[0025] The front connector connection and fixing mechanism 3 includes a connecting ear 32. The connecting ear 32 is provided on the side of the front connector body 2. A locking block 34 is provided on the side of the connecting ear 32. A fixing hole 33 is provided inside the locking block 34. An ear plate 31 is provided on the side of the T-shaped upper housing 4. A fixing component 35 is provided inside the ear plate 31. A corresponding slot 36 for the locking block 34 is provided on the side of the ear plate 31.

[0026] Specifically, the fixing component 35 includes a circular groove 354. The circular groove 354 is formed inside the side of the ear plate 31. A limiting plate 355 is slidably connected inside the circular groove 354. A fixing rod 356 is provided at the lower end of the limiting plate 355, and a pull rod 353 is provided at the upper end of the limiting plate 355. A spring 351 is sleeved on the surface of the pull rod 353.

[0027] By adopting the above technical solution, the fixing component 35 can make the limiting plate 355 slide in the circular groove 354 through the elastic action of the spring 351, thereby realizing the quick fixing and release of the locking block 34 and ensuring a firm connection between the front connector body 2 and the T-shaped upper housing 4.

[0028] Specifically, the upper end of the pull rod 353 is provided with a pull ring 352, and the two ends of the circular groove 354 are provided with circular holes corresponding to the fixing rod 356 and the pull rod 353.

[0029] By adopting the above technical solution, the design of the pull ring 352 makes it easy for operators to manually pull the pull rod 353 to remove the limit plate 355 from the slot 36, thereby achieving quick disassembly and improving maintenance efficiency.

Finally, the first connecting plate 51 and the second connecting plate 53 are fixedly connected by bolts 52, ensuring a strong connection and sealing performance between the cable connector body 6 and the T-shaped upper housing 4.

[0041] The working principle and usage process of this utility model are as follows: When using this utility model, first insert the front connector body 2 into the front connector slot 8 of the T-shaped upper housing 4, aligning the locking block 34 with the slot 36. Then, by pulling the pull ring 352, the limiting plate 355 is disengaged from the slot 36. After the front connector body 2 is fully inserted, release the pull ring 352. The limiting plate 355 automatically engages with the slot 36 under the action of the spring 351, thus fixing the front connector body 2. The sealing ring 37 automatically... Embedded in the sealing groove 38, ensuring the sealing performance of the front connector; insert the cable connector body 6 into the cable connector slot 7 of the T-shaped upper housing 4, aligning the connecting disc 51 with the connecting disc 53, then embed the sealing ring 543 into the sealing groove 541, ensuring a tight fit between the sealing ring 543 and the connecting discs 51 and 53, and finally fix the connecting discs 51 and 53 with bolts 52, ensuring a firm connection and sealing performance between the cable connector body 6 and the T-shaped upper housing 4.
