Description

Technical Field

[0001] This application relates to the field of fiber optic connector technology, and more particularly to a fiber optic connector that is easy to separate from the adapter in confined spaces. Background Technology

[0002] Fiber optic connectors allow for the splicing of fiber optic segments and the connection of optical cables and modules. This enables optical signals to form a continuous optical path between the cable, fiber, and module, thereby extending the transmission distance. Fiber optic connectors are typically paired with corresponding adapters to precisely align the two end faces of the fiber. For example... Figure 1 and Figure 2 The figures shown are fiber optic connectors for connecting one and two optical fibers in the prior art, respectively. Figure 1 and Figure 2 As can be seen, existing fiber optic connectors are held in place by a locking structure 1. When it is necessary to separate the fiber optic connector from the adapter, the locking structure 1 is disengaged by pressing the elastic buckle 2. In practical applications, for the sake of neatness and aesthetics, the mating fiber optic connectors and adapters are generally densely arranged, resulting in relatively narrow space allocated to each fiber optic connector, especially the space above the fiber optic connector. Thus, when the space above the fiber optic connector in existing technology is occupied, it is difficult for the user to press the elastic buckle, making the operation of separating the fiber optic connector from the adapter difficult and hindering the rapid separation of the fiber optic connector from the adapter.

[0003] Therefore, the existing technology needs to be further improved and enhanced. Utility Model Content

It should also be understood that terms such as those defined in general dictionaries should be understood as having meanings consistent with those in the prior art, and unless specifically defined as here, should not be interpreted as idealized or overly formal.

[0042] The prior art needs the user to press the locking structure on the fiber connector with hands to separate the fiber connector from the adapter, so when the space above the fiber connector is occupied, the operation difficulty of separating the fiber connector from the adapter will increase, and the quick separation of the fiber connector from the adapter cannot be realized. Therefore, the application discloses a fiber connector which can quickly separate from the adapter in a narrow space, wherein a buckle is arranged on the quick release part connected with the foot cover clamping, the buckle is clamped with the locking piece on the ferrule part by the clamping part guiding, the user only needs to pull the foot cover away from the adapter, so as to drive the locking piece to separate from the adapter, thereby realizing the separation of the fiber connector from the adapter, the operation is simple, and the separation of the fiber connector from the adapter can be quickly realized in a narrow space.

[0043] Specifically, as shown in Figure 3 and Figure 4 , the fiber connector comprises a ferrule part 100, a clamping part 200, a quick release part 300 and a foot cover 400, wherein the top of the ferrule part 100 is provided with a locking piece 101, the fiber connector is clamped and connected with the adapter through the locking piece 101; the ferrule part 100 is clamped and connected with the foot cover 400, the fiber passes through the foot cover 400 and is connected with the ferrule 130 in the ferrule part 100, so as to be connected with other fibers in the adapter through the ferrule 130; the quick release part 300 is clamped on the foot cover 400 and is provided with a buckle 320 extending along the horizontal direction towards the ferrule part 100, the buckle 320 is clamped with the locking piece 101 under the guidance of the clamping part 200 sleeved on the ferrule part 100, so that the user only needs to pull the foot cover 400 away from the ferrule part 100 (i.e. away from the adapter), so as to drive the locking piece 101 to separate from the adapter through the buckle 320, thereby realizing the separation of the fiber connector from the adapter, the operation is simple, and the separation of the fiber connector from the adapter can be quickly realized in a narrow space.

[0044] Further, as shown in Figure 4 , the ferrule part 100 comprises a first housing 110 and a second housing 120 which are detachably connected, the first housing 110 and the second housing 120 are connected to fix the ferrule 130 at the center position, so as to ensure that the ferrule 130 is matched and connected with the fiber in the adapter after the ferrule part 100 is connected with the adapter. Further, as shown in Figure 4As shown, the locking member 101 is fixedly arranged on the top of the first housing 110. Specifically, the first housing 110 is arranged towards the adapter, and the locking member 101 is fixedly arranged on the top of the first housing 110 and is inclined upwards towards the direction away from the adapter, so that the upper wall of the locking member 101 is clamped by the adapter when the first housing 110 of the ferrule portion 100 is inserted into the adapter, thereby achieving the connection between the fiber connector and the adapter.

[0045] Further, as shown in Figure 3 and Figure 4 the top end of the locking member 101 is provided with a hook 102, which is arranged perpendicularly to the locking member 101, so that when the buckle 320 is clamped by the locking member 101 under the guidance of the clamping portion 200, the hook 102 hooks the buckle 320 to achieve the stable connection between the buckle 320 and the locking member 101, and to ensure that when the buckle 320 moves away from the adapter along with the boot 400, the locking member 101 moves synchronously and is separated from the adapter, thereby achieving the separation between the fiber connector and the adapter.

[0046] Further, the second housing 120 is arranged towards the boot 400 and is clamped and connected with the boot 400 to receive the optical fiber passing through the boot 400. Specifically, the first housing 110 and the second housing 120 are both hollow structures with both ends open, and the first housing 110 and the second housing 120 are combined to clamp the ferrule 130 at the center position, and one end of the ferrule 130 is connected with the optical fiber passing through the boot 400 through the second housing 120, and the other end of the ferrule 130 is connected with the optical fiber in the adapter through the first housing 110, thereby connecting the two optical fibers together.

[0047] Optionally, the first housing 110 and the second housing 120 are clamped and connected. In an embodiment, the sidewall of the first housing 110 is provided with a housing clamping slot, and the sidewall of the second housing 120 is provided with a housing clamping protrusion corresponding to the housing clamping slot, and the clamping connection between the first housing 110 and the second housing 120 is achieved by the clamping of the housing clamping protrusion and the housing clamping slot. In an embodiment, the top of the first housing 110 is provided with a guide cutout, and the second housing 120 is provided with a guide protrusion corresponding to the guide cutout, and the matching of the guide protrusion and the guide cutout ensures that the first housing 110 and the second housing 120 are clamped and connected in a specific direction, thereby reducing the operation difficulty and improving the stability of installation.

[0048] Further, as shown in Figure 4As shown, the side wall of the second housing 120 is provided with a clamping slot 121 in the vertical direction to achieve clamping connection of the ferrule part 100 and the clamping part 200.

[0049] Further, as shown in FIG. 1, the clamping part 200 is provided with a clamping buckle 320 on the side wall of the clamping part 200, and the clamping buckle 320 is provided with a clamping slot 321 in the vertical direction to achieve clamping connection of the clamping part 200 and the adapter. Figure 3 As shown, the clamping part 200 is sleeved on one end of the ferrule part 100 close to the foot sleeve 400, and guides the clamping buckle 320 to be clamped with the clamping hook 102 on the locking piece 101. Specifically, the clamping part 200 is a ring structure and the inside of the clamping part 200 is adapted to the shape and size of the ferrule part 100 to ensure that the clamping part 200 can be stably sleeved on the ferrule part 100. Further, the inside of the clamping part 200 includes a first space 210 matching the ferrule part 100, and a second space 220 above the first space 210 matching the size of the clamping buckle 320. Specifically, the height of the second space 220 is less than the height of the clamping hook 102, so that the clamping buckle 320 needs to be bent upwards after passing through the second space 220 to be clamped with the clamping hook 102. When the foot sleeve 400 is pulled to move the clamping buckle 320 synchronously, the clamping hook 102 is forced to move downward, so that the upper surface of the locking piece 101 is separated from the adapter, achieving separation of the fiber connector and the adapter. Alternatively, the top side wall of the first space 210 is protruded to form the second space 220 with smaller transverse size, so that the size of the second space 220 is smaller than the size of the ferrule part 100, ensuring that the ferrule part 100 is fixed in the first space 210.

[0050] Further, as shown in FIG. 1, the clamping part 200 is provided with a clamping buckle 320 on the side wall of the clamping part 200, and the clamping buckle 320 is provided with a clamping slot 321 in the vertical direction to achieve clamping connection of the clamping part 200 and the adapter. Figure 5 As shown, the inside of the first space 210 is provided with a clamping protrusion 240 on the two side walls, and the clamping protrusion 240 is arranged corresponding to the clamping slot 121 to clamp the clamping protrusion 240 into the clamping slot 121 when the clamping part 200 is sleeved on the ferrule part 100, achieving fixed clamping of the clamping part 200 and the ferrule part 100 and ensuring the stability of the overall connection. Alternatively, the clamping part 200 is provided with a break to form a ring structure with an opening, to facilitate installation of the clamping part 200 on the ferrule part 100 and facilitate dismounting of the clamping part 200 from the ferrule part 100.

[0051] Further, as shown in FIG. 1, the clamping part 200 is provided with a clamping buckle 320 on the side wall of the clamping part 200, and the clamping buckle 320 is provided with a clamping slot 321 in the vertical direction to achieve clamping connection of the clamping part 200 and the adapter. Figure 4As shown, the quick release part 300 is clamped on the boot 400, wherein the quick release part 300 comprises a quick release part body 310 and the buckle 320 fixed on the top of the quick release part body 310. Wherein, the buckle 320 is a horizontally arranged buckle, and extends in the horizontal direction towards the direction of the ferrule part 100. Further, the buckle 320 is an elastic buckle, after the quick release part 300 is clamped on the boot 400, the buckle 320 passes through the clamping part 200 and is bent upwards to be buckled with the locking piece 101, realizing the clamping connection between the buckle 320 and the locking piece 101. Further, by hooking the buckle 320 on the hook 102 at the top end of the locking piece 101, when the buckle 320 moves away from the locking piece 101, it will automatically exert a downward force on the locking piece 101, thereby facilitating the upper surface of the locking piece 101 to separate from the adapter, thereby realizing the separation of the fiber connector and the adapter.

[0052] In an embodiment, as shown in Figure 4 and Figure 6 the quick release part body 310 extends in the vertical direction towards the boot 400 to form a pair of clamping arms 330, and the opposite sides of the pair of clamping arms 330 match the outer surface size of the boot 400, so as to clamp the boot 400 between the pair of clamping arms 330, realizing the clamping connection between the quick release part body 310 and the boot, thereby clamping the quick release part 300 on the boot 400.

[0053] Further, as shown in Figure 6 the opposite sides of the pair of clamping arms 330 are provided with clamping arm protrusions 331, which clamp the boot 400 to increase the connection stability between the quick release part 300 and the boot 400, and ensure that the boot 400 does not rotate relative to the quick release part 300 after the quick release part 300 is clamped on the boot 400. Specifically, as shown in Figure 4 the boot 400 is provided with a socket 440, which is a through hole and matches the size of the clamping arm protrusion 331, so that after the quick release part body 310 and the boot 400 are clamped, the clamping arm protrusion 331 is clamped into the socket 440, to ensure the stability of the quick release part 300 and the boot 400 after clamping. Further, as shown in Figure 6 the clamping arm protrusion 331 is provided with an arc-shaped notch 332, which corresponds to the shape of the optical fiber passing through the boot 400, so that after the clamping arm protrusion 331 is clamped into the socket 440, the arc-shaped notch 332 fits the optical fiber and does not cause extrusion to the optical fiber, which not only ensures the stability of the optical fiber in the boot 400, but also avoids damage to the optical fiber.

[0054] Further, as shown in Figure 4 The sleeve 400 is a hollow cylindrical structure, and a plurality of cuts 420 are arranged on the surface of the sleeve 400 in the radial direction. Each cut 420 extends in the circumferential direction of the sleeve 400 and forms a rib 430 between adjacent cuts 420. The cuts 420 are used to form the ribs 430 on the surface of the sleeve 400, thereby increasing the friction of the surface of the sleeve 400, so that the user can more conveniently pull the sleeve 400 to separate the fiber connector from the adapter.

[0055] In one embodiment, as shown in Figure 4 The sleeve 400 further comprises a fiber sleeve 410, which is arranged inside the sleeve 400 and is connected to the second housing 120 of the ferrule portion 100 at one end. The fiber passes through the fiber sleeve 410 to connect the ferrule 130 in the ferrule portion 100 and the sleeve 400.

[0056] Therefore, the fiber connector disclosed in the present application is provided with a specific structure, so that the user only needs to pull the sleeve to move away from the adapter, thereby achieving the separation of the fiber connector from the adapter. Even in a narrow space, the separation operation can be conveniently and quickly performed.

[0057] In actual application, there are often cases where multiple fibers need to be connected in parallel. For multiple fibers, the fiber connector disclosed in the present application can also achieve quick separation from the adapter. Taking the use of two fibers as an example, the following will describe the variant of the fiber connector disclosed in the present application in combination with specific embodiments. The arrangement of the ferrule portion 100 and the sleeve 400 remains unchanged, and only the corresponding number of ferrule portions 100 and sleeves 400 are added according to the number of fibers, and the specific arrangement will not be repeated.

[0058] In the first embodiment, as shown in Figure 8 and Figure 9 For two fibers, two clamping portions 200 are used to be arranged on the corresponding ferrule portions 100. At this time, two parallel buckles 320 are formed on the quick release portion 300 corresponding to the clamping portions 200, so as to pass through the corresponding clamping portions 200 and be clamped with the locking members 101 on the corresponding ferrule portions 100 under the guidance of the clamping portions 200, thereby ensuring that when the sleeve 400 is pulled, the buckles 320 simultaneously move the locking members 101 on the two ferrule portions 100, so that the two locking members 101 simultaneously separate from the adapter, thereby achieving the separation of the fiber connector from the adapter.

[0059] Further, in the present embodiment, as shown in Figure 7As shown, two pairs of clamping arms 330 are formed on the quick release part body 310 of the quick release part 300, and the clamping arms of each pair are opposite to each other, and the adjacent clamping arms of the two pairs are integrally formed back to back and arranged corresponding to the gap between the two foot sleeves 400, so as to clamp the two foot sleeves 400 between the two pairs of clamping arms 330 respectively. Further, the clamping arms 330 are provided unchanged, and the clamping arm protrusions 331 are also provided to match the clamping holes 440 on the foot sleeve 400, so as to ensure that the foot sleeve 400 will not rotate after being clamped between the corresponding pair of clamping arms 330. At the same time, the clamping arm protrusions 331 are provided with arc-shaped cutouts 332, so as to avoid damaging the optical fiber in the foot sleeve 400.

[0060] In the second embodiment, the clamping part 200 is replaced, and a clamping part 200 is used to cover two ferrule parts 100 and guide the buckles 320 to be clamped with the locking members 101 on the ferrule parts 100. Specifically, as shown in the figure, Figure 10 As shown, a partition wall 230 is arranged inside the clamping part 200, and the partition wall 230 is arranged at the middle position of the clamping part 200, and divides the first space 210 in the clamping part 200 into two symmetrical first subspaces 211, and divides the second space 220 into two symmetrical second subspaces 221. Among them, the first subspaces 211 correspond to one ferrule part 100 respectively, so as to cover two ferrule parts 100 through the two first subspaces 211 respectively; the second subspaces 221 correspond to one buckle 320 respectively, so as to guide the buckles 320 to be clamped with the locking members 101 on the corresponding ferrule parts 100 through the two second subspaces 221 respectively, so as to ensure that when the foot sleeve 400 is pulled, the buckles 320 simultaneously drive the locking members 101 on the two ferrule parts 100 to move, so that the two locking members 101 simultaneously separate from the adapter, so as to realize the separation of the optical fiber connector and the adapter.

[0061] Further, in this embodiment, the top inner wall of each first subspace 211 is inwardly protruded to form the second subspace 221, so as to ensure that the corresponding ferrule part 100 is covered and fixed in the first subspace 211; the inner wall of each first subspace 211 is provided with a clamping protrusion 240, so as to match with the clamping groove 121 on the second housing 120 of the corresponding ferrule part 100, so as to ensure the clamping stability of the clamping part 200 and the two ferrule parts 100.

[0062] Further, in this embodiment, the quick release part 300 uses the structure as shown in the figure, Figure 7As shown in the setting, two buckles 320 are arranged in parallel, and the buckles 320 correspond to two second subspaces 221 in the clamping part 200 respectively, so as to be clamped with the corresponding locking pieces 101 on the ferrule part 100 under the guidance of the second subspaces 221. Further, two pairs of clamping arms 330 are formed on the quick release part body 310, and the two pairs of clamping arms 330 are opposite to each other, and the adjacent clamping arms between the two pairs of clamping arms 330 are integrally formed back to back, and are arranged corresponding to the gap between the two booties 400, so as to clamp the two booties 400 between the two pairs of clamping arms 330 respectively, so as to ensure that after the booties 400 are pulled, the two buckles 320 synchronously drive the locking pieces 101 on the two ferrule parts 100 to move, so that the two locking pieces 101 are simultaneously separated from the adapter, and the optical fiber connector is separated from the adapter.

[0063] In the third embodiment, as shown in Figure 11 and Figure 12 , the clamping part 200 with the same setting as in the second embodiment is used to replace the setting of the quick release part 300. Specifically, the clamping part 200 forms two first subspaces 211 and two second subspaces 221 through the partition wall 230, so that the clamping part 200 can be simultaneously sleeved on two ferrule parts 100 and guide two buckles 320 to be clamped with the corresponding locking pieces 101 on the ferrule part 100. Further, as shown in Figure 13 , two buckles 320 are arranged in parallel on the quick release part 300, and the quick release part body 310 forms a clamping arm 330 away from the ferrule part 100 in the horizontal direction, which is arranged corresponding to the gap between the two booties 400 to clamp the clamping arm 330 between the two booties 400, so as to realize the clamping connection between the quick release part body 310 and the booties 400. Specifically, as shown in Figure 11 and Figure 12 , the clamping arm 330 includes an insertion part 333, a platform part 334 and a protruding rib 335, wherein the insertion part 333 is a wedge-shaped structure and is arranged corresponding to the gap between the two booties 400 to be inserted between the two booties 400; the platform part 334 is arranged on the top of the insertion part 333 and is arranged in the horizontal direction to cover the surfaces of the two booties 400; and the protruding rib 335 is arranged vertically on the platform part 334 to provide a force point when a user wants to pull the booties 400, so as to facilitate the user to pull the booties 400 away from the adapter, thereby driving the locking pieces 101 to be separated from the adapter through the buckles 320, so as to realize the separation of the optical fiber connector and the adapter, which is simple to operate and can quickly realize the separation of the optical fiber connector and the adapter even in a narrow space.

[0064] The mechanism of the fiber connector of the present application when separated from the adapter is described below in conjunction with the accompanying drawings.

[0065] As shown in Figure 14 When the fiber connector of the present application is connected with the adapter 1000, the optical fiber 500 is connected with the ferrule 130 in the ferrule part 100 through the fiber sleeve 410 and the foot sleeve 400, and is connected with the optical fiber in the adapter 1000 through the ferrule 130. At this time, the locking member 101 on the ferrule part 100 is clamped and fixed with the adapter 1000, realizing the fixed connection of the fiber connector with the adapter 1000. At this time, the buckle 320 on the quick release part 300 is buckled with the locking member 101 after passing through the clamping part 200. Under the guidance of the clamping part 200, the buckle 320 first extends downward and then bends upward to hook the clamping hook 102 at the top end of the locking member 101. As shown in Figure 15 When it is needed to separate the fiber connector from the adapter 1000, only the foot sleeve 400 needs to be pulled away from the adapter 1000 (to the right in the figure), at this time, the buckle 320 synchronously moves to the right with the quick release part 300 following the foot sleeve 400, the buckle 320 hooks the clamping hook 102 and moves the locking member 101, at this time, under the guidance of the clamping part 200, the buckle 320 needs to first move downward and then move to the right, thereby applying downward pressure to the locking member 101, so that the locking member 101 is separated from the adapter 1000, thereby realizing the separation of the fiber connector from the adapter and separating the ferrule 130 from the optical fiber in the adapter 1000. Since only the fiber connector needs to be pulled horizontally, even in the case of very narrow space around the fiber connector, the separation of the fiber connector from the adapter can still be easily and quickly realized, and the operation is simple and easy to apply.

[0066] In summary, the application provides an optical fiber connector, comprising a ferrule part, a foot sleeve, a clamping part and a quick release part. The ferrule part is sleeved with a ferrule to connect an optical fiber, and the top of the ferrule part is provided with a locking piece, and the optical fiber connector is clamped and connected with an adapter through the locking piece. The foot sleeve is clamped with the ferrule part, and the optical fiber is connected with the ferrule in the ferrule part through the foot sleeve. The clamping part is sleeved on one end of the ferrule part close to the foot sleeve, and the clamping part comprises a first space matched with the ferrule part and a second space arranged above the first space. The quick release part comprises a quick release part body and a buckle horizontally arranged on the top of the quick release part body. The quick release part body is clamped with the foot sleeve, and the buckle is clamped with the locking piece on the ferrule part through the second space of the clamping part, so that when the foot sleeve moves away from the adapter, the buckle drives the locking piece to separate from the adapter, and the separation of the optical fiber connector and the adapter is realized. By arranging the buckle on the quick release part clamped with the foot sleeve, the buckle is clamped with the locking piece on the ferrule part by the clamping part, and the user only needs to pull the foot sleeve away from the adapter to drive the locking piece to separate from the adapter, so as to realize the separation of the optical fiber connector and the adapter. The operation is simple, and the separation of the optical fiber connector and the adapter can be quickly realized even in a narrow space.

[0067] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
