[0055] Reference Figures 1 to 11 As shown, this embodiment provides a terminal block, which includes a mounting base 100, a wiring assembly 200, and a lever 300.

[0056] Specifically, the mounting base 100 is provided with a limiting hole 101 extending in a first direction; the wiring assembly 200 is provided at the first end of the limiting hole 101 in the first direction, and the wiring assembly 200 includes a terminal block 210 and an elastic element 220; the lever 300 passes through the limiting hole 101, and the lever 300 includes a rod body 310 extending in the first direction, a limiting protrusion 320 and a fulcrum structure 330 provided on the rod body 310, the first end of the rod body 310 and the limiting protrusion 320 protruding from the first end of the limiting hole 101, and the second end of the rod body 310 protruding from the second end of the limiting hole 101.

[0057] The limiting protrusion 320 and the first end of the limiting hole 101 form a limiting fit along the first direction, which effectively prevents the rod body 310 from detaching from the second end of the limiting hole 101.

[0058] The fulcrum structure 330 is located inside the limiting hole 101. The rod body 310 forms a lever engagement with the side wall of the limiting hole 101 through the fulcrum structure 330. The rod body 310 swings relative to the mounting base 100 in a second direction and has a first position and a second position.

[0059] In the diagram, direction a is the first direction, direction b is the second direction, and direction c is the third direction. The first, second, and third directions can be set perpendicular to each other.

[0060] In the first position, the first end of the rod body 310 abuts against the elastic member 220, and a gap is formed between the elastic member 220 and the terminal block 210 that allows wires to pass through.

[0061] In the second position, the elastic element 220 and the terminal block 210 can clamp and fix the wire.

[0062] In this embodiment, the fulcrum structure 330 serves as a lever fulcrum. When installing or removing wires, the second end of the rod body 310 is moved, causing the rod body 310 to swing relative to the mounting base 100 in a second direction to a first position. The first end of the rod body 310 presses against the elastic element 220, thereby creating a gap between the elastic element 220 and the terminal block 210 to release the wires or provide space for wire insertion. This facilitates wire installation and removal, is highly efficient, and is convenient for on-site installation and removal. Even in environments with impact and vibration, the compression and fixation of the wires by the elastic element 220 remains stable and reliable. Releasing the second end of the rod body 310 causes the first end of the rod body 310 to swing relative to the mounting base 100 in a second direction towards a second position under the elastic force of the elastic element 220.

[0063] For example, the rod body 310 is provided with limiting protrusions 320 on both sides along the second direction to form a more stable limiting fit.

[0064] For example, the mounting base 100 is provided with a wiring channel 102, through which wires can pass through the wiring channel 102 and pass through the gap formed between the elastic member 220 and the terminal block 210.

[0065] In some embodiments, reference Figure 1 and Figure 2As shown, the fulcrum structure 330 includes a first arc surface 331 and a second arc surface 332. The first arc surface 331 is located on the first side of the rod body 310 along a third direction and abuts against the wall of the limiting hole 101. The second arc surface 332 is located on the second side of the rod body 310 along a third direction and abuts against the wall of the limiting hole 101. The first arc surface 331 and the second arc surface 332 are spaced 180° apart around the second direction. In this embodiment, the lever fulcrum is formed by the cooperation between the first arc surface 331 and the second arc surface 332 and the wall of the limiting hole 101. The assembly between the lever 300 and the mounting base 100 can be completed simply by passing the second end of the rod body 310 through the first end of the limiting hole 101, which facilitates assembly.

[0066] For example, to ensure that the rod body 310 has a sufficiently large swing angle, the rod portion of the rod body 310 with the fulcrum structure 330 can be inclined, that is, this rod portion is set at an angle to both the first end and the second end of the rod body 310. Furthermore, the inclined arrangement of the rod portion of the rod body 310 with the fulcrum structure 330 can effectively prevent the first end of the rod body 310 from entering the limiting hole 101, and more effectively prevent the rod body 310 from detaching from the second end of the limiting hole 101. For example, the first end and the second end of the rod body 310 can be arranged parallel to each other.

[0067] For example, to prevent the lever 300 from disengaging from the first end of the limiting hole 101, a limiting structure (not shown) can be provided on the lever body 310. In some embodiments, the limiting structure can be a limiting pin, which passes through the second end of the lever body 310 along a second direction. In other embodiments, the limiting structure can be a buckle, which is provided at the second end of the lever body 310 and can form a limiting engagement with the second end of the limiting hole 101 along a first direction. Of course, the limiting structure can also be other structures with limiting functions, which are not limited in this application.

[0068] In some embodiments, reference Figure 1 , Figures 3 to 6 As shown, the fulcrum structure 330 includes a rotating shaft 333, which extends along the second direction and protrudes from the rod body 310. A shaft groove 1011 is provided on the wall of the limiting hole 101, and the rotating shaft 333 is disposed within the shaft groove 1011. In this embodiment, the cooperation between the rotating shaft 333 and the shaft groove 1011 forms a lever fulcrum, ensuring stable and reliable swinging of the rod body 310. Furthermore, a limiting fit along the first direction is formed between the rotating shaft 333 and the groove wall of the shaft groove 1011, effectively preventing the rod body 310 from detaching from the first end of the limiting hole 101. With the cooperation of the limiting protrusion 320, the lever 300 will not detach from the limiting hole 101 during terminal assembly, effectively improving assembly efficiency.

[0069] In one feasible embodiment, to facilitate the assembly between the lever 300 and the mounting base 100, the lever body 310 is provided with a first through hole 311 extending in a second direction, and a rotating shaft 333 passes through the first through hole 311; wherein, the circumference of the rotating shaft 333 is provided with an elastic protrusion 3331, and the rotating shaft 333 is connected to the hole wall of the first through hole 311 through the elastic protrusion 3331. During assembly, the second end of the lever body 310 is passed through the first end of the limiting hole 101. When the end of the rotating shaft 333 protruding from the first through hole 311 is compressed, the elastic protrusion 3331 will elastically deform, so that the rotating shaft 333 moves into the first through hole 311, and then the rotating shaft 333 is suitable to enter the limiting hole 101 and be installed in the shaft groove 1011. After the rotating shaft 333 is placed in the shaft groove 1011, the elastic protrusion 3331 returns to its original deformation, so that the lever fulcrum formed between the rotating shaft 333 and the shaft groove 1011 is stable and reliable.

[0070] For example, the rotating shaft 333 is provided with a plurality of elastic protrusions 3331 spaced apart in the circumferential direction to ensure that the lever fulcrum formed between the rotating shaft 333 and the shaft groove 1011 is stable and reliable.

[0071] For example, the end of the rotating shaft 333 protruding from the first through hole 311 is provided with a first chamfered surface 3332. The first chamfered surface 3332 is disposed opposite to the limiting protrusion 320 along the first direction. During assembly, the first chamfered surface 3332 first contacts the hole wall of the limiting hole 101. Under the squeezing action of the hole wall of the limiting hole 101, the elastic protrusion 3331 undergoes elastic deformation, so that the rotating shaft 333 is suitable to enter the limiting hole 101 and be installed in the shaft groove 1011.

[0072] For example, to facilitate the disengagement of the lever 300 from the limiting hole 101, a shaft groove 1011 is provided extending through the second end of the limiting hole 101 along the first direction. A rod extends from the second end of the limiting hole 101 into the shaft groove 1011 and presses against the first chamfered surface 3332 of the rotating shaft 333, causing the rotating shaft 333 to move into the first through hole 311 and disengage from the shaft groove 1011. Pressing the second end of the rod body 310 will disengage the lever 300 from the limiting hole 101. For example, the projection of the shaft groove 1011 along the second direction can be U-shaped.

[0073] For example, along the second direction, the first end of the limiting hole 101 is provided with a second chamfered surface 1012 on the hole wall opposite to the rotating shaft 333. During assembly, the rotating shaft 333 first contacts the second chamfered surface 1012. Under the squeezing action of the second chamfered surface 1012, the elastic protrusion 3331 undergoes elastic deformation, so that the rotating shaft 333 moves into the first through hole 311, and then the rotating shaft 333 is suitable to enter the limiting hole 101 and be installed in the shaft groove 1011.

[0074] For example, while the end of the rotating shaft 333 protruding from the first through hole 311 is provided with a first chamfered surface 3332, the first end of the limiting hole 101 is provided with a second chamfered surface 1012 on the hole wall opposite to the rotating shaft 333, so as to facilitate the rotating shaft 333 to enter the limiting hole 101 and be installed in the shaft groove 1011.

[0075] In one feasible embodiment, the rod body 310 is provided with a second through hole 312 extending in a third direction. The second through hole 312 is connected to the first through hole 311. The first through hole 311 is divided by the second through hole 312 to form two first hole portions 3111, and a rotating shaft 333 is provided in each of the two first hole portions 3111. The projection of the elastic protrusion 3331 in the second direction is located within the projection range of the second through hole 312 in the second direction. The limiting hole 101 has shaft grooves 1011 on both sides of the hole wall in the second direction, and the rotating shaft 333 is located in the corresponding shaft groove 1011. In this embodiment, the design of the second through hole 312 facilitates the forming of the lever 300, and the projection of the elastic protrusion 3331 in the second direction is located within the projection range of the second through hole 312 in the second direction, so that the elastic protrusion 3331 is suitable for elastic deformation when the end of the rotating shaft 333 protruding from the first through hole 311 is compressed. In addition, the two rotating shafts 333 are arranged to make the lever fulcrum formed between the rotating shaft 333 and the shaft groove 1011 more stable and reliable.

[0076] Specifically, the first end of the limiting hole 101 is provided with a shaft groove 1011 and a second chamfered surface 1012 on both sides of the hole wall along the second direction.

[0077] For example, to further facilitate the forming of the lever 300, the surface of the elastic protrusion 3331 facing the second through hole 312 in the second direction coincides with the hole wall of the second through hole 312.

[0078] In one feasible embodiment, the second through hole 312 is stepped, including a second hole portion 3121 and a third hole portion 3122. The projection of at least one elastic protrusion 3331 along the second direction is located within the projection range of the second hole portion 3121 along the second direction; the projections of the remaining elastic protrusions 3331 along the second direction are located within the projection range of the third hole portion 3122 along the second direction. It can be understood that, along the second direction, the volume of the elastic protrusion 3331 projected into the second hole portion 3121 is smaller than the volume of the elastic protrusion 3331 projected into the third hole portion 3122. This effectively ensures a stable and reliable connection between the rotating shaft 333 and the hole wall of the first through hole 311. Furthermore, when the end of the rotating shaft 333 protruding from the first through hole 311 is compressed, the rotating shaft 333 can move into the first through hole 311 with less effort, making it easier to assemble the lever 300 and the mounting base 100. In addition, the lever 300 can be injection molded to make the second through hole 312 into a stepped shape, which can improve the molding quality of the lever 300.

[0079] For example, the rotating shaft 333 may be provided with four elastic protrusions 3331 spaced apart along the circumference, wherein the projections of two rotating shafts 333 along the second direction fall into the second hole 3121, and the projections of the other two rotating shafts 333 along the second direction fall into the third hole 3122.

[0080] For example, a groove 3123 is provided on the side wall of the second through hole 312 near the first end of the rod body 310. The groove 3123 penetrates the second through hole 312 in a third direction, which can further improve the forming quality of the lever 300.

[0081] In this embodiment, the fulcrum structure 330 may include a first arc surface 331 and a second arc surface 332, or may include a rotating shaft 333, or may include a first arc surface 331, a second arc surface 332 and a rotating shaft 333, which is not limited in this application.

[0082] In this embodiment, reference is made to Figures 7 to 9 As shown, the terminal block 210 includes a first terminal plate 211, and an elastic member 220 is located in the third direction between the first end of the rod body 310 and the first terminal plate 211.

[0083] Specifically, the elastic element 220 is bent to form a first plate portion 221, a second plate portion 222, and a third plate portion 223 connected in sequence; wherein, the projection of the bending area between the first plate portion 221 and the second plate portion 222 along a third direction at least partially overlaps with the projection of the first end of the rod body 310 along a third direction, and the third plate portion 223 abuts against the first terminal block 211; the first plate portion 221 is provided with a terminal hole 2211, and the first terminal block 211 is disposed through the terminal hole 2211. In this embodiment, when the rod body 310 is in the second position, the third plate portion 223 remains stationary under the limitation of the first terminal block 211, and the elastic potential energy between the second plate portion 222 and the third plate portion 223 causes the side of the first terminal block 211 facing away from the third plate portion 223 along a third direction to abut against or clamp the side of the terminal hole 2211 to fix the wire. When the rod body 310 swings relative to the mounting base 100 from the second position to the first position in the second direction, the first end of the rod body 310 presses against the bending area between the first plate portion 221 and the second plate portion 222. The third plate portion 223 remains stationary under the limitation of the first terminal plate 211. The second plate portion 222 bends toward the third plate portion 223, and a gap is formed between the side of the first terminal plate 211 facing away from the third plate portion 223 in the third direction and the hole wall of the wiring hole 2211, which allows the wire to pass through. The structure is stable and reliable.

[0084] Specifically, the third plate 223 and the first plate 221 can be connected by welding, bonding and bolting, or they can be fixed by the shape limitation of the mounting base 100 and the terminal block 210. This application does not limit the connection.

[0085] For example, one end of the first terminal block 211 through the terminal hole 2211 is provided with a limiting surface 2111 to form a limiting with the first plate portion 221.

[0086] For example, the end of the third plate portion 223 is disposed through the wiring hole 2211. For example, the end of the third plate portion 223 is stepped to form a limit with the first plate portion 221.

[0087] For example, the terminal block 210 further includes a second terminal block 212 disposed at an angle to the first terminal block 211. The bent area between the second plate portion 222 and the third plate portion 223 abuts against the second terminal block 212 to form a limit and stabilize the deformation of the elastic member 220. The included angle between the first terminal block 211 and the second terminal block 212 can be 45°-135°, for example, 60°, 80°, 85°, 90°, 95°, 100° or 120°.

[0088] For example, the end of the first terminal block 211 is provided with a first inclined plate portion 2112, which is inclined toward the elastic member 220. The first inclined plate portion 2112 has a guiding function to facilitate the passage of wires through the gap between the side of the first terminal block 211 facing away from the third plate portion 223 in a third direction and the wall of the wiring hole 2211. Further, the end of the first inclined plate portion 2112 is provided with an extension plate portion 2113, which extends in a first direction to the wiring channel 102 to facilitate wiring. In this embodiment, the end of the third plate portion 223 may be provided with a second inclined plate portion 2231, which abuts against the first inclined plate portion 2112 to facilitate the positioning and assembly between the elastic member 220 and the terminal block 210.
