Definitions

  • the invention relates to a plug part of a BNC connector for a coaxial cable, which has an outer and an inner conductor, with a plug body, which is an outer in relation to the direction of insertion Contact part, an electrically conductively connected to the outer contact part, rear connection area for fixing the outer conductor of the coaxial cable and an internal insulating member which has a central opening for receiving a contact pin to which the inner conductor of the Coaxial cable is connectable, and with a rotatable on the connector body stored bayonet sleeve.
  • a coaxial cable consists of a cylindrical inner conductor, mostly made of copper, one also arranged cylindrically around this conductor Insulator, usually made of polyethylene or Teflon, and also coaxial over it arranged conductors, preferably made of silver-plated copper braid or made of foil (braided shade or foil shade).
  • a coaxial cable with one connector or with another coaxial cable are different connector systems known, of which the so-called BNC connectors are the furthest are common.
  • the plug part is locked with the plug socket through a bayonet catch. On the one hand, this can be rotated by one Bayonet sleeve mounted on the plug body of the plug part.
  • the cylindrical housing of the socket has two opposite, pins protruding radially from the housing circumference.
  • the bayonet sleeve over these pins can be pushed onto the housing of the plug socket and rotated with it latched.
  • a BNC connector is for example in DE 197 23 050 C2.
  • Such BNC connectors have proven themselves millions of times and are very solid and mechanically robust. Especially with modern devices, for example Video cameras with a large number of connectors and actuators relatively narrow space is, however, that at the front end of the Plug part arranged bayonet sleeve due to the neighboring standing in the way Plug or other actuators difficult to reach. The Opening or closing the BNC connector is therefore for the user only possible with difficulty.
  • the object of the invention is to provide a plug part of a BNC connector at the beginning to provide the type mentioned, which, especially in confined spaces, easier to operate to open or close the connector is.
  • this is achieved with a plug part of the type mentioned kind in that furthermore an actuating sleeve designed as a separate part is provided, which is rotatably connected to the bayonet sleeve and protrudes the connection area of the plug body on the back, and over which the Bayonet sleeve can be operated to open and close the BNC connector is.
  • the actuation area of the plug part according to the invention no longer on the front End of this connector part, which makes operation much easier.
  • the actuating sleeve To the Connection of the coaxial cable to the plug part according to the invention becomes the actuating sleeve first pushed over the connection end of the cable and subsequently connected the cable to the plug part in the usual way.
  • the non-rotatable connection between the actuating sleeve and the bayonet sleeve is preferably a type of snap lock between the actuating sleeve and the bayonet sleeve or a non-rotatable one connected part provided.
  • the actuating sleeve in the coaxial cable overhanging its area adjacent to the plug part. This makes the Actuating sleeve at the same time as a cable protection sleeve to prevent the cable from kinking directly at the rear end of the connector body.
  • the embodiment shown in the figures of an inventive Connector part of a BNC connector for a coaxial cable that connects an external and has an inner conductor comprises a plug body 1, on which a bayonet sleeve 2 is rotatably mounted.
  • the bayonet sleeve 2 has in a conventional manner opposite grooves 3 on their inside, to which slots 4 connect.
  • the bayonet sleeve for training a bayonet lock over the opposite, radially from a cylindrical Protruding pins of the connector can be pushed on and lockable with the plug socket.
  • the connector body 1 has a front in relation to the direction of insertion outer contact part 5, with a connection area lying on the rear of the plug part 6 is electrically connected.
  • This connection area 6 is formed in the form of a crimp approach in the exemplary embodiment shown, on which the outer conductor of the coaxial cable can be pushed and by means of a Crimp sleeve 7 can be fixed by crimping.
  • Inside the connector body 1 an insulating part 8 is arranged inside the connector body 1 . This has a central opening 9.
  • the Contact pin After the inner conductor of the coaxial cable is soldered into a contact pin 10, the Contact pin inserted into this central opening 9 of the insulating part 8 and clicks into place in this one (at the same time the stripped outer conductor is crimped over the trained connection area 6 and then by crimping the crimp sleeve 7 fixed).
  • the connector body 1 further comprises an outwardly projecting, annular Flange 11.
  • This flange 11 is from a rear, adjoining a step 12 Area 13 of the bayonet sleeve 2 protrudes.
  • a clamping sleeve 14 has also an outwardly projecting annular flange 15. This Clamping sleeve 14 can be pressed into the rear area 13 of the bayonet sleeve, wherein the outer edge of the flange 15 is clamped to the inner wall of the Area 13 of the bayonet sleeve 2 abuts.
  • an axial spring 16 is provided, which on the opposite one another Side surfaces of the two flanges 11 and 15 supports and the bayonet sleeve in the rearward shifted position in which the step 12 abuts the flange 11, biases.
  • the clamping sleeve 14 also has its cylindrical end in the region of its rear end Opposing, circular recesses 17 and around 90 ° offset from it, starting from its rear edge, slot-shaped recesses 18. These recesses 17 and 18 serve for the rotationally fixed connection of the clamping sleeve 14 with an actuating sleeve 19. Die For this purpose, actuating sleeve 19 has inwardly projecting lugs 20, which in the circular recesses 17 of the clamping sleeve 14 can be snapped into place, and further inwardly projecting projections 21, which in the slot-like recesses 18 can be inserted and an anti-rotation device with respect to the clamping sleeve 14 form.
  • the bayonet sleeve 2 can be opened and opened via the actuating sleeve 19
  • the BNC connector can be closed.
  • the Actuating force is the actuating sleeve 19 on its outside with knurling or similar shape.
  • connection of the outer conductor of the coaxial cable can also be provided in a manner other than crimping, for which the connection area is to be trained in a correspondingly modified manner.
  • connection area is to be trained in a correspondingly modified manner.
  • connection area is to be trained in a correspondingly modified manner.
  • the non-rotatable Connection between the actuating sleeve 19 and the bayonet sleeve 2 could be done in a different way than the one shown, for example via a threaded connection, by sticking together or by shrinking.
  • Connection via the clamping sleeve 14 could also be a direct connection the actuating sleeve with the bayonet sleeve 2 may be provided.
