Definitions

  • the invention relates to an electrical connector part according to the preamble of claim 1.
  • the invention also relates to an electrical connector system with such a connector part.
  • the DE 10 2005 026 148 B4 discloses a connector coupling, in particular for multi-pole electrical line connections, consisting of a first coupling half, which has at least one coupling housing, a contact carrier accommodated therein together with contact elements and a contact carrier and optionally its contact elements at least over part of their axial length, with an external thread for optional screwing on a union nut which is rotatably coupled to a second coupling half or for connecting a region of the coupling housing which is rotatably coupled to a second coupling half and is equipped with means for bringing about a quick locking connection.
  • locking means for quick locking are formed on a partial length of the area of the first coupling housing provided with an external thread located outside the external thread, with which complementary counterparts are assigned on the connecting element, the connecting element of the second coupling half preferably being connected by a threadless Sleeve is formed and held by means of a supported against the housing of the second coupling half loading spring, in particular designed as a corrugated spring loading spring in the axial direction, in particular is held free of play.
  • the corrugated spring is supported on the one hand against an end face of the housing of the second coupling half and on the other hand interacts with a bearing ring supported against a shoulder in the inner peripheral wall of the connecting element of the second coupling half designed as a sleeve, the end face of the housing and the shoulder being in the inner peripheral wall of the sleeve an outer peripheral groove of Form and limit housing.
  • a disadvantage of this known plug connector coupling is that on the one hand the connecting element, which is held in the axial direction by the loading spring without play on the coupling housing, does not have any clearly defined positions in the circumferential direction in relation to the coupling housing of the second coupling half, i.e. it can assume any positions and on the other hand others that an additional part is needed to form the outer peripheral groove of the housing.
  • a resilient ring made of a strip of flat metal which lies in an annular space between a locking sleeve and a sleeve-shaped plug element received therein via a thread and which lies with lugs distributed over the circumference in the inner wall of the locking sleeve and in between alternately on the outer wall of the plug element and the inner wall of the locking sleeve.
  • the ring provides controlled resistance in both directions of rotation as it rotates.
  • the US 4,183,605A an electrical connector having a receptacle that includes a receptacle housing and a plug that includes a plug housing, a coupling that includes a coupling housing that engages a coupling nut for rotating the coupling nut, the coupling nut being in threaded engagement with the plug housing and the coupler housing includes locking means engageable with cooperating locking ridges on the receptacle housing, the plug means and receptacle being adapted to be fully electrically connected and locked together by approximately 90° rotation of the coupler housing.
  • An arcuate locking element from approximately 180° is keyed to the plug housing for relative axial movement and received in an annular groove in the coupling housing for resilient, positive, selective engagement of opposite, radially outwardly enlarged ends of the arcuate detent with two sets of radially outwardly shaped recesses to allow in the clutch housing.
  • Rotating the coupler housing in the opposite direction unlocks the male and female devices and disengages the latching member from the first set of recesses to engage a second set of recesses in the coupler housing, again with audible and tactile feedback as the unlocked position is reached to index.
  • the US 2016/0043482 A1 a plug connector, in particular a coaxial high-frequency plug connector, and a plug connection formed from such a plug connector and a mating plug connector complementary thereto.
  • a connector according to the invention comprises a conductor and a cap nut rotatably mounted on the conductor, the cap nut being resiliently mounted on the conductor in the axial direction of the connector.
  • the US 4,508,407A discloses a self-locking connector in which balls carried by a connector shell are spring biased toward a locking ring rotatable with a coupling nut of the connector.
  • the locking ring is provided with a circular array of detent recesses which the balls engage as the coupling nut is rotated.
  • the balls and recesses are arranged so that only one ball is engaged in a recess at any one time, so that there is a large number of locking positions for the coupling nut.
  • the invention is based on the object of proposing a possibility in which the connecting element designed as a locking sleeve has at least one defined unlocking and locking position in relation to the supporting housing, with reaching or leaving these positions preferably being indicated haptically or acoustically by the user can perceive.
  • the connector part according to the invention has an anti-twist device, which consists of at least one spring element fixed on the outside of the connector part housing and at least one snap-in latch associated therewith and formed on the inside of the locking sleeve. It enables a haptic and acoustic perception at least when the spring element engages in the latch.
  • the spring element is intended to ensure that the locking sleeve does not rotate unintentionally in the open state. This makes so-called “blind plugging” easier for the user, because he has to visually check whether the locking sleeve is in the correct position.
  • the spring element is preferably formed by a projecting bent leaf spring blank and lies immovably in an outer recess of the connector part housing, the projection of the leaf spring blank protruding beyond the outer recess and can thus engage in the catch of the locking sleeve in the locking position of the connector part.
  • the spring element has a latching lug which faces the inside of the locking sleeve and which in the unlocked state of the locking sleeve and in the locked state of the locking sleeve engages in a first snap-in pocket or second snap-in pocket provided for this purpose.
  • the contour between the first locking pocket and the second locking pocket is flat in a first area and rises steeply in a second area near the second locking pocket, with the first area being longer than the second area.
  • the locking lug is engaged in the first locking pocket.
  • the contour is designed flat in the first area so as not to produce any premature noise, such as clicking.
  • the contour rises sharply in the second area, so that the spring element is just about to be fully compressed. If the locking sleeve is turned further, there is a noise (clicking noise) and the connector part is correctly locked with the mating connector part and in position.
  • a guide curve is arranged on the inside of the locking sleeve between the first latching pocket in the unlocked state and the second latching pocket in the locked state, which has a contour which the spring element such keeps under spring tension that the locking sleeve can only be rotated under external force on the locking sleeve.
  • the locking sleeve is held without play in the axial direction on the connector part housing by means of a corrugated spring which engages in an inner peripheral groove of the locking sleeve and in an outer peripheral groove of the connector part housing and is supported against the connector part housing and/or the locking sleeve.
  • the corrugated spring is accommodated in the outer peripheral groove of the connector part housing or in the inner peripheral groove of the locking sleeve in a torsion-proof manner.
  • the corrugated spring lies in a position-fixed position in the circumferential direction in the outer circumferential groove of the connector part housing, it engages rotatably in the inner circumferential groove of the locking sleeve.
  • the corrugated spring engages rotatably in the outer circumferential groove of the connector part housing.
  • the plug part housing and the locking sleeve Due to the material and process, the plug part housing and the locking sleeve have manufacturing tolerances in their dimensions, which are compensated for by the corrugated spring by the corrugated spring being inserted with pretension, ie compressed, into the outer circumferential groove of the plug part housing and into the inner circumferential groove of the locking sleeve.
  • the connector part preferably has a corrugated spring which is open in the circumferential direction and has a spring gap. This is designed to be flexible in the circumferential direction and can thus be easily inserted into the inner peripheral groove of the locking sleeve and in the outer peripheral groove of the connector part housing in order to hold the locking sleeve and the connector part housing together.
  • the corrugated spring has wave crests in the axial direction and wave troughs in between. The width of the spring gap of the corrugated spring can change if pressure is applied to the corrugated spring in the axial direction, ie the height of the wave crests or the depth of the wave troughs changes.
  • the height of the wave crests and the depth of the wave troughs are larger than a groove width of the outer peripheral groove of the connector part housing and the inner peripheral groove of the locking sleeve. As a result, it rests against both edges of the outer peripheral groove of the connector part housing and the inner peripheral groove with the same clamping force.
  • Dimensional tolerances of the corrugated spring itself are irrelevant. In any position of the locking sleeve relative to the connector part housing, there is sufficient clamping force that makes it difficult for the locking sleeve to change position relative to the connector part housing. As long as the preload of the corrugated spring is greater than the load from an oscillation amplitude, the system does not require any further friction brake, for example in the form of an elastic ring element.
  • the connector part has the outer peripheral groove of the connector part housing or the inner peripheral groove of the locking sleeve at least one positioning web for the corrugated spring, which is preferably arranged on a side flank of the outer peripheral groove or a side flank of the inner peripheral groove. It goes without saying that such a web must not be present in both grooves, since this would not allow the locking sleeve to rotate on the connector part housing. Instead of being arranged on the side flanks of one of the two grooves, the positioning web can also protrude from the bottom of these grooves.
  • the corrugated spring is preferably aligned with respect to the connector part housing or the locking sleeve in such a way that the positioning web passes through the spring gap and thus fixes the corrugated spring so that it is secured against rotation.
  • the corrugated spring is advantageously aligned with respect to the connector part housing or the locking sleeve in such a way that the at least one positioning web extends in a trough of the corrugated spring. In this way, too, the corrugated spring can be secured against rotation in the circumferential direction in the circumferential direction without play or with play the locking sleeve or in the outer peripheral groove of the connector part housing.
  • the positioning web in the wave trough can also preferably form a compression limiting web for the wave spring, which limits an axial compression path of the wave spring.
  • a compression limiting web in a trough can be present in addition to a positioning web penetrating the spring gap.
  • the side flank of the inner peripheral groove of the locking sleeve or the side flank of the outer peripheral groove of the connector part housing is wavy in the connector part, with the contour of the side flank preferably being adapted to the shape of the corrugated spring.
  • the corrugated contour is of course realized in that inner peripheral groove of the locking sleeve or the outer peripheral groove of the connector part housing in which the positioning web described above is not formed, which holds the corrugated spring against rotation.
  • This increases the axial spring deflection when the locking sleeve is twisted relative to the connector part housing, so that loading the corrugated spring with a larger vibration amplitude does not lead to an unwanted twisting of the locking sleeve on the connector part housing, and the locking of the connector part with a mating connector part is particularly secure is.
  • This is particularly beneficial in that the wave height of the corrugated spring is greater than a width of the outer peripheral groove of the plug part housing or the inner peripheral groove of the locking sleeve, and the corrugated spring is inserted axially compressed into the outer peripheral groove and/or the inner peripheral groove.
  • the at least one locking means of the locking sleeve and the at least one counter-locking means of the counter-locking section are preferably designed as a full thread, as a partial thread segmented in the circumferential direction or in the manner of a bayonet catch or bayonet lock.
  • the locking sleeve and the counter-locking section engage at least partially axially in one another and can be releasably fixed to one another by turning the locking sleeve.
  • the at least one locking means of the locking sleeve can be formed on the outside or inside of the locking sleeve.
  • the at least one counter-locking means designed to be complementary thereto is correspondingly mutually formed on the counter-locking section of the mating connector part.
  • the connector part has rotary stops on the locking sleeve and the connector part housing, which limit the rotational movement of the locking sleeve relative to the connector part housing.
  • rotary stops on the locking sleeve and the connector part housing which limit the rotational movement of the locking sleeve relative to the connector part housing.
  • the rotary stops of the locking sleeve are preferably formed by axially extending longitudinal walls of a sleeve inner recess and the rotary stops of the plug part housing are formed by longitudinal flanks, preferably of a radially projecting outer housing pin.
  • the circumferential width of the inner sleeve recess is significantly larger than the corresponding width of the outer spigot of the housing. They are preferably selected in such a way that an unlocking position and a locking position are realized, between which the locking sleeve can be rotated.
  • the unlocked position and the locked position are separated from each other by a typical angle of rotation of about 30 to 100 degrees.
  • one longitudinal flank of the outer housing spigot is in contact with the associated longitudinal wall of the inner sleeve recess, and in the locking position the other longitudinal flank of the outer housing spigot is in contact with the other longitudinal wall of the inner sleeve recess.
  • the electrical plug-in connection system with a plug-in connector part, which has a locking sleeve rotatably mounted on a plug-in part housing and with a mating connector part, which has a tubular mating locking section, which is associated with the locking sleeve and is formed on a mating connector part housing, for releasably fixing the connector part on the mating connector part, comprises a connector part with at least the features of claim 1.

It is immovably fixed to the connector part housing 3 on the outside and acts with one in the figure 9 visible catch 15 together.

  • the corrugated spring 11 is held in the outer peripheral groove 17 of the connector part housing 3 against rotation and in an inner peripheral groove 18 of the locking sleeve 4 rotatably.
