[0032] As shown in Figures 1 to 3, in the illustrated embodiment, a sealing member is provided at the mating interface to seal these mating interfaces. In one embodiment of the present invention, the sealing member may be a sealing strip, a sealing block, a sealing ring, or a sealant.

[0033] Figure 4 is an assembly diagram of the elastic seal block 40 and electrical connection members 1, 2, and 3 shown in Figure 3.

[0034] As shown in Figures 1 to 4, in the illustrated embodiment, an elastic seal block 40 is placed on the seal cover 30 to seal the mating interface between the seal cover 30 and the electrical connection members 1, 2, and 3.

The electrical connection members 1, 2, and 3 pass through the through holes 41 and 42 of the elastic seal block 40 and are hermetically fitted with the elastic seal block 40.

[0036] As shown in Figures 1 to 4, in the illustrated embodiment, a first elastic seal ring S1 is positioned between the mating surfaces of the shield connecting member 20 and the housing 10, and the first elastic seal ring S1 is compressed between the shield connecting member 20 and the housing 10 along the axial direction of the housing 10 to seal the mating interface between the shield connecting member 20 and the housing 10.

[0045] The main difference between the connector housing assemblies shown in Figures 5 and 6 and those shown in Figures 1 to 4 lies in the different sealing methods used at several mating interfaces.

[0046] As shown in Figures 5 and 6, in the illustrated embodiment, the axis of the housing 10 is inclined at a predetermined angle with respect to the axis of the seal cover 30. In this way, the mating connector housing assembly of the mating connector can be inserted into the housing 10 of the connector housing assembly at a predetermined angle.

[0047] As shown in Figures 5 and 6, in the illustrated embodiment, the mating interface between the seal cover 30 and the shield connecting member 20, the mating interface between the seal cover 30 and the electrical connecting members 1, 2, and 3, and the mating interface between the shield connecting member 20 and the housing 10 are sealed with sealant G.

[0048] As shown in Figures 5 and 6, in the illustrated embodiment, the seal cover 30 includes a peripheral wall and a bottom wall, and the through holes 31, 32, and 33 are formed in the bottom wall of the seal cover 30. The mating surfaces of the electrical connection members 1, 2, and 3 and the through holes 31, 32, and 33 are coated with sealant G to seal the mating interface between the electrical connection members 1, 2, and 3 and the through holes 31, 32, and 33 of the seal cover 30.

[0049] As shown in Figures 5 and 6, in the illustrated embodiment, sealant G is applied to the mating surface between the shield connecting member 20 and the housing 10 to seal the mating interface between the shield connecting member 20 and the housing 10.

[0050] As shown in Figures 5 and 6, in the illustrated embodiment, sealant G is applied to the mating surface between the seal cover 30 and the shield connecting member 20 to seal the mating interface between the seal cover 30 and the shield connecting member 20.

[0051] As shown in Figures 5 and 6, in the illustrated embodiment, an elastic seal ring S is positioned on the bottom surface of the shielding connector 20 that contacts the shell 100 of the electrical equipment. The elastic seal ring S is compressed between the shielding connector 20 and the shell 100 of the electrical equipment along the axial direction of the seal cover 30 to seal the mating interface between the shielding connector 20 and the shell 100 of the electrical equipment.

[0052] In addition to the differences mentioned above, other technical features of the connector housing assemblies shown in Figures 5 and 6 can be found by referring to the connector housing assemblies shown in Figures 1 to 4, which will not be repeated here, but are essentially the same as those shown in Figures 1 to 4.

[0053] In another exemplary embodiment of the present invention, a connector is also disclosed. This connector comprises a connector housing assembly and electrical connection members 1, 2, and 3. The electrical connection members 1, 2, and 3 are attached to the connector housing assembly and extend from a seal cover 30. In the illustrated embodiment, the electrical connection members 1, 2, and 3 may include a power connection terminal 1, a signal connection terminal 2, or a connection wire 3.

[0054] As shown in Figures 1 to 6, in the illustrated embodiment, the connector may also include a plurality of sealing members S, S1, S2, S3, 40, and G. The plurality of sealing members are used to seal the mating interface between the housing 10 and the shielding connection member 20, the mating interface between the shielding connection member 20 and the seal cover 30, and the mating interface between the seal cover 30 and the electrical connection members 1, 2, and 3, respectively. Thus, in the illustrated embodiment, the connector is sealed at the installation opening of the housing 10.
