When coil was unicoil, the coil lead pin only played effects such as supporting in the course of processing, location; When coil was twin coil, the function of two pairs of coil lead pin was identical.
The insulating material of insulating bobbin can fuse, and wrapped with insulation has been lived the remainder except that C shape magnetic conductor two pole-faces.
Insulating bobbin can comprise two parts at least, wrapped the part of C shape magnetic conductor two pole-faces belows respectively, be that C shape magnetic conductor has two pole-faces and is not insulated the middle part that material wraps, but scribble an insulating barrier on the surface of C shape magnetic conductor, also can be with another insulating material it to be wrapped at the middle part of C shape magnetic conductor.
On same framework, made by a conducting metal billot punching press by this framework before coiling for terminal pin, but this metal billot punching press is made a series of frameworks and they are linked together.Framework is cut off after C shape magnetic conductor and terminal pin integral molded plastic get bobbin, thereby obtains being no less than two terminal pin; Or terminal pin is part independently, and plug-in mounting is gone in the bobbin of injection formed.
The lead-out mode of coil is two of coil or four exits to be wrapped in leading foot respectively twine on the head end, then welds them together.
The utility model can be applicable on the electromagnetic relay, and electromagnetic relay comprises case, armature assembly, coil component and quiet spring are injection-moulded in together contact base component.Coil component comprises the magnetic conductor of the C shape that is injection-moulded in together and the bobbin of insulation, be wound with coil on the bobbin, armature assembly comprises armature, magnet steel and is arranged at least one movable contact spring of armature side and they are injection-moulded in together insulating material, coil component also comprises the terminal pin that is injection-moulded in together, terminal pin has two free ends, one end is the coil leading foot of relay, and the other end is the head end that twines of coil.
Compared with prior art, advantage of the present utility model is that the coil leading foot that coil of the prior art is twined head end and relay is arranged to incorporate terminal pin, and it is injection-moulded in the bobbin parts, omitted the production process that lead wire and leading foot is welded together with extras, significantly saved the input cost of equipment, eliminated the rosin joint hidden danger that may exist, simplified the relay production technology greatly, improved the coiling space of coil simultaneously, improved the magnetic efficiency of coil, simplify the technique for coiling of coil, thereby make the further miniaturization of relay, reduce the material cost of product, improved the functional reliability of relay again effectively, production efficiency and qualification rate help large-scale production line operation.
