Description

The invention relates to a connection element for a ! Carrier plate »which, at least in areas close to the runner, has conductive surface separation center, in particular with Ceramic or glass substrates with protective shields.

In electrical engineering, especially communications engineering there is the problem of uncomplicated circuits arranged on glass or ceramic substrates using interconnection technology and to be able to install them reliably in electrical devices and systems.

It is therefore an object of the invention to provide a connection element for create such substrates, which in particular the electrical and mechanical connection of such substrates made possible with a printed circuit board.

To solve this problem, a connection element is the initially named type according to the invention designed such that a substantially S-shaped curved sheet metal strip with his first loop acting as a resilient hammer, making contact with a conductive surface section the plate is attached and soldered to the surface section and that the free leg of the second loop is extended to a connecting rod.

One of the advantages of such a connection element is this to see that the substrate is for connection to the connection element not with breakthroughs, e.g. for inserting Connection elements must be provided and that by the

arise only because the connection elements through the crossbars exactly at the distance of the haste division of a printed circuit board from each other be kept away. The connecting element after the invention also makes it possible in an advantageous manner to have visual circles on one side of the substrate with those on the other side of the substrate by placing both legs of the first loop of the Connection element soldered to appropriate conductive layers v / ground.

The invention is explained in more detail below with reference to 6 pigures. They each show seen in an oblique view and shown greatly enlarged

Pig. 1 several together by crossbars at their two ends connected connection elements;

The free leg of the second Loop 5 of the connecting element is extended to form a connecting rod. To facilitate handling and fixation of the connection elements, several connection elements are connected to one another by transverse webs 2 lying next to one another at a certain grid spacing. In this way punch or etch the connection elements out of sheet metal in one operation. I) ie connecting elements are also, in order to make it easier to separate the crosspieces 2, connected to these via notches 3. After attaching it a plurality of connecting elements connected to one another by the two webs clasped onto a substrate 7 the first loop 4 of each connecting element resiliently and the subr-Btrat in an associated area near the edge contacted with his leg attached to the crosspiece 11 12 a conductive surface portion 9 of the substrate formed by the loop 4 of the connection element resilient clip 10 holds the connecting element with off, sufficient strength in its predetermined position, so that further aids for fixing the connection elementB to for soldering the leg 12 to the surface section of the substrate are not required. After attaching the connecting elements connected via the two transverse webs 2, the transverse webs the connecting elements in the correct position adjust to their associated surface sections, the crosspiece 11, which the legs to be soldered the connecting elements connects to one another, separated. If you make the individual surface sections 9 larger than the area of the leg 12 which it touches, when the surface sections are soldered to the legs 12, the Leg 12 in so-called all-round soldering completely enclosed by solder 13 and good strength of the soldered connection achieved.
