Technical Field

[0001] The utility model belongs to the technical field of circuit breakers, and in particular relates to a yoke assembly. Background Art

[0002] The circuit breaker yoke is usually made of stacked silicon steel sheets. This material has good magnetic conductivity and low eddy current loss, and is suitable for use in electromagnetic systems. Silicon steel sheets (also called electrical steel sheets) are a special steel material specially used for electromagnetic equipment such as motors and transformers. The surface is coated with an insulating layer to reduce eddy current losses and improve efficiency.

[0003] For example, the Chinese patent with publication number CN212161740U discloses a circuit breaker yoke. The technical problem to be solved by the utility model is to provide an integrated circuit breaker yoke with low cost, simple structure and high consistency of finished products. The technical solution adopted by the utility model: including a yoke body and a yoke static contact, the yoke body and the yoke contact part are integrally stamped, the upper end of the yoke body extends vertically outward to form an upper yoke plate, the lower end of the yoke body extends vertically outward to form a lower yoke plate, the upper yoke plate is provided with a first semicircular notch, the lower yoke plate is provided with a second semicircular notch, the yoke body is provided with a snap-on protrusion, and the lower yoke plate is provided with a triangular snap-on. The advantages of the utility model are that the static contact, the static contact point and the yoke are all integrally stamped, which reduces the process and reduces the production cost, reduces the temperature rise caused by riveting or welding, and improves the consistency of the performance of the finished product.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the device uses a triangular bayonet and a clamping protrusion to clamp the yoke on the plastic part, and repeated disassembly and installation may cause wear and failure of the clamping part. In view of this, we propose a yoke assembly. Utility Model Content

[0009] Two sliding bars, both of which are slidably installed in the limiting grooves, and the two sliding bars are respectively located on one side of the first rectangular bar and the second rectangular bar. Limiting columns are fixedly installed at both ends of the sliding bar, and the limiting columns are slidably connected with the limiting grooves.

[0011] In this technical solution, when the yoke body needs to be disassembled, through the provided driving assembly, then under the action of the rebounding force of a plurality of first springs, the two sliding bars slide and approach each other. Subsequently, the two sliding bars respectively drive the four limiting columns to slide and approach each other. When the four limiting columns are respectively disengaged from the four through holes, the operator can pull the yoke body, and the yoke body drives the second rectangular bar and the first rectangular bar to disengage from the limiting groove, and at this time, the disassembly of the yoke body is completed;

[0012] When the yoke body needs to be installed, through the provided driving assembly, then place the yoke body on one side of the fixing plate. Subsequently, the first rectangular bar and the second rectangular bar are both inserted into the limiting groove. Through the provided driving assembly, the two sliding bars can be driven to slide. At the same time, a plurality of first springs are compressed and contracted. The two sliding bars respectively drive the four limiting columns to slide, and the four limiting columns are respectively inserted into the four through holes, so that the positions of the first rectangular bar and the second rectangular bar can be fixed. At this time, the position of the yoke body is fixed, and the yoke body can be replaced. The operation is convenient, and no tools are required. After repeated replacement, it may be firmly fixed.
