LIQUID DISCHARGE HEAD, LIQUID DISCHARGE UNIT, AND LIQUID DISCHARGE DEVICE

To provide a liquid discharge head which enables reduction of assembly work hours needed for fixture of a connector substrate to achieve good assemblability.SOLUTION: A liquid discharge head 10 discharges a liquid and includes: a cover member 3 which covers at least a part of the liquid discharge head; a connector substrate 2 provided with a connector 2a with which a wiring member is detachably attached and having a first engagement part 52 which engages with the cover member 3; an opening 61 which exposes at least a part of the connector 2a while engaging with the connector 2a or the connector substrate 2; and a cap member 1 having a second engagement part 41 which engages with the cover member 3 and detachably attached to the cover member 3. An engagement direction between the cover member 3 and the connector substrate 2 intersects with an engagement direction between the cap member 1 and the connector 2a or the connector substrate 2.SELECTED DRAWING: Figure 1 【課題】コネクタ基板の固定に要する組立工数が削減され、組立性が良好な液体吐出ヘッドを提供する。【解決手段】液体を吐出する液体吐出ヘッド１０であって、液体吐出ヘッドの少なくとも一部を覆うカバー部材３と、配線部材が着脱可能に接続されるコネクタ２ａが設けられ、カバー部材３と係合する第１係合部５２を有するコネクタ基板２と、コネクタ２ａまたはコネクタ基板２と係合しつつコネクタ２ａの少なくとも一部を露出させる開口部６１と、カバー部材３と係合する第２係合部４１を有し、カバー部材３に着脱可能に装着されるキャップ部材１と、を備え、カバー部材３とコネクタ基板２との係合方向は、キャップ部材１とコネクタ２ａまたはコネクタ基板２との係合方向と交差する。【選択図】図１
