Definitions

  • the invention relates to an electrical spring contact in a receptacle housing with the features of the preamble of claim 1.
  • a known contact spring (DE-U-91 06 775) with an inner and an over-spring in box form can be fixed in the chamber of a receiving housing by means of spreading lances arranged close to the plug-side end of the over-spring and projecting beyond the outer contour of the spring contact.
  • the locking lances are supported by taking their spreading positions in undercuts or perforations in the receiving housing.
  • the fixing of the spring contact by means of locking lances is also mechanically unstable and not secure. Furthermore, with this spring contact, it is difficult to bend the latching lances back to a possible spring contact removal.
  • the spread latching lances also require an increased contact spacing, which prevents miniaturization of spring contacts.
  • the object of the invention is to provide a spring contact which is simple in its structure and handling and suitable for secure and stable fixability in the receiving housing.
  • the spring contact for removing the contact should be easy to unlock and free of damage.
  • the over-spring has a protective function for the contact spring arms in addition to the contact-strengthening effect due to its box-shaped design, and provides the prerequisite for stable fixing of the spring contact in the receiving housing.
  • the selected support further reduces the contact spacing, which is helpful for the miniaturization efforts with spring contacts.
  • the pivoting mobility of the spring-over sections allows a simplified and damage-free assembly and disassembly of the spring contact, the robust design of the spring contact permitting the application of greater disassembly forces.
  • the design of the spring contact provides the prerequisites at lower tool costs and an increase in tool life.
  • the bending slot is wedge-shaped with an increasingly larger width towards the free end of the spring-over spring. It is understood that the requirements for swiveling over spring sections can also be achieved in any other way.
  • the bending slot e.g. Executed over its entire length with substantially the same width and the opposing boundary surfaces (cut edges) of the bending slot be chamfered at least over a partial length. The chamfering of the boundary surfaces allows a more or less wide sliding of edge surfaces of the bending slot or the boundary surfaces of the spring-over sections towards one another when the spring-over sections are pivoted to one another.
  • the side surface opposite the bending slit having a side surface may have a slit which extends at least over a partial length from the free end in the direction of the spring-arm base, and which has diverging surfaces with increasingly greater width due to parallel chamfered or wedge-shaped towards the free end of the spring is limited.
  • the boundary surfaces of the constrictions, which are approached towards the free end, on projections or projections or the like protruding into the housing and projecting into the chamber. support, the approaches, projections or the like. any over Can extend sections or over the entire width of the chamber. It is understood that the approaches, projections or the like. optionally formed in the central region of the width of the chamber or arranged laterally offset in it.
  • the chamber approaches, projections or the like. be provided with bevels extending obliquely to one another in the insertion direction of the spring contact and the free end extending.
  • bevels extending obliquely to one another in the insertion direction of the spring contact and the free end extending.
  • the side surfaces which have the bending slot and / or the slot can be of any desired design, for example flat. It has proven to be advantageous to bend at least one of the side surfaces of the spring overwards and to place a pretension serving as a holding force between the side surfaces and the chamber walls on the spring by supporting the deflection against a chamber wall. In this case, the bends of the side surfaces and the free end of the over-spring can optionally be made wider than the inside width of the chamber of the receiving housing, which ensures a permanent preload between the spring contact and the chamber walls.
  • the pretension advantageously holds the spring contact in a vibration-damping manner in the receptacle housing, which has a favorable effect on the frictional wear.
  • 1 to 3 and 14, 1 denotes a spring contact which, as can be seen in FIG. 16, a contact spring serving as an inner spring 2 with a U-shaped base 3 and contact spring arms 5, 6 arranged on the legs 4 of the base 3
  • the contact spring arms extend obliquely to one another towards the free end of the contact spring 1 and have sections 5 ', 6' which are bent outwards at the free end to run-in slopes.
  • the contact spring 2 can be erected from a flat sheet metal blank.
  • an excess spring 10 is applied, which has a box shape in the embodiment.
  • the over-spring 10 is pushed with its base 11 onto the base 3 of the contact spring 2 and on this by bent-in tabs 12 which are in recesses 13 of the contact spring base engage, locked.
  • Overspring arms 14, 14 ' are formed on the base 11, which extend essentially parallel to the contact spring arms 5, 6 and press against the contact spring arms 5, 6 to increase the contact pressure.
  • the spring 10 can also be erected from a flat sheet metal blank.
  • constrictions 16 are provided which form support surfaces 17 at the end which is approached to the free end. By means of these support surfaces 17, the spring contact, as can be seen in FIGS.
  • the spring contact 1 is prevented from inadvertently sliding out of the chamber 18 by the chamber 21 at the plug-in end, which partially overlaps the insertion slots 29 for a knife contact (not shown).
  • the spring 10 carries bent guide elements 22 for knife contacts.
  • the bending slot 23 formed in a side surface 15 is formed in the embodiment of the spring contact of FIGS. 1 to 3 towards the free end of the spring 10 with an increasingly larger width.
  • the bending slot 23 designed in this way allows the over-spring sections 10 ′, 10 ′′, which extend on both sides of the bending slot 23, to bend towards one another.
  • the bending slot 23 is delimited by parallel surfaces 24, which are designed as smooth phases in order to achieve the possibility of swiveling the spring-over sections 10 ′, 10 ′′.
  • the surfaces 24 allow the over-spring sections 10 ′, 10 ′′ to pass to one another to a greater or lesser extent.
  • the spring contact 1 is provided in the side surface 15 opposite the wedge-shaped bending slot 23 with the side surface 15 having a slit 26 which extends over a partial length of the side surface 15 and the pivoting-down processes of the spring-over sections 10 ', 10' 'helps ease.
  • the slit 26 can be designed as desired, for example as shown in FIGS. 9 and 13, or is wedge-shaped or trapezoidal.
  • FIG. 6 shows a spring contact 1
  • the side surfaces 15 of the spring 10 shown by dash-dotted lines 27 are bent outwards.
  • the bent-out side surfaces 27 practice when the spring contact 1 is introduced into the chamber 18 of the receiving housing 19
  • Fig. 8 shows a frictional force between the side surfaces 27 and the walls of the chamber 18, by the influence of which a vibration-free mounting of the spring contact 1 in the chamber 18 is ensured.
  • the chamber 18 of a receiving housing 30 is overlapped at its free end by a cover part 28 which can be snapped on at 34 and which has an insertion opening 29 for a knife contact (not shown). Furthermore, the receptacle housing 30 has a locking body 31 which engages behind the spring 10 and is held in the locking position shown by a locking member 32 arranged on the cover part 28.
  • the locking body 31 is first pivoted outwards and, after having been overrun by the spring 10, automatically returned to the position shown.
