[0035] Specifically, in order to make it more conductive, the wiring conductive plate 21 is made of a conductive metal material, and the width of the wiring interface 2121 formed by the connection portion 211 and the wire insertion portion 212 is larger than the diameter of the wire, so that the wire can be more easily connected. In order to make the wire more firmly connected to the wiring interface 2121, the wire insertion portion 212 continues to extend at one end of the bayonet 2122, and the other end is flush with the bayonet 2122. The purpose of this design is that when the wire is connected to the wiring interface 2121, the extended end can limit the wire and clamp it. Tight, so that the wire is more firm and reliable after being plugged in. At the same time, the bayonet 2122 is set to a V-shaped structure in order to better cooperate with the wiring spring piece 22 to avoid friction with it and affect the service life; the fixed part can stably connect the wiring part 212, and a positioning block 214 is set to quickly connect with the wiring spring piece 22; the conductive part 213 is bent multiple times away from the fixed part, and a conductive contact 215 is set at its end, the purpose of which is to save space according to the structure of the shell 1 and the rocker contact piece 4, and to facilitate the connection of the conductive contact 215 with the rocker contact piece 4 for conduction.

[0036] In this embodiment, if Figure 8 As shown, the wiring spring piece 22 includes a fixing piece 221, a connecting piece 222, a clamping piece 223 and a pressure piece 224 which are connected in sequence and integrally formed. The fixing piece 221 is fitted with the connecting portion 211, and a positioning hole 2211 is opened at the position of the fixing piece 221 corresponding to the positioning block 214.

[0037] Specifically, when installing the wiring spring piece 22, it is only necessary to insert one end of the connecting piece 222 on the wiring spring piece 22 along the direction of one end of the conductive part 213 on the wiring conductive plate 21, and insert the fixing piece 221 into the gap between the wire insertion parts 212 until the positioning hole 2211 is snapped into the positioning block 214 to complete the positioning installation. At this time, the wiring spring piece 22 is completely accommodated in the wiring conductive plate 21; wherein, the rigidity of the connecting piece 222 is greater than that of the clamping piece 223, because when the wiring spring piece 22 is squeezed, the connecting piece 222 needs to be deformed repeatedly, so the rigidity of the structure at this location is relatively strong; and the clamping piece 223 is arranged at the position corresponding to the wiring interface 2121, in order to facilitate the connection between the pressure piece 224 and the disassembly button, the card slot 225 opened between the clamping piece 223 and the pressure piece 224 can Avoid obstruction, and the slot 225 is adapted to the slot 2122, making it smoother during the pressing process; and the width of the pressure piece 224 is smaller than the clamping piece 223. When the wire is not inserted, the pressure piece 224 is located in the gap between the wire insertion part 212 and is directly opposite to the disassembly button. Therefore, after the disassembly button is pressed, the force on the sharp end 2241 on the pressure piece 224 is applied. The structure of the sharp end 2241 can quickly bend the pressure piece 224 together with the clamping piece 223 and the connecting piece 222 downward and deform when squeezed by the disassembly button, so that the clamping piece 223 located in the wiring interface 2121 is disengaged along the direction of the slot 225, and the wiring interface 2121 is restored to a complete arc-shaped channel structure, so that the wire can be quickly plugged into the wiring interface 2121 and be compressed between the clamping part and the wire insertion part 212.

[0038] The working principle of this utility model:

[0039] When using the utility model wiring terminal to make connections, insert the wire into the wiring interface 2121, and press the wire removal button 3 at the same time, so that the wiring spring piece 22 is compressed downward under the action of the wire removal button 3, so that the wire can be easily connected to the wiring interface 2121, and then release the wire removal button 3, the wiring spring piece 22 resets and compresses the wire under the action of elastic force, and the wire cutting groove 2231 removes part of the insulation skin of the wire, so that the copper wire inside is exposed, and the wire is clamped in the wiring conductive plate 21 by relying on the elastic force of the wiring spring piece 22, so as to ensure the clamping force between the wire and the wiring conductive plate 21. When the wire needs to be loosened during daily operation and maintenance, the wire can be removed by pressing the wire removal button 3, so that it has the characteristics of quick wiring, flexible installation and high safety, and can be applied to a variety of wiring scenarios, saving a lot of wiring time, and ensuring efficient and flexible load and control current distribution.
