Description

“COIL ASSEMBLY WITH TERMINAL JOINT CONNECTION AND
PROCESS THEREOF”
FIELD OF THE INVENTION The present invention relates to a coil assembly with terminal joint connection and a process thereof. More particularly, the present invention relates to an assembling of coil assembly with terminal joint and terminals that extend parallel to coil winding and a process thereof to avoid wire looseness and breakage of wire during winding. BACKGROUND OF THE INVENTION
The bobbin supports and channels the winding and provides a termination and connection method. The bobbin is designed for use with a specific core shape. Bobbin termination is an important consideration because it is a connection element in a circuit. Bobbin with terminals improves production and facilitates the printed circuit board insertion. Bobbins are provided with terminals in which holes are provided for insertion of terminals after winding.
The assembly of bobbin is of careful consideration. Once the bobbin is wound, the winding leads need to be terminated. The wire leads need to be soldered to the terminals and care must be taken not to damage the bobbin with the heat of soldering process and the connections of terminals should not be loose.
US3701961A discloses an electrical terminal to be inserted into a flange of an electrical coil bobbin as a serrated mounting arm at one end, a U-shaped crimp portion at the other end and a laterally extending tab between the mounting arm and the crimp portion. The mounting arm is inserted into a hole in the bobbin flange, a wire from the coil is crimped to the terminal at the crimp portion, and the mounting arm is then bent towards the coil so that the tab extends parallel to the coil windings. The main drawback of the invention is that there is a risk of terminals being loose.
US3359520A discloses an encapsulated electrical coil which has its lead-in wires anchored to the bobbin of the coil by terminals secured to the bobbin by claws. The terminals are electrically connected to the coil on the bobbin by a dip soldering to legs integral with the terminals. The terminals are electrically connected to the lead-in wires by crimping the terminals about the lead-in wires. The main drawback of the invention is that clawing surface provides gripping to the terminals only in a longitudinal direction.
Therefore, there is a need to develop a coil assembly having bobbin with terminals in which holes are provided for insertion of terminals, prevents wire looseness and enabled to freeze in any direction or extend parallel to coil winding.
OBJECT OF THE INVENTION
The main object of the present invention is to develop a coil assembly with terminal joint connection and a process thereof to avoid wire looseness and breakage of wire during winding.
Another object of the present invention is to develop a coil assembly to freeze electrical connector orientation in any direction or extend parallel to coil winding.
Yet another object of the present invention is to develop a process to assemble a coil assembly by press fitting the terminals inside sealed bobbin of the coil and further joining it by methods such as but not limited to resistance welding.
Still another object of the present invention is to develop a coil assembly with a plurality of terminals to freeze electrical connector orientation in any direction without breakage and looseness of wire during winding.
SUMMARY OF THE INVENTION
The present invention provides a coil assembly with terminal joints and a process thereof to avoid wire looseness and breakage of wire during winding.
In a main embodiment, the present invention provides a coil assembly with terminal joints comprising a coil sub assembly having a bobbin, a coil, a bracket assembly having a U bracket and a mounting bracket, a plurality of terminals and a resistor. The plurality of terminals includes but not limited to terminals LH, LH’, RH, RTP. The coil is wounded around the bobbin sub assembly forming a coiled bobbin and around the U bracket that provides the magnetic field. The mounting bracket is crimpled with U bracket and with the coiled bobbin. The LH and RH terminals are press fitted inside the bobbin and the LH’ and RH’ terminals are press fitted into the bobbin and joined between terminal LH’ with terminal LH and terminal RH’ with terminal RH by methods such as but not limited to resistance welding, thus forming a complete design of coil assembly with terminal joints. The coil assembly with terminal joints prevents wire looseness or breakage of wire during winding and electrical orientation is frozen in any direction.
In another embodiment, the present invention provides a process to assemble a coil assembly with terminal joints comprising the steps of: (a) press fitting terminals LH and RH inside a sealed bobbin; (b) winding a coil and crimping a resistor around the LH and RH terminals of step (a); (c) press fitting the terminals LH’ and RH’ in bobbin after step (b) and further joining the terminals LH, RH, LH’ and RH’ by methods such as but not limited to resistance welding to form a coil assembly with terminal joints; and (d) crimpling the mounting bracket with U bracket and with the coiled bobbin after step (c).
