[0032] The elastic sheet 21 is provided with two intervals to form a clamping groove; the metal connecting piece 2 is moved along the direction from one end to the other end, so that the terminal post 5 is pushed into the clamping groove along the radial direction thereof and is clamped by the clamping groove.
[0033] The present application adopts a metal connecting piece 2 with a clamping groove, and the terminal post 5 is communicated with the power line 4 by a push-in mode, and since the outer peripheral wall of the terminal post 5 is in contact with the metal connecting piece 2, the contact area of the two is increased, so that the stability is better improved.
[0034] The metal connecting piece 2 can make the power line 4 and the terminal post 5 achieve electrical connection, and the electrical connection is formed by pushing the metal connecting piece 2 along the radial direction of the terminal post 5, which is simple to operate, and the metal connecting piece 2 and the terminal post 5 are in surface contact mode, so that the stability is improved.
[0035] For the connection of the power line 4 and the metal connecting piece 2, the joint of the power line 4 can be inserted into one end of the metal connecting piece 2, and a wire clamping structure is arranged on the metal connecting piece 2, so that the power line 4 and the metal connecting piece 2 form a stable conduction state.
[0036] In some embodiments, the elastic sheet 21 comprises a wave-shaped structure along the pushing direction of the terminal post 5.
[0037] The wave-shaped structure of the elastic sheet 21 is used to lock and limit the terminal post 5 after the terminal post 5 slides into the metal elastic sheet 21, so that the stability of the contact is improved, and the falling off is prevented.
[0038] In some embodiments, the other end of the metal connecting piece 2 is further provided with two balance arranged cantilevers 22, the elastic sheet 21 is fixed on the opposite side walls of the two cantilevers 22, and the two sides of the elastic sheet 21 protrude from the cantilevers 22.
[0039] The area of the elastic sheet 21 is larger than the structure of the metal connecting piece 2 itself, so that the contact area of the elastic sheet 21 and the terminal post 5 is enlarged, and the stability of the electrical connection is further improved.
[0040] In some embodiments, the plug-in terminal assembly further comprises a terminal 3 made of insulating material, the terminal 3 comprises a through hole penetrating through both sides, one end of the through hole is provided as a through slot 32, and the metal connecting piece 2 is inserted into the through slot 32 along the through hole.
[0041] The terminal 3 is made of insulating material, the metal connecting piece 2 is inserted into the terminal 3, the safety of operation is improved, and the terminal 3 is convenient to control to clamp the terminal post 5.
[0042] In some embodiments, the side wall of the through slot 32 is provided with a slot 321, and the cantilever 22 is inserted into the slot 321.
[0043] The metal elastic sheet 21 is inserted into the slot 321 at one end of the terminal 3 through the cantilever 22, preferably, a clamping mechanism is arranged on the inner wall of the through hole and the outer wall of the metal connecting piece 2, so that the metal connecting piece 2 is clamped in the through hole, more preferably, a buckle is arranged on the inner wall of the through hole, and a groove 23 is arranged on the outer wall of the metal connecting piece 2, and the buckle and the groove 23 are matched and clamped.
[0044] The buckle in the terminal 3 slides into the groove 23 in the elastic sheet 21, so that the elastic sheet 21 is limited to be loosened outwardly; in order to limit the insertion degree of the metal connecting piece 2 into the terminal 3, a limiting structure capable of blocking the elastic sheet 21 is arranged in the insertion direction, so as to limit the elastic sheet 21 to be loosened inwardly. In this way, the metal connecting piece 2 can be stably arranged in the terminal 3.
[0045] Generally, three wiring posts 5 are arranged in a triangular shape; the terminal 3 with the three metal connecting pieces 2 arranged therein is also arranged in a triangular shape, and corresponds to the positions where the wiring posts 5 are pushed in respectively. At this time, the compressor power line 4 forms a continuous conduction with the wiring post 5 through the metal elastic sheet 21, and during the operation of the machine, the current can be conducted to the metal elastic sheet 21 from the power line 4 and then to the wiring post 5, so that the compressor can effectively operate.
