Introduction

BCS-142-L-D-TE-051 introduced by manufacturer Arcol is a two row, shielded, 2.54mm pitch, rectangular connector header. It is available with polarization options to ensure the normal operation of the assemble and supports the board to board connections through a latch and lock feature. This assembly features high contact current rating and extended service life; thus, they provide reliable performance even under vibration or harsh environment. Being a member of rectangular connector family, BCS-142-L-D-TE-051 offers unmatched reliability in headers, receptacles, female socket, and other categories. Furthermore, it is compliant with EU RoHS, UL and CSA regulatory standards and exhibits resistance to acid, alkali, oil, water, shock and vibration.

Headers

BCS-142-L-D-TE-051 headers consist of two rows of exactly spaced pins securely soldered in the same orientation on the printed circuit board. They are widely used in computers, DVD players, home entertainment systems, and industrial robotics.The conduction of electricity through the pins in the header is possible due to the wide acceptance and standardization of the popular .050 inch row pitch size. They allow connection to modules and daughter boards with receptacles or wired connections into walls or electrical wiring. These headers feature gold plated terminal pins to ensure good electrical contact and provide superior durability, robust structure, low insertion force, and fast operating cycle. They are also available with specialized, low torque contacts for PC boards.

Receptacles

BCS-142-L-D-TE-051 receptacles are compatible with headers that use CTA series contact in 2.54mm or 2.00mm pitch. It consists of a receptacle body which is molded from high-performance polycarbonate, and metal jackscrews are provided for the mounting to the PCB. Its multiple-contact design ensures reliable connections in electrically and mechanically tough environments. It is available in through-hole and surface mount packages with multiple circuit and termination options such as wire-to-wire and wire-to-board applications. By using receptacles based on state-of-the-art insulation displacement contact, BCS-142-L-D-TE-051 receptacles provide increased current capabilities with a lower force-to-mate. Besides, they also offer higher resistance to shock and vibration.

Female Sockets

BCS-142-L-D-TE-051 female sockets are used in applications ranging from stationary to portable and even wireless. It is available with precision manufactured, dual beam contacts for higher voltage and amperage performance. It features robust molded housings for reliable contact and strain relief with superior environmental protection for extended service life. It also offers greater control of performance through the utilization of mounting holes for PCB control. These sockets are designed and tested for high-speed data transmission applications such as USB 3.1, HDMI, DisplayPort, SATA, and others. Its electrical and mechanical design guarantees reliable connections under shock and vibration conditions, preventing the transmission of reduced data.

Working Principle

Each terminal pin in the BCS-142-L-D-TE-051 header, receptacle, and female socket has a plug hole for vacuum soldering to ensure a reliable electrical connection. This is accomplished by the hot gas produced from the vacuum soldering machine entering through the plug hole and causing an air pressure change. This change in air pressure pushes the pin against the printed circuit board thus lifting and holding the connection in place. The pin, once securely held to the board, is heated with a pre-determined temperature until the molten solder wets the contact surface and the electrical connection is ensured. This process is repeated with all the other pins to reach higher quality connections as compared with the manual soldering process.

Conclusion

BCS-142-L-D-TE-051 is a two row, shielded, 2.54mm pitch rectangular connector that offers reliable electrical connections in headers, receptacles, and female sockets. Through its polarization options and latch and lock features, it provides reliable performance even under vibration or harsh environments. Moreover, it is compliant with EU RoHS, UL and CSA regulatory standards and exhibits resistance to acid, alkali, oil, water, shock and vibration. By using vacuum soldering for a reliable electrical connection, BCS-142-L-D-TE-051 ensures a secure, robust, and long-lasting performance.
