CMK422 2 Circuit Quick Connect Terminal Block for Efficient Electrical Wiring
TheJINH CMK422 quick connect terminal block is a compact two-circuit electrical connector designed for applications requiring convenient installation, reliable connection, and organized wire management.
As part of the JINH CMK42 series push-in quick connectors, CMK422 provides two independent connection circuits in one compact housing. This design allows installers to connect multiple conductors while maintaining a neat and structured wiring layout.
The connector adopts a lever-operated push-in connection system. By using the orange operating levers, users can quickly open and close each connection position without traditional screw tightening tools.
With its compact structure, transparent housing, and durable internal materials, CMK422 is suitable for residential, commercial, and industrial electrical applications.
Dual Circuit Design for Flexible Electrical Connections
CMK422 features a two-circuit connection structure.
Compared with the single circuit CMK401 model, CMK422 provides two independent connection positions in one connector, allowing two conductors or two wiring paths to be managed together.
The dual circuit design helps improve wiring organization in applications where multiple electrical connections are required.
Typical applications include:
- LED lighting systems
- Electrical fixtures
- Junction boxes
- Control equipment
- Building wiring systems
- Equipment internal connections
By combining two circuits into one compact component, CMK422 can help reduce the number of individual connection parts needed in certain wiring applications.
The compact design is especially suitable for installations where space efficiency and connection convenience are important.
Quick Connect Terminal Block with Lever Operation
CMK422 uses a lever-operated quick connection structure.
The orange operating levers allow installers to control each individual circuit easily.
During installation, users can open the lever, insert the prepared conductor, and close the lever to complete the connection.
This operating method provides a practical alternative to traditional screw terminal blocks.
Compared with screw-type connections, CMK422 helps reduce manual tightening steps and improves installation efficiency, especially in projects requiring repeated wiring operations.
The lever structure also provides convenient access during maintenance, inspection, or wire replacement.
Push-in Wire Connector for Fast Installation
The CMK422 is designed as a push-in wire connector, allowing efficient electrical connection without complicated installation procedures.
The push-in design enables faster wiring compared with conventional terminal solutions.
For electricians, installers, and equipment manufacturers, reducing installation time can improve overall project efficiency.
The connector supports both flexible and rigid conductors, providing greater application flexibility.
Whether used in lighting installations, control systems, or electrical equipment manufacturing, CMK422 provides a practical wiring solution.
Transparent Polycarbonate PC Housing Design
The housing of CMK422 is manufactured from Polycarbonate PC material.
The transparent housing allows users to visually check the conductor position after installation.
This feature helps installers confirm whether the wire has been properly inserted into the connection area.
Polycarbonate provides good mechanical strength and durability, making it suitable for electrical connector applications.
The transparent structure also gives CMK422 a clean appearance while improving installation visibility.
For electrical projects requiring accurate wiring confirmation, the transparent housing provides additional convenience.
Reliable Internal Electrical Components
CMK422 uses selected materials to ensure stable electrical performance.
The operating lever is made from Polyamide PA66, providing good mechanical strength and durability for repeated operation.
The conductive parts are manufactured from tinned copper.
Copper provides excellent electrical conductivity, while tin plating helps improve corrosion resistance and maintain long-term electrical reliability.
The contact springs use AISI 301 stainless steel.
The stainless steel spring provides consistent contact pressure, helping maintain a secure connection between the conductor and conductive parts.
The combination of PC housing, PA66 lever, tinned copper conductor, and stainless steel spring creates a reliable connection structure for different electrical applications.
Wide Compatibility with Flexible and Rigid Wires
CMK422 supports different conductor types.
Technical specifications include:
- Flexible wire: 0.08–2.5mm²
- Rigid wire: 0.2–4mm²
- Connection capacity: 0.08–4mm²
- Rated voltage: 450V AC
- Rated current: 32A
This wide wire compatibility makes CMK422 suitable for various electrical installation requirements.
Flexible conductors can be used in applications requiring easier routing, while rigid conductors are suitable for fixed wiring installations.
The recommended stripping length is:
10mm / 0.39 inch
Following the correct stripping length helps ensure reliable electrical contact.
