From 0,3 to 6 mm2 thermo-fusible connector

The second major component of the electrical wire connection is sealing consisting of two coloured rings. Depending on the wire section, four sizes of heat-fusible sleeves are proposed by ACLP :

• 2 joints white for section 0.3 hot fuse sleeves up to 0.8 mm2,
• 2 red seals for hot fuse sleeves of section 0.8 up to 2 mm2,
• 2 blue seals for hot fuse sleeves of section 2 up to 4 mm2,
• 2 yellow seals for hot fuse sleeves from section 4 up to 6 mm2,

At the same time as the sleeve heat shrinkable is heated and retracted, both joints soften and adhere to the wire. This ensures that the electrical connection remains clean, dry and functional even under difficult conditions. Thermo-fusible connectors are thus widely used in outdoor applications, such as garden lighting, electrical fence systems, and many others.

At the heart of the thermo-fusible connectors is the tin ring, responsible for electrical continuity. Since the tin ring melts at 232 °C and the sleeve heat shrinkable retract from 120°C, first melt the tin with a mini-hot air gun, then retract the tubing with a hot air gun with deflector.

The advantage of this welding is that it is robust. Unlike other connecting techniques, such as screw terminals, hot-fuse connectors are more physically durable. Tin-based welding also guarantees a resistance-free electrical connection, which is essential for optimal electrical performance. The self-welding electric wire connection is ideal for multi-brain conductors.

A handyman may use a sleeve self-welding thermo-fusible to repair or modify the wiring of its electric bike. For example, to repair a cut battery cable, it unwounds the wires, inserts them into the sleeve heat shrinkable and heat. The inner tin ring melts and welds the threads, while the sleeve heat shrinkable tighten around the electrical wire connection. This results in a robust connection and Waterproof, resistant to the vibrations of the bike. As noted in the technical documentation, this type of connector is "very convenient for DIYers" and widely used in the electric-assisted bicycle sector. In summary, the particular user benefits from a fast splicing without soldering iron and lasting against external elements.

A residential electrician may use these connectors for installations requiring reliability and sealing, such as wiring from external lamps, safety systems or charging terminals. Rather than installing dominoes or screw pods, it can welded wires by simple heating. The bond obtained is resistant to shocks and temperature variations, avoiding further release. Moreover, the operation is very fast (the hot air gun sufficient), which accelerates the commissioning. Finally, the connector is protected against corrosion : on sleeve heat shrinkable and adhesive joints block moisture, ensuring a durable connection over time, even in case of rain or frost.

Several applications are possible for electrical wire connection : It can be found in the area of electric bicycles, high-end sound or railway, but many others. Their advantages include: :

• Reliability : no risk of loosening with vibrations, shocks or temperature fluctuations.
• Easy installation : fast and efficient installation, even in confined spaces.
• Environmental protection : with the sleeve heat shrinkable and the seal ring, it protects the connections of the external elements.

The electrical wire connection is essential for quiet and durable electrical connections. Its clever design with sleeve heat shrinkable, two coloured seals and tin ring for welding electrical wires, makes it adaptable to multiple applications. Whether in your car, on a construction site or in a plane in flight, the wire connection is there to keep the current.

ACLP distributes a wide range of wire connectors including self-welding connectors Waterproofs and sleeves to crimp.
