FME Connectors For Flexible Cable Industry knowledge

FME connectors for flexible cable are miniature, snap-in RF coaxial connectors designed for quick installation on thin, flexible coaxial cable. The FME interface uses a push-fit engagement instead of a threaded coupling, allowing the male and female halves to be joined or separated by hand pressure alone.

The connector body holds a spring-loaded center contact inside a smooth outer shell. When mated, the outer shell of the plug seats over the jack and the center pin makes contact through friction retention rather than a locking groove. This construction keeps the connector diameter close to the cable diameter, which is why FME connectors for flexible cable are used where routing space is limited and repeated hand-mating is required.

Core Performance Parameters

The connector operates at a 50 Ω characteristic impedance and supports frequencies from DC up to 3 GHz, which covers most mobile radio, cellular, and GPS signal bands.

Typical electrical and mechanical specifications
Parameter Typical Value
Impedance 50 Ω
Frequency Range DC – 3 GHz
VSWR ≤ 1.3
Coupling Type Push-fit, non-threaded
Mating Cycles ≥ 100

Typical Applications

The compact profile and tool-free mating of FME connectors for flexible cable make them common in equipment where cabling is routed through tight spaces and connections are made or changed frequently.

  • Vehicle-mounted two-way radios and mobile antennas
  • Cellular signal boosters and in-vehicle repeaters
  • GPS and GNSS receiver antenna feeds
  • CB radio and marine radio antenna cable assemblies

Comparison with Other Coaxial Interfaces on Flexible Cable

Compared with threaded subminiature interfaces, the push-fit design allows faster mating without a wrench or torque control, but retention force is lower, so the connector is better suited to fixed or low-vibration cable runs rather than field environments with constant flexing.

Comparison of coupling type, frequency range and retention across flexible-cable coaxial interfaces
Interface Type Coupling Frequency Range Retention
Push-fit, non-threaded Hand press-fit DC–3 GHz Low to moderate
Threaded subminiature Screw thread DC–18 GHz and above High
Snap-on subminiature Push and click DC–6 GHz Moderate

Installation and Maintenance

  1. Align the plug and jack straight, then press together until fully seated.
  2. Disconnect by pulling straight back on the connector shell, never on the cable itself.
  3. Support the cable near the connector with a clamp or tie where vibration is present.
  4. Inspect the center pin periodically for bending or oxidation.
  5. Replace the connector if mating force feels loose or VSWR readings drift out of specification.

Frequently Asked Questions

What cable sizes are FME connectors for flexible cable used with?

They are sized for thin, flexible coaxial cable typically used in mobile radio and antenna feed applications, rather than larger semi-rigid or low-loss trunk cable.

Can the connector be used outdoors?

Standard versions are intended for protected or indoor-facing installation; boot or sealed variants should be selected for direct outdoor exposure.

Why does the connection loosen over time?

Since retention relies on friction fit rather than a lock, repeated flexing or vibration can gradually reduce contact pressure, which is why strain relief support is recommended.

Manufacturing Background

Yangzhou Jingcheng Electronics Co., Ltd. produces FME connectors along with cable assemblies for flexible coaxial cable under ISO9001 quality management, following MIL, IEC, and GB reference standards across more than 30 RF coaxial connector series for communications, automotive, and mobile equipment applications.
