Connecting contact

The invention relates to a contact with in two Contact points that can be aligned in various positions, for a one-sided or double-sided, to accommodate a Connector or a printed circuit board

Interconnects.

In particular, the invention relates to a contact for a connector of the type mentioned, in which the contact points can be aligned at different heights, so that individual electrical connections when Insertion or extraction of a plug or a printed circuit board at different times come about or be interrupted. In the following description, the term "position" denotes or "height" that is, the different spatial arrangement of the active contact points in relation to contacts on a connector *

In known connectors of the type mentioned can one-piece or subdivided, fork-shaped contacts by means of different heights in the cells a connector socket set protrusions formed therein, the elastic material from which the socket exists, must be elastically deformed in order to insert the contacts.

When using one-piece fork contacts, the possible applications for such connectors are limited to the extent that they are used to accommodate plugs or printed circuits with double-sided, different contact areas are not suitable. In addition, the design and manufacture of the Sockets with the training for attaching the contacts at different heights in the cells quite difficult and cumbersome. .Furthermore, this leads to the insertion of the contacts required elastic deformation of the Version to premature wear and tear or material fatigue of the same, so that the contacts are not too can often be replaced or adjusted in their height.

The invention is based on the object of eliminating these disadvantages and creating a resilient contact, which enables independent contact

put on both sides of the longitudinal axis of a connector at different heights so that the connector For holding plugs or printed circuits with contact surfaces arranged on one or both sides suitable is.

According to the invention, a contact of the type mentioned is characterized by a rigid shaft which is attached to one end in a connector and at the other end in a contact head with both sides of the longitudinal axis deö contact points formed at different heights " runs out, through training for twist-proof fastening of the contact and for alignment of the connector in a constant, predetermined Position, and · through training to secure contact against longitudinal displacement, the contact for adjusting the height of the active contact point from the The connector socket can be removed and returned to the socket after a rotation of 180 ° around its longitudinal axis can be used and the position of the connection part on the connection side of the connector is independent of the selected position of the connection point remains unchanged.

When inserting and removing the contact according to the invention, the material of the socket is not stressed in any way, so that the contacts can be exchanged as often as desired or adjusted in the height of their active contact points a simple molding process without the need for the complicated mold cores that were wrong for the production of known connector sockets of the type mentioned b < ^{T: .3t.}

In an advantageous embodiment of the invention has a contact on a rigid shaft which terminates at one end in a connecting part, the Shape can be designed as desired depending on the type of connections to be made. Two staring at that Shaft protruding guide parts serve to secure the contact against rotation and the connecting part to align in a certain position. A spring-elastic one that is integral with the rigid shaft Leg serves to secure the contact against longitudinal displacement and for this purpose engages on one projection formed in a cell of the connector socket, so that the contact by pressure or Can't move the train up or down

Those arranged symmetrically on either side of the longitudinal axis of the contact, but at two different heights active contact points are made of a spring-elastic Strips formed in such a way as to ensure adequate contact pressure at all times is.

To adjust the height of the contact point, the contact is turned by 180 ° in the respective cell, so that one or the other of the two contact points arranged at different heights into the operative position koeat.

The following is an embodiment of the invention described on the basis of the drawing. Show in it:

Fig. 1 is a side view of a cell of a connector socket shown in section seated contact according to the invention,

Fig. 2 is a front view of the contact of Fig. 1 and

401884/1127

3 shows a representation of the contact in its two positions rotated by 180 ° with respect to one another.

In the illustrated embodiment of the invention, there is a contact with two lying at different heights Contact points for a single- or double-sided connector made in one piece from a conductive, resilient one Punched material. The punched-out material is at an end piece to a contact head in the form of an elastic Loop 1 is formed with two active contact points 2 and 3 located at different heights. To the Achieving the desired elasticity of the contact head this is laminated from a double sheet metal strip. The active contact points 2 and 3 are each through divided a longitudinal section 4, so that so that in the There is a two-point contact point at both height positions.

For inserting the contact into a cell 5 o a connector it is introduced into this from its front side. It has a resilient leg 6 for the grip on one of two projections 7 or 8 formed in the cell 5. The leg 6 carries two stops 9 and 10, one of which is any downward displacement and the other is a displacement prevented upwards, so that the contact is held immovably in the axial direction.

Two protruding tongues 11 and 12 are used to reliably guide the contact when it is inserted into the cell 5 and then to secure it against twisting. For this purpose there is a corresponding sliding guide in the cell formed for the tongues 11 and 12. At the same time, the tongues 11 and 12 serve to form a connecting part 13 to keep the contact aligned in a certain position.

409884/1127

In the position of the contact _i in which the higher contact point 3 is in its operative position, the guide tongue 11 is supported on a step 14 formed in the cell 5 in order to secure the contact against twisting.

The setting of the contact point of the contact in the respective other height is done in the following way: In the cell containing a contact 5, a suitable tool is inserted to with this the resilient To push leg 6 aside and thus to detach from the projection 7 (Fig. 1). In this to stare Shank 15 of the contact pushed back position one holds the leg 6 firmly and the contact can now without Pull out difficulty on the front or top side of the connector. The one pulled out of the connector Contact is now rotated by 180 ° around its longitudinal axis and then reinserted into cell 5, until the leg 6 now engages on the projection 8 (Fig. 3). In this arrangement there is now the higher one Contact point 3 in the operative position, instead of, as shown in FIG. 1, the deeper-seated contact point

The sides of the connector at which introduced the tool used to expand the contact or at which contact of the cell is pulled out, 0ind Torstehend given of an illustrative example of forming only in Fora. Furthermore, although it is stated above that the various files of the contact are made in one piece with one another, they can, however, instead also be made individually and joined together in some way to form an integral whole.

The invention is not limited to the described embodiment. example, but extends to various modifications and changes of the same.
