Abstract
Abstract A connector with a double retaining mechanism which allows a cover member closing operation to be performed reliably as well as easily without providing a hinge portion, and allows a connecting terminal accommodated in a terminal accommodating chamber to be doubly retained reliably by a cover member. A connector with a double retaining mechanism allows a female terminal to be unreleasably retained by a release preventing lance with the female terminal inserted into a terminal accommodating chamber formed in a housing. When a cover member that covers an opening in the rear of the terminal accommodating chamber closes a rear portion of the housing, coupling portions arranged on a base end portion of the cover member are cut off while twisted. At this time, a claw arranged on the base end portion of the cover member retains the female terminal in an axial direction while confronting the inner surface of an upper wall, further, retaining lock arms arranged in the rear of the cover member are retained by engaging portions of the housing.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
75 words
A connector, comprising: a housing having at least two side walls; a terminal accommodating chamber, for accommodating a terminal, formed in said housing; and a cover member, for retaining said terminal in said terminal accommodating chamber, said cover member being integrally connected to said housing by coupling portions formed on at least two side portions of said cover member, wherein when said cover member is twisted to a closed position, said coupling portions are severed.
Claim 2
Dependent Claim
75 words
A connector, comprising: a housing having at least two side walls; a terminal accommodating chamber, for accommodating a terminal, formed in said housing; and a cover member, for retaining said terminal in said terminal accommodating chamber, said cover member being integrally connected to said housing by coupling portions formed on at least two side portions of said cover member, wherein when said cover member is twisted to a closed position, said coupling portions are severed.
Claim 3
Dependent Claim
30 words
The connector of claim 1, further comprising at least one claw formed on said cover member wherein said coupling portions are severed by pivoting said cover member about said claw.
Claim 4
Dependent Claim
39 words
The connector of claim 2, wherein said at least one claw is arranged so as to correspond to said terminal accommodating chamber close to a base end portion of said cover member on which said coupling portions are formed.
Claim 5
Dependent Claim
20 words
The connector of claim 3, wherein said claw retains said terminal in accordance with the pivoting of said cover member.
Claim 6
Dependent Claim
30 words
The connector of claim 1, further comprising at least one claw formed on said cover member wherein said coupling portions are severed by pivoting said cover member about said claw.
Claim 7
Dependent Claim
39 words
The connector of claim 5, wherein said at least one claw is arranged so as to correspond to said terminal accommodating chamber close to a base end portion of said cover member on which said coupling portions are formed.
Claim 8
Dependent Claim
20 words
The connector of claim 6, wherein said claw retains said terminal in accordance with the pivoting of said cover member.
Claim 9
Dependent Claim
30 words
The connector of claim 1, wherein each of said coupling portions has a large diameter portion on the cover member side and a small diameter portion on the housing side.
Claim 10
Dependent Claim
28 words
The connector of claim 1, wherein a recess, for engaging with a lance formed on said terminal, is formed in a bottom wall of said terminal accommodating chamber.
Claim 11
Dependent Claim
46 words
The connector of claim 1, wherein said at least two side walls of said housing include notched portions configured and dimensioned to receive said coupling portions when said cover member is in its closed position to thereby aid in retaining said cover member on said housing.
Claim 12
Dependent Claim
19 words
The connector of claim 1, further comprising engaging portions on said at least two side walls of said housing.
Claim 13
Dependent Claim
25 words
The connector of claim 11, wherein the engaging portions project from inner surfaces of the side walls of the housing toward the terminal accommodating chamber.
Claim 14
Dependent Claim
43 words
The connector of claim 11, further comprising lock arms formed on said cover member to engage with said engaging portions of said housing when said cover member, in its closed position, covers an opening in a rear portion of said terminal accommodating chamber.
Claim 15
