In power equipment, the terminals are referred to as wiring terminals. The terminal is divided into a single hole, a double hole, a socket, a hook and the like. The terminals are classified into copper silver plating, copper zinc plating, copper, aluminum, iron, and the like, from the material viewpoint. Terminals are often used for connecting and splicing the ends of wires to allow for a more secure connection between the wire and the appliance and between the wire and the wire. The wire nose is a common terminal, consists of a wire barrel and an annular gasket and is mainly used for aligning 4mm2The above multi-strand wires are connected. The traditional method for connecting the wire with the wire nose is that an operator manually removes an insulating layer at the end part of the wire, then plugs the wire nose into the wire nose, and then compresses the wire nose by using a wire pressing pliers. Along with the quality requirement of electric equipment to the wire junction is higher and higher, manual operation can't reach unified requirement and standard, and manual operation's intensity of labour is big, and production efficiency is lower.

The device replaces manual force application mode by the pressure provided by the movement of the air cylinder, and has the advantages of higher output pressure, higher efficiency, simple structure, firmness, durability and relatively easy maintenance. Compared with manual connection of the wire noses and the wires, the device improves the processing efficiency, but the device or other similar devices in the prior art still have the following problems when the wire noses and the wires are connected in practical use: (1) after the end part of the wire is plugged into the wire barrel of the wire nose, a large margin is always reserved in the radial direction in the wire barrel, and the end part of the wire cannot be well fixed by simply pressing the wire barrel, so that the end part of the wire is easy to fall off from the wire nose in later use; (2) when the wire nose is adopted to connect two wires, after the end part of one wire is fixed in the wire barrel, the end part of the other wire still needs to be manually penetrated through the middle hole of the annular gasket and then the wire is tightly hinged, and the requirement on experience of an operator in the punching process is high, so that the processing efficiency is low.

And step two, placing the thin copper bar into a cavity formed by the baffle 5 and the sealing plate 7 along the direction parallel to the strip-shaped gap 6, and inserting the end part of one lead into the terminal wire barrel after removing the insulating layer.
And step three, pushing the first push plate 16 and the second push plate 17 to drive the first sliding rod 14 and the second sliding rod 15 to move oppositely, so as to drive the first pressing plate 18 and the second pressing plate 19 to move oppositely to extrude the two sides of the terminal wire barrel, and thus fixing the lead in the terminal wire barrel.
Step four, in the process that the first pressing plate 18 and the second pressing plate 19 move in the opposite direction, the first connecting rod 20 and the second connecting rod 21 drive the first rack 22 and the second rack 23 to move in the opposite direction, so that the first gear rod 10 and the second gear rod 11 are driven to rotate to convey the thin copper rod, the thin copper rod falls into the terminal wire barrel through the strip-shaped gap 6, and the empty space in the wire barrel is filled until the first limiting block 27 and the second limiting block 28 abut against the mounting frame 4.
And step five, lifting the telescopic rod 36 to separate the first wire pipe 35 from the second wire pipe 37, pushing the sliding block 3 to enable the inner ring of the terminal annular gasket to be positioned between the first wire pipe 35 and the second wire pipe 37, and resetting the telescopic rod 36 to enable the top end of the first wire pipe 35 to be butted with the bottom end of the second wire pipe 37.
And step six, another lead is inserted into the horizontal end part of the second conduit 37 and is penetrated out of the horizontal end part of the first conduit 35, and the end part of the lead is pressed on the second mounting plate 34 through the pressing block 39. The second spool 37 is lifted while the slider 3 is slid in a direction away from the second spool 37, and the wire is elongated to produce a margin.
And seventhly, resetting the second wire tube 37, enabling the top end of the first wire tube 35 to be in butt joint with the bottom end of the second wire tube 37, and rotating the third rotating shaft 32 to drive the first mounting plate 33 and the second mounting plate 34 to rotate, so that the part of the wire with the allowance is hinged tightly. The portion of the wire in the first conduit 35 is pulled out and cut.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
