Socket with metal housing and additional switching contact

In the case of sockets »as used in ffutnk and television technology, e.g. for the connection of τοη magnetic recorders are used, the requirement is occasionally made that "when inserting of the device plug the connection of the metal socket housing is separated with an insulated contact spring, i.e. this contact spring when the plug is removed is connected to the socket housing and thus connected to ground.

Sockets are known in which this additional switching contact is attached to the outside of the circumference of the socket housing and an insulating pin projecting into the inside of the socket is provided for actuation. A much more useful solution is the object of the innovation, with which it is proposed to provide the Isolierstoffeinsätζ receiving the contact springs of the socket along a surface line with a slot for an approximately bow-shaped arched leaf spring, which is attached to the housing bottom with its arched section in the free space between Insert and housing protrudes and at its other end makes contact with a metal, essentially rigid intermediate member which forms the opposite contact for a second leaf spring, which is housed in a central recess of the insert and carries an insulating pin o engages concave area of the curvature of the first spring. This construction is characterized by its extraordinary compactness. Since the switching contact is also inside the box, good protection against damage during transport and the like is guaranteed *

An embodiment of the 3i @ uerung is in the following

Hand of the drawing, on a much larger scale explained in more detail, the section of the new socket in the lower half and a for sale in the upper half of the associated connector shows.

In the drawing, 1 denotes the insulating material insert which receives the contact springs 2 of the socket and which is surrounded by a metal housing 3. The insert is provided along a surface line with a slot 4 for an approximately bow-shaped arched leaf spring 5 which, with the help of a rivet eyelet 6, is attached to a "downward-facing! Pocket?" With its arched part 5 * this leaf spring protrudes into the free space between the insert 1 and the housing 3% while its free end * contacts a metal, essentially rigid intermediate member 8, which is also carried by the bracket 7 'This intermediate member forms the mating contact for a second leaf spring 9 »which is accommodated in a central recess Io of the insert 1 and whose free end is bent at right angles towards the intermediate member 8 for this purpose. The leaf spring 9 carries an insulating pin 11 which is guided through a recess 8 * in the intermediate member 8 and engages in the concave area of the curvature of the spring 5.

When inserting the plug 12, its middle contact pin is to be thought of as lying in front of or behind the plane of the drawing, the leaf spring 5 supported on the intermediate member 8 deformed by the collar 12 * of the plug that the Insulating pin 11 performs a movement in the direction of the arrow. This results in a movement of the leaf spring 9, during which its free end lifts off the intermediate member 8, whereby the conductive connection of the spring 9 with the intermediate member 8, the spring 5 resting on it and the metal socket housing 3 is interrupted. When the plug is pulled out, the spring 5 returns to its original position and thus also the insulating pin 11, so that the conductive connection between the files 9 * 8, 5 and 3 is restored.
