[0019] To make the description of this disclosure more detailed and complete, reference may be made to the accompanying drawings and the various embodiments described below. The elements in the drawings are not drawn to scale and are provided for illustrative purposes only. Many practical details are described below to provide a comprehensive understanding of this disclosure; however, those skilled in the art will understand that this disclosure can be practiced without one or more of these practical details, and therefore, these details should not be used to limit this disclosure.

[0020] Please refer to Figure 1, which is an assembly diagram illustrating a power connector assembly 29 according to one embodiment of this disclosure. As shown, the power connector assembly 29 includes a board-end connector 30 and a wire-end connector 60. The board-end connector 30 is disposed on a circuit board 96, while the wire-end connector 60 is connected to one end of a cable assembly 97. The board-end connector 30 and the wire-end connector 60 can be interconnected for power transmission. In some embodiments, electronic components (not shown, such as chips) are disposed on the circuit board 96, and the electronic components are connected to the board-end connector 30 through conductive lines on or inside the surface of the circuit board 96. The other end of the cable assembly 97 is connected to a power source, which can supply power to the electronic components via the cable assembly 97, the power connector assembly 29, and the circuit board 96. The board-end connector 30 in this embodiment is a vertical type connector, which is disposed upright on the circuit board 96, and its mating direction K1 is substantially perpendicular to the circuit board 96. The power connector assembly 29 disclosed herein can be used in computer servers, but is not limited thereto.

[0021] Please refer to Figure 2, which is an exploded view of the power connector assembly 29 shown in Figure 1. As shown, the board-end connector 30 includes an insulating housing 31 and a plurality of terminals, each terminal including at least one detection terminal 32 and a plurality of power terminals 33. The insulating housing 31, detection terminals 32, and power terminals 33 are all fixedly mounted on a circuit board 96, and the detection terminals 32 and power terminals 33 are disposed within the insulating housing 31. The insulating housing 31 contains an insulating material, while the detection terminals 32 and power terminals 33 contain a conductive material, such as copper.

[0022] As shown in Figure 2, the wire-end connector 60 includes an insulating housing 61 and a plurality of wire-end terminals 63 disposed within the insulating housing 61 (see Figure 5). The wire-end terminals 63 contain a conductive material (e.g., copper) and are configured to contact and electrically connect to the detection terminals 32 and power terminals 33 of the board-end connector 30. The cable assembly 97 includes a plurality of cables, one end of which is electrically connected to the wire-end terminals 63 (e.g., the cables can be fixed to the wire-end terminals 63 by soldering) and extends from one side of the insulating housing 61. The wire-end connector 60 also includes an inner mold 62. The inner mold 62 is disposed within the insulating housing 61 and partially covers the wire-end terminals 63 and the cable assembly 97. The inner mold 62 positions the wire-end terminals 63 and the cable assembly 97 within the insulating housing 61 and ensures a secure connection between the wire-end terminals 63 and the cable assembly 97 (e.g., protecting the solder joints of the wire-end terminals 63 and the cable assembly 97). The inner mold 62 contains insulating material and can be formed by injection molding.

[0023] As shown in Figure 2, the insulating housing 61 of the wire connector 60 includes a body 65 and two latches 66 disposed on both sides of the body 65. In this embodiment, the two latches 66 are located on opposite long sides of the body 65. The latches 66 are rotatably mounted on the body 65 via a pivot structure 663 and are configured to engage and fix with the insulating housing 31 of the board connector 30 to ensure a secure connection between the board connector 30 and the wire connector 60. The insulating housing 61 has a groove corresponding to the position of the latch 66. The groove's appearance matches part or all of the structure of the latch 66 to accommodate part or all of the latch 66. Each latch 66 may also include an operating part 661 and a latching part 662, located on both sides of the pivot structure 663. The outer surface of the latching part 662 is flush with or lower than the outer surface of the insulating housing 61. The latching part 662 is configured to engage and secure with the insulating housing 31 of the board-end connector 30. The operating part 661 can be pressed by a user; when pressed, the latching part 662 separates from the insulating housing 31 of the board-end connector 30, allowing the wire-end connector 60 to be separated from the board-end connector 30. The outer surface of the operating part 661 is flush with or higher than the outer surface of the insulating housing 61. Therefore, by providing a groove in the insulating housing 61 corresponding to the latch 66, the outward protrusion height of the latch 66 can be reduced, thus reducing the overall size of the wire-end connector 60.

[0024] As shown in Figure 2, in some embodiments, the body 65 of the insulating housing 61 of the wire terminal connector 60 has two side openings 67 (see also Figure 6). The side openings 67 are located on opposite sides of the wire terminal 63, and two latches 66 are respectively disposed facing the side openings 67. In some embodiments, the body 65 also includes two baffles 68, each baffle 68 partially shielding the corresponding side opening 67 and latches 66, thus protecting the latches 66 and preventing dust. The two baffles 68 protrude slightly outward, and the maximum distance between the outermost edges of the two baffles 68 (i.e., the widest distance of the wire terminal connector 60 in the third direction K3) is equal to or greater than 10 mm, preferably equal to or greater than 15 mm.

[0025] As shown in Figure 2, in some embodiments, the wire connector 60 further includes an unlocking device 69 configured to connect the two latches 66. The unlocking device 69 includes a pull strap 691 and a connector 692. The connector 692 extends across both sides of the body 65, and its two ends are respectively connected to the operating portions 661 of the two latches 66. The pull strap 691 is connected to the connector 692 and is positioned at the middle of the connector 692. The pull strap 691 can be pulled by a user, and pulling the pull strap 691 achieves the same effect as pressing the operating portions 661 of the latches 66, allowing the wire connector 60 to separate from the board connector 30. In some embodiments, the connector 692 may have a curved shape. In some embodiments, the connector 692 may be a flexible plastic part.

[0026] As shown in Figure 2, the insulating housing 31 of the board-end connector 30 includes a base 35 and a mating portion 36. The base 35 is located on the side of the board-end connector 30 closest to the circuit board 96. The mating portion 36 is located on the side of the board-end connector 30 furthest from the circuit board 96, and the mating portion 36 extends into the wire-end connector 60 when the board-end connector 30 is connected to the wire-end connector 60.

[0027] As shown in Figure 2, in some embodiments, the base 35 of the insulating housing 31 includes two wings 37, which are disposed on opposite sides of the base 35 and each is fixedly connected to the circuit board 96 via a fastener 38. The two wings 37 are protruding relative to the base 35; that is, the base 35 is located between the two wings 37. Simultaneously, in the second direction K2, the two wings 37 protrude outward relative to the joint 36. The fastener 38 is, for example, a metal sheet, which can hook onto the wings 37. In some embodiments, the base 35 of the insulating housing 31 has an opening 34, which is disposed adjacent to the circuit board 96 and exposes a portion of the detection terminal 32 and the power terminal 33 (see also Figure 1) to facilitate heat dissipation from the detection terminal 32 and the power terminal 33.

[0028] As shown in Figure 2, the joint 36 of the insulating housing 31 has a slot 39, which is located on opposite sides of the insulating housing 31 with the opening 34. The slot 39 is used to receive the wire terminal 63 of the wire connector 60. The detection terminal 32 and the power terminal 33 are partially exposed in the slot 39 to contact the wire terminal 63 of the wire connector 60. When the detection terminal 32 contacts the wire terminal 63, a detection signal is generated to represent the connection status or power supply status of the board connector 30 and the wire connector 60. The detection terminal 32 and at least one power terminal 33 contact the same wire terminal 63, so the generated signal can accurately reflect the actual connection status or power supply status. The slot 39 forms a top opening on the top surface of the insulating housing 31 (or joint 36) and two side openings on both sides of the insulating housing 31 (or joint 36). The top opening and the two side openings are interconnected, and the depths (lengths along the joint direction K1) of the two side openings are different. The top and side connections of the insulating housing 31 are chamfered. In other embodiments, the board-end connector 30 can also be connected to an edge card, the slot 39 can be used to receive the edge card, and the detection terminal 32 and power terminal 33 are configured to contact the electrical contacts of the edge card.

[0029] As shown in Figure 2, in some embodiments, the joint 36 of the insulating housing 31 includes at least one hook 43, and the latching portion 662 of at least one of the two latches 66 of the wire connector 60 is configured to engage with the hook 43. In this embodiment, the joint 36 of the insulating housing 31 includes two hooks 43 (see also Figure 4), the two hooks 43 are disposed on opposite sides of the joint 36, and are respectively engaged with the two latches 66 of the wire connector 60.

[0030] As shown in Figure 2, in some embodiments, the joint 36 of the insulating housing 31 further includes at least one guide bar 40, which is disposed on the side of the joint 36 and extends in the engagement direction K1 of the board-end connector 30 and the wire-end connector 60. In some embodiments, the joint 36 of the insulating housing 31 includes at least one first guide bar 41 and at least one second guide bar 42, wherein the first guide bar 41 and the second guide bar 42 are different in size and position, or have different size and position.

[0031] As shown in Figure 2, the detection terminals 32 and power terminals 33 of the board-end connector 30 are erected on the circuit board 96 and divided into two groups. The two groups of terminals are respectively disposed on both sides of the slot 39 of the insulating housing 31, forming two rows of terminals. Each group of terminals may include at least one set of power terminals, and each set of power terminals may include multiple power terminals; that is, the board-end connector 30 may include at least two sets of power terminals, disposed on both sides of the slot 39 of the insulating housing 31. The contact portions 332 (spring arms) of the multiple power terminals 33 in each set of power terminals are arranged in a row in the second direction K2. In this embodiment, each group of terminals includes one detection terminal 32 and four power terminals 33. Two power terminals 33 constitute a group. The detection terminal 32 and the two groups of power terminals 33 are arranged in the second direction K2, which is substantially perpendicular to the engagement direction K1, and the detection terminal 32 is disposed between the two groups of power terminals 33. The two groups of power terminals 33 may transmit the same or different voltages. In some embodiments, one group of the two sets of terminals includes the detection terminal 32, while the other group does not. That is, the detection terminal 32 is only provided on one side of the slot 39, and is configured to correspond to the line terminal 63 in the wire connector 60 that transmits positive voltage.

[0032] As shown in Figure 2, each power terminal 33 includes a pin portion 331, a contact portion 332, and an intermediate portion 333 connecting the pin portion 331 and the contact portion 332. The width of the intermediate portion 333 in the second direction K2 is greater than the width of both the pin portion 331 and the contact portion 332. The pin portion 331 extends beyond the insulating housing 31 for electrical connection with the circuit board 96. The pin portion 331 includes a plurality of tail ends that are inserted into and connected to the circuit board 96. The plurality of tail ends of each power terminal 33 are arranged in a pin row in the second direction K2. The contact portion 332 is exposed in the slot 39 and includes at least one spring arm. The intermediate portion 333 may include a limiting structure 334 through which the power terminal 33 can be engaged and fixed to the insulating housing 31. The limiting structure 334 may be, for example, a protrusion protruding from the side of the intermediate portion 333 or / and protrusions protruding from the left and right sides of the intermediate portion 333.

[0033] As shown in Figure 2, in this embodiment, the number of tail ends of the foot portion 331 is three, while the contact portion 332 includes a single cantilever. In other embodiments, the contact portion 332 may include multiple spring arms arranged in the second direction K2.

[0034] As shown in Figure 2, in this embodiment, each set of power terminals 33 includes power terminals 33P and 33Q. The pin portions 331 and intermediate portions 333 of power terminals 33P and 33Q are separated from each other in a third direction K3, which is substantially perpendicular to the engagement direction K1, or may be perpendicular to the second direction K2. That is, the arrangement direction of the contact portions 332 of each set of power terminals 33 is perpendicular to the arrangement direction of the intermediate portions 333. Power terminal 33P also has a bent portion 335, which is connected between the contact portion 332 and the intermediate portion 333. The notch of the bent portion 335 is away from the power terminal 33Q, such that the contact areas 336 of the contact portions 332 of power terminals 33P and 33Q (located on the spring arm and used to contact the wire terminal 63 of the wire connector 60) are substantially coplanar. In the mating direction K1, the contact areas 336 of the power terminals 33P and 33Q are positioned differently to reduce the force required for the wire-end connector 60 to connect to the board-end connector 30. In other words, the distance between the contact areas 336 of the two power terminals 33P and 33Q and the entrance of the slot 39 is different. Furthermore, the plurality of tail ends of the pins 331 of each set of power terminals 33P and 33Q are arranged in multiple pin rows on the circuit board 96 to facilitate the transmission of large currents. Adjacent pin rows can be aligned with each other as shown in the figure, or they can be staggered (misaligned).

[0035] As shown in Figure 2, each detection terminal 32 may also include a pin portion 321 and a contact portion 322, and the contact portion 322 may include a spring arm. In some embodiments, the joint portion 36 of the insulating housing 31 has a limiting hole 44, and the end of the contact portion 322 of the detection terminal 32 is disposed in the limiting hole 44.

[0036] Please refer to Figure 3, which is a perspective view of the insulating housing 31 of the board-end connector 30 shown in Figure 2. As shown, the insulating housing 31 also has a plurality of detection terminal slots 45 and a plurality of power terminal slots 46. Each detection terminal 32 is disposed in one of the detection terminal slots 45, and each group of power terminals 33 is disposed in one of the power terminal slots 46. The insulating housing 31 also has at least one stop groove 47, which is disposed on the edge of the power terminal slot 46. The limiting structure 334 of the aforementioned power terminal 33 engages with the stop groove 47.

[0037] As shown in Figure 3, in some embodiments, the base 35 of the insulating housing 31 further includes at least one positioning post 48, which protrudes from the bottom of the insulating housing 31 to position the insulating housing 31 on the circuit board 96. In some embodiments, each of the two wings 37 has a fixing hole 49 for receiving the aforementioned fixing member 38.

[0038] Please refer to Figure 4, which is a top view of the board-end connector 30 shown in Figure 1. As shown, the guide strip 40 of the insulating housing 31 serves as a foolproof structure to ensure that the wire-end connector 60 is connected to the board-end connector 30 in the correct orientation. In some embodiments, in the second direction K2, the widths W1 of the first guide strip 41 and W2 of the second guide strip 42 are different. In some embodiments, in the second direction K2, the distances G1 between the side of the first guide strip 41 and the side of the engagement portion 36 and G2 between the side of the second guide strip 42 and the side of the engagement portion 36 are different. In some embodiments, in the third direction K3, the distances H1 by which the first guide strip 41 protrudes beyond the engagement portion 36 and H2 by which the second guide strip 42 protrudes beyond the engagement portion 36 are different.

[0039] Please refer to Figures 5 and 6. Figure 5 is an exploded view showing some components of the wire connector 60 shown in Figure 1, and Figure 6 is a cross-sectional view showing the power connector assembly 29 shown in Figure 1. As shown, in this embodiment, the wire connector 60 includes a plate-shaped mating member with two wire terminals 63 located on opposite sides of the plate-shaped mating member and electrically isolated from each other. The plate-shaped mating member is configured to insert into the aforementioned slot 39 of the plate connector 30, contacting the detection terminal 32 and the power terminal 33 of the plate connector 30. The cable assembly 97 is electrically connected to the wire terminals 63 of the plate-shaped mating member.

[0040] As shown in Figures 5 and 6, the plate-shaped mating member may further include a terminal separator 64, which contains insulating material. The terminal separator 64 is disposed between two wire terminals 63 and isolates the two wire terminals 63. The two wire terminals 63 and the terminal separator 64 are stacked on a third-direction K3, with the two wire terminals 63 positioned on opposite sides of the terminal separator 64. The thickness of the stacked area of ​​the terminal separator 64 and the two wire terminals 63 is equal to or greater than 0.1 mm, preferably equal to or greater than 0.15 mm. The two wire terminals 63 are respectively configured to contact two rows of terminals of the plate-end connector 30, and the two wire terminals 63 can be clamped by the two rows of terminals of the plate-end connector 30. The two wire terminals 63 can transmit different voltages. The two wire terminals 63 are plate-shaped, and some areas can be bent as needed (see Figure 12).

[0041] As shown in Figures 5 and 6, each wire terminal 63 includes a contact portion 635 and a wiring portion 636, which are connected and arranged in the second direction K2. The contact portion 635 is configured to contact the detection terminal 32 and the power terminal 33 of the board connector 30. The contact portions 635 of the two wire terminals 63 are plate-shaped and located on opposite sides of the plate-shaped mating member. The contact portion 635 can be a rigid structure, and the detection terminal 32 and the power terminal 33 are kept in contact with the contact portion 635 by the elasticity of their spring arms. The wiring portion 636 connects to the cable assembly 97. In this embodiment, the wire terminal 63 is a flat plate structure extending straight along the second direction K2, and the cable assembly 97 extends out along the second direction K2.

[0042] As shown in Figures 5 and 6, in some embodiments, the thickness of the contact portion 635 of the wire terminal 63 in the third direction K3 is at least 0.4 mm to facilitate the transmission of large currents. In some embodiments, the thickness of the contact portion 635 of the wire terminal 63 is greater than or equal to 0.5 mm. In some embodiments, the lower edge of the plate-shaped mating member has at least one bevel, for example: the lower edge (or leading edge) of the contact portion 635 of the wire terminal 63 has at least one bevel 637, or the lower edge (or leading edge) of the terminal separator 64 has at least one bevel 647, to facilitate the insertion of the wire terminal 63 into the slot 39 of the plate connector 30.

[0043] As shown in Figures 5 and 6, in some embodiments, the terminal separator 64 includes a flat plate portion 641 and a flange 642. The flat plate portion 641 is disposed between two wire terminals 63, and the flange 642 is disposed on the outer edge of the flat plate portion 641, with the thickness of the flange 642 being greater than the thickness of the flat plate portion 641. When the terminal separator 64 is engaged with the wire terminals 63, the flange 642 of the terminal separator 64 covers the lower edge of the contact portion 635 of the wire terminals 63. In some embodiments, the flange 642 has a chamfered surface 647.

[0044] As shown in Figures 5 and 6, in some embodiments, the terminal separator 64 further includes at least one fixing post 643, which is disposed on at least one side surface of the flat plate portion 641. Correspondingly, the wire terminal 63 has at least one through hole 633, and the fixing post 643 extends through the through hole 633. In some embodiments, the fixing post 643 can be heat-fused to fix the wire terminal 63 to the terminal separator 64. In some embodiments, fixing posts 643 are provided on both sides of the terminal separator 64 to fix two wire terminals 63 respectively. In some embodiments, the wire terminal 63 also has a through hole 634, and the terminal separator 64 also has a through hole 644. The through holes 634 and 644 are aligned with each other, and the inner mold 62 of the wire connector 60 can be filled into the through holes 634 and 644 to facilitate the fixing of the wire terminal 63 and the terminal separator 64.

[0045] As shown in Figures 5 and 6, in some embodiments, the lower edge of the contact portion 635 of the wire terminal 63 has a first notch 631, the position of which corresponds to the detection terminal 32 of the board connector 30. In some embodiments, the terminal separator 64 has another notch corresponding to the first notch 631.

[0046] As shown in Figures 5 and 6, in some embodiments, the terminal separator 64 further includes a protrusion 645 disposed on the side of the terminal separator 64 away from the cable assembly 97 (or on the side away from the wiring portion 636 of the wire terminal 63). Correspondingly, the body 65 of the insulating housing 61 of the wire connector 60 has a positioning groove 84 that receives the protrusion 645 of the terminal separator 64 to position the wire terminal 63 and the terminal separator 64 within the insulating housing 61. In some embodiments, the body 65 of the insulating housing 61 further includes a positioning post 83, the edge of the wire terminal 63 away from the protrusion 645 abutting against the positioning post 83, such that the wire terminal 63 is positioned between the protrusion 645 and the positioning post 83.

[0047] As shown in Figures 5 and 6, in some embodiments, the body 65 of the insulating housing 61 of the wire-end connector 60 has a mating cavity 85 and a cable cavity 86. The mating cavity 85 is used to receive the board-end connector 30 (specifically, the mating portion 36 of the insulating housing 31 of the board-end connector 30 is configured to be inserted into the mating cavity 85), while the cable cavity 86 is used to accommodate a portion of the cable assembly 97. Two side openings 67 of the body 65 are located on both sides of the mating cavity 85 and communicate with it. The contact portion 635 of the wire-end terminal 63 is located in the mating cavity 85, with the lower edge of the contact portion 635 facing the entrance of the mating cavity 85, and the wiring portion 636 of the wire-end terminal 63 is located in the cable cavity 86. A partition wall 87 is provided between the mating cavity 85 and the cable cavity 86. Correspondingly, the wire end terminal 63 has a second notch 632 (the terminal separator 64 also has a corresponding notch). The second notch 632 receives the partition wall 87; in other words, the partition wall 87 is inserted into the second notch 632 to position the wire end terminal 63 and the terminal separator 64 of the plate-shaped mating member within the insulating housing 61. The portion of the plate-shaped mating member located in the mating cavity 85 has a thickness (excluding the beveled surface 647 at the leading edge) greater than or equal to 0.4 mm, preferably greater than or equal to 0.5 mm. The side of the cable cavity 86 away from the mating cavity 85 is the outlet, through which the cable assembly 97 exits. The positioning post 83 is located in the middle of the outlet and extends along the engagement direction K1 to divide the outlet into two areas. The cable assembly 97 connected to the wire end terminal 63 on one side of the plate-shaped mating member exits from one area, while the cable assembly 97 connected to the wire end terminal 63 on the other side of the plate-shaped mating member exits from the other area.

[0048] As shown in Figures 5 and 6, in some embodiments, the body 65 of the insulating housing 61 further has at least one first guide groove 81 and at least one second guide groove 82. The first guide groove 81 and the second guide groove 82 are disposed on the side of the mating cavity 85 and located on both sides of the side opening 67. The first guide groove 81 and the second guide groove 82 are respectively configured to receive the first guide strip 41 and the second guide strip 42 of the insulating housing 31 of the board-end connector 30, and the size and position of the first guide groove 81 and the second guide groove 82 respectively match the first guide strip 41 and the second guide strip 42. In some embodiments, the width of the first guide groove 81 and the width of the second guide groove 82 are different in the second direction K2. In some embodiments, the distance between the side of the first guide groove 81 and the side of the mating cavity 85 and the distance between the side of the second guide groove 82 and the side of the mating cavity 85 are different in the second direction K2. In some implementations, the depths of the first guide groove 81 and the second guide groove 82 on the third-party direction K3 are different.

[0049] As shown in Figures 5 and 6, in some embodiments, the body 65 of the insulating housing 61 further has at least one bevel 88, which is disposed on the side of the engagement cavity 85 away from its inlet. The bevel 88 can function to guide the wire terminals 63 and terminal separators 64 to the correct assembly position during the production of the wire connector 60.

[0050] As shown in Figures 5 and 6, in some embodiments, the body 65 of the insulating housing 61 of the wire-end connector 60 further has at least one hole 89, into which the inner mold 62 can be filled to facilitate fixing the inner mold 62 inside the insulating housing 61. In some embodiments, the manufacturing method of the wire-end connector 60 includes: (1) assembling the wire-end terminal 63 and the terminal separator 64 together (e.g., heat fusion fixing); (2) connecting the cable assembly 97 to the wire-end terminal 63 (e.g., welding the cable assembly 97 to the wire-end terminal 63); (3) installing the wire-end terminal 63, the terminal separator 64 and the cable assembly 97 together into the insulating housing 61; (4) after completing the above steps, forming the inner mold 62 inside the insulating housing 61 by injection molding, the inner mold 62 partially covering the wire-end terminal 63, the terminal separator 64 and the cable assembly 97, and exposing the contact portion 635 of the wire-end terminal 63. The inner mold 62 can fill the cable cavity 86 of the insulating shell 61 but not the joint cavity 85.

[0051] Please refer to Figure 7, which is a perspective view of some components of the power connector assembly 29 shown in Figure 1. As shown, the inner mold 62 may include a first portion 621 and a second portion 622. The first portion 621 covers the upper edge of the wire terminal 63 and the terminal separator 64 to facilitate fixing the wire terminal 63 and the terminal separator 64. The second portion 622 covers the end of the cable assembly 97 and the aforementioned wiring portion 636 of the wire terminal 63 to facilitate fixing the cable assembly 97 and the wire terminal 63. The aforementioned contact portion 635 of the wire terminal 63 is exposed outside the inner mold 62. At least one protrusion 623 may be formed on the side of the inner mold 62, corresponding to at least one hole 89 of the aforementioned insulating housing 61.

[0052] In some embodiments, at least one electronic component (not shown) is provided on the circuit board 96, and the electronic component is connected to the detection terminal 32 and the power terminal 33 of the board connector 30. The power supply process of the electronic component may include: (1) the electronic component receives a detection signal via the detection terminal 32, the detection signal indicating that the power terminal 33 and the wire connector 60 are stably connected; and (2) in response to receiving the detection signal, the electronic component allows the power supply to be supplied to the electronic component via the power terminal 33 to avoid damage or abnormal operation of the electronic component.

[0053] As shown in Figure 7, when the wire terminal 63 has the first notch 631, during the process of connecting the wire connector 60 to the board connector 30, the time when the detection terminal 32 contacts the wire terminal 63 is later than the time when the power terminal 33 contacts the wire terminal 63. In this way, it can be better ensured that the electronic components will receive the detection signal through the detection terminal 32 after the power terminal 33 and the wire terminal 63 are stably connected.

[0054] As shown in Figure 7, in some embodiments, in the engagement direction K1, the contact area 326 of the detection terminal 32 is positioned lower than the contact area 336 of the power terminals 33P and 33Q. In other words, the distance between the contact area 326 of the detection terminal 32 and the entrance of the slot 39 is greater than the distance between the contact area 336 of the power terminals 33P and 33Q and the entrance of the slot 39. This configuration also helps ensure that the electronic component receives the detection signal via the detection terminal 32 only after the power terminal 33 and the line terminal 63 are stably connected.

[0055] Please refer to Figure 8, which is a cross-sectional view illustrating a power connector assembly according to another embodiment of this disclosure. The differences between this embodiment and the previous embodiment are: (1) the wire terminals 63A of the wire connector 60A are disposed separately from each other, forming a slot 90A between them; (2) the contact portion 635A of the wire terminal 63A of the wire connector 60A includes a spring arm, the notch of which faces away from the slot 90A; (3) the contact portion 332A of the power terminal 33A of the board connector 30A is a rigid structure and extends straight, the contact portion 332A of the power terminal 33A is configured to insert into the slot 90A and contact the spring arm of the wire terminal 63A (in other words, the contact portion 332A of the power terminal 33A is held by the spring arms of the two wire terminals 63A). In addition, the detection terminal (not shown) of the board connector 30A can also be a rigid structure and extend straight, and can contact the spring arm of the wire terminal 63A; (4) A terminal separator 50A is provided between the contact portions 332A of the two sets of terminals of the board connector 30A. The structure of the terminal separator 50A can be similar to the aforementioned terminal separator 64. The terminal separator 50A can include a flat plate portion and a flange. The flat plate portion is clamped between the two power terminals 33A. The flange is provided on the outer edge of the flat plate portion, and the thickness of the flange is greater than the thickness of the flat plate portion, and covers the upper edge (or front edge) of the power terminal 33A and the detection terminal. In addition, the flange can have at least one inclined surface.

[0056] Please refer to Figure 9, which is a cross-sectional view illustrating a wire-end connector 60B according to another embodiment of this disclosure. In this embodiment, the wire-end terminals 63B of the wire-end connector 60B are also separately disposed, forming a slot 90B between them. Unlike the embodiment shown in Figure 8, the wire-end terminals 63B in this embodiment are rigid structures and extend straight without spring arms. The wire-end connector 60B further includes two contact elements 91B made of conductive material, disposed on the side of the wire-end terminal 63B facing the slot 90B, and electrically connected to the wire-end terminal 63B. Each of the two contact elements 91B includes a base 92B and at least one spring arm 93B. The base 92B can be fixed to the wire-end terminal 63B by riveting, snap-fitting, laser welding, or other suitable methods. The spring arm 93B connects to the base 92B and extends obliquely to the base 92B. The spring arm 93B is used to contact the power terminal 33A and the detection terminal of the aforementioned board-end connector 30A.

[0057] As shown in Figure 9, in some embodiments, each contact element 91B may include at least one first spring arm 931B and at least one second spring arm 932B, the first spring arm 931B extending toward the entrance of the slot 90B, and the second spring arm 932B extending away from the entrance of the slot 90B. In some embodiments, the first spring arms 931B and the second spring arms 932B are arranged alternately.

[0058] Please refer to Figures 10 and 11. Figure 10 is a perspective view of a power connector assembly according to another embodiment of this disclosure, and Figure 11 is a perspective view of the wire connector 60C shown in Figure 10. The wire connector 60C of this embodiment is a side-exit connector configured to connect with the board connector 30. One side of the insulating housing 61C of the wire connector 60C retains the aforementioned latch 66, side opening 67, and baffle 68 design, while the other side is changed to a closed wall and has a third guide groove 94C, which can be located between the first guide groove 81 and the second guide groove 82. The latch 66 is configured to engage with one of the latches 43 of the insulating housing 31 of the board connector 30 (see Figures 2 to 4), and the third guide groove 94C is used to receive the other latch 43. In addition, the wire connector 60C includes a pull strap 691C, which connects to the operating part 661 of the latch 66.

[0059] Please refer to Figures 12 and 13. Figures 12 and 13 are perspective views illustrating some components of the wire connector 60C shown in Figure 11. As shown, the wire connector 60C includes four wire terminals 63C: a first wire terminal AA, a second wire terminal AB, a third wire terminal AC, and a fourth wire terminal AD. All four wire terminals 63C are plate-shaped. The first wire terminal AA and the second wire terminal AB are located on one side of the terminal separator 64C, and the third wire terminal AC and the fourth wire terminal AD are located on the other side of the terminal separator 64C. The first wire terminal AA is generally aligned with the third wire terminal AC, while the second wire terminal AB is generally aligned with the fourth wire terminal AD. Each wire terminal 63C includes a contact portion 635C, a wiring portion 636C, and an intermediate portion 638C. The contact portion 635C extends along the engagement direction K1, and the wiring portion 636C is bent relative to the contact portion 635C. For example, the wiring portion 636C may extend along a third direction K3. The middle portion 638C connects the upper edge of the contact portion 635C and the wiring portion 636C, and is bent to form a rounded corner. The wiring portion 636C and the middle portion 638C can be covered by the inner mold 62C of the wire terminal connector 60C (see Figure 10), while the contact portion 635C is exposed outside the inner mold 62C. In some embodiments, the wiring portion 636C is wider than the contact portion 635C in the second direction K2. For wire terminals on the same side, such as the first wire terminal AA and the second wire terminal AB, one of the wire terminal terminals has a wider contact portion 635C that can contact a power terminal group and a detection terminal of the board-end connector 30, while the other wire terminal terminal has a narrower contact portion 635C that can only contact a power terminal group of the board-end connector 30.

[0060] As shown in Figures 12 and 13, the terminal separator 64C may include a flat plate portion 641C and two partition walls 648C disposed at the center of the flat plate portion 641C. The flat plate portion 641C is disposed between the first wire terminal AA and the third wire terminal AC, and between the second wire terminal AB and the fourth wire terminal AD. The two partition walls 648C protrude from the flat plate portion 641C, one partition wall 648C being disposed between the first wire terminal AA and the second wire terminal AB, and the other partition wall 648C being disposed between the third wire terminal AC and the fourth wire terminal AD. The flat plate portion 641C and the partition walls 648C can separate the four wire terminals 63C.

[0061] In some embodiments, the four terminals 63C are not in contact with each other and can transmit up to four different voltages. In some embodiments, the wiring portion 636C of the first terminal AA is in contact with the wiring portion 636C of the third terminal AC, and the first terminal AA can transmit the same voltage as the third terminal AC. In some embodiments, the wiring portion 636C of the second terminal AB is in contact with the wiring portion 636C of the fourth terminal AD, and the second terminal AB can transmit the same voltage as the fourth terminal AD.

[0062] As shown in Figures 12 and 13, the terminal separator 64C may further include one or more retaining portions 649C, which may be disposed on both sides and / or at the center of the plate portion 641C. Each retaining portion 649C has one or more recesses 646C. Correspondingly, each wire terminal 63C may further include at least one extension arm 70C, each extension arm 70C being inserted into one of the recesses 646C, thereby fixing the wire terminal 63C and the terminal separator 64C to each other. In addition, the terminal separator 64C may also include a flange 642C, which is disposed along the edge of the plate portion 641C and covers the lower edge of the contact portion 635C of the wire terminal 63C.

[0063] As shown in Figures 12 and 13, each terminal 63C has a contact portion 635C including a power contact portion 71C, which is configured to contact the power terminal 33 of the aforementioned board connector 30. The contact portions 635C of the first terminal AA and the fourth terminal AD also include signal contacts 72C, such that the contact portions 635C of the first terminal AA and the fourth terminal AD are wider than the contact portions 635C of the second terminal AB and the third terminal AC. The signal contacts 72C are configured to contact the detection terminal 32 of the aforementioned board connector 30. The terminal separator 64C may have a notch 73C, the position of which corresponds to the signal contact 72C.

[0064] Please refer to Figures 14 and 15. Figure 14 is a perspective view of a power connector assembly according to another embodiment of this disclosure, and Figure 15 is an exploded view of some components of the wire connector 60D shown in Figure 14. The wire connector 60D of this embodiment differs from the aforementioned wire connector 60C in that the wire terminal 63D has a flat plate structure, the wiring portion 636D of the wire terminal 63D extends substantially parallel to the contact portion 635D, and the wiring portion 636D and the contact portion 635D are arranged in the engagement direction K1. The cable assembly 97 connecting the wiring portion 636D of the wire terminal 63D also extends along the engagement direction K1 and extends out of the insulating housing 61D from the side of the insulating housing 61D away from the wire terminal 63D. In addition, the structure of the terminal separator 64D of the wire connector 60D can be similar to that of the aforementioned terminal separator 64C. For example, the terminal separator 64D can include a flat plate portion, a flange, a partition wall, a retaining portion, a notch, and other structures.

[0065] As shown in Figures 14 and 15, the board connector 30D paired with the wire connector 60D is a right angle type connector. The insulating housing 31D of the board connector 30D lies horizontally on the circuit board 96, and the mating direction K1 of the board connector 30D is approximately parallel to the surface of the circuit board 96.

[0066] Please refer to Figures 16 and 17. Figure 16 is an exploded view of the board-end connector 30D shown in Figure 14, and Figure 17 is a perspective view of some components of the board-end connector 30D shown in Figure 14. As shown, the contact portion 332D of the power terminal 33D of the board-end connector 30D is exposed in the slot 39 of the insulating housing 31D and points in the engagement direction K1. The lead portion 331D of the power terminal 33D is bent relative to the contact portion 332D. For example, the lead portion 331D may extend perpendicular to the circuit board 96 (see also Figure 14), in other words, the lead portion 331D may extend perpendicular to the engagement direction K1. The middle portion 333D of the power terminal 33D connects the lead portion 331D and the contact portion 332D and is bent to form a rounded corner. The detection terminal 32D of the board-end connector 30D may also include a lead portion 321D, a contact portion 322D, and a middle portion 323D forming an L-shaped structure. In addition, the insulating housing 31D of the board-end connector 30D may have some or all of the structural features of the aforementioned insulating housing 31. For example, the insulating housing 31D may include a slot 39, a guide bar 40, a hook 43, a detection terminal slot 45, a power terminal slot 46, and other structures.

[0067] Please refer to Figures 18 and 19. Figure 18 is a perspective view illustrating a power connector assembly according to another embodiment of this disclosure, and Figure 19 is a perspective view illustrating some components of the wire-end connector 60E shown in Figure 18. The difference between the wire-end connector 60E of this embodiment and the aforementioned wire-end connector 60 is that the wiring portion 636E of the wire-end terminal 63E is bent relative to the contact portion 635E. For example, the contact portion 635E may extend along the second direction K2, while the wiring portion 636E may extend along the third direction K3, forming an L-shaped wire-end terminal 63E. The wire-end terminal 63E also includes a middle portion 638E, which connects the side edge of the contact portion 635E and the side edge of the wiring portion 636E, and is bent to form a rounded corner. The body 65E of the insulating housing 61E and the inner mold 62E are bent corresponding to the wire-end terminal 63E. The cable assembly 97 extends along the third direction K3.

[0068] Please refer to Figure 20, which is an exploded view illustrating a wire-end connector 60F according to another embodiment of this disclosure. Compared to the aforementioned embodiment, the plate-shaped mating member of the wire-end connector 60F in this embodiment further includes a plurality of first signal terminals 74, which are electrically connected to the cable assembly 97 and used to transmit electronic signals. In this embodiment, the first signal terminals 74 are located on the side away from the cable assembly 97, relative to the wire-end terminals 63. The terminal separator 64F of the plate-shaped mating member has an extension area located on the side of the terminal separator 64F away from the cable assembly 97. The first signal terminals 74 are disposed in the extension area of ​​the terminal separator 64F and arranged along the second direction K2. The first signal terminals 74 can be disposed on both opposite sides of the plate-shaped mating member. In some embodiments, the first signal terminals 74 can be located on the side adjacent to the cable assembly 97 or between multiple sets of wire-end terminals. The contact area of ​​the first signal terminal 74 is exposed on the surface of the terminal separator 64F, while the foremost end can be fixed within the terminal separator 64F. Two latches 66F are located outside the wire terminal 63. Because the insertion and extraction forces required by the first signal terminal 74 and the wire terminal 63 are different, the two latches 66F are misaligned with the central axis of the engagement cavity 85 in the second direction K2 to compensate for the difference in insertion and extraction forces between the first signal terminal 74 and the wire terminal 63. In other words, the two latches 66F are eccentrically positioned so that when the wire connector 60F separates from the corresponding board connector (e.g., board connector 30F shown in Figure 21), the insertion and extraction forces relative to the torque generated by the latches 66F in the second direction K2 can be nearly balanced.

[0069] Please refer to Figure 21, which is an exploded view of a board-end connector 30F according to another embodiment of this disclosure. The board-end connector 30F is used to mate with the wire-end connector 60F shown in Figure 20. As shown, the board-end connector 30F includes a plurality of second signal terminals 54, which are configured to contact the first signal terminals 74 of the wire-end connector 60F. The second signal terminals 54 are provided upright on the circuit board 96 and arranged on one side of the detection terminal 32 and the power terminal 33. The second signal terminals 54 can be arranged in two rows in the second direction K2, with the two rows of second signal terminals 54 respectively provided on both sides of the slot 39 of the insulating housing 31F. The structure of the second signal terminals 54 can be similar to that of the detection terminal 32, for example, including the above-mentioned pin portion, contact portion, etc., and the position of the contact area of ​​the second signal terminal 54 is also lower than the contact area of ​​the power terminal 33. The insulating housing 31F may have signal terminal slots 55 for accommodating the second signal terminals 54, with each second signal terminal 54 housed within a signal terminal slot 55. The structure of the signal terminal slots 55 may be similar to that of the aforementioned detection terminal slot 45. The first signal terminal 74 and the second signal terminal 54 may be used to transmit low-frequency signals. In some embodiments, at least one of the second signal terminals 54 may serve as a detection terminal for generating a detection signal, in which case the detection terminal 32 may be omitted.

[0070] Please refer to Figure 22, which is an exploded view illustrating a power connector assembly according to another embodiment of this disclosure. The power connector assembly of this embodiment includes a board-end connector 30G and a wire-end connector 60G. Unlike the aforementioned embodiments, the wire-end connector 60G of this embodiment includes two latches 66G, which are disposed on opposite short sides of an insulating housing 61G and arranged in a second direction K2. Correspondingly, the insulating housing 31G of the board-end connector 30G includes two hooks 43G, which are disposed on opposite short sides of the insulating housing 31G and arranged in a second direction K2. Each latch 66G is configured to engage with a corresponding hook 43. A connector 692 of the unlocking device 69 extends across the insulating housing 61G in the second direction K2, and both ends of the connector 692 are respectively connected to the two latches 66G.

[0071] Please refer to Figure 23, which is a cross-sectional view showing some components of the wire connector 60G shown in Figure 22. The wire connector 60G of this embodiment is a right-angle connector, with the wiring portion 636G of the wire terminal 63G extending substantially perpendicular to the contact portion 635G. The wire terminal 63G may also include an intermediate portion 638G, which connects the upper edge of the contact portion 635C and the wiring portion 636C. In some embodiments, the intermediate portion 638G may include a double-folded structure. In some embodiments, the intermediate portion 638G may include a beveled structure.

[0072] Please refer to Figure 24, which is an exploded view illustrating a power connector assembly according to another embodiment of this disclosure. The power connector assembly of this embodiment includes a board-end connector 30H and a wire-end connector 60H. Unlike the aforementioned embodiments, the board-end connector 30H has two groups of power terminals 33 (i.e., power terminals 33 located on either side of the slot 39 of the insulating housing 31H) each containing four groups of power terminals 33 to transmit a larger current. A detection terminal 32 is disposed in the middle of each group of power terminals 33, dividing each group of power terminals 33 into two groups of power terminals 33 on each side of the detection terminal 32. Additionally, the unlocking device 69H includes a pull strap 691H. The pull strap 691H includes an interconnected operating section 693 and a connecting section 694. The connecting section 694 is closed and slidably passes through the operating portions 661H of the two latches 66H. In some embodiments, the operating portions 661H have through holes, and the connecting section 694 passes through the through holes of the operating portions 661H of the two latches 66H. When the user pulls the operating section 693 away from the board connector 30H, the connecting section 694 will pull the operating parts 661H of the two latches 66H closer to each other, thus unlocking the device.

[0073] In summary, the power connector and power connector assembly disclosed herein, through the above-described structural configuration, can increase the upper limit of the current it can carry, and have the characteristics of stable power supply and small size.

[0074] Although this disclosure has been described above with reference to embodiments, it is not intended to limit this disclosure.
