Small crocodile clip connector No name KRO0390.1 — spring-loaded electrical test clip, single contact

Small crocodile clip connector No name KRO0390.1 is a compact spring-loaded electrical test clip designed for creating temporary single-point connections. The clip features metallic jaws that ensure mechanical grip and reliable electrical contact while an insulated handle reduces the risk of accidental short circuits. Its small form factor makes it convenient for prototyping, testing circuits, connecting battery leads and working with low-voltage signal lines where a temporary, easily removable connection is needed.

Advantages

The spring-loaded mechanism provides consistent clamping force for stable contact during measurements or repairs. Metallic jaws deliver good conductivity and a secure hold on component leads, wires or battery terminals. The insulated handle improves user safety by limiting exposure to conductive surfaces. The compact size allows use in tight spaces and on densely populated circuit boards without obstructing nearby components.

Suitable for

• Prototyping and breadboard work
• Temporary connections for circuit testing and troubleshooting
• Attaching to battery terminals and small power leads
• Low-voltage signal measurements and sensor connections

Key specifications

• Connection type: single contact spring-loaded clip
• Contact material: metallic jaws for electrical conductivity
• Handle: insulated for reduced risk of shorting
• Size: compact small form factor suitable for tight spaces
• Use voltage: intended for low-voltage applications and signal-level work

How to use

Open the clip by pressing the insulated handle to expose the jaws, position the jaws over the wire, terminal or component lead, and release the handle to secure the connection. Ensure the jaws make direct contact with bare metal for best conductivity and avoid clamping over insulation. Remove the clip by pressing the handle and pulling it away from the contact point. During use, avoid applying excessive force to fragile components and inspect the clip periodically for wear or corrosion.

Usage recommendations

Use this small crocodile clip for low-voltage and signal-level tasks only; avoid mains or high-current applications. For prolonged tests, verify contact integrity and replace the clip if jaws show corrosion or reduced spring tension. When working on powered circuits, isolate power when attaching or removing the clip where practical to reduce risk of short circuits.
