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.

Basic structure of circular connector_ Advantages and disadvantages of circular connector

Basic structure of circular connector_ Advantages and disadvantages of circular connector

Circular connector features The plugs and sockets of circular connectors are mostly connected by threads. Their terminals can range from two to hundreds. They are characterized by small size and high reliability, and can meet the requirements of cable connection between electronic equipment. Basic structure of circular connector 1. Contact The contact is the central part of the circular connector to complete the electrical connection function. Generally, a contact pair is composed of a female contact and a male contact, and the electrical connection is achieved through the insertion of female and male contacts. 2. Appendage Accessories are divided into structural accessories and device accessories. Structural accessories such as locating pin, circlip, connecting ring, sealing ring, guide pin, locating key, cable clamp, sealing gasket, etc. Device accessories such as spring ring, nail, rod, nut, etc. Most of the accessories have general parts and specifications.

Selection guide and necessary knowledge of LED waterproof connector

Selection guide and necessary knowledge of LED waterproof connector

1、 First of all, the selection is based on meeting the requirements of relevant electrical, installation, connection, insulation, protection and other technical standards. Second, we should not only look at standards, but should go beyond them and pay attention to the situations encountered in practical application. As some standards selected for connector design and production in the LED industry are actually borrowed from other industries, many clauses do not meet and satisfy the rapidly changing requirements of the LED industry due to the relatively short application time in the industry, such as the inspection of aging resistant materials, which is only said to be in line with the field engineering application, but how to define it depends on whether the UL yellow card is based on the test, Whether the service life of field engineering is subject to the commercial contract of the project manufacturer or the "service life of skills" that we can recognize directly affects the selection and design of product materials, which is also the reason for the variety of led connector materials.
