Products Description
Electrical contacts with cone angles are a type of high-precision, irregularly shaped special contact in the field of electrical connections. They typically employ a composite or integral contact design, and their unique cone angle shape makes them excellent at withstanding high voltage and suppressing arcing. Due to their high manufacturing difficulty, minimal material waste, and superior performance, they are commonly used in high-end electrical appliances, industrial control systems, and high-voltage applications, belonging to the category of low-to-medium production volume but high-value precision components.
Production Process and Flow
Die Design
The die for Special Size Silver Contacts typically employs multi-stage composite stamping. The key is controlling the "cone angle" and the "verification groove depth" to ensure that each stamping achieves the expected angular deviation (usually within ±0.02mm).
01
Stamping Forming
A CNC stamping machine is used to press the Bullet Type Solid Copper Contacts raw material. For integral contacts, all complex shapes need to be completed in a single stamping, while verification contacts may require two or more stampings to form the groove.
02
Surface Treatment
After Shaped Silver Alloy Contacts are formed, degreasing, rust removal, and activation treatments are performed. Subsequently, depending on the material, silver or gold electroplating is applied to form a dense coating.
03
Quality Inspection
Due to the extremely high angular precision of cone-shaped contacts, the quality inspection process typically uses a coordinate measuring machine (CMM) to measure the micro-geometric dimensions to ensure that the angular error is within the specified range.
04
Value of Structural Engineering
Improved Contact Stability
Allotype Solid Copper Contact Rivet structures generate concentrated contact pressure during contact, thus reducing the risk of contact instability.
Reduced Contact Resistance Fluctuations
Stable contact pressure for Shaped Silver Alloy Contacts reduces resistance variations, improving the reliability of electrical systems.
Optimized Mechanical Actions
In structures requiring sliding or switching, Bullet Type Solid Copper Contacts enable smoother contact actions.
Frequently Asked Questions
Are special-size silver contacts difficult to manufacture?
+
-
Yes, due to their special geometry (such as the composite structure), the mold design and stamping process require extremely high precision. This is why such products are usually custom-made and expensive.
Why choose composite contacts instead of ordinary flat contacts?
+
-
The main advantage of composite contacts is their arc-extinguishing characteristics. When an arc is generated, it can quickly form a low-voltage zone, attracting the arc to the internal groove, thus protecting the contact surface from burning.
Does the angle of the Bullet Type Solid Copper Contacts significantly affect performance?
+
-
Extremely significant. The size of the cone angle directly determines the direction and speed of arc release. The angle is typically designed between 30° and 75°; angles that are too small or too large will affect the arc-extinguishing efficiency.
What current applications are suitable for this Shaped Silver Alloy Contacts?
+
-
Depending on the material and size, it can be used in industrial switches that transmit low current signals from 10A to 500A or even higher currents.
