Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 and Fig. 9 , which is the first embodiment of the present invention, provides a flange connector based on FC optical fiber, which provides an intuitive on-site indication reference when the patch fiber is not properly connected, the thread is not tightened, or an unmatched patch fiber is used for connection, so as to solve the problem that the commonly used FC / FC flange connector in the existing power system does not have the pigtail access coupling quality detection, thereby affecting the stable operation of the communication system.

[0033] Specifically, it includes a docking component 100, a circuit component 200 and a protection component 300, wherein the docking component 100 is used to dock with the FC optical fiber connector, the circuit component 200 can judge the quality of the pigtail access according to the circuit on-off condition, and the protection component 300 performs insulation protection to isolate weak electricity to prevent operators from electric shock.

[0034] Furthermore, the docking assembly 100 includes a docking base 101 and a core sleeve 102. The docking base 101 is made of metal material and is conductive. The docking base 101 has a core hole 101a that is sufficient for the optical fiber to be inserted. The core sleeve 102 is arranged on both sides of the port of the docking base 101 corresponding to the core hole 101a. The core sleeve 102 has an external thread groove 102a that is adapted to the threaded connection mechanism on the FC optical fiber connector, and a positioning groove 102b that cooperates with the boss on the FC optical fiber connector.

[0035] Specifically, when the FC optical fiber is connected to the flange connector described in the present application, the end of the FC optical fiber connector is correspondingly inserted into the core hole 101a of the docking base 101; by providing the core sleeve 102, protection is provided for the FC optical fiber access, the access bending is reduced, and the axis of the optical fiber and the core hole 101a of the connector are ensured to be aligned, while preventing dust and impurities from entering the core hole 101a of the connector; specifically, the positioning groove 102b cooperates with the boss on the FC optical fiber connector to ensure sealing and play a dust-proof role; the external thread groove 102a on the outside of the core sleeve 102 cooperates with the threaded connection mechanism on the FC optical fiber connector to improve the reliability of docking and make the connection more stable.

[0036] Furthermore, the circuit assembly 200 includes an indicator light 201 and an elastic contact piece 202 connected in series. The elastic contact piece 202 has an active end 202c-1 that can be separated and combined with the docking base 101. The active end 202c-1 of the elastic contact piece 202 is a contact point for circuit connection, and its position should be adapted to the FC optical fiber connector. When the FC optical fiber is connected, it can be squeezed by the end of the FC optical fiber connector to contact the docking base 101, and after the FC optical fiber connector is separated, it can be separated from the docking base 101 through its own elastic recovery characteristics.

[0037] It is worth noting that the docking base 101 is made of metal material and has conductivity. In this embodiment, it is used as a part of the circuit and cooperates with the circuit component 200 to form a complete circuit for transmitting current.

[0038] Specifically, the movable end 202c-1 of the elastic contact piece 202 is squeezed when the FC optical fiber is connected, so that it contacts the docking base 101, and the elastic contact piece 202 is conductive. When the movable end 202c-1 of the elastic contact piece 202 contacts the docking base 101, the circuit is connected, and the indicator light 201 lights up. The staff can judge whether the FC optical fiber is correctly connected according to the on and off status of the indicator light 201, and judge the access quality of the FC optical fiber according to the brightness of the indicator light 201 or whether it flickers.

[0039] Example 2

[0040] Reference Figure 6 and Figure 7 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the elastic contact piece 202 includes a mounting portion 202a, a pushing portion 202c, and a bending portion 202b connected between the mounting portion 202a and the pushing portion 202c. The elastic contact piece 202 is integrally formed, or formed by multiple bending and cutting processes.

[0041] Specifically, the middle section of the mounting portion 202a has a bent section 202a-1 protruding toward one side, and the free end of the mounting portion 202a is hook-shaped; the free end of the pushing portion 202c is rolled, and the free end of the pushing portion 202c is a movable end 202c-1 for the elastic contact piece 202 to be separated and combined with the docking base 101; both sides of the end of the bending portion 202b respectively connected to the mounting portion 202a and the pushing portion 202c have inwardly narrowed waist grooves 202b-1, and the middle section of the bending portion 202b has a V-shaped cutout 202b-2.

[0042] Specifically, the design of the waisted notch 202b-1 and the V-shaped cutout 202b-2 can improve the flexibility and elasticity of the elastic contact piece 202, so that the elastic contact piece 202 can be better bent and reset when subjected to external force, thereby ensuring that the movable end 202c-1 of the elastic contact piece 202 can stably contact or separate from the docking base 101.

[0043] At the same time, the stability and durability of the overall structure of the elastic contact piece 202 can be increased, and the wear caused by long-term use (extrusion) or multiple plugging and unplugging can be reduced.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3

[0046] Reference Figure 3 to Figure 8, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a protective component 300 is provided to connect and isolate the elastic contact piece 202 and the docking base 101; the protective component 300 includes an insulating socket 301 that is clamped with the docking base 101, and the insulating socket 301 is made of insulating material and serves as a handpiece for the staff when the FC optical fiber is docked with the flange connector described in the present application.

[0047] As a further improvement, the insulating socket 301 has a power connection slot 301a and an installation slot 301b, and a power supply 203 and an expansion connector 204 are installed in the power connection slot 301a; wherein the power supply 203 passes electrical energy through the circuit component 200 to ensure that after the circuit is connected, the electrical energy can be transmitted to the indicator light 201 to light up the indicator light 201; the expansion connector 204 can be externally connected to a data collector.

[0048] Furthermore, the positive and negative electrodes of the power supply 203 are both connected to the power connection plate 205, which is clamped in the installation groove 301b. There are two installation grooves 301b, which are arranged on both sides of the power connection slot 301a and extend outward along a track parallel to the edge line of the insulating socket 301.

[0049] Furthermore, the insulating holder 301 is provided with a slot 301c, the bottom of which is provided with a limiting surface 301c-1 capable of abutting against the free end of the hook-shaped mounting portion 202a, the slot 301c is connected to any one of the two mounting slots 301b, and the power connection piece 205 in the other mounting slot 301b extends out of the slot.

[0050] Specifically, the elastic contact piece 202 as a whole has the characteristic of elastic recovery. When in use, the mounting portion 202a with a hook shape is inserted into the slot 301c, and the hook shape is squeezed and contracted. When the mounting portion 202a of the elastic contact piece 202 is inserted into the bottom of the slot 301c, the hook shape recovers and contacts with the limiting surface 301c-1 at the bottom of the slot 301c, which plays a role in limiting and preventing the power connection piece 205 from being separated; and when the mounting portion 202a of the elastic contact piece 202 is inserted into the bottom of the slot 301c, the bent section 202a-1 of the mounting portion 202a contacts with the power connection piece 205 passing through the slot 301c, so that the mounting portion 202a is fixed in the slot 301c by using elastic tension, that is, the elastic contact piece 202 is fixed, and the elastic contact piece 202 is connected to the power connection piece 205, so that the current can be smoothly conducted between the power connection piece 205 and the elastic contact piece 202.

[0051] Furthermore, the docking base 101 is provided with a connection groove 101b for accommodating the portion of the connection piece 205 extending out of the installation groove 301b. After the insulating clamping seat 301 and the docking base 101 are clamped, the portion of the connection piece 205 extending out of the installation groove 301b is inserted into the connection groove 101b.

[0052] Furthermore, the insulating socket 301 is provided with a through threaded hole 301d corresponding to the portion of the electrical connection piece 205 extending out of the mounting groove 301b, and a locking stud 302 is provided in the threaded hole 301d, and the locking stud 302 is made of insulating material; the side wall of the connecting groove 101b corresponding to the connecting groove 101b of the docking base 101 is provided with a long hole 101c intersecting the connecting groove 101b, and the locking stud 302 can pass through the threaded hole 301d and the long hole 101c in sequence and squeeze the electrical connection piece 205 inserted into the connecting groove 101b, so that the electrical connection piece 205 abuts against the side wall of the connecting groove 101b.

[0053] Specifically, when the insulating socket 301 is connected to the docking base 101, the portion of the electrical connection piece 205 extending out of the installation slot 301b is inserted into the connecting slot 101b, and the locking stud 302 is turned to make the electrical connection piece 205 abut against the side wall of the connecting slot 101b, so that current can be smoothly conducted between the electrical connection piece 205 and the docking base 101.

[0054] The remaining structure is the same as that of Example 2.
