Definitions

  • the present invention relates to a contact socket for receiving a tab or pin terminal.
  • a contact socket according to the preamble of claim 1 is disclosed in DE-A-196 19 514.
  • the known contact sockets have a complicated construction and are therefore difficult to manufacture. These known contact sockets are expensive to manufacture. It is therefore an object of the present invention to provide a contact socket allowing the design of a simpler manufacturing process and which thereby entails lower costs.
  • a contact socket having two internal spring legs formed on a base spring, contacting sections of the spring legs face each other, and one of the two spring legs is bent in a U-shaped configuration, while the other spring leg is bent linearly, extending slightly obliquely towards the interior of the base spring, characterized in that the linear spring leg is supported by a support member bent in a U-shape configuration.
  • the contact socket which is of a single-part construction, has a base spring (or a base part) and two internal spring legs, the contacting sections of which face each other.
  • the single-part construction allows the optimization of the manufacturing process which consists essentially of a bending operation and/or stamping operation.
  • a further advantage of the contact socket according to the invention is that the resilient force on one of the two spring legs can be relatively easily increased by a support member which is also formed integrally on the base spring, and on the free end thereof one of the spring legs is supported.
  • the resilient force can hereby be considerably increased.
  • Figures 1 and 2 show a contact socket according to the invention in accordance with a preferred embodiment, where a lateral cross-sectional view of a base spring 1 is shown, on which two spring legs 12 are seen, which 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.
  • spring legs 12 are completely accommodated inside the base spring 1.
  • the latching tongue 8 protrudes upwards at an acute angle of approximately 5° beyond the base spring 1.
  • the two spring legs 12 form a readily resilient contact metal piece by which current is directly, and therefore more efficiently, conducted.
  • Figure 3 shows the layout of the base spring 1. This view is not to scale.
  • the layout of the base spring 1 with integral spring legs 12 has a compact form resulting in reduced loss of sheet metal during stamping.
  • 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 cut by laser, as shown in Figure 3. After the stamping operation, the individual base springs 1 are separated and each bent and/or pressed, until the state shown in Figures 1 and 2 is established.
  • the base spring 1 can preferably be soldered by means of a laser, such that a solder pad is set on at least one location on the tool from the top in order to fix base spring 1.
  • the base spring 1 (or base part) can also be fixed by pressing; the projections 13 shown in Figure 3 come into engagement with apertures 14 and are then pressed such that in this manner the base spring 1 can be stabilised or fixed in its form.
  • the construction of the present contact socket according to the invention allows creation of the relatively high resilient force whereby improved spring action of the spring components can be achieved.
  • the one spring leg 12 is supported from one free end of a support member 3.
  • This support member 3 is formed as a further spring member by means of a free punch 5 and is connected to base 11 via a base spring 1. In order to further increase the resilient force of the lower spring leg 12 it is supported by support member 3.
  • the upper spring leg 12 is formed on the top edge of the base spring 1 by backward folding.
  • 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 to prevent an insertion behind the lower spring leg 12, since the lower spring leg 12 in its two lateral end sections 9 is prevented by tabs 7 from moving upwards.
  • the lower spring leg 12 cannot be further displaced upwardly than as shown in Figure 1. In this position of the lower spring leg 12 the lateral end sections 9 lie adjacent to the lower edge of tabs 7.
  • the tabs 7 thereby form a pre-aperture of spring legs 12.
  • the consumption of material is minimized since the loss of sheet metal during stamping is reduced. As is shown in the layout according to Figure 3, there is little stamping residue.
  • FIG 4 shows part of a bending operation of the contact socket according to the invention.
  • the lower spring leg 12 and the support member 3 are bent in five steps.
  • the contact socket is first stamped out.
  • the first bending step the lower spring leg 12 is then bent upwards, approximately at a right angle from the base plane (extending horizontally in Figure 4) in an upwardly protruding direction.
  • the support member 3 is then bent upwards and bent backwards as shown in the bending step 2 (with respect to the plug-in direction in the contact socket), into the free punch 5 of the lower spring leg 12.
  • the final position of support member 3 is shown in bending step 3.
  • the lower spring leg 12 is further bent forwards until it comes to lie on support member 3.
  • the position of the lower spring leg 12 is calibrated.
  • the contact socket according to the invention which is of a single-part construction, comprises a base spring 1 and two spring legs 12, which are integrally formed on base spring 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, one of the spring legs 12 is supported by an additional support member 3 thereby increasing the resilient force.
