In the use of DC plug prone to loosening the situation, how to avoid this situation, the specific steps are what? The following details are introduced to you.

DC plug is easy to loose in use, in fact, DC plug is not easy to loose, as long as it is inserted tightly, even scraping back and forth will not loose.
Then, how can we make DC plugs tightly attached to the artifact without loosening?
Standard procedure:
1. insert the DC plug into the DC socket.
2. force down the DC plug to press it tight.
3. rotate the DC plug to the left and fix it.
It is understood that, in addition to a very small number of enterprises after careful design and testing of products to meet the requirements, the vast majority of the multi-purpose sockets on the market are safe hidden dangers, how to choose safe products, become the issue of greatest concern to everyone, for this reason, experts suggest that consumers in the purchase of these products, should pay attention to The following points:
First, when purchasing mobile socket and converter products, should choose rated voltage, rated current and residential wall socket consistent with the size of the rated current, consumers should first pay attention to the size of the rated current, the order should be plug (> power line (> mobile socket or converter (> electrical appliances), the order must not be reversed Come, because if the electrical power is too high or the power line load capacity is not enough DC socket, can lead to heat accumulation and fire.
The other is that the plug and converter terminals for removable wires must be threaded clamped terminals (e.g. screw terminals), which are designed to prevent the power cord from being pulled out by unexpected pull-outs, and must have flexible wire fixing parts to enhance tensile resistance. Welding is permitted only if the plug and converter form an integral non-removable wire. Way.
Third, the plug type stipulated by the national standard is flat, with two poles and two poles grounded (commonly known as three poles) plugs, plugs that do not meet the standards or have been banned are: cylindrical plugs, plugs with holes on the plug, plugs that can be rotated plugs and earth pole plugs can be hidden plugs.
Fourth, special attention should be paid to plug, socket material, should pay attention to the selection of flame retardant plastic production socket, the higher the flame retardant level, the better, because if plug, socket material is not flame retardant, then in the case of short circuit, fire, overpressure, over-current will cause heat accumulation and cause fire, material selection should also pay attention to screening gold The socket should have good conductivity and plugging force, and its copper content should reach 50%. The earphone socket should also choose the elastic material (such as Tin Phosphorus bronze) as far as possible.
Fifth, carefully use multi-hole socket, if the design of multi-hole socket is improper, inadequate precision, it is very likely to occur in the use of electric shock accidents, will also lead to misinsertion, but also carefully check the protection door, to check whether the gap between the protection door is too large, because the gap is too large to really protect the user's body It's safe.
Sixthly, consumers need to have some basic identification skills. Starting with the appearance of the product, the rated current is clearly defined in the national standard. The plug socket is divided into single-phase detachable plugs: 10A and 16A, single-phase non-detachable plugs: 6A, 10A and 16A, single-phase sockets: 10A and 16A, such as 13A, 15A non-standard. Products are not allowed to be sold on the market, let alone marked with 10A, 16A, in addition, to check the product packaging manufacturer or supplier's address, telephone, etc. are complete, in addition, in the selection of plugs, sockets, products, should also pay attention to whether there is a national compulsory product certification mark, that is, "CCC" mark. As far as possible, we should purchase products of large and medium-sized enterprises as far as possible, and never pursue the low price unilaterally.
