an embodiment of a threaded cable joint shown in fig1 and 2 comprises a connection piece constructed to be electrically conductive , which is given the overall reference 10 and which has a cylindrical attachment 12 with an external thread 14 , with which the connection piece 10 may be screwed into a wall 16 of a housing , for example . moreover , the connection piece comprises a key face section 18 , which is provided with key faces 20 and directly adjoins the cylindrical attachment 12 on a side opposite an end 22 of the cylindrical attachment 12 on the housing side . a cylinder section 24 bearing an external thread 26 is provided on a side of the key face section 18 of the connection piece 10 opposite the cylindrical attachment 12 . a cap nut 28 , given the overall reference 28 , may be screwed with its internal thread 30 onto the external thread 26 . the cylinder section 24 serves to receive a seal support , given the overall reference 32 , which engages into the cylinder section 24 with a holding attachment 34 and is mounted on an inside cylinder face 36 thereof . moreover , the seal support 32 is supported at a flange face 38 on a face side 40 of the cylinder section 24 facing away from the key face section 18 and is thus fixed in the direction of a longitudinal axis of the threaded cable joint according to the invention against displacement in the direction of the key face section 18 . the seal support 32 further comprises a leaf segment cage 44 , which itself encloses a seal 46 , in which case the seal 46 may , moreover , be fixed by an inside attachment 48 against a displacement in the direction of the longitudinal axis 42 towards the key face section 18 . the leaf segment cage 44 may itself be acted upon by a sloping face 50 of the cap nut 28 , which when the cap nut 28 is increasingly tightened onto the external thread 26 , deforms the leaf segments of the leaf segment cage 44 increasingly in the direction of the longitudinal axis 42 , and thus also moves the seal 46 receiving the leaf segment cage 44 so far in the direction of the longitudinal axis 42 that an inside passage 52 may be abutted against an outer cable sheath surface 54 of a cable 56 with pressure to form a seal . the cable 56 in this case runs through an opening 58 of the cap nut 28 coaxial to the longitudinal axis 42 , then through the passage 52 of the seal 46 , and then passes through an inside opening 60 of the seal support 32 . adjoining the seal support 32 , the cable 56 extends through an interior portion 62 of the connection piece 10 , which expands from the cylinder section 24 through the key face section 18 and the cylindrical attachment 12 as far as an opening 64 of the connection piece on the housing side . an insert part , given the overall reference 66 , extends in the interior 62 from the opening 64 on the housing side , said insert part having an annular body 68 with a radially external cylindrical face 70 and a flange 72 extending radially outwards over the cylindrical face 70 and abutting against a face 74 of the end 22 of the connection piece 10 on the housing side . the insert part 66 additionally has fingers 76 extending from the inside body 68 and extending in the direction of the longitudinal axis 42 , said fingers engaging with a detent 78 standing radially outwards in relation to the longitudinal axis 42 into a groove 80 in the connection piece 10 which preferably lies in the region of the key face section 18 and extends radially outwards from the inside cylinder face 36 . the insert part 66 may thus be inserted from the end 22 on the housing side into the interior 62 of the connection piece 10 , in which case the fingers 76 may be elastically bent in the direction of the longitudinal axis 42 so that the detents 78 thereof slide along on the inside cylindrical face 36 from the opening 64 as far as the groove 80 , and then engage into the groove 80 , thus forming a catch connection with this , while at the same time the flange 72 abuts against the end 22 of the connection piece 10 on the housing side . the insert part 66 supports a shield contact element , given the overall reference 90 , which lies on the cylindrical face 70 of the annular body 68 with a support part 92 constructed in the form of an open ring , in which case the support part 92 is a flat : material strip bent into an open ring . for fixture of the support : part 92 on the cylinder face 70 , the support part 92 is held by projections 94 projecting from the flange 72 which engage over the support part 92 on an outside 96 facing away from the cylindrical face 70 , so that the support part is fixed in a slot formed between the projections 94 and the cylindrical face 70 . contact bows 100 located between the fingers 76 extend from the support part 92 , said contact bows having an end 102 facing away from the support part 92 with a v - shaped bend arranged on a first : bow arm 106 . the first bow arm 106 and a second bow arm 108 are connected to one another via a knee - like bend 110 . the second bow arm 108 adjoins a bend 112 in the shape of an inverted v and this lies between a third bow arm 114 extending radially outwards away from the support part 92 in relation to the longitudinal axis 42 and a s second bow arm 108 . each contact bow 100 serves to form an electrical contact between a cable shield 120 , which abuts against an internal conductor region 122 of the cable 56 and encloses this . the term internal conductor region 122 relates to all the sub - components enclosed by the cable shield 120 . for this , the contact bow 100 with the v - shaped bend 104 touches the cable shield 120 at a first contact point 124 . moreover , each contact bow 100 preferably extends in a plane running through the longitudinal axis 42 and is resiliently movable lying in the plane , whereby the bow arms 106 , 108 and 114 remain lying in the plane . in addition , the contact bow 100 touches the connection piece 10 in the region of its inside cylindrical face 36 by means of the bend 112 in the form of an inverted v forming a second contact point 126 . because of the shape of the contact bow 100 the knee - like bend 110 lies between the first contact point 124 and the second contact point 126 with the first bow arm 106 leading away from said bend and the second bow arm 108 , which , in the case of elastic material of the contact arm , performs a spring action , which on the one hand presses the bend 104 against the cable shield 120 and on the other hand presses the bend 112 against the inside cylindrical face 36 of the connection piece 10 , and thus also maintains the electrical contact in the region of the first contact point 124 and the second contact point 126 . because the third bow arm 114 runs radially outwards from the support 92 as far as the bend 112 in the form of an inverted v , a lever arm is also formed between the support part 92 and the bend 112 which permits a resilient movement of the bend 112 in the direction of the inside cylindrical face 36 of the connection piece 10 , so that as a result of the structure of the contact bow 100 made of resilient material , both a contact in the region of the first contact point 124 and a contact in the region of the second contact point 126 are constantly maintained . therefore , with the threaded cable joint according to the invention it is merely necessary to remove an outer cable sheath 130 sufficiently so that the cable shield 120 enclosing the internal conductor area 122 is exposed , but still closely encloses the internal conductor area 122 . if a cable thus partially freed from the outer cable sheath 130 is inserted into the threaded cable joint according to the invention , i . e . so far that the exposed cable shield 120 lies in the region of the interior 62 , then an electrical contact is automatically formed between the cable shield 120 and the connection piece 10 by means of the number of contact bows 100 . in this case , the cable is preferably inserted so far that the area still provided with the outer cable sheath 130 lies in the passage 52 of the seal 46 , so that the seal 46 may be brought into abutment against the outer cable sheath face 54 by tightening the cap nut 28 , and thus the cable 56 is sealed in the threaded cable joint on the one hand and may be fixed non - positively so as to be relieved from tension on the other hand , while at the same time an electrical contact may be formed between the cable shield 120 and the connection piece 10 via the contact bows 100 .
