Definitions
- the current application is directed to a measurement setup for measuring a temperature and a holder.
- Temperature detection or temperature measurement is relevant in various technical systems. This also applies in particular to electric motors, for example for electromobility applications.
- An object of the present invention is to provide a method for measuring temperature that improves on the concepts presented above. Further objects are solved by advantageous embodiments of the invention.
- a measurement setup for measuring a temperature of a test body with at least two separate lines suitable for heat conduction being led away from a test body and combined into a line bundle at a distance from the test body.
- a temperature sensor is fastened to the line bundle by means of a holder by means of a clamping effect.
- lines suitable for heat conduction are preferred, ie those with good heat conduction.
- the heat conduction of metals can be considered.
- the lines therefore preferably have metallic components or consist of metals.
- the leads may have a core that includes metallic components and is encased in insulation.
- the jacket can be thermal or electrical insulation. Copper, silver, aluminum or gold are preferred as metallic components.
- alloys with a high proportion of these metals are preferred, with a high proportion corresponding to a proportion of these metals of at least 50%.
- a core or the entire line consists of one of the metals mentioned above. It can be copper lines, for example.
- the lines are routed away from the test body and are combined in a line bundle at a distance from the test body. This means that the temperature is measured on the cable bundle and not directly on the test object. This can enable a temperature measurement of locations on the test body which are inaccessible for the direct attachment of a sensor. It is sufficient if lines can be attached to the test specimen.
- the distance from the test body can be understood to mean that at least one of the lines is not directly combined with another line or multiple lines in the line bundle at its starting point on the test body. It does not matter whether the lines are already bundled directly on the test object or not.
- the bundle of lines can preferably be interpreted in such a way that it is a bundled area of the lines on which the temperature measurement is also carried out is, i.e. on which the bracket and the temperature sensor rest.
- the distance between the origin of the lines and the bundle of lines is preferably 1 to 100 cm, measured along the course of the lines.
- the line bundle can be referred to as a measuring body on which the actual temperature measurement is carried out, ie on which the temperature sensor is in contact.
- the test specimen is the body whose temperature is to be recorded with the measurement setup.
- the at least two lines are bundled into a line bundle.
- the lines in the area of the line bundle are preferably routed largely parallel and in direct contact with one another. Outside of the line bundle, the lines can be unbundled.
- the lines are preferably at least partially stripped of insulation if they otherwise have insulation. This has the advantage that the temperature can be measured directly on the heat-conducting metallic components.
- the temperature sensor used here is basically any temperature sensor. In particular, it is preferably suitable for precisely detecting the temperature in a temperature range between ⁇ 55° C. and 300° C., or even more preferably in a temperature range between ⁇ 40° C. and 200° C. In particular, an NTC sensor is preferred as the temperature sensor.
- the temperature sensor is attached to the wire bundle by means of a clamping effect.
- the temperature sensor is preferably clamped to the line bundle.
- the holder is preferably clamped around the bundle. Accordingly, the temperature sensor is not inserted between the at least two separate lines. Any suitable holding device can serve as the holders.
- a clamping mount or clamp is preferred. More preferably, the bracket or clamp described below is employed.
- the holder or clamp can also be suitable for holding the cables together as a bundle of lines. However, this is not necessary and can be achieved by other measures.
- the measurement setup is designed in such a way that all lines are attached to different points of the test body.
- all lines can originate from different points of the test body.
- the temperature sensor can measure an average temperature of the at least two different points.
- an even better inventive advantage can be achieved because such an average temperature many measuring points of the test body can be recorded without having to attach several temperature sensors, which are bulky compared to cables, directly to the test body.
- the lines in the area of the line bundle are combined by a bundling means.
- the temperature sensor is clamped or pressed onto the bundling means by the holder.
- the bundling means is a part that is separate from the holder.
- the temperature is preferably measured at the bundling means.
- the bundling means can thus be referred to here as a measuring body according to the definition given above.
- the bundling means preferably has a surface against which the temperature sensor with the holder can be pressed.
- the bundling agent preferably has good thermal conductivity. Furthermore, the bundling means is preferably mechanically stable.
- the bundling means is preferably a metallic bundling means. Many metals have both high thermal conductivity and sufficient mechanical stability.
- the bundling agent includes iron, steel, stainless steel, copper, aluminum, or alloys containing these materials. It can be made of these materials. Of these materials, steel or stainless steel is particularly preferred, since it is particularly mechanically stable in comparison and has sufficiently good thermal conductivity.
- bundling means can also be coated
- the lines can be at least partially stripped of insulation in the area of the bundling means if they otherwise have insulation in addition to the thermally conductive material.
- the bundling means can be a crimp.
- the bundling means is more preferably a hot impact.
- a hot impact has the advantage that possible insulation can be stripped automatically by the temperature during the process of attaching the crimp, i.e. during crimping.
- the hot impingement can preferably have an oval shape with a smooth surface.
- the smooth surface is particularly well suited for the temperature sensor to be clamped to it.
- a suitable holder for example as described below, can be attached particularly efficiently to an oval shape.
- the lines can be electrical lines. They can preferably be electrical power supply lines to the test body or serve as such.
- test body can be an electric motor.
- An electric motor is particularly suitable for the above-mentioned measuring method or the measuring setup, since common motors often have many places that are inaccessible for temperature measurement.
- a holder is described.
- the invention is primarily aimed at a holder, but also in connection with a temperature sensor that can be accommodated in this holder and with a measuring body, on which? this can be attached is described.
- the holder is to be considered independently of these other components according to the invention.
- the invention also includes any described arrangement in which the holder is installed together with a measuring body and/or a sensor.
- the invention also includes an ensemble of these components, in which case the components can be present next to one another in an ensemble without being built into one another.
- a mount which has a mount base with an inside and an outside and spring clips connected thereto.
- a depression for receiving a temperature sensor is arranged on the inside of the mounting base.
- two of the spring clamps are arranged opposite to each other with respect to the mounting base. These are capable of generating a clamping force towards the inside of the mounting base.
- the inside is preferably the side which faces a measuring body in a measuring setup or a measuring arrangement.
- the outside is thus preferably the side facing away from this measuring body.
- the indentation is arranged in the holder base on its inside so that a sensor to be inserted into the holder can lie directly on a measuring body lying on the inside, for example a hot impingement, without parts of the holder being arranged between the sensor and the measuring body .
- the temperature sensor preferably comes to rest with a contact surface on the measuring body. The contact surface is particularly suitable for making a thermally conductive contact.
- the contact surface preferably faces away from the inside of the mounting base.
- the two spring clamps which are opposed to each other with respect to the support base, form a pair. Due to their corresponding arrangement, they can encompass a measuring body, for example a hot impingement, from two opposite sides, i.e. mutually. Thus, the force can be symmetrical from both sides. This also allows some of the clamping force to act towards the inside of the mounting base. A temperature sensor to be inserted into the recess can thus be pressed against a measuring body.
- the sensor can be pressed into the depression by means of a clamping force in the direction of the inside of the mounting base, without the need for further mountings, fastenings or clamping of the temperature sensor in the mounting.
- a portion of the clamping force can also act from one of the spring clamps in the direction of the other spring clamps and consequently clamp the measuring body between the two clamps.
- the depression comprises a stop which can prevent a movement of a temperature sensor to be inserted into the depression out of the depression.
- a temperature sensor to be inserted is in contact with the stop.
- the direction from the center of the depression perpendicular to the stop can be referred to as the insertion direction of a temperature sensor to be inserted.
- the temperature sensor to be inserted is consequently preferably inserted in the direction of insertion.
- the stop inhibits a movement of the temperature sensor out of the recess in the direction of insertion. Furthermore, it is preferred that a sensor to be inserted is limited on other sides, for example by the spring clamps or by side walls of the mounting base, from which the spring clamps extend, as explained above.
- the holder comprises a clamping lug which is provided and suitable for fixing a temperature sensor to be inserted in the recess.
- the temperature sensor can be held or fastened in the depression without the holder with the sensor having to be pressed onto a measuring body.
- clamping tab extends from an interior portion of the mounting base.
- the clamping tab extends along one side of the recess.
- the clamping tab extends from an interior portion of the mounting base along a direction defined parallel to the outside-to-inside direction.
- the clamping lug is preferably not arranged on the side on which the stop is arranged. Even more preferably, the clamping lug is arranged parallel to the direction of insertion and the clamping effect of the clamping lug acts perpendicularly to the direction of insertion.
- the clamping lug preferably clamps a sensor to be inserted into the depression against a side wall of the depression lying opposite the clamping lug.
- a portion of the force can also act in the direction of the inside of the sensor base.
- the clamping lug does not extend to the contact surface of the sensor.
- the clamping lug can cover the sensor partially enclose without extending to the contact surface. Consequently, generally speaking, the clamping lug preferably has an at least partially matching shape to the sensor to be inserted into the recess. As a result, they can at least partially enclose it in a form-fitting manner.
- the clamping lug can engage with an engagement area in a suitable recess or indentation in the sensor in order to improve the fixation of the sensor.
- a second clamping lug can also be arranged on the opposite side of the depression to the clamping lug described above.
- This pair of clamping lugs formed in this way can bring about a symmetrical clamping force load on the sensor. In this way, an even more stable fixation can be achieved.
- the holder can preferably be manufactured in one piece. This has the advantage that weak points at connection points of assembled components can be avoided.
- the holder can consist of the same material in all its areas.
- this has the advantage that the holder is formed from the same flexible material, as a result of which the necessary flexibility and clamping force can be provided both for the spring clamps and for the clamping lug or the clamping lugs.
- the holder can be manufactured as a stamped and bent part. This has the advantage that particularly simple manufacture is made possible.
- Such a holder is preferably made of sheet metal.
- the sheet metal can be preferably steel,
- the sheet metal can be coated.
- the holder can consist of plastic or be made of plastic. So the holder can be particularly light. This can help ensure that the routing of the cables in a cable bundle is not affected by the weight of the mount.
- a suitable plastic can be selected from polyamides such as polyamide 66, polypropylene, polyphthalamides, polyphenylene sulfide or polyurethanes. Basically, the applicability depends on
- Plastic brackets depend on application temperatures. The selection of the plastic can also be adapted to the application temperature.
- the depression comprises an opening which allows electrical lines to be routed into the opening.
- These electrical lines are preferably electrical input or output contacts of a temperature sensor to be placed in the depression.
- the opening can preferably be arranged on the side opposite the stop.
- the direction from the opening side to the stop side can preferably correspond to the insertion direction.
- the electrical lines can also run approximately in the direction of insertion.
- the insertion direction and thus the local routing direction of the lines is preferably oriented perpendicularly to lines in the cable bundle. In this way, the sensor cables can be routed away from the cable bundle as efficiently as possible. In this way, a sharp bend in the line to lead it away can be avoided.
- the depression is shaped in such a way that a temperature sensor can be inserted at least partially in a form-fitting manner into the depression.
- At least partially form-fitting can mean that, for example, a side that is not the one that comes into contact with a measuring body fits into the depression in terms of its shape. In this case, the indentation does not have to replicate every shape feature of the temperature sensor or one side of the temperature sensor.
- form-fitting here means that the shape of the temperature sensor is at least as similar to a negative as to a positive, so that wobbling of the temperature sensor in the recess is minimized.
- the holder comprises two further spring clamps which are arranged opposite one another in relation to the holder base and are suitable for generating a clamping force in the direction of the inside of the holder base.
- the bracket includes four spring clips. These four spring clamps each form pairs of two opposing spring clamps, which can each be understood as pairs of spring clamps.
- the second pair of spring clips can have properties similar to the first.
- the four spring clamps are preferably arranged symmetrically with respect to the mounting base. This can enable a stable four-point fixation or four-point clamping of a temperature sensor to a measuring body.
- the spring clamps are suitable for at least partially enclosing an oval-shaped measuring body in order to produce a clamping effect and to effect attachment to the measuring body.
- the spring clamps resting largely positively but undersized on the measuring body.
- Form-fitting means here in particular with regard to the oval shape, that a part of the spring clamps at least partially reproduces the shape.
- the shape is undersized, i.e. it can be reduced in the relaxed state compared to the shape of the measuring body or, for example, imitate the oval shape with an opening angle that is too small or a radius that is too small.
- the undersized shape is spread, which can create a clamping effect as a counterforce to the spreading.
- the material of the spring clamps is selected in such a way that they are spring-elastic under a temperature load of 100°C to 200°C.
- the holder is particularly well suited for use on electric motors in electric vehicles, since they are spring-elastic in the temperature range that prevails there.
- Engine starting conditions i.e. a temperature range of -20 to 50 °C spring-elastic.

- a clamping lug 17 is formed in one of the side walls. This is suitable for fixing a temperature sensor to be inserted in that it is pressed either by a clamping effect against the opposite side wall of the recess 15 or against the inside 12 . Preferably, the temperature sensor is in both these directions against the Depression 15 pressed.
- the clamping lug 17 is preferably worked out of a side wall.
- the x-direction here corresponds to the direction of insertion of a temperature sensor to be inserted into the holder 1, with the stop 16 preventing movement or sliding out of the recess 15 of the holder 1 in the direction of insertion.
- a flat section of the stop 16 is preferably oriented perpendicularly to the direction in which a temperature sensor is inserted (in this case the x-direction).
- a surface normal of a flat section of the stop 16 is oriented counter to the x-direction.
- a total of four spring clamps 14 extend from the mounting base 15, these extending in such a way that webs 19 are attached to the side walls of the depression 15, on which webs the spring clamps 14 are arranged perpendicular to the course of the web.
- the spring clamps 14 lying opposite one another in the x-direction, which are arranged at two ends of a web 19, can be defined as a pair of spring clamps.
- only two spring clamps could be opposite each other in the x-direction, preferably by filling the free space between the spring clamps 14 that are adjacent in the y-direction with a material connecting the spring clamps.
- the clamping action of the spring clamps 14 is preferably oriented perpendicular to the clamping action of the clamping lug 17 .
- the direction of insertion (x-direction) is parallel to the clamping action of the spring clamps 14. This enables a Insertion of a temperature sensor perpendicular to the course of a measuring body.
- the spring clamps 14 each extend from a web 19 and the clamping effect is oriented parallel to the direction of insertion, the tension or force that is generated by the spring clamps or that acts on the spring clamps in a measurement setup cannot be transferred to the mounting base will.
