Description
Die Erfindung bezieht sieh auf eine Kentakt!erstelle zum Hemmen von elektronischen Bauteilen in oberflichenmontierbaren Behausen.The invention relates to a detection device for locking electronic components in surface-mountable housings.
Auf dee, Harkt befinden sich Kontaktierstellen die in ' grollen Stacksahlen eingesetzt werden. 8ie all« haben . metallische federnde Kontakte die im Abstand der • Bautollanschlämme in Kunststoff eingegossen oder . eingesteckt sind.There are contact points on the rack that are inserted into large stacking rods. They all have metal spring-loaded contacts that are cast or inserted into plastic at a distance from the building material.
Dieme Fassungen haben alle den Nachteil daß die elektrische Waglange zwischen dem zu messenden Bauteil und dem anderen Ende der Kontaktfeder «ehr lange ist O AiMi). Dadurch sind sie für hochfrequente Anwendungen nicht geeignet.These sockets all have the disadvantage that the electrical distance between the component to be measured and the other end of the contact spring is very long (AiMi). This makes them unsuitable for high-frequency applications.
Weitere Nachteile von denen alle brannten Kontaktstellen mindestens einen aufweisen&igr;Further disadvantages of which all burned contact points have at least one&igr;
- Unterschiedlich lange Kontaktfedern und dadurch unterschiedliche SerieninduktlvitAten.- Contact springs of different lengths and therefore different series inductances.
- Sehr hohe Federkraft der Kontaktfedern wodurch große Gefahr der Verbiegung der AnmchluAbeinchen besteht.- Very high spring force of the contact springs, which means there is a high risk of the connecting legs becoming bent.
- Sehr niedrige Federkraft und/oder nicht veredelte Oberfläche der Kantaktfedern. Dadurch entstehen unregelmäßig hohe Übergangswiderstunde zum zu messenden Bauteil.- Very low spring force and/or non-finished surface of the contact springs. This results in irregularly high transition resistance to the component to be measured.
Der Erfindung liegt die Aufgabe zugrunde eine Kontaktstelle zu schaffen die möglichst alle oben genannten Nachteile vermeldet und trotzdem einfach In der Herstellung und im Gebrauch ist sowie eine lange Lebensdauer verspricht.The invention is based on the task of creating a contact point that avoids as many of the above-mentioned disadvantages as possible and is nevertheless simple to manufacture and use and promises a long service life.

Bauteiles.The aim was achieved by manufacturing the contact strips from hard gold-plated, hardened Cu-Be strips which, due to the half-circle bend, have an electrical path length of only 2.3 mm (6,7). The targeted interaction between the bending shape mentioned above and the hardening ensures a better contact quality (< 0.05 % ohm) while at the same time there is no risk of bending the component connections.
f: In the event that the component to be sealed is pressed onto the contact point with a particularly high force, the plastic center bar prevents the component from being pressed down too deeply and thus the contacts or the connectors of the component from being bent.

Diese Kentaktstelle ist gekennzeichnet durch etwa lOea lange Cu-Be-Streifen <1> die an eine« Ende zu eine« Halbkreis eit eine« Durchmesser von 1.SaM <2) gebogen sind. Das freie Ende dieser Streifen wird ie Abstand der SHD-Bauteileenschiasse auf eine Linge von Sem in nichtleitenden Kunststoff <3> elngwapritzt.
Entsprechend des Abstandes der zwei Reihen der Bauteil»anschlüsse sind ebenso zwei Reihen <4) der oben beschriebenen Kontakte gegenüber fest verbunden. ZmIsehen den beiden Reihen verlauft ein 3wa breiter und 1.2«»Pfoher Kunststoffstreifen <S).We are applying for protection of the contact surface for surface-treated components <8MD components>.
This contact point is characterized by approximately 100 long Cu-Be strips <1> which are bent at one end to form a semicircle with a diameter of 1.5 mm <2). The free end of these strips is injected into non-conductive plastic <3> at a distance of 1 mm from the SHD component clamps.
In accordance with the distance between the two rows of component connections, two rows <4) of the contacts described above are also firmly connected opposite each other. A 300 mm wide and 1.2 mm thick plastic strip <S) runs between the two rows.
