Abstract

The invention provides a junction box, which comprises a base, an upper cover matched with the base, a plurality of terminals and diodes electrically connected with the adjacent terminals, wherein the base is provided with an accommodating cavity, a bottom wall positioned below the accommodating cavity and a front wall positioned in front of the accommodating cavity, a ventilating device is protruded from the bottom wall toward the accommodating cavity, the ventilating device is provided with a ventilation hole, the ventilation hole is provided with a first opening positioned in the base and a second opening positioned in the outer side of the front wall, the first opening faces upward, the second opening faces forwards, and the first opening is covered by a breathable film. Thus, water vapor and dust are prevented from directly falling on the breathable film, and the blockage probability of the breathable film is effectively reduced.

Description

technical field [0001] The invention relates to a junction box, in particular to a solar junction box. Background technique [0002] A solar junction box generally includes a base, an upper cover matched with the base, a number of terminals and diodes accommodated in the base. Since the diode will generate a lot of heat during the working process, in order to ensure the balance of air pressure inside and outside the junction box, there are vent holes on the base, and a ventilating film is arranged in the vent holes, so that the junction box can be reduced under the premise of ensuring a good airtight performance. The purpose of the internal pressure of the junction box. In existing products, the ventilation holes are generally designed to be straight up and down, so that external water vapor and dust will directly fall on the ventilating membrane, which will cause the ventilating membrane to be blocked, and the ventilating function cannot be realized. [0003] Therefore, i...
