No. 5,591,042 comprises two plug-in parts, i.e. one plug and one Mating connector that is used to produce a perfect electrical Connection both completely pushed into each other and are releasably locked together, a spring element 6 (There Figures 1A to 1D) is provided, which between the both plug-in parts works and which one in the event of a faultless electrical connection the mating connector from the Ejects plug.
  • the known connectors work according to the so-called "go / no-go" principle, i.e. that if the connector is not is completely locked, by means of the spring force of a spring element the two plug-in parts pushed apart again or the mating connector is ejected from the connector.
  • a spring-link arrangement for the management of the above Spring element provided, these Spring-link arrangement causes a non-linear spring characteristic.
  • the spring force is preferably at the beginning of the insertion process (Mating connector in connector) stronger than to a later one Time just before the end of the insertion.
  • a spring characteristic is shown as an example, that reflects this fact.
  • the spring force is relatively high, so that in the event of a termination of the insertion into one another, the two plug parts be pushed apart again.
  • FIGS. 1 and 2 The first embodiment is shown in FIGS. 1 and 2. With 1 the plug is designated, while with the reference symbol 2 the mating connector is designated.
  • the mating connector 2 is inserted into the opening on connector 1 until a driver 2a, for example in the form of a paragraph, with a Spring element 3 comes into contact.
  • the spring element 3 is in Connection with Figure 3 will be described in detail.
  • FIG. 1 (b) A state is shown in FIG. 1 (b), in which the mating connector 2 is about 2/3 in the connector 1 is inserted. If the mating connector 2 is now released, so presses the spring element 3 under tension the mating connector 2 out of connector 1 again. Will the mating connector 2, on the other hand, is inserted further, so that a bridge part 3d of the spring element 3 by means of a deflection device 5 the connector 1 deflected down and can along the Relax underside of driver 2a.
  • the driver 2a causes the pull-out Spring is pressed down and a spring force builds up, which counteracts the removal of the mating connector 2. Becomes overcome this force, the mating connector 2 is due to the Acceleration pulled out of connector 1. The peeling process interrupted, the mating connector slips due to the spring force (inclined contact surface of the holding section 6 and of paragraph 2b) back into plug 1.
  • FIG. 2 (a) shows the state according to FIG. 1 (d), it can be seen that the spring element 3 with its bridge part 3d lies in front of the mating connector 2.
  • FIG. 2 (b) shows the state in which a Disconnect the connector.
  • the bridge part 3d the spring element 3 is by hand in the middle push down to bridge part 3d around paragraph 2b to lead around.
  • paragraph 2b of the mating connector 2 is not the mating connector can encompass more of the spring element 3 2 are pulled out of plug 1.
  • the spring element 3 used in this first embodiment is essentially U-shaped and schematic in Figure 3 shown. This spring element 3 is in the connector 1 after the figure 1 arranged so that the bridge part 3d in Cross section can be seen, which is preferably circular is.
  • the spring-backdrop arrangement according to the invention consisting of the spring element 3 and a backdrop 4, is in Figures 3 (a) and 3 (b) shown in two states, wherein in Figure 3 (a) relaxed spring element 3 is shown while in the figure 3 (b) a spring element 3 deformed under the action of force F. is shown.
  • the spring element 3 has at the end of two legs 3a and 3b are arranged on both sides of the bridge part 3d, end regions 3c on that bent almost L-shaped upwards (in Figure 3) are. Due to the rounding in the end region 3c of the spring element 3, which rests there against the backdrop 4 becomes a uniform one Ensured along the backdrop 4.
  • the backdrop 4 has in this embodiment on both sides two guide surfaces 4a and 4b, which are at an angle to each other run, which is shown by way of example at about 30 °, and these two guide surfaces 4a and 4b go at a kink K into each other.
  • a degressive spring characteristic FK of the spring element 3 results, as is shown schematically or idealized in the following diagram: If the end regions 3c of the spring element 3 are in the region of the guide surfaces 4a, the spring characteristic FK is in the region 0A, ie in the region of the steeper line, while if the end regions 3c are in the region of the guide surfaces 4b, the spring characteristic FK is then in the region AB lies.
  • the spring-link arrangement according to the invention is intended at the beginning of the compression of the spring Spring force rise sharply to a level at which the Spring force is large enough, the mating connector 2 from the connector 1 push out. Because this spring force is the actual mating process counteracts and thus complicates the plugging, the Spring force no longer increase as much in the further course, since in the further course of the plugging the friction between the electrical contacts must also be overcome. Consequently can insert the required force for full insertion the plug-in parts are kept relatively low overall.
  • FIG. 4 shows the second embodiment of the invention Plug connection shown. Same or equivalent Components have the same reference numerals as for the characterized in the first embodiment.
  • the spring link arrangement 3, 4 is located in the connector 11 left in the housing, the mating connector 12 in this second Embodiment has a lever 14 which at the beginning of the insertion is pressed down (can be seen in FIG. 4 (b)) and which has an opening 14b at its distal end 14a, which engages with the spring 13.
  • the opening 14b with the spring 13 is engaged and the end 14a under the housing part 11a "Plunges"
  • the mating connector 12 can be inserted into the connector 11 be, against the spring force of the spring 13, analog the first embodiment.
  • the lever 14 can be pressed down manually, or, as shown in FIG. 4, preferably automatically be done by providing two bevels, one at the distal end 14a of the lever 14 and the other at the end of the Housing part 11a, these two bevels lying opposite one another and when inserting the mating connector 12 in the Slide connector 11 past each other.
  • the backdrop 4 is also in accordance with this second embodiment 3 executed and not shown in Figure 4.
  • the substantially U-shaped spring 13 is in the Connector 1 also arranged horizontally and in cross section preferably round.
  • the spring 13 is in this embodiment, in contrast the first embodiment, under tension, is supported however only in the housing of the plug 11 and loaded the mating connector 12 is not. So that is the electrical Connection without spring load 13.
  • the mating connector 12 is removed by the lever 14 is pressed down on the actuator 14d until the Undercut 14c disengages from protrusion 11b arrives so that the spring force of the spring 13 the mating connector 12th pushes out of the connector 11.
  • the spring characteristic FK is adaptable and according to the first Embodiment is adjustable.
  • the plug 21 is essentially a T-shaped recess 21a into which the lever 14 engages.
  • the mating connector 22 is in this third embodiment Can only be inserted into the plug 21 when the lever is actuated 24 is pushed up to the catch 25 (see Figure 5 (a)) and the lever 14 is pressed down, as shown in Figure 5 (b). Otherwise it works Latch 25 as a plug-in inhibitor.
  • the distal end 14a of the lever 14 enters with the spring 23 Intervention and the further insertion or insertion of the Mating connector 22, the spring 23 is deformed. This will make the Desired ejection force built up in the spring 23, as in the previous embodiments.
