Abstract

An electrical connector includes: an elongated insulative housing having a bottom wall, a pair of side walls along a lengthwise direction, and an island located between the pair of side walls to form two longitudinal grooves; a row of contacts secured to each of the pair of side walls and exposed to a corresponding groove; and a shielding shell having a base secured to the insulative housing and a peripheral wall surrounding the pair of side walls to form an annular groove.

First claim

What is claimed is:

1. An electrical connector comprising:
an elongated insulative housing having a bottom wall, a pair of side walls along a lengthwise direction, and an island located between the pair of side walls to form two longitudinal grooves;
a plurality of contacts secured to each of the pair of side walls and exposed to a corresponding groove; and
a shielding shell having a base secured to the insulative housing and a peripheral wall surrounding the pair of side walls to form an annular groove; wherein
the base of the shielding shell comprises a horizontal bottom plate formed of two parts and an integral vertical shield plate extending along the lengthwise direction and interconnected between the two parts.

2. The electrical connector as claimed in claim 1 , wherein the two longitudinal grooves are connected with the annular groove.

3. The electrical connector as claimed in claim 1 , wherein the bottom plate is substantially coplanar with the bottom wall of the insulative housing.

4. The electrical connector as claimed in claim 1 , wherein the shield plate is secured to the island of the insulative housing.

5. The electrical connector as claimed in claim 1 , wherein the base of the shielding shell comprises a respective pair of engaging fingers located at each of two longitudinal ends of the shield plate and extending in opposite lateral directions.

6. The electrical connector as claimed in claim 1 , wherein the peripheral wall of the shielding shell comprises a pair of longitudinal side walls and a pair of lateral end walls, and each of the pair of lateral end walls is formed of two connected parts.

7. The electrical connector as claimed in claim 1 , wherein the shielding shell is formed of a unitary plate.

8. The electrical connector as claimed in claim 1 , wherein each of the plurality of contacts secured to each of the pair of side walls has a tail located inside the shielding shell and exposed to the annular groove.

9. The electrical connector as claimed in claim 8 , wherein the peripheral wall of the shielding shell comprises a pair of longitudinal side walls each having a plurality of inspection windows aligned with corresponding tails of associated contacts.

10. An electrical connector assembly comprising:
a first connector including:
an elongated insulative housing having a bottom wall, a pair of side walls along a lengthwise direction, and an island located between the pair of side walls to form two longitudinal grooves;

a plurality of contacts secured to each of the pair of side walls and exposed to a corresponding groove; and
a shielding shell having a base secured to the insulative housing and a peripheral wall surrounding the pair of side walls to form an annular groove; and

a complementary second connector including:
an elongated insulative housing having a bottom wall, a pair of side walls, and a pair of end walls, the pair of side walls and the pair of end walls together enclosing a mating groove, each of the pair of side walls having a pair of expanded portions at two opposite ends thereof to define a receiving space;
a plurality of contacts secured to each of the pair of side walls and exposed to both the mating groove and an associated receiving space; and
a shielding cover secured to the insulative housing and having a pair of side plates and a pair of end plates enclosing the pair of end walls and the two receiving spaces; wherein

when the first and second connectors are mated, the pair of end walls and the pair of expanded portions of each side wall of the second connector are received in the annular groove of the first connector, and the pair of side walls and the pair of end walls of the shielding cover engage an inner wall face of the peripheral wall of the shielding shell; and
the base of the shielding shell comprises a shield plate and a respective engaging finger located at each of two longitudinal ends of the shield plate, and the pair of side plates of the shielding cover comprises a pair of corresponding tongues for contacting corresponding engaging fingers.

11. The electrical connector assembly as claimed in claim 10 , wherein the shielding cover comprises a top wall from which the pair of side plates and the pair of end plates are bent.

12. The electrical connector assembly as claimed in claim 10 , wherein the shielding cover is formed of a unitary plate.

13. The electrical connector assembly as claimed in claim 10 , wherein each of the plurality of contacts secured to each of the pair of side walls of the second connector has a tail located inside the shielding cover and exposed to an associated receiving space.

14. The electrical connector assembly as claimed in claim 13 , wherein each of the pair of side plates of the shielding cover has a plurality of inspection openings aligned with corresponding tails of associated contacts.

15. An electrical connector comprising:
an elongated insulative housing having a bottom wall, a pair of side walls along a lengthwise direction, and an island located between the pair of side walls to form two longitudinal grooves;
a plurality of contacts secured to each of the pair of side walls and exposed to a corresponding groove; and
a shielding shell having a base secured to the insulative housing and a peripheral wall surrounding the pair of side walls to form an annular groove;
wherein the base of the shielding shell comprises a shield plate secured to the island of the insulative housing; and
wherein the base of the shielding shell comprises a respective pair of engaging fingers located at each of two longitudinal ends of the shield plate and extending in opposite lateral directions.
