  • Patent number: 10804625
    Abstract: A terminal includes a connecting portion, a cover fixing portion configured to fix a cover of an electric wire, and a conductor fixing portion configured to fix a conductor core wire exposed from the cover of the electric wire. The conductor fixing portion has a holding portion which has an insertion portion and is configured to hold at least one side of the conductor core wire inserted into the insertion portion, and an elastic deformation portion which does not allow the conductor core wire to be inserted through the insertion portion by interference between the elastic deformation portion and the conductor core wire when the elastic deformation portion is at an initial position and which allows the conductor core wire to be inserted through the insertion portion when the elastic deformation portion is at a deformed position.

  • Patent number: 10756450
    Abstract: A terminal is to be connected to an electric wire including a conductor core wire and a sheath covering the conductor core wire. The terminal includes a connection portion and a conductor fixing portion which is located rearward of the connecting portion and configured to fix the conductor core wire exposed from the electric wire. The connection portion and the conductor fixing portion are integrally formed to each other and are extended in a front-rear direction. The conductor fixing portion has through holes penetrating in a thickness direction of the conductor fixing portion. An end edge portion of each of the plurality of through holes on an outer peripheral surface side of the conductor fixing portion is provided with a tapered portion that increases in diameter of the tapered portion toward an outer peripheral surface of the conductor fixing portion.

  • Patent number: 8251743
    Abstract: Terminal insert holes 61 are provided in a spacer 60 inserted into an inner housing. In each of the terminal insert holes 61, a lance 62 is provided. The lance is arranged in an obliquely upper position relative to the vertical direction and the transverse direction seen from a central part of the terminal insert hole 61. A bending direction of each lance is set to a direction substantially corresponding to the oblique direction. Further, in the spacer 60, an engaging protrusion part 63 is provided as a mainly terminal engaging part. Thus, the spacer is pushed in to a mainly engaged position from a temporarily engaged position to shift a temporary engagement by the lance to a main engagement by the engaging protrusion part.
