Production Process And Crimping Inspection Of Cold-pressed Terminals
The so-called cold end, in fact, when used, the thread of the wiring electronic components usually used is the cold terminal crimping method, and the crimping tool and other related tools will be used. Since the method is not welded, there is no heat treatment, but the infusion of molten tin and there are different methods, so we call it a terminal block for cold terminal blocks.
Cable Lugs has differences in copper and aluminum, closed and open through the relationship between product development. It is often used in the joints of Chinese power and cables. At present, in addition to the terminal block of the PCB board, there is also a nut terminal block, a continuous terminal block of hardware, and a spring terminal block. The main production technology process of this product in China is stamping, and then it will be processed on its research surface according to the requirements of students. Electroplating Au/Tin.
However, the key point of application in actual production lies in the material, so when manufacturing cold stamping terminal products in the production technology of the enterprise, it is recommended to choose red copper material with good plasticity and very high conductivity. In order to ensure the quality of the company's products, crimping inspection is also necessary. The specific operation management method is as follows.
The first is to combine the cross-sectional requirements of the wire to be used, and select the appropriate cold-pressed terminal products. At this time, it is necessary to ensure that the corresponding specifications are consistent. Secondly, whether the length of the stripped conductor insulation layer meets the correct requirements of the length requirements. In addition, all the wires of the conductor are completely enclosed in the cold-pressed terminal, and there is no need to spread the copper wire. At the same time, the crimping part meets the specification requirements and the crimping part must be correct. In addition, according to the strength requirements of the tensile strength test in the TB/T1507-93 standard, the crimping joint was tested for strength. The quality of the crimping joint was inspected by a calibrated TLS-S2000A spring tension and compression testing machine.
In addition to the above, when the crimping tool is crimped in the test terminal, the crimping tool should meet the associated fixing strength requirements. The test is verified once every three months to meet the requirements of the tool. The use should have a display cycle, in which the inner label. 400~500 mm bundling wire at least once when bundling wire.
