detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 to 3, a hot-swappable modular PDU according to the embodiment of the present invention includes a base 1 and a plurality of socket modules 2, and the base 1 is provided with a plurality of conductive busbars 11, each The socket module 2 is detachably electrically connected to the plurality of conductive bus bars 11 .

Each of the socket modules 2 includes several pins 21, and the several pins 21 protrude from the socket module 2, the number of the several pins 21 is the same as the number of the conductive bus bars 11, and the several pins 21 can be Separately plugged with the plurality of conductive bus bars 11 . It is used to realize the replacement of the single socket module 2 without replacing the whole PDU.

In the embodiment of the present utility model, the longitudinal section of the base 1 is L-shaped; the longitudinal section of the plurality of conductive bus bars 11 is U-shaped, and both ends are bent inward to form elastic pressing pieces, and the plurality of pins 11 can be It is separately inserted between the spring pressing pieces at both ends of the conductive bus bar 11 .

As shown in Figure 4, in the embodiment of the present invention, only three conductive bus bars 11 are taken as an example, the number of conductive bus bars 11 is not limited to three, and the three conductive bus bars 11 are arranged side by side along the vertical direction. An insulating partition 12 is provided on the side of the L-shaped base 1 and between two adjacent conductive bus bars 11 to prevent internal circuit short circuit. The pins 21 of the socket module 2 are located side by side in the vertical direction on one side of the socket module, and the several pins 21 are detachably inserted into the several conductive bus bars 11 along the horizontal direction. Several jacks 22 are provided on the surface for plugging in plugs and supplying power to equipment.
