Abstract
The utility model relates to a fixed contact assembly of a contactor, comprising a copper contact plate (1), a silver contact (2) and an iron arcing ring (3). The fixed contact assembly is characterized in that the silver contact (2) is welded on the upper part of the copper contact plate (1), the iron arcing ring (3) is embedded in the upper part of the copper contact plate (1) and fixed on the lower part of the copper contact plate (1), and the outer edge of the upper part of the copper contact plate (1) is identical with the shape of the crotch shape of the iron arcing ring (3). The utility model has high electricity and abrasion resisting performance, and achieves the purpose of saving silver.
Description
Technical field
The utility model relates to a kind of fixed contact system of contactor, particularly finger tentaculum fixed contact assembly.
Background technology
Because contactor in its course of work, often will connect under rated voltage and disjunction rated current or bigger electric current, and this process is accompanied by the generation of electric arc often and burns.Produce the intensity of electric arc and directly related with the structure of contact system to the degree of wear of contact, and the shape of the used material of contact system, structural member and between relation be main influencing factor.Contact system is made of moving contact and fixed contact assembly, and the bridge-type moving contact that adopts is more satisfactory at present, but there is weak point in the structure of fixed contact assembly, as the material that elongates electric arc is not set, has strengthened silver contact.Innovation and creation to contactor are a lot, and few to the novel designs of contact system.For China of silver-colored inadequate resource, joint silver highly significant.
The utility model content
The purpose of this utility model is to provide a kind of fixed contact assembly of contactor, the fixed contact height of anti-the electric abrasioning performance, and it is remarkable that joint copper saves silver-colored effect.
For achieving the above object, the solution that the utility model is taked is: a kind of fixed contact assembly of contactor comprises copper contact plate, silver contact, irony arc leading angle.Weld silver contact on copper contact plate top, the irony arc leading angle embeds the top of copper contact plate and is fixed on the lower part of copper contact plate, and the outer on copper contact plate top and the fork shape of irony arc leading angle match.
In the utility model, the fixed contact outer is that the outer and the irony arc leading angle fork shape on copper contact plate top matches, the tracks of electric arc arc root is almost in the same plane like this, can make arc root on the fixed contact can be successfully under the effect of arc current self-excitation magnetic field and irony arc leading angle from the edge transitions of fixed contact to the irony arc leading angle, irony arc leading angle external part is long, elongate electric arc, helped extinguishing fast, improved the anti-electric abrasioning performance of contact.Thereby maximally utilise the irony arc leading angle around the fixed contact, reached the purpose of economizing on silver.

Among the figure: 1, copper contact plate; 2, silver contact; 3, irony arc leading angle
Embodiment:
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Present embodiment is realized so as shown in Figure 1: a kind of fixed contact assembly of contactor comprises copper contact plate (1), silver contact (2), irony arc leading angle (3).On copper contact plate (1) top, weld silver contact (2), irony arc leading angle (3) embeds the top of copper contact plate (1) and is fixed on the lower part of copper contact plate (1), and the outer on copper contact plate (1) top and the fork shape of irony arc leading angle (3) match.
Claims (1)
1. the fixed contact assembly of a contactor, comprise copper contact plate (1), silver contact (2), irony arc leading angle (3), it is characterized in that: on copper contact plate (1) top, weld silver contact (2), irony arc leading angle (3) embeds the top of copper contact plate (1) and is fixed on the lower part of copper contact plate (1), and the outer on copper contact plate (1) top and the fork shape of iron arcing born (3) match.
