Description

Technical Field

[0001] This utility model relates to the field of repair tool technology, specifically to a combing device for twisted-pair cables. Background Technology

[0002] Network cables are typically four pairs of eight-core twisted-pair cables. When crimping RJ45 connectors, it is necessary to first untangle the cores of the network cable. Currently, the untangle method is usually to use the fingertips and a screwdriver. The twisted cores need to withstand a lot of external force to separate them segment by segment, which is not only harmful to the hands and inefficient, but also damages the insulation layer of the cores, affecting the quality of the crimp. Especially in low-voltage construction or maintenance work by property management and IT departments, there is a lot of RJ45 connector crimping work, and prolonged untanglement of twisted-pair cables will make the above problems more prominent. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a combing device for twisted-pair cables that is convenient and efficient in combing twisted-pair cables.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A core-combing device for twisted-pair cables includes a fixed sleeve, a rotating part rotatably mounted inside the fixed sleeve, and two separation holes vertically spaced apart on the rotating part, through which each core of the twisted-pair cable can pass.

[0006] Working principle: During the combing process, the ends of the twisted pair wires are first separated manually. The two ends of the twisted pair wires are then fed into their respective separation holes. After holding the retaining sleeve with one hand, the entire network cable is pushed into the retaining sleeve. Due to the spiral winding of the twisted pair and the certain spacing of the separation holes, the twisted pair wires are separated. Since the rotating part can rotate within the retaining sleeve, it can rotate in the direction of the separation of the twisted pair wires, thus preventing the rotating part from getting stuck with the twisted pair wires.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] By setting a fixed sleeve and a rotating part, the two wire cores are fixed and then pushed to separate the network cable. This makes the separation of twisted pairs more efficient, and the fingers only need to control the network cable and the fixed sleeve to apply force, so it will not hurt the hands even after long-term work.

[0009] In a preferred embodiment of the present invention, the fixed sleeve is provided with a limiting part, which allows the rotating part to rotate only in one direction.

[0010] Beneficial effects: When the wire is pushed in, the rotating part rotates clockwise. After it is fully pushed in, it needs to be pulled out. At this time, the two wire cores may still be in a bent state, and the two separated wire cores are still in the same direction of rotation as when they were wrapped. Therefore, when pulling out, the rotating part is forced to rotate counterclockwise. After setting the limiting part, the rotating part cannot rotate counterclockwise, which will straighten the two wire cores. Therefore, this device can not only separate the wire cores, but also straighten the separated wire cores, thus improving the efficiency of combing.

[0011] In a preferred embodiment of the present invention, the rotating part includes an outer ring and two inner rings, the two inner rings respectively corresponding to two separation holes, the two inner rings being located inside the outer ring and integrally formed with the outer ring.

[0012] Beneficial effects: By setting an outer ring and an inner ring, and using the inner ring as a separation hole, separation can be achieved. The two are integrally formed, which can save materials and production costs.

[0013] In a preferred embodiment of this utility model, the rotating part includes a rotating column, and the two separation holes are vertically arranged on the rotating column.

[0014] Beneficial effects: The use of rotating columns results in higher structural strength and makes it less prone to bending and deformation during combing.

[0015] In a preferred embodiment of this utility model, a plurality of ball bearings are installed between the rotating column or outer ring and the inner wall of the fixed sleeve.

[0016] Beneficial effect: By setting ball bearings, the friction between the rotating part and the fixed sleeve is reduced, making the rotation of the rotating part smoother.

[0017] In a preferred embodiment of the present invention, the fixed sleeve is provided with a limiting part, which includes an inner ratchet and a pawl. The inner ratchet is fixedly installed on the inner wall of the fixed sleeve, and the pawl is installed on the rotating column or the outer ring and cooperates with the ratchet, so that the fixed plate can only rotate in one direction.

[0018] Beneficial effect: By utilizing the principle of ratchet and pawl, the rotating column can rotate in one direction, thereby straightening the wire core.

[0019] In a preferred embodiment of this utility model, a reinforcing column is fixedly connected between the two inner rings.

[0020] Beneficial effect: By setting a reinforcing column between the two inner rings, the overall structural strength of the rotating part can be increased, making it less prone to deformation. Attached Figure Description

[0024] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0025] In the description of this application, the terms "first", "second", "side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] See Figure 1 , 2 As shown, the core-combing device for twisted-pair cables in this embodiment includes a fixed sleeve 1, a rotating part, and a limiting part.

[0027] The rotating part includes an outer ring 21, two inner rings 22, and a reinforcing column 23. The outer ring 21, two inner rings 22, and reinforcing column 23 are integrally formed. The cavity in the inner ring 22 serves as a separation hole 24. Multiple ball bearings 25 are installed between the outer ring 21 and the fixing sleeve 1. The diameter of the separation hole 24 is 2.5 mm, the outer diameter of the outer ring 21 is 8.75 mm, and the outer diameter of the fixing sleeve 1 is 10 mm. Figure 2 In the figure, h indicates that the height of the outer ring 21 is 3 mm.

[0028] In other embodiments, the rotating part may be a rotating column, with the two separation holes 24 vertically arranged on the rotating column, and a ball bearing may be installed between the rotating column and the fixed sleeve 1.

[0029] The limiting part includes an inner ratchet 31 and a pawl 32. The inner ratchet 31 is fixedly installed on the inner wall of the fixed sleeve 1, and the pawl 32 is installed on the outer ring 21 and cooperates with the ratchet 31, so that the fixed plate can only rotate clockwise. The arc arrow in the figure indicates the direction of rotation.

[0030] Specific usage (work) process:

[0031] During the combing process, the ends of the twisted pair wires are first separated manually. The two ends of the twisted pair wires are then fed into the corresponding separation holes 24. After holding the fixing sleeve 1 with one hand, the entire network cable is pushed into the fixing sleeve 1. Because the twisted pair wires are spirally wound and the separation holes 24 have a certain interval, the outer ring 21 and the inner ring 22 rotate clockwise, causing the twisted pair wires to be separated.

[0032] After being fully pushed in, it needs to be pulled out. At this time, the two cores may still be in a bent state, and the two separated cores are still in the same direction of rotation as when they were wrapped. Therefore, when pulling out, the rotating part will be forced to rotate counterclockwise. After setting the limiting part, the pawl 32 locks the ratchet 31, and the rotating part cannot rotate counterclockwise, which will straighten the two cores. Therefore, this device can not only separate the cores, but also straighten the separated cores, thus improving the efficiency of combing.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
