Abstract
Official abstract text for this publication.
A retaining structure for a terminal fitting includes: a terminal fitting which has a cylindrical electric contact portion at a front end side and an electric wire connecting portion at a rear end side; a housing with which a cylindrical portion is integrally formed; a terminal accommodating chamber which is provided inwards of the cylindrical portion and which accommodates the terminal fitting with a moving gap left; and locking lances which are formed on a cylindrical wall portion of the cylindrical portion so as not to project from an outer circumferential surface thereof and which lock a lance locking portion of the terminal fitting which is inserted into the terminal accommodating chamber so as to retain the terminal fitting in such a way as to enable a radial movement of the terminal fitting while restricting a rearward withdrawal of the terminal fitting.
First claim
Opening claim text (preview).
What is claimed is: 1. A retaining structure for a terminal fitting, the structure comprising: a terminal fitting which has a electric contact portion at a front end side and an electric wire connecting portion at a rear end side thereof, the electric contact portion has a cylindrical outer surface; and a housing with which a cylindrical portion is integrally formed, wherein the cylindrical portion includes a cylindrical wall that defines a terminal accommodating chamber which is provided inwards of the cylindrical portion and which accommodates the terminal fitting with a moving gap left which enables a radial movement of the electric contact portion; and wherein a plurality of locking lances are formed on a cylindrical wall portion of the cylindrical portion so as not to project from an outer circumferential surface thereof, the plurality of locking lances normally hold the electric contact portion such that an entire cylindrical outer surface of the electric contact portion is spaced apart from the cylindrical wall by the moving gap, and the plurality of locking lances lock a lance locking portion of the terminal fitting which is inserted into the terminal accommodating chamber so as to retain the terminal fitting in such a way as to enable a radial movement of the terminal fitting while restricting a rearward withdrawal of the terminal fitting. 2. The retaining structure for a terminal fitting according to claim 1 , wherein the plurality of locking lances of three or more are provided along a circumferential direction of the cylindrical portion. 3. The retaining structure for a terminal fitting according to claim 1 , wherein the lance locking portion which is locked by the locking lances is formed on the electric contact portion by folding back an electric contact portion leading end so as to be laid on to an outer circumferential surface of the electric contact portion. 4. The retaining structure for a terminal fitting according to claim 1 , wherein leading end sides of the plurality of locking lances are respectively free ends.
