Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, and in particular to an electrical connection terminal and a high-voltage electrical system for a new energy vehicle. Background Art

[0002] As a crucial component of the battery pack, the safety, reliability, and intelligence of the BDU are attracting increasing attention. Traditional BDUs require wiring harnesses to connect various electrical components for control and monitoring. This approach presents challenges such as complex wiring, susceptibility to interference, and difficulty in maintenance.

[0003] The wireless bundled BDU connects control and monitoring signals via a PCB. Compared to traditional wired connections, the wireless bundled BDU offers advantages such as simple wiring, strong anti-interference capabilities, and easy maintenance. Soldering the BDU's electrical components to the PCB is inconvenient for subsequent disassembly and maintenance.

[0004] If the BDU's electrical components are connected to the PCB using terminal blocks, the existing terminal blocks require a lot of force to insert and remove the thicker male terminals of the electrical components, which can easily cause wear on the male terminals. At the same time, the stability of the terminal blocks' clamping needs to be improved. Summary of the Invention

[0005] The embodiment of the present application provides an electrical connection terminal and a high-voltage electrical system for new energy vehicles, which provides additional support for the male end of the electrical component through the cooperation of the support section and the inner wall of the frame, so that the clamping section can maintain a more stable posture when clamping the male end of the electrical component, thereby ensuring the accuracy and reliability of the clamping. At the same time, the clamping section can be in closer contact with the male end of the electrical component, thereby improving the stability and reliability of the electrical connection.

[0006] To achieve the above object, the present invention provides the following technical solutions: an electrical connection terminal, comprising

[0007] The bearing part is in a frame shape and is provided with a hollow inner cavity;

[0008] A connecting portion, the connecting portion being arranged at the lower end of the bearing portion;

[0009] Clamping groups, the clamping groups are multiple pairs, each pair of clamping groups includes two symmetrically arranged elastic arms, in the initial state, there is a gap between the support section and the inner wall of the frame; the two elastic arms are symmetrically extended from the upper part of the frame of the bearing portion toward the inner cavity;

[0010] The elastic arm comprises a connecting section, a transition section, a clamping section for inserting the male end of the electrical component and a supporting section in sequence. The supporting section is located at the end of the elastic arm and tends to lean against the inner wall of the frame of the bearing portion.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] The close contact between the support section and the inner wall of the frame provides additional support for the male terminal of the electrical component, allowing the clamping section to maintain a more stable posture when clamping the male terminal of the electrical component, thereby ensuring the accuracy and reliability of the clamping. At the same time, the clamping section can be in closer contact with the male terminal of the electrical component, thereby improving the stability and reliability of the electrical connection;

[0013] By arranging two elastic arms symmetrically relative to the side wall of the bearing portion in each clamping group and providing a supporting section at the end of each elastic arm, this design greatly enhances the structural stability of the entire terminal block.

[0014] As an improvement, the support section is set in an arc shape. In the initial state, a support distance is set between the end of the support section and the inner wall of the frame. When the male end of the electrical component is inserted into the clamping section, the outer wall of the end of the support section is against the inner wall of the frame, forming a more uniform distribution of support force. This design helps to reduce shaking or displacement caused by uneven support points, thereby improving the stability of the entire structure; the abutment between the ends of the support sections of the two elastic arms and the inner wall of the frame will also generate force feedback respectively. If the male end of the electrical component is inserted off-center, there will be positive feedback on the corresponding side. At the same time, the arc-shaped support section and the support distance between the end of the support section and the inner wall of the frame can keep the male end fixed, reduce friction between the male and female ends, maintain its elasticity and reduce micro-movements caused by vibration.

[0015] As an improvement, the connecting section is tilted toward the side away from the bearing portion. The tilted connecting section design enables the elastic arm to better adapt to changes in the external environment and force when subjected to force, thereby improving its flexibility and adaptability.

[0016] As an improvement, the transition section is connected by an arc to the connecting section and the clamping section. The combined design of the connecting section, the transition section and the clamping section enhances the connection strength between the elastic arm and the bearing part. In particular, the transition section is connected by an arc, which can effectively disperse stress and prevent structural damage caused by stress concentration.

[0017] As an improvement, the electrical connection terminals are plated using a hot-dip plating process. The hot-dip plating process is a process in which a metallurgically bonded alloy coating is formed between the metal substrate and the plating metal through interpenetration, chemical reaction, diffusion, etc. Therefore, there is a good bonding force between the coating and the substrate. Compared with electroplating and chemical plating, the hot-dip plating coating is thicker and its corrosion resistance is also greatly improved.

[0018] A high-voltage electrical system for a new energy vehicle adopts an electrical connection terminal as described above. The electrical system includes a circuit board, and the connecting portion is plugged into the circuit board. The electrical connection terminal is fixedly mounted on the circuit board through the plugging of the connecting portion with the circuit board. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "planar direction", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] like Figures 1 to 3 As shown, an electrical connection terminal includes a bearing part 1, a connecting part 2, and a clamping group. The bearing part 1 is in the shape of a frame and is provided with a hollow inner cavity 1.1. The connecting part 2 is arranged at the lower end of the bearing part 1. There are multiple pairs of clamping groups, and each pair of clamping groups includes two symmetrically arranged elastic arms 3. The two elastic arms 3 are symmetrically extended from the upper part of the frame of the bearing part 1 toward the inner cavity 1.1. The elastic arms 3 sequentially include a connecting section 3.1, a transition section 3.2, a clamping section 3.3 for inserting the male end 4 of the electric component, and a supporting section 3.4. The supporting section 3.4 is placed at the end of the elastic arm 3 and has a tendency to lean against the inner wall of the frame of the bearing part 1.

[0026] The support section 3.4 is arranged in an arc shape. In the initial state, a support distance is provided between the support section 3.4 and the inner wall of the frame. When the male terminal 4 of the electrical component is inserted into the clamping section 3.3, the outer wall of the support section 3.4 abuts against the inner wall of the frame.

[0027] The connecting section 3 . 1 is arranged to be inclined toward the side away from the supporting portion 1 .

[0028] The transition section 3.2 is an arc connecting the connecting section 3.1 and the clamping section 3.3.

[0029] The electrical connection terminals are plated using a hot-dip plating process.

[0030] When the electrical component male terminal 4 is inserted into the clamping section 3.3, the connecting section 3.1, transition section 3.2, and clamping section 3.3 move toward both sides of the cavity, causing the gap between the clamping sections 3.3 to open, allowing the support section 3.4 to move toward both sides of the inner cavity 1.1 along with the clamping section 3.3. After the electrical component male terminal 4 is inserted into the clamping section 3.3, the outer wall of the clamping section 3.3 abuts against the inner wall of the frame, allowing the clamping section 3.3 to more closely contact the electrical component male terminal 4, thereby improving the stability of the clamping while also improving the stability and reliability of the electrical connection. The abutment between the ends of the support sections 3.4 of the two elastic arms and the inner wall of the frame also generates force feedback. If the electrical component male terminal is inserted off-center, the corresponding side will have positive feedback. At the same time, the arc-shaped support section 3.4 and the support spacing between the ends of the support sections 3.4 and the inner wall of the frame can keep the male terminal fixed, reducing friction between the male and female ends, maintaining its elasticity while reducing micro-motion caused by vibration.

[0031] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
