Abstract

A power supplying device for flashes includes a base having a bottom formed with two opposite grooves, a threaded hole vertically extending therethrough, and two threaded holes, at least a rechargeable battery having a top provided with two conducting terminals and a protuberance, an extension cord provided at one end with a plug engageable with a power socket of the battery and at another end with a socket, and a power cord having an end provided with a plug engageable with the socket of the extension cord and another end provided with a positive and negative wires each provided with a metal conductor. One of the wires has a buzzer. A circuit protecting switch and a metal conductor are fitted within a cylinder with the metal conductor partially projected out of an end of the cylinder. Another one of the wires is provided at an end with a metal conductor which is fitted within another cylinder and partially extends out of the cylinder. Hence, the power supplying device can be easily mounted on the camera platform of a camera for supplying power to the flash of the camera.

Claims

1. A power supplying device for flashes comprising:

a base having a bottom formed with two opposite grooves, a threaded hole vertically extending therethrough, and two threaded holes;

at least a rechargeable battery having a top provided with two conducting terminals and a protuberance, said protuberance being connected to a button slidably fitted in one end of said battery, two opposite sides of said battery being formed with two longitudinal flanges configured to engage with said grooves of said base, a bottom of said battery being provided with two grooves configured to engage with two flanges of a similar battery, a conducting member and a recess respectively engageable with a conducting terminal and protuberance of a similar battery, a central portion of said battery having a vertical threaded hole adapted to engage with a camera platform of a tripod, and a power socket provided close to said button for supplying power;

an extension cord provided at one end with a plug engageable with said power socket of said battery and at another end with a socket; and

a power cord having an end provided with a plug engageable with said socket of said extension cord and another end provided with a positive and negative wires each provided with a metal conductor, one of said wires having a buzzer, a circuit protecting switch and a metal conductor which are fitted within a cylinder with said metal conductor partially projected out of an end of said cylinder, another one of said wires being provided at an end with a metal conductor which is fitted within another cylinder and partially extends out of the another cylinder, said circuit protecting switch being used for cutting off power supply in case of short circuit and turning on said buzzer to arouse a user to check polarity.
