  • Patent number: 9065194
    Abstract: A connector can prevent, at a low cost, a phenomenon that a crack develops in a resin molded member to which a screwing plate portion of a terminal fitting is fixed due to a bending displacement of the screwing plate portion caused by fastening force of the screwing when the screwing plate portion is screwed to a terminal stage. A plate portion fixing portion 31, to which a screwing plate portion 11 of a terminal fitting 10 is fixed, of the connector housing 30 has a terminal escape space 31a adjacent to the screwing plate portion 11 on a destination side in a direction of fastening to a terminal stage 40. The terminal escape space 31a permits a bending displacement of the screwing plate portion 11 in the fastening direction.

  • Patent number: 9040845
    Abstract: A shielding structure for a wire harness includes a seal member which has a wire through hole that allows the wire to pass therethrough while sealing a circumference of the wire. The wire has a structure where an insulating resin layer is formed on an outer circumference of a conductor, and a predetermined range in a length direction of the conductor is coated with a shield layer formed by resin plating to cover an outer circumferential surface of the insulating resin layer. A terminal portion of the wire is passed through the wire through hole of the seal member to be introduced into the shield wall to a position where the shield layer exists, whereby an inner circumference of the wire through hole is made in close contact with the shield layer to cause the shield layer and the seal member to be electrically conducted with each other.
