[0003] Sensor arrays are used to measure the physical properties of objects. Sensor arrays are known to consist of electronic and mechanical components designed to detect a physical property and output a signal indicating that property.

[0004] Sensor arrays typically include several complex components, which can make manufacturing the arrays problematic.

[0005] From the document US 2013 / 0 031 976 A1, for example, a sensor arrangement is known in which, for connection to a sensor assembly, a cable cover is provided with a first and a second end, a cable which extends through an opening in the first end of the cable cover, and a crimp ring which is configured to receive the cable at a position within the cable cover such that the attached crimp ring does not fit through the opening. The second end of the cable cover can be configured to be connected to a housing of an electrical connector. Furthermore, the cable can have wires which can be configured for electrical connection to electrical terminals of the electrical connector.

[0006] US 2019 / 0 376 865 A1 further discloses a pressure sensor comprising a sensor element, an inner frame configured to receive at least a portion of the sensor element, and a housing configured to receive the inner frame therein. The inner frame is made of a metallic material and includes a circuit board assembly that is electrically connected to the sensor element. The housing is made of a resin material.

[0007] The object of the present invention is to provide an improved sensor assembly and an improved method of providing the assembly which overcome this problem.

[0008] This object is achieved by a sensor arrangement according to claim 1 and a method for assembling the sensor arrangement according to claim 10. Preferred embodiments of the invention are subject of the dependent claims.

[0009] According to claim 1, a sensor assembly is provided comprising an electrical connector having an annular seat, a media connector, at least one PCBA having a lower PCBA key slot, a grounding support having at least one grounding support tab inserted into the lower PCBA slot, and at least one capsule, wherein an inner, annular capsule seat abuts the annular seat. According to the invention, the electrical connector comprises a key slot of the electrical connector that receives the grounding support tab. The key slot of the electrical connector may be a recessed portion on an outer periphery of the electrical connector into which the grounding support tab can be inserted.

[0010] The capsule covers the interior of the sensor assembly and simultaneously provides a contact surface for the electrical connector. The annular seat may further provide a stop or abutment for positioning the electrical connector relative to the capsule in an axial direction of the sensor assembly. The annular seat may extend over the entire circumference of the capsule.

[0011] In a preferred embodiment of the invention, the outer side of the capsule consists of a lower uniformly cylindrical part and an upper crimped capsule part and / or the capsule is cold-drawn.

[0012] The cold drawing of the capsule facilitates its production, while its uniformly cylindrical exterior provides a smooth surface for visual identifiers such as labels or engravings.

[0013] In a particularly preferred embodiment of the invention, the upper crimped capsule portion secures the electrical connector to the capsule. The capsule may be crimped in a radially inward direction such that the crimped capsule portion is at least partially inserted into a corresponding groove or recess of the electrical connector.

[0014] In another preferred embodiment of the invention, the PCBA includes an upper PCBA key slot that receives the grounding retaining tab. Therefore, the same grounding retaining tab can be inserted into the key slot of the electrical connector and the upper PCBA key slot.

[0015] In another preferred embodiment of the invention, the grounding bracket comprises at least one grounding bracket connection part that electrically connects the grounding bracket to the PCBA and / or the capsule.

[0016] In another preferred embodiment of the invention, two PCBAs are provided, an upper PCBA and a lower PCBA, which are connected to each other via PCBA connecting pins. The number of connecting pins can be any number of pins.

[0017] In another preferred embodiment of the invention, the sensor arrangement is a pressure, load, and / or temperature sensor arrangement. One or more sensor elements can be used. The sensor elements can be of the same or different types.

[0018] In another preferred embodiment of the invention, the PCBA and the grounding support are provided entirely within the capsule relative to a radial direction of the capsule.

[0019] In another preferred embodiment of the invention, the grounding bracket provides an electrical connection between the PCBA, the enclosure, and the media connector to shield the PCBA from EMC / EMI noise. The electrical connection between these components means that they are all electrically connected to each other to provide a shield against EMC / EMI noise that might otherwise penetrate the PCBA.

[0020] The invention also relates to a method for assembling the sensor arrangement, the method comprising the steps: Connecting the grounding bracket to the media connector; Connecting the capsule to the media connector; Inserting the PCBA into the capsule; and at least partially inserting the electrical connector into the capsule.

[0021] The process steps can be carried out in the specified order or in any logically possible order.

[0022] Further details and advantages of the invention are described with reference to the embodiments shown in the figures. In the figures: Fig. 1: a perspective view of the sensor arrangement; Fig. 2: another perspective view of the sensor arrangement; Fig. 3: a sectional view of the sensor arrangement; Fig. 4: another sectional view of the sensor arrangement; Fig. 5: a view of the interior of the sensor assembly; Fig. 6: another view of the interior of the sensor assembly; Fig. 7: an exploded view of the interior of the sensor assembly; Fig. 8: another exploded view of the interior of the sensor assembly; Fig. 9: a partially transparent view of the interior of the sensor assembly; Fig. 10: perspective views of the electrical connector; Fig. 11: a perspective view of the electrical connector; Fig. 12: an exploded view of part of the sensor arrangement; Fig. 13: a detailed view of the interior of the sensor assembly; and Fig. 14: a detailed view of the capsule.

[0023] Fig. Figure 1 shows a perspective view of one embodiment of the sensor assembly 1. The sensor assembly 1 includes an electrical connector 2, which may be provided at an upper axial end portion of the assembly 1. The electrical connector 2 may be provided adjacent to and / or above a capsule 3 containing various components of the assembly 1. The capsule 3 shields the components contained therein and may be made of steel.

[0024] On the opposite side of the capsule 3, a hexagon 4 may be provided for rotating the assembly 1 with a suitable wrench. The assembly 1 may include a threaded portion 6 at a lower axial end portion opposite the connecting piece 2. A media connector 5 consists of the threaded portion 6 and the hexagon 4 and can form a seal against media leakage with or without a flat gasket.

[0025] The axial direction of the assembly 1 may correspond to the axial direction of its threaded portion 6. The radial and circumferential directions may also be defined with respect to the substantially cylindrical threaded portion 6.

[0026] Fig. 2 shows a further perspective view of the sensor arrangement 1. In addition to the Fig. 1, a protective part 7 is located at the bottom of the assembly 1. The protective part 7 can be arranged concentrically to the threaded part 6. The protective part 7 can be a fluid passage and / or can extend into the interior of the sensor assembly 1, so that the physical properties of an object can be sensed by the sensor element 15 within the sensor assembly 1, such as in Fig. 5. The sensor element 15 may comprise a pressure sensor, a temperature sensor, and / or a load sensor.

[0027] Fig. 3 shows a sectional view of a portion of the sensor assembly 1. The lower portion of the electrical connector 2 is shown partially inserted into the capsule 3. The electrical connector 2 includes connector pins 8 on its side opposite the capsule 3. An O-ring 9 may be provided between an outer periphery of the electrical connector 2 and a radially inner side of the capsule 3. The capsule 3 may be crimped into an annular groove or ledge of the electrical connector 2 such that a crimped capsule portion 10 fixes the capsule 3 to the electrical connector 2. The crimped capsule portion 10 secures the electrical connector 2 to the capsule 3 and permanently locks it in position.

[0028] A media connector 5 may be provided near the lower end of the sensor assembly 1. At the upper part of the media connector 5, a grounding ring or grounding bracket 17 may be provided around the outer periphery of the media connector 5 and / or within the capsule 3. The grounding bracket 17 may provide contact, preferably electrical contact, between the media connector 5 and other components of the sensor assembly 1. The grounding bracket 17 may combine several different features, such as conducting electrical signals from the capsule 3 to the PCBAs 13, 14, EMC / EMI shielding of the components of the sensor assembly 1, thereby providing mechanical stability for the assembly and / or providing environmental protection.

[0029] Fig. 4 shows a further sectional view of the sensor assembly 1. The electrical connector 2 comprises an annular seat 12 near its lowermost part, which is fully inserted into the capsule 3. The annular seat 12 protrudes in a radially outward direction from the electrical connector 2. The annular seat 12 abuts an inner annular capsule seat 11. The annular inner capsule seat 11 protrudes in a radially inward direction from the capsule 3. The annular inner capsule seat 11 can be a rim on the inside of the capsule 3 and acts as a stop.

[0030] Two PCBAs 13, 14, an upper PCBA 13 and a lower PCBA 14, may be provided in the capsule 3. The upper PCBA 13 may be provided at least partially within the electrical connector 2. The lower PCBA 14 may be provided below the upper PCBA 13 and / or may contact the grounding bracket 17. The lower PCBA 14 may be fixed in an axial direction by the grounding bracket 17 and the electrical connector 2. The lower PCBA 14 may be in direct contact with the grounding bracket 17 and the electrical connector 2.

[0031] In the embodiment of Fig. 4, the PCBAs 13, 14 and the grounding bracket 17 can be provided entirely within the capsule 3. The PCBAs 13, 14 and the grounding bracket 17 can be provided radially within the capsule 3. Additionally or alternatively, the capsule 3 can extend further in the axial direction than the assembled PCBAs 13, 14 and the grounding bracket 17.

[0032] Fig. 5 shows a view of the interior of a portion of the sensor assembly 1. The top side of the lower PCBA 14 is visible. A sensor element 15 is arranged in a central hole of the lower PCBA 14. The sensor element 15 can be arranged concentrically with respect to the lower PCBA 14, wherein a gap can preferably be provided between the sensor element 15 and the lower PCBA 14. Wire bonds 16 can be provided to connect the sensor element 15 to the lower PCBA 14. The wire bonds 16 can bridge the gap between the sensor element 15 and the lower PCBA 14.

[0033] The grounding bracket 17 may be provided below and / or adjacent to the lower PCBA 14. The grounding bracket 17 may include at least one and preferably two grounding bracket tabs 18, which may be arranged on opposite radially outer portions of the grounding bracket 17. The grounding bracket tabs 18 may be inserted into the lower PCBA key slots 19 provided in the radially outer periphery of the lower PCBA 14.

[0034] Fig. Figure 6 shows another view of the interior of a portion of the sensor assembly 1. The grounding bracket tabs 18 are shown inserted into the lower PCBA key slots 19 of the lower PCBA 14. The grounding bracket tabs 18 fix the lower PCBA 14 relative to the grounding bracket 17. The grounding bracket tabs 18 can provide a snap-in connection between the grounding bracket 17 and the lower PCBA 14. The lower PCBA key slots 19 allow the outer diameter of the assembled lower PCBA 14 and the grounding bracket 17 to be kept to a minimum.

[0035] Fig. Figure 7 shows an exploded view of the internal parts of the sensor assembly 1. The lower PCBA 14 is shown next to the grounding bracket 17. As can be seen from the two components, the lower PCBA key slots 19 are arranged at positions that correspond to the positions of the grounding bracket tabs 18 of the grounding bracket 17. The grounding bracket 17 can be a ring-shaped, toroidal component. The lower PCBA 14 can be a circular and flat component.

[0036] Fig. Figure 8 shows another exploded view of the interior of the sensor assembly 1. Here, the lower PCBA 14 is shown from the underside. The underside of the lower PCBA 14 includes a PCBA ground connection part 20. The PCBA ground connection part 20 may itself comprise a number of preferably identical sub-parts arranged around the perimeter of the lower PCBA 14.

[0037] The grounding bracket 17 may have a matching grounding bracket connection part 21 that can be at least partially inserted into the PCBA grounding connection part 20. In the embodiment of the Fig. 7 and Fig. 8, the grounding bracket connection part 21 and the PCBA grounding connection part 20 comprise four preferably identical subcomponents, which are preferably arranged at, for example, 90° angles to each other and around the circumference of the respective component. In other embodiments, other suitable numbers of grounding bracket connection parts 21 and corresponding PCBA grounding connection parts 20 may be present.

[0038] The grounding bracket connection part 21 electrically connects the grounding bracket 17 to at least one of the PCBAs 13, 14 and / or to the capsule 3. The grounding bracket connection part 21 can be electrically connected to the lower PCBA 14, preferably soldered thereto. Alternatively or additionally, the grounding bracket 17 and / or the capsule 3 can be connected to the Fig. 3 shown media connector 5 electrically connected, preferably welded thereto.

[0039] Fig. Figure 9 shows a partially transparent view of the interior of the sensor assembly 1, showing the placement of the lower PCBA 14 and the grounding bracket 17 between the electronic connector 2 and the media connector 5. The capsule 3 can come into contact with the grounding bracket tabs 18 of the grounding bracket 17, so that the interior of the capsule 3 presses against the radial outer surfaces of the grounding bracket tabs 18. The grounding bracket tabs 18 are thus pressed against the lower PCBA 14 and / or the electrical connector 2.

[0040] Fig. 10 shows perspective views of the electrical connector 2 together with some other components of the sensor assembly 1.

[0041] Fig. 11 shows a perspective view of the electrical connector 2. The connector pins 8 are shown in a recessed portion of the electrical connector 2. The connector pins 8 can be arranged in any desired pattern. Embodiments with other numbers of connector pins 8 are also contemplated. The connector pins 8 can be arranged in a recessed portion defined by the annular seat 12.

[0042] The electrical connector 2 may include electrical connector tabs 25 for coupling the electrical connector 2 to other components of the sensor assembly 1.

[0043] The electrical connector 2 includes electrical connector key slots 27 for coupling the electrical connector 2 to other components of the sensor assembly 1.

[0044] The key slot 27 of the electrical connector 2 takes the e.g. Fig. 7. The key slot 27 of the electrical connector may be a recessed portion on an outer periphery of the electrical connector 2, into which the grounding retaining lug 18 may be at least partially inserted. In the embodiment of Fig. 11, two key slots 27 of the electrical connector are shown, which interact with two corresponding grounding support tabs 18. Embodiments with 1, 2, 3, or any other suitable number of connector key slots 27 and matching grounding support tabs 18 are also contemplated.

[0045] The key slot 27 of the electrical connector may be a recess to secure the connector 2 so that it cannot be rotated once inserted into the capsule 3 shown in other figures. Two caulked portions may be provided on the sides of the capsule 3, which press material of the capsule 3 into the connector key slot 27 to fix the capsule 3 to the connector key slot 27 in a caulking and / or crimping process.

[0046] The electrical connector's tab 25 is an alignment feature that ensures that the upper PCBA 13 and the upper PCBA key slot 26 are correctly aligned, especially during assembly. The electrical connector's tab 25 and the upper PCBA key slot 26 are not locking features. They merely ensure that the upper PCBA 13 is correctly rotated during assembly to enable a poke-yoke function. The features that secure the electrical connector 2 against rotation are the grounding retention tabs 18 and the connector key slot 27.

[0047] Fig. 12 shows an exploded view of a part of the sensor assembly 1. The upper PCBA 13 comprises one or more upper PCBA key slots 26, into which, for example, the Fig. The tab 25 of the electrical connector shown in Figure 11 can be inserted to secure the corresponding components together. This ensures that the upper PCBA 13 is correctly aligned during assembly, e.g., when soldering the connector pins 8. The upper PCBA 13 can be fully inserted into the capsule 3.

[0048] The tab 25 of the electrical connector and the key slot 26 of the upper PCBA secure the electrical connector 2 so that it cannot rotate and / or twist within the enclosure 3, and the electrical connector 2 is also locked to the PCBA 13, 14. Features 25 and 26 may therefore not be locking features, but rather only ensure that the PCBAs are correctly rotated during assembly. The features that secure the electrical connector 2 against rotation may be the grounding retaining tab 18 and the key slot 27 of the electrical connector.

[0049] Fig. Figure 13 shows a detailed view of the interior of the sensor assembly 1, wherein the grounding bracket 17 is connected to the lower PCBA 14. The lower PCBA 14 can be connected to the upper PCBA 13 via the PCBA connection holes 23 and the PCBA connector pins 24. In the embodiment of Fig. 13 shows a total of four PCBA connecting pins 24 and corresponding PCBA connecting holes 23. However, the number of PCBA connecting pins 24 and corresponding PCBA connecting holes 23 can be any suitable number of pins and corresponding holes. The connecting pins 24 space the upper PCBA 13 from the lower PCBA 14 and can establish an electrical connection between the components.

[0050] The lower PCBA 14 may include a lower PCBA key slot 19 for receiving the grounding retaining tab 18. The same grounding retaining tab 18 may therefore be inserted into the electrical connector key slot 27, the upper PCBA key slot 26, and / or the lower PCBA key slot 19.

[0051] Fig. 14 shows a detailed view of the capsule 3. The capsule 3 may be a substantially hollow cylindrical and / or toroidal component. The capsule 3 may comprise a crimped capsule portion 10 at its upper edge. It may comprise an inner annular capsule seat 11 on its radially inner side, preferably approximately midway between its upper and lower edges. The inner annular capsule seat 11 may be the only seat of the capsule 3. There may be no other seat and / or only a uniformly curved outer surface 22 on the outside of the capsule 3.

[0052] The outer surface 22 of the capsule 3 can have a uniform outer radius. The capsule 3 can comprise a lower cylindrical part with a uniform wall thickness, an upper part with a reduced and also uniform wall thickness, and the crimped capsule part 10.

[0053] The upper crimped capsule part 10 secures the electrical connector 2 to the capsule 3. The capsule 3 can be crimped in a radially inward direction once the electrical connector 2 has been at least partially inserted into the capsule 3, such as in Fig. 3. The electrical connector 2 may have a groove, a recess, or a shoulder, which preferably extends in the circumferential direction of the electrical connector 2. The upper crimped capsule part 10 can be crimped to this groove or shoulder of the electrical connector 2.

[0054] The lower cylindrical part facilitates the attachment of, for example, labels and / or the provision of engraved information such as text information on the capsule 3.

[0055] Capsule 3 can be a cold-drawn component. Cold-drawing the capsule 3 facilitates its manufacturing, while its uniformly cylindrical exterior provides a smooth surface for visual identifiers such as labels or engravings.

[0056] The invention also relates to a method for assembling the sensor arrangement 1. The method comprises the steps: Connecting the grounding bracket 17 to the media connector 5; Connecting the capsule 3 to the media connector 5; Inserting the PCBA 13, 14 into the capsule 3; and at least partially inserting the electrical connector 2 into the capsule 3.

[0057] The method may include additional or alternative steps. The assembly steps may depend on the features of the actual sensor assembly. Any features mentioned with respect to the sensor assembly may be assembled during the assembly process. The method steps may be performed in any logically possible order. The method may include partial assembly steps that may only provide parts of the sensor assembly 1.

[0058] The assembly process can be divided into three sub-assembly steps for assembling an upper assembly, a lower assembly, and the final assembly. The upper assembly can include the following steps: Mounting the PCBA connecting pins 24 in the upper PCBA 13; Placing the upper PCBA 13 into the electrical connector 2 and soldering the connector pins 8 to the upper PCBA 13; Mounting the O-ring 9 on the electrical connector 2; Pressing the electrical connector 2 into the capsule 3; and Caulking and / or crimping the upper edge of the capsule to become the crimped capsule part 10 to secure the electrical connector 2.

[0059] The below arrangement can include the steps: Welding the sensor element 15 to the media connector 5; Placing the grounding bracket 17 on the lower PCBA 14 such that the grounding bracket tab 18 engages the key slot 19 of the lower PCBA, and then soldering, preferably by reflow soldering, the grounding bracket 17 to the lower PCBA 14; Placing the grounding bracket 17, preferably with the lower PCBA 14 mounted, onto the media connector 5 and welding them together; and Wire bonding of the sensor element 15 to the lower PCBA 14.

[0060] Final assembly can include the following steps: Aligning and compressing the upper assembly onto or with the lower assembly such that the grounding retaining tab 18 engages the key slot 27 of the electrical connector and the capsule 3 sits on the media connector 5; and Welding the capsule 3 with the media connector 5.

[0061] An alternative assembly method may include alternative steps so that the capsule 3 is moved to the lower assembly and can be welded to the media connector 5 before the electrical connector 2 is pressed into the capsule 3.

[0062] Here the above arrangement can be the steps: Attaching the PCBA connector pins 24 in the upper PCBA 13; Placing the upper PCBA 13 into the electrical connector 2 and soldering the connector pins 8 to the upper PCBA 13; and Attaching the O-ring 9 to the electrical connector 2.

[0063] The below arrangement can include the steps: Welding the sensor element 15 to the media connector 5; Placing the grounding bracket 17 on the lower PCBA 14 such that the grounding bracket lug 18 engages with the key slot 19 of the lower PCBA, and then Soldering, preferably by reflow soldering, the grounding bracket 17 to the lower PCBA 14; Placing the grounding bracket 17, preferably with the lower PCBA 14 mounted, on the media connector 5 and welding them together; Wire bonding the sensor element 15 to the lower PCBA 14; and Placing the capsule 3 on the media connector 5 and welding them together.

[0064] Final assembly can include the following steps: Aligning and compressing the upper assembly onto or with the lower assembly such that the grounding retaining tab 18 engages the key slot 27 of the electrical connector; Pressing the electrical connector 2 into the capsule 3; and Caulking and / or crimping the upper edge of the capsule 3 such that it becomes the crimped capsule part 10 to secure the electrical connector 2.

[0065] The individual process steps can be performed in different sequences, where logically possible. Additional process steps related to providing the sensor arrangement currently described may also be part of the assembly process.
