[0058] Further, in the present embodiment, the optical fiber connector head 10 comprises a ferrule assembly 11, a connecting barrel 12, a clamping member 13, and a driving mechanism 14, the connecting barrel 12 is sleeved outside the ferrule assembly 11, and an insertion space A for the adapter 20 is formed between the inner side of the connecting barrel 12 and the outer side of the ferrule assembly 11. Figures 12 to 15 As shown, the side wall of the connecting barrel 12 is provided with a mounting port 121 for the movable installation of the clamping member 13, so that the clamping member 13 can move between a locking position B deviated inward of the mounting port 121 and an unlocking position C deviated outward of the mounting port 121, when moving inward of the mounting port 121, the adapter 20 inserted into the insertion space A can be clamped to realize locking, and when the clamping member 13 is deviated outward of the mounting port 121, the adapter 20 is separated from the adapter 20 to be unlocked.

[0059] The driving mechanism 14 comprises a first driving barrel 141 sleeved outside the connecting barrel 12 and a second driving barrel 142 sleeved outside the first driving barrel 141, when the adapter 20 is inserted into the insertion space A, the first driving barrel 141 is driven to rotate from a first position D to a second position E, so as to drive the clamping member 13 to the locking position B to be clamped with the adapter 20, prevent the adapter 20 from being pulled out, realize the locking with the adapter 20, and the optical fiber connector head 10 can communicate with the optical fiber connector head on the adapter 20.

[0060] When the optical fiber connector head 10 is to be separated from the adapter 20, the second driving barrel 142 is axially moved from a third position F to a fourth position G, so that the first driving barrel 141 is rotated to the first position D, so that the clamping member 13 can move outward to the unlocking position C, and then the adapter 20 is pulled out.

[0061] The connection between the optical fiber connector head 10 and the adapter 20 adopts the plug-in and pull-out mode, in the insertion process, the first driving barrel is driven to rotate to realize the clamping of the optical fiber connector head and the adapter, in the pull-out process, the second driving barrel is axially moved to drive the first driving barrel to reverse and return to realize unlocking, the optical fiber connector head 10 can realize the butt joint and unlocking of the optical fiber connector head 10 and the optical fiber adapter 20 of the optical fiber connector 100 in a straight insertion and straight pull-out mode, the connection and unlocking mode is fast, the efficiency is improved, and the clamping position is accurate.

[0062] Further, in the present embodiment, the optical fiber connector head 10 comprises a ferrule assembly 11, a connecting barrel 12, a clamping member 13, and a driving mechanism 14, the connecting barrel 12 is sleeved outside the ferrule assembly 11, and an insertion space A for the adapter 20 is formed between the inner side of the connecting barrel 12 and the outer side of the ferrule assembly 11. Figure 6 、 7As shown, the end of the first driving cylinder 141 is circumferentially distributed with guide heads 1411, which include two or more circumferentially uniformly spaced guide heads for the adapter 20 to axially abut against, thereby driving the first driving cylinder 141 to rotate to the second position E.

[0063] Preferably, the guide heads 1411 extend beyond the end of the second driving cylinder 142, so that the guide heads 1411 can abut against the adapter 20 and be forced to drive the first driving cylinder 141 to rotate to the second position E.

[0064] Further, in the embodiment, the guide heads 1411 include circumferentially arranged guide surfaces 1412, which are inclined toward the other end of the first driving cylinder 141, so that when the adapter 20 abuts against the guide heads 1411, the adapter 20 can not only continue to guide the insertion, but also provide a circumferential rotation driving force to the first driving cylinder 141, thereby driving the first driving cylinder 141 to rotate to the second position E.

[0065] Further, as shown, Figure 8 In some embodiments, the adapter 20 includes a cylinder 21 for being inserted into the insertion space A, and a driving portion 22 for abutting against the end of the first driving cylinder 141, so that during the insertion of the cylinder 21, the driving portion 22 drives the first driving cylinder 141 to rotate from the first position D to the second position E.

[0066] The outer wall surface of the cylinder 21 is provided with a groove 211 for the clamping member 13 to be clamped into, so that after the first driving cylinder 141 rotates to the second position E, the clamping member 13 can be pressed against the groove 211 to avoid the clamping member 13 from being disengaged from the groove 211.

[0067] In the embodiment, the driving portion 22 is arranged on the outer wall surface of the cylinder 21, and the side of the driving portion 22 opposite to the fiber optic connector 10 is provided with a slot 221 for the guide heads 1411 of the end of the first driving cylinder 141 to be inserted into, and the slot 221 is provided with a guide portion 222 for resisting the guide heads 1411, so as to allow the first driving cylinder 141 to rotate.

[0068] Preferably, the guide portion 222 is matched with the guide surfaces 1412, and after the guide surfaces 1412 abut against the guide portion 222, the guide surfaces 1412 and the guide portion 222 are in close contact, and during the insertion and extraction of the fiber optic connector 10, the guide surfaces 1412 slide along the guide portion 222.

[0069] In the embodiment, the outer wall surface of the cylinder 21 is further provided with a guide platform 212, and as shown, Figure 9 The inner wall surface of the connecting cylinder 12 is provided with a guide opening 122 corresponding to the guide platform 212, and during the insertion of the fiber optic connector 10 and the adapter 20, the guide platform 212 is inserted into the guide opening 122, thereby playing a role of guiding and circumferential positioning.

[0070] In some embodiments, the inner opening of the mounting port 121 is smaller than the outer shape of the engaging member 13, which defines the position of the engaging member 13 moving inwardly and also defines the position of the engaging member 13 being engaged with the adapter 20; the outer opening of the mounting port 121 is larger than the outer shape of the engaging member 13, which allows the engaging member 13 to move outwardly and disengage from the adapter 20 when unlocked.

[0071] In the present embodiment, the engaging member 13 is spherical, which is flexible and convenient for rolling adjustment of direction and angle, and also allows the end of the engaging member 13 to protrude from the inner end of the mounting port 121 and be engaged with the adapter 20. In other embodiments, the engaging member 13 can be cylindrical and inserted into the mounting port 121, with both ends being rounded, which allows the engaging member 13 to move along the axis of the mounting port 121 and adjust the relative position with the adapter 20 and the first driving cylinder 141.

[0072] In some embodiments, as shown in Figure 7 , 10 , Figures 12 to 15 the inner wall surface of the first driving cylinder 141 is circumferentially arranged with the first avoiding groove 1413 and the first protrusion 1414. When the first driving cylinder 141 is located at the first position D, the first avoiding groove 1413 is opposite to the engaging member 13, which allows the engaging member 13 to move along the axis of the mounting port 121 and move into the first avoiding groove 1413, thereby providing the unlocking space for the outward movement of the engaging member 13.

[0073] When the first driving cylinder 141 is rotated to the second position E, the first protrusion 1414 abuts against the engaging member 13 and presses the engaging member 13 into the mounting port 121 from the outside, so as to keep the engaging member 13 at the locking position B and allow the end of the engaging member 13 to protrude from the inner end of the mounting port 121 and be engaged into the adapter 20.

[0074] In order to stabilize the rotating direction of the first driving cylinder 141, on the one hand, the outer wall surface of the first driving cylinder 141 is provided with a guide groove L, and further, the guide groove L includes a first guide section L1 arranged circumferentially; on the other hand, the inner side of the second driving cylinder 142 is provided with a second protrusion 1421 engaged with the guide groove L. When the fiber connector 10 is not inserted into the adapter 20, the second protrusion 1421 is located at one end of the first guide section L1.

[0075] When the first driving cylinder 141 is rotated from the first position D to the second position E, the second protrusion 1421 slides from one end of the first guide section L1 to the other end of the first guide section L1.

[0076] When the first driving cylinder 141 is at the second position E, the engaging member 13 is at the locking position B and engaged with the adapter 20, and when the fiber connector 10 is to be pulled out, an external force is required to restore the engaging member 13 to the unlocking position C.

[0077] Preferably, in some embodiments, the guide groove L comprises a second guide segment L2 which is in communication with the first guide segment L1 and is at an angle, the second guide segment L2 is obliquely arranged on the outer wall surface of the first driving cylinder 141, and in the process of moving the second driving cylinder 142 from the third position F to the fourth position G in the external force, the second protrusion 1421 slides along the second guide segment L2, drives the first driving cylinder 141 to rotate to the fifth position H, so that the first protrusion 1414 is separated from the clamping piece 13, so that the adapter 20 can be pulled out.

[0078] In the present embodiment, the second guide segment L2 is at an obtuse angle with the first guide segment L1, so that the first position D, the second position E and the fifth position H are positions in which the first driving cylinder 141 rotates in the same direction in the circumferential direction.

[0079] Further, the inner wall surface of the first driving cylinder 141 is further provided with a second avoiding groove 1415, and the first avoiding groove 1413, the first protrusion 1414 and the second avoiding groove 1415 are arranged in sequence in the circumferential direction, when the first driving cylinder 141 is at the fifth position H, the clamping piece 13 slides along the inner wall surface of the first driving cylinder 141 from the first protrusion 1414 to the second avoiding groove 1415, when the fiber connector 10 is pulled out, the clamping piece 13 can move outwardly to the second avoiding groove 1415 at the mounting port 121, reach the unlocking position C, so that the fiber connector 10 and the adapter 20 are smoothly separated.

[0080] Correspondingly, according to the number of clamping pieces 13 distributed in the circumferential direction on the connecting cylinder 12, a corresponding number of first avoiding grooves 1413, first protrusions 1414 and second avoiding grooves 1415 can be provided on the inner wall surface of the first driving cylinder 141.

[0081] In other embodiments, the second guide segment L2 can also be at an acute angle with the first guide segment L1, so that the first driving cylinder 141 rotates to the second position E from the first position D, and then reversely rotates to the fifth position H. It can be understood that when reversely rotating to the fifth position H, the fifth position H can overlap with the first position D.

[0082] Further, preferably, in the present embodiment, the end of the second guide segment L2 away from the first guide segment L1 is obliquely arranged away from the plug-in direction of the adapter 20, so that when the second driving cylinder 142 moves to the fourth position G in the axial direction away from the adapter 20, it drives the first driving cylinder 141 to rotate to the fifth position H.

[0083] Of course, the end of the second guide segment L2 away from the first guide segment L1 can also be obliquely arranged away from the plug-in direction of the adapter 20, so that when the second driving cylinder 142 moves in the circumferential direction to approach the adapter 20, it drives the first driving cylinder 141 to rotate.

[0084] In some embodiments, combined with Figure 2 , 11 As shown in Figure 16, in order to allow the first drive cylinder 141 to rotate in the same direction to the fifth position H and then reset to the first position D, the drive mechanism 14 further includes a first reset member 143 for providing the first drive cylinder 141 with a reset rotation to the first position D.

[0085] After the second drive cylinder 142 reaches the fourth position G, the adapter 20 is pulled out normally. The locking member 13 is not subjected to pressure. Under the force of the first reset member 143, the first drive cylinder 141 can be pushed to rotate in the opposite direction to the first position D. The locking member 13 also passes through the first protrusion 1414 to the first relief groove 1413, completing the reset of the fiber optic connector 100.

[0086] Preferably, the first reset member 143 is located on the outer wall surface of the connecting cylinder 12 and is arranged circumferentially to provide a circumferential reset driving force to the first driving cylinder 141. The first reset member 143 can be a spring or a spring sheet, and uses the elastic force to drive the first driving cylinder 141 to reset to the first position D.

[0087] Furthermore, in this embodiment, a support portion 123 is provided on the outer ring of the connecting cylinder 12. The support portion 123 is disposed on the collar 125 sleeved onto the connecting cylinder 12. In other embodiments, the support portion 123 may be integral with the connecting cylinder 12. The first driving cylinder 141 is provided with a stop portion 1416 that is circumferentially offset from the support portion 123. The two ends of the first reset member 143 abut against the support portion 123 and the stop portion 1416 respectively, and can provide a circumferential rotational reset force to the first driving cylinder 141.

[0088] Preferably, the side of the support portion 123 opposite to the first reset member 143 limits the reset position of the blocking portion 1416, so that the support portion 123 can play the role of support and limitation, saving space.

[0089] In some embodiments, combined with Figures 4 to 6 As shown in Figure 11, the drive mechanism 14 also includes a second reset member 144 that provides an axial reset force F to the second drive cylinder 142 to the third position, so that the second protrusion 1421 returns from the second guide section L2 to the first guide section L1.

[0090] When the second drive cylinder 142 needs to be reset to the third position F, the second drive cylinder 142 can be released. The second reset member 144 provides an axial force to move the second drive cylinder 142 to the third position F. During the movement of the second drive cylinder 142 to the third position F, the second protrusion 1421 applies force to the first drive cylinder 141 and returns to the first guide section L1. At the same time, under the action of the first reset member 143, the first drive cylinder 141 is driven to return to the first position D.

[0091] The second reset member 144 is a spring or other elastic member sleeved outside the first driving cylinder 141, and abuts against the second driving cylinder 142. When the second driving cylinder 142 is reset to the third position F, the first driving cylinder 141 is driven to rotate to the second position E.

[0092] In combination Figure 5 , 10 , as shown in FIG. 11, in order to stabilize the axial movement direction of the second driving cylinder 142, in the embodiment, the connecting cylinder 12 is provided with a guide groove 124, and the inner wall surface of the second driving cylinder 142 is provided with a guide platform 1422 engaged with the guide groove 124. Of course, the positions of the guide groove 124 and the guide platform 1422 can be interchanged.

[0093] Further, in combination Figure 4 , 5 , in the embodiment, the connecting cylinder 12 is sleeved with a stop ring 15, which can provide support for the second reset member 144, and the second driving cylinder 142 can be sleeved outside the stop ring 15.

[0094] At the tail end of the ferrule assembly 11, a locking sleeve 16 is screwed, which can be screwed with the connecting cylinder 12 and clamps the positioning platform 111 on the outer wall surface of the ferrule assembly 11, so as to connect the ferrule assembly 11, the connecting cylinder 12 and the driving mechanism 14 into one body.

[0095] It can be understood that the above technical features can be used in any combination without limitation.

[0096] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the specification and drawings of the present application, is also included in the patent protection scope of the present application.
