Circular waterproof connector

Circular waterproof connector

Circular waterproof connector is also called aviation plug or cable connector, is a kind of waterproof aviation plug, with a circular interface and cylindrical contact shell coupling device. And it can provide safe and reliable electrical, signal and other connections.The number of cores is different, the size is diverse, but basically metal shell, plug and socket are turnbuckle, after connection, can be tightened and fixed, will not fall off.They can be placed inside the power line, network cable, etc., not only can provide normal and safe and reliable power supply, signal transmission, the most important and most characteristic role is to play a good waterproof and dustproof effect, protection level IP67. Due to the wide range of contact points, voltages and currents, they are also very versatile and flexible, widely used in automation, manufacturing, military, Marine, transportation industry, aerospace, power and other fields.

II.Advantages of circular joint waterproof connector:

1. Energy conservation and ecological environmental protection.The waterproof cable connector has a more stable electrical connection and lower contact resistance, reducing energy consumption and, as a result, it is more energy efficient than previous connectors. In addition, it also has a good ecological environment protection and reduce environmental pollution.

2. High transmission efficiency

Designers understand the connection function of connectors when designing products. Waterproof cable connectors can be connected to different circuits. In order to achieve electrification, its transmission efficiency is very high.

3. Small in size and occupies little space

When designing waterproof cable connectors, the exterior design is more compact and flexible, so it can better hide itself and not take up space.

III.For waterproof connectors, the appropriate connection method can improve the reliability of the product. In the design and selection, it is necessary to choose correctly according to the product use environment.

The connection methods of waterproof connectors are as follows:

1. Threaded connection

The thread self-locking characteristic is used to realize the connection of plugs and sockets. In order to ensure the anti-loosening under the condition of vibration and shock after connection, the fuse, setting screw or ratchet ratchet structure is generally used.

The main advantages of this structure are reliable connection and convenient use. It is mainly used in the environment of large product dimensions.

2.Bayonet connection

This type of construction is provided with three pins 120 degrees apart on the outer perimeter of the socket, and the matching plug connection cap is equipped with a suitable three-curve spiral groove.

The main advantages of this structure are fast, reliable connection and easy to use. It is mainly used in the environment of fast connection and small product size.

3.Push-pull connection

The type of structure is that the plug is designed with a set of locking shrapnel, when the plug is inserted into the socket, the locking shrapnel on the plug is embedded in the groove of the socket, and the plug is locked in the socket. When pulling the plug tail or cable, the plug and socket cannot be separated. When pulling the plug hooded housing, the plug separates from the socket.

The main advantages of this structure are quick insertion, small volume and high density. Mainly used in narrow space and the use of rotary insertion and separation difficult occasions.

IV.The wiring method of waterproof plug mainly includes the following steps:

1.Preparation: First, get the necessary tools and materials, including wire strippers, insulation tape, connection cables, and waterproof plugs.

Peel off the cable sheath: Use wire strippers to carefully peel off the cable sheath to expose enough wire length while ensuring that the insulation inside the wire is not damaged.

2.Stranding wires: The stripped wires are correctly matched according to color and function, and the wires are twisted together with fingers or pliers to ensure that there is no loosening or crossing between the wires.

3.Connect the wire: Insert the stranded wire into the corresponding hole of the waterproof plug. Depending on the design of the plug, there are usually screws or clips to hold the wires in place. Use a screwdriver or wrench to tighten the screws and ensure that the wire is in good contact with the metal of the plug.

4.Insulation treatment: Use insulation tape to insulate the connection to prevent current leakage or short circuit. Wrap electrical tape around the joint and be sure to cover the wire and metal parts of the plug.

5.Test connection: After wiring is complete, use a multi-meter or test instrument to test the connection to ensure that the plug can conduct current normally and no short circuit occurs.In addition, the use of waterproof plug precautions include avoiding strong impact or fall, so as not to damage the internal structure, affecting the sealing performance. When the waterproof connector is in the separated state, a protective cover should be installed or other methods should be used to prevent dust. When cleaning the waterproof joint, you can use a silk cloth dipped in anhydrous ethanol, dry it and then use it again.
