Abstract
The utility model relates to an electronic type overload relay convenient for fixing a current transformer. The overload relay is characterized by comprising an electronic type overload relay substrate, a rear cover and the current transformer, wherein a connecting lead of the current transformer, connected with a contactor, is provided with an extruded flat groove fin; and the flat groove fin is inside an connecting lead outlet formed after the current transformer is well assembled in the substrate and then the connecting lead is assembled with the substrate and the rear cover. Due to the adoption of the extruded flat groove fin on the connecting lead of the current transformer connected with the contactor, the overload relay causes the connecting lead of the current transformer to be clamped at the lead outlet synthesized by the base of the electronic overload relay and the rear cover through the flat groove fin, thus realizing the effect of fixing and reducing the movement amount of the current transformer inside a shell, ensuring the reliable connection between the overload relay and the contactor, and simultaneously solving the problem of poor contact at a lower-mouth connecting end.
Description
Technical field
The utility model belongs to a kind of electric switch, particularly relates to a kind of electronic overload relay of being convenient to the fixed current instrument transformer.
Background technology
Present known rated current grade is fixing not firm at the current transformer of the electronic overload relay inside of 20-40A and 32-63A, current transformer is bigger at the enclosure interior amount of movement, cause the overhang of major loop terminals of overload relay different in size, influence overload relay and install with the grafting of corresponding contactor.Simultaneously the end opening binding post also can the indentation housing in, cause the terminals loose contact of end opening, the usability and the fail safe of overload relay caused harmful effect.
Summary of the invention
The utility model provides a kind of electronic overload relay of being convenient to the fixed current instrument transformer that can be more firm for solving the technical problem that exists in the known technology.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: it includes electronic overload relay pedestal, bonnet summation current transformer, in being connected of being connected with contactor of its of described current transformer flat groove wing that squeezes out is arranged on the lead; The position of described flat groove wing be, its described connection lead and described pedestal and bonnet assembling back constitutes the described inboard that is connected the line outlet of lead after current transformer assembles in described pedestal.
The advantage that the utlity model has with good effect is: since adopted current transformer be connected with contactor be connected the flat groove wing that squeezes out on the lead, the connection lead that makes current transformer is with pedestal and the bonnet synthetic lead line outlet place of flat groove wing fixing at electronic overload relay, thereby obtained fixing, reduced current transformer at the enclosure interior amount of movement.Guarantee reliable connection the between overload relay and the contactor, solved the loose contact problem of end opening terminals simultaneously.
