High voltage interlock connector principle analysis - What role does it have? from Nancy Guan's blog

The high-voltage interlocking connector is used for high-voltage electrical appliances, cables, and other occasions of electrical connector, with waterproof, anti-fouling, shock-resistant, and other characteristics, to meet the demand for wire and cable connection interfaces, but also to protect the line and the safety of the equipment, and effectively prevent the fire caused by power failures, short circuits, and other hazards. Want to better use this connector, then first come to understand the principle of a high interlock connector, and its function.

The principle of high-voltage interlock connector

The high-voltage interlocking connector is used for high-voltage electrical appliances, cables, and other occasions of electrical connectors, with waterproof, anti-fouling, shock-resistant, and other characteristics, to meet the demand for wire and cable connection interfaces, but also to protect the line and the safety of the equipment, effectively preventing fire caused by power failures, short circuits, and other hazards. Want to better use this connector, then first come to understand the use of the high interlock connector principle, as well as its functional role.

Principle of High Voltage Interlocking Connectors

I. Structure

The structure of the high-voltage interlock connector, including the plug end, the insertion port, the interlocking mechanism, ordinary contacts, its frame, and the through-hole emergency stop interface, etc., the basic components are the interlocking mechanism and contacts.

1, interlocking mechanism: the interlocking mechanism is divided into the body and swing back and forth mechanism, the body is usually embodied in a barrel-shaped structure, the swinging mechanism is often completed inside the body of the body to rotate, the guiding frame is equipped with a contact center at both ends to ensure that the body of the body will not be physically impeded by the rotation.

2, contacts: contacts have one or more interfaces, there are one or more needle width fixed, in wiring with different insulation materials to break the formation of circuits, contacts are divided into two categories of main contacts and subcontracts, two interfaces with positioning holes between the two can be placed on the cover plate and contact bearing frame.

Principle

High-voltage interlock connector control device for mechanical and electrical short-lock, which not only protects the equipment from misuse, but also avoids possible electric shock due to misuse, and other serious dangers.

When the connector socket of the high-voltage interlock connector contacts a certain equipment plug, the interlocking mechanism is scattered, and automatically locked, to realize the electrical connection, in this state, any error operation, making the mechanism mechanically locked, the connector can not be disassembled.

When the equipment is in the power-off state or the equipment hub is not open, the interlocking mechanism of the swing system will be in the anti-stay word ring to form a closed state, the formation of a fixed interlocking, in the insertion of the socket, press the handle can be loosened interlocking mechanism. This realizes the functions of interlock connection and operation, which can effectively protect the safety of high-voltage electrical appliances as well as the transmission stability of electrical lines.

Features

1. A High-voltage interlocking connector can withstand the characteristics of high current, usually applied to high-voltage electrical appliances, cables, and electrical lines for the stability of the connection, and its insulating materials are designed to prevent the current is too large.

2. The High-voltage interlock connector mechanical structure is simple, easy to install, very convenient, and simple to use, while it has a strong anti-fouling, waterproof, corrosion-resistant, shockproof performance, and other characteristics, able to work stably in a variety of harsh environments.

3. The interlocking mechanism of the high-voltage interlocking connector can prevent accidental danger caused by operation errors.

4. The high-voltage interlock connector can detect whether the mechanical locking pressure meets the requirements in time during the use process to ensure the safety of the equipment.

Role of high-voltage interlock connector

1、Anti-misoperation

High-voltage interlock connectors rely on an interlocking mechanism to realize the connector interlock when the equipment is in the closed state, the interlocking mechanism is automatically along the swing mechanism of the clockwise direction of movement, and other contacts contact, this time to complete the electronic contact, the equipment can be normal circuit pathway.

At the same time, when the equipment is in the power-off state or the equipment hub is not open, the interlocking mechanism of the swinging system will be formed in the ring of the word to prevent the closed state, the formation of a fixed interlocking, so that it can be realized on the prevention of misuse of electrical equipment.

2. Protection against electrical hazards

The high-voltage interlock connector interlocking mechanism is characterized by ensuring that the connector is in a safe state, to avoid high-voltage circuits due to excessive electricity or current caused by an explosion or some serious electrical hazards when the equipment is opened, the interlocking mechanism through the mechanical interlocking to ensure that the electrical connection of the electrical equipment connected to the safety of the connection, and at the same time to achieve the high-voltage protection of electrical appliances and the safe operation of the equipment to ensure the continued stable operation of the equipment for a long time. This can ensure the long and stable operation of the equipment.

3、High reliability

High-voltage interlocking connectors in the connection of precision structure and interlocking mechanism, after rigorous inspection and testing to ensure the reliability of the connection, in the connection, interlocking connector handle will enter the lock position, at this time the handle will not be able to start, and at the same time interlocking connectors between the signs, will be dealt with and the formation of a closed state between the wires to ensure that the connector is clean and stable connection.

4. Simple and safe operation

High-voltage interlock connector operation is very simple, only need to press the handle of the interlock connector can be completed with a wire jack plug connection, when the plug is into the socket, the interlocking mechanism will be fixed in the socket plug, to achieve a stable electrical connection state, can ensure that the equipment for a long time to continue to operate stably!
