Abstract
The utility model relates to an electric contactor, which is used for a switch of an electric appliance with a low voltage, such as an industrial electrical appliance, a household appliance, etc., and comprises a material layer of silver nickel 10, a layer of copper materials and a layer of weld materials. The three material layers are rolled and compounded into compound plates through heating and are punched into electric contactors of various shapes. Because a structure compounded by multilayer material layers is adopted by the utility model, a great amount of noble metal silver or silver nickel alloy can be saved by the utility model, and thereby, the price of the electric contactor is reduced, and weld is simple and convenient because a compound layer forming the electric contactor comprises a weld layer. The utility model can be widely used for the switch of the electric appliance with low voltage, such as the industrial electrical appliance, the household appliance, etc., and the utility model has the advantages that price is low, performance is good, and the utility model is a multi-layer compound electric contactor with notably economical and social benefits.
Description
The utility model is a kind of electrical contact that is used for low-voltage electrical apparatus switches such as industrial electrical equipment, household electrical appliance, belongs to the innovative technology of electrical contact.
Used electrical contact in the low-voltage electrical apparatus switches such as existing industrial electrical equipment, household electrical appliance, main this not only will expend a large amount of noble metals with silver and silver alloy manufacturing, and the electrical contact price of being produced is also more expensive, both increase the burden of manufacturer, also increased user's burden; And because these electrical contacts do not have weld layer, so the welding trouble is used inconvenience.
The purpose of this utility model is to consider the problems referred to above and a kind of MULTILAYER COMPOSITE electrical contact is provided that it not only can save a large amount of noble metal silver or silver-nickel, and its welding easily, and is easy to use.
Structural representation of the present utility model includes weld material layer (1), the copper material bed of material (2), silver-colored nickel 10 material layers (3) as shown in drawings, three material layers by rolling compound be one.
The above-mentioned copper material bed of material (2) place weld material layer (1) above, silver-colored nickel 10 material layers (3) place the copper material bed of material (2) above, three material layers are compound by hot rolling system to be one.
Describe concrete structure of the present utility model in detail below in conjunction with embodiment:
Fig. 1 is a structural representation of the present utility model;
Fig. 2-1, Fig. 2-2 is the vertical view of Fig. 1.
Embodiment:
Structural representation of the present utility model as shown in drawings, include weld material layer (1), the copper material bed of material (2), silver-colored nickel 10 material layers (3), the above-mentioned copper material bed of material (2) place weld material layer (1) above, silver nickel 10 material layers (3) place the copper material bed of material (3) above, each material layer by rolling compound be one.The thickness of the above-mentioned copper material bed of material (2), silver-colored nickel 10 material layers (3) as required can be identical, also can be different, and weld material layer (1) is thinner relatively.Different shapes such as that electrical contact can be done is circular, rectangle are shown in Fig. 2-1, Fig. 2-2.
The utility model when producing in batches, earlier with above-mentioned trilaminate material layer compound by hot rolling system be sheet material, become the electrical contact of different shape again by mould punching.
The utility model under full phase microscope, observe the tissue of material and compound interface in conjunction with situation, visible its even tissue, composite bed does not have crackle and pore, in conjunction with tight, bond strength is greater than 98N/mm
2, meeting the requirement of GB5588-85, its physical and mechanical properties and anti-electrical wear and resistance fusion welding can all reach specification requirement.
The utility model is owing to adopt the structure that is composited by the multilayer material layer, therefore, it not only can save a large amount of noble metal silver or silver-nickel, compare with similar fine silver electrical contact and silver-colored nickel 10 electrical contacts, can save silver 40～60%, thereby greatly reduce the price of electrical contact, both alleviated the burden of manufacturer, also alleviated user's burden; And owing to include weld layer in the composite bed of composition electrical contact, so its welding is simple, convenient.The utility model can be widely used in the low-voltage electrical apparatus switches such as industrial electrical equipment, household electrical appliance.The utility model is that a kind of price is low, and performance is good, all more significant a kind of MULTILAYER COMPOSITE electrical contact of economic benefit and social benefit.
