YK8810403000G application field and working principle

The YK8810403000G (hereafter YK) series terminal block is a type of barrier blocks that are popular for use in a broad range of applications. They are designed to provide reliable and easily accessible electrical connection with low contact resistance. The YK series terminal blocks feature a solid insulation barrier with a choice of either knob or screw clamping for a secure connection.

Terminal Blocks - Barrier Blocks: General Overview

Barrier blocks are an extension of the traditional terminal block, a single-piece device used to provide electrical connections between two or more wires. The main difference between a terminal block and a barrier block is that the former normally only carries DC electricity, while the latter carries DC and AC electricity between two or more points.

Barrier blocks, like the YK series, are generally composed of four components: body, terminal, clips, and insulators. The body is often made from a die-cast zinc alloy, with some models made from molded plastic for cost-effectiveness. The terminals are typically spring loaded and are secured with a lock-nut to ensure reliable contact.

The clips are used to secure the wires onto the terminals. They can be either flat, which use a sharp prong to pierce the insulation of the wire, or round, which relies on a crimp to make secure contact. The insulators, usually made from a self-extinguishing material like a high-impact polycarbonate, protect the wiring and the terminals from short circuits.

YK8810403000G Series Application Field and Technical Specifications

The YK8810403000G series terminal block is a type of two-level, dual-row barrier block. It is available in simple one- and two-pole configurations, as well as more complex multi-pair combinations with different conductor sizes and configurations. The YK8810403000G series can accept conductor sizes ranging from 0.2 to 4mm².

The YK terminal blocks are suitable for a wide variety of industrial, commercial, and domestic applications. It is commonly used in switchboards, telecommunication systems, automation systems, and various other industrial electronics. The YK8810403000G series is designed to operate under various environmental conditions ranging from -30°C to +80°C.

YK8810403000G Series Working Principle

The YK series terminal block works on an external “knob” or “screw” principle. In the former configuration, the user simply tightens the knob on the front to secure the wires. In the latter design, the user needs to clamp each of the wire separately using a screwdriver. This ensures reliable contact and provides a secure connection.

In addition, the YK series terminal blocks offers superior resistance to corrosion, vibration, and mechanical shock due to its specially designed “anti-vibration” system. This system prevents vibration from affecting the reliability of the electrical connection.

Conclusion

The YK8810403000G series terminal block is a type of two-level, dual-row barrier block that is suitable for a wide variety of industrial, commercial, and domestic applications. It offers reliable and easily accessible electrical connections with low contact resistance. In addition, its anti-vibration system ensures reliable and secure contact of the wires.
