Industrial Connectors

Connector is system or the electrical connection between the machine circuit unit or signal transmission indispensable key components, has been widely used military-industrial complex, communications, automotive, consumer electronics, industrial, and other fields.

Industrial connectors are designed for Ethernet connections in harsh environments and have the advantage of being tougher and more resistant than other types of connectors.

The connection form of industrial connector can be divided into several kinds? Generally, it can be divided into four forms.

1. Threaded connection: A type of connection often used by some large size contacts and electrical connectors working in a strong vibration environment. This type of connection may be fitted with a loose fuse after completion of the connection. The connection is reliable, but the connection is slow.

2. Bayonet connection: It is a reliable and rapid connection and separation form. Most electrical connectors in the form of buckle connections have a visual display of the correct connection and lock, which can be viewed from the holes on the side of the electrical connector connection nut.

3. Plug connection: It is a multi-purpose connection. When the plug and socket of the electrical connector are connected and separated, their movement direction is usually reciprocating straight line movement, no need to twist and rotate, only a small working space can be completed. Common plug connections have ball or pin structure. The connection form because there is no mechanical labor-saving mechanism, once mistakenly inserted, mechanical resistance significantly increased, can be found in time.

4. Cabinet connection: It is used for the electrical connector on some devices that need blind connection close to the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. This type of connection makes it impossible for the operator to feel the connection, so an accurate positioning device must be designed to avoid forcing the misinserted electrical connectors together and making misinserted connections impossible. Cabinet type electrical connectors usually adopt floating or elastic contact design structure to ensure their correct connection.

At present, the development speed of China connector market is much higher than the average level of global connector development, and it has become the largest connector market in the world. The reliability of connectors in industrial and aerospace applications has been challenged by the Chinese connector market. At this time in order to improve the quality of connector products, reliability and reduce costs, connector miniaturization, high-speed, automation development trend is extremely important.

Connector miniaturization:

Because connectors usually work in all kinds of harsh environment, all kinds of difficult conditions, reliability must be the primary technical requirements of industrial connectors. Only with reliable quality can we reliably communicate circuits, transmit information, achieve specific functions, and guarantee the reliable work of engineering systems such as rockets and missiles. In aerospace applications, for example, according to the failure rate of America's aerospace failures, about 20-30% of the 40% of component failures are caused by electrical connector failures. In the history of China's aerospace industry, there have been some important events that caused the delay of launch due to the failure of the electrical connector.

High speed of connectors:

At present, the armed forces have increasingly high requirements on coordinated and integrated combat capabilities, and increasingly high requirements on informatization and intelligence of weapons and equipment. All kinds of weapons are being upgraded and replaced at an accelerated pace in the direction of electronization. The proportion of electronic components represented by connectors is also being significantly increased. As an important connection device for signal transmission, the connector has a great impact on the quality and speed of signal transmission, which puts forward higher requirements for high-speed connector. At present, the network data transmission rate has stepped into the gigabit per second, the communication mode has become a full-duplex, multi-task situation, which requires the aviation connector not only have high frequency transmission, fast networking, but also to achieve micro configuration and high density.

Connector automation:

Production automation is increasingly important in ensuring the accuracy and yield of products related to avionics connectors and interconnect systems, shortening lead times and reducing labor costs. With the continuous development of industrial connector and interconnection system related products to miniaturization, the reliability of manual assembly and inspection has been unable to meet the quality requirements of products. For some products, automated assembly is required to achieve the precision required by the downstream industry. At the same time, the automatic production line can achieve long continuous operation, the delivery cycle of products to grasp the degree of high, reduce the complexity of production management and improve the guarantee of customer satisfaction. More importantly, with the deepening of civil-military integration, competition intensifies, and labor costs are also rising, so the automation transformation can greatly improve production efficiency and save a lot of labor costs.

Lightweight, high reliability, and easy to use are the main demands of today's user market for emerging hot industrial applications such as electric vehicles, high-speed rail vehicles, civil aircraft, power tools, and industrial brake machines. At the same time, industrial connectors will develop in the following three directions in the future.

The first trend is that the weight of industrial-grade connectors and related connection cables must be reduced to extend the life of the corresponding functional modules.

The second trend is to improve the robustness or stability of industrial-grade connectors, especially for the aerospace airborne and automated instrument applications market;

A third trend is the development of rapid-plug connector technology, which is becoming increasingly important in industrial-scale field applications because users are unwilling and unable to go back to the lab to get the right tools to match or remove the connectors in the field.
