Definitions
- the invention relates to a temperature sensor with the features of the preamble of claim 1.
- Thermally sensitive devices are known from the prior art which have a housing made of insulating material, to which a heat-conducting element in the form of a heat transfer plate or the like is attached, which is arranged on a wall of the housing or forms it. Furthermore, a sensor element is provided in the interior of the housing in the area of the heat-conducting element, which registers the temperature at the heat-conducting element or the ambient temperature and, depending on this, emits a signal or initiates a switching operation. Furthermore, two connecting elements are provided on the housing, which protrude from the housing.
- the invention is based on the object of designing a temperature sensor with the features of the preamble of claim 1 in such a way that the contacting of the components arranged in / on the housing with one another is simplified. In particular, a fully automatic assembly of the sensor should also be possible.
- At least one electrically conductive pin should now be provided in the housing, with one end of the thermally sensitive element (sensor element) acted upon with pressure directed against the heat-conducting element and with its other end is supported on one end of one of the two connection elements inside the housing.
- the essence of the invention is to provide, instead of providing wiring in the interior of the housing, at least one pin which is quasi clamped between the connector element assigned to it and the electrical contact surface of the sensor and also due to the bias of the elements acting on it, in particular the connector element for one provides sufficient contact pressure under different thermal conditions. Soldering or welding processes to bring about the contacting of the connection elements with sensor parts can thus be completely dispensed with, after only mechanical components have to be joined together.
- both connection elements can be connected to their associated electrical components in the manner according to the invention. It is possible that, for example, one pin directly contacts a surface of a temperature sensor element and the other pin a contact surface of a substrate or carrier on which the sensor is attached. It is also conceivable that both conductive contact pins which preferably consist of a metal with poor thermal conductivity, e.g. B. made of V2A steel, act exclusively on the contact surfaces of the sensor carrier and the sensor is separately contacted and attached to its carrier.
- a metal with poor thermal conductivity e.g. B. made of V2A steel
- both pins run parallel within the housing, particularly simple conditions result for the production, since then only a uniaxial production pressure has to be exerted on the components involved, by both Simultaneously clamp contacts in their neighboring components.
- connection elements inside the housing are bent in a Z-shape and act on the ends of the pins assigned to them with the Z-shaped ends, particularly advantageous spring properties result in the area of the ends of the connection elements.
- separate contact spring parts can also be provided.
- the heat-conducting element can be a baffle plate that covers a housing recess in which the thermally sensitive element or the carrier assigned to it is arranged, wherein the carrier can be a ceramic carrier.
- the pin or pins are guided axially displaceably in their central region, the pins being guided through bores which penetrate a central wall of the insulating material housing.
- pins of different lengths can be provided, for example if one pin acts on a substrate and the other pin acts on a higher surface of an NTC or PTC pill.
- method claim 29 teaches a particularly simple and cost-saving method of how the components already outlined in the device claims can be joined together and connected to form a temperature sensor.
- FIG. 3 shows a detailed top view of a sensor carrier on which a sensor element in SMD construction is fastened
- FIG. 5 shows a central longitudinal section through an embodiment of the temperature sensor corresponding to FIG. 2 with a dome-shaped moisture protection covering
- Fig. 6 is a plan view of a device combination consisting of a temperature sensor and a temperature fuse.
- the temperature sensor designated overall by 1, has a housing 2 made of insulating material, on the underside 3 of which a heat-conducting element 4 with a fastening bolt 5 is arranged. Furthermore, a thermally sensitive sensor element 6 is provided, which is arranged in the region of the heat-conducting element 4 and is in thermal contact with the latter.
- two connecting elements 8, 9 protrude laterally from the housing 2.
- two electrically conductive pins 10, 11 are provided, which have one ends 12, 13 against the heat-conducting element 4 and act on the sensor element 6 or an associated contact 18 and with their other ends 14, 15 on the interior of the housing Support ends 16, 17 of connection elements 8, 9.
- the pin 10 acts with its lower end 12 on a contact surface 19 of the sensor element designed as an NTC or PTC pill, which is connected with its other contact surface to the connection contact 18, which extends from the lower end 13 of the pin 11 is pressurized.
- Both pins 10, 11 run parallel within the housing 2 and are arranged equidistant from the center 20 of the housing 2.
- connection elements 8, 9 are bent in a z-shape toward the upper side 7 of the housing.
- the connection elements 8, 9 are held in place in the housing 2 by rivet connections in a manner known per se.
- the two pins act on a ceramic carrier 25 on which the sensor element 6 'is arranged, which is located centrally between the two lower pin ends 12, 13.
- the lower pin ends can be sharpened to ensure a higher effective contact pressure.
- the carrier 25 and / or the thermally sensitive element 6, 6 ' can be pre-fixed on the inside of the heat-conducting element 4 in order to facilitate the assembly process.
- the heat-conducting element 4 is a baffle plate covering a housing recess 26.
- the housing recess 26 receives the sensor element 6, 6 'and / or the ceramic carrier 25, so that good heat transfer from the fastening bolt 5 via the heat-conducting element 4 to the sensor element 6, 6' is ensured.
- the two pins 10, 11 are axially displaceable in their central region in bores 30 which penetrate a central wall 31 of the housing 2.
- the middle wall 31 separates the first housing recess 26 receiving the thermally sensitive element 6, 6 'from a second housing recess 35, in which the ends 16, 17 of the connection elements 8, 9 inside the housing are arranged.
- a moisture protection covering 50 emerges from the drawing figures, which completely covers both the ceramic carrier 25, 25 'and the sensor element 6, 6' and the associated contact surfaces 18 mounted thereon as a silicone coating.
- the tips 12 and 13 of the pins 10, 11 act upon Assembly process, the surface of the moisture protection sheath 50 is so strong that, similarly to the contacting of a flat cable, the insulation layer is perforated, as a result of which punched recesses are formed which permit clean electrical contacting.
- the pins 10, 11 can have different lengths, in the drawing. 2 an embodiment is chosen in which the pins are of equal length.
- the thermally sensitive element is a relatively thick NTC or PTC pill which is acted upon directly by the pin 10 in order to be able to use the same pins, in the embodiment shown in FIG. 4 the carrier 25 "also bent in a Z-shape to compensate for the thickness of the NTC or PCT element.
- a thermally sensitive element 6 ' which can be an SMD component, can be arranged on the carrier 25 between two connection contacts.
- the temperature sensor 1 is combined on a common mounting bracket 70 with a further thermally sensitive device or switching device 71, which in particular has the advantage that exactly the same temperature is detected by the two mounting bracket 70 by both devices.
- the temperature sensor 1 utilizes the information obtained via an electronic measuring or switching device, whereas in the further switching device 71 a switching process such as the interruption of a current path or the switching on of signal elements takes place immediately when a limit temperature is exceeded or reached.
- a switching process such as the interruption of a current path or the switching on of signal elements takes place immediately when a limit temperature is exceeded or reached.
