Connection Characteristics And Process Principles of Terminal Blocks

During the entire assembly process, the Terminal Block Connector must withstand the high temperature of the preheating zone and the temperature conducted to the terminal body through wave soldering. The flux must not affect the terminal, it must be easy to remove, and there must be no residue.

The entire assembly process must be washable with water. The preheating temperature often reaches 100°C or higher, and it is not uncommon for the wave peak temperature to reach 280°C. The perforated solder pins must be accurately positioned, properly sized, balanced, and have good performance Solderability, which is conducive to insertion and welding. During the entire assembly process, it must withstand the high temperature impact caused by heat treatment. In the welding process, infrared preheating and convection preheating are mainly used to conduct heat to the interface of the solder pin and the tin plate to melt the solder. Paste. Contacts have poor resistance to welding. When the motor is started or the circuit is short-circuited, the high current will cause the contacts to be welded firmly and cannot be released. Among them, the pure silver contacts are easier to weld. The main contacts of the AC contactor should be resistant to welding. Silver-based alloys with strong welding ability, such as silver iron, silver nickel, etc.

Terminal Block Connector

In the optical fiber communication link, in order to realize the needs of flexible connection between different modules, equipment and systems, there must be a device that can be detachably connected between the optical fiber and the optical fiber, so that the optical path can be carried out according to the required channel. Transmission, in order to achieve and complete the predetermined or expected purpose and requirements, the device that can achieve this function is called the Busbar Connector. The terminal is to precisely connect the two end faces of the optical fiber to maximize the light energy output by the transmitting fiber Coupling to the receiving fiber to the limit and minimizing the impact on the system due to its intervention in the optical link is the basic requirement of optical fiber connectors.

The terminal has good connection characteristics even when the temperature fluctuates greatly. Because this can avoid different degrees of thermal expansion due to the difference in the thermal expansion coefficient of the material, it can also avoid mechanical stress in the Brass Terminal and avoid loosening of the connection. .Using the "Reakdyn principle" to prevent the terminal screws from loosening. In the preferred terminal series with a rated cross-section of 10mm2, the crimping frame adopts a lifting barrel structure. Their principle of action is based on the so-called "lifting barrel principle". The continuous improvement of circuit board technology has greatly increased the current that the terminal installed on the panel can carry.
