Assessment unit 5 comprises (do not have detailed illustrate) evaluation electronics as important component part, and described evaluation electronics preferably includes microcontroller.Evaluation electronics by housing 13 encapsulate (in other words, by hermetically, namely watertight ground and preferably encapsulate airtightly) thus resist environmental concerns.Housing 13 in the illustrated example by two plastic components, namely by be also fixed with thereon the housing base 14 of evaluation electronics and basin shape, the lid case lid 15 be put on housing base 14 forms.Housing base 14 and case lid 15 are closed by welding, bonding or one or more sealing lip airtightly at this.Be communicated with lead-in wire 6 and 7 to contact, housing 13 is provided with corresponding plug-in connector 16 or 17.Another plug-in connector 18 is for connecting (do not have detailed illustrate) pilot, via described pilot, assessment unit 5 one aspect communicates with the controller of at least one outside, and via described pilot, necessary power delivery will be run to control unit 5 on the other hand.
Load bearing seat 8 is formed by the plastic components of the hull shape of single type, and described plastic components manufactures in injection molding method and/or hot-forming method.
Control unit 5 and load bearing seat 8 are twisted in the illustrated embodiment and are connect.But, described control unit also can otherwise, such as by riveted joint, bonding or be weldingly fixed on load bearing seat 8.Sensor electrode 3 and 4 is fixed on load bearing seat 8 respectively by elastomeric (maintenance) clip 19, and wherein said clip 19 single type ground is by the material forming of load bearing seat 8.Lead-in wire 6 and 7 is also fixed on load bearing seat 8 by load bearing seat 8 (maintenance) clip 20 that is shaped by elastomeric, single type.Therefore sensor electrode 3,4 and affiliated lead-in wire 6 or 7 press from both sides with load bearing seat 8 or clamp.Clip 19 and 20 is configured at this, and sensor electrode 3,4 without damage can be received by load bearing seat 8 together with affiliated lead-in wire 6,7---such as in order to change---.The size be set to respectively in load bearing seat 8 for the accommodation section of sensor electrode 3 and 4 is designed at this, and sensor electrode 3 and 4 is remained on load bearing seat 8 by the right edge appreciiable axial clearance 21 in FIG at load bearing seat 8 respectively.
Two sensor electrodes 3 and 4 abreast and install along longitudinal edge 22 below or along longitudinal edge 23 above with being spaced from each other distance.The basal plane 24 shown in Figure 4 of load bearing seat 8 is limited by the position of sensor electrode 3 and 4 at this.As described hereinabove, basal plane 24 is formed by following imaginary mathematics face, and two sensor electrodes 3,4 (or rather its axis) are arranged in described mathematics face.
Assessment unit 5 is at least similar to and is fixed between two sensor electrodes 3 and 4 in the center of area of load bearing seat 6.Assessment unit 5 is fixed on the dome-type forming section of load bearing seat 8 at this, and described forming section is referred to as mounting seat 25 hereinafter.As especially in figures 3 and 4 clearly, mounting seat 25 is saliently formed towards front side 10, and the basal plane 24 of assessment unit 5 towards front side 10 from load bearing seat 8 be placed in mounting seat 25 is given prominence to.Assessment unit 5 is approximately 3cm with the distance of the basal plane 24 of load bearing seat 8 when preferably designing the size of sensor assembly 1.Mounting seat 25 on the longitudinal direction of load bearing seat 8 by the shaping of the crimping shape in the material of load bearing seat 8 in both sides, described forming section is substantially for mechanical consolidation load bearing seat 8.
For the reason of manufacturing technology aspect, two are placed at its installation site middle finger to housing base 14 below for contacting the plug-in connector 16 and 17 being communicated with lead-in wire 6 and 7.Therefore, contact the lead-in wire 6 and 7 be communicated with assessment unit 5 also to stretch out first downwards from described assessment unit.Thus, two lead-in wires 6 and 7 intersect twice with the stretching, extension of sensor electrode 3 below---in the birds-eye view of front side 10---respectively, namely intersecting once for making lead-in wire 6 and 7 contact in the region of the socket connection be communicated with assessment unit 5, and in the continuation of corresponding lead-in wire 6 and 7 is stretched, intersecting another time.Therefore, the face of load bearing seat 8 exists two overlapping points 26, and at described overlapping some place, on the direction of observation transverse to basal plane 24, lead-in wire 6 is overlapping with sensor electrode 3.In addition, there are two overlapping points 27, at described overlapping some place, on the direction of observation transverse to basal plane 24, lead-in wire 7 is overlapping with sensor electrode 3.
Due to the specified criteria of geometric configuration, lead-in wire 6 and 7 puts 26 or 27 places especially near sensor electrode 3 in described overlap.At this, especially overlapping point 27 is crucial about electric noise, and at this overlapping some place, (being disposed in sensor electrode 4) lead-in wire 7 is overlapping with another sensor electrode 3, and in particular, going between 7 guides different electromotive forces usually from sensor electrode 3.By assessment unit 5 is bearing in mounting seat 25 in the mode outstanding from basal plane 24, guarantee at this, put the distance A1 (Fig. 3) for 3-4cm of 27 places formation approximately corresponding to minor increment in overlap between basal plane 24 (and then sensor electrode 3) and the lead-in wire 7 preset, but be under any circumstance not less than described minor increment.
Guaranteed by molded on the longitudinal edge 23 below load bearing seat 8, elastic bow-shaped 28 of joining in the intermediate space that formed between lead-in wire 7 and load bearing seat 8, lead-in wire 7 also can not be pressed against under the pressure load of outside that make near load bearing seat 8 (and then sensor electrode 3) can lower than minor increment.To this additionally or alternatively, elastic bow-shaped 28 for keeping the pilot that will be connected with plug-in connector 18.
Lead-in wire 6 and 7 itself closely abreast (when do not intersect each other or overlap) be laid on the front side 10 of load bearing seat 8.To this, lead-in wire 6 is laid under assessment unit 5, and go between 7 by (according in the view of Fig. 1 widdershins) to lay around assessment unit 5 and to be laid on assessment unit 5.Determined by clip 20 by 6,7 line routes be laid on load bearing seat 8 that go between accordingly along it, with going between 6,7 point-like accordingly (mode with discrete attachment point) is fixed on front side 10 by described clip.Lead-in wire 6 and 7 at least---is watched transverse to basal plane 24---by clip 20 and being laid between basal plane 24 and the outstanding installation site of assessment unit 5 with average level in the main portion of its length.
