PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention and the manner in which it is to be performed.

Field of Invention:
This invention relates to the field of mechanical engineering.
Particularly, this invention relates to a cable termination mechanism.
Background of the Invention:
In electrical assemblies, motors and electrical parts are commonly used. Performances of such electrical devices depend on their make and construction and the manner in which they handle faults. Further, these assemblies need to be robust in their working configuration.
There are certain accessories which are typically required for motors with circuits. These accessories include Resistance Temperature Detectors (RTD) and Bearing temperature Detectors (BTD). Typically, an RTD is used to measure winding temperatures. Typically, a BTD is used to measure the bearing temperature rise.
A Terminal Box is an electrical equipment which encloses leads from the piece of electrical device that the Terminal Box is connected to the main power supply,
Typically, there are terminal Boxes suitable for both Copper and Aluminum cables. Ideal specifications of a Terminal Box size should make it sufficiently capable for easy termination and maintenance of cable.

Currently, the Terminal Boxes used in the industry include a plurality of cable/lead endings, typically laid out in a vertical or horizontal array form. These are secured by means of a screw fit or a nut-bolt fitting assembly. This provides a rigid fit. However, the rigidity brings in wear and tear because of lack of freedom of motion. Another drawback of the prior art is that cluring transportation damages occur like losing screws or breaking of electrical wirs.
There is a need for an improved cable termination mechanism.
Objects of the Invention:
An object of the invention is to provide a cable termination mechanism with increased freedom of motion.
Another object of the invention is to provide a Terminal Box for control cables with an improved cable termination mechanism, without compromising on its performance.
Yet another object of the invention is to provide a table termination mechanism which does not cause wear and tear of the cables which it terminates. Still another object of the invention is to provide a table termination mechanism with an easy maintenance capability.
Summary of the Invention:
According to this invention, there is provided a cable termination mechanism adapted to terminate cable, said mechanism comprises;

a. first ball and socket mechanism with a first ball adapted to receive a first
cable for termination and further adapted to move within a first socket
thereby providing freedom of movement for said terminated cable;
b. second batf and socket mechanism with a second ball adapted to receive a
second cable for termination and further adapted to move within a second
socket thereby providing freedom of movement for said terminated cable;
and
c. box adapted to enclose said first ball and socket mechanism, said second ball
and socket mechanism, and said connector means.
TypicalJy, said first ba]] and socket mechanism is linearly spaced apart from said ball and socket mechanism in the horizontal plane.
Additionally, said first ball and socket mechanism includes a first additional restraining means with respect to said first ball and said first socket in order to make or break the connection in correlation with placement of said first ball within said first socket.
Additionally, said second ball and socket mechanism includes a second additional restraining means with respect to said second ball and said second socket in order to make or break the connection in correlation with placement of said second ball within said second socket.

According to another aspect of this invention, there is provided a cable termination box comprising a plurality of said cable termination mechanism stacked one above another to terminate a plurality of cables.
Brief Description of the Accompanying Drawings:
Figure 1 illustrates a front view of the cable termination mechanism for a Terminal Box, according to the prior art.
The invention will now be disclosed in relation to the accompanying drawings, in which:
Figure 2 illustrates a detail view of arrangement of each termination mechanism; and
Figure 3 illustrates a front view of the termination box having an array of cable termination mechanisms.
Detailed Description of the Accompanying Drawing:
Figure 1, of the accompanying drawings, illustrates a front view of the cable termination mechanism for a Terminal Box, according to the prior art.
This illustrates the Terminal Box adapted to receive cables which are fixed by screws or nut-bolt mechanism as shown by reference numeral 10 in the accompanying drawing. A plurality of such termination mechanisms (Dll, D12,

D13, N11, N12, N13, D21, D22, D23, N21, N22, N23, SPARE) are put together to form a termination box (12). The termination mechanisms are slidable on an assembly rail (14).
Figure 2 illustrates a detail view of arrangement of each termination mechanism, according to this invention; and
Figure 3 illustrates a front view of the termination box having an array of cable termination mechanisms, according to this invention.
According to this invention, there is provided a cable termination mechanism, for a Terminal Box (40), adapted to provide an increased freedom of movement, for the cables (30), even when they are terminated, so as to eliminate shocks and wear and tear when said Terminal Box may be moved or displayed or tampered with.
In accordance with an embodiment of this invention, there is provided a termination mechanism (20) adapted to be applicable even in hazardous electrical device assemblies such as motors. Typically, this termination mechanism includes a first ball and socket mechanism (50). A first socket may be fixed on to the Terminal Box. A first ball which fits into said first socket is adapted to receive a first set of cables (30) which are to be terminated. The first ball is adapted to be fitted into said first socket such that it provides for a degree of freedom and some play, thus eliminating rigidity. The first ball and socket fixture ensures that a push-pull structure is established. Reference numeral 60 refers to termination mechanism from a first side i.e. the manufacturer or wiring side.
In accordance with another embodiment of this invention, there is provided a second ball and socket mechanism (80) complementary to each first ball and

socket mechanism, to form a complementary pair. Typically, a second set of cables / wires (90) i.e. user side wires / cables are terminated in said second ball and socket mechanism. Reference numeral 70 refers to termination mechanism a second side i.e. the user side,
In accordance with yet another embodiment of this invention, there is provided a connector means (110) adapted to connect said terminated first set of cables to said terminated second set of cables through respective ball and socket joints.
In accordance with still another embodiment of this invention, there is provided a box (130) adapted to enclose said first ball and socket mechanism, said second ball and socket mechanism, and said connector.
In accordance with an alternate mechanism of this invention, the push-pull structure of the ball and socket joint can be adapted to provide a make and break arrangement such that the movement of the ball inside the socket, towards the interior surfaces of the socket, may be controlled by an additional restraining means so as to make or break the connection.
This type of arrangement also eliminates crimping of wires because of the free play.
A plurality of such termination mechanisms (D11, D12, D13, N11, N12, N13, D21, D22, D23, N21, N22, N23, SPARE), in accordance with this invention, are put together to form a termination box (120).
