    Description Title Device with a sensor and with an electric cable Prior art The invention is based on a device for mechanical connection and electrical contact of a sensor with an electric cable.
    According to the state of the art, low-pole electronic components are known, such as inertial sensors for safety systems, such as ABS or ESP, which are mounted by the vehicle manufacturer at the final assembly or alternatively by hand at the supplier in connection with the installation of the cable bundle. The assembly is usually done by single screwing the sensor directly on the vehicle body or alternatively with a single pre-assembly group. The electrical contacting of the sensor takes place in connection with its mechanical fixation in a further working step via a plug-in system.
    Description of the invention The object of the invention is to simplify the above-mentioned manufacturing steps and enable a simple integration of the sensor in the electrical cable and the cable bundle, respectively.
    The invention relates to a device with a sensor and with an electric cable, the sensor of which is housed in a housing. An advantage of the invention is that the conductor of the cable at certain places is exposed and the housing with the sensor at these exposed places of the cable is closed to the conductor of the cable in a material and / or form-fitting manner. In addition, an electrically insulating envelope is provided, which form-fitting surrounds the housing and at least covers the cable in the area of the housing.
    Due to the thus achieved integration of the sensor in the cable and the cable bundle, respectively, the plug-in contact terminals in the sensor housing and the housing of the matching connector can advantageously be omitted in the cable bundle. The sensor can then be placed at any place in the cable, alternatively also as a termination of the electrical cable.
    In the dependent claims, further advantageous designs and improvements of the device according to the invention are constructed.
    In one embodiment, the casing encloses the cable in the area of the housing, so that the cable is embedded in the casing.
    The material-tight connection of the sensor to the cable preferably takes place soldering, for example by reflow soldering, a soft soldering process, as it is preferably used for soldering so-called SMD ("Surface I / | ounted Devices") construction parts.
    An alternative form-fitting connection or integration of the sensor with the cable consists in that the conductors of the cable are provided with contacts, preferably with so-called crimp contacts, in which the housing or the so-called package is inserted, mechanically fixed and electrically contacted.
    In one embodiment, the electrical contacts of the conductors are made at these connection points as electromagnetic shielding, whereby an effective EI / IV protection can be realized simultaneously.
    The housing of the sensor is provided with an envelope, which preferably consists of a thermo-mechanically adapted duroplast. Thus, on the one hand, a durable and temperature-resistant and preferably tight wrap is produced. In addition, costly thermoplastic injection can be eliminated when using the thermoplastic injection.
    In one embodiment, seams provided with openings are produced at the same time as the elevation, which serve to receive fastening elements. The latter roofs, for example, can be designed as expander rivets, with the aid of which the housing with the sensor and the cable, respectively, are attached to the body of a vehicle.
    Drawing Figure 1 shows the principal construction of the device according to the invention according to a first embodiment, Figure 2 shows a disassembled representation of the construction according to Figure 1, Figure 3 shows the basic construction of the device according to the invention according to a second embodiment, Figure 4 shows a disassembled representation of the construction according to figure 3, and Figure 5 shows a cross section through the contacts and the housing with the sensor according to figure 3.
    Embodiment Figure 1 schematically shows the one with an electrical cable 2 mechanically and electrically connected to the sensor 4. The sensor 4 is embedded in a housing 18. The housing 18 is surrounded by an envelope 20. Figure 2 shows a disassembled representation of Figure 1. The one with an electrical In the present exemplary embodiment, the cable 2 provided with insulating sheath 6 has four conductors 8, 10, 12, 14. The cable 2 may, for example, be part of a cable bundle in a vehicle. The two centrally located conductors 10 and 12 are then closed to the material, for example by a soft soldering process, the above-mentioned reflow soldering, electrically and mechanically connected to the sensor 4 housing 18. In addition, solder paste 16 is applied to the conductor surfaces 50 of the two centrally located conductors 10. 12, after which the sensor 4 integrated in the housing 18 is connected to both conductors 10, 12. This overall connection is in turn tightly enclosed with the casing 20, which is made by spraying the cable 2 and the housing 18 with preferably a thermosetting plastic material. Instead of thermosetting plastic, other electrically insulating materials can also be used for the manufacture of the casing 20. The casing 20 covers at least the cable 2 in the area of the housing 18, so that the space between the housing 18 and the upper side of the cable 2 is sealed. In a further embodiment the cable 2 and with the housing 18 with the sensor 4 are embedded in the housing 20. In this case both the upper side of the cable 2 and also the underside of the cable 2 in the area of the housing 18 are covered by the housing 20. Preferably the housing 20 is designed so that at least the electrical contacts 51 and the contacts 34, 36, preferably the housing 18 with the sensor 4 and the contacts 34, 36, are tightly enclosed.
    The sensor 4 can in addition have an evaluation connection in the housing 18, in particular an ASIC connection. In addition, the housing with the sensor 4 can be designed as an LGA sensor, electrical contactors 51 (Fig. 5) being arranged on the underside of the housing 18 for electrical contacting, the sensor and the evaluation coupling, respectively. Thus, the housing 18 with the sensor 4 and the evaluation coupling can form a sensor chipset. The solder paste 16 can be formed in the form of solder paste pads.
    In the manufacture of the casing 20 by means of a corresponding injection mold, in the presented embodiment, lugs 22 and 24 developed simultaneously in one piece on the casing 20, in which corresponding openings for receiving the fastening elements 26 and 28 are arranged. When attaching the cable 2 to the body of the vehicle, the fastening elements 26, 28 designed as expanders engage in the corresponding openings of the body.
    In a second exemplary embodiment, which is described below with the aid of Figures 3 and 4, a sensor 4 integrated in a housing 18 is likewise fixed on an electric cable 32, in which case the two central electrical conductors 33 and 35 are located at one the end of the four-wire cable 32 provided with contacts 34, 36, into which the housing 18 of the sensor is inserted, mechanically fixed and electrically contacted. The contacts 34, 36 can be designed as crimp contacts.
    The housing 18 is in turn provided with a casing 20, which is preferably made by spraying with a thermosetting plastic material. Instead of thermosetting plastic, second electrically insulating material can also be used for manufacturing the casing 20. The casing 20 surrounds the cable 2 and the housing 18 with the sensor 4. In this case, the casing 20 can also enclose the top and bottom of the cable 2. The casing 20 has two lugs 40 and 42, which are produced by injection molding together with the casing 20. The welds 40, 42 have openings in which fastening elements in the form of two expander rivets 44 and 46 are accommodated, with which the auxiliary sensor and the cable 32, respectively, are attached to the body of the vehicle. The sensor 4 can also have an evaluation connection in the housing 18, in particular an ASIC connection. In addition, the housing 18 with the sensor 4 can be designed as an LGA sensor, electrical contacts (51 (Fig. 5) being arranged on the underside of the housing 18 for electrical contacting of the sensor and the evaluation circuit, respectively). .
    Figure 5 shows a schematic cross-section through the housing 18 with the sensor 4, whereby depending on the selected embodiment a evaluation connection, in particular an ASIC connection, can also be arranged in the housing 18. The housing 18 is mechanically fixed by the contacts 34, 36 and the sensor 4 is electrically connected to the contacts 34, 36 by electrical contacts 51, which are arranged on the underside of the housing 18. In addition, after the assembly of the housing 18, the casing 20 is preferably sprayed on with a thermosetting plastic material. In this case, the contacts 34, 36 and preferably the housing 18 are tightly enclosed. Instead of thermosetting plastic, other electrically insulating materials can also be used for the production of the casing 20.
    Preferably, the casing 20 is designed in such a way that at least the electrical contactors 51 and the contacts 34, 36, preferably the housing 18 with the sensor 4 and the contacts 34, 36, 51 are tightly enclosed.
    In the embodiment shown, each of the contacts 34, 36 has a bottom wall 54, a side wall 52 and a roof wall 53. The side walls 52 are formed perpendicular to the bottom wall 54 of the conductors 33, 35. The roof walls 53 are arranged parallel to the bottom wall 54 of the conductors 33, 35 and face each other. However, there remains a distance between the two-walled roof walls 53. The contacts 34, 36 form the bottom walls, the side walls 52 and the roof walls 53 a receiving space for receiving the housing 18. By means of the receiving space, the housing 18 can be mechanically held before spraying and the electrical the contacts 51 are electrically contacted with the bottom walls 54. By means of the casing 20, in particular the contacts 51 and the contacts 34, 36 are electrically insulated and are preferably sealed against moisture. Conductor contacts 34, 36 can be designed as crimp contacts 34, 36, whereby crimp contacts via a corresponding crimp mounting on the cable and on the corresponding conductors 33, 35 are fixed mechanically and electrically contacted.
    The receiving space also provides an EI / IV protection, as the housing 18 and thus also the sensor 4 and preferably also a provided evaluation device (ASIC) are shielded over a large area through the bottom walls 54, the side walls 52 and the roof walls 53.
    The sensor can, for example, be designed as a motion sensor, acceleration sensor or sominertial sensor for measuring an acceleration and a rotational speed, for example for safety systems such as ABS / ESP or airbag systems.
