Abstract
Abstract A connector housing comprising a housing body having a terminal receiving chamber for receiving a terminal connected with a lead wire, a tapered portion formed on an inner wall of the terminal receiving chamber in such a manner as to be converged in a direction of insertion of the terminal, and first and second locking means formed on an outer periphery of the housing body; a cover for preventing disengagement of the terminal, having first and second engaging portions to be engaged with the first and second locking means, respectively, a terminal insertion hole into which the terminal is inserted, and a flexible projection provided around the terminal insertion hole; and an elastically deformable soft band for integrally connecting the housing body with the cover; wherein the terminal is inserted under a first engaging condition where the second locking means of the housing body is merely in contact with the second engaging portion of the cover, and the flexible projection is urged along the tapered portion to stop a rear end of the terminal under a second engaging condition where the second locking means is fixedly engaged with the second engaging portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
A connector housing comprising: a housing body having a terminal receiving chamber for receiving a terminal connected with a lead wire, a tapered portion formed on an inner wall of said terminal receiving chamber is such a manner as to be converged in a direction of insertion of said terminal, and first and second locking means formed on an outer periphery of said housing body; a cover for preventing disengagement of said terminal, having first and second engaging portions to be engaged with said first and second locking means, repsectively, a terminal insertion hole into which said terminal is inserted, and a flexible projection provided around said terminal insertion hole; and an elastically deformable soft band for integrally connecting said housing body with said cover; wherein said terminal is inserted under a first engaging condition where said second locking means of said housing body is merely in contact with said second engaging portion of said cover, and said flexible projection is urged along said tapered portion to stop a rear end of said terminal under a second engaging condition where said second locking means is fixedly engaged with said second engaging portion.
Claim 2
Dependent Claim
192 words
A connector housing comprising: a housing body having a terminal receiving chamber for receiving a terminal connected with a lead wire, a tapered portion formed on an inner wall of said terminal receiving chamber is such a manner as to be converged in a direction of insertion of said terminal, and first and second locking means formed on an outer periphery of said housing body; a cover for preventing disengagement of said terminal, having first and second engaging portions to be engaged with said first and second locking means, repsectively, a terminal insertion hole into which said terminal is inserted, and a flexible projection provided around said terminal insertion hole; and an elastically deformable soft band for integrally connecting said housing body with said cover; wherein said terminal is inserted under a first engaging condition where said second locking means of said housing body is merely in contact with said second engaging portion of said cover, and said flexible projection is urged along said tapered portion to stop a rear end of said terminal under a second engaging condition where said second locking means is fixedly engaged with said second engaging portion.
Claim 3
Dependent Claim
59 words
The connector housing as defined in claim 1, wherein said first locking mans comprises a pair of projections formed on both side surfaces of said housing body, and said second locking means comprises a first projection formed at an upper central portion of said housing body and a second projection formed at lower both ends of said housing body.
Claim 4
Dependent Claim
30 words
The connector housing as defined in claim 1, wherein said flexible projection comprises a plurality of tongue-like members arranged in parallel relationship with an axis of said terminal insertion hole.
Claim 5
Dependent Claim
27 words
The connector housing as defined in claim 1, wherein said flexible projection comprises a plurality of tongue-like members converged toward an axis of said terminal insertion hole.
Claim 6
Dependent Claim
34 words
The connector housing as defined in claim 1, wherein said terminal insertion hole of said cover is substantially axially aligned with said terminal receiving chamber of said housing body under said first engaging condition.
Claim 7
Dependent Claim
40 words
The connector housing as defined in claim 1, wherein said cover is provided at its upper portion with a U-shaped flexible member, and said second engaging condition is obtained by inwardly depressing both side surfaces of said U-shaped flexible member.
