Description
~ 60 B~ 87 This invention relates to rechargeable batteries and more particularly to a simple, inexpensive, charging system whereby a rechargeable battery of the 9 volt physical size and/or electrical characteristics is selectively and alternatively connectible to a charge current source for recharging of the type described in U. S. Patent No. 4,009,429 iss~led February 22, 1977.
There is an increasing number of consumer products being opexated by rechargeable cells sueh as nickel-cadmium cells. These products require cells with a plurality of physical sizes and electrical characteris-tics.
The variety of cell types in wide use in the consumer market has given rise to the need to provide a unitary charging deviee to accomodate the various cell types.
One such device is described in U. S. Pa-tent No. 3,579,075 issued on May 18, 1971 and assigned to the assignee of the invention herein. While this devices provides a viable approach for charging cells of the variety of types, it has failed to achieve widespread adoption in the consumer market because of its complexity and eost of eonstruction.
The system described in the above-identified U. S. Patent No. 4,009,429 is useful in charging AA, C & D size batteries, but does not aecept 9 volt si~e batteries.
Canadian applieation Serial No. ~26,565 filed April 27, 1979 discloses an improved system for 9 volt rechargeable batteries with the use of an adapter. Canadian application Serial No.f327,963 filed May 17, 1979 utilizes in eombinati~n a eharger and 9 volt size battery which are interconnected by an adapter module.
The adapter is designed to mechanically and electrically join the battery to the charger so that a highly compact system results. Electric means such as diodes and resistors ~3~ 60 BA 87 are carried by the adapter to transform the charger characteristics to khose useful for the 9 volt battery.
Thus, the usefulness of the charger is expanded to include 9 volt size batteries. The adapter in Serial No. 327,963 is a single molded housing having two folded portions interconnected by a hinge and ultrasonically bonded by means of integral energy concentrators.
The present invention is an improvement on the hinge-type adapter described in Serial No. 327,963.
The system of this invention uses an alternate method of securing the adapter in which the respective portions (leafs) of the adapter housing are provided with snappable gripping ~eans whereby the adapter can be closed into a unitary structure by snapping under pressure. This obviates the need for subsequent holding means such as ultrasonic welding, heat or solvent sealing, and the like.
Figure 1 is a plan view of an adapter of this invention in the open position;
Figure 2 is a cross-sectional view taken along line 2-2 in Figure l;
Figure 3 is a side elevation view of the adapter of Figure 2 in the assembled position;
Figure 4 is a plan view of another adapter of this invention in the open position;
Figure 5 is a cross-sectional view taken along line 5-5 in Figure 4; and Figure 6 is a side-elevation view of the adapter of Figure 4 in the assembled position.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will hereinafter be described in detail ~3Z~ 60 BA 87 two preferred embodiments of the invention and modifications thereto, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.
The overall charging system of which the present adapter forms an element is shown in Serial No. 327,963, and need not be repeated here to save unnecessarily detailed description.
Referring to Figure 3, adapter 2 is the bridging element between a charger and battery (not illustrated) and serves two functions; namely, physically attaching or mounting the battery and electrically connecting the terminals of the charger to the terminals of the battery.
To these ends, adapter 2 includes a pair of one-way f~male snap terminals 4, 6 attached to one surface of housing 8, see Figure 1, which interconnect with the charger terminals, and on an opposite surface a second set of one-way snap terminals, a male terminal 10 and female terminal 12, Figure 2, which interconnect with the battery terminals, respectively~ The one-way snap type terminal not only provides electrical contact but also mechanical gripping to support the battery on the charger.
Electrical circuitry is carried by the adapter to provide suitable conditioning of the source to battery characteristic by current and voltage controlO
To this end rectifying means particularly a half-wave rectifier 14, such as a diode, is connected between terminals 6 and 10 and a resistor 16 is connected between terminals 4 and 12. It will be appreciated by those skilled in the art that other arrangements of ~3Z:~L9~ ~
electrical components may also be utilized to provide suitable conditioning of the source to the battery.
Adapter housing 8 is preferably of a molded plastic construction. The adapter housing adapter housing shown in Figures 1-3 has a fully enclosed structure formed by a housing portion 2a and closure portion 2b. Portion 2a and 2b are integrally joined by a hinge 2c.
The outer surface of bottom portion 2b, Figure 2, carries charger terminals 10 and 12 and has a clearance area for receipt of a charger terrninal. The interior surface of portion 2a includes a molded pin with hook 20, which mates with and locks with a snapping action into aperture 22 when the adapter is folded about hinge 2c and the portions are pressed together.
The outer surface of top portion 2a, Figure 1 carries battery terrninals 4 and 6. After the terrninals, diode and resistor have been assembled t on the adapter to the open positions, Figures 1 and
