Network Plug Covers: Why Some Have Them and Others Don't
The Purpose of Cable Plug Covers in Network Cabling
Observing network setups in office environments over time reveals a noticeable pattern regarding cabling. Certain cables feature a protective covering over the RJ45 connector, while others expose the connector directly.
Understanding the Function of the Plug Cover
The small plastic cover found on some network cable plugs serves a specific purpose. It's designed to protect the delicate contacts within the RJ45 connector.
These contacts are susceptible to damage from both physical impact and environmental factors. The cover acts as a shield against these potential issues.
Benefits of Using Cables with Plug Covers
- Reduced Damage: The cover minimizes the risk of bent or broken connector pins.
- Improved Reliability: Protecting the contacts ensures a more consistent and reliable network connection.
- Corrosion Prevention: The cover can help prevent corrosion of the metal contacts, especially in humid environments.
The question prompting this explanation originated from SuperUser, a segment of Stack Exchange—a collaborative network of question-and-answer websites.
Essentially, the presence or absence of a plug cover is a design choice impacting the cable’s durability and long-term performance. While not always essential, it offers a valuable layer of protection.
Understanding RJ45 Plug Design Variations
A SuperUser user, Michael Kjörling, has posed a question regarding the differing designs of RJ45 plugs.
Specifically, he notes some plugs feature an exposed lock release clip, while others conceal it beneath a rubber cover.
The Question of the Rubber Cover
Michael expresses frustration with the rubber covers, finding them largely inconvenient.
His inquiry centers around the purpose of these covers and whether they can be safely removed without compromising the cable’s functionality.
Functionality of the Rubber Cover
The rubber cover isn't merely an annoyance; it serves a distinct purpose.
It provides protection against accidental disconnections.
Preventing Accidental Disconnections
The lock release clip, when exposed, is susceptible to being inadvertently pressed.
This could lead to the cable becoming detached from the network connection.
The Protective Role of the Cover
By encasing the release clip, the rubber cover prevents unintentional activation.
This is particularly important in environments where cables are subject to movement or accidental contact.
Can the Cover Be Removed?
While it's understandable to want to remove the cover for ease of use, it’s generally not recommended.
Cutting or removing the cover could increase the risk of accidental disconnection, negating its protective function.
Considering the Consequences
Although a tool could be used to remove the cover, doing so introduces a potential point of failure.
The slight inconvenience of the cover is often preferable to the disruption caused by an unreliable connection.
Recommendation
Michael should consider leaving the rubber covers intact.
The benefits of maintaining a secure connection outweigh the minor inconvenience they may present.
Cable Clip Retention: An Examination
A SuperUser community member, Journeyman Geek, shares valuable observations regarding cable retention clips.
Based on practical experience, these clips are prone to breakage, particularly on the initial generation of cables. While adequate for cables that are well-protected or intended for permanent connections, they become vulnerable when subjected to bending. This results in cables that fail to securely latch into place.
Furthermore, these clips can sometimes interlock and create difficulties. Cable boots, the correct technical term, serve to prevent snagging, protect the clips from fracturing, and generally extend the cable's lifespan against external factors. These include damage from animals, accidental cuts, and even construction equipment.
Conversely, cables equipped with boots are less likely to disconnect due to minor plastic failures. Removing the clips or opting for cables without them is permissible, but they are often found on higher-quality cables and offer practical benefits. They do not contribute significantly to the cable’s structural integrity or electrical performance.
Another user, oKtoSite, reinforces the advantages of utilizing cable boots.
During the process of retracting an RJ45 connector through confined spaces or around bends, the clip is susceptible to snapping, rendering the network cable largely unusable in many settings. The rubber dome, commonly known as a cable boot, consistently mitigates this risk.
The prevalence of network cables with broken clips is surprisingly high.
Our own experience aligns with these perspectives. Cable boots are demonstrably useful, and their retention is generally recommended unless specific circumstances dictate otherwise.
