Our products Trimetal Electrical Rivets Features:
1-Trimetal Contacts can save costs 30%-65% than Solid Silver Contacts;
2-Very reliable mechanical strength for both sides composite materials,like Solid Contacts;
3-The silver layers on the head and foot are accurately distributed to ensure the contacts gap after riveted with stamped terminal;
4-Surface anti-oxidation protective film, can resist oxidation for a long time;
5-High dimensional accuracy ±0.01-0.02mm;
6-Strong corrosion resistance;
7-Good electrical conductivity.
Tri-metal Rivet Contacts are normally used as double sides contacts,mainly used in Relays, Micro Switches,Button Switches and Contactors,etc.Trimetal Material have Ag/Cu/Ag,AgNi/Cu/AgNi,AgCdO/Cu/AgCdO,AgZnO/Cu/AgZnO, AgSnO2/Cu/AgSnO2,AgSnO2In2O3/Cu/AgSnO2In2O3 and so on.Available with us is a range of Contact Rivets. Trimetal Electrical Contacts are manufactured with wire by cold heading process. This helps in making the shank soft for easy riveting and the head is work-hardened. The length of the shank can be varied but the diameter of Trimetal Contact Rivets is needed to be in right proportion to the size of head. This enables us to avoid wrinkles during cold forging operation. These economically priced Composite Contact Rivets can be manufactured in various dimensions. The limit to the dimension of Multi-layer Silver Contacts is due to the requisite ratio between head diameter to head thickness.
In order to overcome the shortcomings in the prior art, the purpose of the present invention is to provide Tri Metal Contacts and a manufacturing device for the triple composite contact. The triple composite contact has a simple structure, good strength, hardness, welding resistance and arc burn resistance. The device for manufacturing the Trimetal Rivet Contacts can directly cut the raw material and can be directly cold-headed, which is convenient to use and low in cost. High efficiency, effectively ensuring the strength and hardness of the contacts, and a wide range of applications.
The Trimetal Rivet-type Contacts include a pure copper matrix, a silver compound composite layer and a connecting composite layer. The pure copper matrix is composed of a truncated cone-shaped head and a cylindrical foot, and the cone-shaped head and the cylindrical foot are integrally arranged, A first groove is provided on the side of the head facing away from the foot, and a silver compound composite layer is provided on the first groove. The silver compound composite layer is embedded with the first groove, and the foot the side facing away from the head is provided with a second groove, the second groove is provided with a connecting composite layer, and the connecting composite layer is embedded with the second groove. The Trimetal Rivets of the utility model has good electrical conductivity, and the silver compound composite layer on the head is not easily deformed and will not fall off from the pure copper substrate.
