The invention discloses a terminal box with the damp-proof function. The terminal box comprises a box body. A cabinet door is formed in the box body. An air inlet and an exhaust port are formed in the side wall of the box body. An air inflow fan is installed on the air inlet. An exhaust fan is installed on the exhaust port. An electric heater is further installed in the box body. According to the terminal box, the air inflow fan is installed on the air inlet, the exhaust fan is installed on the exhaust port, and the electric heater is installed in the box body, so that after moisture is heated by the electric heater, the temperature of the moisture in the terminal box is increased, the moisture becomes vapor, the vapor ascends after the temperature of the vapor is increased, the vapor is exhausted out of the terminal box under the effect of the exhaust fan located in the high position, cold air is input into the terminal box from outside through the air inlet located in the low position, the interior of the terminal box is in a dry environment with the proper temperature all the time, the oxidation rate of terminals is reduced, and the service life of the terminals can be prolonged.
Description
technical field [0001] The invention relates to a terminal box, in particular to a terminal box with a moisture-proof function. Background technique [0002] The terminal box is a kind of interface device that is used to switch construction lines, store branch lines, and provide convenience for wiring and checking lines. In some cases, in order to facilitate construction and debugging, some special and regularly installed products such as short-circuit isolators can be installed in the terminal box; terminal is an accessory product used to realize electrical connection , Industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. At present, in addition to PCB board terminals, there are...
