[0035] like Figures 1 to 5 As shown, the embodiment of the present application provides a welding machine power plug structure 7 and a welding machine including the power plug connector 7, wherein the welding machine includes the power plug structure 7 and a housing, and the power plug structure 7 is fixedly mounted on the housing of the welding machine. Figure 1 and Figure 2 As shown, the plug structure 7 includes a plug body 703 and a pin 701. The pin 701 is formed in the plug body 703 by encapsulation, and the pin 701 is formed from the mating surface 7031 (marked at Figure 3 ) extends forward. The rear end of the pin 701 is provided with a first wire pressing hole 709. In this embodiment, the first wire pressing hole 709 is an M3 threaded hole, which can press the wire by locking the M3 screw. Figure 1 As shown, the first surface of the plug body 703 (the upper surface of the plug body 703 in this embodiment) is provided with a notch 708 extending to the mating surface, and the notch 708 is located between the two pins 701. The notch 708 can constrain the left-right direction or the up-down direction of the pins 701. Figure 2 As shown, the second surface of the plug body 703 (the lower surface of the plug body 703 in this embodiment) is provided with a grounding spring 707, and one end of the grounding spring 707 is provided with a grounding wire pressing hole 706, so the grounding wire can be grounded through the grounding wire pressing hole 706 on the grounding spring 707, which meets the safety design. The tail of the pin 701 body is provided with a second pressing hole 705, and when necessary, the wire can be pressed by screws and a pressing cover plate to improve the reliability of the wire connection.

[0036] like Figures 3 to 5As shown, the housing of the electric welder includes a first housing 1 and a second housing 8, and the electric welder also includes a core module 3, a welding clamp 4 and a grounding clamp 2. The core module 3 includes a circuit board 301 and various components arranged on the surface of the circuit board 301. The welding clamp 4 and the grounding clamp 2 are fixed to the core module 3. The pin 701 is electrically connected to the core module 3 through a wire to input an external AC power supply into the core module 3, and the core module 3 is powered. After processing the external power supply, the core module 3 outputs a driving DC power supply to the welding clamp 4.

[0037] In this embodiment, the plug body 703 is provided with a first mounting portion and a fastener fixing portion. The housing of the electric welder is provided with a second mounting portion and a fastener mounting portion. The first mounting portion of the plug body 703 is embedded with the second mounting portion of the housing, and the fastener fixing portion of the plug body 703 is fixedly connected with the fastener mounting portion of the housing by a fastener, so that the plug structure 7 is directly fixedly installed on the housing of the electric welder, eliminating the use of a power cord, which is conducive to reducing the overall production cost of the electric welder, and the user can use it with the power strip he needs when using it, and the purpose of adjusting the working radius can be achieved without the need to separately set the welding clamp clamp 4 and the grounding clamp 2. The use method and application scenario of the electric welder with the power plug structure 7 are more flexible.

[0038] In this embodiment, the first mounting portion includes a mounting groove 702, and the second mounting portion includes a mounting column, and the mounting column is embedded in the mounting groove 702. The fastener is a screw 9, and the fastener fixing portion is a screw hole 704. The fastener mounting portion includes a screw column, and the screw 9 is inserted into the screw hole 704 and the screw column. Figure 3 and Figure 4As shown, the housing of the electric welding machine includes a first housing 1 and a second housing 8, the inner wall of the first housing 1 is provided with a first mounting column 101, and the inner wall of the second housing 8 is provided with a second mounting column 801. In this embodiment, the cross-sections of the first mounting column 101 and the second mounting column 801 are both quadrilateral, and the cross-section of the mounting groove 702 is also quadrilateral, which can play a guiding role when the first mounting column 101 and the second mounting column 801 are inserted into the mounting groove 702, and also play a guiding and limiting role in the alignment assembly of the first housing 1 and the second housing 8, and prevent the plug structure 7 from rotating compared with the first housing 1 and the second housing 8, so as to maintain the assembly stability of the plug structure 7. The fastener mounting portion includes a first screw column 102 provided on the first housing 1 and a second screw column 802 provided on the second housing 8, and threaded holes are respectively provided in the first threaded column 102 and the second threaded column 802. Therefore, the first housing 1, the lower housing and the plug structure 7 can be fixedly installed together by only one screw 9. And the screw 9 is arranged at the edge of the housing, and will not occupy too much space inside the housing. Furthermore, even if the plug structure 7 is repeatedly plugged in and out during use of the electric welding machine, a stable and reliable connection between the plug structure 7 and the housing can be maintained.

[0039] In this embodiment, the plug structure 7 is fixedly mounted on the housing of the electric welder in a direction perpendicular to the working horizontal plane of the plug structure 7. The first mounting column 101 and the second mounting column 801 extend in a direction perpendicular to the working horizontal plane of the plug structure 7, respectively, and the mounting groove 702 also extends in a direction perpendicular to the working horizontal plane of the plug structure 7. The screw 9 is sequentially penetrated through the second screw column 802, the screw hole 704 and the first screw column 102 in a direction perpendicular to the working horizontal plane of the plug structure 7. The working horizontal plane of the plug structure 7 here refers to a plane perpendicular to the mating surface 7031 of the plug body 703, and the working horizontal plane is parallel to the upper surface or lower surface of the electric welder. After the plug structure 7 is installed on the housing of the electric welder, the electric welder is laid flat, and the mating surface 7031 of the plug structure 7 is vertical, which is easier to mate with the power socket.

[0040] When assembling the electric welder, the plug structure 7 is installed on the second housing 8, the second mounting column 801 is inserted into the mounting groove 702, and then the first housing 1 is assembled with the second housing 8, and the first mounting column 101 of the first housing 1 is inserted into the mounting groove 702. At this time, the centers of the first screw column 102, the screw hole 704 and the second screw column 802 are on the same straight line, and the screw 9 is sequentially inserted into the second screw column 802, the screw hole 704 and the first screw column 102, that is, the installation and fixation of the plug structure 7 is completed, and the assembly stability of the first housing 1 and the second housing 8 can be maintained by the screw 9. The plug structure 7 provided in the present application is a modular structure. Different types of plug structures 7 can be replaced according to the use requirements and assembled with the housing of the electric welder. For example, in view of the situation that different regions have different socket standards, a plug structure 7 compatible with the socket of the corresponding region can be selected. As long as the plug body 703 of the plug structure 7 has a first mounting portion and a fastener fixing portion, the plug structure 7 can be fixedly installed on the electric welder. Moreover, when the electric welder is used in different scenarios, the corresponding plug structure 7 can be easily replaced according to the required socket standard, so that the electric welder with the power plug structure 7 has higher versatility and is more suitable for wide promotion and application. When the plug structure 7 fails, the plug structure 7 can also be replaced alone without affecting other parts of the electric welder.

For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
