Our products Double Side Contacts 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.
The Tri Metal Contact Rivets are contacts composed of two or three materials. Generally, the head is covered with silver (silver alloy), the base is copper, and the feet are also covered with a layer of silver (silver alloy). , This process is slowly becoming popular internationally and is a good cost-saving method; the spot welding type Three Compound Contacts are also a contact composed of two or three materials. The common one is a layer of silver (silver alloy ), the middle layer is copper, and the bottom layer is iron (or iron plated with nickel or Monel alloy).
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.
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.
The new Ag/Cu/Ag Trimetal Contacts include a matrix and a composite layer. The matrix is composed of a head and a foot. The head and the foot are both cylindrical, and the diameter of the head is larger than the diameter of the foot. The composite layer includes a head composite layer and a foot composite layer, the head composite layer is composited on the upper surface of the head, and the foot composite layer is composited with the lower surface of the foot; the matrix is made of pure copper material , The composite silver layer is made of silver alloy material, and the silver alloy is composed of fine-grained silver; the beneficial effects of the utility model: the utility model relates to providing Trimetal Electrical Rivets using pure copper and silver alloy, The composite molding of pure copper and fine-grained silver materials is used, with low production cost, high material strength, high welding resistance and arc burn resistance, high electrical conductivity, and low contact resistance. Three Compound Rivets are suitable for low-voltage electrical appliances with operating currents below 10A. The Electric Double Metal Contact Rivet that can replace pure silver materials are applied to many occasions.
