A special fixture for high-speed wire wrapping

Abstract

This application relates to the field of wrapping fixture technology, and particularly to a special fixture for wrapping high-speed wires. A mold body is installed on a wrapping machine, with a through-hole (prism-shaped) for wire passing through it. Two circular holes are also formed around the outer periphery of the through-hole on the mold body. The core wire passes through the through-hole, and the ground wire passes through the circular holes, entering the wrapping machine. The machine wraps an aluminum foil shielding layer around the core wire and ground wire. The two circular holes are symmetrically positioned on either side of the through-hole, and the perpendicular bisector of the circular holes does not coincide with the perpendicular bisector of the through-hole. During the wrapping process, the ground wires on both sides are offset towards the ends of the core wire under the wrapping force, ensuring the ground wires are positioned at both ends of the core wire, thus improving the shielding wrapping quality and the forming quality of the high-speed wire.

Description

Technical Field

[0001] This application relates to the field of wrapping fixture technology, and in particular to a special fixture for high-speed line wrapping. Background Technology

[0002] Currently, flat high-speed wires consist of two or more sets of core wires arranged side by side. The ground wire needs to be symmetrically positioned on both sides of the core wire. Then, a shielding layer is wrapped around the outer periphery by a wrapping machine to ensure that the ground wire is symmetrically positioned on both sides of the core wire. However, during the wrapping process, the tension of the wrapping machine can cause the ground wire to shift, resulting in the ground wire not being positioned on both sides of the core wire. This deviation in the ground wire's position will affect the subsequent wire production process, thus affecting the quality of the wire forming. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a special fixture for high-speed wire wrapping, including a mold body, a wire-passing hole is formed through the mold body, the wire-passing hole is prismatic, and two circular holes are formed through the mold body on the outer periphery of the wire-passing hole, the two circular holes are symmetrically arranged on both sides of the wire-passing hole, and the perpendicular bisector of the circular holes does not coincide with the perpendicular bisector of the wire-passing hole.

[0004] Preferably, the distance between the perpendicular bisector of the circular hole and the perpendicular bisector of the through hole is D, and the ratio of the width of the long side of the through hole to the value of D is 13-15.

[0005] Preferably, the wire-passing hole is located on one side of the mold body, and the other side of the mold body is provided with a first conical groove, a straight groove and a second conical groove in sequence, with the second conical groove connected to the wire-passing hole.

[0006] Preferably, the wire hole and the end face of the mold body form a first rounded corner, and the wire hole and the second conical groove are connected by a second rounded corner.

[0007] Preferably, the first conical groove and the straight groove are connected by a third fillet.

[0008] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By installing a mold body on the wrapping machine, a through-hole is opened through the mold body. The through-hole is prismatic in shape, and two circular holes are opened through the outer periphery of the through-hole on the mold body. Then, the core wire passes through the through-hole and the ground wire passes through the circular holes, entering the wrapping machine. The wrapping machine wraps an aluminum foil shielding layer around the core wire and the ground wire. The two circular holes are symmetrically arranged on both sides of the through-hole, and the perpendicular bisector of the circular holes does not coincide with the perpendicular bisector of the through-hole. Therefore, during the wrapping process, the ground wires on both sides are offset towards the two ends of the core wire under the action of the wrapping force, so that the ground wire is located at the two ends of the core wire, ensuring the position of the ground wire, thereby improving the shielding wrapping quality and the forming quality of the high-speed line.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0014] Example

[0015] To address the aforementioned technical problems, this embodiment provides a special fixture for high-speed wire wrapping, such as... Figure 1-2 As shown, the device includes a mold body 10, which is mounted on a wrapping machine. A wire-passing hole 20 is formed through the mold body 10. The wire-passing hole 20 is prismatic and matches the shape of the core wire. Two circular holes 30 are formed through the outer periphery of the wire-passing hole 20 on the mold body 10. The core wire passes through the wire-passing hole 20, and the ground wire passes through the circular holes 30, entering the wrapping machine. The wrapping machine wraps an aluminum foil shielding layer around the core wire and ground wire. The two circular holes 30 are symmetrically arranged on both sides of the wire-passing hole 20, and the perpendicular bisector of the circular holes 30 does not coincide with the perpendicular bisector of the wire-passing hole 20. Therefore, during the wrapping process, the ground wires on both sides are offset towards the ends of the core wire under the wrapping tension, ensuring the ground wires are located at the ends of the core wire, thus improving the shielding wrapping quality and the forming quality of the high-speed wire.

[0016] Specifically, the distance between the perpendicular bisector of the circular hole 30 and the perpendicular bisector of the wire-passing hole 20 is D, the width of the long side of the wire-passing hole 20 is W, and the ratio of W to D is 13-15. Experiments have shown that a ratio of W to D of 15 is optimal. For example, the width of the long side of the wire-passing hole 20 is W = 4.5mm, and D = 0.3mm. Therefore, after actual production and testing, setting the ratio of W to D to 15 ensures that the ground wire is symmetrically located at both ends of the core wire after wrapping, thereby improving the forming quality of the wire.

[0017] Furthermore, such as Figure 3 As shown, the wire passage hole 20 is located on one side of the mold body 10. On the other side of the mold body 10, a first conical groove 11, a straight groove 12, and a second conical groove 13 are sequentially formed. The second conical groove 13 connects to the wire passage hole 20. The wire passage hole 20 and the end face of the mold body 10 form a first fillet 21, and the wire passage hole 20 and the second conical groove 13 are connected by a second fillet 14. The first conical groove 11 and the straight groove 12 are connected by a third fillet 15, thereby improving the smoothness of the internal cavity of the mold body 10, reducing the edges inside the cavity, and preventing friction between the wire and the edges of the cavity during winding production, thus avoiding damage to the wire surface and improving the quality of the wire surface.

[0018] In summary, the solution proposed in this application involves installing a mold body on a wrapping machine. A through-hole, prismatic in shape, is formed in the mold body, and two circular holes are formed around the outer periphery of the through-hole. The core wire passes through the through-hole, and the ground wire passes through the circular holes, entering the wrapping machine. The machine wraps an aluminum foil shielding layer around the core wire and ground wire. The two circular holes are symmetrically positioned on either side of the through-hole, and the perpendicular bisector of the circular holes does not coincide with the perpendicular bisector of the through-hole. During the wrapping process, the ground wires on both sides are offset towards the ends of the core wire under the wrapping force, ensuring the ground wires are positioned at both ends of the core wire and thus improving the forming quality of the high-speed line.

[0019] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
