Definitions
- the invention relates to a relay for a defibrillator with a support base on which a coil and a by their electrical excitation via an armature and at least one further mechanical intermediate actuatable contactor are mounted with a contact arrangement which on separate (ie not in the open state electrically connected) contact carriers carried contacts which are connected by driving the coil with each other or removable from each other.
- a relay of this type is used inter alia in defibrillators to deliver an electrical pulse from a high voltage part via electrodes on the body of a patient, as set out in DE 102 54 482 B4.
- an exact timing of the pulse to detected signals of the heart activity is of essential importance. If z. B. in a measurement signal a QRST complex with a usual duration of about 15 ms based, within which a short so-called vulnerable phase for the shock delivery is considered, so may be caused by delays in the passage of the paths of movement of the contacts and also by bouncing the contacts and on the order of z. B. 10 to 15 ms, a defibrillation effect are significantly adversely affected. It can be z. For example, increased defibrillation energy may be required if the optimal time is not reached. Also, relays often have significant differences in quality and variations in the switching accuracy due to manufacturing tolerances.
- This relay has a first and second, with respect to the electromagnet fixedly arranged fixed contact, which are arranged on a stationary in an insulating base contact carrier. Furthermore, a correspondingly fixed in the socket third fixed contact may be present. In addition, two U-shaped contact carrier are present, each having a first and a second leg or a nen third and fourth leg, at the ends of contacts are arranged, which can be brought into an electrically conductive connection with the fixed contacts by means of a control member or at other control for disconnecting the electrical connection are removable.
- At least one intermediate element is designed as a rotary lever coupled to the armature, which is connected to one of the contacts (e.g. 1) bearing contact carrier is pivotally coupled, and that the other of the bearing contacts to be brought into contact with other contact carrier is pivotally coupled to another rotary lever or directly to the armature, wherein when contacting both contact carrier with the contacts to be contacted guided towards each other to be moved.
- the intermediate members have a coupled to the armature rotary lever assembly having at least two Drehhebein, one of which pivotally connected to the contact carrier of the contact pair and at least one with a separate side contact carrier is coupled and that the Drehhe- are rotatably mounted on the support base in such a way that when contacting both the contact carrier of the contact pair and the contact carrier with the side contact to be contacted are moved towards each other.
- An equipped with at least one relay in this training defibrillator results in increased accuracy in the contact, especially for a longer period.
- An advantageous construction consists in that at least one contact carrier is designed as a spring-elastic contact carrier in the pivoting direction.
- the guided contact can also be used with pivotally mounted, rigid contact carriers or a combination of pivotally mounted rigid and resilient contact carriers.
- a further advantageous structure for the construction and the function is that the or the rotary lifting or is rotatably mounted on a respective fixed bearing element is / are mounted on a bearing plate of the support base / are.
- An advantageous embodiment for the production results from the fact that the rotary lifting are produced as a shaped part, in particular punched parts made of flat material.
- FIGS. 3A and 3B are identical to FIGS. 3A and 3B.
- FIG. 1 shows a perspective side view of a relay 1 with a carrying base 50 on which a coil 40 and one of these via an armature 30 and other mechanical see intermediate links in the form of a Drehhebeian Aunt 20 actuated contacting 10 are mounted.
- the coil 40 is held on a bobbin 42 and has a winding 41 which surrounds a core 43 (see Fig. 3A).
- the coil 40 is energized when electrically driven and acts in a conventional manner on the armature 30 which is pivotally mounted at a lower end portion of the bobbin 42 at a pivot point S (s. Fig. 2A) and mitteis electromagnetic force at its trigger lever 301st is tightened, whereby a pointing in Fig. 1 upward control lever is pivoted to the left.
- the control lever 302 advantageously pivots back by means of spring force, ie. H. in Fig. 1 to the right.
- FIGS. 2B and 3B wherein the pivoting of the armature 30 about the pivot point S by a pivot angle a1 with change in the direction R of the pivot position is visible.
- the attracted state of the armature 30 is shown in FIGS. 2B and 3B, so that an angle position a2 of 0 ° results.
- the contacting unit 10 is designed as a changeover contact arrangement with two lateral contact carriers, namely a first contact carrier 12 and a third contact carrier 14, and one of these separate central contact carriers, namely a second contact carrier 13, like FIGS. 1, 2A and 2B demonstrate.
- the contact carriers 12, 13, 14 in the form of contact fingers are mounted with their lower end portion on a base plate 51 of the support base 50 and carry in its upper end region on the sides facing each other contacts 1, 11 ', wherein on the central contact carrier 13 on both sides of contacts 11 'are arranged, which form a contact pair.
- the contact carriers 12, 13, 14 are pivotable, so that their contacts 11, 11 'can be mutually brought by means of the armature 30 in contact (in the sense of an immediate abutment or touching) or (in other control) can be separated from each other to produce or interrupt an electrically conductive connection.
- a distance D is then created between the contacts which are in each case open.
- the armature 30 is in this case from the unadjusted pivot position under the pivot angle a1, in which it is brought by spring force of at least one of the resilient contact carrier 12, 13, 14, wherein the two right contacts 11, 11 'are contacted (Fig.
- the armature 30 acts via the rotary lever assembly 20 on the contact carrier 12, 13, 14.
- the rotary lever assembly 20 has three rotary levers, namely a first rotary lever 21 which is coupled to the first contact carrier 12 via a rotary lever support member 211, a second rotary lever 22, which is coupled to the second contact carrier 13 via first and second rotary lift support members 221, 222, and a third rotary lever 23 coupled to the third contact carrier via a rotary lift support member 231, as more clearly shown in Figs. 3A and 3B.
- the rotary levers are mounted rotatably on bearing elements 53 on a bearing plate 53 mounted on the base plate 51 parallel to the pivoting plane, namely the first rotary lever 21 on a first pivot bearing 531, the second pivot lever 22 on a second pivot bearing 532 and the third pivot lever 23 on a third pivot Pivot bearing 533, as Figs. 2A and 2B and 3A and 3B also show.
- the third rotary lever 23 closest to the spool 40 is in this case connected with its lower pivoting section to the control lift!
- the rotary lever support members are disposed on a respective upper lever arm of the rotary levers 21, 22, 23 so as to engage the associated contact carriers
- both the contacts which are to be contacted are formed by the rotary levers 21, 22, 23, which are rotatably mounted in the rotary bearings 531, 532, 533 and coupled to the contact carriers 12, 13, 14 11, 11 'guided towards each other, wherein the distance traveled by the mutual contacts 11, 11' paths and thus the movement time are shortened accordingly.
- the selected leverage ratios of the rotary levers 21, 22, 23 can be chosen such that the two contacts 11, 11 'to be contacted lie in each case halfway between the contacts for contact via the path of movement, whereby the time to contact with respect to the Movement of only one contact carrier is significantly shortened (eg in the order of 5 ms). Also results in an improvement of the contact by shortening the bounce between the contacts, including the coupling of the rotary lever 21, 22, 23 with the contact carriers 12,
- the rotary levers 21, 22, 23 are for example punched out of flat material, wherein they are provided with round openings on the pivot bearings 531 designed as projections, 532, 533 are stored.
- the rounded cutouts advantageously overlap the adapted rounded coupling counter sections 232, 224 by more than 180 °, whereby a simple engagement in the direction perpendicular to the bearing plate 52 is made possible.
- the rotary lever support members 211, 221, 222, 231, which project at right angles on the flat rotary levers 21, 22, 23, z. B. be made by right-angled folds of the rotary lever itself or by attached bearing pieces optionally with attached rotary sleeves or good sliding surfaces.
- the armature 30 engages with a likewise rounded end portion at the free end of the control lever 302 in an adapted rounded recess on the lower lever portion of the third rotary lever 23, so that thereby also a substantially friction-free sliding bearing similar as between the Koppeiabroughen 212, 232 and the coupling counterpart sections 232, 224.
