The hiring refers to a screwless, self-resilient connecting terminal for the retention of screwless fasteners, "in which a connecting leg starts at an angle from a main leg and a connecting leg of these is provided with a barb-like serrated edge and inclines towards the main leg extending ( Kleankontaktschenkel is bent, which holds the connecting end of an electrical conductor on the main limb kleaneud, and furthermore in the apex zone between the main limb and the Yerbindungsschenkel an insertion opening for the connection end is provided.

A screwless, self-resilient connection terminal of the type described at the beginning is known, for example, from British patent specification 688,338. In the inschlwSTri shown here, too, let vea a Ssaptschenlcel bent over a Terbi & Dimgsschenkel r - the KlemüEontaktschenkel in the direction of the main leg. 2> he Elenakontaktschenkel in this patent is formed from a leg extended beyond the clamping contact and with the formation of a Yerkroplung on the main leg, provided with a mounting hole leg part of the width of the main leg corresponding inherent width. As a result, the clamping contact leg is inevitably narrower than the main leg of the contact clamp. The clamping blade of the terminal contact shackle (is designed as a fork blade having a single clamping channel.

It is obvious that when you introduce it the connection of an electrical conductor through a rear in the Yerbinduagsseheitel swl see the

Main leg and the connecting leg arranged Insert the lead-through opening exactly through it must in order to get the connection end exactly in the area of the wedge edge of the clamping contact leg. Venn The connection end is sewn in dl® putty the wedge chord introduces, i.e. if by improperly inserting the connecting thread into the Clamp this including that comes to lie crooked, it can happen that the relatively narrow clamping contact leg does not carefully touch the connection end detected, so that not only the secure clamp hold of the connecting conductor, but also a secure contact is designed in embossing

Now, starting from a contact brake of this known type, there is now the task of the present Fire in it to create a contact terminal capable of catching the inserted contact end of the connecting lighter in every insertion position not only keep it safe, but also a perfect one To ensure contact.

The goal of the innovation is achieved in advantageous

more adhesive way by the fact that you clamping edge of the one

() Hehrzagschneide is formed, with the between The clamping channels left with the prongs or prongs enclose an angle of no more than 90 °.

If one forms according to the proposal of the hiring the clamping edge of the new terminal as Hehr-tooth or Hehrzack cutting edge, then it plays at all with a cutting edge designed in this way no more questions as to whether the connection end of the conductor end that connects to this connection terminal without screws

exactly in the longitudinal direction of the main leg or below an angle to this from the Sinführungsseite the Klemm © * her is introduced. Due to the large number of serrated tips arranged on the cutting edge becomes even if the connection end is inserted at an angle at least one of those points - in practice

there are, however, within several - not only clammy, but also securely making contact with the connection end act. This is also favored by the fact that the cutting edge is one of the Gtosaut width of the Main schenkeis has the appropriate length, and that this cutting edge over its entire length is designed as a more sack cutting edge.

Ee is therefore the innovation with extremely simple, However, highly effective smocks have succeeded, without an additional expense a® so far not achieved reliable support and Komtaktgabe the inclusion end to achieve, thereby through this Solution a connection terminal that is extremely useful in practice for screwless mounting of in » conclusive has been created, which is not only characterized by its simplicity, but also by virtue of its duration. their highly reliable effect particularly characterized and thereby in particular also according to the terminal British patent 688 356 mentioned at the beginning is far superior *
