DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The following description will be given with reference to Fig. 2. Here, Fig. 2 is a perspective view showing the appearance of an optical fiber adapter 100 having four insertion ports 11 according to an embodiment of the present invention. In this embodiment, the optical fiber adapter 100 can be applied to a data communication network, a cable television network, or an optical fiber communication network, and can be used for optical fiber signal transmission in a 4G / LTE / 5G communication network.

[0019] The following description will be given with reference to Figures 3 to 6. Figure 3 is a front view of an optical fiber adapter 100 according to an embodiment of the present invention. Figure 4 is an exploded perspective view of the optical fiber adapter 100 according to an embodiment of the present invention, seen from above. Figure 5 is an exploded perspective view of the optical fiber adapter 100 according to an embodiment of the present invention, seen from the bottom side. Figure 6 is a perspective view showing the appearance of a door piece 2 according to an embodiment of the present invention, in which a protruding block 22 on the door piece 2 has an elongated structure.

[0020] The optical fiber adapter 100 includes a base 1 and a door piece 2. The base 1 includes a receiving groove 10, an insertion port 11, and a door stop 12. The insertion port 11 is connected to the receiving groove 10, and the door stop 12 is located at the bottom of the insertion port 11.

[0021] The door piece 2 is positioned within the receiving groove 10 and can rotate to close the insertion opening 11 (as shown in FIG. 7) or open the insertion opening 11 (as shown in FIG. 8). Pivot parts 21 are provided on both left and right sides of the door piece 2 (see FIG. 6), and each pivot part 21 is adjacent to a door stop 12 and rotatably connected to two side walls 13 of the base 1. The door piece 2 includes a protruding block 22 provided adjacent to the door stop 12 on its outer side.

[0022] The following description will be given with reference to Figures 7 and 8. Figure 7 is a side cross-sectional view of an optical fiber adapter 100 according to an embodiment of the present invention when an optical fiber plug 200 is about to be inserted into the optical fiber adapter 100 according to an embodiment of the present invention. Also, Figure 8 is a side cross-sectional view of an optical fiber adapter according to an embodiment of the present invention after an optical fiber plug has been inserted into the optical fiber adapter.

[0023] The fiber optic adapter 100 is suitable for inserting a fiber optic plug 200. The fiber optic plug 200 has a connecting body 201 and a pin 202, and the pin 202 is exposed at the center of the surface 201b of the connecting body 201.

[0024] When the optical fiber plug 200 is inserted into the socket 11 of the optical fiber adapter 100 , the surface 201 b of the connecting body 201 first contacts the protruding block 22 , creating a distance between the pin 202 and the door piece 2 .

[0025] Next, when the optical fiber plug 200 is continuously pushed into the receiving groove 10 of the optical fiber adapter 100, the pin 202 and the door piece 2 reach a state where they are not in contact with each other and are not colliding with each other.

[0026] At this time, the door piece 2 is pushed around the pivot portion 21 to rotate, and the door piece 2 swings so as to rotate toward the inner bottom of the accommodating groove 10, and the convex block 22 abuts against the bottom surface 201a of the connecting body 201 of the optical fiber plug 200.

[0027] Since the convex block 22 abuts against the bottom surface 201a of the connecting body 201, the optical fiber plug 200 is prevented from falling to the bottom of the accommodating groove 10 due to gravity, and the optical fiber plug 200 is prevented from getting caught on the bottom of the accommodating groove 10 or the door stop 12, which prevents the optical fiber plug 200 from being smoothly pulled out.

[0028] 4 and 5 again, the description will be given. In this embodiment, the base 1 is a hollow shell having a long rectangular shape, with an insertion opening 11 formed at one end of the base 1 and a docking port (not numbered) at the other end of the base 1. A through groove 15 that connects the insertion opening 11 and the accommodation groove 10 is formed at the bottom of the base 1. The base 1 has an assembly portion 17 on a side wall 13 adjacent to the through groove 15.

[0029] In this embodiment, the number of insertion slots 11 may be multiple, such as two insertion slots 11 shown in FIG. 10 or four insertion slots 11 shown in FIG.

[0030] 3 and 4, in this embodiment, the base 1 includes side walls 13 located on both sides of the insertion opening 11. Each side wall 13 has a thin wall 131 and a thick wall 132, and each thin wall 131 is disposed to face a position adjacent to the door stop 12, and an axis 131a is defined between each thin wall 131.

[0031] When the door piece 2 closes the insertion opening 11 , the protruding block 22 is positioned relative to the position of the axis 131 a , and each thick wall 132 is provided at a position spaced apart from the door stop 12 .

[0032] In this embodiment, when the door piece 2 closes the insertion opening 11, the door piece 2 contacts the inner surface of the door stop 12, and the convex block 22 is positioned relatively at the upper part (top part, apex) of the door stop 12, adjacent to the entrance of the insertion opening 11.

[0033] 4 and 7, in this embodiment, the optical fiber adapter 100 further includes a support base 3.

[0034] The support base 3 has an elastic sheet 32 ​​, which is positioned in the receiving groove 10 and abuts against the inner surface of the door piece 2 , and the inner surface of the door piece 2 includes a recess 26 .

[0035] The elastic sheet 32 ​​has a top support portion 36 that holds the recessed portion 26 , and the support base 3 has a buckle portion 37 that is combined with the assembly portion 17 .

[0036] Referring to Figure 5, in this embodiment, the door piece 2 is an approximately rectangular plate, and both sides of one end (the horizontal end) of the door piece 2 have pivot portions 21, and the other end (in the height direction perpendicular to the horizontal direction) of the door piece 2 has a top end portion 241.

[0037] The door piece 2 comprises, in order from the pivot part 21 toward the direction away from the pivot part 21, a first part 23 and a second part 24, the first part 23 being upright and the second part 24 being inclined. The protruding block 22 is located in the first part 23, and the top end 241 is located at the end of the (upper) side surface of the door piece 24.

[0038] 5, in this embodiment, the number of the protruding block 22 may be one, and the protruding block 22 is an elongated structure arranged to extend laterally on the outer surface of the door piece 2, but is not limited to this. In this embodiment, the number of the protruding blocks 22 may be multiple, and the multiple protruding blocks 22 are arranged spaced apart from each other on the outer surface of the door piece 2 so as to be adjacent to the door stop 12.

[0039] Referring to FIG. 5, in this embodiment, the cross section of the convex block 22 is a trapezoidal structure 22 a , and the convex block 22 includes a first inclined surface 221 , a second inclined surface 222 , and an abutment plane 223 .

[0040] The abutment plane 223 is connected to one end of the first inclined surface 221 and one end of the second inclined surface, the other end of the first inclined surface 221 is connected to the first portion 23, and the other end of the second inclined surface 222 is connected to the second portion 24. Here, the length of the first inclined surface 221 is shorter than the length of the second inclined surface 222. That is, the above-mentioned door piece 2 being substantially rectangular means that the upper end side of the first portion 23 extending in the vertical direction extends obliquely upward while inclining in a direction away from the abutment plane 223, and then changes direction and extends again in a substantially vertical direction to the top end 241. Therefore, as described above, the length of the first inclined surface 221 is shorter than the length of the second inclined surface 222.

[0041] 4 and 7, in this embodiment, the door piece 2 can also be moved to a first position 2P1 located within the accommodating groove 10, and the convex block 22 includes a vertex portion 224, which is located at the corner between the first inclined surface 221 and the abutment plane 223.

[0042] When the door piece 2 is located at a first position 2P1 where the door piece 2 closes the insertion opening 11, the door piece 2 at the first position 2P1 is inclined with respect to the entrance of the insertion opening 11 to close the insertion opening 11.

[0043] At this time, the apex 224 of the convex block 22 faces the insertion port 11 and is located closer to the entrance of the insertion port 11 than the second part 24 of the door piece 2. When the optical fiber plug 200 is reinserted into the insertion port 11, the pin 202 abuts against the apex 224 of the convex block 22 without contacting or colliding with the door piece 2.

[0044] When the optical fiber plug 200 is pulled out of the insertion port 11 of the optical fiber adapter 100, the inner surface of the door piece 2 is supported by the repulsive force of the top support portion 36 of the elastic sheet 32, and the door piece 2 is pushed back to its original position closing the insertion port 11, thereby providing dust-proof and dirt-proof functions.

[0045] In this way, the receiving groove 10 can be kept clean to increase the durability and service life of the optical fiber adapter 100, thereby ensuring reliable optical fiber signal transmission.

[0046] 4 and 8, in this embodiment, the door piece 2 can also be moved to a second position 2P2 located within the receiving groove 10.

[0047] When the optical fiber plug 200 is inserted into the receiving groove 10 of the optical fiber adapter 100, the door piece 2 is pushed to the bottom of the receiving groove 10, and the door piece 2 moves to the second position 2P2 to open the insertion port 11. That is, at the second position 2P2, the door piece 2 is approximately horizontal, and the door piece 2 is relatively vertical (approximately perpendicular) to the entrance of the insertion port 11.

[0048] Next, the bottom surface 201a of the connecting body 201 of the optical fiber plug 200 contacts the surface of the door stop 12, preventing the optical fiber plug 200 from falling (unnecessarily deep) toward the bottom of the accommodating groove 10 due to gravity, and preventing the optical fiber plug 200 from engaging (getting caught) in the accommodating groove 10 or the door stop 12 and being unable to be pulled out smoothly and removed from the optical fiber adapter 100. As a result, the optical fiber plug 200 can be easily pulled out, and the operation is simple.

[0049] 4 and 8, in this embodiment, when the optical fiber plug 200 is inserted into the receiving groove 10 of the optical fiber adapter 100, the bottom surface 201a of the connecting body 201 abuts against the abutment plane 223 of the protruding block 22.

[0050] The bottom surface 201a of the connecting body 201, the contact surface 223 of the protruding block 22, and the surface of the door stop 12 are all located on the same plane, that is, flush with each other.

[0051] In this way, the optical fiber plug 200 is prevented from falling toward the bottom of the accommodating groove 10 due to gravity (in other words, the optical fiber plug is prevented from falling to a position so deep that it cannot be removed later), thereby preventing the optical fiber plug 200 from getting caught on the accommodating groove 10 or the door stop 12, making it difficult to remove from the optical fiber adapter 100.

[0052] In this embodiment, the top end 241 and the abutment plane 223 of the door piece 2 are in contact with the front and rear portions of the bottom surface 201a of the connecting body 201, respectively.

[0053] Description will be made with reference to Fig. 9. Here, Fig. 9 is a perspective view of the door piece 2. In this embodiment, the cross section of the protruding block 22 is a semicircular structure 22b.

[0054] When the optical fiber plug 200 is inserted into the receiving groove 10 of the optical fiber adapter 100, the convex block 22 of the semicircular structure 22b abuts on the connecting body 201 of the optical fiber plug 200 in point contact.

[0055] 9, in this embodiment, the number of the protruding blocks 22 may be more than one, and the protruding blocks 22 of the semicircular structure 22b are provided on the outer surface of the door piece 2 with a space between them and adjacent to the door stop 12.

[0056] When the optical fiber plug 200 is inserted into the receiving groove 10 of the optical fiber adapter 100, the convex blocks 22 of the multiple semicircular structures 22b abut the connecting body 201 of the optical fiber plug 200 at multiple points by point contact, thereby obtaining a stable contact effect.

[0057] In this way, a protruding block is provided on the door piece, and when the optical fiber plug is inserted into the receiving groove of the optical fiber adapter, the door piece is rotated and pushed to the bottom of the receiving groove, and is positioned at the bottom of the optical fiber plug.

[0058] Furthermore, since the convex block abuts against the underside of the connecting body of the optical fiber plug, it is possible to prevent the optical fiber plug from falling to the bottom of the accommodating groove due to gravity and to prevent the optical fiber plug from getting caught on the bottom of the accommodating groove and becoming unable to be removed smoothly.

[0059] In addition, according to another embodiment of the present invention, when the optical fiber plug is inserted into the insertion port of the optical fiber adapter, the surface of the connecting body first contacts the convex block, and since there is a distance between the pin and the door piece, the pin does not collide with or contact the door piece when the optical fiber plug is inserted.
