Detailed Description

Generally, a cable of a Universal Serial Bus (USB) connector, which is standardized generally, is composed of a plurality of wires, an Inner Shield (Inner Shield), an Outer Shield (Outer Shield), an insulating sheath, wherein the insulating sheath is made of a rigid, flexible, rigid PVC casing, which is directly integrated into a single body, and cannot provide high flexibility, and the PVC appearance is poor in quality. The present invention provides a variety of cables that can solve the above problems.

Fig. 1 is a schematic diagram of an electronic device according to an embodiment of the utility model. Referring to fig. 1, the cable 100 of the present embodiment is applied to an electronic device 10, for example. In the present embodiment, the electronic device 10 is, for example, an input device (e.g., a mouse, a keyboard, a game pad, etc.), but in other embodiments, the electronic device 10 may be other peripheral devices, external power supply components, storage devices, or portable devices, and the type of the electronic device 10 is not limited thereto.

In the present embodiment, the electronic device 10 includes a cable 100, a connector 200 (for example, a USB2.0 interface), and a body 300 (for example, a mouse, a keyboard, or a joystick body). The cable 100 is connected between the body 300 and the connector 200.

Fig. 2 is a partially disassembled schematic view of the connector of fig. 1. Fig. 3 is a cross-sectional schematic view of the cable of fig. 1. Note that the connector 200 in fig. 2 omits the illustration of the insulating housing 220. In the present embodiment, the connector 200 includes a conductive housing 210 and a pin portion 230 disposed in the conductive housing 210. Specifically, the conductive housing 210 includes a first portion 211 and a second portion 212 that are engaged with each other. The pin part 230 includes a plurality of

pins

231, 232, 233, 234. Although fig. 2 illustrates the connector 200 with USB2.0 interface as an example, the utility model is not limited thereto, and other embodiments may also employ a connector with USB3.0 or 4.0 interface.

The cable 100 includes a plurality of conductors, a shield 150, and an overlapping protective layer 160. For example, the multiple wires of the cable of the USB2.0 interface are red wires: power supply positive electrode (VCC), green line: positive voltage data line (D +), white line: negative voltage data line (D-), black line: and (3) Ground (GND). In the present embodiment, the plurality of conductive lines are, for example, the power line 110, the ground line 120, the first differential signal line 130 and the second differential signal line 140 that are electrically insulated from each other. The conductive wires of the present embodiment respectively include cladding layers 111, 121, 131, and 141, wherein the cladding layers 111, 121, 131, and 141 are respectively integrally encapsulated or surrounded by an insulating material, for example, outside the power line 110, the ground line 120, the first differential signal line 130, and the second differential signal line 140, so as to electrically insulate the conductive wires from each other. One end of the power line 110, the ground line 120, the first differential signal line 130 and the second differential signal line 140 is connected to the

pins

231, 232, 233 and 234, and the other end is connected to a circuit board in the main body 300, so that the main body 300 is electrically connected to an information processing system (not shown) through the cable 100 and the connector 200. Here, the information processing system is, for example, a computer.

In the present embodiment, the shielding layer 150 covers the power line 110, the ground line 120, the first differential signal line 130 and the second differential signal line 140. The overlapping protection layer 160 encapsulates the shielding layer 150. The overlapping protection layer 160 includes a plurality of insulating materials, each of which is in the shape of, for example, a strip, a line, or a wire, and the strip, the line, or the wire insulating materials are interlaced with each other and have a void by repeating processes such as weaving, braiding, overlapping, etc., thereby forming a three-dimensional structure that can cover the outside of the shielding layer 150. Specifically, the overlapping protective layer 160 is, for example, a braided sleeve, which may directly contact the shielding layer 150, the shielding layer 150 directly contacting the plurality of wires. Here, the overlapping protection layer 160 may be woven by flexible insulating material in the form of strip, thread or filament, such as polymer, cotton, etc., but the utility model is not limited thereto.

The shielding layer 150 may include a plurality of conductive materials forming a mesh structure or a braided structure, and covers the covering layers 111, 121, 131, 141 of the conductive wires. In the present embodiment, the shielding layer 150 is, for example, a Tinned Copper braided wire braided structure (Tinned Copper braided wire) with a braiding rate of 65% or more, so as to dissipate external electrostatic interference, but the present invention is not limited thereto. In one embodiment, the braiding rate of the shielding layer 150 may be greater than or equal to 80% to provide better shielding effect. In other embodiments, the shielding layer 150 may be made of pure copper or copper-clad steel, and is not limited to a mesh or a braided structure.

Further, in the present embodiment, an end 211a of the first portion 211 of the conductive shell 210 is aligned with an end 212a of the second portion 212, and the shielding layer 150 is, for example, crimped or welded to the end 211a or the end 212 a. That is, the shielding layer 150 is pressed between the end 211a of the first portion 211 and the end 212a of the second portion 212, so that the conductive shell 210 and the shielding layer 150 are electrically connected, and the grounding effect is better and less susceptible to interference.

With the above configuration, the cable 100 does not need to be additionally provided with a multi-layer shield (such as an Aluminum metallic sheath) and a PVC outer casing, and the cable 100 uses an overlapping protection layer 160 woven by a flexible insulating material and having pores as the outermost layer, so that the cable is more flexible and looks more textured. In addition, the use of the shielding layer 150 having a mesh or braid structure with a braid rate of 65% or more can provide better overall flexibility of the cable 100 while maintaining signal transmission quality. Experiments show that the cable 100 of the present embodiment satisfies high-speed signal quality.

Fig. 4-6 are cross-sectional schematic views of various cables according to other embodiments of the present invention. Referring to fig. 4, in the present embodiment, the cable 100B is slightly different from the cable 100 of fig. 3 in that: the cable 100B of the present embodiment may also include a drain wire 170, and the shielding layer 150 covers the drain wire 170 and is in contact with and in conduction with the drain wire 170. The Drain Wire 170 is, for example, a 28AWG Tinned Copper Wire (28AWG Tinned Copper Wire), which is used for grounding and reducing electromagnetic interference.

Referring to fig. 5, in the present embodiment, a cable 100C is slightly different from the cable 100 of fig. 3 in that: the cable 100C of the present embodiment further includes a plurality of filling members 180 disposed in the shielding layer 150. Specifically, the filling member 180 is, for example, a linear polymer or a cotton thread, but the present invention is not limited thereto. The filling member 180 is used to fill up the shielding layer 150 and is located outside the power line 110, the ground line 120, the first differential signal line 130 and the second differential signal line 140 to increase the drawing force of the cable 100C. The filling member 180 is disposed between the cladding layers 111, 121, 131, 141 of the conductive wires, and can be twisted with any one of the power line 110, the ground line 120, the first differential signal line 130, and the second differential signal line 140. In the present embodiment, the single wire diameter of the filling member 180 is thicker than that of the overlapping protective layer 160 to provide toughness, but the present invention is not limited thereto.

Referring to fig. 6, in the present embodiment, a cable 100D is slightly different from the cable 100C of fig. 5. Specifically, the filling members 180 of the present embodiment are respectively located in the coating layers 111, 121, 131, and 141. That is, the filling member 180 may be doped in the insulating material during forming the cladding layers 111, 121, 131, 141 of the power line 110, the ground line 120, the first differential signal line 130, and the second differential signal line 140, respectively, so as to increase the structural strength of a single conductive wire (i.e., the power line 110, the ground line 120, the first differential signal line 130, and the second differential signal line 140), thereby improving the pulling force of the cable 100D. Of course, in other embodiments, a plurality of filling members may be located at the positions shown in fig. 5 and fig. 6 at the same time to increase the overall strength and the drawing force of the cable, which is not limited by the utility model.

Fig. 7 is a partially disassembled schematic view of the cable of fig. 1. In the embodiment, the first differential signal line 130 and the second differential signal line 140 of the cable 100 form a twisted pair, and the power line 110 and the ground line 120 are not twisted with each other. In some embodiments, the first differential signal line 130 and the second differential signal line 140 form a twisted pair, and the power line 110 and the ground line 120 also form a twisted pair. In some embodiments, the power line 110, the ground line 120, the first differential signal line 130, and the second differential signal line 140 are twisted around each other. In some embodiments, when the data signal rate requirement is low, the power line 110, the ground line 120, the first differential signal line 130 and the second differential signal line 140 are not twisted around each other.

In summary, the cable of the present invention includes a plurality of conductive wires, a shielding layer and an overlapping protection layer. Because the cable does not need to additionally arrange a multi-layer shield (such as an Aluminum metallic Polyester) and an outer sleeve shell made of PVC material, the flexibility of the cable is better, and the periphery of the cable is provided with an overlapping protective layer, so that the appearance of the cable is more textured. In addition, the shielding layer can be conducted with the conductive shell of the connector, so that the grounding effect is better, and the connector is less prone to interference. In some embodiments, the cable may also include a plurality of fillers to increase the pullout force of the cable. In some embodiments, the cable may also include a drain wire for grounding and reducing electromagnetic interference. In some embodiments, by twisting the signal wires in the conductors, the signal transmission rate and its quality can also be improved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
