Abstract
The utility model discloses a silver-nickle oxide composite contact which has a three-layer structure sequentially consisting of a silver-nickle oxide layer (2), a plate-shaped alloy copper (1) and a welding layer (3). The silver-nickle oxide composite contact has the beneficial effects that the performance of the silver-nickle oxide composite contact is superior than that of the alloy silver contact, so that the defect of copper base alloy contact in performance is made up, precious metal silver is saved, and the processing method is simple.
Description
Technical field
The utility model relates to a kind of circuit breaker accessory, the low breaker contact point of particularly a kind of cost.
Background technology
Along with the swift and violent rise of silver-colored valency, the cost of low-voltage electrical apparatus improves greatly, and the contact that is used for circuit breaker all is all to adopt silver-colored material to make, cost height like this, and the contact of adopting other inexpensive materials to make, and quality does not reach the requirement that needs are said in the contact.
Summary of the invention
At the deficiency of the contact of conventional circuit breaker, it is a kind of with low cost that the utility model provides, performance good silver-colored nickel oxide composite contact.
To achieve these goals, the scheme taked of the utility model is:
Composite contact is divided into the alloyed copper of silver-colored nickel oxide layer, sheet material shape and the three-decker of weld layer successively.
Described weld layer is the antimony material.
The beneficial effects of the utility model: the utility model performance has surpassed the alloy silver contact, has remedied the deficiency on the performance of acid bronze alloy contact, save noble metal silver again simultaneously, and processing method is simple.
Description of drawings
Fig. 1, layer structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, composite contact is divided into the alloyed copper 1 of silver-colored nickel oxide layer 2, sheet material shape and the three-layer composite structure of weld layer 3 successively.Described weld layer 3 is the antimony material.Weld layer on the copper face of composite board is made required sheet material with rolling mill then, compound more silver-colored nickel oxide, make required specification, make the contact shape, again the contact is put into the vacuum oxidation furnace and be incubated 24 hours with 520 ℃ with stamping machine, vacuum cooled is to room temperature again, and last clean is finished.
The beneficial effects of the utility model: the utility model performance has surpassed the alloy 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. silver-colored nickel oxide composite contact is characterized in that, composite contact is divided into the alloyed copper (1) of silver-colored nickel oxide layer (2), sheet material shape and the three-decker of weld layer (3) successively.
