When connecting the wire, firstly inserting a tool into the insertion opening 4, contacting the tool with the uppermost part of the triangular bevel 702 on the central shaft 701, with the continuous force of the worker, the tool can be matched with the triangular bevel 702 to drive the central shaft 701 to ascend, the central shaft 701 can drive the housing 3, the upper pressing plate 601 and the side pressing blocks 603 in the housing to synchronously move, then one side of the wire terminal is pressed against one side pressing block 603, the other side of the wire terminal is pressed against the other side pressing block 603, and finally the wire terminal is placed between the two side pressing blocks 603, so that the wire terminal can be automatically positioned at the middle position through the matching of the first spring 602 and the second spring 604; meanwhile, under the action of the first spring 602, the bottom of the upper pressing plate 601 can be in contact with the upper surface of the wire terminal; after the connection is finished, the two sides of the wire terminal are respectively attached to the two side pressing blocks 603, the bottom of the wire terminal is attached to the bottom of the wiring port 2, the top of the wire terminal is attached to the bottom of the upper pressing plate 601, a sealed environment is formed, and impurities such as dust and floc can be effectively reduced to enter the inside of the wiring port 2.
When the wires are connected, the pull rope 7002 can be pulled by the snap ring 7003 to rotate on the connecting rod 7001, the housing 3 is driven to synchronously move after the pull rope 7002 is pulled, the upper pressing plate 601 and the side pressing blocks 603 are driven to ascend together by the housing 3 in the moving process, then the wire terminals are fixed by the method described in the second paragraph, and a sealed environment can be formed after the connection is finished, so that the possibility of safety accidents is reduced.
The wire terminal can be effectively fixed and quickly disassembled and assembled through the matching of structures such as the upper pressing plate 601, the side pressing block 603, the sliding groove 8 and the insertion opening 4, and the wire terminal can be guaranteed to be pressed through the matching of structures such as the central shaft 701 and the third spring 704; when the wire terminal is fixed and matched with the wiring port 2, a sealed environment can be formed to reduce the influence of impurities such as dust, catkins and the like; the terminal can also be suitable for wire terminals with different thicknesses and different widths, and meets more requirements in practical use; especially, when being applied to the installation of surge protector 1 that one side contains a plurality of wiring mouths 2, make things convenient for the fixed of electric wire, also can quick replacement after connecing wrong line, effectively improved work efficiency, also alleviateed staff's work burden.
