ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an improved waterproof socket adapter design, especially a design which is able to provide a secure connection even if an eventual foreign force is present, and is shock resistant, waterproof has and electric leakage preventing functions.
BACKGROUND OF THE INVENTION
A conventional socket adapter design, as shown in
FIG. 1
, has two receptacles
111
at proper points within an insert holder
11
, and which are provided for copper tabs
21
at ends of a power cable
20
to a power source. The receptacles
111
are separated by a partition
112
. The insert holder
11
has pinholes
113
arranged on its front side and there are two passages provided for cords going behind them. The copper tabs
21
of the power cable
20
are placed in position in the insert holder
11
, while leaf copper conductors
33
are inserted in recesses
114
arranged in the insert holder
11
. Meanwhile, fuses
80
are placed in the receptacles
111
, then the insert holder assembly is inserted into the housing
12
to form a socket adapter. However, such a socket adapter design has some shortcomings, such as poor waterproof performance, owing to the fact that here are gaps between the insert holder
11
and the housing
12
and between the cover
13
and the housing
12
. Further, if joints
22
of the power cable
20
with the copper tabs
21
are in a poor condition, potential risks of removal of cord(s) and a short circuit will incur Furthermore, the cover
13
is not able to provide a positive waterproof performance. Because there is not any protection at the joints
22
of the power cable
20
, power failure or electrical leakage will be encountered due to cord removal or loosing after long periods of use or under an eventual foreign force. Therefore, it is really not an ideal design.
So, a socket adapter design which is able to provide a waterproof function, secure connection, shock resistance and high safety is needed.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an improved socket adapter design, especially a design which is able to provide a secure connection even in the presence of an eventual foreign force, and which is shock resistant, waterproof and has electrical leakage preventing functions.
However, in order to describe the object, characteristics and functions of the present invention in detail, an example of embodiment and relative figures to the present invention are given as follows:
