[0038] Terminal blocks are used to connect cables to electrical equipment. Terminal blocks are typically installed inside electrical equipment and fixed to the equipment, connecting external cables to the cables within. However, currently, when users connect external cables to terminal blocks, the terminal block base is integrally cast, and the incoming and outgoing terminals cannot be disassembled. Therefore, the cables on both ends of the terminal block must be wired inside the cabinet. The internal cables connected to the terminal blocks are pre-installed before the cabinet leaves the factory, while external cables must be connected after the cabinet is installed. Terminal blocks are typically fixed to the back panel of the cabinet. However, electrical cabinets are typically deep (400mm to 1000mm) or installed at a high height (1.8m from the bottom edge to the ground), and they also require numerous internal wiring. Therefore, wiring after the cabinet is installed is inconvenient and poses a safety hazard.

[0039] In order to improve the problem of inconvenient connection between external cables and wiring terminals in an electrical cabinet, the present application proposes a wiring terminal.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 3 as well as Figure 10 In one embodiment of the present application, the connection terminal includes an incoming terminal 100 and a receiving terminal 200. The incoming terminal 100 includes a first base 110 and a first conductive member 120 provided on the first base 110; the receiving terminal 200 includes a second base 210 and a second conductive member 220 provided on the second base 210; the first base 110 and the second base 210 are detachably connected, and the first conductive member 120 and the second conductive member 220 are electrically connected.

[0041] The incoming terminal 100 refers to a terminal for connecting to an external cable. The incoming terminal 100 includes a first base 110, which serves as a basic component for setting the first conductive member 120 and also provides an insulating basis for the user to hold the incoming terminal 100. The first base 110 is a base made of an insulating material, such as plastic or rubber, as long as it can provide a good insulating effect. The incoming terminal 100 also includes a first conductive member 120. By arranging the first conductive member 120 on the first base 110, the integrity of the incoming terminal 100 is ensured. When the first conductive member 120 is arranged on the first base 110, one end of the first base 110 can allow part of the first conductive member 120 to extend, that is, the other part of the first conductive member 120 is located on the first base 110 to be insulated and wrapped by the first base 110. In order to achieve the effect of conductive connection between the external cable and the first conductive member 120, an interface may be provided at the end of the first base 110 where the first conductive member 120 is not passed through, and the interface is used for inserting the external cable. The connector of the external cable inserted into the interface may directly contact the portion of the first conductive member 120 extending into the first base 110 to achieve the effect of conductive connection. When the portion of the first conductive member 120 extending into the first base 110 contacts the external cable, the portion of the first conductive member 120 extending into the first base 110 may form a socket structure, so that the external cable can pass through the interface of the first base 110 and the socket of the first conductive member 120 in turn, thereby achieving the effect of contact between the external cable and the inner wall of the socket of the first conductive member 120, thereby ensuring that the external cable can achieve a good conductive connection with the first conductive member 120. Alternatively, one end of the first conductive member 120 may be directly bonded or welded to the surface of the first base 110, with the other end extending away from the first base 110. The first conductive member 120 may include a connection structure for electrically connecting to an external cable, thereby enabling the external cable to be directly electrically connected to the first conductive member 120 without having to pass through the first base 110. Furthermore, the provision of the first conductive member 120 ensures a good electrical connection between the incoming terminal 100 and the receiving terminal 200. Specifically, the first conductive member 120 may be a conductive column, a conductive needle, or a conductive hole; or the first conductive member 120 may have a partially needle-like or columnar structure and another partially a hole-like structure. When the first conductive member 120 is disposed on the first base 110 , if the first conductive member 120 has a hole-like structure, the first conductive member 120 can be entirely disposed within the first base 110 . When the first conductive member 120 has a needle-like structure or a columnar structure, the first conductive member 120 can at least partially extend out of the first base 110 to facilitate electrical connection with the second conductive member 220 of the power receiving terminal 200 .

[0042] The power receiving terminal 200 is a terminal used to connect to cables within an electrical cabinet. The power receiving terminal 200 includes a second base 210, which serves as the foundation for mounting the second conductive member 220 and also provides an insulating base for the user to grip the power receiving terminal 200. The second base 210 is made of an insulating material, such as plastic or rubber, as long as it provides good insulation. The power receiving terminal 200 also includes the second conductive member 220. By placing the second conductive member 220 on the second base 210, the integrity of the power receiving terminal 200 is ensured. Furthermore, the second conductive member 220 ensures a good electrical connection between the power receiving terminal 200 and the first conductive member 120 of the incoming terminal 100. Similarly, the second conductive member 220 can be a conductive column, a conductive pin, or a conductive hole; or, alternatively, the second conductive member 220 can be partially needle-shaped or columnar, while another portion is a hole. When the second conductive member 220 is disposed on the second base 210, if the second conductive member 220 has a hole-like structure, the second conductive member 220 can be entirely disposed within the second base 210. When the second conductive member 220 has a needle-like or column-like structure, the second conductive member 220 can at least partially extend from the second base 210 to facilitate electrical connection with the first conductive member 120 of the incoming terminal 100. When the second conductive member 220 is disposed on the second base 210, one end of the second base 210 can allow a portion of the second conductive member 220 to extend, that is, another portion of the second conductive member 220 is located on the second base 210 and is insulated and enclosed by the second base 210. Alternatively, the second conductive member 220 can be entirely enclosed by the second base 210. For example, to facilitate electrical connection between the first conductive member 120 and the second conductive member 220 after the first base 110 and the second base 210 are connected, the second conductive member 220 may be formed with a docking port for insertion of the first conductive member 120, based on the solution where the first conductive member 120 at least partially extends outside the first base 110. To achieve better insulation, the second conductive member 220 may be completely enclosed by the second base 210, that is, the second conductive member 220 is disposed within the second base 210, and the second base 210 has a first escape port for insertion of the first conductive member 120. The end of the second conductive member 220 proximal to the first conductive member 120 forms a docking port and is located within the second base 210. To achieve an electrically conductive connection between the cables within the electrical cabinet and the second conductive member 220, the end of the second conductive member 220 distal to the first conductive member 120 may also extend outside the second base 210 to achieve an electrically conductive connection with the cables within the electrical cabinet.Alternatively, the portion of the second conductive member 220 away from one end of the first conductive member 120 may be formed with a socket structure. Similarly, the end of the second base 210 away from the first base 110 may be provided with a avoidance opening, and the end of the second conductive member 220 formed with the socket is also located inside the second base 210, so that the cables in the electrical cabinet can pass through the second avoidance opening of the second base 210 and the socket structure of the second conductive member 220 in sequence, thereby achieving the effect of the cables in the electrical cabinet contacting the inner wall of the socket of the second conductive member 220, thereby ensuring that the cables in the electrical cabinet can achieve a good conductive connection with the second conductive member 220.

[0043] When the first base 110 and the second base 210 are detachably connected, connection methods such as screw connection, snap connection 130 connection, plug-in connection, and magnetic connection can be used, as long as the first base 110 can be removed from the second base 210 and the first base 110 drives the first conductive part 120 to separate from the second conductive part 220 of the second base 210.

[0044] The technical solution of the present application makes the incoming terminal 100 and the receiving terminal 200 detachable by detachably connecting the first base 110 of the incoming terminal 100 with the second base 210 of the receiving terminal 200. This makes the incoming terminal 100 and the receiving terminal 200 detachable, thereby facilitating the fixing of the receiving terminal 200 within the electrical cabinet. After the terminal block is removed from the receiving terminal 200, it can be electrically connected to an external cable outside the electrical cabinet, thereby reducing the need to connect external cables within the electrical cabinet, thereby improving the convenience of connecting external cables to the terminal block and reducing personal safety hazards. In addition, by providing the first conductive member 120 on the first base 110 and the second conductive member 220 on the second base 210, and by connecting the first base 110 and the second base 210, the first conductive member 120 and the second conductive member 220 are electrically connected, thereby achieving the effect of electrically connecting the incoming terminal 100 and the receiving terminal 200, thereby achieving the effect of electrically connecting the external cable to the cable in the electrical cabinet for electrically connecting to the receiving terminal 200.

[0045] Please refer to Figures 1 to 8 In some embodiments of the present application, the first base 110 is snap-connected with the second base 210 .

[0046] By snapping the first base 110 and the second base 210 together, the assembly and disassembly of the first base 110 and the second base 210 becomes more convenient. In addition, such an arrangement also makes the first base 110 and the second base 210 more stable after being connected.

[0047] Specifically, when the first base 110 and the second base 210 are snap-fitted together, the snap buckle 130 and the slot 211 may be engaged with each other, or an interference fit may be used to achieve the snap-fit ​​effect.

[0048] Please refer to Figures 1 to 8 In some embodiments of the present application, one of the first base 110 and the second base 210 is provided with a buckle 130 , and the other one is provided with a slot 211 , and the buckle 130 is snapped into the slot 211 .

[0049] By providing a buckle 130 on one of the first base 110 and the second base 210 and providing a slot 211 on the other, and snapping the buckle 130 into the slot 211 , a more stable snap connection between the first base 110 and the second base 210 is ensured.

[0050] Specifically, the first base 110 is provided with a buckle 130 , and the second base 210 is provided with a slot 211 ; or the first base 110 is provided with a slot 211 , and the second base 210 is provided with a buckle 130 .

[0051] Please refer to Figures 1 to 8 Furthermore, the buckle 130 includes an extension arm 131, a buckle body 133 and an extension arm 132; one end of the extension arm 131 is connected to one of the first base 110 and the second base 120, and the other end is connected to the buckle body 133 through the extension arm 132; one of the first base 110 and the second base 210 having a card slot 211 is also provided with a rotating track 212, a socket 213 and a connecting space, the card slot 211 is arranged at one end close to the rotating track 212 and is spaced apart from the rotating track 212; the rotating track 212 is provided with a socket 213 at one end away from the card slot 211, the socket 213 is connected to the rotating track 212, and the connecting space connects the socket 213 and the card slot 211.

[0052] Specifically, when the first base 110 is provided with a buckle 130 and the second base 210 is provided with a slot 211, the second base 210 is provided with a rotating track 212, a slot 211 and a socket 213; when the second base 210 is provided with a buckle 130 and the first base 110 is provided with a slot 211, the first base 110 is also provided with a rotating track 212, a slot 211 and a socket 213. Taking the example of a first base 110 having a buckle 130 and a second base 210 having a slot 211, a rotating track 212, and an insertion hole 213 as an example, it is understood that during installation, the user places the first base 110 close to the second base 210 and inserts the buckle 130 into the insertion hole 213 through the end connected to the rotating track 212 and the insertion hole 213. Specifically, the extension arm 131 of the buckle 130 is inserted into the rotating track 212, and the extension arm 132 and the buckle body 133 of the buckle 130 are inserted into the insertion hole 213. The extension arm 131 of the buckle 130 then rotates along the rotating track 212, while the extension arm 132 and the buckle body 133 of the buckle 130 move within the connected space within the second base 210 toward the end adjacent to the slot 211 along with the movement of the extension arm 131. When the buckle 130 moves to the end of the rotating track 212 away from the insertion hole 213, and the buckle body 133 of the buckle 130 is aligned with the slot 211, the buckle body 133 of the buckle 130 can be engaged with the slot 211. At this time, the extension arm 131 is still located in the rotating track 212. Because the slot 211 and the rotating track 212 are spaced apart from each other, that is, there is a stop wall between the slot 211 and the rotating track 212, the stop wall can stop the extension arm 132 between the extension arm 131 and the buckle body 133. Therefore, after the buckle 130 is locked in the slot 211, it will not easily fall out of the direction close to the end of the extension arm 131 away from the buckle body 133 through the rotating track 212. On the contrary, when it is necessary to separate the first base 110 from the second base 210, the buckle 130 can be moved in the direction from the end of the extension arm 131 close to the first base 110 to the end away from the first base 110 to disengage the slot 211, and then the buckle 130 and the first base 110 are rotated in the opposite direction, so that the buckle 130 passes through the connecting space and moves along the trajectory of the rotating track 212 to the socket 213. At this time, the socket 213 can provide an escape space for the extension arm 132 of the buckle 130 and the buckle body 133 of the buckle 130 to separate from the second base 210. Therefore, the buckle 130 and the first base 110 can be moved in the direction from the end of the extension arm 131 close to the first base 110 to the end of the extension arm 131 away from the first base 110, so that the first base 110 and the second base 210 can be separated.

[0053] By setting a socket 213 at one end of the rotating track 212 away from the card slot 211, and the socket 213 is connected to the rotating track 212, it is convenient for the buckle 130 to be inserted into the second base 210 through the socket 213. By setting the card slot 211 close to one end of the rotating track 212 and spaced apart from the rotating track 212, when the buckle 130 is inserted into the socket 213, it can move along the trajectory of the rotating track 212 to the position corresponding to the card slot 211, so that the buckle 130 can be engaged with the card slot 211, and the buckle 130 can be prevented from being detached from the position of the rotating track 212 close to the card slot 211, thereby achieving a more stable engagement effect between the buckle 130 and the card slot 211.

[0054] Furthermore, if Figure 1 As shown, one of the first base 110 and the second base 210 is further connected to an elastic insulating pad 140 , and the elastic insulating pad 140 is clamped between the first base 110 and the second base 210 .

[0055] By clamping the elastic insulating pad 140 between the first base 110 and the second base 210, the risk of the first conductive member 120 and / or the second conductive member 220 being exposed can be reduced, thereby improving the safety of the incoming terminal 100 and the receiving terminal 200 after connection. In addition, in combination with the above solution, when the first base 110 and the second base 210 are brought close together and snapped together, the buckle 130 squeezes the elastic insulating pad 140 when inserted into the slot 211. After insertion, when the buckle 130 is rotated along the trajectory of the rotating track 212 until it is opposite to the slot 211, the elastic insulating pad 140 rebounds, allowing the buckle 130 to automatically and securely snap into the slot 211, thereby improving the stability of the connection between the first base 110 and the second base 210. When the first base 110 and the second base 210 need to be disassembled, the first base 110 or the second base 210 can be pressed so that the elastic insulating pad 140 is squeezed again, so that the buckle 130 disengages from the slot 211, and then moves in the opposite direction along the trajectory of the rotating track 212 to the position corresponding to the socket 213. Under the elastic force of the elastic insulating pad 140, the buckle 130 disengages from the socket 213, thereby achieving the effect of separating the first base 110 from the second base 210.

[0056] Please refer to Figure 1 and Figure 8 In some embodiments of the present application, one of the first conductive member 120 and the second conductive member 220 is provided with a conductive hole, and the other one includes a conductive insert, which is inserted into the conductive hole and conductively connected to the inner wall of the conductive hole.

[0057] Specifically, the first conductive member 120 may have a conductive hole and the second conductive member 220 may include a conductive insert; or the second conductive member 220 may have a conductive hole and the first conductive member 120 may include a conductive insert. It should be noted that a conductive hole refers to a hole structure whose inner wall is made of a conductive material.

[0058] By inserting the conductive insert into the conductive hole and conductively connecting it to the inner wall of the conductive hole, the first conductive member 120 and the second conductive member 220 are connected easily and the conductive effect between the first conductive member 120 and the second conductive member 220 is improved.

[0059] In addition, the clamping direction of the first base 110 and the second base 210 can also be set to the plugging direction of the first conductive member 120 and the second conductive member 220. In this way, while the first base 110 and the second base 210 are clamped together, the first conductive member 120 and the second conductive member 220 can also be conductively connected. Therefore, the connection efficiency between the two is higher while ensuring the conductive connection between the incoming terminal 100 and the receiving terminal 200.

[0060] like Figure 1 As shown, further, the conductive insert is an elastomer, and the conductive insert can be elastically deformed in the radial direction.

[0061] By setting the conductive insert as an elastomer, the conductive insert can undergo elastic deformation in the radial direction, so that after the conductive insert is inserted into the conductive hole, it can press against the inner wall of the conductive hole under the action of its elastic force, thereby achieving a good conductive connection effect between the conductive insert and the inner wall of the conductive hole.

[0062] like Figure 1 As shown, in some embodiments of the present application, the conductive insert has an expansion joint 121 , and an extension direction of the expansion joint 121 is parallel to or formed at an acute angle to an extension direction of the conductive insert.

[0063] By providing an expansion gap 121 on the conductive insert, with the expansion gap 121 arranged parallel to or at an acute angle to the extension direction of the conductive insert, the conductive insert can be deformed in its radial direction, thereby changing the size of the expansion gap 121. Due to the presence of the expansion gap 121, the conductive insert is squeezed when inserted into the conductive hole, and the size of the expansion gap 121 is reduced, allowing the conductive insert to be inserted into the conductive hole. After the conductive insert is inserted into the conductive hole, the metal conductive insert generates a reaction force to return to its original shape. This force ensures that the expansion gap 121 of the conductive insert is open, ensuring that the conductive insert remains tightly connected to the hole wall. This ensures that the conductive insert can be inserted into the conductive hole and that a reliable electrical connection is maintained between the conductive insert and the hole.

[0064] Of course, it is understandable that in order to make the conductive insert have elastic force in its radial direction, the conductive insert may include two movable movable arms arranged opposite to each other in the radial direction of the conductive hole, and an elastic part, such as a spring or a spring, may be connected between the two opposite movable arms. In a natural state, the distance between the two movable arms is slightly larger than the diameter of the conductive hole. The user can squeeze the two movable arms in advance, and the elastic part is compressed and deformed. When the elastic part is compressed and deformed, the distance between the two movable arms becomes smaller, thereby ensuring that the conductive insert composed of the two movable arms and the elastic part is inserted into the conductive hole. When the two movable arms are inserted into the conductive hole, the user lets go, and the two movable arms are pressed against the inner wall of the conductive hole under the action of the rebound force of the elastic part. Such a setting can not only ensure that the conductive insert can be inserted into the conductive hole, but also ensure a reliable electrical connection between the two.

[0065] Please refer to Figures 1 to 9 In some embodiments of the present application, a splicing lock buckle 230 and a splicing slot 240 are respectively provided on opposite sides of the second base 210, and the splicing lock buckle 230 is adapted to the splicing slot 240.

[0066] By providing a splicing latch 230 and a splicing slot 240 on opposite sides of the second base 210, and by aligning the splicing latch 230 with the splicing slot 240, two, three, or more power receiving terminals 200 can be spliced ​​together in sequence, thereby achieving a stable connection between at least two power receiving terminals 200 and providing greater flexibility in the number of power receiving terminals 200 that can be spliced ​​together. Furthermore, by aligning the splicing latch 230 with the splicing slot 240, the walls of the splicing slot 240 in one power receiving terminal 200 and the mating splicing latch 230 can be mutually restrained, thereby achieving a mutually restrained position between at least two connected power receiving terminals 200.

[0067] Specifically, in order to ensure that the splicing lock buckle 230 is not easy to fall out of the splicing card slot 240 after being adapted to the splicing card slot 240, the splicing lock buckle 230 can be interference fit with the splicing card slot 240. For example, the dimensions of the splicing lock buckle 230 at all locations during the process of inserting into the splicing card slot 240 are larger than the dimensions of the splicing card slot 240. After the splicing lock buckle 230 is inserted into the splicing card slot 240, it can be pressed against the wall of the splicing card slot 240, thereby increasing the friction between the splicing lock buckle 230 and the splicing card slot 240. The user needs to use greater force to separate the two second bases 210 that are adapted and connected to the splicing card slot 240 through the splicing lock buckle 230. Alternatively, the splicing lock buckle 230 is wedge-shaped in the direction of insertion into the splicing card slot 240, that is, the size of the end of the splicing lock buckle 230 that is first inserted into the splicing card slot 240 is smaller, and the size of the end of the splicing lock buckle 230 that is later inserted into the splicing card slot 240 is larger, and the size of this end is larger than the size of the splicing card slot 240. In the process of inserting the splicing lock buckle 230 into the splicing card slot 240, the splicing lock buckle 230 and the splicing card slot 240 are gradually pressed together, thereby also increasing the friction between the splicing lock buckle 230 and the splicing card slot 240. The user needs more force to separate the two second bases 210 that are adapted and connected to the splicing card slot 240 through the splicing lock buckle 230.

[0068] like Figure 8 As shown, in some embodiments of the present application, the splicing lock buckle 230 includes a first splicing section 231 and a second splicing section 232 , and the second splicing section 232 is arranged at an angle to the first splicing section 231 .

[0069] By setting the first splicing section 231 and the second splicing section 232 at an angle, the first splicing section 231 can limit the second base 210 that matches it in a direction perpendicular to its length, and the second splicing section 232 can limit the second base 210 that matches it in a direction perpendicular to the length of the second splicing section 232. That is, the splicing lock 230 set in this way can limit the second base 210 in at least two different directions, thereby ensuring that at least two second bases 210 have a relatively stable connection effect after splicing.

[0070] To facilitate the fitting and engaging of the splicing lock buckle 230 with the splicing slot 240, the splicing slot 240 may extend through two opposing surfaces of the second base 210 along the extension direction of the first splicing section 231. Thus, when the splicing lock buckle 230 and the splicing slot 240 are assembled, the splicing lock buckle 230 may be inserted into the splicing slot 240 along the extension direction of its first splicing section 231, with at least the first splicing section 231 being interference-fitted with the splicing lock buckle 230. Alternatively, the splicing slot 240 may extend through two opposing surfaces of the second base 210 along the extension direction of the second splicing section 232. Thus, when the splicing lock buckle 230 and the splicing slot 240 are assembled, the splicing lock buckle 230 may be inserted into the splicing slot 240 along the extension direction of its second splicing section 232, with at least the first splicing section 231 being interference-fitted with the splicing lock buckle 230. Such a configuration ensures that the user needs to exert greater force to separate the two second bases 210 that are adapted and engaged with the splicing lock buckle 230 and the splicing slot 240 .

[0071] Specifically, the first splicing section 231 and the second splicing section 232 can be arranged perpendicularly. For example, the first splicing section 231 and the second splicing section 232 can form a structure similar to a T-shape or a 7-shape. Of course, the first splicing section 231 and the second splicing section 232 can also be arranged at an acute angle or an obtuse angle. In addition to including the first splicing section 231 and the second splicing section 232 described above, the splicing lock 230 can also include a third splicing section, a fourth splicing section, etc. For example, the splicing lock 230 can be in a Z-shape, N-shape, or M-shape.

[0072] like Figure 8 As shown, further, at least two splicing lock buckles 230 are provided, and the first splicing sections 231 of the at least two splicing lock buckles 230 are arranged in parallel, and the second splicing sections 232 are arranged symmetrically.

[0073] With such a configuration, the two splicing lock buckles 230 can restrict each other, thereby further improving the connection stability of the two power receiving terminals 200 spliced ​​together.

[0074] Please refer to Figures 1 to 5 In some embodiments of the present application, the first base 110 has a through channel 150, which passes through the end surface of the first base 110 away from the second base 210 and the end surface close to the second base 210 for inserting an external cable; the first conductive member 120 at least partially extends into the through channel 150, and a conductive connector 122 is also formed on the end of the first conductive member 120 extending into the through channel 150 for conductive connection with the external cable.

[0075] The conductive connector 122 refers to an interface or a conductive sheet that can conduct electricity, etc., that is, after the external cable is connected to the conductive connector 122, it can achieve a conductive connection when it contacts the wall surface of the conductive connector 122. By extending one end of the first conductive member 120 into the through channel 150 of the first base 110 and forming the conductive connector 122, the external cable can be electrically connected to the conductive connector 122, thereby achieving the effect of electrically connecting the external cable to the first conductive member 120, thereby improving the stability and effectiveness of the electrical connection between the external cable and the first conductive member 120 after being connected to the incoming terminal 100. In addition, such a configuration allows the conductive connector 122 of the first conductive member 120 to be located inside the first base 110, so that the first base 110 can wrap around the outer wall of the conductive connector 122 of the first conductive member 120 to achieve a good insulation effect, reducing the risk of electric shock to the user when inserting the external cable into the conductive connector 122.

[0076] Please refer to Figure 1 and Figure 5 Furthermore, the conductive connector 122 is a conductive sheet, and an adjustable crimping piece 160 is movably provided in the through-channel 150. The adjustable crimping piece 160 is arranged opposite to the conductive sheet and can move in the direction of approaching and away from the conductive sheet so that the external cable can be pressed against the conductive sheet.

[0077] When an external cable is conductively connected to the conductive connector 122, a straight-through bare wire can be inserted into the through-channel 150, with the conductive connector 122 abutting against one side of the adjustable crimping member 160. Alternatively, a flat terminal (such as an OT terminal or a pin terminal) can be connected to the conductive connector 122. By configuring the conductive connector 122 as a conductive sheet, and disposing the adjustable crimping member 160 in the through-channel 150, the adjustable crimping member 160 is disposed opposite the conductive sheet and can move in directions close to and away from the conductive sheet. When the adjustable crimping member 160 moves, the distance between the conductive connector 122 and the adjustable crimping member 160 can be adjusted, thereby enabling the through-channel 150 to accommodate external cables or external connectors of different sizes for connection thereto, thereby improving the compatibility of the incoming terminal 100.

[0078] Specifically, the adjustable crimping member 160 can be an elastic member, such as rubber or a component with a spring, which can expand and contract in the height direction of the conductive connector 122, thereby changing the height dimension of the through-channel 150. Alternatively, the adjustable crimping member 160 can be a component that can move within the through-channel 150, specifically a component that can move in the height direction of the through-channel 150. The adjustable crimping member 160 can be driven by a driving member when it moves in the height direction of the through-channel 150, for example, by adjusting the length of the screw connection between the bolt and the first base 110 or by a button.

[0079] like Figure 1 As shown, in some embodiments of the present application, the adjustable crimping member 160 is slidably disposed in the through channel 150 and can move along the height direction of the conductive connector 122 .

[0080] By sliding the adjustable crimping piece 160 in the through channel 150 and allowing it to move along the height direction of the conductive connector 122, the position of the adjustable crimping piece 160 can be flexibly adjusted to a higher position, thereby facilitating the insertion of the connector of the external cable into the conductive connector 122; when the external cable is connected to the conductive connector 122, the position of the adjustable crimping piece 160 is adjusted to be lowered so that it can press the part of the external cable inserted into the conductive connector 122, thereby ensuring a good electrical connection between the external cable and the conductive connector 122.

[0081] The present application also proposes a terminal assembly, which includes at least two connecting terminals. The specific structure of the connecting terminal refers to the above-mentioned embodiment. Since the present connecting terminal adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0082] In some embodiments of this application, please refer to Figure 1 and Figure 10 Based on the solution that one of the first base 110 and the second base 210 in the above-mentioned terminal block is provided with a clip 130, the other one is provided with a slot 211, and the clip 130 is snapped into the slot 211, further, the shapes of the clips 130 of at least two terminal blocks are different.

[0083] By setting the shapes of the clips 130 in the two terminals to be different, it is easy to distinguish that the two terminals are connected to different cables, for example, one is connected to the neutral wire and the other is connected to the live wire, avoiding the risk of difficulty in distinguishing which terminal is connected to the live wire and which terminal is connected to the neutral wire due to the two clips 130 having the same shape, thereby avoiding the risk of short-circuiting the live wire and the neutral wire.

[0084] Specifically, when the shapes of the buckles 130 of at least two connection terminals are different, the cross-sectional shape of the buckle 130 of the connection terminal connected to the live wire can be set to a rectangular shape (please refer to the specific Figure 1 As shown), the cross-sectional shape of the buckle 130 of the terminal block connected to the neutral line is set to be semicircular, etc. (please refer to Figure 10 shown).

[0085] In some embodiments of the present application, based on the first base 110 having a through channel 150, the through channel 150 passes through the end surface of the first base 110 away from the second base 210 and the end surface close to the second base 210 for insertion of an external cable; the first conductive member 120 at least partially extends into the through channel 150, and the end of the first conductive member 120 extending into the through channel 150 is also formed with a conductive connector 122 for conductive connection with an external cable. Further, the width dimensions of the conductive connectors 122 of at least two terminal blocks are different.

[0086] In some cases, the live wire diameter is larger than the neutral wire diameter, and the width of the terminal connected to the live wire is larger than the width of the terminal connected to the neutral wire. In this embodiment, by making the conductive connectors 122 of at least two terminal blocks have different widths, the two conductive connectors 122 of different widths are adapted to terminals of different widths, that is, to the terminals corresponding to the live wire and the neutral wire respectively. This prevents the live wire terminal from being inserted into the conductive connector 122 of the corresponding neutral wire terminal, thereby avoiding the risk of incorrectly connecting the live and neutral wires.

[0087] The present application also proposes an electrical cabinet, which includes a wiring terminal. The specific structure of the wiring terminal refers to the above-mentioned embodiment. Since the electrical cabinet adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

Any equivalent structural transformation made using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
