Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber jumpers, in particular to a joint protection structure. Background Art

[0002] Fiber optic patch cords are a type of cable assembly used to connect fiber optic devices. They have the advantages of high-speed transmission, low loss, strong anti-interference, and good flexibility. Common types of fiber optic patch cords include single-mode fiber optic patch cords and multi-mode fiber optic patch cords, which differ in transmission distance, applicable scenarios, etc. When selecting a fiber optic patch cord, factors such as transmission distance, transmission rate, and connector type need to be considered to ensure that it can meet specific application requirements.

[0003] When existing fiber optic patch cords are not in use, their connectors are exposed, so they are very likely to be damaged structurally due to collisions, scratches, etc., affecting the stability and reliability of the connection. Therefore, the connectors need to be protected. Without a protective structure, dust may enter the connectors and gradually accumulate, causing signal attenuation; or the connectors may be accidentally hit during the process of transporting equipment, which may cause them to be damaged and unable to be used normally. Some connectors with protective structures are only provided with a single protective structure, and there is no mechanism to limit the protective structure. Therefore, the protective cover is very likely to be pulled and slip. To address this problem, we have proposed a connector protection structure. Utility Model Content

The L-shaped rod fixed on the surface of the pressure plate is forced to retract into the cylinder under the support of the spring. The L-shaped rod moves out from the horizontal hole opened on the surface of the support frame. When it moves into the circular hole, the cylinder is moved, and the L-shaped rod can rotate in the circular hole. The circular rod fixed on the surface of the cylinder can drive the cylinder to rotate on the surface of the connecting seat. When the L-shaped rod is located in the horizontal hole, the cylinder cannot rotate, and the protective sleeve cannot be separated from the joint.

This method can stably protect the joint and prevent the exposed joint from being contacted by dust or damaged by impact. BRIEF DESCRIPTION OF THE DRAWINGS

Pressing the two sets of pressing plates 773, the L-shaped rod 771 fixed on the surface of the pressing plate 773 is forced to be retracted into the cylinder 76 under the support of the spring 772. The L-shaped rod 771 is When 71 is moved out of the transverse hole 74 opened on the surface of the support frame 73 and moved into the circular hole 75, the cylinder 76 is moved, and the L-shaped rod 771 can rotate in the circular hole 75, and the circular rod 81 fixed on the surface of the cylinder 76 can drive the cylinder 82 to rotate on the surface of the connecting seat 2. When the L-shaped rod 771 is located in the transverse hole 74, the cylinder 76 cannot rotate, and the protective sleeve 5 cannot be separated from the joint 3. This method can stably protect the joint 3 and avoid loosening due to pulling, thereby achieving the purpose of stably protecting the joint 3.

[0027] A through hole 4 is provided on the surface of the connecting seat 2, and the provision of the through hole 4 can limit the movement of the protective sleeve 5. The limiting member 77 includes: an L-shaped rod 771, the L-shaped rod 771 passes through the cylinder 76 and is slidably connected to the cylinder 76, the inner wall of the cylinder 76 is fixedly connected to one end of a spring 772, and the other end of the spring 772 is fixedly mounted on the surface of the L-shaped rod 771, the L-shaped rod 771 passes through the support frame 73, and when the L-shaped rod 771 is subjected to force, it can slide into the cylinder 76 under the support of the spring 772.
