Abstract
The utility model relates to a die for a three-layer composite silver contact, which is characterized in that: the utility model provides a die for a three-layer composite silver contact, which can meet the market demand, produce three-layer composite silver contacts and realize the bidirectional disconnection and closing of electronic and electrical appliances.
Description
Technical Field
The utility model relates to the technical field of dies, in particular to a die for a three-layer composite silver contact.
Background
The silver contact is widely used as the intersection point of mutual separation and contact when the electronic appliance is opened and closed, because the metal conductor terminal is easy to generate instant heating and spark at the contact moment, the contact point is easy to generate oxidation and electrolysis in the multi-frequency process of use, the contact point is enlarged and thickened, or is made of high polymer metal (more than two materials of copper and silver), and the contact point made of the high polymer metal or the enlarged and thickened point made of the same material is called as the silver contact.
The existing silver contact mainly comprises a full silver contact, a composite silver contact and the like, the full silver contact is relatively expensive and is not high in cost performance, so that the composite silver contact in the current market is relatively, the composite silver contact in the market is only made of two materials, the contact surface with a silver layer and copper are mainly formed on one surface of the contact surface, the copper is riveted into a mounting hole of a conductive contact plate in the mounting process, the contact surface with the silver layer is used for being in conductive contact with another contact, only unidirectional opening and closing can be achieved, bidirectional opening and closing cannot be achieved, along with the development of the society, a plurality of electronic appliances need to be opened and closed in two directions, and the market does not have a mold capable of producing the silver contact which is opened and closed in two directions.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a die for a three-layer composite silver contact, which can meet the market demand, produce the three-layer composite silver contact and realize the bidirectional opening and closing of an electronic appliance.
The utility model provides the following technical scheme for achieving the purpose: a mould that is used for compound silver contact of three-layer which characterized in that: the die comprises a die body, wherein a die cavity with two open ends is arranged at the axial center of the die body, and an annular groove concentric with the die cavity is arranged in the die cavity.
By adopting the technical scheme, when the mould is used, the corresponding mould is selected according to the silver contacts with different diameters, the diameter of the mould cavity is slightly larger than that of the silver contacts, the concentricity of the three layers of materials is ensured in the processing process, and the deformation consistency of the three layers of materials is ensured.
Further setting the following steps: the die body is provided with a discharging through hole, and the discharging through hole penetrates through the annular groove.
By adopting the technical scheme, the discharging through holes are convenient for cleaning waste materials in the annular groove, so that the structure is simple and the design is reasonable.
Further setting the following steps: and a material guide inclined plane is arranged at one opening end of the discharging through hole.
By adopting the technical scheme, the waste materials in the discharging through hole can be conveniently led out.
Further setting the following steps: the die body is cylindrical.
By adopting the technical scheme, the production and installation are convenient.
The utility model is further described below with reference to the accompanying drawings.
