Definitions

  • the present invention relates to a contact socket.
  • the contact socket which is of a single-part construction, comprises a base spring and two internal spring legs, the contacting sections of which essentially face each other.
  • the single-part construction allows the optimization of the manufacturing process which then essentially consists only of a bending operation and/or pressing operation.
  • a further advantage of the contact socket according to the invention is that the resilient force on each spring leg can be relatively easily increased by providing a support member which is also integrally formed on the base spring and on which the spring leg is then supported.
  • the resilient force can hereby be significantly increased.
  • Figures 1 and 3 of a first preferred embodiment show a contact socket according to the invention in a lateral cross-sectional view.
  • a base spring 1 is shown having two spring legs 12, which essentially face each other with their contact sections 4 on the inside of the base spring 1.
  • an external latching tongue 8 is formed on the base spring 1 (shown on top in Figures 1 and 2).
  • the spring legs 12 lie inside base spring 1.
  • a facing second (lower) spring leg 12 is foreseen on the base spring 1 opposite the first (upper) spring leg 12 such that the contact sections 4 of spring legs 12 face each other in the plug-in direction, in the left half of base spring 1. It can furthermore be clearly seen from Figures 1 and 2 that spring legs 12 are accommodated inside the base spring 1.
  • the latching tongue 8 protrudes upwards at an acute angle of approximately 5° to 10° beyond the base spring 1. Both spring legs 12 form resilient contacting metal pieces which conduct the current directly and therefore conduct it more efficiently.
  • FIG 3 shows the layout of base spring 1. This view is not to scale.
  • the layout of base spring 1 with integral spring legs 12 has a compact form with reduced loss of sheet metal during stamping.
  • Base spring 1 further comprises a projection 10 which is bent from the base spring 1 approximately at a right angle, as shown in Figure 2, in order to form a polarisation of the contact socket.
  • the contours of the layout of base springs 1 are preferably stamped out of flat metal sheets, or possibly also cut by means of a laser, as shown in Figure 3. After the stamping operation the individual base springs 1 are separated and are each bent and/or pressed until finally the state as shown in Figures 1 and 2 is obtained.
  • the base spring 1 can preferably be soldered by means of a laser, such that at least one solder pad is placed on one location in the tool from above in order to fix the base spring 1.
  • both spring legs 12 are each supported by a support member 3.
  • This support member 3 is formed by means of a free punch 5 (see Figure 2) and is connected to base spring 1 by means of a base 11.
  • Each support member has an essentially U-shaped configuration whereby a base section of the U-shape creates a connection between the base 11 and the other end of support member 3.
  • the chamfered connection between support member 3 and the corresponding spring leg 12 is formed in the vicinity of contacting section 4 such that each spring leg 12 with the surrounding base spring 1 forms a gap which opens in the direction of the insertion opening of the contact socket.
  • they are each supported by support member 3.
  • tabs 7 are formed on both sides of an insertion opening (of base spring 1) for a contact pin (not shown), which tabs show outwardly rounded contours and facilitate the insertion of the contact pin.
  • the tabs 7 also serve, as can be seen from Figure 2, to prevent an insertion behind spring leg 12.
  • Figure 4 schematically shows two possible folds a) and b) of the contact socket according to the invention.
  • Alternative (a) shows a helically wound or folded contact socket, while alternative (b), with a blank that is rotated by 180° for the contacts, shows a fold which follows the contours of a square, whereby each side is covered twice.
  • FIGs 5 to 7 show a contact socket according to the invention, in accordance with a second preferred embodiment, whereby here in a lateral cross-sectional view according to Figure5 a base spring 1 is also shown, on which two spring legs 12 are foreseen, which essentially face each other with their contact sections 4 on the inside of the base spring 1.
  • an external latching tongue 8 is formed on the base spring 1 (shown on top in Figures 5 and 6).
  • the spring legs 12 lie inside base spring 1.
  • a facing second (lower) spring leg 12 is foreseen on the base spring 1 opposite the first (upper) spring leg 12 such that the contact sections 4 of spring legs 12 face each other in the plug-in direction, in the left half of base spring 1. It can also be seen from Figures 5 and 6 that spring legs 12 are completely accommodated inside the base spring 1.
  • the latching tongue 8 protrudes upwards at an acute angle of approximately 10° beyond the base spring 1. Both spring legs 12 form resilient contacting metal pieces which conduct the current directly and therefore conduct it more efficiently.
  • Figure 7 shows the layout of base spring 1. This view is not to scale.
  • the layout of base spring 1 with integral spring legs 12 has an extremely compact form with reduced loss of sheet metal during stamping.
  • the connection of spring legs 12 and the corresponding support member 3 (which will be described later) takes place in this embodiment on the left frontal side of base spring 1.
  • On the base spring 1 a projection 10 is additionally foreseen which is bent approximately at a right angle from base spring 1, as shown in Figure 2, to form a polarisation of the contact socket.
  • the contours of the layout of base springs 1 are preferably stamped out of flat metal sheets or, possibly, also cut by means of a laser, as shown in Figure 7.
  • a separation cut takes place at position X, in order to form the two spring legs 12 such that they can move away from each other, namely for the case when the contact pin is later inserted.
  • the individual base springs 1 are separated and are each bent and/or pressed until finally the state as shown in Fig 5 and 6 is obtained.
  • the base spring 1 can preferably be soldered by means of a laser, such that at least one solder pad is placed on one location in the tool from above in order to fix the base spring 1.
  • the construction of the present contact socket according to the invention allows creation of the relatively high resilient force whereby an improved spring action of the spring components can be achieved.
  • both spring legs 12 are each also supported by a support member 3.
  • This support member 3 is formed by means of a free punch 5 (see Figure 7) and is connected to base spring 1.
  • Each support member has an essentially U-shaped configuration whereby a longitudinal base section of the U-shape creates a connection between base 11 and the other end of support member 3.
  • the chamfered connection between support member 3 and the corresponding spring leg 12 is formed in the vicinity of contacting section 4 such that each spring leg 12 with surrounding base spring 1 forms a gap which opens in the direction of the insertion opening of the contact socket.
  • they are each supported by support member 3.
  • tabs 7 are formed on both sides of an insertion opening (of base spring 1) for a contact pin (not shown), which tabs show outwardly rounded contours and facilitate the insertion of the contact pin.
  • the tabs 7 also serve, as can be seen from Figure 5, to prevent an insertion behind spring leg 12.
  • FIGs 8 and 11 show a contact socket according to the invention, in accordance with a third preferred embodiment, whereby here in a lateral cross-sectional view according to Figure 8 a base spring 1 is also shown, on which two spring legs 12 are foreseen, which essentially face each other with their contact sections 4 on the inside of the base spring.
  • an external latching tongue 8 is formed on the base spring 1 (shown on top in Figures 8 and 9).
  • the spring legs 12 lie inside base spring 1.
  • a facing second (lower) spring leg 12 is foreseen on the base spring 1 opposite the first (upper) spring leg 12 such that the contact sections 4 of spring legs 12 face each other in the plug-in direction, in the left half of base spring 1. It can be seen from Figures 8 and 9 that spring legs 12 are completely accommodated inside the base spring 1.
  • the latching tongue 8 protrudes upwards at an acute angle of approximately 10° beyond the base spring 1. Both spring legs 12 form resilient contacting metal pieces which conduct the current directly and therefore conduct it more efficiently.
  • FIG 11 shows the layout of base spring 1. This view is not to scale.
  • the layout of base spring 1 with integral spring legs 12 has an extremely compact form with reduced loss of sheet metal during stamping.
  • the connection of the spring legs 12 and the corresponding support member 3 (which will be described later) takes place in this embodiment on the left frontal side of base spring 1.
  • Base spring 1 further comprises a projection 10 which is bent from the base spring 1 approximately at a right angle, as shown in Figure 9, in order to form a polarisation of the contact socket.
  • base springs 1 are preferably stamped out of flat metal sheets or, possibly, also cut by means of a laser, as shown in Figure 11.
  • a separation cut takes place at the four positions X, in order to form the two spring legs 12 such that they can move away from each other, namely for the case when the contact pin is later inserted.
  • the individual base springs 1 are separated and are each bent and/or pressed until finally the state as shown in Figures 8 and 9 is obtained.
  • the base spring 1 can preferably be soldered by means of a laser, such that at least one solder pad is placed on one location in the tool from above in order to fix the base spring 1.
  • the construction of the present contact socket according to the invention in particular through the cooperation of both spring legs 12, allows creation of the relatively high resilient force whereby an improved spring action of the spring components can be achieved.
  • both spring legs 12 are also supported each on both sides by two support members 3.
  • the support members 3 are formed by means of a free punch 5 (see Figure 11) and are connected to the base spring 1.
  • Each support member 3 has an essentially U-shaped configuration whereby a longitudinal base section of the U-shape creates a connection between base 11 and the other end of support member 3.
  • the chamfered ends of each support member 3 are formed without a direct connection to the spring leg 12.
  • each spring leg 12 is mounted in a seesaw manner in the middle of support member 3 and connected to support member 3.
  • the fulcrum 13 is formed on the spring leg 12 approximately in the middle between support member 3 and spring leg 12.
  • tabs 7 are formed on both sides of an insertion opening (of base spring 1) for a contact pin (not shown), which tabs show outwardly rounded contours and facilitate the insertion of the contact pin.
  • the tabs 7 also serve, as can be seen from Figure 8, to prevent an insertion behind the lower spring leg 12.
  • the contact socket according to the invention which is of a single-part construction, comprises a base spring 1 and two spring legs 2 which are integrally formed on the base sleeve 1. Both spring legs 12 comprise contacting sections 4, essentially facing each other. As a result of the single-piece construction the manufacturing process of this contact socket can be optimized. Furthermore, each spring legs 12 is supported by an additional support member 3 thereby increasing the resilient force of spring leg 12.
