In one embodiment, the plurality of bus bars 20 may include one or all of a first phase bus bar 21, a second phase bus bar 22, a third phase bus bar 23, and a neutral bus bar 24 and a ground bus bar 25.

In some examples, the plurality of bus bars 20 includes a first phase bus bar 21, a second phase bus bar 22, a third phase bus bar 23, a neutral bus bar 24, and a ground bus bar 25. The power distribution apparatus 1 according to the embodiment of the present application may employ a three-phase five-wire ac mode.

Thereby, three-phase power supply of the power distribution apparatus 1 can be achieved.

In addition, the electrical connection between the one end of the inner cable and the first end of the wiring unit 41 may be achieved by a plugging manner or a fastening manner, which is not particularly limited in the present application.

Optionally, the second terminal of each wiring unit 41 is electrically connected to one end of an external cable through a fastener, and the other end of the external cable is electrically connected to the electrical device.

The plurality of outlet through holes are provided in one-to-one correspondence with the plurality of wiring units 41 so that the external cables connected to the second terminals of the wiring units 41 can be extended to the outside of the housing 10 through the corresponding outlet through holes.

In some alternative examples of the present application, the other ends of the plurality of external connection cables may commonly protrude to the outside of the accommodating chamber through one outlet through hole. By the arrangement, the number of the outlet through holes on the shell 10 can be reduced, and the processing difficulty of the shell 10 is reduced.

Alternatively, as shown in fig. 3, the ratio of the pitch of two adjacent bus bar copper bars 20 in the first direction to the dimension of the bus bar copper bars 20 in the first direction is 1 to 2.

In the embodiment of the present application, the first direction may be the width direction of the power distribution device 1 (i.e., the front-rear direction in the drawing), the width direction of the bus bar 20 is parallel to the width direction of the power distribution device 1, and the dimension of the bus bar 20 in the first direction may be understood as the width dimension of the bus bar 20.

Illustratively, the ratio between the pitch of adjacent two bus bar copper bars 20 in the first direction and the width dimension of the bus bar copper bars 20 may be 1 to 2. Preferably, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the first direction and the width dimension of the bus bar copper bars 20 may be 1.5.

In some specific examples, the width dimension of the busbar 20 may be 30mm, and the pitch of two adjacent busbar 20 in the first direction may be 45mm.

It should be noted that, when the spacing between the adjacent two bus bar copper bars 20 in the first direction is too large, for example, when the ratio of the size of the bus bar copper bars 20 in the first direction is greater than 2, the plurality of bus bar copper bars 20 occupy too much space in the first direction, which results in too much space for mounting the power distribution device 1, and when the spacing between the adjacent two bus bar copper bars 20 in the first direction is too small, for example, when the ratio of the size of the bus bar copper bars 20 in the first direction is less than 1, the wiring space between the adjacent two bus bar copper bars 20 is too small, which results in inconvenience to the wiring between the bus bar copper bars 20 and the wiring module 40.

Therefore, by setting the ratio of the pitch of the adjacent two bus bar copper bars 20 in the first direction to the size of the bus bar copper bars 20 in the first direction to 1 to 2, it is not only advantageous to reduce the external dimension of the power distribution device 1, thereby reducing the occupation of the installation space, but also possible to bring convenience to the wiring between the bus bar copper bars 20 and the wiring module 40.

Alternatively, the ratio of the pitch of the adjacent two bus bar copper bars 20 in the second direction to the dimension of the bus bar copper bars 20 in the second direction is 3 to 7.

Illustratively, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the second direction and the height dimension of the bus bar copper bars 20 may be 3 to 7. Preferably, the ratio between the pitch of the adjacent two bus bar copper bars 20 in the second direction and the height dimension of the bus bar copper bars 20 may be 5.

In some specific examples, the thickness dimension of the busbar 20 may be 5mm, and the pitch of two adjacent busbar 20 in the second direction may be 25mm.

It should be noted that, in the case where the spacing between the adjacent two bus bar copper bars 20 in the second direction is too large, for example, the ratio to the size of the bus bar copper bars 20 in the second direction is larger than 7, the plurality of bus bar copper bars 20 occupy too much space in the second direction, resulting in too large a height size of the power distribution device 1 occupying too much installation space, and in the case where the spacing between the adjacent two bus bar copper bars 20 in the second direction is too small, for example, the ratio to the size of the bus bar copper bars 20 in the second direction is smaller than 3, the wiring space between the adjacent two bus bar copper bars 20 is too small, resulting in inconvenience to the wiring between the bus bar copper bars 20 and the wiring module 40.

Therefore, by setting the ratio of the pitch of the adjacent two bus bar copper bars 20 in the second direction to the size of the bus bar copper bars 20 in the second direction to 3 to 7, it is not only advantageous to reduce the external dimension of the power distribution device 1, thereby reducing the occupation of the installation space, but also possible to bring convenience to the wiring between the bus bar copper bars 20 and the wiring module 40.

In one embodiment, the busbar 20 is further provided with a second wire aperture for electrical connection with a distribution cable of the distribution device by means of a fastener.
