本考案は、時計用モータのステータにて回路基
板を兼用することにより、時計の組立工程の減
少、コストダウンをはかつたものである。[Detailed Description of the Invention] The present invention reduces the number of assembly steps and costs of a timepiece by using the stator of the timepiece motor as a circuit board.
近年、時計の低コスト化に対する要求は苛烈で

である。 In recent years, there has been a strong demand for lower costs for watches, and conventional measures have been taken to reduce assembly processes by reducing parts. This includes, for example, integrating the dust cover and the upper plate, and integrating the lower plate and the mechanism receiving plate.
しかしながら、近年のコストダウンに対する要

新たなコストダウンの対策が要望されてきた。 However, the demand for cost reduction in recent years has become extremely strict, and it has become impossible to meet these demands using only conventional methods of reducing assembly man-hours.

題点がある。 If we look at the conventional method of assembling a watch movement, we will see that watch circuit elements such as a crystal oscillator and IC are inserted and soldered onto a circuit board, and then the stator is assembled with a watch motor coil. is placed near the circuit board, and the coil terminals are soldered to the circuit board. Two steps are required just to attach the circuit board and the stator of the watch motor, and additionally, soldering must be performed after the circuit board and stator have been assembled, so the soldering step is also a laborious process. In addition, even in watches where the circuit board is fixed to the stator, a snap fit structure is used to fix the circuit board to the stator coil bobbin in order to eliminate the need for screws to reduce the number of man-hours.
There are still various problems that need to be improved, such as the need for a step of bonding the substrate and the time-consuming process of assembly.
本考案は上記従来の課題に鑑み為されたもので
あり、その目的は、より組立工数が少なく低コス

とを特徴とする。 In order to achieve the above object, the present invention forms an insulating layer surface on the stator of a watch motor, forms a conductive pattern on this insulating layer surface, and electrically connects the timepiece circuit element to the connection terminal position of the conductive pattern. By doing so, the stator is also used as a circuit board.
以下図面に基づいて本考案の実施例を説明す

り形成される。 The stator 2 is formed in a U-shape, and is made of a ferromagnetic material, such as permalloy (trademark).
It is made of soft iron, Ni-Fe42 alloy, silicon steel, etc. Further, a coil 4 of a watch motor is inserted into one stator piece 2a. An insulating layer surface 6 is formed on the surface of the connecting portion between both stator pieces 2a and 2b. This insulating layer surface 6 is formed by coating the surface of the stator 2 with enamel or resin (eg, polyimide, epoxy, etc.).

ングする際にも、非常に信頼性が向上する。 If a circuit board is formed on the stator 2 of a watch motor as shown in this embodiment, the process of assembling an independent circuit board as required in the past can be omitted, and
Since there are fewer parts to assemble, the assembly process can be reduced, and it is also possible to make the device smaller and thinner. Also,
Since the ferromagnetic stator 2 has a much smaller coefficient of expansion than epoxy resins used in conventional circuit boards, reliability is greatly improved even when circuit elements are directly bonded.
さらに、従来のエポキシ樹脂を用いた回路基板

チの信頼性も向上する。 Furthermore, circuit boards using conventional epoxy resin become soft when exposed to moisture, so if a switch contact is placed on the board, even if you press the switch, the board absorbs the pressure and makes contact. However, in the present invention, since the stator 2 made of ferromagnetic material is used as the substrate, the substrate does not become soft or weak due to moisture, and the reliability of the switch is improved.

い。 In this example, in order to configure the substrate,
Although the insulating layer surface 6 is formed at the connecting portion of the stator 2, the insulating layer surface 6 may be formed at any portion of the stator 2, or may be formed over the entire stator 2. Further, in this embodiment, the IC 16 is connected to the conductive pattern 8 on the insulating layer surface 6 by wire bonding, but the IC 16 and the conductive pattern 8 may be connected by a flip-chip method.

る。 As described above, according to the present invention, an insulating layer surface is formed on the stator of a watch motor, a conductive pattern is formed on the insulating layer surface, and the timepiece circuit element is electrically connected to the connection terminal position of the conductive pattern. By making the stator double as a circuit board, the number of assembly steps and assembly parts of the watch can be reduced, thereby reducing costs, size, and thickness. Furthermore, since the circuit board itself is composed of a stator, the coefficient of expansion is smaller than that of paper epoxy resin, etc., so reliability is greatly improved when directly bonding circuit elements. Furthermore, it is extremely resistant to moisture, and unlike conventional paper epoxy resin circuit boards, it does not become soft due to moisture. There are various advantages, such as eliminating the possibility of sagging.
