Patent Application

This application claims the benefit of the filing date under 35 U.S.C. § 119(a)-(d) of Chinese Patent Application No. 202110562052.8, filed on May 21, 2021.
Embodiments of the present disclosure generally relate to a cable, and more particularly, to a ribbon cable, such as a twinaxial cable, that is capable of data transmission at high data transmission rates.
In the related art, a high-speed data transmission ribbon cable such as a twinaxial cable mainly includes a plurality of cable groups arranged side by side, a covering film is provided on one side of the plurality of cable groups, and the plurality of cable groups are bonded to the covering film by hot melt adhesive on the covering film to form the ribbon cable. However, such a cable fixing structure of the existing ribbon cable is extremely unstable, and the cables easily fall off and become loose, which makes the assembly unusable. In addition, because the covering film is only attached to one side of these cable groups, the hot melt adhesive on the covering film is exposed to the air, is easily affected by the external environment, and is prone to failure, which is even more unfavorable for the fixing of the cable.
A ribbon cable includes a plurality of cable groups arranged side by side with a gap between each pair of adjacent cable groups, a first covering film arranged on a first side of the cable groups, and a second covering film arranged on a second side of the cable groups opposite the first covering film. The first covering film has a first bonding portion and a first spacing portion. The second covering film has a second bonding portion and a second spacing portion. The first bonding portion and the second bonding portion are bonded to each of the cable groups. The first spacing portion and the second spacing portion are located at the gap and are separated from each other.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Embodiments of the present disclosure will be described hereinafter in detail taken in conjunction with the accompanying drawings. In the description, the same or similar parts are indicated by the same or similar reference numerals. The description of embodiments of the present disclosure hereinafter with reference to the accompanying drawings is intended to explain the general inventive concept of the present disclosure and should not be construed as a limitation on the present disclosure.
In addition, in the following detailed description, for the sake of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may also be practiced without these specific details. In other instances, well-known structures and devices are illustrated schematically in order to simplify the drawing.
In the embodiment shown in
As shown in
In an embodiment of the ribbon cable 10, the covering films 200, 300 are provided on opposite sides of the two or more cable groups 100 arranged side by side to form a stable double-sided cable fixing structure, thus the cables 100 do not easily fall off and become loose.
A surface of the first covering film 200 facing the two or more cable groups 100 is provided with hot melt adhesive by which the first covering film 200 is bonded to each cable group 100 of the cable groups 100, and a surface of the second covering film 300 facing the cable groups 100 is provided with hot melt adhesive by which the second covering film 300 is bonded to each cable group 100 of the cable groups 100. That is, the first covering film 200 and the second covering film 300 may be bonded to the cable groups 100 by thermal fusion. In another embodiment, the first covering film 200 and the second covering film 300 may be bonded to the cable groups 100 by an adhesive. In the ribbon cable 10, since a double-sided covering structure is adopted, the hot melt adhesive on the covering films 200, 300 is not in contact with air, is less affected by the external environment, and is not prone to failure.
As shown in
In an embodiment, the first covering film 200 includes an insulation polyester tape or a shielding tape, and the second covering film 300 includes an insulation polyester tape or a shielding tape. That is, the first covering film 200 and/or the second covering film 300 may provide improved electromagnetic shielding for the cable groups 100, and may take the form of a layer/tape. The first covering film 200 and/or the second covering film 300 may be made of an insulation polymer material. For example, the first covering film 200 and/or the second covering film 300 may be made of an insulation material such as polyethylene terephthalate (abbreviated as “PET”). The first covering film 200 and/or the second covering film 300 may also be made of a metallic shielding material. For example, the first covering film 200 and/or the second covering film 300 may be made of a metal shielding material such as copper or aluminum. In other embodiments, the first covering film 200 and/or the second covering film 300 may also be made of other materials suitable for the fixing and shielding of high-speed cables.
As shown in
As shown in
The ribbon cable 10 provided by the present disclosure may be a high-speed data transmission ribbon cable such as a twinaxial cable. The ribbon cable 10 can be directly produced with existing equipment, without the need to modify the existing equipment or add additional film sticking devices.
