Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a battery storage structure.

[Prior Art] Conventionally, as a battery storage structure, for example, in a timepiece device, a frame is provided with a hole for storing the battery in parallel, and both positive and negative battery contacts are attached at right angles to the opening surface of the hole. There is known a battery housing structure in which one piece contacts each of both electrodes of the battery.

[Problems to be Solved] However, in the conventional battery storage structure, in order to remove the battery, a method of pressing the corner of the positive electrode side of the battery to the negative electrode side with a finger and pulling it toward you at the same time is taken. However, the urging force of both battery contact pieces in the axial direction of the battery was strong, and a strong force was applied to the fingertips for taking out the battery, making it difficult to take out the battery.

Therefore, an object of the present invention is to provide a battery storage structure that allows easy insertion and removal of batteries.

[Means for Solving the Problems] In order to achieve the above object, the battery storage structure of the present invention is characterized by a frame having holes for vertically storing the battery,
It is swingably attached to the frame in the vicinity of the hole parallel to the opening surface of the hole, and consists of a battery contact piece that contacts the electrode of the battery.The battery contact piece engages with the inner peripheral edge of the hole and swings. It is in the place where the vertical bending part that regulates the moving angle is formed. More preferably,
Two holes are provided, at least one battery is housed in the opposite direction, and two battery contact pieces are coaxially swingable and electrically connected. One of the battery contact pieces contacts the positive electrode of the battery and the other contacts the negative electrode of the battery.

Therefore, the battery contact pieces 14 and 15 are swingable about the support column 13 in parallel with the opening surface of the hole 1d, and the two are provided in an electrically conductive state. A stopper seat 16 is attached to the tip portion 13a of the support column 13 so that both battery contact pieces 14 and 15 do not fall out. Vertically bent portions 14a and 15a are formed on both battery contact pieces 14 and 15 to engage with the inner peripheral edge portions of the holes 1d and 1d to regulate the swing angle.

In FIG. 7, the positive electrode 12a of one battery 12 housed in the battery housing chambers 1e, 1e formed integrally with the mounting plate 1 is
The positive electrode 12b of the other battery 12 is in contact with the positive battery contact piece 14, and the negative electrode 12b of the other battery 12 is in contact with the negative battery contact piece 15. On the opposite side of the hole 1d of the battery storage chamber 1e, both battery contact pieces 14 and 15 located on the hole 1d side, a negative battery contact piece (not shown) and a positive battery contact piece 17 (first 1) is attached to a rib 1f (first shown) extending from the mounting plate 1.

In FIG. 1, below the front frame 6, a pair of tongues 6b, 6b extending to the back surface of the battery cover 18 are formed.
The b is fixed to the support plate 1c of the mounting plate 1 with screws 19.
The screw 19 is hidden from the outside by attaching the battery cover 18 to the hole 5b formed in the rear frame 5. In addition to the timepiece machine body 3, the mounting plate 1 has other components such as a snooze switch 20, a digital display block 21, and a set switch 2
2, a sounding body 23, and a sound stop switch 24 (shown in FIG. 8) are connected to the circuit board 11 by lead wires (not shown). A pointer 25 is located between the dial 2 and the front cover 7, and this pointer is attached to a pointer shaft 26 protruding from the timepiece mechanical body 3 and penetrating the dial 2. The snooze button 27 is engaged with the upper part of the snooze switch 20, and the set switch 22
The set button 28 is engaged with the
A stop button 29 (shown in FIG. 8) is engaged with this.

Next, storage and removal of the battery will be described. The watch is held upside down, that is, the battery cover 18 is held up, and the battery cover 18 attached to the hole 5b of the rear frame 5 is pulled toward the rear of the rear frame 5 to remove it from the rear frame 5. . Next, make sure that the positive battery contact piece 14 and the negative battery contact piece 15 do not cover the holes 1d, 1d of the support plate 1c.
4, Hold each of the vertical bending portions 14a, 15a of the minus battery contact piece 15 and rotate them around the support column 13 as the center of rotation to form the holes 1d, 1
Evacuate from d.

Next, the negative battery contact piece attached to the rib 1f is a battery
The negative electrode of 12 and the positive electrode of the battery 12 contact the positive electrode of the battery 12 so that the positive electrode of the battery 12 contacts the battery 1
Insert 2, 12 into the battery compartment 1e, 1e. Next, while pressing one side of the battery 12 with a finger, a battery contact piece that elastically contacts this battery, for example, a positive battery contact piece 14, grasps the upright bent portion 14a, and the support pillar 13 is the center of rotation of the battery 12 The battery 12 is fixed by swinging and rotating to the center of the pole 12a and releasing the finger. In this state, the minus battery contact piece attached to the rib 1f exerts an urging force on the plus electrode 12a of the battery 12 and the plus battery contact piece 14.

Similarly, while pressing the other side of the battery 12, the minus battery contact piece 15 is grasped at its upright bent portion 15a and rocked and rotated to the center of the minus pole 12b of the battery 12 with the supporting column 13 as the center of rotation. Fix the battery 12. In this state, the positive battery contact piece 17 attached to the rib 1f exerts an urging force on the negative electrode 12b of the battery 12 and the negative battery contact piece 15. Next, the battery cover 18 is pushed in from the rear side of the rear frame 5 toward the front side and attached.

Next, when the time to replace the battery comes
When removing from 1e, 1e, first, the timepiece is held with the battery cover 18 facing upward, and the battery cover 18 attached to the hole 5b is pulled in the rear direction of the rear frame 5 and removed from the rear frame 5. Next, the positive battery contact piece 14 and the negative battery contact piece 15 are gripped by the vertical bending portions 14a and 15a, respectively, and the support column 13 is used as the center of rotation for the position shown by the imaginary line in FIG. The positive battery contact piece 17 or the negative battery contact piece attached to the rib 1f up to the upper side of FIG. 7 is oscillated and rotated in a direction perpendicular to the direction in which the batteries 12, 12 are biased. If the snooze button 27 is turned upside down from this state, the batteries 12 and 12 are naturally dropped from the battery storage units 1e and 1e by their own weight and taken out.

[Effect] As described above, according to the present invention, a hole for vertically accommodating a battery is formed in the frame (mounting plate), and the hole is attached to the frame in the vicinity of the hole so as to be swingable in parallel with the opening surface of the hole. Since the vertical bending part that engages with the inner peripheral edge part and regulates the swing angle is formed, the urging force that the battery contact piece applies in the axial direction of the battery when removing the battery and the force that swings the vertical bending part. Since the direction is at a right angle, a weak force is required to swing the vertical bending portion with a fingertip to take out the battery, and the battery can be easily inserted and removed.
