Abstract

An electrical connector comprises an insulative housing (1), a contact set (2) assembled into the housing, a shield (3) enclosing the housing, and a pair of latch devices (4) assembled to the housing. The housing comprises a base portion (11), a plurality of passageways (111) defined in the base portion, a pair of retention portions (14) at a pair of ends thereof. The contact set comprises an insulative insert (21), a plurality of signal and grounding contacts (22) received in the insert, and a grounding bar (23) assembled in the insert. The signal and grounding contacts extend into the passageways. The pair of latch devices is assembled to the retention portions and each latch device comprises a latch portion (414) extending through a passageway (148) defined in a guide posts (145) of the housing. Each latch device has a tab (419) engaging with the housing.

Claims

1. An electrical connector, comprising:

an elongate insulative housing having a base portion, a plurality of passageways defined in the base portion, a pair of retention portions at a pair of lateral ends of the base portion;

a contact set assembled to a rear end of the housing and comprising an insulative insert, a plurality of signal and grounding contacts received in the insert, and a grounding bar assembled in the insert, the signal and grounding contacts extending into the passageways of the housing, the grounding bar having a plurality of grounding fingers electrically connecting the grounding contacts;

a grounding plate having a plurality of grounding fingers and at least one grounding beam, said at least one grounding beam electrically contacting the grounding bar of the contact set; and

a pair of latch devices pivotably mounted to the retention portions of the housing, each latch device having a latch portion for latching with a complementary connector and a tab engaging with the housing for resisting a pulling force acting on the each latch device from the complementary connector;

wherein

the each latch device has a body portion enclosing a corresponding retention portion of the housing and pivotably mounted thereon, and the latch portion extends forwardly from the body portion,

further comprising a shield enclosing the housing;

wherein

the shield has a pair of side portions formed on a pair of lateral ends thereof, and the each latch device has a spring tab extending from the body portion and abutting against a corresponding side portion of the shield;

wherein

each retention portion defies a guiding post extending forwardly therefrom, the guiding post forms an upright wall defining a passageway therein, the latch portion of the each latch device extending through a corresponding passageway.

2. The electrical connector as described in claim 1, wherein the body portion comprises an upper plate, a bottom plate, and a side plate connecting an edge of the upper plate and an edge of the bottom plate.

3. The electrical connector as described in claim 2, wherein the spring tab extends from the side plate of the body portion.

4. The electrical connector as described in claim 2, wherein the latch portion extends forwardly from the upper plate of the body portion.

5. The electrical connector as described in claim 2, wherein the tab is defined on the side plate of the body portion.

6. The electrical connector as described in claim 3, wherein the housing defines a pair of gaps in a rear end thereof, each gap is located between the base portion and a corresponding retention portion, and the spring tabs are received in the gaps.

7. The electrical connector as described in claim 6, wherein each retention portion integrally forms a retention post projecting from bottom face thereof, and the bottom plates of the body portions of the latch devices pivotably engage with the retention posts.

8. The electrical connector as described in claim 7, wherein the retention posts each have a bottom face with a laterally inclining portion.

9. An electrical connector comprising:

an insulative housing forming a pair of retention portions at lateral ends thereof,

each retention portion having a guiding post at a front end thereof, the guiding post defining a passageway therein;

a contact set received in the insulative housing, comprising;

an insert;

a plurality of signal and grounding contacts received in the inserts, each contact having a mating portion extending in the insulative housing; and

a grounding bar received in the insert and in electrically connection with the grounding contacts; and

a pair of latch devices pivotably mounted to the retention portions of the housing, respectively, each latch device having a latch portion at a front end thereof, the latch portion extending through the passageway of the each guiding post adapted for latching with a complementary connector wherein

the retention portions integral form retention posts, and the latch devices are pivotably mounted to retention posts;

wherein

the latch devices each forms a tab having a front end engaging with the insulative housing adapted for resisting a pulling force acting on the latch devices from the complementary connector;

further comprising a grounding plate electrically connecting with grounding bar.

10. The electrical connector as described in claim 9, further comprising a shield enclosing the insulative housing.
