N Jacks (Female) : Types, Structure, and Uses Explained

N connectors utilize a threaded coupling mechanism that ensures a firm and stable connection. Unlike push-on or bayonet systems, this screw-on design prevents accidental disconnection and maintains consistent contact even in environments with heavy vibration or movement. The connectors securely join using 5/8-24 threads, providing highly stable signal transmission.

N connectors mate through male and female interfaces, securely joining their center contacts. These N Jacks (female) are designed to mate exclusively with N plugs (male), and they are available in various configurations, including flange mount types, to support different equipment connection needs.

The N Jack (female) features a female interface on the mating side, while the opposite end is designed for connection to a coaxial cable. Within the N connector family, multiple configurations are available to support different equipment and installation requirements.

Straight Jacks: Engineered for standard cable connections, these jacks provide secure mating and stable electrical performance for general radio frequency applications.

Flange Jacks: In addition to the main opening for the connector body, the equipment chassis is prepared with bolt or screw holes. The connector is secured using four mounting holes, which provides a robust and stable mounting solution. This configuration is commonly used in applications requiring maximum mechanical stability and grounding reliability.

Bulkhead Jacks: These jacks are secured to the equipment chassis by passing the connector body through a prepared opening and fastening it with a tightened nut from the opposite side. This design is ideal for situations where mounting space is limited or rapid assembly is necessary. Tyclon offers N Jacks (female) in bulkhead configurations that are suitable for high-frequency applications and fit coaxial cables such as RG-316, RG-174, and RG-188.

N Jacks (female) are commonly used in applications that require reliable performance, high power handling, and durability in demanding environments. Due to their secure threaded coupling and robust construction, they are especially suitable for outdoor installations and environments subject to vibration, moisture, and temperature variations.

Typical applications include:
- Mobile communication base stations and wireless infrastructure.
- Broadcast and radio frequency transmission systems.
- Test and measurement equipment.
- Industrial and outdoor communication systems.
- Radar and defense-related applications.

For equipment integration, Flange Jacks are frequently utilized. In addition to the main opening for the connector body, the equipment chassis is prepared with bolt or screw holes. The connector is secured using four mounting holes, which provides a robust and stable mounting solution. This configuration is commonly used in applications requiring maximum mechanical stability and grounding reliability.

N Jacks (female) are typically mounted on equipment panels, but types designed to be attached directly to the end of a coaxial cable also exist, often serving as cable extensions. The basic installation procedure is as follows:

1. Cable Compatibility Check
N Jacks (female) require compatible products that match the coaxial cable type to be connected. You must select a connector that matches the specific system impedance, such as 50 ohm, and suits the specific cable, such as RG-58/U, RG-8/U, or 5D-2V. Ensuring exact cable compatibility minimizes signal reflection and maximizes performance up to 10 gigahertz. For details on the attachment method of each jack, please check the materials, plating, and attachment column on the respective product page.

2. Connection of the Center Contact and the Conductor
The inner conductor (core wire) of the coaxial cable is connected to the female center contact. The connection method varies by product, but mainly includes soldering or crimping. Soldering fixes the core wire to the center terminal using solder, while crimping (compression) secures the center contact to the core wire with a specialized tool.

3. Connection of the Connector Body and the Outer Jacket
The outer shield (braid) and outer jacket of the coaxial cable must be secured to the connector body. This is crucial for ensuring the ground connection of the signal and guaranteeing the tensile strength of the cable. For N Jacks (female), this is typically achieved through crimping (fixed with a sleeve) or clamping (tightening a nut). Clamping-type connectors provide a stronger mechanical connection than crimp types, making them ideal for rigorous outdoor applications.
