Type-C 16P 7.35 Front-Attached, Rear-Inserted with Elastic Band

The Type-C 16P 7.35 front-attached, rear-inserted with elastic band connector is a 16-pin USB Type-C receptacle featuring a 7.35 mm shell length and a hybrid front-SMT, rear-DIP termination design, enhanced by built-in elastic contact bands (spring fingers) on the shell. It combines compact dimensions with reinforced retention and stable electrical contact.

Design and Construction

This connector is a 16-pin USB Type-C female receptacle designed for horizontal (right-angle) board mounting. The 7.35 mm shell length is a widely used mid-length specification that balances board-space savings with mechanical strength.

The front-attached, rear-inserted architecture merges two termination methods. The front contact pins are surface-mounted (SMT) directly to the PCB, while the rear mounting legs pass through the board (DIP/through-hole) for strong anchoring against insertion and extraction forces. This hybrid approach delivers the space efficiency of SMT with the mechanical robustness of through-hole mounting.

The elastic band feature refers to spring-loaded metal fingers integrated into the connector shell. These elastic bands serve two primary functions. First, they increase mating retention by exerting outward pressure against the mating plug, preventing the cable from loosening or accidentally disconnecting during use. Second, the spring fingers suppress electromagnetic interference (EMI) and improve grounding stability by maintaining consistent shell-to-shell contact.

Applications

The 7.35 mm length with front-rear hybrid mounting and elastic band retention is well suited to power banks, charging docks, smartphones, tablets, portable speakers, and compact consumer electronics. The elastic band design is particularly valuable in applications subject to frequent plugging, vibration, or movement, where cable retention and stable contact are critical. The 16-pin configuration provides essential power and data connectivity with a smaller footprint than 24-pin variants, making it ideal for space-constrained designs that do not require full USB 3.2 high-speed data capability.
