Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0024] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] As shown in the accompanying drawings, a communication connector includes a plug end 9 and a mating end 3, wherein the plug end is plugged into and connected to the mating end 3; the plug end 9 is provided with a plurality of plug pins 7, and the mating end 3 is provided with a plurality of locking components that cooperate with the plug pins 7 and lock the plug pins 7. The locking assembly includes a drive mechanism, a compression sleeve 18, and a locking head. The locking head includes a fixing part 12 and a locking part. The locking part is integrally disposed at one end of the fixing part 12. The locking part includes a plurality of locking fan rings 17 arranged in a ring array at one end of the fixing part 12. The plurality of locking fan rings 17 surround to form a locking cavity that cooperates with the plug-in post 7. The compression sleeve 18 is fitted onto the locking part. The drive mechanism is used to drive the compression sleeve 18 to deform so that the locking part is tightly attached to the plug-in post 7.

[0026] In the above solution, by setting a locking assembly, which includes a drive mechanism, a compression sleeve and a locking head, the plug is locked by the drive mechanism after the plug is inserted into the locking head. During the insertion process of the plug and the locking part, there will be no large friction between the plug and the locking part, which greatly reduces the probability of damage to the plug and the locking part.

[0027] The insertion end 3 is provided with an insertion hole 6, and the locking component is disposed in the insertion hole 6.

[0028] In another embodiment of the present invention, the driving mechanism includes a driving sleeve 13, a push rod 4, and a pushing sleeve 1. The driving sleeve 13 is fitted onto the extrusion sleeve 18. The inner ring wall of the driving sleeve 13 is a conical surface 10, and the outer ring wall of the extrusion sleeve 18 is a conical surface 19. The push rod 4 is disposed on the outer circumferential surface of the driving sleeve 13. The insertion end 3 is provided with a movable groove 5 for the push rod 4 to move. The pushing sleeve 1 is fitted onto the insertion end 3. One end of the push rod 4 passes through the movable groove 5 and engages with the slot 23 on the inner ring wall of the pushing sleeve 1. The end of the pushing sleeve 1 away from the insertion end 3 can be engaged with the insertion end 9.

[0029] In this embodiment, the compression sleeve 18 is made of rubber, and the locking fan ring 17 is made of flexible material. Furthermore, to enhance the driving effect of the push ring on the drive sleeve, two adjacent drive sleeves 13 are connected by a fixing rod 20, and the insertion end 3 is provided with a movable groove 21 for the fixing rod 20 to move.

[0030] In the above scheme, after the plug-in post is inserted into the plug-in hole and enters the flexible connecting tube, the push sleeve is pulled towards the plug-in end. During the movement of the push sleeve to the right, the groove on the push sleeve also moves to the right, thereby driving the drive sleeve to move to the right. During the movement of the drive sleeve, the first conical surface on the drive sleeve and the second conical surface on the extrusion sleeve move relative to each other. The first conical surface extrudes the second conical surface, and the extrusion sleeve deforms, thereby driving the locking fan ring to fit tightly against the outer circumferential surface of the plug-in post. The connection between the locking part and the plug-in post is completed. This solution addresses two key issues. First, by using a pushing sleeve to move a driving sleeve, the extrusion sleeve deforms and applies a force to the locking ring, ensuring it fits tightly against the surface of the insertion post. This connects the locking part to the insertion post, minimizing friction between them during insertion. The insertion of the insertion post into the locking part ensures a reliable connection and reduces the probability of damage to either the insertion post or the locking part. Second, the use of a flexible material for the locking ring effectively reduces gaps between them, further enhancing connection stability.

[0031] As those skilled in the art will know, since the locking fan ring is made of a flexible material, the end of the locking fan ring away from the mounting part is prone to slight deformation. Furthermore, the locking fan ring droops under its own weight. Moreover, after the plug is removed, the end of the locking fan ring is also prone to deformation under the action of the original compression sleeve. This causes the plug to abut against the end of the locking fan ring when it is inserted into the locking part, resulting in the locking fan ring being squeezed and deformed under the action of the plug, eventually leading to damage. Therefore, in this embodiment, the locking assembly further includes a spreading mechanism, which is used to spread the end of the locking part before the plug 7 is inserted into the locking head.

[0032] Specifically, the opening mechanism includes an opening ring 15 and several mating pieces 16. The mating pieces 16 are located at the end of the locking fan ring 17 away from the fixing part 12, forming a trumpet shape. A connecting rod 14 is provided at one end of the driving sleeve 13. The opening ring 15 is located at the end of the connecting rod 14 away from the driving sleeve 13. The outer ring surface of the opening ring 15 is conical, and it contacts the inner wall surface of the mating pieces 16. Before the insertion pin is inserted into the locking part, the opening ring contacts the trumpet-shaped mating pieces, providing support and allowing the insertion pin to be smoothly inserted into the locking part. As the driving sleeve moves to the right, it drives the opening ring to move to the right as well. At this time, the opening ring disengages from the mating pieces, and the opening ring no longer provides support. The locking fan ring can then make tight contact with the insertion pin under the action of the compression sleeve. This prevents the opening ring from affecting the fixation of the insertion pin in the locking part.

[0033] In another embodiment of the present invention, the plug-in end 9 is provided with a snap-fit ​​component that can engage with the push sleeve 1.

[0034] In this embodiment, the snap-fit ​​assembly further includes a spring 11 and a snap-fit ​​plate 8. The insertion end 9 is provided with a mounting hole for installing the snap-fit ​​assembly. One end of the spring 11 is fixedly connected to the bottom of the mounting hole, and the other end is fixedly connected to the snap-fit ​​plate 8. One end of the snap-fit ​​plate 8 extends out of the mounting hole. The inner wall of the push sleeve 1 is provided with a fixing groove 2 that cooperates with the snap-fit ​​plate 8. One end face of the snap-fit ​​plate 8 is an inclined surface.

[0035] In the above scheme, on the one hand, the positioning connection between the insertion part and the mating part is achieved by applying a limit to the push sleeve through the snap-fit ​​component. On the other hand, during the process of the drive sleeve squeezing the compression sleeve, the compression sleeve will give the drive sleeve a reaction force. This reaction force acts on the push sleeve, making the fixing groove on the push sleeve fit more tightly with the snap-fit ​​plate.

[0036] In order to prevent the extrusion sleeve from shifting during the extrusion process, the locking head is provided with limiting rings 22 at both ends to limit the extrusion sleeve 18.

[0037] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
