Aircraft Connector/UAV Connector

Modern military and commercial aircraft use a large number of electrical and electronic systems to monitor and fly the aircraft, manage the engine, provide communication, etc. at the same time, coupled with some entertainment equipment, the installation of these systems means that each aircraft needs hundreds or even thousands of aircraft cable quick connectors and uav connectors.

As we all know, manufacturers in the aerospace field have the highest requirements for the electrical and electronic interconnection industry. As with the military, the selection and use of aerospace electrical connectors are greatly influenced by standards and approvals, overall performance and weight, and space savings.

The location and application determine the requirements to be met by the aircraft electrical connectors/aircraft electrical terminals. These requirements include dielectric withstand voltage, operating temperature, insulation resistance and electromagnetic interference resistance, vibration / shock, flammability and smoke / toxicity, etc. Generally, the most important requirement for airborne electronic connector is to be able to handle shock, vibration, general durability and temperature cycle.

Advantages Of Rectangular Aircraft Connectors/UAV Connectors

Rectangular connectors can stack multiple connectors, so they can provide higher contact density. This is a big advantage if the space is limited and the I / O count is high. At the same time, connection and wiring density are also very important size considerations. UAV cable connectors can offer reliable connections that ensure stable data and video transmission, power supply, and control signals. High wiring density in a connector can increase the overall weight of the connector, impacting the flight performance of the UAV. As such, manufacturers need to strike a balance between the number of wires and the overall size, weight, and compatibility of the connector.

Why Choose Sunkye As Your Aircraft Connectors/UAV Connectors Supplier

An aircraft or UAV connector is worth mentioning that because of the increasing frequency and data transmission requirements of commercial aircraft, the aircraft electrical connectors of commercial aircraft need multi-function to meet different applications. Includes insertion options for signal, power, RF, and fiber terminals, as well as hybrid insertion that can include all of these options.

For the aircraft electrical cable connectors applied in the fuselage, higher data transmission rate and the distance that data must pass are also critical. Some solutions need to design the signal integrity of the whole cable components and connectors, and select the solid and reliable aircraft electrical connectors that meet the requirements of data rate and EMI shielding.

For high-speed data links (copper optics, fiber optics) are increasing. If the aircraft power connectors can adapt to the high speed, but still can not make the terminal too cumbersome, it can meet the needs of more customers.

With the increasing demand for high-density connectors in the medical market, the irreversible trend of connectors in the medical field is becoming smaller, lighter and more ergonomic. In this trend, both high-density connectors and the medical connector industries are experiencing significant growth.

High-density connectors are connectors with large numbers of individual contacts such as PIN pins in a relatively small connector body. There is no clear boundary between standard power connectors and high-density connectors, but the designation of high-density connectors is usually defined by having more contact points in the same shell size.

The growing demand for high-density electrical connectors is driven by many factors, especially the size, weight and function requirements. Component size and weight have long been a key factor in many military and aerospace applications. With the increasing popularity of portable and patient wearable devices, the custom medical connector is becoming more and more important in the medical market.

To meet the growing demand for the higher density connector market, many manufacturers are developing standard and ready-made high-density connectors solutions. When connectors need to meet a specific application and the output is limited, this solution is effective and feasible.

However, the development of standard high-density connector products will be targeted. Connector manufacturers must consider a variety of characteristics when developing to meet a wide range of application needs and budget constraints. Mature connector manufacturers with industry-leading ideas can successfully use this strategy, but this strategy is not universal.

High-density connectors will continue to develop, and the trend of products will be towards miniaturization, high precision and hybrid functions. With the gradual realization of these product technologies. Engineers will surely develop new connection technologies to further improve contact density, size, weight, performance and function, and to further ensure product reliability and safety. Standards and customized solutions will greatly meet the growing demand for high-density electrical connectors in the medical market.

The connection forms of industrial different electronic connectors can be roughly divided into four types, and more common types of electrical connectors are currently used. Here are four industrial electrical plug types:

Threaded connection

Some types of connections are commonly used for contacts with larger dimensions and the military electrical connector that operate in high vibration environments. This type of connection can be equipped with a fuse to prevent loosening after the connection is completed. The connection is reliable, but the connection is slow.

Bayonet connection

This is a reliable and fast form of connection and disconnection. Most electrical connectors in the form of a card 121 connection have a visual display of proper connection and locking, and can be seen through a small hole on the side of the electrical connector’s connection nut.

In-line connector

This is a versatile form of connection. When the plug and military socket of the electrical connector are connected and disconnected, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only requires a small working space to complete the loading and unloading. Common plug-in connections come in spherical or pin configurations. Because there is no mechanical labor-saving mechanism in the connection form, once it is inserted incorrectly, the mechanical resistance increases significantly and can be found in time.

Electrical connector cabinet connection

As one type of the industrial electrical connector industry, it was used on some devices and requires a blind connection near the frame. It can make electrical equipment lighter, smaller, easier to maintain and more reliable.

This type of connection prevents the operator from feeling the connection. It is necessary to design an accurate positioning device to avoid forcibly connecting the wrongly inserted micro electrical connectors together, so that the wrong insertion cannot be performed. Cabinet-type electrical connectors are usually designed with floating or resilient contacts to ensure proper connection.

USB, the abbreviation of universal serial bus in English, is an external bus standard, which is used to regulate the connection and communication between computers and external devices. It is an interface technology applied in the field of PC.

Universal serial bus (USB) is a new data communication mode which gradually replaces other interface standards. It was jointly developed by Intel, Compaq, digital, IBM, Microsoft, NEC, Northern Telecom and other computer companies and communication companies in 1995, and gradually formed industry standards.

As a kind of high-speed serial bus, USB bus’s extremely high transmission speed can meet the application environment requirements of high-speed data transmission, and the bus also has the advantages of simple power supply (bus power supply), convenient installation and configuration (plug and play and hot plug are supported), simple expansion port (127 peripherals can be expanded at most through the hub), diversified transmission modes (4 transmission modes), as well as the advantages of good compatibility (downward compatibility after product upgrade).

Since its introduction, universal serial bus has successfully replaced serial port and parallel port and has become one of the standard expansion interfaces and necessary interfaces for a large number of computers and intelligent devices in the 21st century. Now it has developed to USB version 3.2. USB has the advantages of fast transmission speed, convenient use, hot plug support, flexible connection, independent power supply, etc. it can connect a variety of peripherals such as the keyboard, mouse, large-capacity storage device, etc. the interface is also widely used in smartphones. The interaction between intelligent devices such as computers and external data is mainly based on network and USB interface.

Main Features of USB Connector

1. Polarization

The USB connector can only be nominally inserted in one way. It is possible to force a wrong connector, but this can cause damage to the device.

2. At least four contacts

All USB connectors have at least four contacts (some USB models may have five, USB 3.0 connectors or more), which are used for power, ground and two data lines (D + and D -). The USB connector is designed to transmit 5V up to 500mA.

3. Shielding

The USB connector is shielded, so it provides a metal shell that does not belong to the circuit, which is very important to keep the signal intact in the environment with a lot of electrical “noise”.

4. Powerful power connection

It is very important for the power pin to establish a connection before the data line to avoid trying to power the device through the data line, which is taken into account in the design of all mil spec USB connectors.

5. Mould strain relief

All USB cables are plastic-wrapped at the connector to prevent pressure on the cable and damage to the electrical connection.

For micro pitch connectors manufacturers, in addition to their productivity, they also care about product quality. When it comes to product quality, many aspects will be involved, such as the performance of high-speed micro-pitch interconnects for connectors.

In general, there are nine main methods to improve the high-speed micro pitch connectors:

1. Connector products, in the early stages of design, need to perform multiple simulation cycles to accurately quantify product performance before starting an expensive processing process.

2. When the military grade connector is mated, the stub in the contact area should be minimized. The longer the stub, the better the reliability, but the stub is an electrical load like an antenna.

3. Simplify contact geometry and improve signal path performance.

4. Shorten the pin length to minimize the distance that the signal must travel.

5. Add asymmetric footprints and contacts as much as possible, because the alternating design reduces pair-wise crosstalk between rows of pins and between rows. It can also be said that footprint should drive connector performance.

6. Optimize the connector branch area (BOR). Think of the connector as a key node in the link, not only focusing on the node, but also the link.

7. Where space permits, incorporate a common ground plane into the connector.

8. The choice of plastic molding will obviously affect the performance of military type connectors. These attributes should be carefully considered: high-temperature plastics suitable for RoHS, matching Dk to obtain the required impedance control, dimensional stability of temperature and time.

9. The shorter and straighter the contact between the signal path and the connector, the better its signal integrity. But the balance function is that the connector must have sufficient normal force and exit force, and it also needs to have a certain degree of robustness.

FPC connectors are also known as flexible circuit printed connectors, it is a flexible medical equipment fpc. and the most prominent characteristics are the high cable density, thin and light shape and high transmission speed. The FPC connector with high density and small spacing is the main development direction. It can ensure the current fluency and transmission reliability to the greatest extent in use. It also plays the role of transforming electrical signals into optical signals. Therefore, the market demand is growing.

FPC connectors are widely used in various fields and play an important role in electronic equipment (computers, LCD displays, scanners), mobile equipment (mobile phones, tablets, laptops), printing equipment (printers, copiers), navigation equipment (vehicle GPS navigation)  and medical equipment. Therefore, the FPC connector must be tested before application to ensure that the performance and quality of the FPC connector can meet the standard.

High-current leaf spring micro pin module can be adopted in electrical test connectors. The reason is that the high-current leaf spring micro pin module has a strong over-current ability, which can meet the demand of high current transmission by FPC connector test; secondly, for small spacing FPC connectors, the value of high current spring micro pin module can cope with the minimum spacing of 0.15mm, and the connection is stable and continuous; the key point is that the high current leaf spring micro pin module has an average service life of more than 200 thousand times, which can effectively deal with high frequency test of FPC connectors. The high current leaf spring micro pin module can not only improve the testing efficiency, but also reduce the cost.

There are many specifications for FPC connectors, and the number of pins for different types of FPC connectors varies. The connectors are specially different in use. For example, the connection method of FPC connectors can be divided into upper connection, lower connection and double-sided connection, which can be identified by observing the contact surface of metal terminal pin of the FPC connector. The the contact surface of the metal terminal is on the top of the FPC connector if it is the upper connection, while the contact surface of the metal terminal is below the FPC connector if it is the lower connection. In the double-sided connection, the connection mode of front-insertion and back-open supports the connection of upper connection and lower connection. Double-sided connection is mostly used in FPC connectors among these connection modes.

The circuit diagram of FPC connectors is becoming more and more subtle, and its application requirements are also more precise. FPC connectors need to be used skillfully, and there are several points that need special attention:

1. In the use process, insert the pin of the FPC connector slowly at a right angle. Pay attention not to inserting the pin obliquely, so as to avoid that the pin is not connected in place; do not pull or unplug the connection cable at will, which may cause the data exception or data loss of the FPC connector.

2. The FPC connector is composed of multiple pins. Please avoid swaying or shaking the connector in use, because it may cause the offset of the FPC connector connection position and affect the use.

3. Once the pin of the FPC connector is broken or bent, it should be replaced immediately to avoid unnecessary hidden danger. Otherwise, the transmission of FPC connector circuit will be poor, which will cause the short circuit and overburning of the connector.

4. When opening the cover of FPC connector, too much force should be avoided. Overexertion will deform and damage the cover, and it may also lead to the break of connector terminals.

5. In the welding of FPC connectors, it is necessary to pay attention not to adding too much solder in reflow soldering when operating the bonding pad, otherwise, the connector terminal can’t be welded stably and insufficient soldering phenomenon may also occur.

Sunkye FPC pcb right angle connectors have the flexible characteristic. As a carrier of current transmission, FPC connectors can play an excellent role in many fields. In addition to paying more attention to the use of FPC connectors, we should master the performance more.

Connector backshell definition

Consistent with the high standard tradition of military products, mil standard connectors are designed specifically for the needs of the armed forces for durable and reliable products. These connectors are of different shapes and sizes, and they are used in many fields, from communications offices to the front lines of war to naval warships. Like warriors, mil standard connectors are designed to be robust and accurate.

The first mil standard connectors were developed for aviation and tactical service applications in the 1930s. The land-sea series (AN type) had a far-reaching impact on all the connectors and set standards for modern military circular connectors. These connectors, called mil standard connectors (MIL-STD), are often used in aviation, industry, navigation and automotive industries. The most common types of connectors for military applications include round mil D38999 connectors or rectangular (M24308) connectors. Mil standard connectors reflect the military’s emphasis on consistency, accuracy and strength. And in a series of applications, they have assisted the army, Navy and air forces in their operations. These connectors are manufactured in accordance with military specifications, and the military component codes printed along with them make them easy to identify and purchase in many commercial products.

For special connectors needs applications, they must include moisture resistance, heat shrinkage, and welding:

1. Moisture proof connector

The special moisture-proof joint connector is filled with silicone material to help prevent moisture, dust and other debris from entering the connection.

2. Heat shrink joint connector

In heat-shrinkable tubes, heat-shrinking involves melting the lining. When heated, the lining becomes a gelatinous substance, sealing off moisture and dust, and providing an extremely strong adhesive to hold the wires in the military spec connector.

3. Solder joint connector

The solder joint connector contains heat shrinkable and low melting point solder and a protective gland for hermetic connection. These welded joints are unique in that many of these welded joints can often be applied without crimping and can be sealed simply by heating.
