What Is a Connector Cover?
A connector cover is an accessory used to protect the plug portion of a cable (male connector) and improve safety.
In addition to preventing the intrusion of foreign objects, they are also useful in terms of security by preventing accidental insertion and electrical contact. It is shaped for easy attachment and removal according to the shape of each connector.
The most common materials used are plastic-based ABS resin and polyethylene. A similar component is the connector cap.
Uses of Connector Covers
Connector covers are used to prevent incorrect insertion, protect connector terminals, and provide security.
1. Prevention of Foreign Object Intrusion
Connector covers cover the plug to prevent foreign objects such as dust and moisture from entering the connector.
2. Prevention of Incorrect Insertion
Connector covers designed in specific shapes and colors prevent accidental insertion into the wrong connector.
3. Prevention of Incorrect Wiring
Combining several connector covers of different colors can prevent incorrect wiring.
4. Security Measures
Connector covers with a lock function prevents unauthorized access and data leakage.
5. Cable Disconnection Prevention
Fixing the connector part reduces the ease of cable disconnection and improves the stability of the connection.
6. Stress Reduction
The connector cover reduces stress on the connection between the cable and connector, contributing to longer service life.
Structure of Connector Covers
Some connector covers have special shapes. For example, a type with a curved brim side creates a gap between the connector and the brim, making it easier to pull out the USB connector. Also, caps with wide brims make it difficult to see the metal surface of the connector.
Some USB connector covers have a feature that locks when inserted into the USB connector. This lock can only be released when a special extraction tool is used. This feature further reduces the risk of incorrect insertion or unauthorized access.
Types of Connector Covers
There are various types of connector covers, depending on the device and interface. The following are examples:
- For PC cables
- For PDA cables
- For USB cables such as Type A, B, Mini-B, Micro-B, and C
- For cable connectors of digital video equipment, such as VGA, DVI, HDMI, etc.
- For network LAN and telephone modular jack cables
- For audio and video equipment cables

Difference From a Connector Cap
Connector covers are used to protect the plug portion (male connector) of a cable. On the other hand, connector caps are used to protect the female connectors on the equipment.
However, since they are often referred to without distinction, it is necessary to note which component is being addressed in context in writing and conversation.
