Description

Care is taken that the openings in the bearing body are only a little larger than the meandering bent feathers.

According to a further development of the invention, the two springs of a pair of springs are located in this way with their flat sides against each other, that their meandering turns aligned in opposite directions and. This prevents the individual turns of the folded springs from getting caught.

Claims (5)

Compression spring also inserted into the bores. Continue to exhibit this 1. Contact device for simultaneous pen-like feeler elements, likewise pen-like approach feel a multitude of contact points by means of 5, which approaches up to the level of the other upper grid-like in a carrier block inserted area of the carrier block and to which spring Pushbutton elements for telecommunications systems, sets of electrical conductors can be connected in particular to scan the contact points. Such a device has the disadvantage of printed circuit boards, due to the fact that the pin-like contacts: ement a relatively large amount of space indicates that the probe elements need as in io, so that a grid division, d. H. one one plane meandering flat ones. Area distribution of the contact elements in Springs (7) are formed, which in bores (4) the support block corresponding to the very small of the bearing body (1) and in openings (S, 6) of the grid division, d. H. the very narrow distribution of Cover plates (2, 3) in pairs with their contact points on a modern printed circuit board, not flat sides are guided next to one another and 15 is possible. Furthermore, an electrical connection can be made on both sides of the carrier block (1, 2, 3) with their circuit of electrical conductors to these spring ends (71 or 72) which run out in a straight line in the known device only through elements to form probe tips (spring end 71) a movable jumper wire can be carried out, as with on the one hand and by connecting lugs (spring end 72) the resilient evasion of the probe tip of the probe on the other hand over the carrier block (1, 2, 3) also the electrical connection protrude. an electrical conductor serving approach of the tactile 2. Apparatus according to claim I, characterized in that the element is moved. indicates that the cover plates (2, 3) in the object of the invention is now to provide a contact Height of the holes (4) and to create with respect to this device, which in a simple manner have narrower openings (5 or 6), in which the very small grid dimensions of modern printed circuit boards chen the springs (7) can be adapted to their straight spring or modern assemblies ends (71 or 72) are performed. and which ensure reliable contact with the rest 3. Device according to claim 1 or 2, da- elements with the contact points to be scanned through characterized in that the two springs (7) ensures. each of a pair of springs with their flat 30 According to the invention, this is achieved by Sides lie against one another that their meander-shaped that the probe elements as in one plane meander-shaped gen turns are aligned in opposite directions. curved flat springs are formed, which are in 4. Device according to one of the preceding stanchions of the bearing body and in openings of the claims, characterized in that the cover plates are each paired with their flat sides the springs (7) of a pair of springs are guided by the 35 adjacent and on both sides of the both legs of a U-shaped bent part are carrier block with their straight lines forms are, the free leg ends of the probe spring ends to form probe tips on the one hand to form peaks. and from connecting lugs on the other hand over the 5. Device protrude according to one of the preceding gerblocks. A particular advantage of the claims characterized in that the 4 ° finding consists in that each probe element consists of two the probe tips forming spring ends (71) for individually resilient probe springs, so that a Creation of rounded sensing points - preferably good contacting even with the type of contact to be sensed are bent by 180 °, places with an uneven surface is guaranteed. The springs form a direct electrical transition from the probe tip to the wiring connection. B. when several connecting elements are connected in series occur to be avoided. Because the resilient, so meandering curved area of the 50 springs guided in a hole in the bearing body The invention relates to a contact device, i. H. is supported in the longitudinal direction of the spring direction for simultaneous scanning of a plurality ensures that the end of the spring, which one of contact points by means of a grid-like form in a Trä connection lug for wiring, while gerblock inserted resilient probe elements not moved for the scanning process. It is without it Telecommunication systems, especially for scanning the 55 further possible, these connecting lugs, d. H. the Contact points of printed circuit boards. straight spring ends with printed Solder for simultaneous scanning of a large number of or etched conductor tracks. In particular It is known contact points to provide a device, the solution according to the invention enables a very great deal use, which consist of a plate-like carrier - small grid division of the field of probe elements, block consists in which carrier block in certain 60 Advantageously, the cover plates in Distribution probe elements are used, which at the height of the holes and compared to these narrower üff-Aufselzen of the carrier block z. B. on one to check in which the springs on their straight lines fendc or printed circuit board to be scanned are guided resiliently after spring ends. Preferably support yourself can give, so that a contact of all the springs with their outer meander-shaped Probe elements with the contact points to be scanned 65 turns on these cover plates. By the is likely. These tactile elements consist of the presence of special guide openings, pins, those with cylindrical attachments in bores allow the springs to be used even with very small dimensions of the carrier block are guided and not dodging by one, especially if still on it
