Abstract

Abstract In the connector of the present invention, terminals are locked in their associated passages by causing projections provided near the free end of cantilever-like resilient arms in such a manner as to project inwardly of the respective passages to fit in associated recesses formed in the terminals accommodated in the passages. An individually formed fixing member is mounted over the place where the resilient arms are formed to prevent the arms from being deflected outwardly.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 300 words
A connector comprising: a pair of housings each having a pair of tubular portions having passages therein for having terminals introduced thereinto in one direction along the length of said passages and being accomodated in said passages, said tubular portions having cuts in one of the side walls thereof for defining cantilever-like resilient arms having projections on the free ends thereof and extending in the direction in which terminals are introduced into said passages for locking terminals in said passages by causing said projections to fit in recesses in the terminals accomodated in the passages; a fixing member movable over the portions of said tubular portions to a finally locked position where said resilient arms are provided, said fitting means having temporary locking means thereon for temporarily locking said fixing member onto said tubular portions at a temporarily locked position spaced from the portions of the side wall of said tubular portions where said resilient arms are provided, said tubular portions in one of said housings being parallel to each other and spaced in a direction normal to the side walls to form a gap therebetween, and said fixing member on the tubular portions of the other of said housings further having a guide piece thereon projecting in a direction away from said other housing and fittable into said gap, whereby when said connector is assembled by moving said housings toward each other, said guide piece moves into said gap between said tubular portions on said one housing for guiding terminals in said other housing into the tubular portions of said one housing, and at the same time said fixing member on the tubular portions of said other housing is moved onto said tubular portions of said other housing from the temporarily locked position to the finally locked position thereof.
Claim 2
Dependent Claim 300 words
A connector comprising: a pair of housings each having a pair of tubular portions having passages therein for having terminals introduced thereinto in one direction along the length of said passages and being accomodated in said passages, said tubular portions having cuts in one of the side walls thereof for defining cantilever-like resilient arms having projections on the free ends thereof and extending in the direction in which terminals are introduced into said passages for locking terminals in said passages by causing said projections to fit in recesses in the terminals accomodated in the passages; a fixing member movable over the portions of said tubular portions to a finally locked position where said resilient arms are provided, said fitting means having temporary locking means thereon for temporarily locking said fixing member onto said tubular portions at a temporarily locked position spaced from the portions of the side wall of said tubular portions where said resilient arms are provided, said tubular portions in one of said housings being parallel to each other and spaced in a direction normal to the side walls to form a gap therebetween, and said fixing member on the tubular portions of the other of said housings further having a guide piece thereon projecting in a direction away from said other housing and fittable into said gap, whereby when said connector is assembled by moving said housings toward each other, said guide piece moves into said gap between said tubular portions on said one housing for guiding terminals in said other housing into the tubular portions of said one housing, and at the same time said fixing member on the tubular portions of said other housing is moved onto said tubular portions of said other housing from the temporarily locked position to the finally locked position thereof.
Claim 3
Dependent Claim 100 words
A connector as claimed in claim 1 in which said tubular portions on said other of said housings are also parallel to and spaced from each other and have a gap therebetween, and said fixing member on the tubular portions in said other of said housings has a further guide piece projecting in the opposite direction from said firstmentioned guide piece and fittable into the gap between the tubular portions of said other of said housings for guiding said fixing member onto said tubular portions from the temporarily locked position to the finally locked position during assembly of said connector.
