本发明涉及一种电光转换连接器组件。The invention relates to an electrical-optical conversion connector assembly.
背景技术Background technique
采用光信号传输高数字信号是目前信号传输的发展趋势，因此就需要能将电信号转换为光信号的电光转换装置来实现电信号与光信号之间的转换，目前的电光转换装置如图1所示：包括用于设置于相应设备的机箱面板103上的连接器102和用于设置于设备内部的电光转换模块105，电光转换模块设置于设备内部的用户印制板106上，电光转换模块的电信号输入端与用户印制板上的电路相连，电光转换模块的光信号输出端通过光缆104与连接器相连。图项101表示与连接器102适配的光插头。现有的这种电光转换装置存在的问题在于：电光转换模块需要占据用户印制板的布板空间，电光转换模块属于发热元件，需要考虑电光转换模块的散热问题，给高速信号的光电转换应用带来一定的困难，同时还需要在连接器与电光转换模块之间设置光缆，光缆不像电缆一样可以随意弯折，由于设备内部的本身空间就非常有限，光缆在设备内部布线过程中非常容易折断，对于空间要求紧凑的机箱设备，机箱内光缆的布线实现较为困难；电光转换模块无法采用回流焊，需要在印制板贴片完成后采用手工焊接的形式将电光转换模块焊接到印制板上，增加了电光转换模块的使用难度，同时焊接可靠性也不高。The use of optical signals to transmit high-level digital signals is the current development trend of signal transmission. Therefore, an electro-optical conversion device that can convert electrical signals into optical signals is needed to realize the conversion between electrical signals and optical signals. The current electro-optic conversion device is shown in Figure 1. As shown: it includes a connector 102 for setting on the chassis panel 103 of the corresponding device and an electro-optical conversion module 105 for setting inside the device. The electro-optic conversion module is set on the user printed board 106 inside the device. The electro-optic conversion module The electrical signal input end of the electrical signal is connected to the circuit on the user's printed board, and the optical signal output end of the electro-optical conversion module is connected to the connector through the optical cable 104 . Item 101 represents an optical plug mated with connector 102 . The problem with the existing electro-optical conversion device is that the electro-optic conversion module needs to occupy the layout space of the user's printed board, and the electro-optical conversion module is a heating element, so the heat dissipation of the electro-optical conversion module needs to be considered, and the application of photoelectric conversion for high-speed signals It brings certain difficulties, and at the same time, it is necessary to install an optical cable between the connector and the electro-optical conversion module. Unlike the cable, the optical cable can be bent at will. Since the space inside the device itself is very limited, it is very easy to route the optical cable inside the device. For the chassis equipment with compact space requirements, it is difficult to realize the wiring of the optical cable in the chassis; the electro-optical conversion module cannot be reflow soldered, and the electro-optical conversion module needs to be welded to the printed board by manual welding after the printed board is mounted. On the other hand, it increases the difficulty of using the electro-optical conversion module, and the reliability of welding is not high at the same time.
