The JVT110/JVT187/JVT250 series of quick-connect terminal connectors have become the preferred connection solution in the fields of industrial and consumer electronics with precise specification design, reliable performance and wide adaptability. The following is a detailed analysis from three aspects: product core advantages, key application fields and typical successful cases. 
First, the core advantage of the product: the coexistence of common guarantee and series characteristics
JVT110/JVT187/JVT250 series quick connection terminals are based on "male width" (corresponding to 2.8mm, 4.75mm, 6.35mm respectively), which not only shares the core technical advantages of Qiaoye, but also forms differentiated characteristics for different current and space requirements, fully covering the scene requirements from micro signal transmission to medium power supply.
(1) A full range of common advantages
1. High reliable connection to reduce the risk of failure: The series of products are all made of forced locking structure, which can produce a stable contact retention force of about 30N after the female end is inserted, which greatly reduces the probability of terminal shedding in vibration environment. The touchpoint substrate is made of high-conductivity brass or phosphor bronze, and it is matched with multi-layer electroplating processes such as tin, silver, and nickel to ensure low contact resistance (fluctuation 3mΩ), and improve corrosion resistance and wear resistance. It can achieve stable transmission under standard working conditions of -40 ° C to 105 ° C. High-temperature models can withstand extreme environments of 250 ° C.
2. Efficient assembly and reduced comprehensive cost: With low insertion force design, the female end of the JVT110 series is the model with the lowest insertion force in congeneric products. With F-type crimping, male terminal locking and other standardized crimping methods, it can be adapted to semi-automatic or fully automatic crimping equipment, significantly improving assembly efficiency - after an enterprise introduced the automated production line of this series of terminals, the daily production capacity of a single production line increased from 5,000 sets to 8,000 sets, and the yield was synchronized from 98.1% to 99.3%. At the same time, the pre-insulated model can realize "insulation + connection" in one step, reducing process losses.
3. Comprehensive compliance certification, suitable for the global market: The whole series has passed the certification of UL and other international authoritative organizations, the insulating material meets the UL 94 V-0/V-2 flame retardant grade and glowing wire test requirements, and some models meet the European Union environmental protection standards, helping customers quickly pass the regional market access audit.
4. Flexible adaptation, simplified design selection: Support 18-22AWG wide range wire diameter, provide straight, left flag, right flag and other multi-directional structures, can match PCB board mounting, wire crimping and other installation methods, no need to redevelop connection solutions for different scenarios, shorten customer Product Research & Development cycle, a full range of products support customization to meet your needs.

Case 1: Durability upgrade of Bosch electric impact drill
In the research and development of a new generation of professional electric impact drills, Bosch faced the problem of poor contact of traditional terminals in high-frequency vibration and dust environments, and chose 250 series quick-connect terminals to replace the original solution. The forced locking structure of the terminal can withstand severe vibration during impact drill operation, and the multi-layer electroplated touchpoint can effectively resist dust erosion. After 1000 hours of continuous load test, the failure rate of poor contact has been reduced from the original 2.1% to 0.1%.

The product repair rate decreased by 68% year-on-year, and the user satisfaction in the professional decoration market increased to 96%.
Case 2: Production line efficiency and cost optimization of Dongcheng electric wrench
Dongcheng, a leading domestic power tool enterprise, introduced 187 series quick-connect terminals and supporting automatic crimping equipment in the production line upgrade of the mainstream electric wrench. The low insertion force design of the terminal and the standardized crimping method shorten the assembly time of a single device from 45 seconds to 22 seconds, and the daily production capacity of the production line is increased from 3,000 units to 5,500 units. Compared with the traditional wiring method, the comprehensive cost of terminal procurement and assembly of a single product is reduced by 18 yuan, and the annual cost is reduced by more than 21.60 million yuan based on the annual production capacity of 1.20 million units. In addition, the UL certification of the terminal helped the wrench enter the North American market smoothly, and the export volume exceeded 80,000 units in the first year.
Case 3: Production line efficiency optimization in industrial manufacturing enterprises
When matching wiring harnesses for an industrial equipment customer, an automated crimping production line with 250 series terminals is introduced. Relying on the low insertion force design of the terminals and standardized interfaces, the production line realizes the automation of the whole process of "wire feeding-crimping-testing".
