Description

Technical Field

[0001] The utility model relates to the technical field of quartz watches, in particular to a quartz watch movement coil component. Background Art

[0002] Quartz watches are watches that are regulated by electronic oscillators, that is, quartz oscillators. Since they are powered by batteries, the watches are more accurate and have smaller errors, with monthly errors within plus or minus 15 seconds. Secondly, the process is simpler than that of mechanical watches. Generally speaking, a battery can keep a watch working normally for two or three years at most, and then the battery must be replaced. Normally, the life of a quartz watch is about ten years. When the quartz amplitude decreases, the time is no longer accurate, and it is necessary to debug and replace parts. The type of coil in the movement of a quartz watch belongs to the current coil: the current generates a driving force to drive a small motor. The coil is an inductor element. The quartz clock relies on the natural frequency of the quartz oscillation. The oscillating current flows back and forth between the inductor coil and the quartz. The current coil works with a current signal and is generally connected in series to the circuit. In order to reduce the impact on the circuit, while meeting the action requirements, it is hoped that its resistance is as small as possible to reduce the circuit voltage drop. When the coil is installed in the movement, welding is usually used.

[0003] The watch movement coil assembly disclosed in the existing patent announcement number CN216411874U includes a main plate, a metal pressing plate, a wire core assembly, a coil bracket and a PCB board. The wire core assembly mainly includes a wire rack, an enameled wire is wound around the outer side of the wire rack, and a plurality of openings are provided on the surface of the wire rack. A rotor assembly is installed between the main plate and the stator sheet. The coil bracket is fixedly connected to the surface of the wire rack, a positioning column is integrally formed on the surface of the coil bracket, and two winding columns are integrally formed on the surface of the coil bracket. The PCB board is installed on the main plate. Through the position structure design of the wire rack and the winding column, the fixed-point winding effect of the relevant enameled wire can be effectively achieved, so that it is more conducive to the staff to use special tools to perform welding operations between the corresponding enameled wire and the relevant PCB board, effectively preventing the wire ends of the enameled wire winding from being scattered, making the welding operation more convenient. Through the position structure design of the connecting frame, the protrusion, the metal pressing plate, the coil pressing block and the stator sheet, the restriction effect on the PCB board and the corresponding wire core assembly can be effectively achieved.

[0004] The above coil assembly can make the welding operation more convenient, but the winding convenience of the enameled wire and the fixing stability of the coil bracket still need to be further improved. In view of the above problems, a quartz watch movement coil assembly is proposed. Utility Model Content
