FIELD OF THE INVENTION The present invention relates to a plug for an electrical plug connection.
BACKGROUND INFORMATION In known plugs of this kind, a sealing mat, or rather matting seal (e.g. a rubber mat or a gel mat) is provided for the protection of the contacting locations of the plug. For this purpose, the contact pins, that preferably have a round cross section, of a mating connector are sealed by the sealing matting applied in the plug in response to the introduction of the mating connector. It is prevented thereby that, for example, water is able to reach the contacting locations from the mating connector via its contact pins, and trigger corrosion there. In order to obtain this sealing mat as a sound sealing element within the meaning of a complete sealing, in spite of contact pins having pierced through it, elastic material (such as rubber) or material that continues to flow (such as gel) is used for the sealing mat, and the sealing or the material that continues to flow is supported using a pressure plate. The sealing matting is clamped in place between the contact carrier's upper part of the plug and the pressure plate which is latched to the upper part of the contact carrier. The electrical contacts of the plug are provided on the contact carrier's lower part, which is connected to the upper part of the contact carrier. Therefore, the plug always has to be equipped with the pressure plate, in order for the sealing mat to be held to the upper part of the contact carrier, that is, in order to be present in the condition in which it can perform its function. From this, there follows an additional material and assembling expenditure in the production of such a plug. Additional tools and assembly steps are also required for the production of the pressure plate, which, together with the assembly, represents a considerable additional expenditure.
SUMMARY OF THE INVENTION The plug according to the present invention has the advantage that the function of the present pressure plate is integrated into the upper part of the contact carrier, and thus one may do without an additional pressure plate. Production costs and assembly costs as well as the number of individual parts of the plug connection can be reduced thereby.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an exploded illustration of the plug according to the present invention.
DETAILED DESCRIPTION FIG. 1 shows a plug 1 for an electrical plug connection of an electronic control unit in exploded form. Plug 1 has a contact carrier 4 made up of an upper part 2 and a lower part 3 plugged together, as well as a matting seal 5, which is compressed between upper and lower parts 2, 3. Lower part 3 is plugged into upper part 2, and is latched to upper part 2 with the aid of lateral latching arms 6. Upper part 2 and lower part 3 have plugging chambers 7, 8 that are aligned with one another, electrical contacts 9 (FIG. 2) being provided in plug chambers 8 of lower part 3. Upper part 2 has an upper-side plug accommodation 10 for a mating connector (that is not shown), whose contact pins reach through plug chambers 7 of upper part 2 and corresponding openings 11 in matting seal 5, and contact electrical contacts 9 in lower part 3. Matting seal 5 (e.g. a rubber mat or a gel mat) is used for sealing chambers 8 of lower part 3 and the contact pins of the mating connector that are plugged into these.
