BNC to screw terminal adapter connector No name BNC-G/S — coaxial signal adapter

BNC-G/S is a BNC to screw-terminal adapter connector designed to convert BNC coaxial connections to bare-wire or screw-terminal wiring. This coaxial signal adapter allows a standard BNC male plug to interface with stranded or solid conductors by means of a compact screw terminal block. It is suitable for applications that require fast, temporary or test connections where a reliable electrical contact and straightforward wiring are needed.

Advantages

The adapter provides a simple mechanical conversion from BNC to fixed-wire terminations without the need for soldering, solderless crimping tools, or specialized connectors. Its compact design makes it easy to carry and use in confined spaces, while the screw terminal secures wires firmly for stable signal transmission. The adapter supports quick connection and disconnection of coaxial video or RF lines, which is useful for field diagnostics, temporary setups, and lab test configurations.

Suitable for

• CCTV camera connections and surveillance system testing
• Temporary installations and on-site repairs
• Laboratory and bench testing of RF or video equipment
• Connecting coaxial outputs to measurement instruments or terminal blocks

Key specifications

• Connector type: BNC male input to screw terminal output
• Contact method: Screw-clamp terminal for bare conductors
• Signal compatibility: Coaxial video and RF signals (analog and compatible formats)
• Construction: Compact inline adapter suitable for tight spaces
• Wire size: Accepts typical stranded or solid conductor sizes used in signal wiring (small gauge)

How to use

To use the adapter, insert a BNC plug into the BNC male input until it locks with the bayonet coupling. Strip a short section of insulation from the conductor to expose the bare wire, then insert the conductor into the appropriate screw terminal and tighten until secure. Ensure the central conductor is connected to the signal terminal and the shield/ground to the appropriate terminal to maintain correct signal polarity. Confirm the connection integrity before powering equipment or transmitting signals.

Usage recommendations

For reliable performance, use clean, properly stripped conductors and avoid over-tightening screws which can damage fine stranded wire. Use the adapter for temporary, testing, or diagnostic purposes; for permanent installations, consider using purpose-built connectors or soldered joints designed for long-term environmental exposure.
