CMK423 3 Circuit Lever Wire Connector for Flexible Electrical Wiring Solutions
TheJINH CMK423 lever wire connector is a compact electrical connection component designed to provide convenient, reliable, and efficient wiring solutions for various electrical installations.
As part of the JINH CMK42 series push-in quick connectors, CMK423 features a three-circuit structure that combines multiple connection points in one compact housing.
The connector adopts an independent lever-operated connection design. Each orange lever controls its corresponding circuit, allowing installers to complete wiring operations quickly while maintaining clear connection organization.
Compared with traditional screw terminal blocks, CMK423 provides a simpler connection method without requiring repeated screw tightening. This makes it suitable for applications where installation efficiency, wiring flexibility, and maintenance convenience are important.
With a transparent PC housing, durable electrical materials, and compatibility with flexible and rigid conductors, CMK423 is widely used in lighting systems, electrical equipment, control cabinets, and industrial wiring projects.
Three Circuit Design for Organized Wire Connections
CMK423 features a three circuit connection structure.
Compared with the two-circuit CMK422 model, CMK423 provides one additional connection position, allowing more conductors to be arranged within a single connector.
The three-circuit design helps improve wiring organization and reduces the need for multiple separate connection components.
Typical applications include:
- LED lighting connections
- Electrical junction boxes
- Control panel wiring
- Equipment internal wiring
- Automation systems
- Building electrical installations
By integrating three independent circuits into one compact connector, CMK423 provides a practical solution for projects requiring multiple wire connections while maintaining a neat installation layout.
Lever Wire Connector for Easy Operation
The key feature of CMK423 is its lever-operated connection mechanism.
The orange operating levers allow users to open and close each connection point independently.
During installation, the lever can be lifted, the conductor inserted, and the lever closed to secure the wire connection.
This design provides several advantages:
- Faster wiring operation
- Easier conductor replacement
- Convenient electrical inspection
- Reduced installation steps
For electricians and equipment manufacturers, the lever structure simplifies wiring work and improves operational efficiency.
The independent lever design also allows individual circuits to be maintained without affecting other connected wires.
Reliable Alternative to Traditional Screw Terminals
Traditional screw terminal blocks require manual tightening for each connection point.
CMK423 uses a lever connection structure instead, helping reduce the need for additional tools during installation.
The lever mechanism provides a straightforward method for connecting conductors while maintaining stable electrical contact.
For projects with many wiring points, this design can help improve installation efficiency.
CMK423 is especially suitable for applications where frequent wiring adjustments or maintenance may be required.
Transparent Polycarbonate PC Housing
CMK423 uses a transparent Polycarbonate PC housing.
The transparent design allows users to visually check the internal conductor position after installation.
This helps installers confirm whether the wire has been properly inserted.
Polycarbonate material provides good mechanical strength and durability, making it suitable for electrical connector applications.
The transparent housing design combines practical inspection capability with a modern appearance.
Durable Electrical Materials
CMK423 is manufactured with carefully selected materials to ensure reliable electrical performance.
Polyamide PA66 Lever
The operating levers are made from Polyamide PA66.
PA66 provides suitable mechanical strength and durability for repeated operation.
Tinned Copper Conductive Parts
The conductive components are made from tinned copper.
Copper provides excellent electrical conductivity, while tin plating helps improve corrosion resistance.
AISI 301 Stainless Steel Contact Spring
The contact springs use AISI 301 stainless steel.
The stainless steel spring maintains consistent contact pressure, helping ensure stable electrical connection performance.
The combination of PC housing, PA66 levers, tinned copper conductors, and stainless steel springs provides a reliable structure for long-term electrical applications.
Wide Wire Compatibility
CMK423 supports both flexible and rigid conductors.
Technical specifications:
- 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℃
This wide conductor compatibility allows CMK423 to be used in various electrical installation environments.
The recommended stripping length is:
10mm / 0.39 inch
Correct wire preparation helps ensure stable contact performance.
