CMK204 4 Circuit Compact Wire Connector for Efficient Electrical Wiring
TheJINH CMK204 is a 4 circuit compact wire connector designed for electrical applications where several conductors need to be connected in a neat and space-conscious way.
As one of the models in the JINH CMK20 series, CMK204 provides four connection circuits within one connector body. It is positioned between the smaller 3 circuit configuration and the larger multi-circuit options in the same product family, giving users another choice when selecting a connector according to the number of required wiring points.
CMK204 combines a push-in connection method with a pluggable structure, making it suitable for electrical installation, equipment assembly, maintenance, and wiring projects where convenient operation is important.
The connector is designed for 0.5–2.5mm² rigid wires, with a rated voltage of 450V and a rated current of 24A.
Its transparent polycarbonate housing, tinned copper conductive parts, and AISI 301 stainless steel contact springs form a practical material combination for electrical connection applications.
Four Circuit Configuration for Multi-Wire Connections
CMK204 provides:
4 independent circuits
The four-circuit arrangement allows several electrical connection points to be brought together in one component.
In equipment with multiple wires, using separate single-position connectors can make internal wiring more complicated and increase the number of components required.
CMK204 provides four connection positions in one compact structure, helping installers and equipment manufacturers organize wiring more efficiently.
The four-circuit design can be useful for:
- Multiple wire connections
- Equipment wiring
- Lighting circuits
- Control wiring
- Junction box applications
- Electrical assembly
The number of circuits makes CMK204 a practical option for applications that require more connection positions than a 2 or 3 circuit connector but do not necessarily require a larger multi-circuit terminal.
Push-in Connection for Faster Installation
CMK204 uses a push-in wiring structure to make compatible conductor installation more straightforward.
Compared with traditional screw-type terminals, a push-in connection can reduce some manual tightening operations during wiring.
This can be especially useful for installers and equipment manufacturers handling multiple connection points.
The structure is designed around simple conductor insertion, helping make repetitive wiring tasks more convenient.
For production environments, a straightforward connection method can also help improve the consistency of the assembly process.
CMK204 is therefore suitable for electrical applications where installation convenience and wiring organization are both important.
Pluggable Structure for Flexible Applications
Another useful feature of the CMK20 series is its pluggable connection structure.
The pluggable design gives users additional flexibility during equipment installation and maintenance.
For equipment manufacturers, connectors can be incorporated into a structured wiring system during assembly.
For maintenance personnel, the pluggable configuration can provide greater convenience when equipment wiring needs to be inspected or adjusted.
Potential applications include:
- Electrical equipment
- Lighting systems
- Control panels
- Junction boxes
- Equipment wiring
- Electrical modules
- Building wiring
The combination of four circuits and a pluggable structure makes CMK204 suitable for applications where several wires need to be managed within an organized connection system.
0.5–2.5mm² Rigid Wire Compatibility
CMK204 is designed for 0.5–2.5mm² rigid wires.
This wire range is suitable for a variety of general electrical connection applications.
The recommended strip length is:
11mm / 0.43 inch
Correct conductor preparation is important during installation. The wire should be stripped according to the specified length and properly positioned inside the connector.
Before installation, users should confirm that the conductor type and cross-sectional area are compatible with the application and product requirements.
450V Rated Voltage and 24A Rated Current
CMK204 has a rated voltage of:
450V
and a rated current of:
24A
These specifications allow the connector to be considered for a range of electrical wiring applications.
Actual operating conditions may vary depending on the installation environment.
When selecting CMK204, users should consider conductor size, ambient temperature, electrical load, installation method, enclosure conditions, and applicable safety requirements.
The product should always be used within its specified electrical ratings.
Transparent Polycarbonate Housing
The connector shell is manufactured from:
Transparent Polycarbonate
The transparent housing allows users to see the connection area more easily during installation.
This can be useful when several connectors are positioned close together, as the visible structure makes it easier to check conductor placement.
Polycarbonate is widely used for electrical component housings because it offers a practical combination of mechanical properties and dimensional stability.
The transparent appearance also gives the connector a clean and easily recognizable structure.
Tinned Copper Conductive Parts
CMK204 uses:
Tinned Copper Conductive Parts
for the internal conductive components.
Copper is commonly selected for electrical connection products because of its electrical conductivity.
The tin-plated surface provides an additional protective finish to the copper component.
Inside the connector, the conductive parts work together with the contact springs to form the electrical connection path.
This material combination is suitable for a variety of electrical connection applications.
AISI 301 Stainless Steel Contact Springs
The contact springs are made from:
AISI 301 Stainless Steel
The spring components provide the contact force required to maintain the conductor connection.
AISI 301 stainless steel is commonly used for spring components because of its mechanical and spring characteristics.
The contact springs work together with the conductive parts and connector housing to create the internal connection system.
Working Temperature from -40°C to 85°C
CMK204 has a specified working temperature range of:
-40°C to 85°C
This temperature range allows the connector to be considered for a variety of indoor and outdoor electrical equipment applications where the environmental conditions fall within the specified range.
However, product selection should also take into account the actual installation environment, electrical load, enclosure conditions, conductor specifications, and other system requirements.
Applications of CMK204
Lighting Systems
CMK204 can be used in suitable lighting applications where multiple conductors need to be connected and organized.
Possible applications include:
- LED lighting
- Indoor lighting
- Commercial lighting
- Building lighting
- Lighting equipment
The four-circuit structure can help organize several connection points in one location.
Electrical Equipment
Modern electrical equipment often contains multiple internal connection points.
CMK204 can help organize these wires within a compact connector structure.
It can be considered for equipment assembly and internal wiring when its electrical specifications match the application.
Junction Boxes
The four-circuit configuration makes CMK204 suitable for selected junction box applications.
Several wires can be arranged within one connector, helping keep the internal wiring structure more organized.
Control Wiring
CMK204 can also be used for suitable control wiring applications.
The four independent circuits can provide several connection points for electrical equipment and control systems.
Building Wiring
For suitable building electrical applications, CMK204 can be used where the conductor specifications and electrical ratings meet project requirements.
Equipment Manufacturing
