Description

Integrated sealing contactor Technical Field

[0001] This invention relates to an integrated sealing contactor, particularly to one used in elevator control systems. [I] Body-type sealing contactor. Prior Technology

[0002] Sealing contactors are commonly used in elevator control systems. They are electromagnetic switching elements used to control the start, stop, or power switching of elevator motors and can frequently open and close high-current circuits.

[0003] To ensure structural strength and compliance with electrical safety requirements, existing sealed contactors typically employ conservative designs for housing size and lower cover thickness, resulting in a larger overall size that hinders miniaturization. Furthermore, the lower cover is usually made of plastic injection molding, which, when the structure is thick, not only increases material usage but also requires a longer cooling time. Uneven cooling can also lead to warping or deformation, thus affecting product quality and manufacturing yield.

[0004] For the reasons mentioned above, how to achieve miniaturization and improve injection molding quality of the sealing contactor while maintaining structural strength and functionality is a pressing issue that related industries need to address. In view of this, the creator has actively researched and, with years of experience in related product development, and through continuous experimentation and improvement, has finally developed this invention. Summary of the Invention

[0005] The main purpose of this invention is to provide an integrated sealing contactor that reduces the overall proportion through structural configuration improvements to achieve miniaturization and high-density installation. Furthermore, by using a thinner design for the lower cover, the material thickness and cooling time during injection molding are reduced while maintaining structural strength and assembly functionality, thereby reducing molding warpage or deformation. This, in turn, reduces manufacturing costs and improves product quality and molding stability.

[0006] To achieve the above objectives, this invention provides an integrated sealing contactor, comprising a base, a lower cover disposed on the base, and an upper cover disposed on the lower cover. A release linkage is disposed inside the lower cover. A plurality of normally closed contacts and a plurality of normally open contacts are respectively arranged adjacent to each other on both sides of the release linkage. A bent plate connects the normally closed contacts and normally open contacts on one side. An electromagnetic drive unit is installed inside the base and located below the release linkage. The electromagnetic drive unit includes an iron core and a coil. The lower cover is a plastic injection-molded component with a thinner structural thickness compared to conventional sealing contactors, allowing for miniaturization of the contactor and shortening the injection molding cooling time to reduce warping deformation.

However, the accompanying drawings are for reference and illustration purposes only and are not intended to impose any restrictions on this work. Simple Explanation of the Diagram

[Figure 3] is a perspective view of the integrated sealing contactor of this invention, omitting the lower and upper covers.

[0009] Please refer to Figures 1 to 4. This invention relates to an integrated sealing contactor, comprising a base 10, a lower cover 11 on the base 10, and an upper cover 12 on the lower cover 11. A tripping linkage 13 is disposed inside the lower cover 11. A plurality of normally closed contacts 14 and a plurality of normally open contacts 15 are respectively disposed on both sides of the tripping linkage 13. The normally closed contacts 14 and normally open contacts 15 are arranged adjacent to each other vertically and correspondingly. A bent plate 16 connects one side of the normally closed contacts 14 and normally open contacts 15. An electromagnetic drive unit is installed inside the base 10. The electromagnetic drive unit includes an iron core 17 and a coil 18 and is located below the tripping linkage 13. When the coil 18 is energized, it drives the tripping linkage 13 to actuate, switching the normally closed contacts 14 and normally open contacts 15.

[0010] The lower cover 11 is made of plastic material by injection molding. Its structural thickness is optimized to reduce the thickness of the lower cover 11. While meeting the support and fixing functions, the lower cover 11 is thinner than the lower cover of the conventional sealing contactor. This shortens the flow distance and cooling time of the molten plastic during injection molding and reduces warping or deformation caused by uneven cooling.

[0011] With the above structural configuration, this integrated sealing contactor achieves miniaturization and high-density installation by reducing the overall proportions, and reduces the thickness of the lower cover 11, making the lower cover 11 less prone to deformation or warping during plastic injection molding, effectively shortening the molding cooling time and improving production efficiency, thereby reducing manufacturing costs and improving product quality and molding stability.

[0012] Although the invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Anyone skilled in the art may make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the invention shall be determined by the appended claims.
