Product Introduction
The Custom Brass Sheet Metal Electronic Contact Ring is a precision-formed conductive component used in electrical connector assemblies and compact electronic hardware. Its cylindrical slotted structure is designed to provide stable contact, controlled flexibility, and reliable fitting inside connector housings, terminal cavities, or custom electronic assemblies.
The product shown features a thin-wall metal ring with evenly spaced vertical slots. This structure allows the contact area to maintain elasticity while supporting electrical conductivity and mechanical positioning. Brass or copper alloy materials are commonly selected for this type of component because they offer good conductivity, formability, and surface treatment compatibility.
Shenzhen Fuwanglong Hardware provides drawing-based customization for electronic contact rings, connector spring contacts, conductive sleeves, terminal inserts, and other precision sheet Metal Contact Parts. Dimensions, material thickness, plating finish, slot shape, opening width, and packaging method can be adjusted according to the customer’s application.

Main Functions
Electrical Contact and Conductive Connection
The brass contact ring is designed to support stable electrical connection inside connector systems. Its conductive metal surface helps transfer current or signal between mating parts, making it suitable for compact electronic and electrical assemblies.
Elastic Contact Support
The vertical slot structure provides controlled flexibility around the ring body. This allows the component to maintain contact pressure during insertion, assembly, or repeated connection, depending on the final design requirement.
Compact Connector Installation
The cylindrical form is suitable for use in limited internal spaces. It can be installed inside plastic connector housings, terminal cavities, sensor modules, or precision electronic hardware where space-saving contact design is required.
Mechanical Positioning Inside Assemblies
Besides conductivity, the part can also provide positioning and retention support. The formed ring body helps keep the contact area aligned during connector assembly and improves fit stability within the designed cavity.
Surface Protection and Conductivity Enhancement
Different plating options can be selected according to the application. Gold plating is suitable for stable signal contact, nickel plating improves surface protection, and tin plating can be used for cost-sensitive electrical connection parts.
OEM Drawing-Based Production
The product can be customized from customer drawings or samples. Slot width, ring diameter, height, material thickness, open seam design, plating type, and packaging can all be adjusted for specific connector or device projects.
