Product Introduction

———    —

Watertight connectors are a new generation of connectors that provide working power and signal transmission for underwater engineering. They can meet the needs of deep engineering use of marine instruments and equipment, and can provide underwater sealing in harsh sea conditions. They are also resistant to seawater corrosion and can be used in both shallow and deep waters. They are suitable for transmitting electrical signals in various underwater operation equipment, underwater robots, and underwater vehicles.

The waterproof connector has a socket and a plug. One end of the socket is inserted into the plug, and the other end of the socket is connected to the sealed compartment. This product has small size, compact structure, light weight, good sealing reliability, high mechanical strength, water pressure resistance, easy assembly and disassembly, can prevent wire twisting during installation, and can meet the transmission of electrical signals.

The types of watertight connectors include miniature watertight connectors, standard watertight connectors, right angle watertight connectors, large current watertight connectors, Ethernet watertight connectors, high-pressure watertight connectors, and underwater sealed cabins.

Product installation requirements

———    —

Installation requirements：Within a diameter range of 25mm around the installation threaded hole, the end face roughness should be above RA1.6

Notes:

1. Please be sure to apply conductive silicone oil before each insertion

2. When pulling it out, pull it out straight and do not twist it left or right

3. Do not directly unplug the cable, the cable should avoid sharp angle bending

4. When using bulkhead joints, ensure that the joints are not subjected to tilting external forces

5. All joints must not be excessively exposed to heat sources or direct sunlight

Base installation method

———    —

1. Before installation, ensure that the contact parts of the connector are free of dust, oil stains, and other impurities. It is necessary to first process the flat or threaded holes of the installed holes, and the drilled holes should be clean and free of burrs. The roughness of the hole surface should be Ra1.6um. At the same time, check whether the connector is damaged or deformed;

2. Before installation, confirm whether the voltage, power, water pressure, and water temperature match the parameters of the connector;

3. When installing cabin penetrating components, the O-ring needs to be coated with silicone grease to ensure that it is in the O-ring groove and avoid squeezing and damaging the O-ring, which may cause water ingress into the cabin;

4. Confirm polarity: Before plugging or unplugging, confirm the male female correspondence of the connector to avoid incorrect connections;

5. Screw one end of the threaded part into the threaded hole, ensuring alignment with the threaded hole, and fasten the threaded part to the shell with nuts and washers. (Note: Recommended torque values for threaded installation.)

Instructions and precautions for the use of cables

———    —

1. Cleaning and inspection: Before plugging or unplugging, ensure that the contact parts of the cable are free of dust, oil stains, and other impurities;

2. Confirm polarity: Before plugging or unplugging, confirm the male female correspondence of the cable to avoid incorrect connections

3. Due to the special process of ultra small products, it is necessary to use installation tools for installation (carried with the goods):

4. Locking and fixing: For connectors that need to be locked, ensure that the locking cap is tightened to prevent loosening due to water flow impact;

5. Straight insertion and removal: When inserting and removing, it should be done straight without bending the connector to avoid damaging the internal wires;

6. When using connectors, do not directly unplug the cable (hold the plug), do not bend the vulcanized area between the head and the cable for a long time, do not apply force to the waterproof head of the cable, and do not press heavy objects on the vulcanized area of the cable to prevent excessive bending and deformation. Excessive force can cause the welding point to fall off, resulting in virtual connection and affecting performance;

7. Cables should avoid sharp angle bending, and the bending radius should be a multiple of the cable diameter (the bending radius varies depending on the cable diameter, and the details depend on the cable specifications);

8. Before underwater operations, confirm that the connectors are locked (coaxial, ultra small, flange components, photoelectric connectors are plugged in and locked before underwater connection) to prevent short circuits caused by excessive water pressure and water seepage.
