Description

Technical Field

[0001] The present application belongs to the technical field of manufacturing communication line tape molds, and specifically relates to a high-speed data communication line tape assembly mold. Background Art

[0002] PCIe high-speed cables, SAS high-speed cables, 112G backplane high-speed cables, external (Q)SFP+ high-speed cables, (Q)SFP28 high-speed cables, (Q)SFP56 high-speed cables, 400GQSFP high-speed cables, and 800GQSFP high-speed cables all require cable wrapping. This process involves wrapping the cable's outer surface with a polyester tape or other covering material. However, due to the cable's flat cross-section, it's prone to shaking at the opening of a typical mold, increasing the risk of surface damage. This can lead to high-frequency spikes in the cable's attenuation performance after wrapping. Utility Model Content

[0003] The purpose of this application is mainly to address the shortcomings of the existing technology. By designing the length line of the geometric center of the cross section of the channel as the projection of the contact surface between the left mold and the right mold on the cross section of the channel, a high-speed data communication line tape wrapping splicing mold is designed. When the tape on the high-speed data communication line passes through the mold, the contact surface between the left mold and the right mold passes between the two ends of the thickness line of the high-speed data communication line, thereby avoiding the problem that the contact surface between the left mold and the right mold cuts (scratches) the upper and lower surfaces of the high-speed data communication line when the mold is opened and closed in the process of the high-speed data communication line coming out of the splicing mold, thereby affecting the performance of the communication line.

[0004] In order to achieve the above objectives, the technical solution adopted in this application is:

A channel is axially penetrated on the split mold formed by the left mold and the right mold. The cross-section of the channel is rectangular. The length line passing through the geometric center of the rectangle is the projection of the contact surface between the left mold and the right mold on the cross-section of the channel.

[0006] Preferably, the combined mold is a coaxial frustum and cylinder, the central axis of the cylinder and the central axis of the frustum are both on the contact surface between the left mold and the right mold, and one end of the cylinder is connected to the end of the frustum with a relatively larger outer diameter.

[0007] Preferably, through holes are provided on both the left mold and the right mold, the axes of the through holes are perpendicular to the abutting surfaces between the left mold and the right mold, and the left mold and the right mold are locked together by bolts passing through the through holes.

[0008] Preferably, the split mold is made of P20 steel.

[0009] Preferably, an expansion channel is provided on the cylinder, the inner diameter of the expansion channel is larger than the inner diameter of the channel, the end of the expansion channel facing away from the frustum extends outside the cylinder, and the end of the expansion channel facing the frustum is connected to the channel.

[0011] Preferably, the outer diameter of the cylinder is smaller than the outer diameter of the end of the frustum with a relatively larger outer diameter.

[0020] like Figure 1-2As shown, a high-speed data communication line wrapping split mold includes a left mold 1 and a right mold 2 that cooperate with each other. The left mold 1 and the right mold 2 are symmetrically arranged. The split mold formed by the cooperation of the left mold 1 and the right mold 2 has an axial channel 3 passing through it. The cross-section of the channel 3 is a rectangle. The length line passing through the geometric center of the rectangle is the projection of the contact surface between the left mold 1 and the right mold 2 on the cross-section of the channel 3.

[0021] In this embodiment, when in use, the left mold 1 and the right mold 2 are combined to form a split mold, and then the communication line is passed through the channel 3. A device for conveying the communication line (a take-up reel, etc.) is set outside the split mold, and polyester is injected into the split mold so that after the communication line passes through the channel 3 of the split mold, it is covered with polyester on the surface of the communication line, and the cross-section of the polyester attached to the surface of the communication line is consistent with the shape and size of the inner cross-section of the channel 3, so that the polyester protects the communication line. Since the overlapping surface of the left mold 1 and the right mold 2 after the mold is closed (the contact surface between the left mold 1 and the right mold 2) is projected on the cross-section of the channel 3 as a straight line L, and the straight line L is the length line of the rectangular cross-section of the channel 3, and the straight line L passes through the geometric center of the cross-section of the channel 3, therefore, during the process of opening or closing the left mold 1 and the right mold 2, the upper and lower surfaces of the surface of the communication line will not be scraped, but only the corrugated surface of the communication line will be scraped. Since the corrugated surface of the communication line is relatively small in area, it will not affect the performance of the communication line.

[0022] As a preferred embodiment, the combined mold is a coaxial truncated cone 4 and a cylindrical body 5, the central axis of the cylindrical body 5 and the central axis of the truncated cone 4 are both on the contact surface between the left mold 1 and the right mold 2, and one end of the cylindrical body 5 is connected to the end of the truncated cone 4 with a relatively large outer diameter.

[0023] After such arrangement, the cylinder 5 is equivalent to a mounting portion, thereby facilitating the installation of the split mold on the machine so that the polyester is wrapped around the surface of the communication line.

[0024] As a preferred embodiment, a through hole 6 is provided on each of the left mold 1 and the right mold 2. The axis of the through hole 6 is perpendicular to the contact surface between the left mold 1 and the right mold 2. The left mold 1 and the right mold 2 are locked together by bolts passing through the through holes 6. In this way, the provision of the through holes 6 and the bolts facilitates the merging of the left mold 1 and the right mold 2.

[0025] As a preferred embodiment, the split mold is made of P20 steel.

[0026] As a preferred embodiment, an expansion channel 7 is provided on the cylindrical body 5. The inner diameter of the expansion channel 7 is larger than the inner diameter of the channel 3. The end of the expansion channel 7 facing away from the frustum 4 extends outside the cylindrical body 5, and the end of the expansion channel 7 facing the frustum 4 is connected to the channel 3. This arrangement facilitates the injection of polyester into the channel 3 so that the polyester adheres to the communication line.

[0027] As a preferred embodiment, an expansion hole 8 is coaxially provided on the outer surface of each of the left mold 1 and the right mold 2 at the location of the through hole 6, and the inner diameter of the expansion hole 8 is larger than the inner diameter of the through hole 6. This arrangement of the expansion hole 8 ensures that after the left mold 1 and the right mold 2 are locked together, the volume of the split mold will not be increased due to the use of bolts.

[0028] As a preferred embodiment, the outer diameter of the cylinder 5 is smaller than the outer diameter of the end of the frustum 4 with a relatively larger outer diameter.
