Definitions
- the invention relates to a contact spring arrangement, consisting of two oppositely arranged Contact springs each have a contact head, the one Contact surface and two side surfaces as well as one of the Has contact surface opposite surface, the the two contact surfaces face each other.
- the US-PS 4,660,922 shows a press fit pin in which the Contact area is cylindrical.
- the contact head (head) serves to do this, the pin, which is part of a power strip, firmly in anchoring part 46 ( Figure 5A).
- This component has a convex surface and side surfaces. The Problem with the scoring caused by a die cut eliminating a contact surface is not solved.
- the DE-GM 66 09 552 shows manufactured by stamping Recesses. However, they are not used to improve Contact surface, but for anchoring the pin in a Bracket washer (see p. 5, line 10).
- the object of the invention is a contact spring arrangement of the type mentioned above and a process for their To create manufacturing, the contact area improved shall be.
- the task is in a contact spring arrangement mentioned type according to the invention by the features of Claim 1 and by a method with the features of Claim 6 solved.
- Figure 1 shows a contact spring assembly 20 with two Contact springs 21 and 22.
- This contact spring arrangement is in a bore 23 of a plastic plate 24 (printed circuit board) used and on her over the plastic plate 24th projecting end provided with a contact pin 25.
- a so-called press-fit contact i.e. a contact that is elastic (not shown) Compressible area with which he in the Drilling another plastic plate (printed circuit board) is held.
- the contact springs 21, 22 each have contact heads 2, 2 ' on.
- a pin is now used to make a contact (not shown) from above (in Figure 1) between the two Contact heads 2, 2 'inserted through the Insertion opening 26.
- FIG. 3 shows the blank 10 punched out of sheet metal of a contact spring with side faces 15 and a contact face 14.
- the width b 0 of a contact head 2 is equal to the thickness of the sheet from which the contact springs 21, 22 are punched out.
- the punched blank as can be seen in FIG. 3, has cutting grooves 16 which result from the punching process which takes place in the S direction. This is how the contact springs look according to the state of the art in question here. If a plug element (not shown) is inserted between two contact springs 21, 22 with their contact surfaces 14, it can be seen that the grooves 16 act practically like a file on the contact surface of the plug element.
- the contact surface 14 provided with the cutting grooves 16 and created by the cutting process does not provide good electrical contact.
- the width b 0 of the contact surface is limited to the thickness of the sheet from which the contact spring was punched out.
- such a contact spring is processed further in that, as can be seen in FIG. 5, 15 recesses 7 are embossed in the embossing direction P in the two side surfaces.
- the material displaced by this embossing process causes the contact surface 14 to flow.
- the contact spring is smoothed in the embossing mold, so that the cutting grooves 16, which result from the previous punching process, largely disappear.
- the contact surface 4 of the finished contact head 2 or 2 ' is created.
- the contact surface also flows in width, of course only on the condition that the embossing shape is designed accordingly.
- the contact surface 4 then has a width b 1 which is greater than the original width b 0 of the blank 10 not provided with the embossed recesses 7. At the same time, this also results in a convex shape transversely to the longitudinal direction A of the contact spring, again provided that the embossing shape is designed accordingly (see FIG. 7). This creates the spoon-shaped contact surface 4, smoothed by the embossing process, which also makes good electrical contact.
- the recesses 7 can be stamped so far be that they merge, i.e. so how through the dashed lines indicated in Figure 7, a continuous recess 7 'arises.
- Recesses 17 are stamped and formed so that they are Surface 6, which is opposite the contact surface 4, are open.
