AI Technical Summary
Technical Problem
In existing double-gang DC contactors, the connection structure between the wires and the coil results in poor airtightness, and the stacking and wrinkling of the wires affects assembly efficiency and quality.
Method used
A plastic block is used as an adapter fixing base. The adapter conductive parts are welded to the coil pins. The wire ends are placed in the wiring groove and the welding points are completely covered with sealant to form a standardized modular structure.
Benefits of technology
This improves the product's airtightness, prevents wires from piling up and wrinkling, ensures stable assembly quality, and increases assembly efficiency.

Abstract
The wiring sealing structure of a double-gang DC contactor includes a housing, inside which a coil frame and coil pins are provided. A wiring groove runs through the housing wall, and a plastic block is placed inside the wiring groove. A connecting conductive component is fixed on the plastic block. One end of the connecting conductive component is welded to the coil pins, and the other end extends into the wiring groove. The exposed conductor at the end of the wire is placed in the wiring groove and welded to the end of the connecting conductive component located in the wiring groove. The wiring groove is filled with sealant, at least covering the exposed conductor of the wire and its welded joint. This invention, by introducing a plastic block assembly pre-installed with the connecting conductive component, ensures that all exposed wire ends are submerged in the wiring groove and completely covered by sealant, effectively blocking the path of moisture seeping into the wire and significantly improving airtightness. At the same time, the plastic block fixes the position of the welded joint, avoiding the problems of wire stacking and wrinkling during assembly, ensuring assembly quality and efficiency.
