Cap Head Silver Contacts
Products Description
Cap Head Silver Contacts are high-precision composite contacts specifically designed for power meters and magnetic latching relays. Unlike traditional solid silver contacts or three-component structures, this product features a double-eyelid or stepped cap-shaped design, focusing on the special shape of the silver layer at the head and the thickness control of the middle working surface. This structure significantly reduces overall manufacturing costs while maintaining necessary conductivity.
Material Properties and Advantages
Competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
Material Pretreatment
Degrease and clean the silver and copper alloys to ensure no oxide layer on the surface for Point Contact for DC Electronic Latching Relay.
01
Stamping
Use high-precision dies to stamp out the cap-shaped head (double eyelid or stepped shape) and the middle working surface. The stamping pressure must be controlled during this process to prevent material cracking.
02
Composite Welding
Precision weld the silver alloy head to the copper alloy base. Use spot welding or laser welding to ensure a strong metal-to-metal bond between the two materials for Three Phase Latching Relay.
03
Hardness Tempering
Heat treat the finished Miniature Magnetic Latching Relay to adjust the surface hardness (contact layer HV≥120) to prevent dents from forming during high-voltage arcing.
04
Quality Inspection
Perform microstructure analysis for Cap Silver Contacts for Latching Relay and resistivity measurement to ensure the silver layer thickness on the head is sufficient and uniform.
05
Frequently Asked Questions
Is this a solid silver contact?
+
-
No. This contact is typically a composite contact structure, consisting of a silver alloy contact layer and a copper base layer.
Why is a stepped structure design used?
+
-
The stepped structure reduces the amount of silver used while ensuring sufficient silver layer thickness in the central contact area.
In which devices is Point Contact for DC Electronic Latching Relay mainly used?
+
-
Mainly used in power meters, magnetic latching relays, and related electrical control equipment.
Can the Three Phase Latching Relay structure be customized according to drawings?
+
-
Yes. Contact size, shape, and materials can be customized according to equipment requirement
