[0032] In the embodiments of this application, reference is made to Figures 1 to 7 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 3 The board-end connector 100 includes: a housing 110, a shield 120, a signal terminal 130, and a power terminal 140.

[0034] Specifically, the housing 110 is provided with a receiving cavity 111; a 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. The shielding member 120 has multiple shielding cavities 121, and the multiple shielding cavities 121 are separated, that is, the multiple shielding cavities 121 are not interconnected; multiple signal terminals 130 are provided, each of the multiple signal terminals 130 extends along the first direction X, and the multiple signal terminals 130 are spaced apart in the second direction Y. Each signal terminal 130 is disposed in a corresponding shielding cavity 121, and each signal terminal 130 is insulated from the shielding member 120. The signal terminals 130 are used to transmit signals, that is, the signal terminals 130 are used to realize signal transmission between different electrical components. Multiple power terminals 140 are provided, each of the multiple power terminals 140 extends along the first direction X, and the multiple power terminals 140 are spaced apart in the second direction Y and / or the third direction Z. Exemplarily, in this application, the multiple power terminals 140 are spaced apart in the second direction Y and the third direction Z, respectively. Each power terminal 140 is partially disposed within the receiving cavity 111, and the power terminal 140 is used to transmit electrical energy. For example, 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.

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

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

[0039] Understandably, this application simultaneously provides signal terminals 130 and power terminals 140 in the board-end connector 100, using the signal terminals 130 for signal transmission and the power terminals 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. Furthermore, by providing multiple signal terminals 130 and multiple power terminals 140, this application forms multiple signal connection channels and circuit connection channels within a relatively small space in the board-end connector 100, enabling the transmission of multiple signals and the power supply of multiple electrical components. This achieves 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 it good compatibility and flexibility. Additionally, the modular design of the components in this application reduces the space occupied by the board-end connector 100 and lowers production costs.

[0040] 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.

[0041] 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.

[0042] In some embodiments, the number of signal terminals 130 is n1, and the number of power terminals 140 is n2, satisfying that n1 < n2, and n1 is not less than an integer of 2. That is, in the board-end connector 100, the number of power terminals 140 n2 is greater than the number of signal terminals 130 n1. This application limits the quantitative relationship between signal terminals 130 and power terminals 140 by limiting the number of power terminals 140 n2 to be greater than the number of signal terminals 130 n1, thereby ensuring that the power supply function of the board-end connector 100 is improved without affecting the signal transmission function of the board-end connector 100, and further improving the overall performance of the board-end connector 100.

[0043] The number of signal terminals 130 (n1) and the number of power terminals 140 (n2) can be directly observed after disassembling the actual board-end connector 100.

[0044] In some embodiments, the number of signal terminals 130 n1 and the number of power terminals 140 n2 further satisfy: n2 / n1 = 2, where n1 is an integer not less than 2. That is, the number of power terminals 140 n2 is twice the number of signal terminals 130 n1, 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.

[0045] For example, in this application, there are two signal terminals 130 and four power terminals 140, but it is not limited to this.

[0046] In some embodiments, refer to Figure 3 The housing 110 includes a first outer wall 112 and a second outer wall 113. The second outer wall 113 is connected to one side of the first outer wall 112 in the first direction X. The first outer wall 112 and the second outer wall 113 together form a receiving cavity 111.

[0047] The first outer wall 112 and the second outer wall 113 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first outer wall 112 can be separately disposed from the second outer wall 113, with a fixed connection between them, for example, the second outer wall 113 can be fixedly connected to the first outer wall 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 outer wall 112 and the second outer wall 113 are integrally injection molded.

[0048] Specifically, a first through hole 1131 is provided on the second outer wall 113, and the shield 120 passes through the first through hole 1131 to achieve the initial positioning of 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.

[0049] In some embodiments, refer to Figure 5 The second outer wall 113 is provided with a first positioning groove 1132, and the shield 120 has a first positioning part 122. The first positioning part 122 is embedded in the first positioning groove 1132, and the two form a positioning and fixing structure. The shield 120 is further positioned and fixed by the cooperation between the first positioning part 122 and the first positioning groove 1132, which further prevents the shield 120 from moving at will, improves the overall structural stability of the board end connector 100, and ensures the normal use of the board end connector 100.

[0050] The first positioning part 122 and the first positioning groove 1132 can be of any shape. For example, in the application, both the first positioning part 122 and the first positioning groove 1132 are polygonal, but are not limited thereto.

[0051] In some embodiments, refer to Figures 1 to 3 The board-end connector 100 also includes a plurality of insulating elements 150, each insulating element 150 being disposed in a corresponding shielding cavity 121, and each insulating element 150 being sleeved on the outer surface of a corresponding signal terminal 130, so as to insulate the signal terminal 130 from the shielding element 120, preventing the signal terminal 130 from contacting the shielding element 120 and causing signal crosstalk, thus ensuring effective and high-speed signal transmission.

[0052] 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.

[0053] 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.

[0054] In some embodiments, refer to Figure 5The shielding component 120 has a second positioning groove 123. Specifically, the second positioning groove 123 is located on the side of the shielding cavity 121 in the third direction Z, and the second positioning groove 123 communicates with the shielding cavity 121. The insulating component 150 has a second positioning part 151, which is embedded in the second positioning groove 123. The two form a positioning and fixing structure, so that the cooperation between the second positioning part 151 and the second positioning groove 123 can further realize the tight assembly between the insulating component 150 and the shielding component 120, further ensuring the overall structural stability of the board-end connector 100, and further ensuring the effective and high-speed transmission of signals in the board-end connector 100.

[0055] The second positioning part 151 and the second positioning groove 123 can be of any shape. For example, in this application, both the second positioning part 151 and the second positioning groove 123 are polygonal, but are not limited thereto.

[0056] In some embodiments, refer to Figure 6 The insulating component 150 has a second through hole 152, and each signal terminal 130 passes through a corresponding second through hole 152 to achieve initial positioning of the signal terminal 130, achieve tight assembly between the insulating component 150 and the signal terminal 130, further ensure the overall structural stability of the board connector 100, and further ensure the effective and high-speed transmission of signals in the board connector 100.

[0057] In some embodiments, refer to Figure 6 The insulating component 150 also has a limiting groove 153.

[0058] Specifically, the signal terminal 130 includes a first main body 131 and a first limiting part 132. The first main body 131 extends along the first direction X, and the first limiting part 132 protrudes from the outer surface of the first main body 131. Each first main body 131 is respectively disposed in a corresponding second through hole 152, and each first limiting part 132 is respectively embedded in a corresponding limiting groove 153. The two together form a limiting and fixing structure, so that the fastening assembly between the insulating member 150 and the signal terminal 130 can be achieved through the cooperation between the first limiting part 132 and the limiting groove 153, 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.

[0059] The first main body portion 131 and the first limiting portion 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first main body portion 131 and the first limiting portion 132 can be separately configured, but fixedly connected, for example, the first limiting portion 132 can be fixedly connected to the first main body 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 main body portion 131 and the first limiting portion 132 are integrally die-cast.

[0060] In some embodiments, refer to Figure 7 Multiple third through holes 1133 are provided on the second outer wall 113.

[0061] Specifically, the power terminal 140 includes a second main body 141 and a second limiting part 142. The second limiting part 142 protrudes from the outer surface of the second main body 141. Each second main body 141 passes through a corresponding third through hole 1133. Each second limiting part 142 is located in a corresponding third through hole 1133. The outer contour dimension of the second limiting part 142 is larger than the inner contour dimension of the third through hole 1133. 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 stable power supply to the power terminal 140 in the board connector 100.

[0062] The second main body 141 and the second limiting part 142 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the second main body 141 and the second limiting part 142 can be separately configured and fixedly connected, for example, the second limiting part 142 can be fixedly connected to the second main body 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 main body 141 and the second limiting part 142 are integrally die-cast.
