[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1-5 To further explain this application,

[0024] The embodiment of the present application discloses an optical passive component connector with an anti-drop structure. Figure 1-5 A passive optical component connector with an anti-drop structure includes a connector body 1, which includes a male connector 101, a female connector 104 is provided on the right side of the male connector 101, a protective shell 102 is fixedly connected to the right side of the male connector 101, and a hole block 103 is fixedly connected to the left side of the female connector 104. The hole block 103 is snapped into the inner cavity of the protective shell 102, and a plug post 105 is installed on the right side of the male connector 101. The plug post 105 is snapped into the inner cavity of the hole block 103. The top and bottom of the male connector 101 are both installed with a snap mechanism 2;

[0025] The snap mechanism 2 includes a protective sleeve 201, which is fixedly connected to the surface of the male head 101. The top and bottom of the protective sleeve 201 are fixedly connected to positioning plates 202. There are four positioning plates 202. The inner cavity of the positioning plate 202 is fixedly connected to a rotating shaft 203. The surface of the positioning plate 202 is rotatably connected to a rotating plate 205. A telescopic mechanism 3 is provided inside the rotating plate 205. The other end of the rotating plate 205 is movably connected to an adjusting rod 207, and the other end of the adjusting rod 207 is fixedly connected to a blocking block 209.

[0026] Reference Figure 3 The front and back sides of the rotating plate 205 are fixedly connected to a torsion spring 204, and the other end of the torsion spring 204 is fixedly connected to one side of the positioning plate 202. The torsion spring 204 is sleeved on the surface of the rotating shaft 203. Through the setting of the rotating shaft 203, the rotating plate 205 can be rotated on the surface of the rotating shaft 203. The setting of the torsion spring 204 can limit the position of the rotating plate 205. When the rotating plate 205 rotates, it can automatically rebound to its initial state.

[0027] Reference Figure 5 The telescopic mechanism 3 includes a first slide groove 301, which is opened in the inner cavity of the rotating plate 205. The slider 304 is slidably connected to the interior of the first slide groove 301. The right side of the slider 304 is fixedly connected to the left side of the adjusting rod 207. The front and back sides of the slider 304 are fixedly connected to the sliding column 305. The front and back sides of the inner cavity of the first slide groove 301 are both provided with a second slide groove 302. The sliding column 305 is slidably connected to the interior of the second slide groove 302. Through the setting of the first slide groove 301, the slider 304 can be moved therein, and through the setting of the second slide groove 302, the sliding column 305 can be moved therein, thereby guiding the slider 304.

[0028] Reference Figure 5 A tension spring 303 is fixedly connected to the left side of the inner wall of the first slide groove 301, and the other end of the tension spring 303 is fixedly connected to the left side of the slider 304. Due to the setting of the tension spring 303, when the adjusting rod 207 is extended or retracted, it is deformed. When the adjusting rod 207 loses its force, the adjusting rod 207 is retracted into the inside of the rotating plate 205;

[0029] Reference Figure 4 and Figure 5 The right side of the rotating plate 205 is fixedly connected to a limit block 206, and the diameter of the limit block 206 is smaller than the diameter of the first slide groove 301. The adjusting rod 207 is movably connected to the inner cavity of the limit block 206. The setting of the limit block 206 effectively limits the slider 304, thereby preventing the slider 304 from being accidentally pulled out of the inner cavity of the first slide groove 301 when pulling the finger buckle 208, causing unnecessary damage;

[0030] Reference Figure 4 and Figure 5 The top of the adjusting rod 207 is fixedly connected with a finger buckle 208, which is in the shape of a semi-ring. The setting of the finger buckle 208 effectively increases the force application point, so that when the operator needs to pull the adjusting rod 207, it can be more labor-saving and easy.

[0031] Reference Figure 1 and Figure 2 The right side of the female head 104 is fixedly connected with a threaded ring 4, and the surface of the threaded ring 4 is threadedly connected with a screw sleeve 5. The surface of the screw sleeve 5 is provided with a strip groove. The right side of the screw sleeve 5 is in close contact with the left side of the block 209. Through the setting of the threaded ring 4, the screw sleeve 5 can be moved on its surface. Through the setting of the screw sleeve 5, it is in close contact with the block 209 after movement, thereby improving the tightness of the connection of other structures.

[0032] Working principle: After docking the female head 104 with the male head 101, first lift the finger buckle 208 upwards by hand to drive the rotating plate 205 to rotate. The rotation of the rotating plate 205 drives the torsion spring 204 to rotate. Then pull the finger buckle 208 backward by hand to drive the adjusting rod 207 and the block 209 to move. The slider 304 and the sliding column 305 are driven to move by the adjusting rod 207. When the slider 304 moves, it drives the tension spring 303 to move. At this time, press the finger buckle 208 down to clamp the block 209 to the right side of the female head 104 to achieve a fixing effect. Then rotate the screw sleeve 5 to move the screw sleeve 5 to the left so that the screw sleeve 5 contacts the block 209. At this time, continue to move the screw sleeve 5 to further fix the male head 101 and the female head 104, making the two more firm and achieving an anti-falling effect.
