Waterproof connector and method for assembling same
First Claim
1. A waterproof connector comprising a housing, a terminal connected to an end of an electric wire and accommodated in the housing, and a soft sealing material accommodated in the housing and in tight contact with an outer circumference of the electric wire and an inner wall of the housing, for sealing an inside of the housing, wherein:
- the housing comprises a housing body, and a terminal housing assembled to the housing body and provided with a terminal accommodation portion for accommodating the terminal;
an open end of the terminal housing accomodation chamber configured to receive the terminal housing abuts the contact part of the terminal in the contact part accomodation chamber of the terminal housing, and acts as a stopper for preventing the terminal from slipping out of the terminal accomodation portion;
the housing body has a sealing material accommodation chamber for accommodating the soft sealing material, an insertion hole provided in the inner wall and configured to pass the electric wire through the inner wall with which the soft sealing material accommodated in the sealing material accommodation chamber is tight contact, and a terminal housing accommodation chamber communicating with the sealing material accommodation chamber, the terminal housing being fitted in the terminal housing accommodation chamber and compressing the soft sealing material against the inner wall and around the outer circumference of the electric wire; and
the terminal is connected to an end of the electric wire inserted through the insertion hole of the soft sealing material.

3. A method for assembling the waterproof connector of claim 1, comprising the steps of:
-
inserting the soft sealing material in the sealing material accomodation chamber;
inserting the electric wire into the housing body through the wire insertion hole, passing the wire through the soft sealing material, and pulling the wire to a side of the terminal housing accomodation chamber;
connecting the end of the wire to a wire connection part of the terminal;
inserting the terminal housing, with the terminal accommodated in the terminal accomodation portion, into the terminal housing accomodation chamber to push the soft sealing material toward the inner wall; and
bringing an open end of the terminal housing accomodation chamber in which the terminal housing is accommodated, into abutment on the terminal in the terminal accommodation portion to prevent the terminal from slipping out.
