Definitions

  • the invention relates to a connector housing which is divided into two housing parts which are longitudinally divided in the plugging direction and which are held together by means of a fastening device.
  • Connectors with such connector housings are used in particular as interface connectors for computers.
  • the two connectors to be connected are each on a housing wall of two devices to be connected. In this case, the two connectors are held together by the two devices.
  • a connector that closes a cable is attached to a mating connector or a device wall by means of fastening elements. This can e.g. using bolts.
  • the fixing of the plug connector by means of the fastening elements is intended on the one hand to prevent the plug connector from being released from its plug connection, and on the other hand to bring about a mechanical relief for the plug contacts of the plug connector.
  • the two housing parts are either screwed together or held together by means of locking fingers.
  • locking fingers are sometimes small and delicate elements that do not have a particularly high holding force and can easily break off.
  • fastening elements for fastening the connector housing to a mating connector or a device wall.
  • a connector housing is made available which enables a simple assembly process for joining the two housing parts to form the connector housing, including positioning of the fastening elements which may be required, such as screw bolts, and in which the risk of failure of locking fingers holding the housing parts together is eliminated and the risk of being lost the fasteners required such as bolts are greatly reduced.
  • a connector housing of the type specified at the outset is characterized in that the fastening device is formed by at least one spring clamp which can be snapped onto one of the two opposite long sides of the connector housing and overlapped on the housing parts placed against one another.
  • each spring clamp can be provided with a fastening element holder or a screw bolt holder, by means of which the respectively assigned fastening element or the respectively assigned screw bolt captively but movably is held on the spring clamp in such a way that it can be held in alignment with the associated fastener or screw receiving channel when the spring clamp is snapped onto the connector housing and can be brought into fastening or screw connection with the mating connector housing or the device wall.
  • the two housing parts can be held together on both long sides with a spring clamp.
  • a spring clamp only on one long side of the connector housing and of holding the two housing parts to one another on the other long side by means of a hinge.
  • the hinge can be formed by a film hinge.
  • each spring clamp is provided with a detent spring part on each of the two longitudinal edges, and the connector housing has a complementary detent recess or a complementary detent projection on the two longitudinal edges of both longitudinal sides.
  • the bolts are held either by locking the spring clamp are clamped with the connector housing between the spring clamp and the connector housing, or the spring clamps are each formed with a screw holder which holds the screw bolt on the spring clamp, regardless of whether the spring clamp is snapped onto the connector housing or not. The same applies to the use of fasteners other than screws.
  • each spring clamp is hinged to one of the two housing parts. This not only allows the two housing parts to be assembled in a particularly easy-to-handle manner to form the connector housing, but also ensures to a particularly high degree that all required parts are available. It is only necessary to hold the two housing parts together and to pivot the two spring clamps into their respective snap or latched position.
  • fastening element or bolt holder is formed in one piece with the spring clamp, for example in the form of an eyelet knocked out and bent out of the material of the spring clamp.
  • the bolt receiving channels can either be closed when the housing parts are joined, the bolts and the bolt holders of the spring clamps being designed such that the bolts held in the bolt holders are not only rotatable for the purpose of screwing, but are also longitudinally displaceable for the purpose of insertion into the associated screw receiving channel.
  • fasteners other than bolts can either be closed when the housing parts are joined, the bolts and the bolt holders of the spring clamps being designed such that the bolts held in the bolt holders are not only rotatable for the purpose of screwing, but are also longitudinally displaceable for the purpose of insertion into the associated screw receiving channel. The same applies to fasteners other than bolts.
  • each screw receiving channel open towards the longitudinal outside of the connector housing, in such a way that the associated screw pin can be inserted into the screw receiving channel transversely to the direction of insertion.
  • the bolt is held in the bolt holder of its spring clamp in such a way that it is automatically inserted into the bolt receiving channel transversely to the direction of insertion when the spring clamp is snapped onto the housing parts placed against one another.
  • the bolt then only needs to have so much longitudinal mobility within the bolt holder that the screw path when tightening the bolt in the mating connector or the device wall is possible. The same applies to fasteners other than bolts.
  • both housing parts on the one hand and both spring clamps on the other hand are of identical design. Then only the same housing parts and spring clamps need to be kept in stock and you no longer have to take care that an equal number of pieces is available from each of the two housing parts. As long as there is only an even number of such housing parts with spring clamps, they can be assembled into connector housings.
  • Fig. 1 it is shown how a unit from a connector housing (11), two spring clamps (13) (of which only one can be seen) and two bolts (15) (of which only one can also be seen) is assembled.
  • a screw bolt 15 is shown in side view, which has a bolt head 17 with a rotary slot 19 for cooperation with a screwdriver. At the end opposite the pivot pin 17, the screw pin 15 is provided with a screw thread 21. A collar 23 is located between the bolt head 17 and the screw thread 21.
  • a spring clamp 13 is shown in front view in FIG. 3 .
  • the spring clamp 13 has a hinge sleeve 25.
  • the spring clamp 13 is provided with a detent spring part 27 which is S-shaped in side view.
  • an eyelet-shaped screw pin holder 29 Between the hinge sleeve 25 and the detent spring part 27 there is an eyelet-shaped screw pin holder 29. This is knocked out of the flat material of the spring clamp 13 and bent out in an eyelet shape.
  • Fig. 4 shows a side view of a spring clamp 13 with a bolt 15 held thereon.
  • the bolt 15 To mount the bolt 15 on the spring clamp 13, one can proceed in such a way that the eyelet of the bolt holder 29 is placed around the bolt 13 after the bolt 15 has been placed on the spring clamp 13 15 bent around or that you first only bend the eyelet with a diameter such that the collar 23 of the bolt 15 fits through, and then the eyelet is bent so far that on the one hand mobility of the bolt 15 within the eyelet is possible, but on the other hand the collar 23 and the bolt head 17 do not fit through the eyelet. As a result, the screw bolt 15 is held captively on the spring clamp 13.
  • FIG. 5 shows a connector housing 11, which consists of an upper housing part 31 and a lower housing part 33 in this partial view.
  • both housing parts are identical, so that only one injection mold and the storage of only one housing part are required for the production of the connector housing 11.
  • Each of the two housing parts 31, 33 has on one longitudinal side a longitudinal recess 35 running in the longitudinal direction of the housing, over which extends a hinge shaft 37 which, together with the hinge sleeve 25 of the spring clamp 13, forms a pivot hinge.
  • each housing part On the longitudinal side opposite the longitudinal recess 35, each housing part has two latching projections 39 which cooperate with the S-shaped latching spring part 27 of the spring clamp 13 to form a latching or snap connection.
  • the connector housing 11 has on both sides a screw-receiving projection 41 projecting transversely to the longitudinal axis of the housing.
  • each screw-receiving projection 41 is penetrated by a screw-receiving channel 45 running in the longitudinal direction of the housing.
  • FIG. 1 shows a fully assembled connector housing 11 with spring clamps 13 and screw bolts 15, although only one spring clamp 13 and one screw bolt 15 can be seen.
  • the spring clamp 13 shown is in the open position.
  • Fig. 6 shows an embodiment of the invention, in which the two housing parts 31 and 33 are held together by two spring clamps 47, each having a detent spring part 49 at both longitudinal ends.
  • the housing parts 31 and 33 are each provided on their longitudinal side edges with a latching groove 51, into which the spring clamps 47 can snap or be inserted.
  • an insertion of the locking spring parts 49 into the locking grooves 51 is indicated. This means that the spring clamps are pushed onto the connector housing from the rear.
  • the screw bolts are not shown in FIG. 6 . These are either clamped between the connector housing 11 and the spring clamps 47 or they are held captively on the spring clamps 47 by means of screw bolt holders 29 (only shown for the right spring clamp in FIG. 6 ).
  • 7 shows an enlarged end view of a spring clamp 47 with a bolt holder.
