Electrical connector having an insulative outer cover and a sealing member secured to the outer cover via a dovetail structure
An electrical connector includes: a contact module including an insulative housing and an upper and lower rows of contacts, the insulative housing having a base and a tongue, the upper and lower rows of contacts being exposed respectively to an upper and lower surfaces of the tongue; a shielding shell enclosing the contact module; an insulative outer cover enclosing the shielding shell, the outer cover having plural peripheral grooves at a front end thereof; and a sealing member having plural protrusions secured to corresponding grooves.
1. An electrical connector comprising:
a contact module including an insulative housing and an upper and lower rows of contacts, the insulative housing having a base and a tongue, the upper and lower rows of contacts being exposed respectively to an upper and lower surfaces of the tongue;
a shielding sub-assembly enclosing the contact module and forming an annular recess located around a front end region thereof between opposite front stop and rear stop thereof in a front-to-back direction;
a plurality of peripheral grooves and a plurality of dividers alternately formed in and along the annular recess; and
a sealing member having a plurality of protrusions snugly received within the plurality of grooves; wherein
the grooves are hidden behind the front stop in the front-to-back direction; and
the sealing member extends forwardly beyond the front stop of the shielding sub-assembly.
2. The electrical connector as claimed in claim 1 , wherein said shielding sub-assembly includes an insulative outer cover in which said annular recess is formed.
3. The electrical connector as claimed in claim 2 , wherein said shielding sub-assembly further includes a metallic shielding shell sandwiched between the contact module and the outer cover.
4. The electrical connector as claimed in claim 3 , wherein each of said grooves forms a trapezoidal cross-section taken along a vertical plane perpendicular to the front-to-back direction.
5. The electrical connector as claimed in claim 3 , wherein the recess forms a trapezoidal cross-section taken along a vertical plane perpendicular to a transverse direction which is perpendicular to the front-to-back direction.
6. The electrical connector as claimed in claim 1 , wherein said sealing member has a plurality of channels alternately arranged with the protrusions and receiving the corresponding dividers, respectively.
7. The electrical connector as claimed in claim 1 , wherein a depth of the annular recess is same with a depth of the grooves, and the dividers are coplanar with the front stop.
8. The electrical connector as claimed in claim 7 , wherein the rear stop is higher than the front stop in a vertical direction perpendicular to said front-to-back direction.
