Flexible printed circuit connector
View Patent ↗A flexible printed circuit connector structure and assembly method. A panel with a back side that is parallel to a first plane and a flexible printed circuit backer that has a base and a backing structure. The base is attached to the back side of the panel. The backing structure depends from the base and extends along a second plane that forms an angle with the first plane. A first flexible circuit side of the flexible printed circuit is attached to a first side and an opposite second side of the backing structure. The flexible printed circuit has exposed conductors on a second flexible circuit side that is opposite the first flexible circuit side.
1. A flexible printed circuit connector structure; comprising:
a panel having a back side that is parallel to a first plane, the panel configured to be mounted into a panel mounting location of a device body;
a flexible printed circuit backer comprising a base and a backing structure,
the base attached directly to the back side;
the backing structure depending from the base at a location under the panel, and the backing structure extending along a second plane that forms an angle with the first plane, the backing structure having a first side and a second side that are parallel with the second plane, the second side being opposite the first side; and
a flexible printed circuit having a first flexible circuit side and a second flexible circuit side, the second flexible circuit side being opposite the first flexible circuit side, the flexible printed circuit lying along the first side and the second side, the first flexible circuit side being attached to the first side and the second side, the flexible printed circuit having exposed conductors on the second flexible circuit side opposite the first side, the flexible printed circuit further bending away from the flexible printed circuit backer and wherein the first flexible circuit side is attached to the back side at locations away from the flexible printed circuit backer.
2. The flexible printed circuit connector structure of claim 1 , wherein the flexible printed circuit backer comprises stainless steel.
3. The flexible printed circuit connector structure of claim 1 ,
wherein the panel is transparent, and
the flexible printed circuit connector structure further comprising a touch sensor mounted to the back side,
the touch sensor extending along the first plane and configured to sense touching of the panel on a side opposite the back side.
4. A flexible printed circuit connector structure comprising:
a panel having a back side that is parallel to a first plane;
a flexible printed circuit backer comprising a base and a backing structure,
the base attached to the back side;
the backing structure depending from the base and extending along a second plane that forms an angle with the first plane, the backing structure having a first side and a second side, the second side being opposite the first side; and
a flexible printed circuit having a first flexible circuit side and a second flexible circuit side, the second flexible circuit side being opposite the first flexible circuit side, the flexible printed circuit lying along the first side and the second side, the first flexible circuit side being attached to the first side and the second side, the flexible printed circuit having exposed conductors on the second flexible circuit side opposite the first flexible circuit side;
a receiving structure comprising a panel mounting location, the panel being removeably mounted to the panel mounting location,
the receiving structure comprising at least one yieldable electrode,
each yieldable electrode being brought into contact with the flexible printed circuit when the panel is mounted to the panel mounting location,
each yieldable electrode urging the flexible printed circuit into the first side when the panel is mounted to the panel mounting location, and
each yieldable electrode forming a conductive path with a respective exposed corresponding conductor on the first flexible circuit side when the panel is mounted to the panel mounting location.
5. The flexible printed circuit connector structure of claim 4 ,
the panel mounting location defining an opening, and
wherein the backing structure extends through the opening.
6. The flexible printed circuit connector structure of claim 4 , wherein the receiving structure further comprises a fixing block,
the fixing block having a surface extending parallel to the second plane and separated from the second side by a first distance when the panel is mounted to the panel mounting location.
7. The flexible printed circuit connector structure of claim 6 , wherein the flexible printed circuit has a thickness that is one of equal to and greater than the first distance, and
wherein a portion of the flexible printed circuit extends between the second side and the fixing block.
