Spring element for plug connections.

The innovation relates to spring elements for electrical Plug connections with lugs for attaching electrical conductors. 'Such spring elements are for example in the Telephony technology is used and can also be used to connect connecting lines within telephone stations wi'e also for connecting the supply lines, such as the

Handset cords, can be used.

The well-known spring elements usually wear them as a port setting Base one or more U-shaped pre-bent approaches into which Ends of stripped conductors are inserted, after which the free ends of the U-shaped lugs are bent so far that they enter into a mechanically rigid contact connection with the conductor.

The purpose of the innovation is to create spring elements for electrical plug connections Equip them in such a way that they can also be connected to other than insulated flexible conductors, for example to the cable runs printed or etched circuits, can be connected »

This purpose is achieved in that the base of the spring element carries two parallel approaches that are rigidly connected to one another over a portion of their length and with at least part of this area and with their free ends over

P ₀ protrude the outlines of the spring element.

The spring element equipped according to the invention can therefore be in advantageously, depending on the design of its approaches, a plug-in connection, a snap-in connection or a clamp connection with rigid carrier plates, so that further connections are now made with the help of contact blades

can be. In this way it is possible to print on a or etched circuit board to form a socket strip to which another printed or etched circuit board can be connected with the usual blade contacts

can. Of particular advantage in the arrangement according to the innovation it is that part of the rigid connection of the two approaches and the free ends of the approaches beyond the outline of the Protrude spring element. In this way it is ensured that if, for example, the spring element with its two free ends is inserted into two bores until it stops, all other parts of the spring element opposite the carrier plate Have enough freedom so that the rebound of the legs of the spring element is not hindered in any way.

The lugs can expediently lie essentially parallel to the direction of insertion of the mating contact. The approaches will be arranged on the side of the spring element opposite the push-in side, so that the advantage of there is absolutely free access to the slide-in side.

_: , But the approaches can also be essentially perpendicular to the direction of insertion of the mating contact. With this arrangement, the carrier plate will come to lie parallel to the direction of insertion, so that the insertion side will only be absolutely free if, for example, the spring element protrudes with part of its legs over the side delimitation of the plate »

The advantage of this arrangement, however, is that the approaches when establishing or releasing the plug-in connection are not subjected to tension or pressure, but only to shear, so that, for example, with a pure plug-in connection between the " ^! Lugs and the carrier plate or with a snap-fit connection a stress exceeding the holding force of this connection is avoided.

According to a further thought of the innovation, the free length the approaches can be greater than the thickness of a carrier plate for printed or etched circuits. The spring element can then advantageously grab with its two approaches through holes in the carrier plate and the approaches can be attached to the

■ '-' ■■■ can be improved, for example in the course of a wave soldering process, and ensures an absolutely rigid position of the spring element with respect to the carrier plate.

Appropriately, the approaches can be designed as flat lobes Ausgrc-2 ^{: ί} ·. These tabs, which then have to be matched in their width to the intended bore diameter in the carrier plate, are adequately held in the plate and can simply be bent over to establish the contact.

For better insertion of the approaches into the holes in the carrier plate the ends of the lobes can be tapered. This execution in no way burdened the production, the can be produced with the cutting of the spring element without additional effort, facilitates the assembly considerably.

The innovation is explained in more detail below with reference to the exemplary embodiments.

Show it:

arranged approaches,

FIG. 2 shows a spring element with lugs arranged perpendicular to the insertion direction.

The spring element 1 in Fig. 1f§ has two flat parallel lugs 3 on its base 2 , which engage through bores 4 of a carrier plate 5. In the area 6 closest to the base, the attachments are rigidly connected to one another, so that they cannot be pushed into the carrier plate further than the lower limit of this area. The ends 7 of the lugs 3 conically converge on one another, so that, as the side elevation shows, it is easier to push them into the bores, which have a diameter that corresponds to the width of the lugs. As can be seen from the figure, the spring element is in this arrangement with its insertion direction perpendicular to the carrier plate »so that the insertion side 8 is freely accessible.

The spring element 9 in Pig. 2 is arranged so that the The direction of insertion runs parallel to a carrier plate 10. From the base 11 of this peder element go parallel to Insertion direction two flaps 12 and 13, their right-angled bent ends form the lugs 14. The two tabs 12 and 13 simultaneously form the area of the tabs in which they are rigidly connected to each other. As in the page outline 2 can be clearly seen, these approaches also provide for the freedom of movement of the legs of the Spring element required distance between carrier plate and Federelenent 9 safe. As in FIG. 1, the lugs 14 protrude through bores in the carrier plate 10 and become bent in both arrangements on the side opposite the spring element.
