Abstract
Abstract Illustrated and described is an arrangement for leading a cable into a housing, preferably a cylindrical housing, for electrical or electronic devices. The housing is provided with a cylindrical housing part made detachably for connection of the connection cable. The housing part is divided into two parts, the lead-in sleeve 4 and a cap 3 covering the electrical connection elements. The cap 3 is connected by means of a connection part 10 to the housing 2 in the interior of which the electronic components are accommodated. The cap 3 is supported by axial portions of the connection part 10 and withdrawable from the latter in axial direction. The arresting is done by means of a spring element 21 which engages into a groove 22 of the connection part 10. Further grooves 26 which are arranged at the periphery of the inner wall 19 of the cap 3 and into which a right parallelepipedic protrusion 27 engages prevent turning of the cap 3 with respect to the housing 2. The lead-in sleeve 4 is mounted for infinitely variable rotation in the rear wall of the cap 3. Thus, the connection cable can be introduced into the device in accordance with the requirements at the place of use in any angular position, from an axial position to a position angled at 90° to the longitudinal direction of the electrical device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
Arrangement for leading a cable into a housing which comprises a first housing part accommodating electrical components and carrying an axially extending connection part having connection elements for the cable conductors, a cap-like second housing part enclosing said connection elements, and a third housing part attached to said second housing part for introduction of said cable into said second housing part, in which arrangement said cap-like second housing part encloses said axially extending connection part in a sliding fit and comprises a detent engaging a circumferential groove in said connection part whereby said cap-like second housing part is held against axial displacement but can be detected by axial withdrawal from said connection part upon disengagement of said detent, and in which arrangement said cap-like second housing part comprises at its inner face at least one axial groove and said connection part comprises at least one protrusion which engages into said axial groove, whereby said cap-like second housing part is fixed on said connection part in a predetermined angular position.
Claim 2
Dependent Claim
169 words
Arrangement for leading a cable into a housing which comprises a first housing part accommodating electrical components and carrying an axially extending connection part having connection elements for the cable conductors, a cap-like second housing part enclosing said connection elements, and a third housing part attached to said second housing part for introduction of said cable into said second housing part, in which arrangement said cap-like second housing part encloses said axially extending connection part in a sliding fit and comprises a detent engaging a circumferential groove in said connection part whereby said cap-like second housing part is held against axial displacement but can be detected by axial withdrawal from said connection part upon disengagement of said detent, and in which arrangement said cap-like second housing part comprises at its inner face at least one axial groove and said connection part comprises at least one protrusion which engages into said axial groove, whereby said cap-like second housing part is fixed on said connection part in a predetermined angular position.
Claim 3
Dependent Claim
61 words
Arrangement according to claim 1 in which said cap-like second housing comprises at its inner face a plurality of axial grooves and said at least one protrusion of said connection part selectively engages one of said axial grooves whereby said gap-like second housing part is fixed on said connection part in a selected one of a plurality of predetermined angular positions.
Claim 4
Dependent Claim
23 words
Arrangement according to claim 1 in which said connection part comprises axially spaced cylindrical portions on which said cap-like second housing part bears.
Claim 5
Dependent Claim
22 words
Arrangement according to claim 1 in which a resilient sealing ring is disposed between said second housing part and said connection part.
Claim 6
Dependent Claim
41 words
Arrangement according to claim 1 in which the inner faces of said cap-like second housing part and an end face of said connection part define within said second housing part a connection space permitting the electrical connections of the cable conductors.
Claim 7
Dependent Claim
24 words
Arrangement according to claim 5 in which the connection part comprises at its end face protrusions accommodating the connection elements for the cable conductors.
Claim 8
Dependent Claim
23 words
Arrangement according to claim 1 in which a resilient sealing ring is disposed between said connection part and said cap-like second housing part.
Claim 9
Dependent Claim
46 words
Arrangement according to claim 1 in which said cap-like second housing part has an annular cylindrical opening and said third housing part has an annular cylindrical collar rotatably received in said annular cylindrical opening, said opening and said collar having mutually matching portions of different diameters.
Claim 10
Dependent Claim
42 words
Arrangement according to claim 8 in which said annular cylindrical opening and said annular cylindrical collar comprise matching opposite grooves in which a spring ring is disposed for rotatably holding said third housing part in the opening of said second housing part.
