ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a connector with a function of getting rid of surges, particularly to one possible to let surges to be flow to a metal connecting head and then to the ground to disappear.
A conventional connector shown in
FIG. 1
includes a fixing base
2
having a connecting head
3
, two symmetrical insulating members
4
fitted in the connecting head
3
, and an elastic clasp
5
contained in the two insulating members
4
for catching hold of a cable
1
. Then a guide wire of the cable
1
is inserted through a through hole
6
of one of the insulating member
4
to be caught in the elastic clasp
6
.
However, as the two insulating members
4
are located between the metal connecting head
3
and the elastic clasp
5
, if the cable
1
should receive a surge or a thunderbolt, the surge could not flow to the fixing base
2
to be led to the ground to disappear. Then electric or electronic appliances connected to the conventional connector might be damaged by the surge.
SUMMARY OF THE INVENTION
This Invention has been devised to offer a connector with a function of getting rid of surge. The connector is provided with an emitting piece and a connecting head in which the emitting piece is contained. Then a gap is formed between an upper end of the emitting piece and an inner surface of the connecting head so that a surge may flow through the gap to the metal connecting head and then to the ground to disappear.
