Integrated positioning and locking device

An assembly for installing onto a chassis, comprising

• an external wall;
• and
• at least one integrated positioning and locking device for installing said assembly onto said chassis, said integrated positioning and locking device comprising:
• a latch formed in said external wall for latching against said chassis, wherein said latch includes a lip which points externally from said external wall;
• an inner wall for blocking access through said external wall to an internal region of said assembly when said assembly is in an installed position on said chassis;
• and
• a T-shaped boss integrated into said inner wall for positioning said assembly relative to said chassis to facilitate placing said latch into a latched position for locking said assembly in said installed position, wherein said T-shaped boss includes a leading end which guides said assembly into said installed position, is spherically shaped, and is higher than said inner wall and said latch.

A system comprising:

• a chassis including a positioning hole and a latching hole;
• and
• an assembly in an installed position on said chassis, said assembly comprising an external wall and at least one integrated positioning and locking device for installing said assembly onto said chassis, said integrated positioning and locking device comprising:
• a latch formed in said external wall for latching against said chassis through said latching hole, wherein said latch includes a lip which points externally from said external wall;
• an inner wall for blocking access through said external wall to an internal region of said assembly;
• and
• a T-shaped boss integrated into said inner wall for positioning said assembly relative to said chassis to facilitate placing said latch into a latched position for locking said assembly in said installed position, wherein said T-shaped boss includes a leading end which guides said assembly into said installed position by being inserted into said positioning hole, is spherically shaped, and is higher than said inner wall and said latch.

A method of installing an assembly onto a chassis, said method comprising:

• aligning a T-shaped boss of said assembly with a positioning hole of said chassis;
• inserting a leading end of said T-shaped boss into said positioning hole by pressing said assembly onto said chassis;
• depressing a latch of said assembly to enable a lip of said latch to be inserted through a latching hole of said chassis;
• and
• releasing said latch such that said lip latches against said chassis and locks said assembly to said chassis.
