This plug-in fuse power connection wire is a non-destructive power supply accessory designed specifically for the installation of car circuits. It can lead out an independent power supply circuit from the vehicle fuse box without damaging the original car wiring harness, providing stable and safe power supply for new car electrical appliances. It is a core supporting wire that balances convenience and safety in automotive electronic modification and car equipment installation scenarios, and widely adapts to the circuit upgrade needs of various passenger and commercial vehicles.

The product adopts an integrated dual circuit structure design, with standard plug-in connectors and fuse sockets integrated into the main body. It can be directly inserted into the original car fuse slot to complete power supply without cutting or breaking wires. It is installed without damage to the integrity of the original car circuit and does not affect the warranty of the original car circuit. The operation threshold is low, which is suitable for professional modification stores for batch construction and can also meet the DIY needs of car owners to install equipment on their own. The plug-in connector is divided into two independent circuits: one circuit receives the original protection function of the vehicle fuse, ensuring the normal operation of the vehicle's original circuit; The other route provides an independent power supply channel for the newly added equipment, and the two circuits do not interfere with each other, structurally avoiding the impact of installing equipment on the original vehicle circuit. The main body comes with an independent fuse slot, which can be used to install corresponding specifications of car plug-in fuses as needed, providing exclusive overload and short circuit protection for newly added equipment. In case of abnormal current or short circuit faults in external equipment, the fuse will melt and cut off the circuit in a timely manner, without affecting the original car circuit system throughout the process, fully ensuring the safety of vehicle electrical use.

In terms of material and process, the conductive plug is made of high conductivity copper alloy substrate by precision stamping, and the surface is treated with tin plating and anti-oxidation. It has excellent conductivity, low contact resistance, stable temperature rise under long-term power on conditions, and is not easy to oxidize and connect. It can adapt to continuous vibration and temperature difference changes in the cabin during vehicle driving, and always maintain reliable electrical contact performance. The insulation shell is made of high temperature resistant and flame-retardant engineering plastic integrated injection molding, with high insulation strength, impact resistance, and high and low temperature resistance. It is suitable for the complex use environment of the car cabin and interior, and can effectively isolate live parts, eliminate safety hazards such as short circuits and grounding. The lead wire adopts automotive grade specialized low-voltage wires, with multiple strands of oxygen free copper stranded conductors inside, stable current carrying capacity, and low line loss; The outer insulation layer has wear resistance, aging resistance, and temperature resistance, and can withstand daily bending and environmental aging inside the car; The connection between the wire and the joint is reinforced and sealed with heat shrink tubing, which can resist pulling and bending, effectively buffer the stress caused by long-term vibration of the vehicle, prevent the wire core from loosening and breaking, and extend the service life of the product.

This power connection cable has a compact and small structure, occupying little space after insertion, and can adapt to the internal layout of most car models' fuse boxes. After installation, it does not affect the normal closure of the fuse box cover. The product is compatible with common specifications of automotive plug-in fuses, and can flexibly select fuses with corresponding amperage according to the power of external devices. It can also adapt to different power requirements of automotive electrical equipment such as driving recorders, car navigation, reverse radar, interior ambient lights, car Chargers, and audio modification. It is a widely used, safe, and reliable basic supporting component in automotive circuit modification and equipment installation.
