A thermal head includes a substrate; a plurality of heating elements disposed on the substrate; a plurality of electrodes disposed on the substrate and electrically connected to the plurality of heating elements; a connector disposed adjacent to the substrate and including a plurality of connector pins including connection portions, each of which is electrically connected to a corresponding one of the plurality of electrodes, and a housing containing the plurality of connector pins; and a covering member covering the connection portions on the substrate. The housing includes an opening facing away from the substrate. The covering member includes a first portion located on the substrate and a second portion located on the housing. The second portion includes a first protrusion protruding toward the opening in a plan view.

Thermal head and thermal printer

A thermal head includes a substrate; a heat generating section disposed on the substrate; an electrode which is disposed on the substrate and is electrically connected to the heat generating section; and a connector including a fixing ping electrically connected to the electrode, a movable pin which holds the substrate between the movable pin and the fixing pin, and a connection pin which connects the fixing pin and the movable pin. The movable pin includes a movable section which is bent or curved and a contact section making contact with the substrate. The movable pin is disposed so as to protrude from the connection pin beyond the fixing pin. The contact section is located closer to a connection pin side than a tip end of the fixing pin.

A thermal head includes a substrate; a plurality of heating elements; a plurality of electrodes; a first covering layer; and a covering member. The thermal head further includes a second covering layer extending from the first covering layer onto the end surface. The housing is in contact with the second covering layer.

A thermal head capable of reducing a possibility of separation of a connector is provided. A thermal head includes a substrate; a plurality of heat generating portions disposed on the substrate; a plurality of electrodes which are disposed on the substrate and are electrically connected to the plurality of heat generating portions, respectively; and a connector including a plurality of connector pins which pinch the substrate and are electrically connected to the plurality of electrodes, respectively, and a housing for containing the plurality of connector pins. The housing is disposed adjacent to the substrate in a sub-scanning direction, and the housing includes a support portion disposed under the substrate. This can reduce a possibility of separation of the connector.
