Waterproof connector and method of assembling the same

A method of assembling a waterproof connector, which accommodates terminals having electric wires to be connected thereto into a plurality of terminal accommodation compartments of a connector housing and seals said plurality of terminal accommodation compartments and said electric wires by use of rubber plugs, thereby assembling said waterproof connector, comprising:

• inserting said rubber plugs into rubber plug accommodation recessed portions on an inner side of one wall portion of a seal housing that forms an inner shell of said connector housing;
• accommodating said terminals into said plurality of terminal accommodation compartments of an inner housing that is to be connected to said seal housing and forms an inner shell of said connector housing;
• passing said electric wires through said rubber plugs via a plurality of electric wire insertion-through-holes of said one wall portion of said seal housing, from the outside thereof;
• reaching said electric wires passed through, up to positions of said terminals accommodated within said plurality of terminal accommodation compartments;
• moving said inner housing and said seal housing relatively to each other in a direction intersecting an axial direction of said electric wires at substantially right angles thereto, thereby correspondingly connecting said electric wires to said terminals;
• and
• detachably fitting said inner housing and said seal housing into an outer housing forming an outer shell of said connector housing from a rear side thereof.

A waterproof connector comprising:

• an inner housing having at least one terminal accommodation compartment with at least one terminal configured to receive an electric wire;
• a seal housing configured to connect to said inner housing in such a way as to be movable relative to said inner housing in a direction that intersects an axial direction of the electric wire substantially at right angles thereto, a wall portion of said seal housing that opposes said at least one terminal accommodation compartment having formed therein at least one insertion-through-hole configured to receive the electric wire therethrough, said wall portion having formed therein at least one rubber plug accommodation recessed portion into which a rubber plug can be accommodated at positions on an inner side of said wall portion that oppose said at least one insertion-through-hole, said rubber plug being configured to seal said at least one terminal accommodation compartment and the electric wire;
• and
• an outer housing configured to detachably receive said inner housing and said seal housing.
