Abstract
Abstract A female terminal which enables a tab of a male terminal to be fitted into a female terminal even if the tab is bent when a connector housing receiving the male terminal is fitted relative to a connector housing receiving the female terminal. An elastic engagement arm is provided within a terminal receiving chamber in a connector housing. A female terminal includes a fitting portion for receiving a male terminal, an engagement portion for being retained by the engagement arm, and a wire connection portion. A guide projection is formed on the fitting portion of the female terminal, the guide projection projecting forwardly beyond the front end surface of the female terminal. There is provided a slanting guide surface extending from the guide projection 18 to an inlet of the fitting portion. A groove for allowing the passage of the guide projection therethrough is formed in the engagement arm.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
139 words
A female terminal insertable into a terminal receiving chamber in a connector housing comprising: an engagement portion for being retainingly held against an elastic engagement arm provided in the terminal receiving chamber; a base plate portion for being held against that surface of the terminal receiving chamber disposed opposite to that surface of said terminal receiving chamber from which the engagement arm projects; a wire connection portion formed at a rear end of the female terminal; and a fitting portion formed at a front end of the female terminal, wherein a guide projection is formed on that surface of the fitting portion facing away from the base plate portion, the guide projection projecting forwardly beyond a front end surface of the female terminal, wherein the guide projection includes a guide surface slanting towards an inlet of the fitting portion.
Claim 2
Dependent Claim
139 words
A female terminal insertable into a terminal receiving chamber in a connector housing comprising: an engagement portion for being retainingly held against an elastic engagement arm provided in the terminal receiving chamber; a base plate portion for being held against that surface of the terminal receiving chamber disposed opposite to that surface of said terminal receiving chamber from which the engagement arm projects; a wire connection portion formed at a rear end of the female terminal; and a fitting portion formed at a front end of the female terminal, wherein a guide projection is formed on that surface of the fitting portion facing away from the base plate portion, the guide projection projecting forwardly beyond a front end surface of the female terminal, wherein the guide projection includes a guide surface slanting towards an inlet of the fitting portion.
Claim 3
Dependent Claim
98 words
A female terminal and a connector housing therefore, wherein the female terminal is insertable into a terminal receiving chamber of the connector housing comprising; a fitting portion formed at one end of the female terminal having a front end with an inlet; a guide projection coupled to the front end of the fitting portion; an engagement portion; and an engagement arm provided in the terminal receiving chamber, wherein a groove is formed in the engagement arm for avoiding an interference of the engagement arm with the guide projection when inserting the female terminal into the terminal receiving chamber.
Claim 4
Dependent Claim
98 words
A female terminal and a connector housing therefore, wherein the female terminal is insertable into a terminal receiving chamber of the connector housing comprising; a fitting portion formed at one end of the female terminal having a front end with an inlet; a guide projection coupled to the front end of the fitting portion; an engagement portion; and an engagement arm provided in the terminal receiving chamber, wherein a groove is formed in the engagement arm for avoiding an interference of the engagement arm with the guide projection when inserting the female terminal into the terminal receiving chamber.
Claim 5
Dependent Claim
57 words
A female terminal and a connector housing therefor according to claim 2, wherein the engagement arm is disposed in the terminal receiving chamber towards the inlet of the fitting portion; and the engagement arm engaging the engagement portion of the fitting portion of the female terminal when the female terminal is inserted into the terminal receiving chamber.
Claim 6
Dependent Claim
44 words
