Description

. The invention relates to calibrating an electrical contact for installation in an electrical outlet or a connection Buchs ^·: in which an electrical plug pin and a plug engaging

is cash. ",

According to the invention, a contact for installation in an electrical plug-in element or a connection socket is provided, which consists of a rigid plate-like base part made of metal ei * mutually opposite, essentially rigid arms, which extend parallel to the base part at a distance therefrom and each on one end integrally connected to the base part by a web and having opposite to its said web end portions which wipe a Einführhals for receiving a "arms einzufindenden plug pin or plug form, each arm with Λ em G ^ imdteil a as Spring torsion bar acting web is connected ", so that with relative movement of the arms on the web, an axial rotary movement is transmitted.

In previously known contacts with opposite one another Irmen that should be able to move relative to one another for receiving a pin or plug are either off made of thin, flexible metal so that they can easily be

or they can be bent via the end to be connected to the base part of the contact. In the present invention however, the relative movement results from the rotary movement of the connecting webs acting as torsion spring bars. Duren change The width and / c the thickness of the webs can be used to determine the amount of movement and therefore also the amount of movement on the inserted pin or Change the tensioning effect exerted on the plug as required.

Preferably the arms extend substantially parallel to the base part, and the connecting webs extend essentially at right angles to adjacent sections of the "Basic part and the arm".

At its free end, each arm is with an inward extending bopenfSreigen portion is formed, the convex surface of which faces that of the other arm, these surfaces moving an inserted plug pin. ti tea handle press on and without the inserted pin they see each other at a distance.

The aria of contact can extend longitudinally » have edges that are normally in contact with one another and serve to adjust the distance between the convex Pichen * tt «old»

The invention will be described in the following with reference to that in the enclosed The example shown in the drawing is described in more detail »

The contact according to the invention consists of metal, 8.B. made of phosphor bronze, and has a plate-like base part 1 with a pair of opposing arms 2, 3 »which are integrally connected to the base part via webs A-, S at one end. As can be seen from the drawing, the webs are rectangular ⁴ g and extend substantially at right angles to the arms and the base.

At their other ends, the A- "me are designed with flanges 6,7, which extend essentially at right angles to the arms and extend 8,9 ^ it inwards and outwards have directed sections which are mutually overlying convex surfaces with a s ^ hul ^ er 10, 11 result and thereby a narrowing bz'- '. form an import destination which a pin or plug can be inserted.

The shoulders 10, 11 are arranged parallel to one another at a distance, before the pin or plug is inserted, and their inward mobility is due to the attachment of the external faculties 2a, yes the arms are limited to each other.

Ατι rear end is the base part with an axially extending Wiring attachment 12 formed and at its front end with a rectangular sleeve 13, which through Bending of front end portions of the base occurs.

The contact is suitable for installation in the cavity or the Recognition of an electrical socket or connection socket and is held in a connected position by a spring tongue 14, the spring tongue having its free earth one in the cavity or acted upon in the recess provided stop. The inward movement of the contact is made possible by the protruding Approach 13 limited.

The width of the pin or Plug is slightly larger than the distance between the shoulders 10, 11, and accordingly the Are "must purely relatively movable by a limited amount. The arms are essentially rigid and their movement is limited. by means of a rotary movement communicating the webs $ ·, 5 acting as rotary f ed only from e, so that the arms are pressed elastically against one another and cause good mechanical and electrical loading of the inserted pin or plug .

Since the sections acting on the pin or plug the ATie, i.e. d: e shoulders 1C, 11 in "rest position" between rieh show some decency «, these parts can as desired appropriately covered with money '"of other metal.

The contact can be installed in an opening or recess in a socket or female terminal, and built-in contact, the sleeve 13 is seated in a rechteckfSrmigen portion at dee the terminal pin-receiving end of the opening or recess and thus serves to correct aligned arrangement of the contact. In addition, the sleeve 13 also serves to guide the pin of the electrical component to be connected to the socket or connection socket.
