Description

Technical Field

[0001] The present invention relates to the technical field of optical communication, and in particular to an easily detachable optical fiber connector and a disassembly method thereof. Background Art

[0002] LC Uniboot fiber optic connector, also called LC Uniboot fiber optic patch cord, is designed for high-density data center environment applications. It is superior to traditional Lucent Connector (LC) fiber optic patch cords in high-density wiring environments. Compared with standard patch cords, the design of LC Uniboot fiber optic patch cords is more optimized. It is a duplex connector that terminates two single optical fibers into the same sheath, which can effectively reduce the cable management space. Therefore, LC Uniboot fiber optic connector is the preferred choice for high-density data center connections.

Therefore, they should not be understood as limitations on the present invention.

[0041] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] It should be noted that, if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, all within the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms and directions used in this specification are only for the purpose of describing specific implementation methods and are not intended to limit the present invention.

[0043] In existing high-density data centers, the number of fiber optic connectors is huge, the layout is complicated, and the spacing between adjacent fiber optic connectors is extremely small. Therefore, in high-density scenarios, it may be impossible to press the duplex clamp to unlock the connector; for this situation, the existing technology has not yet found a good solution. In addition, when the polarity of the existing fiber optic connector needs to be changed, the fiber optic connector needs to be completely disassembled, and the connector head needs to be taken out and then exchanged, or the connector head needs to be rotated to achieve the purpose of reverse rotation, which is not only inconvenient to operate, but also has the possibility of damaging the optical fiber during the operation.

[0044] In order to solve the above problems, an embodiment of the present invention provides an easily detachable optical fiber connector and a disassembly method thereof. Through the design of the pull rod structure and the protruding structure on the duplex clamp, when the pull rod moves backward, the duplex clamp moves downward, thereby unlocking the connector. Based on this, in a high-density scenario, when the fingers cannot press the duplex clamp to unlock the connector, the connector can be unlocked by pulling the pull rod, which is convenient for removing the connector from the optical module interface or the optical fiber adapter interface, and convenient for subsequent maintenance of the optical fiber connector. Furthermore, the upper and lower shells of the connector are set as the same part, which cooperate with each other, which is convenient for manufacturing control and material control. The duplex clamp is fixed to the connector shell by a buckle. When changing the polarity, it is only necessary to remove the duplex clamp, then flip the shell and install the duplex clamp to achieve polarity interchange. The operation is convenient, simple and fast; and there is no need to disassemble the entire connector, so as to avoid exposure of the internal structure and reduce the chance of human damage.

[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] Example 1

[0047] refer to Figure 1 As shown, embodiment 1 of the present invention provides an easily detachable optical fiber connector, comprising a pull rod structure 1, a duplex clamp 2 and a connector body 3, wherein the duplex clamp 2 is detachably connected to the connector body 3, and the pull rod structure 1 is detachably connected to the duplex clamp 2. Figure 2 and Figure 3 As shown, the duplex clamp 2 includes a base 201 and an elastic clamp body 202 arranged on the base 201, a protruding structure 203 is arranged in the middle of the elastic clamp body 202, and a first limiting space 204 is arranged at the end of the elastic clamp body 202; the pull rod structure 1 includes a long-handled pull rod 101 and a clamping plate 102 arranged at the front end of the long-handled pull rod 101, and a clamping hole 103 corresponding to the protruding structure 203 is arranged on the clamping plate 102, referring to Figure 4 As shown, the bottom surface of the clamping plate 102 is provided with a first limiting block 104 corresponding to the first limiting space 204. Through the design of the clamping hole 103 and the protruding structure 203, when the pull rod structure 1 is displaced forward and backward relative to the duplex clamp 2, the duplex clamp 2 is driven to move downward, thereby unlocking the duplex clamp 2 and the optical module interface or the optical fiber adapter, and then the entire optical fiber connector can be easily disassembled from the optical module interface or the optical fiber adapter. Through the design of the first limiting block 104 and the first limiting space 204, the forward and backward displacement of the pull rod structure 1 relative to the duplex clamp 2 can be limited to prevent the pull rod structure 1 from detaching from the duplex clamp 2 and escaping alone when being pulled.

[0048] Through the design of the above-mentioned pull rod structure 1 and the protruding structure 203 on the duplex clamp 2, when the pull rod structure 1 moves backward, the duplex clamp 2 moves downward, thereby unlocking the connector. Based on this, in a high-density scenario, when the fingers cannot press the duplex clamp 2 to unlock the connector, the connector can be unlocked by pulling the pull rod structure 1, which facilitates the removal of the connector from the optical module interface or the optical fiber adapter, and also facilitates the subsequent maintenance of the optical fiber port or adjustment of the polarity.

[0049] In some embodiments, the top surface of the protruding structure 203 is arranged parallel to the horizontal plane, and the two side surfaces of the protruding structure 203 are arranged obliquely to the horizontal plane to form a trapezoidal cross section. With this arrangement, the pull rod structure 1 can be moved forward and backward more smoothly, and the duplex clamp 2 can be pressed down conveniently.

[0050] Specifically, refer to Figure 3As shown, in some embodiments, the elastic clamp body 202 includes two arms, a protruding structure 203 is provided in the middle of each arm, and a first limiting space 204 is provided on the outer side of each end of the arm. In some embodiments, a second limiting block 205 is provided at the front end of the first limiting space 204, and a third limiting block 206 is provided at the end of the first limiting space 204, and the first limiting space 204 is formed between the second limiting block 205 and the third limiting block 206. The side of the third limiting block 206 close to the first limiting space 204 is perpendicularly arranged with the side wall, and the side of the third limiting block 206 away from the first limiting space 204 is inclined with the side wall, and the inclination direction is toward the first limiting space 204. Reference Figure 4 As shown, the end of the first limit block 104 is perpendicular to the side wall, and the front end of the first limit block 104 is inclined to the side wall, and the inclination angle is consistent with the inclination angle of the third limit block 206 away from the first limit space 204. In this way, the pull rod structure 1 can be pushed along the end of the duplex clamp 2 to the front end, corresponding to Figure 3 In the process of pushing from left to right, the inclined surface of the first limit block 104 first contacts the inclined surface of the third limit block 206. At this time, continuing to push to the right can make the first limit block 104 enter the first limit space 204. After the first limit block 104 enters the first limit space 204, it will be limited by the second limit block 205 if it continues to push forward a certain distance. If it is pulled back, it will not be able to be pulled out further when it is pulled to the vertical surface of the third limit block 206, thereby achieving the purpose of limiting the first limit block 104 in the first limit space 204. The schematic diagram of the pull rod structure 1 and the duplex clamp 2 after being connected with each other is shown in FIG. Figure 7 As shown. Through the above arrangement, the pull rod structure 1 can be used to conveniently drive the duplex clamp 2 to be inserted into or removed from the optical module interface or the optical fiber adapter interface, and because of the front and rear limit positions, the pull rod structure 1 can be prevented from being separated from the duplex clamp 2 and then being removed alone. In addition, the long handle pull rod 101 of the pull rod structure 1 is set relatively long, so that its end is far away from the duplex clamp 2, which is convenient for unlocking the connector by pulling the pull rod structure 1 when the fingers cannot press the duplex clamp 2.

[0051] refer to Figure 5 As shown, a second card slot 401 is provided inside the optical fiber adapter interface 4. Figure 3As shown, in some embodiments, the front end of the elastic clamp body 202 is provided with a second elastic sheet 209 tilted downward, and the rear of the second elastic sheet 209 is provided with a second protrusion 210 corresponding to the second card slot 401 in the optical fiber adapter interface 4. Specifically, a second elastic sheet 209 is provided at the front end of each of the two arms of the elastic clamp body 202, and second protrusions 210 are provided on both sides of the rear of each second elastic sheet 209. Correspondingly, the optical fiber adapter interface 4 is provided with the same number of second card slots 401 as the second protrusions 210. Figure 3 , Figure 5 and Figure 6 As shown, when inserting, the optical fiber connector is inserted into the optical fiber adapter interface 4 as a whole, and when the second protrusion 210 reaches the second card slot 401, the locking connection between the optical fiber connector and the optical fiber adapter interface 4 is completed. When the optical fiber connector and the optical fiber adapter interface 4 need to be unlocked, the pull rod structure 1 is pulled outward to move the duplex clamp 2 downward, that is, the second protrusion 210 moves downward, and when the second protrusion 210 leaves the second card slot 401, the unlocking is completed, and the pull rod structure 1 is continued to be pulled to make the optical fiber connector withdraw from the optical fiber adapter interface 4 as a whole. In some embodiments, the front end of the second elastic sheet 209 is arc-shaped, so that the insertion process of the optical fiber connector is smoother.

[0052] refer to Figure 3 and Figure 4 As shown, in some embodiments, the bottom surface of the clamping plate 102 is provided with a second limiting space 105, and the base 201 is provided with a fourth limiting block 207 corresponding to the second limiting space 105; the second limiting space 105 is provided with fifth limiting blocks 106 on both sides, the width of the second limiting space 105 is consistent with the width of the fourth limiting block 207, and the distance between the two fifth limiting blocks 106 is smaller than the width of the fourth limiting block 207. In the process of inserting the tie rod structure 1 from left to right into the duplex clamp 2, the fourth limiting block 207 will gradually enter the second limiting space 105, and because of the above-mentioned size design, the tie rod structure 1 is limited in the vertical direction as a whole, avoiding the problem that the tie rod structure 1 is disengaged from the top of the duplex clamp 2 during normal operation. When the tie rod structure 1 and the duplex clamp 2 need to be disassembled, the tie rod structure 1 is pulled back until the fourth limiting block 207 is out of the range of the second limiting space 105, and the tie rod structure 1 can be taken out upward. In some embodiments, the second limiting space 105 is located in the middle of the bottom surface of the clamping plate 102, and the fourth limiting block 207 is located in the middle gap of the elastic clamp body 202; the second limiting space 105 and the fourth limiting block 207 are both arranged in the middle position, which can enhance the limiting effect and prevent the pull rod structure 1 from tipping upward.

[0053] refer to Figure 8As shown, in some embodiments, the connector body 3 includes a connector head 301, a connector tail 302, and a connector housing 303 disposed between the connector head 301 and the connector tail 302. Fig. 9 As shown, the connector housing 303 includes two identical sub-housings 304, one side of the sub-housing 304 is provided with a plurality of buckles 305, and the other side of the sub-housing 304 is provided with a plurality of snap rings 306, and the two sub-housings 304 are docked through the cooperation of the buckles 305 and the snap rings 306. For example, two snap rings 306 are provided on one side of each sub-housing 304, and two buckles 305 are provided on the other side opposite to each other, and the two sub-housings 304 are docked toward each other, and the connection and fixation can be completed through the cooperation of the buckles 305 and the snap rings 306. After the two sub-housings 304 are closed and fixed, the optical fiber is enclosed inside the housing, which can protect the optical fiber.

[0054] refer to Fig. 9 As shown, in some embodiments, a third limiting space 307 is provided in the middle of the upper surface of the sub-housing 304, and the width of the third limiting space 307 is consistent with the width of the base 201; a first elastic sheet 308 is provided above the third limiting space 307, and a first slot 309 is provided in the middle of the first elastic sheet 308. Figure 3 As shown, the base 201 is provided with a first protrusion 208 corresponding to the first slot 309 in the middle, the outer side of the first protrusion 208 is perpendicular to the horizontal plane, and the inner side of the first protrusion 208 is inclined to the horizontal plane, and the inclined side serves to facilitate pushing. Fig.10 As shown, when connecting the duplex clip 2 and the connector body 3, the base 201 of the duplex clip 2 is pushed inward along the third limiting space 307 on the connector body 3. When the base 201 is completely pushed into the third limiting space 307, the first protrusion 208 is also pushed into the first slot 309. Because the outer side of the first protrusion 208 is perpendicular to the horizontal plane, the first protrusion 208 cannot be pulled out of the first slot 309 by dragging the duplex clip 2 outward at this time, thus completing the locking connection between the duplex clip 2 and the connector body 3. When it is necessary to disassemble the duplex clip 2 and the connector body 3, the first elastic sheet 308 is pushed upward to make the first protrusion 208 leave the first slot 309. At this time, the duplex clip 2 is pushed outward again until the base 201 of the duplex clip 2 is completely separated from the third limiting space 307. The unlocking is completed, and the duplex clip 2 can be removed from the connector body 3. In the above process, the duplex clip 2 can be first formed into a whole with the pull rod structure 1, and then installed or removed with the connector body 3.

[0055] refer to Fig.11As shown, two polarities AA and AB are schematically shown, which is also the need for changing polarity. Based on the above arrangement of this embodiment, when the polarity needs to be changed, it is only necessary to remove the duplex clip 2 from the connector body 3, and then flip the connector body 3 on one side, that is, flip the previous bottom surface to the top surface, and then install the duplex clip 2 to the new top surface to complete the polarity change. The operation is simple and fast.

[0056] refer to Fig.12 and Fig.13 As shown, a first mark 310 and a second mark 311 are set on the top and bottom surfaces of the connector head 301, and whether the polarity has been changed can be judged from the marks on the connector head 301. Assuming that the duplex clamp 2 is installed on the front side with the first mark 310 (for example, 0), it means that the polarity has not been changed, and when the duplex clamp 2 is installed on the back side with the second mark 311 (for example, 1), it means that the polarity has been changed. In this way, it is easy and good to distinguish whether the product has changed polarity. In actual application, it can also be distinguished and identified by printing different colors on the front and back, such as printing white on the front and black on the back.

[0057] Through the above-mentioned arrangement, the embodiment of the present invention has the following advantages over the prior art: the prior art needs to completely disassemble the connector when changing polarity, and take out the optical fiber and then exchange the position, or rotate the front connector to achieve the purpose of reversing, and there is a possibility of damaging the optical fiber during the operation. When changing polarity, the embodiment of the present invention only needs to remove the parts consisting of the pull rod structure 1 and the duplex clamp 2, and there is no need to disassemble the entire connector, which can avoid the exposure of the internal structure, reduce the probability of human damage, and make the polarity change operation more convenient and quick. The prior art uses many parts, which increases the difficulty of manufacturing and is not convenient for parts management and size control. The cover and the base of the embodiment of the present invention are the same part, that is, both are sub-housings 304. When there is only one part, they are arranged by cooperating with each other, which is convenient for manufacturing control and material control.

[0058] In summary, the embodiments of the present invention provide an easily detachable optical fiber connector. Through the design of the pull rod structure and the protruding structure on the duplex clamp, when the pull rod moves backward, the duplex clamp moves downward, thereby unlocking the connector. Based on this, in a high-density scenario, when the fingers cannot press the duplex clamp to unlock the connector, the pull rod can be pulled to unlock the connector, which facilitates the removal of the connector from the optical module interface or the optical fiber adapter interface and facilitates subsequent maintenance of the optical fiber connector.

[0059] Furthermore, the upper and lower shells of the connector are configured as the same part, and they cooperate with each other, which is convenient for manufacturing control and material control. The duplex clamp is fixed to the connector shell by a buckle. When changing the polarity, you only need to remove the duplex clamp, then turn the shell over and install the duplex clamp to achieve polarity exchange. The operation is convenient, simple and fast; and there is no need to disassemble the entire connector, which avoids exposing the internal structure and reduces the chance of human damage.

[0060] Example 2

[0061] refer to Fig.14 As shown, this embodiment provides a method for disassembling an easily detachable optical fiber connector, which is applied to the easily detachable optical fiber connector described in Example 1, and the method includes the following steps.

[0062] Step 100: Pull the long handle pull rod 101 backwards, and the elastic clamp body 202 moves downwards through the cooperation between the clamping hole 103 and the protruding structure 203.

[0063] Step 200 : The elastic clip body 202 moves downward to drive the second protrusion 210 to withdraw from the second slot 401 .

[0064] Step 300 : Continue to pull the long-handled pull rod 101 backwards, so as to drive the pull rod structure 1 , the duplex clamp 2 and the connector body 3 to withdraw from the fiber optic adapter interface 4 as a whole.

[0065] In addition, the method of disassembling the pull rod structure 1, the duplex clamp 2 and the connector body 3 is also simple and convenient. When the polarity needs to be changed, the first elastic sheet 308 on the connector body 3 only needs to be pushed upward to remove the entirety of the pull rod structure 1 and the duplex clamp 2 from the connector body 3. After turning the connector body 3 over, the pull rod structure 1 and the duplex clamp 2 can be reinstalled to complete the polarity change.

[0066] The detailed structure of each component in the above method has been described in Example 1 and will not be repeated here.

[0067] In summary, the embodiments of the present invention provide a method for disassembling an easily detachable optical fiber connector. Through the design of the pull rod structure and the protruding structure on the duplex clamp, when the pull rod moves backward, the duplex clamp moves downward, thereby unlocking the connector. Based on this, in a high-density scenario, when the fingers cannot press the duplex clamp to unlock the connector, the pull rod can be pulled to unlock the connector, thereby facilitating the removal of the connector from the optical module interface or the optical fiber adapter interface and facilitating subsequent maintenance of the optical fiber connector.

[0068] Furthermore, the upper and lower shells of the connector are configured as the same part, and they cooperate with each other, which is convenient for manufacturing control and material control. The duplex clamp is fixed to the connector shell by a buckle. When changing the polarity, you only need to remove the duplex clamp, then turn the shell over and install the duplex clamp to achieve polarity exchange. The operation is convenient, simple and fast; and there is no need to disassemble the entire connector, which avoids exposing the internal structure and reduces the chance of human damage.
