[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Refer to the following Figures 1 to 5 The embodiment of the present invention is further described; the universal circuit breaker terminal in the embodiment of the present invention includes a terminal body 1, which includes a plurality of wiring units 2 spliced ​​along the left and right directions, and a mounting base 10 is further provided at the left and right ends of the terminal body 1. The mounting base 10 is locked together with the wiring unit 2. When the terminal is installed, the mounting base 10 is fixed to the circuit breaker.

[0025] Reference Figure 3 and Figure 4As shown, each wiring unit 2 includes a shell 21, an upper wiring structure 1 22 and a lower wiring structure 1 23 provided on the front side of the shell 21, and an upper wiring structure 2 31 and a lower wiring structure 2 32 provided on the rear side of the shell 21. The upper wiring structure 1 22 and the lower wiring structure 1 23 are electrically connected to the upper wiring structure 2 31 and the lower wiring structure 2 32 respectively. Specifically, the upper wiring structure 1 22 and the upper wiring structure 2 31 can be connected as one, or the upper wiring structure 1 22 and the upper wiring structure 2 31 can be connected through a soft wire; similarly, the lower wiring structure 1 23 and the lower wiring structure 2 32 can be connected as one, or the lower wiring structure 1 23 and the lower wiring structure 2 32 can be connected through a soft wire.

[0026] Preferably, the upper wiring structure 22 and the lower wiring structure 23 in each wiring unit 2 are staggered in the left-right direction and the front-back direction. This can increase the distance between the upper wiring structure 22 and the lower wiring structure 23 in the same wiring unit 2, so that when the line end is connected to the upper wiring structure 22 and the lower wiring structure 23, the operation space during wiring is larger, which can reduce interference and thus help improve wiring efficiency. Moreover, the upper wiring structure 22 and the lower wiring structure 23 have a relatively long insulation distance, which can avoid the problem of short circuit caused by the close distance between the two.

[0027] As another embodiment or as an optimization based on the above embodiment, the upper wiring structure 2 31 and the lower wiring structure 2 32 in each wiring unit 2 are staggered in the left-right direction and the front-back direction. This arrangement can increase the distance between the upper wiring structure 2 31 and the lower wiring structure 2 32 in the same wiring unit 2, thereby reducing interference when the wire ends are connected to the upper wiring structure 2 31 and the lower wiring structure 2 32, thereby helping to improve wiring efficiency. In addition, the upper wiring structure 2 31 and the lower wiring structure 2 32 have a relatively long insulation distance, which can avoid the problem of short circuit caused by the close distance between the two.

[0028] In this embodiment, the upper wiring structure 1 22 and the lower wiring structure 1 23 are configured as plugs, and the upper wiring structure 2 31 and the lower wiring structure 2 32 are configured as screw terminal assemblies. As a variation, in actual operation, the upper wiring structure 1 22 and the lower wiring structure 1 23 can be configured as screw terminal assemblies, and the upper wiring structure 2 31 and the lower wiring structure 2 32 can be plugs; or the upper wiring structure 1 22 and the lower wiring structure 1 23 can be configured as screw terminal assemblies, and the upper wiring structure 2 31 and the lower wiring structure 2 32 can be screw terminal assemblies; or the upper wiring structure 1 22 and the lower wiring structure 1 23 can be plugs, and the upper wiring structure 2 31 and the lower wiring structure 2 32 can be plugs. The wiring method can be flexibly set according to specific needs; the plug can be directly connected to the socket at the end of the wire, and the screw terminal assembly can connect the wire by tightening the screw.

[0029] Exemplarily, a clamping foot is provided on the inserting piece, a clamping slot is provided on the side of the shell 21, and a pressing block is provided on the other shell. The clamping foot is engaged with the clamping slot and is pressed against the inserting piece by the pressing block to fix the inserting piece.

[0030] The screw terminal assembly includes a terminal lug 11 and a crimping screw. The crimping screw is screwed to the terminal lug 11, and the wire end can be pressed against the terminal lug 11 by the crimping screw to complete the wiring; or a wiring frame is sleeved on the terminal lug 11, and the crimping screw is screwed on the wiring frame. When wiring, the wire end is inserted into the wiring frame and the wire is pressed against the terminal lug 11 by tightening the crimping screw.

[0031] Reference Figure 3 and Figure 4 In the left-right direction, a protrusion 41 is provided on one side of the housing 21, and a corresponding insertion hole 42 is provided on the other side. When two adjacent wiring units 2 are spliced ​​together, the protrusion 41 on the housing 21 of one wiring unit 2 is plugged into the insertion hole 42 on the housing 21 of the other wiring unit 2, and the plugging direction is the left-right direction. The cooperation between the protrusion 41 and the insertion hole 42 can strengthen the connection between the wiring units 2, thereby enhancing the torsional deformation resistance of the terminal body 1. Preferably, the number of the protrusions 41 is set to two or more, and the number of corresponding insertion holes 42 is set to two or more.

[0032] Reference Figures 1 to 5 In order to further enhance the insulation performance, it is preferred that a front upper partition 5 and a front lower partition 6 are protrudingly provided on the front side of the shell 21, and the two adjacent upper wiring structures 22 are separated by the front upper partition 5, and the two adjacent lower wiring structures 23 are separated by the front lower partition 6; and further, a rear upper partition 51 and a rear lower partition 61 are protrudingly provided on the rear side of the shell 21, and the adjacent upper wiring structures 2 31 in the two adjacent wiring units 2 are separated by the rear upper partition 51, and the adjacent lower wiring structures 2 32 are separated by the rear lower partition 61.

[0033] Preferably, a step structure 1 8 is formed on the front side of the shell 21 between the upper wiring structure 1 22 and the lower wiring structure 1 23, and a step structure 2 9 is formed on the rear side of the shell 21 between the upper wiring structure 2 31 and the lower wiring structure 2 32. The setting of the step structure 1 8 and the step structure 2 9 plays a spacing role, which can further improve the insulation performance. In actual operation, only one of the step structure 1 8 and the step structure 2 9 can be set.

[0034] Reference Figure 2 and Figure 5As shown, a protective cover 7 is installed on the upper part of the terminal body 1, and the protective cover 7 can be fixed to the terminal body 1 by snapping or screws. The protective cover 7 blocks the upper wiring structure 1 22. The shielding effect of the protective cover 7 can enhance the protection performance. As a modified implementation scheme, in actual operation, the protective cover 7 can be set to block the upper wiring structure 2 31, or the protective cover 7 can block the upper wiring structure 1 22 and the upper wiring structure 2 31.
