CH3.96 terminal connector
Backed by three core components with robust technology
the connection is more stable and reliable.
In fields such as industrial control and home appliance manufacturing, the reliability of connectors directly determines the operational safety of equipment. Guangdong Deke Electric has been deeply engaged in the connector industry for years and launched the CH3.96 terminal connector — a high-performance product where every technical parameter, from terminals to plastic housings and pin headers, is solid and fully validated. Whether for current transmission or signal conduction, it delivers impeccable performance with stable capabilities. Below is a detailed analysis based on actual test data.

CH3.96 Core Parameters Quick Overview
First Clarify the Basic Adaptation Scope
The core competitiveness of the CH3.96 model lies in "strong adaptability + high durability". With flexible specification coverage, it can easily match most conventional wiring scenarios, reducing the problems of wrong model selection and troubles caused by rework:
Specification Flexibility: 2~16 circuit configurations with an adjacent pin pitch of 3.96mm, compatible with everything from simple circuits to multi-signal transmission, covering all corresponding models from 3.96-2P to 3.96-16P.
Wide Wire Compatibility: Fully compatible with AWG24#~18# wires, eliminating the need for additional wire replacement or adapters, thus reducing procurement and assembly costs.
Accurate PCB Board Matching: Designed for wire-to-board applications, precisely compatible with 1.6mm thick PCB boards. No modification to PCB design is required, as it directly aligns with mainstream industry specifications.
Stable Environmental Durability: Operating temperature range: -25℃~85℃, adaptable to most working conditions such as northern winter workshops and southern humid warehouses, with no need for additional temperature control protection.

CH3.96 Three Core Components Breakdown
Quality Lies in the Details
CH3.96 Terminal:The "Golden Path" for Current Transmission
The terminal is the "heart" of the connection, and its electrical conductivity and mechanical strength directly determine the connection lifespan. The CH3.96 terminal adopts high-spec materials and craftsmanship, maximizing its core performance:
Solid Material Quality: Adopts phosphor bronze (C5191) as the base material with a thickness of 0.25mm, combining excellent electrical conductivity and elasticity. The surface treatment ensures smooth conduction — after a 24-hour salt spray test, no severe corrosion occurs on the metal surface, enabling long-term stability even in humid environments.
Efficient Electrical Conductivity: Rated current 5A, rated voltage 250V AC/DC, meeting the power supply needs of most low-voltage equipment. Contact resistance ≤ 0.015Ω (i.e., 15mΩ); tested to transmit stably at 10mA current with almost negligible signal loss, making it particularly suitable for precision signal transmission such as sensors.
Durable Mechanical Performance: Crimping force meets graded standards based on wire gauge — AWG24# ≥ 20N, AWG18# ≥ 50N, ensuring no loosening in vibrating environments. Single-contact insertion force ≤ 15N and extraction force ≥ 2N, providing a smooth operation feel without easy detachment. After 50 insertion-extraction cycles, the contact resistance remains ≤ 25mΩ, satisfying the long-term maintenance needs of equipment.
CH3.96 Plastic Housing:The "Solid Armor" for Safety Protection
CH3.96 Plastic Housing is not just an "outer shell" but also the core line of defense for insulation, flame retardancy, and anti-misinsertion. The CH3.96 Plastic Housing makes no compromises on safety performance:
Material Selection: Made of nylon PA66, complying with UL94V-2 flame retardant standard. It can effectively retard combustion at high temperatures, minimizing the risk of electrical fires at the source.
Insulation Performance:Insulation resistance ≥ 1000MΩ, with a withstand voltage of 1500V AC/1min. No breakdown or sparking occurs under the limit of 1mA leakage current, significantly reducing the creepage risk between adjacent terminals and ensuring the safety of personnel operation.
Structural Design: The retention force between the terminal and plastic housing ≥ 30N, preventing the terminal from loosening easily after insertion. Equipped with precision dimensional control (e.g., 2P plastic housing: A dimension 3.96mm, B dimension 8.50mm), it enables quick alignment during assembly, reducing issues such as reverse insertion or misalignment.
CH3.96 Pin Header:The "Stable Cornerstone" for Wire-to-Board Connections
CH3.96 Pin Header: The biggest concerns for wire-to-board connections are "prone to detachment during soldering and inaccurate positioning". Through detailed design, the CH3.96 Pin Header effectively addresses these pain points:
Secure Pin Retention: Pin retention force ≥ 20N, ensuring no detachment from the pin header even under force during soldering. With precise pin header dimensions (e.g., 2P pin header: A dimension 3.96mm, B dimension 7.92mm), it perfectly matches the plastic housing.
Hassle-Free Soldering: Compatible with wave soldering process, maintaining no deformation at a soldering temperature of 255±5℃ for 4±1 seconds. The terminals feature excellent solderability — when immersed in a solder bath at 245±5℃ for ≤3 seconds, the solder coverage rate exceeds 90%, quickly forming full solder pads and improving mass production efficiency.
Uncompromised Performance:When combined with terminals and plastic housings, performance indicators such as insulation resistance and withstand voltage are fully consistent. After high-temperature (105℃) and low-temperature (-25℃) cycle tests, no damage occurs and contact resistance remains stable.

CH3.96 丨Real-World Application & Multi-Field Compatibility
Consumer Electronics Field:Internal wiring connections of smart home appliances (e.g., control boards and sensors in rice cookers) and signal transmission of small instruments and meters. The 2~16 circuit configurations flexibly adapt to different functional modules.
Industrial Control Field:I/O Module Connections for Small-Scale PLCs, and Signal Transmission Between Production Line Sensors and Controllers. Its temperature resistance of -25℃~85℃ adapts to complex workshop environments.
Automotive Electronics Field:Power supply wiring connections for in-vehicle audio-visual equipment and dashcams. The anti-vibration design ensures no transient interruption and stable contact during driving.
Medical Devices Field:Internal wiring of portable monitoring instruments. The low contact resistance ensures the accurate transmission of monitoring data, and the high insulation performance complies with medical device safety standards.
