Abstract
There are provided a liquid ejecting head having a high fabrication efficiency and a high reliability of an electric connector, and a fabricating method for the liquid ejecting head. A direction in which a channel forming member is incorporated to a casing crosses a direction in which a flat spring is resiliently deformed. In incorporating the channel forming member, an abutment portion formed at the flat spring is allowed to abut on the casing, thus deforming the flat spring. The flat spring is brought into contact with an inside contact pad by a resilient restoring force of the flat spring.
Claims17
A liquid ejecting head comprising:
- a main body provided with an ejecting portion capable of ejecting liquid supplied through a liquid channel and an electric contact portion;
- a channel forming member that is connected to the main body in a first direction so as to form the liquid channel;
- and
- a conductive flat spring that is fixed to the channel forming member and is brought into contact with the electric contact portion by a resilient restoring force in a case where the flat spring is deformed in a second direction crossing the first direction,
- wherein the flat spring is provided with an abutment portion that abuts on the main body so as to resiliently deform the flat spring in the second direction in a case where the channel forming member is connected to the main body in the first direction, and
- the flat spring includes a plurality of bent portions whose bend angles are changed in a case where the flat spring is resiliently deformed in the second direction.
