なるため、組立性が良くなる。 Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention contributes to the improvement of a battery connection structure for an electronic timepiece . An example of a battery connection structure of a conventional electronic timepiece is shown in FIGS. 1 and 2. In FIG. 1, 1 is a battery lead terminal, 1a is the battery lead terminal battery spring portion, and 1b is the battery lead terminal fixing portion. Reference numeral 2 is a battery, 3 is a metal base plate, 4 is a screw pin, 5 is a battery lead insulating frame, 6 is a circuit board, 7 is a circuit receiver, 8 is a fixing screw, and 11 is an insulating tape. Further, in the figure, A indicates the bending position of the battery lead terminal battery spring portion 1a, and φ11 indicates the hole diameter in the battery lead terminal fixing portion 1b. In this structure, since the battery lead terminal 1 is an insulating structure formed by the collar of the battery lead insulating frame 5, it is necessary to make the hole diameter φ11 of the battery lead terminal large, and at the same time, the battery lead terminal battery spring portion 1a. Since it is necessary to set the bending position A in a position apart from the screw fixing portion to some extent, there is a drawback that a planar and sectional space is required. In FIG. 2, 1c is a battery lead terminal lead portion, 9 is a plastic base plate, 10 is a base plate reinforcing plate, and 9 is a base plate reinforcing plate.
Reference numeral a is a guide dowel for the circuit board 6 and the circuit receiver 7. Reference numerals 1c 'and 6'represent the states of the battery lead terminal lead portion 1c and the circuit board 6 before being assembled, respectively. Reference numeral 8 in the figure shows the amount of deflection of the battery lead terminal lead portion 1c when the circuit board 6 and the circuit receiver 7 are assembled. In this structure, the battery lead terminal 1c acts as a spring portion fixing the battery lead terminal fixing portion 1b, and in order to obtain a constant contact pressure, only the flexure 8 is lifted when the circuit board 6 and the circuit receiver 7 are assembled. Causes
It has a drawback that the assembling property is poor and the guide dowel 9a must be set well. In addition, since the fixing portion has a screw fixing structure made of a plastic material, creep is likely to occur. Further, there is a drawback that a planar and cross-sectional space is required in order to adopt the screw fixing structure similar to that shown in FIG. SUMMARY OF THE INVENTION In order to eliminate these drawbacks, the present invention eliminates a complicated screw fixing structure to suppress creep in a plastic material and, at the same time, to provide a simple dowel structure. By utilizing it, it is possible to effectively utilize the space. In addition, it is possible to improve the embedded name of a circuit board or the like. A battery connection structure for an electronic timepiece according to the present invention is a battery, a base plate having a storage portion for the battery, a circuit board mounted on the base plate, and a base plate mounted on the base plate. In the battery connection structure of an electronic timepiece having a battery lead terminal that is electrically connected to the battery, the main plate is
A dowel is formed near the portion, and the battery is inserted into the dowel.
The battery lead terminal and the circuit board in the state before
Between the battery lead ends
The child is a battery at one end and a circuit board at the other end with the dowel as a fulcrum.
And is swingably engaged with the dowel,
When the battery is stored in the storage portion, the battery lead end
The child flexes around the shoulder of the dowel as a fulcrum,
The lead terminal is generated by the moment when the contact pressure is obtained on the pole.
Is characterized in that the other end of the is brought into pressure contact with the circuit board.
You. Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 3 is a sectional view of an embodiment of the present invention. 1
Reference character a'denotes the shape of the battery lead terminal battery spring portion 1a before the battery 2 is inserted. 9a and 9b are plastic base plates 9
9a is a guide dowel and 9b is a stepped dowel. Here, the plastic base plate 9 may be a metal base plate in consideration of insulation. 12 is a train wheel bridge, 13
Is a gear. Here, in a plan view, the train wheel bridge 12 and the gear 13 may overlap the stepped dowels 9b and 9a. Further, B in the figure is a shoulder of the stepped dowel 9b of the plastic base plate, which is a fulcrum of the swinging movement of the battery lead terminal 1. φ12 is the dowel diameter of the stepped dowel 9b, φ13
Indicates the dowel diameter of the guide dowel 9a. h indicates a swingable distance when the battery lead terminal is incorporated. In FIG. 3, in a state before the battery 2 is inserted, the battery lead terminal 1 uses the step B of the stepped dowel 9b of the plastic base plate 9 as a fulcrum, and the battery lead terminal lead portion 1c serves as the circuit board 6. The circuit board 6 can be swung for a distance h between them, and the circuit board 6 is not lifted when the circuit board 6 is assembled. Battery lead terminal Battery spring 1a 'is the battery 2
In the state after the insertion, the battery lead terminal is bent to the battery spring portion 1a with the shoulder B of the stepped dowel 9b of the plastic base plate 9 as a fulcrum to obtain the contact pressure with the cathode of the battery, and at the same time, due to the moment. For the first time, the circuit board 6 and the battery lead terminal lead portion 1c come into contact with each other with a constant contact pressure. In this structure, the battery lead terminal lead portion 1c does not bend before the battery 2 is inserted, and the circuit board 6 and the circuit receiver 7 are not lifted when assembled. Also, the hole diameter φ11 of the battery lead terminal shown in FIG. 1 is less than half the hole diameter φ12 of the stepped dowel 9b and the guide dowel diameter φ3 in FIG. Becomes Further, the shape of the present invention can be implemented not only in a linear swingable shape, but also in a curved swingable shape depending on the relation of the assembling space. As described above , according to the present invention, the battery

The battery lead terminal has the dowel as a fulcrum.
Connect one end to the battery and the other end to the circuit board
And is swingably engaged with the dowel so that the battery is
When stored in the storage section, the battery lead terminals are
It bends around the shoulder of the step as a fulcrum and contacts the cathode of the battery with contact pressure.
At the same time as
Is pressed into contact with the circuit board to insert the battery.
