[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 1 to 6 As shown, a card holder of an optical fiber connector includes:

[0024] The fixing seat 1 is used to fix two separate LC-type optical fiber connectors 2 and provide a pair of contact interfaces for power transmission. The fixing seat 1 is provided with an electrical transmission interface and a connector holder. The fixing seat 1 can be divided into two plane parts in terms of function and area. The electrical transmission interface on the first plane is used to set conductive contacts, etc., and the connector holder on the second plane is used to fix the optical fiber connector.

[0025] On the first plane, the front part of the fixing seat 1 has two extensions 3, at least a part of the conductive sheet accommodating cavity 4 is located in the extension 3, the two conductive sheet accommodating cavities 4 or the extension 3 are located on the first plane and arranged in parallel, and the open window 5 is arranged on the extension 3. The open window 5 is arranged on the adjacent surface of the two extensions 3, that is, on the inner side surface between the two extensions 3. The rear part of the fixing seat is provided with a terminal accommodating cavity 6, and the terminal accommodating cavity 6 is used to arrange the wiring terminal 7. The conductive sheet 8 is arranged in the conductive sheet accommodating cavity 4 and extends to the wiring terminal 7 in the terminal accommodating cavity 6, and is electrically connected with the wiring terminal. The front end of the conductive sheet 8 is provided with a bending portion to form a spring structure, which is convenient for stably realizing the electrical connector.

[0026] The terminal block 7 can adopt the structure of the prior art, as long as it can quickly realize electrical connection with the wire, for example, it can adopt a threaded terminal or a bayonet terminal. Taking the threaded terminal as an example, the bolt port of the terminal block 7 can be set on the bottom surface of the fixing seat 1, and the rear end cover 9 of the terminal accommodating cavity 6 is provided with an insertion port 10, and the insertion port is used to allow the external wire to enter the terminal block 7 from the tail end. The tail end of the conductive sheet 8 can be mounted on the bolt, and when the bolt is tightened, the tail of the conductive sheet 8 is squeezed until the wire and the conductive sheet 8 are squeezed and fixed together. After the wire is fixed to the terminal block 7 by the bolt, the wire and the conductive sheet 8 are electrically connected.

[0027] On the second plane, the connector holder is configured to have two slots 11, which correspond to the conductive sheet accommodating cavity 4, and the slots 11 are used to fix the optical fiber connector. The two slots 11 are located on the second plane and are arranged in parallel. The walls on both sides of the slot 11 are provided with through openings 12, and the through openings 12 are used to allow the optical cable of the optical fiber connector to move laterally from the outside into the slot 11. A card block 13 is provided on the inner wall of the slot 11, and the card block 13 can be snapped onto the bayonet 14 of the optical fiber connector to fix the optical fiber connector on the fixing seat 1. A pressure plate 15 is provided on the outer surface of the slot 11 for cooperating with the locking piece of the optical fiber connector that cooperates with the adapter. The locking piece of the LC type optical fiber connector is an elastic arm structure 18, and the pressure plate 15 presses the elastic arm structure 18 at the same time, so as to pull the optical fiber connector out of the adapter.

[0028] The connector used in this patent can be a field-assembled optical fiber connector of the prior art, or a factory-prefabricated optical fiber connector of the prior art. The field-assembled optical fiber connector generally includes a clamp spring 16 and a cover plate 17, and the cover plate 17 is pressed by the clamp spring 16 to fix the optical fiber on the connector. The factory-prefabricated optical fiber connector, that is, the optical cable is already fixed in the connector.

[0029] When in use, the cable of the optoelectronic hybrid cable is stripped to expose the conductive core, the conductive core is inserted into the wiring terminal 7 of the fixing seat 1, and the wiring terminal 7 is fixed to the conductive core to form an electrical connection. For the field-assembled optical fiber connector, the optical fiber is fixed on the LC type optical fiber connector to form an optical fiber connector, and for the factory prefabricated type, it is directly in the form of a connector. At this time, the main body of the connector is placed in front of the fixing seat 1, the optical cable is pressed into the card slot 11 from the through port 12, and then the connector is pushed backward into the card slot 11, and the connector is fixed on the fixing seat 1, thereby forming a dual-core LC type optoelectronic hybrid connector.
