Abstract
The utility model discloses a copper-based compound tin oxide contact provided with a welded layer, which comprises alloy copper (1), and the upper part and the lower part of the alloy copper (1) are respectively compounded with silver tin oxide (2) and a welded layer (3). The copper-based compound tin oxide contact has the benefits of having performance superior to that of a powder alloy silver contact, making up the deficiency in performance of a copper-based alloy contact, and simultaneously saving noble metal, namely silver, and having simple method.
Description
Technical field
The utility model relates to a kind of circuit breaker accessory, particularly a kind of copper base band layer composite tin oxide contact.
Background technology
Powder metallurgy silver contact commonly used causes its cost height because its material will be used noble metal silver, costs an arm and a leg.
Summary of the invention
At the shortcoming of conventional contact, the utility model provides a kind of novel copper base band layer composite tin oxide contact.
To achieve these goals, the measure taked of the utility model:
A kind of copper base band layer composite tin oxide contact comprises alloyed copper, the compound siller tin oxide of upper and lower difference and the weld layer of described alloyed copper;
Described weld layer is an antimony.
The beneficial effects of the utility model: the utility model performance has surpassed the powder metallurgy silver contact, has remedied the deficiency on the performance of acid bronze alloy contact, save noble metal silver again simultaneously, and method is simple.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of copper base band layer composite tin oxide contact comprises alloyed copper 1, compound siller tin oxide 2 of the upper and lower difference of described alloyed copper 1 and weld layer 3; Described weld layer 3 is an antimony.
The beneficial effects of the utility model: the utility model performance has surpassed the powder metallurgy silver contact, has remedied the deficiency on the performance of acid bronze alloy contact, save again noble silver simultaneously, and method is simple.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
Claims (2)
1. a copper base band layer composite tin oxide contact comprises alloyed copper (1), it is characterized in that the compound siller tin oxide of upper and lower difference (2) of described alloyed copper (1) and weld layer (3).
