Abstract

A waterproof and interference proof receptacle connector has an upper insulative housing, a lower insulative housing, a first terminal set, a second terminal set, a shell, a watertight casing and an interference proof rear guard. The first and second terminal sets are mounted respectively on the upper and lower insulative housings. The shell is mounted on the upper and lower insulative housings. The watertight casing is mounted around the shell. The interference proof guard is mounted on the watertight casing. The watertight casing provides a waterproof function to allow the waterproof and interference proof receptacle connector to operate in humid or underwater environment.

Dependent claims

A receptacle connector comprising:

an upper insulative housing;
a lower insulative housing mounted on a bottom of the upper insulative housing;
a first terminal set and a second terminal set substantially pointing symmetrical to each other;
the first terminal set mounted on the upper insulative housing and having multiple first terminals, each first terminal having
a first mounting section mounted on the insulative housing;
a first electrical contacting section formed on and protruding forward from the first mounting section;
and
a first soldering section formed on and protruding backward from the first mounting section;
the second terminal set mounted on the lower insulative housing and having multiple second terminals, each second terminal having
a second mounting section mounted on the lower insulative housing;
a second electrical contacting section formed on and protruding forward from the second mounting section;
and
a second soldering section formed on and protruding backward from the second mounting section;
a shell mounted on the upper insulative housing and the lower insulative housing and having
a cavity defined through the shell and accommodating the upper insulative housing, the lower insulative housing, the first terminal set and the second terminal set;
and
an extension tab formed on and protruding backward from a rear end of the shell;
a watertight casing mounted around the shell and having
a mounting hole defined through the watertight casing and accommodating the shell;
and
a fitting member mounted on the extension tab of the shell, wherein the fitting member is inverted U-shaped and has two opposite side surfaces;
and
an interference proof rear guard mounted in the fitting member of the watertight casing and having
a fitting tab;
a shielding guard tab formed on and protruding downward from the fitting tab;
and
two wings formed on and protruding forward respectively from two side ends of the shielding guard tab;
wherein a rear end of the upper insulative housing, a rear end of the lower insulative housing, the fitting member of the watertight casing and the shielding guard tab of the interference proof rear guard collaborate to form a glue space to receive watertight glue.
