Description

Device for temporarily providing a cable termination with a

  broadband communication cable end. The invention relates to a device for temporarily providing a cable termination with one end of

  broadband communication cable, particularly of a resistor

  bridging tce between the inner and outer conductors

  laughing, the resistor being placed in a sleeve made of a material shrinkable under the effect of heat, which can

  be mounted hot on the cable sheath.

  Such a device is described for example in

  German utility model No. 81 21 847 of the Application-

  resse, which relates to a retractable cap comprising a

  resistance which is coated therein, the ends of which

  ducteur which protrude from the cap can be fixed,

  for example brazed, on the inner and outer conductors

  coaxial cable laugher The cap is then threaded

  above the solder and hot mounted on the cable sheath.

  A cable whip thus prefabricated can then

  be incorporated into cable taps The extremi-

  When the cable whips are closed, they protrude outwards and can be cut later, and when the network of communication cables is enlarged.

  broadband, cables to be added are connected

  strung there, high quality special couplings

being generally used.

  The object of the invention is to provide a solution

  tion with which such cable whips can

  be arranged so that when deleting the re-

  bridging resistance, we immediately obtain a

  coupling for the connection of a cable end

  respondent. With a device of the type indicated above, this problem is solved according to the invention thanks to the fact

  inside the sleeve is arranged a cover element

  two-sided range and that the jumper resistor in the use position is connected to one side and the free end of the broadband communication cable to the other

side of the coupling element.

  The invention makes it possible on the one hand to obtain that

  cable whip level, there is already the cover element

  range required for coupling, without requiring subsequent installation work for this purpose The coupling element is located inside the retractable sleeve and

  is therefore very largely protected vis-à-vis

  surrounding fluences and similar phenomena.

  From a constitutional point of view, the invention

  provides that the bridging resistance in the use position

  the layout is arranged at a short section of

  ble inside a non-shrunk region of the sleeve.

  Thanks to this constitution, it is possible to arrange the coupling so that it can receive identical elements on both sides, regardless of the direction

  mounting, i.e. bare coaxial cable ends

  dice and offset accordingly, regardless of whether a cable represents a small section of cable with

  a bridging resistor or a cable for the circuit used

  or for the branch circuit or a semi- circuit

  blable. According to the invention, it is also intended that

  the non-retracted region is in the form of a capu-

  chon closed; it may in particular be expected that the resistance

  is attached to the head of the cap, the head of the cap can

  before being separated from the remaining non-retracted region for

remove the resistance.

  It can be beneficial, as provided for

  the invention, that the dividing line to remove

  the resistance with the cap head at the level of the

  non-retracted area is made visible to the user by a marker It can be a colored ring, a

  imprint or intaglio or similar sign.

  Basically a tear or separation wire

  could also be incorporated or similarly placed

  ble in the material at this location.

  The closure of the cap can be continuous, that is to say that the sleeve of shrinkable material under

  the effect of heat is closed in itself in this re-

  gion It can however also be in the form of a pipe, a remaining part of the sleeve being able to be mounted hot on for example a support element for the resistance to form the cap, so that from the point

  functionally, a closed sleeve is formed.

  According to the invention, it is also provided that after removal of the bridging resistance with the

  small section of cable and the head of the cap, an

  The coaxial cable can be threaded into the free side of the coupling element and the sleeve region which has not yet been shrunk can be mounted hot on the threaded element. The invention makes it possible to manufacture whips of

  cable at the factory with very simple means Thus, the pro-

  ceded is arranged so that inside a piece of pipe or a sleeve of shrinkable material under the effect of heat, substantially in the middle, is placed a coupling element on two sides and this region be treated

  thermally, i.e. be hot mounted on the element

  coupling, whereby sleeve regions which are not yet retracted, i.e. regions which have a diameter much larger than that of the central region, are available on both sides Then a section of correspondingly shifted broadband communication cable can be introduced from one side, and the corresponding region can be hot-mounted on the cable sheath, while on the other side a short section of cable with resistance

  bridging, in this case only the extreme region of the

  non-shrunk tie being heat treated to form

  the cap closed, so that it tightens on the element

  resistance support by forming a cap.

  For the user, there remains at least one region per

  tial of the sleeve, in which in this state is the bridging resistor, which is not retracted, so that after removing the cap and threading for example another cable end, zette retractable region

  is available for the user circuit.

  The invention will be better understood using the

  following description of a preferred embodiment but

  nonlimiting, shown in the accompanying drawing, in which the single figure is a partially sectional view of a

device according to the invention.

  Inside a sleeve 1 made of shrink material

  table under the effect of heat is first mounted hot a coupling element 2 for coupling ends

  coaxial cables or communication cable ends

  broadband such a cable end 3 is indi-

  quée on the right half of the figure On the left half of the figure, the sleeve 1 is not yet retracted in

  this region, while the dotted line on the me-

  right side of the figure also represents the sleeve 1

retracted in this region.

  In the other end of the coupling element 2 is introduced a short section of cable 4 From the point of

  functional view, it has the same constitution as the cable 3.

  This short section of cable is equipped with a bridging resistor 5 which is supported by a resistance support

6 in synthetic material.

  As can be seen on the left side of the figure, the resistance support 6 slightly protrudes from the sleeve 1 when the latter is hot-mounted on the resistance support 6 in the external region 7 to form a

  cap A reference line 8, which can for example

  ple be printed or notched or similarly shaped, indicates to the user the location at which the head

  cap, designated 9 for simplicity, can be se-

  trimmed by a cut When this is the case, the cap head 9 with the resistance support 6, the resistance 5

  and the short section of cable 4, can be removed from the coupling

  ge 2, so that another cable end can be inserted

  troduite by the side We see that it remains in use

  device of a non-retracted region 10 of the sleeve 1

  which can be hot clamped on the cable sheath of the element

ment introduced.

  Naturally, the example of embodiment described can still be modified from many points of view without departing from the scope of the invention. Thus, for example, the head

  cap 9 can be an integral part of the sleeve 1.

  The coupling element 2 can be produced differently.

  The invention is also not limited to an application to broadband communication cables or to coaxial cables. Other ranges of application are possible, for example in the field of cables traversed by current or also others. pipes, like pipes

  water, hydraulic fluid or other fluids.

  As it goes without saying, and as it results from

  their already from the above, the invention is not limited to

  Lement to those of its embodiments and application which have been more especially envisaged; she embraces it,

on the contrary, all variants.
