Definitions
- the invention relates to a shielded connector with a first and a second housing part and disposed between them Sealing body.
- Such a shielded connector serves to provide a high screen attenuation also at interfaces between an electrical or electronic Device and the shielded cables to be connected to it to obtain.
- the housing parts of the connector have a conductive Surface on, with the shielding of the cables in electrical connection stands.
- the desired seal to get against the entry of dust and moisture is between the two housing parts usually used a rubber seal, which seals the interior of the housing parts from the outside.
- a rubber seal which seals the interior of the housing parts from the outside.
- the housing parts provided shield interrupted, so that additional measures are required to meet the required high levels To achieve screen attenuation.
- additional components, about sheet metal frame, used to be in spite of between the housing parts arranged rubber seal the required shielding attenuation or special housings can be used.
- the object of the invention is thus to provide a shielded connector of the type mentioned in such a way that both a high screen attenuation as well as a good seal over the exterior is achieved without special, costly measures should be taken.
- the sealing body consists of an electrically conductive material and is in electrical connection with at least one of the housing parts, and that the sealing body is an H-shaped profile with a central web, two inner webs and has two outboard webs. Due to the automatically formed by the sealing body electrical connection between the two housing parts a high shielding attenuation is achieved without additional components are required. At the same time, the sealing body ensures the required seal between the two housing parts against mechanical influences.
- the sealing body is an H-shaped profile with a central web, two inside Webs and two outboard webs has.
- Such a sealing body can interact with the housing parts in the manner of a labyrinth seal, what both the screen damping and the seal increased against mechanical influences.
- one of the inner webs of the sealing body with an extension is provided, which overlaps with the adjacent housing part.
- This extension serves to fix the sealing body relative to the corresponding Housing part and also acts as part of the labyrinth seal.
- At least one of the housing parts on its with the Sealing body cooperating end face has a projection, the in the groove between two opposite webs of the sealing body intervenes.
- the projection is used for reliable attachment of the Sealing body on the corresponding housing part and is also part of Labyrinth seal.
- the groove, in which engages the projection is dimensioned so that it to a dense plant comes to the projection.
- the groove is provided with a circumferential constriction, by means of the sealing body is held captive on the housing part. by virtue of the dimensions and the design of the groove results without additional Measures the desired seal between the sealing body and the corresponding housing part, so that the desired protection against mechanical influences is obtained.
- an O-ring is arranged between the the sealing body and cooperating with this end face the housing part is kept compressed.
- the O-ring used in the Groove of the sealing body protected against external influences is, improves the protection provided by the sealing body against mechanical Influences on the connector.
- the sealing body consists of a light metal alloy. This material selection allows due to the electrical conductivity of the material a high screen attenuation, while at the same time due to the ductility of the material a very good seal between the two housing parts is obtained, which may be without additional components to the desired protection against mechanical influences.
- a shielded connector is shown schematically. This includes a first housing part 10, a second housing part 12, an intermediate the housing parts 10, 12 arranged sealing body 14 and a Locking mechanism 16, by means of which the two housing parts 10, 12th can be connected to each other.
- the usually inside the two housing parts arranged components are not in the figures as they do not contribute to the understanding of the invention.
- the desired shielding of the connector is achieved by the first and the second housing part 10, 12 have a conductive surface.
- This conductive surface is either by applying a conductive Materials formed on the housing parts, if these are not one consist of conductive material, or housing parts are used, the consist of a conductive material.
- the sealing body 14 consists of a electrically conductive material, namely a light metal alloy.
- the first housing part 10 which in the embodiment shown, a mounting housing is, has on its the second housing part 12 facing End face on a circumferential projection 18.
- Sealing body 14 has an H-shaped profile in cross-section (see the figures 2 and 3).
- At the central web 20 of the sealing body close two outer Webs 22, 26 and two internal webs 24, 28 at. These are each circumferential, so that between the webs 22, 24 on the one hand and between the webs 26, 28 on the other hand in each case a groove 30 and 32 formed is (see also Fig. 4).
- an O-ring 34, 36 is arranged in each case in the case of each other mounted housing parts 10, 12 between the sealing body 14 and held clamped the corresponding end face of the housing parts becomes.
- the sealing body 14 acts with the two housing parts 10, 12 in the manner of a Labyrinth seal together by the projection 18 of the first housing part 10 engages in the groove 30 of the sealing body 14 and an on the inside Bridge 28 trained extension 38 with the first housing part 10th facing edge portion of the second housing part 12 overlaps.
- the way formed labyrinth seal ensures on the one hand a high Shield attenuation over a wide frequency range up to about 1 GHz and on the other hand, supported by the O-rings 34 and 36, a good mechanical Sealing between the two housing parts, with the IP degree of protection > 65 can be achieved.
- FIGS. 5 and 6 show a variant of that shown in FIGS Connector shown. As far as the components used here already is known from Figures 1 to 4, the same reference numerals are used; Reference is made to the above explanations.
- a significant advantage of the connector according to the invention is that formed in the manner described sealing body 14 without special Effort can replace the rubber seal, usually is used between the two housing parts of a connector. If this connector was previously shielded, now eliminated the measures that were needed to achieve the desired shielding attenuation despite using the rubber seal to achieve. If the Plug connector has not been shielded, he can now, if its housing parts are either provided with a conductive surface or off a conductive material, to a shielded connector be upgraded, since the existing of an electrically conductive material Seal body together with the two housing parts for the required Screen damping ensures. In both cases, the already existing Housing parts continue to be used, as described here Sealing body 14 is then used in the manner of a modular system, if it is required.
