Products Description

This AC Relay Core Assembly is a purpose-built magnetic circuit component for industrial control relays used in new energy and power electronics systems. Its design comprises an axially oriented pure iron substrate with an integrally riveted copper terminal. As the central functional element of the AC electromagnetic relay, it critically governs engagement stability, mechanical vibration suppression, and service life under both power-frequency and harmonic-distorted conditions. The assembly complies with the demanding specifications of industrial-grade AC relays, offers form-fit-function interchangeability with equivalent imported magnetic cores, and supports sustained high-duty-cycle operation under severe grid fluctuations and heavy electrical loading.
Product Structure Disassembly
Main Magnetic Core Matrix
DT4C pure iron cylindrical matrix, CNC-grooved, serves as the main body of the soft magnetic circuit, conducting alternating electromagnetic flux.
Riveted Copper Terminal Assembly
Stamped copper conductive terminals are fixed to one end of the AC Rod using a precision riveting process, forming a conductive connection node.
Precision Grooving Structure
Grooves are evenly distributed along the axial direction for magnetic circuit adjustment and assembly positioning. This is a key structural feature that distinguishes the AC Relay Magnetic Core from DC cores.
Overall Assembly
The magnetic circuit body and conductive terminal structure are integrated into a single unit, forming the AC Relay Core and Copper Ring assembly, which is directly used for the AC relay body assembly.

Manufacturing Advantages
Full-Process Closed-Loop Capability
From material heat treatment and cold heading to riveting assembly, all processes are completed in our own factory. This means that the quality traceability of Core AC can be directly traced back to the raw material batch and individual processing equipment, rather than relying on the quality inspection reports of external suppliers.
Specialized production ensures consistency
For the riveting process of the Soft Magnetic AC Relay Core, specialized riveting equipment and positioning fixtures are used to ensure consistency in the copper short-circuit ring pressing depth and riveting force, thereby eliminating random deviations caused by manual operation.
Capacity and delivery
Relying on a mature multi-station cold heading and CNC lathe group, it can simultaneously meet the needs of small-batch Pure Iron Core for AC Relay trial production and large-volume continuous supply. Standard product delivery time is 7-15 days, and urgent orders can be coordinated for rapid production changeover response.

Packaging and transportation
| Inner packaging | AC Core Riveted with Copper Terminal is individually packaged on anti-static blister trays. The quantity on each tray is set according to the component size. The trays are sealed with PE anti-static film to prevent bumps and oxidation during transportation. |
| Outer packaging | Blister trays are placed in triple-layer corrugated cardboard boxes, and the boxes are filled with cushioning bubble wrap. The outer packaging of the box bears a Grooved Core for AC Relay product label, indicating the part number, batch number, quantity, and RoHS/REACH compliance markings. |
| Shipping methods | Export orders for AC Rods can be shipped by sea, air, or express (DHL/FedEx/UPS). Export customs clearance and certificates of origin can be processed according to customer requirements. |
