Its JVT110/JVT187/JVT250 series quick-connect terminal connectors have become the preferred connection solution in industries such as industrial manufacturing and consumer electronics, thanks to their precise specification design, reliable performance, and wide adaptability. Below is a detailed analysis from three aspects: core product advantages, key application fields, and typical successful cases.
I. Core Product Advantages: Coexisting Common Guarantees and Series-Specific Features
The JVT110/JVT187/JVT250 series quick-connect terminals are mainly distinguished by "male terminal width" (corresponding to 2.8mm, 4.75mm, and 6.35mm respectively). They not only share Qiaoye's core technological advantages but also form differentiated features for different current and space requirements, fully covering application scenarios from micro-signal transmission to medium-power supply.
(I) Common Advantages of the Entire Series
- High-Reliability Connection to Reduce Failure Risks: All products in the series adopt a forced locking structure. After mating with the female terminal, a stable contact retention force of approximately 30N is generated, significantly reducing the probability of terminal detachment under vibration. The contact base material is high-conductivity brass or phosphor bronze, combined with multi-layer electroplating processes such as tin, silver, and nickel. This not only ensures low contact resistance (fluctuation ≤ 3mΩ) but also enhances corrosion and wear resistance, enabling stable transmission under standard operating conditions of -40℃ to 105℃. High-temperature models can withstand extreme environments of up to 250℃.
- Efficient Assembly to Lower Comprehensive Costs: Adopting a low insertion force design, the JVT110 series female terminals have the lowest insertion force among similar products. Combined with standardized crimping methods such as F-type crimping and male terminal locking, they are compatible with semi-automatic or fully automatic crimping equipment, significantly improving assembly efficiency. After an enterprise introduced an automated production line with this series of terminals, the daily output of a single production line increased from 5,000 sets to 8,000 sets, and the yield rate simultaneously rose from 98.1% to 99.3%. Meanwhile, pre-insulated models achieve "insulation + connection" in one step, reducing process losses.
- Comprehensive Compliance Certifications for Global Market Adaptation: The entire series has passed certifications from international authoritative institutions such as UL. The insulation material meets UL 94 V-0/V-2 flame retardancy standards and glow wire test requirements, and some models comply with EU environmental protection standards, helping customers quickly pass regional market access audits.
- Flexible Adaptability to Simplify Design and Selection: Supporting a wide wire gauge range of 18-22AWG, it offers multi-directional structures such as straight type, left flag type, and right flag type, which can match various installation methods including PCB board mounting and wire crimping. There is no need to redevelop connection solutions for different scenarios, shortening the customer's product R&D cycle. All series products support customization to meet your needs.
