Technical Field

[0002] An electrical connector is a conductive device used to fix and electrically connect at least two wires. Figure 1-3 As shown, the conductive devices currently on the market for fixing and electrically connecting the connecting wire and the enameled wire mainly include a first conductive terminal A and a second conductive terminal B. The first conductive terminal A is used to fix and electrically connect to the connecting wire, and the second conductive terminal B is used to be inserted into the plastic shell and pierce the enameled wire to contact and conduct electricity with the enameled wire. Subsequently, the first conductive terminal A and the second conductive terminal B need to be plugged in to achieve electrical connection between the connecting wire and the enameled wire. However, in the existing conductive device structure, since the first conductive terminal A and the second conductive terminal B are split structures, the first conductive terminal A is likely to be separated from the second conductive terminal B after the first conductive terminal A and the second conductive terminal B are plugged in, that is, there is a disadvantage of poor connection reliability between the first conductive terminal A and the second conductive terminal B. In addition, there is also a disadvantage of a complex connection structure between the first conductive terminal A and the second conductive terminal B. Utility Model Content
