It belongs to UR type wire conductors butt splice, which changed complicated traditional cable wire twist and soldering connection method.

Insert three conductors separately into 3 ports without stripping conductors insulation; Crimp or squeeze the yellow button onto the inside three conductors with a pliers (here is not included).

Gel-filled inside design promises an air-tight environment for conductors.

Good quality and exquisitely design offer corrosion-resistant function to protect the connection against air and moisture.

Applied to the conductors with inner diameter of 0.4—0.9mm
