Products Description
Silver Contact and Stamping is a moving reed assembly solution specifically designed for the T90 general-purpose relay structure. Its core structure consists of beryllium copper precision stamped parts, armature structural parts, and highly reliable silver contact riveting assemblies. This assembly performs critical functions such as current conduction, contact closure, and rapid rebound during relay operation, requiring extremely high material stability, elastic recovery capability, and contact reliability.
Core Product Nature and Characteristics
Continuous Die Stamping
The pre-treated beryllium copper strip is fed into a high-precision continuous die stamping machine. Precise stamping parameters are set to achieve a dimensional accuracy of ±0.01mm. An intelligent feeding system automatically corrects material strip deviations of ±0.01mm, continuously completing the stamping of the moving spring. The stamping process is monitored in real time, and defective Electrical In-Die Riveted Connections with cracks or deformities are rejected.
Beryllium Copper Aging Heat Treatment
The stamped beryllium copper moving spring is sent to a professional heat treatment workshop. A "solution + aging heat treatment" process is used, controlling the heat treatment temperature and time to ensure that the deformation recovery rate of the beryllium copper moving spring is ≥98%, and that parameters such as tensile strength and hardness meet standards for In-Die Rivet Electrical Contacts.
Pre-treatment of silver contacts and armature
The silver contacts are polished to ensure that the contact resistance is ≤80μΩ and that there are no scratches or oxidation; the armature is treated to remove rust and prevent rust, improve wear resistance and magnetic permeability, and ensure compatibility for Riveted Electrical Connection Components with beryllium copper moving springs.
Detailed Presentation and Design Advantages
Bimetallic Composite Advantages
Beryllium copper provides extremely high elasticity and strength, while silver contacts offer excellent conductivity and low resistance for In-Mold Riveting Electrical Contacts.
Ultimate Precision
Dimensional tolerances of ±0.01mm and alignment accuracy of 0.02mm enable these Riveted Electrical Connection Components to maintain stable contact during high-speed operation.
Multifunctionality
In-Die Rivet Electrical Contacts are suitable for both relay moving springs in low-voltage circuit breakers and armatures in automotive relays.
Frequently Asked Questions
What is the thinnest BeCu strip we can process?
+
-
We recommend a minimum strip thickness of 0.05mm, but even thinner materials can be processed using special molds in special cases.
Can Electrical In-Die Riveted Connections withstand high-frequency opening and closing?
+
-
Yes. Especially with C17200 beryllium copper, the deformation recovery rate is extremely high, making it suitable for high-frequency applications.
Can you provide different models of silver contacts?
+
-
We support various silver alloy models such as AgSnO₂ and AgNi. You can choose according to your wear resistance or conductivity requirements.
Can you produce according to the samples?
+
-
Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.
How long can I get a quotation?
+
-
After you send us product drawings (including material), we can give you the quotation within 1 day.
