Core advantage |
The laminated structure reduces the skin effect, with less contact between the insulating layer and the conductor, high flexibility, and the ability to be folded and twisted |
It has strong seismic resistance, is suitable for equipment vibration and thermal expansion and contraction, and has better high-temperature resistance than laminated type |
The Core structure for insulated copper flexible connector
1.Conductive core:
High-purity oxygen-free copper braided tape (or copper foil lamination) is adopted as the core conductive component. Both ends are solidified into solid copper terminals through cold pressing or brazing processes to ensure high current transmission capacity and connection reliability.
2.Insulating protective layer：
Insulating materials are coated on the surface of the conductive core. Common processes and materials are as follows:
3.Heat shrink tube coating：
Polyolefin, fluoroplastic (PTFE, PVDF) or silicone rubber heat shrink tubes are selected. After heating, they are closely attached to the core body. The insulation layer thickness is 0.3-2.0mm, and it has the characteristics of flame retardancy, high-temperature resistance and acid and alkali corrosion resistance.
4.Dip molding process：
The core is immersed in epoxy resin or polyurethane insulating resin. After curing, a uniform insulating layer is formed, with a protection level up to IP67, making it suitable for damp and dusty environments.
5.Local insulation spraying：
Only the non-connection areas are sprayed with insulating paint, leaving the terminal parts exposed to meet the conductive connection requirements of specific scenarios.
Customization Options For insulated copper flexible connector：
The connector length, width, thickness, hole number and sizes,Cross Sectional Area,insulated materials, all can be customized as your request.
