[0035] In the embodiments of this application, reference is made to Figures 1 to 8 This application provides a board-end connector 100, which has a first direction X, a second direction Z, and a third direction Y that intersect each other in pairs. Exemplarily, in this application, the board-end connector 100 has a first direction X, a second direction Z, and a third direction Y that are perpendicular to each other in pairs. Here, "perpendicular" refers to a state where the angle formed by a line and a line, a line and a surface, or a surface and a surface is 89° to 91°.

[0036] Specifically, refer to Figures 1 to 3 The board-end connector 100 includes: a housing 110, a shield 120, a signal terminal 130, and a power terminal 140.

[0038] The signal terminal 130 includes a first signal section 131 and a second signal section 132 that are connected to each other. The first signal section 131 extends along a first direction X, and the second signal section 132 extends along a second direction Z. The first signal section 131 and the second signal section 132 are designed at an angle to each other. For example, in this application, the first signal section 131 and the second signal section 132 are designed perpendicular to each other.

[0039] The power terminal 140 includes a first electrical connection portion 141 and a second electrical connection portion 142 interconnected with each other. The first electrical connection portion 141 extends along a first direction X and is at least partially disposed within a receiving cavity 111. The second electrical connection portion 142 extends along a second direction Z and is located outside the housing 110. The first electrical connection portion 141 and the second electrical connection portion 142 are designed at an angle to each other. Exemplarily, in this application, the first electrical connection portion 141 and the second electrical connection portion 142 are designed perpendicularly to each other. The power terminal 140 is used to transmit electrical energy. Exemplarily, one end of the power terminal 140 is electrically connected, and the other end of the power terminal 140 is electrically connected to an electrical component to supply power to the electrical component.

[0040] The housing 110 is made of plastic, but is not limited to plastic.

[0041] The shielding element 120 is made of metal, for example, a zinc alloy, but is not limited thereto.

[0042] The signal terminal 130 may be made of any one of copper alloy, tin alloy and brass, but is not limited to this.

[0043] The power terminal 140 may be made of any of the following materials: copper alloy, tin alloy and brass, but is not limited thereto.

[0044] The first signal unit 131 and the second signal unit 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first signal unit 131 and the second signal unit 132 can be separately configured and fixedly connected, for example, the second signal unit 132 can be fixedly connected to the first signal unit 131 via welding or riveting. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first signal unit 131 and the second signal unit 132 are integrally die-cast.

[0045] The first electrical connection portion 141 and the second electrical connection portion 142 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first electrical connection portion 141 and the second electrical connection portion 142 can be separately configured and fixedly connected, for example, by welding or riveting. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first electrical connection portion 141 and the second electrical connection portion 142 are integrally die-cast.

[0046] Specifically, the number of signal terminals 130 is n, and the number of power terminals 140 is N, satisfying that n < N, and n is an integer not less than 1. That is, in the board-end connector 100, the number N of power terminals 140 is greater than the number n of signal terminals 130.

[0047] The number n of signal terminals 130 and the number N of power terminals 140 can be directly observed after disassembling the actual board-end connector 100.

[0048] Understandably, this application simultaneously provides signal terminals 130 and power terminals 140 in the board-end connector 100, using signal terminals 130 for signal transmission and power terminals 140 for power supply, thereby enabling the board-end connector 100 to simultaneously perform signal transmission and power supply functions, thus improving the overall performance of the board-end connector 100. Furthermore, this application limits the number of power terminals 140 (N) to be greater than the number of signal terminals 130 (n), thereby limiting the quantitative relationship between signal terminals 130 and power terminals 140. This ensures that the power supply function of the board-end connector 100 is improved without affecting its signal transmission function, further enhancing the overall performance of the board-end connector 100. Additionally, the modular design of the components in this application reduces the space occupied by the board-end connector 100 and lowers production costs.

[0049] In some embodiments, the number n of signal terminals 130 and the number N of power terminals 140 further satisfy: N / n = 2, where n is an integer not less than 1. That is, the number N of power terminals 140 is twice the number n of signal terminals 130, to further limit the quantitative relationship between signal terminals 130 and power terminals 140, so as to further ensure that the power supply function of board-end connector 100 is improved without affecting the signal transmission function of board-end connector 100, and to further improve the overall performance of board-end connector 100.

[0050] For example, in this application, the number n of signal terminals 130 is 2 and the number N of power terminals 140 is 4, but it is not limited thereto.

[0051] In some embodiments, refer to Figures 3 to 6 The shielding component 120 includes a first shielding part 121 and a second shielding part 122 that are connected to each other. The first shielding part 121 has a first sub-cavity 1231 and a second sub-cavity 1232. The first sub-cavity 1231 extends along a first direction X, and the second sub-cavity 1232 extends along a second direction Z. The first sub-cavity 1231 and the second sub-cavity 1232 are connected to form a shielding cavity 123.

[0052] The first shielding part 121 and the second shielding part 122 can be integrally formed, that is, the first shielding part 121 and the second shielding part 122 are a single-piece structure. Alternatively, the first shielding part 121 and the second shielding part 122 can be separately arranged and fixedly connected, for example, the second shielding part 122 can be fixedly connected to the first shielding part 121 by welding or riveting. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first shielding part 121 and the second shielding part 122 are integrally die-cast.

[0053] Specifically, refer to Figures 4 to 6 The first signal section 131 is disposed in the first sub-cavity 1231, and the second signal section 132 is disposed in the second sub-cavity 1232, so as to ensure the shielding effect of the shielding component 120, ensure that the shielding component 120 effectively shields the external electromagnetic waves from interfering with the signal terminal 130, prevents crosstalk between different signal terminals 130, maintains the integrity and stability of the signal, and protects the signal terminal 130 from damage by mechanical, electromagnetic or environmental factors. It effectively guides and disperses the charge or current on the signal terminal 130, thereby reducing voltage fluctuations of the signal line and improving the anti-interference capability and signal stability of the board connector 100.

[0054] In some embodiments, refer to Figures 4 to 6 The housing 110 includes a main body 112 and a first fixing part 113, the first fixing part 113 being connected to one side of the main body 112 in the first direction Z.

[0055] The main body 112 and the first fixing part 113 can be integrally molded, meaning they are a single-piece structure. Alternatively, the main body 112 and the first fixing part 113 can be separately configured and fixedly connected, for example, the first fixing part 113 can be fixedly connected to the main body 112 by bonding or riveting. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the main body 112 and the first fixing part 113 are integrally injection molded.

[0056] Specifically, the first fixing part 113 has a first through hole 1131, which communicates with the receiving cavity 111. The first shielding part 121 passes through the first through hole 1131 to initially limit the first shielding part 121, thereby initially positioning the shielding member 120, preventing the shielding member 120 from moving freely, improving the overall structural stability of the board end connector 100, and ensuring the normal use of the board end connector 100.

[0057] In some embodiments, refer to Figures 4 to 6 The first shielding part 121 has a slot 1211; the housing 110 also includes a latching part 114, which is disposed on the first fixing part 113 and latches into the slot 1211. The two form a latching and fixing structure, so as to further position and fix the shielding part 120 by utilizing the cooperation between the latching part 114 and the slot 1211, further preventing the shielding part 120 from moving freely, improving the overall structural stability of the board end connector 100, and ensuring the normal use of the board end connector 100.

[0058] In some embodiments, refer to Figures 4 to 6 The board-end connector 100 further includes an insulating element 150, which is disposed in the shielding cavity 123 and is used to insulate the shielding element 120 from the signal terminal 130.

[0059] The insulating element 150 may be made of an insulating material. For example, in this application, the insulating element 150 may be made of silicone or rubber. However, it is not limited to this.

[0060] The outer contour dimension of the insulating component 150 is larger than the inner contour dimension of the shielding cavity 123, that is, the fit between the insulating component 150 and the shielding component 120 is an interference fit, thereby ensuring the tight assembly between the insulating component 150 and the shielding component 120, ensuring the overall structural stability of the board-end connector 100, and ensuring the effective and high-speed transmission of signals in the board-end connector 100.

[0061] Specifically, the insulating member 150 includes: a first insulating part 151 and a second insulating part 152 connected to each other. The first insulating part 151 extends along a first direction X and is sleeved on the outer surface of the first signal part 131. The second insulating part 152 extends along a second direction Z and is sleeved on the outer surface of the second signal part 132.

[0062] The first insulating part 151 and the second insulating part 152 can be integrally molded, that is, the first insulating part 151 and the second insulating part 152 are a one-piece structure. Alternatively, the first insulating part 151 and the second insulating part 152 can be separately disposed, but fixedly connected, for example, the second insulating part 152 can be fixedly connected to the first insulating part 151 by bonding or riveting. This application does not impose specific limitations, and the specific configuration can be determined according to actual circumstances. For example, in this application, the first insulating part 151 and the second insulating part 152 are integrally injection molded.

[0063] This application provides insulation between the signal terminal 130 and the shield 120 by sleeved a first insulating part 151 on the outer surface of the first signal part 131 and a second insulating part 152 on the outer surface of the second signal part 132, thereby preventing the signal terminal 130 and the shield 120 from coming into contact with each other and causing signal crosstalk, thus ensuring effective and high-speed signal transmission.

[0064] In some embodiments, at least two shielding cavities 123 are provided, and each shielding cavity 123 is separated from the others; at least two signal terminals 130 are provided, and each signal terminal 130 is respectively provided in a corresponding shielding cavity 123.

[0065] Specifically, at least two power terminals 140 are provided, and multiple power terminals 140 are installed in the housing 110. The first electrical connection portions 141 of the multiple power terminals 140 are arranged at intervals along the second direction Z and the third direction Y, respectively, and the second electrical connection portions 142 of the multiple power terminals 140 are arranged at intervals along the first direction X and the third direction Y, respectively.

[0066] This application sets up multiple signal terminals 130 and multiple power terminals 140 to form multiple signal connection channels and circuit connection channels in a small space in the board-end connector 100, thereby realizing the transmission of multiple signals and the power supply of multiple electrical components. This realizes the integrated function of the board-end connector 100, reduces the space occupied by the connector 100, and ensures that the board-end connector 100 can be applied to different application scenarios, giving the board-end connector 100 good compatibility and flexibility.

[0067] In some embodiments, different signal terminals 130 can be electrically connected to different external wiring harnesses to enable the board-end connector 100 to transmit and receive signals for different application scenarios and technical standards, thus giving the board-end connector 100 good compatibility and flexibility.

[0068] Different power terminals 140 can be electrically connected to different external electrical components to supply power to different external electrical components, giving the board-end connector 100 good compatibility and flexibility.

[0069] In some embodiments, refer to Figures 4 to 6 The board-end connector 100 also includes a separator 160, which is disposed in the shielding cavity 123, is fixedly connected to the shielding member 120, and is located between two adjacent second signal sections 132.

[0070] The separator 160 may be made of zinc alloy, but is not limited to this.

[0071] In this application, the shielding member 120 has a fixing groove (not shown in the figure), and the partition member 160 is detachably connected to the fixing groove to achieve a fixed connection between the partition member 160 and the shielding member 120.

[0072] Understandably, in order to facilitate the assembly of multiple signal terminals 130 and ensure the overall assembly efficiency of the board connector 100, multiple second sub-cavities 1232 in the shield 120 are interconnected to facilitate the assembly of multiple signal terminals 130. However, this structural design may affect the shielding effect of the shield 120.

[0073] This application provides a separator 160 in the shield 120, with the separator 160 located between two adjacent second signal sections 132, to shield and separate the two adjacent second signal sections 132, preventing crosstalk between different signal terminals 130, thus maintaining signal integrity and stability, while protecting the signal terminals 130 from damage by mechanical, electromagnetic, or environmental factors, effectively guiding and dispersing the charge or current on the signal terminals 130, thereby reducing voltage fluctuations in the signal line and improving the anti-interference capability and signal stability of the board connector 100.

[0074] In some embodiments, refer to Figure 4 , Figures 7 to 8 The housing 110 further includes a second fixing part 115, which is connected to one side of the main body 112 in the first direction Z, and the second fixing part 115 and the first fixing part 113 are arranged at intervals in the third direction Y. The second fixing part 115 is provided with a second through hole 1151, which communicates with the receiving cavity 111.

[0075] The main body 112 and the second fixing part 115 can be integrally molded, meaning they are a single, integrated structure. Alternatively, the main body 112 and the second fixing part 115 can be separately configured and fixedly connected, for example, by bonding or riveting the second fixing part 115 to the main body 112. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the main body 112 and the second fixing part 115 are integrally injection molded.

[0076] Specifically, the power terminal 140 also includes a limiting protrusion 143, which protrudes from the outer wall of the first electrical connection portion 141. The first electrical connection portion 141 passes through the second through hole 1151, and the limiting protrusion 143 is located inside the second through hole 1151. The outer contour dimension of the limiting protrusion 143 is larger than the inner contour dimension of the second through hole 1151. That is, the fit between the power terminal 140 and the housing 110 is an interference fit, thereby ensuring the tight assembly between the power terminal 140 and the housing 110, further ensuring the overall structural stability of the board connector 100, and ensuring the stable power supply of the power terminal 140 in the board connector 100.

[0077] In some embodiments, a second through hole 1151 is provided on the second fixing part 115, and the first electrical connection part 141 of each power terminal 140 passes through a corresponding second through hole 1151.

[0078] On the other hand, in the embodiments of this application, this application also provides a vehicle, including: a board-end connector 100 as in any of the above embodiments, the board-end connector 100 being used for signal transmission between different electrical components in the vehicle and for supplying power to the electrical components.
