Abstract

Coaxial cable (1) with a connector which comprises a central contact (23) connected to the central conductor (3) and a sheath contact (11) connected to the conducting sheath (7). An end portion of the conducting sheath is axially flattened to form a disk and is clamped between a transverse wall (15) of the sheath contact (11), which wall is provided at the center with a passage (17), and a sleeve (19) which is bent inwards at its edge and is arranged coaxially with the transverse wall. As a result, the operation of mounting the connector can be mechanized very simply and readily.

Claims

1. A coaxial cable having a connector permanently attached at one end, comprising

a central cable conductor defining a cable axis,

an intermediate insulating layer surrounding said conductor,

a conducting cable sheath having an end portion of the sheath formed by axial compression into a transverse disk,

a sheath contact electrically connected to said sheath end portion, and

a central contact electrically connected to said central conductor,

characterized in that said sheath contact consists of a one-piece unitary article comprising a transverse wall having at least one substantially planar surface, a coaxial sleeve extending in a first direction from said substantially planar surface and having an edge portion remote from said surface, and a socket portion extending coaxially in the direction opposite said first direction,

said transverse wall extends upwardly from an inner peripheral surface of said socket portion and forms a common wall between the socket portion and the coaxial sleeve,

said transverse wall has a passage therethrough, at least said central conductor passing through said passage,

said transverse disk extends parallel to said substantially planar surface, interiorly of said sleeve, and

said sleeve edge portion is bent inwards to clamp said disc against said surface so as to establish electrical and mechanical connection between the conducting sheath and the sheath contact.

2. A cable as claimed in claim 1, characterized by comprising a body of synthetic resin material molded directly around and surrounding said sleeve and a portion of said socket portion.

3. A cable as claimed in claim 1, characterized in that said passage has a diameter at least equal to the outside diameter of said intermediate insulating layer, and in that said layer extends at least into said passage.

4. A cable as claimed in claim 3, characterized by comprising a body of synthetic resin material molded directly around and surrounding said sleeve and a portion of said socket portion.

5. A coaxial cable having a connector permanently attached at one end, comprising

a central cable conductor defining a cable axis,

an intermediate insulating layer surrounding said conductor,

a conducting cable sheath having an end portion of the sheath formed by axial compression into a transverse disk,

a sheath contact electrically connected to said sheath end portion, and

a central contact electrically connected to said central conductor,

characterized in that said sheath contact consists of a unitary article comprising a transverse wall having at least one substantially planar surface, a coaxial sleeve extending in a first direction from said substantially planar surface and having an edge portion remote from said surface, and a socket portion extending coaxially in the direction opposite said first direction,

said transverse wall has a passage therethrough, having a diameter at least equal to the outside diameter of said intermediate insulating layer but less than the outside diameter of said conducting sheath, said intermediate insulating layer extending at least into said passage, and said central conductor passing through said passage,

said transverse disk abuts said substantially planar surface, interiorly of said sleeve, and

said sleeve edge portion is bent inwards to clamp said disc directly against said substantially planar surface, thereby establishing permanent electrical and mechanical connection between the disk and the sheath contact on both sides of the disk.

6. A cable as claimed in claim 5, characterized by comprising a body of synthetic resin material molded directly around and surrounding said sleeve and a portion of said socket portion.
