3M Scotchlok Color-Coded Standard Female Disconnect Terminal attaches to the mating part with a tongue that slips over the male tab. This terminal has a butted-seam barrel which is covered by a funnel-designed, rigid-molded, polyvinyl chloride sleeve. The polyvinyl chloride sleeve serves to guide the wire into position while providing electrical contacts and mechanical stress relief at the point of insulation. The vinyl-sleeve insulation is abrasion-resistant and flared to ensure easy crimping.
