Description
This 2.0mm pitch 2×20P high latch box header, commonly known as cow horn box header, is a high-reliability right-angle PCB connector professionally designed for board-to-cable connection in various electronic and industrial equipment. Different from ordinary simple box headers without locking structure, this upgraded box header adopts an integrated plastic side high latch design, which delivers stable locking performance and effectively prevents accidental disconnection between the box header and matching IDC receptacle during long-term equipment operation, vibration, and frequent plugging and unplugging processes. It is a core connecting component optimized for high-stability and high-safety electronic wiring scenarios.
Manufactured with premium 9T engineering plastic housing, this box header features excellent mechanical toughness, outstanding dimensional stability, and superior heat resistance, fully adapting to standard wave soldering production processes and long-term complex operating environments of electronic equipment. The overall height of the plastic with integrated side latch reaches 21mm, adopting a professional high-ear structural design. The high latch structure enhances the locking stroke and clamping force with the mating IDC female socket, realizing ultra-firm assembly connection, which is especially suitable for equipment that requires anti-loosening and anti-drop connection performance.
This double-row 2×20P box header is equipped with dual-specification pin lengths of 9.5mm and 13.5mm, supporting diverse PCB assembly and wiring layout requirements. Adopting a standard regular right-angle bending process, the 90-degree bent pin structure enables parallel mounting on the edge of the PCB board, greatly saving vertical space inside electronic equipment and realizing compact and standardized circuit board wiring. The double-row 2×20P pin layout provides up to 40 effective signal transmission channels, which can meet the multi-channel signal and low-power synchronous transmission needs of complex electronic control systems.
All conductive contact pins of the connector are plated with 0.8μm thick pure gold, a high-standard surface treatment process for precision electronic connectors. The 0.8μ gold plating layer completely covers the contact area of the pins, effectively isolating air and humid moisture, preventing metal oxidation and rusting of the terminals. It maintains ultra-low and stable contact resistance for a long time, avoids signal attenuation, intermittent connection, and poor conduction failure caused by terminal oxidation, and ensures high-precision and high-stability signal transmission. Compared with tin-plated connectors, gold-plated products have far better electrical conductivity, corrosion resistance and service life, suitable for long-term uninterrupted operating equipment.
This cow horn box header has passed the strict 48-hour salt spray test, verifying excellent anti-corrosion and anti-rust performance. It can stably work in high-humidity, coastal, slightly corrosive and harsh industrial environments, effectively resisting electrochemical corrosion and environmental oxidation, greatly reducing product failure rate caused by environmental factors, and extending the overall service life of electronic equipment wiring systems.
The 9T plastic material selected for the housing is a customized high-performance engineering plastic for connectors, with high rigidity, strong impact resistance, not easy to crack or deform during assembly and use. The integrated one-piece molding process of the plastic main body and side latch ensures no loose structure or broken parts after long-term plugging and vibration, with excellent structural durability. The right-angle bending process adopts standardized industrial production, with smooth pin bending, uniform force, no internal metal damage, and consistent product batch stability.
In terms of production quality control, every finished 2.0mm 2×20P high ear box header undergoes full-range quality inspection before delivery, including appearance inspection, dimensional tolerance detection, pin flatness test, conductivity detection, salt spray aging test and plugging life test. We strictly control every production process and dimensional parameter to ensure that all products fully comply with customer drawing standards and industrial specifications. Meanwhile, we support personalized customized services, including pin length adjustment, plating thickness modification, pin position optimization, special structural customization and customized packaging solutions, to meet the differentiated needs of different electronic projects and equipment applications.
As a high-performance locked box header connector, this product perfectly matches the 2.0mm pitch IDC female receptacle and supporting wiring harness. It is widely used for internal board-to-cable fixed connection and signal transmission of various electronic devices. Relying on its anti-drop locking structure, stable electrical performance, excellent environmental resistance and cost-effective industrial design, it has become the preferred connecting component for medium and high-end electronic control equipment, effectively solving the problems of easy loosening, poor contact and short service life of ordinary connectors in complex working environments.
