Abstract
The relay has a T-shaped core and a U-shaped armature, the transverse web of the latter being mounted on the free end section of the core longitudinal limb, and the free ends of its longitudinal arms forming two parallel operating air gaps with respect to the transverse limbs of the core. In this way, particularly simple assembly and an operating air gap with large pole areas can be achieved using a small number of simple parts.
Claims10
Electromagnetic relay having
- a coil winding which is arranged on a coil former between first and second coil flanges,
- a T-shaped core having a longitudinal limb and two transverse limbs, the longitudinal limb extending axially through the coil former,
- a U-shaped armature having two longitudinal arms, which run on both sides of the coil, and a transverse web at a first end section of the armature being mounted in the region of the first coil flange on an end section of the core, and a second end section forming an operating air gap with the core in the region of the second coil flange, and
- a contact arrangement having at least one stationary contact element and at least one moving contact spring, the moving contact spring being operable by the armature via an operating device which can be moved transversely with respect to the coil axis, the improvement comprising the armature being mounted at the transverse web on the free end section of the longitudinal limb of the core, and the free ends of the armature longitudinal arms form two parallel operating air gaps with free ends of the core transverse limbs.
