Abstract

An electrical connector having an insulative housing having a mating cavity and a plurality of passageways, a plurality of electrical contacts received in the corresponding passageways and a sealing member received in the mating cavity. The insulative housing defines a front face and a mounting wall, the mating cavity is formed between the front face and the mounting wall. Each electrical contact has a contacting portion, a tail portion, and a main portion connecting the contacting portion with the tail portion, each main portion defines a plurality of barbs on both sides thereof. The sealing member has a base portion and at least one opening defined in the base portion for tail portions passing through. At least one electrical contact defines a wing on one side thereof, and the sealing member is restricted between the wing and the mounting wall.

First claim

The invention claimed is:

1. An electrical connector for mounting to a printed circuit board and mating with a complementary connector, comprising:
an insulative housing defines a front face for mating with the complementary connector and a mounting wall opposite to the front face, a mating cavity formed between the front face and the mounting wall for accommodating the complementary connector, a plurality of passageways penetrating through the mounting wall along a mating direction;
a plurality of electrical contacts received in the corresponding passageways, and each electrical contact comprising a contacting portion for electrically connected with the complementary connector, a tail portion electrically connected with the printed circuit board, and a main portion connecting the contacting portion with the tail portion, each main portion defining a plurality of barbs on both sides thereof for interferentially engaging with the corresponding passageway; and
a sealing member received in the mating cavity, and having a base portion and at least one opening defined in the base portion for tail portions of electrical contacts passing through; wherein
at least one electrical contact defines a wing on one side thereof, and the sealing member is restricted between the wing and the mounting wall.

2. The electrical connector as claimed in claim 1 , wherein at least two contacts on both sides define the wing on the main portion thereof, and the main portion having the wing has a larger width than the corresponding passageway.

3. The electrical connector as claimed in claim 1 , wherein the wing is in front of the corresponding barbs.

4. The electrical connector as claimed in claim 1 , wherein the sealing member defines a plurality of tabs on both of a top edge and a bottom edge, the insulative housing comprises a top wall, a bottom wall, a left side wall and a right side wall connecting the top wall with the bottom wall to form the mating cavity, a plurality of limiting slots are disposed in a conjunction area between the mounting wall and the top wall, and a conjunction area between the mounting wall and the bottom wall, for receiving the corresponding tabs.

5. The electrical connector as claimed in claim 4 , wherein each of the left side wall and the right side wall defines an ear portion on an outer surface thereof, for installing the electrical connector on the printed circuit board, and the two ear portions are disposed diagonally on both sides of the insulative housing.

6. The electrical connector as claimed in claim 5 , wherein each ear portion defines a through hole extending along a height direction.

7. The electrical connector as claimed in claim 1 , wherein the mounting wall defines at least one rib extending forwards into the mating cavity, and the passageways are defined in the rib, and the base portion is surrounding and abutting against the rib.

8. The electrical connector as claimed in claim 7 , wherein the base portion defines a plurality of openings and a plurality of spacing portions, and each spacing portions is defined between the two neighboring openings, the mounting wall has a plurality of ribs, and each spacing portion is restricted by two neighboring ribs and clamped between the wing and the mounting wall.

9. The electrical connector as claimed in claim 7 , wherein the base portion defines a pair of locking portions extending towards each other to match with the wing, and each locking portion is thinner than the base portion, the locking portions are positioned between the wing and the mounting wall.

10. The electrical connector as claimed in claim 7 , wherein a pair of T-shaped slits are defined on both sides of the rib, and the slits are located between two rows of the passageways along a height direction.

11. The electrical connector as claimed in claim 10 , further comprising a pair of stop blocks for limiting the sealing member, wherein each stop block is of T-shaped, defines a strip shaped body and an extension portion extending rearwards from the middle of body.

12. The electrical connector as claimed in claim 11 , wherein the stop blocks are received in the corresponding slits, and one end of each body is abutting against the neighboring locking portion.

13. The electrical connector as claimed in claim 8 , wherein the passageways are divided into two rows along a height direction of the insulative housing, the ribs are aligned with the corresponding passageway, and each rib is divided into three segments by two relative passageways along the height direction.
