Tips for using aviation plugs and circular connectors

Tips for using aviation plugs and circular connectors

When the aviation plug is terminated, it shall be terminated and checked in strict accordance with the corresponding termination specifications or requirements, and terminated according to the corresponding node serial number. The thickness of the zui large insulating layer between the selected cable conductors shall match the distance of the contact, and the cable core shall match the terminal of the contact. When the contact is crossed and parallel, it shall be handled. The welding type shall not be subject to high temperature for a long time, which will affect the life of the welding quilt. After welding, each wire must be tested to see if it is unblocked and marked. During welding, electric soldering iron of corresponding power shall be selected according to the diameter of bare wire. The welding time of each contact shall not exceed generally. Attention shall be paid not to let the flux enter the insulator to prevent the insulation resistance of the product from falling. When the aviation plug is in a separate state, it shall be separately equipped with a protective cap or adopt other dust-proof measures; If the aviation plug socket is connected for a long time, a safety can be provided between the plug and the socket.

What influences industrial connectors? These factors cannot be ignored

What influences industrial connectors? These factors cannot be ignored

Point 1: Vibration When placed in an extreme vibration environment, the standard connector will react. After a certain period of time, the connection between the plug and the socket will gradually wear out, and the pin will sag at the connection point, reducing the reliability. Moreover, after such wear, if exposed to steam environment, corrosion will be further aroused. Second point: electromagnetic interference Serious EMI sources usually include consumer equipment, power channels, etc. near several channels. The machine and the electrical path generate electric fields, which can be coupled into the digital path to cause noise and damage the integrity of the digital signal. Third point: extreme temperature Today's connectors can generally withstand a temperature difference of - 10 -- 60 degrees. There is no problem with most office and general industrial environments. However, if it is placed in an extremely harsh temperature environment, the temperature beyond the range will lead to transmission errors and reliability problems. Point 4: Corrosive materials Corrosive gases and liquids are often encountered in industrial environments. Oil, gas and chemicals can corrode the external connector covers, the metal feet of plugs and sockets, cable jackets, etc.

Connection form and use of industrial connector

Connection form and use of industrial connector

1. Thread connection method: Some touch devices with large size and electrical connectors operating in strong vibration environment often choose a connection method. This connection method can install a fuse to avoid looseness after the connection is completed. The connection method is reliable, but the continuous unloading speed is slow. 2. Connection method of bayonet: It is a reliable and agile method of connection and separation. The electric connectors of most card 121 connection methods have correct connection and definite visual display, which can be observed from the small hole on the side of the connecting nut of the electric connector. 3. Plugging connection method: It is a versatile cohesive method. When the plug and socket of the electrical connector are connected and separated, their moving direction is usually reciprocating linear motion, without torsion and rotation, and only a small working space is required to complete the connection and removal. The common plug and pull connection has two structures: ball or pin. Because there is no mechanical labor-saving mechanism for this connection method, once it is inserted by mistake, the mechanical resistance increases significantly and can be found in time.

Basic performance of waterproof connector

Basic performance of waterproof connector

It can mainly be divided into mechanical and electrical performance and environmental performance. The plugging force is the mechanical product characteristics, and the plugging and separation development needs us to fully meet the different requirements. If the insertion strength is small, but the tension is large, and the connection is not firm, the service life of the mechanical equipment depends on the size accuracy of its connection and quality management work. Waterproof connector is a connector that can be applied to the environment with water and can ensure the normal use of the internal mechanical and electrical properties of the connector under certain water pressure. Aviation plug is an electromechanical component that connects electrical circuits, so its own electrical parameters are the first thing to consider when selecting aviation plug. The correct selection and use of aviation plugs is an important aspect to ensure the reliability of circuits. In the industrial environment of automobile waterproof connectors, such as LED lighting, urban outdoor lighting projects, lighthouses, cruise ships, aviation, industrial equipment, cables, sprinklers, etc., waterproof connectors are required.

Detailed explanation of four functions of industrial connector

Detailed explanation of four functions of industrial connector

Industrial connector is a connector used for the circuit, wire and cable of electrical equipment in the equipment industry. Its primary purpose is to maintain its normal operation, so that it will not be affected by the external environment and foreign substances to cause electrical equipment failure, or even short circuit. The industrial connector has four basic functions: connection function, electrical function, environmental function and maintenance function. The connection function of industrial connector is the first part of its function. Among them, testing the insertion and removal force of industrial connectors is a testing method to check whether its function is qualified. The national standards and international standards have clear rules on the larger penetration force and smaller separation force of industrial connectors: generally, the penetration force is required to be small, while the separation force requirements change according to the actual situation. If it is too small, it will affect the touch reliability of industrial connectors. The connection function of the industrial connector also determines its mechanical life. First of all, it is required to check whether the industrial connector can maintain its normal working condition after multiple plug and pull operations in accordance with the detection standard of one penetration and one pull (generally, it is required to see whether the connector can continue to complete the connection function after the plug and pull cycles). The structure, sliding friction index and scale accuracy of the same touch element affect the service time of industrial connectors.

Why use industrial connectors

Why use industrial connectors

The traditional connector is easy to be damaged by wind, rain and sun outside. The damage of the shell exposes the inside to the outside, forming a lot of insecurity and reducing the utilization rate. If maintenance or replacement is required, the maintenance cost is also a huge figure. Therefore, in order to make up for the shortcomings of traditional connectors to meet the needs at that time, industrial connectors came into being. According to different environments, we can divide industrial connectors into many different standards, which can well protect the safety of power systems in the wild and even in some harsh environments. What we want to summarize today is why we use industrial connectors. Users who have been in contact with the industrial connector industry know that this is a product completely different from ordinary connectors. Industrial connectors seem to deal with many problems that ordinary connectors cannot handle. Take for example. When we are at home, the connectors used normally have no protection function. When we were young, our family told us not to touch any plugs and sockets with unwashed hands. However, industrial connectors can be used outdoors, resistant to wind and rain, and can be completely immersed in water according to different protection levels.

Methods for judging the quality of waterproof connectors

Methods for judging the quality of waterproof connectors

1. Size and structure: waterproof grade of waterproof connector is generally IP68/IP67/IP66/IP65. Generally speaking, the smaller the size of the product, the harder it is to meet the requirements in terms of waterproof and connection, and the lower the waterproof grade. In terms of structure, it should be observed whether the positions of easily damaged parts and waterproof positions are reasonable. For example, the silicone gasket should not be exposed too much to prevent the UV corrosion from affecting the function and life. 2. Shell raw materials: shell raw materials should be selected with strong resistance, temperature resistance, flame retardancy and corrosion resistance, such as PA66; Wire shall be made of materials with strong flexibility, flame resistance, abrasion resistance and corrosion resistance, such as PVC or rubber.
