The terminal subassemblies 50 are configured for connection with the tray 40 and/or the flat cable 60. The tray 40 includes one or more slots 70 (e.g., slots 70A-70G) and/or a cavity 72. The cable 60 includes one or more electrical conductors 78 (e.g., conductors 78A-78G) that have exposed portions 80 (e.g., exposed portions 80A-80G).
FIG. 1 shows a terminal subassembly 50 including a first terminal 90 connected to a first end 92A of a subassembly conductor 94 and a second terminal 96 connected to a second end 94B of the subassembly conductor 94. The first terminal 90 is electrically connected to the second terminal 96 via the subassembly conductor 94. In an assembled configuration, the tray 40 is partially disposed within the housing 30. A portion of the cable 60 is disposed in the cavity 72 of the tray 40. A first portion of a terminal subassembly 50 is disposed in a slot 70 of the tray 40 and a second portion of the terminal subassembly 50 is disposed in the cavity 72 of the tray 40 (see, e.g., FIGS. 13 and 14). A second terminal 96 of a terminal subassembly 50 is electrically connected to an exposed conductor portion 80 of the cable 60. The assembly 20 is shown including seven terminal subassemblies 50, slots 70, and conductors 78, however the assembly 20 may include more or less than seven terminal subassemblies 50, slots 70, and/or conductors 78.
FIGS. 3 and 4 illustrate a housing 30 (e.g., an electrical connector housing) including a body 100 and a cover 102 extending from the body 100. In some implementations, the cover 102 is pivotally connected to the body 100. The cover 102 includes a planar first portion 104A and a planar second portion 104B offset from the planar first portion 104A. Referring now to FIGS. 2 and 15, the body 100 is configured to receive a first portion 74A of the tray 40 and the cover 102 is configured to connect with a second portion 74B of the tray 40. In a latched/assembled configuration, the cover 102 and the tray 40 apply a force to portions of the terminal subassemblies 50 (e.g., the second terminals 96) and a portion of the cable 60 in a direction 106 (e.g., perpendicular to the portion of the cable 60 disposed in the tray 40, parallel to the Z-axis) such that the cable 60 is restricted from moving relative to the housing 30 and/or the tray 40.
FIGS. 5-7 illustrate a tray 40 formed separately from the housing 30. The tray 40 includes a plurality of slots 70 (e.g., slots 70A-70G) that end at a cavity 72. The slots 70 are disposed in a first portion 74A of tray 40 and/or the cavity 72 is disposed in a second portion 74B of the tray 40. The slots 70 are disposed parallel to one another (e.g., parallel to the X-axis). The slots 70 may be defined by walls 68 that are parallel to an X-Z plane. The slots 70 extend from a first end 76A of the tray 40 and terminate before a second end 76B of the tray 40. Optionally, each slot 70 includes a projection 110. A projection 110 is configured to restrict a portion of the terminal subassembly 50 (e.g., a first terminal 90) from moving relative to the tray 40. The tray 40 includes a protrusion 112 disposed within the cavity 72. The protrusion 112 extends upward and is perpendicular to the slots 70 (e.g., parallel to the Y-axis). Referring now to FIGS. 2 and 15, in a latched/assembled configuration, the cover 102 of the housing 30 is engaged with the tray 40 such that the cover 102 restricts removal of the tray 40 from the housing 30. The cover 102 is latched with the tray 40 such that a portion of the cable 60 is disposed between the cover 102 and the protrusion 112. The cover 102 applies a force to portions of the terminal subassemblies 50 (e.g., the second terminals 96) and the portion of the cable 60, and the force is perpendicular to the portion of the cable 60 disposed in the cavity 72.
FIG. 10 illustrates a subassembly conductor 94 (e.g., a flexible FFC trace connection) including an intermediate portion 130, a first planar portion 132A, and/or a second planar portion 132B. The intermediate portion 130 is non-planar in some configurations may be disposed between the first planar portion 132A and the second planar portion 132B. The first planar portion 132A and the second planar portion 132B are offset from each other in the Y-direction) The conductor 94 may include a rectangular cross-section. The conductor 94 is configured for connection with a first terminal 90 and/or a second terminal 96.
FIGS. 8 and 11 illustrate a first terminal 90 of a terminal subassembly 50, the first terminal 90 including a planar base 120 and a connector 122. The base 120 is connected with a first end 92A of the subassembly conductor 94 (e.g., the first planar portion 132A). For example and without limitation, the base 120 may be fixed with the conductor 94, such as via welding (e.g., laser welding, ultrasonic welding, etc.). The connector 122 may be configured for connection with an external object. For instance, the connector 122 may include prongs/arms that receive a terminal of an external electrical connector that connects with the housing 30.
FIGS. 9 and 12 illustrate a second terminal 96 of a terminal subassembly 50, the second terminal 96 including a planar base 140, a tab 142 extending from the base 140, and a projection 144 extending from the base 140. The tab 142 is disposed proximate a first end 146A of the second terminal 96 and the projection 144 is disposed proximate a second end 146B of the second terminal 96. The tab 142 is disposed perpendicular to the projection 144 and the planar base 140. The tab 142 is connected with a second end 92B of the subassembly conductor 94 (e.g., the second planar portion 132B). For example and without limitation, the tab 142 may be fixed with the conductor 94 via welding (e.g., laser welding, ultrasonic welding, etc.).
With reference to FIGS. 13 and 14, a flat cable 60 includes an elongated body 160 having one or more electrical conductors 78 and/or an insulating material 162 that electrically insulates the conductors and/or the conductors 78 from each other and/or other components. The electrical conductors 78 include exposed portions 80 that are not completely covered by insulating material 162 and/or from which insulating material 162 has been removed. The one or more conductors 78 and exposed portions 80 may be disposed in parallel with each other and/or may be substantially aligned with a common plane. The one or more conductors 78 may, in some configurations, be integrally formed with the insulating material 162. The conductor portions 80 may have varying sized widths.
Referring now to FIG. 13, in some example configurations, a cable 60 may include conductors 78 and (and corresponding exposed conductor portions 80) that have the same or different widths. For example, the cable 60 may include a first exposed conductor portion 80A having a first width 80AW, a second exposed conductor portion 80B having a second width 80BW, a third exposed conductor portion 80C having a third width 80CW, a fourth exposed conductor portion 80D having a fourth width 80DW, and/or a fifth exposed conductor portion 80E having a first width 80EW. In some examples, a least one of the exposed conductor portions 80 may include a width that is different than the others. For example and without limitation, the fourth exposed conductor portion 80D is shown having a width 80DW that is greater than widths 80AW-80CW, 80EW of the other exposed conductor portions 80A-80C, 80E and/or the third exposed conductor portion 80C is shown having a width 80CW greater than widths 80AW, 80BW of the first and second exposed conductor portions 80A, 80B but less than a width 30DW of the fourth exposed conductor portion 80D.
Referring now to FIG. 14, in some implementations, a cable 60 may include a first exposed conductor portions 80A having a first width 80AW, a second exposed conductor portion 80B having a second width 80BW, and/or a third exposed conductor portion 80C having a third width 80CW. The first width 80AW may be different from the second width 80BW and/or the third width 80CW. In some instances, the first width 80AW may be the same as the second width 80BW and/or the third width 80W.
With continued reference to FIG. 14, an electrical assembly 20 is configured to be utilized with flat cables 60 including varying numbers of conductors 78 and exposed portions 80, and/or conductors 78 and exposed portions 80 having varying sized widths. For example, the same configuration of a housing 30 and a tray 40 may be used for a variety of configurations of cables 60, conductors 78, and/or exposed portions 80.
In some configurations, an assembly 20 includes a terminal subassembly 50 electrically connected to each exposed conductor portion 80 of a cable 60. The number of subassemblies 50 corresponds to the number of conductor portions 80. For example and without limitation, an electrical assembly 20 may include a first subassembly 50A electrically connected to a first exposed conductor portion 80A, a second subassembly 50B electrically connected to a second exposed conductor portion 80B, and/or a third subassembly 50C electrically connected to a third exposed conductor portion 80C. A second terminal 96A of the first subassembly 50A may be connected to the first exposed conductor portion 80A, a second terminal 96B of the second subassembly 50B may be connected to the second exposed conductor portion 80B, and/or a second terminal 96C of third subassembly 50C may be connected to the third exposed conductor portion 80C. In some examples, a second terminal 96 may be welded (e.g., via laser welding, ultrasonic welding, etc.) to an exposed conductor portion 80.
In an assembled configuration, a first planar portion 132A of a subassembly conductor 94 may be offset in a lateral direction (e.g., parallel to the Y-axis) and/or a longitudinal direction (e.g., parallel to the X-axis) from a second planar portion 132B of the subassembly conductor 94. In some examples, one or more center lines of the exposed conductor portions 80 may be aligned with center lines of second terminals 96 in the lateral direction (see center lines 80BCL, 96BCL of exposed conductor portion 80 and second terminal 96B). Additionally or alternatively, one more of the center lines of the exposed conductor portions 80 and the second terminals 96 may be offset relative to a center line (e.g., 90BCL) of a first terminal (e.g., 90B) in the lateral direction (see, e.g., center line 90BCL of first terminal 90 offset from center lines 80BCL, 96BCL). A subassembly conductor 94 is disposed perpendicular to a portion of the flat cable 60 disposed in the cavity 72 of the tray 40 (see, e.g., FIG. 15). A subassembly conductor 94 may be curved, bent, and/or angled according to an offset between first and second terminals 90, 96. The subassembly conductor(s) 94 may be disposed in a non-parallel manner relative to the X-direction and/or may be perpendicular to an X-Y plane. The length of a subassembly conductor 94 may correspond to the offset between first and second terminals 90, 96 (e.g., greater lengths for greater offsets). An electrical assembly 20 may include subassembly conductors 94 of different lengths, such as if a cable includes conductors 78 of different widths.
In some implementations, the first planar portions 132A (e.g., first planar portions 132A-132A″) of the respective subassembly assembly conductors 94 are offset relative to the second planar portions 132B (e.g., second planar portions 132B-132B″) in the lateral direction and the longitudinal direction. In some examples, the planar portions 132A, 132B of at least two subassembly conductors 94 may be offset in the lateral direction by different offset distances. For example and without limitation, planar portions 132A, 132B of the first subassembly conductor 94A may be offset by a greater distance than planar portions 132A″, 132B″ of the third subassembly conductor 94C. Terminal subassemblies with greater offsets may include longer subassembly conductors 94 (e.g., subassembly conductors 94 may have different lengths). The offsets of the planar portions 132A, 132B allow the assembly 20 to compensate for exposed conductor portions 80 having different sized widths 80W.
FIGS. 16-18 present a method of assembling an electrical assembly 20. The method includes connecting a first end 92A of a subassembly conductor 94 (e.g., first planar portion 132A) to a base 120 of a first terminal 90 (see, e.g., FIG. 11) and/or connecting a second end 92B of the conductor 94 (e.g., second planar portion 132B) to a tab 142 of a second terminal 96 (see, e.g., FIG. 12) to produce a terminal subassembly 50. In some examples, the method includes connecting a terminal subassembly 50 to an exposed conductor portion 80 of a flat cable 60. The number of subassemblies 50 of the assembly 20 may correspond to the number of exposed conductor portions 80. In some example configurations, a base 140 of each second terminal 96 of a subassembly 50 is connected (e.g., welded) to an exposed conductor portion 80.
Referring now to FIG. 16, the method includes inserting the first terminals 90 (e.g., first terminals 90A-90G) of the subassemblies 50 (e.g., subassemblies 50A-50G) into respective slots 70 (e.g., slots 70A-70G) of a tray 40. The method includes inserting the second terminals 96 (e.g., second terminals 96A-96G) and/or a portion of the cable 60 into a cavity 72 of the tray 40. Referring now to FIG. 17, the method includes inserting the tray 40 into a housing 30. Referring now to FIG. 18, the method includes rotating a cover 102 of the housing 30 to latch the housing 30 with the tray 40. In some implementations, rotating the cover 102 to latch the housing 30 with the tray 40 includes pressing the second terminals 96 and the exposed conductor portions 80 between the cover 102 and a protrusion 112 of the tray 40 to restrict movement of the flat cable 60 relative to the tray 40.
