Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage battery with a charger which can be charged as it is even when connected to an external device.

[0002]

2. Description of the Related Art As shown in FIG. 10, conventionally, a storage battery 9 used as a power source for a VTR integrated video camera has only a storage battery portion 3 inside a case 2. Therefore, the storage battery 9 and the charger 8 are separate bodies, and the storage battery 9 is attached to the charger 8 for charging. The storage battery 9 has engaging portions 6a and 6b and terminals 7a and 7b at the upper and lower ends thereof. Meanwhile, the charger 8
Has a storage battery insertion portion 11. At the upper and lower ends of the storage battery insertion portion 11, there are charger side engaging portions 12a and 12b, and the storage battery 9
By inserting in the direction of arrow C, engaging portions 6a, 6b
Is engaged with the charger side engaging portions 12a and 12b, and the storage battery 9
Is fixed to the charger 8. The storage battery 9 is prevented from coming off the charger 8 by the lock claw 13. The terminals 7a and 7b of the storage battery 9 are in sliding contact with the output terminals 17a and 17b of the charger 8, and the current from the charger 8 flows into the storage battery 9. When the power cord 10 is connected to the outlet, the power lamp 14 is turned on, and when the storage battery 9 is attached to the storage battery insertion portion 11, the storage battery detection switch 25 is activated and the charging lamp 15 is turned on to start charging.

Further, Japanese Patent Application Laid-Open Publication No. 3-23668.
No. 8 describes a technique in which a storage battery and a charger are integrated.

[0004]

The above-mentioned conventional technique has a problem that the storage battery 9 cannot be charged without the charger 8 because the storage battery 9 and the charger 8 are separate bodies. That is, the opportunity was lost when the storage battery 9 was charged.

Further, Japanese Patent Application Laid-Open Publication No. 3-23668.
The technology of integrating the storage battery and the charger described in No. 8 is
Although it solved the problem of the loss of this opportunity,
Since the charger is arranged between the VTR-integrated camera and the storage battery and the power plug is provided on the engagement surface with the VTR-integrated camera, the storage battery with the charger is always connected to the VTR when charging the storage battery. It has to be removed from the integrated camera, and there is a problem that charging cannot be performed with the storage battery with a charger attached to the VTR integrated camera.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a storage battery with a charger which can be charged while mounted in a VTR integrated camera.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and in a storage battery with a charger used by engaging with an external device, the storage battery and a charger for charging the storage battery. And a charger which is disposed on a portion other than the engagement surface with the external device and is connected to the charger, and a terminal for energizing the external device from the storage battery. A storage battery is provided.

As another aspect, in a storage battery with a charger that is used by being attached to an external device,
A charger for charging the storage battery, a case containing the storage battery and the charger, a power plug for energizing the charger, and a terminal for energizing the external device with the power stored in the storage battery. The case has an engaging portion that engages with the external device, and a storage portion that stores the power plug inside and / or outside the case, and the power plug has the storage portion. When it is not housed, it protrudes from the surface of the case other than the engaging surface with the external device, and when housed, it can be housed without protruding from the surface of the case. A storage battery with a charger is provided.

[0009]

Since the storage battery is integrated with the charger, the storage battery can be charged reliably without being attached to the charger.
Further, since the power plug is provided at a place other than the engaging surface with the external device, for example, the VTR integrated camera, the battery can be charged even with the storage battery attached to the external device. Moreover, since the power plug can be stored in the storage portion, it does not interfere with the operation.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a storage battery 1 with a charger showing an embodiment of the present invention. A storage battery 1 with a charger has a case 2 in which a storage battery unit 3 and a charger unit 4 are integrally configured and housed. Power plugs 5a and 5b are protruded in the lower part of the case 2 in the arrow A direction from windows 23a and 23b provided on the side surface 6d of the case 2. Power plugs 5a and 5b are indicated by arrow B
It can be moved in any direction and can be stored inside the case 2. Further, by pulling out in the direction A, the configuration shown in FIG. VTR on the top and bottom of case 2
Engagement portions 6a, 6b for attaching to the integrated video camera
Is formed and terminals 7a and 7b for supplying electric power are installed.

The structure of the power plugs 5, 5a, 5b will be described with reference to FIGS. 2 shows a storage battery 1 with a charger.
The cross section of the charger part 4 of FIG.
It is the figure which looked at from the bottom.

Inside the case 2, a storage battery section 3 is provided on the upper side, a charger section 4 is provided on the lower side, and power source plugs 5, 5a, 5b are provided further below the charger section 4. The power plugs 5, 5a, 5b have their rear ends fixed to the slider 20, and a part of the power plug 5, 5a, 5b projects above the slider 20 as a contact portion 26. The power plugs 5, 5a, 5b project outside from a window 23 formed in the case 2.

The inner bottom surface of the case 2 has a front recess 22a.
And a rear recess 22b and a step portion 24 are formed.
When the power plugs 5, 5a, 5b are completely pulled out to the outside, the slider 20 is in the state of being fitted in the front recess 22a. In this state, since the lower portion of the slider 20 is in contact with the step portion 24, the power plugs 5, 5a, 5b are not pushed into the case 2 by the force received from the outside.

Above the slider 20, the contact piece 18,
21 is attached downwards by rivets 19. A tab 17 is fixed to the rivet 19 on the opposite side of the surface on which the contact pieces 18, 21 are attached. The contact pieces 18, 21 are made of a spring material and the ends 18a, 18b, 21a, 21b of the contact pieces 18, 21 are made.
Always presses the contact portions 26 of the power plugs 5, 5a, 5b. As a result, the contact pieces 18, 21 and the power plug 5,
The contact portions 26 of 5a and 5b can be reliably contacted with each other, and the slider 20 can be stably inserted into the depressions 22a and 22b. The tab 17 contacts the contact piece 1 via the rivet 19.
8 is electrically connected to the power plug 5, 5a, 5a
The electric power input from b is transmitted to the charger unit 4.

The engaging portion 6b has a terminal 7b and supplies the electric power of the storage battery 1 with a charger when the storage battery 1 with a charger is attached to a VTR integrated video camera.

The operation of the power plugs 5, 5a, 5b will be described with reference to FIGS.

In order to store the power plugs 5, 5a, 5b inside the case 2, the slider 20 is brought into contact with the contact pieces 18, 21 through the opening 27 formed in the lower surface of the storage battery 1 with a charger.
Push the spring pressure up. And as it is,
Push the slider 20 to the left in the figure. As a result, the slider 20 moves to the left beyond the step portion 24 and stops when it hits the wall 28.

When the force pushing the slider 20 upward is loosened, the contact pieces 18b and 21b again push the contact portion 26 downward, so that the slider 20 fits into the recess 22b. In this state, since the step portion 24 blocks the movement of the slider 20, the power plugs 5, 5a, 5b do not protrude from the inside of the case 2 even if the storage battery 1 with a charger receives vibration from the outside.

Another embodiment will be described.
