Abstract: The transformer has a bobbin, a coil assembly and a magnetic core assembly. The bobbin is mounted in the magnetic core assembly and has multiple connecting pins being formed on at least one side of a bottom surface of the bobbin. Each connecting pin has a top surface as a soldering surface that corresponds to a solder pad on a back of a circuit board. At least one fastener is further formed on the bottom surface of the circuit board. Therefore, when the transformer is mounted through the circuit board, the connecting pins are soldered on the back of the circuit board to reduce the total thickness of the combination of the transformer and the circuit board.

Abstract translation: 变压器具有线轴，线圈组件和磁芯组件。 线轴安装在磁芯组件中，并且在筒管的底表面的至少一侧上形成有多个连接销。 每个连接销具有作为焊接表面的顶表面，其对应于电路板背面上的焊盘。 至少一个紧固件进一步形成在电路板的底表面上。 因此，当变压器通过电路板安装时，连接引脚焊接在电路板背面，以减小变压器和电路板组合的总厚度。

Abstract: The invention relates to an optical output system with auto optical power control for an optical mouse. The optical output system comprises: a light emitting device, a driver and an auto power controller. The light emitting device is used for generating emitting light. The driver is used for driving the light emitting device. The auto power controller is used for outputting a control signal to the driver according to at least one input signals so as to control the power of the light emitting device at a predetermined range. According to the invention, the optical output system can output the stable power of the emitting light at a predetermined value within the predetermined range under various conduction and circumference by a feedback control. Furthermore, the optical mouse using the optical output system can work on various reflective surface.
