WIRE HARNESS MODULE FOR ANTI-ELECTROMAGNETIC INTERFERENCE
Disclosed in the present application is a wire harness module for anti-electromagnetic interference. The wire harness module comprises at least one layer of circuit board, at least two shielding layers, and at least one connector electrically connected to the circuit board and/or the shielding layers, wherein the circuit board and the shielding layers are placed in a stacked manner, and at least one layer of circuit board is arranged between adjacent shielding layers; and the connector comprises a sheath and at least one terminal that is at least partially arranged in the sheath, the terminal being electrically connected to a loop conductor and/or a shielding layer in the circuit board. Since a multi-layer shielding structure is used, space can be saved on; a shielding space can be formed between shielding layers, such that electromagnetic interference from the inside and electromagnetic interference on the outside can be reduced, and electromagnetic interference from the outside on an internal circuit board can also be reduced, thereby greatly improving the EMC performance of the whole vehicle; in addition, the present application has the characteristics of convenient installation, good flatness, saving on space, no need for additional shielding means, and a wide range of usage scenarios.
