[0038] Please refer to Figures 1 to 6The utility model provides a kind of optical fiber connector 100, including connector main body 10 and dust cap, wherein, connector main body 10 is equipped with insertion port 11;Dust cap, including assembly sleeve 20 and elastic cover 30, assembly sleeve 20 is adjustably sleeved in connector main body 10 outside, elastic cover 30 is connected to the one end of assembly sleeve 20 close to insertion port 11, dust cap has the state of closing and opening state;When dust cap is in the state of closing, assembly sleeve 20 is in the first position relative to connector main body 10, and elastic cover 30 closes insertion port 11;When dust cap is in the state of opening, assembly sleeve 20 is in the second position relative to connector main body 10, and elastic cover 30 is pressed against connector main body 10, to make insertion port 11 open.

[0039] The utility model discloses the above scheme, when operator needs to connect optical fiber connector 100 with external device, can directly move dust cap relative to connector main body 10 from the first position to the second position, so that connector main body 10 abuts against elastic twist cover, so that dust cap is switched from closed state to open state, the whole dust cap opening process does not need to disassemble dust cap, avoid the trouble brought by separating parts, and, adopt elastic twist cover in dust cap structure, can play the role of reset, can also be used for closing insertion port 11, save the reset piece such as compression spring or torsional spring.In addition, assembly sleeve 20 is sleeved in connector main body 10 outside, and further protection is formed to connector main body 10.

[0040] The structure of the above-mentioned elastic cover 30 is various, in some embodiments of the utility model, one side edge of the elastic cover 30 is connected to the port of the assembly sleeve 20, and the other side edge of the elastic cover 30 is pressed against the end port of the assembly sleeve 20 under the action of its elastic force.

[0041] Preferably, in some embodiments of the utility model, the elastic cover 30 includes two elastic twist covers, and the two elastic twist covers are respectively connected to the opposite sides of the one end of the assembly sleeve 20 close to the insertion port 11. When the dust cap is in the state of closing, the two elastic twist covers are in contact with the two sides of the assembly sleeve 20. In this way, when the connector main body 10 abuts against the two elastic twist covers, the stress on both sides is balanced, which can avoid the problem of difficult opening caused by unilateral stress.

[0042] The specific structure of the elastic twist cover is various, for example, the two elastic twist covers are both provided as a quarter spherical surface, and the two are combined to form a half spherical surface and cover the plug-in interface 11. In some embodiments of the utility model, each elastic twist cover comprises a connecting portion 31, an abutting portion 32 and a main body portion 33, the connecting portion 31 is connected to the assembly sleeve 20, and the abutting portion 32 is connected between the connecting portion 31 and the main body portion 33; when the dustproof cap is in the closed state, the main body portions 33 of the two elastic twist covers are adhered, and the abutting portions 32 are away from the periphery of the plug-in interface 11; when the dustproof cap is in the open state, the main body portions 33 of the two elastic twist covers are separated, and the abutting portions 32 abut against the periphery of the plug-in interface 11. The cooperation of the two elastic twist covers not only improves the dustproof effect of the fiber connector 100, but also simplifies the operation process and enhances the protection of the connector.

[0043] The elastic twist cover can be connected to the assembly sleeve 20 by clamping, hot melting connection and the like. In some embodiments of the utility model, opposite sides of the peripheral wall of the end of the assembly sleeve 20 close to the plug-in interface 11 are penetrated by clamping interfaces 22, the connecting portions 31 of the two elastic twist covers are clamped in the clamping interfaces 22, and the abutting portions 32 are exposed outside the clamping interfaces 22. Through the cooperation of the clamping interfaces 22 of the assembly sleeve 20 and the connecting portions 31 of the elastic twist cover, the structure stability of the dustproof cap of the fiber connector 100 is higher, and the assembly is more convenient.

[0044] The connecting portion 31 and the assembly sleeve 20 can be clamped by elastic buckles or clamped by the structure of the clamping convex 25 and the clamping hole 34. Specifically, in some embodiments of the utility model, the connecting portion 31 is provided with a clamping hole 34, and the wall surface of the clamping interface 22 is provided with a clamping convex 25, and the clamping convex 25 is clamped in the clamping hole 34. Through the cooperation of the clamping hole 34 and the clamping convex 25, the structure is stable, the operation is convenient, the cost is high, and it is suitable for the design of the dustproof cap of the fiber connector 100.

[0045] In order to further facilitate the assembly of the connecting portion 31 of the elastic twist cover into the assembly clamping interface 22, in some embodiments of the utility model, the side surface of the clamping convex 25 facing the plug-in interface 11 is inclined in the protruding direction away from the plug-in interface 11.

[0046] In some embodiments of the utility model, the inner side of the end surface of the assembly sleeve 20 close to the plug-in interface 11 is provided with an avoiding gap 23, and the avoiding gap 23 penetrates to the clamping interface 22. The avoiding gap 23 not only can position when the connecting portion 31 is assembled, but also can improve the assembly efficiency and the clamping stability, and when the connector main body 10 abuts against the abutting portion 32, the abutting portion 32 can retreat into the avoiding gap 23, and the assembly sleeve 20 and the connector main body 10 do not need to leave a gap for the abutting portion 32 to bend, which is beneficial to improve the compactness of the structure.

[0047] In some embodiments of the utility model, when the dustproof cap is in the closed state, the abutting top 32 extends in the direction away from the joint interface 22 along the plug interface 11. In this way, the abutting top 32 is prevented from being deformed by 90 degrees, which causes the abutting top 32 to break due to the large internal stress, and the force required for the connector body 10 to be ejected is reduced, which facilitates the operator to open the dustproof cover.

[0048] The assembly sleeve 20 and the connector body 10 can be connected in various ways. In some embodiments of the utility model, the inner wall of the assembly sleeve 20 is provided with two clamping grooves, and the outer wall of the connector body 10 is provided with a positioning protrusion. The positioning protrusion is switchably clamped in the two clamping grooves to switch the first position and the second position of the assembly sleeve 20.

[0049] In some other embodiments of the utility model, the inner wall of the end of the assembly sleeve 20 away from the plug interface 11 is provided with an adjusting protrusion 21, the outer wall of the connector body 10 is provided with a first protrusion 12 and a second protrusion 13, and the second protrusion 13 is arranged on the side of the first protrusion 12 away from the plug interface 11. When the dustproof cap is in the closed state, the adjusting protrusion 21 is clamped between the first protrusion 12 and the second protrusion 13. When the dustproof cap is in the open state, the adjusting protrusion 21 is clamped on the side of the second protrusion 13 away from the plug interface 11.

[0050] The adjusting protrusion 21 of the assembly sleeve 20 and the protrusion of the connector body 10 are clamped, which improves the assembly efficiency and clamping stability of the dustproof cap of the optical fiber connector 100.

[0051] In some embodiments of the utility model, the outer wall of the assembly sleeve 20 is provided with anti-skid lines 24. In this way, the operator can pinch the anti-skid lines 24 of the assembly sleeve during the process of ejecting the dustproof cover through the connector body 10, which is more convenient to use.

[0052] The above is only an exemplary embodiment of the utility model, and does not limit the patent range of the utility model. Any equivalent structural transformation made by using the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
