DESC:FIELD OF THE INVENTION

[0001] The present disclosure relates to a motor-starter switch assembly. More particularly, the present disclosure relates to a retainer adapted to rest inside a housing of the motor-starter switch assembly.

BACKGROUND

[0002] A motor-starter switch assembly is a device that controls the starting and stopping of an electric motor. When the electric motor is started, the starter's contacts come together, allowing current to flow to the electric motor. When the electric motor is stopped, the contacts must separate to break the circuit and stop the electric motor. However, during this process, arcing or sparking can occur between the contacts due to the high electrical energy involved. Arcing or sparking can cause damage to the contacts, reducing the lifespan of the motor-starter switch assembly and increasing the risk of electrical fires. In addition, with the coming up of new technology, the new parts are to be accommodated within the motor-starter switch assembly to facilitate compact packaging and a stable configuration of the motor-starter switch assembly.

[0003] The currently available retainer may not fit well with certain types of motor-starter switch assemblies. Additionally, some retainer shields may not provide adequate protection against arcing, and sparking and may have relative movement of the parts within resulting in arching and sparking. Thus, it is desirable to develop an improved retainer device for the motor-starter switch assembly.

SUMMARY

[0004] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.

[0005] In an embodiment, a motor-starter switch assembly is disclosed. The motor-starter switch assembly includes a housing adapted to accommodate one or more components of the motor-starter switch assembly, and a retainer adapted to be positioned within the housing. The retainer includes a plate portion having a plurality of openings. The plurality openings are adapted to receive the one or more components of the motor-starter switch assembly. The retainer includes a plurality of walls extending orthogonally outwardly from a surface of the plate portion, and a plurality of lock mechanisms to enable the coupling of the retainer with the housing of the motor-starter switch assembly and facilitate the locking of the one or more components of the motor-starter switch assembly with the retainer. The plurality of walls is adapted to position of the one or more components of the motor-starter switch assembly.

[0006] In another embodiment, a retainer for a motor-starter switch assembly is disclosed. The retainer includes a plate portion having a plurality of openings wherein the plurality openings are adapted to receive the one or more components of the motor-starter switch assembly, a plurality of walls extending orthogonally outwardly from a surface of the plate portion. The plurality of walls is adapted to position of the one or more components of the motor-starter switch assembly. In addition, the retainer includes a plurality of lock mechanisms to enable the coupling of the retainer with the housing of the motor-starter switch assembly and facilitate the locking of the one or more components of the motor-starter switch assembly with the retainer.

[0007] The retainer provides a plurality of lock mechanisms having the snap-fit locking mechanism that is quick and easy to assemble as compared to other types of fastening systems. The proposed retainer does not require additional mechanical elements to facilitate the locking mechanism. In addition, the disassembly of the plurality of lock mechanisms having the snap-fit locking mechanism is also easy. Additionally, the retainer further provides a reliable and vibration-resistant connection.

[0008] Also, the proposed retainer provides protection against the arc or spark generated in the motor-starter switch assembly during the actuation of a moving contact bridge of the motor-starter switch assembly. In addition, the installation of the plurality of parts of the motor-starter switch assembly within the retainer constrains any relative movement of the parts thereby reducing any vibration and reducing any chances of short circuit and sparking. In this manner, the retainer makes the motor-starter switch assembly safe for operation and increases the operational life of the motor-starter switch assembly.

[0009] The retainer makes the motor-starter switch assembly safe for operation and increases the operational life of the motor-starter switch assembly. The retainer is used to protect the moving contacts of the motor-starter switch assembly. The retainer holds the moving contacts in place and prevents them from bouncing or vibrating. The retainer further covers the moving contacts and helps to contain any sparks or debris that may be generated during the switching process. Further, the retainer reduces the damage caused by arcing and increases the lifespan of motor-starters switch assembly.
