Definitions

  • the invention relates to a connector with two connector halves, in particular in the form of a pin connector and a socket connector, each having an insulating housing and a contact arrangement held thereon, which can be connected to the contact arrangement of the other insulating housing, and with a locking device which has at least one in the direction of insertion extending bolt on one connector half and at least one receiving sleeve for the bolt on the other connector half, the bolt having a substantially perpendicular to the direction of the circumferential groove into which a resilient or spring-loaded locking member movable through an opening in the receiving sleeve transversely to the direction of insertion can be snapped into place.
  • Such an electrical connector which may be designed as a circuit board or cable connector, is known from DE 40 13 682 A1.
  • the locking member is formed by a plate-shaped slide element that can be moved manually transversely to the plugging direction. In the unactuated state, the slide element engages through the opening in the receiving sleeve from one side into the clear cross section of the receiving sleeve.
  • the slide element is displaced or deflected by a conical insertion bevel of the free end of the bolt from the clear cross-section of the receptacle, so that the bolt inserted into the receptacle sleeve with essentially no play can be inserted past the slider element into the receptacle sleeve.
  • the spring-loaded slide element engages with an edge area in the groove and secures or locks the bolt in the receptacle, so that the connector cannot be released even when the connector halves are pulled apart .
  • the invention is therefore based on the object of improving a plug connector of the type described above in such a way that it is easier to use than known plug connectors in confined handling conditions and with limited accessibility.
  • the locking member is formed by a spring clip and the locking device can be achieved without requiring manual actuation of the locking member by the spring clip being radially widened when the two connector halves are pulled apart, and thereby snaps out of the groove.
  • the solution according to the invention offers the advantage over the known solution that a user only needs to pull the two connector halves apart to release the plug connection without additionally having to actuate the locking member - in the known connector the slide element - in the direction transverse to the plugging direction.
  • the spring clip is essentially U-shaped and is held in a plane substantially perpendicular to the direction of insertion on the receiving sleeve in the region of its preferably slot-shaped opening.
  • the receiving sleeve has two substantially opposite openings for engagement of the spring clip, so that both legs of the spring clip can contribute to the locking according to the invention.
  • This embodiment of the invention has the advantage over the known connector that the bolt is held or secured on two preferably opposite circumferential sections of the groove.
  • the spring clip can be economically manufactured or bent from a wire section.
  • the receiving sleeve has a circumferential groove for receiving the arc area of the U-shaped spring clip.
  • the free ends of the legs of the spring clip can be bent towards one another in a particularly simple manner in this case, so that the spring clip, when properly arranged on the receiving sleeve, is resilient in the radial direction but cannot be detached from the receiving sleeve when used as intended.
  • the bolt which can be inserted into the receiving sleeve can additionally be secured in the receiving sleeve by means of a screw connection;
  • the bolt has a threaded bore on its end face into which a screw of a conventional connector half on the sleeve side can be screwed.
  • the bolt-side connector half can thus be connected both to a connector half formed according to the invention with a spring clip and to a known connector half having a screw connection.
  • the spring clip has a round cross-section and in the locked state only "dips" up to half its thickness or less into the circumferential groove of the bolt, it is possible to form the groove at right angles when viewed in cross-section, since in this case the spring clip when the connector halves are pulled apart snaps out of the groove. If, on the other hand, the spring clip is non-round in cross section or "dips" deeper than half its thickness into the circumferential groove of the bolt, it proves to be advantageous if the front groove wall of the circumferential groove of the bolt has an outer area which is bevelled to the bolt jacket and over which the spring clip can slide or snap out of the groove when the connector halves are pulled apart and can thus release the lock.
  • the pin-side connector half of a connector according to the invention is designed such that the front groove wall of the circumferential groove of the pin has an outer area which is chamfered towards the pin jacket and inclined to the direction of insertion and an inner area which is essentially perpendicular to the direction of insertion.
  • a bolt-side connector half offers the advantage that it can be connected both to the other connector half according to the invention and to a connector half known from DE 40 13 682 A1 mentioned at the beginning with a slide element which can be moved transversely to the plugging direction.
  • the edge region of the slide element engaging in the circumferential groove of the bolt bears against the inner region, which is essentially perpendicular to the direction of insertion, and is secured by it.
  • the lock cannot be released, but instead the slide element must be deflected transversely to the direction of insertion from the circumferential groove of the bolt.
  • the described bolt-side connector half can also be connected to a socket-side connector half with a spring clip; In this case, the spring clip snaps into the groove, as described at the beginning, and slides out of the groove when the connector halves are pulled apart over the bevelled outer wall region of the circumferential groove.
  • a preferred connector-side connector half has two U-shaped spring clips, the open sides of which are arranged facing each other. This ensures that the spring clip interacts with another groove area of the bolt than a slide element of a corresponding connector half. If only one sleeve and one bolt are provided, the spring clip can be used also be arranged so that it engages in a different groove area than a slide element.
  • the connector half 2 shows a connector half 2 designed as a printed circuit board connector and a connector half 4 designed as a cable connector.
  • the connector half 2 comprises an insulating housing 6 for receiving contact wires 8 connected to the printed circuit board, which lead to a contact arrangement 10.
  • the connector half 4 comprises an insulating housing 12, in which wire ends, not shown, lead to a contact arrangement 14 which can be connected to the contact arrangement 10.
  • a locking device designated overall by reference numeral 16, comprises two bolts 18 held on the insulating housing 6, and two receiving sleeves 20 for the bolts 18 arranged on the insulating housing 12.
  • the receiving sleeve 20 has two slot-shaped openings 22 lying opposite one another .
  • a U-shaped spring clip 24 engages in the clear cross-section of the receiving sleeve 20, as can also be seen from FIGS. 3 and 5.
  • the receiving sleeve 20 is also provided in the region of the openings 22 with a circumferential groove 26 (FIG. 3) into which the spring clip 24 engages.
  • the bolt 18 has a threaded bore 28 running in the longitudinal direction of the axis; the bolt 18 can therefore be used for locking with a known screw-lockable connector half. Furthermore, the bolt 18 has a conical insertion bevel 30 and a circumferential groove 32 running perpendicular to the direction of insertion. A front groove wall 34 of the circumferential groove 32 in the insertion direction has an area 36 which is beveled towards the front end of the bolt 18 and which merges with the groove base 38 into a wall area 40 perpendicular to the insertion direction.
  • the pin 18 When the pin 18 is inserted into the receiving sleeve 20 when the two connector halves are connected, the pin 18 is centered by the insertion bevel 30, and the spring clip 24 is displaced from the clear cross section of the receiving sleeve 20 and then slides on a jacket section 42 of the pin 18. If If the groove 32 reaches the area of the slot-shaped openings 22 in the receiving sleeve 20, the spring element 24 snaps into the circumferential groove 32 of the bolt 18 via the beveled groove edge area 34 and thus locks the two connector halves. Only when the two connector halves 4, 8 are pulled apart with sufficient force does the spring clip 24 again snap over the inclined groove wall area 34 sliding out of the groove 32, and the connector halves can be separated, the spring clip 24 in turn sliding on the peripheral region 42 of the bolt 18.
  • the circumferential groove 32 or its groove bottom 38 is step-shaped, a front and radially inner step region 44 being delimited by the groove wall region 40 which is essentially perpendicular to the direction of insertion.
  • the connector half 2 designed in this way can be used with the connector half known from DE 40 13 682 A1 with a sliding lock, which is shown in FIG. 6.
  • the locking device 48 of this connector half 46 comprises a locking spring 50 held on the insulating housing of the connector half 46, which merges into a plate-shaped slide element 52.
  • the slide element 52 comprises two openings 54 and 56, through which receiving sleeves 58 and 60 extend.
  • the slide element 52 can be deflected in the direction of the arrow 62.
  • edge regions 64, 66 In the unactuated state, it engages with edge regions 64, 66 in through a circumferential opening 68 or 70 in the clear cross section of the receiving sleeves 58 or 60. If the connector half 2 with stepped circumferential groove 32 of the bolt 18 is now connected to the known connector half 46, the slide element 52 with the edge areas 64, 66 engages in the front step area 44 delimited by the groove wall area 40 running perpendicular to the direction of insertion and locks the plug connection . The edge regions 64, 66 then bear against this groove wall region 40, which runs perpendicular to the insertion direction. Only when the slide element 52 is deflected to the right in FIG. 6 and the edge regions 64, 66 of the slide element 52 are disengaged from the circumferential groove 32, can the connector halves 2 and 46 be pulled apart.
  • FIG. 5 shows the U-shaped spring clip 24 as an individual part.
  • the spring clip 24 includes an arcuate portion 72 and leg portions 74 and 76.
  • the free ends 78 and 80 of the leg portions 74, 76 are bent towards each other, thereby preventing the Spring clip 24 detaches from the receptacle sleeve 20 when it is arranged as intended.
  • the leg region 74 is bent upwards from the clamp plane 82 and the leg region 76 is bent downwards.
