Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device such as a portable telephone terminal or a portable electronic notebook in which a general dry battery and a rechargeable battery can be used in addition to a battery for power supply.

[0002]

2. Description of the Related Art Conventionally, portable electronic devices such as portable telephone devices and portable electronic organizers have been powered by a dedicated battery.

However, the dedicated battery had to be charged in advance for a time determined according to the battery capacity. Therefore, I forgot to charge it,
Since the charging time cannot be taken, the battery voltage becomes insufficient, and the battery may not operate normally or may not operate normally.

Therefore, recently, instead of a dedicated battery,
Commercially available, inexpensive dry batteries and those that use rechargeable batteries of the same shape as these dry batteries have come out.
As a result, no inconvenience such as insufficient battery voltage will occur anywhere. However, since a dry battery or a rechargeable battery cannot be mounted as it is, a battery case having the same shape as a dedicated battery, which is separately provided, is housed as a power supply unit.

With reference to FIG. 5, a portable electronic device containing a power source unit including a dedicated battery and a battery case will be described.
Here, the electronic device is a mobile phone, but other devices can be similarly configured.

The front portion 1 and the rear portion 2 are combined together, and the power source 3 is engaged with the storage portion 21 of the rear portion 2 to supply power. The front part 1 includes a speaker part 11 for outputting a received sound, a display part 12 for performing various kinds of display, a key input part 13 in which numeric keys and telephone-related keys are arranged,
It has a concave portion 14 for fitting. Also,
The rear surface portion 2 accommodates an antenna and protects the antenna accommodating portion 22, and an elastic recess 23 used for fitting with the power supply portion 3.
And a recessed accommodating portion 21 for accommodating the power supply portion 3.

The power supply section 3 is elastically deformed and fitted with a convex section 31 provided at a position opposed to the concave section 14 for fitting with the rear surface section 2 so that the power supply section 3 does not easily come off. The elastic portion 32 and the elastic convex portion 33 provided on the elastic portion 32 and fitted with the elastic concave portion 23 are provided.

Next, details of the power supply unit 3 will be described. Originally,
The power supply unit 3 is composed of only a dedicated battery. Therefore, when the dedicated battery is incorporated, it becomes as shown in FIG. On the other hand, when various batteries are assembled using the battery case, the external appearance is similar to that shown in FIG. However, since the shape of the battery itself is different, the battery will be mounted in the battery case.

FIG. 6 illustrates the structure of the portion in which the battery is fitted. This figure is a view of the power supply section 3 as seen from the storage side of the rear surface section 2. The power supply section 3 is divided into a battery storage section and a battery storage lid section (shown in FIG. 7) that covers the battery storage section. The battery accommodating portion includes the convex portion 31, the elastic portion 32, and the elastic convex portion 3 described above.
In addition to 3, L for positioning and fixing the outer frame 34 and the lid 4
The rib 35, the groove 36, the recess 39 for accommodating the battery 5 such as a dry battery or a rechargeable battery, the spring-shaped first terminal 37a in contact with the voltage terminal at one end of these batteries, and the voltage terminal in the other end It is provided with a second terminal 37b, a third terminal 38a and a fourth terminal 38b that internally connect the first terminal 37a and the second terminal 37b in series and output a predetermined voltage.

FIG. 7 is a view showing a battery storage lid portion which covers the battery storage portion. FIG. 6A is a view as seen from the storage side of the rear surface portion 2, and FIG. 6B is a view as seen from the battery storage unit side. The lid portion 4 constituting the battery housing lid portion engages with the L-shaped rib 35 and has a notch portion 41 provided with a notch for fixing, and charges the voltage from the charger or supplies power to the main body. In order to supply the power supply terminals 42a, 42b to the power supply terminals 42a, 42b and the voltage supplied from the third terminal 38a, the fourth terminal 38b, to the back surface of which the battery voltage is supplied, to the power supply terminals 42a, 42b via the wiring inside the lid. The first contact 43a, the second contact 43b, and the groove 36
It is provided with a convex portion 44 that engages with and positions and fixes.

Then, the lid portion 4 is placed in the battery housing portion so as to cover the battery (FIG. 8) and slid in the direction of arrow A, so that the L-shaped rib 35 and the claw portion 41, the groove portion 36 and the convex portion 44.
Are engaged and positioned and fixed. FIG. 8 shows a state before the lid portion 4 is slid, and thereafter, the lid portion 4 is fixed by sliding in the direction of arrow A.

By providing a stepped projection (not shown) on the claw 41, the lid 4 can be fixed more firmly.

On the other hand, when the lid 4 is disengaged, it can be easily disengaged by sliding it in the direction opposite to the arrow A direction. Also, the surface of the lid 4 should be processed so that it does not slip,
By attaching the non-slip, attaching the lid part 4,
It can be removed easily.

Next, a charger for charging will be described. FIG. 9 is a diagram showing a method of mounting the charging battery mounted on the telephone body and the charging battery for charging the charging battery alone. That is, even if the power source unit 3 is removed from the rear surface unit 2, the power source unit 3 can be mounted in a charging place dedicated to the power source unit for charging.

Charging terminals 3a, 3 provided under the power supply unit 3
When b and 3c are attached to the rear surface portion 3, charging is performed by contacting the battery charging terminals 51a, 51b and 51c of the charger 5, but when the battery is removed, the battery charging terminals 52a and 52b of the charger 5 are removed. , 53 to charge the battery (explained by the XY partial sectional view in FIG. Since the battery charging terminal 53 also serves as a discharging terminal, the battery charging terminal 53 is provided on the side surface so as to be distinguished from the charging terminal 51c provided at the lower portion, and the battery is discharged. That is, the terminal 53 is a charging / discharging terminal, and charging / discharging is performed by switching charging / discharging and controlling the voltage of the battery by a separately provided setting key. This is because when the charging terminal 51c is allowed to discharge, if the user touches this terminal for some reason, the charging voltage is discharged, which is inconvenient for the terminal. Therefore, since the power source terminal 42a, which can be contacted when the power source section 3 is detached from the rear surface section 2, is used to perform the discharge, this is achieved by connecting the power source terminal 42a and the charging / discharging terminal 53. You can

[0017]

However, in this conventional example, the power source unit 3 having a built-in battery is mistakenly turned upside down and mounted on the charger 5 with the power source unit 3 facing downward, and then removed. When attempting to remove the charging / discharging terminal 53, the charging / discharging terminal 53 may be caught in the gap between the outer frame 34 and the lid portion 4 that is generated when the lid portion 4 and the power source portion 3 are slid to fix each other. As a result, a strong load is applied to the terminal 53, and the terminal 53 may be deformed.

Therefore, if the corners of the outer frame 34 facing the gap are ground so as not to be caught, and the outer frame 34 is rounded, the problem can be solved. However, since a waterproof function is provided between the power supply section 3 and the rear surface section 2, close contact is considered important. Contrary to that, it is impossible to have roundness. It was

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A power supply unit according to an embodiment of the present invention is shown in FIG. The same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 is a view showing a battery accommodating portion of the power supply section shown in FIG. 6 of the conventional example. In this figure, a portion different from the conventional example is provided with a moving member 6 which is movable in a direction perpendicular to the engaging direction of the lid portion 4 in the battery housing portion. That is,
The moving member 6 can move in the direction of arrow B.
The moving range of the moving member 6 is restricted, and the moved position always overlaps the position on the extension line of the power supply terminal 42b of the lid portion 4 symmetrically arranged from the center line.

FIG. 2 is a view showing a battery storage lid portion which covers the battery storage portion shown in FIG. FIG. 6A is a view as seen from the storage side of the rear surface portion 2, and FIG. 6B is a view as seen from the battery storage unit side. The lid portion 4 forming the battery housing lid portion is cut out from the conventional example by at least the notch portion 45 having the width of the moving member 6. The notch position of the notch portion 45 coincides with the position of the moving member 6 most centered, and the moving member 6 has the notch portion 45 at this position.
It fits in and fits into.

Next, the fitting of the lid 4 will be described with reference to FIG. The lid 4 is slid in the direction of arrow A and fitted therein, as in the conventional example. However, since the moving member 6 is provided, the lid 4 cannot be fitted unless the moving member is at the desired position. That is, when the moving member is moved to the most center, it becomes possible to start the sliding for fitting the lid portion 4 (the position of the moving member in FIG. 3).

When the lid 4 is slid in the direction of arrow A and the fitting is completed, the moving member 6 can move in the direction of arrow B (left and right) due to the gap created by the sliding. By the way, during fitting, the movement of the moving member 6 is restricted by the notch portion 45 and does not move.

Thus, when the fitting is completed, the moving member 6 is moved by the user in the direction away from the center so that the fitting of the lid 4 is not released.

On the other hand, the fitting is released by the moving member 6
Can be achieved by moving the cover member 4 in the direction opposite to the direction of arrow A by moving the cover member 4 to the center and overlapping the positions of the moving member 6 and the cutout portion 45.

Next, consider the case where the power source unit 4 is inserted into the charger 5. When the power supply unit 4 is inserted as usual, the power supply terminal 42a comes into contact with the charging / discharging terminal 53, and charging or discharging is performed. However, if it is inserted by mistake in the opposite direction, the charging / discharging terminal 53 comes into contact with the outer frame, and then passes over the moving member 6 to reach the lid portion 4. After that, even if it is attempted to be removed, the charging / discharging terminal 53 is not caught unlike the conventional example.

The difference in catching between the conventional example and the present invention will be described with reference to the sectional view of FIG. The figure a is a conventional example, the figure b
Illustrates the present invention. When attempting to pull out the power supply unit 4 in the direction of the arrow C, the charging / discharging terminal 53 is caught on the corner of the outer frame 34 as described above at the location of S1. Specifically, a boundary contact between the charging / discharging terminal 53 and the contact portion 50 (specially referred to as a cover ring: for ensuring reliable contact with the power source section) provided on the charging / discharging terminal 53. This is because the corners of the outer frame 34 are caught in the.

However, the charging / discharging terminal 5 is shown in FIG.
Since the contact portion 50 of No. 3 rides on the moving member 6 that is one step lower than the outer frame 34, the boundary contact point between the charging / discharging terminal 53 and the contact portion 50 can be smoothly moved without being caught. Further, since the moving member 6 has a rounded portion in contact with the charging / discharging terminal 53, it can be moved more smoothly.

[0030]

According to the present invention, the charging / discharging terminal 5 is mounted on the charger 5 in the wrong direction by the moving member 6 and then detached.
Make sure that the power supply unit 3 is not caught by the unit 3.

Further, since the moving member 6 is lower than the outer frame in contact with the accommodating portion 21 of the power source portion 3, it can be smoothly attached to and removed from the charger 5 in the wrong direction.

Further, since the moving member 6 has a round shape, it can be removed more smoothly.
