It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in FIGS. 1 to 4 , the power distribution box of this embodiment includes: a box body 10 , a box cover 20 and a connector 30 . Wherein, the inside of the box body 10 has an inner cavity for accommodating electrical components, the box cover 20 is connected with the box body 10, the connector 30 is arranged on the box body 10, and the connector 30 is connected with the electrical components, for the electrical components and external electrical connections. The power distribution box in this embodiment further includes a guide rail 11 and a plurality of installation brackets 12 , the guide rail 11 is arranged in the box body 10 , and the installation brackets 12 are detachably installed on the guide rail 11 .

Applying the technical solution of this embodiment, different electrical components are installed in the inner cavity of the box body 10 through different mounting brackets 12 , and are electrically connected with the outside through the connector 30 . Because the installation bracket 12 is detachably installed on the guide rail 11 . In this way, when a new function needs to be added, it is only necessary to install the mounting bracket 12 adapted to the corresponding electrical component on the guide rail 11 , and then install the electrical component and connect it to the connector 30 . At the same time, if some functions need to be reduced, it is only necessary to disassemble the corresponding electrical components and their mounting brackets 12 . In a word, the required function can be increased or decreased by adding, reducing or replacing the mounting bracket 12 according to the requirement, thus effectively solving the problem of fixed function of the power distribution box in the prior art.

The power distribution box of this embodiment can be applied to engineering machinery such as hydraulic excavators, bulldozers, or rotary drilling rigs. Preferably, the basic common electrical components (including central controller, integrated safety relay, fuse, relay and power switch, etc.) of a construction machine such as an excavator can be installed in the power distribution box of this embodiment. In this way, when there is an electrical fault in the engineering machinery, only the box cover 20 needs to be opened, and the electrical fault location can be judged by checking the electrical components placed in the box body 10. Therefore, it is convenient to find the fault location, find out the fault in time, and then improve Efficiency in repairing faulty parts. Moreover, compared with the prior art where the electrical components are placed in different positions, and then the central integrated distribution box is fixedly connected to different positions in the construction machinery, it can reduce the fastening required for the fixed connection of the dispersed components to the main machine. The number of parts also reduces the cost accordingly.
