ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cable connector, and particularly to a cable connector having a cover unit including two similar portions attached together.
2. Description of Prior Art
A cable connector is used to mate with a complementary connector for transmitting signals between two electronic devices, such as between a computer and a printer. However, since the cable connector is positioned externally between devices, the cable connector may become loosened or damaged due to an external force exerted thereon.
Referring to
FIGS. 5 and 6
of the attached drawings, a cover unit
9
of a cable connector comprises top and bottom portions
91
,
92
. The bottom portion
92
has a pair of parallel side walls (not labeled) with a protrusion
921
formed on each inner surface thereof. The top portion
91
defines a slot
911
for engaging with the protrusion
921
to form the cover unit
9
. However, when an external force is exerted on one side wall of the cover unit
9
, the protrusion
921
is easily disengaged from the slot
911
and the top portion separates from the bottom portion
92
. Thus, the cable connector
9
is unreliable and easily damaged. Such a cable connector is disclosed in Taiwan Patent Application No. 81214651. Additionally, some prior arts taught to connect top and bottom portions of a cover unit of a cable connector by supersonic soldering, which increases production costs.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a cable connector having a cover unit including a top and bottom portions securely attached together for withstanding an external force exerted on a side wall of the cover.
In the preferred embodiment of the present invention, a cable connector comprises a main body, a shielding shell surrounding the main body, and a cover unit covering the shielding shell. The shielding shell defines a plurality of seating holes. The cover unit includes a top portion and a bottom portion attached together. The top portion forms a first and a second side walls on opposite sides thereof, the first side wall of the top portion defines a cutout and a protrusion. The bottom portion forms a first and a second side walls. The first side wall of the bottom portion forms an upwardly extending flange for insertion into the cutout of the first side wall of the top portion, and an upwardly extending latching tab defining an opening for engaging the protrusion of the top portion. The top and bottom portions form a plurality of seating columns for insertion into corresponding seating holes.
