Patent ID: 8608516

Claim:
A waterproof electrical connector, comprising an insulating housing ( 21 ) and an electrical connector terminal ( 10 ), wherein the electrical connector terminal ( 10 ) being formed as a hollow tube and having axially aligned sections, the terminal comprises a contact section ( 11 ) and a connecting section ( 12 ) away from the contact section ( 11 ), the connecting section ( 12 ) being circumferentially provided with a plurality of axially extending resilient members ( 13 ), each resilient member ( 13 ) having a connected end ( 131 ) and a free end ( 132 ), wherein the connected end ( 131 ) is connected to the connecting section ( 12 ) and the free end ( 132 ) is deflected radially outward to form an opening ( 14 ) on the connecting section ( 12 ), wherein all of the plural resilient members ( 13 ) are engageable with the waterproof electrical connector, wherein the free ends ( 132 ) of the plural resilient members ( 13 ) form a circle (C), and said each resilient member ( 13 ) has a thickness T and a width W that satisfy the relationship of 1.5T W 6T, wherein an axial length L from the connected end ( 131 to the free end ( 132 ) of said each resilient member ( 13 ) is in direct proportion to the circumference of the circle (C) formed by the free ends ( 132 ), wherein the electrical connector terminal ( 10 ) is disposed in the insulating housing ( 21 ) and the insulating housing ( 21 ) has an inner hole ( 22 ) being 0.1 mm to 0.7 mm less in diameter than the circle (C) formed by the free ends ( 132 ) of the resilient members ( 13 ) of the electrical connector terminal ( 10 ) and a plurality of positioning grooves, and wherein when the electrical connector terminal is fully engaged with the electrical connector, the free ends press against the positioning grooves to lock the electrical terminal into the waterproof electrical connector.
