Abstract
The utility model discloses a silver contact structure comprising a connecting block, wherein one side of the connecting block is provided with a supporting block, the other side of the connecting block is provided with a first contact layer, and the other end of the supporting block is provided with a second contact layer. Due to the adoption of the structure in which one side face of the connecting block is coated with a silver layer and the other end of the supporting block is coated with a silver layer, power supply devices can be protected, and the production cost of the product can be greatly reduced.
Description
Technical field
The utility model relates to electronic component, particularly a kind of silver contact structure for switch.
Background technology
Electric elements are people's daily life indispensable articles for use, particularly mains switch, and mains switch plays a protective effect to circuit; so; the element that adopt the mains switch the inside is just quite important, and particularly wiring place of zero line and live wire must adopt low-melting metal to make.Existing degree silver contact can only reduce the contact and heat up, and is very little to the effect of conduction, just is easy to be burnt after several times more than the switch of employings degree silver contact uses.
The utility model content
The purpose of this utility model is at the above-mentioned defective of prior art, to provide a kind of silver contact structure.
For solving the above-mentioned deficiency of prior art, technical scheme to be solved in the utility model is: a kind of silver contact structure, comprise a contiguous block, and a side of contiguous block is provided with a piece, the opposite side of described contiguous block is provided with first contact layer, and the other end of described piece is provided with second contact layer.
As a kind of improvement of the utility model silver contact structure, described first contact layer and described second contact layer are silver-colored member.The silver member has low-melting characteristics, and when short circuit, the silver contact in the mains switch is heated and fuses automatically, and electrical equipment is played a protective role.
As a kind of improvement of the utility model silver contact structure, described contiguous block and described piece are the copper member.It is low that the copper member has price, durable, wear-resisting, is conducive to the long-term use of mains switch.
As a kind of improvement of the utility model silver contact structure, the thickness of described first contact layer and described second contact layer is selected in following scope: 0.1mm-0.5mm.The thickness that first contact layer and second contact layer are selected for use can be selected according to the size of mains switch, and resource avoids waste.
As a kind of improvement of the utility model silver contact structure, the thickness of described first contact layer and described second contact layer is 0.2mm.
Compared with prior art, the utility model has the advantages that: the utility model adopts and covers one deck silver layer in a side of contiguous block, and the other end of a piece covers one deck silver layer, can play a protective role to power supply apparatus, can reduce production cost of products greatly again.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below just with reference to the accompanying drawings the utility model is further described.
As shown in Figure 1, a kind of silver contact structure comprises a contiguous block 1, and a side of contiguous block 1 is provided with a piece 2, and the opposite side of contiguous block 1 is provided with first contact layer 3, and the other end of a piece is provided with second contact layer 4.
Wherein, first contact layer 3 and second contact layer 4 are silver-colored member.The silver member has low-melting characteristics, and when short circuit, the silver contact in the mains switch is heated and fuses automatically, and electrical equipment is played a protective role.
Contiguous block 1 and a piece 2 are the copper member.It is low that the copper member has price, durable, wear-resisting, is conducive to the long-term use of mains switch.
The thickness of first contact layer 3 and second contact layer 4 is selected in following scope: 0.1mm-0.5mm.The thickness that first contact layer 3 and second contact layer 4 are selected for use can be selected according to the size of mains switch, and resource avoids waste.
The utility model adopts the first thick contact layer 3 of 0.2mm and second contact layer 4 to be suitable for the silver contact of most mains switch, can protect power supply apparatus, can save cost again.
Claims (5)
