Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication auxiliary equipment technology, and in particular to a novel quick-plug short-tail jumper. Background Technology
[0002] Patch cords are used to connect fiber optic devices. A patch cord is a connector-equipped cable. In existing patch cords, the optical core is protected by an outer protective sheath. However, during the production and transportation of patch cords, the protective sheath is relatively weak. When the patch cord is subjected to pressure or vibration during transportation, it can easily have a direct impact on the internal optical core, leading to damage or quality problems.
[0003] In addition, because the diameter of the jumper is very small, it is difficult to make it well protected. If the protection is made thicker, the bending ability of the jumper will be greatly reduced. Utility Model Content
[0004] The purpose of this invention is to solve the above-mentioned problems and provide a new type of quick-plug short-tail jumper cable. By setting a stainless steel flexible tube on the core wire, the strength of the core wire is increased, ensuring the strength of the jumper cable during normal transportation and use.
[0005] The technical solution adopted by this utility model is: A novel quick-plug short-tail patch cord is characterized by comprising quick-plug short tails at both ends and a connecting wire in the middle. The connecting wire comprises a core wire formed by two optical cores in the inner layer. The two optical cores extend from the front end of the quick-plug short tails to form two optical fiber heads. The core wires are covered with stainless steel flexible tubes, and a protective sheath is provided on the outer sleeve of the stainless steel flexible tubes. The core wires are laid flat inside the stainless steel flexible tubes.
[0006] Furthermore, the stainless steel flexible hose is formed from a spring made of stainless steel wire.
[0007] Furthermore, a yarn covering layer is provided between the stainless steel hose and the protective skin, and the stainless steel hose, the yarn covering layer and the protective skin form a protective layer outside the optical core.
[0008] Furthermore, the two ends of the yarn covering layer are connected to the core yarn via heat shrink tubing.
[0009] Furthermore, protective sleeves are provided on both optical fiber tips at the front end of the quick-plug short tail.
[0010] The beneficial effects of this utility model are: (1) Stainless steel flexible hoses can withstand impact and pressure, ensuring the safety of the core wire; (2) The yarn covering layer can increase the softness of the jumper and absorb its vibration; (3) The fiber optic head protective sleeve ensures that the optical core is not contaminated when the short tail is quickly plugged in and unplugged.

[0013] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific implementation of a novel quick-plug short-tail jumper of this utility model.
[0014] See appendix Figure 1 , 2 The patch cord of this patent includes quick-plug short tails 1 at both ends and a connecting wire 2 in the middle. The connecting wire 2 includes a core wire 3 formed by two optical cores in the inner layer. The two optical cores extend from the front end of the quick-plug short tails 1 to form two optical fiber heads 4. A stainless steel flexible tube 5 is wrapped around the core wire 3, and the core wire 3 is laid flat inside the stainless steel flexible tube 5. A yarn covering layer 6 is provided outside the stainless steel flexible tube 5. The stainless steel flexible tube 5, the yarn covering layer 6, and the protective sheath 7 protect the optical core.
[0015] Protective sleeves 8 are installed on both optical fiber heads 4 at the front end of the quick-plug short tail 1.
[0016] The stainless steel flexible hose 5 is made by winding stainless steel wire to form a spring-shaped flexible tube. After being covered with a yarn covering layer 6, it is then wrapped with a protective layer. In use, the core wire 3 is inserted into the stainless steel flexible hose 5, and the two ends are connected by heat-shrink tubing 9 and fixed by heat shrinking.
[0017] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
