Description

Technical Field

[0001] This utility model belongs to the field of wire harness crimp terminals, and relates to a wire harness crimp terminal for mating 1.6×0.6 pins. Background Technology

[0002] Currently, the 0.64mm terminal is the main type used for low-current connectors in the market, primarily for signal transmission, sensors, and low-voltage control circuits. Its small size makes it suitable for space- and weight-sensitive applications. However, the existing 0.64mm terminal has significant limitations in the new energy vehicle scenario: First, insufficient current carrying capacity. Circuits in new energy vehicle auxiliary power supplies and small-to-medium power devices require high current carrying capacity, but the small cross-sectional area and high resistance of the 0.64mm terminal cannot meet these requirements. For example, the 0.64mm terminal will continuously heat up during prolonged operation, with some temperatures reaching as high as 60℃, far exceeding the industry-standard safety threshold of 30-40℃, posing a risk of overheating and fire. Second, weak mechanical strength. New energy vehicles experience continuous vibration during operation, and due to their small size and thin structure, the 0.64mm terminal is prone to loosening or poor contact due to prolonged vibration, affecting circuit stability and even causing functional failures. Third, poor compatibility. With the increase in on-board sensors and control modules, and the increased integration of low-voltage circuits, the current redundancy of the 0.64mm terminal is insufficient, making it difficult to meet the future upgrade requirements of higher-power on-board equipment.

[0003] With the continuous development of new energy vehicles, automotive wiring harnesses have higher current carrying capacity requirements, such as auxiliary power supplies and small and medium power equipment. Therefore, automotive connector female terminals adopt 1.6 terminals. By increasing the cross-sectional area, the current carrying capacity of 1.6 terminals is 2-3 times higher than that of 0.64 terminals, and the mechanical strength is enhanced, which can effectively avoid the above problems and highlight its application necessity.

[0004] However, currently, there is a lack of dedicated crimping terminal structures optimized for the characteristics of 1.6×0.6mm pins (i.e., pins with a width of 1.6mm and a thickness of 0.6mm). Existing terminals are mostly general-purpose designs, which are not well-matched with 1.6×0.6mm pins. After crimping, problems such as insufficient contact area and uneven stress distribution are prone to occur, resulting in the current carrying capacity not being fully utilized. Furthermore, the connection stability under vibration environments is still lacking, and it cannot fully meet the high reliability requirements of new energy vehicles. Utility Model Content

[0011] Furthermore, the terminal is made of a copper alloy.

[0012] Furthermore, when the terminal mates with the wire and the pin, the wire is placed in the wire crimping area, and the terminal crimping pin presses the wire; the pin is inserted into the contact spring and clamped.
