This invention relates to the field of automotive connector technology, specifically to an interlocking connector with a fixed position. It includes a fixed wiring portion mounted on a circuit board, with a height space formed between the fixed wiring portion and the circuit board. Three connector sleeves are mounted on the fixed wiring portion. A power terminal and two signal terminals are located within the left connector sleeve, and wiring portions are located on the power and signal terminals. By using female end sleeves, this invention can enclose the power and signal wiring portions, with both the signal and power terminals inserted into the connector sleeves. This achieves multi-layer isolation, improving sealing stability. Furthermore, the internal space can provide insulation, reducing direct interference from temperature differences to the internal environment and minimizing gap formation.
