We take a lot of technology for granted these days — the convenience of USB that we overlook is perhaps one of the best examples of this. The
Universal Serial Bus standard
In 1996, Intel launched USB technology with contributions from various partners including IBM, Microsoft, and Compaq. Prior to the advent of USB, connecting peripheral devices such as printers, storage units, and other computers typically involved using multiple types of connectors and wires.
Jump ahead a quarter-century, and almost every intelligent electronic device is fueled by USB technology — whether for charging or data transmission. Over this time, there have been
several generations of USB
Over time, the most advanced version has become the compact and reversible USB Type-C connector. Nonetheless, many people typically envision a large Type-A port when thinking about USB connections. Should you have examined such a cable before, you would have observed two small square openings on each side of the plug.
Although these features do not enable direct connectivity between a male and a female USB port, they play an essential role in providing stability through their built-in locking mechanisms. Similar to how the dual slots on electric plugs stop them from pulling out with slight pressure, this straightforward yet functional aspect within USB connectors often goes unnoticed. However, it significantly contributes to maintaining a robust connection, highlighting its importance despite its subtle nature.

Upon closer inspection, you’ll see two spring-loaded retaining clips that match up precisely with the two square openings on the USB connector. Once inserted, these clips latch onto the slots and lock securely. Even though some connectors may not produce a noticeable clicking sound, you can often tell when the USB cable is properly connected by feeling the connector seat firmly as you gently push it in.
When snapped into position, this locking system stops the linked gadget or cord from sliding out of the socket. It guarantees that removing a USB plug requires deliberate effort, so you can avoid interrupted data transfers due to unintentional disconnections.
If not for the locking mechanism in USB connectors, ensuring uninterrupted connectivity would depend entirely on gravity. While this might be feasible for PCs equipped with top-facing USB ports, it would become problematic with various port orientations. Additionally, this feature aids in proper alignment. As an inert locking system without movable components, it offers a cost-effective solution to enhance both the longevity and sturdiness of USB interfaces.
