Terminal strip structure, connector device and its conductive terminal

A connector device, comprising:

• a base formed with a plurality of terminal receiving slots, each of the terminal receiving slots comprising a slot body, an engaging portion and a limiting slot, and the engaging portion and the limiting slot that are commonly disposed on one inner surface of the slot body;
• and
• a plurality of conductive terminals, each of the conductive terminals comprising:
• a main body disposed within the slot body and comprising at least one holding portion limiting the main body within the limiting slot, and a buckle portion engaged with the engaging portion;
• an elastic arm portion comprising a reversed folded portion, an abutment portion, a bending portion and a conductive portion, the reversed folded portion extending downward from a lower surface of the main body and extending upward after being folded, the abutment portion located between the reversed folded portion and the bending portion, arranged opposite to the main body, and physically contacted with another inner surface of the slot body, the bending portion protruding obliquely from the terminal receiving slot and connected to the abutment portion and the conductive portion, respectively;
• and
• a foot connecting portion protruding downwardly from one of the main body and the reversed folded portion to extend out of the terminal receiving slot, and further provided with a ball soldering member extending outwardly from the foot connecting portion for connecting to soldering balls.

A terminal strip structure, comprising:

• a material strip comprising a plate portion and a plurality of extension portions, the plate portion and the extension portions that are coplanar with each other, the extension portions arranged on a lateral side of the plate portion at intervals, and each of the extension portions protruding outwards from the plate portion, one end of each of the extension portions facing away from the plate portion is provided with a neck portion, and a thickness of the neck portion is smaller than a thickness of one of the extension portions;
• and
• a plurality of conductive terminals, each of the conductive terminals comprising a main body, an elastic arm portion and a foot connecting portion, an upper surface of the main body that is connected to the neck portion, and the main body comprising at least one holding portion and a buckle portion, and the elastic arm portion comprising a reversed folded portion, an abutment portion, a bending portion and a conductive portion, the reversed folded portion extending downward from a lower surface of the main body and extending upward after being folded, the abutment portion located between the reversed folded portion and the bending portion, and arranged opposite to the main body, the bending portion connected to the abutment portion and the conductive portion, respectively, and the foot connecting portion connected to one of the main body and the reversed folded portion, and the foot connecting portion further provided with a ball soldering member extending outwardly,
• wherein after the conductive terminals of the terminal strip structure respectively are inserted into a plurality of terminal receiving slots of a base, the material strip is completely separated from the conductive terminals by repeatedly swinging the material strip frontwards and backwards to break the neck portions.
