Junction box assembly

A junction box assembly, comprising:

• a main body on which an electric circuit is disposed, and having at least one socket electrically connected to the electric circuit;
• a first cover covering one surface of the main body on which the electric circuit is disposed;
• a second cover covering another surface of the main body opposite to said one surface, and having a connector corresponding to the at least one socket;
• and
• a coupling unit fastening the main body and the second cover together by a sliding motion thereof such that the socket and the connector are coupled to each other, wherein the coupling unit comprises:
• at least one guide projection disposed on the second cover;
• a slider slidably disposed on the main body corresponding to the guide projection;
• a projection sliding portion disposed on the slider correspondingly to the guide projection, and having a slot inclined at a predetermined angle such that the guide projection perpendicularly moves with respect to a direction of movement of the slider according to movement of the slider;
• and
• a pressing portion for moving the slider, said pressing portion comprising:
• a linking bar having an end pivotally coupled to an end of the slider by a dynamic axle;
• and
• an indirect pressing lever fixed to another end of the linking bar with a predetermined angle therebetween, wherein a fixed portion is pivotally coupled to the main body by a stationary axle, such that, when the indirect pressing lever is pressed, the linking bar rotates with respect to the stationary axle and accordingly moves the dynamic axle and the slider.
