How terminal connectors work

Terminal connector is a widely used connection device in the electronic industry, which has a wide variety of types, including row of pins, snap type and pin type three basic structure types, of which the pin type is the most common.   Terminal connectors are mainly connected to wires or cables by crimping, threading, welding and other means. It consists of two or more metal terminals, mainly used to facilitate the connection of wires and improve production efficiency. Common connection methods of terminal connectors include the following:   1. Crimping: achieved by pressing the metal terminal into the parent body or plastic shell. This method is relatively simple, easy to operate, and suitable for occasions that require frequent disassembly.   2. Threaded connection: This is achieved by threading the metal terminal to the parent body or plastic housing. This method is suitable for the occasions that need to be frequently disassembled, but it should be noted that the strength of the threaded connection is not as strong as the crimping. 3. Welding: This is achieved by connecting the metal terminals to the parent body or plastic shell by welding. This method has the highest connection strength, but requires professional welding equipment and technology.

Functions of switching connectors

Switch connector is a very common component in electronic products, and its basic properties include mechanical, electrical and environmental properties. Its main function is to connect power and electrical signals. In electronic equipment, the switch connector plays a very important role. It can ensure the effective transmission of electrical signals, but also is one of the important measures to protect electronic equipment from external interference.   The working principle of a switch connector is that when a force is applied to the switch connector, the elastic element inside the switch connector moves and presses the switch, thus controlling the transmission of power or electrical signals. The elastic elements of switch connectors include spiral spring tubes, diaphragms, etc., as well as magnetic switches, mercury switches, micro switches, and other types. There are many types of switch connectors, including coaxial switch connectors, USB connectors, DVI connectors, HDMI connectors and so on. Different types of switch connectors are suitable for different application scenarios. For example, USB connectors are mainly used to connect computers and external devices, DVI connectors are mainly used to connect computers and monitors, and HDMI connectors are mainly used to connect computers and TVs, etc.   The performance and quality of switch connectors directly af

Types of optical fiber connectors

An optical fiber connector is an electronic device that is mainly used to connect various parts of an optical fiber line to achieve low-delay, ultra-high-speed information transmission. The types of optical fiber connectors are very rich, and can be divided into ST type, SC type, LC type and FC type according to the different connection ports. The difference between these connectors is mainly in their structural design and scope of application.   The ST connector is a connector widely used in optical fiber distribution frames, which is characterized by a very tight connection between the pin and the connector body, so it has high stability and reliability. The pin of this connector is usually round, and the connector body is square, so it is also called a "square head" connector. SC connector is one of the most used types at present, which is characterized by a very tight connection between the pin and the connector body, so it has high stability and reliability. The pin of this connector is usually square, and the connector body is round, so it is also called a "round head" connector.   LC connector adopts modular optical fiber connector, which is a device to realize low loss connection between optical fibers or between optical fibers a

The history of connector products

Connector products first appeared in 1939 in World War II, with the post-war development of television, telephone and other consumer electronics, connectors quickly expanded from military use to the general consumer electronics, automotive, and computers and other consulting areas. Chinese connector industry sprouted in 1940, by the United States investment in production, the initial use of the same military applications; after the withdrawal of U.S. investment in 1949, part of the technology and equipment left in China, which constituted the prototype of the development of the Chinese connector industry. From 1950 to 1970 for the initial development of China's connector industry, during the pre-war private enterprises and related enterprises to form a public-private partnership, and to establish various ministry factories and local state-owned factories, collective factories: such as 796 factories, 851 factories, Beijing radio components nine factories, Shanghai radio nine factories, etc.. At this time the production of connectors are mainly used in places associated with the military industry, aerospace industry. Since the implementation of China's reform and opening policy in 1980, connector products gradually into the livelihood of consumer electronics industry, due to China's ongoing reform, the implementation of the open door policy, attracting a large number of foreign investors to enter the Chinese mainland market through investment. 1987 was established in Shenzhen Sandu SAS Electronics Co. After 1990, the adoption of foreign investment policies and incentives in mainland China, encouraged by the connector manufacturers around the world almost all production bases have been transferred to China, including some of the world's major connector manufacturers: AMP, MOLEX, AMPHENOL, etc.. In foreign coun

The future of electronic connectors is faster, smaller, smarter and more environmentally friendly

Small connector, in fact, there is a big name, because the role of a bridge connector, is to achieve the technical path of the world's interconnection. Just in the upstream of the industry chain, the connector companies have always been just heroes behind the scenes, rarely exposed, so it is not familiar to end consumers. As the world's largest connector manufacturer, TE is the "invisible giant" of the name, almost all the electricity, signals, data flow where it has a figure. If the whole business sector as the basis, every day there are new products, from the automotive industry, sensing technology, to the industrial field of contactless applications, or mobile terminals, ultra-small antennas, business scope covers almost all countries from consumer, transportation, energy, industry and all other fields. When the Internet of Things and Industry 4.0 become the new market engine, TE is a component manufacturer with more and more responsibilities. In James's view, the core of these market hotspots is simply the word "connectivity", connectivity between cars, connectivity between household appliances, and connectivity between security facilities, including in industrial applications, the connection between equipment. Only the requirements for connectors are becoming more and more demanding. The future requirements of the connector is nothing but faster, smaller, smarter and more environmentally friendly. But each segment has a different focus, James said, for example, like the automotive industry needs to ensure the reliability and high quality of connectors in harsh environments, for the consumer electronics industry, thin and light is the most important, followed by reliability, but the reliability of the two is not a level. The speed of consumer electronics pushing the new to a certain extent and determi

RJ45 network connector PIN pin contact resistance and reliability of the 4 major factors

RJ45 network connector PIN pin contact resistance is mainly affected by the contact part material, vertical pressure, surface form, the use of voltage and current and other factors. 1, the contact material Network connector technical conditions for different materials made of the same specification plug-in contact parts, the provisions of different contact resistance assessment indicators. Fast separation of the general specifications of environmental resistance electrical connectors GJB101-86, the diameter of 1mm mating contact parts contact resistance, copper alloy ≤ 5mΩ, iron alloy ≤ 15mΩ. 2, the surface vertical pressure of the contact surface The surface vertical pressure of the contact parts is the force generated by the surfaces in contact with each other and perpendicular to the contact surface. With the increase of vertical pressure, the number and area of contact microdots also gradually increase, while the contact microdots from elastic deformation to plastic deformation transition. The contact resistance decreases due to the gradual decrease of the concentration resistance. The positive contact pressure mainly depends on the geometry and material properties of the contact parts. 3.Surface morphology Surface morphology includes the shape of the design and the environmental state in which the contact surface may be due to dust, rosin, oil and other mechanical adhesion deposition on the surface of the contact formed by a looser surface film, this surface film with particulate matter is very easy to embed in the microscopic pits of the contact surface, so that the contact area is reduced, the contact resistance increase

For the first time in history, Chinese scientists successfully achieved counterfactual quantum communication

Compared with the traditional methods of communication, quantum communication with high security as the future direction of communications development, often reported quantum communications are based on the principle of entanglement, today to introduce a more weird form - Anti-Fictitious Communication: There is no quantum communication between two recipients for the quantum communication. The effect of not sending the quantum state of the particle transmission is also called the quantum Zeno effect. According to a recent report by the Physiotherapist Organization Network, researchers at China University of Technology successfully implemented direct counter-factual quantum communication, transmitting a black-and-white bitmap from one location to another without sending any physical particles, For the first time. The research was designed and experimented by the cooperation between China University of Science and Technology Shanghai Branch and Hefei Branch and Tsinghua University Chinese scientists, and successfully implemented counterfactual communication with a nested quantum Zeno effect. Quantum Zeno effect occurs in unstable quantum systems that are repeatedly measured. In the quantum world, observing or measuring systems can cause changes in the system. In this case, unstable particles will never decay when observed repeatedly. The quantum Zeno effect creates a virtually frozen system with a high probability. The study was published in the Proceedings of the National Academy of Sciences.
