Abstract:
The component, especially a relay or other electromechanical component, presents a parallelipedic shaped housing (1) on whose outer sides jut-outs are formed in the shape of ribs (4) or neps. In this way impact loads upon handling of the component are intercepted up to a predetermined size above which they are detected externally by damage to the jut-outs (4). This prevents components with invisible pre-deterioration from being installed and subsequently breaking down.
Abstract:
A relay has a first housing part (1), in which a coil (3) with a U-shaped core (6) is embedded, and a second housing part (2), in which at least one spring carrier (21) and at least one matching contact element (22, 23) are anchored. A contact spring (4) with a flat armature (5) is secured to the spring carrier. The relay is adjusted and at the same time sealed when the two shell halves (1, 2) are joined.
Abstract:
A hybrid relay has an electromagnetic relay system with at least one coil (65), a core-yoke unit (1) and at least one contact-switching armature (2), as well as a power semiconductor (5) whose switching section co-operates with the contacts to switch the load circuit of the relay. A delayed control of the power semiconductor (5) allows the contacts to be switched without load. The power semiconductor is in thermal contact with the core-yoke unit (1). A good heat dissipation and a compact design with few component parts are thus obtained.
Abstract:
The coil proposed has a main body with a substantially cylindrical tube (2) used as the support for the winding (5). Located on the external surface of the tube are stud-like protuberances (8) which project into the winding (5) and prevent the winding from shifting rotationally or longitudinally if it shrinks.
Abstract:
A relay has two axially aligned coils arranged on a base body (1) and provided each with a winding (23, 33) and a core (14, 15) interconnected by a U-shaped yoke (12). Between the inner ends of both cores (14, 15) a single armature (13) is mounted on a middle section of the yoke (12) in a switchable manner. In addition, two contact springs (7, 8) are arranged on both sides of the yoke, parallel thereto, between both coils. The contact-making ends of both contact springs lie in the resting state on a common middle contact element (61). When one or the other winding (23 or 33) is excited, one of the contact springs (7 or 8) is lifted off the middle contact element (61) and contacts an outer contact element (51 or 52). This relay is particulary suitable as a pole reversing relay for controlling direct-current motors with variable direction of rotation and can thus be preferably used in motor vehicles.
Abstract:
A relay is composed of two shell halves produced by injection-moulding plastics around the functional elements. A first shell half (1) is formed by injection-moulding plastics around a coil (3) with a U-shaped core (6), whereas the second shell half (2) is formed by injecting plastics around a spring carrier (21) and at least one fixed contact element (22, 23). A contact spring (4) is secured to the spring carrier with a flat armature. The relay is adjusted and at the same time sealed when the two shell halves (1, 2) are joined.
Abstract:
The relay has at least one switching system with a basic body (1) forming a base plate (11) in which a contact spring connector (4) and counter-contacts (5, 6) are secured and on which a coil (21, 22) with a core (23) and a yoke (24) is arranged upright perpendicular to the base plate and there is an armature between the coil and the base plate. There is a U-shaped contact spring (3) secured to the armature (26) and the two spring arms thus formed form a connecting arm (31) and a highly conductive contact arm (32). The relay can be easily made with simple components as a single and also a double or multiple relay.
Abstract:
The relay disclosed has a leaf spring (9) which acts as a contact spring and armature-reset spring and which has two arms disposed approximately at right angles to each other. The end of the first arm is suspended from a pin (6c) on the return pole piece (6) so that it can turn freely about the point of suspension. In addition, the cross-section of this first arm is reduced so that it is mainly loaded in tension, the armature reset force being provided substantially by the second arm (9b) of the spring. By means of a support element located between the return pole piece (6) and the first arm (9a) of the spring, the latter is biased slightly outwards, however, so that it exerts a small directive force on the armature (7) in order to draw the armature in predetermined fashion into its bearing. Owing to the difference in cross-section, however, this force has virtually no effect on armature resetting.
Abstract:
The invention relates to a changeover switch for changing between two current paths (1, 2; 3, 4) of a DC circuit that comprises in every current path a bridge contact system (110, 120; 230, 240) with two contact paths (111, 112; 121, 122; 131, 132; 141, 142) and one bridge conductor (113; 123; 133; 143). Said bridge conductors of the two current paths (1, 2; 3, 4) that are alternatively closed are insulated from one another while they are actuated by a common solenoid system (EM1, EM2). The inventive changeover switch is advantageously used as a polarity reverser in a so-called H-bridge circuit for motor drives with alternating sense of rotation.
Abstract:
A circumferential sealing ring (14) is cast in one piece by the two-component injection moulding process on the dimensionally stable plastic of one part (11) to seal the plug-in region between a relay (1) and a plug base (2). The sealing ring (14) is elastically deformed by mutually engaging elements (15, 26), thus providing the desired seal in the arrangement.
