[0053] Please refer to Figures 1 to 6As shown, a shielding cage assembly disclosed in the present application is generally used to cooperate with one or more connector modules (not shown) to form a complete electrical connector, and the connector can be installed in devices such as base stations. Specifically, the shielding cage assembly includes a cage body 1 and a water cooling module 2 cooperating with the cage body 1. The cage body 1 includes: a top plate member 14, two side plate members 15 respectively extending downward from the left and right sides of the top plate member 14, a bottom plate member 16 arranged opposite to and spaced from the top plate member 14 in the up and down direction, and a rear end plate 17 fixed to the rear end edges of the top plate member 14 and the two side plate members 15. The bottom plate member 16 is fixed to the lower end edges of the two side plate members 15.

[0054] Wherein, a rectangular slot 150 opening forward is formed at the front end position of each side plate member 15. The cage body 1 further includes a first partition plate 11, a second partition plate 12 and a third partition plate 13. The left and right side edges of the first partition plate 11 are respectively fixed to the upper edges of the slots 150 of the two side plate members 15. The left and right side edges of the second partition plate 12 are respectively fixed to the lower edges of the slots 150 of the two side plate members 15. The left and right side edges of the third partition plate 13 are respectively fixed to the rear edges of the slots 150 of the two side plate members 15. A second accommodation cavity 102 is formed between the top plate member 14 and the first partition plate 11. A third accommodation cavity 103 is formed between the bottom plate member 16 and the second partition plate 12. An installation cavity 104 is formed between the first partition plate 11 and the second partition plate 12. The first accommodation cavity 101 is defined and formed at the rear end position of the cage body 1 by the top plate member 14, the two side plate members 15, the rear end plate 17 and the third partition plate 13.

The middle position of the second partition plate 12 in the left-right direction is fixed to the lower edge of the slot 150 of the spacer plate 18. The middle position of the third partition plate 13 in the left-right direction is fixed to the rear edge of the slot 150 of the spacer plate 18.

[0059] Further, in order to achieve a better shielding effect, the present application preferably provides that: there are no through-hole structures on the part of the first partition plate 11 that separates the second accommodation cavity 102 and the installation cavity 104 in the up-and-down direction; and / or there are no through-hole structures on the part of the second partition plate 12 that separates the second accommodation cavity 102 and the installation cavity 104 in the up-and-down direction.
