4V4 Solder-Cup High-Current Power d connector– 4 All High-Current Contacts, Pure Power Transmission, A Reliable Choice
The 4V4 solder-cup high-current dsub connector is a highly reliable connecting device in the full recessed high-current D-SUB series. Featuring a 4 all high-current contact layout with pure power transmission design, combined with a classic D-shaped shell and solder-cup termination structure, it is specifically designed for high-power equipment power transmission. With strong carrying capacity, firm wiring, rugged and durable construction, it is widely adapted to high-current connection scenarios under harsh industrial conditions.
I. Product Structural Features
The 4V4 adopts a standard D-shaped industrial connector profile with a 4 all high-current power contact configuration, mixing male and female pins, abandoning conventional signal pin design, and focusing on high-power power transmission.
The termination uses a solder-cup structure, suitable for manual soldering of cables and batch wiring harness processing, adapting to various specifications of high-power cables. The metal shielded shell is secured with locking screws, providing firm locking during mating, preventing loosening and disconnection, effectively resisting connection failures caused by equipment vibration, pulling, and bumping.
The insulator uses high-temperature resistant flame-retardant material. The contacts are thickened and enlarged in design, combined with gold/tin plating process, offering oxidation resistance, corrosion resistance, and low conductive loss, ensuring no overheating and no oxidation during long-term power-on operation.
II. Core Performance Advantages
1. 4 All High-Current Output
Thickened dedicated power contacts provide strong current carrying capacity per contact, supporting continuous and stable high-current power transmission, meeting the pure power connection needs of equipment high-power power supply, module power supply, and power source interfacing.
2. Solder-Cup Termination for Maximum Stability
The soldering process provides a tight contact surface. Compared to crimping or screw termination, it offers better resistance to pulling and vibration, suitable for high-vibration environments such as mobile equipment, vehicle-mounted equipment, and industrial machine tools, eliminating risks of false contact, arcing, and power failure.
3. Strong Anti-Interference & Protection Capability
The metal shielded shell provides excellent electromagnetic shielding effectiveness, isolating external electromagnetic interference. The structure has strong sealing adaptability and can be upgraded for dustproof, moisture-proof, and oil-resistant applications, adapting to workshop, outdoor, and damp confined installation spaces.
4. Durable, Anti-Aging, Wide-Temperature Operation
High-quality engineering plastic + high-strength metal hardware, flame retardant, high and low temperature resistant, aging resistant, wear resistant, long mating life, capable of long-term continuous operation, reducing equipment maintenance costs in the later stage.
