DETAILED DESCRIPTION
Reference will now be made in detail to embodiments of the present disclosure, examples of which are described herein and illustrated in the accompanying drawings. While the disclosure will be described in conjunction with embodiments, it will be understood that they are not intended to limit the disclosure to these embodiments. On the contrary, the disclosure is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the disclosure as defined by appended claims.
Referring to the drawings FIGS. 1A-1E generally illustrate an embodiment of a power distribution box (PDB) 10 that may be configured for high current (for example, up and/or exceeding 60 amps) applications. Power distribution box 10 may include a housing 12 and/or may be used to support a plurality of electrical components 40N, such as, for example only, electrical components within a portion of a vehicle. Housing 12 may include a first portion 12A and/or a second portion 12B. It should be appreciated, however, that power distribution box 10 may be used in any appropriate environment and for any suitable purpose.
In embodiments, such as generally illustrated in FIGS. 1A-3, PDB 10 may include a circuit board 20 and/or one or more electrical components 40N. In embodiments, circuit board 20 may comprise a printed circuit board (PCB). In embodiments, electrical components 40N may be attaches and/or electrically connected to circuit board 20.
In embodiments, an electrical component 40N may include one or more of fuses, relays, and/or other electrical components. In embodiments, one or more of electrical components 40N may include one or more terminals (e.g., terminals 42N, 44N). Terminals 42N, 44N may be configured for electrically connecting an electrical component 40N to circuit board 20, to another electrical component 40N, and/or to an electrical connector 60. Electrical connector 60 may be referred to herein as wiring harness connector 60, but is not limited to a wiring harness connector.
In embodiments, electrical components 40N may include a first terminal 42N and/or a second terminal 44N. In embodiments, first terminals 42N may be configured to contact circuit board 20 (e.g., make an electrical connection with an electrical trace 50), but may not extend through circuit board 20 and/or may not directly connect with electrical connector 60 (see also, e.g., FIG. 8).
In embodiments, a second terminal 44N of an electrical component 40N may or may not include a substantially similar configuration (e.g., length, width, thickness, etc.) as the first terminal 42N of the electrical component 40N. Second terminals 44N may be configured for insertion into and/or through circuit board 20, which may include having widths 44AN that may correspond to a corresponding aperture 22N in circuit board. For example, and without limitation, width 44A1 of a second terminal 441 may be about the same as corresponding aperture 221 and/or second terminal 441 may be press fit into corresponding aperture 221. In embodiments, second terminal 441 may be configured to extend through circuit board 20 and/or to connect directly to electrical connector 60. For example, and without limitation, some or all of second terminals 44N may be longer than first terminals 42N such that first terminals 42N extend through circuit board 20 sufficiently far to be soldered to circuit board 20 while second terminals 44 extend through circuit board 20 and into electric connector 60 (e.g., first terminal 421 may be shorter than second terminal 441 of electrical component 401).
In embodiments, such as generally illustrated in FIG. 3, electrical traces 50 may be connected to and/or disposed on circuit board 20. Electrical traces 50 may electrically connect electrical components 40N, which may be attached to circuit board 20, to each other and/or to other electrical components that may not be attached to circuit board 20. For example, and without limitation, electrical components 40N attached to circuit board 20 may be electrically connected to an electronic control unit (ECU) 70, which may or may not be physically connected or attached to circuit board 20, via electrical traces 50.
In embodiments, it may be desirable to minimize a total amount (e.g., number, length, volume, etc.) of electrical traces 50 on a circuit board 20. A reduced amount of electrical traces 50 may, in some instances, reduce the complexity and/or cost of manufacturing circuit board 20 and/or PDB 10. In embodiments, minimizing a total amount of electrical traces 50 may include determining an arrangement/layout of electrical components 40N on circuit board 20 that minimizes electrical traces 50. In embodiments, a minimized arrangement may include the smallest length, volume, and/or number of traces that still provides desired electrical connections between electrical components 40N. Determining an minimized arrangement may include determining a desired set of electrical components 40N for attaching to circuit board 20 and/or for connecting to a wiring harness connector 60. A desired set of electrical components 40N may include, among other things, fuses and/or relays that may have one or more of a variety shapes, sizes, configurations, and/or electrical characteristics (e.g., current ratings). For example, and without limitation, fuses may include current ratings from 5 amps to 60 amps.
In embodiments, determining a trace minimizing arrangement may, additionally or alternatively, include determining a surface area (e.g., a maximum surface area) of a face/side 24 of circuit board 20 to which electrical components 40N of the desired set may be connected or attached. A minimizing arrangement may be determined according to the desired set of desired electrical components 40N and the surface area of circuit board 20, and/or a list of desired electrical connections. A list of intended or desired connections may specify how electrical components 40N should be connected (e.g., to which other electrical component(s) 40N). For example, and without limitation, electrical components 40N of the desired set may be iteratively arranged relative to the determined surface area and the list of desired electrical connections, and the iteration/arrangement with the lowest total amount of electrical traces 50 may be designated as the minimizing arrangement. In embodiments, iteratively arranging the electrical components 40N may be conducted via a simulation, such as a computer simulation. A simulation may include models of circuit board 20, electrical components 40N, electrical traces 50, and/or electrical connector 60. A computer simulation may be configured to automatically iterate through all possible arrangements, compare the total amount of electrical traces 50 from each arrangement, and/or select a preferred or optimized arrangement (e.g., the arrangement with the lowest total amount of electrical traces 50).
In embodiments, one or more of electrical terminals 40N may include a long side/dimension 40AN and a short side/dimension 40BN. Long side 40AN may be the longest side of an electrical terminal 40N and short side 40BN may be the shortest side of an electrical terminal 40N. As generally illustrated in FIG. 2C, circuit board 20 may include long edges 26A, 26B and short edges 28A, 28B (e.g., the lengths of edges 26A, 26B may be longer than the lengths of edges 28A, 28B). In embodiments, a minimized tor optimized) arrangement may include a first set of electrical components 40N (e.g., components 401-4019, 4021-4024, 4027-4030, 4032-4050) and/or a second set of electrical components (e.g., components 4020, 4025, 4026, 4031). A minimized arrangement may include the first set of electrical components 40N being, disposed such that the long side 40A20 of each electrical component of the first set is parallel with long edges 26A, 26B of circuit board 20. In embodiments, the second set of electrical components 40N may include a long side 40AN (e.g., long sides 40A20, 40A25, 40A26, 40A31) and a short side 40BN (e.g., short sides 40B20, 40B25, 40B26, 40B31). A minimized arrangement may include the second set of electrical components 40N being disposed such that the long side 40AN of each electrical component of the second set is parallel with short edges 28A, 28B of circuit board 20 and/or perpendicular to long edges 26A, 26B of circuit board 20.
In embodiments, such as generally illustrated in FIGS. 1B-4A, a minimized arrangement may include disposing electrical components 40N in a plurality of rows RN (e.g., rows R1, R2, R3, R4, R5, R6, R7, R8) and/or in a plurality of columns. In embodiments, a row of electrical components 40N may include one or more electrical components 40N from the first set and/or one or more electrical components from the second set (e.g., a row may include electrical components 40N disposed perpendicularly to each other). For example, and without limitation, at least one of the plurality of rows RN may include at least two electrical components 40N from the first set and at least two electrical components 40N from the second set. In embodiments, each row RN or column may or may not include the same number of electrical components 40N. For example, and without limitation, a first group of rows RN may include a first number of electrical components (e.g., rows R2, R3, R6, and R7 may include seven electrical components, such as generally illustrated in FIGS. 1-5). In embodiments, a second group of rows RN may include a second number of electrical components 40N that may be different than the first number (e.g., rows R1 and R8 may include five electrical components, such as generally illustrated in FIGS. 1-3). In embodiments, a minimized arrangement may include the first and second groups of rows RN with different numbers of electrical components in each group of rows RN. In embodiments, such as generally illustrated in FIGS. 1B-4A, a minimized arrangement may include more than two groups of rows RN that each include the same number of electrical components. In embodiments, a minimized arrangement may include three or more groups, each row in a particular group may include the same number of electrical components, and/or rows from different groups may have different numbers of electrical components per row.
In embodiments, the plurality of rows RN may include at least eight rows (e.g., rows R1-R8). In embodiments, some rows (e.g., rows R1 and R8) may be disposed at opposite ends of circuit board 20. Some rows (e.g., rows R1 and R8) may include a plurality of large electrical components and/or a plurality of small electrical components. In embodiments, large electrical components may include time-delay fuses and/or fuses configured for temporary and/inrush current, such as, for example, MCASETM fuses offered by Littlefuse, Inc. In embodiments, small electrical components may include, for example, micro fuses. In embodiments, small electrical components may be physically smaller (e.g., length, width, and/or height) than large electrical components. In embodiments, certain rows (e.g., rows R1 and R8) may each include a total of five electrical components. In embodiments, certain rows (e.g., row R1) may include electrical components 401-405, which may all be large electrical components. In embodiments, certain rows (e.g., row R8) may include three small electrical components (e.g., components 4046, 4048, 4050) and two large electrical components (e.g., components 4047, 4049), and/or the electrical components 40N may be disposed in an alternating pattern according to size (e.g., small, large, small, large, small). In embodiments, such as generally illustrated in FIG. 2B, an alternating pattern may include large electrical components (e.g., components 4047 and 4049) being disposed at relatively small distances from adjacent small electrical components (e.g., component 4046, 4048, and/or 4050). For example, and without limitation, a center-to-center distance 56 between components 4046 and 4047 (e.g., between respective center lines) may be about 8.30 mm or less.
In embodiments, a group of rows (e.g., rows R2, R3, R6, and R7) may be disposed between rows from a different group or different groups (e.g., between R1 and R8). Certain rows (e.g., rows R2, R3, R6, and R7) may each include a plurality of small electrical components (e.g., components 406-4019 and 4032-4045) that may or may not be disposed at equal distances from each other. In embodiments, such as generally illustrated in FIG. 2B, certain small electrical components (e.g., two or more adjacent components of components 406-4019 and/or components 4032-4045) may be disposed at a relatively small distance from each other. For example, and without limitation, a distance 52 between center lines of components 406 and 407 may be about 5.50 mm or less.
In embodiments, second terminals (e.g., terminals 446, 447, 448, 449, 4410, 4411, 4412) of electrical components in row R2 may be disposed such that they face a corresponding first terminal (e.g., terminals 4213, 4214, 4215, 4216, 4217, 4218, 4219) of an electrical component in row R3. In embodiments, first terminals of components in one or more of the rows RN may be disposed such that they are disposed outward of second terminals 44N, relative to the center of circuit board 20. In embodiments, second terminals 44N (e.g., terminals 4432, 4433, 4434, 4435, 4436, 4437, 4438) of electrical components 40N in certain rows (e.g., components 4032-4038 of row R6) may be disposed such that they face corresponding first terminals 42N (e.g., terminals 4239, 4240, 4241, 4242, 4243, 4244, 4245) of electrical components in an adjacent row (e.g., components 4039-4045 of row R7). In embodiments, first terminals 42N of components in certain rows (e.g., rows R6 and R7) may be disposed such that they are disposed outward of their respective second terminals 44N.
In embodiments, a group of rows (e.g., rows R4 and R5) may be disposed at or near the middle of circuit board 20, which may include being disposed in the middle of rows R2, R3, R6, and R7 and/or directly between rows R3 and R6. In embodiments, rows R4 and R5 may both be configured with the same or similar electrical component arrangement. Certain rows (e.g., row R4 and/or row R5), which may be disposed adjacent to each other, may include a plurality of large electrical components (e.g., components 4020, 4021, 4024-4027, 4030, 4031) and a plurality of small electrical components (e.g., components 4022, 4023, 4028, 4029). In embodiments, large electrical components may be disposed at opposite sides of circuit board 20 and small electrical components may be disposed between the large electrical components.
In embodiments, such as generally illustrated in FIGS. 2A and 2C, a first set of large electrical components (e.g., components 4020, 4025, 4026, 4031) may be disposed at or near edges of circuit board (e.g., edges 26A, 26B, 28A, 28B). In embodiments, longitudinal axes 44L20, 44L25, 44L26, 44L31, 44L31 of second terminals 4420, 4425, 4426, 4431 of the first set of large electrical components may be disposed parallel to long edge 26 of circuit board 20.
In embodiments, such as generally illustrated in FIG. 2B, certain large electrical components (e.g., components 4020 and 4026) may be disposed at a relatively small distance from each other. For example, and without limitation, a distance 54 between center lines of components 4020 and 4026 (and/or between components 4025 and 4031) may be about 11.20 mm or less.
In embodiments, a second set of large electrical components e.g., components 4021, 4024, 4027, 4030) may be disposed adjacent to and/or inside of the first set of electrical components. Longitudinal axes 44L21, 44L24, 44L27, 44L30 of second terminals 4421, 4424, 4427, 4430 of the second set of electrical components may be disposed perpendicular to long edge 26 of circuit board 20, which may include being disposed generally perpendicular to second terminals 4420, 4425, 4426, 4431 of the first set of large electrical components. In embodiments, the first set of large electrical components may be disposed perpendicular to the second set of large electrical components (e.g., long side 40A20 of component 4020 may be perpendicular to long side 40A21 of component 4021).
In embodiments, longitudinal axes 44LN (e.g., axes 44L6, 44L7, 44L8 44L9, 44L10, 44L11, 44L12) of second terminals 44N of some or all small electrical components 40N may be disposed perpendicular to long edge 26 of circuit board 20.
In embodiments, one or more rows (e.g., row R4) may include small electrical components 4022, 4023 disposed between large electrical components 4021, 4024, which may be disposed between large electrical components 4020, 4025. In embodiments, row R5 may include small electrical components 4028, 4029 disposed between large electrical components 4027, 4030, which may be disposed between large electrical components 4026, 4031. In embodiments, such as generally illustrated in FIGS. 1 and 3, one or more electrical components 40N may be disposed such that at least a portion of each may extend beyond an outer perimeter of circuit board 20, which may include at least a portion of first terminal 42N of the electrical component being disposed outside the perimeter of circuit board 20, and a second terminal 44N disposed through an aperture 22N in circuit board 20 (e.g., for connection with electrical connector 60). For example, and without limitation, each electrical component 40N in rows R1 and R8 may be disposed such that first terminals 421, 422, 423, 424, 425 of components 401, 402, 403, 404, 405, and/or first terminals 4246, 4247, 4248, 4249, 4250 of components 4046, 4047, 4048, 4049, 4050 may be disposed entirely outside the perimeter of circuit board 20. In embodiments, first terminals 4220, 4225, 4226, 4231 of components 4020, 4025, 4026, 4031 may be disposed at least partially outside the perimeter of circuit board.
An arrangement that includes electrical components 40N disposed perpendicularly to each other, particularly within the same row and/or column, may be somewhat counterintuitive with respect to conventional designs (see, e.g., conventional design 100 in FIG. 9). For example, and without limitation, disposing electrical components 40N perpendicular to each other (e.g., with respective terminals 42N, 44N perpendicular to each other) may typically be assumed to increase a minimum surface area of circuit board 20, which could be considered undesirable. However, such an arrangement may reduce an amount of electrical traces 50 for connecting the electrical components 40N, and/or the benefits of such reduction may limit and/or outweigh undesirable effects (e.g., increased surface area), if any. For example, and without limitation, reducing an amount of traces 50 may reduce costs, complexity, and/or may reduce a minimum surface area of circuit board 20 to accommodate electrical components 40N and traces 50.
In embodiments, after circuit board 20 has been designed (e.g., with a trace minimizing electrical component 40N arrangement) and/or assembled, a wiring harness connector 60 may be designed and/or manufactured. In embodiments, such as generally illustrated in FIGS. 4B-7, a wiring harness connector 60 may include a housing 66. In embodiments, wiring harness connector 60 may be manufactured to include one or more connector terminals 62N that may be configured for electrical connection with first terminals 42N and/or second terminals 44N of electrical components 40N. An arrangement of connector terminals 62N may generally correspond to (e.g., may be a mirror image of) some or all of a trace minimizing electrical component arrangement, which may include being arranged in a plurality of rows CRN. For example, and without limitation, connector rows CR1, CR2, CR3, CR4, CR5, CR6, CR7, CR8 and the electrical terminals therein (e.g., terminals 621-6250) may correspond to and/or be configured for electrical connection with electrical components 401-4050 in rows R1, R2, R3, R4, R5, R6, R7, R8 of circuit board 20 and the second terminals 44N thereof (e.g., second terminals 441-4450), respectively.
In embodiments, at least one connector terminal (e.g., terminal 64) may be configured for an electrical connection with an electrical component that is not attached to circuit board 20 and/or that is not part of a trace minimizing electrical component arrangement. In embodiments, such an electrical component that is not attached to circuit board 20 and/or that is not part of a trace minimizing electrical component arrangement may include a power source, such as, for example, a vehicle battery 80.
In embodiments, a method of manufacturing an electrical connector 60 may comprise determining a footprint (e.g., physical dimensions) and/or layout of a conventional circuit board, which may include determining a conventional total amount of traces 50 that electrically connect a plurality of electrical components 40N. The method may include determining a circuit board layout that minimizes a total amount of electrical traces 50. The minimized amount of traces 50 may be determined according to the same circuit board footprint as the conventional circuit board and the minimized amount be less than the conventional total amount of traces (e.g., a lesser total amount of traces for the same size circuit board or, potentially, a smaller circuit board). The method may include designing a layout for terminals of the electrical connector 60 according to the determined circuit board layout and/or manufacturing, the electrical connector 60 according to the designed layout.
