ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to an electrical connector which electrically connects a flexible printed circuit (FPC) with a complementary connector.
2. Description of Related Art
Taiwan Pat. Application Nos. 84218005, 85210257 and 88220830 each disclose a conventional electrical connector for a flexible printed circuit. Referring to
FIG. 5
, an earlier developed electrical connector, owned by the same assignee with the instant invention, for a flexible printed circuit comprises an insulative housing
6
, a shield
7
enclosing the insulative housing
6
, and a stuffer
8
. The shield
7
includes a top wall
71
, a bottom wall
72
opposite to the top wall
71
, and a pressing plate
74
which is positioned between and parallel to the walls
71
,
72
. The pressing plate
74
is connected with the bottom wall
72
via a pair of rectangular linkers
73
. The pressing plate
74
and top wall
71
define a first receiving slot
63
for receiving a flexible printed circuit (not shown). Similarly, the pressing plate
74
and the bottom wall
72
define a second receiving slot
64
for receiving the stuffer
8
. The stuffer
8
comprises an elongate flange
82
and a pair of cutouts
83
for receiving the linkers
73
. In manipulation, the flexible printed circuit is first inserted into the first receiving slot
63
. Subsequently, the stuffer
8
is further pressed forward into the second receiving slot
64
to press the pressing plate
74
upwardly via the flange
82
thereof, whereby the pressing plate
74
upwardly presses the inserted flexible printed circuit into electrical connection with terminals (not shown) of the electrical connector.
However, as shown in
FIG. 5
, after the stuffer
8
is rearwardly pulled out to disengage the inserted flexible printed circuit from the terminals, the stuffer
8
is loosely received in the second receiving slot
64
and may sway upwardly and downwardly. Such a sway is not only inconvenient for manipulation, which may cause damage or breakage of the stuffer
8
, but also inconvenient for packaging of the electrical connector.
Hence, an improved electrical connector for a flexible printed circuit is required to overcome the disadvantages of the conventional electrical connector.
SUMMARY OF THE INVENTION
Accordingly, one object of the present invention is to provide an electrical connector for a flexible printed circuit, which can prevent a stuffer thereof from swaying upwardly and downwardly.
In order to achieve the object set forth, an electrical connector for a flexible printed circuit in accordance with the present invention comprises an insulative housing, a plurality of terminals, a stuffer and a shield. The housing comprises a receiving slot for receiving the flexible printed circuit and a plurality of receiving passageways communicating with the receiving slot for receiving the terminals. The stuffer comprises an elongate body and an flange extending downwardly from a rear edge of the body. The body defines a pair of cutouts at the rear edge thereof. The shield enclosing the housing comprises a top wall, a bottom wall opposite to the top wall, a pressing plate positioned between and parallel to the top and bottom walls, and a pair of linkers for being received in the cutouts of the stuffer. The pressing plate and the top wall define a first receiving slot for receiving the flexible printed circuit. Similarly, the pressing plate and the bottom wall define a second receiving slot for receiving the stuffer. Each linker comprise a rectangular link plate connecting the pressing plate and the bottom wall, and a block plate extending laterally from a side edge of the link plate for supporting the body of the stuffer and for preventing the stuffer from swaying after the stuffer is pulled out from the housing.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
