CMK642 4 Circuit Pluggable Wire Connector for Flexible Electrical Connections
TheJINH CMK642 is a 4 circuit pluggable wire connector designed to provide a flexible and efficient solution for modern electrical connection requirements.
Different from traditional fixed terminal blocks, CMK642 combines pluggable connection capability with lever-operated wiring technology, allowing users to complete electrical connections in a more convenient way.
The connector is designed for applications where quick installation, reliable connection, and easy maintenance are important.
As part of the JINH CMK64 series, CMK642 provides four independent circuits in one compact connector structure. The product can be used as a pluggable electrical connection component while also supporting lever operation for wire installation and maintenance.
This makes CMK642 suitable for electrical installers, equipment manufacturers, automation companies, control cabinet builders, distributors, and wholesalers looking for flexible wiring solutions.
Pluggable Design for Fast Installation
One of the main advantages of CMK642 is its pluggable connector design.
The plug-in structure allows the connector components to be connected and separated conveniently during installation, equipment assembly, or maintenance.
Compared with traditional permanent wiring methods, pluggable connectors can provide greater flexibility when equipment needs to be assembled, transported, inspected, or replaced.
This design is especially useful for:
- Electrical equipment assembly
- Lighting systems
- Control cabinets
- Automation equipment
- Modular electrical installations
By using a detachable connection structure, installers can save time during installation and improve maintenance efficiency.
Lever Lock Wiring Structure
CMK642 also integrates a lever wire connection mechanism.
The orange operating lever provides a simple and practical way to secure conductors.
During installation, users can open the lever, insert the wire conductor, and close the lever to complete the connection.
Compared with traditional screw terminals, the lever structure reduces the need for repeated tightening operations.
Benefits include:
- Faster wiring process
- Easier installation
- Convenient maintenance
- Reduced installation steps
- Better wiring organization
The independent lever operation allows each connection point to be handled separately, making inspection and adjustment easier.
Compact 4 Circuit Connection Design
CMK642 provides 4 independent connection circuits within a compact housing.
The four-circuit configuration is suitable for applications where several wires need to be connected while maintaining a small installation footprint.
The compact structure helps:
- Reduce wiring space
- Improve connection organization
- Simplify installation layouts
- Support modular electrical designs
For projects requiring more circuits, the CMK64 series also includes:
- CMK643 – 6 Circuit Connector
- CMK644 – 8 Circuit Connector
Customers can select the appropriate model according to their wiring requirements.
Reliable Material Construction
Material selection plays an important role in electrical connector performance.
CMK642 uses carefully selected materials for its housing, operating components, and internal conductive structure.
Polycarbonate PC Housing
The connector shell is manufactured from Polycarbonate PC.
PC provides mechanical strength and helps protect internal connection components.
The transparent housing design allows users to observe the internal connection area, helping during installation and inspection.
Polyamide PA66 Lever
The operating lever is made from Polyamide PA66.
PA66 provides good mechanical performance for repeated operation.
The lever design allows convenient opening and closing during wiring installation and maintenance.
Tinned Copper Conductive Parts
The internal conductive components use tinned copper.
Copper provides efficient electrical conductivity, while the tin-plated surface helps improve corrosion resistance.
This material combination supports stable electrical performance during long-term operation.
AISI 301 Stainless Steel Contact Springs
The contact springs are made from AISI 301 stainless steel.
The spring structure provides stable contact pressure between the conductor and conductive parts.
This helps maintain reliable electrical connection during equipment operation.
Wide Wire Compatibility
CMK642 supports different conductor types.
Technical specifications:
- Flexible wire: 0.2–1.5mm²
- Rigid wire: 0.2–2.5mm²
- Rated voltage: 450V AC
- Rated current: 24A
- Working temperature: -40℃ to 105℃
- Strip length: 11mm / 0.43 inch
The wide wire compatibility makes CMK642 suitable for various electrical installation environments.
