The first insulating member 33 includes an engagement portion 332 embedded in the engagement hole 342 to improve the engagement strength between the first insulating member 33 and the shield cap 34.

[0037] As shown in Figures 1 to 6, in the exemplary embodiment, the engagement hole 342 and the engagement portion 332 are conical in shape, and the diameter of the engagement hole 342 and the engagement portion 332 gradually increases from the inside to the outside of the shield cap 34.

[0038] As shown in Figures 1 to 6, in the exemplary embodiment, the shield cap 34 includes an end wall 34a and a peripheral wall 34b. The peripheral wall 34b is connected around the end wall 34a.

[0048] As shown in Figures 1 to 6, in the exemplary embodiment, the first insulating member 33 is connected between the circumferential insulating portion 322 and the central projection 321 of the second insulating member 32, and therefore the first insulating member 33 cannot be rotated relative to the second insulating member 32. In the exemplary embodiment, a second blind hole 333 suitable for engaging with the central projection 321 of the second insulating member 32 is formed in the first insulating member 33. The cross-sectional shape of the central projection 321 and the second blind hole 333 is five-pointed or other preferred shape.

[0049] As shown in Figures 1 to 6, in the exemplary embodiment, the screw connector 31 engages with the central protrusion 321 of the second insulating member 32, and therefore the screw connector 31 cannot be rotated relative to the second insulating member 32.

[0050] As shown in Figures 1 to 6, in the exemplary embodiment, the screw connector 31 includes a head 311 and a threaded portion 312.

In the exemplary embodiment, the screw connector 31 is a bolt.

[0051] As shown in Figures 1 to 6, in the exemplary embodiment, the connection assembly 30 further includes an insulating cap 36. The insulating cap 36 is fitted over the end 313 of the threaded connector member 31 to prevent contact with the end 313 of the threaded connector member 31 on the side opposite to the head 311.

[0052] As shown in Figures 1 to 6, in the exemplary embodiment, the shield cap 34 of the connection assembly is externally mounted on the mounting port 101 so as to cover the mounting port 101 of the housing 100. The seal ring 35 of the connection assembly, used to seal the gap between the inner wall of the mounting port 101 and the first insulating member 33, is compressed radially between the inner wall of the mounting port 101 and the first insulating member 33.

[0053] As shown in Figures 1 to 6, in the exemplary embodiment, a portion of the mating housing 110 protrudes from the housing 100 for insertion into the mounting hole of the mounting panel.
