Description

Photoelectric hybrid connector and use method thereof Technical Field The invention relates to the technical field of optical communication, in particular to a photoelectric hybrid connector and a use method thereof. Background The optical fiber communication mode is a communication mode which uses light waves as an information carrier and uses optical fibers as a transmission medium. Devices such as connectors, optical modules, adapters and the like are generally involved in the field of optical communication technology. The optical module is used as an important optical signal interface device in optical fiber communication and is provided with an optical interface and an electric interface, the optical interface is connected with the optical fiber to transmit optical signals, the electric interface is connected with external communication terminal equipment, and the adapter is used for switching the two connectors. Especially in the optical fiber equipment represented by 5G base station and FTTR equipment, the scene that needs the distal end power supply when the wide communication has exists a large amount of grafting photoelectric circuit, because the photoelectricity sets up and leads to the connector quantity to be many and divide into photoelectricity two types separately, need pair correctly one by one, lead to in installation maintenance in-process complex operation, and the condition of grafting error appears easily. On the other hand, in the scene that an optical fiber to the home (Fiber To The Home, abbreviated as FTTH) network uses the terminal end of the network, a traditional copper wire is used for transmitting network signals and simultaneously adding power to the terminal end, as the FTTH optical network is developed to a FTTR optical network, for example, a vehicle-mounted terminal needs to meet the requirements of automatic driving and artificial intelligent interaction, the bandwidth of the terminal end is required to be higher and higher, the traditional copper wire signal transmission capability cannot meet the bandwidth requirement of the terminal end, FTTR uses the copper of the terminal end signal transmission medium of the network to carry out the light withdrawal, the power of the terminal end is provided by a cable, and the situation is promoted, and in order to connect the compound cables, one solution in the prior art is that an optical connector and an electric connector are independently designed, the optical connector and the optical adapter are in plug-in coupling to realize the butt joint of optical signals, and the electric connector and the electric adapter are in plug-in coupling to realize the butt joint of electric signals. But using separate optical and electrical connectors requires two plugs to complete the connection with the adapter. The photoelectric hybrid connector and the photoelectric hybrid adapter are adopted, but in some existing schemes, the electric terminal part of the connector is exposed outside, a certain potential shock hazard exists in the actual use process, the human-based safety problem exists, and other schemes adopt clamping jaw type terminals, so that the problems of large occupied space, large friction force, low coupling reliability of the electric terminal, insufficient through-current capability and the like exist. In addition, the optical fibers of the optical fiber connector need micron-level butting precision, any stress in the non-optical axis direction can influence the optical fiber coupling efficiency and the optical fiber coupling precision in the coupling butting process, the existing electric terminals are arranged in an asymmetric mode on the optical fiber coupling structure distribution, the friction force is increased when the connector is plugged and unplugged due to asymmetric arrangement, plugging stress is formed in the plugging and unplugging process of the electric terminals, and the coupling precision of the optical channels of the connector is influenced. And current positive end electric terminal and female end electric terminal adopt many bullet needle structures of parallel, occupation space is big and consume the material many, in the vibrations scene, the contact of positive end electric terminal and female end electric terminal can't be guaranteed to parallel structure, therefore can't guarantee the reliability of electric coupling under the vibrations scene. In view of this, overcoming the drawbacks of the prior art is a problem to be solved in the art. Disclosure of Invention The invention aims to solve the technical problems that the optical fiber coupling efficiency and the coupling precision are lower and the coupling reliability of the electric terminals is insufficient because the electric terminals of the existing photoelectric hybrid connector and the photoelectric hybrid adapter are asymmetric in the distribution of the optical fiber coupling structure. The invention adopts the following technical s
