Definitions

  • the invention relates to a connecting device for a coaxial cable, with an outer sleeve, which has a constrictable first section for attachment to the exposed shield of the coaxial cable, a second section for receiving an insert part and a constricting further section at its rear area, adjacent to the first section has which can be clamped on the outer jacket of the coaxial cable.
  • the usual connectors for coaxial cables e.g. B. antenna cables consist of several screw parts that are screwed apart for mounting on the coaxial cable.
  • the rear screw is z. B. pushed over the cable jacket and on the front screw part, the previously stripped and exposed on a portion of its length with the shielding coaxial cable, so that the cable core can be inserted into the insert part, while the shield with a shielding jacket of the first screw part in contact is coming.
  • the connector is clamped to the cable jacket.
  • the assembly of such connectors is time consuming.
  • a further disadvantage is that the two screw parts are only insufficiently clamped to the coaxial cable, so that the plug connector can be stripped off the cable end relatively easily. Since the connector consists of several loose parts, some of these parts can fall off or get lost during assembly.
  • connectors with a metallic outer sleeve which is deformed with crimping pliers and pressed against the exposed shielding of the cable.
  • the outer sleeve contains an insert part, from the front end of which a plug or a socket protrudes, and the rear end of which is used to insert the core of the coaxial cable.
  • Such a connector is due to the fixed contact pressure.
  • a secure contact between the outer sleeve and the shield is made between the shield and the deformed outer sleeve, but the strength of the mechanical connection between the outer sleeve and the coaxial cable is often insufficient.
  • Another disadvantage is that the outer sleeve is primarily attached to the shield of the coaxial cable, which in turn is not very strong and can tear under mechanical stress.
  • a known connecting device of the type mentioned at the beginning serves to connect a coaxial cable to a body which has a tubular socket for the passage of the cable core.
  • the shield is pulled over the socket and the tubular sleeve is squeezed over the shield and socket, as well as over the front end of the cable jacket with a deformation tool and in z. B. brought hexagonal shape.
  • the outer sleeve is firmly connected to the cable jacket and at the same time to the body to be connected.
  • the connector housing is made up of several separate parts, one of which is deformable.
  • Such connection connectors are complex and expensive.
  • Terminal connectors (US-A-2 786 095) are also known which have a tubular part for inserting the end of a coaxial cable. A rotatable sleeve with an internal thread sits on the tubular part. Cable sheath and shielding are pushed onto the end of the tubular part and a separate ring is crimped over with a pair of pliers. Such a connector consists of a total of three parts, the required insulating insert not being included.
  • the invention has for its object to develop a connecting device of the type mentioned in such a way that it can be used as a connector that has a simple and inexpensive to manufacture and ensures safe contact between the outer sleeve and the cable shield.
  • the invention provides that in a connector the insert, which is clamped in the second section before inserting the cable end into the connector, consists of insulating material and has a resilient contact device for contacting the cable core inside the outer sleeve and that Outer sleeve at the front end has a third section projecting beyond the insert part for enclosing a plug part protruding coaxially from the insert part.
  • the essentially cylindrical outer sleeve has two areas which are pushed onto the end of the coaxial cable, the narrower area surrounding the shield and the further area surrounding the cable jacket.
  • a shoulder results between the two sections, against which the front edge of the cable jacket abuts when the coaxial cable is inserted into the connector. This ensures that the cable sheath cannot be inserted into the narrower first section of the outer sleeve at all.
  • the further section of the outer sleeve which engages the cable sheath absorbs the main part of the tensile force, so that the shield is neither damaged nor loses its contact with the likewise constricted first section.
  • the first and the further section are deformed by squeezing to form pinch folds, the pinch folds of both sections being offset from one another by an angle, as seen in the end view.
  • the individual sections can be squeezed off when the plug connector is mounted on the coaxial cable using conventional crimping pliers or crimping pliers, the sections being squeezed one after the other.
  • the first and the further section are deformed in a polygonal shape, the edges of these sections being offset at an angle from one another, as viewed from the front. Due to this polygonal deformation, the squeezing forces are distributed relatively evenly over the circumference of the cable jacket and the shield.
  • a crimping pliers can be used to carry out the deformation, the tools or jaws of which have two successive stepped recesses which, when the jaws are pressed together, result in a stepped polygonal opening.
  • the connector shown in Figure 1 is a plug part, i. H. a part that interacts with a plug socket or is inserted into the plug socket.
  • the socket can be at the end of a coaxial cable or on a housing, e.g. B. an amplifier, an antenna switch or the like.
  • the plug part has an outer sleeve 10, which in succession has a first section 11 for receiving the shield 15 of the coaxial cable 16, a second section 12 in which the insert part 17 is fastened, and a third section 13 which projects freely from the insert part 17 Surrounds pin 18 at a distance.
  • the insert part 17 consists of a plastic body with an axial bore in which the rear end of the plug pin 18 is fastened. From the connector pin 18 protrude from the rear terminal legs 19, which are located in the through axial bore of the insert part 17. Between the terminal legs 19, the core 20 of the coaxial cable 16 stripped at its front end is inserted, so that a secure contact between the core 20 and the plug pin 18 is ensured.
  • the jacket of the outer sleeve in the second section 12 is pressed in at two points 21 opposite one another.
  • the coaxial cable 16 has a shield 22 coaxially surrounding the cable core 20 from a braid or a conductive foil. There is an insulation layer (not shown) between the cable core 20 and the shield 22.
  • the shield 22 is surrounded by a cable sheath 23 made of a relatively strong plastic.
  • the cable core 20 is exposed over a first length.
  • the shield 22 is exposed, so that the cable core 20 protrudes axially beyond the shield 22 and the shield 22 in turn protrudes towards the front end of the cable jacket 23.
  • the cylindrical further section 14 At the rear end of the first section 11 is connected via an oblique annular shoulder 24, the cylindrical further section 14, the diameter of which is greater by approximately the thickness of the cable sheath 23 than that of the first section 11.
  • FIGs 5 and 6 show a connector socket that can be coupled to the connector part of Figure 1.
  • the outer sleeve 10 ' has the four different sections 11, 12, 13, 14, the two adjacent sections 11 and 12 having the same diameter.
  • the socket sleeve 28 is fastened, which projects freely outwards from the insert part 17 and is arranged coaxially in the third section 13 of the outer sleeve 10 '.
  • the socket 28 serves to receive the plug pin 18 from FIG. 1, while the third section 13 of the plug part of FIG. 1 fits into the third section 13 of the plug part of FIG.
  • the third section 13 can contain an inserted ring-shaped spring part.
  • the coaxial cable 16 is also stripped in the device according to FIG. 5 in the manner shown in FIG. 2, so that the cable core 20 is exposed in a first section, the shield 22 is exposed in a second section, while the cable jacket 23 encloses the remaining part of the coaxial cable .
  • the sections 11 and 14 of the outer sleeve 10 have been deformed in a polygonal shape after the end of the coaxial cable has been inserted, as shown in FIG.
  • the type of deformation of the outer sleeve made of metal depends on the type of deformation tool used.
  • a hexagonal deformation, as shown in FIG. 6, is particularly expedient.
  • the edges of the two hexagons, which are formed by sections 11 and 14, are offset from one another, so that the hexagons are arranged on a gap.
  • the crimping pliers 30 shown in FIG. 7 serve to simultaneously deform the sections 11 and 14.
  • the jaws 31 and 32 of the crimping pliers 30 have trapezoidal depressions 33 which, when the jaws 31, 32 are closed, complement one another to form a hexagon.
  • the troughs 33 are divided into two sections 34, 35, which have different depths and are separated from one another by a shoulder 36.
  • the two rear sections 11 and 14 of the outer sleeves 10 and 10 ′ are squeezed from an originally round shape to a now hexagonal cross-sectional shape whereby the wall of the metal sleeve in section 11 comes in firm contact with the shield and in section 14 comes in firm contact with the jacket of the coaxial cable 16.
