Additionally, the term "or" used herein should, depending on the actual situation, possibly include any one or a combination of more of the associated listed items.

[0022] Embodiment

[0023] Refer to Figure 1 and Figure 2 as shown, Figure 1 Schematic diagram of the electrical connector assembly according to an embodiment of the present invention, Figure 2 Exploded schematic diagram of the electrical connector assembly according to an embodiment of the present invention. An embodiment of the present invention provides an electrical connector assembly D, which includes a board-end connector 1 and a wire-end connector 2. The wire-end connector 2 can be detachably docked with the board-end connector 1.

[0024] Refer to Figures 2 to 4 as shown Figure 3 which is a schematic diagram of the board - end connector according to an embodiment of the present invention, Figure 4 and which is a top - view schematic diagram of the board - end connector according to an embodiment of the present invention. The board - end connector 1 includes an insulating base 11 and two conductive posts 12. The insulating base 11 includes a first fastening member 111. The insulating base 11 can be positioned when it is fixed to a circuit board (not shown in the figure) by positioning pins 114 at its bottom. The two conductive posts 12 are disposed on the insulating base 11 and are electrically connected to the circuit board. The two conductive posts 12 are arranged in an oblique manner, and the two conductive posts 12 and the first fastening member 111 are arranged along a diagonal line L of the insulating base 11. In other words, the diagonal line L is an extension line connecting the two conductive posts 12, and the first fastening member 111 is located on this extension line. That is, the first fastening member 111 is located at a vertex (corner) of the insulating base 11.

[0025] As Figure 3 shown, the insulating base 11 is square and has four side edges, and one of the side edges extends to form a side wall 112. The side wall 112 is arranged along the edge of the insulating base 11. The side wall 112 includes a bent portion 113, and the first fastening member 111 is fixed to the bent portion 113. The upper end of the first fastening member 111 has an inclined surface 111S that slopes downward (towards the negative Z - axis direction). The insulating base 11 forms a chamfered surface C2 between adjacent side edges, so when the side wall 112 is arranged along the edge of the insulating base 11, the bent portion 113 is formed following the design of the chamfered surface C2.

[0026] In addition, it should be noted that the present invention is not limited to the extension range of the side wall 112. As Figure 3 and Figure 4 shown, the side wall 112 extends along the side - edge of the insulating base 11 in the Y - axis direction and the edge of the chamfered edge, but the present invention is not limited thereto. The side wall 112 can further extend along the side - edge of the insulating base 11 in the X - axis direction. First, refer to Figure 10 as shown, the side wall 112 is exactly on the opposite side of the line - end connector 2 connecting the external cable B11, and it can further enhance the stability of the overall structure.

[0027] Furthermore, as Figure 4 shown, the insulating base 11 can define a first median line L1 and a second median line L2. The first median line L1 is located at the middle position between two opposite side edges among the four side edges, and the second median line L2 is at the middle position between the other two opposite side edges among the four side edges. The first median line L1 and the second median line L2 divide the insulating base 11 into four regions, and the first fastening member 111 is located in one of the four regions.

[0028] Refer to Figure 3 and Figure 5 as shown Figure 5Schematic diagram of the conductive post according to an embodiment of the present invention. The conductive post 12 includes a main body portion 121, a fixing portion 122, and a pin portion 123. The fixing portion 122 is connected between the main body portion 121 and the pin portion 123. The diameter H2 of the fixing portion 122 is greater than the diameter H1 of either the main body portion 121 or the pin portion 123. The conductive post 12 is fixed inside the insulating base 11 through the fixing portion 122, and the pin portion 123 exposes the bottom of the insulating base 11 and is electrically connected to a circuit board (not shown in the figure), and the main body portion 121 exposes the upper surface 11S of the insulating base 11. In addition, the insulating base 11 further includes a limiting post 13 disposed on the upper surface 11S. The limiting post 13 is adjacent to another vertex (corner) of the insulating base 11, adjacent to the vertex where the first fastening member 111 is located.

[0029] Referring to Figure 2 , Figure 6 and Figure 7 as shown in Figure 6 is a schematic diagram of the wire-end connector according to an embodiment of the present invention, Figure 7 is a top view schematic diagram of the wire-end connector according to an embodiment of the present invention. The wire-end connector 2 includes an insulating housing 21, a second fastening member 22, an upper cover 23, and two conductive members 24. The insulating housing 21 has a partition wall 214 inside, and the partition wall 214 is used to divide the internal space of the insulating housing 21 into two accommodation grooves 210. The side of the insulating housing 21 has two side openings 2101, the bottom of the insulating housing 21 has a plurality of through holes 2102, and the top of the insulating housing 21 has a top opening 2103. The two side openings 2101, the plurality of through holes 2102, and the top opening 2103 communicate the two accommodation grooves 210.

[0030] The upper cover 23 is disposed on the top of the insulating housing 21. The upper cover 23 has a plurality of fastening portions 231, and the side wall of the insulating housing 21 has a plurality of fastening holes V. The upper cover 23 is snapped onto the top opening 2103 of the insulating housing 21 through the plurality of fastening portions 231 engaging with the plurality of fastening holes V.

[0031] The insulating housing 21 has a first side wall 211, a second side wall 212, and a third side wall 213. The first side wall 211 is perpendicularly connected to the second side wall 212, the third side wall 213 is perpendicularly connected to the second side wall 212, the third side wall 213 is parallel to the first side wall 211, and the second side wall 212 is connected between the first side wall 211 and the third side wall 213. There is a corner area C between the first side wall 211 and the second side wall 212. The second fastener 22 is disposed in the corner area C. Specifically, the corner area C includes a chamfered surface C1, the included angle between the chamfered surface C1 and the first side wall 211 and the second side wall 212 is between 90 degrees and 180 degrees, and the second fastener 22 is disposed on the chamfered surface C1. The two side openings 2101 are adjacent to the first side wall 211 and the third side wall 213 respectively. In the X-axis direction, the width of the first side wall 211 is smaller than the width of the third side wall 213. Therefore, there is a step difference between the two side openings 2101 and they are not in the same plane.

[0032] As Figure 7 shown, similar to the insulating base 11, the insulating housing 21 can also define a first center line L1 and a second center line L2. The second center line L2 is parallel to the first side wall 211 and the third side wall 213 and is located at the middle position between the first side wall 211 and the third side wall 213. The first center line L1 is perpendicular to the first side wall 211 and the third side wall 213 and intersects at the middle position of the third side wall 213. The chamfered surface C1 intersects with the first side wall 211 at a first boundary line R1, and the chamfered surface C1 intersects with the second side wall 212 at a second boundary line R2. The position of the first boundary line R1 does not exceed the first center line L1 in the X-axis direction, and the position of the second boundary line R2 does not exceed the second center line L2 in the Y-axis direction. That is to say, the range of the corner area C can be defined as being between the first center line L1 and the second center line L2 and within one of the four divided areas.

[0033] In the prior art, the fasteners of the connector are all configured on the vertical side or the horizontal side of the housing, that is, the housing is not specially designed with a chamfered surface for setting the fastener. Generally, the user holds the connector with the thumb and the middle finger and presses the fastener with the index finger. However, the included angles between the thumb, index finger, and middle finger are different. Therefore, when the user picks up the housing, it is usually not easy for the index finger to exert force. In comparison, as shown in FIGS. 1 and Figure 7As shown, in the present invention, the second card fixing member 22 is arranged on the chamfered surface C1 of the insulating housing 21, and the first card fixing member 111 is arranged on the chamfered surface C2 of the insulating base 11. When the user holds the wire-end connector 2 with a hand (such as the right hand) to plug it into the board-end connector 1, the thumb touches the third side wall 213 of the insulating housing 21, the middle finger touches the first side wall 211, and the index finger can be properly placed on the second card fixing member 22 on the chamfered surface C1. In other words, the position of the second card fixing member 22 is designed in cooperation with the human gesture, and the user will not feel uncomfortable when applying force. In other words, by arranging the second card fixing member 22 on the chamfered surface C1 located between the first side wall 211 and the second side wall 212, the present invention enables the user to operate more smoothly.

[0034] However, the above examples are only one feasible embodiment and are not intended to limit the present invention. In another feasible embodiment, the corner area C may include a right-angle surface (i.e., the insulating housing 21 has no chamfer design), and the second card fixing member 22 is arranged on the right-angle surface (for example: the second side wall 212, and is offset to the right vertex and not on the second median line L2); similarly, the chamfered surface C2 of the insulating base 11 also needs to be correspondingly changed to a right-angle surface. In other words, the structure of the insulating housing 21 in the corner area C can be designed as a right-angle surface or a chamfered surface C1. Compared with the right-angle surface design, the chamfered surface C1 design can further reduce the size of the insulating housing 21 and save more manufacturing material costs. In addition, the present invention is not limited by the position of the chamfered surface C1. In other embodiments of the present invention, the chamfered surface C1 can also be arranged between the second side wall 212 and the third side wall 213 to be applicable to users with the left hand as the dominant hand.

[0035] As Figure 2 and Figure 7 shown, the interior of the insulating housing 21 further includes a guiding channel 216, and the guiding channel 216 penetrates the bottom of the insulating housing 21. The second card fixing member 22 includes a hook portion 221 and a pressing portion 222. Each conductive member 24 includes a hollow cylindrical structure 241 and a plate-like structure 242. The axial direction (Z-axis direction) of the hollow cylindrical structure 241 is perpendicular to the extending direction (X-axis direction) of the plate-like structure 242.

[0036] Refer to Figures 8 to 10 shown, Figure 8 is a schematic diagram of the wire-end connector of the embodiment of the present invention docking with the board-end connector, Figure 9 is a schematic diagram of the electrical connector assembly of the embodiment of the present invention externally connecting to the bus connector, Figure 10Partial schematic diagram of the external bus connector of the electrical connector assembly according to an embodiment of the present invention. When assembling the wire-end connector 2, the hollow cylindrical structure 241 is located in the accommodating groove 210, and the plate-like structure 242 extends along the extending direction (X-axis direction) and towards the side opening 2101 to the outside of the insulating housing 21. From Figure 10 the top-down perspective view, the two conductive members 24 are arranged obliquely, so the two plate-like structures 242 are not flush in the extending direction. The two plate-like structures 242 are respectively adjacent to and parallel to the first side wall 211 and the third side wall 213.

[0037] As Figure 2 and Figure 8 shown, when the wire-end connector 2 is docked with the board-end connector 1, the insulating housing 21 is engaged with the insulating base 11 along a docking direction (Z-axis direction). The chamfered surface C1 of the insulating housing 21 overlaps the chamfered surface C2 of the insulating base 11, so that the second fastening member 22 is clamped to the first fastening member 111. Further, the hook portion 221 of the second fastening member 22 abuts against the inclined surface 111S of the first fastening member 111 and moves along the inclined surface 111S to the lower part of the first fastening member 111, and abuts against the bottom of the first fastening member 111, so that the insulating housing 21 is fixed to the insulating base 11. In addition, when the insulating housing 21 is engaged with the insulating base 11, the two conductive posts 12 respectively pass through two of the through holes 2102 and are respectively electrically connected to the two conductive members 24, and the limiting post 13 is inserted into the guiding channel 216 for positioning between the insulating housing 21 and the insulating base 11. Further, the limiting post 13 is a hollow rectangular column, and a nut (not shown in the figure) can be installed in the limiting post 13, and then a screw post (not shown in the figure) is inserted for locking to be fixed on the circuit board.

[0038] As Figure 9 and Figure 10 shown, the two conductive members 24 can be connected to an external connector, for example but not limited to, a bus bar clip connector B1 that can be used to transmit large current. Each of the two sets of cables B11 of the bus connector B1 has a connecting portion B12, and the connecting portion B12 of the bus connector B1 is connected to the joint surface 242S of the corresponding plate-like structure 242 by ultrasonic welding. The joint surface 242S is located on the inner side surface of the plate-like structure 242, so the two connecting portions B12 are located between the two plate-like structures 242.

[0039] As Figure 7 and Figure 10As shown, each conductive member 24 is provided with a rib portion 243 on the outer side wall of its hollow cylindrical structure 241, and two grooves 215 are respectively provided on both sides of the partition wall 214 in the insulating housing 21 corresponding to the positions of the two accommodating grooves 210. When the two hollow cylindrical structures 241 are respectively arranged in the insulating housing 21, the two rib portions 243 are respectively clamped in the two grooves 215. Since the two conductive members 24 are arranged in an oblique arrangement, the projected areas of them projected onto the same plane (any plane parallel to the YZ plane, for example, the outer surface of the second side wall 212) along the extending direction (X-axis direction) will overlap each other. In other words, part of the areas of the two conductive members 24 fall on the second center line L2. Thereby, the wire-end connector 2 can further achieve the effect of reducing the volume. And the conductive posts 12 of the board-end connector are staggered from each other in the projected area projected onto the YZ plane and do not overlap each other.

[0040] Refer to again Figure 2 As shown, the wire-end connector 2 may further include two auxiliary conductive members 25, which are respectively arranged in the two hollow cylindrical structures 241. The auxiliary conductive members 25 are in an annular structure. When each conductive post 12 is inserted into the corresponding hollow cylindrical structure 241, the auxiliary conductive member 25 is sleeved on the conductive post 12, so that the conductive post 12 is electrically connected to the conductive member 24 through the corresponding auxiliary conductive member 25. For example, the auxiliary conductive member 25 may be a crown spring terminal, which may include a plurality of conductive elastic arms. Each conductive elastic arm is a cantilever structure, that is, one end is a fixed end and the other end is a free end. When the conductive post 12 is inserted into the hollow cylindrical structure 241 equipped with the auxiliary conductive member 25, the conductive post 12 will physically contact each conductive elastic arm, and each conductive elastic arm will be elastically deformed under extrusion.

[0041] On the other hand, as Figure 9 and Figure 10 shown, when the wire-end connector 2 is to be detached from the board-end connector 1, the user (right hand) holds the wire-end connector 2, and the index finger presses the pressing portion 222, applying a force towards the insulating housing 21 to the pressing portion 222, and driving the hook portion 221 to no longer abut against the bottom of the first fastening member 111, so that the second fastening member 22 is detached from the first fastening member 111.

[0042] Beneficial effects of the embodiment

[0043] For the electrical connector assembly D provided by the present invention, through the technical solution of "the insulating housing 21 has a first side wall 211 and a second side wall 212 that are vertically adjacent, there is a corner area C between the first side wall 211 and the second side wall 212, and the insulating housing 21 is provided with a second fastening member 22 in the corner area C", the second fastening member 22 is arranged in the corner area C of the insulating housing. Thereby, the user can hold the insulating housing 21 with an ergonomic gesture, which is beneficial to operating the wire-end connector 2 to be plugged and unplugged from the board-end connector 1.

[0044] Furthermore, in existing connectors, the fastening members are all arranged on the vertical side or the horizontal side of the housing, that is, the housing is not specially designed with a chamfered surface for arranging the fastening members. Therefore, when the user picks up the housing, it is usually not easy to apply force with the fingers. In contrast, as shown in FIGS. 1 and Figure 7 As shown, in the present invention, the second fastening member 22 is arranged on the chamfered surface C1 of the insulating housing 21, and the first fastening member 111 is arranged on the chamfered surface C2 of the insulating base 11. When the user picks up the wire-end connector 2 with a hand (for example, the right hand) to plug it into the board-end connector 1, the thumb touches the third side wall 213 of the insulating housing 21, the middle finger touches the first side wall 211, and the index finger can be appropriately placed on the second fastening member 22 on the chamfered surface C1. In other words, the position of the second fastening member 22 is designed in accordance with the human gesture, and the user will not feel that it is not easy to apply force when using it. In other words, by arranging the second fastening member 22 on the chamfered surface C1 located between the first side wall 211 and the second side wall 212, the present invention enables the user to operate more smoothly.
