Detailed implementation manner

[0025] The following detailed implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings.

[0026] This application discloses a power connector, which includes two rows of power terminals and a plurality of signal terminals. The plurality of signal terminals are located between the two rows of power terminals. In this way, the power terminals are located on both sides of the signal terminals, increasing the heat dissipation surface space of the power terminals and being beneficial to heat dissipation. The power terminals are relatively larger in size than the signal terminals, and the two rows of power terminals are located on both sides of the signal terminals, avoiding damage to the signal terminals during improper insertion. In some cases, with this symmetrical structure, the power connector can be inserted without distinguishing between the front and back directions.

[0027] Refer to Figure 1-10 As shown, it shows the first embodiment of this application. The power connector assembly includes a socket connector 100 and a plug connector 200. The power connector is applicable to the socket connector 100 and also applicable to the plug connector 200. The following will be a detailed description of this first embodiment.

[0028] Refer to Figure 1-4 As shown, the socket connector 100 in the first embodiment is a corner-type socket connector. After it is installed on a circuit board, the docking direction is parallel to the circuit board. The socket connector 100 includes an insulating body 10 and a plurality of first power terminals 21, a plurality of second power terminals 22, and a plurality of signal terminals 23 fixed to the insulating body 10. The plurality of first power terminals 21 are arranged in a first direction (the left-right direction shown in the drawing) to form a first power terminal row, the plurality of second power terminals 22 are arranged in the first direction to form a second power terminal row, the plurality of signal terminals 23 are arranged in the first direction, and the plurality of signal terminals 23 are located between the first power terminal row and the second power terminal row in a second direction (the up-down direction shown in the drawing). The first direction and the second direction are perpendicular to each other. The two rows of power terminals 21, 22 are located on both sides of the signal terminal 23, avoiding damage to the signal terminal 23 during improper insertion. At the same time, relative to the adjacent arrangement of the first and second power terminal rows, the first and second power rows of this application are respectively located on both sides of the signal terminal, and more space can be provided for the power terminals to dissipate heat. In some cases, with this symmetrical structure, especially when no chamfer is provided at the inner cut angle of the terminal hole, the plug connector can be inserted without distinguishing between the front and back directions.

[0029] In this embodiment, the insulating body 10 is provided with a plurality of first jacks 12, a plurality of second jacks 13 and a long slot 14. The plurality of first jacks 12 are arranged along a first direction to form a first jack row, the plurality of second jacks 13 are arranged along the first direction to form a second jack row, and the long slot 14 is located between the first jack row and the second jack row in a second direction. Each of the first jacks 12 is provided with the first power terminal 21, each of the second jacks 13 is provided with the second power terminal 22, and a plurality of the signal terminals 23 are arranged in the long slot 14. In this embodiment, when viewed from the docking direction (as Figure 3 shown), the plurality of first jacks 12 have different inscribed angles 123 to suit different application scenarios and avoid misinsertion of different systems; similarly, the plurality of second jacks 13 have different inscribed angles, and the first and second jacks are also asymmetric.

[0030] In this embodiment, in the second direction, the first power terminals 21, the signal terminals 23 and the second power terminals 22 are aligned with each other, as shown by the dashed line L1 in Figure 3 . Further, in this embodiment, the distance between adjacent first power terminals 21 is 3 mm, the distance between adjacent second power terminals 22 is 3 mm, and the distance between adjacent signal terminals 23 is 3 mm. In this way, the distance between the signal terminals 23 is the same as that between the power terminals, simplifying the design. In some other embodiments, the distance between adjacent first power terminals 21 along the first direction is the same as the distance between adjacent second power terminals 22 along the first direction, but the distance between adjacent signal terminals 23 along the first direction is less than or greater than the distance between adjacent first power terminals along the first direction. In some other embodiments, the distance between adjacent power terminals can be 2.5 mm, or 3.5 mm, or 5.7 mm to adapt to power transmission of different amperes.

[0031] In this embodiment, the signal terminals 23 are arranged in two rows along the second direction in the long slot 14. In some other embodiments, the signal terminals 23 are arranged in a single row along the second direction in the long slot 14.

[0032] In this embodiment, both the first power terminal 21 and the second power terminal 22 are pin terminals, and the signal terminal 23 is also a pin terminal. In the embodiment, the structures of the first and second power terminals are the same, and their sizes are larger than those of the signal terminal 23. The first power terminal 21 includes a contact portion 211 exposed in the first jack 12, a fixing portion 212 fixed to the insulating body, and a connecting portion 213 extending out of the insulating body. The first power terminal 21 has an L-shaped structure with the same front and rear dimensions and is used in a corner-type socket connector. The structure of the second power terminal 23 is the same as that of the first power terminal 21, except that its length is smaller. In this embodiment, the signal terminal 23 includes a contact portion 231, a fixing portion 232 fixed in the insulating body, and a connecting portion 233 extending out of the insulating body. The thickness of the signal terminal 23 in the second direction is smaller than that of the first / second power terminal, and the width of its contact portion 231 in the first direction is smaller than that of its fixing portion 232.

[0033] In this embodiment, referring Figure 3 As shown, a plurality of first jacks 12 have opposite first outermost inner edges 121 and second outermost inner edges 122 along the first direction, a plurality of second jacks 13 have opposite third outermost inner edges 131 and fourth outermost inner edges 141 along the first direction, the long groove 14 has opposite fourth outermost inner edges 141 and fifth outermost inner edges 142 along the first direction, and the first, third, and fifth outermost inner edges 121, 131, 141 are aligned with each other in the second direction, and the second, fourth, and sixth outermost inner edges 122, 132, 142 are aligned with each other in the second direction. Thus, the plug connector can have a neat outer surface during design, increasing the aesthetics of the connector.

[0034] The insulating body is provided with a fastening head 15 on an outer surface adjacent to the first power terminal 20, and the fastening head 15 is adjacent to the docking surface 110 of the insulating body 10.

[0035] Referring Figure 5-9 , the plug connector 200 includes an insulating body 50, a plurality of first power terminals 61, a plurality of second power terminals 62, and a plurality of signal terminals 63. The insulating body 50 includes a base portion 51 and a plurality of first insertion posts 52, a plurality of second insertion posts 53, and a longitudinal insertion post 54 protruding from the base portion 51. The first power terminals 61 are respectively arranged in the first insertion posts 52, the second power terminals 63 are respectively arranged in the second insertion posts 53, and a plurality of signal terminals 63 are arranged in the longitudinal insertion post 54.

[0036] In this embodiment, the first and second insertion posts 52 and 53 integrally extend from one surface of the base 51, and the longitudinal insertion post 54 is mounted and fixed on the base 51. In this way, it is convenient for the molding of the insulating body 50. The base 51 is provided with a fixing groove 511 penetrating through from front to back. The longitudinal insertion post 54 is assembled into the fixing groove 511 from back to front, and the mounting rib 542 provided at the rear end of the longitudinal insertion post 54 abuts against the base 51.

[0037] The base 51 is integrally provided with a clamping arm 55 near the first insertion post 52. Refer Figure 6 As shown, the front end 541 of the longitudinal insertion post 54 is located behind the front end 521 of the first insertion post 52. The front end 551 of the clamping arm 55 is located behind the front end 541 of the longitudinal insertion post 54. That is, the length of the longitudinal insertion post 54 is less than the lengths of the first and second insertion posts, and the lengths of the first and second insertion posts are the same. In this way, the large-sized and integrally formed first and second insertion posts are on both sides, and the longitudinal insertion post 54 is in the middle, which can avoid improper damage to the longitudinal insertion post 54 during docking.

[0038] Both the first and second power terminals 61 and 62 are elastic terminals and have substantially the same structure. The first power terminal 61 includes a frame-shaped portion 611, two first elastic arms 612 and two second elastic arms 613 extending forward from the frame-shaped portion, and a connecting portion 614. The two first elastic arms 612 are opposite to each other and are both provided with rear contact portions (not labeled). The two second elastic arms 612 are opposite to each other and are both provided with front contact portions (not labeled). The front contact portions are located in front of the rear contact portions. The four elastic arms form a contact channel 615 for the insertion of the pin terminal. The front contact portion provides an arc discharge function, and the rear contact portion provides the main electrical connection performance. When the pin terminal is inserted, the contact portion of the pin terminal first contacts the front contact portion and first performs arc discharge. Subsequently, the contact portion of the pin terminal elastically abuts against the rear contact portion to achieve electrical connection.

[0039] The first power terminal 61 is further provided with two L-shaped portions 616. The trailing edge of each L-shaped portion is integrally connected to the leading edge of the front contact portion. In this way, the two L-shaped portions 616 form an entrance portion, and the entrance portion communicates with the contact channel 615 with each other.

[0040] The signal terminal 63 is also an elastic terminal, which includes a U-shaped portion 631, a horizontal portion 632 and two elastic arms 633 extending forward from the U-shaped portion, and a connecting portion 634. The two elastic arms have contact portions. The contact portions of the signal terminals of the socket connector are inserted between the two elastic arms and contact the contact portions, thereby achieving electrical connection.

[0041] The first and second insertion posts 52 and 53 are each provided with terminal holes 522 and 532, and the first and second power terminals are inserted and fixed in the corresponding terminal holes. The longitudinal insertion post 54 is provided with a plurality of terminal holes 543, and the signal terminals are inserted and fixed in the terminal holes. The connecting portions 614 of the first and second power terminals are connected to power supply cables (not shown), and the connecting portion 634 of the signal terminal is connected to a signal cable (not shown).

[0042] As shown Figure 10 in the figure, the socket connector 100 and the plug connector 200 are docked with each other. The insulating body 11 of the socket connector has a docking surface 110, and the first and second jacks 12 and 13 and the long slot 14 are recessed from the docking surface 110. The recessed depths of the first and second jacks 12 and 13 are the same, and the recessed depth of the long slot 14 is less than the recessed depths of the first and second jacks. The inner bottom surface 144 of the long slot is closer to the docking surface 110 than the inner bottom surfaces 124 of the first and second jacks. Further, the front ends 234 of the signal terminals 23 are closer to the docking surface 110 than the front ends 214 and 224 of the first and second power terminals, as shown by the dashed line L2.

[0043] The front ends 521 and 531 of the first and second insertion posts 52 and 53 of the plug connector are aligned with each other in the second direction, and the front end 541 of the signal insertion post 54 is located behind the front ends of the first and second insertion posts. In this way, the longitudinal insertion post 54 can be better protected. In some embodiments, the contact between the socket power terminal and the plug power terminal precedes the contact between the socket signal terminal and the plug signal terminal. Each row of power terminals includes six power terminals, and each row of signal terminals includes six signal terminals.

[0044] Figure 11-12 The socket connector 100B of the second embodiment is shown, which is a vertical connector. After the socket connector 100 is installed on a circuit board, its docking direction is perpendicular to the circuit board. The signal terminals 23 are arranged between two rows of power terminals 21 and 22.

[0045] Figure 13-14 The socket connector 100C of the third embodiment is shown, which is a corner connector. In this embodiment, each row of power terminals includes three power terminals, and each row of signal terminals includes three signal terminals.

[0046] Figure 15-17 The socket connector 100D of the fourth embodiment is shown, which is a vertical connector. In this embodiment, each row of power terminals includes three power terminals, and each row of signal terminals includes three signal terminals.

[0047] As can be seen from the above embodiments, in general or the best implementation, the socket connector is composed of two rows of power terminals, and one or two rows of signal terminals are located between the two rows of power terminals. The number of each power terminal can be extended from two to multiple. In some other embodiments, the power terminal rows on both sides of the signal terminal row can be extended to multiple rows, such as two rows of power terminals on each side. In the power terminal arrangement of M*N matrix arrangement, when M is greater than N, the direction of the row is defined by M. For example, in the power terminals of 2*3 matrix arrangement, each row of power terminals includes three power terminals. For example, in the 2*2 matrix arrangement, one row of power terminals can be defined as the direction of the row.

[0048] In summary, the above are only the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention should still be within the scope covered by the patent of the present invention.
