Relay

Abstract

The invention relates to a relay (100) for assembling in terminal blocks with a reduced installation space, comprising: an electromagnetic drive assembly (101) which comprises an armature (103), an armature bearing spring (105), and a yoke (107), wherein the armature (103) is at least partly spaced from the yoke (107), is movably mounted, and is designed to reduce the distance between the yoke (107) and the armature (103) under the effect of an electromagnetic force acting on the armature (103). The armature bearing spring (105) is designed to apply a spring force to the armature (103), said spring force counteracting the electromagnetic force, and the yoke (107) is designed to interact electromagnetically with the armature in order to apply the electromagnetic force to the armature (103).The relay also comprises a contact spring (109) which has a first contact surface (111-1) and a contact arm (113), said contact arm (113) being arranged at a distance from the first contact surface (111-1) and being designed to come into contact with the first contact surface (111-1) by means of a pressure force acting on the contact arm (113) in order to establish an electric connection betweenthe first contact surface (111-1) and the contact arm (113), and an insulation element (115) which is arranged on the armature (103) and lies on the contact arm (113). The insulation element (115) isdesigned to electrically insulate the armature (103) from the contact arm (113) and to actuate the contact arm (113) in order to produce the pressure force which acts on the contact arm (113) by moving the armature (103). The armature (103), the insulation element (115), the contact arm (113), and the yoke (107) are each arranged parallel to a support plane (117), and the armature (103), the insulation element (115), and the contact arm (113) are mounted in an at least partly movable manner perpendicularly to the support plane (117).

Description

technical field [0001] The invention relates to a relay assembled in a junction box with a smaller installation space. Background technique [0002] The relay may contain electrical connection contacts which may have a minimum spacing in relation to the minimum insulation distance to be observed. The electrical connection contacts of a relay are usually arranged in a row according to said minimum insulation distances, and it may be necessary to prevent actual insulation distances from being smaller than such minimum insulation distances. Thus, by reducing the width perpendicular to the row of electrical connection contacts, it is possible to achieve a greater packing density of relays arranged next to each other, in particular in a junction box. Existing on-off devices in relays, for example, have a minimum width of 5 to 6mm, and can be used in junction boxes with a minimum box width of 6mm, so there are such relays that are not suitable for junction boxes with a width of 3...
