Optical navigation module with alignment features

摘要

An optical navigation module comprising a rigid flange having a top surface. An optical navigation unit can be coupled to the top surface of the rigid flange with an electrical connection electrically coupled to the optical navigation unit. An alignment flange can be coupled to the rigid flange with the alignment feature including one or more alignment features. The alignment feature can be a hole adapted to receive an alignment pin to hold and align the optical navigation module.

主权项

1. An optical navigation module, comprising:
a rigid flange having a top surface; an optical navigation unit coupled to the top surface of the rigid flange, the optical navigation unit including a contact surface and being configured to detect direct contact of the contact surface by an external object; an electrical connection electrically coupled to the optical navigation unit; and an alignment flange coupled to the rigid flange, the alignment flange including:
a center portion;an outer portion that surrounds the center portion, the outer portion having a thicker dimension than the center portion, the center portion being configured to deflect to provide an actuation force and generate an electrical signal in response to pressure applied to the optical navigation unit; andat least one alignment feature.
