It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the embodiments of this application, reference is made to Figures 1 to 2 This application provides a board-end connector 100, which has a first direction Z, a second direction X, and a third direction Y that intersect each other in pairs. For example, the board-end connector 100 has a first direction Z, a second direction X, 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°.

[0028] Specifically, refer to Figures 1 to 4 The board-end connector 100 includes: a housing 110, a signal terminal 120, and a crimp connector 130.

[0029] Specifically, the housing 110 is provided with a receiving cavity 111; some signal terminals 120 are disposed in the receiving cavity 111; a crimp connector 130 is installed on one side of the housing 110 in the first direction Z, and some signal terminals 120 pass through the crimp connector 130, thereby being soldered to external components to realize the connection between the board connector 100 and external components.

[0030] The housing 110 may be made of plastic, but is not limited to that.

[0031] The signal terminal 120 may be made of any one of copper alloy, tin alloy and brass, but is not limited to this.

[0032] The crimp connector 130 may be made of at least one of polybutylene terephthalate (PBT) or nylon, but is not limited thereto.

[0033] Specifically, refer to Figures 3 to 4The housing 110 has a first outer wall 112 and a second outer wall 113 disposed opposite to each other in the first direction Z. The crimp connector 130 has a third outer wall 1311. The first outer wall 112 and the third outer wall 1311 are disposed on the same side in the first direction Z, and the third outer wall 1311 is disposed close to the second outer wall 113 relative to the first outer wall 112. That is, the first outer wall 112 and the third outer wall 1311 are misaligned in the first direction Z, so that a welding space is formed between the first outer wall 112 and the third outer wall 1311, so that there is sufficient space for welding between the signal terminal 120 and the external components. This greatly reduces the risk of welding failure between the signal terminal 120 and the external components, ensures the welding effect between the signal terminal 120 and the external components, and improves the assembly efficiency between the board connector 100 and the external components.

[0034] In some embodiments, refer to Figures 5 to 6 The distance between the first outer wall 112 and the third outer wall 1311 is H mm, satisfying: 0.5 ≤ H ≤ 0.7. That is, the distance H mm between the first outer wall 112 and the third outer wall 1311 can be controlled within the range of 0.5 mm to 0.7 mm. For example, H mm can be one or any combination of 0.5 mm, 0.52 mm, 0.54 mm, 0.56 mm, 0.58 mm, 0.6 mm, 0.62 mm, 0.64 mm, 0.66 mm, 0.68 mm, or 0.7 mm. The specific values ​​of H mm given above are only illustrative examples, and any value within the range of 0.5 mm to 0.7 mm is within the protection scope of this application. This application limits the distance H mm between the first outer wall 112 and the third outer wall 1311 to within the range of 0.5 mm to 0.7 mm to rationally design the structural dimensions of the board-end connector 100, thereby providing sufficient space for soldering between the signal terminal 120 and external components. This greatly reduces the risk of soldering failure between the signal terminal 120 and external components, ensures the soldering effect between the signal terminal 120 and external components, and improves the assembly efficiency between the board-end connector 100 and external components.

[0035] The distance H mm between the first outer wall 112 and the third outer wall 1311 can be obtained by measuring the distances in the first direction Z of the actual board-end connector 100 housing 110 and the third outer wall 1311 of the crimp connector 130 multiple times using a measuring tool and calculating the average value. The measuring tool can be any one of a ruler, vernier caliper, or other dimensional measuring instruments, but is not limited to this.

[0036] In a preferred embodiment of this application, the distance H mm between the first outer wall 112 and the third outer wall 1311 is 6 mm.

[0037] In some embodiments, refer to Figures 2 to 4 A connecting groove 114 is provided on the side of the housing 110 near the first outer wall 112.

[0038] The connecting groove 114 can be of any shape. For example, in this application, the connecting groove 114 is a polygonal groove.

[0039] Specifically, the crimp connector 130 includes a crimping portion 131 and a connecting portion 132. The crimping portion 131 is disposed on one side of the housing 110 in the first direction Z, and a portion of the signal terminals 120 pass through the crimping portion 131. The connecting portion 132 is connected to the side of the crimping portion 131 near the housing 110. At least a portion of the connecting portion 132 is embedded in the connecting groove 114 to achieve a connection and fixation between the crimp connector 130 and the housing 110, prevent the crimp connector 130 from moving freely, and help improve the overall structural stability of the board end connector 100.

[0040] The crimping portion 131 and the connecting portion 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the crimping portion 131 and the connecting portion 132 can be separate components, fixedly connected together, for example, by means of snap-fit, adhesive bonding, or riveting. This application does not impose specific limitations; the configuration can be tailored to the actual situation.

[0041] In some embodiments, refer to Figures 2 to 4 Multiple connecting grooves 114 are provided, each connecting groove 114 is respectively provided on both sides of the housing 110 in the second direction X; multiple connecting parts 132 are provided, each connecting part 132 is respectively provided on both sides of the crimping part 131 in the second direction X, and each connecting part 132 is respectively embedded in a corresponding connecting groove 114, that is, multiple connecting parts 132 on the crimping connector 130 are respectively embedded in multiple connecting grooves 114 on the housing 110, so as to further ensure the connection and fixing effect between the crimping connector 130 and the housing 110, ensure the connection tightness between the crimping connector 130 and the housing 110, and further help to improve the overall structural stability of the board end connector 100.

[0042] In some embodiments, refer to Figures 2 to 4 Multiple signal terminals 120 are provided, and the multiple signal terminals 120 are arranged at intervals in the second direction X.

[0043] Specifically, the crimp connector 130 further includes: multiple partitions 133, each partition 133 being connected to the side of the crimp connector 131 near the housing 110, and each partition 133 being disposed between two adjacent signal terminals 120 to shield and separate the two adjacent signal terminals 120, preventing crosstalk between different signal terminals 120, thereby maintaining signal integrity and stability, while protecting the signal terminals 120 from mechanical, electromagnetic or environmental damage, effectively guiding and dispersing the charge or current on the signal terminals 120, thereby reducing voltage fluctuations in the signal line and improving the anti-interference capability and signal stability of the board connector 100.

[0044] The crimping portion 131 and the partition portion 133 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the crimping portion 131 and the partition portion 133 can be separate components, fixedly connected together, for example, by means of snap-fit, adhesive bonding, or riveting. This application does not impose specific limitations; the configuration can be tailored to the actual situation.

[0045] In some embodiments, refer to Figure 2 The signal terminal 120 includes a first signal part 121 and a second signal part 122 that are connected to each other. The first signal part 121 extends along a third direction Y, and the second signal part 122 extends along a first direction Z. The first signal part 121 and the second signal part 122 are designed at an angle to each other. For example, in this application, the first signal part 121 and the second signal part 122 are designed to be perpendicular to each other.

[0046] Specifically, each partition 133 is disposed between two adjacent second signal sections 122.

[0047] In some embodiments, different signal terminals 120 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.

[0048] In some embodiments, refer to Figures 2 to 4 The crimping part 131 has multiple through holes 1312, and a portion of each signal terminal 120 passes through a corresponding through hole 1312.

[0049] The through hole 1312 can be of any shape. For example, in this application, the through hole 1312 is a polygon and is adapted to the shape of the signal terminal 120.

[0050] In some embodiments, refer to Figure 4 , Figures 7 to 8The crimping portion 131 is also provided with at least three heat dissipation holes 1313. Each heat dissipation hole 1313 penetrates the crimping portion 131 in the first direction Z, and the heat dissipation holes 1313 are arranged at intervals in the second direction X and the third direction Y, which helps to ensure the ventilation and heat dissipation effect in the welding space formed between the first outer wall 112 and the third outer wall 1311, thereby further reducing the risk of welding failure between the signal terminal 120 and external components, ensuring the welding effect between the signal terminal 120 and external components, and improving the assembly efficiency between the board connector 100 and external components.

[0051] The heat dissipation hole 1313 can be of any shape. For example, in this application, the through hole 1312 is a polygon, but it is not limited to this.

[0052] In a preferred embodiment of this application, 16 heat dissipation holes 1313 are provided, and the 16 heat dissipation holes 1313 are arranged at intervals in the second direction X and the third direction Y.

[0053] In some embodiments, refer to Figure 4 The crimping connector 130 also includes a plurality of support bosses 134, each support boss 134 extending along the first direction Z, and each support boss 134 protruding from the third outer wall 1311.

[0054] The pressing part 131 and the supporting boss 134 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the pressing part 131 and the supporting boss 134 can be separate components, fixedly connected together, for example, by means of snap-fit, adhesive bonding, or riveting. This application does not impose specific limitations; the configuration can be tailored to the actual situation.

[0055] Understandably, this application provides a support boss 134 so that when the board-end connector 100 is connected and assembled with external components, the support boss 134 can abut against the external components to support the board-end connector 100. This helps to keep the welding space formed between the first outer wall 112 and the third outer wall 1311 unchanged, so that there is sufficient space for welding between the signal terminal 120 and the external components. This greatly reduces the risk of welding failure between the signal terminal 120 and the external components, ensures the welding effect between the signal terminal 120 and the external components, and improves the assembly efficiency between the board-end connector 100 and the external components.

[0056] In some embodiments, the dimension of the support boss 134 in the first direction Z is not greater than the distance H mm between the first outer wall 112 and the third outer wall 1311.

[0057] In some embodiments, refer to Figure 2The board-end connector also includes a shielding unit 140, which is used to shield the signal terminal 120.

[0058] Specifically, the shielding unit 140 includes: a first shielding element 141 and a second shielding element 142. Multiple first shielding elements 141 are provided and arranged at intervals in the second direction X. The second shielding elements 142 are respectively connected to each of the first shielding elements 141. The first shielding elements 141 and the second shielding elements 142 cooperate to form multiple shielding spaces 143. Each signal terminal 120 is respectively disposed in a corresponding shielding space 143. The first shielding elements 141 and the second shielding elements 142 are used to shield the signal terminals, ensuring that the shielding unit 140 effectively shields the signal terminals 120 from external electromagnetic interference, preventing crosstalk between different signal terminals 120, maintaining signal integrity and stability, and protecting the signal terminals 120 from mechanical, electromagnetic, or environmental damage. It also effectively guides and disperses the charge or current on the signal terminals 120, thereby reducing voltage fluctuations in the signal lines and improving the anti-interference capability and signal stability of the board connector 100.

[0059] The first shielding member 141 and the second shielding member 142 are made of metal. For example, the first shielding member 141 and the second shielding member 142 are made of zinc alloy, but are not limited thereto.

[0060] In some embodiments, the shielding unit 140 includes a third shielding member 144, which is connected to the first shielding member 141 on the Y-direction side, to further ensure that the shielding unit 140 effectively shields the signal terminal 120 from external electromagnetic waves, prevents crosstalk between different signal terminals 120, and maintains the integrity and stability of the signal.

[0061] The third shielding element 144 is made of metal, for example, a zinc alloy, but is not limited thereto.

[0062] On the other hand, in the embodiments of this application, this application also provides a vehicle, including: a board-end connector 100 as described in any of the above embodiments, the board-end connector 100 being used to realize electrical connection between different electrical components in the vehicle, so as to realize signal transmission between different electrical components.
