Definitions

  • the present invention relates to a contact socket.
  • a contact socket having an engagement sleeve enclosing, in a chamber-like manner, a contact spring, where the contact spring includes at least one spring leg, characterized in that the contact spring is supported via at least one lateral support spring, whereby the support spring is formed integrally on the contact spring.
  • the contact socket which is formed in two parts, comprises an engagement sleeve and a contact spring which is enclosed in a chamber-like manner by the engagement sleeve.
  • the two-part construction allows the material for the engagement sleeve and the contact spring to be separately provided and worked.
  • the manufacturing process and materials can be optimized and adapted to the individual component.
  • FIGS 1 and 2 there is shown a contact socket according to the invention, in accordance with a first embodiment, where, in a lateral cross-sectional view, the chamber-like closing of contact spring 2 by an engagement sleeve 1 can be easily recognized.
  • two support springs 3 are each formed on the contact spring 2 in the lateral region, approximately between a front contact location 4 and a rear holding section 5, to support the two free ends of the contact spring 2 and situated opposite to the contact locations 4.
  • each support spring 3 is shown as being essentially U-shaped, whereby a very wide base 11 is foreseen.
  • Each base 11 extends substantially parallel to contact spring 2 and is attached thereto by two short connecting legs which extend from the end of base 11 in the direction of contact spring 2.
  • the contact spring 2 is formed with a substantially square cross-section and is completely enclosed by the generally square engagement sleeve 1 in both the contact region and in the support region.
  • the layout of the engagement sleeve 1 comprises a latching tongue 8 which, during bending of the engagement sleeve 1, while protruding outwardly, is bent upwards in order to allow an anchorage of the engagement sleeve 1 in a receiving chamber (not shown) of a plug.
  • a projection 10 is foreseen which is bent away from the engagement sleeve 1, approximately at a right angle, as can be seen from Figure 2, in order to form a polarization of the contact socket.
  • the contours of the layouts of the engagement sleeves 1 and contact springs 2 are preferably stamped out of flat metal sheets as shown in Figures 3 and 4. After the stamping operation, the individual engagement sleeves 1 and contact springs 2 are separated and bent. The contact spring 2 is first bent into shape and the pre-bent or pre-folded engagement sleeve 1 is subsequently bent around the contact spring 2 such that the state as shown in Figures 1 and 2 is finally created.
  • the engagement sleeve 1 and/or the contact spring 2 are preferably laser soldered such that a solder pad 9 (from the top direction of the tool) is formed on several locations.
  • the two alternative designs (a) and (b) according to Figure 4 differ mainly by the size of the recess 6 or 7 on the contact spring 2, whereby the flexural strength of the spring leg 12 is increased by means of a smaller recess 7.
  • the spring leg 12 is guided away from the inner wall of the engagement sleeve 1 relatively far back, in the direction of the holding section 5 (or terminal section), whereby an improved spring action of the spring leg 12 can be achieved.
  • the required support of the spring legs 12 is obtained through support springs 3.
  • Figures 5 to 8 show a second embodiment of the present contact socket.
  • the effect and function obtained correspond to the first embodiment.
  • the lateral support springs 3 on each side are formed as single springs, as can be seen from Figure 5 and 6.
  • the advantage obtained in this way is simpler stamping and bending operations.
  • Figures 5 and 6 show the contact socket according to the invention in accordance with the second embodiment, whereby a lateral cross-sectional view of the chamber-like enclosure of a contact spring 2 by an engagement sleeve 1 is shown here.
  • one support spring 2 per side is formed on the contact spring 4 in the lateral region, approximately between a front contact location 4 and a rear holding section 5, to support the two free ends (spring legs 12) of contact spring 2 having opposite contact locations 4.
  • each support spring 3 is shown as being essentially U-shaped, where a very wide base 11 is foreseen, which extends substantially parallel to contact spring 2, as well as one short connecting leg each at the front end (left in Figure 5) which extends from the front end of base 11 in the direction of contact spring 2. In the rear section of base 11 the support spring 3 extends into the holding section 5.
  • the contact spring 2 is formed with a substantially square cross-section and is completely enclosed by the equally generally square engagement sleeve 1 in the contact region and in the support region.
  • the attaching point for the lateral support springs 3 on the contact spring 2 lies between contact location 4 and the holding section 5, such that a maximum spring displacement is maintained and the non-supported part of the spring legs 12 of contact spring 2 is not quite yet overloaded by the contact force (of an inserted contact pin which is not shown).
  • This construction has the advantage that a maximum spring displacement is obtained while providing an optimum support of the spring legs 12 by the support springs 3.
  • Figures 7 and 8 show the layout of the engagement sleeve 1 and the contact spring 2. These representations are not to scale.
  • the layout of the engagement sleeve 1 comprises a latching tongue 8 which, during bending of the engagement sleeve 1, while protruding outwardly, is bent upwards in order to allow an anchorage of the engagement sleeve 1 in a receiving chamber (not shown) of a plug.
  • a projection 10 is foreseen which is bent away from the engagement sleeve 1 approximately at a right angle, as is shown in Figure 2, in order to form a polarization of the contact socket.
  • the contours of the layouts of the engagement sleeves 1 and contact springs 2 are preferably stamped out of flat metal sheet, as shown in Figures 7 and 8. After the stamping operation, the individual engagement sleeves 1 and contact springs 2 are separated and bent. The contact spring 2 is first bent into shape and then the pre-bent or pre-folded engagement sleeve 1 is subsequently bent around the contact spring 2 such that the state as shown in Figures 5 and 6 is finally created.
  • the engagement sleeve 1 and/or the contact spring 2 are preferably laser soldered such that a solder pad 9 (from the top direction of the tool) is formed on several locations.
  • the construction of the contact socket according to the invention in particular through a cooperation of spring leg 12 and support spring 3 on the contact spring 2, allows the spring leg 12 to be guided away from the inner wall of the engagement sleeve 1 relatively far back, in the direction of the holding section 5 (or terminal section), whereby an improved spring action of the spring leg 12 can be achieved.
  • the required support of the spring legs 12 is obtained through support springs 3.
  • spring steel material such as X12CrNi
  • contact spring a copper beryllium spring or a steel spring provided with a precious metal plating is used.
  • the contact socket according to the invention which is formed in two parts, comprises an engagement sleeve 1 and a contact spring 2 which is enclosed in a chamber-like manner by the engagement sleeve 1.
  • the two-part construction allows the material for the engagement sleeve 1 and the contact spring 2 to be separately provided and worked.
  • the manufacturing process can be optimized and adapted to the individual component.
  • the contact spring 2 is furthermore provided with a support spring 3 which results in a support between a contact location 4 of the contact spring 2 and a holding section 5 of the contact spring 2.
