If we want to use waterproof DC socket, we will choose a good quality waterproof DC socket. How do we choose it? The following is a detailed introduction to the choice of methods.
How to choose a waterproof DC outlet
One, Dongguan waterproof DC socket marking judgment
Marking is an important basis for people to correctly install, use and maintain, and is an extremely important safety standard for ensuring the safety of personal property. Plug and socket products should be marked with rated current, rated voltage, power supply and so on. In addition, the converter (the converter refers to a mobile electrical attachment with only one plug part and one or more socket parts combined) to mark the rated current / or power with the "MAX (or maximum)" symbol to guide the user to avoid overloading.
Signs or symbols should be durable, clear and discernible. It is not to be used to easily erasable silk and paper marks; the rating is the most basic electrical interchangeability parameter that ensures the normal, safe and cooperative use of the plug and socket, the converter and the connected electrical appliances. For example, the rated current of the converter shall not exceed the rated value of the plug part. Otherwise, it may cause the user to be in danger of overcurrent heating when the electrical appliance is selected according to the rated current of the socket. The minimum rating of the converter with the fuse and overload protector should be equal to the rating of the fuse and the overload protector. Otherwise, there may be damage to the product.
Two, Dongguan waterproof DC socket size selection
Size is an important technical requirement that is related to the safe use of waterproof DC sockets and converters and whether to meet the general interchangeability requirements in order to avoid incorrect insertion. The disqualification of the size will affect the user to use or produce the hidden trouble of contact, misuse and other hidden dangers, the light makes the equipment damaged, the weight will cause the fire and the electric shock accident; the anti shock protection is to ensure the plug and socket, the converter under normal use, and even some unexpected circumstances, it will not cause the electric shock accident of the user and others. A key safety indicator. When the plug and socket are fully or partially plugged in, the charged part of the plug should not be touched, and any plug pin should not be intercalated with the plug socket when the other pins are in touch. Plugs, sockets and converters with protective doors should prevent monopole or probe insertion.
Three, Dongguan waterproof DC socket socket module standard
The insert assembly should be flexible enough to ensure sufficient contact pressure on the plug and plug. The plug should be corrosion-resistant and wear-resistant to ensure good contact between plugs and sockets; plug pins should be locked and not rotated, otherwise the insertion performance and unsafe factors will be affected; the converter has a soft wire fixer to ensure that the soft wire is fixed, can withstand normal tension and torque, plugs and sockets are inserted. At the same time, the plugging surface should be basically strict to prevent electric shock.
High temperature has great influence on all kinds of properties of insulation material. The structure and characteristics of insulation material will change essentially in high temperature. This change determines the reliability of material use. Some materials will gradually soften in high temperature and decrease the mechanical strength. This will affect the quality of plug socket and the safety in use. In addition, the insulation materials of plugs and sockets should have certain flame retardancy. Otherwise, if the product is on fire in use, it will become unmanageable. Understand the safety performance of plugs and sockets, grasp the above points when buying and using, and minimize the risk factor.
