[0018] An automotive hole-type connector assembly, as Figure 1 and Figure 2 shown, includes an insulating housing 1, a terminal block 2, a sealing ring 3, an end cover 4, and a positioning hose 16. The terminal block 2 is composed of a connection end 5 for connecting with a terminal post and a welding end 6 for welding with an aluminum wire. A wiring through-hole 7 is provided on the insulating housing 1. The connection end 5 is fixed inside the insulating housing 1, and the connection end 5 coincides with the central axis of the wiring through-hole 7. The welding end 6 is exposed outside the insulating housing 1. The sealing ring 3 is installed at the lower end of the wiring through-hole 7. The end cover 4 is installed at the bottom of the insulating housing 1 in a snap-fit connection manner. The end cover 4 is located below the sealing ring 3 and covers the bottom of the wiring through-hole 7. The positioning hose 16 is used to connect the insulating housing 1 and the end cover 4.
[0019] The insulating housing 1 covers the outside of the connection end 5. On the premise of maintaining the connection function with the terminal post, it provides an external insulation protection function for the terminal 2. The welding end 6 exposed outside the insulating housing 1 can still be welded to the aluminum wire in a conventional manner. The overall joint has the advantage of being lightweight. The sealing ring 3 cooperates with the end cover 4 to provide a waterproof and dustproof function for the area except for the connection area between the insulating housing 1 and the terminal post, providing a safer and more reliable working environment for the terminal 2. In addition, the hose 16 has the advantages of good elasticity and high temperature resistance, being convenient for installation on the insulating housing 1 and the end cover 4, and providing a stable positioning and connection function.

The limiting grooves 8 are symmetrically distributed in the wiring through-hole 7 and are located above the connection end 5. The limiting grooves 8 extend along the axis direction of the wiring through-hole 7. Relying on the limiting grooves 8, the insulating housing 1 can be fixed more safely and stably at the designated position, ensuring that it does not fall off after installation.
[0021] A guiding hole 9 is arranged in the insulating housing 1 in the upper half area of the wiring through-hole 7. The connection end 5 is fixed in the guiding hole 9. The limiting groove 8 is located on the inner wall of the guiding hole 9, and the sealing ring 3 is located below the guiding hole 9, facilitating the installation and positioning of each component on the insulating housing 1.
[0022] The welding end 6 is composed of a welding surface 10 and a crimping wing 11.
[0023] A sealing tube 13 is arranged in the middle of the end cover 4. The sealing tube 13 extends into the wiring through-hole 7, and the outer wall of the sealing tube 13 is closely attached to the inner wall of the sealing ring 3.
