概述

The Delphi Harsh Environment Series (HES) Connection Systems include circular connectors, terminals, and a rectangular 50 and 60 way header. The 24 shell size industry standard connector includes six terminal configurations (47, 31, 29, 23, 21, and 19). Delphi's circular connection systems are available with straight and right angle conduit wire dress covers on both receptacle and plug assemblies.

The HES Connection Systems provide higher current capability, improved sealing, higher terminal retention and a significant cost advantage compared to standard pin-and-sleeve systems. Delphi HES Connection Systems are also compatible with existing systems in the commercial and agricultural vehicle markets.

Benefits

• Terminals
• High current performance is realized through the selection of high conductive materials
• Robust design with a stainless steel sleeve that provides stability and protection to contact interface area
• Overlapping wing design provides exceptional strain relief and larger outside diameter cable range capability
• Crimp stability over the terminal life with the use of tin in the crimp area
• Wide range of cable sizes accommodated with Delphi's crimp design
• Interchangeability with industry standard terminal products

• HES Circular Connectors
• Sealing performance exceeds expectations with recessed 3-rib design that will maintain sealing properties even if a tight wire dress is applied, providing better sealing capability up to 30% compared to existing designs
• Superior contact (terminal) retention performance virtually eliminates terminal unseats with a specialized finger design that results in better retention up to 40% when compared to existing designs
• Interchangeability with industry standard circular products
• Ergonomic design for ease of assembly and to maintain quality: 
  
• Arrows help simplify pre-engagement of locking collar for simplified mating 
  
• Visual lock engagement window
• Color coded seals to distinguish between various cable diameters as well as terminal gender
• Low (Less than 4 Nm) torque engage
• Robust construction to withstand SAE J-2030 Heavy-Duty Electrical Connector Performance Standard
• Sonic welded seal retainer
• Wave spring design to maintain face seal compression
  

• Header System
• Virtually eliminates unseats with Delphi’s two stage terminal retainer design
• High vibration design passes 29 Grms vibration specification
• Chemical resistant  header face seals with the use of flourosilicone
• Built-in probing window protect the female terminal during the build process
• Over-torque bolt design protects the header when too much torque is applied
• True pin position is one of the tightest in the industry at 0.225 mm, ensuring easy mounting to a circuit board
• Interchangeability with industry standard products 

Typical Applications

Delphi Harsh Environment Series products are suited for the following industries: 

• Agriculture
• Commercial vehicle
• Construction
• Marine
• Other harsh environment applications

The HES circular design is ideally suited for making connections in a vehicle sheet metal firewall pass-through locations. Because of the rugged connection system design, they are well suited for engine compartments. HES headers are an ideal choice for high density device I/Os that are mounted directly to the engine.
