In actual use, it is convenient to install multiple electrical appliance terminals, and when the electrical equipment is subsequently expanded, it is convenient to connect the electrical equipment with the dual power switching switch 3, thereby improving the practicality of the incoming line cabinet.

[0022] like Figure 2 and 3As shown, the connector 5 includes a U-shaped frame 51 fixedly connected to one side of the substrate 4, the inner side of the U-shaped frame 51 is fixedly connected to the partitions 52 evenly distributed along the length direction of the U-shaped frame 51, a support component 54 is fixedly connected between two adjacent partitions 52, a clamping component 53 is slidably connected to one side of the support component 54, the clamping component 53 and the support component 54 are cross-arranged, one side of the U-shaped frame 51 is threadedly connected to a plurality of evenly distributed tightening bolts 55, one end of the tightening bolt 55 is in contact with one side of the tightening component 53, the support component 54 includes an arc-shaped metal plate 541, and the four corners of the arc-shaped metal plate 541 Both are fixedly connected with a second L-shaped plate 542, one side of the second L-shaped plate 542 is fixedly connected to one side of the corresponding partition plate 52, a slide groove 543 is provided between the two second L-shaped plates 542 on the same side, one side of the arc-shaped metal plate 541 is fixedly connected with a support plate 544, one end of the support plate 544 is fixedly connected to one side of the base plate 4, the clamping component 53 includes an arc-shaped clamping plate 531, both sides of the arc-shaped clamping plate 531 are fixedly connected with a first L-shaped plate 532, the two first L-shaped plates 532 are respectively slidably connected inside the two slide grooves 543, and one side of the arc-shaped clamping plate 531 is fixedly connected with a straight plate 533.
