Crocodile Clips

Crocodile clips, also known as alligator clips, are spring-loaded clips made from metal. Crocodile clips are typically serrated and have small teeth. They are commonly used in electrical and electronic testing and prototyping to temporarily connect wires and components without soldering, allowing for quick and easy adjustments and measurements.

Types of Crocodile Clips

Insulated Crocodile Clips

Insulated alligator clips feature a protective covering over the metal jaws, enhancing safety by preventing accidental short circuits and improving grip on wires.

Non-Insulated Crocodile Clips

Non-insulated crocodile clips lack protective covering, offering direct metal-to-metal contact. They are commonly used in applications where insulation is not necessary or would impede conductivity.

Heavy-Duty Crocodile Clips

Heavy-duty crocodile clips are designed with stronger springs and more robust jaws, capable of securely gripping thicker wires and components, ideal for industrial and high-current applications.

Micro Crocodile Clips

Micro crocodile clips are smaller in size, and designed for delicate electronic work or applications where space is limited, maintaining precision while ensuring reliable connections.

Materials Used in Crocodile Clips

Crocodile clips can be constructed from a variety of metals, but the most common are steel (stainless, nickel plated or gold plated) and copper.

Stainless steel

Stainless steel is incredibly hard-wearing and resistant to corrosion, making it a popular choice for crocodile clips. However, stainless steel can be a difficult material to solder, which you may need to take into consideration when choosing the right crocodile clip for your application.

Nickel-plated steel

Nickel-plated steel is also used for making crocodile clips as this material is suited to a wide range of industries in NZ and (like stainless steel) provides you with excellent corrosion resistance.

Gold-plated steel

Gold-plated steel crocodile clips are typically more expensive than other steel counterparts but are ideal for applications that require a low level of resistance and a high level of conductivity. Gold plating wears fairly easily, so you should only use this type of clip in situations where a large number of cycles are not required.

Copper

Copper crocodile clips are suited to applications that require excellent electrical conduction.

Applications of Crocodile Clips

Crocodile clips and alligator clips are most commonly used for making temporary electrical connections. These cable clamps can be used to connect two wires or to connect one lead directly to a device. Here are some of its useful applications:

• Electrical testing and measurements: Crocodile clips are used in electrical testing and measurements to temporarily connect wires, components, and testing equipment. Their spring-loaded jaws ensure a secure grip, allowing for reliable conductivity without soldering. In laboratories and workshops, they facilitate the testing of circuits, voltage measurements, and continuity checks. Their ease of use and versatility make them essential tools for engineers and electricians.
• Educational demonstrations: In educational environments, crocodile clips play a crucial role in hands-on learning activities focused on electrical principles. They are used by teachers and students to illustrate basic concepts such as circuitry, conductivity, and component connections. By connecting batteries, bulbs, and switches with crocodile clips, educators can create interactive demonstrations that enhance understanding and engagement in science and technology classes.
• Automotive industry: Large-sized crocodile clips are also used in the automotive industry for diagnostic and repair purposes. They can also be referred to as plier clips, plier-style clips or battery clamps. Plier clips can be used for jumper cables, battery chargers and welding applications. They are constructed from materials with low electrical resistance, such as solid copper and are insulated. Mechanics and technicians use them to create temporary connections to test electrical components, sensors, and circuits within vehicles.
• Hobbyist projects: In hobbyist circles, crocodile clips are prized for their versatility in DIY electronics projects and modelling activities. Hobbyists often use them to temporarily connect components during prototyping stages for quick adjustments and experimentation. Whether assembling electrical circuits, soldering components, or constructing miniature models, crocodile clips provide a flexible solution for holding parts together securely.
