Embodiment
Fig. 1 and Fig. 2 are asked for an interview in
, and the circuit breaker that provides comprises auxiliary switch 1, circuit breaker action component 2.2 pairs of auxiliary switches of circuit breaker action component 1 transmit the circuit breaker actuating signal.Circuit breaker action component 2 comprises connecting rod 21 and single-pole switch body 22, and connecting rod 21 connects auxiliary switch 1 and single-pole switch body 22.Give auxiliary switch 1 by connecting rod 21 with the operating mechanism disconnection or the closed action transmission (conduction) of single-pole switch body 22, and export the signal of the on-off of single-pole switch body 22 through auxiliary switch 1.If described circuit breaker action component 2 adopts other common forms,, promptly belong to the scope of lid that contains of circuit breaker action component 2 in the utility model as long as can promote auxiliary switch 1 action.
Fig. 3 to Fig. 8 is asked for an interview in
; Auxiliary switch 1 comprises shell 11, sensitive switch 12, rotating shaft 13 and rotating shaft back-moving spring 14; Sensitive switch 12 is fixed on a pair of parallel sensitive switch fixed axis 121 through a pair of fixed shaft hole 123 on it; Be that a pair of sensitive switch fixed axis 121 is placed through on the sensitive switch 12, the two ends of sensitive switch fixed axis 121 are fixed on shell 11.According to known general knowledge, sensitive switch 12 has a button 122.The split type structure of shell 11 preferred employings; So-called split type structure is meant: shell 11 is made up of upper and lower case 111,112 jointly; And, on upper encloser 111, constitute upper encloser fixture 1111, and on lower encioser 112, constitute lower encioser fixture 1121 by shown in Figure 7; Because upper and lower case fixture 1111,1121 is inserted scarf each other and is closed, and installs very convenient thus.The position of upper and lower case fixture 1111,1121 can be exchanged, as long as ensureing that both correspond to each other and are able to cooperates, specifically by shown in Figure 8.Rotating shaft 13 is arranged on the shell 11 rotationally; More properly say and be arranged on the lower encioser 112; In this rotating shaft 13, constitute the strike portion 131 (also can claim to hit the finger-type plate) of the button 122 that is used to hit aforesaid sensitive switch 12; And constitute the forced section 132 of the effect that is used to accept aforesaid circuit breaker action component 2, will be the driving of accepting connecting rod 21 more specifically.Rotating shaft back-moving spring 14 is arranged in the rotating shaft 13, and an end of this rotating shaft back-moving spring 14 an i.e. spring pin is bearing on the forced section 132, and the other end to be another spring pin be bearing on the shell 11.
are as the technical essential of the utility model: make the quantity of aforesaid sensitive switch 12 increase to two or three by unique one (to an auxiliary switch 1) in the prior art; Correspondingly the quantity of the aforesaid strike portion 131 in the rotating shaft 13 also increases to two or three; Each strike portion 131 is corresponding one by one with the button 122 of sensitive switch 12; Act on forced section 132 with convenient connecting rod 21; And rotating shaft 13 is rotated towards the direction of button 122; Thereby the button 122 by each (three) strike portion 131 hits each (three) sensitive switch 12 simultaneously moves and exports synchronously the make-and-break signal that auxiliary circuit changes with in realizing at one time.Preferred scheme because the quantity of sensitive switch 12 is three (having illustrated two among Fig. 6), therefore adopts the dividing plate of being filled the post of by insulating material 3 to separate, so that improve insulation property between the adjacent sensitive switch 12.
emphasis is seen Fig. 4 and Fig. 5; The concrete scheme that rotating shaft 13 is arranged on the shell 11 rotationally has two: the one, in rotating shaft 13, offer fixed shaft hole; Insert fixed axis 133 in the hole; With being supported at both ends on the shell 11 of fixed axis 133, rotating shaft 13 then can be rotated on fixed axis 133 freely.The 2nd, respectively be extended with a hub setting spindle nose (not going out) at the two ends of the length direction of rotating shaft 13 by illustrated, a pair of hub setting spindle nose is arranged on the shell 11 rotationally.Again, two kinds of schemes are also arranged for rotating shaft back-moving spring 14: the one, adopt a rotating shaft back-moving spring 14, it is nested with appointing in a pair of spindle nose of fixed axis 133 selects on the spindle nose, perhaps be nested with on any hub setting spindle nose in a pair of hub setting spindle nose.The 3rd, adopt a countershaft back-moving spring 14, on a pair of spindle nose of fixed axis 133 each sheathed one, perhaps on a pair of hub setting spindle nose each sheathed one.And, also can in rotating shaft 13 and at position, form spring container cavity 134, so that supply rotating shaft back-moving spring 14 to hold corresponding to rotating shaft back-moving spring 14.
can be known by above-mentioned explanation, and the quantity of sensitive switch 12 is (to comprise two) more than two, and plural sensitive switch 12 is controlled by same rotating shaft 13, thereby can realize the many groups of output circuit breaker make-and-break signals synchronously preferably.Solve the existing shortcoming of prior art, reached the innovation and creation purpose
