When the correct plug-in mounting of fuse unit advances in the housing, that is when not installing on the predetermined terminal position between two contacts of switch case, locking device promptly stops shift bar to be changed over to make position.Like this, the user can discover wrong at once, thus the position that can correct fuse unit.
Therefore, switch only at fuse unit by correct plug-in mounting, and make its with switch case on when electric contact correctly is bonded together accordingly, could connect.Because when fuse unit during at errors present, switch can form the arc gap between the corresponding electric contact on the electric contact of fuse unit and the housing, so that in the time will closing, will produce electric arc, by with upper type, this switch then can stop the generation of this situation reliably.In addition, guarantee that also fuse unit is in the tram when switch connection, and during corresponding electric equipment operation, owing to electric contact is reduced to the current interruptions that trouble unit causes and can not produced.
Locking device is made of a protuberance that is positioned on the shift bar, and when fuse unit was in tram and shift bar and turns to make position, this protuberance promptly entered in the recess that the bearing upper end of fuse unit is provided with for this purpose.When if fuse unit is plugged in errors present, this protuberance promptly abuts against on the bearing, stops shift bar to be rotated further.
Fuse unit fastening in switch case realizes with a spring that mainly this spring makes the contact that is keeping movably in the switch case, compresses in advance facing to the electrode of plug-in fuse, thereby required contact force also is provided.Be the set recess of shift bar protuberance, mainly be positioned at the upper end of fuse unit, i.e. the relative end of an end that with the spring roof pressure can make fuse unit unlikely departing from and being back on the errors present again when switch connection like this.But also can arrange like this,, make fuse unit move to the tram promptly by the protuberance of shift bar.
Brief description of drawings
Below in conjunction with embodiment of accompanying drawing specific explanations, wherein,
Fig. 1 is that switch sections is cut open, and housing is opened, the correct Status view of pegging graft of fuse unit.
Fig. 2 is that the switch by Fig. 1 is in the view under the on-state.
Fig. 3 is the switch by Fig. 1, the view when fuse unit is pegged graft mistake.
Embodiment
This switch has a housing 10 of being made by the resin of electric insulation, the mode that this housing is known with everybody constitutes the housing of rail-clamp, shown in bottom among the figure, has a notch locking mechanism 12, to be used for being locked in fuse block shown in the figure and distribution box or similar thing.Binding post 14,16 in housing 10 relative both sides is used as the terminal of fixedlying connected with not shown outer cable, is electrically connected by foundation of switch between or interruption.
Joining with another binding post 16 is a connecting plate 38 in addition, and it and middle connecting plate 32 constitute the terminal block of fuse unit 40 together.Fuse unit 40 has a bearing 42 that in fact forms U-shaped, and the cannula type fuse can be put into bearing 42, and the electrode 46 and 48 of the opposite end of cannula type fuse is used easily.
Middle connecting plate 32 is that bearing 42 constitutes a bracket, is that the electrode 46 of cannula type fuse 40 constitutes a corresponding tie point simultaneously.The far-end of middle connecting plate 32 is supported on the housing 10 by a compression spring 50, makes middle connecting plate face toward electrode 46 and compresses, and then the electrode 48 of the other end that is positioned at cannula type fuse 44 is pressed on the connecting plate 38.Bearing 42 inserts in the housing 10 in the mode that tilts, and there is a detent bumps end 52 on 48 next doors in the contact, and detent bumps end 52 is stuck in the rib 54 of housing, and bearing 42 is fixed on the position in its housing.The upper end of bearing 42 is that the free end of shift bar 18 constitutes a supporting 56.
On shift bar 18 rigidly connected cams 22, be provided with protuberance 58 towards fuse unit 40 sides.Corresponding recess 60 coordinations on the outer wall of this protuberance 58 and bearing 42.
Switch cam 22 and the fixed center of compressing spring 36 formation shift bars 18.Under state shown in Figure 1, handle 18 produces LAP to the right towards its make position makes switching cam surpass the dead point, and by connecting together linkage element 24 towards the further deflection of closing direction with compression spring 36.
Fig. 2 shows shift bar 18 and all changes make position over to, and is seated in the state in the supporting 56.Under this state, cross structure 26 keeps closely contacting with 40 with tie point 30 by compression spring 36, thus pass through connecting plate 28,32 and 38 and cannula type fuse 44 make cable connection post 14 and 16 finish electric connection each other.In addition, can find out that in Fig. 2 the protuberance 58 that links with shift bar 18 rigidity accepted by the recess 60 on the bearing 42 of fuse unit.
