Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to an anti-collision optical fiber connector. Background Art

[0002] An optical fiber connector is a device for detachably (actively) connecting between optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output from the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent, and the impact on the system caused by its insertion into the optical link is minimized. This is the basic requirement of the optical fiber connector. To a certain extent, the optical fiber connector affects the reliability and various performances of the optical transmission system.

[0003] However, the existing optical fiber connectors are connected and positioned between the joints by the friction force between the grooves and the protrusions. When they are collided, the two connectors will become loose, resulting in abnormal docking of the optical fibers. Therefore, an anti-collision optical fiber connector is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and an anti-collision optical fiber connector is proposed.

Protective sleeves are provided on the sides of the first connector and the second connector that are away from each other. A slot is provided on one side of the first connector. Two limiting grooves are provided on the top inner wall and the bottom inner wall of the slot. Arc-shaped grooves are provided on the two inner walls of the slot. Positioning holes are provided on the inner walls of the arc-shaped grooves. A plug is fixedly provided on one side of the second connector. The plug is adapted to the slot. Receiving holes are provided on the front and back of the plug. A positioning structure is provided in the receiving holes.

[0006] As a further description of the above technical solution:

[0007] Two limiting strips are fixedly provided on the top and bottom of the plug. The limiting strips are adapted to the limiting grooves.

[0008] As a further description of the above technical solution:

[0009] Protective rings are fixedly provided on the front and back of the first connector. The two protective rings are respectively located outside the two positioning holes.

[0010] As a further description of the above technical solution:

[0011] Two retaining pieces are fixedly provided on the front and back of the plug. Each group of retaining pieces is respectively located on both sides of the two receiving holes. The thickness of the retaining piece is two millimeters.

[0012] As a further description of the above technical solution:

[0017] Anti-slip stickers are fixedly provided on both the top and bottom of the first connector and the second connector, and the anti-slip stickers are made of silica gel.

[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the prior art, for this anti-collision optical fiber connector, by setting the arc-shaped groove, positioning hole, spring, guide plate and push rod, when installing, the second connector is pushed towards the first connector. The plug enters the slot and the arc end of the push rod fits against the inner wall of the arc-shaped groove. When one end of the push rod moves to the position of the positioning hole, the spring pushes the guide plate, and the guide plate then applies a thrust to the push rod, causing one end of it to pop out of the positioning hole, realizing the insertion of the two connectors. The setting of the positioning structure and the positioning hole can strengthen the insertion of the connectors, replacing the traditional friction fixing method. When the device is impacted, it will not become loose, ensuring the normal connection of the optical fiber.

[0020] 2. Compared with the prior art, for this anti-collision optical fiber connector, by setting the limit groove and the limit strip, it can ensure that the first connector and the second connector will not loosen and shake. The setting of the protective ring can block the push rod. When impacted, the acting force will not act on the push rod, thereby preventing the push rod from being accidentally touched and causing the connector to become loose.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Refer to Figures 1 to 3 An anti-collision optical fiber connector provided by the present invention: includes a first connector 1 and a second connector 2. Anti-slip stickers are fixedly provided on the top and bottom of the first connector 1 and the second connector 2. The anti-slip stickers are made of silicone. The setting of the anti-slip stickers can facilitate the insertion and extraction of the first connector 1 and the second connector 2 by the user. Protective sleeves 3 are provided on the sides of the first connector 1 and the second connector 2 away from each other. A slot 4 is provided on one side of the first connector 1. Two limit grooves 5 are provided on the inner walls of the top and bottom of the slot 4. Arc grooves 6 are provided on the inner walls of both sides of the slot 4. Positioning holes 7 are provided on the inner walls of the arc grooves 6. A plug 9 is fixedly provided on one side of the second connector 2. Two flaps 12 are fixedly provided on the front and back of the plug 9. Each group of flaps 12 is located on both sides of two storage holes 11 respectively. The thickness of the flap 12 is two millimeters. The plug 9 and the slot 4 are adapted to each other. Storage holes 11 are provided on the front and back of the plug 9;

[0028] Refer to Figure 2 , in order to achieve the purpose of limiting, two limit strips 10 are fixedly provided on the top and bottom of the plug 9. The limit strips 10 and the limit grooves 5 are adapted to each other. The setting of the limit grooves 5 and the limit strips 10 can limit the connector, ensuring that the first connector and the second connector will not loosen and shake;

[0029] Refer to Figure 1 , in order to achieve the purpose of protecting the thrust rod 133, protective rings 8 are fixedly provided on the front and back of the first connector 1. The two protective rings 8 are respectively located outside the two positioning holes 7. The setting of the protective rings 8 can block the thrust rod 133. When being impacted, the acting force will not act on the thrust rod 133, thereby preventing the thrust rod 133 from being accidentally touched and causing the connector to loosen;

[0030] Refer toFigure 3 To achieve the purpose of strengthening the connector, a positioning structure 13 is provided in the receiving hole 11. The positioning structure 13 includes a spring 131 fixedly connected to the receiving hole 11. One end of the spring 131 is fixedly provided with a guide plate 132. The guide plate 132 is movably connected to the inner wall of the receiving hole 11. A push rod 133 is fixedly provided on the side of the guide plate 132 away from the spring 131. The end of the push rod 133 away from the guide plate 132 is arc-shaped. The arc-shaped end of the push rod 133 is adapted to the arc-shaped groove 6 and the positioning hole 7. The combined use of the positioning structure 13 and the positioning hole 7 can strengthen the insertion of the connector, replacing the traditional friction fixing method. When the device is impacted, it will not become loose, ensuring the normal connection of the optical fiber.

[0031] Working principle: When the first connector 1 and the second connector 2 need to be connected, first, the two push rods 133 are squeezed inward. The push rods 133 squeeze the guide plate 132, and the guide plate 132 then squeezes the spring 131. After the arc end of the push rod 133 retracts into the receiving hole 11, the limiting strip 10 enters the limiting groove 5. Then, the second connector 2 is pushed in the direction close to the first connector 1. The plug 9 enters the slot 4 and the arc end of the push rod 133 fits against the inner wall of the arc-shaped groove 6. When one end of the push rod 133 moves to the position of the positioning hole 7, the spring 131 pushes the guide plate 132, and the guide plate 132 then applies a thrust to the push rod 133, causing one end of it to pop out of the positioning hole 7. The length of the protective ring 8 is greater than the length of the push rod 133 extending out of the positioning hole 7. The setting of the positioning structure 13 and the positioning hole 7 can strengthen the insertion of the connector. When the device is impacted, it will not become loose, ensuring the normal connection of the optical fiber. The setting of the protective ring 8 can block the push rod 133. When impacted, the acting force will not act on the push rod 133, thus preventing the push rod 133 from being accidentally touched and causing the connector to become loose.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
