Cee connectors are usually used in water environment. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. The performance of the connector ensures that the internal mechanical and electrical performance of the connector can be used normally under water pressure. If the product has good performance and the product must meet the standard performance conditions, then what conditions?The following explains some numbers in cee connector to prevent dust.0 means there is no protection, no special protection against people or things outside;The number 1 indicates that it can prevent the intrusion of 50mm solid objects, effectively prevent the human body or palm from accidentally touching the accessories and equipment inside the electrical appliance, and prevent the intrusion of 50mm objects;The number 2 indicates that it can prevent the intrusion of 12mm objects, prevent people or palms from accidentally contacting accessories and equipment in electrical appliances, and prevent the intrusion of 12mm objects;The number 3 indicates that it can prevent 2.5 mm solid objects from invading and 2.5 mm small external objects from contacting the inside of electrical appliances.The number 4 means to prevent 1.0 mm solid objects from invading, strictly control the smiling particles, and prevent 1.0 mm small external objects and internal parts of electrical appliances from coming into contact;The number 5 shows that it is dustproof, completely preventing foreign objects from invading, and the amount of invading dust will not have any influence on the normal operation of electrical appliances;Number 6 indicates that dust prevention completely prevents foreign matter from entering, which can completely prevent dust from entering, and is the highest excellent protection level.For the meaning of water droplets.0 means there is no protection.One is used to prevent water.2 indicates that dripping water can still be prevented from invading when inclined at 15 degrees.3. Prevent water from being sprayed on4 means to prevent splashing water from invading.5. Prevent water intrusion by hydraulic jet to avoid damage caused by hydraulic jet intrusion in all directions;6 indicates the intrusion of dust-proof waves, which will not cause damage to electrical appliances even if the waves invade and are installed on the deck;During flooding, even if the electrical appliances are immersed in water for a period of time or under a certain water pressure standard, they should be prevented from flooding to ensure that the electrical appliances will not be damaged by flooding.8 is to prevent water from sinking when invading, which is the highest level, and can make electrical appliances sink indefinitely under certain water pressure, without causing water damage to electrical appliances.
