A high-sealing integrated distribution box, including a distribution box shell, a sealing rubber strip fixedly connected to one side of the box door away from the hinge, a top pressure block fixedly connected to the upper surface of the box door, and a lighting lamp automatic switch device fixed to the top side of the distribution box shell A lighting lamp is fixedly connected to the left side of the lighting lamp automatic switch device. The present utility model relates to the field of distribution boxes. The present utility model achieves the sealing rubber strip in contact with the edge of the door frame, reduces the size of the door gap, thereby reducing the probability of dust entering the distribution box, realizes the high sealing, and prevents the operator from inhaling a lot of dust. In a dark environment, the operator does not need to hold a light, which reduces the operator's labor and facilitates the operation.
