Description

Technical Field

[0001] This utility model relates to the technical field of communication cables, and in particular to an isolation cross frame for preventing twisted wire pairs from flipping. Background Technology

[0002] Communication cables are the connecting wires for network equipment. Twisted-pair cables are currently the most widely used type of communication cable. Also known as twisted-pair cables, they consist of four pairs of copper conductors twisted together with insulating material, all encased in an insulated cable sheath. Twisting two insulated copper conductors together at a certain density not only resists some external electromagnetic interference but also reduces mutual interference between the twisted pairs. Because the interference signal acts uniformly on both twisted conductors (this interference signal is called a common-mode signal), it can be eliminated in the differential circuit receiving the signal, thus extracting the useful signal and effectively reducing the degree of signal interference.

[0003] Currently, in stranded cables, a cross-shaped frame is used inside to separate the four pairs of conductors. The four pairs of conductors are embedded in four sections of this frame, thus isolating them. However, during installation, the cross-shaped frame and the bushing are prone to relative rotation and flipping, causing the stranded pairs within the frame to twist and separate. This alters the impedance of the stranded pairs, affecting information transmission. Summary of the Invention

[0004] In order to prevent relative rotation and flipping between the cross frame and the sleeve, this utility model provides an isolation cross frame to prevent the twisted wire pair from flipping, addressing the problems of the prior art.

[0005] This utility model provides an isolation cross frame for preventing twisted wire pairs from flipping, which adopts the following technical solution:

[0006] An isolation cross frame for preventing twisted wire pairs from flipping includes multiple isolation plates. The sides of the multiple isolation plates intersect at the same point, and the multiple isolation plates intersect to form a frame. The area between two adjacent isolation plates is a wire feeding area. A blocking plate is provided on the other side of the isolation plates, and a protrusion is provided on the surface of the blocking plate facing away from the wire feeding area.

[0007] Preferably, the protrusion is located on the extension line of the side of the separator.

[0008] Preferably, the isolation sheet is configured as four pieces, and the skeleton is arranged in a cross shape.

[0009] Preferably, the skeleton is made of ABS plastic.

[0010] Preferably, the blocking sheet and the isolating sheet are arranged perpendicular to each other.

[0011] A communication cable includes an isolation cross frame for preventing twisted wire pairs from flipping, as described above. Twisted wire pairs are provided in the cable laying area, and an insulating sleeve is provided on the outer casing of the frame.

[0012] Preferably, the tab is embedded in the inner wall of the sleeve.

[0013] Preferably, a shielding layer is provided between the skeleton and the insulating sleeve, and one side of the protrusion abuts against the shielding layer.

[0014] In summary, this utility model includes at least one of the following beneficial technical effects of the anti-twisting stranded wire isolation cross skeleton:

[0015] The tabs increase the pressure between the skeleton and the insulating sleeve, thereby increasing the friction between them. During construction, the cross skeleton and the insulating sleeve inside the communication cable are less likely to rotate or flip due to the greater friction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Example 1, Implementation of this utility model, discloses an isolation cross frame for preventing twisted wire pairs from flipping, such as... Figure 1 As shown, the system includes multiple isolation plates 1. In this embodiment, the number of isolation plates 1 is preferably four. The four isolation plates 1 intersect at one side to form a frame, and the central axis of the frame is the intersection of the four isolation plates 1. The four isolation plates 1 are integrally molded, and the frame is made of ABS plastic, which provides good fire resistance. Furthermore, adjacent isolation plates 1 are arranged perpendicularly to each other, making the frame cross-shaped, thus providing better structural strength.

[0023] In addition, the area between two adjacent isolation plates 1 is the cable laying area 2. After placing the stranded wire pairs in the cable laying area, an insulating sleeve is installed on the frame to form a communication cable.

[0024] Additionally, a blocking plate 3 is integrally formed on the side of the isolation plate 1 away from the central axis of the skeleton. The blocking plate 3 and the isolation plate 1 are arranged perpendicularly to each other. Blocking plates 3 are provided on both opposite surfaces of the isolation plate 1. A protrusion 4 is integrally formed on the side of the blocking plate 3 away from the central axis of the skeleton. The protrusion 4 is located on the extension line from the central axis of the skeleton along the isolation plate 1 outward. This allows the isolation plate 1 to better support the protrusion 4. The blocking plate 3 is partially attached to the inner wall of the insulating sleeve, and the protrusion 4 abuts against the inner wall of the insulating sleeve. The protrusion 4 increases the pressure between the skeleton and the insulating sleeve, thereby increasing the friction between the skeleton and the insulating sleeve. Thus, during construction, the cross skeleton and the insulating sleeve inside the communication cable are less likely to rotate or flip due to the greater friction. Meanwhile, in the skeleton, the combined length of the isolation plate 1 and the protrusion 4 on opposite sides of the skeleton is 11.1 mm. The thickness of the isolation plate 1, the protrusion 4 and the blocking plate 3 is 0.3 mm. The width of the protrusion 4 is 1 mm. The total width of the blocking plates 3 on both sides of the isolation plate 1 is 3.1 mm.

[0025] Furthermore, during the production of communication cables, when the insulating sleeve is freshly manufactured, it is still in a softened state. At this time, the cross-shaped frame is assembled with the insulating sleeve, so that the protrusion 4 is embedded in the inner wall of the insulating sleeve. This makes the connection between the cross-shaped frame and the insulating sleeve tighter and less prone to rotation or flipping. In addition, when a metal shielding layer is provided between the cross-shaped frame and the insulating sleeve, one side of the protrusion 4 abuts against the shielding layer, and the protrusion 4 lifts up the shielding layer and the insulating sleeve, thereby increasing the friction between the frame, the shielding layer, and the insulating sleeve. Thus, in communication cables with a shielding layer, the cross-shaped frame is less likely to rotate or flip during construction.

[0026] Example 2: The difference from Example 1 is that, referring to... Figure 2 The blocking plate 3 is arranged in an arc shape, and the center of the blocking plate 3 is located on the central axis of the skeleton.

[0027] Example 3: The difference from Example 2 is that, referring to... Figure 3 Only one side surface of the isolation plate 1 is provided with a blocking plate 3, which can be either flat or arc-shaped.
