[0030] This embodiment provides a composite board-end high-current connector, which is composed of a high-power terminal 20, a signal terminal 30 and a low-power terminal 40. It is small in size and easy to assemble in actual use. It does not require a large installation space for installation. In addition, the internal structure of the composite board-end high-current connector of the embodiment is stable, and the conduction and disconnection will not often occur in actual use, ensuring the stable use of the composite board-end high-current connector.

[0031] Combine Figures 1 to 7 As shown, the composite board-end high-current connector of this embodiment includes a connector housing 10 and high-power terminals 20, signal terminals 30 and low-power terminals 40 located in the connector housing 10. The connector formed by the high-power terminals 20, signal terminals 30 and low-power terminals 40 is smaller in size and more convenient to use.

[0032] In this embodiment, the composite board-end high-current connector further includes a PCB board 80 , and the connector is soldered on the PCB board 80 to achieve current and signal control.

[0033] Specifically, the connector housing 10 of this embodiment is provided with a first housing 11, a second housing 12 and a third housing 13, which respectively install the high-power terminal 20, the signal terminal 30 and the low-power terminal 40. A plurality of positioning protrusions 70 are provided on the connector housing 10 to position and install the connector housing 10.

[0034] Combine Figures 1 to 4 As shown, the high-power terminal 20 of this embodiment is installed in the connector housing 10 through the first card point structure 50 and the second card point structure 60. A high-power terminal elastic force arm 21 and a high-power terminal boss 22 are provided on the high-power terminal 20 to install the high-power terminal 20 into the connector housing 10. The first card point structure 50 and the second card point structure 60 can provide a holding force between the high-power terminal 20 and the first housing 11. The high-power terminal elastic force arm 21 can also provide a holding force between the high-power terminal 20 and the first housing 11 to achieve stable installation of the high-power terminal 20. The presence of the high-power terminal boss 22 can effectively prevent the high-power terminal 20 from rotating after assembly.

[0035] In this embodiment, a guide groove 111 is provided in the first shell 11, and the guide groove 111 cooperates with the high-power terminal 20, effectively avoiding fatigue caused by long-term interference fit between the high-power terminal 20 and the first shell 11. A boss groove 112 is provided in the first shell 11, and the boss groove 112 cooperates with the high-power terminal boss 22, effectively avoiding rotation of the high-power terminal 20.

After the signal terminal 30 is installed, the signal terminal elastic force arm 31 rebounds to limit the signal terminal 30 from being unpinned and provides a retaining force between the signal terminal 30 and the second housing 12. The signal terminal boss 32 can accurately position and install the signal terminal 30 and prevent the signal terminal 30 from rotating after being assembled with the second housing 12.

[0037] In this embodiment, a plurality of positioning convex ribs 121 are provided in the second shell 12. The positioning convex ribs 121 cooperate with the signal terminal 30 to position and install the signal terminal 30 and provide retention force. The second shell 12 is provided with a mounting groove 122. The mounting groove 122 cooperates with the signal terminal boss 32 to prevent the signal terminal 30 from rotating after being assembled with the second shell 12.

[0038] Combine Figure 1 and Figure 7 As shown, a low-power terminal elastic force arm 41 is provided on the low-power terminal 40 of this embodiment to install the low-power terminal 40 into the connector housing 10. The low-power terminal elastic force arm 41 of this embodiment is a piercing elastic force arm, which interferes with the side of the third housing 13 to provide a retaining force between the third housing 13.

[0039] In this embodiment, the low-power terminal elastic arm 41 is an arc-shaped structure to position the low-power terminal 40 .

[0040] In actual use, the composite board-end high-current connector of this embodiment is composed of a high-power terminal 20, a signal terminal 30 and a low-power terminal 40. It is small in size and easy to assemble in actual use, and does not require a large installation space for installation. In addition, the internal structure of the composite board-end high-current connector of the embodiment is stable, and in actual use, the conduction and disconnection situation will not often occur, ensuring the stable use of the composite board-end high-current connector.
