Heavy duty connector has now slowly replaced some of the traditional terminal functions of the past, science and technology to change the production, its emergence is slowly from abroad back to the domestic, by several domestic enterprises specializing in the production of heavy duty connector technology, greatly improve the reliability of the connection, stability, reduce the installation time.
Heavy duty connectors generally have four connection methods:
1. Thread connection 2. Bayonet connection 3. Plug and pull connection 4. Cabinet connection
1. Thread connection of Heavy duty connector:
A form of connection often used by some electrical connectors with larger size contacts and operating in strong vibration environments. This connection form can be fitted with a fuse to prevent loosening after the connection is completed. The connection is reliable, but the unloading speed is slow.
2. Bayonet connection of Heavy duty connector:
It is a reliable and rapid form of connection and separation. Most electrical connectors in the form of buckle connections have a visual display of the correct connection and locking, which can be observed from the small hole on the side of the electrical connector connection nut.
3. Plug and remove connection method of Heavy duty connector:
It is a form of connection with multiple uses. The electrical connector plug and socket in the connection and separation of the direction of movement is usually reciprocating linear motion, do not need to twist and rotate, only need a small working space to complete the unloading. The common plug and pull connection has two kinds of structure, ball or pin. Because the connection form has no mechanical labor-saving mechanism, once it is mistakenly inserted, the mechanical resistance increases significantly, and it can be found in time.
4. Cabinet connection:
It is a heavy-duty connector for some equipment that needs to be blindly connected near the frame, which can make electrical equipment lighter, easier to maintain and more reliable.
This connection form makes the operator unable to feel the connection, and an accurate positioning device must be designed to avoid forcing the misinserted electrical connector to be connected together, making misinserted impossible. Cabinet electrical connectors of Heavy duty connector usually use a floating or elastic contact design structure to ensure their correct connection.
Advantages of heavy duty connector
1, the realization of pre-installation, pre-installation of a large number of complex circuits, can greatly improve the installation efficiency of equipment, reduce the wiring error rate.
2, heavy duty connectors provide highly integrated connections, rich combinations to maximize the effective use of equipment space.
3, heavy connector connector can conveniently and efficiently achieve the modular structure of the functional template block of the equipment, so that the transportation, installation, maintenance and repair of the equipment is convenient and safe. Connectors are widely used in power transmission and distribution fields.
4, heavy duty connectors provide high protection levels (IP65, IP67) for the advantages of equipment connection systems in harsh environments is unparalleled. In the dust, rain, cold, snow, oil and other harsh environment to provide effective protection.
Heavy-duty connectors, also known as heavy-duty sockets, are widely used in engineering machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives, petrochemical electrical equipment and so on that require electrical and signal connections. The international advanced nature of heavy-duty connectors in structural design and material use makes the connectors outstanding in electrical performance. The reliability of electrical connection system can not be achieved by traditional connection.
The main areas of connector
Industrial applications, such as railway and communication high-current connectors, PC board connectors, coaxial cable connectors, backplane connectors, high-frequency converters, etc.
the main difference
Basically no difference, the literal meaning can be understood, the range of connectors is very wide, and the overload is only used on specialized equipment.
Application
Heavy duty connectors are widely used in engineering machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives and petrochemical electrical equipment that require electrical and signal connections.
Heavy-duty connectors are strictly standardized connectors, but there may be some failures caused by poor contact during use, and the following will introduce it to you.
1. Poor insulation of heavy duty connector
The function of the insulator is to keep the contacts in the correct position, and to insulate each other between the contacts and the contacts, and between the contacts and the shell. Therefore, the insulation parts must have excellent electrical properties, mechanical properties and process forming properties.
2. Improper fixation of heavy duty connector
Insulators not only act as insulation, but also usually provide precise neutralization protection for extended contacts, but also have the function of installation positioning, locking and fixing to the equipment. Poor fixation, light impact contact reliable cause instant power failure, serious is the disintegration of the product. Disintegration refers to the terminal in the plug state, due to material, process and other reasons caused by the structure is not reliable between the plug and socket, pin and jack between the abnormal separation,
will cause the control system power transmission and signal control interruption of the serious consequences.
3. Poor contact of heavy duty connector
The metal conductor inside the terminal connector is the core part of the terminal, which transfers the voltage, current or signal from the external wire or cable to the corresponding contact with its matching connector. Contact parts must have excellent structure, stable and reliable contact retention and good electrical conductivity, so it is also crucial in material selection.
When choosing and using heavy-duty connectors, you need to pay attention to the following:
1. Select the appropriate connector model and specifications according to the current, voltage, temperature and other parameters of the connector.
2. Confirm whether the material of heavy duty connector is suitable for the required environment, such as high temperature resistance, corrosion resistance, etc.
3. Check whether the waterproof and dustproof performance of heavy duty connector meets the requirements, especially when used in outdoor or humid environments.
4. Confirm the reliability and life of heavy duty connector, and carry out necessary maintenance and maintenance.
5. During the installation and disassembly of heavy duty connector, pay attention to avoid damaging the connector, wire and circuit board, etc., and ensure that the connection is correct, stable and reliable.
6. During the use of heavy duty connector, pay attention to the working status of the connector to discover and handle the fault in a timely manner.
According to the requirements of heavy duty connector, take relevant protective measures, such as lightning protection, ESD protection, and overcurrent protection.
The above are several forms of heavy duty connector connection, different connection forms are suitable for different application scenarios, need to be selected according to actual needs. At the same time, the choice of the correct connector model, material, connection and installation methods also need to be studied and considered according to the specific situation.
Heavy-duty connectors are a kind of connectors, mainly used in many fields such as industrial automation, equipment manufacturing and industrial system buildings, as well as information and control technology, and are therefore called “industrial connectors”. The use of heavy-duty connectors not only helps manufacturers save installation time and reduce production costs, but also allows users to enjoy a more effective and convenient experience.
Heavy duty connectors are definitely a significant presence in connectors. Because it is designed to withstand the test of the most harsh industrial environment, it is widely used in construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, robots, rail transit, hot runner, power, automation and other equipment requiring electrical and signal connections. Stronger and more resistant than other connectors.
