Drive coil device

A drive coil device, in particular for an oscillating armature pump, with at least one coil carrier, with at least one coil wire that is wound onto the coil carrier to form a coil, and with at least one coil enclosure configured to at least partly enclose the coil,

• wherein the coil enclosure comprises at least one contact interface which is configured to receive at least an end of the coil wire,
• wherein
• the coil enclosure comprises at least one wall which is connected to the coil carrier in at least one of a form-fitting and a force-fitting manner,
• wherein the coil is free of a sealing overmolding,
• wherein the wall is realized in a grid-like manner,
• wherein the contact interface comprises at least one insulation-displacement connector which is configured to electrically contact the coil wire via an insulation-displacement contact,
• wherein the insulation displacement connector comprises at least one contact point, in particular a plug contact, for attaching an electrical feed line,
• wherein the coil enclosure comprises at least one holder for accommodating a thermal fuse, which is configured to arrange the thermal fuse in a proximity of the coil,
• wherein the coil enclosure comprises at least two further contact interfaces, wherein a first contact interface of the further contact interfaces is configured to contact a second end of the coil wire by means of an insulation-displacement connector and to contact a first connection contact of a power diode or of the thermal fuse by means of an insulation displacement connector, and
• a second contact interface of the further contact interfaces is configured to contact a second connection contact of the thermal fuse by means of a further insulation-displacement connector.
