[0032] In the embodiments of this application, reference is made to Figures 1 to 6 This application provides a board-end connector 100, which has a first direction X, a second direction Y, and a third direction Z that intersect each other in pairs. Exemplarily, in this application, the board-end connector 100 has a first direction X, a second direction Y, and a third direction Z 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°.

[0033] Specifically, refer to Figures 1 to 2 The board-end connector 100 includes: a housing 110, a shield 120, a signal connector 130, and an electrical connector 140.

[0034] Specifically, the housing 110 is provided with a receiving cavity 111; the shielding member 120 is installed on one side of the housing 110 in the first direction X, and at least a portion of the shielding member 120 is disposed in the receiving cavity 111. Specifically, in this application, a portion of the shielding member 120 is disposed in the receiving cavity 111, and another portion of the shielding member 120 is disposed outside the receiving cavity 111. The shielding member 120 has a shielding cavity 121; the signal connector 130 extends along the first direction X, that is, the signal connector 130 is generally linear. At least a portion of the signal connector 130 is disposed within the shielding cavity 121. Specifically, in this application, a portion of the signal connector 130 is disposed within the shielding cavity 121, and another portion is disposed outside the shielding cavity 121. The signal connector 130 is insulated from the shielding member 120, and the signal connector 130 is used to transmit signals, that is, the signal connector 130 is used to realize signal transmission between different electrical components. The electrical connector 140 extends along the first direction X, that is, the electrical connector 140 is generally linear. Furthermore, at least a portion of the electrical connector 140 is disposed within the receiving cavity 111. Specifically, in this application, a portion of the electrical connector 140 is disposed within the receiving cavity 111, while another portion is disposed outside the receiving cavity 111. The electrical connector 140 is used to transmit electrical energy. Exemplarily, one end of the electrical connector 140 is electrically connected, and the other end of the electrical connector 140 is electrically connected to an electrical component to supply power to the electrical component.

[0035] The housing 110 is made of plastic, but is not limited to plastic.

[0036] The shielding element 120 is made of metal, for example, a zinc alloy, but is not limited thereto.

[0037] The signal connector 130 may be made of any one of copper alloy, tin alloy and brass, but is not limited to this.

[0038] Electrical connector 140 may be made of any of the following materials: copper alloy, tin alloy, and brass, but is not limited thereto.

[0039] Specifically, the number of signal connectors 130 is n1, and the number of electrical connectors 140 is n2, satisfying: n1 < n2, and n1 is not less than an integer of 1. That is, in the board-end connector 100, the number of electrical connectors 140 n2 is greater than the number of signal connectors 130 n1.

[0040] The number of signal connectors 130 (n1) and electrical connectors 140 (n2) can be directly observed after disassembling the actual board-end connector 100.

[0041] Understandably, this application simultaneously provides signal connectors 130 and electrical connectors 140 in the board-end connector 100, using signal connectors 130 for signal transmission and electrical connectors 140 for power supply. This allows the board-end connector 100 to simultaneously perform signal transmission and power supply functions, improving the overall performance of the board-end connector 100 and ensuring its applicability to different application scenarios, thus providing good compatibility and flexibility. Furthermore, this application limits the quantity relationship between signal connectors 130 and electrical connectors 140 by ensuring that the power supply function of the board-end connector 100 is improved without affecting its signal transmission function, further enhancing its overall performance. Additionally, the modular design of each component in this application reduces the space occupied by the board-end connector 100 and lowers production costs.

[0042] In some embodiments, the number n1 of signal connectors 130 and the number n2 of electrical connectors 140 further satisfy: n2 / n1 = 2, where n1 is an integer not less than 1. That is, the number n2 of electrical connectors 140 is twice the number n1 of signal connectors 130. This further limits the quantitative relationship between signal connectors 130 and electrical connectors 140, thereby further ensuring that the power supply function of the board connector 100 is improved without affecting the signal transmission function of the board connector 100, and further improving the overall performance of the board connector 100.

[0043] In some embodiments, refer to Figure 2 The housing 110 includes a first sidewall 112 and a second sidewall 113. The first sidewall 112 extends along a first direction X, and the second sidewall 113 is connected to one side of the first sidewall 112 in the first direction X. The first sidewall 112 and the second sidewall 113 together form a receiving cavity 111.

[0044] Specifically, a first through hole 1131 is provided on the second sidewall 113, and a first positioning part 1132 is provided on the second sidewall 113, the first positioning part 1132 being located inside the first through hole 1131; a first positioning groove 122 is provided on one side of the shield 120 in the second direction Y, the shield 120 passing through the first through hole 1131, and the first positioning part 1132 being embedded in the first positioning groove 122, the two forming a positioning and fixing structure, so as to use the cooperation between the first positioning part 1132 and the first positioning groove 122 to position and fix the shield 120, prevent the shield 120 from moving freely, improve the overall structural stability of the board end connector 100, and ensure the normal use of the board end connector 100.

[0045] The first sidewall 112 and the second sidewall 113 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first sidewall 112 can be separately disposed from the second sidewall 113, with a fixed connection between them, for example, the second sidewall 113 can be fixedly connected to the first sidewall 112 via a snap-fit ​​or similar process. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first sidewall 112 and the second sidewall 113 are integrally injection molded.

[0046] The first positioning part 1132 and the first positioning groove 122 can be of any shape. For example, in the application, both the first positioning part 1132 and the first positioning groove 122 are polygonal, but are not limited thereto.

[0047] In some embodiments, refer to Figure 2 The board-end connector 100 also includes an insulating member 150, which is disposed inside the shielding cavity 121 and sleeved on the outer surface of the signal connector 130 to insulate the signal connector 130 from the shielding member 120, thereby preventing the signal connector 130 and the shielding member 120 from contacting each other and causing signal crosstalk, and ensuring effective and high-speed signal transmission.

[0048] 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.

[0049] In one embodiment, the outer contour dimension of the insulating member 150 is larger than the inner contour dimension of the shielding cavity 121, that is, the fit between the insulating member 150 and the shielding member 120 is an interference fit, thereby ensuring the tight assembly between the insulating member 150 and the shielding member 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.

[0050] In some embodiments, refer to Figure 4 The shielding component 120 has a second positioning groove 123, which is located on one side of the shielding cavity 121 in the second direction Y, and the second positioning groove 123 is connected to the shielding cavity 121.

[0051] Specifically, the insulating component 150 includes an insulating body 151 and a second positioning part 152. The second positioning part 152 protrudes from the outer wall surface of the insulating body 151 and is embedded in the second positioning groove 123. The two form a positioning and fixing structure, so that the fastening assembly between the insulating component 150 and the shielding component 120 can be further realized through the cooperation between the second positioning part 152 and the second positioning groove 123, which further ensures the overall structural stability of the board-end connector 100 and further ensures the effective and high-speed transmission of signals in the board-end connector 100.

[0052] The insulating body 151 and the second positioning part 152 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the insulating body 151 and the second positioning part 152 can be separately configured and fixedly connected, for example, the second positioning part 152 can be fixedly connected to the insulating body 151 via a snap-fit ​​or similar process. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the insulating body 151 and the second positioning part 152 are integrally injection molded.

[0053] The second positioning part 152 and the second positioning groove 123 can be of any shape. For example, in this application, both the second positioning part 152 and the second positioning groove 123 are polygonal, but are not limited thereto.

[0054] In some embodiments, refer to Figure 5 The insulating body 151 has a second through hole 1511 and a limiting groove 1512, with the limiting groove 1512 located on the side of the second through hole 1511 in the third direction Z.

[0055] Specifically, the signal connector 130 includes a first connecting portion 131 and a first protrusion 132. The first connecting portion 131 extends along the first direction X, and the first protrusion 132 protrudes from the outer wall surface of the first connecting portion 131. The first connecting portion 131 passes through the second through hole 1511, and the first protrusion 132 is embedded in the limiting groove 1512. The two form a limiting and fixing structure, so that the fast assembly between the insulating member 150 and the signal connector 130 can be achieved through the cooperation between the first protrusion 132 and the limiting groove 1512, which further ensures the overall structural stability of the board connector 100 and further ensures the effective and high-speed transmission of signals in the board connector 100.

[0056] The first connecting portion 131 and the first protrusion 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first connecting portion 131 and the first protrusion 132 can be separately configured and fixedly connected, for example, the first protrusion 132 can be fixedly connected to the first connecting portion 131 via a snap-fit ​​or similar process. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first connecting portion 131 and the first protrusion 132 are integrally die-cast.

[0057] In some embodiments, refer to Figures 1 to 2 The shield 120 is provided with a plurality of positioning protrusions 124 on the side away from the housing 110 in the first direction X, so that when the board connector 100 is used in the vehicle, the positioning protrusions 124 can be used in conjunction with other structures to position and fix the board connector 100, ensuring the normal use of the board connector 100.

[0058] In some embodiments, refer to Figure 6 A third through hole 1133 is provided on the second side wall 113.

[0059] Specifically, the electrical connector 140 includes a second connecting portion 141 and a second protrusion 142. The second protrusion 142 protrudes from the outer wall surface of the second connecting portion 141. The second connecting portion 141 passes through the third through hole 1133. The second protrusion 142 is located inside the third through hole 1133, and the outer contour dimension of the second protrusion 142 is larger than the inner contour dimension of the third through hole 1133. That is, the fit between the electrical connector 140 and the housing 110 is an interference fit, thereby ensuring the tight assembly between the electrical connector 140 and the housing 110, further ensuring the overall structural stability of the board-end connector 100, and ensuring the stable power supply of the electrical connector 140 in the board-end connector 100.

[0060] The second connecting portion 141 and the second protrusion 142 can be integrally formed, meaning they are a single, one-piece structure. Alternatively, the second connecting portion 141 and the second protrusion 142 can be separately disposed, but fixedly connected, for example, the second protrusion 142 can be fixedly connected to the second connecting portion 141 via a snap-fit ​​or similar process. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the second connecting portion 141 and the second protrusion 142 are integrally die-cast.

[0061] In some embodiments, refer to Figure 6 The second protrusion 142 has a guide wall 1421, which is inclined relative to the first direction X. By providing the guide wall 1421, this application enables the electrical connector 140 to be guided during assembly, thereby facilitating the assembly of the electrical connector 140 and improving the overall assembly efficiency of the board-end connector 100.

[0062] 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.
