is usually needed, and the connection between the wire and the connector is not tight, and the wire is easily separated from the connector when pulled, causing a circuit break, which may cause the electrical appliance to suddenly lose power and be damaged. The cover plate 11 and the mounting seat 10 are movably clamped and fixed by the bolt 12, which ensures that the cover plate 11 and the mounting seat 10 are firmly connected, the exposed end of the wire is wound around the outer wall of the copper column 21, the insulating ring 22 is fixedly connected with the connecting column 15, the anti-disengagement plate 23 is fixedly connected with the connecting column 15 at one end in the cavity of the sleeve 14, the compression spring 24 is arranged between the anti-disengagement plate 23 and the top end of the inner wall of the sleeve 14, and when the insulating ring 22 presses one end of the wire, the anti-disengagement plate 23 compresses the compression spring 24, so that the compression spring 24 provides a downward pressure on the insulating ring 22, thereby pressing the wire, and the wire end is not easily separated from the copper column 21 when pulled. The device is convenient to install and disassemble, and has high installation efficiency.
