Abstract
The utility model relates to a double-sided composite shielding case provided with a hole at the junction part of the top end face and the peripheral wall. The double-sided composite shielding case ismainly used for a power distribution system of electrical appliances and has the shielding functions. The double-sided composite shielding case comprises a shielding case body (1), wherein the shielding case body (1) is made of copper and is of an inverted cup-shaped structure; the outer surface and the inner surface of the shielding case body (1) are coated with tin layers (2); and a through hole (3) is arranged at the junction part of the top end face and the peripheral wall of the shielding case (1). In the utility model, through the tin layers which are coated on the outer surface and inner surface of the shielding case body, the oxidation of the copper shielding case body can be avoided so as to greatly prolong the service life of the shielding case.
Description
(1) technical field
The utility model relates to a kind of radome.Be mainly used in the hydroelectric station, nuclear power station electrical equipment distribution system plays the screen effect.
(2) background technology
Before the utility model is made, be used for radome that various electrical equipment distribution systems play the screen effect in the past and rise to stretch by layer of copper mostly and form inverted cup-like structure.Cause oxidation after this radome uses for a long time easily, greatly reduce the useful life of radome like this.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of top end face and two-sided composite shielding cover of periphery wall joint perforate that is difficult for oxidation is provided.
The purpose of this utility model is achieved in that a kind of top end face and the two-sided composite shielding cover of periphery wall joint perforate, comprise the radome body, described radome body is made of copper inverted cup-like structure, outer surface and inner surface at described radome body are coated with the tin layer, have through hole at the top end face and the periphery wall joint of described radome.
The utility model plates the tin layer by outer surface and the inner surface at the radome body, can prevent the oxidation of copper radome body like this, to prolong the useful life of radome greatly.
(4) description of drawings
Fig. 1 is the outside drawing of the utility model top end face and the two-sided composite shielding cover of periphery wall joint perforate.
Fig. 2 is the A-A cut-away view of Fig. 1.
Among the figure: radome body 1, tin layer 2, through hole 3.
(5) embodiment
Referring to Fig. 1, the two-sided composite shielding cover of top end face that the utility model relates to and the perforate of periphery wall joint, comprise radome body 1, described radome body 1 is made of copper inverted cup-like structure, outer surface and inner surface at described radome body 1 are coated with tin layer 2, top end face and periphery wall joint at described radome 1 have through hole 3, so that draw lead.
Claims (1)
1, the two-sided composite shielding cover of a kind of top end face and the perforate of periphery wall joint, comprise radome body (1), described radome body (1) is made of copper inverted cup-like structure, it is characterized in that: outer surface and inner surface at described radome body (1) are coated with tin layer (2), have through hole (3) at the top end face and the periphery wall joint of described radome (1).
