Teach you how to easily select a circular connector

In a wet cold natural environment or in a liquid, the circular connector aviation plug socket is often subjected to dripping, spraying or intrusion of the liquid, so the introduction of a waterproof level can reasonably prevent the problems. Generally, people can use iP coding to express the waterproof rating of circular connectors, that is, IPx (where x is a large number from 0 to 8, the greater the higher the waterproof rating), as follows.
Waterproof rating of circular connectors: when x = 0-no maintenance on water. When x = 1-Avoid drops of water. When x = 2-When the circular connector case is skewed to a 16 degree angle, water droplets drip into the case without harm. When x = 3-precipitation, etc. from a 65 degree corner onto the cabinet or water sprayed, the RF connector is not harmed. When x = 4-liquid splashes on the RF connector housing from any direction and all angles without harm. When x = 5-tap water cleaning without any damage.

When x = 6-It can prevent the powerful gushing water (such as the sea surface) from entering and can be used for the natural environment in the cabin. When x = 7-can be used to avoid short-term immersion of water into the whole process. When x = 8-continuous immersion under the necessary working pressure can avoid the water from entering the aviation plug connector during the complete and continuous flooding.
Pay special attention to the following points when choosing a circular connector aviation plug socket:
Don't underestimate the circular connector aviation plug socket. Their quality is related to the safety of household appliances and the safety of people. Expert opinion: pay special attention to the following points when purchasing circular connectors for aviation plugs and sockets:
① Pay special attention to well-known brands and purchase goods from large, medium and small enterprises. This kind of company earnestly implements the national norms and the product quality is close.
② Pay special attention to the sign. The product must have a "CCEE" safety certification certificate. The product must have the manufacturer's company name, detailed address, and telephone number. The rated voltage requirements in national industry standards are divided into 6A, 12A, and 18A levels. , If there is no other marked level is a non-standard product.
③ Pay particular attention to "pairing", and select products that match the rated current and voltage with socket switches commonly used in housing. The order of the rated voltage from high to low should be power plugs, power plugs, portable power sockets, and power-consuming appliances.

④ Pay special attention to the power plug. The form of power plug required by the national industry standards in our country is flat, there are secondary and secondary power plugs with grounding device; cylindrical power plugs are obsolete products, and you don't need to buy them.
