Abstract
The invention relates to a circuit breaker in which a manual command organ (1) acts upon at least one movable contact arm (4) via a switch latch, said contact arm representing a pair of contacts (5, 6). The switch latch is configured as a zone of latching between a latch (2) and a trip lever (3) in a kinematic system. According to the invention, a spacer element (7) provides a decoupling distance (8) in the direction in which due to the kinematic system a dynamic force is possible due to a switching impulse once an engagement in said direction is brought about.
Description
Technical field
The present invention relates to a kind of circuit breaker, one of them manual operating mechanism acts on the contact arm of at least one motion by a switch lock, it is right that this contact arm constitutes a contact, and described switch lock constitutes the meshing point in the kinematics between a ratchet and release lever.Switch lock has the meshing point in the kinematics between ratchet and release lever.
Background technology
The contact impact that may cause of meeting is propagated by switch lock as shock wave when connecting.This can cause threading off and undesirable disconnection in the engagement of sensitivity.Especially when collision connection or impact type connection, be difficult to avoid this shock wave in the newly-designed switch lock.So far, people attempt to obtain in fact enough dampings by drawing back space length usually between impulse source and meshing point.
Summary of the invention
The objective of the invention is to develop a kind of circuit breaker, also can keep engagement reliably even it is subjected to impact load.
Above-mentioned purpose realizes by a kind of circuit breaker.In this circuit breaker, a manual operating mechanism acts at least one by a switch lock and constitutes on the right motion contact arm in a contact, and wherein, described switch lock constitutes the meshing point in the kinematics between a ratchet and release lever.In view of the above, when meshing on the direction that may be subjected to the effect of switching surge power based on kinematic design, a spacing part causes a throw-off distances along this direction.This distance can be especially form between the bearing on the release lever during in engagement with it at ratchet, spacing part rollback subsequently, thus the buffering area of a disengagement is provided, can in this buffering area, eliminate impact gradually, thereby ratchet is come off from its release lever.
Circuit breaker especially can be established a rotating manual operating mechanism, and it acts on the motion contact arm by switch lock, and it is right that a motion contact arm and a fixed contact constitute a contact.This switch lock can be further as design in such a way common in the line protection switch, that is, and when the ratchet on leaning against release lever is thrown off, because the location independent ground of release and manual operating mechanism works contact so disconnection.In this circuit breaker, when ratchet and release lever meshed on the direction that may be come from the effect of motion contact force based on kinematic design, a spacing part caused a throw-off distances along this direction.
This circuit breaker can especially have a switch lock, and its ratchet is at the supporting indirect of a position changeable or guiding movement contact arm directly, and its release lever is contained in the bearing of a fixed-site and the support motion contact arm.This ratchet can further be connected in the supporting of another position changeable with the connecting rod that is used for manual operating mechanism.Therefore, the spacing part is a profile dish advantageously, and it is designed to, and release lever can be placed a determining deviation place at the open position of the switch lock by the manual operating mechanism operating, then retreats into ratchet profile place at on-position.Thus, guarantee the spacing effect of spacing part and guarantee that in simple mode it is at the on-position rollback in simple mode.
The profile dish is rotatably supported in the pawl-bearing that is used for connecting rod, and handles by stirred the pusher dog that is located on the profile dish by connecting rod.
Description of drawings
Can further specify the present invention by the embodiment that schematically illustrates in the accompanying drawing below, in the accompanying drawing:
Fig. 1 illustrates the circuit breaker that is in open position;
Fig. 2 illustrates the circuit breaker shown in Figure 1 that is in on-position;
Fig. 3 illustrates the important composition member of circuit breaker shown in Fig. 1 and 2 with the form of explosive decomposition figure.
Embodiment
Circuit breaker shown in Figure 1 has operating mechanism 1 and a switch lock on the other hand, what can see in the drawings about switch lock is meshing point between ratchet 2 and release lever 3, wherein contact arm 4 is hinged on the ratchet rotationally and a contact 5 is arranged, and it is right that contact 5 cooperates fixed contact 6 work and constitutes a contact with it.By rotation manual operating mechanism 1 engagement from the open position to the on-position time, a spacing part that leans against on the ratchet causes a throw-off distances 8 along direction 9, and on direction 9, switch lock may be subjected to the effect of switching surge power based on kinematic design.Represent common contact and switch spring with compression spring 10 here.Normally the releasing device of a magnetic release and a thermal release does not here all illustrate for the purpose of view is clear.In the embodiment shown in fig. 1, rotating manual operating mechanism 1 is by connecting rod 11 be connected with motion contact arm 4 by switch lock.Release lever 3 is contained in the bearing 12 of a fixed-site and at position of engagement support motion contact arm 4.Connecting rod 11 is connected in the supporting 14 of a position changeable with ratchet 2.In the present embodiment, the spacing part is pressed the principle design of profile dish.As shown in Figure 1, lean against on the release lever with its profile, and therefore when the profile dish retreats into ratchet profile place, cause a throw-off distances 8 at on-position at open position profile dish.
This spacing part that is designed to the profile dish is bearing in the bearing 14 of ratchet with connecting rod 11 rotationally.The profile dish has pusher dog 15 in this embodiment, and the profile dish is handled by connecting rod 11 by it.This manipulation also can be finished by the structure division of shell or lid.
In pressing embodiment illustrated in figures 1 and 2, the spacing part 7 that is designed to cam disc is realized by Fig. 2 recessed profile in the meshing point zone by the profile of Fig. 1 protrusion with by one by one.
Fig. 3 is illustrated in circuit breaker important component set among Fig. 1 and 2 by the mode of exploded view, so that can fully show the original looks of the original overlapping member that puts together.Connecting rod between the supporting 13 of the bearing 12 of fixed-site and position changeable is represented with 16.
