Abstract

The branch portion includes: a first circuit portion electrically connected to the main wire while extending to a leading end from a base end of the branch portion; a second circuit portion electrically connected to the main wire while extending to the leading end from the base end of the branch portion and electrically connected to the first circuit portion at the leading end of the branch portion; and a ground conductor that is disposed between the first circuit portion and the second circuit portion while extending to the leading end from the base end of the branch portion and has one end to be grounded and the other end to be opened.

Description

technical field [0001] The present invention relates to a noise removing circuit of a wire harness mounted on, for example, a vehicle and a wire harness assembly including the noise removing circuit. Background technique [0002] From the past, various noise removal circuits have been used for removing electrical noise carried by wire harnesses. For example, noise removal circuits for wiring harnesses have frequently been used in Figure 19 In the vehicle shown (see JP 2009-111832 A). [0003] Figure 19 The shown noise removal circuit 510 of the wire harness WH is a circuit in which electric wires 61 and 62 serving as objects of noise removal are branched from a main wire 6 bundled with a plurality of electric wires 60, 61, and 62, and noise is configured in a unit form. The filter portion 501 is connected to the front ends of the electric wire branch portions 61a and 62a, and the noise filter portion 501 is fixed to the vehicle body panel with bolts and thereby grounded (...
