H20 Female plug welded type Aviation Plug

Aviation plugs can also be called plug sockets, widely used in a variety of circuits, play the role of connecting or disconnecting circuits. Manufacturers are first responsible for improving the reliability of aviation waterproof plugs. However, due to the variety of aviation plug, widely used, the correct selection of aviation plug is also an important aspect to improve the reliability of aviation plug. Only through the joint efforts of the manufacturer and the user can the functions of the aviation plug Waterproof Connector be maximized.

But any product that has been used for a long time needs to be cleaned and maintained effectively. Only in this way can the performance of the product be maintained and the service time of the product be extended. Today, aviation plugs and round waterproof connectors are part of many household appliances and electronic devices. Therefore, people began to pay high attention to how to maintain the aviation plug.

For aviation plug maintenance measures, should pay attention to the following points:

1. When unplugging, the operator should hold down the head of the connector instead of pulling it out by pulling the wire. This is likely to result in a rupture of the internal loop, thus shortening the service time of the aviation plug.

2. Do not place the aviation plug Circular Connector in a dusty or humid environment. This may lead to the presence of oxidation of the connecting wire, resulting in poor contact.

3, if there is improper use of the enterprise, it is also very simple and easy to affect the damage of the connection line. Usually people need to meet the connection line when there is a problem, many people choose to find a tape wrapped, so it is easy to lead to short circuit or break the system has appeared, so that the aviation plug can not carry out normal operation.

4. If we find that the power cord related to the aviation plug has aging phenomenon, it should be able to be replaced in time.

5. If you haven't used an aviation plug in a long time, unplug it and wipe it off with a professional alcohol sponge or paper towel. After cleaning, you need to wait for it to dry and then put it in a dry place.

How to choose aviation plug?

Consider electrical requirements for aviation plugs. Electrical requirements first consider the requirements of voltage and current, whether it can be well applied to this type of electrical, but also consider the change of resistance, millivolt drop, maximum current, maximum voltage, characteristic impedance, plug loss, etc.



The mechanical properties of aviation plug determine the mechanical properties of all kinds of electronic and electrical equipment. When choosing, we should consider how much volume and coverage area, how much stabbing and pulling output of terminals, and how durable.
