Abstract
The utility model relates to the field of electronic component, in particular a relay, and is an improved structure of the metal contact of a relay. The upper surface of the metal contact body with low conductivity is coated by a metal layer having high conductivity, so is the bottom of the contact body. Preferably, the metal contact body with low conductivity is a metallic copper contact. Preferably, the metal layer having high conductivity is a metallic sliver layer, or a metallic gold layer. By adopting the above technical scheme and with a composite metal contact structure, precious metal such as gold and silver is substantially saved, thereby cutting the cost of producing relay components without affecting the electric property thereof and largely increasing the profit of such product.
Description
Technical field
The utility model relates to the electronic devices and components field, relates in particular to relay, is the improvement structure to the relay hard contact.
Background technology
Relay is a kind of electronic control device; it has control system (claim not only input circuit) and Be Controlled system (but also claiming output loop); usually be applied in the automatic control circuit; it is actually a kind of " automatic switch " that removes to control big electric current with less current; so in circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit; hard contact is the critical component of relay (electronic switch), contacting and disconnect the on-off action of finishing circuit by moving hard contact and quiet hard contact.
Because relay is widely used in multiple field, some special occasions requires very high to the conducting contact resistance of relay.Because the resistivity of argent or metallic gold is little, performance is preferable, and this occasion generally adopts argent or metallic gold as the contact, yet these metals (gold or silver etc.) are precious metals, thereby makes the production cost of relay higher relatively.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of modified model hard contact, reduces the consumption of precious metal such as gold, silver greatly, and guarantees electric property.
The utility model adopts following technical scheme:
Hard contact of the present utility model, wherein, described upper surface than low conductivity hard contact body coats the high electrical conductivity metal level, and the bottom surface of described contact bodies also coats the high electrical conductivity metal.
Preferably, described is the metallic copper contact than low conductivity hard contact body.
Preferably, described high electrical conductivity metal level is a metallic silver layer.
Perhaps, described high electrical conductivity metal level is the metallic gold layer.
The utility model adopts as above technical scheme, by compound hard contact structure, saved the precious metal material of high conductivities such as gold, silver greatly, thereby under the prerequisite that does not influence its electric property, reduce the relay element production cost, improved the profit of this product greatly.
Description of drawings
Fig. 1 is the structural representation of existing hard contact.
Fig. 2 is the structural representation of hard contact of the present utility model.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult shown in Figure 1ly, the hard contact body 1 in the existing relay is to adopt the precious metal integrative-structure of high conductivity such as gold, silver to make.Therefore, the consumption to the precious metal of high conductivities such as gold, silver is bigger.
Consulting shown in Figure 2 is hard contact of the present utility model.Wherein, described upper surface 11 than low conductivity hard contact body 1 coats high electrical conductivity metal level 2, and the bottom surface 12 of described contact bodies 1 also coats high electrical conductivity metal level 2.
Preferably, described is the metallic copper contact than low conductivity hard contact body 1.
Preferably, described high electrical conductivity metal level 2 is metallic silver layer.Perhaps, described high electrical conductivity metal level 2 is metallic gold layers.
This shows that the upper surface 11 of the contact bodies 1 of hard contact of the present utility model and bottom surface 12 adopt high conductivity metal levels such as valuable argent or metallic gold 2 to coat, electric property is unaffected.Lower-costly make but its hard contact body 1 adopts, save production cost greatly than low conductivity metal (as copper etc.).
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection range of the present utility model.
