[0031] The present utility model provides a dual-core optical and electrical composite fiber optic connector 100, which includes a mounting seat assembly 10, two fiber optic connectors 20, a tail sleeve 30, and a push-pull rod 40. Among them, the mounting seat assembly 10 is used to be fixed to an optical and electrical hybrid cable 200; the two fiber optic connectors 20 are installed at one end of the mounting seat assembly 10, and elastic clamping arms 21 are arranged on the same side of the two fiber optic connectors 20; the tail sleeve 30 includes a main body 31 and an elastic snap 32. The main body 31 is sleeved on the mounting seat assembly 10, and the elastic snap 32 is connected to the outer wall surface of the main body 31. One end of the elastic snap 32 extends above the elastic clamping arm 21; the push-pull rod 40 is movably installed in the main body 31 and can move in a direction close to and away from the fiber optic connector 20. When the push-pull rod 40 moves in a direction away from the fiber optic connector 20, the push-pull rod 40 abuts against the elastic snap 32, so that one end of the elastic snap 32 presses against the elastic clamping arm 21, thereby unlocking the elastic clamping arm. When the push-pull rod 40 moves in a direction close to the fiber optic connector 20, the elastic snap 32 and the elastic clamping arm 21 are reset.

[0032] The mounting seat assembly 10 is generally fixed to the cable by heat-shrinking and fixing a protective sleeve 12, so that the protective sleeve 12 shrinks and tightly fits on the surface of the object, with good stability. Of course, a tight-fitting method can also be used. There are various ways to install the fiber optic connector 20 on the mounting seat assembly 10. In some embodiments of the present utility model, the mounting seat assembly 10 includes a seat body 11 and a protective sleeve 12. The seat body 11 is provided with two connector assembly holes 111 and two conductive pins 112. The end portions of the two fiber optic connectors 20 are respectively assembled in the two connector assembly holes 111. On the side of the seat body 11 facing away from the fiber optic connector 20, there is an external thread sleeve 113. A wire routing channel communicating with the connector assembly hole 111 is provided inside the external thread sleeve 113 for the fiber to pass through. The conductive pins 112 are used to connect to the cable 202 in the optical and electrical hybrid cable 200. The protective sleeve 12 is threadedly connected to the external thread sleeve 113. In this way, during assembly, the tail sleeve 30, the protective sleeve 12, and the seat body 11 can be first sleeved on the cable, then the fiber is connected to the fiber optic connector 20, the fiber optic connector 20 is assembled into the connector assembly hole 111, and finally the protective sleeve 12 is screwed tightly outside the external thread sleeve 113. After heat-shrinking and fastening, the tail sleeve 30 is sleeved outside the seat body 11.

[0033] Further, in some embodiments of the present utility model, on opposite sides of the two connector assembly holes 111, the side edges penetrate the outer wall surface of the seat body 11 radially. The inner wall of the connector assembly hole 111 is also provided with a limiting groove. The fiber optic connector 20 is inserted from the side where the connector assembly hole 111 penetrates and cooperates with the limiting groove to limit its own axial movement. Finally, the tail sleeve 30 is sleeved outside the seat body 11, so as to limit the fiber optic connector 20 in the connector assembly hole 111, and the assembly is convenient and fast.

[0034] The above elastic snap 32 is generally integrally formed with the main body 31 using a plastic material, reducing the number of overall components, which is beneficial to improving production efficiency and reducing assembly costs. Moreover, it can ensure the consistency between the elastic snap 32 and the main body 31 and reduce assembly errors. Of course, the elastic snap 32 can also be connected to the main body 31 by means such as snap connection and hot melt fixation. The elastic snap 32 can be deformed under pressure and press against the elastic clamping arm 21, and it can be reset when no external force acts, which is not limited herein.

[0035] There are various specific implementation manners for installing the push-pull rod 40 on the tail sleeve 30. In some embodiments of the present invention, a slide rail is provided on the outer wall surface of the main body 31 of the tail sleeve 30, and the tail sleeve 30 is assembled in the slide rail. In some other embodiments of the present invention, a limiting block 311 protrudes from the outer wall surface of the main body 31. The limiting blocks 311 are arranged at intervals on the side of the elastic snap 32 opposite to the optical fiber connector 20. The push-pull rod 40 is provided with an avoidance hole 41, and the avoidance hole 41 extends in a direction away from the support body 321 and is slidably matched with the limiting block 311. There are many other specific ways to install the push-pull rod 40 on the tail sleeve 30, which will not be listed one by one here.

[0036] There are various ways for the push-pull rod 40 to act on the elastic snap 32 to make it deformed and press against the elastic clamping arm 21. In some embodiments of the present invention, a pressing protrusion is provided on the surface of the elastic snap 32 facing the main body 31. During the pulling process of the push-pull rod 40, the pressing protrusion is pressed against, causing the elastic snap 32 to twist, thereby pressing against the elastic clamping arm 21. After the push-pull rod 40 disengages from the pressing protrusion, the elastic snap 32 resets.

[0037] With the above solution of the present invention, when installing the dual-core optical and electrical composite fiber connector 100 to the interface of the optical connection device, by pushing the push-pull rod 40, when the push-pull rod 40 moves in a direction close to the optical fiber connector 20, the elastic snap 32 and the elastic clamping arm 21 reset. The elastic clamping arm 21 is not restricted by the elastic pressing plate 322 and can be smoothly snap-connected to the interface; when it is necessary to pull out the dual-core optical and electrical composite fiber connector 100 from the interface of the optical connection device, only need to pull the push-pull rod 40, so that the push-pull rod 40 moves in a direction away from the optical fiber connector 20. The push-pull rod 40 presses against the elastic snap 32 to make it deformed and press against the elastic clamping arm 21, and the elastic clamping arm 21 disengages from the snap connection with the interface, then it can be smoothly pulled out, which is convenient and fast.

[0038] Further, in some embodiments of the present utility model, the elastic buckle 32 includes a support body 321 and a pressing plate 322. The support body 321 is connected between the outer wall surface of the main body 31 and the plate surface of the pressing plate 322. The push-pull rod 40 and the elastic clamping arm 21 are respectively located on opposite sides of the support body 321. The pressing plate 322 is inclined towards the main body 31 from the direction away from the elastic clamping arm 21. Such a structure is compact and conducive to realizing the overall miniaturization. When the push-pull rod 40 moves in the direction away from the elastic clamping arm 21, the end of the pressing plate 322 close to the push-pull rod 40 is lifted, and the support body 321 plays a fulcrum role at this time, causing the end of the pressing plate 322 close to the elastic clamping arm 21 to press down, thereby pressing against the elastic clamping arm 21.

[0039] In some embodiments of the present utility model, a top abutting portion protrudes from the surface of the push-pull rod 40 facing the pressing plate 322. When the push-pull rod 40 is pulled, the top abutting portion abuts against the pressing plate 322.

[0040] In some other embodiments of the present utility model, an avoidance hole 41 is formed on the surface of the push-pull rod 40 facing the pressing plate 322, and a bending portion 323 is provided at the end of the pressing plate 322 close to the push-pull rod 40. The bending portion 323 bends into the avoidance hole 41. With such a setting, when the push-pull rod 40 is pulled, the hole wall of the avoidance hole 41 abuts against the bending portion 323, thereby causing the pressing plate 322 to twist. The bending angle of the bending portion 323 is generally not greater than 70 degrees and not less than 30 degrees. On the one hand, it ensures the twisting degree of the pressing plate 322, and on the other hand, it avoids the risk of cracking of the bending portion 323 due to an excessive pressure angle between the bending portion 323 and the hole wall of the avoidance hole 41.

[0041] Further, in some embodiments of the present utility model, the hole wall on the side of the avoidance hole 41 close to the support body 321 is provided with a guiding inclined surface 42. This can increase the smoothness of pulling the push rod during the disassembly and assembly process.

[0042] In some embodiments of the present utility model, a limiting rib 312 protrudes from the outer peripheral edge of the top end of the limiting block 311 to limit the push-pull rod 40 from detaching from the limiting block 311 and improve the structural stability.

[0043] In some embodiments of the present utility model, a plurality of notches 43 are formed at the end of the push-pull rod 40 away from the elastic buckle 32. The plurality of notches 43 are spaced apart in the extending direction of the push-pull rod 40. The plurality of notches 43 can not only relieve stress when the push-pull rod 40 receives a radial force, but also increase the friction between the operator's finger and the push-pull rod 40, further facilitating pushing and pulling.

[0044] Further, in some embodiments of the present invention, the width of the pressing plate 322 at the end away from the optical fiber connector 20 is smaller than the width of the pressing plate 322 at the end close to the optical fiber connector 20. In this way, the shape of the pressing plate 322 matches the overall shape of the dual-core optical and electrical composite fiber connector 100, which is beneficial to reducing the width dimension of the push-pull rod 40 that cooperates with the pressing plate 322.

[0045] In some embodiments of the present invention, the dual-core optical and electrical composite fiber connector 100 further includes two dust caps 50, and the two dust caps 50 are installed at the ends of the two optical fiber connectors 20 to prevent dust, dirt and other particles from contaminating the end faces of the optical fiber connectors 20 and avoid affecting the signal transmission quality of the optical fibers.

[0046] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
