According to STÜKEN, the deep-drawing specialist from Rinteln, connections are the lifeblood of our economy. Advances in wireless data transmission have led to ever-increasing networking, and above all, the advent of electric mobility has created a number of new challenges in the field of cables and connectors. With metallic shielding and components for plug connectors, STÜKEN has long been helping to maintain good contacts. Thanks to the innovative deep-drawing technology of the Lower Saxony company, the geometry of the components is virtually unlimited.

Connectors are everywhere. They transmit power, data, optical and acoustic signals, thus connecting devices or components. They are used in automotive and industrial applications, in data technology and telecommunications, as well as in household and entertainment appliances. High-frequency technology is a driver of innovation. Thanks to wireless data transmission – keyword 5G – unprecedented networking on an unprecedented scale is possible. Future technologies such as Industry 4.0, autonomous driving and the Internet of Things would be inconceivable without connectors. New frequency ranges, the highest level of signal quality and growing amounts of data also mean new challenges for connectors. Cables and connectors are sensitive to electromagnetic radiation – thus shielding is essential. “Here we can offer metallic shielding of the highest precision based on years of experience,” explains Nils Petersohn, managing director at STÜKEN. “We provide our customers with comprehensive advice: from material selection to finishing. Our primary goal is for the customer to be successful in the market with his system.”

Another topic is the ongoing miniaturization. Processors and memory are becoming more and more powerful, enabling developers to make their systems smaller, more complex and more intelligent. The goal is to achieve the highest possible performance with the smallest possible size. “We deliver micro parts with dimensions of less than one millimeter every day in reliable quality and in high volumes. Our range also includes very long sleeves with a very small diameter. In connection technology, such sleeves are used in contact pins, for example,” explains Petersohn.

Electromobility is also a growth driver for the demand for connectors. ”In the high-voltage wiring systems of electric and hybrid vehicles, the components are subject to higher loads, for example in terms of temperature. The design of the components, the choice of materials and the contact surfaces must be designed to meet these requirements. Electromagnetic compatibility must be incorporated into product development and design at an early stage,” emphasizes Petersohn. ”STÜKEN products already fulfill many functions in electric vehicles. We understand the requirements and can advise our customers. Often, a compact design and low weight play an important role. Due to the material solidification during the cold forming process, deep-drawn parts are inherently lightweight components. And there are almost no limits to the component geometry at STÜKEN: whether round, square or oval, whether combinations of these or even free forms – our developers, toolmakers and deep-drawing production make it possible,” says Petersohn.
