[0002] Single-phase grounding faults can lead to electric shock accidents, electrical fires, and reduced power supply reliability. Therefore, the management of single-phase grounding faults has become a normalized work content faced by the industry. Among them, there are two key management aspects, one is arc elimination, and the other is detuning.

[0003] Terminal block connectors are common electronic accessories in the electromechanical field and are widely used in life and production. Terminal block connectors are bridges of communication between blocked circuits or isolated circuits, enabling current to flow and the circuit to achieve its intended function.

Among them, when a single-phase grounding fault occurs in the distribution network system, the impedance grounding transformer in the intelligent grounding device is used to suppress the resonance generated in the fault; when a non-single-phase grounding fault in the distribution network causes overvoltage and line resonance, the nonlinear detuning characteristics of the PTC are used to actively suppress the resonance to avoid the harmonic impact of the resonance on the distribution network system.

[0053] In the wiring process of the controller of the harmonic elimination device, wiring terminals are required. The wiring structure of the current limiting harmonic elimination device of the present invention solves the wiring problem of the controller well and improves the convenience and stability of the wiring. The application of the present invention is introduced in conjunction with the embodiments below. Embodiment 1

[0055] The wiring assembly 200 includes a housing 220, in which a wire end processing chamber 221 and a wiring chamber 228 are provided; the inner wall of the wire end processing chamber 221 is provided with two symmetrically distributed sixth grooves 227, and a cutter 243 is provided in each of the sixth grooves 227; on the connecting line of the center points of the two cutters 243, the two cutters 243 can move linearly toward or away from each other; the inner wall of the wire end processing chamber 221 is provided with two symmetrically distributed fourth grooves 225, and the connecting line of the center points of the two fourth grooves 225 is perpendicular to the two The connecting line of the center point of the sixth slot 227, at least one puncture needle 236 is arranged in each of the fourth slots 225, and the puncture needles 236 in the two fourth slots 225 are symmetrically distributed in pairs; on the connecting line of the center points of every two symmetrically distributed puncture needles 236, every two puncture needles 236 can make a linear motion towards or away from each other; the end of the wiring cavity 228 located on the side away from the wire end processing cavity 221 is fixedly connected with a conductive sheet 280, and the conductive sheet 280 is connected to the tail of the first terminal shell 310 or the tail of the second terminal shell 410.

[0056] When the wiring assembly 200 is used in conjunction with the first wiring terminal 300 and the second terminal, the wire 120 is first inserted into the wire end processing chamber 221, and the insulation skin of the wire 120 is cut by the two cutters 243 in the wire end processing chamber 221. The insulation skin cut in the wire end processing chamber 221 is divided into two parts, and at least one piercing needle 236 located on both sides is inserted into the insulation skin, and the two insulation skins are respectively driven to be recovered into the fourth groove 225 by the piercing needle 236. This step can complete the treatment of the insulation skin. After the treatment, continue to insert the inner core of the wire 120 into the conductive wire in the wiring chamber 228. On the sheet 280, at the same time, a wire pressing assembly can be arranged on the shell 220, so that the core of the wire 120 can be in contact with the conductive sheet 280 as much as possible, ensuring the contact area between the core of the wire 120 and the conductive sheet 280, improving the connectivity between the core of the wire 120 and the conductive sheet 280, and reducing the contact resistance. The pressing belt has a certain elasticity, so that when the pressing belt squeezes and fixes the core, it will not cause damage to the core, avoiding fatigue fracture of the core, and ensuring the contact effect between the core of the wire 120 and the conductive sheet 280. All of the above are prior arts, which are well-known technical means in the field and will not be described in detail.

[0058] like Figure 7 , Fig. 9 As shown, in the present invention, in order to realize that the cutters 243 can make a linear movement towards or away from each other on the connecting line of the center points of the two cutters 243, a force rod 240 is fixedly connected to the top of the cutters 243, the force rod 240 is slidably connected to the housing 220, and the end of the force rod 240 extends out of the housing 220 and is fixedly connected to an end plate 241, and the bottom of the end plate 241 is connected to the surface of the housing 220 through a spring 242, and the spring 242 is sleeved on the outside of the force rod 240, and the spring 242 is always in a compressed state. When in use, the movement of the cutters 243 towards each other can be completed by squeezing the two end plates 241, and after the end plates 241 are released, the two cutters 243 are recovered into the sixth slot 227 by the elastic force of the spring 242. This method allows the cutters 243 to move closer to or further away from each other on the connecting line of the center points of the two cutters 243, which is a preferred solution of the present invention. Other feasible solutions are also possible, such as: by setting a micro telescopic motor on the surface of the shell 220 and achieving it by motor drive.

[0059] like Figure 4 , Figure 5 and Figure 7As shown, in the present invention, in order to realize that on the connecting line of the center points of each two symmetrically distributed puncture needles 236, each two puncture needles 236 can make a linear motion close to or away from each other, the inner wall of the shell 220 is provided with two symmetrically distributed first grooves 222, and a sliding connection nut seat 233 is arranged in the first groove 222. The nut seat 233 can make a reciprocating linear motion along its own axis. At least one folding rod 234 is fixedly connected to the nut seat 233.

The installation, fixation and disassembly between the first shell 220a and the second shell 220b are realized by the cooperation between the threaded protruding ring 221a and the threaded ring groove 221b.

[0070] At the same time, in this setting, the puncture needle 236 can be set as close to the second shell 220b as possible, so that when the sensor needs to be replaced, it is only necessary to loosen the clamping of the slide 260 on the wire 120, pull out the wire end placed in the wiring cavity 228, cut the wire 120 at the cavity mouth of the wire end processing cavity 221 close to the sensor side, and pour out the wire core of the wire 120 in the wire end processing cavity 221; after using the wiring structure many times, when there is too much insulation skin in the fourth groove 225 that affects the use, the first shell 220a and the second shell 220b are separated, and after separation, the insulation skin layer is removed from the puncture needle 236 with a tool.

[0071] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
