Locking ramps on both sides click into the matching receptacle housing and hold under vibration; you'll hear the latch seat before the harness leaves your hand. You need the matching Mini-Fit Jr male crimp pins to populate the 5 cavities. ## Locking Ramp — Vibration Duty Without a Secondary Lock The fastening type is a locking ramp, not a screw or bayonet. When mated, the ramp on the plug housing deflects over the ramp on the receptacle and snaps home. It holds against the kind of vibration you get on a moving vehicle or a conveyor line — enough that you don't need a secondary latch for most harness builds. The trade-off is that unmating requires pressing the ramp release, which takes two hands if the harness is stiff. For field-service swaps, plan for access to both sides of the connector.","metaTitle":"Molex Mini-Fit Jr 0039014057, 5-Pos 4.20mm Plug Housing","metaDescription":"Molex 0039014057 Mini-Fit Jr 5559 plug housing, 5 circuits, 4.20mm pitch, locking ramp, natural PA66.
