Stopper (plug) with TPU contact and solder connection Key benefits Protects and seals unused connector openings while maintaining reliable electrical contact where needed. TPU contact material offers flexibility and wear resistance, reducing abrasion and maintaining consistent contact under repeated use. Solder connection provides a permanent, low-resistance electrical/mechanical joint for stable long-term performance. Main features Function: Stopper/plug for closing or finishing connector interfaces and cable ends. Contact material: TPU (thermoplastic polyurethane) — flexible and durable contact surface. Connection type: Solder — intended for permanent attachment by soldering. What this solves Prevents contamination and mechanical damage to exposed connector pins or sockets. Enables secure, long-lasting connections when a removable crimp or screw termination is not suitable. Provides a flexible contact surface that helps absorb movement and wear without compromising conductivity. Compatibility and installation Designed for applications that accept a soldered stopper/plug with TPU contact material. Confirm matching connector geometry before installation. Installation requires soldering skills and appropriate tools; designed for permanent or semi-permanent assemblies rather than frequent plug/unplug cycles. Typical use scenarios Electronics assembly or repair: use as a soldered plug to finish off cable ends or close unused ports during device assembly. Custom wiring and prototyping: secure permanent connections where a compact, flexible contact surface is preferred. Shipping, storage, and maintenance: plug exposed connectors to protect contacts from dust and light mechanical wear before final installation. Why choose this product Simple, function-focused design with TPU contacts and solder termination for a secure, lasting connection. Practical solution for technicians and assemblers who need a reliable plug that is easy to solder into place. Note Product requires soldering for attachment. Verify compatibility with your connector housing or mating components prior to purchase.
