[0029] Referring to Figures 3-8The extension directions of the two wire terminals 30 are opposite, so that the two wire terminals 30 respectively extend to the first side 101 and the second side 102 of the shell 10. Specifically, the two wire terminals 30 are rotationally symmetrically arranged around a center axis. In this embodiment, the two wire terminals 30 are rotationally symmetrically arranged around the center axis of the shell 10. The wire terminal 30 comprises a first segment 31 and a second segment 32 connected to each other, the first segment 31 and the second segment 32 are perpendicular to each other, the extension directions of the first segments 31 of the two wire terminals 30 are opposite, the extension directions of the second segments 32 of the two wire terminals 30 are opposite, so that the second segments 32 of the two wire terminals 30 respectively extend to the first side 101 and the second side 102 of the shell 10, and the second segments 32 of the two wire terminals 30 are respectively close to the third side 103 and the fourth side 104 of the shell 10, the third side 103 and the fourth side 104 are two sides of the shell 10 that are away from each other; the two wire terminals 30 with opposite extension directions are physically farther apart, and are more reasonably arranged, so that the contact system 1 has a larger wiring space, and the installer is more convenient to operate; and the electrical safety distance between the two wire terminals 30 is larger, and the wiring position is also farther away from the central contact structure, so that the safety is improved.

[0030] The second segment 32 of the wire terminal 30 is clamped with the clamping piece 20. The clamping piece 20 comprises a first branch arm 21, a second branch arm 22, a buckling part 25, a rotation part 23 connecting the first branch arm 21 and the second branch arm 22, and a transition part 24 connecting the second branch arm 22 and the buckling part 25. The clamping port 251 is buckled at the end of the first branch arm 21, so that the clamping piece 20 as a whole forms a ring structure capable of being end-to-end lapped. The first branch arm 21 is used to abut and contact the wire terminal 30, and an electrical connection is realized therebetween. Specifically, the side of the first branch arm 21 away from the second branch arm 22 is defined as the back side of the first branch arm 21, and the second segment 32 of the wire terminal 30 abuts against the back side of the first branch arm 21. Similarly, the side is also defined as the back side of the second segment 32 of the wire terminal 30, i.e. the back side of the second segment 32 of the wire terminal 30.

[0031] The clamping piece 20 can be deformed by external force, so that the second branch 22 can rotate around the rotating part 23 relative to the first branch 21, and the clamping part 25 is moved at the same time. The movement of the clamping part 25 makes the clamping interface 251 move towards the back side of the first branch 21, so that the clamping interface 251 is at least partially exposed to the back side of the first branch 21, and at least partially exposed to the back side of the terminal 30, that is, exposed to the back side of the second section 32 of the terminal 30, and at least part of the clamping interface 251 exposed to the back side of the terminal 30 can be used for inserting the end of the wire 5.

[0034] Continuing to refer to Figure 6 , Figure 8 , the end of the clamping part 25 is provided with an inclined section 252, which can reduce the space occupation of the end of the clamping part 25, so as to more facilitate the full use of space to arrange the clamping piece 20. In addition, the inclined section 252 can also improve the structural strength of the end of the clamping part 25 to a certain extent.

[0035] Further, the shell 10 is provided with a positioning boss 14, and the clamping piece 20 is sleeved on the positioning boss 14, so that the clamping piece 20 can be better installed and positioned on the shell 10. The positioning boss 14 includes a positioning head 141 with a cross section at least partially circular, and the positioning head 141 corresponds to the circular arc-shaped rotating part 23, so that the clamping piece 20 can be better positioned on the shell 10 when it is elastically deformed.

[0036] Referring to Figure 7、 Figure 8 The turning part 23 is bent and transitioned at the abutment 26 of the second branch arm 22, so that the turning part 23 protrudes from the second branch arm 22, and the stress condition of the turning part 23 is better.

[0037] The contact system 1 can realize artificial rapid plugging of cable joints by applying the clamping piece 20 of the elastic sheet structure, solves the screw mechanical locking operation mode of the traditional rotary disconnecting switch, is especially suitable for small current rotary disconnecting switches, and improves the wiring efficiency.
