Description

GERMAN

In telecommunications, especially telephone systems, is it is known to design the structural units carrying the electrical components so as to be pluggable, thereby a to enable easy replacement of these structural units in devices or racks. Particular difficulties occur in units that are provided with printed lines arranged on insulating panels are. Since, on the one hand, the size of the components to be fastened is small compared to previous ones, thus a much larger number of components in the same large structural units can be accommodated, but on the other hand this means more connection contact points are required, the previously known connector arrangements for printed lines can not can be used without further ado. You need a relatively large pitch at the contact points, which is mostly due to the formation of the counter springs fixed in the device or frame Connector is conditional.

The invention is based on the object of avoiding these disadvantages. This is achieved by that wire pins are used as a connector through holes in the edge zones of the insulating plate inserted through, fixed by bending or squeezing the wire ends on the insulating plate and are electrically conductively connected to the corresponding printed lines.

The advantage of the invention is primarily that the manufacture and attachment of the contact pins can be carried out by fully automatic machines. As mating contact springs too It is advisable to use cup springs for the contact pins, as is the case with miniature tubes, for example are known.

The invention is described below with reference to some of the exemplary embodiments shown in FIGS described in more detail. Show it

is done by dip soldering at the same time as the switching elements are soldered. Because of this, the Contact point 1 ″ of the wire is bent upwards against the dip solder point 1 '(FIG. 2) (in Fig. 3) and the slot 5 should enclose the wire 1 tightly. For this reason, the wire 1 (Fig. 3a) be knurled or raised beaded at these points 6.

The process of inserting the contact pins 1 into the insulating plate 2 is shown in FIG. The contact wire 1 can e.g. B. be in a magazine like the clips of an office stapler, which are covered by a lacquer coating are connected to each other. The contact wire 1 is first inserted into the pre-punched base plate 2 introduced (Fig. 4b) and in the same operation the end protruding through the plate 2 (Fig. 4c) knocked down. With an appropriate choice of the insulating material of the base plate, squeezing of the Contact wire 1 (Fig. 5) suffice. The contact wires 1 prepared in this way are then used in the dip-soldering process connected to the metal foil 3 in a known manner. For special designs (e.g. many connection points, insulating material laminated on both sides) a two-stage arrangement according to FIG. 6 is conceivable. A modification in the production method for the plug contacts 1 is shown in FIGS. The base plate 2 is only perforated and the contact pin in the manner shown (Fig. 8 a to 8 c)

set, bent and soldered to the printed conductor 3.

In order to keep the pitch between the individual contact wires 1 as small as possible, the _; Eontaktstifte 1 arranged on both sides (Fig. 9). The automatic insertion of the contact pins 1 into the insulating material plate 2 is carried out from two sides of the insulating material plate 2 simultaneously or one after the other: by turning the plate 2. When immersion soldering, the corresponding row of pins whose contact ends are on the soldering side must be covered.

Another modification in the arrangement of the contact pins 1 is shown in FIG. The pins 1 are, with the same size, staggered in depth. The contact tips are therefore different far from the insulating plate 2. When inserting the pins 1 into the mating connector, not shown First the contacts above overcome the initial force of the counter springs, and then the remaining contact pins follow. This reduces the large insertion force that is required for connectors with many con, clock points is common, distributed between two successively effective partial forces.
