Description
Technical field
The utility model relates to field of circuit breakers, more specifically, it relates to a kind of self-locking device of plug in circuit breaker.
Background technique
Existing miniature circuit breaker is all made of monolithic construction, using a complete shell by all kinds of groups of miniature circuit breaker
Part is assembled in shell, is also placed in together in this complete shell into and out of line end.It is installed in the bottom of miniature circuit breaker
Snap-gauge and miniature circuit breaker is mounted on standard rail by the standard rail by being mounted in ammeter box or distribution box.Into and out of
Line end connect with outer lead respectively and uses the screw in compression on miniature circuit breaker terminals, realizes to source side, load-side
It connects and realizes power supply and power-off with breaking operation, and thereby protect the safety of people, animal and property, equipment.
Existing miniature circuit breaker product needs to remove or need replacing other identical or not same size breaking down
When miniature circuit breaker, it is necessary to then need to remove external connecting leads from the terminals of miniature circuit breaker by breaker overall pulling down
And miniature circuit breaker is removed from the standard rail of installation again from being pulled out in the wiring hole of miniature circuit breaker.It is naked to be exposed on the external
Connecting wire constitutes security risk.If constraint of the miniature circuit breaker being mounted in ammeter box or distribution box by power supply department
When, user is then unable to self-changeable miniature circuit breaker.Do not allowing the place such as hospital, square, the communication that occur having a power failure for a long time
It will cause adverse effects for maincenter, data center, safety monitoring center.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of the self-locking of plug in circuit breaker
Device, so that breaker body and circuit breaker base cooperation are more reliable and more stable.
To achieve the above object, the utility model provides following technical solution:
A kind of self-locking device of plug in circuit breaker including the lock being slidably arranged on circuit breaker base and drives lock
The reset spring resetted is detained, the lock is equipped with opening compatible with the guide groove being arranged on circuit breaker base, works as promotion
When lock sliding, the opening on the lock can coincide with guide groove, and when decontroling lock, the reset spring drives lock multiple
Position, the opening are staggered with guide groove.
The utility model is further arranged: it is equipped with sliding slot on circuit breaker base, is equipped with sliding raised line in the side wall of sliding slot,
The lock includes upper lock button layer and lower lock button layer and the button for connecting upper lock button layer and lower lock button layer, and the sliding raised line is set
Between upper lock button layer and lower lock button layer.
The utility model is further arranged: being equipped with guiding axis in lower lock button layer, the reset spring is set on guiding axis.
The utility model has the advantages that when pushing lock sliding, the opening on the lock can coincide the utility model with guide groove,
So that breaker body is mounted on circuit breaker base by guide groove, and after being installed, when decontroling lock, the reset spring
Lock is driven to reset, the opening is staggered with guide groove, breaker body firm stable is mounted on circuit breaker base, is made
It obtains breaker body and circuit breaker base cooperation is more reliable and more stable.

Specific embodiment
It is done further in detail referring to self-locking device embodiment of the attached Fig. 1 to Fig. 4 to a kind of plug in circuit breaker of the utility model
It describes in detail bright.
A kind of self-locking device of plug in circuit breaker including the lock 2 being slidably arranged on circuit breaker base 1 and drives
The reset spring 3 that lock 2 resets, the lock 2 are equipped with opening compatible with the guide groove 11 being arranged on circuit breaker base 1
21, when pushing 2 sliding of lock, the opening 21 on the lock 2 can coincide with guide groove 11, so that breaker body passes through
Guide groove 11 is mounted on circuit breaker base, and after being installed, when decontroling lock 2, the reset spring 3 drives lock 2 to reset,
The opening 21 is staggered with guide groove 11, breaker body firm stable is mounted on circuit breaker base 1, so that breaker
Ontology cooperates more reliable and more stable with circuit breaker base 1.
It is wherein equipped with sliding slot 12 on circuit breaker base 1, is equipped with sliding raised line 13, the lock 2 in the side wall of sliding slot 12
Button 24 including upper lock button layer 22 and lower lock button layer 23 and connection upper lock button layer 22 and lower lock button layer 23, the sliding raised line
13 are placed between lock button layer 22 and lower lock button layer 23, so that lock 2 is more reliable and more stable in the sliding of circuit breaker base 1, under
Lock button layer 23 is equipped with guiding axis 25, and the reset spring 3 is set on guiding axis 25, after decontroling lock 2, so that lock 2 can
