Description
Technical Field
[0001] This utility model relates to the field of straightening tools, specifically to a twisted-pair cable straightener. 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] When professionals use traditional tools to straighten a twisted pair cable, the ends of the twisted pair cable are easily stretched open as the cable is straightened. Since the ends of the core wires are no longer under stress, they cannot be straightened again. This application aims to optimize and solve the problem that the ends of the twisted wires cannot be straightened when straightening a twisted pair cable. Utility Model Content
[0004] To address the problem that traditional tools are not easy to straighten the ends of twisted wires, this invention provides a twisted wire straightener.

[0006] On one hand, this utility model provides a twisted-pair cable straightener for straightening two core wires twisted together in a twisted-pair cable, characterized by comprising:
[0007] The handle body has a bi-directional through groove at the end;
[0008] The insert is connected to the bottom of the groove and extends along the extension direction of the handle. Two straightening grooves are formed between the insert and the two side walls of the groove. The side of the straightening groove facing the insert is concave, and the axial direction of the concave structure extends along the extension direction of the insert.
[0009] Furthermore, the concave structure includes at least one of an arcuate surface and a non-arcuate surface.

[0011] And / or, at least one binding groove is provided on the side of the insert for the core wire to pass through when straightened;
[0012] And / or, the concave structure is a minor arc surface.
[0013] Furthermore, the minimum width of the straightening groove is greater than or equal to the diameter of the core wire.
[0014] Furthermore, the insert includes a cylindrical section connected to the bottom of the groove, and the straightening groove is concentrically arranged with the cylindrical section.
[0015] Furthermore, the groove-shaped portion includes a first opening and a second opening, and the first opening, the straightening groove, and the second opening are connected in sequence.
[0016] Furthermore, the width of the first opening is greater than or equal to the sum of the diameters of the two core wires, the width of the second opening is greater than or equal to the diameter of the core wire, and the width of the first opening or the second opening is less than the sum of the width of the plug and twice the diameter of the core wire.
[0017] Furthermore, the first opening and the straightening groove are connected by an arc-shaped transition.
[0018] And / or, the straightening groove and the second opening are connected by an arc-shaped transition.

[0023] The beneficial effects achieved by this utility model are as follows:
[0024] This utility model discloses a twisted-pair cable straightener for straightening two twisted core wires in a twisted-pair cable. The straightener includes a handle with a bidirectional through-hole at one end. A post is connected to the bottom of the through-hole along the extension direction of the handle. Two straightening grooves are formed between the post and the two side walls of the through-hole. The side of the straightening groove facing the post is concave, and the axial direction of the concave structure extends along the extension direction of the post. The twisted-pair cable straightener is used for straightening core wires, especially for separating and straightening two twisted core wires. The handle is used for gripping, and the post is inserted between the two twisted core wires, placing each core wire in the post. Between the two side walls of the post and the groove section, the wound core wires are separated and straightened by pushing them towards the ends of the two core wires under the action of the post. At the same time, because a straightening groove is set between the post and the groove section, and the side of the straightening groove facing the post is concave, with the axial direction of the concave structure extending along the extension direction of the post, when the core wire passes through the straightening groove, the core wire is subjected to the pressure of the post and the concave structure of the straightening groove, which improves the straightening effect of the twisted pair, shortens the distance that the end of the twisted pair is stretched, and improves the straightening effect of the entire twisted pair. The twisted pair straightener can optimize and solve the problem of the end of the twisted pair not being straightened when straightening the twisted pair with a simple structure. It is easy to operate and suitable for widespread use. Attached Figure Description

[0039] This application discloses a twisted-pair straightener for straightening two core wires twisted together in a twisted-pair cable. The twisted-pair straightener includes a handle 100, and a bidirectional through groove 200 is provided at the end of the handle 100. A post 300 is connected to the bottom of the groove 200 along the extension direction of the handle 100. Two straightening grooves 210 are formed by spacing between the post 300 and the two side walls of the groove 200. The side of the straightening groove 210 facing the post 300 is concave, and the axial direction of the concave structure extends along the extension direction of the post 300.
[0040] In this embodiment, the twisted-pair straightener is used to straighten twisted-pair cables, particularly to separate and straighten two core wires that are twisted together in a twisted-pair cable. The handle 100 is used for gripping, and the insert 300 is inserted between the two twisted core wires, placing each core wire between the insert 300 and the two side walls of the groove 200. By pushing the two core wires towards their ends, the twisted core wires are separated and straightened by the action of the insert 300. Simultaneously, a straightening mechanism is provided between the insert 300 and the groove 200. The straightening slot 210 has a concave structure on the side facing the insertion post 300. The axial direction of the concave structure extends along the extension direction of the insertion post 300. When the core wire passes through the straightening slot 210, the core wire is subjected to the pressure of the insertion post 300 and the concave structure of the straightening slot 210, which improves the straightening effect of the twisted pair, shortens the distance that the end of the twisted pair is stretched, and improves the straightening effect of the entire twisted pair. The twisted pair straightener can achieve and improve the separation and straightening of the twisted pair core wires through a simple structure and action. It is easy to operate and suitable for widespread use.
[0041] In an optional or preferred embodiment, the concave structure includes at least one of an arcuate surface and a non-arcuate surface. This can be understood as the concave structure being a single arcuate surface, a non-arcuate surface, or a combination of arcuate and non-arcuate surfaces. For example, refer to the attached diagram. Figure 3 , Figure 4 As shown.
[0042] In an optional or preferred embodiment, the concave structure is a slightly curved surface to facilitate the smooth entry of the core wire into the straightening groove 210.
[0043] In an optional or preferred embodiment, at least one binding groove 240 is provided on the side of the groove portion 200 for the core wire to pass through when straightened, and the binding groove 240 extends along the opening direction of the groove portion 200; such as Figure 5 As shown, the binding groove 240 can squeeze and bind the passing core wire, thereby further improving the straightening effect of the core wire.
[0044] In an optional or preferred embodiment, the width of the straightening groove 210 is greater than or equal to the diameter of the core wire.
[0045] In this embodiment, the width of the straightening groove 210 is set to be greater than or equal to the diameter of the core wire, so that the core wire can easily enter the straightening groove 210 to achieve the straightening operation of the core wire; the width of the straightening groove 210 should be understood as the distance between the concave structure of the straightening groove 210 and the insertion post 300; if the width of the straightening groove 210 is not regular, it can be defined as the minimum width of the straightening groove 210 being greater than or equal to the diameter of the core wire, so that the core wire can pass through smoothly.
[0046] In an optional or preferred embodiment, the insert 300 includes a cylindrical section connected to the bottom of the slot 200, and the straightening slot 210 is concentrically arranged with the cylindrical section; the concentric arrangement of the straightening slot 210 with the cylindrical section allows the core wire to pass through the straightening slot 210 more evenly, thereby further improving the purpose of straightening the core wire.
[0047] In an optional or preferred embodiment, the slotted portion 200 includes a first opening 220 and a second opening 230, wherein the first opening 220, the straightening slot 210, and the second opening 230 are sequentially connected to form a slotted structure that facilitates the entry, straightening, and exit of the core wire; for example, refer to the attached drawing. Figure 3 When in use, the network cable is positioned to the left of the second opening 230, and the core wires in the network cable pass through the first opening 220, the straightening groove 210 and the second opening 230 from right to left.
[0048] In an optional or preferred embodiment, such as Figure 3As shown, the width of the first opening 220 is greater than or equal to the sum of the diameters of the two core wires, so that the twisted pair can enter the slot section 200; the width of the second opening 230 is greater than or equal to the diameter of the core wire, so that the core wire can pass through; the width of the first opening 220 or the second opening 230 is less than the sum of the width of the insert 300 and twice the diameter of the core wire, so that when the core wire passes through the straightening slot 210, the core wire is subjected to the pressure of the insert 300 and the concave structure of the straightening slot 210. It can be understood that the width of the first opening 220 should be understood as the minimum distance between the two side walls of the first opening 220, and the width of the second opening 230 should be understood in the same way. The direction of the width of the insert 300 is parallel to the direction of the width of the first opening 220 or the second opening 230; the first opening 220 or the second opening 230 can be designed as an opening structure with parallel side walls (e.g. Figure 3 The first opening 220 and the second opening 230 shown can also be designed as an open-type opening structure (such as...). Figure 4 The second opening 230 shown can also be designed as an openable opening structure (such as...). Figure 4 The first opening 220 shown above, including but not limited to, is as follows: Figure 3 and 4 As shown.
[0049] In an optional or preferred embodiment, the first opening 220 and the straightening groove 210 are connected by an arc-shaped transition, which facilitates the smooth entry of the core wire into the straightening groove 210; the straightening groove 210 and the second opening 230 are connected by an arc-shaped transition, which facilitates the smooth passage of the core wire from the straightening groove 210 into the second opening 230.
[0050] In an optional or preferred embodiment, the head of the insert 300 is an insertion guide end, which guides the insert 300 to be inserted between two wound core wires. The insertion guide end includes one or more combinations of a guide slope 310, an arc surface 320, a plane 330, a conical structure, or a semi-conical structure. For example, refer to the attached drawing. Figure 1 , Figure 2 , Figure 5 The guide slope 310 converges into a tip at the head of the insert 300. During use, the tip of the insert 300 facilitates insertion into the gaps between the twisted core wires and widens the gaps, thus smoothly guiding the two core wires into the straightening groove 210; for example, refer to the attached... Figure 6 The insertion guide end includes a combination of an arc-shaped surface 320 and a flat surface 330.
[0051] In an optional or preferred embodiment, the bottom of the insert 300 and the groove 200 are integrally connected and the connection has an arc-shaped reinforcing root, which improves the strength between the insert 300 and the groove 200 and prevents the insert 300 from tilting or breaking when the core wire moves frequently between the straightening groove 210 and the root of the insert 300; furthermore, the groove 200 and the handle 100 are integrally connected to improve the compactness and reliability of the overall structure.
[0052] In an optional or preferred embodiment, the handle 100 is a column with a rectangular cross-section, and the end of the handle has a groove 200. The bottom of the groove 200 is integrally connected to the insert post 300, and the three are integrally formed. Furthermore, the handle 100 has rounded corners between each two adjacent surfaces for easy gripping and use.
