CMK422-8 10 Circuit Electrical Connector for Multi-Wire Applications

TheJINH CMK422-8 is a 10 circuit electrical connector developed for wiring applications that require several conductors to be connected within a compact and organized space.

As part of the JINH CMK42- series, CMK422-8 provides 10 connection circuits in one connector body. This configuration is designed for projects where six or eight connection points may not be enough and a higher circuit capacity is required.

Instead of using multiple individual connectors for separate wires, the ten-circuit structure allows several related connections to be arranged together. This can help installers maintain a cleaner wiring layout and make circuit identification and maintenance more convenient.

CMK422-8 combines a Polycarbonate PC housing with PA66 operating levers, tinned copper conductive components, and AISI 301 stainless steel contact springs. The combination is designed to provide a practical connection solution for electrical installers, equipment manufacturers, control panel builders, distributors, and wholesalers.

10 Circuit Design for High-Capacity Wire Management

The main feature of CMK422-8 is its 10 circuit configuration.

Many electrical systems contain several independent conductors. When individual connectors are used for each connection group, the number of components can increase and the wiring arrangement may become more complicated.

CMK422-8 brings ten connection circuits together in one compact product.

This design can help installers:

• Manage multiple conductors in one location
• Reduce the number of separate connection components
• Keep wiring layouts more organized
• Make better use of available installation space
• Simplify circuit identification
• Make future maintenance more convenient

The ten-circuit configuration makes CMK422-8 particularly suitable for applications where a larger number of wires need to be connected in a relatively limited area.

For projects requiring fewer connection circuits, the same CMK42- series also includes CMK422-4 with 6 circuitsandCMK422-6 with 8 circuits.

Push-in Connection for Efficient Electrical Wiring

CMK422-8 features a push-in connection design that helps simplify the wiring process.

The orange operating levers provide convenient access to the internal connection mechanism. During installation, the appropriate lever can be operated to allow the conductor to be positioned in the corresponding connection point.

This structure can reduce repetitive tightening operations compared with conventional screw-based terminals.

For electricians working on projects with many connection points, reducing individual installation steps can make the overall wiring process more straightforward.

The independent lever structure also provides convenience during maintenance. If one conductor needs to be checked or replaced, the corresponding connection point can be accessed without unnecessarily disturbing other circuits.

Polycarbonate PC Connector Housing

The connector shell is made from Polycarbonate PC.

The housing provides structural support for the internal conductive and spring components while maintaining a compact overall design.

The material is suitable for electrical connection products used inside junction boxes, equipment enclosures, control panels, lighting systems, and other electrical installations.

The compact housing of CMK422-8 allows ten connection circuits to be arranged together without requiring a separate connector for every connection group.

This can be useful when installation space is limited and wiring organization is an important consideration.

PA66 Operating Levers

The operating levers are manufactured from Polyamide PA66.

The levers are designed to provide convenient access to each connection position.

Each circuit can be operated independently, allowing installers to work on a particular connection without unnecessarily affecting the surrounding circuits.

This feature can be useful during:

• Initial wiring
• Equipment assembly
• Electrical inspection
• Troubleshooting
• Wire replacement
• Routine maintenance

For equipment manufacturers, independent operation can also make internal wiring adjustments more convenient during production and servicing.

Tinned Copper Conductive Components

CMK422-8 uses tinned copper conductive parts for its internal electrical connection components.

Copper is commonly used in electrical connectors because of its good electrical conductivity.

The tin-plated surface helps provide additional protection against oxidation and corrosion.

The conductive components work together with the contact springs to maintain the electrical connection between the connector and the installed conductors.

Material selection is an important consideration when designing electrical connection products, especially for applications where stable electrical contact is required.

AISI 301 Stainless Steel Contact Springs

The internal contact springs are made from AISI 301 stainless steel.

The contact spring provides the mechanical pressure required to hold the conductor securely at the connection point.

AISI 301 stainless steel offers suitable mechanical properties for spring components and provides good resistance to corrosion.

Together with the tinned copper conductive parts, the stainless steel spring system forms the internal connection structure of CMK422-8.

Flexible and Rigid Wire Compatibility

CMK422-8 is designed to support both flexible and rigid conductors.

The specified wire ranges are:

• Flexible wire: 0.08–2.5mm²
• Rigid wire: 0.2–4mm²
• Connection capacity: 0.08–4mm²

This broad conductor compatibility allows the connector to be considered for different electrical installation and equipment wiring requirements.

The recommended wire stripping length is:

10mm / 0.39 inch

Correct conductor preparation and proper installation are important for achieving the intended electrical connection performance.

450V AC and 32A Electrical Rating

CMK422-8 is specified with:

• Rated voltage: 450V AC
• Rated current: 32A
• Working temperature: -40℃ to 105℃

These specifications make the connector suitable for a range of electrical connection applications.

However, the actual suitability of the product should always be evaluated according to the project requirements, conductor size, electrical load, installation environment, applicable regulations, and relevant standards.
