Description

Technical Field

[0001] The utility model relates to the technical field of jumper cables, in particular to a curled optical fiber jumper cable. Background Art

[0002] Fiber optic patch cords are short-distance fiber optic cables used to connect devices in fiber optic communication systems or to connect fiber optic devices. They are usually composed of fiber optic cables with fiber optic connectors at both ends and are used to connect in data centers, between network devices, or between devices and walls. The main features of fiber optic patch cords include: high-speed transmission, low loss, anti-interference, lightweight and safety. Fiber optic patch cords are usually selected based on factors such as connector type, fiber type and length to meet the needs of different network devices and application scenarios.

[0003] Most of the existing optical fiber jumpers do not have a protective structure at the external connector. During transportation and storage, the connector head is very susceptible to external impact, which greatly increases the probability of damage. Therefore, the utility model provides a curled optical fiber jumper to solve the problems raised in the above background technology. Utility Model Content

[0012] Through the above technical solution, the jumper body can be supported by providing support columns.

[0013] Furthermore, the protective cover and the fixed cover are movably sleeved, and a limiting ring is fixedly sleeved on one side of the threaded sleeve;

[0014] Through the above technical solution, the protective cover can be slid into the fixed cover by movably sleeve-arranging the protective cover and the fixed cover, and the movement distance of the threaded sleeve can be limited by setting a limiting ring.

[0015] Furthermore, the base layer is configured as a rubber material, and the shielding layer is configured as a coated shielding material;

[0016] Through the above technical solution, the coated shielding material is usually a composite material containing metal particles or conductive fibers, which can form a continuous shielding film on the surface of the conductor to provide effective shielding protection.

[0035] By setting a fixed cover 202, the reset spring 203 can be protected and the protective cover 204 can be slid into the fixed cover 202 to expose the head of the joint body 201, thereby protecting it during storage or transportation. By setting a threaded sleeve 205 and threadedly sleeved with the protective cover 204, the baffle plate 207 can be moved by rotating the threaded sleeve 205. By setting a torsion spring 206 at the hinge between the connecting rod 208 and the threaded sleeve 205, the baffle plate 207 can always maintain a force to one side so as to block one side of the protective cover 204. When the threaded sleeve 205 moves to one side, the baffle plate 207 is opened due to the restriction of the protective cover 204.

[0036] Both ends of the jumper body 1 are fixedly connected to two connectors 2. The connectors 2 are installed at both ends of the jumper body 1 to connect devices. A support column 102 is provided inside the base layer 103. The jumper body 1 can be supported by providing the support column 102.

Fireproof layer 105 is set to mica tape, which is one of the most commonly used fireproof materials for conductors. It has good fire resistance, can maintain insulation at high temperatures, and prevent flame propagation. Armor layer 106 is set to polyvinyl chloride material, which has good corrosion resistance and mechanical strength, and can provide moderate protection and mechanical support for the jumper.

[0037] Working principle: When the fiber optic jumper is connected, the threaded sleeve 205 at the two connectors 2 is rotated to open the baffle 207. When installing, the connector is inserted into the device, and the protective cover 204 will slide into the fixed cover 202 due to being squeezed, thereby exposing the connector head for connection. When the fiber optic jumper is transported and stored, the protective cover 204 can protect the connector to avoid damage caused by impact.
