Waterproof connector

1. A waterproof connector comprising:

an outer housing having an internal space, a first opening on a first side thereof and a second opening on a second side thereof;

an inner housing having a first and second areas in which different kinds of terminals are mounted, said inner housing being fitted to said first opening of said outer housing;

a waterproof plug through which a plurality of wires connected to said terminals pass in a sealing manner, said waterproof plug being fitted to said second opening;

a sealing material filled in said internal space of said outer housing between said inner housing and said waterproof plug;

wherein a centerline of said first opening and a centerline of said second opening are offset a predetermined amount from each other so that a density of said wires is made generally uniform in said internal space of said outer housing,

wherein an inclined surface is formed on a predetermined portion of an inner surface of said outer housing in said internal space so as to oppose to said inner housing and wherein said inclined surface tapers towards said centerline of said first opening.

2. A waterproof connector according to claim 1 , wherein said first opening has a larger area than said second opening.

3. A waterproof connector according to claim 1 , wherein said inclined surface is formed on the second side of the outer housing.

4. A waterproof connector according to claim 1 , wherein a communication hole communicating said first opening of said outer housing with said internal space is formed in the first area of said inner housing in which large-size terminals are mounted, and when the sealing material is filled in said internal space, a filling nozzle for supplying said sealing material is inserted into said internal space through said communication hole.

5. A waterproof connector according to claim 1 ,

when the sealing material is filled in said internal space, said inclined surface guides the sealing material from a filling nozzle inserted into said internal space through a communication hole formed in said inner housing.

6. A waterproof connector comprising:

an outer housing having an internal space, a first opening on a first side thereof and a second opening on a second side thereof;

an inner housing having a first and second areas in which different kinds of terminals are mounted, said inner housing being fitted to said first opening of said outer housing;

a waterproof plug through which a plurality of wires connected to said terminals pass in a sealing manner, said waterproof plug being fitted to said second opening;

a sealing material filled in said internal space of said outer housing between said inner housing and said waterproof plug;

wherein a centerline of said first opening and a centerline of said second opening are offset a predetermined amount from each other so that a density of said wires is made generally uniform in said internal space of said outer,

wherein an inclined surface is formed on a predetermined portion of an inner surface of said outer housing in said internal space so as to oppose to said inner housing, and

when the sealing material is filled in said internal space, said inclined surface guides the sealing material from a filling nozzle inserted into said internal space through a communication hole formed in said inner housing,

wherein a guide groove is formed in the inner surface of said outer housing over an entire periphery of said internal space, and when the sealing material is filled in said internal space, the sealing material flows into said guide groove via said inclined surface; and

a plurality of notches are formed in said guide groove at predetermined intervals along the periphery of said guide groove, and the sealing material is flowed from said guide groove via said notches toward the second side of said internal space.
