[0075] Identical or functionally equivalent elements are provided with the same reference numerals in all figures.

[0076] Fig. 1 shows a schematic sectional view of a shielding element, designated as a whole by 100, for electromagnetic shielding of an electronic component not shown in detail according to a first embodiment according to the disclosure.

[0079] The shielding element 100 comprises a base body 102 and an electrically conductive layer 104 provided on the base body 102.

[0080] The base body 102 is formed as an injection-molded part made of a plastic material, for example a thermoplastic or a fiber-reinforced plastic.

[0081] The base body 102 can be formed by a conventional injection molding process as well as by a foam injection molding process, an injection compression molding process and / or a pressing process.

[0082] The base body 102 can have any geometric configuration, for example, the base body 102 can have a substantially rectangular, round, oval or similar basic shape in a plan view.

[0083] In particular, the base body 102 has a substantially planar basic shape.

[0084] The base body 102 is essentially formed by a wall section 106 and an edge section 108 adjoining the wall section 106.

[0088] The wall section 106 may, for example, have a wall thickness of about 2 mm to about 8 mm.

[0089] The electrically conductive layer 104 is attached to a surface of the base body 102.

[0090] In particular, the electrically conductive layer 104 is provided over the entire surface of the base body 102.

[0092] According to Fig. 1, the electrically conductive layer 104 is arranged on an inner side 110 of the shielding element 100. In the illustration according to Fig. 1, the inner side 110 of the shielding element 100 forms an upper side or a side of the shielding element 100 facing an interior space.

[0093] In other words, when the shielding element 100 is coupled to the corresponding device, the electrically conductive layer 104 provided on the inner side 110 of the shielding element 100 faces the interior space in which the electronic component to be electromagnetically shielded is arranged.

[0094] The electrically conductive layer 104 and the base body 102 are joined together in particular by the injection molding process, the injection compression molding process and / or the pressing process.

[0095] In order to permanently connect the base body 102 and the electrically conductive layer 104, an adhesion promoter 112 is preferably provided between them.

[0096] Such an adhesion promoter 112 increases the chemical and / or physical connection between the base body 102 and the electrically conductive layer 104 and is also referred to as a primer.

[0097] The electrically conductive layer 104 can be formed in various ways, as will be described below.

[0098] Preferably, the electrically conductive layer 104 may be formed from a metallic material, in particular from a metallic material or a metallic alloy.

[0099] For example, the electrically conductive layer 104 may be formed of aluminum, copper, iron, nickel, silver or the like.

[0100] Alternatively, the electrically conductive layer 104 may consist of an electrically conductive organic material, in particular of carbon, preferably carbon fibers, graphite or the like.

[0101] It can also be provided that the electrically conductive layer 104 is formed from a combination of one of the aforementioned electrically conductive materials and an electrically non-conductive material.

[0102] For example, an electrically non-conductive material may be provided with or coated with an electrically conductive material, in particular a metallic material or an electrically conductive organic material.

[0103] For example, the electrically conductive layer 104 can be formed from any knitted fabric. For example, the electrically conductive layer 104 can be formed from a woven fabric, a scrim, a knitted fabric, a warp-knitted fabric, a nonwoven fabric, or the like, which is provided with or coated with a corresponding electrically conductive material.

[0104] The woven fabric, scrim, knitted fabric, warp-knitted fabric, nonwoven fabric or the like can be formed from an electrically conductive material, in particular a metallic material, electrically conductive organic material or the like, as well as from an electrically non-conductive material, for example from a fiber material, preferably from a plastic, which is provided with or coated with an electrically conductive material.

[0105] Advantageously, the electrically conductive layer 104 can also be formed as a foil, as a sheet, as a perforated sheet, as an expanded metal, as an expanded grid or the like made of one of the aforementioned electrically conductive materials.

[0106] The foil, sheet, perforated sheet, expanded metal, expanded grid or the like is formed in particular from a metallic material, for example from aluminum, copper, iron, nickel, silver or the like, or from an electrically conductive organic material, in particular from carbon, preferably carbon fibers, graphite or the like.

[0107] A coupling device 114 is provided on the edge section 108, by means of which the shielding element 100 can be attached, in particular detachably attached, to a correspondingly designed coupling device of the corresponding device.

[0108] For example, the coupling device 114 is designed as a flange-like connecting section.

[0109] In particular, the coupling device 114 has a plurality of passages 116, each of which extends through the edge portion 108 of the base body 102.

[0110] In particular, the plurality of passages 116 are arranged spaced apart from one another along the edge portion 108.

[0111] The passages 116 are designed such that a fastening means 118, in particular a screw, can be inserted into each of them in order to fasten, in particular screw, the shielding element 100 to the corresponding device.

[0112] An outer sealing element 120 can be provided on the base body 102, which seals the passage 116 with the fastening means 118 inserted therein to an outer side 122 of the base body 102.

[0113] In particular, the outer sealing element 120 is arranged between a screw head of the fastening means 118 designed as a screw.

[0114] In particular, the outer sealing element 120 is designed as an annular seal, for example an O-ring, which is arranged surrounding the passage 116.

[0115] The outer sealing element 120 can be received in a groove formed on the base body 102.

[0116] An electrically conductive, sleeve-shaped element 124 is provided in each of the multiple passages 116. This sleeve-shaped element 124 is inserted into the passage 116, for example, overmolded by the base body or introduced, molded, or pressed into the passage 116 of the base body 102.

[0117] Preferably, the sleeve-shaped element 124 is formed from a metallic material, carbon, graphite or the like.

[0118] The sleeve-shaped element 124 preferably extends completely through the passage 116.

[0119] The sleeve-shaped element 124 has a circular through-section so that the fastening means 118, in particular the screw, can be inserted into it.

[0120] An internal thread for screwing in the fastening means 118 can be formed in the sleeve-shaped element 124.

[0121] An electrical contact is preferably formed between the sleeve-shaped element 124 and the fastening means 118.

[0122] Towards the inner side 110 of the shielding element 100, the sleeve-shaped element 124 forms an electrically conductive contact section 126

[0123] In particular, the electrically conductive contact section 126 is formed by an end face of the sleeve-shaped element 124.

[0124] The end face of the sleeve-shaped element 124 on the inner side 110 can be either flush with the base body 102 or protrude from a surface on the inner side 100.

[0125] The electrically conductive contact section 126 is designed to form an electrical contact with the corresponding device when the shielding element 100 is coupled thereto.

[0126] The electrically conductive layer 104 can be formed on the inner side 110 of the base body 102 in such a way that the electrically conductive contact section 126 is formed both by the end face of the sleeve-shaped element 124 and by the electrically conductive layer 104.

[0127] For example, the electrically conductive layer 104 can be formed on the inner side 110 of the base body 100 in such a way that it surrounds the passage 116 or the sleeve-shaped element 124, ie the end face of the sleeve-shaped element 124.

[0128] Likewise, the electrically conductive layer 104 can be formed in such a way that it at least partially covers the end face of the sleeve-shaped element 124 on the inner side 110 of the base body 100.

[0129] As a result, it can preferably be provided that the electrically conductive contact section 126 is formed only by the electrically conductive layer 104 or is formed jointly by the electrically conductive layer 104 and the end face of the sleeve-shaped element 124.

[0130] An inner sealing element 128 is provided on the inner side 110 of the base body 102.

[0131] This inner sealing element 128 is arranged on an outer side on the edge portion 108 of the base body 102 in order to form a seal towards the outer side 122 when the shielding element 100 is coupled to the corresponding device.

[0132] The inner sealing element 128 can be designed either as a seal made of an elastomeric material, for example a plastic, rubber or the like, or as a liquid seal.

[0133] In Fig. 2 shows a schematic sectional view of the shielding element 100 according to a second embodiment of the disclosure.

[0134] The following will exclusively address differences between this second embodiment of the shielding element 100 and the previously described first embodiment of the shielding element 100. Equivalent configurations will not be explained repeatedly and may, in particular, correspond to the first embodiment of the shielding element 100.

[0135] In this second embodiment of the shielding element 100, an electrically conductive projection 130 is formed on the inner side 110 of the base body 102.

[0136] This electrically conductive projection 130 is provided to form an electrical contact between the electrically conductive layer 104 and the corresponding device when coupling the shielding element 100.

[0137] The projection 130 is formed by the base body 102 and is formed in particular by the injection molding process, the injection-compression molding process, and / or the pressing process. However, it can also be attached to the base body 102 after the injection molding process, the injection-compression molding process, and / or the pressing process.

[0138] Preferably, the projection 130 is provided on a side of the coupling device 114 opposite the outer edge portion 108.

[0139] In other words, the projection 130 is arranged between the coupling device 114 and the wall portion 106 of the base body 102.

[0140] Preferably, the projection 130 is formed as a fold extending at least partially along the edge portion 108 of the base body 102.

[0141] In particular, the projection 130 extends completely along the edge portion 108 of the base body 102.

[0142] To form the electrical conductivity of the projection 130, it is covered with the electrically conductive layer 104 provided on the inner side 110.

[0143] By the projection 130 protruding with respect to the inner side 110 relative to the base body 102, the electrical contact can be formed when coupling the shielding element 100 with the corresponding device by pressing the projection 130 against the corresponding device in an electrically contacted manner during the coupling.

[0144] In addition, in this second embodiment of the shielding element 100, it is provided that the electrically conductive layer 104 does not extend to the electrically conductive, sleeve-shaped element 124 and is not electrically contacted therewith.

[0145] The inner sealing element 128 is arranged between the electrically conductive element 124 and the electrically conductive layer 104 in order to form a seal with the outside 122.

[0146] The inner sealing element 128 is arranged in a groove formed in the base body 102, which is preferably provided adjacent to the electrically conductive element 124.

[0147] In this embodiment, the inner sealing element 128 is particularly designed such that it runs correspondingly to the projection 130 extending at least partially along the edge portion 108 of the base body 102.

[0148] In particular, the inner sealing element 128 extends corresponding to the projection 130 over its entire circumference, for example as a ring seal, along the edge portion 108 of the base body 102.

[0149] The inner sealing element 128 is in particular formed from an elastomeric material, for example from a plastic, rubber or the like.

[0150] Fig. 3 shows a schematic sectional view of the shielding element 100 according to a third embodiment of the disclosure, which represents a modification of the second embodiment.

[0151] In this third embodiment of the shielding element 100, instead of the sealing element 128 made of the elastomeric material accommodated in the groove, this is designed as a liquid seal.

[0152] This sealing element 128, designed as a liquid seal, is applied to the inside 110 of a surface of the base body 102.

[0153] In particular, the sealing element 128 designed as a liquid seal is provided between the projection 130 and the coupling device 114.

[0154] Preferably, in this embodiment, it is also provided that the sealing element 128 designed as a liquid seal runs correspondingly to the projection 130 extending at least partially along the edge portion 108 of the base body 102.

[0155] In particular, the sealing element 128 designed as a liquid seal extends corresponding to the projection 130 completely along the edge section 108 of the base body 102.

[0156] Fig. 4 shows a schematic sectional view of the shielding element 100 according to a fourth embodiment of the disclosure.

[0157] The following will exclusively address differences between this fourth embodiment of the shielding element 100 and the previously described embodiments of the shielding element 100. Equivalent configurations will not be explained repeatedly and may, in particular, correspond to the previous embodiments of the shielding element 100.

[0158] In this fourth embodiment of the shielding element 100, the base body 102 is designed as a multi-layer base body 102.

[0160] The electrically conductive layer 104 is arranged between the outer layer 132 and the inner layer 134.

[0161] Preferably, the electrically conductive layer 104 is arranged between the outer layer 132 and the inner layer 134 in such a way that it is exposed to the inner side 110 in the region of the coupling device 114. The electrically conductive contact section 126 is thus formed by the electrically conductive layer 104 in the region of the coupling device 114.

[0162] In this way, in this multi-layer design of the base body 102, the electrically conductive contact section 126 can be formed in the region of the coupling device 114.

[0163] The outer layer 132 and the inner layer 134 of the multi-layer base body 102 are preferably formed from the same material. In particular, the outer layer 132 and / or the inner layer 134 are formed by an injection molding process, a foam injection molding process, an injection-compression molding process, or a compression molding process, in which the electrically conductive layer 104 is arranged between the outer layer 132 and the inner layer 134.
