The stop portion 232 is arranged on the inner side of the fitting portion 231, and the stop portion 232 is protruded from the fitting portion 231 toward the support portion 211. By setting the stop portion 232, the inner hole of the support portion 211 is made to be an irregular shape, and then the support portion 211 is inserted into the inner hole of the stop portion 232, thereby improving the torsion resistance between the waterproof component 23 and the support portion 211, avoiding torsional deformation of the waterproof component 23 during the rotation of the nut 22 after the terminal block 21 is engaged with the mounting block 11, thereby improving the waterproof performance of the waterproof component 23.

[0041] Furthermore, the number of the stopper 232 is multiple, and each stopper 232 is evenly spaced along the inner side wall of the sleeve portion 231, so that the torque load between the waterproof member 23 and the wiring seat 21 is evenly distributed, avoiding the local deformation of the waterproof member 23 caused by the concentrated torque load, further improving the waterproof performance of the waterproof member 23, and extending the service life of the waterproof member 23. In this embodiment, the waterproof member 23 also includes a packaging portion 233. The packaging portion 233 is annular and convexly arranged on both sides of the sleeve portion 231. The packaging portion 233 extends along the annular path of the sleeve portion 231, and the packaging portions 233 on both sides are pressed against the support portion 211 and the mounting seat 11 respectively. Specifically, the cross-section of the packaging portion 233 is triangular in shape, and the inner and outer side walls of the annular packaging portion 233 gradually converge from the fitting portion 231 to the direction away from the fitting portion 231. The packaging portion 233 improves the tightness of the waterproof component 23, thereby improving the sealing at the joint between the wiring seat 21 and the mounting seat 11.

[0042] In summary, the embodiment of the utility model provides a two-way installation joint 100, which has the following beneficial effects:

During installation, the first clamping block 13 or the second clamping block 14 can be used as a reference for tightening and fixing, so that the male plug 10 can be installed and fixed on both the inner and outer sides of the housing 90. The installation operation is no longer limited by the internal space of the housing 90, thereby improving the disassembly and assembly efficiency.

[0044] By providing a stopper 232 on the waterproof member 23, the torsional strength at the joint between the waterproof member 23 and the terminal socket 21 is improved, thereby reducing the deformation of the waterproof member 23 during the connection between the male plug 10 and the female plug 20, and improving the sealing performance between the male plug 10 and the female plug 20.

[0045] By setting a packaging portion 233 on the waterproof part 23 and setting the cross-section of the packaging portion 233 to a triangle, the deformation at the position of the packaging portion 233 is increased, thereby improving the tightness of the waterproof part 23 on the terminal block 21 and the mounting block 11, and further improving the sealing performance between the male plug 10 and the female plug 20.
