It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] A quick connector for an electric welder provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1

[0025] Combination Figure 1-4 As shown, the utility model provides a quick connector for an electric welding machine, comprising: a connector body 100, a wire crimping assembly 200, and a clamping assembly 300; the wire crimping assembly 200 comprises a wire loading groove 201 provided at the rear end of the connector body 100, a wire crimping block 202 movably installed in the wire loading groove 201, a plurality of groups of pressing rings 203 arranged and fixedly installed at the lower part of the wire crimping block 202, a clamping block 204 fixedly installed at one side of the wire crimping block 202, a vertical groove 205 provided in the connector body 100 inside the wire loading groove 201, and a vertical groove 206 provided in the vertical groove 207. 5; the wire groove 201 is an arched structure, the wire pressing block 202 is an arc-shaped structure, and the wire pressing block 202 matches the lower part of the wire groove 201, the clamping block 204 is movably mounted in the vertical groove 205, and a threaded hole 207 is also provided in the connector body 100 at the upper part of the wire groove 201, and a hexagon socket screw 208 is movably installed in the threaded hole 207, and a notch 209 is also provided on the upper end of the wire pressing block 202, and the notch 209 matches the hexagon socket screw 208.

[0026] Specifically, the electric welding machine quick connector is a tool for connecting the circuit of the electric welding machine. The wire pressing block 202 installed on the upper part of the wire groove 201 at the rear end of the connector body 100 can be inserted into the bottom of the wire groove 201. The pressure of the hexagon socket screw 208 can press the wire pressing block 202 and the multiple groups of pressing rings 203 at the bottom to the upper end of the wire harness, thereby ensuring multiple pressing and fastening points of the wire harness while also increasing the pressing area of ​​the wire harness, thereby improving the tightness of the wire harness during pressing in the wire groove 201 to avoid the problem of the wire harness detaching. The first spring 206 installed in the vertical groove 205 and the clamping block 204 on the upper part of the first spring 206 are mainly used for lifting the wire pressing block 202 in the wire groove 201, so as to facilitate the insertion of the wire harness. The recess 209 opened on the upper part of the wire pressing block 202 is mainly used for the engagement of the hexagon socket screw 208, thereby limiting the wire pressing block 202 to avoid the problem of its detachment during pulling. Embodiment 2

[0027] Combination Figure 3-4 As shown, on the basis of the first embodiment, the clamping assembly 300 includes a mounting hole 301 opened at the front end of the joint body 100, a movable block 302 movably installed at the front end of the mounting hole 301, a plurality of friction strips 303 arranged and fixedly installed in front of the movable block 302, and a second spring 304 fixedly installed at the rear of the movable block 302. A hexagonal groove 305 is also opened in the center of the rear of the movable block 302, and a hexagonal column 306 is also fixedly installed in the center of the mounting hole 301, and the hexagonal column 306 matches the hexagonal groove 305.

[0028] Specifically, the movable block 302 installed in the front mounting hole 301 of the connector body 100 can also ensure the clamping strength and clamping friction of the connector body 100 in the connector seat through the multiple groups of friction strips 303 at the front end and the elastic force of the second spring 304 compressed in the mounting hole 301 after the connector body 100 is engaged and installed in the connector seat on the electric welding machine, so as to improve the connection tightness of the connector body 100 after engagement. The hexagonal column 306 installed in the hexagonal groove 305 at the rear end of the movable block 302 is mainly used to restrain the position of the rear end of the movable block 302 during use, so as to ensure that the friction strip 303 at its front end has good friction after being compressed.

[0029] The working principle and use process of this utility model:

[0030] When the rear end of the connector body 100 is connected to the wiring harness, the wiring harness is first inserted between the wiring groove 201 and the wire pressing block 202. After the wiring harness is inserted to the deepest, the hexagon socket screw 208 at the upper end can be tightened so that the hexagon socket screw 208 rotates into the recess 209 and then presses the wire pressing block 202 downward, thereby pressing the inserted wiring harness between the wiring groove 201 and the wire pressing block 202. While ensuring a large pressing area for the wiring harness, the multiple groups of pressing rings 203 at the bottom of the wire pressing block 202 can also form multiple groups of pressing and fastening points for the wiring harness, thereby ensuring To ensure the compression strength of the wiring harness, after the connector body 100 is pressed and rotated to be installed inside the connector seat on the electric welding machine, the movable block 302 at its front end will compress the second spring 304 at the rear end and shrink to the inside of the mounting hole 301, so that the elastic force of the movable block 302 after the second spring 304 is compressed will press the multiple groups of friction strips 303 at the front end of the movable block 302 into the connector seat to ensure the friction and engagement strength between the connector seat, thereby ensuring the tightness of the connector body 100 after it is engaged with the inside of the connector seat.
