This application claims the benefit of Chinese Patent Application No. CN 202120677646.9 filed on Apr. 1, 2021 in the China National Intellectual Property Administration, the whole disclosure of which is incorporated herein by reference.
The present disclosure relates to a combined cable including a row of cables.
S flat combined cable according to the prior art generally includes a row of cable groups. Each cable group includes at least one cable arranged side by side. Adhesive tape is adhered to upper and/or lower side surfaces of a row of cable groups. A row of cable groups is connected and secured together by adhesive tapes adhered to the upper and/or lower surfaces thereof.
For a combined cable in which one piece of adhesive tape is adhered to the upper and lower side surfaces of a row of cable groups, respectively, the cost of the combined cable is relatively high, and the stiffness of the combined cable will be too rigid, making bending of the same difficult. This increases the difficulty of soldering the cable to a circuit board.
For a combined cable in which only one adhesive tape is adhered to the upper or lower side surfaces of a row of cable groups, it is easy for the adhesive tape to fall off and or become loose. Further, the hot melt glue of the adhesive tape between two adjacent cable groups is exposed to the air, which is easily affected by the environment and thus fails due to aging.
According to an embodiment of the present disclosure, a combined cable includes at least two cable groups, each comprising at least one cable arranged side by side. Each cable group further comprises an adhesive layer wrapping a periphery of the at least one cable and having adhesion agent located on an outside of the adhesive layer. Each cable group further includes two coating layers, respectively adhered to a periphery of the adhesive layer of each cable group with the adhesion agent from upper and lower sides of the at least two cable groups. The coating layers located between adjacent two cable groups are detachably abutted together.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes 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 be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
According to an embodiment of the present disclosure, a combined cable is provided. The combined cable includes at least two cable groups each including at least one cable arranged side by side. Each cable group further includes an adhesive layer wrapping the periphery of the at least one cable and having adhesion agent located on the outside of the adhesive layer. Two coating layers respectively adhered to the periphery of the adhesive layer of each cable group with the adhesion agent from upper and lower sides of the at least two cable groups. The coating layers located between adjacent two cable groups are detachably abutted together.
As shown in
In the combined cable according to the embodiment of the present disclosure, two coating layers 4 serving as the outer layer are adhered to the adhesive layer 3 by the adhesion agent (e.g., hot melt glue) disposed on the outside of the adhesive layer 3, so a flat combined cable 100 with a double-layered film (coating layer) is formed. The coating layer 4 itself does not include the adhesion agent, and the coating layers 4 located between two adjacent cable groups 1 can be detachably abutted together, which can improve the structural stability of the cables in each cable group.
In an exemplary embodiment, the adhesive layer is made of MYLAR material (or PET polyester material). In this way, the adhesive layer 3 is embodied in the form of a wrapped Mylar layer with hot melt glue on its outside, so there are two layers on a microscopic level, that is, a Mylar layer and an adhesion agent layer formed by hot melt glue. In an exemplary embodiment, two coating layers 4 are adhered to the periphery of the adhesive layer 3 of each cable group 1 by means of thermocompression.
In an exemplary embodiment, the shielding layer includes a polyester tape and a metal layer adhered with the polyester tape, wherein the polyester tape may be on the inside or outside of the metal layer. In an alternative embodiment, the shielding layer includes a polyester tape and conductive particles doped in the polyester tape. In another alternative embodiment, the coating layer 4 is an insulating layer, for example, the coating layer 4 may be a polyester insulating layer.
The two coating layer 4 are attached to the upper and lower surfaces of the adhesive layers 3 wrapping around the cables 2, and then are heat-sealed by flattening, so that the two coating layers 4 are adhered to the adhesive 3, and the two coating layers 4 located between the adjacent two cable groups 1 are detachably abutted together, that is, are not bonded together, thereby the combined cable 100 forms a flat banding cable.
As shown in
As shown in
In an exemplary embodiment, the combined cable 100 further includes at least one second auxiliary cable 6 arranged side by side on at least one side of the at least two cable groups 1. The adhesive layer 3 at least partially wraps around the periphery of each second auxiliary cable 6, and the two coating layers 4 are at least partially adhered to the periphery of the adhesive layer 3 wrapping the second auxiliary cable 6, respectively. The second auxiliary cable 6 can be used as signal cable or ground cable.
As shown in
With the combined cable according to the above-mentioned embodiments of the present disclosure, the structural stability can be improved, and the cable wrapped in the adhesive layer is not easy to loosen; the adhesion agent (e.g., hot melt glue) coated on the adhesive layer does not come into contact with the external environment so that it is less affected by the environment and is not easy to fail; and the existing equipment can be used to produce the combined cables, which reduces the cost of production.
In addition, those areas in which it is believed that those of ordinary skill in the art are familiar, have not been described herein in order not to unnecessarily obscure the invention described. Accordingly, it has to be understood that the invention is not to be limited by the specific illustrative embodiments, but only by the scope of the appended claims.

For example, many modifications may be made to the above embodiments by those skilled in this art, and various features described in different embodiments may be freely combined with each other without conflicting in configuration or principle.
Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
As used herein, an element recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural of the elements or steps, unless such exclusion is explicitly stated. Furthermore, references to “one embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular property may include additional such elements not having that property.
