Definitions

  • the invention relates to an electrical connector, one of which Half a at least one contact carrier, a pull-out protection for a cable and housing housing contact parts, which on the one hand towards the cable entry is covered by a cap and on the other hand over part of its axial Extension from one end of the housing, which also protrudes beyond the housing Comprehensive contact carrier to secure the coupling of one connector half with a second connector half having an internal thread Union nut is surrounded, the union nut over at an axial distance each other on the housing, formed by radially projecting ring webs formed plain bearing areas rotatable about the longitudinal axis of the housing in the axial Direction but supported immovably on the housing and by means of only one Secure against unintentional overcoming by increased effort Twisting in the release direction is secured.
  • a union nut is rotatably mounted on the housing of a first connector half which can be connected to a second connector half, the union nut being assigned latching means which prevent the union nut from being inadvertently rotated.
  • the latching means consist on the one hand of a detent ring and on the other hand of counter detents engaging in the detents of the detent ring.
  • the snap ring is formed on the inner circumference of a plastic ring inserted into an annular groove formed at the rear end of the union nut facing the cable entry, the plastic ring being held in the annular groove of the union nut by means of a snap arrangement.
  • the counter-locking means cooperating with the locking ring are formed by noses which are formed on the outer circumference of the housing and protrude radially therefrom and which are in constant engagement with the detents of the locking ring inserted into the union nut. Since, in this embodiment, both the plastic ring having the catches and the housing of the connector must be made of a plastic material, this anti-rotation device can only be overcome as intended by an increased expenditure of force sufficient for compressing the interlocking catch means.
  • a housing consisting of two parts which can be connected via a screw connection over two spaced-apart length sections each is equipped with a circumferential toothing designed as a saw toothing, a first saw toothing preventing the unintentional loosening of the mutual screwing of the two parts of the housing and a second saw toothing preventing the unintentional loosening of a screwable part of the housing which closes the housing to the cable entry Serves cap.
  • the desired or intended anti-rotation lock is to be achieved in that the cap is pressed with its inner circumference into the circumferential toothing of the housing, which naturally makes it extremely difficult to detach the cap from the housing without damage or requires the removal of a large part of the connector.
  • Such a design of anti-rotation locks based on a deformation or compression of at least one of two interlocking locking means interacting with one another is fundamentally not suitable for a rotationally secure fixing of a union nut which is rotatably mounted on the housing of a plug connector as a result of an increased effort.
  • Each of the two known anti-rotation devices for components of electrical connectors or connector halves is based on the use of the deformation resistance of a plastic material as a holding means and therefore requires a correspondingly large amount of force in both directions of the union nut for inserting and overcoming the anti-rotation device, which places an additional burden on the Assembly personnel.
  • the invention is based on the state of the above Technology based the task one with a low technical and economical producible, with only a very slight increase in the required Force-engaging, damage-free a variety of Changing the locking positions enables the anti-rotation lock for those on the housing of the connector bearing nut to create, which itself furthermore characterized by the fact that they do not enlarge the dimensions the connector brings with it.
  • This object is essentially achieved in that the Securing the union nut against unintentional turning in the loosening direction in a between two axially spaced, by radial protruding ring webs of the housing formed slide bearing areas free annulus is housed and one at a part, housing or Union nut with all-round saw toothing and at least one with this cooperating spring-loaded locking lug.
  • the anti-rotation device according to the invention is used as intended for plug connectors which are exposed to constant shocks and, above all, high vibrations during operation, in particular for those connector halves which have to be connected to installation boxes which produce shocks and vibrations and in which the plug connection is secured in an independent manner Union nut must be prevented by the influence of shocks or vibrations.
  • the insertion of the anti-rotation device associated with the screwing of the union nut onto the threaded part of the other connector half can be carried out with the smallest possible increase in the force required for the production of the screw connection between the two connector halves .
  • the use of a spring for loading the locking lug in the direction of engagement allows the force required to insert the anti-twist device to be limited to a very small amount, in particular to a much smaller amount than this would be possible through a selection of compressible materials for the design of an anti-rotation device.
  • the desired goal is particularly suited to a design in which the amount of load on the locking lug with a spring load is at least essentially limited to securing engagement between the locking lug and the saw toothing and the retention effect achieved mainly by the steepness of the tooth flanks of the saw toothing and the locking lug interacting in the release direction becomes.
  • the inventive accommodation of the anti-rotation device in an already existing cavity of the connector half also ensures that no expansion of the size of the connector is required for the assignment of the anti-rotation device.
  • an anti-rotation device for a rotatable it is provided on the housing of the one half of the connector, that the saw toothing all around on the inner circumference of the union nut formed and the at least one cooperating with the saw toothing Latch by means of a resiliently elastic, acting in the manner of a leaf spring deformable support arm is supported against the housing.
  • the two spring bridges each have an amount corresponding to an approximately thickened width between the tapered length section of the receiving sleeve and the tip circle of the saw toothing of the union nut, and both ends have an equally thickened end area
  • the interacting with the saw toothing Locking lugs are each arranged on a bow-shaped area tapered to form a resiliently elastically deformable support area between two thickenings of each spring bridge.
  • the two spring bridges can in each case be fixed to the receiving sleeve by means of a pin which is fixed thereon and engages in a bore recess in its thickened central region.
  • This configuration results in a particularly reliable support of the latching lugs against the housing or the tapered region of the receiving sleeve, even if the bracket-shaped areas which support the latching lugs in an elastically elastic manner are thin-walled to ensure only a weak loading of the latching lugs with spring force. This means that the insertion of the locking device against unintentional rotation, which is associated with the tightening of the union nut, can be accomplished with very little effort.
  • a high resistance of securing the union nut against unintentional rotation in the opening or loosening direction is generated in that, in conjunction with a complementary design of the locking lugs, the teeth of the saw toothing are designed asymmetrically in a manner known per se, such that the the Establishing the screw connection with the other direction of rotation associated with the direction of rotation of the union flanks facing the tooth flanks and the flanks facing the opposite direction of rotation of the union flanks have a steep pitch.
  • the connector half shown in FIG. 1 has a metallic housing 1 in which a contact carrier 4 composed of two parts 2 and 3 is included and in which another spacer 5 and a strain relief 6 used for a cable not shown in the drawing are.
  • a large number of individual contacts 7 are inserted into the contact carrier 4.
  • the Contact carrier 4 projects with its free end 8 that of the associated second one Connector half facing the end of the housing 1. That the cable entry facing end of the housing 1 is covered by an attached end cap 9.
  • the end cap 9 is fastened to the housing 1 by means of screw bolts 10, such that in the assembled state housing 1 and end cap 9 are rigid Form unity.
  • the housing 1 is over its remaining extent one in the area of their overlap with the housing 1 as a cylinder sleeve trained cap nut 11, which on to radially projecting the housing 1 connected ring webs 12 arranged slide bearing areas 13 rotatably supported about its longitudinal axis and for connection to a in the drawing, not shown, the second connector half in your that Housing 1 protruding length section equipped with an internal thread 34 is.
  • the housing 1 has two axially Distance from each other arranged slide bearing areas 13, in which the free end of the connector half adjacent slide bearing area 13 a fuse 14 against axial displacement of the union nut 11 relative to the Housing 1 is housed.
  • the fuse 16 includes in the embodiment shown, one on the inner circumference 17 of the cylinder sleeve trained length section of the union nut 11 arranged circumferentially Saw toothing 18 and locking lugs 19 cooperating therewith.
  • the locking lugs 19 are on spring bridges designed as semicircular shaped parts 20 formed, the spring bridges 20 on the tapered area 21 are supported by a support collar 22 which is offset from the support collar 22.
  • the molded parts forming the spring bridges 20 have in their central section 24 one of the clear width of between the tip circle of the saw teeth 18 and corresponding to the tapered area 21 of the receiving sleeve 23 remaining annular space Material thickness on such that they in their central portion 24 over a limited inner circumferential section area on the tapered area 21 of the receiving sleeve 23 rest.
  • the spring bridges 20 In the area of its middle section 24 are the spring bridges 20 via an engaging in a bore recess 25 Pin 26 fixed to the tapered area 21 of the receiving sleeve 23.
  • the spring bridges 20 forming molded parts also have at both ends short lengths 27, the material thickness of the clear width of between the tip circle of the saw toothing 18 and the tapered region 21 of the Receiving sleeve 23 corresponds to the remaining annular space. Over these lengths 27 are the molded parts forming the spring bridges 20 also on the tapered area 21 of the receiving sleeve 23.
  • the locking lugs 19 are on the Distances between those abutting the tapered area 21 of the receiving sleeve 23 Regions 24 and 27 of the molded parts forming the spring bridges 20 thin-walled and bow-shaped connections 28 arranged, wherein the degree of thinness of the bow-shaped connections the degree of exposure the locking lugs 19 determined with a spring load.
  • teeth 29 of the saw toothing 18 and the locking lugs 19 each have a non-symmetrical cross-sectional shape on, in that the direction of rotation of the union nut 11 in Tooth direction facing tooth flanks 30 of the saw teeth 29 and the latter Flanks 31 of the locking lugs 19 directed in the same direction are designed to rise flatly are, so that the locking lugs 19 when tightening the screw between two connector halves to be connected with the least Slide resistance over the teeth 29 of the saw toothing 18.
