What Is The Difference Between Heavy-duty Connectors, Metal Connectors And Plastic Connectors?

What is the difference between Connector Hood/Housing and plastic connectors?

Features: antifreeze and cold resistance, environmental protection, waterproof, and UV protection. The number of cores can be selected: two cores, three cores, four cores, five cores, six cores, seven cores, eight cores, nine cores, etc.
Products are used in: LED guardrail tubes, LED display screens, outdoor lamps, solar lamps, landscape projects, aquariums, beauty and medical equipment, leisure and entertainment equipment, intelligent instruments and equipment, communication audio-visual equipment, sanitary ware and other industries and fields.
Molding method: Sockets and plugs are stamped and then injected into one piece, widely used in LED outdoor lighting waterproof plugs, connectors, and power cord plugs.
Product advantages: At present, LED outdoor waterproof male and female plugs, waterproof wires, waterproof power cords, waterproof connecting wires, waterproof plug wires, etc. have been widely used in society, mainly waterproof male and female plugs, waterproof wires, waterproof power cords, and waterproof plug wires. These products have the advantages of environmental protection and energy saving, and can play the role of UV protection, radiation protection, anti-oxidation, and anti-aging in the hot summer. The waterproof wire plays the role of moisture-proof, moisture-proof, and cold-resistant in the cold winter. Male and female head connection method: first put on the silicone ring, and then the male and female ends are plugged in and the nuts are locked.
The connector of the waterproof line is a new type of waterproof connector that can operate well in various environments such as high temperature, high humidity, high vibration and high impact, while the plastic connector does not have these characteristics.
1. Mechanical life: The mechanical life of the waterproof line refers to the number of insertion and removal life, and the industry standard usually stipulates that it is 500 to 1000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the waterproof line should not exceed the specified standard value, which is not much different from the plastic shell.
2. Electrical performance: The rated voltage, rated current, contact resistance, insulation resistance, etc. are according to the specified standard values, and this metal is the same as the plastic shell.
3. Environmental parameters: Environmental parameters mainly include ambient temperature, humidity, temperature change, atmospheric pressure and corrosive environment. The environment in which the waterproof line is used during storage and transportation has a significant impact on its performance. Therefore, the corresponding metal shell is selected according to the actual environmental conditions.
4. Termination method: The termination method refers to the connection method of the male and female connectors of the waterproof connector and the hardware contact part of the wire and cable. The metal is the same as the plastic shell. Comprehensive analysis shows that, except for the need for shielded connectors, there is little difference in performance between metal and nylon TA66 plastic housings. Plastic is cheaper than metal housings and has a more reasonable structure.
