Printhead assembly with electrical connection arrangement
View Patent ↗A printhead assembly includes an elongate printhead mounted along a spine. A conductive film is provided in electrical contact along the printhead. Power and data from a flexible circuit bearer are conveyed to the conductive film, and hence the printhead, by pressing the flexible circuit bearer against the film. The flexible circuit bearer is forced against the film by an angled member arranged to bias the flexible circuit bearer towards the spine thereby pressing the intermediately located flexible circuit bearer into abutment with the conductive film.
1. A printhead assembly including:
an elongate printhead located along a first surface of a spine;
a first conductive film in electrical contact along the printhead
a flexible circuit borer abutting the first film; and
an angled member braced against the first surface and cooperating wit a further surface of the spine to press the flexible circuit bearer into abutment with the first film;
wherein the spine, elongate printhead and angled member are mounted upon a support member; and
wherein the support member includes a wing portion upon which the flexible circuit bearer is mounted.
2. A printhead assembly according to claim 1 , including a casing cooperating with the spine to define a number of elongate ink feed conduits terebetween.
3. A printhead assembly according to claim 1 , wherein the first conductive film comprises a TAB film.
4. A printhead assembly according to claim 1 , wherein the flexible circuit borer comprises a flexible PCB.
5. A printhead assembly according to claim 4 , wherein the flexible circuit bearer supports busbars to provide power to the printhead.
6. A printhead assembly according to claim 1 , wherein an air gap is formed in the spine alongside the elongate printhead.
7. A printhead assembly according to claim 1 , wherein the support member houses, a printhead capping mechanism.
8. A printhead assembly according to claim 7 , wherein a portion of the support member and the angled member define a print media entry slot.
