CH-2 Quick Connector Cable Clamp Terminal Block

CH-2 Quick Connector Cable Clamp Terminal Block is an essential, tool-free wiring solution designed to simplify and speed up electrical connections for various low-voltage applications. This reusable two-way splice connector utilizes a reliable spring-lock mechanism, which securely clamps solid or stranded conductors without the need for screws or soldering. Consequently, installation time decreases dramatically compared to traditional terminal blocks or splicing methods. Furthermore, the connector’s transparent housing allows technicians to visually verify the correct wire insertion length, ensuring a safe and robust electrical connection every time. Installers widely use the CH-2 connector to achieve fast, safe, and aesthetically pleasing wire termination in lighting fixtures, junction boxes, and DIY electronics projects.

Key Features:

• Tool-Free Connection: Features a quick-release spring clamp mechanism, enabling users to establish secure electrical contact simply by pushing the lever down and inserting the wire.
• Two-Way Splice: Designed as a 2-pin connector, it easily splices two wires together or provides a quick connection point for input and output lines.
• Reusable Design: The spring clamp allows for repeated connections and disconnections, therefore, simplifying maintenance and modifications to existing circuits.
• High Safety Rating: The flame-retardant insulating shell provides strong protection against electric shock and short circuits.
• Wide Wire Compatibility: Accepts a range of common wire sizes (AWG 18-12 / 0.75-2.5 mm²), accommodating both solid and stranded conductors.

Technical Specifications:

• Rated Voltage (V_max): 250 V_AC / 4 kV surge

• Rated Current (I_max): 10 A
• Applicable Wire Gauge: 18 − 12 AWG (0.75 − 2.5 mm²)
• Number of Poles: 2 (Input/Output)
• Strip Length Requirement: ≈ 9 − 11 mm
• Operating Temperature: −40°C to +105°C

Mechanical Specifications:

• Contact Material: Phosphor Copper / Stainless Steel Spring
• Insulating Material: Flame Retardant PC (Polycarbonate)
• Locking Mechanism: Spring-type clamp
• Reusability: Designed for multiple cycles without loss of clamping force.

Dimensions:

• Length: ≈ 20 mm
• Width: ≈ 17 mm
• Height: ≈ 13 mm
• Weight: ≈ 2 g (Extremely compact and lightweight)

Pinout and Wiring:

• Pin 1 (Input/Line): Insert the first stripped wire (e.g., Live or Neutral) by pushing down the corresponding spring clamp lever.
• Pin 2 (Output/Load): Insert the second stripped wire (e.g., Load or continuation) by pushing down the remaining spring clamp lever.
• Wiring Method: In essence, you must ensure you fully strip the conductor (9-11 mm) and that no bare wire extends beyond the housing after insertion to maintain safety.
• Polarity: This connector does not enforce polarity; however, you must ensure that wires of the same potential (e.g., Live to Live, Neutral to Neutral) are connected together in separate blocks when extending a circuit.
