CMK401 Single Circuit Push-in Wire Connector for Fast Electrical Connections
TheJINH CMK401 push-in wire connector is a compact electrical connection component designed for applications requiring fast installation, reliable performance, and convenient wiring operation.
As the single circuit model of the JINH CMK42 series push-in quick connectors, CMK401 provides a simple and efficient solution for connecting electrical conductors in residential, commercial, and industrial applications.
Unlike traditional screw terminal blocks that require manual tightening, CMK401 uses a lever-operated quick connection structure. The orange operating lever allows installers to easily control the connection position, helping reduce installation steps and improve wiring efficiency.
With its compact structure, transparent housing, and reliable internal components, CMK401 is suitable for applications where space-saving design and easy maintenance are important.
Compact Single Circuit Design for Individual Wire Connections
CMK401 features a single circuit connection design.
Compared with multi-circuit models in the CMK42 series, CMK401 is designed for individual conductor connection requirements.
The compact structure makes it suitable for electrical installations where each connection point needs to remain independent and organized.
The single circuit configuration allows installers to connect wires separately according to different wiring layouts.
This design is commonly used in:
- LED lighting connections
- Electrical equipment wiring
- Junction box applications
- Control system wiring
- Building electrical installations
- Internal equipment connections
The compact size also helps save installation space, especially in electrical boxes and equipment enclosures where available space is limited.
Push-in Quick Connection Design
CMK401 adopts a push-in quick connection structure.
The orange lever provides a convenient operating method for wire installation and maintenance.
During installation, the lever can be opened, and the prepared conductor can be inserted into the connection position.
After the wire is correctly positioned, closing the lever completes the electrical connection.
Compared with conventional screw terminal blocks, the push-in design helps reduce repeated screw tightening operations.
For electricians, installers, and equipment manufacturers, this structure can improve wiring efficiency during production and installation.
The lever design also allows easier access when electrical inspection or wire replacement is required.
Transparent PC Housing for Easy Inspection
The CMK401 connector housing is made from Polycarbonate PC material.
The transparent housing design allows users to visually check the internal conductor position after installation.
This feature can help installers confirm whether the wire has been correctly inserted into the connector.
Polycarbonate provides good mechanical strength and durability, making it suitable for electrical connection components.
The transparent structure combined with the compact design makes CMK401 practical for applications where installation accuracy and visual confirmation are important.
Reliable Electrical Materials
CMK401 uses carefully selected materials for stable electrical performance.
The operating lever is made from Polyamide PA66, providing durability and suitable mechanical strength for repeated operation.
The conductive components are manufactured from tinned copper.
Copper provides excellent electrical conductivity, while tin plating helps improve corrosion resistance and maintain stable electrical contact.
The contact spring uses AISI 301 stainless steel.
The stainless steel spring provides consistent contact pressure, helping maintain reliable connections during long-term operation.
The combination of PC housing, PA66 lever, tinned copper conductor, and stainless steel spring creates a durable structure suitable for different electrical environments.
Wide Wire Compatibility
CMK401 supports both flexible and rigid conductors.
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
- Working temperature: -40℃ to 105℃
The wide wire compatibility allows CMK401 to be used in various electrical projects.
Whether used with flexible wires for equipment wiring or rigid wires for fixed installations, the connector provides a practical connection solution.
The recommended stripping length is:
10mm / 0.39 inch
Proper wire preparation helps ensure stable electrical contact and reliable performance.
