We are in the middle of the biggest transformation process in the automotive world: electric cars, hydrogen trucks, autonomous driving, software updates “over the air”, halving development times and new manufacturers who have never built a car before.
What remains: More than 2 km of wiring are installed in every vehicle. Thousands of connectors – on a circuit board or at the end of a cable – are responsible for propulsion, LED lighting, infotainment, climate control, driving assis-tance systems, charging … And the automotive industry’s digital offensive to make the connected world usable in the mobile world already requires longer wiring systems – and even more connectors.

These days, not a wheel turns without us: 800 car models from 100 brands rely on our connectors or complex sub-assemblies.

The right idea, a neat construction, fully-­equipped laboratories and precise system measurements are the primary steps in our developing projects. With state-of-the-art methods and technologies, we mobilize our established development expertise and our passion for feasibility for your product. It is not only about the creation of unique quality products. It is also about finding an answer for challenges where others fail to find a solution.

With our engineering-based-on-partnership maxim we manifest detailed and integrated made-to-measure solutions for you. How? By applying our comprehensive Automotive know-how and pairing it with our electrical and electromechanical engineering profession.

From a first talk about technology to the development, the design and the construction of a pre-­production prototype, we are a strong and reliable development partner. And we use creative thinking to turn even individual design and product requests into prime “Made by Lumberg” development quality at our R&D center.

Connectors mating directly with the circuit board edge are highly beneficial when installation space is limited. We have implemented many space-­saving applications using IDT in combination with modular direct mating systems, or even the respective guide frames for additional mechanical fixation or full modular assembly: the timely collaboration-based integration into your development processes is key here.

The automotive industry is currently focusing a great deal of attention on autonomous driving and safety systems – a similar revolution is in fact already taking place with the conversion of vehicle lighting to LEDs, which have a decisive influence on vehicle design today. Multi-pole direct connectors are also the solution here for developing space-­saving designs.

RAST 1.5: Top Miniaturization Achieved |new by Lumberg

„Home of the RAST Connector“ – Lumberg stands for this like no other connector manufacturer. RAST systems are the foundation of the company‘s success in automotive technology as well. In 1986, RAST 5 with a contact pitch of 5.0 mm made its debut. In the course of miniaturization, the RAST 2.5 system was introduced in 1993, which saved 72 % in size and opened up new applications, especially in automotive engineering.

Now, for the first time, RAST 1.5 in IDT is being launched. Compared to RAST 2.5, it saves another 43 % in size.

The characteristic RAST coding is available as well as the option of fully automated cable assembly. The weight saving due to reduced conductor cross-­sections is then 40 %.

RAST 2.5 for 1 mm PCBs | by Lumberg

Consistent: The RAST-2.5 connector, which has proven itself a billion times over and can be used up to 4 A, has also been further developed. Increasingly, 1 mm PCBs are being used where there are challenges in terms of confined installation spaces, desired weight savings or optimization of cooling, for example in high-performance LED headlights.

The connector now comes with a familiar layout: with contact spacing of 2.5 mm, with secure latching on the 1 mm PCB – and of course with the great advantage of economical and efficient automated cable assembly using IDT.

SmartSKEDD: While direct contacting on the edge of the printed circuit board with RAST connectors is one of our domains, and press-fit technology as an irreversible, solderless connection is our compulsory program, a new type of connector has been added to this line-up: the direct connector for multiple plug-ins and plug-outs that can mate without a corresponding part anywhere on the printed circuit board using Insulation Displacement Technology.
SKEDD technology makes this possible. The individual contact comprises two contact tongues which, when inserted into a plated-through hole in the PCB, retract evenly and produce a solderless, reliable mechanical electrical connection.

Extra robust and reliable:
SnapFit locking

Three solid pins on each casing guarantee a secure positioning and prevent mismating. And there is more: each side of the connector features two snap-fits that lock – or rather: snap – the connector tightly onto the PCB. To release the connector, simply press on the primary lock.
Connectors can be mated without tools, for total convenience when mounting entire sub-assemblies. This enables completely new designs since they can be used right in the middle of a printed circuit board, even on the reverse. Here, reversible mating also facilitates for the first time a simple exchange of components as is required, for example, during servicing. In combination with Insulation Displacement Technology which draws on all advantages offered by automated cable assembly and vouches for the convenient production of even large quantities, our unparalleled solution that literally centers your ideas on the PCB is really smart – or simply: SmartSKEDD.
If a secondary lock is what you need – as is standard under LV 214 – or if your application just calls for that extra measure of retention, you can count on a pre-assembled central pin which increases the retaining force of the entire system to almost 100 N.

Press-fit technology is a superior solderless me­chanical/electrical method with many benefits especially for the automotive industry. This connection is characterized by a defined deformation of the contact pins’ press-fit zones whren pressed into the PCB’s plated-through holes, as defined by IEC 60352-5.

This sealed, non-ageing connection eliminates cor­rosion and guar­antees high mechanical stability. With improved FIT (Failure-in-Time) rat­ings of up to 30 times, this technology creates design op­por­tunities and high packing densities for many au­tomotive applications. The solderless method not only erases soldering costs: additionally, the PCB as well as ad­jacent components are no longer ex­posed to the stress caused from the high tem­per­atures associated with soldering.

We precision-punch our press-fit contacts in-house and can customize them for use with your indivi­dual project, such as the integration into mecha­tronic sub-assemblies.

Lumberg has been producing customized high-­current contacts for automotive applications for more than 20 years. Millions of these are installed in mechatronic modules and control units in particular, especially in electric vehicles. They are also recommended for use in frequency converters for industrial electric motors.

In tight installation spaces, the versatile and robust high-current contacts – which are particularly space-saving – connect stacked PCBs optimally. The high-current contact is soldered onto the circuit board (SMT or THT) and makes vertical contact with a tab contact on the second circuit board. It can just as easily be laser-welded onto a busbar.

All high-current connectors are compatible with many commercially available tab contacts. The tab contact can be inserted from up to three directions – top, bottom, and side.
