Definitions
- the present invention relates to a temperature dependent Switch with a temperature-dependent switching mechanism, the one Rear derailleur housing, which is a lower part as well as a Has upper part, two on the upper part on the inside provided stationary contacts, each with a it is connected to an external connection assigned to it and one the switching mechanism arranged and moved by this switching element, depending on the temperature with the two stationary Contacts in attachment.
- the known switch has a housing with a cup-like Lower part in which a temperature-dependent switchgear is inserted is.
- the lower part is closed by an upper part, which is held on by the raised edge of the lower part becomes.
- the lower part can be made of metal or insulating material be made, while the top here in any case Insulating material exists.
- the rear derailleur carries a current transmission element in the form of a contact plate, which depending on the temperature with the two stationary contacts in System is brought and then electrically connected.
- the outer heads of the two rivets serve as solder connections for strands.
- the temperature-dependent rear derailleur has a bimetallic snap disc as well as a spring washer that is centered on are penetrated a pin that carries the contact plate.
- the Spring washer is guided circumferentially in the housing the bimetallic snap disc depending on the temperature on the floor of the lower part or on the edge of the spring washer and either the contact plate on the two allows stationary contacts or the contact plate stands out from the stationary contacts, so that the electrical Connection between the external connections is interrupted.
- This temperature-dependent switch is used in a known manner used to protect electrical devices from overheating.
- the switch is electrically connected to the one to be protected Device connected in series and mechanically arranged on the device that it is in thermal connection with it.
- Below the response temperature of the bimetallic snap disc the contact plate is in contact with the two stationary contacts, so that the circuit is closed and the device to be protected is supplied.
- the temperature rises above an allowable The bimetallic snap disc lifts the contact plate from the stationary contacts, causing the switch opened and the supply of the device to be protected is interrupted so that it can cool down again, whereupon the switch closes automatically.
- the dimensioning of the contact plate is the known one Switch able compared to other temperature dependent Switches where the operating current of the to be protected Device directly via the bimetallic snap disc or a their associated spring washer flows, much higher operating currents to guide so that it can protect larger electrical Devices with high power consumption can be used.
- the known switch technically fulfills many requirements, he still has disadvantages in certain applications on.
- the known switch can also have a current-dependent Switching function, which is another resistor is provided, which is permanently in series with the external connections is switched.
- the operating current of the to be protected The device therefore flows continuously through this heating resistor can be dimensioned so that when a certain operating current ensures that the bimetallic snap disc heated to above their response temperature is, so that the switch already at an increased operating current opens before the device to be protected heats up excessively Has.
- This function is also in the known switch but not reliably implemented because the heating resistor is geometrical further away from the bimetallic snap disc is arranged as the resistor for the self-holding function.
- the known switch does not show how manufacturing tolerances can be balanced, including the assembly seems extremely complex and probably only by hand is to be carried out.
- this object is achieved in the aforementioned Switch solved in that geometrically in the area of the current transmission element and upper part arranged at least one resistor is that at least then electrically between the stationary Contacts is switched when the current transfer element with these in annex.
- the object on which the invention is based is achieved in this way completely solved.
- the inventor of the present application has namely recognized that it is also in the generic switch is possible a resistor in the immediate vicinity of the rear derailleur to arrange, so as the thermal coupling of the bimetallic snap disc to the one developed by this resistance To improve heat so that a reproducible and Fast response behavior with current-dependent switching or a reliable keeping open with the self-holding function is achieved.
- This can affect the self-holding function done that the resistance is provided on the upper part or that Upper part itself is designed as a resistor, as it is e.g. at a PTC cover is the case.
- the resistance can be provided on the current transmission element, so that it is only then connected in series between the fixed contacts is when the switch is closed Operating current of the device to be protected.
- the one on the Current transmission element which can be a contact plate, provided Resistance is in the immediate vicinity of the bimetallic snap disk, so that there is an exact response time can be realized because of the good thermal coupling.
- the resistance value determine reproducibly at what amperage and after the length of time the new switch opens reliably. Is additional the resistance is still provided on the upper part, so it remains the new switch also opened reliably, though here because the very good thermal coupling, even low residual operating currents sufficient to develop the necessary warmth.
- Another advantage of the new switch is that it is small constructive effort to see with one or both of the safety functions that can now be achieved can.
- Even the generic switch was simple to be automated, now only in the manufacturing process a current transmission element modified according to the invention and / or one in accordance with the invention an upper part with a resistance must be used, while all other parts of the new switch to those of the generic Switch.
- the generic Switch only two other components are available, so that you can choose between four different modules Switches can be implemented, namely the generic Switch, a switch with a self-holding function or current-dependent switching or even both safety functions.
- the rear derailleur comprises a bimetallic snap disk that is mechanical is connected to the current transmission element and this below their switching temperature against the stationary contacts presses and stands out above their switching temperature, further preferably the rear derailleur against a bimetallic snap disk working spring washer that the Current transmission element in the sense of a system to the stationary Prestressed contacts, and the bimetallic snap disk the current transmission element above their switching temperature from the stationary Contacts, preferably also the spring washer between the current transmission element and the bimetallic snap disk is arranged.
- the current transmission element is on is approximately round contact plate, which by a pin-like Rivet is centrally connected to the bimetallic snap disc.
- each one End with the resistance and end with one of the two stationary contacts is connected, further preferably the upper part is interspersed with two rivets, the inner one Heads as stationary contacts and their external heads serve as external connections, further preferably the resistance is selected from the group heating wire, heating foil, Sheet resistance or PTC resistance.
- both the power transmission link and the top can with their connection options for different resistors and resistance values as mass parts kept in stock be, depending on the requirements of the respective area of application with different types of resistance and / or Resistance values and loaded into the production line be so that the most varied in an extremely simple manner Switches can be produced.
- the upper part itself is made of PTC material.
- Fig. 1 10 denotes a temperature-dependent switch, which comprises a temperature-dependent switching mechanism 11, which in a housing 12 is housed.
- the housing 12 comprises a lower part 14 and a closing part Upper part 15, which by a flanged edge 16th of the lower part 14 is held on this. Between the lower part 14 and the upper part 15, a ring 17 is arranged, the is supported on a shoulder 18 of the lower part 14 and there a spring washer 21 of the switching mechanism 11 leads at its edge.
- the temperature of the bimetallic snap disk 22 increases their response temperature, so it snaps from the one shown convex into a concave shape and supports itself their edge in the area of the ring 17 and pulls the contact plate 24 against the force of the spring washer 21 from the stationary Contacts 31, 32 away; switch 10 is now open.
- Fig. 2 is a top view of the inside 37 of the top 15, with the stationary contacts 31, 32 shown and the rivets 33, 34 are indicated.
- Arc-shaped extend between the stationary contacts 31, 32 Resistance tracks 41, 42, which at their ends with Pads 43 and 44 are connected, which under the guide the inner heads of the rivets 33, 34 and with them accordingly are electrically connected.
- Part 15 is made entirely or partially from PTC material.
- the switch 10 with a current-dependent opening function be provided for what between the contact surfaces 27, 28 heating resistors 45, 46 are switched as this the top view of the contact plate 24 in Fig. 3 can be seen is.
- the contact surfaces 27, 28 arrive with dashed lines in FIG. 3 indicated stationary contacts 31, 32 in the system, the operating current from the stationary contacts 31, 32 via the contact surfaces 27, 28 and the resistors 45, 46 flows, which thus heat up due to this current flow.
- the current intensity takes a predetermined time over a predetermined time Value, the heating resistors 45, 46 develop one sufficient heat to the bimetallic snap disk 22 over its Heating the response temperature. Because the heating resistors 45, 46 are arranged directly on the contact plate 24 results a particularly good thermal coupling between the Heating resistors 45, 46 and the bimetallic snap disk 22, see above that a very precise switching function can be set.
- the heating resistors 45, 46 can also on the bimetallic snap disk 22 facing side of the contact plate 24 is arranged be.
