Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging device for a rechargeable vacuum cleaner mainly used for cleaning general households.

2. Description of the Related Art Conventionally, a charging device for a rechargeable vacuum cleaner of this type has a structure shown in FIG. In FIG. 5, reference numeral 1 denotes a charger, which has a transformer and a rectifier built therein, and an external recess provided with charging terminals 2 and insulating ribs 3 standing upright.
The inside of the rib 4 that fits the protrusion of the cleaner body was configured. Reference numeral 5 denotes a cord drawing portion, which has a plug (not shown) at the other end thereof, and when the plug is inserted into an outlet (not shown), charging of 2 is performed through a transformer and a rectifier built in one charger. It was to energize the terminals.

Problems to be Solved by the Invention In such a conventional configuration, when a conductive object such as a coin is dropped inside the rib of 4, there is a problem that the pair of charging terminals 2 are electrically connected and short-circuited by the coin. . The present invention solves such a problem, and an object thereof is to prevent a pair of charging terminals from conducting or shorting even if a conductive object such as a coin is dropped.

Means for Solving the Problems In order to solve this problem, the present invention provides a pair of charging terminals and a pair of insulating ribs that are substantially orthogonal to the charging terminals, respectively. When the space distance between a pair of insulating ribs is made smaller than the space distance between terminals, and the charging terminal and its surroundings are tilted toward you, dropping coins etc. It is configured so that it will not slip off and the charging terminal will not conduct or short-circuit with a coin.

Therefore, with this configuration, even if a conductive object such as a coin is dropped, the pair of charging terminals are not electrically connected or short-circuited.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the figure, 11 is a charger, which has a built-in transformer and a rectifier, and a pair of charging terminals 12 and a pair of insulating ribs 13 are erected in the external recesses,
It constitutes the inside of 14 ribs. Reference numeral 15 is a cleaner body, which houses a storage battery, a motor, a fan, leads, etc., and has a protrusion 16 at the bottom thereof, and a pair of grooves 17 are provided on both side surfaces thereof. Has a pair of charging terminal fitting portions 18. Now, in order to insert the cleaner body of 15 into the charger of 11, by fitting the groove 17 in the lower part of the cleaner body of 15 to the pair of ribs 13 standing on the charger of 11, The lead in the charging terminal fitting portion 18 at the bottom of the cleaner body of 15 is connected to the 12 charging terminals standing on the charger. In this state, plug 19 plug into an outlet (not shown)
15 The internal storage battery is charged. Note that the 12 charging terminals and their surroundings are inclined so that the front side will be lower, and if a coin or the like is dropped on this, it will slide down and the 12 charging terminals will not conduct or short-circuit. Absent.

EFFECTS OF THE INVENTION As described above, according to the present invention, a pair of charging terminals and a pair of insulating ribs substantially orthogonal to the charging terminals are provided upright,
Since the space distance between the pair of insulating ribs is smaller than the space distance between the pair of charging terminals, and the charging terminal and the periphery of the charging terminal are inclined toward the front, the coin Even if a short-circuited object such as spills, the charging terminals will not conduct and short-circuit.
