Description

Technical Field

[0001] This utility model relates to a power connector. Background Technology

[0002] Chinese invention patent application CN113629420A provides a board-end connector and a wire-end connector, which can be interlocked to form a wire-to-board connector assembly. The wire-end connector includes a wire-end insulating housing, multiple wire-end power terminals, and multiple wire-end signal terminals. The wire-end insulating housing has a wire-end power insertion portion and a wire-end signal insertion portion, with the signal insertion portion located on one side of the power insertion portion. Multiple wire-end terminals are housed within the power insertion portion. Multiple wire-end signal terminals are housed within the signal insertion portion. Compared to known separate power and signal transmission connection methods, this combines power and signal transmission methods, simplifying the connection process and saving space, conforming to current miniaturization design trends.

[0003] However, due to the uneven distribution of power connector terminals, uneven force can easily damage the signal terminals during insertion. Furthermore, in high-current parallel applications, uneven current distribution can easily cause heat generation and quality issues. Therefore, it is desirable to design an improved power connector.

[0015] Component Symbol Explanation Power connector 200 Insulating body 50 Base 51 Fixing slot 511 First insert 52 Front end 521 First terminal hole 522 Second insert 53 Front end 531 Second terminal hole 532 Longitudinal insertion post 54 front end 541 Mounting rib 542 Terminal hole 543 Fixed recess 545 515 bump Clamping arm 55 Front end 551 First power terminal 61 Frame type part 611 First elastic arm 612 Second elastic arm 613 Connecting part 614 Contact Channel 615 L-shaped section 616 Second power terminal 62 Signal terminal 63 U-shaped part 631 Horizontal part 632 Elastic arm 633 Connecting part 634 Cable 70 First power cable 71 Second power cable 72 Signal cable 73 Specific implementation mode Refer to Figure 1-8 , which shows the power connector 200 of the present utility model, which is adapted to be mated with a socket connector (not shown) that can be docked. The power connector 200 includes an insulating body 50, a plurality of first power terminals 61, a plurality of second power terminals 62, a plurality of signal terminals 63, and a cable 70 held in the insulating body 50.

[0016] The plurality of first power terminals 61 are arranged in a row along the first direction (the horizontal direction shown in the drawing), the plurality of second power terminals 62 are arranged in a row along the first direction, and the plurality of signal terminals 63 are located between the first power terminal row and the second power terminal row in the second direction (the vertical direction shown in the drawing). The first direction and the second direction are perpendicular to each other. The two rows of power terminals 61 and 62 are located on both sides of the signal terminal 63. This avoids damage to the signal terminal 63 during improper insertion. At the same time, the relative arrangement of a row of first power terminals 61 and a row of second power terminals 62 is adjacent. In this application, a row of first power terminals 61 and a row of second power terminals 62 are respectively located on both sides of the signal terminal 63, which can provide more space for the power terminals to dissipate heat.

[0017] The insulating body 50 includes a base 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 51. Each of the first insertion posts 52 is provided with a first terminal hole 522, and each of the second insertion posts 53 is provided with a second terminal hole 532. The longitudinal insertion post 54 is provided with a plurality of terminal holes 543. The first power terminals 61 are respectively arranged in the first insertion posts 52, the second power terminals 62 are respectively arranged in the second insertion posts 53, and a plurality of signal terminals 63 are arranged in the longitudinal insertion post 54. The first and second power terminals 62 are inserted and fixed in the corresponding terminal holes. The signal terminals 63 are inserted and fixed in the terminal holes 543. In this embodiment, when viewed from the docking direction (as Figure 3 shown), the plurality of first terminal holes 522 have different inscribed angles to be applicable to different application scenarios and avoid misinsertion of different systems; similarly, the plurality of second terminal holes 532 have different inscribed angles, and the first and second terminal holes are also asymmetric.

[0018] The first insertion post 52 and the second insertion post 53 are integrally formed extending from one surface of the base 51. The longitudinal insertion post 54 is assembled and fixed to the base 51. That is, the plurality of first insertion posts 52 and the plurality of second insertion posts 53 are integrally formed with the base 51, and the longitudinal insertion post 54 is assembled to the base 51. This facilitates the forming of the insulating body 50. The base 51 is provided with a fixing groove 511 that extends 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. Furthermore, the mounting rib is provided with a fixing recess 545, and the base 51 is provided with a protrusion 515 that mates with the fixing recess.

[0019] The base 51 has a retaining arm 55 integrally provided near the first insertion post 52. (See reference...) Figure 1 As shown, the front end 541 of the longitudinally elongated pin 54 is located behind the front end 521 of the first pin 52. The front end 551 of the retaining arm 55 is located behind the front end 541 of the longitudinally elongated pin 54. That is, the length of the longitudinally elongated pin 54 extending in the mating direction is less than the lengths of the first pin 52 and the second pin 53, and the lengths of the first pin 52 and the second pin 53 are the same. Thus, with the large-sized and integrally formed first pin 52 and the second pin 53 on both sides and the longitudinally elongated pin 54 in the middle, the longitudinally elongated pin 54 can be better protected, avoiding improper damage to the longitudinally elongated pin 54 during mating. During the mating process with the mating socket connector, the power terminals first contact the signal terminals and the terminals of the socket connector. Each row of power terminals includes six power terminals, and each row of signal terminals includes six signal terminals 63.

[0020] The first power terminal 61, the second power terminal 62, and the third power terminal 62 are all resilient terminals with largely the same structure, and their dimensions are larger than those of the signal terminal 63. The first power terminal 61 includes a frame-shaped portion 611, two first resilient arms 612 extending forward from the frame-shaped portion 611, two second resilient arms 613, and a connecting portion 614 located at the rear of the frame-shaped portion 611. The two first resilient arms 612 are opposite each other and each has a rear contact portion (unlabeled), and the two second resilient arms 612 are opposite each other and each has a front contact portion (unlabeled), with the front contact portion located in front of the rear contact portion. The four resilient arms form a contact channel 615 for the insertion of the power terminal of the socket connector. The front contact portion provides an arc discharge function, and the rear contact portion provides the main electrical connection performance. When the terminal of the socket connector is inserted, the contact portion of the pin-shaped terminal first contacts the front contact portion to perform an arc discharge, and then elastically abuts against the rear contact portion to achieve an electrical connection.

[0021] The first power terminal 61 is further provided with two L-shaped portions 616, the rear edge of each L-shaped portion being integrally connected to the front edge of the front contact portion, so that the two L-shaped portions 616 constitute an entrance portion, and the entrance portion is connected to the contact channel 615.

[0022] The signal terminal 63 is also a flexible terminal, which includes a U-shaped portion 631, a horizontal portion 632 extending forward from the U-shaped portion, two spring arms 633, and a connecting portion 634 located at the rear of the U-shaped portion 631. The two spring arms 633 have contact portions. The contact portion of the corresponding signal terminal of the socket connector is inserted between the two spring arms and contacts the contact portion, thereby achieving an electrical connection.

[0023] The cables include a plurality of first power cables 71, a plurality of second power cables 72, and a plurality of signal cables 73. Each first power terminal 61 has a connection portion 614 mechanically and electrically connected to a single first power cable 71, each second power terminal 62 has a connection portion 614 mechanically and electrically connected to a single second power cable 72, and each signal terminal 63 has a connection portion 634 mechanically and electrically connected to a single signal cable.

[0024] The first power cable 71 and the second power cable 72 are identical cables. Taking the first power cable 71 as an example, each first power cable 71 includes multiple inner conductors (unlabeled) and an insulating outer sheath (unlabeled) covering the inner conductors. The signal cable 73 includes a signal inner conductor (unlabeled) and an insulating outer sheath (unlabeled) covering the signal inner conductor. Both the power cable and the signal cable 73 are multi-core wires. Specifically, each first power cable 71 has at least 100 inner conductors. Specifically, each signal cable 73 has at least 10 inner conductors. The cross-sectional dimension of the first power cable 71 is larger than that of the signal cable 73. The wire diameter of the first power cable 71 is at least 5 times the wire diameter of the signal cable 73. The cross-sectional area of ​​the first power cable 71 is at least 30 times that of the cross-sectional area of ​​the signal cable 73. Specifically, the signal cable 73 is a US gauge 28 AWG cable, and the first power cable 71 and the second power cable 72 are US gauge 12 AWG cables. In other embodiments, the plurality of first power cables 71 are connected as one unit in a first direction, and the plurality of second power cables 72 are connected as one unit in a first direction, and the plurality of signal cables 73 are connected as one unit in a first direction.

[0025] In this embodiment, the first power terminal 61, signal terminal 63, and second power terminal 62 are aligned one-to-one in the vertical direction. The spacing between adjacent first power terminals 61 is 3 mm, the spacing between adjacent second power terminals 62 is 3 mm, and the spacing between adjacent signal terminals 63 is 3 mm. Thus, the spacing of the signal terminals 63 is the same as the spacing of the power terminals. In some other embodiments, the spacing between adjacent first power terminals 61 along the first direction is the same as the spacing between adjacent second power terminals 62 along the first direction, but the spacing between adjacent signal terminals 63 along the first direction is less than or greater than the spacing between adjacent first power terminals along the first direction. In other embodiments, the spacing between adjacent power terminals can be 2.5 mm, 3.5 mm, or 5.7 mm to accommodate power transmission of different amperes.

[0026] As can be seen from the above embodiments, in general or the preferred implementation, the power connector consists of two rows of power terminals, with one or two rows of signal terminals located between the two rows of power terminals. The number of each power terminal can be expanded from two to multiple. In some other embodiments, the power terminal rows on both sides of the signal terminal row can be expanded to multiple rows, such as two rows of power terminals on each side.

[0027] This utility model discloses a power connector comprising two rows of power terminals and multiple signal terminals, with the signal terminals located between the two rows of power terminals. This arrangement, with the power terminals positioned on either side of the signal terminals, increases the surface area for heat dissipation, thus improving heat dissipation. The power terminals are relatively larger than the signal terminals, and the placement of the two rows of power terminals on either side of the signal terminals prevents damage to the signal terminals during improper insertion. In certain situations, this symmetrical structure allows the power connector to be used without distinguishing between the correct and reverse insertion orientation.
