Abstract
Description
Technical Field
[0001] The present application relates to the field of cable preparation, and in particular to a tape positioning mold. Background Art
[0002] High-speed line, also known as high-speed data line, is a cable used for high-speed data transmission.
[0003] High-speed cables generally have a two-core, two-ground structure, with the two ground wires located on both sides of the core wire to facilitate cutting and peeling of the overall component, which is then welded during the electrical connection process.
[0004] Therefore, it is very important whether the ground wire is centered above and below. If it is not centered, the ground wire will be cut during the cutting and peeling process. Cutting and peeling means removing insulation and shielding by cutting.
[0005] like Figure 1 As shown, in an ideal state, the high-speed line 100 has two ground wires 120 located on both sides of the two core wires 110 and centered relative to the upper and lower symmetry lines 130. That is, in an ideal state, the axes of the two ground wires 120 and the axes of the two core wires 110 are located on the same straight line, which is the upper and lower symmetry line 130. This can reduce signal attenuation and ensure signal transmission effect.
[0006] However, in actual production, absolute centering does not exist, and it is inevitable that the ground line 120 deviates from the upper and lower symmetry lines 130 at the micro level or even at the macro level, such as Figure 2 and Figure 3 As shown, the two core wires 110 are respectively the first core wire 111 and the second core wire 112, and the two ground wires 120 are respectively the first ground wire 121 and the second ground wire 122, which are respectively located on both sides of the first core wire 111 and the second core wire 112 as a whole, wherein the second ground wire 122 has a variable deviation angle A relative to the upper and lower symmetry lines 130.
[0007] In order to solve this problem, the traditional production method uses a molding die with ground wire holes, which are set on the left and right sides to fix the ground wire position so that the ground wire will not deviate too much during the outer layer wrapping process. Figure 4 and Figure 5 As shown, the molding die 200 is provided with a center hole 210 and a circular ground wire hole 220 . During the molding process through the molding die 200 , the core wire 110 and its insulation structure pass through the center hole 210 , and the ground wire 120 passes through the ground wire hole 220 .
[0008] In the specific process, since the ground wire 120 is thinner than the core wire 110, the ground wire hole 220 is required to be made thinner. However, the molding die 200 is prone to blockage due to accumulation of tin ash and other dirt during operation. That is, the molding die 200 is prone to blockage due to contact with tin ash and other dirt during operation. Therefore, the ground wire hole 220 must have a larger passing diameter than the ground wire 120 to avoid blockage.
[0009] However, Figure 6 As shown, when the ground wire hole 220 is too large, it is easy to cause the ground wire 120 to be deviated by the wrapping tape during the wrapping process, so the problem of the ground wire not being centered still exists. Summary of the invention
[0010] Based on this, it is necessary to provide a wrapping tape positioning mold.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0055] The present application discloses a tape wrapping positioning mold, which includes some or all of the technical features of the following embodiments; that is, the tape wrapping positioning mold includes some or all of the following structures. In one embodiment of the present application, a tape wrapping positioning mold includes a main body, and the tape wrapping positioning mold is provided with a center hole and a ground wire groove on the main body; the ground wire groove is spaced apart from the center hole, and in the cross section of the extension direction of the main body, the ground wire groove passes through the outer edge of the main body; the ground wire groove is configured to fix the position of the ground wire to position the ground wire in the tape wrapping state. The above-mentioned tape wrapping positioning mold uses a flat ground wire groove to replace the conventional circular ground wire hole, which perfectly solves the contradiction that a small ground wire hole is easy to be blocked and a large ground wire hole is inevitably inaccurately positioned. It can be made into a relatively small ground wire groove that matches the size of the ground wire, thereby ensuring the quality of the high-speed data cable produced, good consistency, and is conducive to the discharge of tin ash and other contaminants to avoid blockage. The following is combined with Figures 1 to 13 , the strap positioning mold is described in detail.
[0056] In one embodiment of the present application, a wrapping tape positioning mold 300 is as follows: Figure 7 As shown, it includes a body 330, and the wrapping tape positioning mold 300 is provided with a center hole 210 and a ground wire groove in the body 330; Figure 5 Compared with the traditional molding mold 200 shown in the figure, the tape positioning mold 300 described in this embodiment is also provided with a center hole 210 to fix the position of the core wire 110, which can also be understood as fixing the position of the semi-finished product with the core wire 110 and its insulation layer or other structures. However, compared with the circular ground wire hole 220 of the traditional molding mold 200, the tape positioning mold 300 described in this embodiment adopts a flat ground wire groove design. The flatness is relative to the circular ground wire hole 220, which is specifically explained as follows.
[0057] like Figure 7 As shown, the ground wire groove is spaced apart from the center hole 210, and the cross section in the extension direction 340 of the main body 330 is as shown in FIG. Figure 8 As shown, the ground wire groove passes through the outer edge 337 of the body 330; the ground wire groove is configured to fix the position of the ground wire 120 so as to position the ground wire 120 in the wrapped state. That is, relative to the cross section of the extension direction 340, the ground wire groove runs from the position close to the center hole 210 to the outside of the body 330, so that for the body 330, each ground wire groove has a sewage outlet at both ends and a sewage outlet on one side, relative to Figure 5 The traditional ground wire hole 220 shown greatly improves the sewage discharge capacity.
[0058] As an example, the traditional ground wire hole is changed to a horizontal ground wire groove. Figure 5 and Figure 8 It can be seen that with such a structural design, tin ash or other dirt that enters the ground wire groove can be discharged from the outer edge 337 of the main body 330 along the ground wire groove, so it is not easy to get clogged. In contrast, the ground wire hole 220 of the traditional molding mold 200 can only be discharged from both ends, that is, the dirt is discharged from both ends along the extension direction 340 of the main body 330, so it is easy to get clogged. With such a structural design, a flat ground wire groove is used to replace the conventional circular ground wire hole, which perfectly solves the contradiction that a small ground wire hole is easy to get clogged and a large ground wire hole is inevitably inaccurately positioned. That is, for the traditional molding mold, if the design of the ground wire hole accurately matches the ground wire 120, there is a problem that the small ground wire hole is easy to get clogged. If the design of a large ground wire hole to facilitate the discharge of dirt is used, there is a problem of inaccurate positioning. This contradiction makes it impossible to make a mold based on the traditional design. Figure 1 The ideal high-speed line shown in the figure; therefore, the traditional design scheme based on the circular hole is a dilemma, that is, based on the conventional circular ground wire hole, dirt can only be discharged from the two ports, one in front and one in the back, which leads to the inability to solve the dilemma of blockage and positioning from the root. The relevant embodiments of the present application can be made into a relatively small ground wire groove to match the size of the ground wire, thereby ensuring the quality of the manufactured high-speed data line with good consistency, and it is also conducive to the discharge of tin ash and other dirt to avoid blockage. The tin ash is discharged from both sides during the vibration process of the wrapping, so that the drainage capacity is not limited by the two ends. Therefore, the problem of tin ash falling from the ground wire blocking the hole when the hole is small is almost perfectly solved. Moreover, when the gap of the ground wire groove is smaller, the position of the ground wire can be more accurately controlled. The ideal ground wire groove can perfectly match the shape of the ground wire 120, so that a better ground wire angle can be maintained during the wrapping process, and then a high-speed line with a nearly ideal symmetrical state can be made. This is impossible to achieve with traditional designs.
[0059] In order to facilitate the discharge of dirt and convenient wrapping, in one embodiment, as Figure 7As shown, in the extension direction 340 of the body 330, the passing area of the ground wire groove is gradually increased or gradually reduced; or, in other embodiments, the passing area of the end of the ground wire groove close to the center hole 210 is smaller than the passing area of the end of the ground wire groove close to the outer edge 337. Exemplarily, the end of the ground wire groove close to the center hole 210 is used as the assembly end, the shape of the assembly end is the same as the shape of the ground wire 120, and the assembly end and the ground wire 120 are clearance-matched, that is, loosely matched; in combination with the embodiment of the reverse pre-bias angle B set according to the wrapping direction 400 of the wrapping positioning mold 300, a more precise ground wire 120 position control effect is achieved. Such a structural design, on the one hand, is conducive to facilitating the taping treatment of the ground wire 120 in the taping positioning mold 300 during the taping process, and on the other hand, is conducive to discharging tin ash or other contaminants on the outer side of the extension direction 340 of the main body 330. On the other hand, it is conducive to strictly limiting the position of the ground wire 120 without affecting the taping process. Therefore, a better ground wire angle can be maintained during the taping process, thereby making a high-speed line in a nearly ideal symmetrical state, which is impossible to achieve with traditional designs.
[0060] In one of the embodiments, the number of the ground wire troughs is a pair, and the pair of ground wire troughs are symmetrically arranged. Exemplarily, the pair of ground wire troughs are axially symmetrically arranged or rotationally symmetrically arranged. As an example, the pair of ground wire troughs are rotationally symmetrically arranged, that is, after any of the ground wire troughs rotates a certain angle along a certain point, the axes of the two ground wire troughs coincide with each other; if they coincide after rotating 180 degrees, then the pair of ground wire troughs are centrally symmetrically arranged. In one of the embodiments, the ground wire trough has a pair of parallel trough surfaces; as an example, Figure 8 As shown, a pair of ground wire grooves are respectively a first ground wire groove 310 and a second ground wire groove 320, and any ground wire groove has a pair of parallel groove surfaces. As shown in the figure, the second ground wire groove 320 includes a first groove surface 311 and a second groove surface 312, and the first groove surface 311 is arranged parallel to the second groove surface 312. Such a structural design is conducive to limiting the position of the ground wire 120 in the first ground wire groove 310 and the second ground wire groove 320, thereby ensuring the accuracy of the position of the ground wire 120 in the high-speed line 100.
[0061] In one embodiment, if Figure 8 and Fig. 9As shown, the ground wire groove includes a first ground wire groove 310 and a second ground wire groove 320. The extension direction of the first ground wire groove 310 and the extension direction of the second ground wire groove 320 have a reverse pre-bias angle B. Since the tape has a certain deflection force on the ground wire 120 in the tape wrapping process, causing the position of the ground wire 120 to shift, the reverse pre-bias angle B can be designed to offset the position of the ground wire 120, thereby facilitating the high-speed line 100 with an accurate position of the ground wire 120, thereby ensuring that the signal transmission of the high-speed line 100 achieves the designed effect. As an example, the angle of the reverse pre-bias angle B is set according to the tape wrapping direction 400 of the tape wrapping positioning mold 300. With such a structural design, the angle of the reverse pre-bias angle B can be positive or negative. The tape wrapping direction 400 is clockwise, and the angle of the reverse pre-bias angle B is set in the opposite direction, so it is a negative value, which can also be understood as a large angle exceeding 180 degrees, for example, negative 5 degrees is 355 degrees. The wrapping direction 400 is counterclockwise, and the reverse pre-bias angle B is a positive value, such as 4 degrees, 5 degrees, 5.5 degrees, 5.8 degrees, 6 degrees, etc. Those skilled in the art will appreciate that the specific values of the above angles are only examples, and are not strict limitations on the reverse pre-bias angle B described in the embodiments of the present application.
[0062] In each embodiment, the ground wire slot can be pre-deflected by a certain angle in the reverse direction according to the wrapping direction 400. For the embodiment with the reverse pre-deflection angle B, in one embodiment, as Fig. 9 As shown, the angle of the reverse pre-bias angle B is set according to the wrapping direction 400 of the wrapping positioning mold 300, that is, according to the angle at which the ground wire 120 is driven to deflect during wrapping. Fig. 9 In the direction shown, if the angle of the right ground wire is offset downward by 5° when wrapped with a non-offset mold, then it is only necessary to offset the right seam of the wrapping tape positioning mold 300, i.e., the second ground wire groove 320, upward by 5° to ensure that the right ground wire 120 is in the middle position after wrapping, and the same is true for the left side. In other embodiments, the angle of the reverse pre-bias angle B is also set according to the wrapping speed of the wrapping tape positioning mold 300, that is, the angle of the reverse pre-bias angle B is set according to the wrapping direction 400 and the wrapping speed of the wrapping tape positioning mold 300. The rest of the embodiments are similar and will not be described in detail.
[0063] In one embodiment, if Fig. 9 As shown, in the cross section of the body 330, the center hole 210 has an upper and lower symmetry line 130; the upper and lower symmetry line 130 can also be combined Figure 2As shown, the center hole 210 and the two core wires 110 passing through the center hole 210 are symmetrical in the upper and lower directions shown in the figure. In this embodiment, the ground wire groove includes a first ground wire groove 310 and a second ground wire groove 320, and at least one of the extension direction of the first ground wire groove 310 and the extension direction of the second ground wire groove 320 has a reverse pre-bias angle B relative to the upper and lower symmetry line 130. Different from the previous embodiment, in this embodiment, at least one of the extension direction of the first ground wire groove 310 and the extension direction of the second ground wire groove 320 has a reverse pre-bias angle B relative to the upper and lower symmetry line 130, and the upper and lower symmetry line 130 is used as a reference system; in contrast, in the previous embodiment, the extension direction of the first ground wire groove 310 and the extension direction of the second ground wire groove 320 have a reverse pre-bias angle B, and the upper and lower symmetry line 130 is not used as a reference system.
[0064] In one embodiment, the first ground wire groove 310 is symmetrically arranged with respect to the upper and lower symmetry lines 130, and the second ground wire groove 320 has the reverse pre-bias angle B with respect to the upper and lower symmetry lines 130; or, in other embodiments, the first ground wire groove 310 and the second ground wire groove 320 both have the reverse pre-bias angle B with respect to the upper and lower symmetry lines 130; it can be understood that the angle of the reverse pre-bias angle B in this embodiment is generally half of the angle of the reverse pre-bias angle B in the previous embodiment.
[0065] In one embodiment, the body 330 may be integrally formed, such as Figures 7 to 9 In other embodiments, the main body 330 may also be provided in separate parts, as shown in the following examples.

In this embodiment, the tape positioning mold 300 or the body 330 further includes a mold base 334, and the first threading module 331, the second threading module 332 and the core 333 are all positioned and disposed on the mold base 334.

In order to fix these components to each other, as an example, the tape positioning mold 300 also includes a first adjustment member 301, a second adjustment member 302, a third adjustment member 303, a fourth adjustment member 304, a fifth adjustment member 305 and a sixth adjustment member 306; the mold base 334 is provided with a chamber 336, and the first threading module 331, the second threading module 332 and the mold core 333 are all arranged in the chamber 336, the first adjustment member 301, the second adjustment member 302 and the third adjustment member 303 jointly fix the first threading module 331 to the mold core 333 and the mold base 334, and the relative positions of the first threading module 331 and the mold core 333, and the The relative position of the first threading module 331 and the mold base 334 is adjusted by the first adjusting member 301, the second adjusting member 302 and the third adjusting member 303; that is, the position of the first threading module 331 is fixed relative to the mold core 333 and the mold base 334 under the joint action of the first adjusting member 301, the second adjusting member 302 and the third adjusting member 303, and when necessary, it can be fine-tuned by adjusting at least one of the first adjusting member 301, the second adjusting member 302 and the third adjusting member 303 to adapt to the wrapping speed of the wrapping positioning mold 300, so that the position of the ground wire 120 is more accurate, and it is as good as possible.

Similarly, the position of the second threading module 332 is fixed relative to the mold core 333 and the mold base 334 under the joint action of the fourth adjusting member 304, the fifth adjusting member 305 and the sixth adjusting member 306, and on the other hand, when necessary, it can be fine-tuned by adjusting at least one of the fourth adjusting member 304, the fifth adjusting member 305 and the sixth adjusting member 306 to adapt to the tape wrapping rate of the tape wrapping positioning mold 300, so that the position of the ground wire 120 is more accurate, and it is as close as possible to the following.

[0069] In the above embodiment, the positions of the ground wire grooves on the left and right sides can be made to be fine-tuned up and down the upper and lower symmetry lines 130. In specific applications, such as Fig.10 As shown, inside the wrapping tape positioning mold 300 or the main body 330, a certain space is hollowed out above and below the ground wire groove to form an avoidance position 338, so that the first threading module 331 and the second threading module 332 can move up and down in the avoidance position 338 inside the mold according to the direction shown in the figure. The first threading module 331 and the second threading module 332 can also be understood as separate components with walls, and the first ground wire groove 310 and the second ground wire groove 320 are opened inside. In this way, the first threading module 331 and the second threading module 332 can be moved to the desired position or angle inside the mold and then locked with fixing screws around the top, bottom, left and right.
[0070] In each embodiment, the adjusting member, including the first adjusting member 301, the second adjusting member 302, the third adjusting member 303, the fourth adjusting member 304, the fifth adjusting member 305 and the sixth adjusting member 306, can be a stud or a bolt, or a plug-in abutting structure, so as to fine-tune the positions of the first grounding trough 310 and the second grounding trough 320 to a certain extent. As an example, a stud is used to connect the mold core 333 and the mold base 334 in a threaded manner, and abuts against the first threading module 331 and / or the second threading module 332, so as to fix the first threading module 331 with the mold core 333 and the mold base 334, and fix the second threading module 332 with the mold core 333 and the mold base 334.
[0071] In other embodiments, the first threading module 331 and the second threading module 332 may also be integrally arranged. In one embodiment, the tape positioning mold 300 further includes an adjusting member. The first threading module 331 and the second threading module 332 are integrally arranged and rotatably arranged outside the mold core 333. The adjusting member fixes the first threading module 331 and the second threading module 332 to the mold core 333, and the relative positions of the first threading module 331 and the second threading module 332 to the mold core 333 are adjusted by the adjusting member. As an example, Fig.12 and Fig.13 As shown, the first threading module 331 and the second threading module 332 are integrated as a whole, and the whole is rotatably arranged outside the mold core 333. In this embodiment, the mold core 333 has a columnar shape, such as a cylindrical shape, and the whole is surrounded outside the mold core 333. The third adjustment member 303 and the sixth adjustment member 306 fix the whole outside the mold core 333.
[0072] As an example, Fig.10and Fig.11 As shown, the other structures of the wrapping tape positioning mold 300 or its body 330 except the first threading module 331 and the second threading module 332 can be made into an integral structure, and the first threading module 331 and the second threading module 332 are movably arranged inside the wrapping tape positioning mold 300; Fig.12 and Fig.13 As shown, the core 333 with the center hole 210 is used as the first separate component, the first threading module 331 and the second threading module 332 are integrally arranged as the second separate component, and the second separate component can rotate around the first separate component, so as to achieve the function of adjusting the angle of the ground wire groove in real time. Alternatively, the first threading module 331 and the second threading module 332 can be separately arranged as separate components, so as to achieve independent adjustment of the ground wires on both sides without affecting each other.
[0073] Such a structural design, in some embodiments, uses a flat ground wire trough to replace the conventional circular ground wire hole, which perfectly solves the conflict between the small ground wire hole blocking mold and the large hole inaccurate positioning, so that both can be taken into account; in some embodiments, the ground wire trough is pre-deviated in the reverse direction according to the wrapping situation to offset the ground wire offset effect caused by the wrapping stress; in some embodiments, by using a split wrapping positioning mold, the ground wire trough position of the mold can be fine-tuned online, which greatly reduces the difficulty for the operator to adjust the ground wire angle.
[0074] It should be noted that other embodiments of the present application also include a wrapping tape positioning mold that can be implemented by combining the technical features in the above embodiments.
[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
