Description
Technical Field
The utility model belongs to the technical field of the circuit breaker accessory, specifically speaking relates to a circuit breaker tripping device.
Background
The breaker is a switching device which can connect, bear and break current under normal circuit conditions, and can also connect, bear and break current for a certain time under specified abnormal circuit conditions (overload and short circuit); the circuit breaker generally comprises a tripping mechanism, an electromagnetic system, a thermal tripping system and a conductor part, wherein the tripping mechanism and the electromagnetic system are conducted through a movable contact and a fixed contact. When the problems of overload, short circuit and the like occur, the electromagnetic system drives the tripping mechanism to act so as to separate the movable contact and the fixed contact from each other, thereby realizing the disconnection in an abnormal state.
The prior tripping mechanism has the following defects in use.
A connecting rod is assembled between a handle and a jump buckle of an existing tripping mechanism, one end of the connecting rod is sleeved at the eccentric position of the handle, the other end of the connecting rod is sleeved at the intersection of the jump buckle and a lever, and the push-pull jump buckle and the lever are achieved through back and forth movement of the connecting rod to achieve linkage. Therefore, there is a need for a circuit breaker trip mechanism.
Disclosure of Invention
To above problem, the utility model provides a circuit breaker tripping device jumps and detains and link more stably between the lever, and the dropout is more reliable.
In order to solve the above problems, the utility model adopts the following technical proposal.
The utility model provides a circuit breaker tripping device, includes the handle, with the jump of handle linkage detain and with jump detain the lever of rotating the connection, be provided with the connecting rod on the handle, this connecting rod one end cartridge is detained in jumping, jump detain one side and take shape flutedly, integrated into one piece has the ejector pin in this recess, the cooperation department of lever and ejector pin is provided with the rake.
Preferably, a first torsion spring is arranged between the jump buckle and the lever, and a second torsion spring is arranged on the inner side of the lever.
Preferably, one side of the lever is provided with a middle plate, and the lower side of the middle plate is provided with a movable contact.
Preferably, a contact spring is provided between the intermediate plate and the lever.
Preferably, one end of the connecting rod is in interference fit with the jack on the jump buckle.
Advantageous effects
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses well connecting rod one side suit is in the eccentric position of handle, and the opposite side inserts to jump and detains and interference fit, jumps to detain the inboard integrated into one piece that corresponds and has the ejector pin, and handle pulling connecting rod drives and jumps to detain the action, through the rake on the ejector pin promotion lever, realizes that synchronous action reaches the dropout, jumps to detain and links more stably between the lever, and the dropout is more reliable.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, it is the utility model discloses a circuit breaker tripping device's of preferred embodiment structure sketch map, including handle 7 in this embodiment, jump with the linkage of handle 7 and detain 1 and with jump and detain 1 and rotate lever 2 of being connected, be provided with connecting rod 8 on the handle 7, this connecting rod 8 one end cartridge is detained 1 in jumping, jump 1 one side is formed flutedly, and integrated into one piece has ejector pin 11 in this recess, lever 2 is provided with rake 21 with ejector pin 11's cooperation department, and connecting rod 8 one side suit is in the eccentric position of handle 7, and the opposite side inserts to jump and detain 1 and interference fit, and the inboard integrated into one piece that jump detain 1 corresponds has ejector pin 11, and handle 7 pulling connecting rod 8 drives the action of jumping detaining 1, promotes rake 21 on lever 2 through ejector pin 11, realizes that the synchronous action reaches the dropout, and the linkage is more stable between jump detain 1 and the lever 2, and the dropout is more reliable.
In this embodiment, a first torsion spring 3 is disposed between the jump buckle 1 and the lever 2, a second torsion spring 4 is disposed inside the lever 2, and the jump buckle 1 and the lever 2 have a reset function through the action of the first torsion spring 3 and the second torsion spring 4.
In this embodiment, one side of the lever 2 is provided with an intermediate plate 6, a moving contact is arranged on the lower side of the intermediate plate 6, and the lever 2 drives the intermediate plate 6 to drive the moving contact to move synchronously when moving, so that the lever has the conditions of opening and closing.
In this embodiment, a contact spring 5 is provided between the intermediate plate 6 and the lever 2, and the contact spring 5 provides a return condition between the intermediate plate 6 and the lever 2.
In this embodiment, 8 one end of connecting rod and the jack interference fit on the jump knot 1 guarantee that 8 difficult follow jumps and detain 1 and deviate from, promote the stability of handle 7 and jump knot 1 linkage, and both assembles more firmly.
The above description is for further details of the present invention, and it is not assumed that the embodiments of the present invention are limited to these descriptions, and it is obvious to those skilled in the art that the present invention can be implemented by a plurality of simple deductions or replacements without departing from the concept of the present invention, and all should be considered as belonging to the protection scope defined by the claims submitted by the present invention.
