CMK634 4 Circuit Quick Wire Connector for Lighting and Electrical Connections
TheJINH CMK634 quick wire connector is a four-circuit electrical connection component developed for wiring applications that require a compact structure, convenient operation, and reliable electrical contact. As part of the JINH CMK63 series, CMK634 provides four independent connection positions in one compact housing, making it a practical choice for organizing multiple conductors within a limited installation area.
The connector is designed around a lever-operated connection structure. Instead of relying on traditional screw tightening, installers can operate the orange levers directly when connecting or releasing wires. This straightforward design can make repetitive wiring work more convenient and can also simplify access when a connection needs to be inspected or adjusted.
With four circuits in one connector, CMK634 is particularly suitable for lighting systems, junction boxes, control equipment, electrical panels, and equipment wiring where several conductors need to be arranged in an organized way.
Four-Circuit Design for Organized Electrical Connections
CMK634 provides 4 independent circuits, allowing multiple wire connections to be arranged within one connector.
The product measures approximately 28.1 × 19.2 × 10.3 mm. Its compact rectangular structure helps reduce the space required around the connection point while providing four connection positions.
This makes CMK634 useful in applications where several wires need to be connected but installation space is not unlimited.
For example, lighting equipment, junction boxes, control panels, and electrical equipment often contain multiple connection points within a relatively small enclosure. Using a multi-circuit connector can help keep the wiring more organized and reduce the need for several separate connection components.
The four-circuit configuration also gives distributors, installers, and equipment manufacturers another option within the CMK63 series when two or three circuits are not sufficient for a particular wiring task.
Quick Lever Operation for Easier Wiring
The orange operating levers are one of the most recognizable features of the CMK634.
During installation, the appropriate lever can be opened before inserting the prepared conductor. Once the wire is correctly positioned, the lever can be returned to its working position.
This lever-operated structure provides a simple alternative to traditional screw-type connections. It can reduce the number of manual tightening steps during installation and is especially useful for projects involving repeated electrical connections.
The same operating mechanism can also be useful during maintenance. When a wire needs to be checked, repositioned, or removed, the corresponding lever can be operated without requiring repeated screw adjustment.
For electricians and installers, this can make wiring work more straightforward and help maintain a cleaner connection layout.
Transparent Polycarbonate Housing
The CMK634 housing is manufactured from transparent polycarbonate, providing a protective enclosure for the internal connection components while allowing the connection area to remain visible.
The transparent design can help installers visually check the wire position during installation. This is particularly useful when several connectors are installed inside the same junction box or electrical enclosure.
The operating levers are made from Polyamide POM, providing a practical material solution for repeated manual operation.
The internal conductive components use tinned copper, which offers good electrical conductivity and helps protect the conductive surface against oxidation under normal conditions.
The contact springs are made from AISI 301 stainless steel. The spring provides the mechanical contact force required to maintain the connection with the conductor.
The combination of polycarbonate, Polyamide POM, tinned copper, and stainless steel provides a balanced material structure for everyday electrical connection applications.
Flexible and Rigid Wire Compatibility
CMK634 is designed to accommodate both flexible and rigid conductors.
The specified wire ranges are:
- Flexible wire:0.2–2.5mm²
- Rigid wire:0.2–4mm²
This range gives the connector flexibility for different wiring projects, from lighting installations to equipment wiring.
The main electrical specifications include:
- Number of circuits:4
- Flexible wire range:0.2–2.5mm²
- Rigid wire range:0.2–4mm²
- Rated voltage:450V
- Rated current:32A
- Housing material: Transparent polycarbonate
- Lever material: Polyamide POM
- Conductive parts: Tinned copper
- Contact springs: AISI 301 stainless steel
- Working temperature: -40°C to 105°C
- Stripping length: 11mm / 0.43 inch
- Product size: 28.1 × 19.2 × 10.3 mm
For proper installation, wires should be stripped according to the recommended 11mm stripping length and inserted correctly into the connection position.
A Practical Solution for Lighting Wiring
CMK634 is particularly suitable for electrical lighting applications where multiple conductors need to be connected within a relatively small space.
Lighting systems may require several connection points for power supply, fixtures, switches, and other electrical components. A four-circuit connector can help organize these connections without using multiple individual terminal components.
The compact structure of CMK634 makes it suitable for applications such as:
- LED lighting systems
- Commercial lighting
- Residential lighting
- Junction boxes
- Electrical distribution connections
- Building wiring
- Control panels
- Electrical cabinets
- Equipment wiring
- Automation equipment
- Household appliances
The transparent housing can also make the connection area easier to observe during installation and inspection.
Designed for Efficient Electrical Installation
Traditional screw terminal blocks remain widely used in electrical installations, but they generally require manual screw tightening for each connection.
CMK634 uses a lever-operated connection structure instead. This allows installers to perform the basic connection operation through the lever mechanism rather than repeatedly tightening screws.
For larger wiring projects, reducing individual installation steps can help improve workflow efficiency.
The lever design also provides convenient access during maintenance. If a circuit needs to be modified or a wire needs to be removed, the connection can be opened through the operating lever.
This makes CMK634 a useful option for applications where quick operation, organized wiring, and convenient maintenance are important.
JINH CMK63 Series Quick Wire Connectors
CMK634 is part of the JINH CMK63 series quick wire connectors, which includes four different circuit configurations:
