How to manufacture the aviation plug connectors and control the quality of connector soldering

Most of the switches of good quality aviation plugs are made of advanced materials such as bulletproof rubber. The fire performance, moisture resistance and impact resistance are high, and the surface is smooth. When purchasing, you should consider the feel of your own touch,determine the material of the switch by hand and ask the dealer.

Waterproof Industrial Connectors

In general, products with a surface that is not too smooth and that feels thin and brittle are unreliable. A good switch socket panel requires no air bubbles, no scratches, and no smudging. The touch of the switch is light and not tight, and the socket of the socket needs to be equipped with a protective door. The plug should be inserted and removed with a certain force and cannot be inserted in one foot.

An air plug is a receptacle that has one or more circuit connections that can be plugged in, allowing it to be plugged into various lines for easy connection to other circuits. In our daily life, the power socket is commonly used. The power socket is an electrical device that provides a power interface for household appliances. It is also an electrical accessory used in residential electrical design. It has a close relationship with people’s lives. How to choose a safe power outlet is very important. Low-quality power sockets often cause personal electric shocks and electrical fire accidents, which poses a major hidden danger to personal and property safety. Therefore, the design of the power outlet is also an important basis for evaluating residential electrical design.

In the traditional production process of connectors, the soldering type is a relatively common method. The connector produced by this method is often used in places where the heat is small. This device requires a relatively small current in the part, if the current is too Large, the temperature will exceed the bearing range of the solder joint, so that the solder melts and deforms, the connection is not real or the structure is deformed, which easily causes the circuit to be short-circuited, causing damage to the entire system equipment. Reduced system stability. In addition to the processing methods, the temperature causes the cause of the de-soldering, in the production process, there are some improper handling places that will cause the phenomenon of connector de-soldering.

The most common case is that the soldered connector is not the same weight as the other connector, or the difference is too large. In the welding process, the pins of a welded part will be deformed due to the different degrees of temperature, which will cause the welding between the components to be untrue. This situation is sometimes not found during the test, only to the user. When it is used, because the equipment needs continuous high-load operation, or the equipment is in a harsh environment, the temperature changes drastically, and it runs at full load for a long time under high temperature conditions. This causes the temperature of the solder joint to be too large, and the solder deformation melts. It is easy to cause a short circuit. A more common solution to this problem is to increase the frequency of the reflow soldering fan appropriately and speed up the soldering of the connector, so that the probability of deformation of the connector pins can be reduced. However, when using this method, you must pay attention to the setting of the furnace temperature. Always pay attention to the temperature change of the furnace temperature. Do not let the temperature of the connector rise too fast. The peak value should be adjusted according to the size of the equipment and the size of the stitch. If it is the processing of the pin of the card seat, you can ask the supplier first. At the time of production, the method of cutting and re-plating is used first, or the method of electroplating and cutting first. If it is the former, the effect of tin processing will be good at this time. More. If the latter also has a solution, you can start by adding a tin amount and put a layer of steel plate sticker next to the hole, so that you can ensure that it is not welded or leaked.

How to design the safety of the aviation plug connector

There are different use of the aviation plug converter, and various situations . Here let Renhotec  introduce you more details:

The aviation plug converter will not cause a key safety indicator for electric shock accidents of users and others under normal use conditions and even unexpected situations. When the plug and the socket are fully or partially inserted, the live part of the plug shall not be accessible; any plug of the plug shall not be able to be inserted into the live socket of the socket when the other pins are in an accessible state. Plugs and sockets with protective doors and converters should prevent insertion of probes.

To ensure adequate contact pressure on the plug pins. The insert sleeve should be corrosion-resistant and wear-resistant to ensure good contact between the plug and the socket; the plug pin should be locked and cannot be rotated, otherwise the insertion performance and unsafe factors will be affected; the converter has a cord fixing device to ensure The cord is fixed and can withstand normal tension and torque; when the plug and socket are inserted, the mating surfaces should be basically tight to prevent electric shock.

An aviation plug is a seat that has one or more circuit connections that can be plugged in, allowing it to be plugged into various wires for easy connection to other circuits. In our daily life, the power socket is commonly used. The power socket is the electrical equipment that provides the power interface for the household appliances. It is also the electrical accessory used in the residential electrical design. It has a very close relationship with people’s lives. How to choose a safe power outlet is very important. Low-quality power sockets often cause personal electric shocks and electrical fire accidents, which poses a major hidden danger to personal and property safety.

Aviation plugs pay special attention to some details while purchasing good quality sockets. For example, when purchasing a household outlet, it is best to choose a functional new socket that prevents children from getting an electric shock. The socket hole preferably has a design to prevent children from inserting small metal objects such as fingers or hairpins. At the same time, parents should pay attention to the problems of household appliances aging, socket aging, etc. If there are bare wires and leakage sockets in the home, they must be replaced immediately, or wrapped with insulating tape. In addition, the socket and terminal block should be placed behind the sofa and table as much as possible.

The poor quality of the aviation plug changer is an important cause of electrical fires. The quality problems of small plugs, sockets and converters will pose serious harm to the personal and property safety of consumers. Therefore, consumers should pay attention to the safety of products when purchasing plugs, sockets, converters and switches.

How to use the aviation plug correctly

Our daily life and work are inseparable from the existence of aviation plugs. . How to use aviation plugs correctly? Here, RENHOTEC Group Electronics & Technology engineer will introduce the correct use of aviation plugs and pay attention to the use of aviation plugs. Matters.

Aviation plugs play a vital role in our life and production processes. They make the design and production process easier, more flexible, and reduce the cost of production and maintenance. Now, let’s look at the below correct ways of using aviation plug.

  • If the connector is in a separate state, be sure to take dust-proof measures; if the connector has not been separated for a long time, we must put insurance on the plug and socket.
  • Wipe with a cotton cloth dampened with alcohol while cleaning the connector, and dry it before use.
  • When the aviation plug is connected or disconnected, the center of gravity of the plug and the socket should be coincident on the same line, and use the horizontal force push or pull out.
  • It is strictly forbidden to energize when the connector is not locked or not yet linked.

All of the above are the correct use of the connector, we need to pay attention to when we use it.

Because the connector has excellent performance in improving the production process, maintenance and flexibility, it is more necessary for us to pay attention to the  method of correct using in daily use. Pay attention to the correct position when connecting and prevent the connection. To avoid damage to the aviation plug and accidents resulting in accidental electric shock.

7 problems you must know in manufacturing of aviation connector

With the continuous advancement and development of the times, in order to meet the needs of different mechanical equipment and various fields, aviation plugs have also been adjusted and improved. Today, a wide variety of aviation plugs are available on the market. Aviation plugs are now the most common type of specification, helping people to live and work more easily and quickly in the ever-changing products. High quality aviation plugs are very careful during the machining process.

For the processing of aviation plugs, we should pay attention to the following:

  1. When welding, the operator must control the amount of tin to avoid excessive tin content, which leads to the phenomenon of climbing tin. Usually, the amount of tin soldered to the male seat will be much less than that of the female seat.
  2. When using the constant temperature soldering iron, the staff should try to control the temperature within the scope of the standard and avoid the soldering iron for too long.
  3. When the staff is welding, remember not to carry out partial extrusion, especially for the plastic part of the aviation plug. If it is strongly squeezed, there may be deformation or damage due to contact with high temperature or other conditions.
  4. The relevant maximum temperature range of the furnace temperature curve should be kept at 260 °C, which cannot exceed this range.
  5. 5, we must ensure that when the furnace is over, the aviation plug will not be squeezed by the relevant external force.
  6. In the process of producing aviation plugs, solder paste will be used. We recommend the selection of high quality solder paste and environmentally sound use.
  7. Any staff member must take certain protective measures during the production process.

The above points are the summary of what we should pay attention to during the production process of aviation plugs. It is necessary to know that any mistake in the production process may cause problems in the performance and quality of the aviation plug. If it is serious, it may cause an accident or malfunction during the use process, which may cause our work and life to be imaged.

The use of aviation plugs is now very extensive. With the progress of the times, I believe that it will be used more and more frequently in our lives. I hope that through the brief introduction of Renyi Weiye technology engineers, you can gain a deeper understanding of the use of aviation plugs and related knowledge.

Forecasting and Using Tips for Aviation Plug

1) Forecast market capacity and changes in the aviation plug industry. Market commodity capacity refers to the total demand for a certain currency payment capacity. The market capacity and its change forecast can be divided into the production data market forecast and the consumption data market forecast. The forecast of capacity of the market for production materials is based on the study of the direction of development of the national economy and the key points of development, comprehensively analyzing the adjustment of the production technology and product structure of the aviation plug industry during the forecast period, and forecasting the demand structure, quantity, and trends of changes in aviation plug market.

2) Forecast the price changes in the market of aviation plug industry. The price of input products and the sales price of products in production are directly related to the level of corporate profits. In the prediction of commodity prices, it is necessary to fully study the changes in labor productivity, production costs, and profits, the development trend of the relationship of market supply and demand , the changes in the value of money and currency circulation, and the impact of national economic policies on commodity prices

3) Predict the production and development trend of aviation plug industry. The forecast of production development and its changing trend is a forecast of the supply of commodities and its changing trend in the market.

  1. High Temperature

The metallic and insulating materials of aviation plugs determine the operating environment temperature of the connector. High temperatures can destroy insulate materials, causing a decrease in insulation resistance and pressure resistance; In the case of metals, high temperatures can cause conductors to lose their elasticity and accelerate oxidation, resulting in deterioration of the coating. The typical ambient temperature is -55~100°C, which may be higher in special situations.

  1. Moist

Relative humidity higher than 80% is the main cause of electrical breakdown. The wet environment causes the absorption and diffusion of water vapor on the surface of the insulator, which easily lowers the insulation resistance to below MΩ level. Under long-term conditions in high-humidity environment, it will cause physical deformation, decomposition, escaping products, and producing respiratory effects and electrolysis , corrosion and cracks. Especially for aviation plug which is used in outside the equipment, the environmental conditions of moisture, water infiltration and contamination are often considered. In this case, sealed connectors should be used.

3.Rapid temperature change

The rapid temperature change test simulates the actual use of an air plug in a cold environment to transfer to a warm environment, or simulates a situation where the ambient air vehicle or detector has a sharp change in ambient temperature. A sudden change in temperature may cause cracking or delamination of the insulating material.

Reasons for the failure of gold plating in aviation plug holes

What is the reason for the non-gold plating in the air plug hole? In the following, Renhotec Electronics Engineer will analyze the reasons for you. When the aviation connector pin or socket gold plating process is completed, and the thickness of the outer surface of the plated part reaches or exceeds the specified thickness value, the plating of inner hole is thin or even has no gold layer.

  1. Platingparts are inserted into each other when gold plating

In order to ensure that the jack connector have certain flexibility when they are mating, most kinds of jacks are designed with a groove at the mouth. In the electroplating process, the plating parts are constantly turned, and some of the jacks are inserted into each other at the opening, so that the power lines of the plug-in parts are shielded from each other and the plating in the holes is difficult.

  1. Plating parts are connected end to end during gold plating

Some pins of aviation plugs are designed with the outer diameter of their pins slightly smaller than the hole size of the wire holes. During the plating process, some pins will be connected end-to-end to cause the inside of the wire holes to be plated without gold.

  1. The density of the blind hole is higher than that of the electroplating process.

Since the bottom of the tongue and groove of the socket is still a certain distance from the bottom of the hole, this distance objectively forms a blind hole. Similarly, there is a blind hole in the wire hole of the pin and the jack, which is to provide wire welding. The guiding effect is that when the pore diameter of these pores is small (usually less than 1 mm or even less than 0.5 mm), the concentration of blind pores exceeds the pore diameter, it is difficult for the plating solution to flow into the pores, and the gold plating solution flowing into the pores is difficult to achieve. Outflow, so the quality of gold in the mouth is difficult to guarantee.

Wide use of aviation plugs in the mechanical field

In the field of mechanical equipment, there is such a non-core component, but everything will not going smoothly if without it . That is an aviation plug. Today, basically all mechanical equipment is inseparable from aviation plugs, because it can guarantee the normal operation of the equipment and the stable transmission of signals. In the market, this connector is favored by the market and users. It is often used in the manufacturing of power equipment, minerals, mobile phones, automobiles, shipbuilding, and shipbuilding machinery. So it’s wide application is obvious。

For laymen, it thought be a kind of “artifact”when heard such a wide-ranging application component. This is not the case, Its role is very simple , just has connection effect. In other words, the two circuits are connected to realize signal transmission. As for maintenance, it is not very complicated and can be replaced directly. In addition, the aviation plug produced by Renhotec Group also has the advantages of cold resistance, high temperature resistance, corrosion resistance, and high waterproof grade. Even in a relatively harsh environment, aviation plugs can still perform very well.

What kind of value does the air plug have in real life? Let’s talk with the Renhotec Group’s engineer. According to the current environment of aviation plug applications, the power used is not the same due to different environments . And there are many types if distinguished by different ways, such as Straight Plug, Right Angle Plug; Cable type, PCB type; Round, rectangular and so on. How to choose the right one depends on the specific Application.

The application of aviation connector is closely related to our lives. How great is its role? You may wish to imagine what would happen to the world if there’s no aviation plug. Take our commonly used electronic devices as a example, it is necessary to connect to the power supply through a connector, and then connect the electronic device to other components with wires. Previously, they were fixed by welding. From the point of view of production, installation, maintenance, etc., it is not very convenient, and it takes time and effort to install, and the related cost will be increased. Meanwhile it will naturally become more troublesome to repair. With aviation plugs, the installation will be much easier and the repairs will be quicker. It will be possible to directly change them; at the same time, it will not damage the equipment itself, greatly reducing the production cost, but also conducive to maintenance.

In a word, in the whole mechanical field, the existence of the aviation plug has greatly promoted the automation of the equipment, and with the increasing demand of the connector market, the development of the connector industry has been promoted.
