Abstract

A terminal fitting ( 10 ) includes a body ( 11 ) in the form of a rectangular tube, a tab ( 41 ) of a mating terminal ( 40 ) being inserted into the body ( 11 ) from the front. A resilient contact piece ( 22 ) is accommodated in the body ( 11 ). The tab ( 41 ) is sandwiched resiliently in a plate thickness direction thereof between the resilient contact piece ( 22 ) and a receiving plate ( 15 ) of the body ( 11 ). Holding portions ( 30 ) are formed integrally to the resilient contact piece ( 22 ) and capable of holding the tab ( 41 ) with a relative displacement of the tab ( 41 ) in a width direction with respect to the resilient contact piece ( 22 ) restricted by coming into contact with side edges ( 41 S) of the tab ( 41 ).

First claim

What is claimed is:

1. A terminal fitting assembly, comprising:
a body in the form of a rectangular tube, a tab of a mating terminal is inserted into the body;
a resilient contact piece accommodated in the body, the tab being resiliently sandwiched in a plate thickness direction thereof between a flat surface of the resilient contact piece and a receiving plate of the body; and
a holding portion integrally formed to the resilient contact piece and rising, substantially at a right angle from a side part of the flat surface, the holding portion being capable of holding the tab with a relative displacement of the tab in a width direction with respect to the resilient contact piece restricted by coming into contact with a side edge part of the tab, the holding portion being resiliently displaceable in the width direction with respect to the resilient contact piece.

2. The terminal fitting assembly of claim 1 , wherein:
the resilient contact piece includes a base end connected to the body, the flat surface extending from the base end along an inserting direction of the tab, a curved surface connected to an extending end of the flat surface and a contact point formed on the curved surface, the contact point being capable of contacting the properly inserted tab.

3. The terminal fitting assembly of claim 2 , wherein the holding portion includes a rising portion connected to the flat surface and a contact portion extending from the rising portion toward the contact point, the contact portion being capable of coming into contact with the tab.

4. A terminal fitting assembly, comprising:
a body in the form of a rectangular tube, a tab of a mating terminal being inserted into the body;
a resilient contact piece accommodated in the body, the tab being resiliently sandwiched in a plate thickness direction thereof between the resilient contact piece and a receiving plate the body;
a holding portion integrally formed to the resilient contact piece, the holding portion being capable of holding the tab with a relative displacement of the tab in a width direction with respect to the resilient contact piece restricted by coming into contact with a side edge part of the tab; and
an excessive deflection restricting portion formed on a side plate of the body, the excessive deflection restricting portion being configured to restricting deformation of the resilient contact piece beyond a resilient limit by having an outer surface of the holding portion brought into contact therewith.

5. The terminal fitting assembly of claim 4 , wherein the holding portion is resiliently displaceable in the width direction with respect to the resilient contact piece.

6. The terminal fitting assembly of claim 4 , further comprising a deflection suppressing portion formed on a side plate of the body, the deflection suppressing portion being capable of suppressing deformation of the resilient contact piece in the width direction by having a side of the tab resiliently brought into contact therewith, wherein:
the excessive deflection restricting portion is capable of restricting deformation of the deflection suppressing portion beyond a resilient limit by having an outer surface of the deflection suppressing portion brought into contact therewith.

7. The A terminal fitting assembly, comprising:
a body in the form of a rectangular tube, a tab of a mating terminal being inserted into the body;
a resilient contact piece accommodated in the body, the tab being resiliently sandwiched in a plate thickness direction thereof between the resilient contact piece and a receiving plate the body;
a holding portion integrally formed to the resilient contact piece, the holding portion being capable of holding the tab with a relative displacement of the tab in a width direction with respect to the resilient contact piece restricted by coming into contact with a side edge part of the tab; and
a deflection suppressing portion formed on a side plate constituting the body, the deflection suppressing portion being capable of suppressing deformation of the resilient contact piece in the width direction by having a side edge part of the tab resiliently brought into contact therewith.
