Abstract

A battery-charger with adjustable contacts which are specifically arranged according to specific positions of power contacts of different types of batteries. The battery-charger includes a base body on which a battery to be charged is placed, a contact-adjusting member disposed on the base body and a set of conductive contacts fitted in the contact-adjusting member in accordance with the positions of power contacts of the battery. After a set of contacts are specifically fitted in the contact-adjusting member, the contact-adjusting member is fitted on the base body. Thereafter, the battery to be charged is fixedly located on the base body and adjacent to the contact-adjusting member. At this time, the specifically arranged contacts contact with the power contacts of the battery and conduct electricity to the battery.

Claims

1. A battery-charger for different size batteries comprising,

a base body,

a contact-adjusting member disposed on said base body and a set of conductive contacts moveably engaged to said contact-adjusting member,

wherein said base body has a battery fixing seat on which said different size batteries are located and a fixing member on which said contact-adjusting member can be releasably engaged,

said fixing member being formed with two lateral insert grooves and a resilient fixing plate for resiliently abutting against and releasably fixing said contact-adjusting member on said fixing member,

said contact-adjusting member having two plane surfaces perpendicular to each other,

each of said two plane surfaces formed with more than two through holes,

said set of conductive contacts being movable for insertion into any of said through holes according to specific positions of power contacts on a battery of said different size batteries,

said contact-adjusting member also having two lateral insert sections corresponding to said insert grooves of said fixing member of said base body,

whereby said contact-adjusting member is engaged on said fixing member by means of inserting said insert sections in said insert grooves,

said set of contacts being used to conduct electricity supplied by an inner circuit of said base body to said battery for charging the battery,

each conductive contact of said set of conductive contacts being composed of a cover section and a conductive contact section,

wherein said cover section is held in engagement between said contact-adjusting member and said fixing member while said conductive contact section extends through a through hole of said more than two through holes to engage a power contact of said power contacts on said battery when said contact-adjusting member is engaged to said fixing member, and

a wire being used to electrically connect said conductive contact section with said inner circuit of said base body.
