Definitions
- the invention relates to a bistable small relay high power, comprising a Isolierstoffgeophuse with a first housing chamber in which a single-phase contact assembly with two bus bars and a contact spring is arranged, wherein the contact spring is connected with one leg end fixed to one of the busbars and with its other free at least a movable contact bearing leg end operates on at least one fixed contact, which sits on the second busbar, and wherein in a second housing chamber, a bistable magnetic Aktorbauffle maybe arranged with a pivotable armature, which deflects the contact spring via a arranged in the housing output device to a circuit via to close or interrupt the busbars.
- Such a generic small relay is for example from the DE 10 2007 011 328 A1 known.
- the actuator assembly is disposed in a housing chamber above a housing chamber for the contact assembly, wherein both housing chambers have different dimensions.
- the actuator has a so-called H-armature, consisting of two parallel soft iron anchor plates, between which a permanent magnet is clamped, which is magnetized so that one pole is directed to the anchor plate and the other pole to the other anchor plate.
- the H-armature is mounted on a bolt in the housing chamber of the actuator and pivots depending on the excitation pulse of a umpolbaren magnetic coil between two mutually facing portions of two yoke parts of the magnetic circuit.
- the pin bearing causes friction.
- the H-anchor has a radially projecting arm, the one engages substantially stretched contact spring and deflects in this way.
- a miniature relay according to the preamble of claim 1 is in DE 101 62 585 C1 disclosed.
- the invention has for its object to develop a bipolar small electrical relay with a switching capacity in the range of 100 A or more that is easy to manufacture, easily adaptable in various configurations to predetermined conditions and uses a low switching energy.
- the relay according to the invention is exceptionally variable to configure for a variety of installation requirements. Due to the simple and automatic components and an appropriate division into an actuator and a contact assembly, the manufacturing costs are reduced. Further advantages are the small installation space with high switching capacity and the possibility of using the same components to minimize either the overall height or the width.
- the relay allows high switching cycles and is characterized by a low contact bounce, a very low contact resistance, a low own energy consumption, a low switching energy, a long life and a fast contact separation in the event of a short circuit.
- FIG. 1 shows a first embodiment of a bistable relay according to the invention with removed insulating material.
- the insulating housing consists of a square housing lower part 1 and a square housing cap 2, which enclose an actuator assembly 3 and a arranged next to the actuator assembly 3 contact assembly 4 between them.
- An intermediate wall 5 separates the lower housing part 1 into two approximately equal housing chambers 1 a, 1 b.
- One chamber 1 a, the actuator assembly 3 receives a positive fit, and the other chamber receives the contact assembly 4 form-fitting, including unspecified inner housing contours serve in Isolierstoffgeophuse.
- the actuator assembly 3 actuates via a the chambers 1 a, 1 b comprehensive output device, the contact assembly 4.
- the relay may be part of a smart electronic electricity meter.
- FIG. 2 shows the same version of a relay again with removed insulating material, the actuator assembly 3, the contact assembly 4 and the output device for better visualization of details are shown separated from each other.
- the output device is designed in the relay embodiment shown as mounted in the insulating housing rotatable two-armed rocker element 6.
- a bore 9 is provided for the storage of the rocker element 6 is in the middle of the partition 5 of the housing chambers 1 a, 1 b in the lower housing part 1, a bore 9 is provided.
- a gripper arm 6a the rocker element 6 engages a force application element 10 of a rocker armature 11 of the actuator assembly 3 and with the other gripper arm 6b a force application element 12 a contact spring 13 of the contact assembly 4.
- Both gripper arms 6a, 6b are equal, resulting in the same force-displacement ratios , But there are also other leverage ratios possible.
- an actuator assembly 3 is detailed in an exploded view.
- a U-shaped yoke 14 is stamped with its two yoke legs in one piece from soft iron sheet and bent.
- a flat permanent magnet 15 is arranged, which in turn carries a soft iron middle leg 16. In this way, results in an E-shaped magnetic core.
- On the outer yoke legs sit separately controllable excitation windings 17, which are supported by an insulating body 18.
- the insulating body 18 of the excitation windings 17 are connected by means of one or more film hinges 19 and can be wound in one operation, taking out the inner coil ends.
- the inner coil ends are soldered to one of the three pins 7, the outer separated to the other two pins 7.
- FIG. 4 the actuator assembly 3 is again shown in the assembled state, and as in all other drawings, the same reference numerals are used for functionally identical components. Evident is the particularly flat design of the actuator assembly and the small number of components.
- the Aktorbauffle 3 is controlled via the pins 7 according to a preferred variant so that for switching the rocker armature 11 from one switching position to the other of the permanent magnetic holding flux through the rocker arm 11 each closed parallel magnetic circuit at one of the exciter winding 17 of this magnetic circuit generated electromagnetic Control flux commutated with a direction opposite to the permanent magnetic holding flux direction in the other parallel magnetic circuit which carries the unexcited field winding 17. It is therefore each driven to switch the excitation winding 17, which sits in the magnetic circuit with the attracted armature wing of the rocker armature 11. This reduces the drive energy.
- FIG. 5 shows a variant of the contact assembly in an exploded view. Shown are three layers of a U-shaped contact spring 13. The three layers of different lengths are only mechanically and electrically connected at their ends. The shorter U-legs are attached with their ends to one of the busbars 8a, the longer ends carry a movable contact 20 which cooperates with a fixed contact 21 on the other busbar 8b. At the free ends of the upper and lower contact spring position force application elements 12 are formed in the form of cut-out resilient tongues, which serve for the attack of a driven device. Unspecified formations in the busbars 8a, 8b engage in corresponding formations in the housing chamber 1b of the lower housing part 1 for a positive connection. In addition, both ends of the bus bars 8a, 8b are designed for the connection of conductors.
- FIG. 6 is a contact assembly 4 drawn again in the assembled state.
- the U-shaped shape of the contact spring 13 can be achieved in spite of a short length and high required current carrying capacity well matched to the actuator force-displacement curve.
- This requirement is supported by the multi-layered contact spring 13, wherein it is advantageous for a heat dissipation, a length compensation of manufacturing tolerances, a length compensation in temperature expansion of the layers and the flexibility of the contact spring 13, if in the U-bending zone, the individual layers fanned self-aligning , It can also be provided that the individual layers have different suspension and conductivity properties.

With two contacts for a switching pole of the contact resistance between the contacts 20, 21 is halved, which has a favorable effect on the heating, the own energy consumption and the life of the contact system.
- the multi-layer contact spring 13 is slotted at its end bearing contacts, so that each of the two movable contacts 20 is resiliently movable for itself and can compensate for any manufacturing tolerances to the fixed contacts 21.
- the bounce and thus the contact erosion decreases.
- the dimensions of the two housing chambers 1 a, 1 b have not compared to the dimensions FIG. 1 changed.
- the two-armed rocker element 6 is mounted as a driven device.

- These movable contacts 20 cooperate with fixed contacts 21 on the second busbar 8b are mounted.
- the contacts 20, 21 are in contrast to the previous ones Contact assemblies on the other switching side, which faces away from the U-bend.
