In Fig. 1, illustrated of the present invention can the more breaker body 2 of changer controller and the contour structures of controller 1 of fast insert-pull, the internal structure of face shield 3 and the lock slots 31 of the portion that sets within it have been shown in Fig. 2, shape and structure, obform guide rail pair 5 that support 4 has been shown in Fig. 3 are arranged on the compound chute 541 on support 4, and the installation site of socket 210, in Fig. 4, illustrate that the structure of elastic locking mechanism 6 and obform guide rail pair 5 are arranged on the compound slide block 511 on controller 1.Referring to the execution mode of Fig. 1 to Fig. 4, annexation between controller 1 and breaker body 2, face shield 3 is, by the support 4 being fixed on breaker body 2, controller 1 is positioned, again by controller 1 elastic locking on face shield 3, support 4 is by known connected mode, as the connecting hole 41 by support 4 and screw (figure China and foreign countries illustrate) are fixed on breaker body 2.Obform guide rail pair 5 refers to the rail plate pair being made up of a pair of chute, slide block, and obform guide rail pair 5 is for installing location by controller 1 and support 4, and the plug operation that it is controller provides the necessary guiding accuracy that comprises positional precision and directional precision.The existing guiding mechanism being made up of four leads and four pilot holes comprises four column type guideways, and each guideway can only limit four degrees of freedom, be equivalent to 4 degrees of freedom that directions X in the rectangular coordinate system shown in Fig. 4 moves, Y-direction moves, rotate and rotate around Y-axis around X-axis, therefore it at least needs two column type guideways could meet operation principle requirement.But, the present invention only adopts 1 obform guide rail secondary 5 just can meet same requirement completely, be understood that in conjunction with Fig. 1 to 4, controller 1 is realized by obform guide rail secondary 5 with respect to the location of breaker body 2, specifically, it has by a guideway just can limit 5 degrees of freedom feature of (referring to 5 degrees of freedom that directions X in the rectangular coordinate system shown in Fig. 4 moves, Y-direction moves, rotate, rotate and rotate around Z axis around Y-axis around X-axis), and guiding accuracy and location (directions X, Y-direction) precision is high, simple in structure, be easy to manufacture.
The concrete structure of obform guide rail pair 5 of the present invention can have multiple, preferably following three kinds.One is as shown in Fig. 1,3,4,7, described obform guide rail secondary 5 is compound rail plate, comprise the compound slide block 511 being arranged on controller 1 and be arranged on the compound chute 541 on support 4, that is: comprising at same compound chute 541 inner plane a, side plane b, outerplanar c and the tapered plane d that a pair of symmetrically arranged and compound slide block 511 is slidably matched.Visible, the present invention utilizes the compound slide block 511 on controller 1 to aim at insertion with the compound chute 541 being contained on breaker body 2 in the time that controller 1 is installed, can realize controller 1 required electric loop of normal work in circuit breaker by slide block and the cooperation of corresponding chute connects, realize the plug 110(Fig. 4 on controller 1) and breaker body 2 on socket 210(Fig. 3 of circuit board electrical connection) between automatic precise positioning, then utilize locking piece 61 to rotate and get final product lockout controller 1 or utilize locking piece 61 to rotate and can take out controller 1(referring to Fig. 5, 6).The concrete structure of the second obform guide rail pair 5 as shown in Figure 8, described obform guide rail secondary 5 is square type rail plate, comprise the square type slide block 512 being arranged on controller 1 and be arranged on the square type chute 542 on support 4, that is: comprising a pair of symmetrically arranged inner plane a, side plane b and the outerplanar c being slidably matched with square type slide block 512 at same square type chute 542.The third is obform guide rail pair 5 as shown in Figure 9, for dove-tail form rail plate, comprise the dove-tail form slide block 513 being arranged on controller 1 and be arranged on the dove-tail form chute 543 on support 4, that is: comprising a pair of symmetrically arranged inner plane a and the tapered plane d being slidably matched with dove-tail form slide block 513 at same dove-tail form chute 543.Above-mentioned three kinds of obform guide rail pairs 5 all can realize two functions of guiding and location simultaneously, and these two functions are automatically to complete in the operating process of inserting controller 1.Certainly, do not get rid of the situation that simultaneously adopts more than two obform guide rail pair 5, as stressed for improving, can be according to the quantity of the number configuration obform guide rail pair 5 of locking mechanism 6.Under normal circumstances, easy to operate for not affecting, the quantity of obform guide rail pair 5 is no more than two.
In fact, the location of controller 1 in direction of insertion (the Z direction in the rectangular coordinate system shown in Fig. 4) can be selected scheme according to actual needs, as shown in Figs. 3-4, utilize the slide block end face 510 of obform guide rail pair 5 to coordinate the location of realizing direction of insertion with contacting of chute end face 540.Certainly, can also adopt other schemes, as the cooperation that contacts of the outer face (not shown) of the outer face (not shown) of socket 210 and plug 110, and for example the edge (not shown) of the outer flange (not shown) on controller 1 and the window 30 on face shield 3 contact cooperation, but no matter which kind of scheme, all in the operating process of inserting controller 1, automatically to complete location, make like this controller 1 and just can enter its normal operating conditions as long as insert to put in place, in other words, the lock operation process of follow-up locking mechanism 6 is after controller 1 enters normal operating state, and the unlocking operation process of locking mechanism 6 also can not affect the normal location of controller 1.As can be seen here, and adopt as screw between the controller in many existing circuit breakers and pedestal, clamping, being fixedly connected with of separate connection part such as knob are compared, because the dismounting of multiple separate connection parts must comprise plug and rotating operation, no matter be plug or rotation, all need the longer time of cost just can complete, and releasing is fixedly connected with also pretty troublesome with recovery, and the present invention is owing to having adopted the scheme of obform guide rail secondary 5 and locking mechanism 6, controller 1 is first located with rear locking and become non-interfering two processes, thereby make the time shorten of the normal work that affects controller 1 shared in the process of changer controller 1 more to just extracting the time required with inserting controller 1, really realize replacing operation extremely fast.
Fig. 5, in 6, further show the structure of elastic locking mechanism 6 and locking piece 61 thereof, as shown in the figure, controller 1 is provided with installing hole 11 and mounting groove 12, locking mechanism 6 comprises locking piece 61 and locking spring 62, locking piece 61 comprises cylindrical termination 611, cylindrical end tail 612 and the locking horizontal protruding 613 being arranged on cylindrical end tail 612, wherein, cylindrical termination 611 and cylindrical end tail 612 are pivotally mounted on respectively in installing hole 11 and mounting groove 12, be that cylindrical termination 611 is pivotally mounted in installing hole 11, cylindrical end tail 612 is pivotally mounted in mounting groove 12, by such installation, make the locking piece 61 can not only be around the center rotating of the installing hole of controller 1 11, and can also move along the axis direction of installing hole 11.The two ends of locking spring 62 are connected with controller 1 and locking piece 61 respectively, and in embodiment as shown in Figure 5, one end of locking spring 62 is connected with the shaft shoulder end face 614 on locking piece 61; The other end of locking spring 62 is connected with the end face 14 of the mounting groove 12 on controller 1.Locking spring 62 be stage clip, and it is sleeved on cylindrical end tail 612, locks spring 62 and acts on elastic force on locking piece 61 direction of extracting towards controller 1.Lock slots 31(Fig. 2 that locking horizontal protruding 613 and the face shield 3 of locking piece 61 is provided with) lock fit, that is: under locking mechanism 6 operating states (being under lock-out state), locking horizontal protruding 613 is rotated in lock slots 31, the elastic force of locking spring 62 makes locking horizontal protruding 613 lock with lock slots 31, and locking horizontal protruding 613 can not freely be deviate from lock slots 31, thereby controller 1 is locked on face shield 3; Deviate under the state of lock slots 31 in locking horizontal protruding 613, the locking between locking horizontal protruding 613 and lock slots 31 is disengaged, thereby controller 1 can be extracted and can depart from face shield 3.In order conveniently to extract operation, a kind of available scheme is, is provided with the nose bar 10 of extracting operation use on described controller 1, applies outside pulling force, so that controller 1 is easily extracted by nose bar 10 to controller 1.For attractive in appearance, can make the cylindricality termination 611 of locking piece 61 not reach outside the guidance panel of controller 1, or make not establish on locking piece 61 protruding knob, a preferred scheme is, when the end face of the cylindrical termination 611 of the locking piece 61 of described elastic locking mechanism 6 is provided with changer controller 1 more for the driver slot 6110 of conventional electrician's instrument (as screwdriver) update, to facilitate twist-lock part 61.In order to make elastic locking mechanism 6 can indicate locking or released state, a kind of preferred and simple scheme is, the cross sectional shape of described driver slot 6110 comprises the arrow 611a or the tip that are used to indicate lock-out state, certainly, the mark that represents locking or release is set on the relevant position of the panel of controller 1, more can realizes clear instruction at a glance.
For under released state, i.e. locking horizontal protruding 613 deviates under the state of lock slots 31, to obtain the stable plug state for the treatment of (state as shown in Figure 4 and Figure 5--locking piece 61 is under the elastic force of locking spring 62, its cylindricality termination 611 and cylindrical end tail 612 still can stablize remain in installing hole 11 and mounting groove 12), can or can stop that the position that cylindricality termination 611 or cylindrical end tail 612 move up arranges an anticreep end face 13 on controller 1, be used for stopping that locking horizontal protruding 613 moves up, thereby can prevent that cylindricality termination 611 and cylindrical end tail 612 from deviating from installing hole 11 and mounting groove 12, make controller 1 can carry locking piece 61 and locking spring 62 simultaneously.Certainly, the setting of anticreep end face 13 does not only make locking piece 61 depart from controller 1 under disarm state, therefore, without anticreep end face 13 in the situation that, does not affect normal work and the locking effect of elastic locking mechanism 6.
Referring to Fig. 3 and 4, can there be various ways the installation position of the socket 210 on breaker body 2, as be directly installed on breaker body 2, but in order to make plug 110 and socket 210 can obtain better plug quality of fit in plug process, a kind of preferred scheme is, described socket 210 is fixedly mounted on support 4, and fixed form can adopt known being fixedly connected with, and screw 42 is as shown in Figure 3 connected with screw (not shown).Obviously; compared with on being directly installed on breaker body 2; because obform guide rail pair 5 is to be separately positioned on controller 1 and support 4; therefore; socket 210 is fixedly mounted on the mode on support 4, can be easy to obtain positional precision, thereby can not only obtain higher plug quality of fit; can also be convenient to the assembly line Task of Debugging of large-scale production, can enhance productivity simultaneously.
Diverter switch 100 can be arranged on breaker body 2, also can be arranged on controller 1, and this diverter switch 100 can the power supply circuits of cutting-off controlling device or the power supply circuits of tripping coil.From being convenient for changing controller 1, preferred scheme as shown in Figure 1, is fixedly mounted on diverter switch 100 on controller 1.Face shield 3 is by known methods (as screw connects, clamping) be fixedly connected with breaker body 2, and for without dismounting, this is fixedly connected with when the changer controller 1 more, on face shield 3, have and hold window 30(Fig. 2 that controller 1 passes), the shape and size of window 30 are designed to not hinder controller 1 from outer insertion and the operation requirements extracted from outward.
Below taking two kinds of different replacing operating procedures as example, illustrate of the present invention can the more replacing operation of the circuit breaker of changer controller of fast insert-pull.The first is changed operating procedure and is comprised:
(1) electrician's instrument (screwdriver) is inserted to the driver slot 6110 of old controller 1, press screwdriver and drive locking piece 61 to rotate an angle with hand, make arrow 611a forward " release " position (now locking horizontal protruding 613 has automatically been deviate from from lock slots 31) to from " locking " position, loose one's grip again (now locking horizontal protruding 613 contacts with anticreep end face 13 automatically, and elastic locking mechanism 6 is in the plug state for the treatment of shown in Fig. 4 and Fig. 5);
(2) pull diverter switch 100 to " OF " position, the power supply of cutting-off controlling device 1;
(3) by drawing nose bar 10, old controller 1 is easily extracted, and old controller 1 is unloaded from breaker body 2 and face shield 3;
(4) slide block 511 of the obform guide rail pair 5 on new controller 1 is inserted to the chute 541 on support 4, then press new controller 1, new controller 1 is inserted and put in place;
(5) pull diverter switch 100 to " ON " position, connect the power supply of controller;
(6) electrician's instrument (screwdriver) is inserted to the driver slot 6110 of new controller 1, press screwdriver and drive locking piece 61 toward angle of back rotation with hand, make arrow 611a get back to " locking " position (now locking horizontal protruding 613 auto-alignment lock slots 31 goes out) from " release " position, then loose one's grip (now locking horizontal protruding 613 enters in lock slots 31 automatically) complete locking.
In order further to improve the fail safe of changing operation, can adopt following the second to change operating procedure:
(1) pull diverter switch 100 to " OF " position, the power supply of cutting-off controlling device;
(2) electrician's instrument (screwdriver) is inserted to the driver slot 6110 of old controller 1, press screwdriver and drive locking piece 61 to rotate an angle with hand, make arrow 611a forward " release " position (now locking horizontal protruding 613 has automatically been deviate from from lock slots 31) to from " locking " position, loose one's grip again (now locking horizontal protruding 613 contacts with anticreep end face 13 automatically, and elastic locking mechanism 6 is in the plug state for the treatment of shown in Fig. 4 and Fig. 5);
(3) by drawing nose bar 10, old controller 1 is easily extracted, and old controller 1 is unloaded from breaker body 2 and face shield 3;
(4) slide block 511 of the obform guide rail pair 5 on new controller 1 is inserted to the chute 541 on support 4, then press new controller 1, new controller 1 is inserted and put in place;
