Definitions

  • the present invention relates to an electrical connector for electrically connecting at least two electrical lines, having the features of the preamble of claim 1.
  • Such a connector is for example from the DE 197 49 130 C1 known and has two plug-in parts containing mutually complementary electrical coupling parts.
  • the first plug-in part comprises a receiving sleeve; which encloses the first coupling part and which has on its inside a locking element in the form of a ring with inwardly projecting spring tabs.
  • the locking element is adjustable between a locking position and an unlocking position and biased due to its spring elasticity in its locking position.
  • On the receiving sleeve a sliding sleeve is slidably mounted, with which the locking element can be moved into its unlocked position.
  • the second plug-in part has a plug-in tube which encloses the second coupling part.
  • the locking element When inserting the plug-in tube into the receiving sleeve, the locking element can be supported in its locking position on the outside of the plug tube, which expediently has an annular groove at this point, whereby the plug-in parts are secured together.
  • This fuse can be solved by that the sliding sleeve is actuated for adjusting the locking element in its unlocked position, for which purpose an actuating portion of the sliding sleeve cooperates with the locking element.
  • the sliding sleeve is thereby supported on the receiving sleeve, that the sliding sleeve has an inwardly projecting collar at an end remote from the locking element, which engages in an outer circumferential groove which is externally inserted into the receiving sleeve or in the first male part ,
  • This groove forms two axial stops, which limit the Axialverschiebles the sliding sleeve.
  • the dimensioning of the groove is chosen so that the sliding sleeve is so far adjustable within their axial stops that the operating portion of the sliding sleeve can come completely free from the locking element.
  • the receiving sleeve is formed integrally on the first plug-in part, that is, the first plug-in part and receiving sleeve are produced in one piece.
  • the generic plug-in connection thus operates according to the so-called push-pull principle and is designed self-locking for the plug-in process.
  • Another connector of this type is for example from the DE 299 11 792 U1 known, which differs from the connector described above essentially in that the sliding sleeve is biased to its rest position.
  • the present invention is concerned with the problem of providing for a connector of the type mentioned in an improved embodiment, which in particular allows improved handling and is inexpensive to produce.
  • the invention is based on the general idea to exploit the already existing spring force on or in the locking element for the bias of the sliding sleeve in its rest position. This is achieved by an appropriate dimensioning that allows the locking element to drive the sliding sleeve in the rest position on the operating section. By this measure, the locking element receives a double function, so that an additional compression spring for the bias of the sliding sleeve can be saved. This is a tremendous advantage, in particular in the case of a series part of this type, since the production costs can not be increased or only insignificantly increased compared to a conventional plug connection and at the same time the increased operating comfort, the simplified handling and the reduced noise generation with vibrations can be provided.
  • the locking element presses the sliding sleeve against an axial stop defining the rest position of the sliding sleeve.
  • the sliding sleeve automatically assumes its rest position, at least when the connector is loose.
  • the two plug-in parts are coordinated so that the locking element presses against each other in plugged-in plug-in parts in the securing state, ie in particular in the locking position of the locking element, the sliding sleeve against the rest position of the sliding sleeve defining axial stop.
  • This way are also in the mated state defined relative positions between the locking element and plug-in part given, which in particular supports a reduced noise during vibration.
  • the sliding sleeve can be held on the inside of the receiving sleeve on the receiving sleeve.
  • This design thus dispenses with a mounting of the sliding sleeve on the outside of the receiving sleeve, which is advantageous in terms of the reliability of the sliding sleeve, because depending on the application, it can come to the operation of the connector on the outside of the male parts to contamination.
  • contamination can lead to an external holder of the sliding sleeve on the receiving sleeve to the fact that the axial mobility of the sliding sleeve is impaired.
  • the sliding sleeve can fulfill its function, namely the unlocking of the locking element, its axial adjustability must not be compromised.
  • An internal bracket according to the proposed construction has only a reduced risk of contamination.
  • the locking element may be formed as a spring ring which has distributed in the circumferential direction a plurality of latching tabs which protrude inward with a radial component and in the insertion direction resiliently between the locking position and the unlocking position are adjustable, wherein an inner cross-section of the spring ring in the locking position smaller is as in the unlocked position.
  • an electrical plug connection 1 comprises a first plug-in part 2 and a second plug-in part 3.
  • the plug-in connection 1 serves for the electrical connection of at least two electrical lines, which are not shown here for the sake of simplicity.
  • the first plug-in part 2 contains in its interior a first electrical coupling part 4.
  • the second plug-in part 3 contains a second in its interior electrical coupling part 5.
  • the second coupling part 5 is formed as a plug 6, while the first coupling part 4 is formed by a bushing 7.
  • the two coupling parts 4, 5 are complementary to each other, so that the plug 6 and socket 7 in one symbolized by a double arrow plug-in direction 8 are inserted into one another.
  • the plug 6 By inserting the plug 6 in the socket 7, an electrical connection between the coupling parts 4, 5 is made, so that the connected to the coupling parts 4, 5 electrical lines are contacted in a designated manner with each other.
  • the plug 6 may contain, for each line to be contacted, a pin 9 which can be inserted into a matching pin receptacle which is formed in the socket 7 and is not shown here. These pin recordings are then connected in a corresponding manner in each case with the associated line.
  • the first plug-in part 2 has a receiving sleeve 10 which is arranged coaxially relative to the plug-in direction 8 to the first coupling part 4 and which surrounds the coupling part 4 in an annular manner.
  • This receiving sleeve 10 supports a locking element 12 on an inner side 11 facing the first coupling part 4.
  • the locking element 12 is a spring ring in the circumferential direction distributed has a plurality of locking tabs 13 which project from an outer periphery of the spring ring 12 inwardly.
  • the locking element or the spring ring 12 is adjustable between a locking position, which is shown in FIGS. 1, 2 and 4 and an unlocking position which is shown in FIGS. 5 and 6.
  • the locking tabs 13 are resiliently resilient with respect to the insertion direction 8, whereby they can be bent in the direction of insertion 8. In this movement, an inner cross section 14 of the spring ring changes 12. In the locking position, this inner cross section 14 is smaller than in the unlocked position.
  • the locking tabs 13 are inclined here as already in the locking position relative to the plug-in direction 8 and indeed with an inclination angle which is smaller than 90 °.
  • the inclination of the locking tabs 13 is chosen so that the inclination angle additionally decreases when transferring the locking tabs 13 in the unlocked position. By this orientation of the locking tabs 13, the forces required to adjust the locking tabs 13 in their unlocked position are reduced.
  • the design of the spring ring 12 is such that its locking tabs 13 are biased in the locking position. The adjustment of the individual locking tabs 13 in the unlocked position thus takes place against a restoring spring force of the spring ring 12th
  • the first male part 2 is also equipped with a sliding sleeve 15, which is also arranged coaxially with the first coupling part 4, wherein the sliding sleeve 15, the first coupling part 4 surrounds annular.
  • the sliding sleeve 15 has in the preferred embodiment shown here, a substantially U-shaped profile with two different length U-legs.
  • the radially inner U-leg forms an actuating portion 16 of the sliding sleeve 15, while the radially outer U-leg forms a handle portion 17 of the sliding sleeve 15.
  • Handle portion 17 and operating portion 16 are interconnected by a collar 18 which extends transversely to the insertion direction 8, the U-base forms the U-base and is disposed adjacent to a front end 19 of the receiving sleeve 10.
  • the sliding sleeve 15 is slidably mounted on the receiving sleeve 10 in the insertion direction 8. 1 to 4 each show a rest position of the sliding sleeve 15, while FIGS. 5 and 6 represent a release position of the sliding sleeve 15.
  • the actuating portion 16 cooperates with the locking element 12 or with its locking tabs 13.
  • the coupling between the sliding sleeve 15 and locking element 12 takes place so that a displacement of the sliding sleeve 15 in its release position corresponding to FIGS. 5 and 6, the locking element 12 and its locking tabs 13 forces in the release position.
  • the spring force acting on the locking element 12 ensures that this or its locking lugs 13 independently seek to take their locking position.
  • the spring force of the locking element 12 and the locking tabs 13 also causes here that the sliding sleeve 15 is driven by the restoring force of the spring ring 12 in the rest position. Accordingly, the sliding sleeve 15 is automatically moved to its rest position as soon as the locking element 12 can assume its locking position.
  • the locking element 12 may preferably occupy its locking position when the two plug-in parts 2, 3 are completely inserted into one another. In any case, the locking element 12 assumes its locking position as soon as the two plug-in parts 2, 3 are separated or removed from each other.
  • the second plug-in part 3 has a plug-in tube 20, which is arranged coaxially to the second coupling part 5 with respect to the plug-in direction 8 and surrounds it annularly.
  • an annular circumferential locking step 21 is formed on the plug-in tube 20.
  • this locking step 21 is produced in that on the outer side 22 of the plug tube 20, a completely circumferential annular groove 23 is formed, wherein the locking step 21 forms one of the axial boundary walls of the annular groove 23.
  • plug-in tube 20 in which the plug-in tube 20 is made of plastic, can basically to such Latch level 21 and to be dispensed with such an annular groove 23.
  • the two plug-in parts 2, 3 are spaced apart from one another. Immediately before the insertion of the two plug-in parts 2, 3 into each other, they are aligned with respect to the insertion direction 8 in alignment with each other.
  • the second plug-in part 3 is plugged into the first plug-in part 2 so far that a leading, front-side end 24 of the second plug-in part 3 comes into contact with the latching tabs 13.
  • the locking tabs 13 are still in their locked state.
  • the latching lugs 13 are thereby bent over in the plug-in direction, ie in the unlocked position.
  • the preceding axial end 24 of the second plug-in part 3 is inserted into the first plug-in part 2 until it makes contact with a seal 25.
  • This seal 25 is formed here as an O-ring.
  • the second plug-in part 3 has reached its maximum penetration depth into the first plug-in part 2.
  • This maximum penetration depth is defined here by a stop 26 which is formed in the first plug-in part by an annular step on which the preceding axial end 24 of the second plug-in part 3 comes to rest axially.
  • the spring-loaded locking element 12 can now automatically transition into its locking position in the region of the annular groove 23, as a result of which the locking lugs 13 in the annular groove 23 engage behind the locking step 21. This results in a positive securing of the second plug-in part 3 in the first plug-in part 2 against pulling out.
  • the locking element 12 which expediently consists of metal, can be supported with its locking lugs 13 directly on the outside 22 of the plug-in tube 20. Due to the material combination (relatively soft plastic of the plug tube 20 and relatively hard metal of the locking element 12), in this case, in particular in conjunction with relatively sharp-edged locking tabs 13, to a sufficient adhesion between the plug-in parts 2, 3rd
  • the predetermined insertion depth between the plug-in parts 2, 3 is, inter alia, chosen so that in each case a proper electrical contact between the coupling elements 4, 5 is ensured. In other words, the pins 9 reach sufficiently deep into the associated pin recordings.
  • the actuating portion 16 for unlocking the plug-in parts 2, 3 this acts on its, the locking element 12 facing the end with the locking tabs 13 together. Furthermore, the actuating portion 16 may be bevelled at this end with that inclination, which also have the locking tabs 13 in their unlocked position. Also, the inner wall 11 of the receiving sleeve 10 is chamfered adjacent to the locking element 12 according to this inclination.
  • Inner cross section 27 and outer cross section 28 form between the plug tube 20 and receiving sleeve 10 an axial guide. This facilitates the insertion of the plug-in parts 2, 3 finding the connection state.
  • This axial guidance is achieved here by the fact that an inner cross section 27 of the sliding sleeve 15 in the region of its actuating portion 16 is about the same size or slightly larger than an outer cross section 28 of the plug tube 20 is selected.
  • the plug-in tube 20, the receiving sleeve 10 and the locking element 12 are made of metal.
  • the locking element 12 is electrically connected to the outer sleeve 10 radially outside and formed so that it is electrically contacted in the inserted connection state with the plug tube 20.
  • the contact with the plug-in tube 20 takes place over several points which are distributed circumferentially, so that almost an annular contact between locking element 12 and plug tube 20 forms.

  • the plug-in parts 2, 3 are formed in an advantageous embodiment so that they protect the electrical connection of the associated electrical coupling parts 4, 5 from electromagnetic interactions with the environment of the plug-in parts 2, 3 in the connection state.
  • the connector 1 is electromagnetically compatible, so that it can be used in EMVsensiblen installation situations.
  • EMC stands for E tolerability lektro- M agnetician- V.
  • the plug-in parts 2, 3 form so that they shield in the connection state, the electrical connection of the coupling parts 4, 5 against electromagnetic interference and electromagnetic interference of he electrical connection of the coupling parts 4, 5 derived.
  • the shielding and dissipation of electromagnetic interference also improves the electromagnetic compatibility of the connector 1. Electromagnetic interference, which arise in the vicinity of the connector 1, can not act in the electrical connection of the coupling parts 4, 5, nor can electromagnetic interference, which is within the propagate by means of the connector 1 interconnected lines, get from the connector 1 in their environment. The derivation of the electromagnetic interference ensures that the interference can not add up to impermissibly high values.
  • the EMC capability of the connector 1 or the dense shielding of the connector in combination with the immediate dissipation of the interference can be realized in the connector 1 as shown, for example, characterized in that the receiving sleeve 10, the plug tube 20 and the locking element 12 are formed of metal , wherein the locking element 12 is electrically connected to the receiving sleeve 10 and electrically contacted in the connecting state of the plug-in tube 20 circumferentially distributed in several places.
