Abstract

The utility model belongs to the field of fuel cell accessories, and discloses a quick-plug type fuel cell distribution box. The distribution box is composed of an upper cover and a base. A supporting surface for placing a power distribution and control element is arranged in the base, and the bottom of the base is connected with a fixing pad; a sealing ring is arranged at the edge of the top of the base; the upper cover is arranged on the base in a covering mode. The fuel cell distribution box disclosed by the utility model is low in cost, small in size, low in failure rate and high in waterproof grade, the relay, the fuse and the wire harness terminal are fixed in the distribution box through a pure structure, and a connector is not needed to fix the wire harness terminal, so that the cost can be effectively saved; as a control chip and a circuit board are not arranged in the power distribution box, the internal space can be effectively saved, the failure rate is reduced, and the waterproof level of the waterproof plug and the sealing plug is also up to IP67.
