Embodiment
Among Fig. 1, can see that electromagnetic trip device D comprises carriage 1 in self known mode, bearing bracket U-shaped armature 2, the two ends of armature constitute two polar surfaces, with impeller 3 collaborative works that pivot with respect to described armature 2, described impeller 3 can move to the magnetic circuit that is made of armature 2 and impeller 3 with closure above the described polar surfaces.This tripgear D also comprises tripping coil (trip coil) 4, installs around the sheath body 5 around magnetic circuit, and described pitch of the laps can react on the power of magnet 6 so that mobile impeller 3.This tripgear D also comprises the pin 7 that resets of impeller 3, and in order to acting on the plate 8 that is fixed on the impeller 3 and in order to the impact of damping reset force, described pin plays the effect of tripgear of the mechanism of the equipment that relay (relay) wherein is housed; And the back-moving spring 9 of impeller 3.
The back will illustrate the operation of a kind of like this tripgear D.When leaving standstill, there is not electric current in the coil 4, the magnetic flux that impeller 3 is generated by magnet 6 keeps putting leaning against on the armature 2.When electric current occurring in the coil 4, impeller 3 is opened when this electric current has reached the predetermined a certain value of balance between the magnetic torque that magnetic flux produced that is generated by the torque of spring 9 and magnet 6.
In Fig. 1 and 2, can see that carriage 1 comprises the first 10 of supporting armature 2 and magnet 6, and second portion 11, second portion and first are molded together, and constitute the sheath body 5 of coil 4.According to the present invention, carriage 1 comprises pin 7 bearings 12, is molded together with above-mentioned first 10 and second portion 11.This bearing 12 comprises first 13, is connected in sheath body 5 and is substantially perpendicular to described sheath body 5 to extend; Second portion 14 is substantially perpendicular to first 13 and extends; And third part 15, be substantially perpendicular to second portion 14 extensions and comprise the eyelet 16 that supply and marketing post 7 passes through.
The sheath body 5 of coil 4 comprises core body 17, by first 10 supporting of carriage 1 and comprise cannelure 18, in order to put 19 of two branches of armature 2U shape 19,20, the first 10 of carriage 1 is then passed by another branch 20 of U-shaped, and this branch 20 of U-shaped is held as the clamp 21,22 shown among Fig. 3 by means of two by carriage 1.Therefore carriage 1 abuts in by armature 2 internal end surface 23 armature 2 is located in the horizontal, make it to locate in the vertical by means of centering portion a, b, and make it on side direction, to locate by the size 25 of adjustment armature 2 and the inside dimension 27,28 of carriage 1.In Fig. 2, can specifically find out, for with respect to optimize copper material volume to constant volume, for the machinery between volume, the number of turns and the winding magnetic characteristic of optimizing coil windings and the equilibrium of function aspects, and in order to realize that with the function gap of a minimum armature is plugged in the reliability of carriage core body, the core body of carriage is designed on the side not carrying material.
The given shape 33 of carriage 1 makes the spring 9 can be by attaching.
Referring now to Fig. 4 to 6, as can be seen, according to a specific embodiment, the project organization of carriage 1 owing to its each given shape, has been guaranteed the tightness of relay and casing 34, particularly at 5 places highly at the top 3 of pin 7 bearings 12, itself and eyelet 36 collaborative works that are arranged on the casing 34.
Referring now to Fig. 7,8 and 9, as can be seen,, comprise the metal parts 37 that is welded on the armature 2 in addition according to the specific embodiment of tripgear D.Spring seat shape 38 obtains by a part of cutting and bending this metal parts 37.The latter can also make magnet 6 location by means of the shape of two lug 39,40, and magnet 6 is tightened up by welding, and the hinged backstop 41 in rear portion that can constitute impeller-plate sub-component.
According to another embodiment that is shown among Figure 10 and 11, the sub-component that is made of armature 2 and carriage 1 is fixed tightly on the mounting panel 42, and the latter is also as the lid that is bonded on the casing 43 on the described mounting panel 42.Realized tightness between mounting panel 42 and the casing 43.
Should be pointed out that the side can be improved reliability by adjusting dimension chain by the coil sheath body of place to go material.
Thereby the above-mentioned aperture 18 on the core body 17 limited by two opposed walls 44,45, the latter in order to two counter surfaces, 46,47 collaborative works of armature 2 above-mentioned branches 19.
Therefore the electromagnetic trip device (electromagnetic tripdevice) that comprises the carriage of carrying out the pin guiding is achieved by means of the present invention, promptly by means of the tightness of carriage and casing, comprise coil sheath body, supporting coil each connector, to tighten up each magnetic part of relay be magnet and armature, comprise a spring seat and formation pin with respect to the machinery of the sub-component of impeller that comprises relay and armature and the infrastructural frame on the function.
Because all these functions all realize by carriage, so this just makes tripgear can not be with its casing and be not with its mounting panel and carry out function.The reliability of relay is owing to the simplification of each dimension chain is enhanced, and this simplification is because carriage guiding pin and with respect to by armature with have magnetic sub-component that the impeller of its plate forms and come due to the positioning pin column.Described function sub-component comprises pin, sheath body, coil, each connector, armature, magnet, hinge pin backstop, impeller, plate and spring.
This carriage can be injected by plastics and make.
The present invention is specially adapted to various switch and various circuit breaker and is applicable to any other equipment that may adopt a certain tripgear.
The present invention is not limited to narrate and illustrated every embodiment naturally fully, and they just provide for purpose of illustration.
On the contrary, the present invention can extend with all technology peer of comprising described device with and various combination, if the latter is within spirit of the present invention.
