Description
Technical field
The present invention relates to bring the assembly in the breaker type electrical appliance into, it mainly is made up of mechanical lock and temperature-sensitive element.
Background technology
Lock is connected at least one pair of fixed contact and moving contact, with mobile each moving contact that is delivered to of a joystick, make it respectively be bearing on the fixed contact and and said fixed contact at a distance of moving between two settling positions of certain distance.This lock comprises movable contact seat and tripping mechanism, just in case be short-circuited in the protective circuit or the electricity overload, can act on said release, thereby through the contact base upset opened circuit in the contact.
The temperature-sensitive element that these electrical equipment are furnished with is based on a kind of bimetallic element; It is connected in circuit; Just in case transship, tripping mechanism/contact base assembly is pivotally overturn, said bimetallic element is installed between moving contact and the terminal; Said terminal is connected in connector, and said connector is connected in protector.
Until now, the fixed part of temperature-sensitive element and the connection between the movable member are generally implemented by flexible cord.Like this, one of end of bimetallic element for example is connected in terminal by means of flexible cord, and the other end still is connected in moving contact through flexible cord.Cause that thus temperature-sensitive element is not a rigidity, like this, when assembled product, little practical.
In fact, the flexible cord solution is not quite favourable economically, both because it makes the complicated or obstruction assembly automation of assembly automation, again because the cost of flexible cord own is high.
Summary of the invention
Therefore, the present invention is intended to remedy the defective relevant with using flexible cord.
Characteristic of the present invention mainly is: bimetallic element is connected in moving contact rigidly; It carries out single degree of freedom formula conduction with binding post and is connected.
The device that lock/temperature-sensitive element sub-assembly forms is greatly simplified, and the reducing of complicated degree obviously reduces cost.Because the relative rigidity of the assembly that so obtains can or can be simplified the installation automation at least, so more effective.
The member of moving contact, lock and the member of temperature-sensitive element for example form the new-type element of expansion and processing now when assembling, like this, with respect to current installation method, removed some operations.
Novel component also makes lock rotate in inside, no longer be responsible for by terminal box---and all be to be responsible for until now, like this, can break away from some problem of alignment tolerance when making lock by terminal box.
Of the back, this structure also can change the shape of bimetallic element, and can simplify adaptive for the various different sizes of the electrical equipment that said temperature-sensitive tripping mechanism is installed of temperature-sensitive tripping mechanism.
The arm that extend on the plane vertical with the pivot of tripping mechanism/contact base assembly from the edge prolongs the terminal of temperature-sensitive element; Especially obtain to rigidly fix; Its free end has contact chip; Conductive connecting element pivots around said contact chip with this assembly, and said conductive connecting element conducts electricity with bimetallic element and is connected, and said bimetallic element is connected in said contact base.
Therefore, the terminal and the connection between the bimetallic element of connector are carried out rotatably, and this does not influence the compactedness of assembly, can regard assembling single part as.
Preferably, this conductive connecting element is a rigidity, and is connected in one of end of bimetallic element.
Mechanically, it itself is the part of rigidity that contact base, said electric connecting part and bimetallic element preferably form one, and it can pivot with respect to terminal, thereby can pivot with respect to the terminal box of electrical equipment, and said terminal y arranges regularly.
According to a possibility, moving contact also is fixed in one of end of bimetallic element on the one hand rigidly, is fixed in contact base on the other hand rigidly.
In a word; The end that prolongs the rigid arm of terminal forms a pivot, around this pivot knuckles, be the assembly that constitutes by contact base, conductive member, bimetallic element and moving contact on the one hand; Be tripping mechanism on the other hand, said tripping mechanism can be independent of said assembly and pivot.
According to this supposition, because the rigidity that moving contact/contact base connects, the compensation of wearing and tearing can not be implemented at the moving contact place, but can be implemented by fixed contact.
For guaranteeing the compactedness of this assembly, bimetallic element preferably takes the shape of the letter U, and each all is fixed on the free end of the different branching portions of U link and moving contact.
This shape is favourable, because said link and contact are fixed near the pivot, makes the base portion of U keep free, therefore, and said base portion deformability.
For making bimetallic element fulfil its function, tripping mechanism has a reinforcement, and said reinforcement forms a driving member, and its free end is arranged near the base portion of U, and is configured as when bimetallic element is out of shape, and said base portion promotes said driving member.
In case bimetallic element is passed through by the overload current that surpasses certain limit, the distortion of said bimetallic element just is enough to promote driving member, that is to say, tripping mechanism is pivoted, and unclamps lock in a conventional manner.
According to a possibility, terminal is prolonged by the electric arc guide plate.
In many one type of prior art syringe, this electric arc guide plate is fixed near one of end of bimetallic element, is positioned at it and is connected in the terminal place that jockey is furnished with by flexible cord.
Form the pivot of terminal, electric arc guide plate and lock simultaneously by sheet material cutting and the folding single rigid element that forms, be easy in the terminal box of its assembly that constitutes with lock and bimetallic element, locate.
The invention still further relates to the for example circuit and the personal protection electrical equipment of standardization circuit breaker type, it has the assembly that is made up of mechanical lock and for example above-mentioned temperature-sensitive element.
