[0148] For a more detailed and complete description of the present invention, reference is made to the accompanying drawings and various embodiments described below. The components in the drawings are not drawn to scale and are provided solely for illustrative purposes. Numerous practical details are described below to provide a thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention may be practiced without one or more of these practical details, and therefore, these details should not be construed as limiting the present invention.

[0149] Please refer to Figure 1 , which illustrates an assembly diagram of a power connector assembly 29 according to one embodiment of the present invention. As shown, the power connector assembly 29 includes a board connector 30 and a cable connector 60. The board connector 30 is mounted on a circuit board 96, while the cable connector 60 is connected to one end of a cable assembly 97. The board connector 30 and the cable connector 60 can be interconnected to transmit power. In some embodiments, electronic components (not shown, such as chips) are mounted on the circuit board 96. The electronic components are connected to the board connector 30 via conductive traces on or within 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. In this embodiment, the board connector 30 is a vertical type connector. The board connector 30 is mounted upright on the circuit board 96, and its mating direction K1 (mating direction) is substantially perpendicular to the circuit board 96. The power connector assembly 29 of the present invention can be used in computer servers, but is not limited thereto.

[0150] Please refer to Figure 2 , which is a drawing Figure 1 An exploded view of the power connector assembly 29 is shown. As shown, the board connector 30 includes an insulating housing 31 and a plurality of terminals, including at least one detection terminal 32 and a plurality of power terminals 33. The insulating housing 31, the detection terminals 32, and the power terminals 33 are all fixedly mounted on the circuit board 96, with the detection terminals 32 and the power terminals 33 disposed within the insulating housing 31. The insulating housing 31 comprises an insulating material, while the detection terminals 32 and the power terminals 33 comprise a conductive material, such as copper.

[0151] like Figure 2 As shown, the line end connector 60 includes an insulating housing 61 and a plurality of line end terminals 63 disposed in the insulating housing 61 (see Figure 5), the wire end terminal 63 includes a conductive material (for example, copper), and is configured to contact and electrically connect the detection terminal 32 and the power terminal 33 of the board end connector 30. The cable assembly 97 includes a plurality of cables, one end of the cable is electrically connected to the wire end terminal 63 (for example, the cable can be fixed to the wire end terminal 63 by welding), and extends from one side of the insulating shell 61. The wire end connector 60 also includes an inner mold 62. The inner mold 62 is disposed in the insulating shell 61 and partially covers the wire end terminal 63 and the cable assembly 97. The inner mold 62 can position the wire end terminal 63 and the cable assembly 97 in the insulating shell 61 and ensure that the wire end terminal 63 and the cable assembly 97 are firmly connected (for example, protecting the welding points of the wire end terminal 63 and the cable assembly 97). The inner mold 62 includes an insulating material and the inner mold 62 can be formed by injection molding.

[0152] like Figure 2 As shown, the insulating housing 61 of the cable connector 60 includes a body 65 and two latches 66 disposed on either side of the body 65. The two latches 66 are disposed on either side of the body 65. In this embodiment, the two latches 66 are disposed 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 securely engage with the insulating housing 31 of the board connector 30 to ensure a secure connection between the board connector 30 and the cable connector 60. The insulating housing 61 has a recess corresponding to the latch 66. The recess's appearance matches the structure of the latch 66, thereby accommodating the latch 66 in part or in whole. Each latch 66 further includes an operating portion 661 and a latching portion 662, located on either side of the pivot structure 663. The outer surface of the latching portion 662 is flush with or lower than the outer surface of the insulating housing 61. The latch portion 662 is configured to be engaged and fixed with the insulating housing 31 of the board-end connector 30. The operating portion 661 can be pressed by the user. When the operating portion 661 is pressed, the latch portion 662 is separated from the insulating housing 31 of the board-end connector 30, allowing the line-end connector 60 to be separated from the board-end connector 30. The outer surface of the operating portion 661 is flush with or higher than the outer surface of the insulating housing 61. Therefore, providing a groove at the position of the insulating housing 61 corresponding to the tenon 66 can reduce the height of the tenon 66 protruding outward, thereby reducing the overall size of the line-end connector 60. Figure 2 As shown, in some embodiments, the body 65 of the insulating housing 61 of the line end connector 60 has two side openings 67 (also refer to Figure 6), two side openings 67 are provided on opposite sides of the line terminal 63, and two latches 66 are provided facing the two side openings 67, respectively. In some embodiments, the body 65 further includes two baffles 68, each of which partially shields the corresponding side opening 67 and latch 66, protecting the latch 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 line terminal connector 60 in the third direction K3) is equal to or greater than 10 mm, preferably equal to or greater than 15 mm.

[0153] like Figure 2 As shown, in some embodiments, the wire end connector 60 further includes an unlocking device 69, which is configured to connect the two tenons 66. The unlocking device 69 includes a drawstring 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 parts 661 of the two tenons 66. The drawstring 691 is connected to the connector 692 and is arranged in the middle of the connector 692. The drawstring 691 can be pulled by the user, and the user pulling the drawstring 691 can achieve the same effect as pressing the operating part 661 of the tenon 66, allowing the wire end connector 60 to be separated from the board end connector 30. In some embodiments, the connector 692 can have a curved shape. In some embodiments, the connector 692 can be an elastic plastic part.

[0154] like Figure 2 As shown, the insulating housing 31 of the board connector 30 includes a base 35 and a joint 36. The base 35 is located on the side of the board connector 30 that is closer to the circuit board 96. The joint 36 is located on the side of the board connector 30 that is farther from the circuit board 96. The joint 36 extends into the line connector 60 when the board connector 30 is connected to the line connector 60.

[0155] like Figure 2 As shown, in some embodiments, the base 35 of the insulating shell 31 includes two wings 37, and the two wings 37 are arranged on opposite sides of the base 35, and each is fixedly connected to the circuit board 96 through a fixing member 38. The two wings 37 are a protruding structure compared to the base 35; that is, the base 35 is located between the two wings 37. At the same time, in the second direction K2, the two wings 37 protrude outward compared to the joint 36. The fixing member 38 is, for example, a metal sheet, and the fixing member 38 can hook the wings 37. In some embodiments, the base 35 of the insulating shell 31 has an opening 34, which is arranged adjacent to the circuit board 96 and exposes the detection terminal 32 and a portion of the power terminal 33 (also refer to Figure 1 ) to facilitate heat dissipation of the detection terminal 32 and the power terminal 33.

[0156] like Figure 2As shown, the joint portion 36 of the insulating housing 31 has a slot 39. The slot 39 and the opening 34 are located on opposite sides of the insulating housing 31. The slot 39 is used to receive the terminal 63 of the line connector 60. The detection terminal 32 and the power terminal 33 are partially exposed in the slot 39, contacting the terminal 63 of the line connector 60. When the detection terminal 32 contacts the terminal 63, a detection signal is generated, indicating the connection status or power supply status between the board connector 30 and the line connector 60. Because the detection terminal 32 and at least one power terminal 33 contact the same terminal 63, the generated signal accurately reflects 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 the joint portion 36) and two side openings on the side surfaces of the insulating housing 31 (or the joint portion 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 surface and two side surfaces of the insulating housing 31 are chamfered at their junctions. In other embodiments, the board connector 30 can also be connected to an edge card, and the slot 39 can be used to receive the edge card, with the detection terminals 32 and the power terminals 33 configured to contact the electrical contacts of the edge card.

[0157] like Figure 2 As shown, in some embodiments, the joint portion 36 of the insulating housing 31 includes at least one hook 43, and the hook portion 662 of at least one of the two tenons 66 of the wire end connector 60 is configured to be engaged with the hook 43. In this embodiment, the joint portion 36 of the insulating housing 31 includes two hooks 43 (also refer to Figure 4 ), two hooks 43 are provided on opposite sides of the joint portion 36 and are respectively engaged with the two tenons 66 of the line end connector 60.

[0158] like Figure 2 As shown, in some embodiments, the joint portion 36 of the insulating housing 31 further includes at least one guide bar 40, which is disposed on a side surface of the joint portion 36 and extends in the joint direction K1 of the board-end connector 30 and the line-end connector 60. In some embodiments, the joint portion 36 of the insulating housing 31 includes at least one first guide bar 41 and at least one second guide bar 42, and the first guide bar 41 and the second guide bar 42 have different sizes, positions, or both sizes and positions.

[0159] like Figure 2As shown, the detection terminals 32 and power terminals 33 of the board connector 30 are arranged upright on the circuit board 96 and are divided into two groups. The two groups of terminals are respectively arranged on either side of the slot 39 of the insulating housing 31, forming two rows of terminals. Each group of terminals can include at least one set of power terminals, and each set of power terminals includes multiple power terminals; that is, the board connector 30 can include at least two sets of power terminals, which are arranged on either side of the slot 39 of the insulating housing 31. The contact portions 332 (elastic 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, with two power terminals 33 forming a group. The detection terminal 32 and the two sets of power terminals 33 are arranged in the second direction K2, which is substantially perpendicular to the engagement direction K1, with the detection terminal 32 positioned between the two sets of power terminals 33. The two sets of power terminals 33 can transmit the same or different voltages. In some embodiments, one of the two groups of terminals includes the detection terminal 32, while the other group does not include the detection terminal 32. That is, the detection terminal 32 is only provided on one side of the slot 39, and is provided to correspond to the line terminal 63 transmitting the positive voltage in the line terminal connector 60. Figure 2 As shown, each power terminal 33 includes a pin portion 331, a contact portion 332, and an intermediate portion 333 connected between 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 outside the insulating housing 31 to electrically connect to 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 multiple 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 elastic arm. The intermediate portion 333 may include a retaining structure 334, which allows the power terminal 33 to be locked and secured to the insulating housing 31. The retaining structure 334 may be, for example, a protrusion protruding from the side of the intermediate portion 333 and / or protrusions protruding from the left and right sides of the intermediate portion 333.

[0160] like Figure 2 As shown, in this embodiment, the number of the tail ends of the pin portion 331 is three, and the contact portion 332 includes a single cantilever. In other embodiments, the contact portion 332 may include multiple elastic arms, and the multiple elastic arms are arranged in the second direction K2.

[0161] like Figure 2As shown, in this embodiment, each set of power terminals 33 includes power terminals 33P and 33Q. The pin portions 331 and intermediate portions 333 of the power terminals 33P and 33Q are separated from each other in a third direction K3, which is substantially perpendicular to the engagement direction K1 and may also be perpendicular to the second direction K2. In other words, the arrangement direction of the contact portions 332 and the arrangement direction of the intermediate portions 333 of each set of power terminals 33 are perpendicular to each other. The power terminal 33P further includes a bent portion 335 connected between the contact portion 332 and the intermediate portion 333. The notch of the bent portion 335 is oriented away from the power terminal 33Q, so that the contact areas 336 of the contact portions 332 of the power terminals 33P and 33Q (located on the spring arm and used to contact the terminal terminals 63 of the terminal 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 to plug the line-end connector 60 into the board-end connector 30. In other words, the contact areas 336 of the two power terminals 33P and 33Q are located at different distances from the entrance of the slot 39. Furthermore, the multiple tail ends of the pin portions 331 of the power terminals 33P and 33Q of each set of power terminals 33 are arranged in multiple pin rows on the circuit board 96 to facilitate high current transmission. Adjacent pin rows can be aligned, as shown, or they can be offset (misaligned).

[0162] like Figure 2 As shown, each detection terminal 32 may also include a pin portion 321 and a contact portion 322, and the contact portion 322 may include an elastic 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.

Each of the aforementioned detection terminals 32 is disposed in one of the detection terminal slots 45, while each group of power terminals 33 is disposed in one of the power terminal slots 46. The insulating housing 31 further comprises at least one stop slot 47 disposed on the edge of the power terminal slot 46. The stop structure 334 of the aforementioned power terminal 33 engages with the stop slot 47.

In some embodiments, the two wings 37 each have a fixing hole 49 for accommodating the aforementioned fixing member 38.

[0165] Please refer to Figure 4 , which is a drawing Figure 1 A top view of the board-side connector 30 is shown. As shown, the guide bar 40 of the insulating housing 31 serves as a foolproof structure, ensuring that the wire-end connector 60 is connected to the board-side connector 30 in the correct orientation. In some embodiments, in the second direction K2, the width W1 of the first guide bar 41 and the width W2 of the second guide bar 42 differ. In some embodiments, in the second direction K2, the distance G1 between the side of the first guide bar 41 and the side of the joint 36 and the distance G2 between the side of the second guide bar 42 and the side of the joint 36 differ. In some embodiments, in the third direction K3, the distance H1 that the first guide bar 41 protrudes from the joint 36 and the distance H2 that the second guide bar 42 protrudes from the joint 36 differ.

[0166] Please refer to Figure 5 and Figure 6 . Figure 5 To illustrate Figure 1 The exploded view of the part of the terminal connector 60 is shown.

As shown, in this embodiment, the cable connector 60 includes a plate-shaped mating member, which includes two cable terminals 63. The two cable terminals are located on opposite sides of the plate-shaped mating member and are electrically isolated from each other. The plate-shaped mating member is configured to be inserted into the aforementioned slot 39 of the board-shaped connector 30 and contact the detection terminals 32 and power terminals 33 of the board-shaped connector 30. The cable assembly 97 is electrically connected to the cable terminals 63 of the plate-shaped mating member.

[0167] like Figure 5 and Figure 6 As shown, the plate-like docking member may further include a terminal separator 64, which includes an insulating material. The terminal separator 64 is arranged between the two wire-end terminals 63 and isolates the two wire-end terminals 63. The two wire-end terminals 63 and the terminal separator 64 are stacked in the third direction K3, and the two wire-end terminals 63 are arranged on opposite sides of the terminal separator 64. The thickness of the area where the terminal separator 64 and the two wire-end terminals 63 are stacked is equal to or greater than 0.1 mm, and preferably equal to or greater than 0.15 mm. The two wire-end terminals 63 are respectively configured to contact the two rows of terminals of the board-end connector 30, and the two wire-end terminals 63 can be clamped by the two rows of terminals of the board-end connector 30. The two wire-end terminals 63 can transmit different voltages. The two wire-end terminals 63 are plate-shaped, and some areas can be bent as needed (please refer to Figure 12 ).

[0168] like Figure 5 and Figure 6As shown, each wire end 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-end connector 30. The contact portions 635 of the two wire end terminals 63 are plate-shaped and are located on two opposite sides of the plate-shaped docking member. The contact portion 635 can be a rigid structure, and the detection terminal 32 and the power terminal 33 maintain contact with the contact portion 635 through the elastic force of their elastic arms. The wiring portion 636 is connected to the cable assembly 97. In this embodiment, the wire end terminal 63 is a flat plate structure extending straight along the second direction K2, and the cable assembly 97 is connected along the second direction K2.

[0169] like Figure 5 and Figure 6 As shown, in some embodiments, the contact portion 635 of the wire terminal 63 has a thickness of at least 0.4 mm in the third direction K3 to facilitate high current transmission. 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 inclined surface, for example, the lower edge (or front edge) of the contact portion 635 of the wire terminal 63 has at least one inclined surface 637, or the lower edge (or front edge) of the terminal separator 64 has at least one inclined surface 647, to facilitate insertion of the wire terminal 63 into the slot 39 of the board connector 30.

[0170] like Figure 5 and Figure 6 As shown, 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 the two end terminals 63, and the flange 642 is disposed at the outer edge of the flat plate portion 641. The flange 642 is thicker than the flat plate portion 641. When the terminal separator 64 is coupled to the end terminal 63, the flange 642 of the terminal separator 64 covers the lower edge of the contact portion 635 of the end terminal 63. In some embodiments, the flange 642 has a slope 647.

[0171] like Figure 5 and Figure 6As shown, in some embodiments, the terminal separator 64 further includes at least one fixing post 643, which is disposed on at least one side of the flat portion 641. Correspondingly, the wire end terminal 63 has at least one through-hole 633, through which the fixing post 643 extends. In some embodiments, the fixing post 643 can be heat-melted to secure the wire end terminal 63 to the terminal separator 64. In some embodiments, fixing posts 643 are disposed on both sides of the terminal separator 64, respectively for securing the two wire end terminals 63. In some embodiments, the wire end terminal 63 further has a through-hole 634, and the terminal separator 64 further has a through-hole 644. The through-holes 634 and 644 are aligned with each other, and the inner mold 62 of the wire end connector 60 can be inserted into the through-holes 634 and 644 to facilitate securing the wire end terminal 63 and the terminal separator 64.

[0172] like Figure 5 and Figure 6 As shown, in some embodiments, the lower edge of the contact portion 635 of the line terminal 63 has a first notch 631, and the position of the first notch 631 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.

[0173] like Figure 5 and Figure 6 As shown, in some embodiments, the terminal separator 64 further includes a protrusion 645, which is arranged on the side of the terminal separator 64 away from the cable assembly 97 (or the side away from the wiring portion 636 of the wire end terminal 63). Correspondingly, the body 65 of the insulating housing 61 of the wire end connector 60 has a positioning groove 84, which receives the protrusion 645 of the terminal separator 64 to position the wire end terminal 63 and the terminal separator 64 in the insulating housing 61. In some embodiments, the body 65 of the insulating housing 61 further includes a positioning column 83, and the edge of the wire end terminal 63 away from the protrusion 645 abuts against the positioning column 83, so that the wire end terminal 63 is positioned between the protrusion 645 and the positioning column 83. Figure 5 and Figure 6As shown, 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. The openings 67 on both sides of the body 65 are located on either side of the mating cavity 85 and communicate with the mating cavity 85. 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. The wiring portion 636 of the wire end terminal 63 is located in the cable cavity 86. A partition wall 87 is defined 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-like mating component within the insulating housing 61. The thickness of the portion of the plate-like mating component located within the mating cavity 85 (excluding the inclined surface 647 at the front edge) is greater than or equal to 0.4 mm, preferably greater than or equal to 0.5 mm. The side of the cable cavity 86 facing away from the mating cavity 85 is a cable outlet, through which the cable assembly 97 exits. The positioning post 83 is located in the middle of the wire outlet and extends along the joining direction K1 to divide the wire outlet into two areas. The cable assembly 97 connected to the wire end terminal 63 on one side of the plate-like docking piece is connected to one area, while the cable assembly 97 connected to the wire end terminal 63 on the other side of the plate-like docking piece is connected to the other area.

[0174] like Figure 5 and Figure 6 As shown, 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 sides of the engaging cavity 85 and on either side of the side opening 67. The first guide groove 81 and the second guide groove 82 are respectively configured to receive the first guide bar 41 and the second guide bar 42 of the insulating housing 31 of the board-end connector 30, and the sizes and positions of the first guide groove 81 and the second guide groove 82 respectively match those of the first guide bar 41 and the second guide bar 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 surface of the first guide groove 81 and the side surface of the engaging cavity 85 and the distance between the side surface of the second guide groove 82 and the side surface of the engaging cavity 85 are different in the second direction K2. In some embodiments, in the third direction K3 , the depth of the first guiding groove 81 and the depth of the second guiding groove 82 are different.

[0175] like Figure 5 and Figure 6As shown, in some embodiments, the body 65 of the insulating housing 61 further comprises at least one inclined surface 88, which is disposed on a side of the engaging cavity 85 away from the entrance thereof. The inclined surface 88 can guide the wire end terminal 63 and the terminal separator 64 to the correct assembly position during the production of the wire end connector 60.

[0176] like Figure 5 and Figure 6 As shown, in some embodiments, the body 65 of the insulating housing 61 of the wire end connector 60 further has at least one hole 89, and the inner mold 62 can be filled into the hole 89 to facilitate fixing the inner mold 62 in the insulating housing 61. In some embodiments, the manufacturing method of the wire end connector 60 includes: (1) combining the wire end terminal 63 and the terminal separator 64 together (for example, by hot-melt fixing); (2) connecting the cable assembly 97 to the wire end terminal 63 (for example, by 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 in 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 may fill the cable cavity 86 of the insulating housing 61 but not the coupling cavity 85 .

[0177] Please refer to Figure 7 , which is a drawing Figure 1 A partial perspective view of the power connector assembly 29 is shown. As shown, the inner mold 62 may include a first portion 621 and a second portion 622. The first portion 621 covers the upper edges of the terminal block 63 and the terminal separator 64 to facilitate securing the terminal block 63 and the terminal separator 64. The second portion 622 covers the end of the cable assembly 97 and the connection portion 636 of the terminal block 63 to facilitate securing the cable assembly 97 and the terminal block 63. The contact portion 635 of the terminal block 63 is exposed outside the inner mold 62. At least one protrusion 623 may be formed on the side surface of the inner mold 62, corresponding to the at least one hole 89 of the insulating housing 61.

[0178] In some embodiments, at least one electronic component (not shown) is disposed on the circuit board 96, and the electronic component is connected to the detection terminal 32 and the power terminal 33 of the board-side 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 line-side connector 60 are stably connected; and (2) the electronic component allows power to be supplied to the electronic component via the power terminal 33 in response to receiving the detection signal, thereby preventing damage or abnormal operation of the electronic component.

[0179] like Figure 7As shown, when the line terminal 63 has the first notch 631, during the process of connecting the line-end connector 60 to the board-end connector 30, the time point when the detection terminal 32 contacts the line-end terminal 63 is later than the time point when the power terminal 33 contacts the line-end terminal 63. In this way, it can be ensured that the electronic component will receive the detection signal through the detection terminal 32 only after the power terminal 33 and the line-end terminal 63 are stably connected.

[0180] like Figure 7 As shown, in some embodiments, in the bonding direction K1, the position of the contact area 326 of the detection terminal 32 is lower than the position of 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 above-mentioned slot 39 is greater than the distance between the contact area 336 of the power terminals 33P and 33Q and the entrance of the above-mentioned slot 39. This configuration also helps to ensure that the electronic component will receive the detection signal through the detection terminal 32 only after the power terminal 33 and the line terminal 63 are stably connected. Please refer to Figure 8 , which is a cross-sectional view of a power connector assembly according to another embodiment of the present invention. The differences between this embodiment and the aforementioned embodiment are: (1) the line terminal 63A of the line end connector 60A is arranged separately from each other, forming a slot 90A therebetween; (2) the contact portion 635A of the line terminal 63A of the line end connector 60A includes an elastic arm, the notch of the elastic arm is facing away from the slot 90A; (3) the contact portion 332A of the power terminal 33A of the board end connector 30A is a rigid structure and extends straightly. The contact portion 332A of the power terminal 33A is configured to be inserted into the slot 90A and contact the elastic arm of the line terminal 63A (in other words, the contact portion 332A of the power terminal 33A is clamped by the two elastic arms of the line end terminal 63A). In addition, the detection terminal (not shown) of the board-side connector 30A may also be a rigid structure and extend straightly, and may contact the elastic arm of the line-end terminal 63A; (4) a terminal separator 50A is provided between the contact portions 332A of the two sets of terminals of the board-side connector 30A. The structure of the terminal separator 50A may be similar to the aforementioned terminal separator 64. The terminal separator 50A may include a flat plate portion and a flange. The flat plate portion is clamped between the two power terminals 33A. The flange is provided at 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 may have at least one inclined surface.

[0181] Please refer to Figure 9 , which is a cross-sectional view of a line end connector 60B according to another embodiment of the present invention. The line end terminals 63B of the line end connector 60B of this embodiment are also separated from each other, and a slot 90B is formed between the two. Figure 8In the illustrated embodiment, the wire end terminal 63B of this embodiment is a rigid structure that extends straight and does not have a spring arm. The wire end connector 60B further includes two contact components 91B made of conductive material. The two contact components 91B are arranged on the side of the wire end terminal 63B facing the slot 90B and are electrically connected to the wire end terminal 63B. The two contact components 91B each include a base 92B and at least one spring arm 93B. The base 92B can be fixed to the wire end terminal 63B by riveting, snapping, laser welding, or other suitable means. The spring arm 93B is connected to the base 92B and extends obliquely to the base 92B. The spring arm 93B is used to contact the power terminal 33A and detection terminal of the board end connector 30A.

[0182] like Figure 9 As shown, in some embodiments, each contact element 91B may include at least one first elastic arm 931B and at least one second elastic arm 932B, wherein the first elastic arm 931B extends toward the entrance of the slot 90B, while the second elastic arm 932B extends away from the entrance of the slot 90B. In some embodiments, the first elastic arms 931B and the second elastic arms 932B are arranged in a staggered manner.

[0183] Please refer to Figure 10 and Figure 11 . Figure 10 A perspective view of a power connector assembly according to another embodiment of the present invention is shown. Figure 11 To illustrate Figure 10 The three-dimensional view of the line end connector 60C is shown. The line end connector 60C of this embodiment is a side-outlet connector, which is configured to connect to the board end connector 30. One side of the insulating shell 61C of the line end connector 60C retains the design of the aforementioned latch 66, side opening 67 and baffle 68, while the other side is changed to a closed wall and has a third guide groove 94C. The third guide groove 94C can be located between the first guide groove 81 and the second guide groove 82. The latch 66 is configured to snap onto one of the hooks 43 of the insulating shell 31 of the board end connector 30 (see Figures 2 to 4 ), the third guide groove 94C is used to receive another hook 43. In addition, the wire end connector 60C includes a pull belt 691C, which is connected to the operating portion 661 of the tenon 66.

[0184] Please refer to Figure 12 and Figure 13 . Figure 12 and Figure 13 To illustrate Figure 11A three-dimensional view of a portion of the components of a terminal connector 60C is shown. As shown, the terminal connector 60C includes four terminal terminals 63C: a first terminal AA, a second terminal AB, a third terminal AC, and a fourth terminal AD. Each of the four terminal terminals 63C is plate-shaped. The first and second terminal AA are positioned on one side of a terminal separator 64C, while the third and fourth terminal AC and AD are positioned on the other side of the terminal separator 64C. The first terminal AA is positioned approximately aligned with the third terminal AC, while the second terminal AB is positioned approximately aligned with the fourth terminal AD. Each terminal 63C includes a contact portion 635C, a wiring portion 636C, and an intermediate portion 638C. The contact portion 635C extends along a mating 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 is connected between the upper edge of the contact portion 635C and the connection portion 636C and is bent to form a rounded corner. The connection portion 636C and the middle portion 638C can be connected to the inner mold 62C of the wire end connector 60C (see Figure 10 ) is covered, while the contact portion 635C is exposed outside the inner mold 62C. In some embodiments, in the second direction K2, the connection portion 636C is wider than the contact portion 635C. For terminals on the same side, such as the first terminal AA and the second terminal AB, one of the terminal terminals has a wider contact portion 635C, capable of contacting one power terminal set and one detection terminal of the board connector 30, while the other has a narrower contact portion 635C, capable of contacting only one power terminal set of the board connector 30.

[0185] like Figure 12 and Figure 13 As shown, the terminal separator 64C may include a flat plate portion 641C and two partition walls 648C disposed in the center of the flat plate portion 641C. The flat plate portion 641C is disposed between the first and third terminal terminals AA and AC, and between the second and fourth terminal terminals AB and AD. The two partition walls 648C protrude from the flat plate portion 641C, with one partition wall 648C disposed between the first and second terminal terminals AA and AB, and the other partition wall 648C disposed between the third and fourth terminal terminals AC and AD. The flat plate portion 641C and the partition walls 648C separate the four terminal terminals 63C.

[0186] In some embodiments, the four terminal terminals 63C do not contact each other and can transmit up to four different voltages. In some embodiments, the connection portion 636C of the first terminal AA contacts the connection portion 636C of the third terminal AC, allowing the first terminal AA and the third terminal AC to transmit the same voltage. In some embodiments, the connection portion 636C of the second terminal AB contacts the connection portion 636C of the fourth terminal AD, allowing the second terminal AB and the fourth terminal AD to transmit the same voltage.

[0187] like Figure 12 and Figure 13 As shown, the terminal separator 64C may further include one or more retaining portions 649C, which may be disposed on either side of the flat portion 641C and / or in the center of the flat portion 641C. Each retaining portion 649C has one or more grooves 646C. Accordingly, each end terminal 63C may further include at least one extension arm 70C, each extension arm 70C being inserted into one of the grooves 646C, thereby securing the end terminal 63C and the terminal separator 64C to each other. Furthermore, the terminal separator 64C may further include a flange 642C disposed along the edge of the flat portion 641C and covering the lower edge of the contact portion 635C of the end terminal 63C.

[0188] like Figure 12 and Figure 13 As shown, the contact portion 635C of each terminal 63C includes a power contact portion 71C configured to contact the power terminal 33 of the board connector 30. The contact portions 635C of the first and fourth terminal AA and AD further include a signal contact portion 72C, such that the contact portions 635C of the first and fourth terminal AA and AD are wider than the contact portions 635C of the second and third terminal AB and AC. The signal contact portion 72C is configured to contact the detection terminal 32 of the board connector 30. The terminal separator 64C may have a notch 73C, the position of which corresponds to the signal contact portion 72C.

[0189] Please refer to Figure 14 and Figure 15 . Figure 14 A perspective view of a power connector assembly according to another embodiment of the present invention is shown. Figure 15 To illustrate Figure 14An exploded view of some components of the wire end connector 60D is shown. The difference between the wire end connector 60D of this embodiment and the aforementioned wire end connector 60C is that the wire end terminal 63D is a flat structure, the connection portion 636D of the wire end terminal 63D extends roughly parallel to the contact portion 635D, and the connection portion 636D and the contact portion 635D are arranged in the joining direction K1. The cable assembly 97 connecting the connection portion 636D of the wire end terminal 63D also extends along the joining direction K1 and passes through the insulating housing 61D from the side of the insulating housing 61D away from the wire end terminal 63D. In addition, the structure of the terminal separator 64D of the wire end connector 60D can be similar to the aforementioned terminal separator 64C. For example, the terminal separator 64D can include structures such as a flat plate portion, a flange, a partition wall, a retaining portion, and a notch.

[0190] like Figure 14 and Figure 15 As shown, the board-side connector 30D that matches the line-side connector 60D is a right-angle type connector. The insulating housing 31D of the board-side connector 30D lies horizontally on the circuit board 96, and the engagement direction K1 of the board-side connector 30D is substantially parallel to the surface of the circuit board 96. Figure 16 and Figure 17 . Figure 16 To illustrate Figure 14 The exploded view of the board connector 30D is shown, and Figure 17 To illustrate Figure 14 The board connector 30D is shown in a perspective view of a portion of the components. As shown in the figure, the contact portion 332D of the power terminal 33D of the board connector 30D is exposed in the slot 39 of the insulating housing 31D and points in the engagement direction K1. The pin portion 331D of the power terminal 33D is bent relative to the contact portion 332D. For example, the pin portion 331D may extend perpendicularly to the circuit board 96 (see also FIG. 1 ). Figure 14 ), in other words, the pin portion 331D may extend perpendicular to the joining direction K1. The middle portion 333D of the power terminal 33D is connected between the pin portion 331D and the contact portion 332D, and is bent to form a rounded corner. The detection terminal 32D of the board-side connector 30D may also include a pin portion 321D, a contact portion 322D, and a middle portion 323D forming an L-shaped structure. In addition, the insulating shell 31D of the board-side connector 30D may have some or all of the structural features of the aforementioned insulating shell 31.

[0191] Please refer to Figure 18 and Figure 19 . Figure 18 A perspective view of a power connector assembly according to another embodiment of the present invention is shown. Figure 19 To illustrate Figure 18 A three-dimensional view of some components of the wire end connector 60E is shown. 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 can extend along the second direction K2, while the wiring portion 636E can extend along the third direction K3, forming an L-shaped wire end terminal 63E. The wire end terminal 63E also includes an intermediate portion 638E, which is connected between 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 main body 65E and the inner mold 62E of the insulating shell 61E are bent corresponding to the wire end terminal 63E. The cable assembly 97 is connected along the third direction K3.

[0192] Please refer to Figure 20 , which is an exploded view of a wire end connector 60F according to another embodiment of the present invention. Compared to the aforementioned embodiment, the plate-shaped mating member of the wire end connector 60F of this embodiment further includes a plurality of first signal terminals 74. The first signal terminals 74 can be electrically connected to the cable assembly 97 and used to transmit electronic signals. In this embodiment, compared to the wire end terminals 63, the first signal terminals 74 are located on a side away from the cable assembly 97. The terminal separator 64F of the plate-shaped mating member has an extension region. The extension region is located on the side of the terminal separator 64F away from the cable assembly 97. The first signal terminals 74 are arranged in the extension region of the terminal separator 64F and arranged along the second direction K2. The first signal terminals 74 can be disposed on both opposing side surfaces of the plate-shaped mating member. In some embodiments, the first signal terminals 74 can be located on a 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, and the front end can be fixed inside the terminal separator 64F. The two latches 66F are located on the outside of the line terminal 63. Since the plug-in and pull-out forces required for the first signal terminal 74 and the line terminal 63 are different, the central axis of the two latches 66F in the second direction K2 is not aligned with the central axis of the coupling cavity 85 to compensate for the different plug-in and pull-out forces of the first signal terminal 74 and the line terminal 63. In other words, the two latches 66F are eccentrically arranged so that the line terminal connector 60F and the corresponding board terminal connector (for example Figure 21 When the board-end connector 30F shown is separated, in the second direction K2, the torque generated by the plug-in force relative to the tenon 66F can be nearly balanced.

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 disposed on either side 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 terminals 32, for example, including the aforementioned pin portions and contact portions, with the contact areas of the second signal terminals 54 also positioned lower than the contact areas of the power terminals 33. The insulating housing 31F can have signal terminal slots 55 for accommodating the second signal terminals 54, with each second signal terminal 54 being received within a signal terminal slot 55. The structure of the signal terminal slots 55 can be similar to that of the aforementioned detection terminal slots 45. The first signal terminal 74 and the second signal terminal 54 can be used to transmit low-frequency signals. In some embodiments, at least one of the second signal terminals 54 can be used as a detection terminal for generating a detection signal, and the detection terminal 32 can be omitted.

[0194] Please refer to Figure 22 , which is an exploded view of a power connector assembly according to another embodiment of the present invention.

[0195] Please refer to Figure 23 , which is a drawing Figure 22 A cross-sectional view of some components of a wire end connector 60G is shown. In this embodiment, the wire end connector 60G is a right-angle connector, with the connection portion 636G of the wire end terminal 63G extending approximately perpendicular to the contact portion 635G. The wire end terminal 63G may also include an intermediate portion 638G connected between the upper edge of the contact portion 635C and the connection portion 636C. In some embodiments, the intermediate portion 638G may include a folded structure. In some embodiments, the intermediate portion 638G may include a beveled structure.

[0196] Please refer to Figure 24 , which depicts an exploded view of a power connector assembly according to another embodiment of the present invention. This embodiment of the power connector assembly includes a board-side connector 30H and a line-side connector 60H. Unlike the previous embodiment, the two groups of power terminals 33 of the board-side connector 30H (i.e., the power terminals 33 located on either side of the slot 39 of the insulating housing 31H) each include four sets of power terminals 33, enabling higher current transmission. The detection terminals 32 are positioned in the middle of each group of power terminals 33, dividing each group of power terminals 33 into two groups of power terminals 33, one on each side of the detection terminal 32. Furthermore, 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 enclosed and slidably passes through the operating portions 661H of the two latches 66H. In some embodiments, the operating portion 661H has a through-hole, 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 pulls the operating portions 661H of the two latches 66H toward each other, unlocking the connector. In summary, the power connector and power connector assembly of the present invention, through the aforementioned structural configuration, can increase the upper limit of the current they can carry, while maintaining stable power supply and a compact size.
