Description

Technical Field

[0001] This utility model relates to the field of jumper wire technology, specifically a bending-resistant MT short jumper wire. Background Technology

[0002] A jumper is essentially a metal wire connecting two points on a circuit board (PCB). Due to different product designs, the materials and thickness of jumpers vary. Most jumpers are used for transmitting voltage at the same potential, while some are used for reference voltage in protection circuits. For applications requiring precise voltage, even a small voltage drop from a metal jumper can significantly impact product performance. MT jumpers are a type of fiber optic jumper, and their use requires bending at the middle.

[0003] The prior art includes an optical fiber patch cord, an optical fiber patch cord testing tool, and a testing method, with application number 202011281442.X. The proposed optical fiber patch cord extends the optical fiber coupling point formed by the plastic optical fiber from the reinforcement section. It is equipped with a dedicated optical fiber patch cord testing tool and method. The testing process does not require disconnecting the running optical fiber link, ensuring uninterrupted signal transmission of the optical fiber patch cord. It can intuitively and efficiently complete the target optical fiber patch cord location work, greatly improving the efficiency of on-site operation and maintenance. However, the MT patch cord has poor bending resistance in the middle and is easily damaged by excessive bending. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the present invention, a bending-resistant MT short jumper includes an MT jumper 1 and a central bending-resistant plate 3. The MT jumper 1 has fiber optic connectors 2 at both ends. The central bending-resistant plate 3 has bending-resistant support plates 4 hinged at both ends. A telescopic adjustment rod 5 is inserted into one end of the bending-resistant support plate 4. A jumper fixing seat is provided at one end of the telescopic adjustment rod 5 through a connecting rod 6. The jumper fixing seat is clamped and fixed to the outside of both ends of the MT jumper 1. The middle part of the MT jumper 1 is connected and fixed by the central bending-resistant plate 3 and two bending-resistant support plates 4. The bending-resistant support plates 4 are symmetrically arranged about the central bending-resistant plate 3. Both the bending-resistant support plate 4 and the central bending-resistant plate 3 are alloy rectangular plates, so that the central bending-resistant plate 3 and the bending-resistant support plates 4 can be used to resist bending in the middle part of the MT jumper 1, preventing excessive bending damage to the middle part of the MT jumper 1.

[0022] like Figure 1 and Figure 3 As shown, in order to bend and shape the middle part of the MT jumper, a hinge seat 14 is provided on one side of the central anti-bending plate 3 and the anti-bending support plate 4. The two hinge seats 14 are hinged together by a pin 12. A second locking bolt 13 is provided on one side of the hinge seat 14, so that the anti-bending support plate 4 can be rotated and adjusted relative to the central anti-bending plate 3 by means of the hinge seat 14 and the pin 12, thereby enabling the bending and shaping of the middle part of the MT jumper.

[0023] like Figure 1 and Figure 2As shown, in order to fix the central anti-bending plate 3 and the anti-bending support plate 4 to the outside of MT jumpers of different lengths, the telescopic adjustment rod 5 is also inserted into the insertion slot inside one end of the anti-bending support plate 4. A first locking bolt 10 is provided on the lower side of one end of the anti-bending support plate 4, so that by adjusting the depth of the telescopic adjustment rod 5 inserted into the anti-bending support plate 4, the distance between the two jumper fixing seats can be adjusted, thereby facilitating the fixing of the central anti-bending plate 3 and the anti-bending support plate 4 to the outside of MT jumpers of different lengths, and the first locking bolt 10 is used to lock the telescopic adjustment rod 5 inserted into the anti-bending support plate 4.

[0024] like Figure 2 and Figure 3 As shown, in order to clamp and fix the jumper holder to the outside of both ends of the MT jumper, the jumper holder also includes a fixed clamp 7. A movable clamp 8 is hinged to the upper side of the fixed clamp 7 via a hinge 9. The movable clamp 8 and the fixed clamp 7 are connected and fixed at one end by a connecting arm 16 and a fixing bolt 11. Both the movable clamp 8 and the fixed clamp 7 are provided with a fixing groove 15 inside, and the inner wall of the fixing groove 15 is provided with an anti-slip pad. This makes it easy to clamp and fix the jumper holder to the outside of both ends of the MT jumper using the movable clamp 8 and the fixed clamp 7. The clamping and fixing stability is high, and the assembly and disassembly are convenient and quick.

[0025] The working principle and usage process of this utility model are as follows: In use, the central anti-bending plate 3 and the anti-bending support plate 4 are installed on the outer side of the middle part of the MT jumper 1 through the jumper fixing seat, so that the middle part of the MT jumper 1 can be subjected to anti-bending treatment to prevent excessive bending damage to the middle part of the MT jumper 1. Since one end of the anti-bending support plate 4 is provided with a jumper fixing seat through the telescopic adjustment rod 5 and the connecting rod 6, the distance between the two jumper fixing seats can be adjusted by adjusting the depth of the telescopic adjustment rod 5 inserted into the anti-bending support plate 4, thereby facilitating the fixing of the central anti-bending plate 3 and the anti-bending support plate 4 to the outside of MT jumpers of different lengths.
