[0007] Optionally, it also includes a circuit board and a reinforcement back plate, the socket interface and the reinforcement back plate are respectively arranged on opposite sides of the circuit board, the reinforcement back plate is provided with at least one positioning boss passing through the circuit board, and the socket interface is provided with at least one second positioning hole whose position corresponds to the positioning boss.

[0008] Optionally, the plug has at least one foot, which is arranged on the connecting surface between the plug and the socket interface. The socket interface is provided with at least one first positioning hole corresponding to the position of the foot.

[0050] In order to fully understand the present invention, the present invention is described in detail through the following specific embodiments and in combination with the accompanying drawings. Those skilled in the art can understand the purpose, characteristics and effects of the present invention from the contents disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the inventive point of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. The following embodiments will further describe the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the claims of the present invention. The description is as follows:

[0051] like Figures 1 to 3 As shown, the pluggable optical module 100 according to the embodiment of the present invention comprises: a socket interface 1 , a frame 2 , two guiding components 3 and a plug 4 .

[0052] The socket interface 1 is arranged on the circuit board 5 and is connected to the circuit board 5 by signal. The socket interface 1 may be provided with a plurality of contacts 13 for signal connection with the plug 4. In detail, the socket interface 1 is a C-shaped opening, and the opening just accommodates the photoelectric conversion module in the plug 4. The plug 4 includes an optical fiber interface and an electrical interface. The electrical interface end has a printed circuit board, and the printed circuit includes the aforementioned photoelectric conversion module and electrical signal contacts. The other end of the photoelectric conversion module is connected to the optical fiber interface. The electrical signal contacts on the plug 4 and the photoelectric conversion module are arranged on the same side, which can shorten the electrical signal connection distance and thus improve the signal transmission quality.

[0053] The frame 2 surrounds the socket interface 1. In this embodiment, the frame 2 is rectangular, but the invention is not limited thereto. Two sides of the frame 2 are respectively provided with engaging grooves 21.

[0054] The two guide members 3 are disposed parallel to each other on both sides of the frame 2 (i.e., on both sides of the engaging groove 21). The two guide members 3 define an opening E for the plug 4 to be inserted from the outside (refer to Figure 2 ). The first ends P of the two guide members 3 are fixed to the frame 2, wherein the first ends P are the ends of the guide members 3 opposite to the opening E. The two guide members 3 each include a guide rail 31, an elastic arm 32 and a locking member 33. Figure 4 and Figure 5 The guide rail member 31 is provided with a guide rail 311 facing the socket interface 1 , the elastic arm 32 has an elastic structure to store elastic force, and the locking member 33 is connected to the elastic arm 32 and is located corresponding to the engaging groove 21 .

[0055] The two parallel sides of the plug 4 have features 41 corresponding to the guide rail 311 (the other side is omitted in the figure), so that the plug 4 can slide relative to the guide rail 31 to connect to the socket interface 1 or move away from the socket interface 1.

[0056] Next, it will be described how to assemble the pluggable optical module 100 of the present invention and how to achieve pluggability (separating the socket interface 1 and the plug 4 ).

[0057] First, according to Figure 1 , the socket interface 1 and the frame 2 are first assembled on the circuit board 5, and the two guide members 3 are fixed to the frame 2 at their first ends P (for example, by screwing), that is, Figure 2 At this time, only one end of the guide member 3 is connected to the frame 2, and the other end (the end close to the opening E) can move freely.

[0058] Next, align the features 41 on both sides of the plug 4 with the two guide rails 311, push the plug 4 in to a fixed point, and then Figure 3 As shown, the locking member 33 is pressed down, and the locking member 33 is deformed under the guidance of the chamfer on the frame 2, and finally falls into the engaging groove 21 and interferes with the engaging groove 21. At this time, the locking member 33 limits the movement of the plug 4, so that the plug 4 can be stably connected to the socket interface 1.

[0059] On the other hand, when the locking member 33 and the engaging groove 21 are no longer interfering with each other, the movement of the plug 4 is no longer restricted by the locking member, and the plug 4 can be withdrawn from the socket interface 1 through the opening E, that is, it returns to the state in which the plug 4 is in the state of being in the socket interface 1. Figure 2 status.

[0060] In this embodiment, if Figure 5 As shown, the plug 4 has at least one foot 42, which is disposed on the connection surface between the plug 4 and the socket interface 1. The socket interface 1 is provided with at least one first positioning hole 11 (such as Figure 1 and Figure 2 As shown). The number of the first positioning holes 11 is not less than the number of the foot posts 42. Because of the presence of the foot posts 42, Figure 2 In the embodiment, the plug 4 is engaged with the guide member 31 in a manner of being slightly inclined but not completely parallel to the plane of the circuit board 5. When the plug 4 is pushed to a fixed point, the position of the leg 42 corresponds to the first positioning hole 11. At this time, the locking member 33 is pressed down, and the leg 42 is inserted into the first positioning hole 11. In addition to interfering with the engaging groove 21, the locking member 33 also forces the plug 4 to be unable to move upward, and the leg 42 must move upward to escape from the first positioning hole 11. In this way, the plug 4 is locked by the locking member 33. When the locking member 33 and the engaging groove 21 no longer interfere with each other, the elastic force accumulated by the elastic arm 32 causes the guide member 3 to bounce upward, so that the plug 4 has enough activity to allow the leg 42 to escape from the first positioning hole 11. At this time, the plug 4 can be withdrawn from the socket interface 1 along the guide rail 311.

[0061] The above-mentioned embodiment is one of the ways in which the locking member 33 restricts the movement of the plug 4, but the present invention is not limited thereto, and the structure of the locking member 33 and the plug 4 can be adjusted so that the plug 4 can be restricted by the locking member 33. In addition, the shape of the locking member 33 and the engaging groove 21 is not limited to the shape of the hook and groove shown in the figure, and the specific shape can be changed and modified as needed.

[0062] In summary, since the pluggable optical module 100 of the present invention is assembled on the side of the circuit board 5 and the plug 4 is plugged in and out, only a very small assembly space is required. Figure 7 As shown, a large number of pluggable optical modules 100 of the present invention can be stacked in a small space, maximizing the space utilization. In addition, since the plug 4 of the pluggable optical module 100 of the present invention directly covers the socket interface 1 and is restricted by the locking member 33, the socket interface 1 can be firmly and tightly fitted to prevent external moisture and dust particles from interfering, thereby improving the water and dust protection capability of the pluggable optical module 100.

[0063] Furthermore, in this embodiment, if Figures 2 to 5 As shown, both ends of the elastic arm 32 are connected to the guide rail member 31. That is, the elastic arm 32 as a whole can be used as an elastic structure to store elastic potential energy. The elastic arm 32 is connected to the guide rail member 31 at the first end P, and the other end (the end close to the opening E) opposite to the first end P is also connected to the guide rail member 31. When the elastic arm 32 releases the elastic potential energy and bounces upward with the first end P as a rotation pivot, it drives the guide rail member 31 and can indirectly drive the plug 4, so that the foot 42 of the plug 4 is separated from the first positioning hole 11.

[0064] Furthermore, in this embodiment, if Figures 3 to 5 As shown, the locking member 33 includes a fulcrum portion 331, a buckle portion 332 and a pull portion 333. The fulcrum portion 331 is against the outer side of the guide rail member 31, and the buckle portion 332 is located at a position corresponding to the engaging groove 21, and is a component that is actually engaged with the engaging groove 21. The pull portion 333 is located at the opening E, and the buckle portion 332 and the pull portion 333 are connected to the two ends of the fulcrum portion 331. The fulcrum portion 331, the buckle portion 332 and the pull portion 333 can be regarded as a lever, with the fulcrum portion 331 serving as a fulcrum, and the buckle portion 332 and the pull portion 333 serving as the two ends of the fulcrum. Figure 6B As shown in FIG. 1 , when the buckle portion 332 of the lock member 33 interferes with the engaging groove 21, the user can pull the pulling portion 333 inward as shown by the arrow, and the buckle portion 332 moves outward, thereby temporarily breaking away from the mutual interference with the engaging groove 21; at this time, the elastic arm 32 releases the accumulated elastic potential energy and bounces upward, driving the buckle portion 332 to release the mutual interference with the engaging groove 21 (as shown in FIG. 1 ). Figure 2 shown).

[0065] Furthermore, in this embodiment, if Figure 1As shown, the pluggable optical module 100 also includes the aforementioned circuit board 5 and the reinforcing back plate 6. The reinforcing back plate 6 has a higher structural strength than the flexible circuit board 5 (usually a printed circuit board). The socket interface 1 and the reinforcing back plate 6 are respectively arranged on the opposite sides of the circuit board 5. The reinforcing back plate 6 is provided with at least one positioning protrusion 61 penetrating the circuit board 5. The socket interface 1 is provided with at least one second positioning hole 12 corresponding to the positioning protrusion 61. The number of the second positioning holes 12 is not less than the number of the positioning protrusions 61. The reinforcing back plate 6 can assist the socket interface 1 in being positioned on the circuit board 5.

[0066] For convenience, in this embodiment, the first positioning hole 11 and the second positioning hole 12 are connected to form a through hole. The first positioning hole 11 is located above the through hole for positioning the pin 42 of the plug 4; the second positioning hole 12 is located below the through hole for positioning the socket interface 1 on the circuit board 5.

[0067] Furthermore, in this embodiment, if Figure 1 As shown, the pluggable optical module 100 further includes a transverse connecting arm 7 connecting the first ends P of the two guiding members 3 to facilitate assembly.

[0068] Furthermore, in this embodiment, if Figure 5 As shown, the plug 4 has an annular groove 43, which is disposed around the connection surface between the plug 4 and the socket interface 1. The annular groove 43 can accommodate a sealing strip to further enhance the water and dust protection capability of the pluggable optical module 100.

[0069] Furthermore, in this embodiment, the surface of the plug 4 is provided with heat dissipation fins 44, which have a large surface area for heat dissipation of the pluggable optical module 100. The heat dissipation fins 44 and the body of the plug 4 can be two parts, and the heat dissipation fins 44 are assembled on the surface of the plug 4; in other examples, the heat dissipation fins 44 can be integrally formed on the surface of the plug 4.

[0070] The present invention has been disclosed above with preferred embodiments, but those skilled in the art should understand that the embodiments are only used to describe the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiments should be considered to be within the scope of the present invention. Therefore, the protection scope of the present invention shall be based on the scope of the content defined in the claims.
