Description
Technical field
The utility model relates to a kind of circuit breaker, especially relates to a kind of electrical wiring device of air circuit.
Background technology
Circuit breaker is the general designation of low pressure trippers such as automatic circuit breaker, isolating switch, electric wire connecting junction.Circuit breaker is mainly used in the concrete part of electrical system and being connected of load.Along with production application, the installation method of circuit breaker is more various, mainly contains: one, " fix " form of implementation, promptly the electric terminal of circuit breaker directly stably is connected on the conductor of distribution line, and this method is applicable to immutable situation; Two, " insertion " form of implementation uses specific interconnecting device to be connected with mechanical system with distribution board, and each circuit breaker mechanically is coupled to corresponding interconnecting device; Three, " can plug " form of implementation, this method is to increase subsidiary component on the basis of second method, and interconnecting device is plugged, and this method flexibility is big, installation or removal circuit breaker promptly, and do not influence other parts of electrical system.
Summary of the invention
The purpose of this utility model is to provide the electrical wiring device of the air circuit that a kind of contact is good, security reliability is high.
The utility model is provided with and receives chuck and insert terminal;
Described reception chuck is provided with left steel intermediate plate, right steel intermediate plate, left copper intermediate plate, right copper intermediate plate, adjustable shelf and clamping screw, described left steel intermediate plate and left copper intermediate plate, right steel intermediate plate and right copper intermediate plate are fixed on the adjustable shelf left and right sides by clamping screw respectively, described left steel intermediate plate is located at the left copper intermediate plate outside, right steel intermediate plate is located at the right copper intermediate plate outside, the end of described left steel intermediate plate, right steel intermediate plate, left copper intermediate plate, right copper intermediate plate all has the swallow-tail form projection, is receiving the slotting porch formation of chuck swallow-tail form; Described insertion terminal is a concave structure, the side flange that the contact portion that the insertion of inserting terminal receives chuck is provided with and the swallow-tail form projection of left copper intermediate plate and right copper intermediate plate cooperates, and the rear portion of insertion terminal is provided with the binding post step.
When described insertion end subdivision is inserted the reception chuck, insert the side flange and the interior side contacts that receives chuck of terminal, and cooperate with the swallow-tail form that receives chuck is protruding; The swallow-tail form that receives chuck contacts with the lateral surface that inserts terminal, and the insertion terminal is formed spacing, prevents to become flexible.Insert terminal like this and can cooperate conducting more stably more reliably with the reception chuck.
This shows that advantage of the present utility model is:, it is cooperated more reliably, conducting more stably by the structure of chuck and terminal is improved; To the side flange that inserted terminal design, side flange cooperates with the swallow-tail form projection better, and improvements are simple in structure.
