And the distribution box 7 is generally provided with a plurality of distribution boxes so as to increase the number of electric potentials for supplying power to electric equipment and improve the utilization rate of the bus duct 3.

Moreover, the bus duct 3 and the distribution box 7 are movably connected (such as detachably connected) at the opening 34 through the conductive connecting mechanism 4, so that on one hand, the bus duct 3 and the conductive connecting mechanism 4 and the distribution box 7 and the conductive connecting mechanism 4 are easy to mount and dismount, thereby improving the convenience of mounting and dismounting the distribution box 7 and the bus duct 3, enabling the distribution box 7 to be easy to adjust in position and suitable for repeated use, and reducing the use cost and the assembly difficulty of the bus distribution device; on the other hand, the stability of the bus duct 3 and the distribution box 7 is guaranteed when the bus duct 3 is connected with the distribution box 7 through the conductive connecting mechanism 4, and the stability of the bus duct 3 when the bus duct 3 supplies power for the distribution box 7 through the conductive connecting mechanism 4 is guaranteed, so that the stability, reliability and safety of the whole structure of the bus distribution device are improved. The bus bar distribution device is also provided with a limit mechanism 8 for further improving the stability of the bus bar slot 3 when connected with the distribution box 7. Specifically, the stopper mechanism 8 and the conductive connecting mechanism 4 are each provided at a position of the distribution box 7 corresponding to the opening 34, so that the stopper mechanism 8 and the conductive connecting mechanism 4 are connected with the bus duct 3 at the opening 34. When the bus duct 3 and the distribution box 7 need to be connected, after the bus duct 3 and the distribution box 7 are connected through the conductive connecting mechanism 4, the limiting mechanism 8 which is in sliding connection with the distribution box 7 slides towards the opening 34 and stretches into the bus duct 3 to be connected with the bus duct 3, so that the stability of the bus duct 3 when connected with the distribution box 7 is further improved.

The rotary support structure 42 of the conductive connection mechanism 4 is protruding at the end of the distribution box 7 facing the opening 34, so as to avoid that the rotary support structure 42 occupies the inner space of the distribution box 7. The conductive connector 41 of the conductive connection mechanism 4 is used for connecting the rotary support structure 42 and the bus duct 3, and the conductive connector 41 is rotatably connected with the rotary support structure 42, so that the rotary support structure 42 and the distribution box 7 connected with the rotary support structure 42 are suitable for rotating relative to the conductive connector 41, thereby facilitating the operation of mounting and dismounting the distribution box 7 on the bus duct 3. When bus duct 3 passes through conductive connection mechanism 4 with distribution box 7 and is connected, rotary support structure 42 and conductive connection head 41 all are suitable for stretching into bus duct 3 inside through opening 34 for distribution box 7 and bus duct 3 direct contact, so, bus duct 3 can play the guard action to conductive connection mechanism 4, distribution box 7 and bus duct 3's junction, has further promoted bus distribution device's security, reliability.

The lower end of the second plugging portion 412 (i.e. the end of the second plugging portion 412 opposite to the Z-axis in fig. 3) is rotatably connected to the rotary support structure 42, so that the rotary support structure 42 and the distribution box 7 connected to the rotary support structure 42 are adapted to rotate relative to the conductive connector 41, thereby facilitating the operation of mounting and dismounting the distribution box 7 on and from the bus duct 3.

Alternatively, as shown in connection with fig. 3 and 4, the rotary support structure 42 comprises a fixed plate 421 adapted to be provided on the distribution box 7 and a support block 422 adapted to be detachably connected to the fixed plate 421, the mounting holes 423 penetrating the support block 422 and the fixed plate 421; the second plugging portion 412 is radially provided with a positioning structure 4121 in a protruding manner, the hole wall of the mounting hole 423 is provided with a first chute 424 axially arranged along the mounting hole 423 and a second chute 425 communicated with the first chute 424, and the positioning structure 4121 is suitable for sliding into the second chute 425 along the first chute 424; the walls of the second sliding slot 425 are adapted to limit the displacement of the positioning structure 4121 in the axial direction of the mounting hole 423 when the positioning structure 4121 slides into the second sliding slot 425.

In this embodiment, the rotary supporting structure 42 includes a fixing plate 421 and a supporting block 422, the fixing plate 421 is detachably connected with the distribution box 7 through a fastener, and the supporting block 422 is disposed at an upper end of the fixing plate 421 (i.e., the fixing plate 421 is located at one end of the Z-axis in fig. 3) and is detachably connected with the fixing plate 421 through a fastener, so as to facilitate the installation and the removal of the rotary supporting structure 42 on the distribution box 7. The supporting block 422 has a certain thickness in the axial direction of the mounting hole 423 to ensure that the second plugging portion 412 and the rotating supporting structure 42 have a sufficiently large contact area at the mounting hole 423 and ensure the stability of the connection between the second plugging portion 412 and the rotating supporting structure 42. The first sliding groove 424 is disposed on the wall of the mounting hole 423 in the axial direction (i.e., the Z-axis direction in fig. 3) of the mounting hole 423 and communicates with the mounting hole 423, the second sliding groove 425 is disposed on the wall of the mounting hole 423 and communicates with the first sliding groove 424 at the lower end of the first sliding groove 424 (i.e., the end of the first sliding groove 424 opposite to the Z-axis in fig. 3), and the second sliding groove 425 is disposed along the circumferential direction of the mounting hole 423, preferably, the first sliding groove 424 and the second sliding groove 425 are mutually perpendicular.

Alternatively, as shown in connection with fig. 1-3, the spacing mechanism 8 comprises a pull tab 81, the pull tab 81 being provided at the end of the distribution box 7 facing the opening 34 and being in sliding connection with the distribution box 7; when the bus duct 3 is connected to the distribution box 7 by the electrically conductive connection 4, the tabs 81 are adapted to slide into the interior of the bus duct 3 towards the opening 34 to limit rotation of the rotary support structure 42 relative to the electrically conductive connection 4.

The pull buckle 81 and the conductive connecting mechanism 4 are arranged at one end of the distribution box 7 facing the opening 34, and the pull buckle 81 and the conductive connecting mechanism 4 are spaced at a certain distance, so that the bus duct 3 can limit the rotation of the distribution box 7 relative to the conductive connector 41 by limiting the movement of the pull buckle 81, and the stability of the distribution box 7 and the bus duct 3 when connected through the conductive connecting mechanism 4 and the limiting mechanism 8 is ensured. Specifically, the tab 81 is slidably connected to the distribution box 7, and the sliding direction of the tab 81 is preferably parallel to the axial direction of the mounting hole 423, and after the tab 81 slides into the bus duct 3 through the opening 34, the inside of the bus bar housing 33 abuts against the tab 81 to limit the displacement of the tab 81, thereby limiting the rotation of the distribution box 7 relative to the conductive connector 41. When the distribution box 7 is mounted on the bus duct 3, the conductive connector 41 is first inserted into the opening 34 and connects the conductive connector 41 with the conductive busbar 31, then the distribution box 7 is rotated so that the length direction of the distribution box 7 is parallel to the length direction of the bus duct 3, and then the pull buckle 81 is inserted into the bus duct 3 upwards (i.e. in the positive direction of the Z-axis in fig. 1) through the opening 34 to limit the rotation of the distribution box 7 relative to the conductive connector 41, thereby completing the mounting connection between the distribution box 7 and the bus duct 3. When the distribution box 7 needs to be detached from the bus duct 3, the pull buckle 81 is pulled downwards (i.e. the Z axis is reversed in fig. 1) until the pull buckle 81 is separated from the bus duct 3, and then the distribution box 7 is rotated by a certain angle (so that the distribution box 7 is easy to be detached) and taken down, and the distribution box 7 and the conductive connecting mechanism 4 can be taken down together, so that the distribution box 7 is convenient to be installed on the bus duct 3 next time.

Optionally, the spacing mechanism 8 further comprises a resilient return structure (not shown) adapted to be provided at an end of the tab 81 remote from the opening 34 and to connect the tab 81 with the dispensing box 7.

In this embodiment, to further ensure the stability when the distribution box 7 is connected to the bus duct 3 through the conductive connection mechanism 4 and the limiting mechanism 8, the limiting mechanism 8 provides a driving force for the pull buckle 81 to slide into the bus duct 3 through an elastic reset structure (such as a spring). Specifically, the elastic reset structure is disposed at one end of the pull buckle 81 away from the opening 34 and is suitable for extending along the sliding direction of the pull buckle 81, when the pull buckle 81 is required to slide and retract downward, the pull buckle 81 is pulled downward (external force is applied to the elastic reset structure to compress the elastic reset structure), and when the pull buckle 81 is required to extend upward, the pull buckle 81 is released (external force is not applied to the elastic reset structure) so that the pull buckle 81 extends upward under the driving of the elastic reset structure. Thus, when the distribution box 7 needs to be mounted on the bus duct 3, the pull buckle 81 is pulled downwards (so as to avoid the interference of the pull buckle 81 extending upwards to the rotation of the distribution box 7), and the distribution box 7 is rotated until the length direction of the distribution box 7 is parallel to the length direction of the bus duct 3, and then the pull buckle 81 is loosened, and at this time, the pull buckle 81 extends upwards into the opening 34 and keeps stable under the driving of the elastic reset structure, so that the pull buckle 81 can be ensured to be stably positioned in the bus shell 33 without the subsequent operation of the pull buckle 81, and the stability of the distribution box 7 when being connected with the bus duct 3 is ensured. Accordingly, when the distribution box 7 needs to be detached from the bus duct 3, the pulling buckle 81 is pulled downwards until the pulling buckle 81 is separated from the bus duct 3, and then the distribution box 7 is rotated by a certain angle to remove the distribution box 7 and the conductive connecting mechanism 4.

Alternatively, as shown in connection with fig. 3, two tabs 81 are provided, with the rotary support structure 42 being located between the two tabs 81.

In this embodiment, one tab 81, the rotary support structure 42, the other tab 81 are spaced apart on the end of the distribution box 7 facing the opening 34, that is to say the rotary support structure 42 is located between the two tabs 81. Through setting up two pull buckles 81 to increase the area of contact of pull buckle 81 and bus bar housing 33, promote the steadiness when stop gear 8 and bus duct 3 are connected, further promoted the stability when distribution box 7 and bus duct 3 pass through conductive coupling mechanism 4 and stop gear 8 and connect.

Alternatively, the first plugging portion 411 and the second plugging portion 412 are respectively provided with a first cavity and a second cavity inside, and the first cavity is communicated to the inside of the distribution box 7 through the second cavity; the conductive connector 41 further includes a connector conductor 413, wherein one end of the connector conductor 413 is adapted to be disposed in the first cavity, and the other end of the connector conductor 413 is adapted to penetrate the first plugging portion 411 and extend to the slot 4111; when the conductive busbar 31 is in plug-in fit with the slot 4111, one end of the connector conductor 413, which is far away from the first cavity, is closely attached to the conductive busbar 31.

The first cavity and the second cavity are provided to facilitate internal wiring of the conductive connector 41. And the second cavity is communicated with the inside of the distribution box 7 through the matching hole 71 so as to be convenient for arranging a wire for connecting the distribution box 7 and the conductive connector 41, and the bus duct 3 is convenient for supplying power to the distribution box 7 through the conductive connecting mechanism 4. The connector conductor 413 is disposed on the first plugging portion 411 and penetrates through the first plugging portion 411, that is, the upper end of the first plugging portion 411 extends upwards to the slot 4111 for being closely disposed with the conductive busbar 31 for electrical connection when the slot 4111 is in plug-in fit with the conductive busbar 31, and the lower end of the first plugging portion 411 extends downwards into the first cavity, so that the distribution box 7 can be connected with the connector conductor 413 through corresponding wires. Thus, the stability and the reliability of the power supply of the bus duct 3 to the distribution box 7 through the conductive connecting mechanism 4 are ensured; moreover, the connector conductors 413 and the corresponding slots 4111 are adapted to clamp the conductive busbar 31, so as to enhance the connection stability of the conductive connector 41 and the conductive busbar 31, thereby enhancing the connection stability of the conductive connection mechanism 4 and the bus duct 3.
