Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to a fiber optic clip and a fiber optic adapter. Background Technology

[0002] The fiber optic adapter in the optical module is used to fix and couple the external optical fiber to the internal optical fiber. The fiber optic adapter includes a fiber optic clip, a fiber optic plug, a fixing component, and a ferrule. The fiber optic adapter is assembled into the housing of the optical module through the fiber optic clip. The internal optical fiber is installed on the fiber optic plug, which is fixed to the fiber optic clip. The fixing component is used to position and fix the fiber optic plug and the ferrule. The fiber optic clip is used to fix and couple the external optical fiber to the internal optical fiber on the fiber optic plug.

[0003] Existing fiber optic clips, due to their manufacturing or assembly tolerances, have assembly gaps when installed in the housing of optical modules. When the assembly gaps are too large, the fiber optic clips are prone to significant wobbling within the housing of the optical module, causing the external fiber to wobble after being inserted into the clips, resulting in poor coupling and conduction between the external and internal fibers in the optical module. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber optic clip and a fiber optic adapter, enabling the fiber optic clip to be assembled stably and reliably.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Fiber optic clip, including an inner connection portion, the inner connection portion including:

[0007] An inner frame, which surrounds and forms an inner groove, is capable of being inserted into the housing of an optical module along a first direction;

[0008] A locking arm extends along the first direction, and a locking protrusion is provided on the side of the locking arm opposite to the inner groove. When the inner frame is inserted into the housing, the locking protrusion abuts against the inner wall of the housing along the second direction, which is perpendicular to the first direction.

[0009] Preferably, the inner frame has an inner clearance groove at one end facing the inner groove opening, the inner clearance groove extends through the groove wall of the inner groove, the inner groove is connected to the outside through the inner clearance groove, and the locking arm is disposed at the bottom of the inner clearance groove.

[0010] Preferably, there are two inner clearance slots, which are located on opposite sides of the inner connection slot, and each inner clearance slot is provided with a locking arm.

[0011] Preferably, the locking arm has an interference rib on the side facing the inner groove.

[0012] Preferably, the device also includes an outer portion connected to the inner portion, the outer wall of which is provided with a mounting block, the mounting block being configured to be mounted in a mounting groove of the housing.

[0013] The fiber optic adapter includes a fiber optic plug and the aforementioned fiber optic clip, wherein the fiber optic plug is inserted into the inner slot.

[0014] Preferably, the fiber optic plug has a first recessed groove at the end opposite to the fiber optic clip, a second recessed groove at the bottom of the first recessed groove, a plurality of insertion slots arranged side by side on the wall of the second recessed groove, and a plurality of insertion holes arranged side by side at the bottom of the second recessed groove. The insertion slots extend along the first direction, with one end penetrating to the bottom of the first recessed groove and the other end penetrating to the bottom of the second recessed groove, and the plurality of insertion slots and the plurality of insertion holes are aligned one to one.

[0015] Preferably, the fiber optic connector also includes a pin, the fiber optic plug is provided with a connection hole, and the fiber optic clip also includes an external part connected to the inner part. The external part is provided with an external groove at one end opposite to the inner part, and the pin passes through the connection hole with one end extending into the external groove.

[0016] Preferably, the device also includes a fixing member, which is disposed on the side of the fiber optic plug opposite to the fiber optic clip. The fixing member has a locking hole in which the pin is locked.

When the intermediate segment is located in the mounting hole, the wall plate of the fixing member facing the fiber optic plug is sandwiched between the first connecting segment and the second connecting segment.

[0018] The beneficial effects of this invention are:

[0019] The inner frame and locking arm of the fiber optic clip cooperate with each other. The inner frame ensures that the fiber optic clip can be stably inserted into the housing of the optical module along the first direction.

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-10As shown, the present invention provides an optical fiber clip 1, including an inner part 11, which includes an inner frame 111 and a locking arm 112. The inner frame 111 forms an inner groove 1111, which can be inserted into the housing 100 of an optical module along a first direction. The locking arm 112 extends along the first direction, and a locking protrusion 1121 is provided on the side of the locking arm 112 opposite to the inner groove 1111. When the inner frame 111 is inserted into the housing 100, the locking protrusion 1121 abuts against the inner wall of the housing 100 along a second direction, which is perpendicular to the first direction.

[0043] In this invention, the inner frame 111 and the locking arm 112 in the inner part 11 of the fiber optic clip 1 cooperate with each other. The inner frame 111 ensures that the fiber optic clip 1 can be stably inserted into the housing 100 of the optical module along the first direction. After insertion, the locking arm 112 abuts against the inner wall of the housing 100 along the second direction perpendicular to the first direction through the locking protrusion 1121 on it. This prevents the fiber optic clip 1 from shaking when inserted into the housing 100 of the optical module, thus ensuring the reliability and stability of the coupling and transmission between the external and internal optical fibers in the optical module.

[0044] Specifically, an inner clearance groove 1112 is provided at one end of the inner frame 111 facing the opening of the inner groove 1111. The inner clearance groove 1112 extends through the groove wall of the inner groove 1111, and the inner groove 1111 is connected to the outside through the inner clearance groove 1112. The locking arm 112 is disposed at the bottom of the inner clearance groove 1112. The above arrangement makes the overall structure of the inner part 11 more compact and gives the locking arm 112 a larger elastic deformation space.

[0045] More specifically, there are two inner clearance grooves 1112, located on opposite sides of the inner connection groove 1111, and each inner clearance groove 1112 contains a locking arm 112. The two locking arms 112 cooperate to provide a better locking effect, and the fact that the two locking arms 112 are located on opposite sides of the inner connection groove 1111 makes the force more balanced when the inner connection part 11 is inserted into the housing 100.

[0046] In this embodiment, the locking protrusion 1121 is elongated and extends along a third direction. It is located at one end of the locking arm 112 facing the inward clearance groove 1112. The first direction, the second direction and the third direction are perpendicular to each other, which makes the locking more stable and reliable when it is against the ground.

[0047] In another embodiment, the locking arm 112 is provided with an interference rib 1122 on the side facing the inner groove 1111. By providing the interference rib 1122, when the fiber optic plug 2 is inserted into the inner groove 1111, it is subjected to the abutment force of the interference rib 1122, making the insertion more reliable.

[0048] Specifically, the interference rib 1122 can be long and strip-shaped, extending along a third direction.

[0049] Specifically, the fiber optic clip 1 also includes an external portion 12 connected to the inner portion 11. The outer portion 12 is provided with an external slot 1211 at one end opposite to the inner portion 11. The external slot 1211 is configured to accommodate a plug for an external fiber optic cable, thereby enabling the external fiber optic cable to be reliably and stably connected to the internal fiber optic cable.

[0050] More specifically, the external connector 12 includes an external frame 121 and a clamping arm 122. The external frame 121 forms an external slot 1211, and the clamping arm 122 extends along a first direction. When the plug of the external optical fiber is inserted into the external slot 1211, the clamping arm 122 locks it against the side wall of the plug, further ensuring that the external optical fiber is reliably and stably connected to the internal optical fiber.

[0051] More specifically, the outer frame 121 is provided with an outer clearance groove 1212 at one end facing the opening of the outer groove 1211. The outer clearance groove 1212 extends through the groove wall of the outer groove 1211, and the outer groove 1211 is connected to the outside through the outer clearance groove 1212. The clamping arm 122 is provided at the bottom of the outer clearance groove 1212.

[0052] In this embodiment, the inner part 11 and the outer part 12 are integrally formed. Two outer clearance slots 1212 are provided on the outer part 12, located on opposite sides of the outer clearance slot 1211. Each outer clearance slot 1212 contains a clamping arm 122. The two clamping arms 122 cooperate to more reliably clamp and lock the plug of the external optical fiber, and to make the force on the plug of the external optical fiber more balanced.

[0053] Specifically, the outer wall of the external connection part 12 is provided with a mounting block 1213, which is configured to be mounted in the mounting slot of the housing 100. The above configuration enables the fiber optic clip 1 to be reliably installed in the housing 100 of the optical module.

[0054] In this embodiment, the mounting block 1213 is disposed on the outer wall of the outer frame 121, is elongated, and extends along a third direction.

[0055] The present invention also provides an optical fiber adapter, including an optical fiber plug 2 and the aforementioned optical fiber clip 1, wherein the optical fiber plug 2 is inserted into the inner slot 1111.

[0056] In the fiber optic adapter of the present invention, the inner frame 111 and the locking arm 112 in the inner part 11 of the fiber optic clip 1 cooperate with each other. The inner frame 111 ensures that the fiber optic clip 1 can be stably inserted into the housing 100 of the optical module along the first direction. After insertion, the locking arm 112 abuts against the inner wall of the housing 100 along the second direction perpendicular to the first direction through the locking protrusion 1121 on it, so that the fiber optic clip 1 will not shake when inserted into the housing 100 of the optical module, thus ensuring the reliability and stability of the coupling and transmission of the external optical fiber and the internal optical fiber in the optical module.

[0057] Specifically, the fiber optic plug 2 includes an insertion part 21 and a positioning part 22 connected to each other. The insertion part 21 is inserted into the inner slot 1111, and the positioning part 22 abuts against the inner frame 111. The above arrangement makes the insertion and positioning of the fiber optic plug 2 more accurate.

[0058] More specifically, the fiber optic plug 2 has a first recess 23 at the end opposite to the fiber optic clip 1. A second recess 24 is located at the bottom of the first recess 23. Multiple insertion slots 25 are arranged side-by-side on the walls of the second recess 24, and multiple insertion holes 26 are arranged side-by-side at the bottom of the second recess 24. The insertion slots 25 extend along a first direction, with one end penetrating to the bottom of the first recess 23 and the other end penetrating to the bottom of the second recess 24. The multiple insertion slots 25 and the multiple insertion holes 26 are aligned one-to-one. This arrangement allows for more reliable assembly of the internal optical fiber with the fiber optic plug 2.

[0059] More specifically, the fiber optic adapter also includes a ferrule 3, and the fiber optic plug 2 is provided with a connection hole 27. The ferrule 3 passes through the connection hole 27, with one end extending into the external slot 1211. The ferrule 3 can be aligned and inserted into the plug of the external fiber optic cable, so that the external fiber optic cable can be more accurately assembled with the fiber optic adapter.

[0060] In this embodiment, multiple insertion slots 25 are arranged side by side along a third direction, multiple insertion holes 26 are arranged side by side along a third direction, and two insertion pins 3 are provided, extending along a first direction. In the third direction, the multiple insertion holes 26 are located between the two insertion pins 3.

[0061] Specifically, the fiber optic adapter also includes a fixing component 4, which is located on the side of the fiber optic plug 2 opposite to the fiber optic clip 1. The fixing component 4 has a mounting hole 41, in which the pin 3 is mounted. This configuration allows for more precise positioning and fixing of the fiber optic plug 2 and the pin 3.

[0062] More specifically, the fixing member 4 has a frame-shaped structure. The wall plate of the fixing member 4 facing the fiber optic plug 2 is provided with a mounting hole 41 and a channel hole 42 communicating with the mounting hole 41. Along the direction away from the mounting hole 41, the distance between the two side walls of the channel hole 42 gradually increases. The ferrule 3 includes a first connecting section 31, an intermediate section 32, and a second connecting section 33 coaxially connected in sequence. The diameter of the intermediate section 32 is smaller than the diameter of the first connecting section 31 and the diameter of the second connecting section 33. The first connecting section 31 can pass through the channel hole 42, and the intermediate section 32 can move from the channel hole 42 into the mounting hole 41. When the intermediate section 32 is located in the mounting hole 41, the wall plate of the fixing member 4 facing the fiber optic plug 2 is clamped between the first connecting section 31 and the second connecting section 33. The above configuration allows the fixing member 4 to be easily and quickly attached to and detached from the ferrule 3.

[0063] In this embodiment, the length direction of the channel hole 42 is parallel to the second direction. Each pin 3 is configured with a mounting hole 41 and a channel hole 42. When the pin 3 is mounted in the mounting hole 41, the first connecting section 31 is located in the fixing member 4. A wire-passing channel is provided on the fixing member 4 along the first direction. The wire-passing channel is connected to the first recess 23, so that the internal optical fiber can be inserted into the optical fiber plug 2 through the wire-passing channel.
