DE1011957B - Plug receiving contact - Google Patents

Description

GERMAN

The invention relates to a plug on receiving contact, in particular for as spring and male connectors marked plug connections in telecommunication devices. There are many such connectors Commonly used to identify telecommunications equipment with numerous circuit connections, ζ. B. for the purpose of replacement in the event of defects, disconnect the power supply by pulling the plug or by pressing the. To connect the plug to the circuits. The circuit connections or the devices are used for this purpose at the point of separation to a large number of contact blades or contact springs embedded in insulating material brought up, which make electrical contact when making the plug connection.

In known designs of such contact connections two contact springs are arranged on both sides of the rigid contact blade, their contact pressure is reinforced by additionally arranged resilient parts. This particular construction requires a relatively large amount of non-ferrous metal and a considerable amount of space. this however, is based on the latest findings of progressive design and manufacturing practice undesirable.

The invention enables a low expenditure of non-ferrous metals and good contact if the space required is very small.

The invention consists in> that the contact-making Parts of the spring strip are designed as rigid contact lugs and the contact lugs each several, preferably two, arranged one behind the other at a large distance in relation to their width, have elevations facing the contact knife.

Steel springs pressing against the contact blades are used in the usual way to achieve the necessary Contact pressure. The individual contact lugs and: the steel springs are designed in such a way that that moving the contact lugs and steel springs against each other is not possible. These are the contact lugs with recesses and the steel springs with tabs that fit into the recess Mistake.

Crimped beads are used to increase the stability of the contact lugs.

Lierendem material is attached. With regard to this contact knife 1 there is between the known, and the embodiment according to the invention no fundamental difference ;.

In the previous version according to Fig. 1, two mirror-inverted contact springs are provided, which are designated with 2 and 3 and which are pressed by a steel spring 4 against the contact blade will. The contact springs 2 and 3 are made of resilient sheet brass. Fig. 1 clearly shows that a relatively large amount of non-ferrous metal for both contact springs and a large amount of space is necessary for the purpose of accommodating the parts and achieving resilient mobility. The two Contact points are arranged opposite one another on both sides of the contact blade 1.

In the embodiment according to the invention according to Fig. 2, strictly speaking, at. the part 5 no longer of a contact spring spoken. This part is therefore in the further description with contact lug designated. As can be seen, only one rigid contact tab 5 is necessary for making contact. The quality improvements on the material are lower because the contact tab is not off Fedenme & siiig needs to exist. The contact tab 5 is inserted into the holder 12 made of molded material in such a way that it is once captive in a Z-shape and on the other hand their position in the recess of the holder * is clearly determined. Through this When the contact blade 1 is pulled out, the contact lug 5 holds itself. The contact lug 5 has As Fig. 2 clearly shows, in the case shown there are two elevations 7 and 8 arranged one behind the other, which serve to make contact. Their distance is kept large in relation to the width of the flag. When pushing in of the contact knife 1, the elevation 7 rubs the oxide skin on the surface of the knife

so that when the knife is pushed in further Up to the elevation 8, a point of the compact knife necessary for making contact is rubbed bright. the Spring 6 generates the. desired contact pressure on the two in the longitudinal direction of the contact blade 1 arranged one behind the other, establishing the contact Raises 7 and 8. The good contact is supported by the fact that the contact knife are kept movable by small amounts in their holder, not shown.

The steel leaf spring 6 shown in FIG. 3 has a tab 10 bent over by 180 ° at one end on, which fits into the recess 9 of the Konitakt flag 5 according to Fig. 4. After insertion into the holder 12 can fields 6 no longer move. Falling out is thus · definitely prevented.

To increase the stability of the contact lugs 5 Corrugations pressed into them serve 11.
