Housing for cigarette lighter adapter or accessory adapter plug
View Patent ↗A housing for a Cigarette Lighter Adapter (CLA) or accessory adapter plug facilitates insertion of the plug into a CLA or accessory adapter receptacle. In one embodiment of the invention, the housing is formed in a generally cylindrical shape with an expanded diameter portion defining a gripping portion which facilitates the gripping of the device. The housing may be used to house circuitry for a battery charger and include an indicator light to indicate the state of charge of the battery being charged.
1. A housing for a cigarette lighter adapter (CLA) or accessory adapter plug, the housing comprising:
a first housing and a second housing, said first and second housing portions being generally symmetrical with respect to a longitudinal axis of said housing and forming a generally cylindrical shape when said first housing portion and said second housing portion are assembled together defining opposing ends and an intermediate portion formed intermediate said opposing ends, said housing having a generally cylindrically cross-section defining a diameter that varies along the longitudinal axis of said housing, said intermediate portion having generally larger diameters than said opposing ends defining a compartment for receiving an electronic circuit and forming a gripping portion for gripping said housing.
2. The housing as recited in claim 1 , wherein said housing defines a length and said housing halves are generally symmetrical with respect to the axial length of said housing.
3. The housing as recited in claim 1 , wherein said intermediate portion includes a cross sectional area that is generally larger than the cross sectional area of both of said opposing ends.
4. The housing as recited in claim 3 , wherein cross sectional area defined by said intermediate portion is generally circular.
5. The housing as recited in claim 3 , wherein said cross sectional defined by said intermediate portion varies.
