Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The cable assembly provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the present application discloses a cable assembly including a support body 100 and a cable 200. The support body 100 may provide a supporting force to the cable 200 to facilitate the assembly of the cable 200, and the support body 100 may have a unitary structure to support the entire cable 200. The cable 200 is used for signal transmission, and the cable 200 is disposed on the support body 100. Alternatively, the cable 200 may be a flexible flat cable, which may be a general flexible flat cable, or a high frequency flexible flat cable.

In this embodiment, the cable 200 may include a wire body 210, a first electrical connection portion 220 and a second electrical connection portion 230, the first electrical connection portion 220 is disposed at one end of the wire body 210, the second electrical connection portion 230 is disposed at the other end of the wire body 210, and the first electrical connection portion 220 and the second electrical connection portion 230 are portions of the wire body 210 electrically connected to different components, respectively. The wire body 210 includes a plurality of electric conductors arranged at intervals and insulators wrapping the electric conductors, the electric conductors are electrically connected with the first electric connection portion 220 and the second electric connection portion 230 respectively, the extending direction of the electric conductors is consistent with the extending direction of the whole wire body 210, and a space around each electric conductor is covered by the insulator, that is, a part of the insulator is filled between adjacent electric conductors, so that the adjacent electric conductors are insulated.

The insulator is provided with at least one dividing slit 211, the dividing slit 211 penetrates the insulator, specifically, the dividing slit 211 penetrates the insulator in a direction perpendicular to the extending direction of the wire body 210, and the dividing slit 211 is positioned between any two adjacent electric conductors. Alternatively, the dividing slits 211 may be formed by laser cutting or the like. After the dividing slit 211 is arranged, the conductor can still be wrapped by the insulator, so that the reliability of the conductor cannot be influenced by the dividing slit 211, meanwhile, the insulator is split by the dividing slit 211, and the positions of all parts of the insulator can be changed, so that the insulator is softer, the deformation capacity of the insulator is stronger, the shape of the cable 200 can be flexibly adjusted according to actual conditions, and the cable 200 can be connected with other parts more easily. Therefore, the cable assembly is low in wiring difficulty.

In addition, since the wire body 210 includes at least two electrical conductors, different electrical conductors may be supplied with different types of signals, which may include, for example, high-speed signals, low-speed signals, current, and the like. The wire body 210 may also enable coexistence between interfaces of different differential impedances, such as: the coexistence of the HDMI (High Definition Multimedia Interface) with the differential impedance of approximately 100 Ω and the USB3.0 with the differential impedance of approximately 90 Ω effectively reduces the number of cable components included in the same device.

The insulator can be provided with only one dividing slit 211, but the deformation capability of the insulator is still not ideal at the moment, so that the insulator can be provided with at least two dividing slits 211, the electric conductors are positioned between the adjacent dividing slits 211, namely, the adjacent dividing slits 211 are separated by the electric conductors, and only one dividing slit 211 can be arranged between the adjacent electric conductors, thereby not only being convenient for forming the dividing slits 211, but also avoiding the insulating materials between the adjacent electric conductors from being scratched to expose the electric conductors. In addition, the plurality of dividing slits 211 are distributed at different positions of the insulator, so that the insulator has stronger deformability and is more convenient to wire. It should be noted that the number of the dividing slits 211 can be flexibly selected, and the dividing slits 211 do not need to be formed between every two adjacent conductors.

In addition, both ends of the insulator are of an integral structure, and the dividing slit 211 is located between both ends of the insulator. In other words, the dividing slits 211 do not extend to both ends of the insulator, but are concentrated near the middle region of the insulator, which has a greater influence on the deformability of the wire body 210, and thus the arrangement of the dividing slits 211 is more advantageous in improving the deformability of the wire body 210. And, both ends of the insulator are still of an integral structure, so that the insulator can be connected with other parts of the cable assembly as an integral part, and therefore, the structure is more convenient for processing the cable assembly.

The number of the wire bodies 210 may be only one, and in a case where the number of the electric conductors is constant, the width of the wire bodies 210 is substantially equal to the width of the insulator after all the electric conductors are tiled and the insulator covers all the electric conductors, and obviously, the width of the wire bodies 210 is large. In another optional embodiment, the number of the wire bodies 210 is at least two, and the wire bodies include a first wire body 212 and a second wire body 213, a first end 212a of the first wire body 212 and a third end 213a of the second wire body 213 are respectively located on opposite sides of the support body 100, a second end 212b of the first wire body 212 and a fourth end 213b of the second wire body 213 are respectively located on opposite sides of the support body 100, and at least one of the first wire body 212 and the second wire body 213 is provided with a dividing slit 211. This embodiment can divide all the electrical conductors contained in the wire body 210 into at least two layers, so that the width of the wire body 210 can be greatly reduced under the condition of a certain number of electrical conductors, so that the cable assembly can be more conveniently arranged in equipment with more restricted space.

In an alternative embodiment, the first end 212a of the first wire body 212 and the second end 212b of the first wire body 212 are both located on the same side of the support body 100, and the third end 213a of the second wire body 213 and the fourth end 213b of the second wire body 213 are both located on the same side of the support body 100. That is, the first wire body 212 and the second wire body 213 are independently distributed on different sides of the support body 100, the structure of the cable assembly is relatively simple, and it can be applied to a case where the first electrical connection portion 220 and the second electrical connection portion 230 need to be arranged on the same side.

The deformation of the wire body 210 may include bending, and may also include twisting, that is, one end of the wire body 210 rotates around the axis of the wire body 210 by a preset angle, where the preset angle may be 30 °, 60 °, 90 °, 120 °, 180 °, and the like, which is not limited in this embodiment. Alternatively, in a case where the first wire body 212 and the second wire body 213 are both in a twisted state, the first end 212a of the first wire body 212 and the fourth end 213b of the second wire body 213 are both located on the same side of the support body 100, and the third end 213a of the second wire body 213 and the second end 212b of the first wire body 212 are both located on the same side of the support body 100. That is to say, both the first wire body 212 and the second wire body 213 may be twisted, the twisting angle is approximately 180 °, and the widths of the middle portion of the twisted first wire body 212 and the middle portion of the second wire body 213 become smaller, so that both one end of the first wire body 212 and one end of the second wire body 213 may pass through the support body 100, and finally, the first end 212a and the second end 212b of the first wire body 212 are respectively located on different sides of the support body 100, and the third end 213a and the fourth end 213b of the second wire body 213 are located on different sides of the support body 100. This embodiment can change the positions of the first and second

electrical connection portions

220 and 230 by twisting the first and

second wires

212 and 213, thereby being suitable for the case where the first and second

electrical connection portions

220 and 230 need to be located on different sides of the support body 100.

Since the wire body 210 can be deformed, when the wire body 210 is processed, the structure of the wire body 210 and the arrangement positions of the first electrical connection portion 220 and the second electrical connection portion 230 on the wire body 210 can be flexibly designed according to the application environment of the cable assembly. In an alternative embodiment, the first electrical connection portion 220 and the second electrical connection portion 230 are both located on the same side of the wire body 210 when the wire body 210 is in the flattened state. In this case, the wire body 210 may be disposed on the support body 100 in a flattened state, and when the wire body 210 is assembled with the support body 100, the wire body 210 is in the flattened state. In this embodiment, the same conductive body can be electrically connected to the corresponding portions of the first electrical connection portion 220 and the second electrical connection portion 230 without bending, so this embodiment is suitable for the case where the corresponding portions of the first electrical connection portion 220 and the second electrical connection portion 230 correspond to each other one by one along the extending direction of the wire body 210 (for example, the pin sequences of the first electrical connection portion 220 and the second electrical connection portion 230 are the same). Of course, the wire body 210 may be twisted and then disposed on the support body 100, and at this time, the first electrical connection portion 220 and the second electrical connection portion 230 of the wire body 210 may face different sides, so as to be suitable for a case where two ends of the wire body 210 are respectively located on different sides of the support body 100.

In another alternative embodiment, the first electrical connection portion 220 and the second electrical connection portion 230 are respectively located on two opposite sides of the wire body 210 when the wire body 210 is in the flattened state. In this case, the wire body 210 may be disposed on the support body 100 in a flattened state, and when the wire body 210 is assembled with the support body 100, the wire body 210 is in the flattened state. In this embodiment, the same electrical conductor can be electrically connected to the corresponding portions of the first electrical connection portion 220 and the second electrical connection portion 230 without bending, so this embodiment is suitable for the case where the corresponding portions of the first electrical connection portion 220 and the second electrical connection portion 230 correspond to each other one by one along the extending direction of the wire body 210, and meanwhile, since the first electrical connection portion 220 and the second electrical connection portion 230 are respectively located on opposite sides of the wire body 210, in this embodiment, the first electrical connection portion 220 and the second electrical connection portion 230 may be located on different sides of the support body 100. Of course, the wire body 210 may also be twisted and then disposed on the support body 100, and at this time, the first electrical connection portion 220 and the second electrical connection portion 230 of the wire body 210 face to the same side, so that the two ends of the wire body 210 are respectively located on the same side of the support body 100. Further, the corresponding relationship between the first electrical connection portion 220 and the second electrical connection portion 230 can be changed by twisting, specifically referring to fig. 2, the first pin 201 and the second pin 202 are connected by an electrical conductor, that is, the pin corresponding to the first pin 201 is the second pin 202, but the first pin 201 and the second pin 202 are not distributed along the extending direction of the wire body 210, so that this way can be applied to the case where the pin order of the first electrical connection portion 220 and the second electrical connection portion 230 is different.

The wire body 210 may be connected to the support body 100 by bonding, and in order to further improve the connection reliability between the wire body 210 and the support body 100, the cable assembly may further include a first cover plate 310 and a second cover plate 320, and both the first cover plate 310 and the second cover plate 320 are connected to the support body 100. One end of the wire body 210 is located between the first cover plate 310 and the support body 100, the other end of the wire body 210 is located between the second cover plate 320 and the support body 100, and at least a portion of the first electrical connection portion 220, at least a portion of the second electrical connection portion 230, and at least a portion of the dividing slit 211 are exposed with respect to the first cover plate 310 and the second cover plate 320. The first cover plate 310 and the second cover plate 320 can respectively apply acting force to two ends of the wire body 210, so as to prevent the wire body 210 from being separated from the support body 100, and meanwhile, the first cover plate 310 and the second cover plate 320 do not affect the connection between the first electrical connection portion 220 and the second electrical connection portion 230 and other components, and do not limit the deformation of the wire body 210 under the action of the dividing slit 211.

Optionally, the materials of the first cover plate 310 and the second cover plate 320 may be plastics, metals, or composite materials of plastics and metals, the first cover plate 310 and the second cover plate 320 may be connected to the support body 100 by clamping, screwing, bonding, or the like, and in addition, the first cover plate 310 and the second cover plate 320 may or may not be provided with a shielding structure.

As mentioned above, the supporting body 100 may be a one-piece structure, but this structure is not favorable for the deformation of the wire body 210, and therefore, in another alternative embodiment, the supporting body 100 includes a first supporting portion 110 and a second supporting portion 120, the first supporting portion 110 and the second supporting portion 120 are arranged at intervals, one end of the wire body 210 is connected to the first supporting portion 110, and the other end of the wire body 210 is connected to the second supporting portion 120. Since the first and

second support parts

110 and 120 are separately provided, the support body 100 does not substantially restrict the deformation of the wire body 210. Further, a space between the first supporting portion 110 and the second supporting portion 120 can allow one end of the wire body 210 to pass through, thereby facilitating to implement a scheme that two ends of the wire body 210 are respectively located at different sides of the supporting body 100.

In order to further limit the position of the wire body 210 and at the same time facilitate the assembly of the wire body 210, the first support portion 110 and the second support portion 120 are each provided with a groove, and at least a portion of the wire body 210 is located in the groove. The side wall of the groove can be in limit fit with the side surface of the wire body 210, so that the position of the wire body 210 is limited, and meanwhile, reference can be provided for the assembly of the wire body 210, so that the assembly of the wire body 210 is facilitated. It should be noted that, after the wire body 210 and the support body 100 are assembled, the surfaces of the first electrical connection portion 220 and the second electrical connection portion 230 may be flush with the top surface of the groove, may protrude from the top surface of the groove, or may be lower than the top surface of the groove, as long as the first electrical connection portion 220 and the second electrical connection portion 230 are connected to other components.

In order to improve the structural strength of the wire body 210, the cable assembly may further include a first reinforcing plate 410 and a second reinforcing plate 420, the first reinforcing plate 410 and the second reinforcing plate 420 are both connected to the wire body 210, the first reinforcing plate 410 is disposed opposite to the first electrical connection portion 220, and the second reinforcing plate 420 is disposed opposite to the second electrical connection portion 230. Thus, the first stiffener 410 can enhance the structural strength of the first electrical connection portion 220, and the second stiffener 420 can enhance the structural strength of the second electrical connection portion 230.

Because the wire body 210 is provided with the dividing slit 211, the part of the wire body 210 provided with the dividing slit 211 is in a dispersed strip-shaped structure, if the length of the cable assembly is smaller, the structure basically does not bring adverse effects, but if the length of the cable assembly is larger, the structure easily causes the problems that the wire body 210 swings, interferes with other parts and the like. To this end, in an alternative embodiment, the cable assembly further comprises a furling member detachably connected to the wire body 210, and the furling member may surround a portion of the wire body 210 where the split seam 211 is provided. Alternatively, the gathering member may be a string, tape, band, or the like, which has a securing function. When the part of the line body 210 with the dividing slit 211 needs to be fixed, the furling piece is connected with the line body 210, so that the furling piece surrounds the part of the line body 210 with the dividing slit 211, and the problems of swinging, interference with other parts and the like of the part can be prevented; when the wire body 210 needs to be deformed, the shape of the wire body 210 can be freely changed by detaching the furling piece.

Alternatively, the first electrical connection portion 220 and the second electrical connection portion 230 may be contact-type structures, but in order to facilitate connection and separation between the cable assembly and other components, at least one of the first electrical connection portion 220 and the second electrical connection portion 230 may be set as a gold finger, and at this time, connection and separation between the cable assembly and other components may be conveniently achieved only through a simple plugging and unplugging action. The structure of the gold finger can be shown in fig. 5 and fig. 6, wherein X is a pin pitch (unit is mm) of the gold finger, and optionally X can be 0.2-1.0 mm; n is the pin number of the golden finger, and optionally, N can be 6-96. The gold finger may not be provided with a plating layer, or may be provided with a plating layer, and the plating layer material may be tin, silver, nickel, gold, or other materials, which is not limited in this application.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
