That s what that black socket plugs in?

Black slot, PCIe interface.

In terms of electrical specifications, there is no difference between the black interface and the independent graphics card slot next to it, both are PCIe slots.

The difference between the two is the amount of data bandwidth that can be used.

The black slot is PCIe 1x bandwidth, while the discrete graphics card is PCIe 16x or 8x bandwidth.

This type of slot is generally used to install other expansion cards, such as sound cards.

Nowadays some network cards are of this kind of small slot. The new motherboard is basically this slot. The white groove is gone.

The computer visually inspected the Dell XPS series, and the three interfaces behind it are all audio interfaces, which are not universal, and only plug in the leftmost green interface when used at ordinary times.

The specific differences are as follows:

Green port on the far left: audio output port. It is mainly used to connect headphones or speakers, generally or channels.

Middle black connector: rear surround speaker connector. It is mainly used to connect to the rear surround sound, 4 8 channels are dedicated, and it is basically not used.

Orange connector on the far right: Mid-mounted subwoofer connector. Not even more so.

The black socket is the PCIe interface, which can be used to connect to the PCIe WiFi network card or PCIe graphics card.

You can look it up in the manual or ask it in the special after-sales maintenance.

The socket shell is a common electrical appliance in our lives, which is used to protect the wires and plugs inside the socket from electric shock accidents. However, why is the inside of the socket housing black?

The reason for the black color.

The reason why the inside of the socket housing is black is to prevent electromagnetic interference. We know that electromagnetic waves travel through the air and have an impact on both the human body and devices. This is a very serious problem for some places that are particularly sensitive to electromagnetic waves or require electronic equipment to work stably.

The black shell can effectively prevent the occurrence of electromagnetic interference, because black is a good color that absorbs electromagnetic waves. If the plug-in holder shell is not black, it may affect the operation of the device and even cause damage to the device.

The material of the socket housing.

The materials of the socket housing are usually plastic and metal. Depending on the material, the performance of the socket will vary.

The plastic shell of the socket is relatively lightweight, and the verification ** is also relatively cheap. For some ordinary household use, this is a more reasonable choice. Metal-encased receptacles are often used in more demanding locations, such as industrial production environments and medical settings.

The socket with metal shell has high wear resistance and anti-corrosion, which is more stable and reliable in long-term use.

Safety issues in the use of outlets.

Even though the inside of the socket housing is black, its safety needs to be taken very seriously. When using the socket, pay attention to the following:

Avoid pulling and pulling the plug indiscriminately, so as not to cause loose or short circuit of the line.

Avoid using the socket in a humid or dusty environment.

Avoid injecting metal or liquid into the socket to avoid causing a short circuit or electric shock.

Regularly check the performance of the socket and replace it in time if there is a problem.

Only by using and maintaining electrical equipment correctly can we better protect our own lives and the lives of others.

Conclusion The reason why the inside of the socket housing is black is to prevent electromagnetic interference. The material and safety of the socket are also issues that need to be paid attention to when using electrical equipment in our lives. Only by learning to use the socket correctly and paying attention to the safety of the socket can we ensure the proper operation of electrical equipment and at the same time keep ourselves and our families safe.

Summary. The blackening of the plug may be due to the following reasons: the plug itself is inferior, it is an inferior product, the copper sheet is very thin, and the resistance is very large, which causes the resistance to become larger due to heating after contact with the socket during use, and the plug oxidizes more severely.

Hello! I'm glad to answer your questions! Reply to your tenant within 5 minutes (we are all manual replies).

The blackening of the plug may be due to the following reasons: the plug itself is inferior, it is an inferior product, the copper sheet is very thin, and the resistance is very large, resulting in the resistance becoming larger due to heating after contacting the socket when it is used early, and the oxidation of the plug is more serious.

2.The electrical appliance connected to the plug is too powerful, and the copper piece does not match it, just like a small horse-drawn cart, which is definitely not suitable. 3.

The plug does not match the size of the hole in the socket hood. When the size is not suitable, it is easy to ignite. When the ignition phenomenon occurs, the temperature of the plug and socket rises sharply, not only the oxidation of the head, but also the plastic insulation of the socket will also be blackened due to the temperature.
