Definitions
- the invention relates to a metallic connector housing according to the preamble of claim 1.
- Electrical cables for signal transmission are usually provided with a tubular shield made of electrically conductive material surrounding the signal conductors of the cable, on the one hand to prevent the influence of electromagnetic interference fields on the signal conductors and on the other hand to prevent electromagnetic radiation of the cable, which could interfere with neighboring cables or devices .
- a tubular shield made of electrically conductive material surrounding the signal conductors of the cable, on the one hand to prevent the influence of electromagnetic interference fields on the signal conductors and on the other hand to prevent electromagnetic radiation of the cable, which could interfere with neighboring cables or devices .
- umbrellas are formed by a metallic braid, which on one Signal conductor surrounding insulating jacket applied and in turn is surrounded by an insulating outer jacket of the cable.
- Such cables are often terminated by connectors, in particular plug connectors, in order to connect the signal conductors to other cables or to devices.
- connectors In order to prevent electromagnetic interference in the area of these connectors, such connectors are usually surrounded by a metal housing which is electrically connected to the shield of the cable.
- Connector end housings are often provided which are connected to the shield of the cable on one cable entry side and are fastened to the metal housing of the connector on the opposite side, for example by screwing.
- These connector end housings have a dual purpose. On the one hand, they serve as strain relief for the cable. On the other hand, they are used to bring the electrical potential of the cable shield to the potential of the metal housing of the connector.
- known connector end housings are provided with a sleeve part, on the outer circumference of which the screen is applied, while the remaining part of the cable is guided through the sleeve into the interior of the connector end housing.
- a sleeve part on the outer circumference of which the screen is applied, while the remaining part of the cable is guided through the sleeve into the interior of the connector end housing.
- An example of this is shown in DE-A-32 42 073.
- the screen braid In order to apply the screen to the outer circumference of the sleeve part, the screen braid must be opened so that it fits over the sleeve part. The area of the open screen pulled over the sleeve part is then crimped onto the sleeve part, there by means of a Tape or a clamp-like device attached or shrunk under a magnetic field.
- the connection can be released again if necessary.
- shrinking under a magnetic field the connection is no longer detachable and no longer allows repairs.
- the shield By opening the braid for the purpose of pulling it over the sleeve, the shield becomes electromagnetically leaky, so that the overall system containing this connector is susceptible to electromagnetic interference.
- a bushing device for the passage of a shielded electrical cable through a device housing in which an exposed end region of the cable shield is folded back onto a metallic sleeve pushed onto the outer jacket of the cable and. is fixed there by means of a crimp sleeve pushed over the retracted cable shield.
- a device for screwing a coaxial cable end to an amplifier housing with the features of the preamble of claim 1 in which the screen is connected to the sleeve only indirectly via a contact cage.
- the contact cage is located in a radial gap between the screen and an enlarged inner diameter of the sleeve.
- the contact cage extends with one axial end to the associated axial end of the sleeve.
- a contact cage acts like a slot radiator. That is, it emits high-frequency radiation and absorbs high-frequency radiation.
- the end region of the outer sheath of the cable located above the screen and adjoining the sleeve and contact cage cannot prevent such disruptive radiation and radiation.
- the contact cage must have a relatively strong spring force so that a sufficiently good electrical contact is made between the sleeve and the screen, even if manufacturing tolerances are to be expected.
- the dielectric of cables with particularly good high-frequency properties between the shield and the inner conductor often consists of relatively soft material, namely stretched and therefore microporous polytetrafluoroethylene (PTFE). This soft material is compressed radially inwards by the spring force of the contact cage. The result is a deformation of the cable structure at the point of the contact cage. This in turn leads to an undesirable change in the wave resistance of the cable at the point of the contact cage. This change in wave resistance affects high-frequency signals to be transmitted via the cable.
- the invention has for its object to provide a connection method by means of which the cable shield can be connected to a connector without the electromagnetic shielding effect and the electrical transmission properties of the cable being impaired.
- the solution consists in a metallic housing according to claim 1, which can be developed according to claims 2 to 12, as well as in a connector according to claim 13 and a connection arrangement according to claim 14 or 15, which can be developed according to claim 16 or 17.
- the screen of the cable does not need to be opened. Rather, the sleeve is pushed over the unopened screen. The screen and sleeve are then connected to one another electrically and mechanically, preferably by soldering or crimping a part of the screen which has been turned back onto the outer circumference of the sleeve onto the sleeve. The sleeve is then screwed to the metallic housing. This leads to a full-surface and positive connection of a direct type between the screen and the sleeve and thus to an electromagnetically tight connection. A wave resistance changing cable deformation also does not occur.
- connection method With this connection method, the screen retains its unchanged shape right into the sleeve. From the sleeve this and then the housing takes over the electromagnetic shielding. An electromagnetic leak of the shielding does not occur with this connection method.
- the outer part of the sleeve protruding from the sleeve and provided with an external thread is preferably provided on the diametrically opposite sides with flattenings, which make it possible to hold the sleeve in place with a spanner while the threaded nut is screwed on.
- the through opening of the housing is preferably adapted to this flattened outer contour of the outer part of the sleeve.
- the sleeve can have a stepped inner diameter in order to be able to accommodate not only the end region of the shield that has been freed from the outer insulating jacket, but also an end region of the outer insulating jacket.
- the transition area between the outer insulating jacket and the exposed screen is particularly protected.
- a cable kink protection sleeve is pushed onto the adjoining areas of the sleeve and the cable.
- This is preferably molded onto the nut, for example in the form of a plastic sleeve molded onto the nut, and extends with a conically decreasing diameter over part of the region of the cable adjoining the sleeve.
- the cable kink protection sleeve can also be molded onto the cable after the connector has been installed, preferably from the material from which the outer insulating jacket of the cable is made.
- a threaded nut with a sleeve-shaped extension is used, on which there is at least one anchor for the material of the cable kink protection sleeve. After the threaded nut has been screwed on, its sleeve-shaped extension is extrusion-coated at least on a part comprising the anchor and the outer insulating jacket with the cable kink protection sleeve. This provides an additional strain relief for the cable.
- the metallic housing can either be a connector end housing that is screwed to the metallic housing of a shielded connector.
- the metallic Housing can also be formed by the metal housing of the shielded electrical connector itself.
- the solution according to the invention is also suitable for so-called EMC hoses, ie shielded cables without content, the cable conductors or wires being drawn in later.
- EMC stands for electromagnetic compatibility.
- Fig. 1 shows the application of the invention in a metallic connector end housing, which in turn can be screwed onto the metallic housing of a connector, not shown.
- Fig. 1 shows a metallic housing 11 with a cable entry end wall 13, in which a passage opening 15 is formed.
- a sleeve 17 which has an outer part 19 protruding from the housing 11 with an external thread 21 and a radial flange 23 abutting the inside of the end wall 13.
- a threaded nut 25 is screwed onto the external thread 21, by means of which the side wall 13 and the flange 23 are fastened to one another.
- An outer insulating jacket 27 of an electrical cable 29 connects to the end of the sleeve 17 protruding from the housing 11.
- the cable 29 has a braided screen 31. This is exposed at the end of the cable by stripping a piece of the outer insulating jacket 27. The sleeve 17 is pushed onto the exposed screen 31.
- the sleeve 17 has a through opening 33 which is adapted to the outer diameter of the screen 31 so that the sleeve 17 can be pushed onto the screen 31.
- Fig. 2 shows an embodiment in which the sleeve 17 is soldered to the screen 31 after being pushed onto it.
- the length of the exposed part of the screen 31 is preferably dimensioned such that the free end of the screen 31 essentially closes with the flange-side end of the sleeve 17 when the sleeve 17 is fully pushed on.
- the flange 23 forms the axial end of the sleeve 17 pointing away from the outer insulating jacket 27.
- FIG. 3 shows an embodiment in which the sleeve 17 also has a sleeve extension 35 on the side of the flange 23 remote from the external thread 21.
- the screen 31 is freed from the outer insulating jacket 27 to such a length that the free end of the screen 31 can be turned around the sleeve extension 35 after the sleeve 17 has been completely pushed on.
- a crimp sleeve 39 is applied to the folded-over part 37 of the screen 31, by means of which the folded-over part 37 can be clamped onto the sleeve extension 35.
- insulated signal conductors 41 which protrude from the flange-side or sleeve extension-side axial end of the sleeve 17 and can be connected to contacts of a connector, not shown in the figures.
- Fig. 4 shows a perspective view of a particularly preferred embodiment of a sleeve 17, wherein the external thread 21 is not shown.
- This sleeve has two diametrically opposed flats 43, which are used to attack a wrench. So that the sleeve 17 can be held during the screwing of the threaded nut 25.
- Fig. 5 shows a housing 11, the passage opening 15 is adapted to the shape of the sleeve shown in Fig. 4.
- Fig. 6 shows a cable bend protection sleeve 45 made of plastic, which is molded or glued to the threaded nut 25.
- the cable kink protection sleeve 45 is indicated by dashed lines.
- connection arrangement first the cable anti-kink sleeve 45, then the threaded nut 25, or both as a unit, and then the housing 11 is pushed onto the free end of the cable 29, to the extent that the cable end for stripping the relevant insulating sheaths and for the cutting of the screen 31 is accessible.
- the sleeve 17 is pushed onto the exposed part of the screen 31 and soldered to it (FIG. 2) or firmly connected by means of the crimp sleeve 39 (FIG. 3).
- the housing 11 is then pulled off the cable until the end wall 13 stops on the flange 23.
- the threaded nut 25 is screwed onto the external thread 21 in order to tighten the end wall 13 between the flange 23 and the threaded nut 25.
- the cable kink protection sleeve 45 is pushed and glued to the threaded nut 25 if it does not form a unit with the threaded nut 25 anyway.
- the sleeve 17 has a stepped inner diameter. Between a larger inner diameter D1 at the cable insertion end of the sleeve 17 and a smaller inner diameter D2, which extends over the remaining axial length of the sleeve 17, there is a diameter step 51.
- the larger diameter D1 is adapted to the outer diameter of the cable 29 so that it can accommodate an end region of the outer insulating jacket 27 of the cable 29.
- the smaller inner diameter D2 is adapted to the outer diameter of the screen 31, so that the exposed area of the screen 31 can extend through the sleeve area with a smaller diameter D2.
- the end of the screen 31 can be aligned with the inner end of the sleeve 17 located in the housing 11 or, as shown in FIG. 7, protrude beyond the inner end of the sleeve 17.
- the threaded nut 25 is also modified. It has a sleeve-shaped extension 47 on the cable entry side, from the free end of which a radial armature 49 extends. This can be designed as a radial flange surrounding the sleeve-shaped extension 47 or in the form of a plurality of radially projecting teeth or barbs.
- the entire threaded nut 25, including its sleeve-like extension 47, is advantageously provided with an external thread. However, this is not absolutely necessary.
- a preformed cable kink protection sleeve 45 which is attached to the sleeve-shaped extension 47 and the anchor 49 has an adapted inner diameter profile and after screwing the threaded nut 25 from the cable 29 is pushed onto the anchor 49 and the sleeve-shaped extension 47.
- the anchor 49 can be provided on the side facing away from the housing 11 with a run-up slope in order to facilitate the pushing on of the cable kink protection sleeve 45, which in this embodiment consists of a flexible plastic.
- the same plastic material is preferably used from which the outer insulating jacket 27 of the cable 29 is made.
- the end of the cable kink protection sleeve 45 directed towards the housing 11 is axially spaced from the part of the threaded nut 25 abutting the housing 11.
- This type of cable bend protection sleeve 45 provides additional strain relief for the cable 29 in that the outer insulating jacket 27 is now connected to the metallic housing 11 via the threaded nut 25 and the sleeve 17 without the screen 31 having to bear the main tensile load. This results in a better force distribution under load, whereby the soldered or crimp connection between sleeve 17 and screen 31 is relieved. Furthermore, a stronger connection is achieved, also against vibration damage, since the nut cannot be loosened by vibrations but is held in place by the overmolded anti-kink sleeve 45. Better kink protection is also achieved.
- the cable anti-kink sleeve 45 produced by extrusion coating can also be released by cutting it obliquely between the head of the threaded nut 25 and the anchor 49, into the corner of the right angle between the anchor 49 and the sleeve-shaped extension 47, and then simply pulling it off. This means that even in this embodiment of a connector arrangement according to the invention, repair on site is possible. After the repair is complete, a shrink tube is simply applied over the outer insulating jacket 27 and the housing 11.
