[0050] The description will be made as to the embodiments of the present invention in conjunction with the accompanying drawings in FIGS. 1-11. In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to an electrical component.

[0051] As shown in FIG. 1 to FIG. 11, an electrical component 100 according to certain embodiments of the present invention is a flexible circuit board, and the electrical component 100 can be electrically connected to another mating member (not shown). In other embodiments, the electrical component 100 may be a hard circuit board, or may be a cable structure, and certainly may be a connector type structure.

[0052] FIG. 1 to FIG. 3 show the electrical component 100 according to a first embodiment of the present invention. First, an X-axis direction is defined as a transverse direction, a Y-axis direction is defined as a longitudinal direction, and a Z-axis direction is defined as a vertical direction. The electrical component 100 is substantially a flexible circuit board having a five-layer structure, which includes an insulating base 1. The insulating base 1 extends along the Y-axis direction to substantially form a cuboid shaped. The insulating base 1 can also be in other possible shapes in other embodiments, such as a cube shape. A shielding member 2 is provided outside the insulating base 1.

[0053] The shielding member 2 includes an upper shielding member 21 provided above the insulating base 1 and a lower shielding member 22 provided below the insulating base 1. An insulating layer 3 is provided outside the shielding member 2. The insulating layer 3 includes an upper insulating layer 31 provided above the upper shielding member 21 and a lower insulating layer 32 provided below the lower shielding member 22.

[0054] As shown in FIG. 2 and FIG. 3, multiple conductive bodies 4 are accommodated in the insulating base 1. The conductive bodies 4 include a plurality of power supply bodies 41, a plurality of signal bodies 42 and a plurality of grounding bodies 43. Twelve (12) conductive bodies 4 are provided and are arranged in a single row in the X-axis direction, and are arranged in sequence as: a grounding body 43, two signal bodies 42, a power supply body 41, four signal bodies 42, a power supply body 41, two signal bodies 42, and a grounding body 43. Each of the two signal bodies 42 between the power supply body 41 and the grounding body 43 are used for transmitting differential signals. The grounding bodies 43 and the signal bodies 42 are all flat shaped, and a width of each of the grounding bodies 43 in the X-axis direction is greater than a width of each of the signal bodies 42 in the X-axis direction. A thickness of each of the grounding bodies 43 in the Z-axis direction is equal to a thickness of each of the signal bodies 42 in the Z-axis direction. A length of each of the grounding bodies 43 in the Y-axis direction is equal to a length of each of the signal bodies 42 in the Y-axis direction. Therefore, a volume of each of the grounding bodies 43 is greater than a volume of each of the signal bodies 42. Each of the power supply bodies 41 is cylindrical shaped, and a diameter of each of the power supply bodies 41 is equal to a thickness of the insulating base 1 in the Z-axis direction. That is, the highest point and the lowest point of each of the power supply bodies 41 in the Z-axis direction respectively correspond to an upper surface and a lower surface of the insulating base 1, the highest point and the upper surface are on a same horizontal plane, and the lowest point and the lower surface are on a same horizontal plane. An insulator 5 is provided outside each of the power supply bodies 41 and is tubular shaped, and the insulator 5 protrudes out of the upper surface and the lower surface of the insulating base 1. A shielding layer 6 is provided outside the insulator 5 and is tubular shaped. The shielding layer 6 is in contact with the upper shielding member 21 and the lower shielding member 22 respectively in the Z-axis direction. The insulator 5 protrudes from the upper surface and the lower surface of the insulating base 1, the shielding layer 6 is provided outside the insulator 5, the shielding member 2 is provided on the upper surface and the lower surface of the insulating base 1, and the insulating layer 3 is provided on an upper surface and a lower surface of the shielding member 2. Therefore, the shielding member 2 and the insulating layer 3 appear to protrude outward at a position corresponding to each of the power supply bodies 41.

[0055] As shown in FIG. 3, a distance d1 between each power supply body 41 and an adjacent signal body 42 is greater than a distance d2 between two adjacent signal bodies 42. The distance d1 between each power supply body 41 and the adjacent signal body 42 is greater than a distance d3 between each grounding body 43 and an adjacent signal body 42. The distance d2 between the two adjacent signal bodies 42 is equal to the distance d3 between each grounding body 43 and the adjacent signal body 42. That is, in this embodiment, the distance d1 between each power supply body 41 and the adjacent signal body 42 is greater than the distance d2 between the two adjacent signal bodies 42, and is also greater than the distance d3 between each signal body 42 and the adjacent grounding body 43. This is because each power supply body 41 is cylindrical, and the diameter of each power supply body 41 is much less than the width of each signal body 42 or each grounding body 43 in the X-axis direction, such that a distance between a cylindrical body and a flat body is increased. In other embodiments, the conductive body 4 adjacent to each power supply body 41 may also be a grounding body 43 or a power supply body 41, which depends on practical applications of the electrical component 100 and can be planned and arranged autonomously.

[0056] FIG. 4 and FIG. 5 show an electrical component 100 according to a second embodiment of the present invention, which is different from the first embodiment in that: the structures of the power supply bodies 41, the signal bodies 42 and the grounding bodies 43 are all flat, the insulator 5 provided outside each power supply body 41 is substantially rectangular frame shaped, and the shielding layer 6 provided outside the insulator 5 is also substantially rectangular frame shaped. Neither the insulator 5 nor the shielding layer 6 protrudes out of an upper surface and a lower surface of the insulating base 1. Therefore, an upper surface and a lower surface of the shielding member 2 and an upper surface and a lower surface of the insulating layer 3 are all flat. A distance between each power supply body 41 and an adjacent signal body 42 is d1, a distance between two adjacent signal bodies 42 is d2, and a distance between each grounding body 43 and the adjacent signal body 42 is d3. The distance d1, the distance d2, and the distance d3 are all equal.

[0057] FIG. 6 and FIG. 7 show an electrical component 100 according to a third embodiment of the present invention, which is different from the first embodiment in that: the structures of the power supply bodies 41, the signal bodies 42 and the grounding bodies 43 are all flat, a distance between each power supply body 41 and an adjacent signal body 42 is d1, a distance between two adjacent signal bodies 42 is d2, and a distance between each grounding body 43 and the adjacent signal body 42 is d3. The distance d1, the distance d2, and the distance d3 are all equal. The insulator 5 includes an upper insulator 51 provided above the corresponding power supply body 41 and a lower insulator 52 provided below the corresponding power supply body 41. The shielding layer 6 includes an upper shielding layer 61 provided above the upper insulator 51 and a lower shielding layer 62 provided below the lower insulator 52. Since the structures of the power supply bodies 41, the signal bodies 42 and the grounding bodies 43 are all flat, and the shielding layer 6 does not protrude from an upper surface and a lower surface of the insulating base 1, an upper surface and a lower surface of the shielding member 2 and an upper surface and a lower surface of the insulating layer 3 are flat. A width of each power supply body 41 in an X-axis direction is less than a width of the insulator 5 and a width of the shielding layer 6 in the X-axis direction. A width of the shielding layer 6 in the X-axis direction is equal to the width of the insulator 5 in the X-axis direction. A thickness of the shielding layer 6 in a Z-axis direction is less than a thickness of the insulator 5 in the Z-axis direction.

[0058] FIG. 8 to FIG. 11 show the electrical component 100 according to a fourth embodiment of the present invention, in which multiple conductive bodies 4 are accommodated in the insulating base 1, and the quantity and arrangement of the conductive bodies 4 are identical to those in the first embodiments. That is, the conductive bodies 4 are arranged in a single row in the X-axis direction, and are arranged in sequence as: a grounding body 43, two signal bodies 42, a power supply body 41, four signal bodies 42, a power supply body 41, two signal bodies 42, and a grounding body 43. Each of the two signal bodies 42 between the power supply body 41 and the grounding body 43 are used for transmitting differential signals.

[0059] As shown in FIG. 9 and FIG. 11, the insulating base 1 includes an upper insulating base 11 and a lower insulating base 12 separately formed, and the upper insulating base 11 and the lower insulating base 12 are pressed against each other to fix the signal bodies 42 and the grounding bodies 43.

[0060] As shown in FIG. 11, the upper insulating base 11 is protrudingly provided and formed with a plurality of protruding blocks 111, and each of the protruding blocks 111 corresponds to each of the signal bodies 42 forming the differential pair. Each of the protruding blocks 111 downward abuts a middle portion of the corresponding signal body 42. A width of each of the protruding blocks 111 in its extending direction is gradually reduced, and a tail end of each of the protruding blocks 111 is curve shaped. As shown in FIG. 11, the lower insulating base 12 is upward protrudingly provided with a plurality of protrusions 121, and each of the protrusions 121 is upward protrudingly provided with a protruding portion 122. Two adjacent ones of the protrusions 122 upward abut two opposite sides of one of the signal bodies 42 forming the differential pair. The protruding portion 122 is located between two adjacent ones of the conductive bodies 4 and upward abuts the upper insulating base 11. The lower insulating base 12 is provided with a plurality of slots 123, and each slot 123 is located between two adjacent ones of the protrusions 121. Each of the protruding blocks 111 is located right above a corresponding one of the slots 123. A width W1 of each of the protruding blocks 111 in the X-axis direction is less than a width W2 of each of the slots 123 in the X-axis direction. A protruding length L of each of the protruding blocks 111 in the Z-axis direction is equal to a depth H of each of the slots 123 in the Z-axis direction and is greater than a thickness T of the corresponding signal body 42 in the Z-axis direction.

[0061] As shown in FIG. 9 and FIG. 11, the shielding member 2 includes an upper shielding member 21 and a lower shielding member 22 separately formed. The upper shielding member 21 is provided above the upper insulating base 11 and is insert-molded with the upper insulating base 11. The lower shielding member 22 is provided below the lower insulating base 12 and is insert-molded with the lower insulating base 12.

[0062] As shown in FIG. 8 and FIG. 10, the insulating layer 3 is an integral structure, and wraps outside the upper shielding member 21 and the lower shielding member 22.

[0063] As shown in FIG. 9 and FIG. 11, the power supply body 41 is cylindrical shaped, and the signal bodies 42 and the grounding body 43 are flat shaped. A diameter D1 of each power supply body 41 is equal to a width D2 of each signal body 42 in the X-axis direction, and is less than a width D3 of the grounding body 43 in the X-axis direction. A distance between the power supply body 41 and an adjacent signal body 42 is d1, a distance between the two signal bodies 42 forming the differential pair is d2, and a distance between the grounding body and an adjacent signal body 42 is d3, where the distance d1, the distance d2 and the distance d3 are all equal.

[0064] As shown in FIG. 9 and FIG. 11, the insulator 5 wraps outside the power supply body 41 and is tubular shaped, and the shielding layer 6 wraps outside the insulator 5 and is tubular shaped. The shielding layer 6 respectfully abuts the upper shielding member 21 and the lower shielding member 22.

[0065] As shown in FIG. 8, FIG. 9 and FIG. 11, the grounding body 43 passes beyond the upper insulating base 11 and the lower insulating base 12 in the X-axis direction. The upper shielding member 21 bends downward and extends toward the grounding body 43, and the lower shielding member 22 bends upward and extends toward the grounding body 43. The upper shielding member 21 and the lower shielding member 22 respectively abut the grounding body 43 so as to form a contact region Z. The insulating layer 3 includes a first portion 33 and a second portion 34. The first portion 33 covers the upper insulating base 11 and the lower insulating base 12 in the Z-axis direction, and the second portion 34 covers the contact region Z in the Z-axis direction. A size S1 of the first portion 33 in the Z-axis direction is greater than a size S2 of the second portion 34 in the Z-axis direction.

[0066] To sum up, the electrical component according to certain embodiments of the present invention has the following beneficial effects:

[0067] (1) In certain embodiments of the present invention, by providing a shielding layer 6 and an insulator 5 provided between the power supply body 41 and the shielding layer 6 outside the power supply body 41, shielding of the shielding layer 6 from the power supply body 41 is implemented, so as to reduce an interference of the power supply body 41 on a signal body 42, thereby improving transmission quality of high-frequency signals. Further, compared with providing the shielding structure outside the signal bodies 42 in the related art, by providing the shielding layer 6 outside the power supply body 41, production costs of the insulator 5 and the shielding layer 6 are greatly reduced.

[0068] (2) The grounding body 43 and the shielding layer 6 are respectively in contact with the upper shielding member 21 and the lower shielding member 22, thereby forming a shielding space wrapping outside the signal bodies 42 constituting a differential pair, so as to separate the signal bodies 42 from outside environment, such that the interference to signal transmission of the signal bodies 42 is reduced, and the signal quality thereof is better.

[0069] (3) By conductively connecting the shielding layer 6 and the shielding member 2, complete separation of the power supply body 41 from the signal bodies 42 on both left and right sides can be implemented, such that signal transmission interference of the signal bodies 42 is reduced and the signal quality thereof is better.

[0070] (4) By providing a shielding layer 6 and an insulator 5 provided between the power supply body 41 and the shielding layer 6 outside the power supply body 41, the insulator 5 completely wraps the power supply body 41, and the shielding layer 6 completely wraps the insulator 5, the interference of the power supply body 41 on the signal bodies 42 is reduced in a great extent, and the signal transmission quality thereof is improved.

[0071] (5) The power supply body 41 is cylindrical shaped, and the diameter of the power supply body 41 is much less than the width of the signal body 42 or the grounding body 43 in the X-axis direction, such that the distance d1 between the cylindrical power supply body 41 and the flat signal body 42 is increased, thereby reducing the interference of the power supply body 41 on the signal bodies 42 and improving the transmission quality of the high-frequency signals.

[0072] (6) Each of the protruding blocks 111 downward abuts a middle portion of the corresponding signal body 42. Two adjacent ones of the protrusions 122 upward abut two opposite sides of the corresponding one of the signal bodies 42. Each slot 123 is located right below a corresponding protruding block 111, and each slot 123 is larger than the corresponding protruding block 111, such that the signal bodies 42 can be fixed to the insulating base 1 through very small portions, ensuring that a large portion of each signal body 42 is in contact with air and transmits signals through the air. Compared to the conventional electrical component 100 transmits signals through plastic portions, the structure has a super low signal attenuation effect.

[0073] The foregoing description of the exemplary embodiments of the invention has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed.
