Definitions

  • the invention relates to a crimp contact for printed circuit boards according to the preamble of claim 1.
  • Such a crimp contact is already known from the AMP soldering aid contact shown in FIG. 3, in which the connection area of the base part and its clamping area are arranged at the same point. Due to this construction, it is necessary that the stranded wires to be connected are attached before soldering and attaching the crimp contact to the circuit board on the crimp connection, because afterwards the clamping area of the base part for the crimping process can no longer be placed alone between the anvil and the punch of the crimping tool. but at most the circuit board together with the crimp contact soldered and attached to it. However, this would damage or destroy at least the solder joint, possibly even the circuit board and components attached to it.
  • solder frames with additional devices for receiving the stranded conductors are to be provided. In the case of longer lines in particular, this effort is considerable due to the required reeling and fixing devices.
  • the stranded conductors are exposed to the process heat during preheating and during the soldering process in the wave soldering system, which can result in damage or even destruction of the insulating sheaths.
  • the invention is therefore based on the object of a crimp contact at the beginning to further develop the type mentioned in the simplest and cheapest possible way, that the effort on the wave soldering device and the risk of damage the stranded conductor insulation are avoided.
  • the clamping area can be arranged at a distance from the circuit board such that it is freely accessible to the crimping tool even after the connection part has been soldered onto the circuit board. So it is no longer necessary. crimping the stranded conductors before the soldering process, with the result that no special expenditure for holding and / or reeling devices on the soldering frame of the wave soldering device is necessary and damage to the insulation of the connecting lines due to the process heat during soldering is excluded. By eliminating the need for cable receptacles, the soldering frames can also be kept small, as a result of which a higher production throughput is achieved.
  • the attachment according to claim 2 is particularly favorable because it requires a minimum number of bending processes of the crimp contact, which is preferably produced as a cheap one-piece stamped and bent part, and, furthermore, the space required for storage and transport is small and the handling of this part is extremely simple, especially in the case of automated crimping.
  • the crimp contact in the edge region of the circuit board. This makes it possible to bend the clamping area either upwards or downwards according to the needs of the individual case without any additional effort. This is easily possible even after the crimp contact has been fastened and soldered to the printed circuit board, the crimping of the stranded conductor being able to take place before the crimp contact is angled, and thus enables a particularly simple circuit board assembly.
  • the crimp contact on the circuit board can also be arranged on the outside to such an extent that the bending edge is spaced from the circuit board edge, provided there is sufficient space for such a structure.
  • the crimp contact designed according to claim 6 such that the connection and the clamping area adjoin each other and each to one end of the base part range, the shortest possible length of the crimp contact is achieved therefore particularly suitable for use on small circuit boards.
  • the connecting part penetrating at least one recess in the printed circuit board has the task of fastening the crimp contact to the printed circuit board in addition to being fixed by the soldered joint in such a way that the soldered joint, even when strong tensile forces are exerted on the stranded conductor not mechanically stressed and thus a functional impairment (cold solder joint) or even the destruction of the solder joint can be effectively avoided in a simple manner.
  • this purpose is only reliably achieved if the contact parts of the connecting part, which are designed as tabs, are folded over by hand or by machine on the soldering side of the circuit board. This additional work step when assembling the circuit board with the crimp contact is omitted. if the connecting part is pressed into the associated recess in the printed circuit board (claim 7) or fastened in a latching manner (claim 8).
  • the elasticity is sufficient the printed circuit board, on the one hand the connecting part with protruding outwards To be able to put the latch through the recess and on the other hand a safe one Ensure that the circuit board engages behind the circuit board.
  • the necessary Relatively low manufacturing tolerances allow inexpensive manufacturing and an uncomplicated assembly.
  • an arrangement of the solder pads according to Claim 10 the advantage that a touch or at most before soldering a minimum distance between the parts to be connected by soldering, namely the Solder pads and the locking lugs exist, which makes an absolute without special measures secure solder connection in the wave soldering system is guaranteed.
  • the insulating part is expediently not on the crimping tool Attach sections of the base part.
  • the crimp contacts are manufactured using the stamping and bending process, the crimp contacts are first lined up in a band and then be isolated. In this case, by attaching the insulating web according to Claim 11 before separating a particularly simple manufacture of such crimp contact groups allows.
  • the crimp contact 1 consists of a flat base part 2 with a two vertically tabs 3 projecting therefrom, arranged in a connecting area 4 Connecting part 5 and one arranged in a clamping area 6. each a pair of clamping legs 7 for crimping and 8 for strain relief of a stranded conductor 9 having clamping part 10.
  • the connecting part 5 and the clamping part 10 are arranged one behind the other through a short section of the base part 2, the tabs 3 and the clamping legs 7, 8 projecting from the base part 2 in the same direction.
  • the crimp contact 1 with the tabs 3 of the connecting part 5 is first inserted into the slot-shaped recesses 13 of the printed circuit board 12 from the component side up to a stop edge 14 and by means of this on the soldering side engaging locking lugs 15 securely attached in a simple manner.
  • the recesses 13 are arranged such that the entire clamping area 6 projects beyond the edge area of the printed circuit board 12.
  • the assembled printed circuit board 12 is then placed in a soldering frame (not shown) introduced and soldered in a wave soldering system.
  • the solder joint 16 between associated solder pads of the circuit board 12 and the tabs 3 of the connecting part 5 takes place in the area of the locking lugs 15.
  • the stranded wires 11 of the stripped stranded conductor 9 are by means of a crimping tool by hand or machine crimped onto the clamping legs 7 and at the same time the stranded conductor 9 is relieved of strain with the help of the clamping legs 8.
  • soldering frame of the wave soldering device only take up the unit consisting of crimp contact 1 and printed circuit board 12. facilities for attaching or rolling up stranded conductors 11 can thus be omitted. In addition, the latter are not exposed to the process heat, so neither Thermal damage to the cable insulation can occur.
  • the described fastening of the crimp contact 1 by latching the tabs 3 is simple and nevertheless - even with strong tensile load on the stranded conductor 9 - safe guaranteed. This also protects the solder joint from the adverse effects of such forces, such as cold or even destroyed solder joints, effectively protected.
  • solder pads on the printed circuit board 12 for connection to the crimp contact 1 are adjacent arranged on the narrow end faces of the slot-shaped recesses 13. In this way there is a simple and secure solder connection between the soldering pads and the latching tabs 15 already attached to them before soldering reached.
