[0017] As Figs. 1-2As shown in the figure, a two-piece double-pressing plate with insulation partition includes a first conductive screw 1, a second conductive screw 2, a connecting piece assembly 3, a sleeve 4 and a protective shell 5. The first conductive screw 1 and the second conductive screw 2 correspondingly pass through two screw sleeves 51 arranged side by side on the protective shell 5. The sleeve 4 is sleeved on the first conductive screw 1 and the second conductive screw 2 respectively. The lower end of the sleeve 4 abuts against the inner wall of the screw sleeve 51. The connecting piece assembly 3 includes an upper connecting piece 31, a lower connecting piece 32, a knob handle 33 and a lower protective shell 34. The lower protective shell 34 wraps the lower connecting piece 32. The first end of the upper connecting piece 31, the lower connecting piece 32 and the lower protective shell 34 is movably connected with the first conductive screw 1. The second end of the upper connecting piece 31, the lower connecting piece 32 and the lower protective shell 34 is connected with the second conductive screw 2. The knob handle 33 is installed on the upper connecting piece 31. The lower end of the knob handle 33 penetrates the lower protective shell 34 and is connected with the lower connecting piece 32. Specifically, in this embodiment, the first conductive screw 1 and the second conductive screw 2 are sleeved with the sleeve 4, which is inserted into the screw sleeve 51 of the protective shell 5. The sleeve 4 is used to enhance the insulation and ensure the safety in use. The connecting piece assembly 3 is used to electrically connect the first conductive screw 1 and the second conductive screw 2, so as to realize the communication of the signal loop and the tripping loop. The connecting piece assembly 3 includes the upper connecting piece 31, the lower connecting piece 32, the knob handle 33 and the lower protective shell 34. When the tester rotates the knob handle 33, the upper connecting piece 31, the lower connecting piece 32 and the lower protective shell 34 can be driven to rotate synchronously around the first conductive screw 1. When the upper connecting piece 31, the lower connecting piece 32 and the lower protective shell 34 contact the second conductive screw 2, the upper connecting piece 31 and the lower connecting piece 32 can realize the communication of the signal loop and the tripping loop. At this time, the lower protective shell 34 partitions between the upper connecting piece 31 and the lower connecting piece 32, so as to play the role of electrical isolation, avoiding the too small spacing between the upper connecting piece 31 and the lower connecting piece 32, which can easily cause safety accidents due to electrical connection.
[0018] As shown in the figure, Figs. 1-2 The second end of the upper connecting piece 31 and the lower connecting piece 32 is provided with a notch 311.

[0019] As shown in the figure, Fig. 2As shown, the middle part of the first and second conductive screw rods 1 and 2 is sleeved with an elastic sheet 6, and the second ends of the upper and lower connecting sheets 31 and 32 are movably abutted against the upper surface of the elastic sheet 6. Specifically, the elastic sheet 6 is in the shape of a ring and is sleeved on the first and second conductive screw rods 1 and 2. When the notches 311 of the upper and lower connecting sheets 31 and 32 “bite” the first and second conductive screw rods 1 and 2, the elastic sheet 6 can be elastically abutted against the lower surface of the second ends of the upper and lower connecting sheets 31 and 32, so as to increase the contact area and improve the electrical connection performance.
[0020] As shown in the drawings, Fig. 2 As shown, the middle part of the first and second conductive screw rods 1 and 2 is provided with a protrusion 11, the upper end of the sleeve 4 is provided with a notch groove 41 corresponding to the protrusion 11, and the lower surface of the elastic sheet 6 is abutted against the protrusion 11. Specifically, in this embodiment, in order to prevent the elastic sheet 6 sleeved on the first and second conductive screw rods 1 and 2 from freely falling, the protrusion 11 is arranged on the outer peripheral wall of the first and second conductive screw rods 1 and 2, the protrusion 11 supports the elastic sheet 6, and the notch groove 41 is arranged on the side of the sleeve 4 to accommodate the protrusion 11, thereby playing a role of avoiding.
[0021] As shown in the drawings, Figs. 1-2 As shown, the top ends of the first and second conductive screw rods 1 and 2 are sleeved with an insulating sleeve 12, so that the top ends of the first and second conductive screw rods 1 and 2 are insulated from the outside, thereby ensuring the safety of operation.
[0022] As shown in the drawings, Figs. 1-2 As shown, the lower ends of the first and second conductive screw rods 1 and 2 are provided with connecting heads 13, so as to facilitate the connection of wire harnesses.
