Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a connector socket with dustproof function. Background Technology

[0002] One problem with fiber optic connectors on the market is their open plug design, which makes the optical conductors highly susceptible to contamination, especially dust. Some products add a rubber plug, but when in use, the open rubber plug easily attracts dust, posing a possibility of secondary contamination. Moreover, it is easy to forget to plug the rubber plug when not in use. It is essential to provide necessary protection for the connector plug of fiber optic connectors to prevent dust / contaminants from entering. Furthermore, it is necessary to achieve active dust prevention, automatically opening when in use and automatically closing when not in use.

[0003] A patent application (CN202510169066.1) discloses a plug, socket, and connector with dustproof functionality. The plug's front end is equipped with a first dustproof component. This first dustproof component includes: a dustproof front cover, with a front portion as the face and a rear portion as the insertion portion; an insertion hole in the center of the dustproof front cover; two dustproof baffles, arranged left and right, respectively pivotally connected to the inner wall of the insertion portion of the dustproof front cover's insertion hole, each baffle having a connecting push arm with a pushing post; a dustproof rear cover, with a through hole in the center to allow the dustproof baffle to open and close, thus covering or blocking the insertion hole; and at least one elastic element supported between the dustproof front and rear covers. This invention also discloses a corresponding socket and its connector. It employs a double-door, double-spring reset design, resulting in higher structural reliability and better dustproof performance, but the structure is complex. A simpler structure could achieve the same functionality. Utility Model Content

[0004] This utility model addresses the problems of existing technology by proposing a connector socket with a dustproof function. The dustproof function is achieved by rotating the dustproof rotating plate, and the dustproof rotating plate is opened by the movable shell. It not only has a simple structure, but also has a good dustproof effect.

[0005] The technical solution of this utility model is: a connector socket with dustproof function, capable of optical and / or electrical conduction when plugged into a mating plug in at least one insertion direction, comprising a socket housing, a socket core fixed inside the socket housing, and the socket housing and socket core having their respective insertion ports in the insertion direction, wherein a dustproof component is provided at the front end of the socket; characterized in that the dustproof component includes:

[0006] A movable outer shell is arranged back and forth in the slot formed by the gap between the socket outer shell and the socket core;

[0007] A dustproof rotating plate is rotatably fixed to the outer wall of the socket core. It has a connecting part and a baffle that are connected to each other. The baffle can cover the insertion port of the socket core by rotating along the connecting part.

[0008] A mounting slot is arranged on the outer wall of the socket core to install the connecting part of the dustproof rotating plate. After the connecting part of the dustproof rotating plate is pushed by the movable shell, the connecting part can drive the dustproof rotating plate to rotate.

[0009] A reset torsion spring is installed on the connection part to ensure that the dustproof rotating plate always tends to cover the insertion port of the socket core.

[0010] A return spring, at least one set, is disposed between the movable housing and the socket core, always maintaining the tendency of the movable housing to push outward.

[0011] Furthermore, the connecting part includes at least a pair of lugs, a rotating shaft is fixed inside the lugs, the rotating shaft is rotatably fixed in the mounting slot, a transition slope is provided between the dustproof rotating plate and the rotating shaft, and a reset torsion spring is sleeved on the rotating shaft, which always applies an outward rotational force to the dustproof rotating plate.

[0012] Furthermore, the movable outer shell has an inwardly extending annular inner wall at the front opening as an active pressing part. The active pressing part drives the baffle to rotate by contacting the transition slope on the dustproof rotating plate.

[0013] Furthermore, a fixing groove is provided on the outer wall of the socket core, and a reset spring is arranged on the fixing groove. The other end of the reset spring abuts against the guide block on the inner wall of the movable outer shell, and the reset spring always applies an outward force to help the movable outer shell reset.

[0014] Furthermore, the insertion port is smaller than the dustproof rotating plate, and the inner wall of the movable outer shell serves as a limiting part to prevent the dustproof rotating plate from excessively resetting.

[0015] Furthermore, the bottom of the socket core is provided with a positioning pin, which matches the positioning hole of the plug to realize the positioning insertion function.

[0016] Furthermore, the inner wall of the socket housing is provided with a ring of waterproof grooves, and a waterproof ring is arranged on the waterproof grooves to prevent sewage from entering.

[0017] Finally: Guide limiting blocks are distributed on the left and right sides of the socket core, and correspondingly, guide limiting holes are opened on the left and right sides of the movable outer shell.

[0018] Compared with the prior art, the advantages of this utility model are as follows: the movable outer shell drives the dustproof rotating plate to rotate, making it convenient for the plug to be inserted into the socket. When the plug is pulled out, the reset torsion spring on the rotating shaft drives the dustproof rotating plate to cover the insertion port, and the movable outer shell will also be reset by the reset spring. It is very convenient to use. Moreover, with the guide limit structure, the operation is stable and reliable, not easy to be damaged, the structure is simple, and the dustproof effect is good.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] according to Figures 1 to 6 A dustproof connector socket, capable of optical and / or electrical conduction when plugged into a mating plug in at least one insertion direction, includes a socket housing 1, a socket core 2 fixed inside the socket housing 1, and insertion ports 3 and 3a respectively on the socket housing 1 and socket core 2 in the insertion direction. A dustproof component 4 is provided at the front end of the socket. The improvement lies in that the dustproof component 4 includes: a movable housing 5 arranged back-and-forth in an annular slot 23 formed by the gap between the socket housing 1 and the socket core 2; and a dustproof rotating plate 6 rotatably fixed to the outer wall of the socket core 2. The device has a connecting part 7 and a baffle 8 that are interconnected. The baffle 8 can rotate along the connecting part 7 to cover the insertion port 3a of the socket core 2. The mounting slot 9 is arranged on the outer wall of the socket core 2. The connecting part 7 for mounting the dustproof rotating plate 6 is arranged so that after the connecting part 7 of the dustproof rotating plate 6 is pushed by the movable housing 5, the connecting part 7 can drive the dustproof rotating plate 6 to rotate. The reset torsion spring 10 is provided on the connecting part 7 so that the dustproof rotating plate 6 always maintains the tendency to cover the insertion port 3a of the socket core 2. At least one set of reset springs 11 is provided between the movable housing 5 and the socket core 2 so as to always maintain the tendency of the movable housing 5 to push outward.

[0031] The more specific structure is as follows: the connecting part 7 includes at least a pair of lugs 12, and a rotating shaft 13 is fixed inside the lugs 12. The rotating shaft 13 is rotatably fixed in the mounting slot 9. A transition slope 14 is provided between the dustproof rotating plate 6 and the rotating shaft 13. A return torsion spring 10 is sleeved on the rotating shaft 13, which always applies an outward rotational force to the dustproof rotating plate 6, so that the dustproof rotating plate 6 and the movable outer shell 5 abut against each other, thereby covering the insertion port 3 of the socket core 2 and preventing dust and other dirt from entering. The movable outer shell 5 has an inwardly extending annular inner wall at the front opening, which serves as an active pressing part 15. When the movable outer shell 5 moves backward, the active pressing part 15 abuts against the transition slope 14 on the dustproof rotating plate 6, thereby driving the baffle 8 to rotate and opening the insertion port 3 of the socket core 2. The insertion port 3 of the socket core 2 is slightly smaller than the dustproof rotating plate 6. The inner wall of the movable outer shell 5 acts as a limiting part to prevent the dustproof rotating plate 6 from over-resetting. The dustproof rotating plate 6 usually rotates at most 90° along the pivot 13 before contacting the inner wall of the movable outer shell 5. The outer wall of the socket core 2 has a fixing groove 16, usually two grooves arranged vertically. A return spring 11 is arranged on the fixing groove 16, and the other end of the return spring 11 abuts against a guide block 17 on the inner wall of the movable outer shell 5. The return spring 11 always applies an outward force and helps the movable outer shell 5 to automatically reset. Guide limiting blocks 21 are distributed on the left and right sides of the socket core 2. Correspondingly, guide limiting holes 22 are opened on the left and right sides of the movable outer shell 5, allowing the movable outer shell 5 to slide within a set distance range while fitted over the socket core 2. The bottom of the socket core 2 has a positioning pin 18, which matches the positioning hole of the plug to prevent incorrect insertion and to achieve a limiting insertion function. Waterproof grooves 20 are distributed in a ring on the inner wall of the socket housing 1, and waterproof rings 19 are arranged on the waterproof grooves 20 to prevent sewage from entering.

[0032] When using this product, the user only needs to align the plug with the insertion port 3 at the front of the socket. The plug core passes through the insertion port 3 inside the movable housing 5. At this time, the plug housing will abut against the surface of the movable housing 5, causing the movable housing 5 to move backward. The active pressing part 15 on the inner wall of the movable housing 5 will then abut against the transition slope 14 on the dustproof rotating plate 6, thereby causing the dustproof rotating plate 6 to rotate inward along the rotating shaft 13. This stops the dustproof rotating plate 6 from blocking the insertion port 3a of the socket core 2, allowing the plug core to be inserted into the socket core 2, thus achieving optical or electrical signal connection. The positioning pin 18 at the bottom of the socket core 2 matches the positioning hole of the plug core to ensure that the user can correctly plug in and fix it. When the movable outer shell 5 moves backward, the return spring 11 compresses its stroke to move the movable outer shell 5 forward. When the user pulls the plug out of the socket, the return spring 11 will pop the movable outer shell 5 outward until the limit position. When the movable outer shell 5 moves outward and resets, the dustproof rotating plate 6 will also rotate and reset according to the force applied by the reset torsion spring 10 on the rotating shaft 13, so that the baffle 8 can cover the insertion port 3a of the socket core 2 again to achieve the dustproof function.
