As preferably, the rearward end of described horizontal part is wider than the rearward end of horizontal part.
As preferably, the width of described vertical portion is less than the width of horizontal part rearward end, and the one side setting of horizontal part rearward end is departed from described vertical portion.Wherein, horizontal part rearward end one side setting is departed from vertical portion has increased coefficient of safety when safe distance improves use.
A kind of moulded case circuit breaker of the present utility model, comprise base, bat-handle switch, be buckled in the shell on base, moving contact on base, fixed contact and shunt release, the rear and front end of described base is respectively arranged with a pair of splicing ear, has at least a splicing ear to be connected with shunt release, described the first connecting hole is provided with binding post, the second connecting hole is connected with base by securing member, and described shunt release is connected with moving contact, and moving contact is connected with fixed contact.Wherein, use " L " type splicing ear with two holes instead, with binding post, directly be fixed on the first connecting hole, do not need to assemble the employee in addition to the adjustment of metallic sheath firmware, greatly facilitate employee's assembling, wiring, and can, because of assembling and use procedure, not cause outer connection loosening, prevent that metal part is directly outside exposed and the electric shock electric leakage accident that causes has strengthened use safety.The second connecting hole is connected with base by securing member, and splicing ear and shunt release adopt that metal electric is soldered to be connect, and make inner the connection more firmly be not easy to come off, and have extended useful life.When overcurrent or short circuit, shunt release is moved frame, and the frame tripping makes moving contact separate with fixed contact, makes circuit disconnect.
As preferably, described shell arranges the curved surface that bat-handle switch place outwardly convex forms certain radian.Wherein, the curved surface of certain radian, the sharp right angle that has reduced product to human body improper touching shine into injury, thereby strengthened the fail safe of this real novel plastic casing type circuit breaker.
As preferably, the rear and front end section of described shell forms respectively nearly fillet.Wherein, form sharp right angle that nearly fillet reduced product to human body improper touching shine into injury, thereby strengthened the fail safe of this real novel plastic casing type circuit breaker.
As preferably, described shunt release is the oil damping release.
Therefore, the utlity model has following beneficial effect: splicing ear is convenient for assembly, easy-to-connect is quick, avoided inner parts and terminals to expose simultaneously, useful life and the safety in utilization of circuit breaker have been improved, shell arrange rear and front end section that bat-handle switch place outwardly convex forms the curved surface of certain radian and shell form respectively sharp right angle that nearly fillet reduced product to human body improper touching shine into injury, thereby strengthened the fail safe of this real novel plastic casing type circuit breaker.
