Description

A SYSTEM AND METHOD FOR ESTABLISHING SOLDERLESS CONNECTION BETWEEN ELECTRICAL AND ELECTRONIC CIRCUITS
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This patent application claims the priority of the Indian Provisional Patent Application filed on December 09, 2016 with the number 201641042175 and titled, "SYSTEM FOR ENABLING SOLDERLESS CONNECTION BETWEEN ELECTRICAL AND ELECTRONIC CIRCUITS", the contents of which are incorporated herein by the way of reference.
BACKGROUND
Technical Field
[0002] The embodiments herein are generally related to electrical and electronic circuits. The embodiments herein are particularly related to a system and method for establishing solderless connection between electrical and electronic circuits or circuit elements. The embodiments herein are more particularly related to a system and method for establishing solderless connection between electrical and electronic circuits or circuit elements through a complementary mechanical coupling thereby providing/achieving mechanical stability to solderless electrical connections and allowing connection of components in a correct and appropriate manner and preventing wrong connection in a solderless connection between electrical and electronic circuits.
Description of the Related Art
[0003] Electrical and electronic circuits are an integral part of technological advancements. A plurality of modules and sub-modules in an electrical or electronic circuits are configured to perform/execute a plurality of designed functions/tasks. There is a vital need to provide a continuous connection between the plurality of modules and sub-modules in the electrical or electronic circuits in a device for ensuring a continued working of a device. With the reducing sizes of electronic circuit elements and their increased usage, most of the printed circuit boards are produced in mass and are used in finished products directly.
[0004] However, soldering is continue to be one of the most preferred way of connecting the electrical circuits together. The soldering offers the advantage of a simple way of connecting two circuits through an application of heat, and offers a mechanically sturdy and stable connection. However, there are certain drawbacks associated with the soldering process as well. An extended application of heat on the circuit causes a failure of components in the circuit. The mechanical stability of the circuit is also dependant on the electrical connection between the circuit components, thereby sometimes resulting in a mechanical failure of the circuit connection. Soldering also does not prevent or avoid any wrong circuit connections. Further it is also not easy to dismantle and change a circuit configuration once the circuit components are soldered in a given configuration. There are temporary solutions like breadboard or terminal clips to form circuit connections for testing and evaluation purposes. However, these connection methods do not offer any mechanical stability and they are also not portable. Further they are cumbersome to use.
[0005] With the increased use of electronic development platforms, a need for the modular circuits that are connected to development platforms via electrical connectors is significantly increased. However these connectors do not offer any mechanical strength to the connection. Even with a small amount of movement or vibration, noise is easily introduced in an electrical connection. When a plurality of circuit elements are connected in a modular way, the complexity of electrical connection is increased and the possibilities of wrong circuit connections, resulting in damage to the circuit or danger to the user, are also prevalent. [0006] Hence, there is a need for a system and method to provide or achieve sturdy, portable and yet temporary connection between two or more electrical and/or electronic circuits. There is also a need to provide a system and method to provide a mechanically stable circuit connection, without depending on a mechanical strength of the electrical connection. There is further a need to provide a system and method for ensuring only correct and proper way of connecting two circuits and avoiding a wrong electrical circuit connection between the components.
[0007] The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
