This can effectively improve the service life of the device and reduce the device maintenance cost. And the first main body part 1 of this device does not need to be injection-molded for the second time, making the device production process simple and the manufacturing cost low.

[0042] In summary, the first main body part 1 of the waterproof terminal connector device provided by the present invention does not need to be injection-molded for the second time, making the device production process simple and the manufacturing cost low. And since the terminal posts, the rear end covers 3, and the second main body part 2 of this device are all detachably connected to the first main body part 1, the overall service life of the device can be effectively improved and the device maintenance cost can be reduced.

[0043] On the basis of the above embodiments, preferably, the inner peripheral part of the second main body part 2 is provided with a first internal thread, and the outer peripheral part of the first main body part 1 is provided with a first external thread for cooperating with the first internal thread and a sealing groove 4 for sleeving a sealing ring. The sealing ring is used to seal the gap at the connection between the second main body part 2 and the first main body part 1.

[0044] It should be noted that a wrench position for connecting with a wrench can be set in the middle of the first main body part 1 to facilitate the wrench operation when tightening the first main body part 1 and the second main body part 2 subsequently.

The outer peripheral portion of the first portion is provided with a second spline 8, and the inner peripheral portion of the end of the second main body portion 2 is provided with a keyway 9 for cooperating with the second spline 8, so that the seal 6 is embedded in the end of the second main body portion 2. This can effectively prevent the seal 6 from slipping when the locking member 7 locks the seal 6.

[0058] In the actual application process, the shape, size, material, structure, etc. of the seal 6 and the locking member 7 can be determined according to the actual situation and actual requirements.

[0059] Preferably, an inclined guiding structure is provided inside the end of the locking member 7 that abuts against the sealing member 6 to facilitate the deformation and shrinkage of the sealing member 6. Among them, the locking member 7 can be set as a tightening nut, and a structure for contacting a wrench can be provided on the outer peripheral portion of the tightening nut to facilitate the subsequent tightening of the tightening nut with the wrench, and anti-slip teeth can be provided at this structure to prevent the wrench from slipping when tightening the tightening nut.

[0060] Preferably, a retaining groove 10 is provided at the end of the locking member 7 that contacts the end of the second main body portion 2 to prevent the locking member 7 from loosening after locking the sealing member 6.
