Description

Technical Field

[0001] This invention relates primarily to the field of communication devices, and more particularly to an optical fiber connector. Background Technology

[0002] Existing fiber optic connectors, especially small LC type connectors, generally use a one-piece molded press-fit type with a spring-loaded locking arm to mate with the adapter. The spring-loaded arm's bending portion primarily relies on material deformation for springback. When using a pull-out structure to unlock the spring-loaded arm, the force required for this is too high due to the deformation of the component, resulting in a difficult connector removal. Alternatively, existing technologies use a tail sleeve to pull down the spring-loaded arm. This structure requires a large force for even small movements, making unlocking difficult and potentially damaging the locking arm or adapter with excessive pull force. Long-term use can lead to decreased connection stability between the connector and adapter. Because of the high pull force, unlocking is difficult, and excessive pull force can damage the locking arm or adapter, leading to connection instability over time. Some solutions require the spring-loaded arm to rotate or utilize other structures to rotate it. However, the rotating structure relies on the deformation of the component itself, making it relatively fragile, especially for plastic parts. Summary of the Invention

The first end of the cam is rotatably disposed on the tail sleeve, and the second end of the cam is disposed on the bottom surface of the tail of the pressure arm.

The cam lifts the tail end of the pressure arm, thereby lowering the front end of the pressure arm. The front end of the pressure arm squeezes the spring arm, thereby reducing the height of the locking structure.

The cam has a first end and a second end. The first end of the cam is rotatably disposed on the tail sleeve, and the second end of the cam is disposed on the bottom surface of the tail of the rocker arm. When the tail sleeve moves axially, the tail sleeve can drive the cam to move and force the cam to rotate, thereby causing the second end of the cam to move away from the main housing in the radial direction. The cam lifts the tail end of the rocker arm, thereby lowering the front end of the rocker arm and reducing the height of the locking structure.

[0013] Preferably, there are at least two connector assemblies; One side wall of the main housing is configured as a detachable structure; When the sidewall of the main housing is removed, the tail of the connector assembly can be inserted and fixed in the radial direction or pulled out and removed from the inner cavity of the main housing, thereby allowing the positions of the connector assemblies to be interchanged.

[0015] Preferably, the elastic component includes a spring and a spring support column; the front end of the spring support column has a column head; The connector assembly has a spring support post through groove at its tail end. The spring support post is slidably disposed in the spring support post through groove. The spring is sleeved on the spring support post, with one end of the spring abutting against the end face of the spring support post through groove and the other end abutting against the rear end face of the post head. The front end of the post head abuts against the sliding slope surface.

[0016] Preferably, the sliding housing is provided with an elastic element storage cavity, which is used to accommodate the spring and the spring support column; the front end of the elastic element storage cavity is connected to the space where the sliding slope is provided, and the spring support column can move back and forth within the elastic element storage cavity.

[0017] Preferably, when the sliding housing is subjected to an external force and slides backward, the baffle is lifted and flipped by the housing of the connector assembly and moves with the sliding housing to the side of the connector assembly.

[0018] Preferably, the portion of the cam at the first end is mounted on the tail sleeve via a pin structure; the edge of the cam at the second end is configured to have an arc shape, the bottom surface of the tail of the swing arm is provided with an arc-shaped surface, and the second end of the cam abuts against the arc-shaped surface.

[0020] The beneficial effects of this invention are as follows: The fiber optic connector provided by this invention uses a cam structure in the tail sleeve to form a lever structure for the pressure arm or swing arm. By sliding the tail sleeve, the tail of the pressure arm or swing arm is raised, thereby pressing down the front end of the pressure arm or swing arm. The front end of the pressure arm squeezes the spring arm or directly lowers the front end of the swing arm, thereby lowering the locking structure on the spring arm or swing arm. This unlocks the connector during the pull-out process. The pull-out unlocking force is low, the cam has low friction and is smooth, and the structure of the pressure arm or swing arm using the rotating shaft has high strength, resulting in smooth unlocking.

[0022] The preferred mechanism and method of motion implementation of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] First of all, it should be noted that the structure of this patent can be applied to single-core connectors as well as dual-core or multi-core connectors. This patent mainly describes dual-core connectors, but those skilled in the art will undoubtedly know that it can also be applied to single-core or multi-core connectors.

[0024] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fiber optic connector includes a main housing 1 with an inner cavity opening towards the front end. The main body of the main housing 1 is primarily composed of four walls, with the top wall having a forward-extending spring arm 101. The root of the spring arm 101 is located on the main body of the main housing 1; optionally, the spring arm 101 can be integrally formed with the main body of the main housing 1. The spring arm 101 has a locking structure 102 for engaging with an adapter. The locking structure 102 is located near the front end and can be a protrusion such as a latch or a bayonet, its specific configuration corresponding to and adapted to the adapter. An auxiliary arm 103 can also be provided at the front of the spring arm 101. The auxiliary arm 103 abuts against the connector assembly 2 or the sliding housing 5 without affecting the sliding movement of the sliding housing 5. Specifically, the auxiliary arm 103 can be configured to be set on both sides of the spring arm 101 and form a grab shape. Its main function is to provide support in front, which can maximize the accuracy of the position of the locking structure 102 in the height direction and assist the spring arm 101 to spring back to the correct position.

[0025] A pin portion 104 is provided on the spring arm 101. The pin portion 104 can be located at the root of the spring arm 101 and the main housing 1 where the spring arm 101 is in a relatively stable position. At the same time, it is necessary to ensure that the pin portion 104 is higher than the top wall of the main housing 1.

[0026] A limiting groove 105 is provided behind the top wall spring arm 101 of the main housing 1. The limiting groove 105 is used to cooperate with the sliding groove 201 of the tail sleeve 2 to limit the extreme position of the sliding groove 201 to prevent the tail sleeve 2 from sliding too far backward and detaching from the main housing 1. A tail extension tube 106 is provided at the tail end of the main housing 1. The tail sleeve 2 is fitted onto the tail extension tube 106, thereby allowing the tail sleeve 2 to move back and forth.

[0027] The bottom main housing 107 of the main housing 1 is detachable from the main body of the main housing 1. The edge of the main housing 1 is provided with a sliding plate 108, which can cooperate with the sliding groove 109 on the inner side of the main body of the main housing 1, so that the bottom main housing 107 can be pulled out from the main body along the axial direction or inserted and fixed to the main body of the main housing 1.

[0028] The front part of the tail sleeve 2 can be fitted onto the tail extension tube 106 of the main housing 1, so that it can move back and forth along the axial direction. The front part of the tail sleeve 2 extends to the outer wall of the top wall of the main housing 1 through the sliding groove 201 and is located at the rear of the spring arm 101. The sliding groove 201 is provided with a receiving groove 202 with the opening facing the top, and the side walls on both sides are provided with pivot holes 203.

[0029] The cam 204 has a first end 205 and a second end 206. The first end 205 of the cam 204 is rotatably disposed in the receiving groove 202 of the tail sleeve 2. The edge of the cam 204 at the second end 206 is configured to have an arc shape.

[0030] The pressure arm 3 is provided with a pin hole 301, which is located in the middle of the pressure arm 3. The position of the pin hole 301 needs to ensure that the front end 302 and the rear end 303 of the pressure arm 3 have sufficient vertical swing distance. The bottom of the rear end 303 of the pressure arm 3 is provided with an arc surface 304. The arc-shaped edge of the cam 204 at its second end 206 abuts against the arc surface 304 at the tail of the pressure arm. The arc surface 304 can abut or cover the arc-shaped edge of the cam 204 at its second end 206 from the rear direction. The pressure arm 3 and the second end of the cam can also be in other ways, such as the pressure arm and the second end of the cam are set together by a rotating shaft.

[0031] There is a certain distance between the first end 205 and the second end 206 of the cam 204. Initially, the straight line containing the first end 205 and the second end 206 is roughly parallel to the axis of the main housing 1. When the tail sleeve 2 is pulled backward, the tail sleeve 2 drives the cam 204 to move backward. Since the second end 206 of the cam abuts on the arc surface 304 of the rear end 303 of the pressure arm 3, the cam 204 will rotate relative to the main housing 1 while moving. The straight line containing the first end 205 and the second end 206 will rotate to an angle with the axis of the main housing 1 that becomes larger and larger, that is, the second end 206 of the cam 204 moves away from the main housing 1. Thus, by pulling the tail sleeve 2, the tail end 303 of the pressure arm 3 is lifted. At this time, the pressure arm 3 swings with the pin 104 as the support point, causing the front end 302 of the pressure arm 3 to press down, squeezing the spring arm 101 to move downward, reducing the height of the locking structure 102, so that the locking structure 102 can disengage from the adapter's snap-fit ​​structure, thereby unlocking the connector from the adapter. To prevent the structure from being too tall, a recessed portion 110 is provided at the junction of the spring arm 101 and the front end 302 of the pressure arm 3, so that the main body of the pressure arm 3 is generally parallel to the top wall of the main housing 1. The pressure arm 3 adopts a rotating shaft structure. The rotating structure itself has no elastic deformation, and the rotational resistance is small, minimizing the risk of breakage of plastic parts or excessive deformation resistance caused by environmental factors, material problems, or weathering at weak points, which could lead to sluggish operation. At the same time, the rear end of the pressure arm 3 is lifted by the cam 204 structure, making the operation smooth and effortless.

[0032] When the pulling force of the tail sleeve 2 is removed, the elasticity of the spring arm 101 and the function of the auxiliary arm 103 can lift the spring arm 101, thereby resetting the position of the locking structure 102.

[0033] Example 2, as Figure 5 , Figure 6 and Figure 7As shown, a fiber optic connector has a main housing 1a with an inner cavity opening towards the front end. The main body of the main housing 1a is mainly composed of four walls. The difference between this embodiment 2 and embodiment 1 is that the top surface of the main housing 1a in embodiment 2 does not have a spring arm, but instead has a swing arm 3a. Top sidewalls 101a extending upwards are provided on both sides of the top surface of the main housing 1a, and pin holes 102a are provided on the top sidewalls 101a. The swing arm 3a is a sheet-like structure with a pin 301a in the middle. A locking structure 302a is provided at the front end of the swing arm 3a, and the bottom of the tail end 303a is used to cooperate with the cam 204 of the tail sleeve 2. The swing arm 3a forms a swingable structure. When the tail sleeve 2 is pulled, the cam 204 of the tail sleeve 2 raises the tail end 303a of the swing arm 3a, thereby lowering the front end of the swing arm 3a and lowering the locking structure 302a. To ensure the swing arm 3a has a rebound force and the locking structure 302a has an upward restoring force, an auxiliary arm 304a is provided at the front end of the swing arm 3a. The auxiliary arm 304a abuts against the connector assembly 4 or the sliding housing 5 without affecting the sliding action of the sliding housing 5. This embodiment mainly replaces the spring arm + pressure arm structure of embodiment 1 with a swing arm structure. The tail sleeve, cam, and detachable bottom housing can be the same as or similar to those in embodiment 1, and will not be described in detail here.

[0034] like Figure 8 and Figure 9 As shown, the tail of connector assembly 4 is located within the inner cavity of the main housing 1, and the front end of connector assembly 4 extends out of the main housing 1 and can communicate with the outside. Specifically, the main body of connector assembly 4 has a square cross-section, and a ceramic ferrule 401 is provided at the front end inside. An optical fiber is fixed inside connector assembly 4, and the front end of the optical fiber is located at the port of the ceramic ferrule 401. The connector communicates with the outside through the ceramic ferrule. The tail of connector assembly 4 is provided with a radially arranged sliding slot 402, and a corresponding slide bar 111 is provided on the side wall of the inner cavity of the main housing 1. During installation, the bottom main housing 107 is pulled forward axially, thus opening the bottom of the main housing 1. Connector assembly 4 is inserted and fixed by aligning the sliding slot 402 with the slide bar 111 from the outside radially, and then the bottom main housing 107 is slidably fastened to the bottom of the main housing 1.

[0035] The sliding slot 402 is provided on both sides of the tail of the connector assembly 4. For dual-core or multi-core connectors, the polarity of the connector can be adjusted by adjusting the position of each connector assembly 4.

[0036] The sliding housing 5 is slidably mounted on the housing of the connector assembly 4, and can slide to at least partially protrude from the front end of the connector assembly 4, and to expose the front end of the connector assembly 4. The sliding housing 5 is a rectangular piece that mates with the connector assembly 4, and is fitted onto the connector assembly 4. A limiting protrusion 403 is provided on the housing of the connector assembly 4, and the limiting protrusion 403 has a forward-facing slope to facilitate the installation of the sliding housing 5. A sliding groove 501 is provided on one side of the sliding housing 5, which cooperates with the limiting protrusion 403 to limit the extreme position of the sliding housing 5, especially the extreme position of the sliding housing 5 sliding forward. A stop 502 is also provided in the middle of the sliding housing 5. When the sliding housing 5 slides backward, the stop 502 can abut against the edge of the front end of the main housing 1, thus limiting the extreme position of the sliding housing 5 sliding backward.

[0037] A baffle 504 that can be flipped inward is also provided on one side of the sliding housing 5. The baffle 504 has an extended edge 505 so that the outer surface of the baffle 504 can be moved to be flush with the outer surface of the sliding housing 5, thereby making the outline neat. The tail of the baffle 504 has a pivot structure 506 with a rotation center. The pivot has a rearward sliding slope 507. When the sliding housing 5 is in the state of extending out of the front end of the connector assembly 4, the baffle 504 flips inward and blocks the front end of the connector assembly 4, especially blocking the ceramic ferrule 401. For this purpose, a groove adapted to the ceramic ferrule 401 can be provided on the inner side of the baffle 504 so that the ceramic ferrule 401 can approach the baffle 504. When the sliding housing 5 slides to expose the front end of the connector assembly 4, the baffle 504 is pushed up by the housing of the connector assembly 4. In order to reduce the collision force between the two, the housing at the front end of the connector assembly 4 can be provided with a slope 405 for colliding with the baffle 504, so as to reduce the collision force and prevent the baffle 504 from rotating too much.

[0038] A spring support column cavity 503 is provided on one side of the sliding housing 5. A spring support column groove 404 is provided at the tail end of the connector assembly 4. The spring support column 508 is slidably disposed in the spring support column groove 404, that is, the tail end of the spring support column 508 can slide back and forth through the spring support column groove 404. A spring 509 is sleeved on the spring support column 508. One end of the spring 509 abuts against the front end face of the spring support column groove 404, and the other end abuts against the rear end face of the column head 510 at the front end of the spring support column 508. The front end of the column head 510 abuts against the sliding slope 507. By pushing the spring support column 508 with the spring 509, the spring support column 508 applies a forward force to the sliding housing 5 through the baffle 504. When not inserted into the adapter, the sliding housing 5 is kept in an extended state, thereby blocking the ceramic ferrule 401 with the baffle 504, keeping the ceramic ferrule 401 clean and preventing light leakage from the ceramic ferrule 401 from causing eye damage to the user.

[0039] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the receiving cavity 503 is connected to the sliding housing 5 at the location where the sliding slope 507 is provided. The front end of the spring support column 508 abuts against the sliding slope 507, and abuts against the surface of the sliding slope 507 located above the rotation center. The column head 510 pushes the sliding slope 507, thereby causing the baffle 504 to have a tendency to rotate into the sliding housing 5. When the sliding housing 5 is pushed backward, especially during insertion into the adapter, the protruding front edge of the sliding housing 5 abuts against the end face edge of the adapter. As the sliding housing 5 slides out of the front end of the connector assembly 4, the baffle 504 is pushed up by the housing of the connector assembly 4. At this time, the head 510 of the spring support column 508 frictionally slides against the sliding slope 507. The head 510 abuts against the sliding slope 507 at a position away from the rotation center of the shaft. The forward thrust of the head 510, through the inclined sliding slope 507, forms a rotational force that causes the baffle 504 to flip inward, thus giving the baffle 504 a tendency to rotate inward into the sliding housing 5. At this time, the distance between the contact point of the head 510 and the sliding slope 507 and the rotation center of the shaft structure 506 is d1, and there is a large angle between it and the sliding housing 5 in the axial direction, thus having a component force that pushes the rotation. The spring support column 508 as a whole will also move backward along with the sliding housing 5. The sliding housing 5 and the connector assembly 4 can be assembled together to form a single component, allowing for polarity reversal when removed from the main housing 1. Finally, the sliding housing 5 slides rearward, while the baffle 504 flips outward and is driven to be substantially parallel to and located on the side of the connector assembly 4.

[0040] As the sliding housing 5 moves forward, especially during the process of the connector being pulled out of the adapter, the forward thrust of the spring 509 acts on the main body of the sliding housing 5 through the baffle 504, causing the sliding housing 5 to move forward. When the sliding housing 5 moves forward and the baffle 504 disengages from the housing of the connector assembly 4, the sliding ramp 507 generates a thrust that pushes the baffle 504 to rotate inward. During the rotation, the head 510 at the front end of the spring support column 508 slides close to the rotation center of the rotating shaft structure 506. At this time, the distance between the contact point of the head 510 and the sliding ramp 507 and the rotation center of the rotating shaft structure 506 is d2. The head 510 moves forward a small distance relative to the elastic element receiving cavity 503, causing the baffle 504 to flip by the forward thrust. This flipping force is small but sufficient to stabilize the baffle 504 at the front end of the ceramic ferrule 401.

[0041] The auxiliary arm 103 at the front end of the spring arm 101 abuts against the sliding housing 5. The auxiliary arm 103 is a small claw-shaped abutting against the edge of the sliding housing 5, which does not affect the forward and backward movement of the sliding housing 5. At the same time, as the sliding housing 5 moves backward, the baffle 504 will be raised first and its surface will be flush with the surface of the sliding housing. Then the auxiliary arm 103 slides across the surfaces of the baffle 504 and the sliding housing 5.
