Definitions
- the present invention relates to a temperature dependent Switch with a temperature-dependent switching mechanism, the one Rear derailleur-receiving, closed housing, which is a lower part and has an upper part made of insulating material, two on the Upper part on the inside of the stationary contacts provided, each with an external connection assigned to it is electrically connected, and one moved by the switching mechanism Current transmission element, the two depending on the temperature electrically connects stationary contacts.
- 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 on this is held.
- the lower part can be made of metal or insulating material be made, while the upper part in any case made of insulating material is made.
- the rear derailleur carries a current transmission element in the form of a contact bridge, depending on the temperature with the two stationary contacts is brought into contact with each other and then electrically connects.
- 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 guided circumferentially in the housing, while the bimetallic disc is depending on the temperature at the bottom the lower part or on the edge of the spring washer and either the contact bridge on the two allows stationary contacts or the contact bridge stands out from the stationary contacts, so that the electrical Connection between the external connections is interrupted.
- This temperature-dependent switch is made in a known manner used to prevent electrical devices from overheating pour.
- the switch is electrically connected to the one to be protected Device connected in series and mechanically on the device arranged that it is in thermal connection with this.
- The is below the response temperature of the bimetallic disc Cortact bridge on the two stationary contacts so that the circuit is closed and the device to be protected is supplied.
- the temperature rises above an allowable Value, the bimetallic disc lifts the contact bridge from the stationary contacts, whereby the switch opens and the supply of the device to be protected is interrupted, so that it can cool down again.
- a disadvantage is the complex manufacture of the known Switch, after making the cover namely the rivets are subsequently attached to this.
- a 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 Manufacture of a ready-to-connect cable 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 molded with two connecting tongues, of which the first with a stationary contact in the middle connected is.
- the second connecting tongue is provided with tabs, the electrically with the lower part when the upper part is installed are connected.
- 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.
- connection electrodes in the top can be poured into the the stationary Contacts on the inside of the upper part with external connections connect outside the top.
- connection electrodes can in a first step with stationary Contacts as well as the external connections, whereupon then the connecting electrodes when spraying the upper part be poured in or overmolded, so to speak.
- the new switch as well So the new method of making it is that it's easy to make.
- connection electrodes now the external connections geometrically can be placed anywhere with the stationary contacts, the external connections themselves now as solder, 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, with further preferably the connection electrodes in parallel next to each other 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, this results in also better heat absorption and heat supply inside of the new switch towards the temperature-dependent switching mechanism.
- connection electrodes on a band next to each other are punched out in one piece with the respective external connection, preferably the outer sockets via associated retaining webs be held on the tape.
- connection electrodes This measure is advantageous in terms of production technology, because the geometric assignment of the connection electrodes to each other predetermined by punching out and during overmolding with the upper part retained by the holding bars.
- sockets also after Extrusion protrude from the top anyway, so that them at the same time for attaching the connection electrodes to the Band can serve. After pouring the connection electrodes these are from the tape and thus from each other Cut.
- connection electrode with associated External connection only has to be done in a next step stationary contact are welded on before then the upper part is encapsulated.
- Another advantage is that not part of the connection electrode as a stationary contact is bent downwards, but that the connection electrode itself, so to speak, is preserved as a flat part on which the stationary contact is welded on. This results in but clear geometric conditions, errors when punching out or bending the connection electrode cannot lead to that the position of the stationary contacts changes. For the sake of completeness, it should be mentioned that the two stationary contacts must be at approximately the same level, thus the contact bridge securely on both stationary contacts is present.
- the advantage here is that it is made of metal A good thermal connection of the new switch to the device to be protected, but still a good one sufficient lateral electrical insulation through the cup-like Upper part made of insulating material is reached. Furthermore results Get a good seal on the outside of the housing because of the the lower part ring-shaped overlapping edge of the upper part can be hot stamped or welded.
- 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 the upper and lower part, which results in a Kind of labyrinth seal representing the inside of the case is protected from dirt, etc.
- This measure ensures not only for a very dust-tight seal of the housing, it also enables easy manufacturing, since after inserting the rear derailleur upper and lower part only need to be locked together to all Connect parts of the switch captively to one another. After that the switch can then be arbitrarily connected to a welding or stamping station transported where the protruding edge is welded or is stamped.
- 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, on the latter raised edge 15 an outer circumferential groove 16 is provided. On the raised edge 15 is supported cup-like upper part 17 with an inner shoulder 18. A shoulder 19 protrudes over the shoulder 18, one inside circumferential bead 21 is provided which engages with the Is groove 16, whereby the lower part 14 with the upper part 17th is locked.
- the edge 19 merges into an annular overlap 22 which the lower part 14 is held on the upper part 17.
- This overlap 22 can by stamping or welding a protruding area of the edge 19 are generated.
- the lower part 14 While the upper part 17 is made of insulating material, the lower part 14 also made of insulating material or metal be made, with a lower part made of metal better thermal connection of the switch 10 to a to be protected Device results.
- the two stationary Contacts 26, 27 are on an inner side 28 of the upper part 17 arranged.
- the two stationary contacts 26, 27 is a current transmission element in the form of a movable contact bridge 29 assigned to the temperature-dependent via a rivet 30 Switch 12 is connected.
- 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. 2 is to recognize that the two connection electrodes 24, 25 in one piece are connected to external connections 38, 39 which are shown in FIG Case are provided as crimp connections. If the contact bridge 29 is in contact with the two stationary contacts 24, 25, consequently, the two external connections 38, 39 are electrical Conductively connected to one another, the switch 10 is therefore closed.
- annular space 41 is provided for receiving the switching mechanism 12, wherein on Bottom of the annular space 41, which corresponds to the inside 28, two Receiving spaces 42 and 43 for the stationary contacts 27 and 26 are provided.
- 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 45, 46 are provided, via the on the one hand a thermal coupling of the switch 10 to device to be protected, 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 by test pins to contact from outside to ensure the function of the switch 10 to test.
- connection electrode 24 25 two holes 47 are provided through which Web 48 of the upper part 17, which when spraying the Top 17 arise and for an immovable fit Provide connection electrodes 24, 25 in the upper part 17.
- connection electrodes 24, 25 for the manufacture of an upper part 17 are delivered.
- the Connection electrodes 24, 25 and 24 ', 25' are in pairs assigned and each have a blade-like head 51, which is integral with the respective via a tapered web 52
- External connection 38 and 39 is connected.
- the external connection 38 or 39 is again in each case via a thin holding web 54 connected with a band 55, provided on the transport holes 56 are to advance the tape 55.
- Fig. 3a The entire arrangement shown in Fig. 3a can e.g. from a Sheet metal are punched out, followed by the stationary ones Contacts 26, 27 are welded, as shown in Fig. 3b is. Then there is a pair of connection electrodes 24, 25 or 24 ', 25' a cup-like upper part 17 is injected. After the spray compound has hardened, the retaining webs are then 54 severed, the upper part 17 being separated from the band 55 and simultaneously the two electrodes 24, 25 be separated from each other. During the further production then the switching mechanism 12 in the upper part 17 or the lower part 14 inserted, the housing 11 by latching between the upper part 17 and lower part 14 closed and finally through Stamping or welding the annular overlap 22 produced. The openings 45, 46 serve for pressing down of the upper part 17 on the lower part 14. Die by the manufacturing pressure achieved via the electrodes is better than when directly on plastic areas of the upper part 17 would be pressed, since the dimensional accuracy here is worse.
