Waterproof connector quality judgment method

When purchasing waterproof connectors, users should first compare the quality of waterproof connectors. It also has waterproof function, shell quality, production process, size structure, connection performance, price, delivery speed and so on, which are the problems that users should consider. The first thing to consider when choosing a waterproof connector is the waterproof performance of the product. Waterproofness usually depends on three aspects: 1. Size and structure: Waterproof connectors usually have IP68/IP67/IP66/IP65 waterproof rating. The smaller the size of the product, the more difficult it is to meet the requirements of waterproofing and connection, and the waterproofing grade is slightly lower. As far as the structure is concerned, pay attention to the position of vulnerable parts and whether the waterproof position is reasonable. Silicone gaskets, for example, cannot be exposed too much to prevent UV corrosion from affecting performance and longevity. 2. Shell material: Shell material shall be made of tough, heat-resistant, flame-retardant and corrosion-resistant materials, such as PA66; wire shall be made of elastic, flame-retardant, wear-resistant and wear-resistant materials, such as PVC or rubber. Manufacturing process: The connector product is comfortable, fine texture, not too slippery or too thick, no burrs in the workmanship, and it should feel natural and not slippery when connecting. Users can evaluate the production technology and strength of the manufacturer by on-the-spot investigation or on-site samples. The second key point is the connection capacity of the connector: 1. Pin: a good waterproof pin is usually pure copper. The pin will be gold-plated or nickel-plated to increase the permeability. Users should keep their eyes open when purchasing, so as to avoid manufacturers using hollow copper pins. 2. Copper wire: The material of copper wire is generally pure copper wire. Now the manufacturer processes the wire by itself to ensure the quality while controlling the cost.
