Definitions
- the invention relates to a ner driving for producing an electrical component and the component itself.
- the invention relates in particular to the provision of sensor components, such as those used in motor vehicles for detecting various parameters, such as the ambient temperature.
- production has been carried out in a multi-stage ner driving, by first soldering connection elements with conductor paths of a circuit board on which the actual sensor element is mounted.
- a hinged connector housing was created using a plastic injection molding process. This housing was then placed in a final production stage around the printed circuit board and the soldered-on connection elements and, in contrast, firmly fixed by snapping it in place using a clip or the like.
- the soldering process, the formation of a separate connector housing and its assembly mean additional manufacturing steps which make the product more expensive, especially since these are products which have to be provided in large numbers.
- the invention has for its object to provide a ner driving of the type mentioned, which allows a more economical provision of electrical components of the type in question.
- soldering, welding or adhesive steps to create a permanent electrical connection between the connection elements and the conductor paths are to be avoided.
- the method is intended to enable the production of such electrical components that are largely shielded from harmful environmental influences.
- connection elements are held in an electrically conductive connection with the conductor paths of the circuit board without soldering, welding or gluing. The manufacturing steps previously required for this are accordingly saved.
- the molded plastic part created by the injection molding process naturally hermetically shields the connection point between the connection elements and conductor paths against environmental influences such as moisture. If desired, the entire printed circuit board, including the sensor element, could be embedded in the molded plastic part.
- An electrical component constructed in accordance with the invention comprises the construction features mentioned in claim 8.
- Fig. 4 is a sectional view taken along section line IV-IV in Fig. 3B.
- the sensor component comprises a strip-shaped printed circuit board or a base part 1 made of insulating material, such as a synthetic resin, on which conductor paths (not shown) made of electrically conductive material, such as copper, are applied or vapor-deposited in a suitable manner.
- a sensor element (not shown), which is in electrically conductive connection with the conductor paths, can be fastened to or near an axial end of the base part 1. Near the other axial end of the base part 1, a pair of through holes are provided, which contain eyes or eyes 4 made of metallic material, which are in electrically conductive connection with the conductor paths.
- connection elements or pins 5 are inserted into the eyelets 4 and protrude from a surface of the base part 1 at an angle, preferably a right angle.
- peripheral devices not shown, for example display devices or the like.
- the sole fixing of the connection elements 5 in the eyelets 4 is not sufficient in that they are pressed into the eyelets 4 in order to ensure a permanent electrical connection over longer operating times.
- FIGS. 2A, B the prefabricated part according to FIGS.
- connection elements 5 near the eyelets 4 in addition the eyelets 4 themselves and an adjoining area of the base part 1 come into contact with a melt made of a suitable plastic material when this is inserted into the injection mold to fill the mold.
- the injection molding of plastic material in the presence of inserts is basically known to the person skilled in the art and therefore does not need to be explained in more detail here.
- the aforementioned manufacturing step forms a plastic molded part on the part shown in FIGS. 1A, B, which has the general reference number 6 in FIGS. 2A, B and can be designed in any manner in its outer outline configuration. It is essential that the plastic material of the molded part 6 creates sufficient stability after the melt solidifies in order to permanently fix the mutual positional relationship of the connection elements 5 and the eyelets 4, so that shaking movements cannot make any changes to this fixation.
- the manufacturing step of molding the plastic molded part 6 on the base part 1 thus not only creates a “housing” that has a desired advantageous outline configuration, but at the same time secures the electrical connection of the connection elements 5 with the eyelets 4 or conductor paths and corresponds in this respect to those previously used for this provided soldering or the like.
- the part shown in FIGS. 2A, B can represent the final stage in the manufacture of the sensor component.
- a further plastic molded part is preferably molded onto the molded part 6.
- the other molded part bears the reference numeral 7 and creates a connector housing, which the exposed End regions of the connection elements 5 surrounds and can accommodate a plug (not shown) of a cable line.
- the further molded part 7 is molded onto the molded part 6 by inserting the part according to FIG.
- the plastic material can differ from the plastic material of the molded part 6 in at least one material parameter in order to achieve desired advantageous properties or effects.
- Material parameters can be the material composition, nature, color, hardness, temperature resistance, etc.
- a preferred plastic material for the molded part 6 is polybutylene terephthalate (PBT) and for the molded part 7 polyamide (PA). Other combinations of materials can also be provided.
- molded parts 6, 7 from different injection molding processes, only one molded part made of a suitable plastic material can be formed in one manufacturing step, which simultaneously permanently fixes the connection elements 5 with respect to the base part 1 and a connector housing with a configuration corresponding to the molded part 7 creates.
- FIG. 4 shows that a pair of connection elements 5 are embedded in the molded part 6 parallel to one another and are thus permanently connected to the eyelets 4. If desired, the connection elements 5 near the eyelets 4 can have enlarged areas 8 which improve the firm anchoring of the connection elements 5 in the plastic material of the molded part 6.
- connection elements 5 are preferably in the form of press-in connections (not shown) trained, which under the name AMP Action Pin from the company AMP Kunststoff GmbH, Amperestr. 7-11, D-63225 Langen / Germany.
- the molded part which permanently fixes the connection elements relative to the base part, is formed only in the area of the base part near the eyelets, the molded part can also embed the entire base part including the sensor element, if desired. It is further understood that each manufacturing step mentioned may involve the simultaneous production of a large number of parts.
