Abstract
A coil assembly is provided, comprising a coil former, a coil, and a connection block which is pivotally joined to the coil former. The coil is wound while the connection block is pivoted away, the winding wire ends are soldered to the terminal pins, and the connection block is pivoted close to the coil.
Claims7
A method for producing a coil assembly suitable for being installed in a relay and comprising an insulating coil former as a winding support, a coil having a coil end with winding wire ends and terminal pins for electrical connection to the coil, comprising the steps of:
- a) providing the insulating coil former which defines a coil axis and has a coil connection flange which includes:
- a first peripheral edge defining an axis which extends approximately in extension of the first peripheral edge,
- a second peripheral edge perpendicular to the first peripheral edge,
- an extension which is fixed to the second peripheral edge, and
- a connection block accommodating the terminal pins and being joined by a deformation section to the extension;
- b) winding a winding wire around the coil former to produce the coil, and leading out the winding wire ends close to the coil end at the coil connection flange;
- c) connecting the terminal pins to associated winding wire ends;
- and
- d) pivoting or twisting the connection block about said axis extending approximately in extension of the first peripheral edge of the coil connection flange into a final position overlapping the coil winding space, while said deformation section is permanently bent or permanently twisted.
A coil assembly, comprising:
- an insulating coil former as a winding support, which defines a coil axis and has a coil connection flange mounted on an axial end of the insulating coil former, the coil connection flange including:
- a first peripheral edge defining an axis which extends approximately in extension of the first peripheral edge,
- a second peripheral edge perpendicular to the first peripheral edge,
- an extension which is fixed to the second peripheral edge, and
- a connection block accommodating at least a first and a second terminal pin and being joint by a deformation section to the extension, and
- a coil wound around the coil former and having winding wire ends which are connected to the at least first and second terminal pins when the coil assembly is completed;
- wherein said deformation section between the connection block and the extension is a joining area that is permanently deformable by being bent or twisted from a preparatory position outside a coil winding space required for winding, and is to be pivoted or twisted into a final position overlapping the coil winding space when the winding has been completed.
