High Current Carrying Capacity
The WK20 series is typically designed for currents up to 20A and voltages up to 250V. These specifications enable it to easily handle the power demands of most high-power power tools (such as angle grinders, rotary hammers, and circular saws) and equipment. The internal metal terminals are constructed from high-quality materials and feature a robust structural design, ensuring low heat generation, high efficiency, and safe and stable operation even under high current conditions.
Quick Connect and Easy Connection
Lock Hook Design: The male and female connectors connect easily and directly. Align and push until an audible click indicates they are locked, and the connection process takes only one second. Once connected, the internal self-locking latch securely locks the connectors in place, preventing them from accidentally falling out due to vibration, pulling, or movement, ensuring power continuity. Compared to traditional terminal blocks that require screws or soldering, the WK20 significantly improves production, assembly, and maintenance efficiency.
Anti-Mistake and Reverse Connection Design
Both the male and female connectors feature unique grooves that ensure insertion only when correctly oriented, preventing short circuits or reverse connection damage caused by misconnection. This is its most notable external feature.
Fully Enclosed Insulated Housing
The housing is made of high-strength, flame-retardant PA66 engineering plastic, completely encasing the metal conductive parts to effectively prevent electric shock and external short circuits, complying with safety regulations. The material is stable and can withstand a wide temperature range.
Excellent Mechanical and Environmental Performance
The housing is impact- and extrusion-resistant, making it suitable for rugged use in industrial and mining environments. It also boasts IP68-rated waterproofing, and its tight mating structure provides strong protection against dust and splashes.
Standardization and Wide Compatibility
The WK20 is a variant of the industry-standard M20 circular connector. This means the WK20 connector is compatible in both physical dimensions and electrical performance, making it easily available in the supply chain and reducing replacement costs.
Applications
Power Tools
Power input port for the tool body (such as angle grinders and electric drills).
- Quick Accessory Change: For interchangeable chucks (such as those for marble saw blades on some angle grinders), users can instantly disconnect the power cord and change them without tools, significantly improving work efficiency.
- Safety: The anti-mistakable plug-in design prevents reverse polarity, protecting the tool motor from burning out. The fully insulated housing prevents electric shock.
- Reliability: The self-locking mechanism ensures it will not loosen even under high-intensity tool vibration.
Home Appliances and Kitchen Appliances
Commercial or high-power kitchen appliances, such as blenders, grinders, and commercial coffee makers.
- Easy Storage and Cleaning: The power cord can be easily unplugged and coiled for storage or cleaning separately from the appliance body, eliminating the need for dragging the entire cord.
- Shared Power Cord: Appliances of the same specifications within a home or kitchen can share a single power cord, saving cost and space.
Outdoor Power Supplies (UPS) and Generators
AC output port for small and medium-sized uninterruptible power supplies (UPS), outdoor power banks, and portable generators.
- Plug-and-play: Users can quickly connect the power cords of devices like rice cookers, electric fans, and laptops to the power supply.
- Safety: Clear polarity markings and a design that prevents incorrect insertion ensure correct connection, eliminating the risk of device damage caused by reverse connection.
Industrial Equipment and Instruments
1) Lighting Equipment: Photographic lights, stage lights, and industrial work lights.
2) Testing Equipment: Portable measuring instruments and sensors.
3) Small Mechanical Equipment: Small tooling equipment used in production lines.
- Improved Maintenance Efficiency: In the event of equipment failure, maintenance personnel can quickly disconnect the power cord for repair or replacement.
- Durable Mechanical Performance: Withstands the bumps and strains of industrial environments.
Gardening Tools
Power connections for lawn mowers, hedge trimmers, hair dryers, and other equipment.
- Easy Storage: Long power cords can be coiled and stored separately, eliminating the need to take up space on the device itself.
- Safe Operation: Quickly disconnect the power cord when leaving or changing operators, making it quicker than unplugging.
Audio and Stage Equipment
Provides power connections for some powered speakers, power amplifiers, or effects pedals.
- Quick connection facilitates quick setup and removal of equipment on stage.
