Abstract

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.

First claim

1 . A ferrite core built-in connector, comprising:
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 being 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.

2 . The ferrite core built-in connector of claim 1 , wherein:
at least one of the plurality of terminal fittings includes a coupling portion extending in a plate width direction of the intermediate portion from an end part of the intermediate portion on the first connecting portion side and the first connecting portion coupled to the intermediate portion by the coupling portion is arranged at a position shifted from an extension of the coupling portion in the plate width direction, and the first connecting portions of the plurality of terminal fittings overlapped in the plate thickness direction in the intermediate portions are separated from each other across a gap and arranged in parallel in the plate width direction.

3 . The ferrite core built-in connector of claim 2 , wherein:
at least one of the terminal fittings including the coupling portion includes a stepped portion bent into a crank shape in the plate thickness direction on the coupling portion and the intermediate portion and the first connecting portion provided on both sides of the stepped portion are arranged at height positions shifted from each other in the plate thickness direction, and the first connecting portions of the plurality of terminal fittings overlapped in the plate thickness direction in the intermediate portions are arranged at the same height position in the plate thickness direction by the stepped portion.

4 . The ferrite core built-in connector of claim 1 , wherein the connector housing is made of a resin material having a higher heat resistance than PVC.

5 . The ferrite core built-in connector of claim 1 , wherein the connector housing includes a terminal holding portion for holding parts of the plurality of terminal fittings except the first and second connecting portions in an embedded state and a core holding portion molded integrally with the terminal holding portion, the core holding portion holding the ferrite core in an embedded state.

6 . The ferrite core built-in connector of claim 1 , wherein the connector housing includes a first resin portion for holding parts of the plurality of terminal fittings except the first and second connecting portions in an embedded state and a second resin portion molded separately from the first resin portion, the second resin portion holding the first resin portion and the ferrite core in an embedded state.

7 . The ferrite core built-in connector of claim 1 , wherein the connector housing includes an exposure hole for exposing the ferrite core.

8 . The ferrite core built-in connector of claim 1 , wherein the first and second connecting portions of each terminal fitting respectively project and are exposed from the connector housing on both axial sides of the tubular ferrite core.
