Selection method of quality of waterproof connector

When purchasing waterproof connectors, users first need to compare Waterproof connector Quality of. In addition to the waterproof grade, shell quality, production process, size structure, connection performance, price, delivery speed, etc., these are the problems that users need to consider.

purchase Waterproof connector When, the first concern is the waterproof performance of the product. Waterproof performance is usually determined by three aspects:

1. Size structure:Waterproof connector The waterproof grade of is generally IP68 / IP67 / IP66 / IP65. The smaller the product size, the more difficult it is to meet the requirements for waterproof and connection, and the waterproof grade is slightly lower. In terms of structure, it is necessary to observe whether the position of easily damaged parts and waterproof position are reasonable. For example, do not expose too much silicone gasket to prevent ultraviolet corrosion from affecting performance and service life.

2. Shell material: the shell material shall be made of materials with strong toughness, temperature resistance, flame retardant and corrosion resistance, such as PA66; Wires shall be made of flexible, flame retardant, wear-resistant and corrosion-resistant materials, such as PVC or rubber.

3. Manufacturing process: the product feels comfortable and has texture. It shall not be too slippery or too thick. The workmanship shall not have burrs. It shall feel natural and not slippery when connecting the joint. Users can evaluate the manufacturer's production technology and strength through field investigation or samples.

The second focus is on the connection function:

1. Pin: OK Waterproof connector The pin is generally solid pure copper. The pin will be plated with gold or nickel to increase the conductivity. Users should polish their eyes when purchasing to prevent unscrupulous factory household hollow copper pins from making up for the number.

2. Copper wire: the material of copper wire is generally pure copper wire. Now powerful manufacturers deal with the wire themselves to control the cost and ensure the quality at the same time.
