Protection device for protecting an electrical component and method of assembling a battery with a protection device and an electrical component

An electrical power providing unit having a battery, an electrical component electrically connected to the battery, and a protection device for protecting the electrical component, the protection device comprising:

• a protective housing having a base with a contact hole therethrough for receiving a terminal pin of the battery, and having a projecting shoulder extending from the base to a first distance spaced from the base, and having a retaining clip extending from the base to a second distance spaced from the base, the second distance being greater than the first distance, wherein the electrical component is supported by the base;
• and
• a terminal cap having a first side and a second side, wherein at least part of the first side of the terminal cap contacts the projecting shoulder and at least part of the second side of the terminal cap contacts the retaining clip;
• wherein,
• the electrical component resides between the base and the terminal cap.

A method of assembling a battery and an electrical component, comprising:

• providing a battery having a terminal pin;
• providing a protective housing having a base with a contact hole therethrough, a projecting shoulder and a retaining clip;
• placing the protective housing on the battery so that the terminal pin extends into the contact hole;
• providing an electrical component on the base;
• electrically connecting the electrical component to the terminal pin;
• providing a terminal cap in contact with the projecting shoulder and the retaining clip;
• and
• connecting the terminal cap to the electrical component.
