A connector with a built-in ferrite core is disclosed which suppresses the damage of the ferrite core and has an excellent degree of freedom in selecting a resin material to be used. A connector 10 with a built-in ferrite core includes a terminal fitting 12, a ferrite core 14 to be arranged to surround the terminal fitting 12 and a connector housing 16 for accommodating the terminal fitting 12 and the ferrite core. The connector housing 16 includes a first resin portion 18 for holding the terminal fitting 12 in an embedded state and a second resin portion 20 for holding the first resin portion 18 and the ferrite core 14 in an embedded state.

A connector device electrically connected to a circuit board includes: a body portion connected externally; a housing surrounding at least a portion of the body portion; a first terminal extending downward from the body portion and connected to a first capacitor of the circuit board; a second terminal extending downward from the body portion to be spaced apart from the first terminal and connected to a second capacitor of the circuit board; and a ferrite core through which the second terminal passes.

A connecting assembly for electrically connecting a bus subscriber to a differential bus system comprises a differential main conductor portion, which has a first electrical main conductor and a second electrical main conductor. The differential main conductor portion has a first sub-portion and a second sub-portion, which is electrically connected to the first sub-portion. A first terminal for electrically connecting to a first mating terminal of the bus subscriber is formed in the first electrical main conductor between the first sub-portion and the second sub-portion, and a second terminal for electrically connecting to a second mating terminal of the bus subscriber is formed in the second electrical main conductor between the first sub-portion and the second sub-portion. The first and second electrical main conductors are surrounded, at least in the first sub-portion or in the second sub-portion, by one body in each case, said body being made of magnetizable material.

A ferrite core built-in connector is disclosed which suppresses the damage of a ferrite core and has an excellent degree of freedom in selecting a resin material to be used. A ferrite core built-in connector includes a plurality of terminal fittings each configured such that a first connecting portion and a second connecting portion are coupled by an intermediate portion having a strip plate shape, a ferrite core arranged to collectively surround the intermediate portions of the plurality of terminal fittings, and a connector housing for accommodating parts of the plurality of terminal fittings except the first and second connecting portions, and the ferrite core in an embedded state. The intermediate portions of the plurality of terminal fittings are separated from each other across a gap in a plate thickness direction and arranged to overlap each other in projection in the plate thickness direction.
