Description
Technical field
This utility model relates to a kind of contact system, particularly relates to a kind of contact system being easily installed for breaker of plastic casing.
Background technology
Breaker of plastic casing is as the branch stage electrical power distribution apparatus of distribution system, and along with the needs constantly increased with centralized power distribution of net capacity, its breaking capacity of system requirements is more and more higher, so the extensive use in breaker of plastic casing of current-limiting type structure of contact terminal. At present, traditional breaker contact system ubiquity structure is complicated, installs inconvenient and relatively costly shortcoming.
Utility model content
The purpose of this utility model is in that to provide a kind of breaker contact system being easily installed, and it has the advantages that simple in construction, cost are low and are easily installed, to solve the problems referred to above that in prior art, dropproof breaker contact system exists.
For reaching this purpose, this utility model by the following technical solutions:
A kind of breaker contact system being easily installed, it includes rotating shaft and moving contact, wherein, described rotating shaft has the containing cavity running through whole rotating shaft, described rotating shaft is equipped with steady pin in described containing cavity, one end of described moving contact is rotatablely arranged on described steady pin, and described moving contact is arranged below removable pin in described steady pin, described steady pin is connected to the support component for being fixed on by whole contact operating mechanism on circuit breaker base, the both sides of described support component are provided with the contact torsion spring being arranged in outside described steady pin, one end of described contact torsion spring is resisted against in described rotating shaft, the other end is resisted against on described removable pin.
Especially, described support component includes fixing plate, and the both sides of described fixing plate have upwardly extended two blocks of side plates, and described two blocks of side plates are all connected on described steady pin.
Especially, described moving contact being provided with a lobe, described removable pin is installed in described lobe.
The beneficial effects of the utility model are, the breaker contact system being easily installed described in compared with prior art is not only simple in structure, cost is low; And it is easy for installation.

In figure:
1, rotating shaft; 2, moving contact; 3, steady pin; 4, lobe; 5, removable pin; 6, contact torsion spring; 7, fixing plate; 8, side plate.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of breaker contact system being easily installed includes rotating shaft 1 and moving contact 2, described rotating shaft 1 has the containing cavity running through whole rotating shaft 1, described rotating shaft 1 is equipped with steady pin 3 in described containing cavity, one end of described moving contact 2 is rotatablely arranged on described steady pin 3, and described moving contact 2 is arranged below a lobe 4 in described steady pin 3, described lobe 4 is provided with removable pin 5, described steady pin 3 is connected to the support component for being fixed on by whole contact operating mechanism on circuit breaker base, the both sides of described support component are provided with the contact torsion spring 6 being arranged in outside described steady pin 3.
Described support component includes fixing plate 7, and the both sides of described fixing plate 7 have upwardly extended two blocks of side plates 8, and described two blocks of side plates 8 are all connected on described steady pin 3.
During installation, first moving contact 2 loaded between described two blocks of side plates 8 and connect with steady pin 3, removable pin 5 penetrates in moving contact 2, two touch springs 6 are accommodated in the both sides of two blocks of side plates 8 respectively, the two ends making two contact torsion springs 6 are all located at the top of removable pin 5, finally load in rotating shaft 1 by whole parts, after loading rotating shaft 1, one end of described contact torsion spring 6 is resisted against in described rotating shaft 1, and the other end is resisted against on described removable pin 5.
When moving contact 2 is when closing position, contact torsion spring 6 is compressed by removable pin 5, and the active force of contact torsion spring 6 acts on removable pin 5, removable pin 5 applies power and moving contact 2, owing to moving contact 2 rotates around steady pin 3, under the effect of lever principle, it is possible to produce contact pressure.
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-mentioned example; under the premise without departing from this utility model spirit and scope; this utility model also has various change and change, and these changes and change both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
