referring to fig. 2 and fig. 3, the present invention provides a foldable flat cable structure 1, which includes a main covering member 10 and a plurality of transmission lines 17. The main coating 10 is strip-shaped, and the transmission lines 17 are disposed side by side to cover the main coating 10. As shown in fig. 3, the overall covering member 10 has at least one folding notch 18, the at least one folding notch 18 exposes the transmission line 17, and the overall covering member 10 is at least divided into a first section 101 and a second section 102, and the second section 102 is adapted to be folded relative to the first section 101 through the folding notch 18 to change the shape of the transmission flat cable structure 1. As shown in fig. 2, each transmission line 17 includes a conductive line 170 and an inner coating member 171 covering the conductive line 170. The folding slits 18 can be formed by cutting the overall covering member 10, but are not limited thereto.
As mentioned above, the overall covering member 10 of the flat cable structure 1 of the present invention has the at least one folding notch 18, so that the folding operation can be performed in a proper order in compliance with the space of the installation environment, thereby avoiding the problems of line falling or poor electrical contact caused by uneven stress in a narrow space. In addition, the at least one folding notch 18 can also reduce the flexibility of the overall covering member 10, so as to reduce the thickness of the transmission flat cable structure 1 after folding and folding. In addition, the transmission flat cable structure 1 of the present invention also solves the problem that it is not easy to put into a narrow space after bending.
As shown in fig. 2, in an embodiment, the transmission line 17 of the present invention may be formed as a plurality of transmission line structures 11. Each transmission line structure 11 includes a first transmission line bundle 12, a second transmission line bundle 13, and a ground line 14 disposed between the first transmission line bundle 12 and the second transmission line bundle 13. The first transmission line bundle 12 is covered by a first conductive covering 15, the second transmission line bundle 13 is covered by a second conductive covering 16, and the ground line 14 is electrically contacted to the outer surface of the first conductive covering 15 and the outer surface of the second conductive covering 16. The first transmission line bundle 12 and the second transmission line bundle 13 respectively include two transmission lines 17. The transmission flat cable structure 1 can be connected between a socket member (not shown) and a circuit board (not shown) having a plurality of connection portions (e.g., gold fingers), thereby transmitting high frequency signals such as audio/video signals or data signals. The connection may be by way of welding, but is not limited thereto. The transmission line structures 11 are arranged in parallel and in a row to form a flat cable. The ground line 14 may be connected to ground by means to which the transmission flat cable structure 1 is connected, in order to discharge excess charge. The ground wire 14 may be copper wire, silver wire, gold wire, or other highly conductive metal or alloy. The first conductive coating 15 and the second conductive coating 16 can be aluminum foil coatings to improve electrical conductivity. But not limited thereto, the material of the first conductive coating 15 and the second conductive coating 16 can also be other conductive metals such as copper or alloys, such as aluminum alloy.
As shown in fig. 2, in the embodiment, the two transmission lines 17 of the first transmission line bundle 12 and the two transmission lines 17 of the second transmission line bundle 13 respectively have the wires 170 and the inner coating member 171 covering the wires 170 to be insulated from each other. The first conductive coating 15 contacts the inner coatings 171 of the two corresponding transmission lines 17, and the second conductive coating 16 contacts the inner coatings 171 of the two corresponding transmission lines 17. In addition, the two transmission lines 17 of the first transmission line bundle 12 and the two transmission lines 17 of the second transmission line bundle 13 are also close to each other to save space. The conductive wires 170 may be copper wires, silver wires, gold wires, or other highly conductive metals or alloys.
In the embodiment shown in fig. 3, the at least one folding notch 18 may be located on one side of the overall covering member 10, or the folding notches 18 may be respectively disposed on two opposite sides of the overall covering member 10. In fig. 3, the at least one flip-chip cutout 18 may be open, i.e. the transmission line 17 is exposed within the range of the flip-chip cutout 18. For example, the at least one fold-over notch 18 may be a circular cut opening that circles around the overall covering 10, but is not limited thereto. Referring to fig. 2, when the transmission line 17 is exposed out of the turning notch 18, the first conductive coating 15 and the second conductive coating 16 are coated outside the transmission line 17, so that the first conductive coating 15 and the second conductive coating 16 can be brought into contact with an electronic device case (not shown) disposed on the transmission flat cable structure 1 to achieve a grounding effect.
In an embodiment, as shown in fig. 9, the at least one turnover slit 18 may also be formed by a plurality of openings 181. The openings 181 may be arranged in a dotted line shape, and the portion of the overall covering member 10 having the openings 181 has a weak structural strength, so that the overall covering member may also have a folding effect.
As shown in fig. 3 and 4, the overall covering member 10 has an extending direction L before being folded, and the at least one folding notch 18 has an included angle θ with the extending direction L. In fig. 3 and 4, the included angle θ is 45 degrees, so that when the second segment 102 is folded with respect to the first segment 101 through the folding notch 18, the second segment 102 can be perpendicular to the first segment 101. But is not limited thereto, the included angle θ may range from more than 0 degrees to less than 180 degrees.
As shown in fig. 5 to 7, in an embodiment, the overall covering member 10 may further have another folding notch 18 thereon, so that the overall covering member 10 is divided into the first section 101, the second section 102 and the third section 103. The folding notch 18 between the second section 102 and the third section 103 can be perpendicular to the extending direction L, i.e. the included angle θ is 90 degrees, so that the third section 103 can be folded along the extending direction L relative to the second section 102 (as shown in fig. 6), or further the third section 103 can be integrally overlapped on the second section 102 (as shown in fig. 7). It should be noted that a single transmission flat cable structure 1 may have one or more folding notches 8, and each folding notch 8 may form the same or different included angle θ with the extending direction L, and is not limited to the form shown in the drawings.
As shown in fig. 8. In an embodiment, the transmission flat cable structure 1 of the present invention may further include a covering member 19. The covering member 19 is adapted to cover a part of the folded-back overall covering member 10 by winding so as to position the transmission flat cable structure 1 in the folded-back shape. The covering member 19 can maintain the state that the transmission lines 17 are exposed out of the folding notches 18, i.e. only used for positioning the folded structure of the transmission flat cable structure 1. But not limited thereto, for example, the wrapping manner of the wrapping member 19 may be changed to cover the folding slits 18 to protect the transmission lines 17. The covering member 19 is a repeatedly tearable adhesive tape, but is not limited thereto.
While the utility model has been described in terms of preferred embodiments, it will be understood by those skilled in the art that the examples are intended in a descriptive sense only and not for purposes of limitation. It should be noted that all changes and substitutions equivalent to the embodiments are intended to be included within the scope of the present invention.
