Abstract
The assembly includes an electrically insulative support member which overlies electrical contacts on the handpiece and further includes a pair of contact members which press a flexible printed circuit against the electrical contacts to couple a pair of bulbs to the electrical power source. The light source assembly additionally includes means for effectively sealing the contact regions from environmental fluids.
Claims5
For use with an elongated dental handpiece having first connecting means at its proximal end for coupling the handpiece to a source of electrical power and having second connecting means generally axially spaced therefrom at its distal end for coupling the handpiece to a dental work tool and including an electrical conductor for electrically coupling the first connecting means to an exterior contact region adjacent the distal portion of the handpiece,
- an improved light source assembly comprising:
- an electrically insulative support member adapted to overlie the contact region of the handpiece,
- a pair of electrically conductive contact members protruding from the radially inward surface of the support member which is proximate to the handpiece so as to contact the contact region thereof,
- at least one bulb mounted on the radially outward surface of the support member and including first and second electrical leads,
- first and second receptacle members formed within the support member to respectively freely accept the first and second leads from the bulb
- a flexible printed circuit for securely coupling the contact members to respective receptacle member without interfering with the acceptance of the leads.
