CMK422-4 6 Circuit Connector for Multiple Wire Connections

TheJINH CMK422-4 is a 6 circuit push-in quick connector developed for electrical installations where several conductors need to be connected in a compact and organized space.

As one of the models in the JINH CMK42- series, CMK422-4 is designed around practical wiring requirements rather than simply adding more connection points. Its six-circuit structure allows multiple wires to be managed within one connector body, helping installers keep related connections together.

The connector combines a compact PC housing with easy-to-operate levers and reliable internal conductive components. This makes it suitable for electricians, electrical equipment manufacturers, panel builders, distributors, and other users who need a convenient solution for multi-wire connections.

CMK422-4 supports both flexible and rigid conductors, giving installers more flexibility when selecting wires for different projects.

Six Circuit Structure for Better Wiring Organization

One of the main features of CMK422-4 is its 6 circuit configuration.

When a project contains several electrical connections, using too many individual connectors can make the wiring layout difficult to organize. CMK422-4 brings six connection circuits together in one compact component, helping reduce unnecessary parts and keeping the wiring arrangement more structured.

This makes the connector particularly useful for applications such as:

• LED and general lighting systems
• Junction boxes
• Electrical control panels
• Distribution connections
• Automation equipment
• Machine wiring
• Building electrical installations
• Internal equipment wiring

The six-circuit format provides a practical balance between connection capacity and installation size.

For applications requiring more circuits, the same CMK42- series also includes CMK422-6 with 8 circuitsandCMK422-8 with 10 circuits, allowing customers to select a suitable configuration according to their wiring requirements.

Push-in Connection for Faster Installation

CMK422-4 uses a push-in quick connection structure to simplify the wiring process.

Instead of relying on traditional screw tightening, the connector is designed for straightforward conductor insertion. The operating levers provide access to the connection mechanism and can be opened when installing or removing wires.

This can be useful during projects where electricians need to connect a number of wires within a limited working time.

A simpler connection process can also make later inspection and wire replacement more convenient. When a circuit needs to be checked or modified, the corresponding lever can be operated without disturbing the other connection points.

For installers, this means less repetitive work and a cleaner wiring process.

Durable Polycarbonate PC Housing

The connector shell is manufactured from Polycarbonate PC.

The PC housing provides a solid structure for protecting the internal connection components while maintaining a compact form.

Its practical housing design is suitable for use inside electrical boxes, equipment enclosures, lighting installations, and control systems.

The gray housing and colored operating levers also make the connection points easy to recognize during installation.

For equipment manufacturers and electrical installers, a well-structured housing can help simplify assembly and improve the overall appearance of finished wiring.

PA66 Operating Levers for Convenient Handling

The operating levers are made from Polyamide PA66.

The levers are designed to provide convenient access to each connection circuit. Since each circuit can be operated independently, installers can work on a specific connection without unnecessarily disturbing the surrounding wires.

This is useful not only during initial installation but also during troubleshooting and maintenance.

The lever structure makes CMK422-4 a practical option for electrical projects where wiring may need to be adjusted or inspected after installation.

Tinned Copper Conductive Parts

The internal conductive components are made from tinned copper.

Copper is widely used for electrical connections because of its good conductivity. The tin-plated surface provides additional protection against oxidation and helps support long-term connection performance.

The conductive parts work together with the contact springs to maintain electrical contact with the connected conductors.

For applications where stable electrical performance is important, selecting suitable conductive materials is an important part of the connector design.

AISI 301 Stainless Steel Contact Springs

CMK422-4 uses AISI 301 stainless steel contact springs inside the connection mechanism.

The contact spring is responsible for maintaining pressure at the electrical contact area. A stable spring structure helps keep the conductor securely positioned within the connector.

AISI 301 stainless steel is also known for its mechanical properties and corrosion resistance, making it suitable for spring components used in electrical connection products.

Together with the tinned copper conductive parts, the spring system forms the internal connection structure of CMK422-4.

Flexible and Rigid Wire Compatibility

CMK422-4 is designed to accommodate 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 range gives customers flexibility when selecting conductors for different electrical projects.

The recommended wire stripping length is:

10mm / 0.39 inch

Proper wire preparation and correct insertion are important for achieving reliable electrical contact.

Electrical Performance

CMK422-4 is rated for:

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

These specifications make CMK422-4 suitable for a wide range of electrical wiring environments.

Before selecting the connector for a specific project, users should always verify that the actual electrical load, conductor size, installation environment, and applicable standards are compatible with the product specifications.

Applications of CMK422-4

The compact six-circuit design allows CMK422-4 to be used across different wiring applications.

Lighting

CMK422-4 can be used in LED lighting, lighting fixtures, and other electrical lighting connections where several conductors need to be organized together.

Junction Boxes

The multi-circuit structure is suitable for junction boxes where several wires need to be connected within a relatively small space.

Control Panels

Control panels often contain numerous individual circuits. CMK422-4 can help organize multiple conductors and keep wiring layouts more manageable.

Electrical Equipment

Equipment manufacturers can use the connector for internal wiring, assembly, and electrical connection points.

Industrial Wiring

The connector can also be used in machine wiring, automation equipment, and other industrial electrical applications where convenient multi-wire connections are required.

CMK42- Series Connection Options

CMK422-4 belongs to the JINH CMK42- series and is designed together with different circuit configurations.

The available models shown in the series include:

CMK422-4 — 6 circuits

For six circuits, CMK422-4 provides a compact option. When additional connection points are required, CMK422-6 and CMK422-8 offer higher circuit capacities while following the same general product design.

A Practical Choice for Electrical Connection Projects

Choosing a suitable connector is not only about the number of circuits. Installation space, wire compatibility, operating convenience, material selection, and electrical requirements all affect the final application.

CMK422-4 brings these considerations together in one compact product.

Its six-circuit structure helps organize multiple wires, while the push-in connection design makes installation more straightforward.
