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 made of insulating material, two on the upper part provided inside of the stationary contacts, from each of which is electrically connected to an external connection assigned to it is connected, and one moved by the switching mechanism Current transmission element, which is temperature-dependent, the two stationary Connects contacts electrically.
- Such a switch is from DE 26 44 411 C2 and EP 0 453 596 A1, according to the preamble claim 1, known.
- the known switch has a housing with a cup-like Lower part in which a temperature-dependent rear derailleur is inserted.
- the lower part is closed by an upper part, by the raised edge of the lower part this is held.
- the lower part can be made of metal or insulating material be made while the top in any case is made of insulating material.
- the rear derailleur carries a current transmission element in the form of a contact bridge, depending on the temperature with the two stationary contacts in System is brought and these then electrically together combines.
- the outer heads of the two rivets serve as solder connections for strands.
- the temperature-dependent switching mechanism is known per se Have a bimetallic washer and a spring washer that are centrally penetrated by a pin that the contact bridge wearing.
- the spring washer is circumferentially in the housing led while the bimetallic disc varies depending on the temperature on the bottom of the lower part or on the edge of the spring washer supports and either the contact bridge allows the two stationary contacts or the contact bridge stands out from the stationary contacts, so that the Electrical connection between the external connections interrupted becomes.
- This temperature-dependent switch is made in a known manner used to prevent electrical devices from overheating protect. To do this, the switch is electrically connected to the protective device connected in series and mechanically on the Device arranged that it is in thermal communication with this stands. Below the response temperature of the bimetal disc the contact bridge is on the two stationary contacts so that the circuit is closed and that too protective device is supplied. The temperature rises the bimetal disc lifts above a permissible value the contact bridge from the stationary contacts, whereby the switch opens and the supply to the device to be protected is interrupted so that it cools down again can, whereupon the switch closes automatically.
- a disadvantage is the complex manufacture of the known Switch, after making the cover namely the rivets are subsequently attached to this.
- On another disadvantage is that to the outside Rivet heads still need to be soldered to what is in the strands Rule cannot be automated. However, this means that the Production of a ready-to-use assembly with strands Switch here is time consuming and therefore costly.
- DE 31 22 899 C2 is a temperature-dependent one Switch with a lower part made of metal and a housing upper part made of insulating material.
- the upper part is cast in two connecting tongues, of which the first connected to a central, stationary contact is.
- the second connecting tongue is provided with tabs, which are electrically connected to the lower part when the upper part is installed are.
- a Bimetal rear derailleur Inside the closed housing thus formed is a Bimetal rear derailleur arranged depending on its Temperature an electrically conductive connection between the stationary contact and the lower housing part and thus between the two connecting tongues.
- This switch also has another disadvantage in it too see that it automatically switches on again after cooling. While such switching behavior for protection of a hair dryer can be quite useful two switches described so far for the protection of devices not suitable, which does not change automatically after cooling should turn on again, as it e.g. for electric motors may be the case.
- the temperature-dependent To provide switches with a so-called self-holding function which is why there is a resistor parallel to the external connections is switched. After opening the rear derailleur flows in low current through this resistor, which is sufficient Heat developed to the rear derailleur Maintain switching temperature so that the switch automatically does not close again. Rather, the supply voltage must be used for this be switched off so that the rear derailleur no longer through the current flowing through the self-holding resistor is kept above the switching temperature.
- the object underlying the invention is based on this Way completely solved.
- the inventor of the present application has recognized that that it is initially also without constructive changes to the known Switch is possible, one preferably to the outside to provide an open pocket into which a resistor is inserted can be that he with his pads in plant with the two contact surfaces. This will Resistor connected in series between the two external connections, with the switchgear closed, i.e. below by its switching temperature, bridged by the switching mechanism becomes. The temperature of the rear derailleur rises above the permissible value, the short circuit is opened, so that now a small current flows through the resistor, which develops sufficient heat to open the rear derailleur to keep.
- the heating resistor is located in the upper part relatively close to the rear derailleur, so that even small Currents are sufficient to develop the required ohmic heat.
- the switch with a self-holding function to provide, so instead of a resistance also a blind plug to be inserted into the bag the contact areas freely accessible in the bag to the outside isolate.
- the new switch shows great advantages when he was both after his manufacture provided with a self-holding function as well as without it Function can be delivered. In a single production run can therefore use two different switch types are manufactured, which is understandably extremely cost effective is.
- the resistance only needs to be in from the outside the bag can be inserted where it then automatically with the Contact areas come into contact.
- the resistance can be of any Be of a type, a PTC resistor being preferred, has the corresponding pads with which it on the contact surfaces.
- the new switch it is therefore preferred if in the Bag a resistor is inserted, with both contact surfaces is connected so that it is in series between the external connections is switched and for a self-holding function provides, it is preferred if the resistance in the Bag is pinched or glued and / or preferably through a shrink tube surrounding the switch is insulated on the outside.
- the resistor only has to be installed in the Pocket can be inserted where it is either mechanical jammed or held by gluing. additionally and / or alternatively the switch can be operated by one Heat shrink tubing surrounded by the resistance after is insulated on the outside, with the heat shrink tubing in addition can also ensure the mechanical hold of the resistor, so that gluing or clamping entirely or partially can be dispensed with.
- connection electrodes are shed, each with one of the stationary Contacts, one of the contact areas and one of the External connections is connected.
- connection electrodes poured into the upper part can be the stationary contacts on the Inside of the upper part with external connections outside the Connect the upper part.
- a particular advantage is included here the manufacture of the new switch, because the connection electrodes can in a first step with stationary contacts as well as the external connections, whereupon then when spraying the upper part, the connection electrodes, so to speak be poured in or overmolded.
- the manufacture of the upper part itself will be the External connections and the stationary contacts attached to this.
- areas of Protruding connection electrodes into the pocket around the contact surfaces provide with which a resistor contacts can be. Can be done in a single manufacturing step So the upper part together with the attachment of the connection electrodes as well as that for fastening and contacting the Resistance provided pocket can be realized.
- Another advantage is that by choosing the Shape of the connection electrodes now the external connections geometrically can be placed anywhere with the stationary contacts with the external connections themselves now as soldering, Crimp or screw connections can be formed.
- each connection electrode is a flat metal part, with which the respective external connection, which preferably from the side protrudes the upper part, is integrally formed, wherein further preferably the connection electrodes in parallel next to each other lie in the top.
- connection electrodes can e.g. strapped or on Tape are fed, while also having good stability cause the upper part, since they are flat metal parts are. Because of this extensive training results in addition, better heat absorption and heat input in the inside of the new switch to the temperature dependent Rear derailleur.
- the advantage here is that automatically release the pocket when spraying the upper part into which e.g. the metal parts on the side protrude so that areas of their surface there as contact surfaces Act.
- connection electrode is also advantageous in terms of production technology, because after punching out the connection electrode with associated External connection must only in a next step stationary contact are welded on before then the upper part is encapsulated.
- Another advantage is that that not part of the connection electrode as a stationary contact is bent downwards, but that the connection electrode itself remains, so to speak, as a flat part that the stationary contact is welded on. With it result but there are clear geometric conditions, errors in Punching or bending the connection electrode cannot do this cause the position of the stationary contacts to each other changes. For the sake of completeness, it should be mentioned that the two stationary contacts at approximately the same level must lie so that the contact bridge is safe on both stationary contacts.
- the lower part on his Edge has an external, circumferential groove with which one Bead is engaged on the inside on the edge of the top is trained.
- the advantage here is that there is a snap connection, so to speak between top and bottom that results simultaneously represents a kind of labyrinth seal over which the inside of the Housing is protected from dirt, etc.
- This measure not only ensures a very dust-tight seal of the housing, it also enables one easy manufacture, because after inserting the rear derailleur Upper part and lower part are only locked together need to get all parts of the switch captive together connect to. Then the switch can be closed as desired a welding or stamping station, where the projecting edge is welded or stamped.
- a production step can be inserted, where either a resistor or a blind plug in the bag is inserted to either hold it down to effect.
- the resistance is either pressed in, pinched or glued in, he additionally or alternatively held and / or insulated by a shrink tube can be.
- Fig. 1 denotes a temperature-dependent switch, which has a housing 11 in which a temperature-dependent Rear derailleur 12 is arranged.
- the housing 11 comprises a plate-like lower part 14 the raised edge 15 an external, circumferential Groove 16 is provided. Based on the raised edge 15 a cup-like upper part 17 with an inner shoulder 18 from. Over the shoulder 18 protrudes an edge 19 on which one inside circumferential bead 21 is provided which engages with the groove 16, whereby the lower part 14 with the upper part 17th is locked.
- the edge 19 merges into an annular overlap 22, through which the lower part 14 is held on the upper part 17 becomes.
- This overlap 22 can by stamping or welding a protruding area of the edge 19 is generated become.
- the lower part 14 While the upper part 17 is made of insulating material, the lower part 14 also made of insulating material or Be made of metal, with a lower part Metal a better thermal connection of the switch 10 results in a device to be protected.
- connection electrodes 24, 25 cast, each welded wear stationary contact 26, 27.
- the two stationary Contacts 26, 27 are on an inner side 28 of the upper part 17 arranged.

- the switching mechanism 12 includes one Spring washer 34, with its edge 35 circumferentially in a circumferential Groove 36 is guided between the shoulder 18th and the edge 15 is formed.
- the switching mechanism 12 now brings the contact bridge 29 in contact with the two stationary contacts 26, 27 or differentiate them from them.
- the exact function of the bimetal rear derailleur is in the aforementioned DE 26 44 411 C2 described so that for more information on this Reference is made.
- the top view of the new switch 10 according to FIG. 3 is to recognize that the two trained like knife blades Connection electrodes 24, 25 in one piece with external connections 38, 39 are connected, in the case shown as crimp connections are provided. If the contact bridge 29 in System with the two stationary contacts 24, 25 is so consequently, the two external connections 38, 39 are electrical Conductively connected to each other, the switch 10 is therefore closed. In Fig. 3 it can also be seen that in the upper part 17 an annular space 41 is provided for receiving the switching mechanism 12 is.
- the stationary contacts 26, 27 are incidentally on the connection electrodes 24, 25 welded or soldered. From the stationary Contacts 26, 27 are remote in the upper part 17 two outward openings 40 are provided, on the one hand a thermal coupling of the switch 10 to a protective device takes place, these openings on the other hand can be provided for test purposes, namely the inside the switch 10 by heating stamp as quickly as possible and / or the two stationary contacts 26, 27 through Contact test pins from outside to ensure the function of the Switch 10 to test.
- the rear derailleur 12 is in the upper part 17th or the lower part 14 inserted, the housing 11 by locking closed between upper part 17 and lower part 14 and finally by stamping or welding the ring-shaped Attack 22 made.
- the openings serve here 40 for pressing the upper part 17 onto the lower part 14. The reached by the pressure exerted on the electrodes Manufacturing accuracy is better than when directly on Plastic areas of the upper part 17 would be pressed here the dimensional accuracy is worse.
- FIG. 1 there is also shown a web 42 which the two electrodes 24, 25 are insulated from one another in the transverse direction. Above the web 42 is an open to the outside Pocket 43 is provided, in which the two electrodes 24, 25th Extend into the side so that they are in contact with contact surfaces 44, Point 45 into pocket 43.
