Abstract
A waterproof structure is achieved by inserting a covered electric wire 40 obtained by covering an outer periphery of a conductor portion 41 with a cover portion 42 made of a resin into an electric wire inserting hole 28 of a connector main body 21 inserted to a terminal receiving chamber 24 in a state of being connected to a terminal received in a terminal receiving chamber 24 of the connector main body 21 and welding the cover portion 42 and the electric wire inserting hole 28 in accordance with a ultrasonic oscillation and a pressurization from an outer side. The connector main body 21 has a weld depth setting portion 47 for setting a weld depth, whereby an excessive welding is prevented.
Claims6
A waterproof connector comprising:
- a connector main body comprising
- a terminal receiving chamber,
- a side wall having a first weld line portion, and
- a wire receiving table having a first wire receiving groove;
- a wire having a cover portion made of a resin;
- a cover comprising
- a side wall portion including a second weld line portion, and
- a cover surface portion including a second wire receiving groove aligned with said first wire receiving groove thereby forming a wire receiving hole;
- and
- a weld depth setting portion for setting a weld depth at a time of welding, the weld depth setting portion comprising a contact portion and a receiving portion, wherein said contact portion is provided in one of said wire receiving table and said cover, and said receiving portion is provided in the other of said wire receiving table and said cover,
- wherein said wire is received in said wire receiving hole, said cover covers said wire receiving table, said receiving portion and said contact portion are brought into contact with each other thereby setting the weld depth, said cover portion is welded to said terminal receiving chamber and said first weld line portion is welded to said second weld line portion resulting in a waterproof connection, wherein said receiving portion and said contact portion are not welded together.
