The invention discloses an electric junction box with the moisture removing function. The electric junction box comprises a fixed side plate, contact tapered heads, a dehumidifying and dustproof device, screws, an access line end box, a box body, a bonding board, and hinges. The two contact tapered heads are embedded into the fixed side plate vertically; and the dehumidifying and dustproof deviceis fixed connected to the inside of the box body by means of gluing. Compared with the prior art, the electric junction box disclosed by the invention has the following advantages: a fixed elastic force is applied to the box cover by using the traditional elastic force effect and the box cover is fixed by the external force; and the box cover can be opened automatically only by dismounting the twoscrews when needing to be replaced, so that the speed of replacing the wiring terminal is increased and the device replacement convenience is improved. Because of timing controlling of a micro braking device, a rotating mechanism and a sliding mechanism are driven and a transmission mechanism applies forces to a dehumidifying motor device to remove the moisture and dust inside the junction box, so that the service life of the box is prolonged and the connection effect of the wiring contact point is improved.
