The open a kind of circle contact of the present invention, described round contact comprises the fingertip that at least two have fan-shaped cross section, and there is feeding mechanism and at least one contact top-pressure mechanism of coupling bar, wherein said at least two fingertips are pressed towards described coupling bar top by described contact top-pressure mechanism, and wherein said at least two fingertips are arranged on described coupling bar un-rotatably.
Description
Technical field
The present invention relates to a kind of circle contact.
Background technology
In electric switching technique, circle contact is such as connecting breaker.Round contact is made up 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 constructs can extend over the length of coupling bar and hold columniform joint in this section.Described columniform joint can be inserted in the opening formed by described fingertip.Described contact top-pressure mechanism presses described fingertip when inserting joint towards joint with towards coupling bar top.Circle contact is also referred to as tulip contact equally due to its cylinder open.
The Another application field of circle contact is connector technology or sliding inserts technology, wherein using tulip contact as plug type contact.This is particularly useful for circuit breaker (MCCB-MoldedCaseCircuitBreaker(breaker of plastic casing)) contact, described circuit breaker is received on energy supply system by Hua Cha technical battery.
Circuit breaker design must keep rated current from 10A to 100A and larger and close when overload current or short circuit current.The single usual break-make separately mutually of electric current, such as, in the box of so-called pole.In the box of described pole, be provided with movable contact and fixed contact, described movable contact can be separated or engage for cutting off or making current by machinery with fixed contact.Electric switch can construct to obtain the single phase of break-make or also can the multiple phase of break-make for this reason.
When circuit breaker is electrically connected on such as power supply network, must ensure that the contact of circle contact or tulip contact is not being separated up to when certain current value, i.e. 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 be separated is, because magnetic force has usually play unlatching (electric current-narrow slit-Li (Strom-Enge-Kraft)) on contact, described electric current-narrow slit-masterpiece is used in the coupling part of round contact or tulip contact.On tulip contact, usually load spring element in order to compensating these opening forces, described fingertip keeps together by described spring element.
Show, being connected to the magnetic force of the bus-bar on the coupling bar of tulip contact on the fingertip of contact has impact.Described magnetic force can or advantageously or deleteriously have an impact to current carrying capacity, and said magnetic force is made up of two parts: (1) plays the Lorentz force that unlatching or closure function can be played in the electric current-narrow slit-Li of unlatching effect and (2) on described contact.In order to improve the current carrying capacity of round contact at this advantageously, realize the structure with closed Lorentz force high as far as possible.
Round contact or the tulip contact of structural shape up to now have fingertip, and described fingertip is furnished with contact top-pressure mechanism.Usual described fingertip to be enclosed within coupling bar and can to rotate freely thereon.Therefore described fingertip specific or orientation of expecting on described coupling bar can not be realized.
