As the name implies, 3 Pin Waterproof Cable Connector can be applied to the water environment, providing a safe and reliable connector, the most important of which is to achieve waterproof effect. Then how to choose the 3 Pin Waterproof Cable Connector? Which items should I pay attention to in the process of installation and use?

The main body, nut and pressing head of the Plastic Cable Gland are made of nylon PA66, and the nylon pipe fittings are environmentally friendly, non-toxic, non-secondary pollution and suitable for long-term contact with water, non-corrosive, non-toxic, non-rusty. The static working temperature is suitable for - 40~100 C, the instantaneous heat resistance is 120 C, the dynamic working temperature is - 20~80 C, and the instantaneous heat resistance is 100 C. Special clamping claw and rubber design, clamping cable range, tensile strength, waterproof, dust, salt, acid and alkali resistance, alcohol, grease and general lubricants.

The metal waterproof Plastic Cable Gland is nickel-plated brass, and the clamping claw is made of nylon. The clamping ring uses soft NBR to fasten the cable, so that the cable does not leave any marks after the joint is removed. It has a good resistance to high temperature, corrosion and high voltage, and the salt spray test is not less than 200 hours.

Installation and use:

In general, one end of the thread is fixed on the shell, and the nut is tightened in the shell to be fixed (or according to the choice of thread into the electrical equipment with the inlet and outlet as the internal thread), the cable is directly led out by the 3 Pin Waterproof Cable Connector, and the tightening nut is properly tightened, so that the cable can be protected.

Widely used in mechanical equipment, electrical, marine electrical and anti-corrosion equipment of wire and cable fixation and protection.

Main role

Tighten and seal cables. Fastening refers to the use of waterproof joints to lock the cable, so that the cable does not produce axial displacement and radial rotation, to ensure the normal link of the cable. Sealing means isolation of water and dust.

Lectotype guidance

1. According to the service environment and requirements of the cable connector, determine the IP protection grade that the cable connector needs to achieve.

2. Determine the material and color of the cable joint according to the use environment and requirements of the cable connector.

3. Determine the thread specifications and screw standards required for cable joints.

4, select and cable outer diameter, +10% around the bayonet range as a specific model;

5, under normal circumstances, it is suggested that the O seal ring must be used to achieve the technical standard of IP67.

6. According to the thickness of the machine, do you need to extend the thread?

7, if it is used in explosive or flammable gas, it needs explosion-proof connectors.

8, if there is electromagnetic compatibility requirements, it is necessary to select EMC shielded connectors.

Points for attention

1. Plastic Cable Gland with different materials in different environments.

2, it is recommended to use torque wrench to tighten (recommended).

3, when more than IP65 requirements are required, O type seals must be used.

4. In order to ensure that the joint can withstand a certain amount of pressure, it is suggested to add a protective sleeve to strengthen insulation and protection.

5. In order to ensure waterproof and long-term operation, it is suggested to use double-wall glued heat-shrinkable sleeve and insulating sleeve for reinforcement.

6. During construction, it is better to adopt staggered butt-joint mode (that is, the cable does not need to be cut off neatly butt-joint);

7, the use of self adhesive tape (or heat shrinkable waterproof tape) are all high-voltage products, to ensure insulation safety.
