ABSTRACT:

FIELD OF THE INVENTION
This invention relates to an improved connector electrical devices which transmit power driven signals, one that has a shield structure to prevent metallic leads from outside exposure and enhances connection strength.
BACKGROUND OF THE INVENTION
Conventional electrical devices usually have a connector for transmitting power driven signal with an external signal line. The connector usually includes a male and a female connector to make connection simple.
FIG. 1
illustrates a typical conventional connector now being widely used. It has a conductive male connector
1
and a female connector
2
. The female connector
2
includes a fastener
22
which has a bore
21
formed therein. Inside the bore
21
, there is a metallic barrel fastener
23
which connects to a conductive wire
24
. The male connector
1
may be plugged into the bore
21
to connect with the barrel fastener
23
for transmitting a signal through the wire
24
.
The conductive male connector
1
is naked and exposed to ambient environment. It is prone to produce short circuit when not being properly used. It may also be disconnected easily from the female connector
2
and may result in harmful accident to children when not being properly guarded.
With increasing number of electric devices and gadgets targeting children market nowadays, it becomes a pressing need to design a safer connector to lower the potential risk to users, particularly to children.
SUMMARY OF THE INVENTION
It is an object of this invention to provide an improved connector for power signal transmission use in electrical devices and to offer a higher adaptability and safety level to meet stricter safety specifications and requirements of future products.
The connector according to this invention has a shield around a naked male connector for engaging with a female connector so that short circuit accidents may be greatly reduced.
In one aspect of this invention, the shield sleeve structure includes a latching means for anchoring on the male connector and for freeing the male connector to move and engage with the female connector when in use.
In another aspect of this invention the male connector has a groove formed in a side wall to hold a resilient member therein. The shield sleeve has a stub extending in the groove and is movable by the resilient member in the groove. Hence the naked male connector may be protected by the shield sleeve from outside exposure all the time.
