DETAILED DESCRIPTION
[0142] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
[0143] FIG. 1 shows a first embodiment of a plug screw connection system 100 in an exploded view. A socket 20 and a plug 30 can be seen. The plug 30 has a first inner contact carrier 5 and a first outer contact carrier 3. The first outer contact carrier 3 has an O-ring 4. A nipple 1 has an O-ring 2. The first inner contact carrier 5, the first outer contact carrier 3, the nipple 1 and the sealing means, i.e. the O-rings 4 and 2, form a socket into which a cable not shown can be received or assembled from the receiving side 31.
[0144] FIG. 1 further shows a socket 20 with a second outer contact carrier 6 and a second inner contact carrier 7. The inner contact carrier 7 with a threaded receptacle 71 can be screwed to a pressure sleeve 8. The pressure sleeve 8 has a pressure element 81 one-piece connected thereto. A pressure screw 10 is designed in such a way that it can be screwed onto the nipple 1 and, in particular, presses the pressure element 81 of the socket in such a way that a cable not shown, which is guided from the receiving side 21 of the socket 20 into the socket or is assembled on it, can be pressed. A sealing ring 9, which interacts with the pressure screw 10, can seal the pressure screw 10 against a connection geometry not shown.
[0145] FIG. 2 shows a top view of the receiving side 31 of the plug 30 of the plug screw connection system 100. The pressure screw 10, which at least partially encases the plug 30, can be seen. The inner contact carrier 5 has contact pins 51.
[0146] FIG. 3 shows a side view of the plug screw connection system 100 of FIG. 1. The nipple 1 of the plug 30, the pressure screw 10 of the socket 20 can be seen.
[0147] FIG. 4 shows a sectional view A-A from FIG. 3. The assembly of the plug 30 with nipple 1, first inner contact carrier 5, first outer contact carrier 3, and a contact pin 51 can be seen. Furthermore, the socket 20 comprises a second outer contact carrier 6, a second inner contact carrier 7, and a contact socket 61. The socket 20 is held on the nipple of the plug 30 by means of the pressure screw 10 and in particular sealed.
[0148] FIG. 5 shows a view of the plugged plug screw connection system from FIG. 1. The pressure screw 10, the nipple 1, the first inner contact carrier 5 and the first outer contact carrier 3 can be seen.
[0149] FIG. 6 shows a second embodiment of the plug screw connection system in an exploded view. The socket 20 and the plug 30 can be seen. The plug 30 comprises a first inner contact carrier 5, a first outer contact carrier 3, an O-ring 4 on the first outer contact carrier 3, a nipple 1 with a connection thread 11, with which the nipple 1 can be screwed into a connection geometry not shown, for example. The socket 20 has a second inner contact carrier 7, which includes recesses 72 that facilitate assembly. Furthermore, the socket 20 has a second outer contact carrier 6. The pressure element 81 is formed separately from the pressure sleeve 8. Furthermore, the plug screw connection system 100 comprises a pressure screw 10 with a sealing ring 9.
[0150] It is understood that, as described in the general description section, the pressure sleeve 8 one-piece connected to the pressure element 81 can also be combined with the inner contact carrier 7 and have recesses 72.
[0151] FIG. 7 shows a side view of the plug screw connection system 100 of FIG. 6.
[0152] FIG. 8 shows a sectional view A-A of FIG. 7. It can be seen that the pressure screw 10 has an inner thread 101 which interacts with an outer thread 12 of the nipple 1. Furthermore, it can be seen that, by screwing the pressure screw 10 onto the nipple 1, the pressure element 81 is pressed against the pressure sleeve 8, whereby an inner diameter D of the pressure element 81 is reduced and the latter can enter into a non-positive connection with a cable that is not shown.
[0153] FIG. 9 shows a view of the plugged plug screw connection system 100 of FIG. 6.
[0154] FIG. 10 shows a plug screw connection system with a socket 20 separated from a plug 30.
[0155] FIG. 11 shows a sectional view A-A from FIG. 10. The socket 20 with the nipple 1, the first inner contact carrier 5, the first outer contact carrier 3, and the contact pin 51 can be seen. The socket 20 comprises a second outer contact carrier 6, a second inner contact carrier 7, and the contact socket 61. The socket 20 is held on the nipple of the plug 30 by means of the pressure screw 10 and is sealed in particular.
[0156] FIG. 12 shows a view of the plug screw connection system 100 of FIG. 10.
[0157] FIG. 13 shows a plug screw connection system 100 with a nipple 1 and a pressure screw 10 in an assembled state. The nipple 1 comprises an outer contact carrier 3.
[0158] FIG. 14 shows the plug screw connection system 100 from FIG. 13, in which the outer contact carrier 6 of the socket 20 shown in FIG. 15 is separated from the nipple 1.
[0159] FIG. 15 shows the plug screw connection system from FIG. 13 in a longitudinal section. The plug 30 comprises a nipple 1 with an outer contact carrier 3 and an inner contact carrier 5. An O-ring 4 is applied to the nipple 1. The plug 30 is inserted into the socket 20. The socket 20 comprises an outer contact carrier 6 and an inner contact carrier 7. Furthermore, the socket comprises a pressure sleeve 8 and a pressure element 81 resting thereon. The screwed-on pressure screw 10 acts on the pressure element 81.
[0160] FIG. 16 shows an embodiment of the plug screw connection system 100 with an angle connector 90.
[0161] FIG. 17 shows the plug screw connection system 100 in a sectional view. The nipple 1 is screwed into an inner thread 92 of the angle connector 90. Furthermore, the pressure screw 10 is screwed onto the nipple 1.
[0162] FIG. 18 shows the plug screw connection system 100 of FIG. 16 comprising the angle connect-or 90, the plug 30 and the socket 20 in an exploded view.
[0163] FIG. 19 shows the plug screw connection system 100 of FIG. 18 in a sectional view comprising the angle connector 90, the plug 30 and the socket 20.
[0164] FIG. 20 shows another embodiment of a plug screw connection system 100 as a flying connection.
[0165] FIG. 21 shows an exploded view of the plug screw connection system 100 from FIG. 20 comprising a first pressure screw 10.1 and a second pressure screw 10.2. The first pressure screw is screwed onto the nipple 1 on one side. On the opposite side, the second pressure screw 10.2 is screwed onto a connecting piece 98 of the nipple 1.
[0166] FIG. 22 shows a sectional view of the plug screw connection system 100 from FIG. 21 comprising a first pressure screw 10.1 and a second pressure screw 10.2.

[0167] FIG. 23 shows a detailed exploded view of the plug screw connection system 100 from FIG. 20. The first pressure screw 10.1 is screwed onto the nipple 1. An O-ring 9.1 seals between the pressure screw 10.1 and the connecting piece 98. The first pressure screw 10.1 acts on a first pressure element 81.1, which in turn interacts with a first pressure sleeve 8.1. The pressure sleeve 8.1 engages over an inner contact carrier 7 with wire-receiving openings 72, a channel 73 between an outer surface 74 and a wire-receiving opening 72 and a cover sur-face 76. The inner contact carrier 7 is arranged in the outer contact carrier 6.
[0168] The second pressure screw 10.2 can be screwed onto a connecting piece 98, which can be fitted onto the nipple 1. An O-ring 9.1 seals between the second pressure screw 10.2 and the connecting piece 98. The second pressure screw 10.2 acts on a second pressure element 81.2, which in turn interacts with a second pressure sleeve 8.2, which is supported against the connecting element 98. An inner contact carrier 5 and an outer contact carrier 3 are arranged in the nipple 1.
