Terminal blocks or terminals are often used to connect the power terminals. Considering that the space in the vehicle must be fully utilized, the reliability and safety of high-voltage and high-current conduction on the terminal blocks or terminals must be guaranteed. Therefore, a terminal with a reasonable structural design will help to make better use of the space in the vehicle while ensuring the reliability and safety of high-voltage and high-current conduction. Utility Model Content

[0016] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0017] like Figure 1-Figure 4 As shown, an inverter terminal for a new energy electric vehicle comprises a cylindrical main body 1 with a wide, flat cylindrical head 2 disposed on its upper portion. The main body 1 and head 2 are coaxial, and the outer diameter of the main body 1 is smaller than that of the head 2. An axial notch 3 is formed at the lower portion of the main body 1 by truncating a portion of the longitudinal section along the axial direction. The height ratio h2:h1 of the portion of the main body 1 with the axial notch 3 to the portion without the notch is 2:1. The width ratio of the axial notch 3 to the maximum width d2 of the rectangular cross section to the remaining portion to the maximum width d1 of the rectangular cross section is d2:d1 = 1:2. A wire inlet hole 4 extending toward the main body 1 is defined in the center of the head 2. The inner wall of the wire inlet hole 4 is internally threaded and has an inverted tapered portion at its lowermost portion. Three wire outlet holes 5 extending radially through the main body 1 are disposed on the rectangular end surface of the axial notch 3 of the main body 1. These three wire outlet holes 5 are evenly spaced along the axial direction of the main body 1.

[0018] The inverter terminal for new energy electric vehicles designed in this utility model is an integrated structure with an overall pin-like structure. It is used to connect the incoming wire and multiple outgoing wires to achieve a stable connection between the incoming wires and the outgoing wires. When in use, the main body 1 is passed through the mounting sleeve that fixes the entire terminal in the vehicle. The step formed between the head 2 and the main body 1 is used to clamp the terminal on the mounting hole. Then, the fixing screw and the annular copper nose of the outgoing wire are inserted into the topmost outgoing wire connection hole 5. After tightening the fixing screw, the outgoing wire is fixed to the rectangular contact surface of the axial notch 3 at the outgoing wire connection hole 5. The same method is used to connect other outgoing wires. In this way, the step formed between the head 2 and the main body 1 and the fixing screw of the topmost outgoing wire connection hole 5 can fix the entire terminal to the terminal mounting sleeve on the vehicle. After determining the outgoing line's path and securing the terminal, the incoming line's annular copper nose is mounted on the upper end face of the head 2 using a fixing screw. This allows the incoming and outgoing lines connected to the terminal of the present invention to run in different planes, making wiring more flexible and effectively utilizing irregular spaces within the vehicle. This structural design also facilitates wiring operations. The incoming and outgoing lines have separate mounting locations, both with surface contact, ensuring safe and reliable electrical conductivity, meeting the requirements for high-voltage and high-current applications.

[0019] The above embodiments are only preferred implementation methods of the present invention and are only used to explain the present invention rather than to limit the present invention. Any changes, replacements, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principles of the present invention shall be considered as equivalent replacement methods and shall be included in the scope of protection of the present invention.
