Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a frame circuit breaker. Background Technique

[0002] The frame circuit breaker, also known as the universal circuit breaker, is a mechanical switching electrical appliance that can connect, carry, and break the current under normal circuit conditions, and can also connect, carry for a certain time, and break the current under specified abnormal circuit conditions. The frame circuit breaker is used to distribute electric energy and protect the line and power supply equipment from overload, undervoltage, short circuit, etc. This kind of circuit breaker generally has a steel frame, and all parts are installed in the frame. It has a large capacity, can be equipped with various function trip units and more auxiliary contacts, and has a high breaking capacity and thermal stability, so it is often used in places requiring high breaking capacity and selective protection.

[0003] The existing frame circuit breaker includes a main body, side plates, and a mounting base. When installing the existing mounting base, it needs to be manually held and aligned with the mounting holes on the side plates to complete the installation. Since the mounting base has a certain weight, the above installation method is rather inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a frame circuit breaker to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a frame circuit breaker, including a frame circuit breaker main body, side plates are assembled on both sides of the frame circuit breaker main body, a connecting part is integrally formed on the side plates, the connecting part is in a "U" - shaped structure, and a cavity is formed inside the connecting part. The frame circuit breaker main body further includes a mounting base, and contact parts for inserting into the cavity to form a limit abutment are extended on both sides of the mounting base.

[0006] Preferably, the width of the cavity is greater than the thickness of the contact part of the mounting base.

[0007] Preferably, corresponding mounting holes are opened on both the connecting part and the contact part.

[0008] Preferably, when the contact part abuts against the lower end of the connecting part, the mounting holes of the two overlap.

[0009] Compared with the prior art, the beneficial effect of the utility model is that when assembling, the mounting base is placed on the connecting part, and the connecting part limits the mounting base, further reflecting the effect of convenient installation. Brief Description of the Drawings

[0015] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0016] Please refer to Figures 1-3 A frame circuit breaker, including frame circuit breaker main body 10, frame circuit breaker main body 10 both sides are equipped with side plate 102, the side plate 102 is integrally formed with connecting part 1021, the connecting part 1021 is "N" shape structure and is formed with cavity 10211 in connecting part 1021, frame circuit breaker main body 10 further includes a mounting seat 103, the mounting seat 103 both sides are extended and are provided with the contact part for inserting cavity 10211 and forming the limiting abutment, when assembling, the mounting seat 103 is placed in connecting part 1021, and the mounting seat 103 is limited by connecting part 1021, further embodies the effect of convenient installation.

[0017] Specifically, the width of the cavity 10211 is greater than the thickness of the contact part of the mounting seat 103, and the contact part is interference fitted by using the width of the cavity 10211 itself, so that the assembly of the two is more firm.

[0018] Specifically, the connecting part 1021 and the contact part are provided with corresponding mounting holes, and the connecting part 1021 and the contact part are fixed by mounting holes cooperating with bolts.

[0019] Specifically, the mounting holes of the contact part and the connecting part 1021 overlap when the contact part abuts the lower end of the connecting part 1021, and the design of this structure makes the installation more convenient and fast.

[0020] ​​It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
