Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a high-frequency cable longitudinal wrapping mold. Background Technology

[0002] Because high-frequency cables are highly susceptible to electromagnetic interference, during the production process, aluminum foil or copper foil is used to longitudinally wrap the core wire to ensure stable transmission of high-frequency signals. Existing patents, such as Chinese patent application number 202220774072.1, disclose a longitudinal wrapping mold for producing dual-core high-speed cables. This mold includes a longitudinal wrapping assembly and a support rod for mounting the assembly. The longitudinal wrapping assembly is detachably and fixedly connected to the support rod. In use, the first or second core wire is passed through the core wire hole of the longitudinal wrapping assembly, and the wrapping material is passed through the wrapping material hole of the assembly, thus wrapping the first or second core wire to form the finished cable. Furthermore, the longitudinal wrapping assembly can be detachably and fixedly connected to the support rod for easy replacement. This results in easy installation and maintenance, a simple structure, small size, and convenient use. While this patent document enables the wrapping film to be wrapped around the core wire, some high-frequency cables contain ground wires. Therefore, the ground wires need to be routed during the production of high-frequency cables containing ground wires, and this patent document cannot implement the routing of ground wires, meaning it cannot perform the wrapping production of high-frequency cables containing ground wires. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a high-frequency cable longitudinal wrapping mold.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-frequency cable longitudinal wrapping mold includes a mounting base, a support rod mounted on the mounting base, a lead-out end mounted on the support rod away from the mounting base, and multiple longitudinal wrapping molds arranged in a straight line on the support rod. The lead-out end has a lead-out hole in its center, and each of the multiple longitudinal wrapping molds has a core wire hole in its center. The lead-out hole and the core wire holes of the multiple longitudinal wrapping molds are coaxially arranged. Each of the multiple longitudinal wrapping molds has a wrapping groove, which gradually converges and wraps around the corresponding core wire hole. Grounding holes are provided on both sides of the lead-out end and on both sides of the multiple longitudinal wrapping molds. The lead-out hole is located between two grounding holes on the lead-out end. In the longitudinal wrapping mold, the core wire hole and the wrapping groove are both located between two grounding holes in the longitudinal wrapping mold.

[0006] Furthermore, in addition to the first and last longitudinal wrapping molds, the other longitudinal wrapping molds are provided with first opening slots on both sides, and one of the first opening slots is connected to a grounding hole of the longitudinal wrapping mold.

[0007] Furthermore, a limiting step is provided on the bottom wall of the first opening groove near the opening position.

[0008] Furthermore, a second opening slot is provided on both sides of the outlet head, and one of the second opening slots is connected to a ground wire hole of the outlet head.

[0009] Furthermore, the longitudinal molding and the support rod are detachably connected.

[0010] Furthermore, a first slider is provided on the bottom surface of the longitudinal mold, and a groove is recessed on the top surface of the support rod, with the first slider slidably connected to the groove.

[0011] Furthermore, the lead wire is detachably connected to the support rod.

[0012] Furthermore, a second slider is provided on the bottom surface of the lead wire, and the second slider is slidably connected to the groove.

[0013] Furthermore, the bottom wall of the chute is provided with multiple locking holes, which are equally spaced along the length of the chute. The locking holes are detachably connected to locking fasteners, which are used to lock the longitudinal wrapping mold and the wire end to the support rod.

[0014] Furthermore, a mounting ring is provided at the end of the mounting base away from the wire outlet, and an arc guide groove is recessed on the top surface of the mounting base, while an arc surface that matches the concavity and convexity of the arc guide groove is provided on the bottom surface of the support rod.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the wire core passes through the core wire holes of multiple longitudinal wrapping dies and the wire outlet holes of the wire outlet head in sequence. The wrapping film passes through the wrapping grooves of multiple longitudinal wrapping dies and the wire outlet holes of the wire outlet head in sequence. The core wire, wrapping film, and wrapping tape on the wrapping machine, which are output through the wire outlet head, are wound together to form a high-frequency cable and then connected to the traction machine. During the process of the traction machine continuously pulling the high-frequency cable, the wrapping film will be wound around the core wire under the guidance of multiple wrapping grooves that are gradually approaching the corresponding core wire holes, so as to form a core wire wrapped with wrapping film. After the core wire wrapped with wrapping film is output through the wire outlet head, the wrapping machine wraps the wrapping tape around the core wire wrapped with wrapping film, that is, the wrapping tape is wrapped around the wrapping film after wrapping, so that the wrapping film can be firmly wrapped around the core wire. When a high-frequency cable has a single or double ground wire, the ground wire passes sequentially through the ground wire holes of multiple longitudinal wrapping dies and the ground wire hole of the outlet. The ground wire holes not only allow the ground wire to pass through but also guide and limit its movement, improving the positional accuracy and stability of the ground wire. After the ground wire exits from the outlet, the wrapping machine winds the ground wire and the core wire wrapped with the wrapping film together using wrapping tape to form a high-frequency cable with a ground wire. This invention features ground wire holes for the ground wire to pass through, resulting in high positional accuracy and good movement stability, enabling the production of high-frequency cables with a ground wire.

Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a high-frequency cable longitudinal wrapping mold, which includes a mounting base 1, a support rod 2 mounted on the mounting base 1, a wire outlet 3 mounted on the end of the support rod 2 away from the mounting base 1, and multiple longitudinal wrapping molds 4 arranged in a straight line on the support rod 2. The wire outlet 3 has a wire outlet hole 5 in its center, and each of the multiple longitudinal wrapping molds 4 has a core wire hole 6 in its center. The wire outlet hole 5 and the core wire holes 6 of the multiple longitudinal wrapping molds 4 are coaxially arranged. Each of the multiple longitudinal wrapping molds 4 has a wrapping groove 7, which gradually converges and wraps around the corresponding core wire hole 6. The wrapping groove 7 is located around the periphery of the core wire hole 6. Grounding holes 8 are provided on both sides of the wire outlet 3 and both sides of the multiple longitudinal wrapping molds 4. The wire outlet hole 5 is located between two grounding holes 8 of the wire outlet 3. In the longitudinal wrapping mold 4, the core wire hole 6 and the wrapping groove 7 are both located between two grounding holes 8 of the longitudinal wrapping mold 4. The wrapping film can be aluminum foil or copper foil, etc.

[0022] In practical applications, the wire core passes sequentially through the core wire holes 6 of multiple longitudinal wrapping dies 4 and the outlet holes 5 of the outlet head 3. The wrapping film passes sequentially through the wrapping grooves 7 of multiple longitudinal wrapping dies 4 and the outlet holes 5 of the outlet head 3. The core wire, wrapping film, and wrapping tape on the wrapping machine, which are output from the outlet head 3, are wound together to form a high-frequency cable and then connected to the traction machine. As the traction machine continuously pulls the high-frequency cable, the wrapping film will be guided by the multiple wrapping grooves 7 that are gradually wrapped around the corresponding core wire holes 6 to wrap around the core wire, forming a core wire wrapped with wrapping film. After the core wire wrapped with wrapping film is output from the outlet head 3, the wrapping machine wraps the wrapping tape around the core wire wrapped with wrapping film, that is, the wrapping tape is wrapped around the wrapping film after wrapping, so that the wrapping film can be firmly wrapped around the core wire. When a high-frequency cable has a single or double ground wire, the ground wire passes sequentially through the ground wire holes 8 of multiple longitudinal wrapping molds 4 and the ground wire holes 8 of the outlet head 3. The ground wire holes 8 not only allow the ground wire to pass through but also guide and limit its movement, improving the positional accuracy and stability of the ground wire. After the ground wire is output from the ground wire holes 8 of the outlet head 3, the wrapping machine winds the ground wire and the core wire wrapped with the wrapping film together to form a high-frequency cable with a ground wire. This invention features ground wire holes 8 for the ground wire to pass through, resulting in high positional accuracy and good movement stability, enabling the production of high-frequency cables with ground wires.

[0023] Specifically, the support rod 2 has one end with the wire outlet 3 extending out of the mounting base 1, making the support rod 2 cantilevered. Therefore, when this utility model is used on the machine in a cantilevered manner, it is beneficial for the operator to better understand the angle changes and state of the wrapping film wrapped around the core wire through multiple longitudinal wrapping molds 4.

[0024] In this embodiment, all longitudinal wrapping molds 4 except the first and last two longitudinal wrapping molds 4 are provided with first opening slots 9 on both sides, and one first opening slot 9 is connected to a ground wire hole 8 of the longitudinal wrapping mold 4. In this structural design, among the multiple longitudinal wrapping molds 4, the ground wire holes 8 on the first and last longitudinal wrapping molds 4 are closed holes, while the ground wire holes 8 on the multiple middle longitudinal wrapping molds 4 are side-opening holes. When threading the ground wire, the ground wire is first threaded through the ground wire holes 8 of the first and last longitudinal wrapping molds 4, and then the ground wire is inserted from the first opening mold into the ground wire hole 8 on the middle longitudinal wrapping mold 4. This not only ensures the positional accuracy and movement stability of the ground wire, but also facilitates the threading of the ground wire.

[0025] In this embodiment, a limiting step 10 is provided on the bottom wall of the first opening groove 9 near the opening. After the ground wire is inserted into the corresponding ground wire hole 8 from the first opening groove 9, the limiting step 10 blocks and limits the ground wire to prevent the ground wire from moving out of the ground wire hole 8 from the first opening groove 9.

[0026] In this embodiment, a second opening groove 11 is provided on both sides of the outlet head 3, and one second opening groove 11 is connected to a ground wire hole 8 of the outlet head 3. After the ground wire passes through the ground wire holes 8 of multiple longitudinal molds, the ground wire is inserted into the outlet hole 5 from the second opening groove 11, so that the ground wire can pass through the outlet hole 5 of the outlet head 3.

[0027] In this embodiment, the longitudinal wrapping mold 4 is detachably connected to the support rod 2. This structural design not only facilitates the disassembly, assembly, and maintenance of the longitudinal mold and the support rod 2, but also allows for adjustment of the position of the longitudinal mold on the support rod 2, thereby adjusting the distance between two adjacent longitudinal wrapping molds 4 to adjust the forming angle of the wrapping film wrapped around the core wire.

[0028] In this embodiment, a first slider 12 is provided on the bottom surface of the longitudinal mold, and a groove 13 is recessed on the top surface of the support rod 2. The first slider 12 is slidably connected to the groove 13. When assembling and disassembling the longitudinal mold and the support rod 2, the first slider 12 of the longitudinal mold and the groove 13 of the support rod 2 slide together, which improves the convenience and stability of assembling and disassembling the longitudinal mold.

[0029] In this embodiment, the lead wire 3 is detachably connected to the support rod 2. This structural design not only facilitates the disassembly, assembly, and maintenance of the lead wire 3 and the support rod 2, but also allows for adjustment of the position of the lead wire 3 on the support rod 2, thereby adjusting the distance between the lead wire 3 and the adjacent longitudinal wrapping mold 4.

[0030] In this embodiment, a second slider 14 is provided on the bottom surface of the cable outlet 3, and the second slider 14 is slidably connected to the slide groove 13. When disassembling and assembling the cable outlet 3 and the support rod 2, the second slider 14 of the cable outlet 3 slides in conjunction with the slide groove 13 of the support rod 2, which improves the convenience and stability of disassembling and assembling the cable outlet 3.

[0031] In this embodiment, the bottom wall of the slide 13 is provided with multiple locking holes 15, which are equally spaced along the length of the slide 13. Each locking hole 15 is detachably connected to a locking fastener, which is used to lock the longitudinal mold 4 and the lead wire 3 onto the support rod 2. Specifically, the locking hole 15 is a threaded hole, and the locking fastener is a locking bolt. The locking bolt is threaded into the threaded hole, and the end face of the locking bolt abuts against the bottom surface of the longitudinal mold 4 or the lead wire 3. This structural design not only facilitates the disassembly, assembly, and position adjustment of the longitudinal mold and the lead wire 3, but also ensures a secure assembly of the longitudinal mold, the lead wire 3, and the support rod 2.

[0032] In this embodiment, a mounting ring 17 is provided at the end of the mounting base 1 away from the cable outlet 3. The top surface of the mounting base 1 is recessed with an arc-shaped guide groove 18, and the bottom surface of the support rod 2 is provided with an arc-shaped surface 19 that conforms to the arc-shaped guide groove 18. This structural design facilitates the assembly of the mounting base 1 and the support rod 2, resulting in a compact structure. Furthermore, the sliding fit between the arc-shaped guide groove 18 and the arc-shaped surface 19 facilitates the adjustment of the relative position between the mounting base 1 and the support rod 2. The mounting ring 17 facilitates the installation of this invention on a machine.

[0033] Specifically, the support rod 2 passes through the mounting ring 17, and the bottom surface of the mounting base 1 has a slot 20 communicating with the arc guide groove 18. The locking member passes through the slot 20 and is detachably connected to the locking hole 15. The locking member is used to lock the mounting base 1 and the support rod 2 together, and the locking member is a locking bolt that is threadedly connected to the locking hole 15. This structural design not only makes the connection between the support rod 2 and the mounting base 1 firm, but also facilitates the adjustment of the relative position of the support rod 2 and the mounting base 1.

[0034] Specifically, the multiple vertical wrapping molds 4 are respectively a first vertical wrapping mold, a second vertical wrapping mold, a third vertical wrapping mold, and a fourth vertical wrapping mold. The cross-sectional shape of the wrapping groove 7 of the first vertical wrapping mold and the wrapping groove 7 of the second vertical wrapping mold are both V-shaped or U-shaped. The opening of the wrapping groove 7 of the first vertical wrapping mold is larger than the opening of the wrapping groove 7 of the second vertical wrapping mold. The core wire hole 6 of the first vertical wrapping mold is located inside the wrapping groove 7 of the first vertical wrapping mold, the core wire hole 6 of the second vertical wrapping mold is located inside the wrapping groove 7 of the second vertical wrapping mold, and the wrapping groove 7 of the third vertical wrapping mold is V-shaped or U-shaped. The third longitudinal wrapping mold has a core wire hole 6 that is either shaped like the letter "a" or spiral, located within the loop of the wrapping groove 7 and connected to it. The fourth longitudinal wrapping mold has an arc-shaped wrapping groove 7 that is connected to the core wire hole 6. By setting wrapping grooves 7 of different shapes on different longitudinal wrapping molds 4, as the wrapping film and core wire move, guided by the sequential winding of multiple wrapping grooves 7, the wrapping grooves 7 can not only position the wrapping film and ensure the stability of its movement, but also automatically wind the wrapping film around the core wire. This structure is simple, has low usage and manufacturing costs, and provides good wrapping stability, high efficiency, and high quality.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
