TYPE-C 16P7.35 front-mounted and rear-inserted

Type-C 16P 7.35 Front-Mounted and Rear-Inserted

The Type-C 16P 7.35 front-mounted and rear-inserted connector is a right-angle surface-mount USB Type-C receptacle characterized by its hybrid termination design and a 7.35 mm shell length. The "front-mounted and rear-inserted" designation describes a specific soldering configuration in which the front shell legs are surface-mounted (SMT) and the rear mounting legs are inserted through the PCB (DIP/through-hole).

Design and Construction

This connector is a 16-pin USB Type-C female receptacle designed for horizontal (right-angle) board mounting. The "7.35" refers to the total shell length of 7.35 mm, which is a standard mid-length specification in the industry, balancing board space savings with mechanical stability-13.

The front-mounted and rear-inserted architecture combines two termination methods:

• Front (SMT): The forward contact pins and front shell legs are soldered directly to the PCB surface using surface-mount technology.

• Rear (DIP/Through-Hole): The rear mounting legs pass through holes in the PCB, providing strong mechanical anchoring against insertion and extraction forces-5-14.

This hybrid design offers the space efficiency of SMT while retaining the mechanical robustness of through-hole mounting, making it suitable for applications where the connector may experience frequent plugging or vibration-17.

Applications

The 7.35 mm length with front-rear hybrid mounting is widely used in power banks, charging docks, smartphones, tablets, portable speakers, and compact consumer electronics-13. The front-mounted rear-inserted termination style is particularly valuable in high-vibration environments such as automotive electronics and industrial control equipment, where the through-hole rear legs prevent solder joint failure under mechanical stress-13-17. 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.
