Audio jack connector

摘要

An audio jack connector includes an insulating housing which has a base body defining a holding cavity in a bottom thereof and an inserting body defining an inserting chamber, a plurality of electrical terminals disposed in the base body, a fixing member fastened in the holding cavity of the insulating housing to cover and hold the electrical terminals in the base body, and a sealing tape covering under the fixing member and adhered outside the insulating housing and the fixing member to seal up splicing gaps between sidewalls of the holding cavity and peripheral edges of the fixing member. So the audio jack connector can effectively prevent the water vapor and dust passing through the inserting chamber onto a printed circuit board of an electronic product where the audio jack connector is used.

主权项

1. An audio jack connector, comprising:
an insulating housing having a base body and an inserting body which is integrally formed to one side of the base body, a front face of the inserting body being concaved rearward to form an inserting chamber, a bottom face of the base body defining a holding cavity of which a top inner wall defines a plurality of terminal grooves arranged alongside the inserting body and each further extending sideward through the inserting body to communicate with the inserting chamber; a plurality of electrical terminals disposed in the terminal grooves of the insulating housing, each electrical terminal having a contact portion projecting into the inserting chamber and a welding block located away from the inserting body; a fixing member fastened in the holding cavity of the base body, covering and holding the electrical terminals in the terminal grooves; and a sealing member including a sealing tape, the sealing tape completely covering the fixing member and being adhered outside the insulating housing and the fixing member to seal up splicing gaps between sidewalls of the holding cavity and peripheral edges of the fixing member, the welding blocks of the electrical terminals penetrating through the fixing member and the sealing tape to be exposed outside; wherein the sealing tape defines a plurality of through holes arranged side-by-side at one side thereof and corresponding to the welding blocks of the electrical terminals, the welding blocks pass through the through holes to project from under the sealing tape; and wherein a bottom face of a wall between every two adjacent terminal grooves of the base body is concaved upward to form at least one fixing hole, a top face of the fixing member protrudes upward to form a plurality of fixing columns corresponding to the fixing holes of the base body and fixed in the fixing holes of the base body.
