Recognition may be one or more of the specific recognition device terminals and wire terminals: a, using related products marking system to identify and actual or relative position recognition device terminals or specific wire line terminals; b, using related products marking system to identify and recognize the device terminals and specific color-coded wire terminals; c, using graphic symbols GB5465 stipulated. For the use of auxiliary symbols, should be consistent with the GB4728 graphics; d, using the alphanumeric symbols of the standard set forth in Section 5. Test terminals switch from the role of the sliding metal frame through the terminal can withstand the maximum pressure operating current, loosen the screw terminal PCB board with a screwdriver wholesale switching, move the slider on the line, the switch position becomes clear; it ends with a test sockets, equipped with the appropriate test ends can test the connection, measuring current without interrupting operations. Can be connected to 660V voltage control loop current is 57A. Electronic cable is connected to the electrical circuit of one of the components PCB board end (B1611), mainly between the device and the components, assemblies and cabinets, systems and subsystems from the electrical connection and signal transmission effect, and ensure that the system and the system conversion between the signal distortion and energy loss does not occur letter PCB board sell-side businesses, the quality of the quality of equipment related to the reliability of the system as a whole operates. Belonging to the host companies an important accessory products, its technical characteristics by technical development of downstream industry influence. With the consumer electronics, automotive electronics, fast-growing markets and global communication terminal connector production capacity continues to shift to Asia and China, Asia has become the connector market, where the most potential, and China will become the world's fastest-growing connector and the capacity of the largest markets. The main supporting areas of the connector have transportation, communications, networking, IT, medical, home appliances and other PCB board side, the rapid growth of the rapid development of products supporting the field of technology and markets, a strong traction with connector technology development, So far, the connector has developed into a complete product range, variety of specifications, structure forms, professional direction subdivision, industry characteristics significantly, the standard system standard series and specialized products. Connector product development has the following characteristics: high-speed information transmission and digitization, all kinds of information transmission of the integration, product miniaturization of small volume, low cost products, contact end street style surface mount technology, module combination , the convenience of plug ......
