A welding power supply device

Abstract

The invention discloses a welding device. The welding device comprises a rack and an electric terminal inserted into the rack for matched connection, wherein an internal groove extending left and right is formed in the rack; an inserting groove is communicated between the right end of the internal groove and the exterior of the rack; a parting strip fixedly connected with the rack is arranged at the right end of the internal groove and located above the inserting groove; an open groove extending upwards is formed in the parting strip; the left end of the open groove is communicated with the internal groove, the right end is communicated with the exterior of the rack, and the lower part is communicated with the inserting groove. The welding device is simple in overall structure, low in production cost, high in power supply safety and stability and simple to run and operate, electric shock accidents in existing life are effectively reduced, life and property safety of people is guaranteed, besides, power outage accidents of the welding device due to mistaken kicking and mistaken collision can be avoided, the service life of the welding device is effectively protected, and the welding device is suitable for being popularized and used.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding power supply device. Background technique [0002] When the welding machine is in use, the plug of the welding machine needs to be connected with the socket, so as to provide electricity for the welding machine. The plug of the existing welding machine and the electrical interface of the socket are all in the form of plug-in connection, and there is no lock for the plug. Once the wire on the plug is pulled by an external force, the plug will be pulled out of the electrical interface on the socket, so that the power supply of the welding machine will stop, resulting in unstable power consumption of the welding machine, and in severe cases, it will damage the electrical interface on the plug or socket , and the socket of existing welding machine all is direct energization, also may cause the generation of electric shock accident in the process of plug plugging and unplug...
