Abstract

The invention provides a quick disconnect device for use between image insifier tubes and their power supply or their supporting apparatus.

Claims

1. An image intensifier which converts a low light light level (invisible) image to a visible image comprising:

a support member including;

an electrical power source attached to said support member having at least one electrical terminal,

a female bayonet socket, also attached to said support member, and

at least one resilient electrical contact mounted in said socket connected to said one terminal,

an optical unit mated to said female socket including;

an electrical image intensifier tube,

a lens means mounted on said tube to focus at least the invisible image in said intensifier tube,

a male bayonet member complimentary in shape and mated with said female member rigidily attached to said tube and lens means, and

a rigid electrical contact mounted on said male member oriented to press on said resilient contact as said male and female members are mated.

2. An image intensifier according to claim 1 wherein said power source comprises a battery holder and a battery.

3. An image intensifier according to claim 1 wherein said support member further includes;

an assembly head frame attached thereto;

said power source is rigidly attached to said frame; and

said female socket being slideably attached to said frame for adjustment of the interpupillary distance.

4. An image intensifier according to claim 1 wherein:

said male member includes an external portion when mated with said female member;

a spring loaded release button is mounted in said external portion and projecting therefrom;

a detent recess is formed in said female member close to said external portion in the mated position;

a slideably mounted detent button mounted in said male member positioned to engage said detent recess in the mated position; and

a stiff spring member couples said release button and said detent button.
