Description

The present invention relates to a terminal of

connector for a coaxial cable.

  In the prior art the connectors of

  Coaxial cables are expensive to produce and usually require

  special tools and welding for

  attach the connector to the cables, or the cables must

  be specially prepared to receive the connec-

  tor. The present invention improves the solution to these problems by providing a connector that is less expensive to produce than existing connectors, that does not require special tools to attach to the cable and that is faster and easier to connect to the cable.

than existing connectors.

  In a broad manner, the subject of the invention is a coaxial cable connector comprising: a central contact adapted to be connected to the central wire of the coaxial cable, a second contact adapted to connect to the braid, and a suitable external element for sliding on the wire casing, characterized in that in the assembly position, said second contact is isolated from said first contact and said outer member secures the

braid at second contact.

  In its preferred embodiment, the invention

  provides an advanced coaxial cable connector

  characterized in that the connection to the coaxial cable does not require the use of special crimping tools, nor the use of rotating assembly devices such as

only nuts.

  According to a preferred embodiment, a

  central contact is adapted to engage and imprison-

  the central wire of the coaxial cable. A second insulated contact of the central contact is adapted to connect to the braid by sliding below or above the braid.

  An outer member preferably having a cavity

  conical tee slides on the wrap of the wire, which has the effect that, in the assembly position, the second contact is isolated from the first contact and traps the first contact on the central wire and that said outer member

  imprison the said braid on the second contact.

  It results several advantages of this realization.

  One of the advantages is that only one cut is enough

  health to strip the central thread. Another advantage is that no special crimping tool is needed and

  the attachment of the external element to the connection

  only an axial displacement without any movement

significant rotation.

  The invention will be described below by means of an example with reference to the appended drawing which represents

  a sectional view of an embodiment of the invention.

  The coaxial connector of the preferred embodiment of

  comprises a central contact 6 having its end shaped with teeth surrounding a recess in

  which the central wire of the coaxial cable can be adjusted.

  The teeth can be of any suitable form but in the embodiment shown, they each have a

  projecting section 18 adjacent to the end 15.

  central tact 6 is maintained by an insulating section 7

  which also adapts to the second contact 8.

  This second contact 8 has a conformation in two

  - longitudinally slotted parts with its guiding end

  mat 14 developing outside the insulation.

  The second contact 8 is held in position by a sleeve 9 by means of reliefs 11 and 12 extending from the second contact 8, which engages here from

  and other of the projection 13 of the sleeve.

  An insulating sheath or an outer member 10 with a conical cavity is then applied to the second

contact 8 cleared.

  To connect the connector of this in-

  to a coaxial cable, it is necessary that the

  cable 1 is exposed to disengage the core wire 5.

  Only one cut is sufficient compared to the connections

  in the prior art in which both

  the center wire and the braid must be separated

  is lying. The sheath 10 is slid over the wire 1 and pushed out of the connection zone. The central contact

  6 is slipped on the central wire 5 released. A room

  spun, containing the second contact 8 and the insulator 7 is then slid over the contact 6. The guide end 14 of the contact 8 slides between the braid 3 and the layer

  insulation 4 or between the braid 3 and the insulating layer 2.

  When the profiled piece is pushed into its housing, the connecting end 15 of the contact 6 snaps securely onto the central wire 5 thanks to the conicity of the second contact 8 and to the shape of the insulator 7 in the adjacent part at the connecting end 15. To ensure contact between the contact 8 and the braid 3, the sheath 10 is slid on the wire until the connection

  between the contact probe 8 and the braid 3.

  A suitable locking device can be

  applied to hold sheath 10 in place,

  represented in the drawing o the second contact 8

  has a notch 16 and o the sheath 10 has a complete recess

  Preferably, the outer sheath 10 is elongated to provide a deformation relief for the connection, to ensure that the connection remains intact.

solid when bending the cable.

  To connect the sleeve 9 to the connector 8 and the insulator 7, the part is simply pushed onto the contact 8 and the projection 13 engages the relief II

  and is held in place by the two reliefs II and 12.

  In use, the relief 12 acts as a spring for

  apply the connector against its vis-à-vis in order to

  to establish an intimate contact between the respective contacts.

  With this mode of construction, the connector is cheaper to produce than existing connectors

  and it is much more easily and quickly

  corded to the coaxial cable as existing connectors.

  The coaxial cable connector may be different

  from that described in this application

  patent as a preferred embodiment.

  The insulating profile 7 and the second contact 8 can

  both be manufactured in separate parts

  for example in two separate halves to be assembled together

  ble, with the second contact 8 having its end of

  guiding 14 of any shape allowing for

  be under the braid or on the braid and under the insulating layer 2 of the wire. In addition, the sheath 10 can be replaced by a coupling nut which is screwed onto a

  threaded section on the sleeve 9 with an insulating layer

  lante covering the second contact 8. The shape of the nut is such that it forces the second isolated contact to

connect to the braid 3.

  Similarly, the sleeve 9 can be modified manually.

  that there be an independent spring acting in

  jointing with a threaded nut which forms part of the sleeve 9 and is connected to the insulator 7 and the second

  1.5 contact 8 thus acting in conjunction with the protuberances

11 and 12.

  According to another embodiment, the central contact can be welded to the central wire 5 and can have either in its weld form, or in its form of

  connection ,, any desirable configuration.

  It is obvious to a specialist that changes

  may be made to the connector

  described without departing from the scope of this

vention.
