Abstract
The utility model discloses a novel circuit breaker tripping device. The novel circuit breaker tripping device includes a fixed iron core arranged on a positioning groove of a circuit breaker; the outer surface of the fixed iron core is sleeved with a bushing; the outer surface of the bushing is sleeved with a coil; the outer side of the coil is provided with a shielding cover; the shielding cover is arranged on the fixed iron core in a clamping manner; two ends of the coil are connected with a wiring board and a fixed contact respectively, wherein the wiring board is matched with the circuit breaker. According to the novel circuit breaker tripping device of the utility model, a shielding support in an existing tripping device is replaced by the shielding cover, and the shielding cover is arranged on the fixed iron core in a clamping manner, and therefore, the above split installation structure is more stable than existing riveting and welding structures. The novel circuit breaker tripping device has the advantages of simple structure, low cost, simple and fast production assembly, greatly-improved overall process and improvement of circuit breaker assembly speed.
Description
Technical field
The utility model relates to release design field, is specifically related to novel circuit breaker release.
Background technology
Circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition, and can close, in official hour, carry and cut-off the switching device of the electric current under abnormal loop condition (comprising short circuit condition).Therefore, circuit breaker has overload, short circuit and aftercurrent action protecting function conventionally.Circuit breaker is generally made up of contact system, arc quenching system, operating mechanism, release, shell etc.Release wherein, with (or composition entirety) that be connected on breaker mechanical, in order to release holding mechanism device that circuit breaker is disconnected automatically.
Existing circuit breaker, its release is generally the device that line concentration circle, terminal block, fixed contact and shield bracket are integrated, and link together by the technique such as riveted, welding, as shield bracket and terminal block by point welding process link together, shield bracket and fixed contact link together by riveted operation.But there is a lot of defects in such connected mode, cause complete machine circuit breaker in process of production, production process complexity, spot welding, riveted position easily come off, and not only affect the quality of complete machine, also can have influence on speed and the production efficiency of assembling simultaneously.
Utility model content
Technical problem to be solved in the utility model is to solve existing release riveted, low, the ropy problem of welded structure production efficiency.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of novel circuit breaker release, comprise the static iron core on the location notch that is arranged on circuit breaker, described static iron core outer surface is set with sleeve pipe, the outer surface of described sleeve pipe is set with coil, the outside of described coil is provided with radome, and described radome clamps and be arranged on described static iron core, and the two ends of described coil are connected with respectively terminal block and the fixed contact with circuit breaker adaptation.
In such scheme, the left and right two ends of described static iron core are respectively equipped with positioning boss.
In such scheme, described radome comprises left and right sidewall and rear shielding wall, be respectively equipped with and the arc groove of described positioning boss adaptation, and described arc groove is corresponding one by one with the location notch of described circuit breaker on described left and right sidewall.
In such scheme, the upper/lower terminal of described rear shielding wall is respectively equipped with rectangular recess.
The utility model, the downside of static iron core is fixed on the location notch of circuit breaker, and upside is fixed by radome, now, sleeve pipe is just in time installed between the two side of location notch, simultaneously, release lid on circuit breaker is fixedly installed on radome upper end on circuit breaker, thus the tripping mechanism of complete.In this device, radome has been replaced the shield bracket in existing release, and is arranged on release by the mode clamping, this partial installation structure, and than existing riveted, Welding Structure mode, structure is more stable.
The utility model, adopts novel circuit breaker release, simple in structure, with low cost, produces assembling simple and fast, has greatly improved integrated artistic, has also improved the assembling speed of circuit breaker simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the decomposing schematic representation of Fig. 1 in the utility model;
Fig. 3 is schematic diagram when release is arranged on circuit breaker in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1 to Figure 3, the utility model provides a kind of novel circuit breaker release, comprise the static iron core 3 on the location notch 2 that is arranged on circuit breaker 1, static iron core 3 outer surfaces are set with sleeve pipe 4, the outer surface of sleeve pipe 4 is set with coil 5, the outside of coil 5 is provided with radome 6, and radome 6 clamps and be arranged on static iron core 3, and the two ends of coil 5 are connected with respectively terminal block 7 and the fixed contact 8 with circuit breaker 1 adaptation.
The left and right two ends of static iron core 3 are respectively equipped with positioning boss 31.
Radome 6 comprises left and right sidewall and rear shielding wall, be respectively equipped with and the arc groove 61 of positioning boss 31 adaptations, and arc groove 61 is corresponding one by one with the location notch 2 of circuit breaker 1 on left and right sidewall.
The upper/lower terminal of rear shielding wall is respectively equipped with rectangular recess 62.The design of this rectangular recess 62 is convenient to install, and has also saved use material simultaneously.
The utility model, the downside of static iron core is fixed on the location notch of circuit breaker, and upside is fixed by radome, now, sleeve pipe is just in time installed between the two side of location notch, simultaneously, release lid on circuit breaker is fixedly installed on radome upper end on circuit breaker, thus the tripping mechanism of complete.In this device, radome has been replaced the shield bracket in existing release, and is arranged on release by the mode clamping, this partial installation structure, and than existing riveted, Welding Structure mode, structure is more stable.
The utility model, adopts novel circuit breaker release, simple in structure, with low cost, produces assembling simple and fast, has greatly improved integrated artistic, has also improved the assembling speed of circuit breaker simultaneously.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
