Many people are not clear about the selection of headphone sockets. To do a good job in seven aspects, the selection of headphone sockets is very critical, so in order to control the cost, we must start from seven aspects. Here are the details
I. Looking at the Appearance
The style and grade of headphone socket should be consistent with the overall indoor style. White headphone sockets are the mainstream, and the overall tone of most household appliances is light. In most cases, black and black headphone sockets should not be used.
2. Feeling by hand
Most of the high-quality headphone sockets are made of high-grade engineering plastics such as bullet-proof glue (PC). Fire-proof performance (flame retardant), moisture-proof performance, anti-collision performance, anti-ultraviolet resistance, etc. They have good surface texture. When choosing and purchasing, they should consider the feel of their own hands. The material of headphone sockets should be judged preliminarily by the sense of their hands. Generally speaking, the products with rough surface and thin and crisp feel can not be trusted. A good headphone socket panel requires no bubbles, scratches and stains. The socket of the headphone socket feels light but not tight.
3. Weighting
When purchasing a headphone socket, you should also weigh the weight of a single headphone socket. High-end headphone sockets should have enough weight, high-end products generally do not cut corners, light weight products must be suspected of cutting corners, should be cautious when choosing, because only the thickness of copper in the headphone socket, the weight of a single headphone socket will be heavy, and the copper in the socket is the most critical part of the headphone socket, if it is alloy or thin copper will not. It has the same weight and quality.
IV. Look at the logo
Attention should be paid to the necessary identification on the base of headphone socket and socket, such as national compulsory product certification, rated current and voltage value, product type, wiring identification and so on.
V. Look at Packaging
Product packaging should be standardized and complete, and the design and printing are exquisite. There should be clear trademark, manufacturer's address, telephone, company's website and other information, including instructions and certificates of use, attachment screw, etc.
6. Selecting Brand Manufacturers
It is better to choose products from regular and professional manufacturers. Because the quality of headphone socket is related to the normal use of electrical appliances, and even the convenience of life. Many small manufacturers produce unreliable headphone sockets, it takes not long, and frequent replacement is obviously very troublesome, so when choosing products, we should choose the products of regular and professional manufacturers. Regular products will generally make effective commitments to consumers, such as "guarantee 12 years of service life", "10,000 consecutive headphone sockets" and so on.
VII. SERVICE SELECTION
As far as possible to the regular manufacturers designated monopoly stores or outlets to buy, and retain shopping vouchers, so as to ensure that they can enjoy the future after-sales service.
The above is the selection method of earphone socket, these seven points can learn well, only when choosing and buying.
