Automotive Crimp & Pin Connectors Market Technology Demand Analysis

Crimping connector technology provides highly reliable, cost-effective connection for automotive applications in harsh environments. It is a commonly used interconnection technology in the automotive market. Therefore, it is necessary to ensure that the crimping quality of the connector meets the requirements, and the quality of the pin pins of the connector is also very critical. The following is an analysis of the market technical demand of automotive crimping pin connectors shared by Huichengyuan connector manufacturers! As the electronic content in today's automobiles increases in complexity, driven by the frenetic pace of technological advancement, so does the need for innovative interconnect solutions for printed circuit boards (PCBs) and electronic module assembly processes. Over the past decade, solderless termination connections have been at the forefront by providing ultra-reliable cold solder connections to PCBs by creating continuous, airtight interfaces even in the harshest automotive and transportation environments.

Central to the technology's continued success is eye-of-the-needle (EoN) crimping or compatible stitch geometries, AVX Interconnect first patented computer and telecommunications backplanes in the 1970s, and the EoN-compliant section stamping and stamping process has been refined several times to ensure that the combination of material types and geometries continues to meet changing automotive requirements, such as increasing contact sizes, current ratings and temperatures. Although the original patent has expired and other connector manufacturers can take advantage of the underlying EoN technology, routine modifications to the initial design continue to deliver maximum EoN performance, delivering high and constant forces through double reverse beams in extreme heat, commonly used in impact and vibration applications. Because of the elimination of soldering processes for crimp interconnects, the relatively large connectors and custom modules commonly used in automotive applications are no longer exposed to the high soldering temperatures inevitable when using most other competing connector technologies, especially lead-free soldering processes, and can be produced using more cost-effective plastic materials. The crimp zone of EoN-compatible connector pin-pin interconnect technology is designed to be resilient enough to deform during insertion, and this ductility prevents damage to the plated through-hole (PTH) while also significantly reducing any applied stresses that can jeopardize the long-term reliability of the connection, including common solder defects such as cold solder joints, bridging, and improper wetting. The automotive module assembly process is unique in that the PCB can be pressed directly into the module, thereby securing EoN pins from the stitching or insert molding process. This provides an extremely simple, cost-effective and consistent assembly technique that can even reduce additional connector components and assembly time. Crimp connector technology The pin-pin geometry capable of withstanding harsh automotive environments is some of the earliest and most significant advancements, also at the expense of replacing individual pins in early high-cost telecom backplanes. However, the current automotive market requires permanent connections that combine mechanical and electrical components in connector pin-to-board interfaces, providing a one-time connection that does not weaken over time and temperature like traditional solder joints. This feature is the source of the dual name of the technology. "Crimping" refers to the termination process, and "compatible pins" are the expected level of performance of the guide pins when subjected to extreme temperatures such as thermal shock and vibration. Another unique feature of the Automotive Crimp Pin Connector market is the demand for power and high reliability in harsh environments of extreme temperatures, shocks, and vibrations. These functions are achieved through a combination of material thickness and type. The reliability of these connections is due to the versatility of tin plating on the connector pin pins and the PCB (as a result of the dip plating process), with the help of the press-in process, a metal bonding component is formed between the two. Thanks to the combination of these matched base materials and optimized pin geometries, it is now possible to achieve durability of + 170 °C for engine-mounted sensors, or to require current carrying capacity of 20A (or higher) in complex electromechanical power steering or electric vehicle modules. Crimp connector technology plays a crucial role in the high reliability performance of every automotive system being developed today, from advanced driver assistance systems (ADAS) to passive and active safety systems, transmission and gear controls, and even dashboard and comfort systems.Regardless of the application, pin crimp-compliant connector pins provide automotive system designers with the ultimate solderless connection solution.
