ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a connector, and especially to a connector which is connected to the computer peripheral devices or other related products.
BACKGROUND OF THE INVENTION
Referring to
FIG. 1
, a prior art connector is illustrated. The connector includes a plug
10
. The plug
10
can be inserted into a computer peripheral device (such as modem, mouse, etc.) (not shown). A plurality of connecting terminals
101
are formed in the plug
10
. The connecting terminals
101
can be connected to a circuit board or the related circuit board (not shown). The plug
10
is screwedly connected to a metal plate
12
by using screws
11
. One end of the plug
10
is connected to a protecting cover
13
. The cover
13
may avoid the deformation of the connecting terminal
101
. The cover
13
can support the plug
10
.
Since the connecting terminal
101
can be inserted into a circuit board of a computer or other related circuit board. The circuit board can be inserted to a power source. In order that the computer peripheral device is not affected by electrostatic charges and to provide a steady message, the metal plate
12
of above structure is made of zinc alloy with a preferred hardness so as to generate a conduction effect. The electrostatic charges are lead out by the metal plate
12
so as to have a ground effect.
However, since the metal plate
12
of the zinc alloy has a preferred hardness and thus it is hard to be shaped and thus the assembly work is hard. Furthermore, the assembly cost is high. Furthermore, since the zinc alloy is expensive and thus the assembly cost is high.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a connector which is connected to the computer peripheral devices or other related products. The outer cover plate is made of plastic injection so as to reduce cost. A conduction effect is formed by the first metal plate and second metal plates so that the electrostatic charges in the circuit board can be lead out effectively for replacing the prior art zinc alloy product which has a preferred hardness and can be shaped, and is more expensive than the plastic frame. Since the cost of zinc is high so as to increase the whole cost of a computer in assembly.
To achieve the objects, the present invention provides a connector including a first plug, a second plug and a connecting casing. The first plug and second plug are installed with a plurality of terminals. each side of the first plug and second plug can be inserted with a computer peripheral device (such as a mouse, or a modem). The first plug and second plug are firmly secured to the connecting casing. The connecting casing is integrally made of plastic injection. A plurality of metal plates are installed on the connecting casing. The metal plate on the connecting casing has effect of conduction so that the electrostatic charges on a circuit board can be lead out effectively to provide steady message to the computer peripheral devices. Therefore, the cost is reduced and can be mass-produced. The plurality of metal plates are formed with two holding portions for buckling a circuit board.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
