Create a small patch of molten solder by placing the end of the heated soldering iron against a roll of the substance, then apply the molten solder to the crocodile clip and wire connection and allow this to cool. Alternatively, there may be metal wings that can be bent into place using pliers in order to secure the wireĪpply solder. If there is no screw, you may need to crimp the wire to hold it in place, using a suitable crimp tool. Thread the now-exposed end of the wire through the hole at the back of the clip and then loop it around the fastening screw if one is available, before tightening to hold it in place. A light pinch should be sufficient to cut through the coating, allowing it to be easily peeled away Use wire strippers to remove the plastic insulation from the end of the wire. Follow the guidelines below to connect wires to a battery or similar electrical device using crocodile clips, then test the connection:įirstly, ensure that all electrical items are disconnected from power However, using clips to create an electrical connection is more complex. If you are using a crocodile clip purely as a clamp to hold two objects in place, operation is normally straightforward. They also have a multitude of additional uses, including everything from suspending models to attaching tent ropes. Meanwhile, larger crocodile clips are often used in garages and car maintenance, where they are used with battery chargers and jump leads or for welding operations, where they can also usefully absorb excess heat.Ĭrocodile clips also have some non-electrical functions – for example, attaching identification badges or entry passes to clothing, assembling models before glue or solder is applied, and for holding dentistry bibs in place. In addition, crocodile clips are also frequently used in education to demonstrate the function of batteries, bulbs or circuitry. the entrance and exit points of an electrical current). For example, this could be between two wires or between an electrical lead and the anode or cathode of a device (i.e. They are typically made from steel or copper and are also known as alligator clips, plier clips, and battery clamps.Ĭrocodile clips are principally used to create flexible, temporary or experimental electrical connections in industrial settings or laboratories. What are Crocodile Clips and What Do They Do?Ĭrocodile clips are spring-loaded attachments with serrated edges and small teeth.
