Automotive OEM: The "Reliable Heart" of New Energy Vehicle High-Voltage Connection Systems
A global leader in new energy vehicle manufacturing encountered a critical technical challenge during the development of a next-generation plug-in hybrid electric vehicle platform — connection points between the battery pack, high-voltage heaters, and propulsion systems were experiencing excessive temperature rise under high-current conditions, straining the vehicle's thermal management system and triggering multiple protective system shutdowns. Traditional bolted connections were not only time-consuming to install but also carried risks of contact loosening under high-vibration environments.
After extensive evaluation, the OEM's electrical engineering team selected a high-current connector system as the high-voltage connection solution. This connector features patented terminal contact technology, utilizing a stainless-steel spring to maintain constant contact force and a copper current carrier for maximum conductivity — delivering stable electrical performance even after repeated thermal cycling. The connector is rated up to 270A, offers 30-60% higher power density than conventional solutions, and enables tool-free mating — achieving secure connections with just 70 newtons of insertion force.
"Battery high-voltage connections used to require torque wrenches and several minutes per workstation. Now workers can complete the job by hand — assembly efficiency has multiplied," commented the OEM's production lead. Since the new platform entered production, high-voltage connection system failure rates have dropped by over 85%, significantly improving overall vehicle operational reliability. This high-current connector solution has been designated as the standard configuration for multiple future electric platforms from this brand.
Industrial Equipment OEM: The "Power Joints" of Heavy Machinery
A leading European construction equipment manufacturer faced a persistent industry challenge while designing a new generation of large excavators — equipment subjects connectors to continuous high-intensity vibration during operation, causing terminal wear and intermittent contact failures that lead to sudden power outages. For heavy equipment in mines and construction sites, every unplanned shutdown translates into hundreds of thousands of dollars in production losses.
The OEM collaborated with connector suppliers to develop a customized high-current connector solution. The design incorporates multi-spring contact points and an anti-vibration locking mechanism, ensuring stable electrical connections even under V2-level vibration conditions. The connector operates across a temperature range from -40°C to 125°C, adapting to everything from Arctic permafrost mining to scorching desert environments.
"Our equipment goes everywhere — from Siberian tundra to African mines. Connectors must withstand any environment," said the manufacturer's chief engineer. With the new solution, equipment downtime due to connection failures has been reduced by 70%, with customer satisfaction reaching new heights. This high-current connector solution has been rolled out across the brand's entire construction equipment lineup, setting a benchmark for high-reliability connections in the industrial equipment sector.
Energy Storage System OEM: The "Energy Hub" of Containerized Storage
With the explosive growth of the global energy storage market, an OEM specializing in commercial and industrial energy storage systems secured a major contract to deliver a batch of containerized energy storage systems for a large industrial park, with single-system power reaching megawatt levels. The core challenge: connections between the power conversion system (PCS) and battery racks needed to carry sustained high currents while achieving high-density wiring within the confined space of shipping containers.
The OEM's traditional approach used copper busbar bolted connections — extremely difficult to install in tight container spaces and even more challenging to maintain. Through deep collaboration with connector suppliers, they introduced a high-current connector pluggable solution — connectors rated up to 1400A, with operating voltages up to 3.6kV and IP68/IP69 protection ratings to meet the demanding requirements of energy storage systems.
"Busbar connections used to take two days per storage cabinet. Now with pluggable high-current connectors, we complete all connections in half a day — and maintenance is tool-free disconnection," said the OEM's project manager. The new solution reduced assembly time by 75%, lowered connection point temperature rise from over 60°C to under 30°C, and improved system power transformation efficiency by nearly 2%. This connection solution has become the standard configuration for the OEM's storage products, giving them a significant delivery-speed advantage in a competitive market.
Robotics OEM: The "Power Neural Network" of Intelligent Robots
An OEM focused on intelligent robotics research and development is developing a next-generation humanoid robot product. The robot features dozens of joints and actuators, each requiring simultaneous transmission of high-current power (driving motors) and high-speed signals (encoder feedback, sensor data) — placing extreme demands on connector integration and vibration resistance.
The traditional approach of routing power and signal cables separately consumed significant internal space, with complex wiring harnesses increasing assembly difficulty and failure rates. The OEM's engineering team found a customized high-current connector solution that integrates power and signal transmission within a single connector — nearly 50% smaller than conventional solutions while delivering up to 150A of current-carrying capacity within a limited footprint.
"Every cubic centimeter inside a robot is more valuable than gold. This high-current connector freed up precious space for more functional modules," said the OEM's R&D director. The new solution also supports magnetic blind-mating functionality, allowing robots to automatically align and connect at charging stations without human intervention. The humanoid robot product has attracted significant market attention since launch, with its compact and efficient internal connection design becoming a key selling point.
Data Center OEM: The "Power Arteries" of the AI Computing Era
A data center infrastructure OEM is designing the next-generation power distribution solution for an AI computing cluster for a top-tier cloud service provider. Per-rack power density has skyrocketed from the traditional 5-10kW to 30-50kW — meaning power distribution boxes and connectors must carry unprecedented current densities within extremely limited space.
The OEM's core challenge: traditional internal connections in power distribution boxes cannot meet high-density deployment requirements — standard industrial plugs like IEC60309 are too bulky to fit in compact racks. Engineers found the DL28 series high-current connector as the solution. This connector is nearly 50% smaller than standard industrial plugs while delivering higher current-carrying capacity in the same footprint — perfectly matching the design requirements of high-density power distribution boxes.
"Every U of space in an AI compute rack is invaluable. High-current connectors let us pack more computing power into the same rack space," said the OEM's design lead. With the new solution, distribution box volume was reduced by 30%, internal wiring became cleaner and more organized, and thermal performance improved significantly. The solution has been adopted by multiple hyperscale data centers, becoming the new standard for AI computing power distribution connections.
