Process and apparatus for locating light emitting diode in a hand tool head assembly

摘要

A motorized hand tool, such as a cordless ratchet wrench, is configured for reducing part count and reducing assembly processes. The motorized hand tool includes an overmolded window for a light emitting diode (LED) in a clamshell housing. An LED is secured within the clamshell housing by conductors extending from the LED that are encapsulated in rigid sleeves. The rigid sleeves provide a friction fit in a channel between fingers molded in the clamshell housing. A switch assembly of the motorized hand tool is mounted in the clamshell housing and covers channel to contains the conductors and sleeves. By containment of the rigid sleeves and conductors, the LED is located securely in the overmolded window.

主权项

1. A motorized hand tool apparatus, comprising:
an internal component; a clamshell housing assembled around the internal component; a window extending through the clamshell housing; a window boss extending at least partially around the window within the clamshell housing; a set of fingers extending from the window boss and defining a set of channels between the clamshell housing and the internal component, a light emitting diode (LED) partially enclosed within the clamshell housing by the window; a set of conductors extending from the LED; and a set of rigid sleeves each encapsulating a respective one of the conductors, each of the rigid sleeves retained in a respective one of the channels by a friction fit with the fingers.
