The market for the connector miniaturization trend of centralization and the need to promote technological innovation terminals. Semiconductor chip technology is becoming the driving force interconnect technology at all levels of development of the connector, for example, with 0.5mm pitch to 0.25mm pitch chip package rapid development, so I level interconnect (IC device internal) and Ⅱ Interconnect (Device device pin count and board interconnect) line by hundreds of thousands of lines. In the cylindrical slotted jack, flexible wire pins and double curved wire spring socket connector commonly used in press fit contact technology, greatly improving the reliability of cold terminal connector tube, ensuring the signal transfer The fidelity. The connector terminals technology constitutes a new cold terminal connector products that push-in connector, which is mainly used for system-level interconnect, its biggest advantage is no cable, installation and removal simple and easy field replacement, and mating fast, smooth and stable separation of 250 cold terminal, get a good high-frequency characteristics for spacecraft. Connector assembly technologies are surface mount technology developed by the plug-in installation technology, and the future trend is towards the development of micro-assembly techniques, the use of micro-electromechanical systems will increase the connector technology and cost-effective power. Mechanical Testing torque test (Tightening Torque Test) The purpose of the test is to test the screw torque if there is sufficient mechanical strength to ensure that the phenomenon does not occur in the course of slide wire pressure line, if the screw is not broken after the test, deformation, screw head slots are not damaged, affecting continue to use, it is acceptable. 2. Crimping reliability test (Secureness TeST) pressure line reliability test purpose is to test whether the terminal to clamp the wire but not excessive damage to the conductor. Terminal connected to the specified type and rated cross-sectional area of ??the wire, hang some weight to 10 revolutions per minute ((1012r / min) speed of rotation, continuous 15min after the test, if the conductor does not slide clamp terminals there is no break in the vicinity of the clamping member, the terminal crimping reliability is acceptable. If there is a wire break or fall off the terminal clamping mechanism, it is unqualified. 3, drawing test (Pull Out Test) The purpose of the test is to pull the test terminals can be firmly clamped between the metal wire surface. terminal access specified type and rated cross-sectional area of ??the wire, the choice of a certain force ((lkgf), will lead toward the axial direction of the wire Pull keep 1mine If the wire does not fall out of the terminal, it is qualified. cold terminal wholesale, cold terminal, Chong Xu Song Electronic Products Factory Dongguan Shijie by Xu Song Chong electronic products factory provided.
