The invention provides a device and a method for testing short circuit and open circuit of a flexible flat cable (FFC). The device comprises a bottom plate and a test device body which is positioned on the bottom plate, wherein a light-emitting diode (LED) indicating lamp is arranged above the test device body; left and right probes are arranged above the bottom plate and in front of the test device body; a set of sliding sleeves and guide posts is arranged at a connection part of the left and right probes and the test device body; and a buzzer is also arranged on the bottom plate. In the invention, the short circuit and open circuit tests of the FFC are realized by testing the left and right probes, the indicating lamp and the buzzer on the device, so that the electric performance of theFFC is guaranteed; meanwhile, the coiled FFC prior to being sliced can be tested, so that test efficiency is improved to a large extent relative to each piece of individual test.
Description
technical field [0001] The invention relates to the field of flexible cables, in particular to a short-circuit and open-circuit test device and method for flexible cables. Background technique [0002] Flexible Flat Cable (FFC) is a component for signal transmission. It has the advantages of arbitrary winding and high signal transmission, so it is widely used in many electronic products. The flexible cable is used in conjunction with an electronic connector to transmit signals from one end to the other to achieve the purpose of signal transmission. [0003] The electrical performance test of the existing flexible cable is generally performed by manual short-circuit and open-circuit tests on the flexible cable, and each pcs can only be tested individually. To a certain extent, it not only increases the labor cost, but also reduces the testing efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a flexible cable short circuit an...
