[0029] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0030] like Figures 1 to 5 As shown, the present disclosure provides a preferred embodiment of a board-end terminal sealing structure of an intelligent distribution box 100, including an upper shell 10, a board-end terminal 40 and a circuit board 30. The upper shell 10 is provided with an accommodating through cavity 101. The board-end terminal 40 includes a terminal body accommodated in the accommodating through cavity 101 and a terminal pin extending out of the accommodating through cavity 101. The terminal pin is electrically connected to the circuit board 30. A sealing component 50 is provided between the terminal body and the accommodating through cavity 101.

[0031] Thus, the board-side terminal sealing structure of the smart distribution box 100 according to the disclosed embodiment solves the waterproofing problem between the terminal and the upper housing 10 by providing a sealing member 50 between the upper housing 10 and the board-side terminal 40, thereby meeting the higher protection level requirements of the smart distribution box 100. This structural design effectively improves the dust and water resistance of the smart distribution box 100, achieving a protection level of IP69.

[0032] Preferably, the sealing member 50 is a sealing ring.

[0033] Specifically, if Figure 2 As shown, the sealing member 50 can be a bellows seal. In other embodiments not shown, the sealing member 50 can also be an O-ring.

[0034] like Figure 2 and Figure 4 As shown, the terminal body is constructed as a barrel 401 with a central blind hole and internal threads. A bolt 70 is inserted into barrel 401, mating with the internal threads to electrically connect the wiring harness terminal to the board-side terminal 40. The wiring harness terminal can be the positive terminal of a battery or a DC-DC vehicle power supply. This allows the battery or DC-DC vehicle power supply to power the circuit board 30 and the electronic components thereon via the wiring harness terminal and the board-side terminal 40.

[0035] In some embodiments, as Figure 2 As shown, the terminal pins are integrally extended from the bottom of the barrel 401. As a result, the terminal structure has strong stability and good conductive performance.

[0036] In other embodiments, Figure 3 As shown, the terminal pins are connected to the barrel 401 in a split-type connection, thereby saving time and cost for processing the entire terminal, and also enabling subsequent electrical connection to the circuit board 30 to be achieved through the split-type connection.

[0037] Specifically, if Figure 4 As shown, the terminal pin includes a flat plate portion 402 matching the bottom of the barrel 401 , and a connecting portion 403 extending and bending from the flat plate portion 402 , and the connecting portion 403 is electrically connected to the circuit board 30 .

[0038] More specifically, the flat plate portion 402 and the cylindrical body 401 can be connected by welding or riveting. This non-detachable connection ensures the stability of the electrical connection between the board terminal 40 and the circuit board 30.

[0039] In various embodiments, Figure 2 、 Figure 3 and Figure 4 As shown, the extending direction of the connecting portion 403 of the terminal pin electrically connected to the circuit board 30 is offset in parallel with the rotation center axis of the cylinder 401 .

[0040] This facilitates inserting the terminal pins into the circuit board 30 and electrically connecting the terminal pins to the circuit board 30 , such as by soldering.

[0041] In some embodiments, as Figure 5 As shown, a plurality of limiting posts 102 are provided on the mounting surface of the upper shell 10 facing the circuit board 30 , and the plurality of limiting posts 102 are arranged around the accommodating cavity 101 , and a recess is provided on the periphery of the board-end terminal 40 to match the limiting posts 102 .

[0042] Therefore, through the cooperation between the limiting column 102 and the recess, the board-end connecting terminal 40 is more stably installed in the accommodating cavity 101, thereby ensuring the stability of the electrical connection between the board-end connecting terminal 40 and the circuit board 30.

[0043] Another aspect of the present disclosure provides a smart distribution box 100 , comprising the board-end terminal sealing structure of the smart distribution box 100 according to any of the above embodiments.

[0044] The smart power distribution box 100 typically includes an upper housing 10 and a lower housing 20 that interlock. A circuit board 30 is disposed between the upper and lower housings 10 and 20. Multiple board-side terminals 40 are electrically connected to the circuit board 30. Some of these terminals 40 can be connected to the positive terminal of a battery, while others can be connected to the positive terminal of a DC-DC vehicle power supply. The lower housing 20 is grounded, serving as the negative terminal of the power supply. The sealing structure for the board-side terminals within the smart power distribution box 100 has been described in detail above and will not be further elaborated on.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present disclosure.

Thus, if such changes and modifications of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is intended to include such changes and modifications.

[0047] It should also be understood that in the embodiments herein, the term "and / or" merely describes an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" could represent: A alone, A and B simultaneously, or B alone.
