Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, and more specifically relates to a crown spring plug-in type secondary wire connecting device for electric welding machines. Background Art

[0002] Welding technology is widely used in all walks of life. The secondary wire is the output wire coil of the electric welding machine. When working, it needs to be connected to the weldment to form a current loop. The connection method between the secondary wire and the weldment is generally to wrap the secondary wire around the weldment to achieve connectivity between the two.

[0003] However, in actual on-site work, it is often the case that there is no space for secondary wires to be wound around the components that need to be welded (such as welding a 3m*6m open flat plate). In this case, the secondary wires can only be wound around adjacent equipment, which will cause the secondary wires to be too long and may also cause problems such as arc burns on the equipment.

[0004] In actual work, the secondary wires are often delayed, the connection is unstable, and the connection points of the secondary wiring are seriously rusted and oily, resulting in poor contact of the secondary wires, arc breaking, sparking, and even arc failure. In addition, the traditional secondary wire winding connection method has the disadvantages of slow speed and loose connection. When storing, the fixed base must be stored together with the wire harness, which interferes with each other and rubs, which is easy to wear and reduce the service life. Utility Model Content
