Description

Technical Field

[0001] The invention relates to the technical field of optical connectors, in particular to an optical connector component which is convenient for plugging and connecting. Background Art

[0002] A fiber optic connector is a device that provides a detachable and movable connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of a fiber optic connector. To a certain extent, the fiber optic connector affects the reliability and performance of the optical transmission system.

[0003] For example, the invention with publication number CN105899818B discloses a lockable connector and a connection assembly. The connector of the invention includes a coupling nut with a finger-shaped flange, which is arranged at one end of the coupling nut and is configured to engage a non-rotatable connector body when connected to an adapter to prevent unintentional movement of the coupling nut. However, in actual use of such devices, after the plug and socket of the connector are aligned and plugged, the nut needs to be additionally rotated to perform the locking operation, resulting in a relatively general problem of overall convenience of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an optical connector assembly with convenient plugging is proposed. Summary of the invention

The bracket is fixedly connected to the plug, and the end of the bracket is provided with an avoidance groove.

[0010] Furthermore, a shielding assembly is provided at the end of the socket, and the shielding assembly includes a support plate, a limiting rod and a sliding seat. Support plates are fixed at both ends of one side of the mounting plate, and the end of the support plate is connected to the limiting rod, and the outer side of the limiting rod is slidably connected to the sliding seat.

[0011] Furthermore, the shielding assembly also includes a positioning spring, a baffle and a driving block. A positioning spring is provided on one side of the slide seat, a baffle is fixed to the end of the slide seat, and a driving block is provided on one side of the baffle.

[0012] Furthermore, the driving block is trapezoidal, and the length of the driving block is consistent with the length of the baffle.

[0013] Furthermore, a first cleaning strip is arranged outside the end of the socket, and the first cleaning strip is fitted with the baffle, a partition is fixed outside the middle of the socket, and second cleaning strips are arranged on the upper and lower sides of the partition.

[0016] The present invention provides an optical connector assembly that is easy to plug and play, and has the following beneficial effects:

[0017] 1. In the process of plugging, the present invention can guide the plug and the socket by using the slider and the slide groove to avoid rotational dislocation during the docking process. At the same time, the fixing rod will pass through the avoidance groove and contact the inclined surface on the guide groove, so that the limit sleeve will rotate under the guidance of the inclined surface. When the limit column moves to the inside of the limit groove, the torsion spring will drive the limit sleeve to reset under the limit of the fixing ring, so that the limit column is engaged in the limit groove. Therefore, during the plugging operation, the socket and the plug can be locked without additional operation, thereby improving the convenience of plugging. When pulling out and separating, it is only necessary to rotate the limit sleeve in advance and then pull the plug to quickly separate and disassemble it.

[0018] 2. The present invention can pick up the plug by pinching the anti-slip plates on the upper and lower sides. At this time, as the distance between the anti-slip plate and the plug is shortened, the connecting rod will be driven to move through the rotating plate. At the same time, the fixed sleeve will improve the stability of the connecting rod when it moves, so that it can pull the driving plate through the sliding column to make the protective plate rotate a quarter of a turn at the end of the bracket. The protective plate will not block the end of the plug to facilitate the plug-in operation. When not in use, the spring seat can push the rotating plate to move it up and reset. Similarly, the protective plate can shield and protect the end of the plug to prevent dust from entering and causing pollution.

[0019] 3. In the process of plugging, when the plug contacts the driving block, the contact surface is inclined, so the driving block is pushed, causing the baffle to move to both sides. At this time, the limit rod and the slide seat can limit and guide the direction of the baffle movement, so that during the plugging process, the socket port is automatically unblocked. When the plug is separated from the socket, the positioning spring pushes the slide seat, causing the baffles at both ends to move toward the center, so that the port of the socket can be automatically closed, further improving the overall protection performance.

[0020] 4. After the present invention is plugged in, the protective plate and the baffle will be exposed to the outside, and some dust and impurities may adhere to them, causing the inner side to carry dust and impurities into the interior of the socket and the plug after closing. At this time, through the setting of the first cleaning strip and the second cleaning strip, when the baffle is moved back and reset, it will contact the first cleaning strip to automatically clean the baffle. At the same time, when the protective plate is moved back and reset, it can also contact the second cleaning strip to automatically clean it, thereby improving the overall dustproof effect. When plugging in, the protective plate will also squeeze the guide block to move the protective cover up, and when separated, the counterweight block will drive the protective cover to move down to cover the top of the second cleaning strip to prevent dust from settling on its top and affecting the subsequent use effect.

[0031] The specific operation is as follows: first, pinch the anti-slide plates 402 on the upper and lower sides to pick up the plug 3. At this time, as the distance between the anti-slide plate 402 and the plug 3 is shortened, the connecting rod 404 will be driven to move through the rotating plate 403. At the same time, the fixing sleeve 405 will improve the stability of the connecting rod 404 when it moves, so that it can pull the driving plate 407 through the sliding column 406, so that the protective plate 408 can rotate a quarter of a circle at the end of the bracket 409, and the protective plate 408 will not block the end of the plug 3, so as to facilitate the plugging operation. During the plugging operation, the slider 501 and the slide groove 504 will guide the plug 3 and the socket 1 to avoid rotational dislocation during the docking process. At the same time, the fixing rod 502 will pass through the avoidance groove 410 and contact the inclined surface on the guide groove 506, thereby guiding the inclined surface. The limit sleeve 505 rotates downward, and when the limit column 503 moves to the inside of the limit groove 507, the torsion spring 508 will drive the limit sleeve 505 to reset under the limit of the fixing ring 509, so that the limit column 503 is engaged in the limit groove 507. Therefore, during the plugging operation, the socket 1 and the plug 3 can be locked without additional operation, thereby improving the convenience of plugging. When the socket 1 and the plug 3 need to be separated, it is only necessary to rotate the limit sleeve 505 in advance, and then pinch and pull the anti-slip plate 402 to quickly separate and disassemble them. After letting go, the spring seat 401 can push the rotating plate 403 to move it up and reset. Similarly, the protective plate 408 can be used to shield and protect the end of the plug 3 to prevent dust from entering and causing pollution.

[0033] The specific operation is as follows: when the plug 3 contacts the driving block 606, due to the inclined contact surface, the driving block 606 is pushed to drive the baffle 605 to move to both sides. At this time, the limit rod 602 and the slide seat 603 can limit and guide the direction of the baffle 605 when it moves, so that during the plugging process, the shielding of the port of the socket 1 is automatically released. At the same time, the protective plate 408 will squeeze the guide block 1004, so that the protective cover 1003 moves up, and the upper protective plate 408 will be located between the protective cover 1003 and the second cleaning strip 9.

Secondly, during the plug-in operation, when the plug 3 contacts the driving block 606, the contact surface is inclined, so it will The driving block 606 is pushed to drive the baffle 605 to move to both sides. At this time, the direction of the movement of the baffle 605 can be limited and guided by the limiting rod 602 and the sliding seat 603, so that during the plugging process, the shielding of the port of the socket 1 is automatically released.

Therefore, after plugging, the socket 1 and the plug 3 can be automatically locked. Then, when the socket 1 and the plug 3 need to be separated, it is only necessary to rotate the limiting sleeve 505 in advance, and then pinch and pull the anti-slip plate 402 to quickly separate and disassemble them. In this process, the protective plate 408 will contact and slide with the second cleaning strip 9 for automatic cleaning, and when separated, the counterweight block 1005 will drive the anti-slip plate 408 to slide. The shield 1003 moves downward under the guidance of the vertical rod 1002 and the limit frame 1001 to cover the top of the second cleaning strip 9 to prevent dust from settling on the top and affecting the subsequent use effect.
