Socket purchase knowledge

The socket involves the reasonable design of the electrical plug and the safety of the power consumption. This article briefly introduces the classification of the socket.

First, common size types.

Type 86: 86mm*86mm

Type 118: 118mm*74mm

Type 120: 120mm*74mm

Among them, the 86 -type socket is the most common style, four or four squares, although there are fewer sockets, it is safer and convenient for replacement. The main type 86 is divided into the following:

There are fewer types of 118 and 120 sockets. Most of them are multi -functional plugs. For small -power electrical appliances such as chargers, table lamps, etc., but if electrical appliances with large types of electrical appliances, such sockets will bring with electrical appliances, this socket will bring with electrical appliances. To use the potential safety hazards, it is easy to cause the contact point to heat or even burn the socket plug.

With the user -friendly improvement of the industrial design level, the largest purchase volume is this misplaced five -hole socket. Although for some friends with obsessive -compulsive disorder, it may be unaccustomed to it, but in fact, it is the most convenient to use Essence

And next to the bedside, sofa, and desk, you can choose a socket with a USB jack, so that it is more convenient to use a mobile phone. Of course, it should be noted that this plug uses 5V/3.1A output. And fast charge is not expected.


The kitchen is recommended for sockets with switches to avoid repeated troubles. The home appliances that are suspended by wall -mounted air conditioners and electric water heaters with large power consumption are special 16A three -hole sockets. Of course, it can bring switches better.

2. How to distinguish the quality of the socket based on the material?

Mainly look at the following points:

1. Material;

The currently recommended socket panels are made of PC and ABS; PC materials have good fire prevention flame retardant, which is safer to use. Generally, it is commonly used on high -end sockets, while ABS materials are slightly worse.

2. Loading;


The load is a contact component when plugging and plugging. The material of this component when purchasing is the focus of attention. It requires the material to resist, stable, and elasticity. The choice of material follows the phosphorus alloy

Copper zinc alloy (brass)

The order of copper alloy. View the carrier material can directly view the official website introduction, and you can pay attention to the workmanship of the internal components. If it is thickened and increased, there is a larger cross -sectional area, which means that it has better stability and conductivity, and more durable. Essence


3. Wiring terminal;

The wiring terminal behind the socket is one principle, and most of them are good. It can support more wires to achieve multi -share and connect more practicality.

4. Fixed frame;

There are generally two types of steel and PC materials. The strength of the steel is high but the wall surface and wiring are also high. The toughness of the PC material is easy to take off.

5. Protect the door;

Prevent children from playing with the jack to prevent children from playing with electric shock. As long as the plugs are inserted together to insert and can obviously feel the resistance, there is a protective door. Now the general brand socket has a protective door design.

6, 3C certification;

Whether it is a brand or other manufacturers, 3C certification is necessary, which is related to electricity safety.

Third, brand



Siemens, Schneider, ABB, Panasonic, etc. Things are good, but there is a disadvantage that is “expensive.”


Bulls, Delixi, Zhengtai, Op. Domestic brands will be cheaper and more economical.
