Pluggable connecting device for contactors and a contactor

A pluggable connecting device for connecting to a coil of a contactor that comprises a housing having a top electrode plate and a coil framework in the housing, the coil framework comprising an annular column around which a coil is wound and having an opening facing the top electrode plate and first and second connecting sheets on a surface of the coil framework on opposite sides of the opening facing the top electrode plate, the connecting device comprising:

• an insulated connecting member;
• and
• a first conductive element and a second conductive element fixedly connected to respective ends of the insulated connecting member, wherein the first conductive element has an insertion end and a wiring end at opposite ends thereof, wherein the second conductive element has an insertion end and a wiring end at opposite ends thereof, wherein the insertion end of the first conductive element and the insertion end of the second conductive element are configured to be inserted into the housing through respective first and second openings in the top electrode plate to connect to the first connecting sheet and the second connecting sheet, respectively, wherein the wiring end of the first conductive element is provided with a bending part, wherein the wiring end of the second conductive element is provided with a bending part, and wherein the bending part of the first conductive element and the bending part of the second conductive element extend in a direction getting close to each other.

A contactor comprising:

• a housing comprising an electrode top plate and a mounting bottom plate which are arranged oppositely, the electrode top plate being provided with a first expansion hole and a second expansion hole;
• and
• a coil framework located inside the housing, the coil framework comprising an annular column around which a coil is wound and having an opening facing the top electrode plate and a first connecting sheet and a second connecting sheet on the annular column on opposite sides of the opening and facing the top electrode plate and having contacts aligned with the first expansion hole and the second expansion hole, respectively, such that first and second conductive elements inserted in respective ones of the first and second expansion holes are electrically connected to the first connecting sheet and the second connecting sheet, respectively, wherein the coil framework comprises a framework body, a first fixing part and a second fixing part which are fixed on an end face of the framework body, wherein the first connecting sheet and the second connecting sheet are respectively fixed in the first fixing part and the second fixing part, wherein the first connecting sheet and the first fixing part are respectively provided with a first through hole and a first auxiliary hole which are aligned with the first expansion hole, and wherein the second connecting sheet and the second fixing part are respectively provided with a second through hole and a second auxiliary hole which are aligned with the second expansion hole.
