The invention relates to a multi-pole plug insert, for example for being fitted in a plug housing comprising a through-aperture for accommodating the plug insert and a flange face for fixing the plug housing to a base plate or to the wall of a switch cabinet, or for being directly attached to holding devices or walls of switch cabinets or the like.
In an advantageous embodiment thereof, the first connecting face of the first part provided with the apertures for the plug-in contacts forms an angle with the second connecting faces provided with the connecting apertures for the connecting contacts, and it is possible for the first connecting face on the one hand and the second connecting faces on the other hand, together, to form an angle of 90°, with the connecting faces being co-planar relative to one another or that the first connecting face on the one hand and the second connecting faces on the other hand, together, form an angle ranging between 90° and 180°.
FIGS. 13a and 13b show a cross-section through a conventional attachable housing 101a and 101b respectively and a plug insert 102 in accordance with the invention inserted into said housings. The plug insert 102 comprises screwed-on fixing clips 126 resting on bases 138a and 139b respectively in the housing 101 and are connected thereto by screws 127. The bases 138a according to FIG. 13a are positioned towards the front towards the plug end in the housing 101a, with the fixing clips 126 for fitting and screwing on the plug insert 102 being positioned thereon towards the rear. The bases 139b according to FIG. 13b are set back from the plug end and moved further into the housing 101b. In this case, the plug insert 102 may be fitted and screwed on from the front end. The plug insert 102 comprises a first part 104 inserted into the through-aperture 103 of the attachable housing 101, and a second part 105 positioned outside same and fitting into the open cross-section of the attachable housing 101. The first part 104 passes into a base plate 106 of the second part 105 so as to be integral therewith. The base plate 106 comprises a lateral frame part 107 into which there is fitted a cover part 114. The first part 104 is provided with pairs of apertures (not illustrated) which contain contact bushes which are in contact with conductor rails 111 which are divided into first contact tongues 112 and second contact tongues 112', with only one half of the second part having a reference number. The conductor rails 111 are held between the base plate 106 and the cover part 114. These parts may be clamped together. The parts mentioned so far are arranged symmetrically relative to a central plane E of the second part 105. The cover part 114 inserted into the frame part 107 of the second part is provided with multiple apertures and produced in one piece. It holds four units of connecting contacts each consisting of a holding plate 115, 115', a clamping screw 116, 116' threaded into said plate, and a movable clamping clip 117, 117'. When tightening the clamping screw 116, 116', the clamping clip 117, 117' comes to rest against one of the contact tongues 112, 112' so that a conductor may be clamped into this region. To permit the clamping screws to be adjusted, the cover part 114 is provided with screw apertures 118, 118', with further plug-in apertures 119, 119' being provided for plugging in conductor wires. The type of plug insert 102 illustrated here comprises a first connecting face 113 with apertures for the contact inserts, and two connecting face parts 122, 123 which form an angle of 90° relative to said first contact face and which are co-planar and symmetric relative to one another, with plug-in apertures 119 for connecting contacts. Plug inserts of this type may, optionally, be slid through an attachable housing in their entirety by being tilted laterally.
In FIG. 16, the plug insert 152 is inserted into a conventional attachable housing 151. The plug insert 152 comprises screwed-on fixing flanges 176 which rest on bases 188 in the attachable housing 151 and are connected thereto by screws 177. In this case, the bases 188 do not comprise threaded holes, but through-holes, whereas the screwed-on fixing flanges 176 consist of a reinforced material and comprise threaded holes so that the threading process can take place from the plugging-in end. The plug insert 152 comprises a first part 154 inserted into the through-aperture 153 of the attachable housing 151, and a second part 155 positioned outside the attachable housing 151 and not projecting beyond the open cross-section of same. The first part 154 passes into the second part 155 so as to be integral therewith. The plug insert 152 is provided with longitudinal recesses accommodating conductor rails 161. Plug-in contacts (not illustrated) are slid on to said conductor rails and crimped on for example. The conductor rails 161 pass into the connecting contacts 167, 167' so as to be integral therewith. Furthermore, they comprise central contact tongues 183. The conductor rails 161 are punched out of plate metal material. The connecting contacts 167, 167' end in open plug-in aperture 169, 169'. The contact tongues 183 are positioned in the region of the plug-in apertures 171 provided for contact bridges to be illustrated at a later stage. The plug insert 152 comprises longitudinal bores 198 which are provided for passing through screws or rivets 199 for connecting a plurality of disc-shaped parts of the plug insert.
