Description

Technical Field

[0001] This utility model relates to the field of HDMI cable technology, and in particular to an HDMI cable that is easy to process later. Background Technology

[0002] After HDMI cables are manufactured, they require further processing to connect the HDMI connectors to the cable, forming the finished product. HDMI cables contain multiple internal connecting wires. Currently, these internal connecting wires typically use a single-piece insulating layer to wrap two conductors. When connecting the HDMI connector, workers need to cut the insulating layer to separate the two conductors inside the internal connecting wire and then connect them separately. Because the single-piece insulating layer is relatively thick, this increases the difficulty of post-processing and reduces production efficiency. Utility Model Content

[0003] This invention provides an HDMI cable that facilitates post-processing, thereby improving production efficiency.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides an HDMI cable that is easy to process later, including an outer sheath, a shielding layer, a plurality of first inner connecting wires and a plurality of second inner connecting wires; the outer sheath wraps around the outside of the shielding layer, and the first and second inner connecting wires are both located inside the shielding layer; the first inner connecting wire includes two core wires, a ground wire, an outer shielding layer and a covering layer, the covering layer wraps around the outside of the outer shielding layer, and the outer shielding layer encloses both the two core wires and the ground wire, the two core wires are parallel to each other and abut together, and each core wire includes a central conductor and an insulating layer wrapped around the central conductor.

[0006] In some embodiments, the grounding wire is located in a groove between the two core wires, and the grounding wire abuts against the two core wires respectively.

[0007] In some embodiments, the grounding wire is located inside the outer tangent of the two core wires.

[0008] In some embodiments, the shielding layer includes an aluminum foil shielding layer and an aluminum-magnesium wire shielding layer, wherein the aluminum-magnesium wire shielding layer is wrapped around the outside of the aluminum foil shielding layer.

[0009] In some embodiments, the second inner connection wire includes an inner conductor and an inner conductor insulation layer, wherein the inner conductor insulation layer encloses the inner conductor.

[0010] In some embodiments, both the first internal connecting line and the second internal connecting line are provided with five wires.

[0011] In some embodiments, the first inner connecting line surrounds the outside of the second inner connecting line.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. The two core wires included in the first inner connecting wire of this utility model are independent of each other. Both core wires include a central conductor and an insulation layer wrapped around the outside of the central conductor. The insulation layers of the two core wires are in contact with each other. During the later processing, after cutting the outer shielding layer and the covering layer, the two core wires are separated. Moreover, the insulation layers of the two core wires are not integrally formed and are thinner, making it easier to expose the central conductor, thereby facilitating the later processing and improving production efficiency.

[0014] 2. The grounding wire is located inside the outer tangent of the two core wires and does not protrude from the outer tangent of the two core wires, making the outer shielding layer's wrapping structure more regular;

[0015] 3. The shielding layer of the entire HDMI cable includes an aluminum foil shielding layer and an aluminum-magnesium wire shielding layer, which can improve the shielding effect. Attached Figure Description

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides an HDMI connection cable that is easy to process later, such as... Figure 1 and Figure 2 As shown, the cable includes an outer sheath 100, a shielding layer 200, multiple first inner connecting wires 300, and multiple second inner connecting wires 400. The outer sheath 100 wraps around the outside of the shielding layer 200, while the first inner connecting wires 300 and second inner connecting wires 400 are located inside the shielding layer 200. The shielding layer 200 serves to shield the signal, reducing external interference to the internal signal and improving signal transmission quality. The outer sheath 100 provides dust protection for the shielding layer 200, the first inner connecting wires 300, and the second inner connecting wires 400, and can also bundle the wires, making the entire HDMI cable a unified unit. The outer sheath 100 can be made of PVC material.

[0027] The first inner connection line 300 includes two core wires 310, a ground wire 320, an outer shielding layer 330, and a covering layer 340. The covering layer 340 wraps around the outer shielding layer 330, which encloses the two core wires 310 and the ground wire 320. The outer shielding layer 330 also serves as signal shielding, reducing signal interference between adjacent first inner connection lines 300 and improving signal transmission quality. The covering layer 340 provides dust protection for the outer shielding layer 330, the two core wires 310, and the ground wire 320, and can also bundle the wires, making the first inner connection line 300 an independent wire.

[0028] Two core wires 310 are parallel to each other and abut together. Each core wire 310 includes a center conductor 311 and an insulating layer 312 wrapped around the center conductor 311. The center conductor 311 is used to transmit signals, and the insulating layer 312 serves as insulation. Thus, the two core wires 310 are independent of each other. The insulating layers 312 of the two core wires 310 abut together. During the later processing, after cutting the outer shielding layer 330 and the covering layer 340, the two core wires 310 are separated. Moreover, the insulating layers 312 of the two core wires 310 are not integrally formed and are thinner, making it easier to expose the center conductor 311, which facilitates the later processing and improves production efficiency.

[0029] In some embodiments, since the cross-sectional shape of the core wire 310 is circular, when the two core wires 310 abut together, a groove 350 is formed on both sides of the abutment position of the two core wires 310. The ground wire 320 is located in one of the grooves 350 between the two core wires 310, and the ground wire 320 abuts against the two core wires 310 respectively. The ground wire 320 is positioned by the outer side of the two core wires 310, so that the ground wire 320 is not easy to move inside the outer shielding layer 330 and can maintain a relatively stable position, which is convenient for the outer shielding layer 330 to wrap.

[0030] Furthermore, the grounding wire 320 is located inside the outer tangent of the two core wires 310. Since the cross-sectional shape of the core wire 310 is circular, and the two core wires 310 have two outer tangents, the grounding wire 320 does not protrude from the outer tangent of the two core wires 310, the wrapping structure of the outer shielding layer 330 is more regular, the wrapping operation is easier to achieve, and the outer periphery of the outer shielding layer 330 can be capsule-shaped.

[0031] In some embodiments, the insulating layer 312 may be made of foamed material, and the outer shielding layer 330 may be made of aluminum foil.

[0032] In some embodiments, the shielding layer 200 includes an aluminum foil shielding layer 210 and an aluminum-magnesium wire shielding layer 220. The aluminum-magnesium wire shielding layer 220 is wrapped around the outside of the aluminum foil shielding layer 210, and the outer sheath 100 is wrapped around the outside of the aluminum-magnesium wire shielding layer 220. The first inner connecting line 300 and the second inner connecting line 400 are located inside the aluminum foil shielding layer 210. This embodiment employs a two-layer shielding structure, which can improve the shielding effect and further ensure the quality of signal transmission.

[0033] In some embodiments, the second inner connecting wire 400 includes an inner conductor 410 and an inner conductor insulation layer 420, the inner conductor insulation layer 420 wrapping the inner conductor 410. The inner conductor 410 is used for signal transmission, and the inner conductor insulation layer 420 serves as insulation protection. The inner conductor 410 can be a single wire or multiple wires twisted together.

[0034] In some embodiments, both the first inner connecting wire 300 and the second inner connecting wire 400 are provided with five wires to meet the needs of the connector.

[0035] Furthermore, the first inner connecting line 300 is positioned outside the second inner connecting line 400. The first inner connecting line 300 is larger in size; the larger the radius of the circle, the larger its circumference. This structural layout conforms to the characteristic of a smaller inner diameter and a larger outer diameter, making the entire connecting cable more compact. Both the first inner connecting line 300 and the second inner connecting line 400 can be evenly distributed relative to the central axis of the entire HDMI connecting cable.

[0036] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
