Abstract

An electrical connector (1) includes an insulative housing (2) and a plurality of terminals (3) received in the housing. The housing has a front end with an opening for receiving an end of the FPC in engagement with contacting portions of the terminals, and a back end with a plurality of T-shaped protrusions (202), and a side end with two latching arms (21). An actuator (4) is pivotably mounted relative to the housing for floating movement between a first position allowing free insertion of the FPC into the opening and a second position biasing the FPC against the terminals. A shielding (5) is engaged with the back end and two latching arms of the housing for protecting the connector from Electro Magnetic Interference (EMI) during transferring signals between the FPC and the PCB by the connector. The shielding can also reinforce the strength of the housing.

Claims

1. An electrical connector for electrically connecting a flexible substrate with a printed circuit board (PCB), the connector comprising:

an insulative housing defining a main body and two latching arms extending from two opposite ends of the main body, a plurality of protrusions formed on a back portion of the main body and arranged along a longitudinal direction;

a plurality of terminals received in the housing;

an actuator pivotably engaging with the housing; and

a shielding mounted on the housing, the shielding comprising a plate portion and a pair of clasping portions extending forwardly from two opposite sides of the plate portion, the plate portion defining a plurality of securing slots engaged with the protrusions of the housing;

the clasping portions engaged with the latching arms, wherein the plate portion defining a plurality of spaced indents on a front thereof and the clasping portion comprises a base portion, a clasper formed on the base portion opposite to the plate portion, and a strip clip extending from the base portion near the plate portion; and

the clasper extends and bends downwardly from a top edge of the base portion, and a cutout is defined downwardly in the clasper.

2. The electrical connector as claimed in claim 1, wherein the securing slots of the shielding and the protrusions of the housing have a substantially “

T”

shaped configuration.

3. The electrical connector as claimed in claim 2, wherein the protrusion is formed on a top surface of the housing.

4. The electrical connector as claimed in claim 1, wherein a pair of grounding tabs extends downwardly from a back longitudinal side of the plate portion.

5. The electrical connector as claimed in claim 1, wherein the actuator comprises a base portion, a pair of latch blocks formed outwardly on two opposite sides of the base, and a metal sheet longitudinally formed in the base portion, a pair of ears extending from the metal sheet, a locking protuberance formed on a middle portion of each of the ears and received in the cutout of the shielding.
