Description
Technical field
The present invention relates to a kind of round contact.
Background technology
In electric switching technique, the circle contact for example is used for connecting breaker.Round contact is made of fingertip herein, and described fingertip is pressed onto on the coupling bar of feeding mechanism by means of contact top-pressure mechanism top.Described fingertip is constructed to such an extent that can stretch out above the length of coupling bar and is held in this section columniform joint.Described columniform joint can be inserted in the opening that is formed by described fingertip.Described contact top-pressure mechanism is pressed described fingertip towards joint with towards the coupling bar top when inserting joint.The circle contact is because its cylinder open is also referred to as the tulip contact equally.
The Another application field of circle contact is connector technology or the sliding technology of inserting, wherein with the tulip contact as the plug type contact.This is particularly useful for circuit breaker (MCCB-Molded Case Circuit Breaker(breaker of plastic casing)) contact, described circuit breaker is inserted technical battery to receive energy supply online by sliding.
Circuit breaker design must keep rated current to reach larger from 10A to 100A and close when overload current or short circuit current.The single mutually usually independent break-make of electric current is for example in so-called utmost point box.Be provided with movable contact and fixed contact in described utmost point box, described movable contact can mechanical separate or engage with fixed contact and be used for cutting off or making current.Electric switch can be constructed to get the single phase of break-make or also can a plurality of phases of break-make for this reason.
On circuit breaker for example was connected to power supply network electricly, the contact that must guarantee circle contact or tulip contact was not up to certain current value, separate when being so-called current carrying capacity.The separation of contact or unlatching can cause the generation of electric arc and therefore cause the degeneration of plug type contact.The danger that separates is, play unlatching (electric current-narrow slit-Li (Strom-Enge-Kraft)) because magnetic force has usually at contact, described electric current-narrow slit-masterpiece is used in the coupling part of round contact or tulip contact.In order to compensate these opening forces spring element of usually packing on the tulip contact, described spring element keeps together described fingertip.
Show, the bus-bar that is connected on the coupling bar of tulip contact is influential to the magnetic force of the fingertip of contact.Described magnetic force can or advantageously or detrimentally exert an influence to current carrying capacity, and said magnetic force is made of two parts: (1) is played the electric current-narrow slit of unlatching effect-Li and (2) at described contact and can be risen and open or the Lorentz force of closure function.For the current carrying capacity that improves round contact at this advantageously, realize having the structure of the Lorentz force of high as far as possible closure.
Round contact or the tulip contact of structural shape up to now have fingertip, and described fingertip is furnished with the contact top-pressure mechanism.Common described fingertip is enclosed within on the coupling bar and can rotates freely thereon.Therefore can not realize the orientation of described fingertip specific or expectation on described coupling bar.
