[0005] 2, the fixed screw on the panel adopts detachable screw, when operating the panel, because the fixed screw is small, it is easy to fall, if falling into other electrical equipment, it will cause equipment short circuit and other faults. INVENTION CONTENTS

[0006] The utility model aims at providing a power distribution unit for comprehensive distribution box.

[0007] In order to achieve the above object, the following technical scheme is adopted:

[0008] A power distribution unit for comprehensive distribution box, including frame weldment, panel assembly, guide rail, ground copper bar, zero line copper bar, the panel assembly is connected and fixed with the frame weldment through the screw that does not loosen, the guide rail, the ground copper bar, zero line copper bar are connected with the frame weldment through fixed screw, wherein, the guide rail, the ground copper bar, zero line copper bar are located in the frame weldment, the panel assembly includes panel and the sunken protection frame that sets up on the panel, the switch of miniature circuit breaker installed on the guide rail is located in the protection frame.

[0009] Further, the protection frame sinks towards the inside of the frame weldment.

[0010] Further, the both sides of the frame weldment are provided with mounting ears through fixed screws.

[0011] Further, the frame weldment is installed in the comprehensive distribution box through the mounting ear.

[0012] With the above scheme, the utility model has the beneficial effects that:

[0013] The panel assembly adopts a sunken structure, which solves the problem that the toggle switch of the miniature circuit breaker is easily touched and causes misoperation and safety accidents during use after the miniature circuit breaker (air switch) is installed on the guide rail.

[0014] Through the loose screw, the screw will not fall off during the operation of the panel, and the safety of other equipment inside the power distribution unit is protected. BRIEF DESCRIPTION OF DRAWINGS
