Fig. 1 is for illustrating the structural representation with a kind of exemplary embodiment of security component of the switch of fuse.As shown in Figure 1, with the security component of the switch of fuse, comprise a casing 10, side cover 20, protecgulum 30, driving shaft 40 and a locking piece 50.
Wherein, casing 10 is for the internal mechanism of the switch of packaging belt fuse.Casing 10 has one end face 12 is installed.In the embodiment shown in fig. 1, this installation end face is positioned at the upper surface of casing 10.
Side cover 20 can be connected in installation end face.Protecgulum 30 can be connected in side cover 20.Side cover 20, protecgulum 30 and installation end face 12 can enclose one for encapsulating the space of the fuse of switch.Protecgulum 30 can rotate with respect to side cover 20, thereby makes fuse exposed.Protecgulum 30 has a sticking department 32.As shown in Figure 1, in a kind of exemplary embodiment of security component of the switch with fuse, protecgulum 30 is provided with a leading section 34 and a side end 36.One end of leading section 34 is connected in side cover 20 rotationally.One end that leading section 34 is not connected with side cover is connected in side end 36.At side end 36, away from one end of leading section 34, be provided with sticking department 32.
Driving shaft 40 arranges in casing 10, and driving shaft 40 can be driven driven rotary by operating grip or drive motors, thus being electrically connected between switching activity contact and fixed contact.Driving shaft 40, in the process of rotation, is provided with an open position and a make position.When driving shaft 40 is during in open position, be arranged between armature contact in casing 10 and fixed contact separated; When driving shaft 40 is in the close position, the armature contact being arranged in casing 10 contacts with fixed contact.On driving shaft 40, be provided with one first drive division 42, this first drive division protrudes from the periphery of driving shaft 40.In a kind of exemplary embodiment of security component of the switch with fuse, driving shaft 10 also has second drive division 44 that protrudes from its periphery.The first drive division 42 and the second drive division 44 can be the lug bosses radially extending along driving shaft 40.In addition, in other exemplary embodiment of the security component of the switch with fuse, security component comprises a driving-disc that is socketed on driving shaft, and the first drive division and the second drive division are arranged on driving-disc or with described driving-disc and are integrally formed.
Locking piece 50 has a keyed end 52, connecting portion 54 and a drive end 56.Connecting portion 54 is between keyed end 52 and drive end 56.Connecting portion 54 is connected in casing 10 rotationally, thereby locking piece 50 can be rotated with respect to casing 10.In a kind of exemplary embodiment of security component of the switch with fuse, casing 10 is provided with a connection bump 18.Connecting portion 54 is provided with a connecting hole 542.Connecting portion 54 is socketed on connection bump 18 by connecting hole 542, thereby realize locking piece 50, with respect to casing 10, rotates.
Sticking department 32 is provided with the snap fit towards keyed end 52 bendings.Keyed end 52 is provided with the snap fit towards sticking department 32 bendings.The snap fit of keyed end 52 can be connected in the snap fit of sticking department 32, and protecgulum 30 cannot be rotated with respect to side cover 20.The first drive division 42 of driving shaft 40 can contact with drive end 56 respectively with the second drive division 44, thereby drives locking piece 50 to rotate with respect to casing 10.
Fig. 2 to Fig. 4 is for illustrating the motion process with the security component of the switch of fuse.In order to clearly illustrate locking piece and protecgulum, in figure with dotted lines side cover.As shown in Figure 2, now driving shaft 40 in open position.The second drive division 44 contacts with drive end 56, and due to leverage, keyed end 52 is pressed from sticking department 32.Protecgulum 30 can overturn with respect to side cover 20, thereby makes fuse exposed.Now, the armature contact of switch is separated with fixed contact, changes the danger that fuse does not exist electric shock.
As shown in Figure 3, when driving shaft 40 starts to be rotated to make position by open position, the second drive division 44 disengagings contact with drive end 56, and the first drive division 42 does not also contact with drive end 56.Keyed end 52 is away from sticking department 32.
Driving shaft 40 continues to be rotated to make position by open position.As shown in Figure 4, when driving shaft 40 turns to moment of make position, the first drive division 42 contacts with drive end 56 and promotes drive end 56, and locking piece 50 is rotated counterclockwise.The rotation of locking piece 50 make keyed end 52 towards sticking department 32 rotate and interlocking in sticking department 32.Due to keyed end 52 and the mutual interlocking of sticking department 32, protecgulum 30 cannot rotate with respect to side cover 20.
When driving shaft is rotated to open position by make position, contrary with the described process of Fig. 2 to Fig. 4 with the motion process of the security component of the switch of fuse, do not repeat them here.
With the security component of the switch of fuse, when driving shaft is in the close position, because keyed end and sticking department are mutually locked, can avoid protecgulum to rotate with respect to side cover, thereby avoid fuse exposed.In the process of drive shaft turns, only have when drive shaft turns is during to make position, the first drive division just drives locking piece to rotate, make keyed end rotationally interlocking in sticking department.In whole process, between keyed end and sticking department, do not exist with respect to friction, and do not have gap between keyed end and sticking department.When driving shaft is in the close position, can there is not relative motion in protecgulum and side cover, can avoid thus sticking department and/or locking piece stress deformation and disengaging mutually.
In addition, by leading section and side end are set, can be so that the close end face of installing of the active position of keyed end and sticking department.Can shorten the size of keyed end thus, reduce keyed end stress deformation.
Fig. 5 has shown the structural representation with the another kind of exemplary embodiment of security component of the switch of fuse.As shown in Figure 5, casing 10 is provided with a mounting blocks 14.Security component with the switch of fuse comprises a spring 51.One end of spring 51 is resisted against mounting blocks 14, and the other end of spring 51 is resisted against drive end 56.When driving shaft 40 is rotated to open position by make position, the first drive division 42 departs from drive end 56, and the elastic force that spring 51 produces promotes locking piece 50 and clockwise rotates, thereby makes keyed end 52 release lock bonding parts 32.
Fig. 6 has shown the structural representation with the another kind of exemplary embodiment of security component of the switch of fuse.As shown in Figure 6, casing 10 is provided with a mounting blocks 14.Security component with the switch of fuse comprises a leaf spring 53.One end of leaf spring 53 is resisted against mounting blocks 14, and the other end of leaf spring 53 is resisted against drive end 56.When driving shaft 40 is rotated to open position by make position, the first drive division 42 departs from drive end 56, and the elastic force that leaf spring 53 produces promotes locking piece 50 and clockwise rotates, thereby makes keyed end 52 release lock bonding parts 32.
Fig. 7 has shown the structural representation with another exemplary embodiment of security component of the switch of fuse.As shown in Figure 7, casing 10 is provided with a mounting blocks 14.Security component with the switch of fuse comprises a torsion spring 55.Torsion spring 55 is socketed on connection bump 18.One end of torsion spring 55 is resisted against mounting blocks 14, and the other end of torsion spring 55 is resisted against drive end 56.When driving shaft 40 is rotated to open position by make position, the first drive division 42 departs from drive end 56, and the elastic force that torsion spring 55 produces promotes locking piece 50 and clockwise rotates, thereby makes keyed end 52 release lock bonding parts 32.
