FAST-CONTACT CLIP
Abstract
A clamping device for clipping against an electric wire so to
connect two wires together, the device comprising a pair of levers
which are connected pivotally free together along an intermediate
portion of the levers, one end of the levers forming a squeeze
handle and the opposite ends of the levers forming a pair of jaws,
one of which has a seat across which a wire may be rested and the
other jaw carrying a pointed stud for piercing the insulation
around the seated electric wire and electrically engaging the
enclosed electrical conductor.

Claims
What I now claim is:
1. In a fast-contact clip, the combination of a pair of levers of
generally channel cross-sectional configuration, said levers being
made of rigid plastic material so as to be electrically
nonconductive and being pivotally connected by means of a pin
extending through opposite sidewalls of said levers and bridging a
channel space therebetween, said pin pivotally connecting
longitudinally intermediate portions of said levers to form a pair
of handle members at one end of said levers and a pair of jaws at
the opposite ends of said levers, means including a tension coil
spring fitted around said pin, said spring having opposite ends
bearing against said levers to urge said jaws toward and into
engagement with each other, one of said jaws having a single,
electrically conductive metal stud secured thereto and extending
therefrom toward said other jaw, means for securing an electrical
conductor to said stud, said stud having a point at one end thereof
pointing toward said other jaw, said other jaw having an opening
therein to accommodate said stud upon engagement of said jaws and
having a transversely extending, groovelike seat formed therein to
support an insulated electric wire in alignment with said point of
said stud, said point of said stud penetrating the insulation of
said electric wire to electrically engage with an electric
conductor therein upon engagement of said jaws.
Description
This invention relates generally to clips. More specifically the
present invention relates to electric clips.
A principal object of the present invention is to provide a means
whereby two electric wires may be connected together
electrically.
Another object of the present invention is to provide a
fast-contact clip wherein the two wires may be connected together
without the necessity of taking the wires apart, thereby providing
a safe manner for making the electrical engagement without
endangering the operator by getting an electric shock.
Another object of the present invention is to provide a
fast-contact clip wherein accordingly the device permits making a
connection with a live electrical conductor without the danger of
the operator getting an electric shock.
Other objects of the present invention are to provide a
fast-contact clip which is simple in design, inexpensive to
manufacture, rugged in construction, easy to use and efficient in
operation.
These and other objects will be readily evident upon a study of the
following specification together with the accompanying drawing
wherein:
FIG. 1 is a side elevation view of a fast-contact clip shown with
the jaws in a closed position; and
FIG. 2 is an enlarged fragmentary view thereof shown partly in
cross section and showing the jaws in a separated position.
Referring now to the drawing in detail, the reference numeral 10
represents a fast-contact clip device, according to the present
invention, wherein there is an assembly comprised of a pair of
levers 11 and 12 each of which is made of rigid plastic material so
as to be electrically nonconductive. The levers 11 and 12 are
enjoined pivotally free together by a transverse extending pin 13
which connects the longitudinal intermediate portions of the levers
together. Each of the levers 11 and 12 are of generally
cross-sectional channel configurated across which the pin 13
extends, the pin 13 extending through an arbor or sleeve 14 fitted
between opposite sidewalls of the lever members, and a tension coil
spring 15 being fitted around the arbor 14, the opposite ends of
the tension coil spring 15 bearing against the two levers so as to
urge together a pair of jaws 16 and 17 formed at one end of the
levers.
The jaw 16 has a stud 18 extending therethrough which at one end
thereof is provided with a point 19. The stud 18 is made of
electrically conducted metal and is connected to an electric
conductor 20 which is attached at its end around the stud and
secured by means of a washer 21 and nut 22.
The other jaw 17 is provided with a transversely extending seat 23
and across which an electric wire 24 can be seated.
In operative use, the opposite ends 25 of the levers 11 and 12
together form a convenient handle that can be squeezed together so
as to separate the jaws apart as shown in FIG. 2 and after which
the electric wire 24 is placed across the seat 23. By releasing the
handle, the pointed end 19 of the stud 18 will now puncture the
insulation 26 of the electric wire 24, the point 19 electrically
engaging the conductor 27 contained within the wire 24, thus
establishing an electric connection to the conductor 20. It is to
be noted that a clearance opening 28 is provided in the jaw 17 so
that the point 19 of the stud 18 will clear the jaw 17. Thus the
point 19 will not become blunted after extensive use.
Thus there is provided a fast-contact clip that comprises a helpful
device in automotive maintenance as well as for other uses.
