Definitions
- the invention relates to an arrangement comprising a plug connector and a cable connected to it, which has an inner conductor, a shield, an insulation between the inner conductor and the shield and a jacket which surrounds the aforementioned components, with a Sleeve is inserted between the insulation and the shield and a tubular component surrounds the shield and the sleeve, according to the features of the preamble of claim 1.
- Such a configuration of an arrangement is useful in order to produce a continuous shielding from the cable to a plug connector or mating connector which is connected to the shielded cable.
- the sleeve is designed as a slotted component in order to enable the tubular component, which is designed as an outer sleeve, to be pushed on.
- the slotted component more precisely the slotted sleeve, has a bead
- the tubular component more precisely the outer sleeve, having a groove that matches the bead for fastening on the sleeve. Thereby the outer sleeve cannot be crimped onto the slotted sleeve.
- the fastening of the outer sleeve on the cable therefore leaves something to be desired. Furthermore, the sheath adjoins the braided outer conductor at an axial distance, so that there is no tightness and no fastening of the connector to the sheath of the cable and moisture can also penetrate.
- the invention is therefore based on the object of improving an arrangement of the type described at the beginning in such a way that the disadvantages outlined are eliminated.
- the cable with a connector but possibly also without such a connector, it should be ensured that tensile and / or compressive forces acting on the arrangement can be absorbed.
- the sleeve is designed as an unprotected support sleeve and that the tubular component is designed as an outer sleeve which, in addition to being shielded with a support sleeve, also surrounds a section of the jacket.
- the outer sleeve be designed as a crimp sleeve which is crimped onto the jacket and / or the shield with a support sleeve. In this case, crimping of the outer sleeve for the electrical connection between the support sleeve and the shield is produced at one point along the electrically conductive support sleeve.
- a second crimping of the outer sleeve which can be designed and adjusted independently, takes place, which creates strain relief from the cable material or sheath and thus enables functional relief of the shielding crimp point.
- This can prevent lateral or circular cable movements in the exit area from the cable directly affecting the Crimping zone between the support sleeve and the shield can affect.
- This type of support reduces the possible relative movements and forces between the outer sleeve, shield and support sleeve. This separate and therefore better protection against movement from the contact zone is of decisive importance for functional reliability.
- the first and the further crimp can be produced simultaneously in one step with one and the same tool (same crimp geometry) or simultaneously with two tools (same or different crimp geometries).
- the two crimps can be produced one after the other with one and the same tool or one after the other with two different tools. The same applies here with regard to the crimp geometries.
- the outer sleeve can have an inner collar which is arranged between the end faces of the outer sleeve and the support sleeve and extends around the shield up to the insulation.
- a distance can be provided between the end faces of the outer sleeve and the support sleeve.
- the shield can be introduced to a certain extent, in which the shield is in particular guided conically.
- the shielding extends to the outer, free end of the support sleeve.
- the support sleeve can also be designed as a crimp sleeve and crimped onto the insulation.
- the diameter of the section of the jacket as the seat of the outer sleeve and the outer diameter of the shield on the support sleeve are designed in such a way that they have the same dimensions.
- the shielding is thus implemented over the entire end of the cable, if necessary with a plug connection (plug connector and mating connector plugged together).
- plug connection plug connector and mating connector plugged together.
- the shielding for example a braided shield or a shielding foil
- a line for example a coaxial cable or a twisted pair line or the like
- This is necessary in order to transmit continuous shielding from the line via the plug connector to a mating plug connector, which is also connected to a shielded line, and therefore to loop it through.
- a connector of the generic type is known from DE 10 2009 016 227 A1.
- a connector for connection to a coaxial cable is described, which has an inner conductor, a braided outer conductor and insulation between the inner conductor and the outer conductor, as well as a protective jacket that surrounds the aforementioned components, with the Coaxial cable, a first tubular component is inserted between the insulation and the outer conductor of the coaxial cable and a second tubular component is positively connected to the first tubular component including the outer conductor, the second tubular component forming a sleeve open to the end section of the coaxial cable.
- the prior art uses a slotted inner sleeve - the sleeve according to the invention is rotationally symmetrical.
- the prior art only crimps the outer sleeve onto the screen - the sleeve according to the invention also crimps the cable sheath.
- the prior art does not crimp the outer sleeve, but only mounts it - there is no seal and no strain relief either. As a result, there is little or no strain relief for the connector via the shield.
- the crimping for the electrical connection between the sleeve and the screen is produced, for example, along the sleeve at one point.
- a second crimping that can be designed and adjusted independently, which only has to create strain relief from the cable material and thus enables functional relief of the shield crimping point. This avoids that lateral or circular cable movements in the exit area of the cable can have a direct effect on the crimping zone between the sleeve and the shield.
- This type of support reduces the possible relative movements and forces between the screen and the sleeve.
- the shielding is thus implemented over the entire plug connection (plug connector and mating connector plugged together).
- the invention thus relates to a shield contacting and strain relief concept, in particular for a single wire application.
- the support sleeve is mounted under the shielding, in particular a braided shield, of the cable, whereby the braided shield, contrary to the prior art, is not turned by 180 °, but runs straight in the axial direction of the cable, in particular in the plug-in direction of the connector.
- the outer crimp sleeve is crimped onto the cable jacket in order to guarantee additional stability with regard to strain relief and / or vibration and / or tightness.
- (Counter) connector with an electrically conductive housing in which at least one contact partner is arranged and which is arranged at one end of a line having a screen, characterized in that a support sleeve is provided, the support sleeve under the screen, in particular a braided screen, of the line and thus on the insulation of the electrical conductor of the line, whereby the braided shield, contrary to the prior art, is not turned over by 180 °, but runs straight in the axial direction of the line, in particular in the plugging direction of the connector, and also an outer one Crimp sleeve is crimped onto the cable jacket in order to guarantee additional stability in terms of strain relief and / or vibration and / or tightness.
- the construction principle according to the invention is not used in connection with a (counter) connector, but only in connection with the Line and / or when connecting the line or the (mating) connector to a housing of an electrical device.
- FIG. 1 two cables, the ends of which are designed according to the invention
- FIG. 2 a section through a cable with an embodiment of the invention
- Figure 3 a connector with attached cable and a mating connector
- FIG. 4 an arrangement according to the prior art.
- the reference number 1 denotes a cable which is designed as a coaxial cable in this embodiment and an inner conductor 2, a shield 3, an insulation 4 between the inner conductor and the shield and a sheath 5, which surrounds the aforementioned components.
- a tubular support sleeve 6 is arranged on this, which is designed to be annular without a slot.
- the support sleeve 6 is installed between the insulation 4 and the extended shield 3.
- the end of the jacket 5 facing the support sleeve 6 is offset and carries an outer sleeve 7 which also encloses the expanded shield 3 and the support sleeve 6.
- the outer sleeve 7 is designed as a crimp sleeve and encloses the end of the jacket 5 and the shield 3 together with the support sleeve 6 by means of crimps.
- the support sleeve 6 can also be designed as a crimp sleeve and fixed on the insulation 4.
- the outer sleeve 7 can be electrically conductive and with a housing 8 electrically (especially if the housing 8 is made of an electrically conductive material) and mechanically (regardless of whether the housing 8 is made of an electrically conductive material or an electrically non-conductive material exists) be connected, which can come into operative connection with a housing of a mating connector. It is particularly advantageous if the housing 8 and also the housing of the mating connector are made of an electrically conductive material, since this can ensure that the shielding is ensured across the plug connection formed by the connector and the mating connector.
- a free space 9 is provided in which the shield 3 is inserted between the end faces of the jacket 5 and the support sleeve 6, encompassing it.
- the outer sleeve 7 can also have an inner collar on which the shield 3 is placed, inserted, crimped on or the like, encompassing between the end faces of the jacket 5 and the support sleeve 6.
- the reference number 10 shows a locking element which is actuated after the plug connector and mating plug connector have been plugged together in order to prevent the plug connection from being unintentionally disconnected.
- a locking element 10 also referred to as a CPA
- This element 10 can consist of a plastic or a metallic material and generally only has a mechanical, but no electrical, function.
- the outer sleeve 7 has a reinforcement area 11 at its lower end (when looking at FIG. 3), which extends inwards and / or outwards over the cylindrical course of the outer sleeve 7 (in FIG inside than outside).
- a straight, cylindrical course an expansion, for example a conical or trumpet-shaped expansion or the like, can also be considered.
- This end area of the outer sleeve 7 is used to make its electrical connection, possibly also a mechanical connection in the sense of a guide, to a corresponding electrically conductive area of the mating connector in order to ensure the shielding across the plug connection.
- FIG. 4 shows an arrangement according to the prior art.
