Through a rotatable connector, better coupling efficiency is achieved when a wire connector fixed to the connector is mated with an external wire connector. Furthermore, by designing multiple take-up structures and winding spaces on the winding fixture, multiple wires of unequal lengths can be wound around the take-up structures, thereby achieving single routing and ensuring the stability of the electro-optical device's characteristics. The following detailed description, in conjunction with the accompanying drawings, illustrates possible embodiments of the invention. However, it should be noted that these details are not intended to limit the scope of the claims made in this invention, but are merely for the convenience of those skilled in the art.

[0019] Please refer to Figures 1 and 2. Figure 1 is a perspective view of a winding fixture according to an embodiment of the present invention, and Figure 2 is another perspective view of a winding fixture according to an embodiment of the present invention. The winding fixture of the present invention includes a winding base 10 and a connector base 11. The winding base 10 has a base body 101, a plurality of first take-up structures 102a, second take-up structures 102b, and a circuit board fixing structure 103, wherein the plurality of first take-up structures 102a and the second take-up structures 102b are formed on a first surface (upper surface) of the base body 101, and the circuit board fixing structure 103 is formed on a second surface (lower surface) of the base body 101, and the second surface of the base body 101 is opposite to the first surface of the base body.

[0020] One end (front end) of the connector 11 is rotatably connected to one end (rear end) of the winding seat 10, and the other end (rear end) of the connector 11 has a plurality of connector receiving structures 111. Further, one end (rear end) of the winding seat 10 extends to opposite sides to form two shafts 105, and one end (front end) of the connector 11 forms two opposing claw-shaped pivots 112, which are pivotally connected to the two shafts 105, so that one end (front end) of the connector 11 is rotatably and detachably connected to one end (rear end) of the winding seat 10. If the plurality of connector receiving structures 111 of the current connector 11 are not suitable for the current type of the plurality of wiring connectors 22, the current connector 11 can be disassembled and replaced with a connector 11 suitable for the current type of the plurality of wiring connectors 22.

[0021] Please refer to Figures 2 and 3 simultaneously. Figure 3 is a schematic diagram of the scenario where the electro-optic module of this embodiment is fixed to the winding fixture. The circuit board fixing structure 103 is used to fix the circuit board 20 of the electro-optic module to the winding seat 10. Further, the circuit board fixing structure 103 includes a locking member 1031, two opposing first baffles 1032, and two adjacent second baffles 1033. The locking member 1031 connects to the second baffles 1033 and protrudes from the second baffles 1033 to lock the circuit board 20. When the circuit board 20 is locked to the winding seat 10, the first side (rear side) of the circuit board 20 abuts against the second baffle 1033, and the two second sides (left and right sides) of the circuit board 20 adjacent to the first side (rear side) abut against the two first baffles 1032.

[0022] Please refer to Figures 1, 4, and 6 simultaneously. Figure 4 is a perspective view of the electro-optic module fixed to the winding fixture according to an embodiment of the present invention, and Figure 6 is a perspective view of the electro-optic device according to an embodiment of the present invention. A plurality of first take-up structures 102a define a winding space 104 on the first surface (upper surface) of the base 101. The winding space 104 cooperates with the plurality of first take-up structures 102a to wind a plurality of wires 21 of the electro-optic module in the winding space 104 for take-up (that is, the plurality of wires 21 are wound around the plurality of first take-up structures 102a in the winding space 104 for take-up). The second take-up structure 102b is used to hook the plurality of wires 21 after they are wound in the winding space 104.

[0023] Additionally, a plurality of connector receiving structures 111 are used to receive and fix a plurality of connectors 22 connected to a plurality of wires 21. Further, each of the plurality of connector receiving structures 111 is recessed to form a receiving space 1111 for receiving the connector 22, and one end of each connector receiving structure 111 has a connector retainer 1112 to secure the connector 22 in the receiving space 1111. It is worth noting that in some cases, the types of the plurality of connectors 22 do not necessarily have to be completely different; for example, some may be LC connectors and some may be RCP connectors.

A second take-up structure 102b is disposed between opposite sides (left and right sides) of the base 101 and defines an optical element storage space 106 on one side (e.g., the right side) of the base 101 for storing optical elements 23 connected to the plurality of wires 21 of the electro-optic module, such as, but not limited to, a wavelength division multiplexer. By arranging the two first take-up structures 102a of equal length and aligned on opposite sides of the base 101, and by using the second take-up structure 102b to hook the plurality of wires 21 wound in the winding space 104, light loss can be reduced and optical coupling efficiency can be increased.

[0025] In addition, the two first take-up structures 102a disposed on opposite sides (left and right sides) of the seat body 101 are two hook-shaped structures extending from opposite sides (left and right sides) of the seat body 101, and the second take-up structure 102b disposed between opposite sides (left and right sides) of the seat body 101 is another hook-shaped structure formed on the first surface (upper surface) of the seat body 101 facing the other side (e.g., the left side) of the seat body 101.

The other end (rear end) of the connector 11 extends further to form two opposing fixing portions 113. The two fixing portions 113 cooperate with the fixing member 31 to fix the winding jig in the accommodating space 301 of the electro-optical device packaging box 30. In this embodiment, the fixing portion 113 is designed in a T-shape, and the fixing member 31 is correspondingly designed in an M-shape. However, the present invention is not limited to this; it mainly depends on the type of the connector 22. As long as the type of connector 22 is met, the shapes of the fixing portion 113 and the fixing member 31 are designed to correspond to achieve the function of fixing the winding jig in the accommodating space 301 of the electro-optical device packaging box 30.

[0027] Referring to Figures 4 and 6, the present invention provides an electro-optic device, which includes an electro-optic module and a winding fixture. The electro-optic module includes a circuit board 20, a plurality of wires 21, connectors 22, and optical elements 23.

After strengthening the tightness of the circuit board 20 and the winding seat 10, the optical element 23 is placed in the optical element storage space 106, and a plurality of wires 21 are wound in the winding space 104. After the plurality of wires 21 are wound around a plurality of first take-up structures 102a, the plurality of wires 21 are hooked through the second take-up structure 102b to take up the wires. Finally, the winding fixture and the fixed electro-optic module are removed from the stage, thus completing the electro-optic device as shown in Figure 6.

The electro-optical device packaging cover 32 is used to cover the electro-optical device packaging box 30 and has screw holes for screws 33 to lock the electro-optical device packaging cover 32 to the electro-optical device packaging box 30. Furthermore, the present invention also provides an electro-optical device packaging structure, which includes a winding fixture, an electro-optical device packaging box 30, a fixing member 31, and an electro-optical device packaging cover 32.

Then, the winding jig is fixed in the receiving space 301 of the electro-optical device packaging box 30 using the fastener 31.

To disassemble the electro-optic device, first remove the screws 33, then remove the electro-optic device enclosure cover 32, and finally remove the fixing member 31. This allows the winding fixture and electro-optic module to be removed. Next, remove the connector 22 from the connector base 11, unhook the winding wire 21 from the second take-up structure 102b, and unwind the winding wire 21 from the first take-up structure 102a. Remove the wire from the winding space 104, and remove the optical element 23 from the optical element storage space 106. This yields the winding fixture and electro-optic module as shown in Figure 4. Finally, remove the electro-optic module from the winding fixture, thus completing the disassembly of the electro-optic device.
