Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to an assembled plug structure and connector. Background Technology

[0002] Connectors are key components for achieving circuit connections. Currently, electrical connectors can be categorized based on the type of medium they transmit, including electrical connectors, fiber optic connectors, gas connectors, and liquid connectors. Taking electrical connectors as an example, they typically consist of an insulating core and a metal housing. The core assembly contains conductive terminals responsible for power transmission and signal conduction; the metal housing provides mechanical support and electromagnetic shielding for the core assembly. In conventional connector assembly processes, the core assembly, after wire splicing, needs to be pressed into the housing using an interference fit. This process relies on automated equipment for crimping. Because manual operation cannot achieve the axial pressure and positioning accuracy required for interference fitting, the core assembly cannot be reinstalled after the product leaves the factory. This not only limits the flexibility of on-site connection assembly but also hinders end-users from adjusting wiring configurations according to actual needs. Utility Model Content

[0003] Therefore, it is necessary to provide an assembly-type plug structure and connector to address the problem that the current connector installation method makes it difficult to install after leaving the factory.

[0004] This application provides an assembled plug structure, which includes a housing assembly, a ferrule assembly, a cable sheath, and a locking sleeve.

The cable sheath is disposed within the housing assembly. The locking sleeve is located within the housing assembly and fits over the ferrule assembly and the cable sheath. The locking sleeve includes at least two semi-open latches, which are detachably fastened together. When the latches are fastened, the locking sleeve secures the ferrule assembly and the cable sheath. The locking sleeve also includes an outwardly folded latch, which is an elastic body. The end of the locking sleeve opposite to the free end of the latch is a positioning end. When the positioning end abuts against the positioning platform, the latch flips into the locking groove and abuts against the side wall of the locking groove facing the positioning platform.

[0005] In one embodiment, the ferrule assembly includes a first adapter, the cable sheath includes a second adapter, and the locking sleeve has a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion being axially spaced apart. When the latch is engaged, the first connecting portion is fixedly connected to the first adapter, and the second connecting portion is connected to the second adapter. One of the first adapter and the first connecting portion is configured as an annular groove, and the other is configured as a retaining ring. One of the second adapter and the second connecting portion is configured as an annular groove, and the other is configured as a retaining ring.

[0006] In one embodiment, the lock sleeve includes a first latch and a second latch, which are detachably engaged to form the lock sleeve. At least one of the first latch and the second latch has the locking tongue. The first latch includes a plurality of first ring portions, and the second latch includes a plurality of second ring portions. Each first ring portion and each second ring portion is configured as either a groove or a protruding ring. After the first latch and the second latch are engaged, the plurality of first ring portions and the plurality of second ring portions are correspondingly enclosed to form the first connecting portion and the second connecting portion.

[0007] In one embodiment, the first snap flap has a first mating surface, and the second snap flap has a second mating surface. One of the first mating surface and the second mating surface is provided with a guide pin, and the other is provided with a guide hole. When the first snap flap and the second snap flap are engaged, the first mating surface and the second mating surface are in contact, and the guide pin is inserted into the guide hole.

[0008] In one embodiment, the first connecting portion is configured as a retaining ring, the first connecting portion is disposed on the inner circumferential surface of the lock sleeve and extends to the intersection of the inner circumferential surface of the lock sleeve and the end face of the positioning end, and the end face of the lock sleeve abuts against the positioning platform.

[0009] In one embodiment, the housing assembly includes a first housing and a second housing, the first housing and the second housing being axially detachably connected, the positioning platform and the locking groove being disposed in the first housing, the ferrule assembly passing through the first housing, and the cable sheath passing through the second housing; the cable sheath includes a sleeve body and a snap-fit ​​ring, the snap-fit ​​ring protruding from the outer periphery of the sleeve body, and the assembled plug structure further includes a tail cable sheath, the tail cable sheath being located on the side of the cable sheath away from the ferrule assembly, the tail cable sheath being sleeved on the cable sheath and snapped into place by the snap-fit ​​ring.

[0010] In one embodiment, the cable protector further includes a positioning disc, which protrudes from the sleeve body, and the tail end of the locking sleeve abuts against the opposite sides of the positioning disc, respectively, of the second housing.

[0011] In one embodiment, the assembled plug structure further includes a bushing, and a limiting ring protrudes from the inner circumferential surface of the second housing. The two ends of the bushing respectively abut against the limiting ring and the side of the positioning disk away from the locking sleeve. The bushing is fitted onto the tail wire sleeve. The bushing includes a sleeve and a pressure ring. The pressure ring protrudes from the inner wall surface of the sleeve at the end away from the positioning disk. The snap ring includes a wedge-shaped portion. The wedge-shaped portion is located on the side of the snap ring away from the positioning disk, and the size of the wedge-shaped portion protruding from the sleeve gradually decreases in the direction away from the positioning disk. The pressure ring and the wedge-shaped portion are aligned to jointly clamp the wire sleeve.

[0012] In one embodiment, the assembled plug structure further includes a flexible sleeve, which is fitted over the tail wire sleeve, and a portion of the flexible sleeve passes through the second housing and engages with the second housing.

[0013] In one embodiment, the sheath is configured to be made of metal and is used to connect to and be electrically conductive with a grounding element.

[0014] This application also provides a connector that includes the assembled plug structure described above.

[0015] In the aforementioned assembled plug structure, the locking sleeve is formed by detachable snap-fit ​​flaps. When the snap-fit ​​flaps are engaged, the locking sleeve secures the ferrule assembly and the cable sheath. Thus, by engaging multiple snap-fit ​​flaps, the locking sleeve, ferrule assembly, and cable sheath can be assembled into a stable assembly. Furthermore, when the positioning end abuts against the positioning platform, the locking tongue flips into the locking groove and abuts against the groove wall facing the positioning platform. In other words, the locking sleeve, relying on its locking tongue and positioning end, can also be fixedly connected to the housing assembly, thereby securing the assembly to the housing assembly. In this application, the engagement of the snap-fit ​​flaps, the insertion of the positioning end into the housing assembly and abutting against the positioning platform, and the flipping of the elastic locking tongue into the locking groove and abutting against the groove wall can all be easily performed manually. Therefore, the assembled plug structure provided in this application does not rely on automated equipment during assembly and can be performed manually. Therefore, the modular plug structure allows end users to adjust the wiring configuration according to their actual needs and then assemble it themselves. At the same time, the modular plug structure can also be used for on-site self-assembly, which is highly operable and convenient. Attached Figure Description

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] One embodiment of this application provides a connector including an assembled plug structure. The components of the assembled plug structure are configured for manual assembly. Therefore, end users can perform wire splicing on the assembled plug structure according to their needs and then assemble it themselves, improving the flexibility of machine use. It is readily understood that a connector typically includes a plug structure as a socket and a plug structure as a plug, with the plug and socket mating to achieve connection and conductivity. The assembled plug structure provided in the embodiments of this application can be configured as either a plug or a socket, or both the plug and socket of the connector can be configured as the assembled plug structure described in the embodiments.

[0033] Furthermore, the connector can be configured as an electrical connector, fiber optic connector, gas connector, liquid connector, or mixed connector, etc. This application does not specifically limit it, but for ease of understanding and explanation, the following will use the connector as an electrical connector as an example for explanation.

[0034] See Figures 1 to 5 , Figure 1 This paper shows an isometric schematic diagram of an assembled plug structure according to an embodiment of the present application. Figure 2 for Figure 1 The diagram shows an isometric view of the ferrule assembly, cable sheath, and locking sleeve in the assembled plug structure. Figure 3 for Figure 2 The exploded view of the ferrule assembly, wire sheath, and locking sleeve is shown. Figure 4 for Figure 1The above is a front view of the assembled plug structure. Figure 5 for Figure 4 The diagram shows a cross-sectional view of the assembled plug structure along line AA. An embodiment of this application provides an assembled plug structure 10 including a housing assembly 100, a ferrule assembly 200, a cable sheath 300, and a locking sleeve 400. The ferrule assembly 200, cable sheath 300, and locking sleeve 400 are all disposed within the housing assembly 100. The ferrule assembly 200 is used to transmit electrical energy and electrical signals, and is used to connect cables. The cables can pass through the cable sheath 300 and extend through the cable sheath 300 to the outside of the housing assembly 100.

[0035] The housing assembly 100 includes a positioning platform 111, which is disposed on the inner wall surface of the housing assembly 100. The housing assembly 100 also has a locking groove 112, which is formed on the inner wall surface of the housing assembly 100. A locking sleeve 400 is located inside the housing assembly 100 and fits over the ferrule assembly 200 and the cable sheath 300. Figure 3 The locking sleeve 400 includes at least two semi-open latches 401, which are detachably snapped together. When the latches 401 are engaged, the locking sleeve 400 secures the ferrule assembly 200 and the cable sheath 300. Figure 5 The locking sleeve 400 also includes an outwardly flared locking tongue 402, which is an elastic body. The end of the locking sleeve 400 opposite to the free end of the locking tongue 402 is a positioning end 403. When the positioning end 403 abuts against the positioning platform 111, the locking tongue 402 flips into the locking groove 112 and abuts against the side wall of the locking groove 112 facing the positioning platform 111. Thus, the positioning end 403 and the side wall of the locking groove 112 facing the positioning platform 111 can clamp the locking sleeve 400 towards each other, fixing the locking sleeve 400 relative to the housing assembly 100.

[0036] In the aforementioned assembled plug structure 10, the locking sleeve 400 is formed by the detachable snap-fit ​​of the snap flaps 401. When the snap flaps 401 are engaged, the locking sleeve 400 secures the ferrule assembly 200 and the wire sheath 300. Thus, by engaging multiple snap flaps 401, the locking sleeve 400, the ferrule assembly 200, and the wire sheath 300 can be assembled into a stable assembly. Furthermore, when the positioning end 403 abuts against the positioning platform 111, the locking tongue 402 flips into the locking groove 112 and abuts against the side wall of the locking groove 112 facing the positioning platform 111. In other words, the locking sleeve 400, relying on its locking tongue 402 and positioning end 403, can also be fixedly connected to the housing assembly 100, thereby ensuring the assembly is securely connected to the housing assembly 100. In this application, the engaging operation of the latch 401 of the locking sleeve 400, the insertion of the positioning end 403 into the housing assembly 100 and its abutment against the positioning platform 111, and the operation of the elastic locking tongue 402 flipping into the locking groove 112 and abutting against the groove wall of the locking groove 112 can all be achieved through simple manual operation. Therefore, the assembled plug-in structure 10 provided in this application does not rely on automated equipment during assembly and can be performed manually. Thus, the assembled plug-in structure 10 allows end users to easily adjust the wiring configuration according to actual needs and then assemble it themselves. At the same time, the assembled plug-in structure 10 can also be used for on-site self-assembly, which is highly operable and convenient.

[0037] It is easy to understand that in the various embodiments of this application, multiple semi-open latches 401 are engaged to form a complete locking sleeve 400. Since the locking sleeve 400 is located inside the housing assembly 100, the circumferential closing action of the housing assembly 100 can restrict the multiple latches 401 from separating from each other, so that the latches 401 remain engaged to stably fix the ferrule assembly 200 and the cable sheath 300.

[0038] Please see Figure 3 Combined Figure 6 and Figure 7In one embodiment, the ferrule assembly 200 includes a first adapter 210. The cable sheath 300 includes a second adapter 310. The locking sleeve 400 has a first connecting portion 405 and a second connecting portion 406, which are axially spaced apart. When the latch 401 is engaged, the first connecting portion 405 is fixedly connected to the first adapter 210, and the second connecting portion 406 is connected to the second adapter 310. One of the first adapter 210 and the first connecting portion 405 is configured as an annular groove, and the other is configured as a retaining ring. Similarly, one of the second adapter 310 and the second connecting portion 406 is configured as an annular groove, and the other is configured as a retaining ring. That is, when the semi-open latch 401 is engaged to form the complete locking sleeve 400, the retaining ring structure in the first connecting portion 405 and the first adapter 210 can be engaged into the annular groove structure to achieve fixation. The second connecting part 406 and the second adapter part 310 are configured as retaining rings, which can be engaged into the structure configured as a ring groove to achieve fixation. In this embodiment, the process of fastening the latch 401 is also the process of connecting and fixing the locking sleeve 400 to the ferrule assembly 200 and the wire sheath 300, which is simple to operate.

[0039] It is easy to understand that having too many latches 401 is not conducive to assembly. Therefore, in one embodiment, the number of latches 401 can be two, which can be referred to as the first latch 410 and the second latch 420, respectively. That is, the lock sleeve 400 includes the first latch 410 and the second latch 420, and the first latch 410 and the second latch 420 can be separably fastened to form the lock sleeve 400. Of course, the embodiments of this application do not limit the number of latches 401 to only two; the number of latches 401 can also be configured to three, four, five, etc.

[0040] Please see Figure 3 Combined Figure 6 and Figure 7 In one embodiment, at least one of the first latch 410 and the second latch 420 has a locking tongue 402. The first latch 410 includes a plurality of first ring portions 430, and the second latch 420 includes a plurality of second ring portions 440. Each first ring portion 430 and each second ring portion 440 is configured as either a groove or a protruding ring. After the first latch 410 and the second latch 420 are engaged, the plurality of first ring portions 430 and the plurality of second ring portions 440 are correspondingly enclosed to form a first connecting portion 405 and a second connecting portion 406. Further, the first ring portions 430 and the second ring portions 440 are configured as semi-circular shapes.

[0041] For example, when both the first connecting portion 405 and the second connecting portion 406 are constructed as retaining rings, both the first ring portion 430 and the second ring portion 440 are constructed as convex rings. When the first latch 410 and the second latch 420 are engaged, the first ring portion 430 and the second ring portion 440 are circumferentially joined to form a complete retaining ring-shaped first connecting portion 405 and second connecting portion 406, which engage with the first adapter portion 210 and the second adapter portion 310.

[0042] Similarly, when both the first connecting portion 405 and the second connecting portion 406 are constructed as annular grooves, both the first ring portion 430 and the second ring portion 440 are constructed as grooves. When the first latch 410 and the second latch 420 are engaged, the first ring portion 430 and the second ring portion 440 are circumferentially joined to form complete annular groove-shaped first connecting portion 405 and second connecting portion 406, which then engage with the first adapter portion 210 and the second adapter portion 310. Of course, the first connecting portion 405 and the second connecting portion 406 can be configured with different slot types, and the first ring portion 430 and the second ring portion 440 can be configured accordingly, which will not be described in detail here.

[0043] Furthermore, the number of the first ring portion 430 and the second ring portion 440 can each be two, correspondingly enclosing and forming the first connecting portion 405 and the second connecting portion 406. In this case, the number of the first connecting portion 405 and the second connecting portion 406 is one. Of course, the number of the first connecting portion 405 and the second connecting portion 406 can also be configured to other numbers according to requirements, and the number of the first ring portion 430 and the second ring portion 440 will be adjusted accordingly, which will not be elaborated here.

[0044] Please see Figure 5 Combined Figure 3 , Figure 6 and Figure 7 In one embodiment, the first connecting portion 405 and the second connecting portion 406 may be located at the two end regions of the locking sleeve 400, respectively, to connect the ferrule assembly 200 and the cable sheath 300.

[0045] In one embodiment, the locking sleeve 400 further includes locking pins 409, which are disposed on the inner wall surface of the locking sleeve 400, and the number of locking pins 409 is at least two. The cable sheath 300 has a locking hole 321. When the latch 401 is engaged, one of the locking pins 409 is inserted into the locking hole 321 to further improve the stability of the locking connection between the locking sleeve 400 and the cable sheath 300. At the same time, when the latch 401 is engaged, the other locking pin 409 is press-fitted into the ferrule assembly 200. Similar to the first connecting portion 405 and the second connecting portion 406, at least two locking pins 409 may also be located at the two end regions of the locking sleeve 400, respectively.

[0046] Please see Figure 5In one embodiment, the first connecting portion 405 can be configured as a retaining ring. The first connecting portion 405 is disposed on the inner peripheral surface of the locking sleeve 400, and extends to the intersection of the inner peripheral surface of the locking sleeve 400 and the end face of the positioning end 403, where the end face of the locking sleeve 400 abuts against the positioning platform 111. That is, in this embodiment, only a protruding area needs to be machined on the inner wall surface of the locking sleeve 400 near the positioning end 403 to achieve engagement with the ferrule assembly 200 and abutment against the positioning platform 111. This design, with a certain distance between the first connecting portion 405 and the end face of the positioning end 403, facilitates the manufacturing of the locking sleeve 400. Similarly, the second connecting portion 406 is also disposed on the inner peripheral surface of the locking sleeve 400, and extends to the end face of the locking sleeve 400 opposite to the positioning end 403 for easier manufacturing.

[0047] Please see Figure 6 , Figure 7 Combined Figure 3 In one embodiment, one of the first latching flap 410 and the second latching flap 420 includes a guide pin 407, and the other has a guide hole 408. When the first latching flap 410 and the second latching flap 420 are engaged, the guide pin 407 is inserted into the guide hole 408. Thus, during the engagement of the first latching flap 410 and the second latching flap 420, the guide pin 407 and the guide hole 408 can provide a docking and positioning effect, so that the first latching flap 410 and the second latching flap 420 are accurately aligned, which facilitates the accurate alignment of the first ring portion 430 and the second ring portion 440 to form the first connecting portion 405 and the second connecting portion 406.

[0048] Furthermore, the first latch 410 has a first mating surface 411. The second latch 420 has a second mating surface 421. One of the first mating surfaces 411 and 421 is provided with a guide pin 407, and the other is provided with a guide hole 408. When the first latch 410 and the second latch 420 are engaged, the first mating surface 411 and the second mating surface 421 are in contact, that is, the area where the first mating surface 411 and the second mating surface 421 are located is part of the solid structure of the lock sleeve 400. Therefore, the guide pin 407 and the guide hole 408 are respectively provided on the first mating surface 411 and the second mating surface 421. When the first latch 410 and the second latch 420 are engaged, the guide pin 407 and the guide hole 408 form the solid structure of the lock sleeve 400 in a fitting and plugging manner and are integrated into the solid structure of the lock sleeve 400, without occupying the internal cavity of the lock sleeve 400, which facilitates the arrangement of the ferrule assembly 200, the cable sheath 300, and the cable between them.

[0049] Please continue reading. Figure 6 and Figure 7In one embodiment, the number of guide pins 407 and guide holes 408 can both be multiple. Multiple guide pins 407 can be all located on the first mating surface 411, and multiple guide holes 408 can be correspondingly located on the second mating surface 421, and vice versa. Alternatively, some guide pins 407 can be located on the first mating surface 411, and some guide pins 407 can be located on the second mating surface 421; correspondingly, some guide holes 408 can be located on the first mating surface 411, and some guide holes 408 can be located on the second mating surface 421, with the multiple guide pins 407 and multiple guide holes 408 interleaved.

[0050] Please see Figure 5 In one embodiment, the housing assembly 100 includes a first housing 110 and a second housing 120, which are axially detachably connected. For example, the first housing 110 and the second housing 120 can be connected by a threaded connection. A portion of the second housing 120 is fitted over the first housing 110 for threaded connection. Further, a positioning platform 111 and a locking groove 112 are provided in the first housing 110, and the ferrule assembly 200 passes through the first housing 110. A cable sheath 300 passes through the second housing 120.

[0051] Please see Figure 5 Combined Figure 1 In one embodiment, the assembled plug structure 10 further includes a tail sleeve 500 and a flexible sleeve 600. The tail sleeve 500 is located on the side of the cable sheath 300 away from the ferrule assembly 200. The tail sleeve 500 is fitted over the cable sheath 300, and the cable inside the cable sheath 300 can extend and be distributed within the tail sleeve 500. The flexible sleeve 600 is fitted over the tail sleeve 500 and connected to the second housing 120. The flexible sleeve 600 is flexible and connects the relatively hard second housing 120 and the relatively soft tail sleeve 500, reducing the risk of damage to the tail sleeve 500 due to mutual wear between the tail sleeve 500 and the second housing 120.

[0052] Please see Figure 8 Combined Figure 5 In one embodiment, the cable sheath 300 includes a sheath body 320 and a snap-fit ​​ring 330. The snap-fit ​​ring 330 protrudes from the outer periphery of the sheath body 320, and the tail cable sheath 500 is fitted onto the cable sheath 300 and snapped into place by the snap-fit ​​ring 330. The snap-fit ​​connection improves the stability of the connection between the tail cable sheath 500 and the cable sheath 300 and reduces the risk of the tail cable sheath 500 falling off.

[0053] Please see Figure 5 In one embodiment, the first housing 110 can be directly fitted over the ferrule assembly 200 to axially support the ferrule assembly 200. However, for the cable sheath 300, because it is covered by structures such as the tail cable sheath 500, it is not convenient to directly and circumferentially support it through the second housing 120. Therefore, please refer to... Figure 8 Combined Figure 5 In one embodiment, the cable sheath 300 further includes a positioning disk 340, which protrudes from the sheath body 320. The tail end of the locking sleeve 400 abuts against the opposite sides of the positioning disk 340, respectively, with the locking sleeve 400 clamping the second housing 120 to further define the position of the cable sheath 300 and improve its positional stability. Furthermore, the outer periphery of the positioning disk 340 can also abut against the inner circumferential surface of the second housing 120, thus providing circumferential support for the cable sheath 300.

[0054] Please see Figure 5 In one embodiment, a limiting ring 121 protrudes from the inner circumferential surface of the second housing 120. The limiting ring 121 is located at the end of the second housing 120 that is relatively far away from the first housing 110. That is, the limiting ring 121 can be located on the side of the positioning disk 340 that is far away from the locking sleeve 400 and abut against the positioning disk 340. Thus, the limiting ring 121 can cooperate with the locking sleeve 400 to clamp and secure the protective sleeve 300.

[0055] Please see Figure 5 Combined Figure 8 and Figure 9 In one embodiment, the assembled plug structure 10 further includes a bushing 700. The two ends of the bushing 700 abut against the limiting ring 121 and the side of the positioning disk 340 away from the locking sleeve 400, respectively; that is, the limiting ring 121 can indirectly abut against the positioning disk 340 through the bushing 700. Further, the bushing 700 is fitted onto the tail wire sleeve 500. The bushing 700 includes a sleeve 710 and a pressure ring 720, the pressure ring 720 protruding from the inner wall surface of the end of the sleeve 710 away from the positioning disk 340. The snap-fit ​​ring 330 includes a wedge-shaped portion 331, located on the side of the snap-fit ​​ring 330 away from the positioning disk 340, and the size of the wedge-shaped portion 331 protruding from the sleeve body 320 gradually decreases in the direction away from the positioning disk 340. The pressure ring 720 and the wedge-shaped portion 331 are aligned to jointly clamp the tail wire sleeve 500, thereby improving the positional stability of the tail wire sleeve 500 relative to the protective sleeve 300. It is easy to understand that the tail wire sleeve 500 can be first fitted onto the protective sleeve 300, causing the tail wire sleeve 500 to engage with the snap-fit ​​ring 330. Then, the bushing 700 and the second housing 120 are sequentially inserted axially. The bushing 700 presses against the outer circumference of the tail wire sleeve 500 and, together with the snap-fit ​​ring 330, clamps the tail wire sleeve 500.

[0056] Please see Figure 5 Combined Figure 1 In one embodiment, a portion of the flexible sleeve 600 passes through the second housing 120 and is snapped into the second housing 120.

[0057] In one embodiment, the sheath 300 may be configured to be made of metal and is used to connect to and be electrically conductive with a grounding element, so that the sheath 300 can be used as a shielding ring.

[0058] It is understandable that the first housing 110, the second housing 120, the locking sleeve 400, and the wire protection sleeve 300 can all be configured as hollow tubular structures.

[0059] Please see Figure 4 In one embodiment, the ferrule assembly 200 includes an insulator 220 and terminals 230. The number of terminals 230 can be multiple, and the multiple terminals 230 are respectively disposed in the insulator 220.

[0060] In one embodiment, the assembled connector further includes a connector cap 800, which is fitted onto the housing assembly 100. The connector cap 800 is used for locking with another insertion structure included in the connector.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
