Teach you what to pay attention to when buying sockets?
The socket is also called the power socket and the switch socket. The socket refers to a seat that can be inserted in one or more circuit wiring, which can be inserted into various wiring through it. This is convenient to connect with other circuits. Through the connection and disconnection between the line and the copper parts, the connection and disconnection of the circuit will be reached in the end.
1. Selection channel
Consumers should not be cheap when buying power sockets. It is best to buy business places such as regular large chain supermarkets, hypermarkets or electrical cities, and retain shopping vouchers.
2. Look at the appearance
The style and color of the switch should be consistent with the overall style of the indoor. For example, the overall color of the interior decoration is light, and dark switches such as black and brown should not be used. And the manufacturer and product information of the qualified sockets are complete, and some unqualified sockets are rude. The most basic manufacturers and product information, especially the production date on the product packaging. This often belongs to unqualified sockets. In addition, the qualified socket shell panel is finely worked, there is no burrs on the shell and jacks, symmetrically uniformly in size of the jack, and the workmanship with poor mass socket shells is rough.
Third, look at the feel
It can be identified from the four aspects of the weight, repeatedly according to the switch, the trial insertion force, and the power line:
1) Type weight: There are many copper wires, thick copper sheets, and strict plastic shells in the interior of the sockets that meet the national standards.
2) Repeatedly press the switch: you can repeat the socket switch several times, the qualified socket is freely opened and the sound is crisp; the unqualified socket feels hard and easy to stagnate.
3) Test plug -in force: The qualified socket not only has a moderate elasticity of the insertion feel of each hole, but also the consistency of the insertion of each jack; Each hole can obviously feel different feel.
4) Power -pulling source: The power line of the qualified socket is soft and hard, and the connection with the socket is solid and reliable; the power cord feel of the unqualified socket is soft, the connection with the socket is not firm, and it is easy to pull off.
Fourth, look at the brand
Encourage everyone to choose well -known brands. Because the quality of the switch is related to the normal use of electrical appliances, and even the convenience of life. In the interview, many dealers have expressed the same view, that is, the switch or socket produced by many small manufacturers is unreliable, and it does not take long at all, and it is obviously very troublesome to replace it.
5. Look at the service
Go to the specialty store or sales point designated by the regular manufacturer as much as possible, and ask for shopping invoices, so as to ensure that you can enjoy future after -sales service.
