Connection structure for front frame and panel of insertion box

The invention discloses a connection structure for a front frame and a panel of an insertion box. The connection structure comprises a panel part with a first convex member, a front frame portion and at least two connecting parts. An upper end face of the front frame portion has a first concave rabbet, the first convex member and the first concave rabbet are engaged with each other after the front frame portion is attached to the panel part, a lower end surface of the front frame portion has a second protruding member for the engagement with a second concave rabbet on the housing. The at least two connecting parts are clamped on a side wall of one side of the front frame portion and are used for connecting the panel part, and the panel part can rotate a certain angle with the connecting parts as rotating centers. The technical problems of poor electromagnetic shielding performance and complicated processing and assembly processes are overcome, the overall electromagnetic shielding performance of an insertion
