Abstract

The invention discloses a moisture-proof junction box. The moisture-proof junction box comprises a junction box body, a connecting conductor and a heating part, wherein the connecting conductor and the heating part are located in the junction box body, the two ends of the connecting conductor are used for being connected with an incoming cable and an outgoing cable respectively, and the heating part is matched with the connecting conductor to generate an eddy current effect so as to generate heat. According to a scheme in the invention, the heating part in the junction box body is matched withthe connecting conductor, the eddy current effect is used for heating, and the generated heat can prevent condensation in the junction box, so water vapor is effectively discharged, and a moisture-proof purpose is achieved. The scheme can realize heating of the heating part without an additional power supply, and the junction box is simple in structure, safe and reliable to operate, low in cost and easy to use.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a moisture-proof junction box. Background technique [0002] In the installation process of mechanical and electrical equipment in tunnel engineering, pipe gallery engineering and underground space, a large number of junction boxes are required for wiring cables and wires. Due to the humid underground environment, ordinary junction boxes are prone to condensation, which will cause the wires in the junction box to corrode and fall off or cause leakage and short circuit, which will affect the normal operation of the equipment and bring great safety hazards. [0003] In the prior art, the construction unit usually adopts measures such as installing a sealing strip at the interface of the junction box to strengthen the seal to prevent the intrusion of water droplets. However, in practice, it has been found that due to the aging of the sealing strip or the looseness of the wir...
