Description

Technical Field

[0001] The utility model relates to the technical field of optical cable connection equipment, in particular to an optical cable connection structure. Background Art

[0002] Optical cable is a commonly used communication equipment. In order to facilitate the rapid connection of optical cables, it is often necessary to use an optical cable device that is easy to connect. The utility model patent with patent application number CN201921971849.8 discloses an optical cable structure that is easy to connect. The first connector and the second connector are arranged to facilitate the rapid connection of two sets of optical cable structure bodies. The structure has a small appearance, convenient operation, a solid structure, and a reliable connection. At the same time, after the first connector and the second connector are connected, the sealing gasket has the characteristics of being waterproof and dustproof. After the jack on the internal connection seat of the first connector is plugged into the pin inside the plug-in slot of the second connector, the threaded groove on the inner side of the locking screw sleeve on the first connector is connected to the second connector. The outer connecting screw threads are rotated and locked, and the threaded connection can ensure long-term and reliable connection, which is convenient for quick connection to form a set of complete optical cables with a long length. The structure is simple and easy to operate. According to the technical solution disclosed, when the existing structure that is easy to connect optical cables is used, on the one hand, after the joints are connected and fixed by threads, the optical cables are easily loosened due to vibration or tension, which is not conducive to ensuring the firmness of the connection of the optical cables. On the other hand, when transmitting optical signals of optical cables, it is often necessary to ensure close contact between the joints. Once the joints are slightly deformed or loosened due to external forces, the optical signals cannot be transmitted smoothly, which is not conducive to ensuring the safe transmission of signals.

[0003] Therefore, how to design a structure that is easy to connect optical cables has become our current problem to be solved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a structure for facilitating the connection of optical cables, so as to solve the problems raised in the above-mentioned background technology. The present invention has a reasonable design, is convenient to use, and is suitable for the quick connection of optical cables.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a structure for facilitating the connection of optical cables, comprising an optical cable and a clamp, a connecting assembly being installed at one end of the optical cable, the connecting assembly comprising a connecting block and a clamping sleeve, a connecting assembly being installed on the inner side of the clamping sleeve, the connecting assembly comprising a guide column and a slot, a clamping assembly being installed on the inner side of the clamping sleeve, the clamping assembly comprising a sleeve and a joint, a rotating assembly being installed on the inner side of the connecting block, the rotating assembly comprising an annular groove and a clamping ring, a rotating assembly being installed on the inner side of the clamping sleeve, the rotating assembly comprising a movable plate and a second magnetic plate, a limiting assembly being installed on the inner side of the clamping sleeve, the limiting assembly comprising a clamping groove and a first magnetic plate.

[0006] Furthermore, the connecting block is fixedly connected to one end of the optical cable, the clamp is fixedly connected to the other end of the optical cable, the slot is opened on the inner side of the clamp, one end of the guide column is installed on the inner side of the slot, and the other end of the guide column passes through the slot and is connected to the other end of the optical cable.

[0007] Furthermore, one end of the plug sleeve is welded to the connecting block, a connection groove is provided on the inner side of one end of the plug sleeve, and the connector is clamped on the inner side of the connection groove.

[0008] Furthermore, one side of the connector is connected to the inner wall of the connection slot via a spring, and one end of the optical cable passes through the connection slot and is connected to the connector.

[0009] Furthermore, one end of the ferrule is clamped on the outer side of the connecting block, the annular groove is arranged on the inner side of the connecting block, the clamping ring is integrally formed on one end of the ferrule, and the clamping ring is clamped on the inner side of the annular groove.

[0010] Furthermore, a slide groove is provided on the top and bottom of the sleeve, one end of the movable plate is stuck in the inner side of the slide groove, the other end of the movable plate passes through the slide groove and extends to the inner side of the sleeve, and the second magnetic plate is welded to the other end of the movable plate.

[0011] Furthermore, the card slots are respectively opened at the top and the bottom of the card head, and the magnetic plate 1 is respectively welded to the two sides of the card slot.

[0012] Furthermore, a metal mesh is installed on the inner side of the optical cable, one end of the metal mesh is sleeved on the outer side of the movable plate, and the other end of the metal mesh is welded to the inner wall of the slot.

[0013] Beneficial effects: 1. When the structure is convenient for connecting optical cables, the sleeve is placed on the outer side of the clamping head, and the flap is pushed upward from the inner side of the sleeve. The flap is used to increase the torque when the sleeve rotates, which is convenient for manual rotation and fixation of the sleeve. The sleeve is screwed on the outer side of the clamping head through threads until the sleeve is fully inserted into the inner side of the slot, and the connecting column is clamped on the inner side of the connector. Then the flap is pushed toward the inner side of the sleeve so that the flap is inserted into the inner side of the slot. At this time, both ends of the magnetic plate 1 and the magnetic plate 2 attract each other. The flap can be used to limit the sleeve to prevent the sleeve from rotating in the opposite direction on the outer side of the clamping head due to vibration or tension, and the magnetic plate 1 and the magnetic plate 2 can be fixed to each other to prevent the flap from moving out of the inner side of the slot, thereby ensuring the limiting effect of the flap.

[0014] 2. After the ferrule and the clamp are connected and fixed, the guide post is clamped on the inner side of the connector, and the connector compresses the spring and moves to the right on the inner side of the connection groove. When there is a slight looseness or deformation between the clamp and the ferrule, the connector and the guide post can still be kept in close contact under the elastic force of the spring, avoiding poor transmission or leakage of the optical signal in the optical cable. At the same time, the metal mesh is used to shield the electromagnetic radiation of the optical cable to ensure the safe transmission of the signal.

When there is a slight looseness or deformation between the clamping head 2 and the ferrule 7, the connector 10 can still be kept in close contact with the guide column 4 under the elastic force of the spring 11, so as to avoid the optical signal in the optical cable from being transmitted poorly or leaking.
