Full Text Field of the Invention
The present invention relates to a battery terminal connector adapted to connect electric
wires to a terminal of a lead acid battery and more particularly to a simple structure of
battery terminal which is inexpensive to manufacture, easy to handle, less time
consuming, more durable and long lasting and can positively be secured to the terminal
of the battery.
Description of the related Art
Storage batteries of the type used in automobiles, generators and trucks and the like,
generally have two terminal posts made of a lead alloy material having truncated conical
shape to I.S. specification No.-7372-1995 & JIS(Japan), specification No:-D5301-1999.
To fasten the end(s) of wire(s) or cable(s) to battery terminals is a common practice. With
progress of engineering, various means, tools tackles and devices have been developed
to achieve the goal in such a way that needs minimum time and effort.
The battery is connected to the vehicle electrical system by a battery cable assembly. The
cable assembly has connectors which clamp to the battery posts, providing a secure
electrical and mechanical connection. A conventional connector for connecting cables to
the battery is a metallic molded, generally U-shaped device with a bolt passing through
outwardly projecting yoke-like arms for securely clamping the connector to the battery
post. The connector may also be a stamped metal battery terminal connector, fabricated
from sheet metal.
US57331S2 is directed to a battery connector which permits mechanical and electrical
connection to a battery terminal post. The connector of the patent no. US5733152 has
enhanced resistance to rotation when connected to a battery terminal post. This connector
is adaptable for automated assembly. It is also adaptable to different automobile models
and batteries.
US5879202 is also directed to a battery connector. This connector is of the type that
permits it to be tightened on the battery post that are positioned above rather than on the
side of the connector.
The known art for securing the end(s) of the wires and cables initially consisted in tying
or twisting the ends of the wire and cable strands to the terminals or connectors. With the
added requirement of tight clamping to terminals or connectors for proper current
conduction, lugs that were clamped or crimped to the end(s) of the wire(s) or cable(s) on
one end and securely clamped screwed or bolted to the terminal on the other end using
hand tools or power tools gained favor of usage. Additional relevant prior art references
include US6250973, US5941738, US5879202, US5800219, US5738552, US5711688,

US5672442, US5599210, US5316505 and US4354726. None of these patents, however
alone or in combination, disclose the present invention.
However, all above the known device for securing the ends of wires and cables
particularly for conducting electrical power, have major drawbacks.
Firstly, The process by using the clamping or de-clamping device which connect the ends
of wires and cables from the terrninal(s) was a time consuming and cumbersome so that
in condition where the end(s) of wire(s), cable(s) require to frequently clamped to and de-
clamped from the terminal and upkeep of the related system(s), these activities of proper
and repetitively tight clamping or de-clamping can not be carried out to the desired level
of satisfaction and frequency, which contributes to reduction of life of the related system.
Secondly, such clamping or de-clamping would almost always required the use of hand
or power tools like spanners, screw drives, pliers or any other standard or tailor-made
tools. In actual working conditions very often such tools are not readily available when
required. Also in areas and places where access is not easy, it is very difficult to perform
the clamping or de-clamping activity using such tools. The above reasons constitute a
considerable psychological deterrent to workers and operators to the activity of properly
clamping or de-clamping the cable(s), wire(s) or lead(s) using hand or power tools.
Thirdly, the lugs or end connection of the known art are almost always of an metal
construction, This exposes the workers or operator to the risk of sustaining injury from
heat or electrical shock, if, while clamping or de-clamping, he or she accidentally touches
the said exposed metal part, which might become too hot to touch, or carry electricity.
Consequently, clamping or de-clamping would necessarily have to be done under
conditions where the wire(s) or cable(s) are not carrying any electricity and are
sufficiently cold to touch.
Fourthly, In such clamping or de-clamping is done under current carrying or in live
condition, the process will be slow, and might result in considerable sparking between the
wire(s) or cable(s) end(s) which may be damaging to the related equipments) or
system(s).
The battery connector for car battery is now often used as U shaped brass clamp whish is
fitted with nuts and bolts. To clamp or to de-clamp the connector a crew driver and small
tools or wrench are needed. Apart from that, this clamping or de-clamping process is time
consuming as well as need human effort and technical know-how. Any other person who
has not enough physical strength cannot clamp or de-clamp by using ordinary tools. For
this reason it is seen that battery connectors often remains in connected position for years
which creates many difficulties which as follows:
a) Heavy oxides and sulphides are formed all over the battery connector which
causes poor conductivity at the point of contact in battery.
b) Under these heavy oxide condition the resistant at the point of contact is increased
which causes the heating of terminal during activation of self starter.
c) The long time connection corrodes the battery terminals.

d) The long time connection will reduce the life of the battery and after that this
battery will not be in used.
Hence an improved device for connecting the battery terminal is desired to overcome
the disadvantages of the related art.
Summary of the invention
Accordingly an object of the present invention is to provide a battery connector being
capable of establishing a reliable electrical connection for quick clamping and de-
clamping and providing protection against corrosion, low battery life and leading to
quick safe, easy and respectively proper clamping and de-clamping.

The other embodiment of the invention is to provide an improved connector device which
is more durable and has long life.
The main aims of this invention to provide an improved connector device which
comprises
a) A top cap( 1) is on the top of device,
b) A fly nut(2) which is cladded with polymer is just below the top cap which has to
rotate clockwise for proper clamping.
c) A cavity (3) made up of brass, the connector which goes through the conical lead
terminal of the battery
d) A brass jacket(4) is just inside the fly nut for tightening the connector.
e) A brass plug(5) which is a part of brass component that forms the cavity (3) lise
above the cavity.
f) A thread (6) which is an inclined plane for which advantage is taken to push the
cylinder(7) downwards.
g) Grips on side of the fly nut(2) to put force on the fly nut.
Characterized in that the force exerted by finger on the both ends of the fly nut(2)
produces a couple whose magnitude is 2 'K' x 'X' where in 'K' = force exerted by
finger, and X = distance between the two force.
The advantages and novel features of the invention will become more apparent from
the following detailed description when taken in conjugation with accompanying
drawings and these drawings are illustrative in explaining the constructional details of
the device of the invention. Such drawings are shown in 3 sheets.
The improved device of the present invention makes the use of a cantilever and
linkage mechanism to achieve repetitive clamping and de-clamping. The brass jacket

(4) and brass plug(5) are made of brass because of it is high current conductive
material. The cantilever leaf (7) are also made strong material that can be withstand
high temperature and sufficiently wear resistant for repeating clamping and de-
clamping.
The fly nut is cladded with suitable polymeric material (such as high density
polyethylene, polypropylene, Teflon, polyester or copolymers thereof.) that is
sufficiently strong, electrically and thermally insulated with resistant to high
temperature.
When the force exerted on both ends of the fly nut (2) it produces a couple. This
couple forms a heavy torque on the single start thread (6). The figure 1 is sectional
view of the battery connector of the present invention. In fig 1 the single start thread
(6) is an inclined plain. This thread is a screw. Since it is a screw, the cylinder (7) is
forced to move downwards for clamping. The cylinder (7) is hollow and it is leaf of
collapsing funnel. It acts a cantilever (7).
The one of the advantage and novel feature of the present invention is the funnel like
geometry of the collapsing cylinder (7) so that when collapsing force is applied at the
free end of the cantilever more effective and stronger grip will be on lead terminal of
the battery.
The one of the advantage and novel feature of the present invention is that the thread
(6) is an inclined plain that is screw. Since it is screw type, force is applied to move
the cylinder (7) downwards for clamping. One of the important point for this features
is that diameter of the inclined plain (6) and angle of the inclination of the screw
plain. (Number of thread/ cm). There is vertical movement of the cylinder.
All the aforesaid mechanical advantages have been combined ingeniously. As a result
the connector grips the battery post tightly.
This invention also relates to a process for clamping and de-clamping the battery
connector by using invented device.

This process comprises
a) the cavity of the connector (3) is to be pushed tightly through the conical lead
terminal.
b) The connector marked with positive mark (+) should be inserted in the positive
marked (+) lead terminal of the battery and the connector marked with negative
mark (-) should be inserted in the negative marked (-) lead terminal of the battery.
c) After fitting the connector on the battery terminals, the arm (8) of the fly nut (2)
of the connector has to rotate by hand in clockwise direction by giving gentle
downward pressure.
d) Tighten the fly nut (2) firmly.
e) To open the connector, the fly nut (2) has to rotate by hand in anticlockwise
direction.
Another point is that to clamp the end of the cable(s) to the end of the device the
screw number may be varied according the specific requirement. Further it also to
noted that the link and lever mechanism may be varied to achieve this goal.
The device of the invention finds particular use in batteries for automobile,
generators and such engines, machinery or equipment, which require frequent
clamping and de-clamping between the leads and terminals. For example, if any
such engine or machinery or equipment remains idle for a considerable lengths of
time, it is always advisable to disconnect the leads from the terminals to reduce
drainage of current that would otherwise reduce charges level of the battery to
such an extent that could either render the battery unusable or damage the related
equipment or system. Simultaneously, a similar device can be used on the ends of
a battery charger which then can be quickly connected to the battery terminals for
charging or recharging or trickle charging for maintenance of required charge
levels. The device being easily operated with one hand can be used in areas where
it is normally very difficult to work with tools.

The cover-cum-handle can be different, distinct colors and can have provisions
for carrying tags or ferrules for individual identification. This would greatly
reduce the risk of wrong connections which could otherwise lead to failures of the
related equipment(s) or system(s).
The fig.(2) shows the top cap made up of strong & rigid polymer. It is fitted over
the connecting wire to prevent exposure of the necked portion of the wire that
caries heavy current from the battery. The top cap is clamped with the brass nut
(5) by a bayonet catch as it is done in the holder of a electric bulb.
The following lines summarize the advantages of the improved device of this
invention over the prior art and technology:
a) The present device is able to achieve repetitive firm clamping and de-
clamping in quick and less human effort.
b) The device of this invention can be operated using one hand as well as by any
person, not necessary to know any technical knowledge.
c) The device of this invention is safe against accidental thermal or electrical
shocks to operator or worker.
d) The improved device can bear distinct identification by way of color
differentiation and numbering codes to avoid accidental wrong connection.
e) The improved device is helpful for periodical cleaning of the battery terminal.
f) This cleaning also increases the longevity of the battery.
g) The improved battery connector is more durable and has long life.
The connector of the present invention affords easy and convenient connection
and disconnection from the battery terminal through rotation. Along with the
remaining, described structure this construction prevents over torquing of the
connector. It is under stood that, given the above description of the embodiments
of the invention, various modifications may be made by one skilled in the art.
