Description

Technical Field

[0001] This invention relates to the field of fiber optic connector technology, and in particular to an LC type fiber optic connector. Background Technology

[0002] The LC type fiber optic connector is a miniaturized fiber optic active connector that adopts a modular jack latching mechanism. With its excellent performance such as high density, low insertion loss, and high return loss, it has become the mainstream connector type in data centers, fiber-to-the-home, and high-density fiber optic distribution networks.

[0003] Most existing LC-type fiber optic connectors adopt the structural form given in the communication industry standard YD / T1272.1-2018 "Fiber Optic Connectors - Part 1: LC Type". The core of the locking and unlocking mechanism of a typical LC-type connector specified in this standard lies in a resilient locking arm integrated into one side of the connector body along its thickness. The front of the resilient locking arm is connected to the connector body, the middle of the arm has a latch, and the rear of the arm is suspended. To facilitate compression of the rear of the resilient locking arm, thereby unlocking it, a pressing arm is also provided on the connector body. The pressing arm, the resilient locking arm, and the connector body form a triangular structure. When the connector needs to be removed, the operator must press the pressing arm with their fingers, causing the pressing arm to press against the rear of the resilient locking arm, thus unlocking it.

[0004] Existing LC-type fiber optic connectors must allow sufficient space for finger operation in the thickness direction. Therefore, a large gap must be maintained between adjacent connectors in the thickness direction to accommodate finger pressing motions. This requirement limits the installation space requirements of LC-type fiber optic connectors in the thickness direction, making them unsuitable for applications where installation space in the thickness direction of the fiber optic connector is limited. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this application is to provide an LC-type fiber optic connector that reduces the installation space requirements of the LC-type fiber optic connector in the thickness direction. The LC-type fiber optic connector of this application includes: The connector body has a thickness direction and a width direction, and in the thickness direction, the connector body has a first side; A flexible clamp arm, the front of which is connected to the first side, and the rear of which is suspended, is used to clamp an optical fiber adapter. A swing member, the middle part of which is hinged to the first side, the front end of which abuts against the rear part of the elastic locking arm, and the rear end of which has a trigger part, the trigger part being arranged on at least one side of the connector body in the width direction; Applying force to the trigger part can drive the swing member to rotate, causing the front end of the swing member to push the rear part of the elastic locking arm towards the first side, thereby disengaging the elastic locking arm from the fiber optic adapter.

[0006] As an optional solution, the LC type fiber optic connector also includes a tail sleeve, which is used to slide on the outside of the fiber. The front part of the tail sleeve is connected to the trigger part for transmission. Pulling the tail sleeve backward can drive the swinging member to swing, so that the elastic locking arm and the fiber optic adapter are released from the lock.

[0007] As an optional solution, the LC type fiber optic connector further includes a transmission component, the rear of which is connected to the tail sleeve; the front of the transmission component is slidably connected to one side of the connector body in the width direction, the front of the transmission component has a stop portion that blocks the trigger portion from the front and back, one of the stop portion and the trigger portion is provided with a slope that is inclined from the front and back, and the other slides against the slope.

[0008] As an optional solution, there are two triggering parts, both of which are connected to the rear end of the swing member, and the two triggering parts are respectively arranged on both sides of the connector body in the width direction; The connector body has mounting grooves extending in the front-rear direction on both sides in the width direction; there are two transmission components, one of which has its front part slidably disposed in one of the mounting grooves, and the other of which has its front part slidably disposed in the other mounting groove. The front part of the tail sleeve connects to the rear parts of the two transmission components.

[0009] As an optional solution, the rear of both transmission components has a limiting portion; in the front-rear direction, both limiting portions are arranged at intervals from the connector body, forming a limiting space between the two limiting portions and the connector body; The tail sleeve includes a tail sleeve body and an outer flange disposed at the front end of the tail sleeve body. The outer flange is disposed in the limiting space, and the two limiting parts stop the outer flange from the front and rear.

[0010] As an optional solution, each of the two limiting parts is provided with a limiting groove on an opposite side in the width direction to form a positioning channel between the two limiting parts; the tail sleeve body passes through the positioning channel.

[0011] As an optional solution, the transmission component includes a connecting part, the front part of which is slidably disposed in the mounting groove and connected to the stop part, and the rear part of which is connected to the limiting part; In the width direction, guide grooves are provided on both sides of the outer flange, one of the two connecting parts is slidably disposed in one of the guide grooves, and the other of the two connecting parts is slidably disposed in the other guide groove.

[0012] As an optional solution, the connector body includes a shell body, a cover body, and a center sleeve. The cover body is detachably connected to one side of the shell body in the thickness direction. The rear sidewall of the shell body has a first slot that extends through the rear sidewall of the shell body from front to back. The rear sidewall of the shell body has a first opening on the side facing the cover body. The first opening is configured to allow the center sleeve to enter the first slot along the thickness direction. When the cover is connected to the shell body, it can block the first slot to prevent the central sleeve from coming out of the first slot; the tail sleeve is slidably sleeved on the outside of the central sleeve.

[0013] As an optional solution, the connector body includes a shell body and a cover body, the cover body being detachably connected to one side of the shell body in the thickness direction; the swing member is hinged to the cover body via a pivot. The cover has a first mounting hole extending along the width direction on the side opposite to the shell body. The rotating shaft passes through the first mounting hole. The side of the shell body connected to the cover has a stop protrusion. When the cover is connected to the shell body, the stop protrusion stops the rotating shaft in the width direction to prevent the rotating shaft from coming out of the mounting hole.

[0014] As an alternative, the connector body has a recess on at least one side in the width direction, and the trigger portion is disposed outside the recess.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The LC-type fiber optic connector of this application includes a connector body, a flexible locking arm, and a swing member. The connector body has a thickness direction and a width direction. In the thickness direction, the connector body has a first side. The front part of the flexible locking arm is connected to the first side, and the rear part of the flexible locking arm is suspended. The flexible locking arm is used to engage the fiber optic adapter. The middle part of the swing member is hinged to the first side, and the front end of the swing member abuts against the rear end of the flexible locking arm. The rear end of the swing member has a trigger part, which is arranged on at least one side of the connector body in the width direction. Applying force to the trigger part causes the swing member to rotate. Under the leverage effect of the swing member, the front end of the swing member can push the rear end of the flexible locking arm towards the first side, thereby releasing the flexible locking arm from engaging with the fiber optic adapter. The trigger part is located on one side of the connector body, thus reducing the operating space in the thickness direction required to operate the trigger part. Therefore, the LC-type fiber optic connector of this application is better suited for occasions where the installation space in the thickness direction is limited. Attached Figure Description

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0019] like Figures 1 to 9 As shown, the LC-type fiber optic connector of this application includes a connector body 1, an elastic locking arm 2, and a swing member 3. The connector body 1 has a thickness direction Z and a width direction Y. In the thickness direction Z, the connector body 1 has a first side. The front part of the elastic locking arm 2 is connected to the first side, and the rear part of the elastic locking arm 2 extends rearward while extending away from the first side in the thickness direction Z, thereby making the rear part of the elastic locking arm 2 suspended. The elastic locking arm 2 is used to lock the fiber optic adapter. The middle part of the swing member 3 is hinged to the first side, and the front part of the swing member 3 abuts against the rear part of the elastic locking arm 2. The rear part of the swing member 3 has a trigger part 32, which is arranged on at least one side of the connector body 1 in the width direction Y. The engagement of the elastic locking arm 2 with the fiber optic adapter is achieved by a holding part provided in the middle of the elastic locking arm 2. The elastic locking arm 2 and the connector body 1 are arranged in a clamping manner, and when not subjected to the action of the swing member 3... When the elastic arm 2 is in use, it maintains a large angle with the connector body 1 due to its own elasticity, and the holding part engages with the fiber optic adapter. When it is necessary to remove the connector body 1 from the fiber optic adapter, force is applied to the trigger part 32, which can drive the swinging member 3 to rotate. Under the leverage effect of the swinging member 3, the front part of the swinging member 3 can push the rear part of the elastic arm 2 towards the first side, so that the second end of the elastic arm 2 moves closer to the first side, and the angle between the elastic arm 2 and the connector body 1 is reduced, thereby releasing the elastic arm 2 from the engagement with the fiber optic adapter and unlocking the elastic arm 2. Since the trigger part 32 is located on one side of the connector body 1, the operating space in the thickness direction Z required to operate the trigger part 32 is reduced. Therefore, the LC type fiber optic connector of this application can be better suited for occasions where the installation space in the thickness direction Z is limited.

[0020] In some embodiments of this application, such as Figure 1 , Figure 7As shown, the connector body 1 has a recess 127 on at least one side in the width direction Y, and the trigger portion 32 is disposed outside the recess 127. The recess 127 reduces the space occupied by the connector body 1 and the trigger portion 32 in the width direction Y, thereby reducing the space requirements of the trigger portion 32 on the LC fiber optic connector in the width direction Y. Furthermore, in this embodiment, the trigger portion 32 does not protrude beyond the maximum contour of the connector body 1 in the width direction Y, further reducing the space occupied by the overall structure formed by the connector body 1 and the trigger portion 32 in the width direction Y.

[0021] In some embodiments of this application, the LC-type fiber optic connector further includes a tail sleeve 5. The tail sleeve 5 is slidably fitted onto the outside of the optical fiber, which is connected to the connector body 1. The front part of the tail sleeve 5 is connected to the trigger part 32 via a transmission mechanism. Pulling the tail sleeve 5 backward can cause the swinging member 3 to swing, thereby disengaging the elastic locking arm 2 and the fiber optic adapter. In positions where the fiber optic connectors are closely arranged, it may be difficult to insert fingers into the side gaps to push the trigger part 32. In this case, simply pinching the tail sleeve 5 and pulling it backward can unlock the elastic locking arm 2, making the unlocking operation simpler and improving the insertion and removal efficiency and ease of use of the LC-type fiber optic connector in high-density environments. It should be noted that the tail sleeve 5 is a component also present in existing LC-type fiber optic connectors. In the prior art, the tail sleeve 5 is fixed to the connector body 1 and cannot slide relative to the connector body 1. The difference between the tail sleeve 5 in this application and the prior art is that it is connected to the transmission member 4 and can slide back and forth relative to the connector body 1.

[0022] In some embodiments of this application, such as Figure 1 As shown, the front part of the transmission member 4 is slidably connected to one side of the connector body 1 in the width direction Y. The front part of the transmission member 4 has a stop part 41 that stops the trigger part 32 in the front and back. One of the stop part 41 and the trigger part 32 is provided with a slope 411 that is inclined in the front and back, and the other slides against the slope 411. The rear part of the transmission member 4 protrudes from the connector body 1, and the rear part of the transmission member 4 is connected to the tail sleeve 5. In this embodiment, the trigger part 32 is located behind the stop part 41. The stop part 41 is wedge-shaped with a narrow top and a wide bottom. The slope 411 is provided on the side of the stop part 41 facing the trigger part 32. Pulling the tail sleeve 5 backward can drive the stop part 41 to move backward through the transmission member 4, so that the trigger part 32 slides on the slope 411. At the same time, the force applied by the slope 411 to the trigger part 32 drives the swing member 3 to swing, so that the front part of the swing member 3 presses the rear part of the elastic locking arm 2, thereby unlocking the elastic locking arm 2.

[0023] Furthermore, the trigger part 32 is provided with a forward-protruding protrusion 321 on the side facing the inclined surface 411. The end of the protrusion 321 has a first arc-shaped surface 3211, which slides against the inclined surface 411. The first arc-shaped surface 3211 and the surface of the inclined surface 411 are in line contact, and the contact area is small, which reduces the friction between the inclined surface 411 and the protrusion 321 and ensures that the protrusion 321 slides smoothly on the inclined surface 411.

[0024] In some embodiments of this application, the swing member 3 includes a body portion 31 and a trigger portion 32. The middle portion of the body portion 31 is hinged to the first side via a pivot 6. The front portion of the body portion 31 abuts against the rear portion of the elastic locking arm 2. The rear portion of the body portion 31 extends away from the pivot 6 and towards the first side. The trigger portion 32 is connected to the rear portion of the body portion 31. Specifically, the front portion of the body portion 31 is spaced apart from the connector body 1, and the rear portion of the body portion 31 is arranged at an angle to the front portion of the body portion 31, with the opening of the angle facing the connector body 1. This arrangement reduces the space occupied by the rear portion of the swing member 3 in the thickness direction Z. The trigger portion 32 overlaps with the connector body 1 in the thickness direction Z, making the LC-type fiber optic connector of this application occupy less space in the thickness direction Z.

[0025] In some embodiments of this application, such as Figure 7 As shown, in the thickness direction Z, the rear part of the elastic locking arm 2 has a second arc-shaped surface 21, which abuts against the lower end surface of the body part 31. When the body part 31 pushes against the rear part of the elastic locking arm 2, rolling friction mainly occurs between the second arc-shaped surface 21 and the body part 31, thereby optimizing the mechanical characteristics when unlocking the elastic locking arm 2.

[0026] In some embodiments of this application, there are two trigger parts 32, both of which are connected to the rear of the swing member 3. The two trigger parts 32 are respectively arranged on both sides of the connector body 1 in the width direction Y and slide against the connector body 1. The connector body 1 has mounting grooves 121 extending in the front-rear direction X on both sides in the width direction Y. There are two transmission members 4, the front of one transmission member 4 is slidably disposed in one mounting groove 121, and the front of the other transmission member 4 is slidably disposed in the other mounting groove 121. The front of the tail sleeve 5 is connected to the rear of the two transmission members 4. When unlocking the elastic locking arm 2, pulling the tail sleeve 5 backward can drive the two transmission members 4 to move backward synchronously, so that the two transmission members 4 push the two trigger parts 32 synchronously, making the force on the swing member 3 more balanced in the width direction Y, and ensuring smooth unlocking of the elastic locking arm 2. Among them, the mounting groove 121 not only plays a guiding and limiting role for the transmission member 4, but also plays a role in accommodating the transmission member 4 and preventing the transmission member 4 from protruding outside the connector body 1, thereby increasing the width of the LC type fiber optic connector. In this embodiment, recesses 127 are provided on both sides of the connector body 1 in the width direction Y, and two mounting slots 121 are respectively provided at the corresponding recesses 127.

[0027] In some embodiments of this application, the rear of each of the two transmission members 4 has a limiting portion 43; in the front-rear direction X, the two limiting portions 43 are spaced apart from the connector body 1, forming a limiting space between the two limiting portions 43 and the connector body 1; the tail sleeve 5 includes a tail sleeve body 51 and an outer flange 52 disposed at the front end of the tail sleeve body 51, the outer flange 52 is disposed in the limiting space, and the two limiting portions 43 and the outer flange 52 stop each other front and rear. The tail sleeve 5 is installed through the limiting space, which facilitates the assembly of the tail sleeve 5 and the connector, and reduces the processing cost of the LC type fiber optic connector of this embodiment.

[0028] Furthermore, such as Figure 6 As shown, each of the two limiting parts 43 has a limiting groove 431 on its opposite side in the width direction Y, forming a positioning channel between the two limiting parts 43; the tail sleeve body 51 passes through the positioning channel. The positioning channel extends along the front-rear direction X, and the positioning channel can position the tail sleeve body 51. If the tail sleeve body 51 moves while tilted, it will cause the optical fiber to bend excessively, which may lead to optical fiber failure. In this embodiment, by constraining the outer flange 52 by the limiting space and constraining the tail sleeve body 51 by the positioning channel, the tail sleeve 51 can be prevented from tilting, thereby improving the stability of the optical fiber connection.

[0029] Furthermore, such as Figure 5 , Figures 7 to 9As shown, the transmission component 4 includes a connecting portion 42. The front part of the connecting portion 42 is slidably disposed in the mounting groove 121 and connected to the stop portion 41, while the rear part of the connecting portion 42 is connected to the limiting portion 43. In the width direction Y, guide grooves 521 are provided on both sides of the outer flange 52. One of the two connecting portions 42 is slidably disposed in one guide groove 521, and the other of the two connecting portions 42 is slidably disposed in the other guide groove 521. The provision of two guide grooves 521 allows the guiding and limiting of the tail sleeve 5 to be achieved using only the transmission component 4, without the need for additional guiding components, making the structure of the LC type fiber optic connector in this embodiment more compact.

[0030] In some embodiments of this application, such as Figure 3 , Figure 4 As shown, the connector body 1 includes a shell body 12 and a cover 11. The cover 11 is detachably connected to one side of the shell body 12 in the thickness direction Z. The body portion 31 has a first mounting hole 1111 extending in the width direction Y on the side opposite to the shell body 12. A rotating shaft 6 passes through the first mounting hole 1111. The swing member 3 is hinged to the side of the cover 11 opposite to the shell body 12 via the rotating shaft 6, that is, the side of the cover 11 opposite to the shell body 12 forms part of the first side. The side of the shell body 12 connected to the cover 11 has a stop protrusion 126. When the cover 11 is connected to the shell body 12, the stop protrusion 126 stops the rotating shaft 6 in the width direction Y to prevent the rotating shaft 6 from coming out of the first mounting hole 1111. Specifically, the shell body 12 has an internal receiving space for accommodating optical fibers. The shell body 12 has an opening in the thickness direction Z, and the cover 11 covers the shell body 12 and seals the opening. The cover 11 has two integrally formed first support portions 111 on the side opposite to the shell body 12. The two first support portions 111 are arranged at intervals relative to each other in the width direction Y. Both first support portions 111 are provided with first mounting holes 1111. The swing member 3 has a second support portion 33 integrally formed on the side facing the cover 11. The second support portion 33 is provided with a second mounting hole 331. Before assembling the shell body 12 and the cover 11, the swing member 3 is first connected to the cover 11. When connecting the swing member 3 and the cover 11, the second support portion 33 is first placed between the two first support portions 111. Then, the rotating shaft 6 is inserted into the second mounting hole 331 and the two first mounting holes 1111 to complete the assembly of the swing member 3 and the cover 11. After that, the cover 11 is connected to the shell body 12. The blocking protrusion 126 blocks at least part of both ends of the rotating shaft 6 in the width direction Y, thereby preventing the rotating shaft 6 from detaching from the cover 11. In this embodiment, the stop protrusion 126 can prevent the shaft 6 from detaching, eliminating the need for pins or other components at the end of the shaft 6 to prevent detachment, thus greatly simplifying the assembly process of the LC type fiber optic connector in this embodiment.

[0031] The two mounting slots 121 are respectively provided on both sides of the shell body 12 in the width direction Y; when the cover 11 is connected to the shell body 12, the two trigger parts 32 are respectively arranged on both sides of the shell body 12 in the width direction Y.

[0032] In some embodiments of this application, such as Figures 7 to 9 As shown, the rear sidewall of the shell body 12 has a first slot 122, which extends through the rear sidewall of the shell body 12. The rear sidewall of the shell body 12 facing the cover 11 has a first opening 123, configured to allow the central sleeve 13 to enter the first slot 122 along the thickness direction Z. When the cover 11 is connected to the shell body 12, it can block the first opening 123 to prevent the central sleeve 13 from dislodging from the slot. The tail sleeve 5 is slidably fitted onto the outside of the central sleeve 13. After the cover 11 is connected to the shell body 12, the central sleeve 13 remains fixed to the shell body 12, and the central sleeve 13 serves as a guide and protector for the optical fiber. In this embodiment, the central sleeve 13 can be fixed simultaneously with the connection of the cover 11 to the shell body 12.

[0033] The connector body 1 includes a plug 14, the rear end of which is connected to the front end of the shell body 12. One or more plugs 14 can be provided. In this embodiment, two plugs 14 are provided, spaced apart along the width direction Y. Each plug 14 is connected to an elastic locking arm 2, meaning that one side of each plug 14 in the thickness direction Z also forms part of a first side. The front part of the swing member 3 abuts against the rear part of each elastic locking arm 2. In this embodiment, to facilitate the connection between the cover 11 and the shell body 12, the shell body 12 has a locking hole in its middle, and the cover 11 has a locking protrusion in its middle. The locking protrusion engages with the locking hole, achieving the engagement of the cover 11 and the shell body 12. To facilitate the connection between the plug 14 and the housing body 12, the front sidewall of the housing body 12 is provided with a second slot 124 for securing the plug 14. The front sidewall of the housing body 12 facing the cover 11 has a second opening 125, configured to allow the plug 14 to enter the second slot 124 along the thickness direction Z. When the cover 11 is connected to the housing body 12, it can seal the second opening 125. That is, the cover 11 can simultaneously seal the first slot 122 and the second slot 124, thereby achieving the installation and fixation of the center sleeve 13 and the two plugs 14.

[0034] The assembly method of the LC type fiber optic connector in this application is as follows: First, such as Figure 3 , Figure 5 , Figure 7As shown, the cover 11, the rotating shaft 6, and the swinging component 3 are assembled into the first intermediate assembly 100. The plug 14, the shell body 12, and the center sleeve 13 are assembled into the second intermediate assembly 200. During assembly, the plug 14 and the center sleeve 13 are respectively engaged in the second slot 124 and the first slot 122. The two connectors and the tail sleeve 5 are assembled into the third intermediate assembly 300. During assembly, the connecting parts 42 of the two connectors are respectively placed into the corresponding guide grooves 521.

[0035] After that, as Figure 9 As shown, the third intermediate component 300 and the second intermediate component 200 are assembled into the fourth intermediate component 400. When assembling the third intermediate component 300 and the second intermediate component 200, the connecting portions 42 of the two connectors are inserted into the corresponding mounting slots 121 from back to front.

[0036] Finally, the first intermediate component 100 and the fourth intermediate component 400 are assembled into the LC-type fiber optic connector of this embodiment. During assembly, the cover 11 is engaged with the shell body 12. After the cover 11 and the shell body 12 are engaged, the rear part of the connector body 1 is confined between the two trigger parts 32. Under the blocking action of the two trigger parts 32 on the limiting part 43, the two connectors cannot detach from the connector body 1. The assembly method of the LC-type fiber optic connector of this embodiment is convenient, which greatly reduces the production cost of the LC-type fiber optic connector of this application.

[0037] 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.

[0038] In summary, the LC-type fiber optic connector of this application includes a connector body 1, an elastic locking arm 2, and a swing member 3. The connector body 1 has a thickness direction Z and a width direction Y. In the thickness direction Z, the connector body 1 has a first side. The front part of the elastic locking arm 2 is connected to the first side, and the rear part of the elastic locking arm 2 is suspended. The elastic locking arm 2 is used to lock the fiber optic adapter. The middle part of the swing member 3 is hinged to the first side via a pivot 6. The front part of the swing member 3 abuts against the rear part of the elastic locking arm 2. The rear part of the swing member 3 has a trigger part 32, which is arranged on the connector body. The connector body 1 is located on at least one side in the width direction Y. Force is applied to the trigger part 32, causing the swing member 3 to rotate. Under the leverage effect of the swing member 3, the front part of the swing member 3 pushes the rear part of the elastic locking arm 2 towards the first side, causing the elastic locking arm 2 to disengage from the fiber optic adapter. Since the trigger part 32 is located on one side of the connector body 1, the operating space in the thickness direction Z required for operating the trigger part 32 is reduced. Therefore, the LC-type fiber optic connector of this application is better suited for applications with limited installation space in the thickness direction Z. Furthermore, the LC-type fiber optic connector of this application is easy to assemble and has low processing costs.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
