Abstract
Abstract A spring mechanism ( 6 ) is provided at a portion of a connector housing ( 2 ). The spring mechanism ( 6 ) includes an insertion port ( 8 ), a retaining projection ( 10 ) and a leaf spring (9) retained by the retaining projection ( 10 ). A spring holder ( 17 ) for resiliently deforming the leaf spring ( 9 ), is provided at a terminal portion ( 3 ) to be received in a receiving portion ( 4 ). When the terminal portion ( 3 ) is inserted into the receiving portion ( 4 ), the leaf spring ( 9 ) is resiliently deformed by the spring holder ( 17 ). As a result, the whole of the terminal portion ( 3 ) is urged by the leaf spring ( 9 ), and a resilient-retaining piece portion ( 16 ), provided at the terminal portion ( 3 ), is retainingly engaged in a retaining portion ( 5 ) formed at the receiving portion ( 4 ), thereby eliminating a clearance between the connector housing and the terminal portion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A connector, comprising: a connector housing including a receiving portion formed therein; a terminal portion insertable into the receiving portion of the connector housing; a spring attachable to the connector housing so as to project into the receiving portion; a spring holder formed on a first side surface of the terminal portion, the spring holder pressing the spring so that the spring is resiliently deformed when the terminal portion is inserted into the receiving portion; a resilient-retaining piece portion formed on a second side surface of the terminal portion, the resilient-retaining piece portion being slid on an inner surface of the receiving portion while being resiliently deformed when the terminal portion is inserted into the receiving portion; and a retaining portion formed in the receiving portion, wherein, when the terminal portion is inserted into a predetermined position within the receiving portion, a whole of the terminal portion is pushed by the spring so that the resilient-retaining piece portion is retained by the retaining portion.
Claim 2
Dependent Claim
164 words
A connector, comprising: a connector housing including a receiving portion formed therein; a terminal portion insertable into the receiving portion of the connector housing; a spring attachable to the connector housing so as to project into the receiving portion; a spring holder formed on a first side surface of the terminal portion, the spring holder pressing the spring so that the spring is resiliently deformed when the terminal portion is inserted into the receiving portion; a resilient-retaining piece portion formed on a second side surface of the terminal portion, the resilient-retaining piece portion being slid on an inner surface of the receiving portion while being resiliently deformed when the terminal portion is inserted into the receiving portion; and a retaining portion formed in the receiving portion, wherein, when the terminal portion is inserted into a predetermined position within the receiving portion, a whole of the terminal portion is pushed by the spring so that the resilient-retaining piece portion is retained by the retaining portion.
Claim 3
Dependent Claim
24 words
The connector of claim 1 , wherein the spring is resilient in an axial direction of the terminal portion inserted into the receiving portion.
Claim 4
Dependent Claim
44 words
The connector of claim 1 , wherein when the terminal portion is inserted into the predetermined position within the receiving portion, the whole of the terminal portion is pushed by the spring in a direction opposite to an inserting direction of the terminal portion.
Claim 5
Dependent Claim
66 words
The connector of claim 1 , further comprising a step portion formed on the inner surface of the receiving portion, the step portion having a slanting surface, wherein when the terminal portion is inserted into the receiving portion, the resilient-retaining piece portion is slid on the slanting surface of the step portion, and goes beyond the step portion, and then is retained by the retaining portion.
Claim 6
Dependent Claim
17 words
The connector of claim 4 , wherein a part of the step portion defines the retaining portion.
Claim 7
Dependent Claim
60 words
The connector of claim 1 , further comprising a spring mechanism integrally formed in the connector housing, the spring mechanism including: the spring, an insertion port into which the spring is inserted from an outer side of the connector housing, and a retaining projection retaining one end of the spring while the other end of the spring is resiliently movable.
Claim 8
Dependent Claim
38 words
The connector of claim 6 , wherein the retaining projection retains one end of the spring while the other end of the spring is resilient in an axial direction of the terminal portion inserted into the receiving portion.
Claim 9
Dependent Claim
13 words
The connector of claim 7 , wherein the spring has a substantially U-shape.
Claim 10
Dependent Claim
13 words
The connector of claim 2 , wherein the spring has a substantially U-shape.
