Abstract
Improved automobile cigarette lighter male accessory adaptor plug and female receptacle connector assemblies are disclosed whereby a vehicle's electrical system is adapted to operate a variety of remote electrical devices and appliances. Both the male plug and female receptacle are constructed as unitary connector assemblies incorporating in-line fuse holders receptive of miniature, generally flat, insert type fuses having visable fuse links and extending blade terminals; the fuse being openingly accessible at the exterior of the connector assembly whereby the same is air cooled and is readily visable and removeable for inspection or replacement without disassembly of the connector.
Claims10
An electrical connector assembly comprising:
- positive circuit contact means, negative circuit contact means, a pair of electrical conductors of an electrical card, coupling means associated with each of said contact means for connecting each thereof in circuit with a respective one of said conductors;
- said coupling means associated with said positive contact means comprising a pair of separated, electrically isolated coplanar blade receptive terminal connector means, one of which is connected to said positive contact means and the other of which is connected to said one of said conductors associate with said positive contact means;
- one-piece insert-type fuse means having a pair of laterally coplanar spaced blade contacts interconnected by a visably encapsulated, electrically insulated fuse link, said blade contacts being insertable into said spaced terminal connector means to establish fused circuit connection between said positive contact means and its associated said one of said conductors;
- said coupling means associated with said negative contact means directly joining the same to its associated one of said conductors;
- integral cylindrical housing means for enclosing said contact means, conductors, coupling means and terminal connector means to provide a unitary assembly;
- said housing means being formed with a finger receptive exterior depression having an opening in the bottom thereof communicating with said terminal connector means and adapted to receive the blade contacts of said fuse means whereby the latter may be manually mounted in said terminal connector means so that said fuse link is visibly exposed on the exterior of said housing means.
