What are the requirements of connectors for different industries?

Connectors are widely used now. Connectors are needed in many fields, such as aerospace, ocean engineering, communication and data transmission, new energy vehicles, rail transit, electronics, medical treatment, etc. the requirements for connectors in each field are different. Let's talk about how each neighborhood works

1. Aerospace

Aerospace connectors are aviation devices used in aerospace vehicles and satellite electronic equipment. They not only need to provide effective operation, but also can withstand the special environmental tests in high-altitude aircraft, which means that these connectors must be reliable and durable.

Due to the uniqueness of different Aerospace connector tasks, the shape, size and material requirements of connectors may be different, resulting in different requirements. For example, due to the extremely limited space on a spacecraft, the aviation connector must be compact and compact. Secondly, weight is also an important factor that must be considered. Of course, the most important thing is reliability. The connector must be able to withstand the test of severe environmental conditions (external impact, extreme high and low temperature and vibration).

2. Ocean Engineering

If the watertight cable is compared to the arms and legs of various underwater equipment, the underwater connector is just like a joint. It is one of the important parts to ensure the normal operation of underwater equipment. It ensures the mechanical connection between equipment and realizes the transmission of optical, electrical signals and electric energy. It is suitable for various ROVs, undersea cameras, underwater sensors, towed arrays, undersea observation networks, marine pastures and other underwater application scenarios, and is widely used in ships Offshore oil, ocean exploration and other offshore engineering fields.

With the increasing types of application equipment in the marine field, the types of watertight connectors are also increasing.

According to the material, it is divided into metal connector and rubber connector;

According to the transmission mode, it is divided into electrical connector, optical connector, photoelectric composite connector, network electrical composite connector, etc;

According to the sealing mode, it is divided into transverse watertight connector and longitudinal watertight connector.

3. 5g communication and data

As one of the indispensable and important accessories in communication equipment, connector accounts for a large amount of value in communication equipment. Communication terminal equipment mainly includes switch, router, modem, user access terminal equipment, etc. In recent years, the rapid development of mobile Internet and the rapid growth of global data traffic have promoted the development of network equipment

The typical bandwidth demand of 5g carrying forward, intermediate and return (access, convergence and core) is significantly increased compared with 4G. It is imperative to build a new communication network, expand and upgrade equipment, and drive the connector to develop at a high speed. With the deployment of 5G and the large-scale promotion of autonomous vehicle, the opportunities for connector in the field of telecommunications and data communications are expected to develop rapidly, including high-speed backplane connectors for communication equipment, 400G high-speed digital interface, high-end RF coaxial connectors, optical connectors, and high-speed and reliable connector products for 5G infrastructure. It is expected that driven by 5g, the communication connector is expected to increase both volume and price, which will greatly expand the market space. At the same time, the equipment upgrading of the data center will increase the demand for high-performance backplane and mezzanine connectors and power interfaces. The massive increase in data traffic transmission and backhaul will require new high-speed interconnection connectors, including SFP, SFP 28 and qsfp28, as well as optical fiber patch cords and jumpers.

4. Military connector

Military connectors are necessary components of new high-performance weapons and equipment such as reconnaissance aircraft, missiles and smart bombs. They are mainly used in high-tech fields such as aviation, aerospace, weapons, ships and electronics. Military connector is the basic component necessary to form a complete weapon equipment system. Compared with commercial connector, it is a kind of special and sensitive connector with remarkable characteristics: strict manufacturing tolerance, firm structure, high reliability, high cost and resistance to harsh environment. Traditionally, the connectors used in military industry mainly include circular, rectangular, printed circuit board, RF and a small number of special connectors. With the continuous improvement of military informatization, the scale of China's military connector market has increased rapidly. Due to the need of domestic substitution of military products, the R & D investment of relevant enterprises has been increasing, and the market competitiveness of the company has been improved through mergers and acquisitions of relevant enterprises. In the future, with the continuous improvement of military informatization and the acceleration of military modernization, the demand for a large number of new equipment will increase, and the market scale of military connectors is expected to continue to expand.

5. New energy vehicle

In 2013, the automotive field accounted for only 16.27% of the connector market, and the development speed of this field has been remarkable in recent years. There are more than 100 kinds of traditional automobile single car connectors, with a number of about 500. With the improvement of people's requirements for automobile safety, environmental protection, comfort and intelligence, automobiles also use more kinds and numbers of connectors. The data show that the number of connectors used by new energy vehicles is 800 to 1000, which is far higher than the average level of traditional vehicles. Connector products are also widely used in supporting charging piles. According to the data, the average price of a single new energy vehicle charging pile is 20000 yuan, of which the cost of the connector is about 3500 yuan, and the value of the charging pile connector accounts for a large proportion.
