技术领域technical field
本实用新型涉及一种电源适配器。The utility model relates to a power adapter.
背景技术Background technique
电源适配器是小型便携式电子设备及电子电器的供电电源变换设备，一般包括壳体，及设置在壳体内的PCB板，及与PCB板一端连接的至少二个插脚，及与PCB板另一端连接的至少二个导脚。目前的电源适配器，大多采用把插脚直接注塑成型连接在适配器壳体上，再将PCB板安装到壳体内，使PCB板上的铜片与插脚接触，然而，该种安装方法效率比较低，铜片易与插脚接触不良；且插脚与适配器注塑成型时，插脚垂直于适配器壳体设置也使得适配器外形结构尺寸较大、笨重，在包装和运输上非常不方便。另，由于在PCB板上没有设置保险管，当出现异常电压时，容易烧坏电源适配器，更严重时会引起火灾，造成很大的安全隐患。The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It generally includes a housing, a PCB board installed in the housing, and at least two pins connected to one end of the PCB board, and a pin connected to the other end of the PCB board. At least two guide pins. Most of the current power adapters use direct injection molding to connect the pins to the adapter housing, and then install the PCB board into the housing so that the copper on the PCB board contacts the pins. However, this installation method is relatively inefficient. The pins are easy to be in poor contact with the pins; and when the pins and the adapter are injection molded, the pins are arranged perpendicular to the adapter shell, which also makes the adapter's external structure large and heavy, which is very inconvenient in packaging and transportation. In addition, since no fuse is provided on the PCB, when an abnormal voltage occurs, the power adapter is easily burnt out, and in a more serious case, a fire may be caused, resulting in a great potential safety hazard.
