## Abstract

A lance which protrudes from the outside surface of a terminal body to prevent falling out of a cavity of a connector housing includes a lance body of an inclined plate shape whose protruding length from the outer surface of the terminal body towards the outside gradually increases from the front end side of the terminal body to the back end side, and a shielding plate which extends from the back end edge of the lance body towards the outer surface of the terminal body so that an opening which opens towards a terminal back end is not formed between the back end edge of the lance body and the outer surface.

## Claims

### Claim 1

A terminal fitting comprising:
a terminal body which is formed by press molding a metal plate; and
a lance which is integrally formed with the terminal body so that the lance is capable of being elastically displaced in the terminal body and protrudes from an outside surface of the terminal body;
wherein when the terminal fitting is inserted into a cavity of a connector housing, the lance enters into a retaining recess formed in the cavity to prevent the terminal fitting from falling out of the cavity; and
wherein the lance includes:
a lance body which is formed into an inclined plate whose protruding length from the outer surface of the terminal body towards an outside gradually increases from a front end side of the terminal body to a back end side of the terminal body, and which is prevented from falling out of the cavity when a back end edge of the lance body is retained to the retaining recess; and
a shielding plate which extends from the back end edge of the lance body towards the outer surface of the terminal body so that an opening which opens towards a terminal back end is not formed between the back end edge of the lance body and the outer surface of the terminal body;
wherein a first outer wall plate part of the terminal body, which has the outside surface from which the lance protrudes outward, is provided with a lance opening through which the lance is movably inserted outward;
wherein the lance has back surface abutting parts, which are overlapped on a back surface of the first outer wall plate part at front and back of the lance opening and which abut against the back surface of the first outer wall plate part to regulate the lance from being displaced outward, at front and back ends of the lance;
wherein the terminal body includes:
a third outer wall plate part opposed to a second outer wall plate part connected to one end of the first outer wall plate part;
an overlapped wall which is connected to a front end or a back end of the third outer wall plate part, and which is overlapped on the back surface of the first outer wall plate part at the front end side or at the back end side of the first outer wall plate part; and
an overlapped piece which extends from the overlapped wall into a belt shape along a front-rear direction of the terminal body and which is overlapped on the back surface of the first outer wall plate part;
wherein the lance body and the shielding plate of the lance are formed by bending a part of the overlapped piece which faces the lance opening; and
wherein the overlapped wall clamps a male terminal, which is inserted into a terminal insertion part of the terminal body, together with the spring strip arranged in the terminal insertion part.
