Definitions

  • the invention relates to a connector assembly
  • a connector assembly comprising a first connector part with a cylindrical wall with at least one locking element and a second connector part with a rotatable ring with a screw thread path for each locking element, said components being integrally made of plastic material, wherein in the coupled position of the connector parts each locking element is in an end position in the screw thread path and each locking element is axially spring-biased against a side of the screw thread path, wherein means are provided for signalling the reaching of the end position.
  • Such a connector assembly generally indicated as connector with locking of the bayonet type is known in various embodiments and for example disclosed in US patent 3,901,574 and French patent application 2.632.783.
  • bosses are provided in the screw thread paths on the cylindrical wall of the first connector part, while the ring at its inner wall supports the locking elements adapted to pass these bosses for reaching the end position by deformation of the ring.
  • the locking elements consist of lugs which are brought into the end position by deformation of the rotatable ring.
  • slots and thinned wall parts are provided in the same, whereby manufacturing the ring becomes complicated.
  • the locking elements made as pins are rather vulnerable and are subject to wear.
  • the invention aims to provide an improved connector assembly of the above-mentioned type, which can be manufactured in a simple manner and wherein reaching the end position of the locking elements does not require any deformation of the ring.
  • each locking element is made as a rib extending in accordance with the screw thread path and in that the screw thread path is determined by at least a first lug, wherein the side of the rib cooperating with the lug during coupling the connector parts is provided with a staggered portion.
  • a connector assembly is obtained, which can be manufactured in a relatively simple manner because it is not necessary to form complete screw thread paths, whereas on the other hand by providing a staggered portion in a side of the rib transverse to the axial direction the spring force operating in axial direction is advantageously used for locking the ring in the end position and for signalling the reaching of this end position.
  • the ribs are relatively solid due to their length and are adapted to take a high load.
  • the ring 3 of the connector part 2 is located on this connector part in the assembled position, wherein a bayonet spring ring 7 is enclosed between a collar 8 of the connector part 2 and a collar 9 of the ring 3.
  • the ring 3 comprises three screw thread paths 10 for the locking elements 5, wherein each screw thread path is determined by three lugs 11, 12 and 13 formed on the inner wall of the ring 3.
  • each two first lugs 11 successive in circumferential direction determine an axial inlet slot 14 in which a locking element 5 can be received fittingly.
  • the lugs 12 and 13 are lying on both sides of the lug 11 in circumferential direction, whereas in axial direction the lug 11 and the lugs 12, 13 are lying on both sides of the screw thread path 10. It is indicated in Figs. 1 and 4 that the lugs 13 are bevelled at the side directed towards the connector part 1 so that the bayonet spring ring 7 can be mounted easily in the ring 3.
  • the locking elements 5 are inserted into the inlet slots 14 in a manner as shown in Fig. 4A and subsequently the ring 3 is rotated into the end position shown in Fig. 4C. During this rotation the side 15 of each locking element 5 is pressed against the side 16 of the corresponding lug 11 by the occurring forces and the operation of the bayonet spring ring 7. As appears from Fig. 4B, the sides 15 and 16 engage each other along a great length so that a relatively high force can be taken.
  • a staggered portion 19 and 20, respectively, is provided in this end part 17, 18, said staggered portion joining the not-staggered end part 17, 18 by a shoulder 21 extending substantially axially.
  • the described shape of the sides 15, 16 with end parts 17, 18 extending in circumferential direction shows the important advantage that during coupling during which a relatively high force is exerted on the faces 15, 16 caused by the contact elements of the connector parts 1, 2 sliding one into the other, the end parts 17, 18 remain unloaded so that wear of these parts and in particular of the shoulders 21 will not occur.
  • the force maintaining the connector assembly in the coupled position is distributed along a relatively large surface whereby the ribs 5 and the lugs 11 resist this force well.
  • lug 13 of each group of lugs 11-13 determines a stop edge 22 for the locking element 5 of a previous group of lugs 11-13 so that the ring 3 cannot be further rotated after reaching the end position.
  • bayonet spring ring 7 also has the usual function to maintain the couple length
