Definitions

  • the invention relates to an electrical connector consisting of a base part for installation in a housing wall and a connector part with a test adapter arranged thereon at the rear, which has screw angles for screwing to contact shoulders in the base part, and with latching elements on the base and connector part, which occur when the connector part is inserted from the inside facing away from the plug side, snap into the base part in the sense of pre-fixing the connector part on the base part, and furthermore with protective contact angles provided on the narrow sides of the connector part.
  • Known electrical connectors of this type enable the preferred introduction of the connector part together with the test adapter into the base part from the inside, previously mounted on the outside of a wall in a housing, for example a control cabinet, and only by one individual person, since it is possible for the fitter to move from the inside due to the pre-fixation by the locking elements, after pre-fixation, for example, to go around the cabinet to the outside and then finally screw the connector part and the base part firmly together .
  • the latching elements are formed, on the one hand, by wedge knobs provided on the two longitudinal inner walls of the base part and, on the other hand, by ribs arranged on the longitudinal sides of the connector part, which are snap-fitted when inserted from the inside over the wedge knobs.
  • an electrical plug connection consisting of a coupling and a plug part
  • the coupling part is assigned strut hooks with which the coupling part, when it is plugged into the plug part, additionally through a built-in wall Locking can be secured mechanically, the plug part in turn being attached to this installation wall.
  • the present invention has for its object to provide an electrical connector of the generic type, in which the connector part can be easily disengaged from its prefixed position in the base part with little construction effort if necessary and without the use of tools.
  • the latching elements for the pre-fixation are formed by strut snap hooks arranged on each of the two narrow sides of the connector part and counter-latching pieces correspondingly provided on the base part, and the strut snap hooks are formed in one piece with mounting webs which are fastened to the protective contact angles.
  • Such strut locking hooks form an easy-to-operate elastic system. If necessary, it is sufficient to press the spring strut hooks by hand in the sense of their unlocking in order to free the hooks from the counter-locking piece. Due to their arrangement on the two narrow sides of the connector part, the suspension strut locking hooks are also extremely easy to reach overall and can therefore also serve as a whole for handling the connector part with an arranged test adapter. Since the existing lateral protective contact angles of the connector part are used to fasten the strut locking hooks with the aid of the mounting webs which are arranged thereon in one piece, a very simple construction is also achieved. In this case, clips are also expedient on the mounting webs integrally formed, with which the mounting webs can be clipped onto the protective contact angle.
  • the electrical connector has a base part 1, which is fastened on the outer wall of a housing, for example a control cabinet, in the region of an opening through the wall, for which purpose it is provided with screw flanges 1a.
  • the electrical connector further includes a connector part 2 with a test adapter 2a arranged thereon at the rear. As illustrated in FIG. 1, the connector part 2 with the test adapter 2a is inserted into the base part and fastened to the base part from the rear, ie from the inside facing away from the plug side.
  • screw angles 3 are provided on the connector part 2, which can be screwed onto the shoulders 5 in the base part 1 by means of screws 4.
  • a snap-in connection is provided for a pre-fixation between the base part 1 and the connector part 2, which enables the person after inserting the connector part 2 into the base part 1 from the rear or inside to go to the front of the housing wall, for example of a control cabinet, in order to carry out the final screwing there.
  • spring strut snap hooks 6 are now provided as a set of elements of the cooperating snap elements on the connector part 2 on its two narrow sides, for which counter locking pieces 7 are provided in the corresponding narrow sides of the inner wall area of the base part 1 are which are snapped behind by the hook sections at the lower free end of the strut locking hook 6 in the sense of pre-fixing.
  • the suspension strut hooks 6 can be easily and conveniently pressed together by hand when needed, i.e. H. to move towards the connector part 2, whereby the locking connection is released. Since the strut locking hooks are particularly easy to reach due to their position on the two narrow sides of the connector part, they can also be used as a whole for handling the connector part. They are expediently provided on the outside with an ergonomically shaped recessed grip 8, which can be corrugated in the base in the sense of a secure grip.
  • the protective contact angles 9 present on the narrow sides of the connector part 2 are used for the attachment and fixing of the strut locking hooks.
  • the strut locking hooks 6 are formed in one piece with mounting webs 10, to which, in turn, sections 11 are integrally formed, which can be snapped onto a section of the protective contact angle 9, as shown in FIG. 3.
  • a stop 12 is formed on the mounting webs 10, pointing outward toward the strut locking hook 8, which serves to protect the strut hook 8 against excessive compression.
