CN201829362U - Silver-cadmium oxide composite contact - Google Patents

Abstract

The utility model discloses a silver-cadmium oxide composite contact which comprises a plate-shaped alloy copper layer (1), a silver-cadmium oxide layer (2) is arranged above the alloy copper layer (1), and a welding layer (3) is arranged below the alloy copper layer (1). The silver-cadmium oxide composite contact has the beneficial effects that the performance of the silver-cadmium 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

The Agcdo composite contact

Technical field

The utility model relates to a kind of circuit breaker accessory, particularly a kind of breaker contact point.

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, and cost is very high like this, and the contact of adopting other inexpensive materials to make, quality is difficult to assurance again.

Summary of the invention

At the deficiency of conventional circuit breaker contact, the utility model provides a kind of novel Agcdo composite contact.

To achieve these goals, the measure taked of the utility model is:

The Agcdo composite contact comprises the alloyed copper layer of sheet material shape, and the alloyed copper layer is provided with the Agcdo layer, the following weld layer that is provided with of alloyed copper layer;

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 figure of the present utility model.

Embodiment

As shown in Figure 1, the Agcdo composite contact comprises the alloyed copper layer 1 of sheet material shape being compounded with Agcdo layer 2 on the alloyed copper layer 1 that the following composite welding layer of alloyed copper layer 1 constitutes layer structure for 3, three layers together, and 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 again Agcdo, make required specification, make the contact shape, again the contact is put into the vacuum oxidation furnace and be incubated 23-24 hour 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 processing 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. Agcdo composite contact comprises the alloyed copper layer (1) of sheet material shape it is characterized in that alloyed copper layer (1) is provided with Agcdo layer (2), the following weld layer (3) that is provided with of alloyed copper layer (1).

2. Agcdo composite contact according to claim 1 is characterized in that, described weld layer (3) is the antimony material.
