Definitions

  • the invention relates to a lockable electrical connector according to the preamble of claim 1.
  • DE-A-31 50 424 shows such an electrical connector with a U-shaped wire spring which locks the connector with the mating connector.
  • the locking spring can be expanded by sliding it onto two housing slopes so that the locking is released.
  • Such a mechanism is susceptible to tilting of the wire spring, especially in the case of very wide, multi-pole connectors. Tilting, however, leads to an uneven spreading of the spring.
  • the connector housing must always be accessible on its two broad sides for detaching.
  • the invention has for its object to improve the handling of the connector when releasing the connection.
  • the invention leads to a securely lockable connector that - even with considerable Pollution - is easy to solve.
  • This is the direct consequence of dispensing with the known sliding arrangement and also enables the safe and easily releasable locking of multipole and in particular wide connectors.
  • the connector according to the invention only the two narrow sides of the connector housing need to be accessible for detachment, a finger width being sufficient; the connector can thus be arranged with one or even both broad sides in the immediate vicinity of a wall or the like, without this arrangement hindering the detachment.
  • dispensing with a sliding movement of the spring there is no risk of grinding away any corrosion protection of the metal spring.
  • FIG. 1 shows a perspective illustration of an electrical two-pole connector which is intended to be pushed onto a mating housing, the locking spring to be pushed on being shown again for the sake of clarity.
  • Figure 2 shows the top view A of the connector of Figure 1.
  • FIG. 3 shows view B of the connector according to FIG. 2.
  • a connector 1 is shown, which is to be locked with a mating connector 2.
  • the connector 1 comprises a flat housing 3 with two contact chambers 4, into which electrical plug contacts, not shown, such as sockets, flat plugs and the like can be used. These plug contacts are usually connected to electrical lines which emerge from the rear section 5 from the housing 3, optionally sealed.
  • the housing 3 can be provided in the interior 6, in particular at the transition to section 5, which cannot be seen in FIG. 1, as is known from the prior art mentioned.
  • the interior 6 of the housing 3 is intended for receiving the mating connector 2, which is provided with corresponding electrical contacts.
  • latching 2 locking lugs 7 are arranged on the narrow sides of the mating connector 7 with bevels 7a, which can be inserted into corresponding slots 8 of the housing 3.
  • a U-shaped locking spring 9 made of wire is provided for sliding onto the housing 3, see FIG. 1 at the top right.
  • the locking spring 9 and the housing 3 are constructed symmetrically, so that the same parts or sections with the are provided with the same reference number. For better clarity, the locking spring is shown in FIG. 1 once before it is mounted and once after it is mounted on the housing 3.
  • the locking spring 9 initially consists of a central base section 10 which is U-shaped, see FIG. 2.
  • the base section 10 consists of a web 11 and two legs 11a extending in the plugging direction X - X.
  • the base section 10 extends in a plane which extends in the plug-in direction X - X; the web 11 is slightly bent in this plane, compare FIGS. 2 and 3.
  • the locking spring 9 further consists of two spring legs 12, which are bent vertically from the legs 11a and extend downwards with a slight approximation to one another and form locking sections 13.
  • the spring legs 12 then move away from each other into a two-armed lever 14.
  • the two-armed levers 14 are bent almost at right angles from the spring legs 12 to the rear.
  • the first lever arms 15 run approximately parallel to the legs 11a, compare FIGS. 2 and 3, followed by second lever arms 16 slightly angled outwards at the point of inflection P.
  • the second lever arms 16 form handles, in particular the thumb and can easily grip the index finger of one hand to release the locking and plug connection.
  • every second lever arm 16 is U-shaped by itself, in that the section 17 adjoining the first lever arm 15 is bent twice approximately at right angles, compare FIG. 3.
  • the lever arms 16 end with the wire ends 18, approximately above the break point P. Mit 18a, the end of the lever arm 16 at the break point P is designated.
  • the locking spring 9 is pushed onto the housing 3 from above, see FIG. 1 in the middle.
  • the middle base section 10 is located on the upper side 19 of the housing 3, that is to say in a plane which extends in the plug-in direction X-X.
  • the legs 11a extending in the X-X direction have slid on the housing 3 when slid over slopes 20 and are locked behind projections 21.
  • the two bent spring legs 12 extend through slots 22 into the grooves 8 in the interior 6 of the housing 3, where they form locking sections 13.
  • the spring legs 12 emerge again from the housing 3 below the slots 8 and then pass into the first lever arms 15, which run approximately in the plug-in direction X-X.
  • the angled second lever arms 16 connect to the first lever arms 15.
  • the point P of the bend forms the support for the two-armed lever 14 on the outside 23 of the housing 3.
  • the second lever arms 16 are supported via the wire ends 18 above the vertex P on the outside 23 of the housing 3 and thus form a second bearing for everyone two-armed lever arm 14. This largely prevents transverse twisting or twisting of the handling section, that is to say the second lever arm 16.
  • the second lever arms 16 are pressed against the housing 3 by means of the thumb and forefinger of one hand.
  • the locking spring 9 tilts about the inflection points P, whereby the spring legs 12 are spread.
  • the first lever arms 15 pull the locking sections 13 out of the grooves 8.
  • the catches 7 of the mating connector 2 are released so that the plug connection can be released by pulling the two connectors 1 and 2 apart.
  • the spring legs 12 are forcibly spread by the run-up bevels 7a of the latching lugs 7 until after the insertion of the mating connector 2, the locking sections 13 lock behind the latching lugs 7 and secure the locking in a form-fitting manner.
