Definitions

  • the invention relates to a circular connector, consisting of a grip sleeve with a screw-in contact carrier from the plug-side end, and a screw nut provided for screwing with a mating connector, which is pushed axially from the cable-side end onto the contact carrier and then rotatable with inwardly projecting projections in an annular groove is held, which is formed by a plug-in closed first ring collar and a second, cable-side ring collar of the contact carrier provided with adapted recesses for the passage of the projections.
  • Such a circular connector is known from catalog CC 1 from Amphenol-Tuchel-Electronics GmbH, Heilbronn, from October 1984 and is shown and described there under the name "Series C 16-1".
  • the invention is therefore based on the object of developing the known run plug connector in such a way that the contact carrier can be screwed into and out of the handle sleeve by hand without tools, and an unwanted unscrewing of the handle sleeve from the contact carrier when loosening the connector Union nut is permanently safely avoided by the mating connector.
  • the contact carrier has at least one radially resilient tongue which can be pressed into a recess in the second ring collar and ends in a radially outwardly projecting nose which engages in one of the recesses on the inner surface of the plug-side end part of the grip sleeve when the circular connector is fitted, -
  • the projections each have a plug-in surface which extends obliquely towards the inner wall of the union nut and is at least as wide as the nose of the tongue.
  • the union nut is first pushed onto the cable end of the contact carrier when the circular connector is installed. This is possible because the tongues move inwards by sliding their teeth onto the inclined surfaces of the projections. So that this process can be carried out safely and without great effort even under unfavorable circumstances, it is advisable to round off or bevel the nose edges resting on the inclined surfaces. As soon as the lugs have slid over the protrusions, the tongues snap back a little due to their own spring action. In this position, the projections of the union nut are form-fitting with the second ring collar, so that the two connector parts, namely union nut and contact carrier, cannot be rotated relative to one another and this creates a driving effect.
  • the grip sleeve can be held by holding the union nut without additional work or without the mating connector serving as a holding tool, simply and securely screwed onto the contact carrier.
  • assembly is further facilitated by the fact that the union nut can be pressed in the direction of the cable connection, the projections resting against the end faces of the lugs on the plug side.
  • the union nut is moved further in the direction of insertion on the contact carrier until its projections engage in its annular groove and are freely rotatable therein.
  • the circular connector can now be screwed together with the mating connector using the union nut.
  • the tongues now spring completely outwards and engage with their noses in the recesses, which are distributed over the circumference on the inner surface of the plug-side end part of the grip sleeve. In this way, the grip sleeve is locked on the contact carrier after assembly and twisting of the contact carrier to the grip sleeve is effectively prevented.
  • the inner surface of the plug-side end part of the grip sleeve for forming the recesses is thus formed as a sawtooth-shaped ring gear, the teeth of which one after the other, each with a front face clockwise flat and steeply falling tooth flank, the radially outwardly projecting nose engages in one of the gaps between two teeth of the ring gear when the circular connector is fitted.
  • the nose can already engage in the recess now formed as gaps between two teeth when the union nut is still in a position in which the tongue is at least partially pressed radially inward.
  • the sawtooth-shaped ring gear thereby allows the grip sleeve to be screwed onto the contact carrier, but prevents an opposite rotation, so that the sawtooth-shaped ring gear in cooperation with the nose of the resilient tongue has the effect of a ratchet.
  • the tongue is formed in one piece with the contact carrier. This results in simple and inexpensive production.
  • the radially resilient tongue can be connected to the contact carrier in the recess of the second collar itself or in the annular groove between the first collar and the second collar of the contact carrier.
  • a further advantageous embodiment of the invention is to choose the width of the second ring collar at least as large as the screw-in depth of the contact carrier in the grip sleeve. In this way it is ensured that the union nut is positively connected to the contact carrier until the grip sleeve is completely screwed on.
  • the spring action of the tongue can be further improved according to a further embodiment of the invention in that the Tongue at the base has approximately the width of the recess and tapers towards the width of the nose towards the free end. This results in stable and good spring properties with low material expenditure.
  • the tapering of the tongue towards the nose can be trapezoidal, for example.
  • a further embodiment of the invention consists in providing two tongues which are offset by 180 ° to one another, as a result of which jamming during assembly of the plug is avoided.
  • the contact carrier 1 shown in FIG. 1 is the contact carrier for the contact sockets, which are arranged in a contact socket body 2 provided with an alignment groove.
  • This contact socket body 2 is followed by a first sealing ring recess 3 on the cable side, which is delimited on the cable side by a first ring collar 4.
  • the second collar 5 has at least one recess 7, as shown in FIG. 1. Two of these recesses can also be provided, which lie opposite one another, i.e. are offset from each other by 180 °. Embodiments with four recesses that are opposite each other, that is offset by 90 °, are also possible.
  • a second direct ring recess 8 adjoins the cable, which is delimited on the cable side by a thread 9, onto which a grip sleeve can be screwed.
  • a tongue 10 which, in the present exemplary embodiment, projects from the first collar 4 to the cable side and, viewed axially, projects into the recess 7 of the second collar 5.
  • the tongue 10 thus springs in the radial direction of the contact carrier.
  • a radially outwardly protruding nose 11 which, as will be explained in the following, is chamfered.
  • Such a tongue 10 with a nose 11 is also provided in the same manner in an identically designed, opposite recess in the second annular collar 5.
  • the union nut 20 is shown in a partially sectioned side view or in plan view from the contact-side end.
  • four inwardly projecting projections 21 are formed inside the union nut 20, which protrude inwards from an annular collar 22 in this exemplary embodiment.
  • the protrusions 21 have the best can be seen on the left side of FIG. 2, inclined surfaces 23, each of which rises inwardly towards the cable side.
  • the circular connector in addition to the contact carrier 1 and the union nut 20 already described, has a grip sleeve 41 with a cable screw connection 42.
  • saw teeth 43 are formed on the inner surface of the plug-side end part of the grip sleeve 41, which form a toothed ring 44.
  • the ring gear 44 is best seen in FIG. 5.
  • the teeth each have a tooth flank 45 which rises gently in a clockwise direction when viewed from the front and a steeply falling tooth flank 46.
  • the union nut 20 is pushed onto the contact carrier 1 from the cable end.
  • the projections 21 of the union nut 20 are not already randomly aligned with the recesses 7 in the second collar 5 of the contact carrier 1, the projections 21 of the union nut 20 abut the cable-side end of the second collar 5 of the contact carrier 1.
  • the projections 21 of the union nut 20 get into the recesses 7 of the second annular collar 5 of the contact carrier 1.
  • the lugs 11 of the contact carrier 1, which protrude radially from the tongues 10, abut the oblique surfaces 23 of the projections 21 of the union nut 20 (see FIGS. 1, 2 and 4).
  • the shape of the projections 21 of the collar 22 in the union nut 20 and the recesses 7 in the second collar 5 of the contact carrier 1 must be designed such that the projections 21 of the union nut 20 into the recesses 7 of the second contact ring 5 of the contact carrier 1 fit. Because only then is it possible to push the union nut 20 onto the contact carrier 1.
  • the number of projections 21 on the collar 22 of the union nut 20 can be chosen as desired, for example only one projection 21 is sufficient, although four projections are provided in the present exemplary embodiment.
  • the recesses 7 of the second collar 5 of the contact carrier 1 need only correspond in number and position to the number and position of the projections 21 on the collar 22 of the union nut 20.
  • a tongue 10 is provided only in two recesses 7 of the second ring collar 5 of the contact carrier 1, although four projections 21 are formed on the ring collar 22 of the union nut 20 (cf. FIG. 3).
  • the number, shape and shape device of the projections 21 of the union nut 20 and the recesses 7 of the second collar 5 of the contact carrier 1 can be chosen by the person skilled in the art depending on the present requirements.
  • the union nut 20 can be moved with respect to the contact carrier 1 to the cable side up to the stop of the annular collar 22 against the lugs 11 of the tongues 10 of the contact carrier 1.
  • the tongues 10 are designed so that they are pressed somewhat inwards.
  • the handle sleeve 41 can therefore be screwed onto the thread 9 of the contact carrier 1 as far as it will go without the lugs 11 of the tongues 10 of the contact carrier 1 touching the teeth 43 of the ring gear 44 on the inner surface of the plug-side end part of the handle sleeve 41.
  • the handle sleeve 21 can be freely screwed on and off on the contact carrier 1 because the radial pressing in of the tongues 10 thereby results in no contact between the tongue lugs 11 of the contact carrier 1 and the ring gear 44 of the grip sleeve 41.
  • the union nut 20 can now ge to the contact side are moved relative to the contact carrier 1, whereby the tongues 10 are released and the tongue lugs 11 engage in the spaces between the ring gear 44, as can best be seen from FIG. 5.
  • the grip sleeve 41 is locked on the contact carrier 1, so that there is no danger that the grip sleeve 41 will be unscrewed from the contact carrier 1 when the union nut 20 in the contact-side position, as shown in Fig. 4, from the thread of the Mating connector is turned off.
  • the collar 22 of the union nut 20 can rotate freely in the annular groove 6 of the contact carrier 1 and thus the union nut 20 with respect to the contact carrier 1, wherein in this position of the union nut 20 the tongue lugs 11 simultaneously locking between the teeth 43 of the ring gear 44 the grip sleeve 41 lie.
  • the tongue lugs 11 of the contact carrier 1 engage in the recesses 47 between the teeth 43 of the ring gear 44 of the grip sleeve 41 when the tongue 10 is released by the union nut 20, i.e. if the projections 21 of the union nut 20 are not in the recesses 7 of the second ring collar 5 of the contact carrier 1, the union nut 20 is thus freely rotatable on the contact carrier 1.
  • a ring with repeating recesses can also be provided on the plug-side end part of the inner surface of the grip sleeve 41, the tongue lugs 11 then engaging in these recesses.
  • a ring gear 44 with teeth 43 in the manner described has the advantage that the tongue lugs 11 can also engage between the teeth 43 of the ring gear 44 of the grip sleeve 41 when the union nut 20 is in the cable-side position with respect to the contact carrier 1 located.
  • the ring gear 44 then acts together with the tongue 11 as a ratchet, so that the grip sleeve 41 can be screwed on, but unscrewing the grip sleeve 41 is not possible.
