Description

Description: TECHNICAL FIELD The present invention relates to a belt-type power supply device used for portable small electronic devices and the like.

(Prior Art) A conventional power supply device of this type will be described with reference to FIG. FIG. 1 is an exploded perspective view of a power supply device for a conventional electronic device and a belt hooking device attached to the power supply device. Electronic device 1
Is fixed to a clip pedestal 2 having a knob having pin holes on the left and right and a spring seat provided at the center. The torsion coil spring 3 is a double torsion type. Clip 4
Is intended to be worn on a waist belt or a chest pocket, and knobs provided with pin holes for attaching to the clip pedestal 2 are formed on the left and right of the upper back surface. The spring pin 5 is inserted through the pin hole, and is formed by winding a plate material.

The power supply unit 6 is an external power supply when the electronic device 1 is used for a long time, and is connected to the electronic device 1 as shown in the drawing when necessary.

To assemble such components, clip base 2
The torsion coil spring 3 is placed on the spring seat, and the clip 4 is covered with the arms on both sides bent, and the spring pin 5 is inserted into the pin holes of the clip base 2 and the clip 4 and fixed.

(Problems to be Solved by the Invention) However, in the above configuration, the electronic device 1 to which the power supply unit 6 is connected has a problem that the volume is large and the portability is poor. Further, when used for a short period of time, even if the power supply unit 6 is removed, the clip 4 projects from the back surface, which is a hindrance when it is put in an inner pocket or accessory case of clothes, and there is a problem that the storability is poor.

The present invention solves the above problems and provides a belt-type power supply device that is excellent in portability and storability.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a mount that is detachably attached to the back surface of an electronic device and is electrically connected to the electronic device, and the mount. A power supply unit that is rotatably connected to form a clip and has an external power supply mounted thereon, and a power supply unit that is disposed at a connection portion between the mount and the power supply unit and electrically connects to an electronic device through the mount. And a connection terminal for urging the power source in the holding direction.

(Operation) With the above configuration, when used for a short time, the electronic device is detached from the clip and the power source, and thus becomes a single unit, so that the electronic device can be stored easily. Further, when used for a long period of time, the power source unit, which also serves as a clip and which is equipped with an external power source such as a battery, is attached along the back surface of the electronic device, so that portability is not impaired.

(Embodiment) An embodiment of the present invention will be described with reference to FIG. FIG. 1 is an exploded perspective view showing components of a belt-type power supply device of a butterfly clip type according to the present invention and electronic equipment to which the components are mounted.

The electronic device 1 has terminals 1a and 1b on both sides and a bottom surface.
(Not drawn for perspective view) embedded trapezoidal cross-section engagement grooves 1c and 1d (not drawn for perspective view) and bottom surface thereof with rectangular cross-section engagement groove 1e A T-shaped groove is formed by combining a trapezoidal removal groove 1f having the same trapezoidal cross section as the engagement grooves 1c and 1d.

The mount 7 is a substantially T-shaped plastic molded product, and an engaging projection in which terminals 7a (not drawn for a perspective view) and 7b are embedded in the tip surface inside both wings and the tail portion bent to the back surface. Two terminals 7f and 7g, which are electrically connected to the above terminals 7a and 7b by a conductive wire embedded when the mount 7 is molded, are embedded in the center of the surfaces of 7c and 7d and an engaging projection 7e. A clip pedestal 7h with a pin hole is formed on the tab.

The connection terminal 8 has terminals 8a and 8b formed by forming leaf springs into a U shape and fixed to a base provided with a pillow portion having pin holes.

The power supply unit 6 which houses a battery as an external power supply has knobs 6a and 6b each having a pin hole for engaging the above-mentioned clip pedestal 7h formed on the upper surface of the back surface.
Terminals 6c and 6d connected to the connection terminal 8 are buried.

The spring pin 5 is formed by winding a plate material.

In order to assemble a butterfly clip type power supply device composed of such components, a clip pedestal 7h formed on the surface of the mount 7 is connected to a connecting terminal 8 so that the corresponding pins are aligned.
Then, the spring pin 5 is inserted into the pin hole while pushing the power source unit 6 so that the pin holes of the knobs 6a and 6b of the power source unit 6 are in line with the pin hole. When the assembly is completed, the terminals 6c and 6d of the power supply unit 6 are connected to the terminals 8a and 8b of the connection terminal 8, the terminals 7f and 7g of the mount, the lead wires (not shown), and the terminals 7a and 7a of both wings of the mount 7, respectively. Electrically connected to 7b.

The operation of the belt-clip type power supply device of the butterfly clip type configured as described above will be described.

To attach the butterfly clip type power supply device to the electronic device 1, first, the engaging protrusion 7e on the tail portion of the mount 7 is fitted into the engaging groove 1e on the bottom surface of the electronic device 1. Next, the mount 7 is attached to the electronic device 1
When lightly pressed against, both wings of the mount 7 are opened, and the engaging protrusions 7c and 7d ride over both side surfaces of the electronic device 1 and fit into the engaging grooves 1c and 1d, and at the same time, they are securely mounted mechanically. , The terminals 7a and 7b and the terminals 1a and 1b are in contact with each other, and are electrically connected to the power supply unit 6.

In this state, if the power supply unit 6 is inserted into the belt, the terminals 8a and 8b of the connection terminal 8 elastically bend and the electronic device 1 is easily
Can be attached to the belt.

To remove the butterfly clip type power supply device, lift the tail of the mount 7 away from the electronic device and pry it to the left or right, the engaging protrusion 7e easily moves in the removal groove 1f of the electronic device 1, and Since the fitting protrusions 7c and 7d climb the inclined surfaces of the engagement grooves 1c and 1d having a trapezoidal cross section, the mount 7 can be easily removed.

(Effects of the Invention) As described above, according to the present invention, a belt-type power supply device can be easily attached to and detached from an electronic device, can be securely attached, has a small volume, and is excellent in portability. If the electronic device is removed, an electronic device with good storability that does not have a protruding accessory can be obtained, and assuming that the electronic device is used with the power supply unit installed, work to replace the internal power supply of the electronic device Compared with the above, since the power supply device can be easily replaced with respect to the electronic device, the replacement work of the consumable power supply becomes easy.

Further, since it has a function as a clip, it can be commonly used for a plurality of types of electronic devices.

Further, the belt-hung type electronic device with a power supply device, which is excellent in portability and storability, is not only small in size and helps to improve the product image, but also the cost can be reduced by making the power supply device common.
