Requirements for the development of connectors in industrial automation

In the field of modern industrial automation, connectors are responsible for data transmission between data sources and actuators and interconnection between execution devices. They are essential in ensuring the stable and efficient operation of modern factory automation production lines. At present, as the automation transformation process of large domestic factories continues to accelerate, equipment such as industrial robots have spread all over the production line. However, in order for industrial robots to achieve more flexible movement and operation and move towards "automation" in the true sense, the collaboration and empowerment of connector technology is the key. Currently, with the arrival of the 5G and industrial IoT wave, connectors for industrial robots must make more improvements and innovations in technology and product design in order to keep up with this rapidly developing new application demand, which also brings more and more connector companies that are deeply involved in the industrial field today bring new challenges. Keep up with the trend of automation: industrial connectors must be "exquisite" and "extreme". Electronic connector is a traditional electronic product, but it is widely used in many fields, ranging from consumer electronics to automobiles, industrial equipment and so on. Especially in the industrial sector, more and more factories are accelerating the transition from production lines to full automation. Affected by this, robot equipment, as the main force of automation, has naturally become the standard equipment of small factories or large workshops. Now, however, the space on the production line is becoming increasingly compact, which makes industrial robots smaller and smaller, especially when robots work in various harsh environments such as high vibration, high-speed movement and high temperature, which have special requirements for connection technology. The role of connectors is even more important.

In addition, with the gradual implementation of 5G high-speed transmission technology, while industrial connectors are miniaturized, stronger requirements are put forward for signal transmission capabilities. Therefore, it needs to be both small and high-speed. How should the two be balanced in terms of technology? In terms of data transmission, the amount of data transmitted by the connector itself is not necessarily related to the size of the product itself. In fact, the decisive factor of the transmission amount is the flow capacity of the current. The larger the current, the larger the corresponding conductor, otherwise it will burn it out once it heats up. For the transmission signal itself, there are currently two directions, one is the speed signal and the other is the RF signal, both of which are accumulated here. In terms of speed signal, it is basically a high-speed requirement. How to design high-speed transmission for industrial connector products requires between the pins of the signal, such as which pins need to be shielded. The development of 5G has moved from traditional high frequencies to microwaves. Microwaves, that is, under concepts such as 20GHz or 30GHz, can not only realize RF signals, but also minimize differential losses. As industrial robots, as application terminal equipment, are gradually developing towards miniaturization and low cost, the supporting connector products are also beginning to move towards "more refined" and "more extreme" on the premise of ensuring their basic performance (such as earthquake resistance, anti-interference, plug-in resistance, etc.). In addition, due to the drive of 5G and the trend of high automation, industrial robots also need to be equipped with more smart sensors. This application scenario full of "strenuous exercise" enables the connectors matching them (sensors) to ensure high reliability. At the same time, the need for signal integrity should also be taken into account as much as possible, which is the key for various manufacturers in the field of industrial connectors to achieve product competitive advantages.
