NOVELTY - An electrical component protection device (10) comprises a protective housing having a base (12) with a contact hole for receiving an electrical terminal pin (49), and having a projecting shoulder extending from the base to a first distance from the base, the shoulder including a rib, and having a retaining clip (22) extending from the base to a second distance from the base, the second distance being greater than the first distance.    USE - For an electrical power-providing unit (claimed).    ADVANTAGE - The assembly permits but does not require the use of adhesive material, when assembling the battery and an electrical component; and permits replacement of an improperly operating electrical component.    DETAILED DESCRIPTION - An electrical component protection device comprises:    (1) a protective housing having a base with a contact hole for receiving an electrical terminal pin, and having a projecting shoulder extending from the base to a first distance from the base, the shoulder including a rib, and having a retaining clip extending from the base to a second distance from the base, the second distance being greater than the first distance; and    (2) a terminal cap (28) having two sides (31, 34), where in use, at least part of the first side of the terminal cap is prevented from moving beyond the projecting shoulder, and at least part of the second side of the terminal cap is restrained by the retaining clip, permitting the electrical component to reside between and be protected by the housing and the terminal cap.    An INDEPENDENT CLAIM is also included for an electrical power-providing unit, comprising:    (1) a battery having a terminal pin;    (2) an electrical component electrically connected to a battery;    (3) an electrical component protection device; and    (4) an adhesive between the base and the battery.    DESCRIPTION OF DRAWING(S) - The figure is a partially cross sectional side view of protection device mounted on the header of a battery.
