Abstract
The utility model relates to a tripping device which comprises a base, an upper cover connected with the upper part of the base, a coil framework arranged in the base, a coil winding, a magnet conducting plate passing through the coil winding and the coil framework, an armature, a permanent magnet at the rear end of the magnet conducting plate, a spring arranged between the coil framework and the armature, and a push rod arranged above the armature, wherein the rear end of the magnet conducting plate is in the shape of a swallow tail, the permanent magnet is arranged at the swallow tail, a projection is formed at the upper front part of the swallow tail and forms a rotation pivot of the armature. The tripping device has small damage to an operative pole face in operation and stable current.
Description
Technical field
The utility model relates to the electrical control field, a kind of specifically release.
Background technology
Release operating current stability is the most important performance parameter that will reach of release manufacturing and production.Under the prerequisite that the pulling force of armature does not change, cause that variation has taken place the magnetic flux that basic reason that operating current changes can be described as by the work pole-face.Because magnetic flux changes, so operating current is just ensued variation.The reason that causes magnetic flux to change mainly contains: one, because permeability magnetic material is subjected to various stress influence, causes the magnetic conduction situation to change and cause magnetic flux and change; Its two, the magnetic flux density of permanent magnet changes and causes flux change; Its three, the effective area of the pole-face of working exactly changes and makes the magnetic flux of whole magnetic circuit that variation arranged.With regard to the existing release of doing when predecessor company, the most general maximum problem is the third, promptly belongs to the work pole-face and changes and produced operating current variation, the wild effect of just saying at ordinary times.
The reason that existing release work pole-face changes is except being to have particle to enter the work pole-face to cause pole-face destroys, be exactly in addition when release designs intrinsic defective, pivot point when the edge of existing exactly release magnetic conductor work pole-face when action is exactly armature movement, so all the time can be in the process of action in the work continuous generation friction in pole-face place, exist friction just to mean the destruction of pole-face, this is a design deficiency of existing release.
Existing release will all will be connected with the electric of zero sequence current mutual inductor and wiring board in use, and connected mode all is to adopt directly winding two ends lead-out wire with magnetizing coil as connecting line, is welded to connect with the mode of soldering.Because the winding wire of winding sometimes carefully to having only 0.03mm, causes winding wire to be easy to broken string and release can't be used.Winding leads is long and soft, is easy to form tangled up and knotted and release is scrapped, and this class problem is the common problem that often occurs in the production use.
Existing release in process of production, the operation that spring is installed on armature and the strutting piece is the minimum operation of operating efficiency, because employing is the dicyclo extension spring, often appears in the process of hook spring, spring collude the end place with the working face scratch of armature and part is scrapped, cause damage.In mounted elastically operating process, need in addition earlier spring to be positioned over the palm of the hand, go to take spring to carry out hand assembled with hand again, the heat of human hands has brought certain thermal stress for the magnetic conduction part in the whole process, the greasy dirt and the steam that also can produce human body on the surface of magnetic conduction part condense, and cause secondary pollution to part.This procedure wants full qualification with the skilled worker to decide operating efficiency, and the skilled worker of this procedure needs the cultivation of half a year at least just to reach the operation requirement, even the skilled worker at most also can only assemble 1500～2000 8 hours every days.Formed very high labour cost and very low production efficiency, the quality condition of operation depends on employee's technical ability fully, so quality stability is poor.
The utility model content
The purpose of this utility model is for providing little to work pole-face destruction in a kind of course of work, the release that operating current is stable.
The technical scheme that realizes the foregoing invention purpose is as follows:
Release, comprise pedestal, the loam cake that is connected with pedestal top and be located at coil rack, the coil windings in the pedestal, the magnetic conductive board that passes coil windings and coil rack, armature, magnetic conductive board rear end permanent magnet, be located at the spring between coil rack and the armature and the push rod of armature top, the rear end of described magnetic conductive board is swallow-tail form, the dovetail place is provided with permanent magnet, the upper end, the place ahead of dovetail has projection, and this convexes to form the pivot point of armature.
The described spring of being located between coil rack and the armature is a torsion spring.
Described magnetic conductive board is divided into left and right two magnetic conductive boards, and left and right magnetic conductive board fits together, and the rear portion forms swallow-tail form.
Described coil rack is provided with two pins, and the two ends of described coil windings are connected respectively on two pins.
Be connected by buckle between described loam cake and the pedestal.
The utility model release is located at the magnetic conductive board rear portion by the pivot point with armature, make release in most times of action, pivot point during with armature movement separates with the work pole-face, just to the at last extremely short stage of last armature when wanting adhesive just allow armature contact with the pole-face of working, though so also there is the ruined possibility of working face, but be to have reduced the ruined degree of working face greatly, the stability of operating current just is improved like this.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, release, comprise pedestal 1, the loam cake 2 that is connected with pedestal 1 top and be located at coil rack 3, the coil windings 4 in the pedestal 1, the magnetic conductive board 5 that passes coil windings 4 and coil rack 3, armature 6, magnetic conductive board 5 rear ends permanent magnet 7, be located at the spring 8 between coil rack 3 and the armature 6 and the push rod 9 of armature 6 tops, the rear end of described magnetic conductive board 5 is swallow-tail form, the dovetail place is provided with permanent magnet 7, the upper end, the place ahead of dovetail has projection 10, and this projection 10 forms the pivot point of armature.
The described spring of being located between coil rack and the armature is a torsion spring.Original dicyclo extension spring be modified into a torsion spring substitute, only need when armature and spring assembling simple just place can, do not need complicated hook to move.Just reduce the spring assembly difficulty greatly after improving, improved efficiency of assembling, and avoided in mounted elastically process, giving easily the work pole-face of magnetic conduction part to bring the problem of destruction simultaneously.
Described magnetic conductive board is divided into left and right two magnetic conductive boards, and left and right magnetic conductive board fits together, and the rear portion forms swallow-tail form.Magnetic conductive board is divided into left and right two, makes magnetic flux line flow better effects if from left to right.
Described coil rack is provided with two pins 11, and the two ends of described coil windings are connected respectively on two pins.By setting in advance the pin of two wickings, thereby the original lead-in wire broken string and the problem of knotting have been avoided.
Be connected by buckle between described loam cake and the pedestal.
