CMK643 6 Circuit Lever Wire Connector for Efficient Electrical Connections
TheJINH CMK643 is a 6 circuit lever wire connector designed to provide a practical and flexible solution for electrical wiring applications that require multiple connection points in a compact structure.
As part of the JINH CMK64 series, CMK643 combines pluggable connection capability with lever-operated wiring technology, providing installers with a convenient way to connect, disconnect, and maintain electrical circuits.
Compared with traditional terminal blocks, CMK643 offers a more flexible connection method by integrating multiple circuits into one compact connector. The six-circuit design allows several conductors to be arranged together, helping improve wiring organization while reducing installation space.
The connector is suitable for electrical contractors, equipment manufacturers, automation companies, control cabinet builders, and distributors who require reliable and efficient wiring solutions.
Six Circuit Design for Organized Multi-Wire Connections
The main feature of CMK643 is its 6 circuit connection structure.
Modern electrical systems often require multiple wires to be connected within limited installation space. Using several separate terminal blocks may increase installation complexity and make wiring management more difficult.
CMK643 integrates six independent connection circuits into one connector body.
This design helps:
- Organize multiple wires in one location
- Reduce the number of separate connection components
- Improve wiring appearance
- Save installation space
- Simplify future maintenance
For projects requiring different circuit quantities, JINH also provides:
- CMK642 – 4 Circuit Pluggable Wire Connector
- CMK644 – 8 Circuit Electrical Connector
Customers can select suitable models according to the number of wires and connection points required.
Lever Wire Connection for Faster Installation
CMK643 features a practical lever-operated wiring structure.
The orange lever design allows users to complete wire connections without traditional screw tightening operations.
During installation, the user can open the lever, insert the conductor, and close the lever to secure the connection.
This design helps simplify wiring procedures and provides several advantages:
- Faster installation process
- Reduced wiring steps
- Easy conductor adjustment
- Convenient inspection and maintenance
- Suitable for repeated wiring operations
The independent lever operation allows each circuit to be controlled separately, making troubleshooting and wire replacement easier.
Pluggable Connection Structure for Flexible Applications
In addition to lever wiring, CMK643 supports a pluggable electrical connection design.
The detachable structure provides flexibility during equipment assembly, transportation, installation, and servicing.
For manufacturers of electrical equipment and automation systems, pluggable connectors can help improve production efficiency by making module installation and replacement more convenient.
Typical applications include:
- Modular electrical equipment
- Control cabinets
- Lighting systems
- Automation machines
- Industrial electrical assemblies
Durable Material Selection for Reliable Performance
Material quality is important for electrical connector reliability.
CMK643 uses carefully selected materials for the housing, operating mechanism, conductive components, and internal spring structure.
Polycarbonate PC Housing
The connector shell is manufactured from Polycarbonate PC.
PC material provides good mechanical strength and helps protect internal electrical components.
The housing structure is designed to maintain a compact size while supporting six independent connection circuits.
Polyamide PA66 Lever
The operating levers are made from Polyamide PA66.
PA66 provides suitable mechanical properties for repeated opening and closing operations.
The lever structure allows installers to quickly operate each connection point during installation and maintenance.
Tinned Copper Conductive Parts
CMK643 uses tinned copper conductive components.
Copper provides good electrical conductivity, while tin plating helps improve oxidation resistance.
The conductive parts work together with the contact springs to maintain stable electrical performance.
AISI 301 Stainless Steel Contact Springs
The internal contact springs use AISI 301 stainless steel.
The spring mechanism provides continuous contact pressure between the conductor and conductive components.
This helps maintain reliable electrical contact during long-term operation.
Wide Wire Compatibility
CMK643 supports both flexible and rigid conductors.
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 conductor compatibility allows CMK643 to meet different electrical installation requirements.
