EJ-1121 USB AF WITH JOINT

Solderless USB Solutions: USB A Female to 5-Pin Screw Terminal Joint 

Simplify your custom wiring and DIY electronic projects with our USB A Female to 5-Pin Screw Terminal Adapter. This versatile connector allows you to terminate USB cables or create custom power and data interfaces without the need for a soldering iron.

The adapter features a standard USB Type-A Female port on one end and a secure 5-way screw terminal block on the other. Designed for high-speed data transmission and reliable power delivery, the screw joints provide a firm, vibration-resistant connection for a wide variety of industrial, laboratory, and hobbyist applications.

Key Performance Features:

• Solder-Free Connection: Quickly attach stripped wires directly to the screw terminals for immediate use.

• 5-Pin Configuration: Includes pins for VCC (Power), Data-, Data+, Ground, and Shield for full USB compatibility.

• Precision Top View: Clearly defined terminal slots ensure easy wire insertion and alignment.

• Rugged Enclosure: Durable black thermoplastic housing protects the internal connection from physical strain.

• Compact Joint Design: Streamlined form factor is ideal for tight spaces in control panels or enclosure builds.

Technical Specs 

• Connector A: USB Type-A Female (AF).

• Connector B: 5-Pin Screw Terminal Block (Plug-in type).

• Joint Type: Screw terminal joint.

• Pinout Labels: Typically labeled for standard USB wiring (V+, D-, D+, GND, S).

• Housing: High-grade PVC and metal shield.

Typical Applications

• Cable Repair: Fixing broken USB ports on devices or repairing cut cables without soldering.

• Prototyping: Connecting breadboards or microcontroller projects to USB power sources or data links.

• Industrial Controls: Integrating USB peripherals into machines where standard molded cables cannot be easily routed.

• Custom Charging Stations: Building bespoke power distribution units for USB-powered electronics.

Top 3 Customer Questions & Concerns ‍

1. Does this support data transfer or just power?

   • It supports both. The 5-pin layout includes data lines (D+ and D-) as well as the shield for full high-speed USB data functionality.

2.  How secure are the screw terminals?

   • The screw-down mechanism is designed to bite firmly into the wire, providing a more vibration-resistant connection than standard push-fit joints.

3. Can I reuse this adapter for multiple projects?

   • Yes. Unlike soldered connectors, you can simply unscrew the terminals to swap out wires for new configurations anytime.
