Terminal can be roughly divided into: plug terminal series, european-style terminal series, the series of fence type terminal blocks,Spring terminal series, rail terminal series, wear wall type terminal series and so on.In a lot of equipment, often need to connect terminals, through the connection, you can have the effect of transmission, especiallyIt is in the electric field, is particularly important to the terminal, can realize remote connections, such as network, TV, telephone, distanceEverything from the transmission using terminal blocks to connect to.As a kind of connector, terminal is an important component in the electrical industry, plays an irreplaceable, can not be ignoredTo use.Engineers in selecting terminal, be sure to carefully selected for their terminal products, to ensure that the product is Often work.

October 15, 2017 to October 19 electrical exhibition to attend the Canton fair, our booth no. : 11.3 L06, welcome new and old customers to visit our booth at the appointed time.

One of the first factors to consider is the power handling capability of the device. Simply reading the data book does not guarantee accurate comparison data. Engineers must understand how the product performance data listed in the manual is tested and determined. Currently, organizations such as UL, IEC, CSA and DIN do not have uniform standards in determining the power and performance specifications of terminal products. Users need to understand the differences between UL and IEC specifications. Terminals manufactured in Europe are subject to the IEC standard, while products manufactured in the U. S. adopt the UL standard. The difference between the two standards is very large. Engineers who do not know the product specifications will risk considerable risk because the selected devices may not meet the required power levels, or the specifications of the devices are well beyond the design requirements. In Europe, the current rating of a device is determined by monitoring the temperature of the metal conductor when the current increases. When the temperature of the metal pin is 45 degrees higher than the ambient temperature, the measuring staff will use the current as the rated current value (or maximum current value) of the device. The other item in the IEC specification is to allow current value, which is 80% of the maximum current. In contrast, the UL standard will make the metal conductor temperature higher than the ambient temperature by 30 degrees centigrade, and the current value of 90% will be the current nominal value of the device. Thus, the temperature of the metal conductor part is a very important factor in all applications. This is even more important for industrial equipment. Because industrial equipment usually needs to work at temperatures up to 80 degrees celsius. If the temperature of the terminal is 30 degrees or 45 degrees higher than the temperature, the temperature of the terminal will be over 100 degrees centigrade. According to the nominal value type and insulation material adopted by the selected device, the product must work at a current lower than the rated value so as to ensure that they can work reliably in the desired temperature range. Sometimes, materials suitable for compact packaging devices may not be well suited for thermal dissipation, so the current used by such terminals must be much lower than the rated value.

Terminal material nylon (PA66), where V0 flame retardant grade, at the same time, do not contain any harmful halogen, flame retardant performance is superior, safe, environmental protection.Other commonly used materials and thermoplastic polyester (PBT), and to cope with perforated reflux technology and use of liquid crystal polymer (LCP). Function theory: When the motor overload, input more current than the rated current of electrical, thermal relay the heat element will due to excessive current flows through the fever.Cause bending.Through the mechanical structure of the internal drive the output switch contact.Achieve the goal of "overload" output.Auxiliary contact of "NC" contact group can series in the control circuit of power lines (with "stop" button series), once the motor overload, the auxiliary contact "NC" contactor will cut off the control circuit of power supply, make the machine stop running.Auxiliary contact of the "NO" contact group can pick up alarm device (e.g., alarm indicator light), once the motor due to overload and stop operation, gives the cause of the motor to stop - "overload". Help contact terminal: Terminal heat element, usually by the thermal expansion coefficient of different metal materials.Double thermal element if heated metal materials, because of the different expansion coefficient, bending will occur.Work when the hot components in series in the main loop of the circuit (such as motor starter motor power supply circuit in).Up and down two rows of each have three terminals, each hot components connect between the two terminals on a, a total of three components, respectively in series in article 3 of the motor power input line.The auxiliary contact, usually a normally open (NO), a normally closed (NC) contact.Used for the starter motor control circuit.

Terminals of the welding conditions have strict requirements and professional standards, the material, specification, welding way through strictly controlled. Shenzhen jet electronic as a famous domestic terminal manufacturer, here to give you the most professional answer. There is significant difference between the welding conditions, depending on the type of terminal blocks and welding process steps.Suitable for wave soldering, installed on the PCB terminals is a typical punch installation type.Perforation of welding pin must be accurate positioning, suitable size, balanced placement, and has good weldability, conducive to insert and welding. In the process of the whole assembly, must withstand preheating zone, high temperature and wave soldering to the terminal body temperature.Flux may not affect terminal, must be easy to remove, there cannot be any residue.The whole assembly process must be clean with water.Preheat temperature often up to 100 ° C or higher, peak temperature of 280 ° C is also not uncommon. Perforation of welding pin must be accurate positioning, suitable size, balanced placement, and has good weldability, conducive to insert and welding.In the process of the whole assembly must withstand high temperature shock produced by heat treatment, mainly used in welding ir preheat preheat and convection heat conduction to welding needle and tin interface with molten solder paste. The sudden high temperature melt terminal, often distorted, blister and deformation.General component is so assembly time, a few minutes of exposure to the flux of time, a few minutes of preheating period, and the peaks of a few seconds, and cleaning and drying period of a few minutes.Choosing the right metal materials, resin can improve the reliability of terminal welding.

Terminal belongs to the electronic information industry in the middle of the products, the most direct contact of the product is connector, its development speed, reached the technical level and the scale of production, not only directly influences the whole electronic information industry development, also affect the development of the connector, and the development of information technology to transform traditional industries, improve the level of modern equipment, promote the progress of science and technology has profound influence. At present through Chinese alliance group statistical data terminals, terminal blocks of the most serious product homogeneity area mainly concentrated in Asian developing countries, China is most obvious, careful analysis, terminal "metamorphic" the main reason is the terminal agent with the interests of the client terminal. Technical substitution advantage, and directly imitate technology research and development of large terminal manufacturers, saving product research and development funds.China is a technology patent protection system is the most weak countries, large terminal manufacturers and the lack of patent protection consciousness, lead to a large number of fake products, product market competition is severe, large terminals manufacturers interest weakened.Mixed product authenticity, at present, the part of the small terminal under the profit-driven agent manufacturers, terminal product of the agent authenticity, cheating the customer terminal demand, at the same time reduces the agent of the brand image. The company's view: the mature terminal product innovation path is not a simple imitation, stealing, compression cost to improve the chances of price war victory, and how to crush the competition for the other side of the market share.Because of complicated face a terminal market, terminal enterprises need to launch new products or new services more quickly in response to a severe attack of the competitors.At the same time, the terminal customers also need long term problems, don't cry because it is a simple product price mistake lead to unnecessary consequences later.

Copper terminals is connected with a power transmission terminal, including aluminum terminal ontology, the terminal ontology for at the end of the round tube, the other end is flat, at the side of the flat part of the terminal ontology with copper layer on the surface, the flat parts of the copper layer and the corresponding to fusion for one-piece structure without solder connection.Copper terminals in distribution equipment apply to all kinds of circular, semi-circular the transitional connection on aluminum alloy copper cables and electrical equipment.Copper terminals with friction welding craft manufacture, high weld strength, good electric performance, electrochemical corrosion resistance, long service life.Can be realized in different space and Angle of installation, improve the working efficiency, reduces the labor intensity.Effectively reduce terminal and wire connection caused by Angle of friction, reduces the equipment accidents. Copper terminals to note: 1. The selection of terminal blocks, hardware, avoid cable in operation of problems because of substandard 2. The installation process to operate strictly according to the installation process 3. The reasonable distribution of power load, the establishment of regular load measurement system, a reasonable allocation of three-phase load, achieve the safety of the electricity.

No matter what product in the use of problems involved in the product in addition to the necessary performance is the strength of the product and service life.And the intensity of products is especially important in the plastic products, such as terminals, nylon cable tie, line card, cable joint, etc. Products, directly affect the strength of the product scope of use and the environment, better the strength of the product can be applied to a wider range of areas, helps to develop a broader market. Terminal is mainly composed of two parts, part insulators and conductors, and insulation parts are usually made with plastic material production, so the strength of the plastic material directly affects the overall performance of the product.And the terminal in the market at present basically has nylon, polyethylene, polypropylene, polyethylene carbon, bakelite, and so on material production, and some use copper conductor is the most widely used and accepted in the market at present material, copper material, of course, more favored by customers.And in certain circumstances, also can use zinc alloy as the conductor material. And the intensity of terminal product mainly is decided by two parts, production material and production process.Material in a particular industry has certain rules, the material of use does not conform to the stipulations of the industry will lead to product performance is not up to standard.Of course, we can also use the better material performance, is the product performance and strength is higher than the industry standard.And the production technology is another element that affects product strength.The high quality production technology can make the products have higher strength.Based products production and material decided the same intensity, and the intensity of usage is also affecting the product of external factors.UK series terminal, for example, used alone a use the electric screwdriver wiring terminals fixed on the guide rail, so often the strength of the product, but on a group of products installed, using a fixed pieces and other auxiliary parts assembled using electric screwdriver connection strength of its products will be higher.External cause, of course, also including the use of the environment, such as terminal under the environment of high temperature plastic casing strength will reduce, the same product performance will decline in acid and alkali environment. The second is the product of conductor performance, the performance of the conductor in conductivity and deformation.Conductor is usually copper terminals series products.And the conductivity of copper is very good, but the bronze number is different, its conductivity.Deformation problem exists mainly in high purity usually, due to the quality of a material soft copper, so copper content is lower and the higher the product of the strength.In general, high quality plastic insulator and the high quality copper determines the quality and strength of the terminal. Terminal belongs to the electronic information industry in the middle of the products, the most direct link product is connector, its development speed, reached the technical level and the scale of production, not only directly affects the development of the electronic information industry, also affect the development of the connector, and the development of information technology to transform traditional industries, improve the level of modern equipment, promote the progress of science and technology has profound influence. The terminals of the most serious product homogeneity area mainly concentrated in Asian developing countries, China is most obvious, careful analysis, terminal "metamorphic" the main reason is the terminal agent with the interests of the client terminal.

Terminals in Europe use IEC standard product specifications and products manufactured in the United States and manufactured using UL standards. At present, the UL certification, IEC, CSA and DIN terminals and other institutions to determine the power and performance of product specifications, and there is no uniform standard. Users must understand the differences between the ULIEC standards. Requirements of product standardization, let go advocate early stage, the design of the final draft of the scene is still in the market to start brewing, the growth stage of preparation. Terminals must be comfortable on-site installation, as they are usually installed in a clearly visible front panel product. As a result, marketers tend to have some say in the appearance of power wiring terminals. Often meet the building terminals this situation: engineers design products to meet all mechanical and electrical parameters requirements, but also because the application does not meet the sales changes. Company tenet: same quality than price, same price than quality!
