Solderless waterproof LED strip connectors

These 10mm 2-wire couplers join two waterproof LED strip lights with a flexible 15cm wire between them. The pack contains 10 connectors designed for single-colour SMD5050 strips. Each connector punches through the silicone coating from the bottom to contact the PCB without stripping the waterproof layer. Installation is tool-free by opening the top, inserting the strips, and closing the latch.

For installers keeping the IP rating intact

Suits anyone linking waterproof 10mm 2-conductor strips around corners or contours while preserving the seal. Not for use with non-waterproof strips that lack a silicone coating, as the bottom-piercing contacts will not seat correctly. Also unsuitable for RGB or multi-colour strips that need more than two conductors, or for buyers who want a rigid butt joint instead of a flexible wire link.

10mm 2-conductor PCB compatibility

The connectors only fit waterproof strips built on a 10mm wide 2-conductor PCB. Strip width, conductor count and silicone coating must match this specification for the piercing contacts to make a reliable connection.

Questions about this item

Will the silicone seal on these 10mm couplers need resealing after repeated bending?

The connectors punch through the strip's silicone coating to contact the PCB directly, so the original waterproof seal remains intact and no additional resealing is required.

How much current can the 2-pin flexible wire carry before voltage drop becomes an issue on a 15cm run?

Each coupler uses a 15cm 2-wire link designed for single-colour SMD5050 strips; the short length keeps resistance low for typical low-voltage LED loads.

Do the vinyl and silicone housings stay cool when the connected strips run all day?

The connectors are passive mechanical joints with no active components, so they do not generate heat; only the LED strips themselves warm up during continuous operation.
