Definitions

  • the present invention relates to a connector according to the preamble of claim 1 as e.g. is known from DE-A-3 042 293.
  • the present invention relates to a connector with a housing that can be attached to the front panel of a device, in which a contact insert that can be inserted into the housing can be removed from the housing in the direction of the inside of the device.
  • the contact insert of such plug connectors which can have the shape of a contact socket, is often designed as a so-called filter plug, which has socket-shaped contact pins on one side and solder pins on the opposite side.
  • the filter itself is mostly integrated in the contact insert.
  • the socket housing is screwed onto the front plate from the outside.
  • the socket housing has to be unscrewed or the contact insert has to be drawn out in a cumbersome manner on the front of the front plate, which also has the consequence that the cables connected to the contact insert are pulled out of the device through the front panel. If the new cables to be connected to the contact insert are inside the device, it is extremely cumbersome to pull them through the narrow opening in the front panel to the outside of the device.
  • a snap element was provided in a known contact socket, which engages in a circumferential groove arranged on the inside of the socket housing in the state of the contact insert inserted in the socket housing.
  • the contact insert is inserted from the inside of the front panel.
  • the elastic snap element By plugging a tube on the contact insert from the outside of the front panel, the elastic snap element can be bent back so that it is pressed out of the circumferential groove, whereby the contact insert can be pushed into the interior of the device from the outside.
  • the connections can therefore be changed on the contact insert, whereupon the contact insert is pushed into the housing from the inside until the elastic snap element springs into the circumferential groove.
  • the present invention has for its object to develop a connector of the type mentioned so that with easy removal of the contact insert from the housing of the connector, a secure guidance of the contact insert is guaranteed within the housing.
  • an axially displaceable intermediate ring lying in the insertion direction of the contact insert behind the snap element is arranged in the circumferential groove of the housing, that the intermediate ring can be pushed over the snap element and that the intermediate ring and the snap element are designed such that the Snap element in the position of the intermediate ring, in which it is pushed over the snap element, is offset in relation to its original position in the radial direction of the connector.
  • the end of the intermediate ring facing away from the snap ring is designed to project radially inwards with its inner diameter relative to the adjacent groove edge of the circumferential groove.
  • the inwardly projecting end of the intermediate ring offers in a particularly simple manner the second contact surface seen in the longitudinal direction of the contact insert within the circumferential groove.
  • This contact surface is from which the connections or solder pins bearing end of the contact insert further away than the snap ring itself, so that the tilt play of the contact insert in the socket housing is greatly reduced.
  • the snap element can advantageously be designed as a conical snap ring which widens against the insertion direction of the contact insert and which cooperates with a hollow cylindrical intermediate ring. It is also possible for the intermediate ring to have a suitable conicity on its inside, which forces a likewise conical or cylindrical ring-shaped snap element to engage inwards in the radial direction.
  • the snap element designed as a snap ring is pressed radially inward by the intermediate ring, so that it is pressed out of the circumferential groove, whereupon the contact insert can be pushed into the interior of the housing.
  • the intermediate ring In the installed state of the contact insert, the intermediate ring also has the effect that the contact insert, as seen in the longitudinal direction, can be supported at two points in the housing. This prevents the contact insert from tilting relative to the housing of the connector.
  • the end of the intermediate ring facing away from the snap ring can be formed so that it is bent radially inwards such that the outer diameter of the bent end is adapted to the inner diameter of the adjacent groove edge of the circumferential groove.
  • the intermediate ring assumes the correct position when inserting the contact insert and in its installed state is preferably achieved in a simple manner in that the groove base of the circumferential groove is designed to rise in the opposite direction to the insertion of the contact insert. This increase in the base of the groove is extremely small, just sufficient that the intermediate ring can be easily moved in the direction of insertion when the contact insert is inserted.
  • the compression of the snap ring with the aid of the intermediate ring can be further facilitated in that the radial inner surface of the intermediate ring is approximately beveled in accordance with the conicity of the snap ring. This ensures that the intermediate ring always engages the snap ring over a large area without wear occurring on the snap ring even when the contact insert is loosened several times.
  • the snap ring can be integrally connected to the contact insert in a contact insert made of plastic.
  • the snap ring can be molded on, for example, directly during the production of the contact insert if the base material of the contact insert is a has sufficient rigidity.
  • the basic structure of the connector designed as a contact socket according to FIGS. 1 and 4 is the same, so that the following description applies to both exemplary embodiments.
  • the same reference numerals are used for the same and similar components.
  • the contact socket 1 comprises a socket housing 3 which can be screwed onto the outside of a front plate 2 of a device (not shown) and a contact insert 4 which can be inserted into the socket housing 3.
  • the contact insert 4 as can still be seen better from FIG. 4, is designed as a filter plug or filter socket and has solder pins 5 on the right-hand side shown in the drawing, while it is provided with connection sockets 6 or connection plugs 7 on the opposite side .
  • the contact insert 4 can be inserted into the socket housing 3 from the right-hand side as seen in the drawing, that is to say the inside of the front plate 2 (see FIG. 3).
  • the contact insert 4 has an essentially conical, elastic snap element 8 that widens against the insertion direction A.
  • the snap element 8 consists of individual tongues which are penetrated by recesses in the circumferential direction.
  • the snap element 8 is designed as a circumferential snap ring.
  • the socket housing 3 is provided on its inside with a circumferential groove 9.
  • the circulation groove 9 is delimited towards the insertion side by a groove edge 10 and on the opposite side by a groove edge 11.
  • the snap element 8 rests on the right groove edge 10.
  • the contact sockets of both embodiments are cylindrical.
  • An axially displaceable intermediate ring 12 is arranged in the circumferential groove 9 of the socket housing 3 in the insertion direction A behind the snap ring or the snap element 8.
  • the intermediate ring 12 bears against the left groove edge 11.
  • the left groove edge is formed by a radial seal 13 which seals the socket housing 3 with respect to the contact insert 4.
  • the radial seal 13 is arranged behind the groove edge 11 as seen in the insertion direction A.
  • the groove edge 11 is part of the socket housing 3 here.
  • the inner diameter of the intermediate ring 12 at the end 14 facing the snap ring 8 is adapted to the inner diameter of the adjacent groove edge 10 of the circumferential groove 9.
  • the two diameters are essentially the same.
  • the outer diameter of the intermediate ring 12 corresponds approximately to the inner diameter of the circumferential groove 9 in the bottom of the groove and in such a way that the intermediate ring 12 is axially displaceable in the circumferential groove 9 with slight play.
  • the end 15 of the intermediate ring 12 facing away from the snap ring 8 is designed with its inside diameter to project radially inwards relative to the adjacent groove edge 11 of the circumferential groove 9. As can be seen both from FIG. 1 and from FIG. 4, the contact insert 4 bears against the end 15 of the intermediate ring, which is formed to protrude radially inwards.
  • the contact insert 4 is held in the axial direction at two locations, namely on the receptacle 17 and on the radially inwardly projecting end 15 of the intermediate ring 12. Due to the relatively large distance between the receptacle 17 and the end 15 of the intermediate ring 12, the contact insert 4 lies in the socket housing 3 with an extremely small tilting clearance.
  • the end 15 of the intermediate ring 12 facing away from the snap ring is bent radially inwards, in such a way that the outer diameter of the bent end 15 corresponds to the inner diameter of the adjacent groove 11 the circumferential groove is adapted.
  • the end 15 of the intermediate ring 12 is shifted further to the left, so that the distance between the receptacle 17 and the end 15 of the intermediate ring 12 is further increased.
  • the bottom of the circumferential groove 9 is designed to rise slightly opposite the insertion direction A of the contact insert 4. This is an extremely slight increase in the base of the groove, which means that when inserting the contact insert 4, the intermediate ring 12 is always carried up to the groove edge 11.
  • the radial inner surface of the intermediate ring 12 is approximately adapted to the conicity of the snap element 8 which widens outwards.
  • the snap element 8 is also integrally connected to the contact insert 4 made of plastic. Snap element 8 and Contact insert 4 can be injection molded in one operation.
  • the snap ring 8 is formed as an independent part, which is inserted in a groove 18 and protrudes from the groove 18 with its end opposite the insertion direction A.
  • the other end of the snap ring can be attached to the opposite edge of the groove, depending on the material, by thermal welding or gluing.
  • a tubular tool 20 consisting of a round tube is first inserted into the socket housing 3 from the outside of the front plate 2, so that the right end of the tubular tool 20 engages around the outer circumference of the contact insert 4.
  • the seal 13 is pressed so far that the pipe tool 20 fits between the seal 13 and the outer periphery of the contact insert 4.
  • the right end of the pipe tool 20 abuts the left end 15 of the intermediate ring 12.
  • the intermediate ring 12 is also shifted to the right, which has the result that the right end 14 of the Intermediate ring 12 between the bottom of the groove Circulation groove 9 and the outer circumference of the snap ring 8 pushes.
  • the snap ring 8 is pressed radially inward until the maximum outer diameter of the snap ring 8 is smaller than the minimum inner diameter of the groove 10 (see FIG. 2).
  • the contact insert can be pushed out of the socket housing 3, or better said, onto the inside of the front plate 2 by means of a pressure stamp 21 located in the pipe tool 20.
  • the contact insert 4 is in the interior of the device, not shown. After attaching further connections to the solder pins 5, the contact insert 4 is simply inserted in the reverse order into the socket housing 3 from the right. The pipe tool 20 is no longer required for this, since the snap ring 8 is automatically compressed by the groove edge 10. Because of the slightly sloping bottom of the circumferential groove 9 in the insertion direction A, the intermediate ring 12 can be moved particularly easily in the insertion direction A. This ensures that it is carried along the left groove edge 11 of the circulation groove when the contact insert 4 is inserted.
