Technical Field

[0001] The utility model relates to an adapter, in particular to an optical fiber adapter. Background Art

[0002] Generally, the optical fiber in the optical fiber adapter can be coupled with the optical path of the docking component. The optical fiber adapter can be used for plugging and unplugging a fiber optic connector. In order to prevent external dust from invading the optical fiber adapter when it is not plugged in or unplugged and affecting the internal optical fiber, the optical fiber adapter is pivotally connected with a movable door as a precaution.

[0071] See also Figure 2 , which is a schematic diagram of the appearance of the optical fiber adapter 100. In some embodiments, the optical fiber adapter 100 can be applied to a data communication network, a cable TV network, or an optical fiber communication network, and is used for optical fiber signal transmission of a 4G / LTE / 5G communication network.

Figure 5 is an exploded schematic diagram of the bottom view of the optical fiber adapter 100, Figure 6 FIG. 1 is a schematic diagram of the appearance of the door piece 2. The optical fiber adapter 100 includes a seat body 1 and a door piece 2. The seat body 1 includes a receiving groove 10, a socket 11 and a door stopper 12. The socket 11 is connected to the receiving groove 10. The door stopper 12 is located at the bottom of the socket 11. The door piece 2 is located in the receiving groove 10 and closes the socket 11 (such as Figure 7 as shown) or open socket 11 (as shown Figure 8 As shown in the figure, the door sheet 2 has pivotal portions 21 on both sides, each pivotal portion 21 is adjacent to the door stop portion 12 and is pivotally connected to the two side walls 13 of the base body 1, and the outer side surface of the door sheet 2 includes a protrusion 22 arranged adjacent to the door stop portion 12.

Figure 8The optical fiber adapter 100 is a side cross-sectional schematic diagram after being plugged into the optical fiber plug 200. The optical fiber adapter 100 is suitable for plugging into the optical fiber plug 200. The optical fiber plug 200 has a connecting body 201 and a pin 202. The pin 202 is exposed at the center of the surface 201b of the connecting body 201. When the optical fiber plug 200 is inserted into the socket 11 of the optical fiber adapter 100, the surface 201b of the connecting body 201 will first contact the protrusion 22, and there is a spacing distance between the pin 202 and the door piece 2; then, the optical fiber plug 200 is continuously pushed into the receiving groove 10 of the optical fiber adapter 100, and the pin 202 and the door piece 2 are in a state of not contacting and not colliding with each other. At this time, the door piece 2 is pushed and rotated around the pivot portion 21 as the center, and the door piece 2 rotates and swings toward the inner side and the bottom direction of the receiving groove 10, so that the protrusion 22 abuts against the bottom surface 201a of the connecting body 201 of the optical fiber plug 200. Because the protrusion 22 abuts against the bottom surface 201a of the connecting body 201, the optical fiber plug 200 will not fall to the bottom of the receiving groove 10 due to gravity, thereby preventing the optical fiber plug 200 from being stuck at the bottom of the receiving groove 10 or the door stopper 12, causing the optical fiber plug 200 to be difficult to pull out.

In some embodiments, when the door sheet 2 closes the socket 11, the door sheet 2 abuts against the inner side of the door stop 12, and the protrusion 22 is relatively located at the top of the door stop 12 and adjacent to the entrance of the socket 11.

In some embodiments, the number of the protrusion 22 can be multiple, and the multiple protrusions 22 are disposed at intervals on the outer side of the door sheet 2 and adjacent to the door stopper 12.

[0080] See also Figure 5 In some embodiments, the cross-section of the protrusion 22 is a trapezoidal structure 22a, and the protrusion 22 includes a first inclined surface 221, a second inclined surface 222 and a contact plane 223, the contact plane 223 is connected to one end of the first inclined surface 221 and one end of the second inclined surface 222, the other end of the first inclined surface 221 is connected to the first section 23, the other end of the second inclined surface 222 is connected to the second section 24, and the length of the first inclined surface 221 is less than the length of the second inclined surface 222.

When the door piece 2 is located at the first position 2P1 and closes the socket 11, the door piece 2 located at the first position 2P1 is inclined relative to the entrance of the socket 11 to close the socket 11. At this time, the contact top portion 224 of the protrusion 22 faces the socket 11 and is closer to the entrance of the socket 11 than the second section 24 of the door piece 2, so that the optical fiber plug 200 inserted into the socket 11 again will first contact the contact top portion 224 of the protrusion 22 without causing the pin 202 to contact and collide with the door piece 2.

[0082] When the optical fiber plug 200 is pulled out of the socket 11 of the optical fiber adapter 100, the inner side surface of the door plate 2 is supported by the rebound force of the supporting portion 36 of the elastic plate 32, so that the door plate 2 is pushed and returns to the original position of closing the socket 11, providing dust and pollution prevention, increasing durability and extending the service life of the optical fiber adapter 100, and keeping the accommodating groove 10 clean to ensure reliable optical fiber signal transmission.

[0083] See also Figure 4 and Figure 8 In some embodiments, the door piece 2 has a second position 2P2 located in the accommodating groove 10; when the optical fiber plug 200 is inserted into the accommodating groove 10 of the optical fiber adapter 100, the door piece 2 is pushed to the bottom of the accommodating groove 10, and the door piece 2 is located at the second position 2P2 to open the socket 11. The door piece 2 located at the second position 2P2 is horizontal and the door piece 2 is relatively perpendicular to the entrance of the socket 11; then, the bottom surface 201a of the connecting body 201 of the optical fiber plug 200 contacts the surface of the door stopper 12, so that the optical fiber plug 200 will not fall toward the bottom of the accommodating groove 10 due to gravity, and the optical fiber plug 200 is prevented from being stuck in the accommodating groove 10 or the door stopper 12 and cannot be smoothly pulled out and separated from the optical fiber adapter 100, ensuring that the optical fiber plug 200 can be easily removed, providing convenience of operation.

[0084] See also Figure 4 and Figure 8 In some embodiments, 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 contacts the abutting plane 223 of the protrusion 22, and the bottom surface 201a of the connecting body 201, the abutting plane 223 of the protrusion 22, and the surface of the door stopper 12 are located in the same plane and are flush with each other, so that the optical fiber plug 200 will not fall toward the bottom of the receiving groove 10 due to gravity, and the optical fiber plug 200 is prevented from being stuck in the receiving groove 10 or the door stopper 12 and cannot be smoothly pulled out and separated from the optical fiber adapter 100. In some embodiments, the top portion 241 of the door sheet 2 and the abutting plane 223 contact the front section and the rear section of the bottom surface 201a of the connecting body 201, respectively.

[0085] See also Fig. 9 , which is a schematic diagram of the appearance of the door sheet 2. In some embodiments, the cross section of the protrusion 22 is a semicircular structure 22b; when the optical fiber plug 200 is inserted into the receiving groove 10 of the optical fiber adapter 100, the protrusion 22 of the semicircular structure 22b is pressed against the connecting body 201 of the optical fiber plug 200 in a point contact manner.

[0087] According to some embodiments, by providing a protrusion on the door sheet, when the optical fiber plug is inserted into the receiving groove of the optical fiber adapter, the door sheet is pushed and rotated to the bottom of the receiving groove and is located at the bottom of the optical fiber plug, and the protrusion abuts against the bottom surface of the connecting body of the optical fiber plug. Because the protrusion abuts against the bottom surface of the connecting body, the optical fiber plug will not fall to the bottom of the receiving groove due to gravity, and the optical fiber plug will not be stuck at the bottom of the receiving groove, causing the optical fiber plug to be pulled out unsmoothly.
