Tại sao một số ổ cắm mạng có nắp đậy và một số bị kẹt?

Some RJ45 plugs have an exposed lock release clip, like this:

• Does it actually have a function besides being annoying?
• Can I take a suitable tool and simply cut it off without affecting the cable’s function?

From experience, those retention clips break off a lot on the first sort of cables – those are fine for cables that are well protected and/or going to be plugged in and forgotten, but the moment those clips bend the wrong way, they break, and you end up with a cable that dosen’t clip in place. They also snag each other sometimes and are just a PITA.

Cable boots (yes thats the proper name for them) keep cables from snagging, those clips from breaking, and generally ensure the cable dies from other things, like rabbit attacks, pruning shear accidents, and backhoe incidents. On the other hand, those cables are not slipping out from their sockets cause a tiny bit of plastic broke, and thats whats important.

Feel free to remove them, or get cables without them, but I personally find them pretty useful (and cables with them tend to be better made in many cases). They have no major structural or electrical purpose.

When retracting a RJ45 plug through narrow tubing or around corners, the clip tends to snap off, effectively making the network cable useless in most environments. The rubber dome (most commonly referred to as a cable boot) nearly always prevents that from happening.

You wouldn’t know how many network cables I’ve seen with broken off clips.
