Description

Technical Field

[0001] This utility model relates to a tool for straightening loose twisted-pair cables. Background Technology

[0002] Twisted pair cable is a common type of wiring made by twisting two insulated wires together according to certain specifications. The electromagnetic waves radiated by each wire during transmission are canceled out by the electromagnetic waves emitted by the other wire, effectively reducing the degree of signal interference. It is the most commonly used transmission medium in low-voltage integrated cabling projects. When installing the end of a twisted pair cable, the twisted wires need to be loosened and straightened.

[0003] Chinese patent CN222673587U discloses a twisted-pair cable untangling and straightening device, which includes a clamping rod. A handle and a connecting shell are slidably connected to the outer side of the clamping rod, and the handle is fixed to the connecting shell. A spring is sleeved on the outer side of the clamping rod and inside the connecting shell. A cable placement groove is formed inside the clamping rod at the end away from the handle. An inlet and a movable groove are formed inside the clamping rod and outside the cable placement groove. A support shaft is provided inside the movable groove and fixed to the clamping rod. A clamping arc block is rotatably connected to the outer side of the support shaft. A first pushing groove is formed inside the connecting shell and on the side of the movable groove away from the cable placement groove. One side of the clamping arc block is located inside the cable placement groove and fits against it, while the other side is located inside the first pushing groove and fits against it. Clearly, this twisted-pair cable untangling and straightening device has a complex structure, high production cost, and correspondingly high selling price, which is not conducive to market promotion and use.

[0004] With the development of communication technology and the economy, high-quality twisted-pair cables are being used more and more widely, and competition is becoming increasingly fierce. The need for a simpler, easier-to-produce, more efficient and high-quality twisted-pair cable straightening tool is becoming more urgent. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, in view of the shortcomings of existing twisted pair untwisting and straightening devices, which have complex structures and high production costs, this utility model provides a twisted pair untwisting and straightening tool with a simple structure and easier production.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A twisted-pair cable straightening tool includes a main body and a movable part, characterized by the following structural features:

[0008] The front end of the main body is provided with a through groove, and the rear end is provided with a rotating part;

[0009] The movable component is installed in the through groove and hinged to the main body component, and a reset component is installed between the movable component and the main body component;

[0010] The movable part has a pressing end and a fastening end. In the initial state, the fastening end extends out relative to the through groove, and the pressing end forms an angle of less than or equal to 90 degrees with the bottom surface of the through groove.

[0011] A further improvement to the above scheme is that the depth of the front section of the through groove is less than the depth of the rear section, so that there is a step between the front and rear sections of the through groove, and the pressure end is in contact with the step in the initial state.

[0012] A further improvement to the above solution is that the rotating part is connected to the rotating tool.

[0013] A further improvement to the above solution is that the reset element is a tension spring connected between the movable element and the rear end of the main body.

[0014] A further improvement to the above solution is that a limiting block is provided at the front end of the cable channel, and a twisted pair cable entry channel is formed between the bottom surface of the limiting block and the bottom surface of the cable channel.

[0015] A further improvement to the above solution is that the main body and the limiting block are an integral structure.

[0016] A further improvement to the above solution is that the reset element is a compression spring or torsion spring installed between the movable element and the limiting block.

[0017] A further improvement to the above solution is that the reset member is an elastic protrusion provided on the limiting block, and the elastic protrusion abuts against the buckle end of the movable member.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention requires only one main component and one movable component to straighten the twisted pair cable. The overall structure is simple, easier to manufacture, more portable, more efficient to use, and more conducive to market promotion. Attached Figure Description

[0032] The present invention will be further described below with reference to specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0033] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Please see Figure 1 - Figure 2 This utility model's twisted-pair cable straightening tool, in embodiment one, includes a main body 1 and a movable part 2. The main body 1 has a cable passage groove 11 at its front end and a rotating part 12 at its rear end. The rotating part 12 can be rotated manually or connected to a rotating tool, which then rotates the part. The movable part 2 has a pressing end 21 and a latching end 22, and is disposed within the cable passage groove 11 and hinged to the main body 1 via a hinge shaft. A reset part 3 is connected and installed between the movable part 2 and the rear end of the main body 1. In the initial state, the latching end 22 extends relative to the cable passage groove 11, and the pressing end 21 forms an angle α less than or equal to 90 degrees with the bottom surface of the cable passage groove 11.

[0036] In this embodiment, the reset element 3 is a tension spring 31 installed between the buckle end 22 and the rear end of the main body 1.

[0037] When using this invention, a rotating tool, such as an electric drill, can be used to clamp the rotating part 12. Then, the twisted pair cable is inserted into the through groove 11 from the front end. The force of the twisted pair cable is used to push open the pressure end 21 of the movable part 2, and after the twisted pair cable passes through the pressure end 21, the twisted pair cable is pulled back slightly and the pressure end 21 is used to hold the twisted pair cable in place. Then, the twisted pair cable is pulled by hand, and the rotating tool is used to drive the main body 1 to rotate in the opposite direction of the twisted pair cable. This will loosen and straighten the twisted pair cable. Finally, the buckle end 22 of the movable part 2 is turned to rotate the buckle end of the movable part 2 away from the reset part 3. At the same time, the pressure end 21 moves away from the bottom surface of the through groove 11. The straightened twisted pair cable is then loosened and can be pulled out.

[0038] Please see Figure 3 - Figure 4 The second embodiment of the twisted-pair cable straightening tool of this utility model has a general structure similar to that of the first embodiment, except that: the front section of the through groove 11 is less deep than the rear section, creating a step 111 between the front and rear sections of the through groove 11. The end of the pressure end 21 initially fits against the step 111, enhancing the clamping stability of the twisted-pair cable when straightening it. A limiting block 13 is provided at the front end of the through groove 11, forming a twisted-pair cable entry channel between the bottom surface of the limiting block 13 and the bottom surface of the through groove 11. The limiting block 13 restricts the range of rotation of the clamping end of the movable part 2 away from the reset part 3. It should be noted that the limiting block 13 in this utility model can be an independent component or integrally formed with the main body 1.

[0039] Please see Figure 5The structure of the twisted pair cable straightening tool in embodiment three is generally the same as that in embodiment two, except that the limiting block 13 is an independent component and the reset component 3 is a torsion spring 32 installed between the movable component 2 and the limiting block 13.

[0040] Please see Figure 6 The structure of the twisted pair cable straightening tool in embodiment four is generally the same as that in embodiment two, except that the reset component 3 is a compression spring 33 installed between the buckle end 22 of the movable component 2 and the limiting block 13.

[0041] Please see Figure 7 The structure of Embodiment 5 of the twisted pair cable straightening tool is generally the same as that of Embodiment 2, except that the reset member 3 is an elastic protrusion 131 provided on the limiting block 13, and the elastic protrusion 131 abuts against the buckle end 22 of the movable member 2.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model should fall within the protection scope of the technical solution of this utility model.
