[0041] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, a connector housing assembly is disclosed. The connector housing assembly mainly includes: a housing 1, a connecting member 3 and a sealing ring 5. The housing 1 includes a flange portion 10 formed with a mounting hole 11. The connecting member 3 passes through the mounting hole 11 on the flange portion 10, and is used to connect the flange portion 10 to the mounting plate 2. The sealing ring 5 is arranged on the flange portion 10, and is used to achieve sealing between the flange portion 10 and the mounting plate 2.

[0043] like Figures 1 to 9 As shown, in the illustrated embodiment, when the flange portion 10 of the housing 1 is connected to the mounting plate 2 by the connecting member 3, the sealing ring 5 is axially squeezed between the flange portion 10 and the mounting plate 2, and the flange portion 10 can move axially and radially relative to the connecting member 3, so that the housing 1 can float axially and radially relative to the mounting plate 2.

[0044] like Figures 1 to 9 As shown, in the illustrated embodiment, the flange portion 10 has a bottom surface 10c facing the mounting plate 2. The sealing ring 5 protrudes from the bottom surface 10c of the flange portion 10 by a predetermined height so as to support the housing 1 on the mounting plate 2 in a floating manner.

[0046] like Figures 1 to 9 As shown, in the illustrated embodiment, when the housing 1 floats axially relative to the mounting plate 2, the sealing ring 5 will elastically deform along the axial direction of the connecting member 3. When the housing 1 floats radially relative to the mounting plate 2, the sealing ring 5 will slide on the top surface of the mounting plate 2 along the radial direction of the connecting member 3, thereby achieving radial floating of the housing 1.

[0047] like Figures 1 to 9 As shown, in the illustrated embodiment, the connecting member 3 mainly includes: a connecting portion 31, an operating portion 34 and a shaft-like portion 33.

[0049] like Figures 1 to 9 As shown, in the illustrated embodiment, the diameter of the flange portion 32 of the connecting member 3 is smaller than the inner diameter of the mounting hole 11 to allow the flange portion 32 to pass through the mounting hole 11. The diameter of the operating portion 34 of the connecting member 3 is larger than the inner diameter of the mounting hole 11 to prevent the operating portion 34 from passing through the mounting hole 11.

[0050] like Figures 1 to 9 As shown, in the illustrated embodiment, the shaft portion 33 of the connecting member 3 extends from the bottom surface of the flange portion 32 to the bottom surface of the operating portion 34, and the axial length of the shaft portion 33 is greater than the thickness of the flange portion 10, so that the flange portion 10 can move axially relative to the connecting member 3.

[0051] like Figures 1 to 9 As shown, in the illustrated embodiment, the connector housing assembly further includes a spring member 6. The spring member 6 is disposed in the gap between the shaft-shaped portion 33 and the mounting hole 11, and is used to position the center line of the mounting hole 11 so that the center line of the mounting hole 11 coincides with the center line of the connector 3. In the illustrated embodiment, when the connector 3 is connected to the nut 4, the connector 3 is fixed, and at this time, the spring member 6 pushes the housing 1 so that the center line of the mounting hole 11 coincides with the center line of the connector 3.

[0052] like Figures 1 to 9 As shown, in the illustrated embodiment, the spring member 6 comprises: a cylindrical body 61 and an elastic portion 62. The cylindrical body 61 is sleeved on the shaft portion 33 and its upper end and lower end respectively abut against the operating portion 34 and the flange portion 32. The elastic portion 62 is connected to the lower end of the cylindrical body 61 and abuts against the inner side of the mounting hole 11.

[0053] like Figures 1 to 9 As shown, in the illustrated embodiment, the elastic portion 62 of the spring member 6 is in the shape of a trumpet that opens upwards. However, the present invention is not limited thereto, and the elastic portion 62 may also have other suitable shapes.

A step 11a is formed on the inner side of the mounting hole 11. The upper end of the elastic portion 62 of the spring member 6 abuts against the supporting surface of the step 11a to ensure that the flange portion 10 is in a horizontal posture perpendicular to the axial direction of the connector 3. In this way, the housing 1 of the connector can be prevented from being deflected during mating.

The cross-sections of the assembly hole 21 of the mounting plate 2 and the one end 41 of the nut 4 are regular polygons to prevent the nut 4 from rotating relative to the mounting plate 2.

[0060] like Figures 1 to 9 As shown, in the illustrated embodiment, a plurality of positioning grooves 10a are formed on the edge of the flange portion 10 of the housing 1. A plurality of positioning protrusions 2a are formed on the mounting plate 2, and the plurality of positioning protrusions 2a respectively cooperate with the plurality of positioning grooves 10a to position the housing 1.

[0061] like Figures 1 to 9 As shown, in the illustrated embodiment, a plug hole 10b is formed on the flange portion 10 of the housing 1, and a pin 2b is formed on the mounting plate 2. The pin 2b is used to cooperate with the plug hole 10b to ensure that the housing 1 is installed on the mounting plate 2 in the correct orientation.
