AI Technical Summary
The connection reliability of the mating terminals in the existing wire harness is poor, and problems such as oxidation, corrosion and structural loosening are prone to occur.
The design employs bare wire soldering to the mating terminals, combined with a flexible inner core and a rigid outer shell. The bare wire and the mating terminal form the first sealing zone. The flexible inner core is then injection molded, and the rigid outer shell provides a second layer of sealing to prevent oxidation and structural deformation.
It improves the reliability and sealing of the connection, prevents oxidation and corrosion, absorbs mechanical stress, avoids fatigue fracture of the weld, and enhances resistance to extrusion and friction.

Abstract
Claims
1. A wire harness with mating terminals, comprising a terminal mounting component, mating terminals, and a cable, wherein there are multiple mating terminals mounted within the terminal mounting component, and the cable comprises multiple core wires, each core wire having a bare end near the mating terminal, characterized in that: Each of the bare wires of the core wires is soldered one-to-one to the multiple mating terminals; Along the length of the wire harness, the bare wire and the position of the bare wire and the corresponding mating terminal form the first sealing area, and the two ends of the terminal mounting piece and the cable that are close to each other and the area between them form the second sealing area. It also includes an elastic inner core and a rigid outer shell, both of which are formed by injection molding. The elastic inner core is sealed and wrapped in the first sealing area, and the rigid outer shell is sealed and wrapped in the second sealing area.
2. The wire harness with terminal docking of claim 1, wherein: The terminal mounting component has multiple mounting cavities; Each mating terminal is installed inside the mounting cavity, and its outer side wall is sealed against the inner side wall of the corresponding mounting cavity.
3. The wire harness with terminalized ends of claim 2, wherein: The mating terminal is a female terminal, and a limiting piece is provided inside the female terminal. The limiting piece is used to limit and cooperate with the male terminal. The limiting piece is sealed and cooperated with the inner wall of the mating terminal, thereby dividing the inner cavity of the mating terminal into two independent cavities located on both sides of the limiting piece. One end of the first sealing area extends to the limiting piece.
4. The wire harness with terminalized ends of claim 3, wherein: The terminal mounting component is equipped with a sealing ring.
5. The wire harness with terminalized ends of claim 3, wherein: The terminal mounting component is fitted with a nut sleeve.
6. The wire harness with terminalized ends of claim 1, wherein: The outer wall of the terminal mounting component is provided with a limiting groove, which is matched with the rigid outer shell for limiting.
7. The wire harness with mating terminals according to claim 1, characterized in that: The outer wall of the rigid shell has multiple grooves.
8. The wire harness with terminalized ends of claim 1, wherein: The outer side wall of the rigid housing has a protrusion at the end away from the wire harness.
9. The wire harness with terminalized ends of claim 1, wherein: The terminal mounting component has multiple support blocks near the end of the cable, and the multiple support blocks are arranged in a rotating array, with at least some of the support blocks having positioning grooves.
10. The wire harness with terminalized ends of claim 1, wherein: The terminal mounting component has indicator markings on both end faces.
