Abstract
Abstract A locking pin of a connector has slits which are provided through each body 31 of the locking pin, and has bridge elastic portions provided so as to be continuous in the pin insertion direction and so as to have elasticity in the direction to press terminals against walls of terminal accommodating chambers, the locking pin being inserted between the terminals and a wall, opposite to the terminals, of the locking pin insertion hole. Accordingly, the variation in size of the respective portions can be absorbed so that each pin body can be inserted into the locking pin insertion hole easily, and the terminals can be prevented from rattling in the terminal accommodating chambers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A connector with a double locking mechanism comprising: a connector housing having a plurality of terminal accommodating chambers; terminals insertable into said terminal accommodating chambers, respectively; locking means for fixing said terminals in said terminal accommodating chambers, respectively, said locking means being provided within said terminal accommodating chamber; and a locking pin detachably insertable into a locking pin insertion hole in an insertion direction from an outer side surface of said connector housing, said insertion hole being positioned between said terminals and a wall surface opposing said terminal, wherein said locking pin includes bridge elastic portions having elasticity in a direction normal to said insertion direction so as to press said terminals against an interior wall of said terminal accommodating chamber and wherein said bridge elastic portions are continuous and smooth without any cantilever-type fingers projecting therefrom in said insertion direction.
Claim 2
Dependent Claim
141 words
A connector with a double locking mechanism comprising: a connector housing having a plurality of terminal accommodating chambers; terminals insertable into said terminal accommodating chambers, respectively; locking means for fixing said terminals in said terminal accommodating chambers, respectively, said locking means being provided within said terminal accommodating chamber; and a locking pin detachably insertable into a locking pin insertion hole in an insertion direction from an outer side surface of said connector housing, said insertion hole being positioned between said terminals and a wall surface opposing said terminal, wherein said locking pin includes bridge elastic portions having elasticity in a direction normal to said insertion direction so as to press said terminals against an interior wall of said terminal accommodating chamber and wherein said bridge elastic portions are continuous and smooth without any cantilever-type fingers projecting therefrom in said insertion direction.
Claim 3
Dependent Claim
54 words
A connector with a double locking mechanism according to claim 1, wherein said locking pin has slits extending in the axial direction of said locking pin so as to define said bridge elastic portions, said slits being positioned so as to oppose said terminals when said locking pin is attached to said connector housing.
Claim 4
Dependent Claim
68 words
A connector with a double locking mechanism according to claim 1, wherein said locking pin has a corrugated configuration including a plurality of first convex portions on one side thereof and a plurality of second convex portions on an opposite side thereof, wherein said plurality of first convex portions respectively define said bridge elastic portions and said plurality of second convex portions abut against said opposing wall surface.
Claim 5
Dependent Claim
24 words
The connector with a double locking mechanism according to claim 1, wherein said insertion pin includes connecting portions which interconnect adjacent bridge elastic portions.
Claim 6
Dependent Claim
31 words
The connector with a double locking mechanism according to claim 4, wherein said bridge elastic portions include arcuate walls, opposite ends of said walls be joined to adjacent said connecting portions.
Claim 7
Dependent Claim
38 words
The connector with a double locking mechanism according to claim 5, wherein said arcuate walls have a convex shape so as to elastically abut against said terminals when said insertions pin is fully inserted into said connector housing.
